Just sharing a thought.
A and B are 2 good friends.
in the last days of their college, both of them know that after this , life is about to come for them. they would be out of the comfort bubble and into the harsh world. they have a lot of paths in front of them, and they have to make choices now.
A is a very unsure of everything:
- He likes a bunch of things in which he would want a career in , but is afraid that his choice of interest isn't too good.
- He also don't like a bunch of things that he don't want to get stuck in , but is afraid that its either too good or too bad that eventually an average guy like himself would have to end up there .
- He also got a bunch of demons in himself which are the reason for his overconfidence, doubts and maybe his average results.
- he ends up trying a lot of things, giving average results in them due to his demons and lazy nature and end up regretting every of his choice. He does gets some success at the end, but he lives a terrible, sad life
Then there is Guy B:
- He's also an average, but he don't regret his choices. He also have a bunch of demons, but makes sure to keep them in check
- He makes choices and sticks with them. He only tries a path if he feels like so, he is not easily swayed by the choices of people around him. He has some firm beliefs.
- He ends up in career path that he is fully confident of, and doesn't regrets about it in the least. He too gets success.
I assumed( and hope) that both of these guys gets success. But i am sure one was just throwing stuff on the wall thinking that something would stick, and other was sure that he has a glue in his hand and it would definitely stick(even tho it might had not been a glue).
For the first guy the success was a surprise, a miracle that he didn't even believed that he got one. But for other, it was a long due reward that he was confident would someday come up for him
The practical case is usually that the first guy never gets to enjoy success and ends up regretting( like the ending of first guy's story) and second guy not only gets the success, but get it faster than he would have though( like the end of second guy's story)5
So, I was out cruising in my sports car the other day. Porsche, two seater, about 400 hp.
When I stopped at a red light I was next to a man driving his family of four in his Volkswagen. I revved my car to show my power, but he seemed unfazed by my superior engine. When the light became green I floored it, he didn't have a chance of catching up, I just left him behind and laughed. He's so stupid for driving that slow car.
I can't understand why anyone would ever want to drive a Volkswagen when they are just so obviously slow?
👆This is how you sound like when you compare languages only based on how fast they are.15
I've optimised so many things in my time I can't remember most of them.
Most recently, something had to be the equivalent off `"literal" LIKE column` with a million rows to compare. It would take around a second average each literal to lookup for a service that needs to be high load and low latency. This isn't an easy case to optimise, many people would consider it impossible.
It took my a couple of hours to reverse engineer the data and implement a few hundred line implementation that would look it up in 1ms average with the worst possible case being very rare and not too distant from this.
In another case there was a lookup of arbitrary time spans that most people would not bother to cache because the input parameters are too short lived and variable to make a difference. I replaced the 50000+ line application acting as a middle man between the application and database with 500 lines of code that did the look up faster and was able to implement a reasonable caching strategy. This dropped resource consumption by a minimum of factor of ten at least. Misses were cheaper and it was able to cache most cases. It also involved modifying the client library in C to stop it unnecessarily wrapping primitives in objects to the high level language which was causing it to consume excessive amounts of memory when processing huge data streams.
Another system would download a huge data set for every point of sale constantly, then parse and apply it. It had to reflect changes quickly but would download the whole dataset each time containing hundreds of thousands of rows. I whipped up a system so that a single server (barring redundancy) would download it in a loop, parse it using C which was much faster than the traditional interpreted language, then use a custom data differential format, TCP data streaming protocol, binary serialisation and LZMA compression to pipe it down to points of sale. This protocol also used versioning for catchup and differential combination for additional reduction in size. It went from being 30 seconds to a few minutes behind to using able to keep up to with in a second of changes. It was also using so much bandwidth that it would reach the limit on ADSL connections then get throttled. I looked at the traffic stats after and it dropped from dozens of terabytes a month to around a gigabyte or so a month for several hundred machines. The drop in the graphs you'd think all the machines had been turned off as that's what it looked like. It could now happily run over GPRS or 56K.
I was working on a project with a lot of data and noticed these huge tables and horrible queries. The tables were all the results of queries. Someone wrote terrible SQL then to optimise it ran it in the background with all possible variable values then store the results of joins and aggregates into new tables. On top of those tables they wrote more SQL. I wrote some new queries and query generation that wiped out thousands of lines of code immediately and operated on the original tables taking things down from 30GB and rapidly climbing to a couple GB.
Another time a piece of mathematics had to generate all possible permutations and the existing solution was factorial. I worked out how to optimise it to run n*n which believe it or not made the world of difference. Went from hardly handling anything to handling anything thrown at it. It was nice trying to get people to "freeze the system now".
I build my own frontend systems (admittedly rushed) that do what angular/react/vue aim for but with higher (maximum) performance including an in memory data base to back the UI that had layered event driven indexes and could handle referential integrity (overlay on the database only revealing items with valid integrity) or reordering and reposition events very rapidly using a custom AVL tree. You could layer indexes over it (data inheritance) that could be partial and dynamic.
So many times have I optimised things on automatic just cleaning up code normally. Hundreds, thousands of optimisations. It's what makes my clock tick.4
Google: hey website owner, use link rel preload for images loaded by CSS to reduce roundtrip delays. Chrome supports that, Safari also, and even Edge does.
Mozilla: we had some bug with preload back in FF 57 and our solution since has just been to disable preload per default. Done. Who would care about loading speed?
Also Mozilla: we have no idea why our market share has been plunging. Google is evil.9
Just because I don't believe in "the mission", doesn't mean I am not coming in and not giving up to ~60% every work day.
"I look for three things in a project: 1) Compelling work; 2) fun client; 3) astronomical fees. However, to have a successful project, I really only need two out of three. For example, I’ll do great work with fun people for nothing and still feel rewarded. Or, I’ll do great work for a mean, stupid client for outrageous money. Or, I’ll do boring work with somebody I like a lot for more money than one can imagine. Anytime I’m faced with only one of the three it’s time to rethink the relationship. Actually, it’s time to move on." - Lowell Williams
I went searching for a meme to explain my wife why I get frustrated when she comes to my home-office to ask if we should buy or not that air purifier we discussed once... found this. I think it helped, I hope it helps you too3
Not dev related but what is the fucking point of someone saying I'm going there to do that and when i ask them to show me THAT what they did they say "oh it was so bad I'm not gonna show you haha"
Like how do i explain it without being rude.....
Here's a savage example scenario
Your wife: "i just came back from a mountain in the middle of nowhere filming an ad and in gonna be in that ad"
You: "cool. Id love to see that ad, could you show it to me?"
Your wife: "noo i was so ugly and it was so bad im not gonna show u"
What are you gonna think? What was your wife filming secretly behind your back and she doesnt want to show you? Was she even filming in the first place? Or was she fucking a guy? What is one supposed to think of this conversation? Why fucking tell me ur gonna go there and do that and then not talk about it at all after doing it? What the FUCK who DOES THAT ???3
Was lead developer at a small startup, I was hiring and had a budget to add 3 new people to my team to develop a new product for the company.
Some context first and then the rant!
Candidate 1 - Amazing, a dev I worked with before who was under utilized at the previous company. Still a junior, but, she was a quick learner and eager to expand her knowledge, never an issue.
Candidate 2 - Kickass dev with back end skills and extras, he was always eager to work a bit more than what was expected. I use to send him home early to annoy him. haha!
Candidate 3 - Lets call him P.
In the interview he answers every question perfectly, he asks all the right questions and suggests some things I havent even thought of. CTO goes ahead and says we should skip the technical test and just hire the guy, his smart and knows what his talking about, I agree and we hire him. (We where a bit desperate at this stage as well.)
He comes in a week early to pick up his work laptop to get setup before he starts the next week, awesome! This guy is going to be an asset to the company, cant wait to have him join the team - The CTO at this stage is getting ready to leave the company and I will be taking over the division and need someone to take over lead position, he seems like the guys to do it.
The guys starts the next week, he comes in and the laptop we gave him is now a local server for testing and he will be working off his own laptop, no issue, we are small so needed a testing stack, but wasnt really needed since we had procedures in place for this already.
Here is where everything goes wrong!!! First day goes great... Next day he gets in early 6:30am (Nice! NO!), he absolutely smells, no stinks, of weed, not a light smell, the entire fucking office smells of weed! (I have no problem with weed, just dont make it my problem to deal with). I get called by boss and told to sort this out people are complaining! I drive to office and have a meeting with him, he says its all good he understands. (This was Friday).
Monday comes around - Get a call from Boss at 7:30am. Whole office smells like weed, please talk to P again, this cannot happen again. I drive to office again, and he again says it wont happen again, he has some issues with back pain and the weed helps.
Tuesday - Same fucking thing! And now he doesnt want to sign for the laptop("server") that was given to him, and has moved to code in the boardroom, WHERE OUR FUCKING CLIENTS WILL BE VIEWING A DEMO THAT DAY OF THE PRODUCT!! Now that whole room smells like weed, FML!
Wednesday - We send P a formal letter that he is under probation, P calls me to have a meeting. In the meeting he blames me for not understanding "new age" medicine, I ask for his doctors prescription and ask why he didnt tell me this in the interview so I could make arrangements, we dont care if you are stoned, just do good work and be considerate to your co-workers. P cant provide these and keeps ranting, I suggest he takes pain killers, he has none of it only "new age" medicine for him.
Thursday - I ask him to rather "work" from home till we can get this sorted, he comes in for code reviews for 2 weeks. I can clearly see he has no idea how the system works but is trying, I thought I will dive deeper and look at all of his code. Its a mess, nothing makes sense and 50% of it is hard coded (We are building a decentralized API for huge data sets so this makes no sense).
Friday - In code review I confront him about this, he has excuses for everything, I start asking him harder questions about the project and to explain what we are building - he goes quiet and quits on the spot with a shitty apology.
From what I could make out he was really smart when it came to theory but interpreting the theory to actual practice wasnt possible for him, probably would have been easier if he wasnt high all the time.
I hate interview code tests, but learned a valuable lesson that day! Always test for some code knowledge as well even if you hate doing it, ask the right questions and be careful who you hire! You can only bullshit for so long in coding before someone figures out that you are a fraud.16
Am I the only one who pronounces git reflog as re-flog rather than ref-log? As in being whipped again6
The first time I realized I wasn't as good as I thought I was when I met the smartest dev I've ever known (to this day).
I was hired to manage his team but was just immediately floored by the sheer knowledge and skills this guy displayed.
I started to wonder why they hired outside of the team instead of promoting him when I found that he just didn't mesh well with others.
He was very blunt about everything he says. Especially when it comes to code reviews. Man, he did /not/ mince words. And, of course, everyone took this as him just being an asshole.
But being an expert asshole myself, I could tell he wasn't really trying to be one and he was just quirky. He was really good and I really liked hanging out with him. I learned A LOT of things.
Can you imagine coming into a lead position, with years of experience in the role backing your confidence and then be told that your code is bad and then, systematically, very precisely, and very clearly be told why? That shit is humbling.
But it was the good kind of humbling, you know? I really liked that I had someone who could actually teach me new things.
So we hung out a lot and later on I got to meet his daughter and wife who told me that he had slight autism which is why he talked the way he did. He simply doesn't know how to talk any other way.
I explained it to the rest of the team (after getting permission) and once they understood that they started to take his criticism more seriously. He also started to learn to be less harsh with his words.
We developed some really nice friendships and our team was becoming a little family.
Year and a half later I had to leave the company for personal reasons. But before I did I convinced our boss to get him to replace me. The team was behind him now and he easily handled it like a pro.
That was 5 years ago. I moved out of the city, moved back, and got a job at another company.
Four months ago, he called me up and said he had three reasons for us to meet up.
1. He was making me god father of his new baby boy
2. That they created a new position for him at the company; VP of Engineering
3. He wanted to hang out
So we did and turns out he had a 4th reason; He had a nice job offer for me.
I'm telling this story now because I wanted to remind everyone of the lesson that every mainstream anime tells us:
Never underestimate the power of friendship.22
Haven’t been on here for ages, but I felt like I needed to post this:
This is long, and it might make you cry.
A couple of months back I worked for a completely clueless dude who had somehow landed a contract for a new website for a huge company. After a while he realised that he was incapable of completing the assignment. He then hired me as a subcontractor and I deleted literally everything he had done and started from scratch. He had over promised and under explained what needed to be done to me. It took many sleepless nights to get this finished with all the amendments and I had to double my pricing because he kept changing the brief.
Even after doubling my prices I still put in way too many hours of work. At one point I had enough and just ghosted the guy as I had done what he asked, and when he submitted it to them they wanted changes. He couldn’t make the changes, so I had to. He wouldn’t pay me extra though. I decided it wasn’t worth my time.
A couple of days ago I heard from him again. He had found another subcontractor to finish the changes. He still needed a few things though, so he promised me that I would get paid after fixing those things. I looked at the few things he had listed in our KANBAN and thought it was a few easy tasks.. until I opened the project..
I had my computer set up to sync with his server because he wanted everything done live and in production. So I naturally thought I would just “sync down” everything that the other subcontractor had done.
Here is where the magic started to happen.. I started the sync and went to grab a glass of water, and it was still running when I came back. I looked at the log and saw a bunch of “node_module” files syncing - around 900 folders. Funny thing is; neither the site nor server has anything to do with node..
I disregarded this and downloaded the files in a more manual fashion to a new folder. Interestingly I could see that my SCSS folders had not been touched since I stopped working on the project.. interesting, I thought to myself..
Turns out, the other subcontractor had taken my rendered and minimised CSS file, prettified it and worked from there. This meant that the around ~1500 lines of SCSS neatly organised in around 20 files was suddenly turned into a monster of a single CSS file of no less than 17300 lines.
I tried to explain to the guy that the other subcontractor had fucked up, but he said that I should be able to fix it since I was the one that made it initially. I haven’t replied. My life is too short for this.9
I found out recently that Facebook is embedding tracking data in the form of IPTC metadata in images that you upload. This way the images can be tracked even after you download them.
Because I'm an anarchist and just want to watch the world burn a little, I made a tiny server to replace the id hash that they embed with a random one, just to see if I can't fuck with their algorithm a little bit.

29-year veteran here. Began programming professionally in 1990, writing BASIC applications for an 8-bit Apple II+ computer. Learned Pascal, C, Clipper, COBOL. Ironic side-story: back then, my university colleagues and I used to make fun of old COBOL programmers. Fortunately, I never had to actually work with the language, but the knowledge allowed me to qualify for a decent job position, back in '92.
For a while, I worked with an IBM mainframe, using REXX and EXEC2 scripting languages for the VM/SP operating system. Then I began programming for the web, wrote my first dynamic web applications with cgi-bin shell and Perl scripts. Used the little-known IBM Net.Data scripting language. I finally learned PHP and settled with it for many, many years.
I always wanted to be a programmer. As a kid I dreamed of being like Kevin Flynn, of TRON - create world famous videogames and live upstairs my own arcade place! Later on, at some point, I was disappointed, I questioned my skills, I thought I should do more, I let other people's expectations make feel bad. Then I finally realized I actually enjoy a quieter, simpler life. And I made peace with it.
I'm now like the old programmers I used to mock 30 years ago. There's so much shit inside my brain. And everything seems so damn complex these days. Frameworks, package managers, transpilers, layers and more layers of code. I try to keep up. And the more I learn, the more it seems I don't know.
Sometimes I feel tired. Yet, I still enjoy creating things and solving problems with programming. I still have fun learning. And after all these years, I learned to be proud of my work, even if it didn't turn out to be as glamorous as in the movies.34
Some ideas for variable names. Thank me later :))

My team: gets fired
8 other colleagues: here’s our notice, we leavin
Love it, they’re left with 4 devs so good luck finding people who know how to work in your 20 year old legacy that every app in ur company is built on lul10
