Good Morning!, its time for practiseSafeHex's most incompetent co-worker!
Todays contestant is a very special one.
*sitcom audience: WHY?*
Glad you asked, you see if you were to look at his linkedin profile, you would see a job title unlike any you've seen before.
*sitcom audience oooooooohhhhhh*
were not talking software developer, engineer, tech lead, designer, CTO, CEO or anything like that, No No our new entrant "G" surpasses all of those with the title ..... "Software extraordinaire".
*sitcom audience laughs hysterically*
I KNOW!, wtf does that even mean! as a previous dev-ranter pointed out does this mean he IS quality code? I'd say he's more like a trash can ... where his code belongs
*ba dum tsssss*
Ok ok, lets get on with the show, heres some reasons why "G" is on the show:
One of G's tasks was to build an analytics gathering library for iOS, similar to google analytics where you track pages and events (we couldn't use google's). G was SO good at this job he implemented 2 features we didn't even ask for:
- If the library was unable to load its config file (for any reason) it would throw an uncatchable system integrity error, crashing the app.
- If anything was passed into any of the functions that wasn't expected (null, empty array etc.) it would crash the app as it was "more efficient" to not do any sanity checks inside the library.
This caused a lot of issues as some of the data needed to come from the clients server. The day we launched the app, within the first 3 hours we had over 40k crash logs and a VERY angry client.
Now, what makes this story important is not the bugs themselves, come on how many times have we all done something stupid? No the issue here was G defended all of this as the right thing to do!
.. and no he wasn't stoned or drunk!
G claimed if he couldn't get the right settings / params he wouldn't be able to track the event and then our CEO wouldn't have our usage data. To which I replied:
"So your solution was to not give the client an app instead? ... which also doesn't give the CEO his data".
He got very angry and asked me "what would you do then?". I offered a solution something like why not have a default tag for "error" or "unknown" where if theres an issue, we send up whatever we have, plus the file name and store it somewhere else. I was told I was being ridiculous as it wasn't built to track anything like that and that would never work ... his solution? ... pull the library out of the app and forget it.
... once again giving everyone no data.
G later moved onto another cross-platform style project. Backend team were particularly unhappy as they got no spec of what needed to be done. All they knew was it was a single endpoint dealing with very complex model. There was no Java classes, super classes, abstract classes or even interfaces, just this huge chunk of mocked data. So myself and the lead sat down with him, and asked where the interfaces for the backend where, or designs / architecture for them etc.
His response, to this day frightens me ... not makes me angry, not bewilders me ... scares the living shit out of me that people like this exist in the world and have successful careers.
G: "hhhmmm, I know how to build an interface, but i've never understood them ... Like lets say I have an interface, what now? how does that help me in any way? I can't physically use it, does it not just use up time building it for no reason?"
us: "... ... how are the backend team suppose to understand the model, its types, integrate it into the other systems?"
G: "Can I not just tell them and they can write it down?"
**
I'll just pause here for a moment, as you'll likely need to read that again out of sheer disbelief
**
I've never seen someone die inside the way the lead did. He started a syllable and his face just dropped, eyes glazed over and he instantly lost all the will to live. He replied:
" wel ............... it doesn't matter ... its not important ... I have to go, good luck with the project"
*killed the screen share and left the room*
now I know you are all dying in suspense to know what happened to that project, I can drop the shocking bombshell that it was in fact cancelled. Thankfully only ~350 man hours were spent on it
... yep, not a typo.
G's crowning achievement however will go down in history. VERY long story short, backend got deployed to the server and EVERYTHING broke. Lead investigated, found mistakes and config issues on every second line, load balancer wasn't even starting up. When asked had this been tested before it was deployed:
G: "Yeah I tested it on my machine, it worked fine"
lead: "... and on the server?"
G: "no, my machine will do the same thing"
lead: "do you have a load balancer and multiple VM's?"
G: "no, but Java is Java"
... and with that its time to end todays episode. Will G be our most incompetent? ... maybe.
Tune in later for more practiceSafeHex's most incompetent co-worker!!!31 -
"You mean to tell me that you deleted the class that holds all our labels and spin boxes together?" I said exasperatedly.
~Record scratch.mp3
~Freeze frame.mp4
"You're probably wondering how we got to this stage? Let's wind back a little, shall we?"
~reverseRecordSound.wav
A light tapping was heard at the entrance of my office.
"Oh hey [Boss] how are you doing?" I said politely
"Do you want to talk here, or do you want to talk in my office? I don't have anyone in my office right now, so..."
"Ok, we can go to your office," I said.
We walked momentarily, my eyes following the newly placed carpeting.
Some words were shared, but nothing that seemed mildly important. Just necessary things to say. Platitudes, I supposed you could call them.
We get to his office, it was wider now because of some missing furniture. I quickly grab a seat.
"So tell me what you've been working on," I said politely.
"I just finished up on our [project] that required proper saving and restoring."
"Great! How did you pull it off?" I asked excitedly.
He starts to explain to me what he did, and even opens up the UI to display the changes working correctly.
"That's pretty cool," admiring his work.
"But what's going on here? It looks like you deleted my class." I said, looking at his code.
"Oh, yeah, that. It looked like spaghetti code so I deleted it. It seemed really bulky and unnecessary for what we were doing."
"Wait, hold on," I said wildly surprised that he thought that a class with some simple setters and getters was spaghetti code.
"You mean to tell me that you deleted the class that organizes all our labels and spin boxes together?" I said exasperatedly.
"Yeah! I put everything in a list of lists."
"What, that's not efficient at all!" I exclaimed
"Well, I mean look at what you were doing here," he said, as he displays to me my old code.
"What's confusing about that?" I asked politely, but a little unnerved that he did something like this.
"Well I mean look at this," he said, now showing his "improved" code.
"We don't have that huge block of code (referring to my class) anymore filling up the file." He said almost a little too joyously.
"Ok, hold on," I said to him, waving my hand. "Go back to my code and I can show you how it is working. Here we are getting all the labels and spin boxes into their own objects." I said pointing a little further down in the code. "Down here we are returning the spin boxes we want to work with. Here and here, are setters so we can set maximum and minimum values for the spin box."
"Oh... I guess that's not that complicated. but still, that doesn't seem like really good bookkeeping." He said.
"Well, there are some people that would argue with you on that," I said, thinking about devRant.
He quickly switches back to his code and shows me what he did. "Look, here." He said pointing to his list of lists. "We have our spin boxes and labels all called and accounted for. And further down we can use a for loop to parse through them."
He then drags both our version of the code and shows the differences. I pause him for a moment
"Hold on, you mean you think this" I'm now pointing at my setters "is more spaghetti than this" I'm now pointing at his list of lists.
"I mean yeah, it makes more sense to me to do it this way for the sake of bookkeeping because I don't understand your Object Oriented Programming stuff."
...
After some time of going back and forth on this, he finally said to me.
"It doesn't matter, this is my project."
Honestly, I was a little heart broken, because it may be his project but part of me is still in there. Part of my effort in making it the best it can be is in there.
I'm sorry, but it's just as much my project as it is yours.16 -
Just sharing my experience of my spontaneous interview with Facebook. I'm not good at writing these but here you go :)
- I was working as an Android dev and didn't have much knowledge in algorithms nor competitive programming, never ever interviewed with big companies.
- a random day on LinkedIn, a recruiter from Facebook contacted me
- I ignored it for few week because I thought it's so out of my league, then somehow, out of blue, I had a thought of giving it a try, so I did
- passed first round
- start studying algorithms a little for phone interview in 3 weeks
- recklessly took the phone interview
- passed
- start studying intensively (while working fulltime) for the on-site interview in 2 months
- almost got the job, they gave me one more chance by a followed up interview
- messed up the last chance real bad
- failed!!!
- Initially I just wanted to give it a try, but the fact that I failed at very very last chance, frankly, bothers me a bit. Maybe I will interview with FB or big companies if I have chance later, but I know for sure that the studying had made me a much better dev. All the code I write now is much more efficient (I think), I can and not anymore afraid of reading complicated code.
- Overall, it does takes a lot of time (~4 months studying while working fulltime), but also benefits myself a lot though I didn't get the job, so basically, good experience, but better if I got the job 😁
Oops, wanted to write a few lines and it's a long post already.. I should stop here :D9 -
*Cuts 7 slow lines of code down to 1 fast line of code*
*Looks around to see if coworkers can see me*
*Pumps both fists in the air*7 -
Lads, I will be real with you: some of you show absolute contempt to the actual academic study of the field.
In a previous rant from another ranter it was thrown up and about the question for finding a binary search implementation.
Asking a senior in the field of software engineering and computer science such question should be a simple answer, specifically depending on the type of job application in question. Specially if you are applying as a SENIOR.
I am tired of this strange self-learner mentality that those that have a degree or a deep grasp of these fundamental concepts are somewhat beneath you because you learned to push out a website using the New Boston tutorials on youtube. FOR every field THAT MATTERS a license or degree is hold in high regards.
"Oh I didn't go to school, shit is for suckers, but I learned how to chop people up and kinda fix it from some tutorials on youtube" <---- try that for a medical position.
"Nah it's cool, I can fix your breaks, learned how to do it by reading blogs on the internet" <--- maintenance shop
"Sure can write the controller processing code for that boing plane! Just got done with a low level tutorial on some websites! what can go wrong!"
(The same goes for military devices which in the past have actually killed mfkers in the U.S)
Just recently a series of people were sent to jail because of a bug in software. Industries NEED to make sure a mfker has aaaall of the bells and whistles needed for running and creating software.
During my masters degree, it fucking FASCINATED me how many mfkers were absolutely completely NEW to the concept of testing code, some of them with years in the field.
And I know what you are thinking "fuck you, I am fucking awesome" <--- I AM SURE YOU BLOODY WELL ARE but we live in a planet with billions of people and millions of them have fallen through the cracks into software related positions as well as complete degrees, the degree at LEAST has a SPECTACULAR barrier of entry during that intro to Algos and DS that a lot of bitches fail.
NOTE: NOT knowing the ABSTRACTIONS over the tools that we use WILL eventually bite you in the ASS because you do not fucking KNOW how these are implemented internally.
Why do you think compiler designers, kernel designers and embedded developers make the BANK they made? Because they don't know memory efficient ways of deploying a product with minimal overhead without proper data structures and algorithmic thinking? NOT EVERYTHING IS SHITTY WEB DEVELOPMENT
SO, if a mfker talks shit about a so called SENIOR for not knowing that the first mamase mamasa bloody simple as shit algorithm THROWN at you in the first 10 pages of an algo and ds book, then y'all should be offended at the mkfer saying that he is a SENIOR, because these SENIORS are the same mfkers that try to at one point in time teach other people.
These SENIORS are the same mfkers that left me a FUCKING HORRIBLE AND USELESS MESS OF SPAGHETTI CODE
Specially to most PHP developers (my main area) y'all would have been well motherfucking served in learning how not to forLoop the fuck out of tables consisting of over 50k interconnected records, WHAT THE FUCK
"LeaRniNG tHiS iS noT neeDed!!" yes IT fucking IS
being able to code a binary search (in that example) from scratch lets me know fucking EXACTLY how well your thought process is when facing a hard challenge, knowing the basemotherfucking case of a LinkedList will damn well make you understand WHAT is going on with your abstractions as to not fucking violate memory constraints, this-shit-is-important.
So, will your royal majesties at least for the sake of completeness look into a couple of very well made youtube or book tutorials concerning the topic?
You can code an entire website, fine as shit, you will get tested by my ass in terms of security and best practices, run these questions now, and it very motherfucking well be as efficient as I think it should be(I HIRE, NOT YOU, or your fucking blog posts concerning how much MY degree was not needed, oh and btw, MY degree is what made sure I was able to make SUCH decissions)
This will make a loooooooot of mfkers salty, don't worry, I will still accept you as an interview candidate, but if you think you are good enough without a degree, or better than me (has happened, told that to my face by a candidate) then get fucking ready to receive a question concerning: BASIC FUCKING COMPUTER SCIENCE TOPICS
* gays away into the night53 -
Not so much screaming as staring in disbelief, mumbling profanity in his direction...
When my department lead said "I don't think this unit testing hype or code reviews make much sense, it's more efficient to just make a checklist and test the application yourself"
This was the QA department of an aerospace company, we wrote NDT software to do image recognition on xrays of alloy welds and micrometer laser measurements on fuel tank surfaces. Software which is quite mission critical, a single misrecognized welding fault could literally cost up to half a billion dollars — not to mention that it's a very sabotage & espionage sensitive industry.
After raising some hell he was replaced though.3 -
I've been writing PHP for more then 10 years. So, one fine day while having coffee with new tech manager...
Manager: huh, you've been programmer for very long time. Can you explain how echo works?
Me: err.. Echo. Spit out string. (show some example code on my phone)
Manager: I mean, I want to know, which part in C++ code in PHP engine. (trying to impress with jargons)
Me: I don't know. But why?
Manager: As programmer, you need to know, so you can echo more efficient.
Me: ... Errr... Ok... (I've been echo-ing for more then decade. Is there a way to make echo more efficient?)12 -
5 Types Of Programmers
1.The duct tape programmer
The code may not be pretty, but damnit, it works!
This guy is the foundation of your company. When something goes wrong he will fix it fast and in a way that won’t break again. Of course he doesn’t care about how it looks, ease of use, or any of those other trivial concerns, but he will make it happen, without a bunch of talk or time-wasting nonsense. The best way to use this person is to point at a problem and walk away.
2.The OCD perfectionist programmer
You want to do what to my code?
This guy doesn’t care about your deadlines or budgets, those are insignificant when compared to the art form that is programming. When you do finally receive the finished product you will have no option but submit to the stunning glory and radiant beauty of perfectly formatted, no, perfectly beautiful code, that is so efficient that anything you would want to do to it would do nothing but defame a masterpiece. He is the only one qualified to work on his code.
3.The anti-programming programmer
I’m a programmer, damnit. I don’t write code.
His world has one simple truth; writing code is bad. If you have to write something then you’re doing it wrong. Someone else has already done the work so just use their code. He will tell you how much faster this development practice is, even though he takes as long or longer than the other programmers. But when you get the project it will only be 20 lines of actual code and will be very easy to read. It may not be very fast, efficient, or forward-compatible, but it will be done with the least effort required.
4.The half-assed programmer
What do you want? It works doesn’t it?
The guy who couldn’t care less about quality, that’s someone elses job. He accomplishes the tasks that he’s asked to do, quickly. You may not like his work, the other programmers hate it, but management and the clients love it. As much pain as he will cause you in the future, he is single-handedly keeping your deadlines so you can’t scoff at it (no matter how much you want to).
5.The theoretical programmer
Well, that’s a possibility, but in practice this might be a better alternative.
This guy is more interested the options than what should be done. He will spend 80% of his time staring blankly at his computer thinking up ways to accomplish a task, 15% of his time complaining about unreasonable deadlines, 4% of his time refining the options, and 1% of his time writing code. When you receive the final work it will always be accompanied by the phrase “if I had more time I could have done this the right way”.
What type of programmer are you?

Progression in mindset of a developer trough professional life:
1. I'm going to make my code so efficient and beautiful that everyone will envy it!
2. I'm going to make sure I keep separation of concern.
3. I'm going to make my code at least maintainable for other developers.
4. Well shit. At least it works, for now.3 -
I think the coolest project I did was a few years ago, it was actually a Minecraft plugin.
I decided to learn Java for Minecraft, and a few months after I started learning Java, I was approached by someone who'd like to work with me to create this full-blown Gun Game style gamemode for Minecraft. I made it clear I didn't have the most knowledge, but I was willing to learn.
We began working on the project, the projects main class was bigger than any project I had worked on. Within a few months, it became one of the more popular plugins out there, even though we were still in an alpha mode. Had nearly 1,000 servers running the plugin, over 10k+ players total testing out the plugin.
Cause of this project, I learnt how to properly organize my code, how to make it efficient, learnt how to network, learned how to properly secure and verify anything being sent by the client, working with dependencies, adding features that can support a bunch of other plugins that other developers had, and a bunch more.
Sadly we couldn't finish the plugin anymore, so we gave someone else the source code who has kept it updated to this day. (I know I didn't provide much insight into what I'm saying and just gave a general overview, got a killer headache.)2 -
What an antiquated idea it is for us to all have to go to the same room/sets of rooms to do our job? Yeah sure let's just get each other sick and distract each other ALL FUCKING DAY so that we're more efficient in an office. Bullshit.
Next up, 9-5. We're goal driven, not time-driven, and driven by deadlines. Nothing about our job can we only do between 9am and 5pm. I'm more creative at 1am, anyway! These are systems people created when they wrote with FUCKING FEATHERS. Grow up, Planet Earth.
Not to mention that once you have kids you need to cater your timings around them. Up at 7, leave at half past, maybe seeing your son for a minute, if he's woken up. In work 9-5, even when the next piece of work isn't specced out yet, twiddling your thumbs. And even when it is you can't get it done because people bore you to death with stories about how they're going to a party on the weekend. And it's hard to code when you're dead from boring stories. Shove your stories up your arse.
Then you leave at 5, home at 6, put the little one to bed at 7 and sit there from 7-11 thinking if I'd worked these hours I could have spent all afternoon with my son.
It's such lunacy.
Just give me tasks that estimate to about 40 hours work, and I'll do it in a week. Hell I'll even spend a day in the office and we'll call it 45 hours. I'll work the first almost two entire days straight and spend 3 days with my son. You get the same value as an employer. I can maybe actually work on a project at home, or do a hobby, or, you know, SEE MY KID.
Fuck you, Offices. And fuck you, 9-5 fallacy.

Sooo, in my 5 years of high school, I had 5 different IT teachers...
Now, in Italy Highschool goes from 14 to 19 years old, I started programming some days after becoming 13, and "programming" classes begin on the third year, so I had quite a headstart on my classmates...
Now, for the third year, I had an awesome teacher, he noticed I was ahead and... Bored, so he gave me some extra stuff to study, he's the only teacher I've learnt anything from, it was awesome, very stingy with grades, but getting a perfect score with him was so satisfying.
Fourth year, the new guy was old, very old, at least 70, his lessons were just him talking about how programming was when he was young.
But then... During the second half of the fourth year I changed class due to bullying under a teacher's advice, and HE happened...
My new IT teacher, one of the most ignorant, awful people I ever met...
He's literally the reason I only went back to that school once, because another teacher needed help with a course...
One day I made the HUGE mistake to say that his "while(i <10000000000000);" wasn't very efficient for making a delay, because it didn't free the CPU, and since then:
- I never got more than 7 out of 10 at his tests
- He insulted me in front of the whole class
- He sabotaged the oral part of my final exam, shouting that he hated D'Annunzio when he saw he was in the literature part of my thesis (needed him to connect to WW2, and the Memex, that then allowed me to start talking about PCs and programming, my thesis was about the influence of lisp on modern programming languages), loudly chatting with other teachers when I was trying to keep calm (a teacher who knows me quite well, and was there to see my "performance" thought I was going to snap at some point), distracting the english teacher when I was exposing the english part of my thesis and pressuring the commission to give me 99 instead of 100 out of 100
So yeah, he almost made me hate the only thing I'm good at, undervaluing my work and my skills, undervaluing and humiliating me as a person, and I think that if I meet him again I might spit on his face...
So yeah, my biggest "programmer enemy" was a person that then did everything in his power to make my last year and a half of highschool hell
Now I can gladly say that with the help of my tutoring, some of my university colleagues are starting to appreciate programming, and my engineer friends ask for my help when they need advices about their code, and it's giving me motivation to keep doing it and becoming a better programmer to keep up with their expectations4 -
KISS.
Keep it simple, stupid.
At the beginning the project is nothing but an idea. If you get it off the ground, that's already a huge success. Rich features and code quality should be the last of your worries in this case.
Throw out any secondary functionality out the window from day 0. Make it work, then add flowers and shit (note to self: need to make way for flowers and shit).
Nevertheless code quality is an important factor, if you can afford it. The top important things I outline in any new non-trivial project:
1. Spend 1-2 days bootstrapping it for best fit to the task, and well designed security, mocking, testing and extensibility.
2. Choose a stack that you'll most likely find good cheap devs for, in that region where you'll look in, but also a stack that will allow you to spend most of your time writing software rather than learning to code in it.
3. Talk to peers. Listen when they tell that your idea is stupid. Listen to why it's stupid, re-assess, because it most probably is stupid in this case.
4. Give yourself a good pep talk every morning, convincing you that the choices you've made starting this project are the right ones and that they'll bring you to success. Because if you started such a project already, the most efficient way to kill it is to doubt your core decisions.
Once it's working badly and with a ton of bugs, you've already succeeded in actually making it work, and then you can tackle the bugs and improvements.
Some dev is going to hate you for creating something horrific, but that horrific thing will work, and it's what will give another developer a maintenance job. Which is FAR, far more than most would get by focusing on quality and features from day 0.9 -
TLDR;
Wrote a slick scheduling and communication system allowing me to assign photography resources based on time and location.
I'll tell you a little secret ... I'm not actually a dev. I'm a photographer, pretending to be a dev.
Or ... perhaps it's the other way around? (I spend most of my time writing code these days, but only for me - I write the software I use to run my business).
I own a photography studio - we specialize in youth volleyball photography (mostly 12-18 year old girls with a bit of high school, college and semi-pro thrown in for good measure - it's a hugely popular sport) and travel all over the US (and sometimes Europe) photographing.
As a point of scale, this year we photographed a tournament in Denver that featured 100 volleyball courts (in one room!), playing at the same time.
I'm based in California and fly a crew of part-time staff around to these events, but my father and I drive our booth equipment wherever it needs to go. We usually setup a 30'x90' booth with local servers, download/processing/cashier computers and 45 laptops for viewing/ordering photographs. Not to mention 16' drape and banners, tons of samples, 55' TVs, etc. It's quite the production.
We photograph by paid signup only - when there are upwards of 800 teams/9,600 athletes per weekend playing, and you only have four trained photographers, you've got to manage your resources!
This of course means you have to have a system for taking sign those sign ups, assigning teams to photographers and doing so in the most efficient manner possible based on who is available when the team is playing. (You can waste an awful lot of time walking from one court to another in a large convention center - especially if you have to navigate through large crowds - not to mention exhausting yourself).
So this year I finally added a feature I've wanted for quite some time - an interactive court map. I can take an image of the court layout from the tournament and create an HTML version in our software. As I mouse over requests in one window, the corresponding court is highlighted on the map in another browser window. Each photographer has a color associated with them. When I assign requests to a photographer, the court is color coded with the color of the photographer. This allows me to group assignments to minimize photographer walk time and keep them in a specific area. It's also very easy to look at the map and see unassigned requests and look to see what photographer is nearby.
This year I also integrated with Twilio and setup a simple set of text shortcuts that photographers can use to let our booth staff know where they are, if they have memory cards that need picking up, if they need water/coffee/snack, etc. They can also move assignments on their schedule or send and SOS for help if it looks like they aren't going to be able to photograph a team.
Kind of a CLI via the phone. :)
The additions have turned out to be really useful and has made scheduling and managing the photographers much easier that it was in the past.18 -
"Enigma machine kep private the communications done by Nazi. It was a really difficult code to break because it changed each day. There was a man in England, Alan Turing, who broke it. He's nowadays known as one of the fathers of the Computer Science. I will show in the next lessons how you can simulate Enigma coder just with an easy C program of 60-70 lines. In the WW2 this was considered a military-level safe code. Thanks to mathematicians, computer scientist and analyst and thanks to their work in the last 60 year, you have access to a systems of several orders of magnitude more efficient and secure when you buy a videogame online."
That really fucking inspired me.8 -
TL;DR: I dont work in IT, but I code at work, and the non-IT higher-ups lack of knowledge shows brutally.
So I work in aviation, not IT. Through coincidences, I was tasked to work on our flight plan distribution logic years ago, which was then written in BRL (Business Rule Language). In lockdown 2020, I finally started to learn "real" programming with Python, but soon shifted to Java. Which was good, since all of a sudden a few months ago the company ditched BRL and the godawful IBM ODM IDE for... Java and IntelliJ. Nice. BUT my teammates have zero clue about Java and no real inclination to learn it by themselves. So I have been appointed their mentor, despite me stating Im still a beginner myself. Its somewhat doable, I get the hard problems, they do basic maintenace, basically renaming variables and stuff. One of my yearly goals is to make sure a completely new guy is able to do everything I do by september. It took a LOT to talk them out of it.
In my last yearly review I got some flak for not "selling" myself to other teams enough, whatever that means. So, as a learning project, I designed a new intranet page for our department in Javascript. Its loved by all. It has links to all the stuff we need woth a nice interface and built in tools to make work easier and more efficient. I did it on my own, in my spare time, simply because I was fed up with the old crap and it was an enormously good learning opportunity. Now they want to give some other guy the responsibility over that page/tool because apparently it is "not in my process team description". They even planned a day for me and him so he can "learn Javascript then". Suuure...
I also did a digital checklist tool as a webapp. All this runs from a local folder, no server at all because reasons. I made it work. Now they want it integrated into some other tool some other guy made. He wrote his tool in PHP entirely so merging the two will take considerable time. Which I told them multiple times. No, it does not take about two hours.
Sometimes, comrades, sometimes....
Im still grateful for the opportunity to code at work but the lack of knowledge really REALLY shows. My goal now is to talk management into paying for a Java course for me (they are very expensive here). That way, they get a better employee and I get more knowledge and an actual certificate thats worth something. Usually in this company, this has higher chances of success than straight up asking for more money.
Sorry for the long story, but it felt good just typing it all out, even if nobody reads this.4 -
Does anyone else get so self conscious about writing neat, clean and efficient code that you get demotivated because you always think "there's a better way to do this".
The cleanest code is no code at all. 😂8 -
I just got called into my bosses office. Apparently I was too "direct" with one of my code reviews and now the other developer feels put down and demotivated. All I did was point out some areas of the code that could be cleaner and more efficient, if you can't handle that maybe you shouldn't be a developer. If you can't objectly look at your mistakes and learn from them you won't be very useful either.
I am not your mother, I don't care about your feelings!6 -
An application based on a single MySQL stored procedure that contained all the application business logic inside of it (plus a poor webapp that simply called it). The stored procedure had 97 (yes, NINETY SEVEN) parameters... and about half of them were boolean flag used for enabling/disabling another parameter. I think that Uncle Bob could follow you holding an AK-47 if he saw that. The saddest part is that the shit was written by a guy having a PhD in computer science, and he knew that was bad, but the boss asked him to do it in that way. The guy left the company before I joined it and I had to maintain that crap. Guys, the first time I saw it I thought that should be a joke. Code generated by decompilers was easier to read, maybe even Brainfuck. I tried complaining with the boss but she said that the system was wonderful and very efficient. This was one of the reasons I moved to another company after some months.3

Okay, just because I'm the only one under 35, single, and only white/hispanic guy on this team doesn't give you the right to interrupt me mid sentence IN my meeting. No disrespect to the developers from India and this may just be a culture conflict where I am outnumbered in my company but I don't understand the how some of these guys can't just be polite or respect others opinions(this is just from my experience with 90 or so developers from India and I don't believe in blanketing all Indians as this way just these 90 plus I do love the food).
Don't hijack MY meeting and then completely derail where I was going and disregard my solution without listening to the whole thing for an idea that isn't even solution but adds more work for both parties involved. You may have been working here for 5 years, but I worked in the actual department where we're building the new process and solution to a problem I've worked on. I understand the user since I WAS ONCE THAT USER for a good 8 months. And on top of that you can barely code efficient, or complex SQL statements. You're nothing more than fucking script kiddies and this whole IT department is joke. I apologize if the rant isn't really that coherent, I'm not very good at typing rants with my adrenaline running hot.14 -
I've been working exclusively from home for over 2 years now. I've been seeing several posts from people talking about adjusting to working from home, so I figured I would compile a list of tips I've learned over the years to help make the adjustment easier for some people.
1) Limit as many distractions as possible. WFH makes it much easier to get distracted. If you have roommates/family members at home, ask them politely to leave you alone while you're working. Make sure the TV is turned off, put your phone on silent, etc.
2) Take regular breaks. I find it easier to accidentally go hours without taking a real break from work. Try working in half hour intervals, and then taking 5-10 minute breaks. Read an article, watch a youtube video, grab some coffee/tea, etc.
3) When you eat lunch, eat it away from your computer. I often find myself eating lunch trying to wrap up fixing a bug, which makes it feel like I never really "took a lunch." Lately I've been trying to step away and do something else completely unrelated to work.
4) Get ready for work like you normally would. It's very easy to wake up, throw on your favorite pair of sweats and sit at the computer with messy hair half awake "ready" to start the day. Instead try doing your normal morning routine before sitting at your computer. It will help your mind and body go into "it's time to work" mode.
5) Keep your work area clean. I find it very difficult to work when my workspace is cluttered. Studies have shown working in a messy place tend to make us less efficient.
6) Keep your work area work related. Try to only have the things you need for work in your workspace. If you're working from your personal computer this can be difficult. I always end up with camera/music equipment left over from the previous night's photo editing/jam sessions. So try to clean off your desk when you're done for the night so it's ready for work in the morning.
7) Prepare for meetings. I have alarms set 10 minutes in advance so I can go from programming mode to meeting mode. During this time I'll go to the bathroom, grab a snack, water, mute all my email notifications, close any non essential programs, get my code ready if I need to present it.
Stuff is hard & stressful right now, but hopefully these tips will make it a bit easier. If anyone else has any good tips please share them.5 -
Part 1: https://devrant.com/rants/4210605
So let's talk about these tasks we were assigned. Ms Reliable and Mr DDTW's friend who I just realized I haven't named yet were in charge of programming communications. Ms Enabler and Mr DDTW were in charge of creating the vehicle subclasses for the new variants we were instructed to build. Each one had to handle one variant, and we estimated that both of these would be about the same difficulty (Ms Enabler's one turned out to be a little harder).
I like Ms Enabler, and she's a good friend, although she isn't the best at problem solving and her strengths as a dev lie in her work ethic and the sheer amount of theory she knows and can apply. These just so happened to be the exact opposites of my strengths and weaknesses. Within a few days of having assigned the tasks, she came up to me asking for help, and I agreed. Over the following couple of weeks I'd put in quite a lot of hours reviewing the design with her, and we'd often end up pair programming. It was more work for me, but it was enjoyable and overall we were very efficient.
The other two girls in the group were also absolutely fine this sprint. They simply did the work they had to and let us know on time. Outside of some feedback, requests, bugfixes, and mediating disagreements, I didn't have to do anything with their tasks.
A week and half into the sprint and everybody else has their part almost in an MVP state. As Mr DDTW hadn't said or shown anything yet, I asked if he could push his stuff to the repo (he got stuck with this and needed help btw), and what does he have?
A piece of shit "go to this location" algorithm that did not work and was, once again, 150 lines of if statements. This would not have been such a massive deal if THE ENTIRE PREVIOUS SPRINT HAD BEEN DEDICATED TO MAKING THE CODE DO THIS IN A SENSIBLE WAY. Every single thing that this guy had written was already done. EVERY SINGLE THING. A single function call with the coordinates would let the vehicle do what he wrote but in a way THAT ACTUALLY WORKED AND MADE THE TINIEST BIT OF FUCKING SENSE. He had literally given so few shits about this entire goddamn project that he had absolutely zero clue about what we'd even done last sprint.
After letting this man civilly know through our group chat about his failures, giving him pointers on what's wrong and what he can use and telling him that he should fix it by the end of the week, his response?
"I'll try"
That was it. Fuckass was starting to block us now, and this was the first sign of activity he's given since the sprint started. Ms Enabler had finished her work a fucking week ago, and she actually ASKED when she ran into trouble or thought that something could be improved. Mr DDTW? He never asked for shit, any clarification, any help, and I had let everybody know that I'm open. At least the other two who didn't ask for shit ACTUALLY DID SOMETHING. He'd been an useless sack of shit for half a semester in three separate projects and the one time he's been assigned something half important that would impact our grades he does this. I would not stand for it.
I let him know all this, still civil (so no insults) but much less kind, capped with "Stop fooling around. Finish this by the of the week." which probably came off as a threat but his shithead kinda had it coming.
He was actually mad. Dropped a huge faux-apologetic spiel in the chat. Why couldn't I just trust him (his code was garbage and he was constantly late without explanation), his work was almost done (it wasn't and if he'd started he'd understand the scope of what he was assigned), that the problem was that I'm a condescending piece of shit (bruh), and was suddenly very interested in doing work. Literally everybody ignored him. What was funny was seeing the first questions and requests for help after that spiel. I obliged and actually answered what he asked.
The end of the week came and went he'd just uploaded more garbage that didn't work. I had foreseen this and, on top of everything else, had been preparing his section of the work done by myself and properly. Thus came a single commit from me with a working version of the entire module, unblocking the entire team. I cannot imagine the sheer hatred for this man at that moment for the commit message to simply be:
"judgement"
And with that, all I got was a threat to report me to the professor for sabotaging his work. The following day our group got an email from the professor, with no explanation, asking for an almost-immediate video conference. Group chat was a shitshow of panic, as nobody knew what was going on. Least of all Mr DDTW.
Once again, I'm approaching the word limit so to be continued in part 3 (hopefully of 3)7 -
So I just found out that my colleague who I often have to work with does not use a debugger to troubleshoot any bugs at all. Actually, he does not even run or test his code locally either with prints or something similar. He just commits java code directly on bitbucket, no source control, without making sure it compiles and then he runs a CI provided by devops that takes 4 freaking hours to run because he bloated that shit up somehow.
I suggested politely to help him find a more efficient approach and to use my hardware setups for speeding up his work because I assume it must be pretty painful to work with, but he just refused.
That and those "seniors" with 10 years Linux development XP in the embedded field who don't know basic commands like ls, cat and touch and code in notepad.
Fucking me, who the hell am I working with and can someone please end me?6 -
Le me: "my code is awesome! The way I did XY and Z is insanely cool, efficient, and maintainable."
Le Boss: "yeah so let's schedule a code review next week."
Le me : "... fuck, Fuck, FUUUUCK!"
Internal Screaming3 -
When I learnt programming, sugar was still made out of salt and hence not used in coffee.
Also, we didn't have source level debuggers, only the "print" method. However, compiling was also slow. It was faster and more convenient to go through the program and execute the statements in one's head. This helped understanding what code is doing just by reading it. It also kept people from trial and error programming, something that some people fall for when they resort to single step debugging in order to understand what their own code is even doing.
Compiling was slow because computers in general were slow, like single digit MHz. That enforced programming efficient code. It's also why we learnt about big Oh notation already at school. Starting with manual resource management helped to get a feeling for what's going on under the hood.20 -
My code is always a battle between best practices and what I assume would be the most efficient way to do things4

!rant but history
I found this old micro controller: The TMS 1000 (from 1974). The specs: 100-400kHz clock speed, 4-bit architecture, 1kB ROM and 32 bytes (!) RAM. According to data sheet, you sent the program to TI and they gave you a programmed controller back - updates to the once upload program were impossible, but an external memory chip was possible.
I'm glad we have computers with more processing power and storage (and other languages than assembler) - on the other hand it enforced good debugging before deployment and and efficient code.
Data sheet: http://bitsavers.org/components/ti/...6 -
Sometimes dirty code is more efficient than clean code.
If features get dropped frequently and requirements change every few days, writing best-practices, tested code is wasted time. Learned that in my first job where I thought the other devs were all bad. Until I realized their bad code pays my salary, and my clean code takes more time to develop.6 -
Apparently some freaking man in my ex-team tried to learn Vim because he thought he could become more efficient but he spend more than two weeks trying it while delivering poor quality code with extra spaces, bad indentation and extra "wq" strings10

Data Engineering cycle of hell:
1) Receive an "beyond urgent" request for a "quick and easy" "one time only" data need.
2) Do it fast using spaghetti code and manual platforms and methods.
3) Go do something else for a time period, until receiving the same request again accompanied by some excuse about "why we need it again just this once"
4) Repeat step 3 until this "only once" process is required to prevent the sun from collapsing into a black hole
5) Repeat steps 1 to 4 until it is impossible to maintain the clusterfuck of hundreds of "quick and simple" processes
6) Require time for refactoring just as a formality, managers will NEVER try to be more efficient if it means that they cannot respond to the latest request (it is called "Panic-Driven Development" or "Crappy Diem" principle)
7) GTFO and let the company collapse onto the next Data Engineering Atlas who happens to wander under the clusterfuck. May his pain end quickly.2 -
My code review nightmare?
All of the reviews that consisted of a group of devs+managers in a conference room and a big screen micro-analyzing every line of code.
"Why did you call the variable that? Wouldn't be be more efficient to use XYZ components? You should switch everything to use ServiceBus."
and/or using the 18+ page coding standard document as a weapon.
PHB:"On page 5, paragraph 9, sub-section A-123, the standards dictate to select all the necessary data from the database. Your query is only selecting 5 fields from the 15 field field table. You might need to access more data in the future and this approach reduces the amount of code change."
Me: "Um, if the data requirements change, wouldn't we have change code anyway?"
PHB: "Application requirements are determined by our users, not you. That's why we have standards."
Me: "Um, that's not what I ..."
PHB: "Next file, oh boy, this one is a mess. On page 9, paragraph 2, sub-section Z-987, the standards dictate to only select the absolute minimum amount of the data from the database. Your query is selecting 3 fields, but the application is only using 2."
Me: "Yes, the application not using the field right now, but the user stated they might need the data for additional review."
PHB: "Did they fill out the proper change request form?"
Me: "No, they ...wait...Aren't the standards on page 9 contradictory to the standards on page 5?"
PHB: "NO! You'll never break your cowboy-coding mindset if you continue to violate standards. You see, standards are our promise to customers to ensure quality. You don't want to break our promises...do you?"7 -
Hey I got reminded of a funny story.
A friend of mine and me were in internships in the same company. The company was specialized in territory resources management (managing water for agriculture, money to build industrial zones...). He got the interesting internship (water predictory modeling) and I got... The repairs of a reference sheet manager that never happened to work. It was in C# and ASP.NET and I was in second year of CS. I expected the code to be nice and clear since it was made by a just graduated engineer with +5years of studies.
I was very wrong.
This guy may never have touched a web server in his life, used static variables to keep sessions instead of... well... sessions, did code everything in the pages event handlers (even LinQ stuff et al) and I was told to make it maintainable, efficient and functional in 2 months. There were files with +32k LoC.
After 1week of immense despair, I decided I will refactor all the code. Make nice classes, mapping layer, something close to a MVC... So I lost time and got scoled for not being able to make all the modifications as fast as in a cleanly designed code...
After 4 weeks, everything was refactored and I got to wait for the design sheets to change some crystal report views.
At this moment I began to understand were was the problem in this company.
My friend next door got asked to stop his modeling stuff for an emergency project. He had to make an XML converter for our clients to be able to send decentralized electrics bills, and if it was not completed within a week, they would no longer be able to pay until it is done.
This XML converter was a project scheduled 5 years before that. Nobody wanted to do it.
At the same time, I was waiting for the Com Department to give me the design views.
I never saw the design views. Spent one month implementing a golden ratio calculator with arbitrary precision because they ain't give me anything to do until the design were implemented.
Ended with a poor grade because "the work wasn't finished".2 -
SICK AND TIRED OF READABILITY VS. EFFICIENCY!!!!!!!
I HAD TO SEPARATE A 4 LOC JSON STRING, WHICH HAD AN ARRAY OF A SINGLE KEY-VALUE PAIRS (TOTAL OF 10 OBJECTS IN THE ARRAY).
ITS READABLE IF YOU KNOW JSON. HOW HARD IS TO READ JSON FORMAT IF YOU GET YOUR STYLE AND INDENTATION PROPERLY?!?
SO I HAD TO
BREAK THE POOR FREAKING JSON APART TO A FUCKING DIFFERENT YAML FILE FORMAT ONLY SO I CAN CALL IT FROM THERE TO THE MAIN CONTROLLER, ITERATE AND MANIPULATE ALL THE ID AND VALUES FROM YAML BACK TO MATCH THE EXPECTED JSON RESPONSE IN THE FRONT END.
THE WHOLE PROCESS TOOK ME ABOUT 15 MINUTES BUT STILL, THE FUCKING PRINCIPLE DRIVES ME INSANE.
WHY THE FUCK SHOULD I WASTE TIME AT AN ALREADY WORKING PIECE OF CODE, TO MAKE IT LESS EFFICIENT AND A SLIGHTLY BIT MORE READABLE?!? FML.5 -
Continuation from :
https://devrant.io/rants/835693/...
Hi everybody! I am sorry that as a first time poster I am building 2 long stories, but I really like the idea of connecting with other people here!
Well, as I was mentioning before, I got a job in Android development and had a blast with it. Me and the developer clicked and would spend our time discussing PHP, the move to other stacks (I was making him love the idea of Django or Spring Java) games, bands and cool stuff like that. This dude was my hero, his own stack was developed in a similar MVC fashion that he had implemented from scratch before for many projects. It was through him that I learned how to use my own code (rather than frameworks and other libraries) to build what I wanted. I seriously thought that I had it made with a position that respected me and placed me in the lead mobile development position of the company. Then it happened. He had taken 2 weeks of unauthorized leave, which was ok since he was best friends with the owner of the company, those 2 along another asshole started it so they could do whatever they wanted. And I could not make much progress without him being there since there were things that he needed to do, that I was not allowed, for me to continue. When he came back I was quickly rushed to the owner of the company's office to discuss my lack of progress. The lead developer was livid, as if he knew that he had fucked up. He blamed the whole thing on me (literally told the owner that it was my fault before I was summoned) and that we lost 2 weeks of business time because I did not had the initiative to make progress on my own. I felt absolutely horrible, someone that I had trusted and befriended doing something like that, I really felt like shit. I had mad respect and love for this guy. It got heated, I showed the owner the text messages in which I showed him my pleas to led me finish the parts that were needed while he was away. Funny enough, he acted betrayed. After that it was 3 months of barely talking to one another except for work related stuff. He got cold and would barely let me touch the internal code that he was developing. It was painful. The owner kept complaining about progress and demanded that I do a document scanner for the company, which was to be attached to their mobile application. Not only that but it had to be done with OpenCV. Now, CV is great, but it is its own area, it takes a while to be able to develop something nice with it that is efficient and not a shitstorm.
I had two weeks.
Finished in one. After burning my brain and ensuring that the c++ code was not giving issues and the project was steady I turned it in...to their dismay. And I say so because I felt that they gave me such a huge project with the intention of firing me if it was not done. After that it was constant shit from the owner and the lead developer. I was asked then to port the code to the IOS version. I had some knowledge of it already so I started working on it. Progress was fast since the initial idea was already there and I really love working on Apple devices. And when I was 70% done the owner decided to cut me loose. At first he cited things such as lack of funding and him being unable to pay my salary. I was fine with that even though I knew it was not true. So at the time I just nodded and thanked the company for my time there. Before I left, he decided to blame it on me, stating that if they were not producing money that it was perhaps my fault. I lost my shit, and started using my military voice to explain to him how a software company is normally ran. Then I stormed out.
It was known to me, that the lead developer had actually argued against me being laid off. And that he was upset about it, we made amends, but the fact remains that I was laid off because the owner did not think of me as an asset, regardless of how many times I worked alongside the lead developer or how valuable I was actually to the company, their infrastructure did get better while we worked together, so I just assumed that he never actually did any mention of my value.
I lasted 2 months without a job, feeling horribly shitty because my wife had to work harder to ensure our stability whilst I was without any sort of salary. At this time I had already my degree, so all I had to do was look better. In the meantime I decided to study more about other technologies. I learn React, and got way better at JS and Node that I thought I could and was finally able to get another job as a full stack developer for another company.
I have been here since 2 months. It has been weird, we do classic ASP, which is completely pointless at this time, but meh. At this time though, I just don't really have the same motivation. Its really hard for me to trust the people that I work with and would like to connect with more developers.21 -
My development process seems to go:
1. Write code
2. Believe that said code is amazing
3. Write more code
4. Revisit earlier code and start to doubt it's amazing-ness
5. Get frustrated that it could be done better
6. Redo 1 and repeat cycle
Seems a massive waste of time but I tend to like taking a different approach as soon as I find I'm getting stuck with the previous one.
I then get encouraged to take the quick/easy approach which seems like a backwards step and not worthwhile because I know it won't be as fast/efficient.2 -
Worst collaboration experience story?
I was not directly involved, it was a Delphi -> C# conversion of our customer returns application.
The dev manager was out to prove waterfall was the only development methodology that could make convert the monolith app to a lean, multi-tier, enterprise-worthy application.
Starting out with a team of 7 (3 devs, 2 dbas, team mgr, and the dev department mgr), they spent around 3 months designing, meetings, and more meetings. Armed with 50+ page specification Word document (not counting the countless Visio workflow diagrams and Microsoft Project timeline/ghantt charts), the team was ready to start coding.
The database design, workflow, and UI design (using Visio), was well done/thought out, but problems started on day one.
- Team mgr and Dev mgr split up the 3 devs, 1 dev wrote the database access library tier, 1 wrote the service tier, the other dev wrote the UI (I'll add this was the dev's first experience with WPF).
- Per the specification, all the layers wouldn't be integrated until all of them met the standards (unit tested, free from errors from VS's code analyzer, etc)
- By the time the devs where ready to code, the DBAs were already tasked with other projects, so the Returns app was prioritized to "when we get around to it"
Fast forward 6 months later, all the devs were 'done' coding, having very little/no communication with one another, then the integration. The service and database layers assumed different design patterns and different database relationships and the UI layer required functionality neither layers anticipated (ex. multi-users and the service maintaining some sort of state between them).
Those issues took about a month to work out, then the app began beta testing with real end users. App didn't make it 10 minutes before users gave up. Numerous UI logic errors, runtime errors, and overall app stability. Because the UI was so bad, the dev mgr brought in one of the web developers (she was pretty good at UI design). You might guess how useful someone is being dropped in on complex project , months after-the-fact and being told "Fix it!".
Couple of months of UI re-design and many other changes, the app was ready for beta testing.
In the mean time, the company hired a new customer service manager. When he saw the application, he rejected the app because he re-designed the entire returns process to be more efficient. The application UI was written to the exact step-by-step old returns process with little/no deviation.
With a tremendous amount of push-back (TL;DR), the dev mgr promised to change the app, but only after it was deployed into production (using "we can fix it later" excuse).
Still plagued with numerous bugs, the app was finally deployed. In attempts to save face, there was a company-wide party to celebrate the 'death' of the "old Delphi returns app" and the birth of the new. Cake, drinks, certificates of achievements for the devs, etc.
By the end of the project, the devs hated each other. Finger pointing, petty squabbles, out-right "FU!"s across the cube walls, etc. All the team members were re-assigned to other teams to separate them, leaving a single new hire to fix all the issues.5 -
I miss the good times when the web was lightweight and efficient.
I miss the times when essential website content was immediately delivered as HTML through the first HTTP request.
I miss the times when I could open a twitter URL and have the tweet text appear on screen in two seconds rather than a useless splash screen followed by some loading spinners.
I miss the times when I could open a YouTube watch page and see the title and description on screen in two seconds rather than in ten.
I miss the times when YouTube comments were readily loaded rather than only starting to load when I scroll down.
JavaScript was lightweight and used for its intended purpose, to enhance the experience by loading content at the page bottom and by allowing interaction such as posting comments without having to reload the entire page, for example.
Now pretty much all popular websites are bloated with heavy JavaScript. Your browser needs to walk through millions of bytes of JavaScript code just to show a tweet worth 200 bytes of text.
The watch page of YouTube (known as "polymer", used since 2017) loads more than eight megabytes of JavaScript last time I checked. In 2012, it was one to two hundred kilobytes of HTML and at most a few hundred kilobytes of JavaScript, mostly for the HTML5 player.
And if one little error dares to occur on a JavaScript-based page, you get a blank page of nothingness.
Sure, computers are more powerful than they used to be. But that does not mean we should deliberately make our new software and website slower and more bloated.
"Wirth's law is an adage on computer performance which states that software is getting slower more rapidly than hardware is becoming faster."

Is "++i" more efficient or "i++" ?
P.S. I already wasted more cpu cycles by posting this, than I would ever waste by using either of them....8 -
I don’t like to judge people based on what languages they like (because I like all of them). But I can’t deny the pattern anymore.
Smart people know and enjoy smart languages: Smalltalk, OCaml, Clojure, Lisp, Haskell, etc. They may use JavaScript or PHP to make money, but ask them to code in their smart language and they’ll be more efficient. Getting old, some of those people say “screw it” and find a Haskell job.
You, my friend, are not one of those people. You are VSCode-dwelling goblin who thinks lambda calculus has something to do with JS arrow function notation, is scared of reduce() and not even good at the single fucking language they know.
Insta coders and that mechanical keyboard collector dorks are not “superstars” you got to be like.11 -

Trying not to suck at code.
A good coder seems to be some one who does mistakes quickly and has strategies on how to resolve them even quicker.
The speed at which you create/resolve your problem is the experience curve at which you are learning.
How do you deal with headaches and frustration when spending hours on the same issue?
What are common efficient strat for debugging?
I know this sounds very generalised but i feel like it takes me days to do small things and need to take breaks all the time to relieve the pressure.
Any advice for a rookie?11 -
I hate UI design. When you code functionality, you either make a thing work or crash, efficient or unefficient, reliable or unreliable, maintainable or unmaintainable; but in UI design there's by no means an established way to make something look pretty and that pisses the crap out of me. You cand spend countless hours working in UI design, using the latest CSS libraries and frameworks, but at the end, any client can easily say it's crap no matter how cool anyone else think it looks. UI design sucks.2

Found this gem of a comment in a code base written 4 years back.
/*
Invoke <Service Base URL>/asset/v2/details/<SN> to get asset details
Feeling very bad to include this call, but we really need to use this !!!
This call is gonna take ~20s to respond. I've even increased the overall timeout of this module, just for this call !!!
So, if you are looking to debug any performance issue, I wish you jump directly here,
remove this call and just use master data management (MDM)
P.S: It is not that simple, as MDM and this asset DB (both asset masters) has differences in how the asset is defined :(
*/
Still trying to understand how to remove this costly time-consuming call and replace with an efficient one !!
And, of-course, the original author left 2 years back :(3 -
Today I am gonna start writing code in react to replace/improve an old silverlight project.
I need to show react is faster, easier and more efficient than angular.
Thumbs up if you like react and comment if you think I'm wrong 🙂9 -
Consumers ruined software development and we the developers have little to no chance of changing it.
Recently I read a great blog post by someone called Nikita, the blog post talks mostly about the lack of efficiency and waste of resources modern software has and even tho I agree with the sentiment I don't agree with some things.
First of all the way the author compares software engineering to mechanical, civil and aeroespacial engineering is flawed, why? Because they all directly impact the average consumer more than laggy chrome.
Do you know why car engines have reached such high efficiency numbers? Gas prices keep increasing, why is building a skyscraper better, cheaper and safer than before? Consumers want cheaper and safer buildings, why are airplanes so carefully engineered? Consumers want safer and cheaper flights.
Wanna know what the average software consumer wants? Shiny "beautiful" software that is either dirt ship or free and does what it needs to. The difference between our end product is that average consumers DON'T see the end product, they just experience the light, intuitive experience we are demanded to provide! It's not for nothing that the stereotype of "wizard" still exists, for the average folk magic and electricity makes their devices function and we are to blame, we did our jobs TOO well!
Don't get me wrong, I am about to become a software engineer and efficient, elegant, quality code is the second best eye candy next to a 21yo LA model. BUT dirt cheap software doesn't mean quality software, software developed in a hurry is not quality software and that's what douchebag bosses and consumers demand! They want it cheap, they want it shiny and they wanted it yesterday!
Just look at where the actual effort is going, devs focus on delivering half baked solutions on time just to "harden" the software later and I don't blame them, complete, quality, efficient solutions take time and effort and that costs money, money companies and users don't want to invest most of the time. Who gets to worry about efficiency and ms speed gains? Big ass companies where every second counts because it directly affects their bottom line.
People don't give a shit and it sucks but they forfeit the right to complain the moment they start screaming about the buttons not glaring when hovered upon rather than the 60sec bootup, actual efforts to make quality software are made on people's own time or time critical projects.
You put up a nice example with the python tweet snippet, you have a python script that runs everyday and takes 1.6 seconds, what if I told you I'll pay you 50 cents for you to translate it to Rust and it takes you 6 hours or better what if you do it for free?
The answer to that sort of questions is given every day when "enganeers" across the lake claim to make you an Uber app for 100 bucks in 5 days, people just don't care, we do and that's why developers often end up with the fancy stuff and creating startups from the ground up, they put in the effort and they are compensated for it.
I agree things will get better, things are getting better and we are working to make programs and systems more efficient (specially in the Open Source community or high end Tech companies) but unless consumers and university teachers change their mindset not much can be done about the regular folk.
For now my mother doesn't care if her Android phone takes too much time to turn on as long as it runs Candy Crush just fine. On my part I'll keep programming the best I can, optimizing the best I can for my own projects and others because that's just how I roll, but if I'm hungry I won't hesitate to give you the performance you pay for.

So I left this company I was working for for about 6 years and then eventually came back earlier this year. It was basically 2 backend devs, 2 frontend, and a designer, with me being one of the frontend devs, and the other operating as the owner/alpha of the group. And our coding styles couldn’t have been more different. I wrote code with purpose that could scale, while he wrote garbage that I affectionally labelled "brute force code"; meaning it eventually got the job done, but was always a complete nightmare to work with. Think the windiest piece of shit you’ve ever seen and then times it by 10. Edit the simplest thing at your peril. And if you think you fixed something, all you’ve ever really done is create another 10 problems. And because the code was such shit, it relied on certain things to be broken in order for other things to work. Anyway, you get the drift.
In the beginning we used jQuery and so we just continued to use it throughout the years. But then when I finally left I realized we were operating in a bit of a bubble, where we didn’t really care much to ever try anything else, and mostly because we were arrogant. But eventually my boss started to notice the trend of moving away from jQuery, so he converted everything to vanilla JavaScript. Thing is, he hadn’t learned ES6 yet or any of the other tools that came along with it. And so it was a mess, and I was quite shocked at how many lengths he’d gone to create the full conversion. Granted, it was faster. But overall, still a nightmare to work with, as the files were still thousands of lines long. And when I dug deeper, I realized that he’d started to pluck things out of the DOM manually on-demand. And so it dawned on me: he’d been looking at sites built with React and other dif-engines, and then instead of just using one, he decided to reinvent the wheel. And the funny thing is, he thought it was just a matter of always replacing the entire HTML for whatever was needed. And so he thought what he was doing was somehow clever. And why not? He’s a badass mathematician who created an empire with jQuery. And so he obviously didn’t need input from anyone, and especially not from the shitty devs over there at Facebook. Anyway, while I was gone I learned quite a bit of React, and so it was just comical to me when I came back and saw this. Because it would have been a million times more efficient had he just used the proper tool. In short, he’d re-written the entire codebase for two full years and then ended up with another round of brute-force garbage.
So that’s my story. The lesson is, when you work for someone who’s a dumbass piece of shit, sometimes he’ll be so stupid the only recourse is uncontrollable laughter. I became a digital nomad somewhere in between and fucked off to Asia where I barely worked for 2 years. And I’d definitely recommend the same for anyone else with an asshole boss where the work is unfulfilling. Because it doesn’t matter what your job is when you’re living like a millionaire in Asia working 15 hours a week.4 -
I (don't) like how some people say "If your code needs comments, your code is probably ugly and should be rewritten".
Well, asshats. You have never considered complex calculations/functions or "temporary" workarounds, right?
Sometimes, you have to do it in a not-very-readable way for efficiency. There is no way around that in that case, and comments that either explain the code below or provide alternative, slower code that's commented really help others understand your code.
If I ever work with you and you don't bother commenting your code at all (or rather use slow code because more efficient code doesn't appeal to your "muh code dun need comments" approach), I will hate you.6 -
When code is already working and reversed engineer to compare how efficient the current vs previous code. Now, blames self when prev code is an unorthodox code. ^_^1

Linus Torvalds on C++
“C++ leads to really really bad design choices. You invariably start using
the nice library features of the language like STL and Boost and other total and utter crap, that may help you program, but causes:
- infinite amounts of pain when they don't work (and anybody who tells me
that STL and especially Boost are stable and portable is just so full of BS that it's not even funny)
- inefficient abstracted programming models where two years down the road you notice that some abstraction wasn't very efficient, but now all your code depends on all the nice object models around it, and you cannot fix it without rewriting your app.”

I'm feeling like writing this down...
So today I got told off by my boss. Why? Because my job bores me.
My current title, "webmaster", is quite similar to "plumber" where I work. I fix holes on our websites, and I tell "qualified" people (external providers) how a project should be made. Nothing exciting, nothing creative, boring.
So I got told off today for being "laid-back" in a newsletter project (GDPR, looking at you) and not being thorough in my procedures of testing and configuration. Fair enough, I didn't care and I admitted it. It's a boring drag-and-drop done in literally 5 minutes, there's no added brain-value here. Plus I got told off by my IT Manager because our Exchange server would not let me receive test emails. Still doesn't work after a day. Yay.
Then she said "we're doing exciting things here, it's not always the case anywhere else you'd work". And I'm like: "really? I love writing code, seeing things coming alive, investigating why things don't run smoothly, writing efficient code (both in performance and in readability)". I hear many friend devs telling me they're doing that and what they do during their "dev-day"... All I'm doing here is "maintenance" (a.k.a boring) stuff that apparently is "exciting". Adding a <script> to handle google tag manager is hell fun, going through compiled CSS and change color values is also thrilling, finding out if a PDF handler application can handle PDF files, re-plugging a computer monitor to make it work...
I think she meant that I'm not at my place here.
Didn't want to tell her that I have no motivation in doing things I don't enjoy making, i.e, my job.
Good thing I have an interview in two weeks2 -
So, it's 22:40 here and I'm sat on a bench staring out at a pond because my stress and anxiety is at an all time high after a couple of weeks of hellish arguments with work and my personal life so as were all developers here to some degree let me convey my fucking thoughts here.
If you care more about maintaining your fucking superiority complex over writing good clean efficient code then get the fuck out of the industry.
I don't give two fucks whether you use Linux or Windows. I couldn't give two fucks about whether you use sublime, Emacs or VIM. I couldn't give two fucks about the framework you spend more time defending than coding in, because absolutely none of it matters if you code like a retard on bath salts you pretentious cunts.
Stop feeding you fucking ego. Absolute cluster fuck of an industry.4 -
Development world is always changing and evolving... It changes before you know it...
So, having the ability to quickly adapt and learn is a must for any Developer... And, this is the one thing that I am sure that everyone knows about or heard about..
But, my advice is quite simple:
"Don't rush into participating in a race, just because everyone else is doing so.
The trick is not to move quickly.. But, to move one step at a time, at the pace in which you are at your most comfortable...
It might seem counterintuitive and a contradiction to what I have said earlier.. But, I hope that by the end of this rant, you will be able to understand my perspective..
This advice is especially useful for people still finding and searching for their place in our world..
Charles Darwin, very wisely understood the philosophy behind 'Survival of the Fittest'..
By 'fittest', he didn't refer to the ones considered to be the strongest or having the most intelligence, but the ones that had mastered the ability to adapt to changing circumstances..
Adaptability is important, but not at the cost of understanding and learning about the fundamental pillars on which this world stands..
Don't rush because when you run, your visions starts to become more narrow.. In your pursuit to reach your goal, you lose the ability to look at the macro details surrounding your goal..
Learning new technology is important, but that doesn't mean that you don't learn about various approaches or how to design a more logical or efficient solution...
Refactoring the code, developing good Testing procedures, learning to interact with your fellow developers are as crucial as learning about the changing trends...
Even, in this ever-changing world, understand that some things will always remain the same, like the adrenaline that course through your veins when you finally solve a long-standing problem...
Curiosity, Discovery and Exploration are the key pillars and hence, when we rush in, we might stop exploring and lose curiosity to discover new and exciting ways to reach our goal..
Or, we might also end up losing the drive that grips us and motivates to continue moving forward inspite of the challenges standing between us and our destination..
And, believe me, once you lose this quality, you might still succeed but the contentment and the satisfaction that you feel will be lost..
And, then, you will remain a developer only through your designation... And, that in my personal opinion, the worst punishment.3 -
Sometimes, rewriting a project can be faster, more time efficient and better to read than trying to fix the single inefficiencies in parts of the code.

I worked with a developer for months. He was senior to me; on more money than me and had way more experience. I spent at least 25% of my time explaining the most basic stuff to him. Things like 'no, that's not how a cache works', 'no, you shouldnt be doing string concatenation inside a loop', 'no you've completely written the wrong thing because you didn't listen'
When he left, he claimed to have finished off a feature for our application. We dove into it, rewrote it, made it more efficient, the code cleaner, the documentation more succinct and the logic more obvious. When I say we, I mean me and a student, and by me and a student, I mean the student with some very light prodding from me.4 -
adding feature and came across some code that looks quite efficient.
really wanted to tell the guy that he did a great job. checks revision history, and the author was me, 2 days ago...2 -
This will definitely trigger many but the truth regardless of how you feel is the greatest programmers are those who understand both the hardware level and software .. only then are you more than a dev or programmer.. you are an engineer...
I challenge the devs who dis believe to go out and learn to build circuits, write optimized, efficient bare metal code.: no sdk.. no api... no drivers ..remove the unneeded abstraction layers that have blinded you...build it yourself, expand your potential and understanding..
Not only will you become more valuable overall, but you will write better code as you are more conscious of performance and space and physics of the physical layer.
I’m not talking about Arduino or raspie
Those who stand strong that high level abstraction languages and use of third party apis is a sufficient sustainable platform of development are blind to reality.. the more people who only know those levels, the less people pushing the industry of the low level.., which is the foundation of everything in the industry.. without that low level software the high level abstractions and systems cannot run
Why did we have huge technology advancements from 70s to early 2000s.... because more people in our industry understood the hardware layer..: wrote the software at the less abstracted layers..
Yeah it takes longer todo things at that low level abstraction.. but good robust products that change the world and industry don’t take a few week or months to build.....
Take this with what you will... I’m just trying to open the eyes of the blind developers to the true nature and reality of our industry23 -
Spent the last month creating a really scalable chat application, with fast front end, all kinds of neat functions such as polls, and a really efficient database structure in Apache Cassandra.. Everything is built to use NoSQL, and even the front-end is using all kinds of features to speed up itself... Now, guess what... The company I'm doing an internship decided that everything needs to be done in MariaDB, and I can basically remove 1/3 of my program, event the front end will get a huge purge of code, and as much as I explained that MariaDB IS NOT FUCKING USABLE FOR A CHAT APPLICATION, and when there are many messages, the access times will get realllllyyy sloow, and that the whole structure there currently is based on NoSQL... Now I can remove all the clustering, custom data types, and bucketing of messages... And store FUCKING JSON IN 'TEXT' FIELDS IN A STUPID SQL DATABASE. FUCK ME6

I think I've been doing too much Android programming in the last three days.
Had a lucid dream last night where I couldn't wake up until I figured out how to set up an inter-thread latch that would allow me to process through a shit ton of data points in parallel without duplication or skipping errors in the most efficient manner (effectively no blocking). We're talking several hundred lines of code. Slept 14 hours last night, I heard my alarm but didn't wake up. When I finally got up, I did what I did in my dream and it worked better than the existing code.
Turns out my brain is great at Java evaluation now, I guess.4 -
Yesterday, i had to use neovim for a task on my friend's laptop. There was no WiFi and I couldn't install Emacs. This guy uses Vim a lot. He recently moved to neovim from vim. He had some Ruby codes going. I had to debug some codes(performance issues). I was reluctant to work on it but i had to. After looking at some keybindings and the plugins that guy had written, using vim was pleasure. It was fast. I could shoot up multiple terminals work on that and was instant. I wrote some plugins to indent my code which worked as it's supposed to. I used spacemacs(as it's configured properly) Emacs but there is some load time on spacemacs and there are some issues shooting up multiple spacemacs on terminals. I had just configured and started using prelude which is beautiful Emacs configuration and is fast.
After using neovim that day something hit me that i had blindly had faith in Emacs without using Vim and i use Emacs only for text editing task and terminal. I don't use it for listening music, browser and other task i can always use modern browsers and Spotify for that. Modern browsers and music players are amazing and using those in Emacs there is always a lack of functionality and UI.(modern people don't use those i think and some Emacs users i know use stripped down version of Emacs i.e. microemacs or XEmacs.
I know vi is present by default on every Linux distribution. That keybindings are same as vim and it can be configured so, it is useful for embedded devices and system architecture. I love terminals and love working on tty. That's why i guess i felt instantly tempted to keep on using vim and i loved it's performance. I checked on evil layer before but there are some issues with evil layer in Emacs like it isn't too efficient like vim. I love lisp though and clojure can be edited nicely in Vim.
Is this sin against the church of Emacs? Should i join vi vi vi? I have already dedicated my life on Emacs (check my bio). Am i tempted by the devil?4 -
When you're really fuckin proud of that extremely clean, elegant, efficient 30 lines of code. It might not be important, but holy shit it's pretty!!3

How do you debate the "it's more complex in my opinion" statement?
So, some months ago I was looking at some code which has stuff as 300 lines of code function(s) and I could feel the bad smell irl...
I analyze it a bit and there is a lot of stuff which is misplaced, repeated or unsafe.
I first re-arrange it and remove redundancy, then break it down in about five functions (plus a caller), all is now readable and assignIcon k(made-up name) only assigns an icon, it doesn't also send a rocket in space.
But then I put the code in review and the previous author of the code says that it's now unreadable, because s/he has to look as multiple functions. I counter by showing how s/he does not need to read 300 lines of code to find a bug, but approximately 60, and I point at how misleading having an `assignIcon` function which also sends rockets in space is.
The counter? "But it looks confusing to have smaller functions, revert it."
How would you debate that? I am shy and hate myself a lot, so I have issues debating good points, but I am really really sure a lot of bugs I encountered were due to stuff like this so I would like to be able to explain my point in a more efficient way, for future teams.12 -
Hypothetical Question:
Write a complex code to make it efficient Or
Write a simple code so that the next developer who works on it understands the code easily.10 -

Just go to GPT and get me the code today!!!
Like wtf why does every non-tech guy thinks GPT is the solution for each problem.
So, a workmate wanted a fullstack system ready in 2 days and argues that its too easy with GPT. I mean yeah GPT helps, sometimes, on frequent rare occasions. But, that can't be the solution to everything, like ask it to setup the whole backend frontend integration, will it? ask it to manage assets will it? ask it to write complex code, it fails, miserably, okay like me but that's the point. Just because random transformers pop up each week containing some random shitty weights (not always agreed) that can't replace a full stack developer. These 'attention' seeking models are as good as another tool, a bit efficient, but at the end of the day its just a tool, all it does is lessen the typing time but gives more errors too. The average time remains the same. And my non-tech manager can't understand he can't do it himself earlier using GPT. Succkkkkkkssss!5 -
Is your code green?
I've been thinking a lot about this for the past year. There was recently an article on this on slashdot.
I like optimising things to a reasonable degree and avoid bloat. What are some signs of code that isn't green?
* Use of technology that says its fast without real expert review and measurement. Lots of tech out their claims to be fast but actually isn't or is doing so by saturation resources while being inefficient.
* It uses caching. Many might find that counter intuitive. In technology it is surprisingly common to see people scale or cache rather than directly fixing the thing that's watt expensive which is compounded when the cache has weak coverage.
* It uses scaling. Originally scaling was a last resort. The reason is simple, it introduces excessive complexity. Today it's common to see people scale things rather than make them efficient. You end up needing ten instances when a bit of skill could bring you down to one which could scale as well but likely wont need to.
* It uses a non-trivial framework. Frameworks are rarely fast. Most will fall in the range of ten to a thousand times slower in terms of CPU usage. Memory bloat may also force the need for more instances. Frameworks written on already slow high level languages may be especially bad.
* Lacks optimisations for obvious bottlenecks.
* It runs slowly.
* It lacks even basic resource usage measurement.
Unfortunately smells are not enough on their own but are a start. Real measurement and expert review is always the only way to get an idea of if your code is reasonably green.
I find it not uncommon to see things require tens to hundreds to thousands of resources than needed if not more.
In terms of cycles that can be the difference between needing a single core and a thousand cores.
This is common in the industry but it's not because people didn't write everything in assembly. It's usually leaning toward the extreme opposite.
Optimisations are often easy and don't require writing code in binary. In fact the resulting code is often simpler. Excess complexity and inefficient code tend to go hand in hand. Sometimes a code cleaning service is all you need to enhance your green.
I once rewrote a data parsing library that had to parse a hundred MB and was a performance hotspot into C from an interpreted language. I measured it and the results were good. It had been optimised as much as possible in the interpreted version but way still 50 times faster minimum in C.
I recently stumbled upon someone's attempt to do the same and I was able to optimise the interpreted version in five minutes to be twice as fast as the C++ version.
I see opportunity to optimise everywhere in software. A billion KG CO2 could be saved easy if a few green code shops popped up. It's also often a net win. Faster software, lower costs, lower management burden... I'm thinking of starting a consultancy.
The problem is after witnessing the likes of Greta Thunberg then if that's what the next generation has in store then as far as I'm concerned the world can fucking burn and her generation along with it.6 -
Usually my workplace is pretty chill, but today something rantworthy happened!
During code review, I found this guy had styled each element inside his components using nth-child selectors. For instance, in a card the heading was styled by nth-child(1), the text was styled by nth-child(2) and so on... No use of actual fucking classnames.
When I pointed this out, he told me it was actually the better way of doing things because classnames increase the size of the HTML document!
He also claimed proudly that nth-child() is more efficient in performance (idk - anybody can confirm this?)
I'm the only "css guy" there so nobody could second my views. Posting it here so that I can show this to him tomorrow by demonstrating what opinion other css devs have on this and prove my concerns / convince him to change his code.7 -
We had 1 Android app to be developed for charity org for data collection for ground water level increase competition among villages.
Initial scope was very small & feasible. Around 10 forms with 3-4 fields in each to be developed in 2 months (1 for dev, 1 for testing). There was a prod version which had similar forms with no validations etc.
We had received prod source, which was total junk. No KT was given.
In existing source, spelling mistakes were there in the era of spell/grammar checking tools.
There were rural names of classes, variables in regional language in English letters & that regional language is somewhat known to some developers but even they don't know those rural names' meanings. This costed us at great length in visualizing data flow between entities. Even Google translate wasn't reliable for this language due to low Internet penetration in that language region.
OOP wasn't followed, so at 10 places exact same code exists. If error or bug needed to be fixed it had to be fixed at all those 10 places.
No foreign key relationships was there in database while actually there were logical relations among different entites.
No created, updated timestamps in records at app side to have audit trail.
Small part of that existing source was quite good with Fragments, MVP etc. while other part was ancient Activities with business logic.
We have to support Android 4.0 to 9.0 of many screen sizes & resolutions without any target devices issued to us by the client.
Then Corona lockdown happened & during that suddenly client side professionals became over efficient.
Client started adding requirements like very complex validation which has inter-entity dependencies. Then they started filing bugs from prod version on us.
Let's come to the developers' expertise,
2 developers with 8+ years of experience & they're not knowing how to resolve conflicts in git merge which were created by them only due to not following git best practice for coding like only appending new implementation in existing classes for easy auto merge etc.
They are thinking like handling click events is called development.
They don't want to think about OOP, well structured code. They don't want to re-use code mostly & when they copy paste, they think it's called re-use.
They wanted to follow old school Java development in memory scarce Android app life cycle in end user phone. They don't understand memory leaks, even though it's pin pointed by memory leak detection tools (Leak canary etc.).
Now 3.5 months are over, that competition was called off for this year due to Corona & development is still ongoing.
We are nowhere close to completion even for initial internal QA round.
On top of this, nothing is billable so it's like financial suicide.
Remember whatever said here is only 10% of what is faced.

There’s a guy at work I hate so much. He doesn’t know when a problem shouldn’t exist, he never checks to see if there is a better more maintainable and efficient way to solve a problem, lacks attention to detail, has the attention span of a goldfish, writes shitty overly complicated code, fuuuck
If you talked to this guy in person, you’d think he’s a genius who has it all figured out, but he’s just a professional bullshitter14 -

Back when I was still in school for comp sci we had an advanced software engineering and design class with c++. At this time, everyone was expected to be proficient enough with cpp to go ahead and properly work with whatever the instructor would throw at us. And pretty much everyone was since past classes included a lot of c++ development. Of course, efficient at least related to academic studies rather than actual real world development.
Our teacher would mix in a lot pf phyisics and mathematics into what we were doing, something that I greatly enjoyed, while at the same time putting real world value concerning cpp best practices to avoid common pitfalls in the development of said language. Since most bugs seemed to be memory based he would be particularly strict about that.
One classmate, good friend and an actual proper developer now a days would ALWAYS forget to free his resources...ALWAYS for whatever fucking reason he would just ignore that shit, regardless of how much the instructor would make a point on it.
At one point during class on a virtual lecture the dude literally addressed a couple of students but when he got to my boy in particular he said: "you are the reason why people are praying to Mozilla and Hoare to release Rust as fast as possible into a suitable alternative to high performant code in C++, WHY won't you pay attention to how you deal with memory management?"
And it stuck with me. I merely a recreational cpp dev, most of my profesional work is done on web development, so I cannot attest to all the additional unsafe code that people encounter in the wild when dealing with cpp on a professional level.
But in terms of them common criticisms of C and C++ for which memory is so important to work with, wouldn't you guys say that it comes more from the side of people just not knowing what they are doing rather than a fault on the language itself?
I see the merits and beauty of Rust, I truly do, it is a fantastic language, with a standardized build system and a lot of good design put into it. But I can't really fathom it being the cpp killer, if anything, the real cpp killers are bad devs that just don't know what they are doing or miss shit.

// example.json
{ "hasCustomerAgreedToTermsAndConditions": no }
Slightly irritated by my IDEs warning, I squinted back at my code. It took me a second too long to spot my mistake. First, I was baffeld at my own incompetence. Then I grew defensive about it. "Why not?!" I thought. "Less typing, so efficient, so much time saved, so wow!"
I realized at that moment, that it was probably best to call it a day and go to bed.
And so I did.3 -
AI is never going to write code efficient like Humans do.
The whole AI, neural network bullshit is overrated.
Training a Network to recognize Images or playing Super Mario is far away from writing code.4 -
So true ...
"Many developers on a schedule aren't making efforts to write clean and efficient code, relying on idiot-proof languages (and consequently more RAM and faster processors) to make up for their malaise."2 -
Can anyone tell me how to become less resentful and less bitter? I am becoming a miserable fuck. Its true that I burned out in this job after doing 100hrs overtime during previous month, its also true that I am pissed off about having to wait 8-9 weeks for my raise to happen. I cared so much that I burned out and now Im trying to set some boundaries but damage was done and Im struggling dealing with it.
I took 6 days off to disconnect from work (still was responding to some major blockers and monitoring stuff). Today I got back at work and interacting with two incompetent devs immediately sets me off. Imagine taking 2-3 days and extra meetings to do a simple fix which shouldnt take longer than 30min. My mind was blown and still gets constantly blown about how ineffective some members of team are.
I am becaming a ranting fuck. I even noticed one person escaping my rants once he sees that they are taking longer than 5min.
Right now I started setting boundaries - I clock my 8 hours, disable slack/email notifications and get the fuck out from the office. I dont care if I will have to sit in traffic extra 30min during summer heat, Im done with putting in overtime and caring so much about being efficient. I will just start working on my side project and put my love/learnings in that. Hoping that by the end of year I will have couple projects to show in my portfolio so I could find a better paying job...
In the past I was the sole dev responsible for apps and I was communicating with ceos/ctos/product owners/designers directly. This is my first position where I work in a dev team and boy oh boy out of 8 devs barely 3 are competent enough but their output is how to say... Not the biggest. Anyways...
Transition to boundaries and 'normal life' is so hard. Nobody told me that I will have to learn to work with and tolerate such retarded and incompetent people. Im talking about illiterate monkeys who cant even read or write. Im amazed how they manage to code.8 -
I hope I'm not alone getting the warm fuzzy feeling you get when you write some code that is beautiful. I know beautiful is a strange choice of words but I find the efficient simplicity of good code to be beautiful!
-
You know what bugs me the most? When people make their code fast and efficient, but not updatable. Like if I want to add something for my program to look for I'd rather just put another item in an array than modify/add 30 lines. Jesus Christ people.1
-
So happy about being about to convince management that we needed a large refactor, due to requirements change, and since the code architecture from the beginning had boundaries built before knowing all the requirements...
pulled the shame on us, this is a learning lesson card.. blah blah blah
Also explained we need to implement an RTOS, and make the system event driven... which then a stupid programmer said you mean interrupt driven ... and management lost their minds... ( bad memories of poorly executed interrupts in the past).... had to bring everyone back down to earth.. explained yes it’s interrupt driven, but interrupt driven properly unlike in the past (prior to me)... the fuck didn’t properly prioritize the interrupts and did WAYYY too much in the interrupts.
Explained we will be implementing interrupts along side DMA, and literally no message could be lost in normal execution.. and explained polling the old way along side no RTOS, Wastes power, CPU resources and throws timing off.
Same fucker spoke up and said how the fuck You supposed to do timing, all the timing will be further off... I said wrong, in this system .. unlike yours, this is discreet timing potential and accurate as fuck... unlike your round robin while loop of death.
Anyway they gave me 3 weeks.. and the system out performs, and is more power efficient than the older model.
The interrupting developer, now gives me way more respect...4 -
Coding was and is the thing that currently feeds me the most efficient way. But it's also what caused to cringe and to hate people the most because of legacy code and immensely narrowminded dimwits aka clients.
But yeah: Coding is love, coding is life. ❤️ -

A day in the life of a paypal dev.
1. Slurp some starbucks
2. Do a lil' Meeting
3. Eat lunch
4. 1on1 Meeting with manager for one hour
5. Scroll over some code and look at the beautiful Momentum ToDo app
6. Bid some employee farewell (seems to happen every day there apparently)
Sounds pretty efficient. When you write no code you cannot create any bugs...3 -
I don't want to use Visual Basic!
I'm a 17 year old boy and I have a couple of years of experience with coding. At school we had to choose between a couple of things to do 2 hours every week. One of them was about computers and programming. Sounds fun, right?
The teacher is letting us code in Visual Basic in MS Excel. I tried to explain him that I know how to code, but he still wants me to listen to him.
He doesn't even use any indentation! I can't look at it and I don't want to use VB it sucks just let me use js or anything else but not VB! Why won't you just accept I'm 10 times better than you! Just let me do my thing!
Now he thinks he can challenge me with a password strength checker. I want to use js, some regex to make it very short and efficient and a nicely styled web page. But now I'll be forced to use a horrible programming language (VB) I never used before!24 -
Node: The most passive aggressive language I've had the displeasure of programming in.
Reference an undefined variable in a module? Prepare to waste your time hunting for it, because the runtime won't tell you about it until you reference a property or method on the quietly undefined module object.
Think you know how promises work? As a hiring manager, I've found that less than 5% of otherwise well-experienced devs are out of the Dunning Kruger danger zone.
Async causes edge cases and extra dev effort that add to the effort required to make a quality product.
Got a bug in one of your modules? Prepare yourself for some downtime because a single misplaced parentheses can take out the entire Node process, killing unrelated pages and even static file hosting.
All this makes for a programming experience that demands much higher cognitive load, creates more categories of bugs, and leads to code bloat/smell much more quickly than other commonly substituted languages.
From a business perspective, the money you save on scaling (assuming your app is more compute efficient under Node) is wasted on salaries and opportunity costs stemming from longer dev time, more QA, and more frequent outages.
IMO, Node is an awesome experiment, a fun language, a great tool for specific use cases, and a terrible fucking choice for an entire website.8 -
At what point can I claim to not be a script kiddie anymore?
Like, I've built compilers, and interpreters for an excel-like syntax, I refactored a pdf-parsing library from the ground up. I managed databases and wrote protocols for communicating with hardware.
But most of my experience is with python / nodejs / golang. It is only recently that I started playing with C and rust for actual efficient system code.8 -
The worst part of being a dev? Working in teams.
And I don't mean that in the "I'm the best ninja code wizard in the whole world and you're all holding me back" kinda way. I'm thinking more in the lines of someone who has to deal with that kind of attitude on a daily basis. As someone who recently was put in a leading position in a dev team, this is by far one of the worst experiences that came with it.
Some examples?
- One dev completely changed the naming scheme for variables in a class he worked on for one. single. bug fix. His reason? He just didn't like it!
- Another one noticed that data he was supplied with was not in the specified format. Instead of flagging this with the project leads, he just rewrote his parser to fit the data. A couple of weeks later the supplier noticed the error, fixed the format and suddenly everyone wondered why the software failed processing the data.
- Or that one senior dev, that just refuses to accept changes because "it was always done like this and it worked" No, it didn't. That's why it was changed!
Once a dev team reaches a certain size, people need to realize that stuff like coding rules and process guidelines are not there to annoy them but to help the whole team work as efficient as possible. I don't care how good a programmer you are, if you can't check your ego you don't belong in any kind of team-oriented development project! -
What's the longest project you've worked on (in a passage of time type measurement)?. Mine' s a client website, 2 years (so far) in the making. 1 complete redesign, and re-written vast chunks of CSS and code because some of it was shit (2 yrs ago). Now it's super efficient and looking good. Still not finished though. Fortunately they know it's their fault and they have paid up to date, we are at double the original estimate now. I have not moaned at them because they have not moaned at my charges.2

Just a quick rant on JavaScript,
So there’s a lot of people hating javascript, and while not a long time ago i was part of them, but I changed my opinion a little.
I think JavaScript is a great way to deal with website programming as it is quick and efficient, but I would not say to program directly on it, use a js-compilable language (CoffeScript, TypeScript, Kotlin(I think), etc.), but then you might say: “Well, no need for js then, compile it in byte code”. That would break the point of how I see web design/dev. The main intent behind webpages is to have an easy and fast way to send code to other computers to render them, that’s why it is interpreted: “Easy to send” and “*All* computers can handle it” with the proper browser. You need to be able to change the way the website is rendered and/or works sometimes, for diverse reasons like copy/pasting data, make it render properly or use plugins/add-ons to change that code to suit your needs.
I think js should be kept as a “readable byte-code”, so that means: {
Keep comments when compiling the js-compilable code,
Add standardized machine-readable comments that will indicate to smart code viewers how to show a particular thing (Like have a higher-end function compiled in js shown as a minimized code with explanations of the function)
Keep it nicely formated and don’t obfuscate (coz that’s annoying)
Etc.
}
So you bypass the quirks and all that pesky js stuff, while keeping it’s good sides.

Part 2:
Web design for non-web:
Ok so things like node.js, electron, react-native and all that stuff; I won’t say they’re bad but...
Why we have this is because web designers wanted to make desktop apps and were like “Hey! Making web pages is easy! Let’s port it to desktop”, the problem is: Web technologies were made to work on a restricted canvas, aka a browser. It’s good on web for reasons mention earlier and more. But it’s not on desktop! You’re trying to push it outside of those boundaries. It’s difficult to make it break that canvas and go outside, make something that really works! For social media clients and that kind of stuff that you want to make a little more inclusive, yes! it’s a great idea (hello devrantron ;), but not if it’s an exact same copy of the website, just use the website. But for things that are supposed to really make use of YOUR computer; no!
I see those PWA (progressive webapps aka mobile app, but it’s an offline website”), I stand for the same positions, social media and those sort of things: yes, great idea! Games? 🤢.
I have way more to say but I have difficulties to remember them while reading, so feel free to comment your thoughts
Lol, “just a quick rant”1 -
If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:
This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...
Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?
Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...
All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).
So what other options are there for making plugins in Go?
There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...
Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...
Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.
Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.
As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...
Have a good night(/day)!13 -

I always had this mentality that I shouldn’t rely on a certain library or framework for my entire project because what if one day they stop supporting it. (Yeah I’m talking to u vuetify) That’s why I came up with this code structure that for everything that I wanna do I have a ‘driver’ library all coded by myself that interacts with that third party framework or library so if they stop supporting it I could just change a couple of lines of code in my driver file and my codebase should be working again. But I feel like this ‘driver’ approach is not the most efficient way of going in terms of memory usage. Do you guys think I should keep it simple and directly use those libraries or this is actually not a bad approach.6

How do you explain to your client that no, you cannot have a perfect solution, because the algorithm is O(2^n)?
I mean, without requiring him to get a degree in CS. Also without making him think that you can't build efficient code because you're dumb. Or that the hardware is slow.3 -
I really miss having a team. Don't get me wrong, right now I do what I love and I got into a position where I can actually do Quality Assurance instead of just testing and I enjoy being able to actually change things instead of just repeating what problems there are and acting surprised when the same processes produce the same bugs over and over again but I really hope that we'll interview anything else than mouthbreathers soon.
I'm aware of the fact that QA isn't sexy and that few people who could become "Software ninja Rockstars" choose to go into it but can it be that hard to find at least two or three people who can write and read code at least on a junior level and understand how web protocols work? I get the feeling my entire branch is nothing but shit talkers clicking around blindly on pages.
I just want to exchange ideas again, come up with innovative tools, tweaking processes, learning from and teaching each other while we watch the entire operation get more and more efficient.1 -

Ban visual programming programs, like scratch after the fist month introduce them to enhanced Google search strings and let them code on the command line going from imperative, over functional to object oriented programming styles using languages suited for the current style. Not like using Java from the get go. I hated it, waiting until everyone got to the point where they kind of understood the logic but failed at using correct syntax and efficient coding styles.

My boss is being a stupid cunt. To give you a background we were facing issues with our Collections system. First week December 2019, I and a colleague of mine came up with a new efficient collections architecture. My colleague and I started to Code and create automation scripts mid December and completed it in First week of Jan 2020. This PoC version was supposed to be just between the Dev team(App Dev and Back end, also one from the Ops side to verify the data). I did not receive any feedback on the actual collections system and the data integrity but during this time all they’ve done is take meetings with no real outcome. I raised this and the only email I got is data is looking fine when I know it is not.Now in First week of Feb, he is stressing us to go ahead and deploy the architecture in Production and we have not done any Code Review, Static Code analysis, any real tests on Code and deployment scripts. Have not discussed any metrics for our dashboard and alerting. I have no idea how to handle this cunt. I have even asked for resources to atleast productionalize the code and move ahead the deployment and still no out come. I’ll go in a meeting with him in an hour, I will be very blunt and tell him that whatever he is doing is a foolish way and maybe resign in couple of weeks6

Just had my reasoning for not doing technical projects for interviews proven.
Pass the first 2 stages of interview (including showing some personal portfolio projects) then after a week of hearing nothing get sent a technical project to complete.
Spend every spare moment for a week polishing this thing, decent front end, quick and efficient back end, low traffic between fe, be, persistence etc.
Submit the code at midday ready for the interview the following day, only for the company to phone at 5pm and say all is fine and the code is great for the final interview (walkthrough) the next day, then phone 5:10pm phone and pull the position.
That company has just had free work done which should have cost 1 weeks worth of fees, using the premise of a job at the end of it, only to take the code that they are super happy with and run with no payout.10 -

Just had a very productive night with @hahaha1234 and @jappe. Revisited a lot of code, made it simpler, faster, storage efficient and future proof. Our smart search engine is getting somewhere now. Tomorow we will be continue building ofcourse, but first: time to sleep! It is 3:45AM and after that, go running on the beach in Zandvoort.1 -
So we're doing this contract work for this other company and the project is just an overcomplicated piece of garbage where they shoved every buzzword technology into it just because. I managed to get the code just about organized and functional on our side of the contract and it was looking up when suddenly the management decides "we had a rough start, lets start over, learning from our mistakes"
So I was thinking "cool, there were a lot of problems with this overcomplicated pre-optimized stack, surely we can only do better".. oh boy how naive I was. See Im not the guy in charge of the infrastructure (unfortunately) and really the project structure across this huge multi service project is a free-for-all kind of management.. so we had a call on friday where they explained how the new structure should be built... 3 new technologies, more micro services and even worse dependency tree later I was contemplating suicide on the spot.
I tried to make this shit usable and efficient and all my fucking work went down the drain in a single day of these fuckers throwing more buzzwords at the problem... I can't even get a new empty project started without browsing our huge 100+ repo project git for which dependency Im still missing to even run it...
I fucking hate this retarded piece of crap project and I hope every "manager" and "developer" with an exception of very few chokes on a cock...2 -
I freaking hate slow IDEs, especially ones made in Java.
I used to use an IDE/text editor called geany, and it was great, you could do almost every language in it and it worked great. It was fast, and efficient, it was a no-nonsense editor. That was when I was a kid, but I got in univ and got a job, so I had to start using big boy """""enterprise""""" IDEs like eclipse.
Eclipse, netbeans, and intellij (basically every Java based IDE except BlueJ) are exactly what is wrong with IDEs. They are clunky editors that frankly would be better off gone. They are slow, eat RAM like crazy (like most Java software). You just CANNOT have eclipse open for extended periods of time, because it WILL take up too much resources and get slow as heck. Android Studio (based on intellij) is a nightmare to work with. It just does not want to cooperate with you (I will agree they have improved a lot though).
I cannot believe I am saying this, but even the electron based IDEs like atom and code-oss are better than them. They are very easily expandable, something that Java was supposed to be, but is not. They have tons of plugins. Even if its not there, you can make one without having to spend a lifetime making the plugin! They look good. I never thought that going from IDEs with """""enterprise""""" UIs to something modern like code-oss would feel this great. Its ridiculous, I don't want to create a darn project for every single file that I want to edit, I just want syntax highlighting for a single .sh file that I want to edit right now. A project is just a way to logically define what is one "unit" or a "container for multiple files", you know what else is that? A simple directory.
Also I don't want 9 billion .xml files for the IDE to store its crap. Just make a .vscode like folder to hide your shit.11 -
I had the idea that part of the problem of NN and ML research is we all use the same standard loss and nonlinear functions. In theory most NN architectures are universal aproximators. But theres a big gap between symbolic and numeric computation.
But some of our bigger leaps in improvement weren't just from new architectures, but entire new approaches to how data is transformed, and how we calculate loss, for example KL divergence.
And it occured to me all we really need is training/test/validation data and with the right approach we can let the system discover the architecture (been done before), but also the nonlinear and loss functions itself, and see what pops out the other side as a result.
If a network can instrument its own code as it were, maybe it'd find new and useful nonlinear functions and losses. Networks wouldn't just specificy a conv layer here, or a maxpool there, but derive implementations of these all on their own.
More importantly with a little pruning, we could even use successful examples for bootstrapping smaller more efficient algorithms, all within the graph itself, and use genetic algorithms to mix and match nodes at training time to discover what works or doesn't, or do training, testing, and validation in batches, to anneal a network in the correct direction.
By generating variations of successful nodes and graphs, and using substitution, we can use comparison to minimize error (for some measure of error over accuracy and precision), and select the best graph variations, without strictly having to do much point mutation within any given node, minimizing deleterious effects, sort of like how gene expression leads to unexpected but fitness-improving results for an entire organism, while point-mutations typically cause disease.
It might seem like this wouldn't work out the gate, just on the basis of intuition, but I think the benefit of working through node substitutions or entire subgraph substitution, is that we can check test/validation loss before training is even complete.
If we train a network to specify a known loss, we can even have that evaluate the networks themselves, and run variations on our network loss node to find better losses during training time, and at some point let nodes refer to these same loss calculation graphs, within themselves, switching between them dynamically..via variation and substitution.
I could even invision probabilistic lists of jump addresses, or mappings of value ranges to jump addresses, or having await() style opcodes on some nodes that upon being encountered, queue-up ticks from upstream nodes whose calculations the await()ed node relies on, to do things like emergent convolution.
I've written all the classes and started on the interpreter itself, just a few things that need fleshed out now.
Heres my shitty little partial sketch of the opcodes and ideas.

I can proudly say that I understood absolutely nothing; CS stands for cocksucker or rather abysmal failure at the most basic forms of communication, I don't just sit here all day expecting you to flawlessly prove my point with every swallow of breath you draw, yet here we are.
Perhaps one factor involved in producing the generalized cluelessness of my colleagues, I mean their "imposter s*ndrome", has a bit to do with how fucking thick you've formulated this glorified bollocks you call theory. Were not for your incompetence, arcane crackheads like me would simply __not__ be capable of rising to the top of this field entirely via determination and a big salami, therefore I owe you both a debt of gratitude as well as every last word and sign of total disrespect.
As interesting as the study of computational complexity can be, if done correctly that is, you idiots are stuck in a mathematician's abstract mindset in a field entirely devoted to application of ideas rather than *just* the ideas themselves.
To answer my own question, it means there's no known efficient solution. That's it. The part about nondeterministic polynomial convolution of an irreductible rectosigmoid junction can apparently be skipped altogether. Anyway, I solved the problem with the computational equivalent of pizza sticks while you were out in the field mentally jacking off to λ.
Lecture is over, now go clean up the ethereal masturbatory residue if you will, I have mystical el Khwarizmi type-shit to solve via further clubbing of abstraction through liverwurst bologna of immense proportions. ^D3 -
So I promised a post after work last night, discussing the new factorization technique.
As before, I use a method called decon() that takes any number, like 697 for example, and first breaks it down into the respective digits and magnitudes.
697 becomes -> 600, 90, and 7.
It then factors *those* to give a decomposition matrix that looks something like the following when printed out:
offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]
offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]
offset: 1, exp: [[Decimal('7'), Decimal('1')]]
Each entry is a pair of numbers representing a prime base and an exponent.
Now the idea was that, in theory, at each magnitude of a product, we could actually search through the *range* of the product of these exponents.
So for offset three (600) here, we're looking at
2^3 * 3 ^ 1 * 5 ^ 2.
But actually we're searching
2^3 * 3 ^ 1 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
2^3 * 3 ^ 1 * 5 ^ 0
2^3 * 3 ^ 0 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
etc..
On the basis that whatever it generates may be the digits of another magnitude in one of our target product's factors.
And the first optimization or filter we can apply is to notice that assuming our factors pq=n,
and where p <= q, it will always be more efficient to search for the digits of p (because its under n^0.5 or the square root), than the larger factor q.
So by implication we can filter out any product of this exponent search that is greater than the square root of n.
Writing this code was a bit of a headache because I had to deal with potentially very large lists of bases and exponents, so I couldn't just use loops within loops.
Instead I resorted to writing a three state state machine that 'counted down' across these exponents, and it just works.
And now, in practice this doesn't immediately give us anything useful. And I had hoped this would at least give us *upperbounds* to start our search from, for any particular digit of a product's factors at a given magnitude. So the 12 digit (or pick a magnitude out of a hat) of an example product might give us an upperbound on the 2's exponent for that same digit in our lowest factor q of n.
It didn't work out that way. Sometimes there would be 'inversions', where the exponent of a factor on a magnitude of n, would be *lower* than the exponent of that factor on the same digit of q.
But when I started tearing into examples and generating test data I started to see certain patterns emerge, and immediately I found a way to not just pin down these inversions, but get *tight* bounds on the 2's exponents in the corresponding digit for our product's factor itself. It was like the complications I initially saw actually became a means to *tighten* the bounds.
For example, for one particular semiprime n=pq, this was some of the data:
n - offset: 6, exp: [[Decimal('2'), Decimal('5')], [Decimal('5'), Decimal('5')]]
q - offset: 6, exp: [[Decimal('2'), Decimal('6')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('5')]]
It's almost like the base 3 exponent in [n:7] gives away the presence of 3^1 in [q:6], even
though theres no subsequent presence of 3^n in [n:6] itself.
And I found this rule held each time I tested it.
Other rules, not so much, and other rules still would fail in the presence of yet other rules, almost like a giant switchboard.
I immediately realized the implications: rules had precedence, acted predictable when in isolated instances, and changed in specific instances in combination with other rules.
This was ripe for a decision tree generated through random search.
Another product n=pq, with mroe data
q(4)
offset: 4, exp: [[Decimal('2'), Decimal('4')], [Decimal('5'), Decimal('3')]]
n(4)
offset: 4, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('3')]]
Suggesting that a nontrivial base 3 exponent (**2 rather than **1) suggests the exponent on the 2 in the relevant
digit of [n], is one less than the same base 2 digital exponent at the same digit on [q]
And so it was clear from the get go that this approach held promise.
From there I discovered a bunch more rules and made some observations.
The bulk of the patterns, regardless of how large the product grows, should be present in the smaller bases (some bound of primes, say the first dozen), because the bulk of exponents for the factorization of any magnitude of a number, overwhelming lean heavily in the lower prime bases.
It was if the entire vulnerability was hiding in plain sight for four+ years, and we'd been approaching factorization all wrong from the beginning, by trying to factor a number, and all its digits at all its magnitudes, all at once, when like addition or multiplication, factorization could be done piecemeal if we knew the patterns to look for.7 -
When you write an efficient piece of code and because the legacy database is too slow to return the data, you have to find a way to delay your processing instead of finding a way to speed up the database web service.1

I made a point to the management that people are unnecessarily reworking things and throwing away. And all products should have a product owner and they should give requirements. So the management called the same guy(who fucking does pointless rewrites in the name of code cleanup) and said come up with a solution. The guy came with a solution of Agile + Jira and a whole fucking process behind it. So guess what, we are having pointless meetings when we can just finish and ship deliverables.
The management successfully founded an efficient way to effectively waste time. Kuddos.3 -
This is why we can never have enough software developers
It's true. No matter how many people learn to program, there will never be enough people who know how to program. They don't have to be very good at it either. It is now a required skill.
Minimum wage in first world countries is way above 5$ per hour. A Raspberry PI 3B costs 40$, or at most 1 day of work for the worst paid jobs. And it will run for years, and do routine tasks up to thousands of times faster than any employee. With that, the only excuse that people still do routine tasks, is the inaccessibility of coder time.
Solution: everybody should know how to write code, even at the simplest level.
Blue-collar jobs: they will be obsolete. Many of them already are. The rest are waiting for their turn.
Marketing people - marketing is online. They need to know how to set up proper tracking in JS, how to get atomic data in some form of SQL, how to script some automated adjustments via APIs for ad budgets, etc. Right now they're asking for developers to do that. If they learn to do that, they'll be an independent, valued asset. Employers WILL ask for this as a bonus.
Project Managers - to manage developers, they need to know what they do. They need to know code, they have to know their way around repositories.
QA staff - scripted tests are the best, most efficient tests.
Finance - dropping Excel in favor of R with Markdown, Jupyter Notebooks or whatever, is much more efficient. Customizing / integrating their ERP with external systems is also something they could do if they knew how to code.
Operations / Category Management - most of it would go obsolete with more companies adopting APIs as a way to exchange important information, rather than phone calls and e-mails.
Who would not be replaced or who wouldn't benefit from programming? Innovative artists.
A lot of it might not be now now, but the current generation will see it already in their career.
If we educate people today, without advanced computer skills and some coding, then we are educating future deadbeats.
With all this, all education should include CS. And not just as a mandatory field or something. Make it more accessible, more interesting, more superficial if needed. Go straight to use cases, show its effectiveness in the easiest way possible. Inquisitive minds will fill in the blanks, and everyone else will at least know how to automate a part of their work. -
I haven't chimed in on this spaces vs tabs war at all on this platform, mostly because I personally don't care and adapt to my work's/project's conventions, but I just have to put this out there now.
I am honestly so confused about the entire thing since seeing a lot of recent rants on the topic. I was originally conditioned to believe that the majority of devs in the world were FOR spaces over tabs. Thus, whenever I start a project, I default to spaces.
Contrary to that, it seems most devs here (or at least those who enjoy instigating some banter) actually prefer tabs. Now, I recently binged Silicon Valley and can't help but wonder if people around here are simply jumping on that band wagon for the sake of the joke.
Side note: I also thought Vim was more widely used over Emacs but Richard Hendricks asserts otherwise there too.
I know the main arguments for both sides - spaces yield code that looks the same in all editors while tabs produce smaller code. Anybody who argues that spaces are less efficient because you need to physically press the space bar 2/4/8/etc times is just retarded. If soft tabs weren't a thing, I don't think anybody would be on the side of spaces and for that reason I believe that episode in Silicon Valley was just trying to be overdramatized and push peoples' buttons.
All of that being said, I wonder if it's just a generational/field of development thing. Would it be wrong to propose that more older devs in the field of embedded and OS development (using C and the like) are in the spaces party while younger devs perhaps more into application and web dev (Javascript, C#, and shit) are all about tabs? I'm actually fresh out of university, but like I said my preference is spaces, though I don't really care.
I'm actually interested to find out what kind of environments breed these opposing mindsets so what do you guys think?2 -
Has anyone else used CodeBeat before? I just started an open source project that I plan to publish onto NPM so I created a public GitHub repo. Saw a marketplace tab and thought what the heck let's try it out. Found automated code reviewing software and gosh darn! Their GPA style grading system makes me want to write some pretty efficient code!
Has anyone else had the pleasure of using it?1 -
Do the hard stuff first. Then everything else looks easy. Make a mess of the code, then fix it and make it efficient.4

Thinking really hard about starting my own retro pc collection starting with the NEC pc-98 ......hmmmmmm wondee how my wife would feel about me spending money in this shit
Recently I have taken to all things retro tech, always liked it really, specially since my mom showed me pics of me playing with an old commodore 64 when i was younger as well as another of a family friend showing me the sharp 68k this shit fuels my appetite for knowing more about the programming ways of the old school coders. Some pretty interesting stuff, I feel that the newer generations would benefit greatly by knowing the things we had to do in order to build efficient programs back in the day. Not to say that I was part of that at all. I was born in 1991, how I came to see these systems is unknown and forgotten by me, but something that none the less os part of my story in computing.
Because of the industry that surrounds me I have been dealing with working with web development, but shit is really not that much of a passion of mine, had I the skills more than the academic knowledge I would love to work with low level C code all day, I just feel that the things that developers do there are so much more interesting than handilg web development, web development is tedious and a current shitstorm, not to say that shit was not like that for the programmers that i am referencing, but i just want more.
Web development has made me a successful man, at 28 i am the head of my department, I might sound like a Disney princess but I want more, I want more knowledge and more experience in different areas of Computer Science. I want to know it all and it seems like time continuously goes against me.
Oh well, here is to a new year lads, see what i can do.3 -
Looks like Android studio's artificial java to kotlin converter learned faster to write better kotlin than my shitty brain :/
People from java background, where did you learned to write efficient kotlin code and how?
Where to learn how to write that famous "kotlin's super precise and small , ugly ass anonymous looking code full of keywords , that only work when arranged in a particular pattern and defies my all previous knowledge of oop , java and good practices " code?
I really wish to learn, since android and google seems to be heading towards this beautiful new shit1 -
I think I would be much more efficient if I didn't have to sit on a chair and look at the screen while coding. Often it is so hindering to type with my fingers and I just wish I could code directly with my brain. 😶

Question: How would you reimagine the dev interview process, trying to make it efficient to find ingenious freshers?
I'm gonna be hiring full MERN stack dev freshers soon. I hate coding interviews, and I just want to test their ingenuity and problem solving, not if they can code a textbook algorithm.
Plan so far was to ask them questions like: "What happens when you like a link in the browser" to gauge how deep they could track a request and understand the internet infrastructure.
And make them audit gpt generated react code, and optimize it.
What're your thoughts, folks?8 -
How is a "web app" any better than a "web site"?
All a "web app" does is adding a JavaScript program as a middle-man between the browser and the server.
Where as "web sites" instantly deliver content, "web apps" deliver JavaScript code that then loads the content and puts it on the page.
A "web site" serves the browser useful content on a silver plate (metaphorically speaking), where as "web apps" serve some JavaScript code and the browser has to do the heavy lifting.
It appears that the only benefit of "web apps" is the fancier name. "App" sounds fancy while "site" sounds mundane. But technically, a "web app" is worse than a "web site". It's both slower and vulnerable to scripting errors.
Why would anyone in their right mind choose to create a web "app" over a web "site" to load text and a bunch of pictures?
I get it, some things such as posting comments without reloading the page and loading new search results when scrolling down are not possible without JavaScript, but why use JavaScript for everything, even where it wouldn't be necessary?
JavaScript should never be required to show a bunch of boxes containing pictures and some text. JavaScript is intended to enhance web sites, not to load entire websites.
As web developer Jake Archibald said, "[100% of] your users are non-JS while they're downloading your JS" ( https://twitter.com/jaffathecake/... ).
See also: I miss the good times when the web was lightweight. ( https://devrant.com/rants/9987051/... )
"App" is not an excuse: https://jakearchibald.com/2013/...
I am sad Archive.org switched to being a web app. But I applaud them for resisting that trend longer than most other large sites.28 -
The debate between using tabs or spaces for indentation in code is a long-standing argument among software developers. Those who prefer using tabs argue that it takes up less space and is more efficient, while those who prefer spaces argue that it allows for more consistency and easier readability.
Many developers have strong opinions on this issue and believe that their preferred method is the only correct one. Some even go as far as to say that using the wrong method can negatively impact their ability to work with the code.
Regardless of which side of the debate someone falls on, it's a common source of frustration and humor among developers. The argument often devolves into jokes and sarcastic comments, with both sides poking fun at the other's preferred method.
Despite the often lighthearted nature of the debate, it highlights the importance of code readability and maintainability, as well as the differences in personal preferences and workflows that can arise within the tech community.19 -

I'm an iOS developer and I cringe when I read job specs that require TDD or excessive unit testing. By excessive I mean demanding that unit tests need to written almost everywhere and using line coverage as a measure of success. I have many years of experience developing iOS apps in agencies and startups where I needed to be extremely time efficient while also keeping the code maintainable. And what I've learned is the importance of DRY, YAGNI and KISS over excessive unit testing. Sadly our industry has become obsessed with unit tests. I'm of the opinion that unit tests have their place, but integration and e2e tests have more value and should be prioritised, reserving unit tests for algorithmic code. Pushing for unit tests everywhere in my view is a ginormous waste of time that can't ever be repaid in quality, bug free code. Why? Because leads to making code testable through dependency injection and 'humble object' indirection layers, which increases the LoC and fragments code that would be easier to read over different classes. Add mocks, and together with the tests your LoC and complexity have tripled. 200% code size takes 200% the time to maintain. This time needs to be repaid - all this unit testing needs to save us 200% time in debugging or manual testing, which it doesn't unless you are an absolute rookie who writes the most terrible and buggy code imaginable, but if you're this terrible writing your production code, why should your tests be any better? It seems that especially big corporate shops love unit tests. Maybe they have enough money and resources to pay for all these hours wasted on unit tests. Maybe the developers can point their 10,000 unit tests when something goes wrong and say 'at least we tried'? Or maybe most developers don't know how to think and reason about their code before they type, and unit tests force them to do that?12

Programmers are usually notoriously bad at guessing which parts of the code are the primary consumers of the resources. It is all too common for a programmer to modify a piece of code expecting see a huge time savings and then to find that it makes no difference at all because the code was rarely executed. - Jon Louis Bentley, Writing Efficient Programs9

Sometimes I hate the limitations that being a mobile dev puts on your code, processor, memory, battery, signal and wifi limitations are all things that have to be worked round, however I couldn't imagine doing anything else and it's taught how to write concise and efficient code

!rant but a question...
I know that with the vast examples/tutorials online this may not be necessary, but I wanted to ask the community if you guys/gals would recommend going back to school to get a formal CS education or if it would be a waste of time, money, and resources compared to just using web based sources? I've tried the college thing 3 times when I was younger but couldn't concentrate and lacked the discipline to focus and finish classes. But I'm a bit older now and wanted to know if you would recommend going back to school or if time would be better spent performing self-study and learning from home?
I'm still extremely new to coding and programming and only have basic knowledge of actual coding and a lot of the theoretical stuff in programming is completely foreign to me. Like for example, how to optimize code. I know that refactoring code to have a smaller more efficient footprint is always desirable, when it doesn't interfere with readability, but I'm unaware of where/how to modify code to run efficiently. Of course that may be wayyy to advanced for my use cases anyway 😂.
I'm trying to teach myself python as it seems like a great language for starting out and getting to understand the concepts of programing. Plus, it can be used directly in my line of work as well as side projects that I wanted to try my hand at.
Thank you in advance for your recommendations everyone!2 -
Ideas I've had over the years that could pan out and be useful:
SMS-DB: Stands for SMS-Data Burst. Used to allow those with low cell signal or no data plan to transfer data between a phone and some client via the standard SMS text space. Would be slow, but would act kinda like dial-up over SMS (as mobile lines are compressed on all service levels, even LTE, so traditional dial-up wouldn't work!) I have a general idea on how packets would be laid out, but that's about it so far...
everything2PNG: Allows one to transpose any file's data into a PNG with a 3 byte per pixel (full color RGB), which allows for a "compression" of sorts (about 91, 93% on preliminary tests) AND allowing further, more efficient compression of the resulting file. (Plus... it's just kinda cool to see files transposed as PNGs.) I actually have a simple transposer to go to PNG, but can't yet go back. Large files (around 600MB) use upwards of 4GB with efficient paging and other optimizations via NumPy so far, so it's not *viable* yet, but it's coming along nicely.
RPi-GPIO Interconnection Bus: A master/slave or round robin method to allow for Raspberry Pis to communicate using GPIO, which can help free up network bandwidth in RPi cloud computing clusters. At most, this'd allow for 4 bits used for pushing to the GPIO "bus", and 4 bits used for pulling from the "bus". 8 pins total are usually unused minimum, so either 3 or 4 pins for upload, 3 or 4 for download, and potentially 1 or 2 for commands, general non-data communication, etc. I made a version of this concept using Round Robin for a client, but it was horribly slow. (I also don't have distribution rights for the code, so i'm working from scratch.) Definitely doable. -
<assumption>If there are no fundamental laws constraining the existence of simulated consciousness</assumption>, I would throw in my lot in working towards developing an AGI.
Since there is infinite time to learn any skill and <assumption>it is possible to learn or invent whatever software or mathematical framework is required for such a goal</assumption>, I would get down to that, learning and creating various new forms of mathematical frameworks and required software tools.
<assumption>Engineers usually work best without another fellow human on the project</assumption>, so I will set up automation for tasks that do benefit from multiple minds on a project, in the form of low-level artificial intelligence that I have to work on as a prerequisite for the main goal.
Once the critical mass is hit where the code can keep self-improving and produce more iterations of itself that are better, I sit back and start with my long, long to-watch/to-read list and try to finish as much as I can before the AGI I created would <assumption>repurpose all of our mortal flesh for more efficient use.</assumption>
The only remnant of the existence of humanity will be the influence on the initial design of the code based sentience that exists now.

So the saga of broken fucking everything continues at work, and I'm managing it, effectively, and doing it correctly on the first go-round. It's a long process though, because the two retards who preceded me were equally inept for completely different, yet equally disruptive and destructive reasons. The first dude was just plain psychotic, probably still is. I'd post some of his code, but I don't want anyone's face to melt off like those Nazi dudes at the end of Raiders of the Lost Ark. I can handle it because I'm constantly inebriated, which is not as fun as it sounds. If you have to ask yourself if you can handle it, you probably aren't, unless you've had to Uber to/from work due to still being fucking drunk. Anyway, enough about that, and it was only like twice. The rest of the times, I was more blazed than Jerry Garcia at a weed smoking contest. Moving along.
UPS shipping labels broke two weeks ago, I fixed it, but these fucking 10xers jointly decided to not only never implement anything resembling error handling, other than EMPTY GOD DAMN "try/catch"es (empty catch, wow so efficient), and instead of using COMMENTS, which I know are a new thing, they'd wrap blocks of code in something like: if 1 = 0 {} FUCK YOU DICKFACES. As I was saying before I got emotional again, they tied the success to all kinds of unrelated, irrelevant shit. I'm literally needle/haystacking my way through the entire 200GB codebase, ALONE, trying to find all the borked things. Helpfully, my phone is ringing all the time from customer service, complaining about things that are either nothing to do with the site, or due to user stupidity, 75% of the time.
A certain department at my company relies on some pretty specific documents to do their job, and these documents are/were generated from data in the database. So until I can find and fix all of the things, I've diverted my own attention as much as possible to the rapid implementation of a report generation microservice so that no one elses work is further disrupted while I continue my cursed easter egg hunt from fucking hell.
After a little more than two days, I'm about to lauch a standalone MS to handle the reports, and it's unfortunately more complicated than I'd like, because it requires a certain library that isn't available on Winblows, so I've dockerized the application. Anyway, just after lunch, I've finished my final round of tests, and I'm about ready to begin migrating it to the server and setting up (shitty fucking shit) IIS to serve it appropriately. At this point, this particular report has been unavailable by web for about 8 days.
A little after lunch, and with no forewarning of any kind, the manager of managers runs upstairs and screams at me to "work faster" and that "this needs to be back online RIGHT NOW", but I also know that this individual is going to throw a fit if things on this pdf aren't a pixel perfect match. So I just say "that's some amazing advice, I wish I'd had the foresight to just do it better and work faster". Silence for a good five seconds, then I follow up with "please leave and let me get back to my work". At that moment from around the corner, my "supervisor" suddenly, magically even, remembers that he has had the ability to print this crucial, amazingly super fucking important document all along, despite me directly asking him a week ago, and he prints it and takes it where it needs to go. In the time that it takes him to go to that other department and return, I deploy my service.
I spent the rest of the day browsing indeed and linkedin jobs, but damn this market is kinda weird right now, yeah?2 -
Together with colleagues from University of Zurich I am conducting a survey about skills for code review! With this survey, we aim to investigate skills that reviewers need to perform an efficient code review. Our main goal is to improve developers' code review practices. Therefore, we are looking for developers with experience as code reviewers. This questionnaire takes 15-20 minutes and consists of 21 questions.

Does any of you have the compulsion to micro-optimize every bit of code that you write? How do you deal with it?
I'm not just talking about algorithmic optimizations, but the real nitty gritty stuff. I'm talking about using bit fiddling to avoid if statements where speculative processors might make mispredictions. Anything that might make a program compile to fewer machine instructions or avoid extra stack frame overhead.
This all started a year ago when I took a systems programming course at my university, and started learning C and C++. But I find myself doing this in the wrong places. Who cares if this trivial program that I wrote runs in 1.2 or 0.6 seconds? My future employers won't care if my code is 10% more efficient when it takes four times as long to write.
It's gotten to the point that I can't bring myself to use languages like Python because I don't know how it's implemented under the hood and can't predict how the different ways I could write a function will affect performance. How do I bring myself to trust that the compilers (or interpreters) and the programmers that wrote them will be sufficiently optimal, and just move on? 😩4 -
Nothing says asshole like a guy who won't approve your MR even though the feature is working but they prefer implementing it using their preferred approach.
Different coding styles for different folks. What matters is that the approach used is efficient, working and tested. But oh no, you have to write the code exactly how they want it.
Good thing we're free to merge our own MR when the reviewer takes more than two days to merge it.4 -
What we will miss, if he really softens:
In fact, if the reason is stated as "it makes debugging easier", then I fart in your general
direction and call your mother a hamster.
In short: just say NO TO DRUGS, and maybe you won't end up like the Hurd people.
Of course, I'd also suggest that whoever was the genius who thought it was a good idea to read things ONE F*CKING BYTE AT A TIME with system calls for each byte should be retroactively aborted. Who the f*ck does idiotic things like that? How did they not die as babies, considering
that they were likely too stupid to find a tit to suck on?
Gnome seems to be developed by interface nazis, where consistently the excuse for not doing something is not "it's too complicated to do", but "it would confuse users".
I think the stupidity of your post just snuffed out everything
I think the OpenBSD crowd is a bunch of masturbating monkeys, in that they make such a big deal about concentrating on security to the
point where they pretty much admit that nothing else matters to them.
That is either genius, or a seriously diseased mind. - I can't quite tell which.
Christ, people. Learn C, instead of just stringing random characters together until it compiles (with warnings).
"and anybody who thinks that the above is
(a) legible
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it." -
Do you guys think students should get points for bad code?
For me once or twice it really saved my grades when I wrote the ugliest, least efficient and least readable code because my brain stuck during a exam.. It worked so I got full points.
Since I'm relatively inexperienced compared to you people it's hard for me to tell which is the very best approach to a problem. But I know when my code is just shit and I shouldn't be rewarded with good grades for it.
Is 'basically working' worth anything outside of school?7 -
I have a personal opinion and correct me if I'm wrong
Why does a programmer need to learn behind the scenes stuff (memory allocation).
I know it helps to understand the concepts better.
Why would I learn how the engine of a car works in order to drive a car ?.
And the only task is required from you to drive a car.
And literally you can code without knowing any of these stuff and since companies only need clean and efficient code.
Will it be really helpful to enhance your coding skills if you know behind the scenes stuff ?6 -
Looking at @striker28 's rant made me think of my time I did my MSc and I think it needs it's own separate rant so here it goes:
So I did an MSc at one of the big league unis in London. First clue was during week 1 where in one of the class a mature student asked whether there would be actual coding during the course. There was an audible gasp from everyone else! Once the lecturer said the unfortunatly they wouldn't be you could hear the sigh of relief from the students...
Next up was all the lectures being placed in the freakin' basement of the university in crap, smelly rooms with annoying ticking A/Cs whereas all the social siences, business and other subjects had lecture halls and classrooms above ground. The contempt for CS from the university's direction was palpable.
Then there was the relegation to the theory-only (i.e. abstract with pen/paper) "tutorial" to the hand of T/As with bugger-all teaching experience. In short most were terrible and should've found a way to abscond themselved from this obligation which was part of the terms of their phd grants unfortunatly.
Further into the course there was the "group project". Oh boy! Out of the 5 in the group my now mature student friend and I were the only one commiting to the repo. There was either no code and a lot of bullshit from the others or crap code that didn't even compile despite their assurances it was all good.. Someone clearly never actually coded and pressed "run" in their lives which is fucking surprising since they've managed to graduate with a BSc and get into a MSc somehow. None of the code "made" by the other 3 persons made it into the master branch for release.
The attitude was that of "We (hahahah) wrote loads of code. We'll get a great mark!". At that stage the core wasn't even complete and the software didn't work yet.
Some of the courses where teaching things already 10 years out of date and when lecturer where pressed on that the few mature students that happen to be there the answer was always "yes, we are planning to update it for next year". Complete bullshit. Didn't help that some of the code on the lecture slides was not even correct! I mean these guy are touted as "experts" in their field...
None of the teory during the entire year was linked to any coding. Everything was abstract with no ties to applied software engineering. I.e. nothing like the real world.
The worst is that none of the youger students realised they were being screwed over and getting very little value for their money. Perhaps one reason why these evaluation forms have such high scores given on them. If you haven't had a job and haven't lived outside academia yet there is nothing to compare it to. It tends to also fall into confirmation bias (hey it's a top UK university, it must be worth it afterall! Look how much they ask for).
By the end of the year I couldn't wait to get the hell out. One of the other mature student sumed it quite well: "I will never send my children here."
Keep in mind that the guy had just over a decade of software engineering experience in the industry and was doing this for fun.
In the end universities are not teaching institutions. The lecturers's primary job is research and their priorities match that. Lectures tend to be the most time efficient teaching format for the ones giving them but, on their own, are not for the consumer.
To those contemplating university for CS: Do the BSc. Get your algo/datastructure chops and learn the basic theory. It is interesting. Don't get discouraged by the subject just because it is taught badly.
Avoid the MSc unless you want to do a phd and go for an academic carrer. You are better off using that year and the money to learn more on your own and get into colaborative projects (open source) on top of some personal ones. Build up your portfolio. It will be cheaper and more interesting!2 -

I get so tired of people hating on PHP, Javascript and promoting Python or C#/Java.
Python is basically Perl with slightly different syntax plus has py2/py3 issues. And suffers from pip like js does from npm.
Java/C# started as application languages, while PHP started in web servers (again from Perl but at least it now has full object support). So comparing apples and oranges is one thing.
Another one is that people don't seem to know much about PHP / js (and tbh not even about the languages they are promoting) when they try to hate. That just comes off as lazy and borderline idiotic. Don't be that guy.
If you have had a bad experience, maybe you need to open the documentation instead of copying code from stack overflow.
Again, lazy and unprofessional.
Devs are supposed to be able to find the most efficient solution, that takes as little code as possible, not as little time from them when they arent familiar with the subject.
Damn Im angry right now, this rant really worked me up! :D6 -
Working as a Dev for a while now, I tell new people not to bother with it. There is never any job satisfaction as people in charge never understand the basics.
Instead of learning to write efficient code, figure out how to solve real business problems, work towards a maintainable flexible product to quickly deliver value on changing requirements, write automated tests to improve quality, maintainability and prevent live issues - basically do anything a good Dev strives for - you will just constantly end up working for people with no interest beyond the next couple days, on a shit code base that no one can understand, with people that don't want to learn anything about software design and just check boxes off.
Apart from pay this must be the worst career possible in a technical field.4 -
Finish my game. It will probably be shit because the concept just wasn't that good, but I will be able to extract 2-3 useful node modules once it's finished and tested properly. A VoIP system with overlapping rooms and an efficient co-browsing system without a serverside browser like Selenium are certain. Perhaps the plugin structure as well, but that's more architecture than code.1

This is the old code in net/ipv6/ip6_output.c:
mtu -= hlen + sizeof(struct frag_hdr);
and this is the new "improved" code that uses fancy stuff that wants
magical built-in compiler support and has silly wrapper functions for
when it doesn't exist:
if (overflow_usub(mtu, hlen + sizeof(struct frag_hdr), &mtu) ||
mtu <= 7)
goto fail_toobig;
and anybody who thinks that the above is
(a) legible
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it.
The code could *easily* have been done with just a single and
understandable conditional, and the compiler would actually have
generated better code, and the code would look better and more
understandable. Why is this not
if (mtu < hlen + sizeof(struct frag_hdr) + 8)
goto fail_toobig;
mtu -= hlen + sizeof(struct frag_hdr);
which is the same number of lines, doesn't use crazy helper functions
that nobody knows what they do, and is much more obvious what it
actually does.
I guarantee that the second more obvious version is easier to read and
understand. Does anybody really want to dispute this?
Really. Give me *one* reason why it was written in that idiotic way
with two different conditionals, and a shiny new nonstandard function
that wants particular compiler support to generate even half-way sane
code, and even then generates worse code? A shiny function that we
have never ever needed anywhere else, and that is just
compiler-masturbation.
And yes, you still could have overflow issues if the whole "hlen +
xyz" expression overflows, but quite frankly, the "overflow_usub()"
code had that too. So if you worry about that, then you damn well
didn't do the right thing to begin with.
So I really see no reason for this kind of complete idiotic crap.
Tell me why. Because I'm not pulling this kind of completely insane
stuff that generates conflicts at rc7 time, and that seems to have
absolutely no reason for being anm idiotic unreadable mess.
The code seems *designed* to use that new "overflow_usub()" code. It
seems to be an excuse to use that function.
And it's a f*cking bad excuse for that braindamage.
I'm sorry, but we don't add idiotic new interfaces like this for
idiotic new code like that.
Yes, yes, if this had stayed inside the network layer I would never
have noticed. But since I *did* notice, I really don't want to pull
this. In fact, I want to make it clear to *everybody* that code like
this is completely unacceptable. Anybody who thinks that code like
this is "safe" and "secure" because it uses fancy overflow detection
functions is so far out to lunch that it's not even funny. All this
kind of crap does is to make the code a unreadable mess with code that
no sane person will ever really understand what it actually does.
Get rid of it. And I don't *ever* want to see that shit again. -
NPM package – community-health-files
I've just built a NPM package: community-health-files
This package automates the creation and management of key files like CODE_OF_CONDUCT.md, BUG_REPORT.yml, and SECURITY.md for open-source projects. It simplifies the process of maintaining project guidelines, security policies, and codes of conduct, providing a more efficient and organized workflow.
This package helps open-source projects stay organized and compliant, saving you time and effort by handling the setup for you.
I'm always looking for feedback and contributions from the community—whether it's through improving the code, enhancing the documentation, or sharing your ideas.
🌟 Check it out, and if you find it helpful, consider adding a star on GitHub!

The timelines at my workplace are too short that it's impossible to actually build anything or observe procedures like testing, software techniques for maintaining oop code, telemetry and other things I may have learnt along the way
So application templates are the order of the day. They pull solutions off the shelf, edit the interface, hand over to clients at an alarming rate (sometimes, within a matter of days!). So yesterday, the cto asked for ways I can recommend that the team is made more efficient. He takes what I say very seriously, owing to Suphle's appendix chapter as well as the issues its blueprint set out to solve
Like I said, those do not apply here. I mean, the developers I've met are making do and winging it. I'm the one struggling to adapt to rummaging through templates and customise shit
Maybe I'm over thinking it cuz there's no sense in fixing something that's not broken. So far, only flaw I've observed (because the product designer has complained to me bitterly that the devs hardly ever translates his prototypes verbatim), is the need for a dedicated mobile developer (not that multifunctional, confused portfolio called "fullstack). But I didn't raise this since the time frames hardly even afford time for writing apis or writing mobile code. You'd be surprised to realise that everything a client can possibly ask for is already somewhere, built at a higher standard than you can replicate
My question now is, what other positive novelty can I bring aboard? How can this process be further optimised? If it can't, what suggestions outside regular software development or this work flow can I bring to the table?
Personally, I'm considering asking him to tell me bottlenecks if he has identified any. But it's very likely that he would already have begun working towards it if he knew them. I suspect he needs someone outside the system to see what is lacking or a new addition that could even be a distant, outlandish branch of the tech market, but drive the company towards more profit1 -
i can never understand the theme behind kotlin.
THEY DON'T HAVE A FUCKING TERNARY OPERATOR!!![?:]
Like before realizing this, i thought yeah jetbrains has decided to make android development a privileged hobby and non beginner friendly , so its now creating an encoding like language, in the false theme of " reducing code size"
But now they remove WORLDWIDE KNOWN, OPTIMIZED , EASY TO READ AND USE AND UNDERSTAND FEATURE of ternary operator and replacing it with less powerful but same looking elvis operator.( and stating that using if else for that is a better option)
Like why? if your goal is to make a shitty encoding language that makes everything shorter and most of the things optional, why remove the already efficient if else encoder?
God knows when this stupid language is going to stop my brain from getting blasted11
