Search - "and codes a lot"
Dev: boss, there are some abnormalities and confusion in the client's specifications.
Dev: Shouldn't we get clear about them and then start coding?
Boss: No need. We assume and code. Then show them to our clients and then ask for their opinions. We will change again according to their opinion.
A few months later....
Dev: *seeing so many specifications change and realizing now have to refactor a lot of codes* , FML.16
I am a PHP developer.
Yeah, "another PHP is awful" rant... no, not really.
It's just unsuitable for some ambitious projects, just like Ruby and Python are.
First of all, DO NOT EVER use Laravel for large enterprise applications. The same goes for RoR, Django, and other ActiveRecord MVCs.
They are all neat frameworks for writing a todo app, as a better-than-wordpress flexible blogging solution, even as a custom webshop.
Beyond 50k daily users, Active Record becomes hell due to it's lazy fat querying habits. At more than a million users... *depressed sigh*.
PHP is also completely unsuitable for projects beyond 5M lines of code in my opinion. At more than 25M lines... *another depressed sigh*.
You can let your devs read Clean Code and books about architecture patterns, you can teach them about SOLID & DRY, you can write thousands of tests... it doesn't matter.
PHP is scaffolding, it's made of bamboo and rope. It's not brick or concrete. You can build quickly, but it only scales up to a certain point before it breaks in multiple places.
Eventually you run into patterns where even 100% test coverage still doesn't guarantee shit, because the real-life edge cases are just too complex and numerous.
When you're working on a multi-party invoicing system with adapters for various tax codes, or an availability/planning system working across timezones, or systems which implement geographical routefinding coupled to traffic, event & weather prediction...
PHP, Python, Ruby, etc are just missing types.
Every day I run into bugs which could have been prevented if you could use ADTs in a generic way in PHP. PHP7 has pretty good typehints, and they prevent a lot of messy behavior, but they aren't composable. There is no way to tell PHP "this method accepts a Collection of Users", or "this methods returns maybe either an Apple or a Pear, and I want to force the caller to handle both Apple/Pear and null".
Well, you could do that, but it requires a lot of custom classes and trickery, and you have to rewrite the same logic if you want to typehint a "Collection of Departments" instead of "Collection of Users" -- i.e., it's not composable.
Probably the biggest issue is that languages with a (mostly) structural type system (Haskell, Rust, even C#/JVM languages to some degree, etc) are much slower to develop in for the "startup" era of a project, so you grab a weak, quick prototyping language to get started.
Then, when you reach a more grown up phase, you wish you had a better type system at your disposal...28
So, here's how online payment works in my country:
1. The selling website creates a hidden <form> and populates it with product ID, price and etc.
3. User enters credit info, and submits. If all is right, the bank creates another hidden <form>, and populates is with status code and an invoice ID.
4. Said form is then posted back to the selling website.
I don't know how the programmers behind this scenario call themselves programmers if they don't know basic things about server-side only verifications, but thanks to them I've been buying a lot of products for free these past years. 😂😂
How? 1. Just install Requestly, Tampermonkey and enable Chrome's dev tools.
2. Change price to zero, and the bank's response code to success.
P. S. I have notified the people behind this, but they don't listen and go fix their codes. Oh well, serves them right.13
This is going to be a long rant, coz this is the only way to vent out my frustration against our tech head.
Yesterday, while our fucking twat tech head was playing around in company aws account, he terminated the production server. By mistake, apparently. Coz he doesn't know shit about server management. But that egoist ass won't admit and fucked the production server.
And then ran away. We developers sprang into action. Updated dns to point to staging server, setup virtual hosts, env files, point to prod database, force flush dns cache. All systems were up and running in 30 mins. And since it was staging server, it had lot of untested features and codes, and we spent rest of the day fixing the bugs.
And that tech head, who ran away hiding his tail between his legs, after he fucked the server, came back after systems were up. And started cracking jokes, that "so many features got released in 1 day" . "We cut server cost by shutting down 1 server."
We were struggling and working in full throttle to make the services running again. And that fuckity fucker was cracking jokes.
And I don't even know what excuse he gave to ceo for the downtime. I am pretty sure he would have made up some crappy excuse to hide his fucking mistake. That ass never admits his mistake. I am thinking to go to ceo today and tell the real story and get that faggot head fired or at least a strict warning.4
Him: I am a software engineer.
Me: That is great, do you use specific technology?
Him: Multiple, but my basic is YouTube.
Me: Sorry, I didn't get it? You mean YouTube API?
Him: No need, I have a channel on YouTube... And podcast a lot about software engineering.
Me: So you don't write code anymore?
Him: I didn't, engineering is more than writing codes.
Me: Yes it is....13
Encouraged a friend to quit his current job. He is mentally unstable now because of his employer. His jerk employer harasses him and blames him stuff he didn't do. Blames him pre-existing bugs/bad features/bad codes from three years ago! He just got employed by that jerk employer two months ago. I know how my friend works because he was once my team leader for 19 months. He works harder and is one of the best devs I've ever met. He doesn't deserve a dickhead employer and that dickhead employer DOES NOT deserve a talented(skillful) software engineer like my friend. If anything happens to my friend, a lot of people will be hunting him down.3
Well... I had in over 15 years of programming a lot of PHP / HTML projects where I asked myself: What psychopath could have written this?
(PHP haters: Just go trolling somewhere else...)
In my current project I've "inherited" a project which was running around ~ 15 years. Code Base looked solid to me... (Article system for ERP, huge company / branches system, lot of other modules for internal use... All in all: Not small.)
The original goal was to port to PHP 7 and to give it a fresh layout. Seemed doable...
The first days passed by - porting to an asset system, cleaning up the base system (login / logout / session & cookies... you know the drill).
And that was where it all went haywire.
I really have no clue how someone could have been so ignorant to not even think twice before setting cookies or doing other "header related" stuff without at least checking the result codes...
Basically the authentication / permission system was fully fucked up. It relied on redirecting the user via header modification to the login page with an error set in a GET variable...
Uh boy. That ain't funny.
Ported to session flash messages, checked if headers were sent, hard exit otherwise - redirect.
But then I got to the first layers of the whole "OOP class" related shit...
It's basically "whack a mole".
Whoever wrote this, was as dumb and as ignorant to build up a daisy chain of commands for fixing corner cases of corner cases of the regular command... If you don't understand what I mean, take the following example:
Permissions are based on group (accumulation of single permissions) and single permissions - to get all permissions from a user, you need to fetch both and build a unique array.
Well... The "names" for permissions are not unique. I'd never expected to be someone to be so stupid. Yes. You could have two permissions name "article_search" - while relying on uniqueness.
All in all all permissions are fetched once for lifetime of script and stored to a cache...
To fix this corner case… There is another function that fetches the results from the cache and returns simply "one" of the rights (getting permission array).
In case you need to get the ID of the other (yes... two identifiers used in the project for permissions - name and ID (auto increment key))...
Let's write another function on top of the function on top of the function.
My brain is seriously in deep fried mode.
Untangling this mess is basically like getting pumped up with pain killers and trying to solve logic riddles - it just doesn't work....
So... From redesigning and porting from PHP 7 I'm basically rewriting the whole base system to MVC, porting and touching every script, untangling this dumb shit of "functions" / "OOP" [or whatever you call this garbage] and then hoping everything works...
A huge thanks to AURA. http://auraphp.com/
It's incredibily useful in this case, as it has no dependencies and makes it very easy to get a solid ground without writing a whole framework by myself.
You know it's gonna be a good Friday when the dev team takes a work trip to the store to get beer.
Happy Friday everyone!3
So recently I did a lot of research into the internals of Computers and CPUs.
And i'd like to share a result of mine.
First of all, take some time to look at the code down below. You see two assembler codes and two command lines.
The Assembler code is designed to test how the instructions "enter" and "leave" compare to manually doing what they are shortened to.
Enter and leave create a new Stackframe: this means, that they create a new temporary stack. The stack is where local variables are put to by the compiler. On the right side, you can see how I create my own stack by using
mov rbp, rsp
sub rsp, 0
(I won't get into details behind why that works).
Okay. Why is this even relevant?
Well: there is the assumption that enter and leave are very slow. This is due to raw numbers:
In some paper I saw ( I couldn't find the link, i'm sorry), enter was said to use up 12 CPU cycles, while the manual stacking would require 3 (push + mov + sub => 1 + 1 + 1).
When I compile an empty function, I get pretty much what you'd expect just from the raw numbers of CPU cycles.
HOWEVER, then I add the dummy code in the middle:
mov eax, 123
add eax, 123543
mov ebx, 234
and magically - both sides have the same result.
For one thing, there is CPU prefetching. This is the CPU loading in ram before its done executing the current instruction (this is how anti-debugger code works, btw. Might make another rant on that). Then there is the fact that the CPU usually starts work on the next instruction while the current instruction is processing IFF the register currently involved isnt involved in the next instruction (that would cause a lot of synchronisation problems). Now notice, that the CPU can't do any of that when manually entering and leaving. It can only start doing the mov eax, 1234 while performing the sub rsp, 0.
NOW: notice that the code on the right didn't take any precautions like making sure that the stack is big enough. If you sub too much stack at once, the stack will be exhausted, thats what we call a stack overflow. enter implements checks for that, and emits an interrupt if there is a SO (take this with a grain of salt, I couldn't find a resource backing this up). There are another type of checks I don't fully get (stack level checks) so I'd rather not make a fool of myself by writing about them.
Because of all those reasons I think that compilers should start using enter and leave again.
This post showed very well that bare numbers can often mislead.24
TLDR: crappy api + idiot ex client combo rant // devam si duška
I saw a lot of people bitching about APIs that don't return proper response codes and other stuff..
Well let me tell you a story. I used to work on a project where we had to do something like booking, but better..crossbreed with the Off&Away bidding site (which btw we had to rip off the .js stuff and reverse engineer the whole timer thingy), using free versions of everything..even though money wasn't an issue (what our client said). Same client decided to go with transhotel because it was sooooo gooood... OK? Why did noone heard of them then?
Anyhow, the api was xml based.. we had to send some xml that was validated against a schema, we received another that was supposed to be validated againts another schema.. and so on and so on..
The API docs were nonexistent.. What was there, was broken English or Spanish.. Even had some comments like Add This & that to chapter xy.. Of course that chapter didn't even exist yet. :( And the last documentation they had, was really really old..more than a year, with visible gaps, we got the validation schemas not even listed in the docs, let alone described properly.
Yaaay! And that was not everything.. besides wrong and missing data, the API itself caused the 500 server error whenever you were no longer authenticated.
Of course it didn't tell you that your session was dead.. Just pooof! Unhandled crap everywhere!
And the best part?! We handled that login after inspecting what the hell happened, but sent the notification to the company anyways.. We had a conf call, and sent numerous emails explaining to them what a 'try catch' is and how they should handle the not authenticated error <= BTW they should have had a handled xml response for that, we got the schema for it! But they didn't. Anyhow, after two agonizing days talking back and forth they at least set up the server to be available again after the horrified 500 error. Before, it even stopped responding until reset (don't ask me how they managed to do that).
Oh yeah, did I mention this was a worldwide renown company?! Where everybody spoke/wrote English?! Yup, they have more than 700 people there, of course they speak English! <= another one of my ex clients fabulous statements... making me wanna strangle him with his tie.. I told him I am not talking to them because no-one there understood/spoke English and it would be a waste of my time.. Guess who spent almost 3 hours to talk to someone who sounded like a stereotypical Indian support tech guy with a flue speaking Italian?! // no offence please for the referenced parties!!
So yeah, sadly I don't have SS of the fucked up documentation..and I cannot post more details (not sure if the NDA still holds even though they canceled the project).. Not that I care really.. not after I saw how the client would treat his customers..
Anywayz I found on the interwebz some proof that this shitty api existed..
picture + link: https://programmableweb.com/api/...
SubRant: the client was an idiot! Probably still is, but no longer my client..
Wanted to store the credit card info + cvc and owner info etc.. in our database.. for easier second payment, like on paypal (which he wanted me to totally customize the payment page of paypal, and if that wasn't possible to collect user data on our personalized payment page and then just send it over to paypal api, if possible in plaintext, he just didn't care as long as he got his personalized payment page) or sth.... I told the company owner that they are fucking retards if they think they can pull this off & that they will lose all their (potential) clients if they figure that out.. or god forbid someone hacked us and stole the data.. I think this shit is also against the law..
I think it goes without saying what happened next.. called him ignorant stupid fucktard to his face and told him I ain't doing that since our company didn't even had a certificate to store the last 4 numbers.. They heard my voice over the whole firm.. we had fish-tank like offices, so they could all see me yelling at the director..
Guess who got laid off due to not being needed anymore the next day?! It was the best day of my life..so far!! Never have I been happier to lose my job!!
P.S. all that crap + test + the whole backand for analysis, the whole crm + campaign emails etc.. the client wanted done in 6 months.. O.o
P.P.S. almost shat my pants when devRant notified my I cannot post and wanted to copy the message and then everything disappeard.. thank god I have written this in the n++ xD11
I'm intentionally resigning from my remote software development job to teach my company a lesson. The guy who wrote the codes previously really knew how to cook spaghetti 😀😂.
To add a single line takes minutes, because when you do something else breaks, and you'll keep fixing what breaks when you tried fixing what breaks when you try fixing what..... endless loop of bug-fix cycle.
Now they blame it on me.
They won't understand if they don't get someone new, my reputation will fix itself through that..
My first opinion after sighting the codes was, "re-write the whole project using better patterns and architecture", the reply as you can guess, we'll do that later.
I couldn't even upgrade the server to use even PHP 7.1 because the framework breaks, the guy has editted a lot from the vendors files. Don't ever try composer updates.
Two word to describes the situation. "It sucks".
The previous developer needs to be shot, literally.7
Lessons I've learnt so far on programming
-- Your best written code today can be your worst tomorrow (Focus more on optimisation than style).
-- Having zero knowledge of a language then watching video tutorials is like purchasing an arsenal before knowing what a gun is (Read the docs instead).
-- It's works on my machine! Yes, because you built on Lenovo G-force but never considered the testers running on Intel Pentium 0.001 (Always consider low end devices).
-- "Programming" is you telling a story and without adding "comments" you just wrote a whole novel having no punctuation marks (Always add comments, you will thank yourself later for it I promise).
-- In programming there is nothing like "done"! You only have "in progress" or "abandoned" (Deploy progressively).
-- If at this point you still don't know how to make an asynchronous call in your favourite language, then you are still a rookie! take that from me. (Asynchronous operation is a key feature in programming that every coder should know).
-- If it's more than two conditions use "Switch... case" else stick with "If... else" (Readability should never be under-rated).
-- Code editors can MAKE YOU and BREAK YOU. They have great impact on your coding style and delivery time (Choose editors wisely).
-- Always resist the temptation of writing the whole project from scratch unless needs be (Favor patching to re-creation).
-- Helper methods reduces code redundancy by a large chunk (Always have a class in your project with helper methods).
-- There is something called git (Always make backups).
-- If you don't feel the soothing joy that comes in fixing a bug then "programming" is a no-no (Coding is fun only when it works).
-- Get angry with the bugs not the testers they're only noble messengers (Bugs are your true enemy).
-- You would learn more than a lot reading the codes of others and I mean a lot! (Code review promotes optimisation and let's you know when you are writing macaroni).
-- If you can do it without a framework you have yourself a big fat plus (Frameworks make you entirely dependent).
-- Treat your code like your pet, stop taking care of it and it dies! (Codes are fragile and needs regular updates to stay relevant).

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
Learning that functions are objects really helped in restructuring a pile of my code. Eg passing it as a parameter to be executed.
Suddenly callback functions make a lot of sense now, and I've got a new found respect for the language.
Am i whiny or is resilience so glorified in this field?
I am a junior developer. I was assigned with two projects together with a friend and a senior. My friend and I finished our assigned tasks way before the deadline. Fast forward, my senior got reassigned to a different project since we are lacking with manpower. Naturally, his transactions were assigned to me and my friend. And my goodness, his existing codes are a piece of shit! It's all over the place. His variable naming is shit, his codes are all around the place, his codes doesn't even follow our company's coding standards, no try catch, a lot of unsafe practices. In short, cleaning his code is a pain in the ass and my friend and I got really busy with cleaning his mess. The testing of our system is really near but I just thought that maybe he's really busy with the other project that's why the quality of his codes deteriorated.
He's not. One day, I saw his in discord that he's playing during work hours lol. And the worse part is that he is playing with our boss! YES. DURING WORK HOURS. I got mad but I couldn't say anything because he is really tight with the boss.
Later on that day, we had our meeting. I was surprised when my boss told me that she's expecting that the excel part of our system is already finished. A little background here, my boss asked me to study Excel VB. However, I didnt get to study that much because I was so busy fixing bugs and after that came the cleaning of our senior's shit codes.
So I tried to say these things to my boss but I was cut out by the same senior shouting "You can do it!" over and over again. No one listened to what I was trying to say! And to make it even worse, the boss had a very proud look on her face and she even had the audacity to tell me that I'm lucky I have such a good support system. I dont.
Now, the company is planning to put me in a very demanding project. I havent finished cleaning up my senior's codes, I havent started anything with the excel and the deadline is next week!
The boss told me that even if I enter the other project, that I will still be responsible for the Excel part of our system. So fucking shoot me in the face.They were telling me that I should have a good time management system, that I should be flexible, that I should adapt easily, yada yada yada. She just makes you feel bad about yourself if you're not as 'flexible' as her.
The thing is, even if I have the best time management techniques in the world, if you bombard me with a shitload of tasks, then I won't be able to do it properly! I don't even take breaks anymore! I work literally 8 hours a day, even more than that. And I dont understand, why the hell is she overworking me when her friend (the senior dev) is just playing during work hours?
Another funniest thing is that she told us that when we encounter technical problems, we should ask our senior dev. Oh boy, if only she knows how shitty his codes are.6
Long long time ago when recharge coupons we a thing, I used to try out more codes in the series and waste my time. After failing a lot over this, I started trying out different USSD codes to see what other stuff is out there. This got me to stumble upon facebook and twitter on USSD. I'm not sure now but, twitter was probably *515# from my carrier.
Facebook. I remember chatting for quite a long period using this. Very slow and limited yet, fun. The USSD message expires within ~60secs. so you have to type the chat message before that or you lose everything you typed. The phone was no smartphone that would allow me to copy the text from the USSD input. On top of that panic, was a character limit to these messages. I remember hitting send while being midway through a message just so I don't lose what I typed, on a T-9 keyboard. Still miss those!
The person on the other side would receive a half message due to this, and would start replying without any patience, to which I panicked as now there's a new thing to respond to, and a half message which I'm waiting to complete.
Later over the weekend when I was allowed to visit the cyber cafe for an hour or two with 15-30 INR, reading the chat threads, being able to use the five sticker packs:) and thus continuing on a computer was fun. But, as the time at the cafe expires, I had to immediately shut off my session or I'd be charged more. Thus, I was left in the middle of a conversation again, and had to continue over USSD.
Using social media without any internet like this was quite fun in a weird way. If I get a new message, I'd get a USSD alert, and then an sms if I didn't reply in some 10-15mins!
This had all the features like like and comment. Friend requests too. For the posts in a "timeline" which was new and fancy in those days, all you see is the caption of a post which also gets truncated quite a bit as USSD also has to show it's options like:
3. Next Post
4. Main Menu
This was around '13 or '14 I guess. After which I later got my first computer- a laptop. Anyways, the tactile feel of pressing the buttons on a T-9 keypad is nostalgic to me. 😅 And if you were a pro at texting, u must hv used shrtcts lyk dis too w/ emojis lyk :-) <3
I'm in a programming school that gives only projects in C and a method to learn quickly.
Then we don't have official web classes or anything so we have "Labs" or "Clubs" and last time I was at a web programming club, leaded by students (because it gives me some more credits).
And their explications about server-side and client-side codes were not clear (and obviously not exhaustive).
I have some (not a lot neither) experience in web programming so I helped him to make his course more understandable but I can't believe that these courses are given by students who don't have any idea of what's web programming...3
hey guys yesterday I got roasted cuz I was using a pc instead of Mac for development work and this was my reply. For me I don't gonna spend 2000+ $ only for 1 sec faster app loading and only for writing codes if someone willing to spend lot of money then they have completely command on there system Mac is very overpriced and overprotective it doest allow dual boot tell u what Mac sucks in 4k video editing,games,it don't even support maya or 3ds max rendering on Mac is gonna hit you hard , and there is same for linux but because it's free I don't much care about it but it is extremely crash and error prone I've installed Ubuntu nearly 20+ computer and after few days some kind of internal error occurred if u cancelled any ongoing installation it's going to hijack your system not let order program to install unless you manually clean that shit out ,yea Unix systems have bit faster app opening time and I appreciate that .
For nerds like me it's not only about coding stuff I like to do crazy stuffs17
I never thought that this day will come, be here is my first rant with a big dose of frustration.
So, I'm working on the API team of one of ower products and a coworker that works on the webapp has a lot of problems (don't want to be mean, but he has problems like 'i can't catch a 404 http status, please send a 200 with a message' ) and he always go and wines about the API and that he can't do his job because the API is faulty...
But it is not the case, every functionality of the API is well tested and it works as it should.
So, tonight I was the only one left from my team and the project manager comes and
starts asking me about why I am returning http status codes with all my responses, how the login works and other stuff like that...
Just wasted more than an hour to prove that all the code that I wrote works as expected...1
Went through a lot of GitHub repositories and other people's codes to try to understand how the "magic" happens. Slowly started getting a hang of it. Good thing being, I picked up good coding practices along the way
Back when I was doing my uni final year project. i was given the choice of either writing codes or writing documentation (graphs, requirement and a whole lot of other madeup bullshit)
I deicide go with coding, sign up with laracast. watch a whole lot of screen cast. and BOOM, coding is easy - I was literally quoting bombastic technical terms like many-to-many relationship to my group mates after 2 videos. (didn't even know what was bootstrap at that time) Thats was when I decide I wanna code for a living. Laravel made me a developer.1
How do you approach generating "random" unique numbers/strings ? Exactly, when you have to be sure the generated stuff is unique overtime? Eg. as few collisions in future as possible.
Now I don't mean UUIDs but when there is a functionality that needs some length defined, symbol specific and definitely unique data, every time it does it's stuff.
TLDR STORY: Generating 8 digits long numbers so they are (deterministically - wink wink) unique is hard but Format Preserving Encryption saves the day. (for me)
I had to deal with both strings and codes today.
One was to generate shortlink word for url, luckily found a library that does exactly this. (Hashids)
BUT generating 8 digits long, somewhat random number was harder then I thought, found out on SO something like "sha256(seed) => bytes => ascii/numbers mangling" but that had a lot of collisions because of how the hash got mangled to actually output numbers and also to fit the length.
After some hours I stumbled upon Format Preserving encryption (pyffx) and man it did what I wanted and it had max 2 collisions in 100k values. Still the solution with this feels hacky af. (encrypting straddled unix timestamp with lots of decimals)6
Two (2) senior developers and one (1) senior tester left our team and I am left with two (2) Java legacy applications that are hard to maintain. Here is a list of things I hate about these old webapps (let's call them app A and B):
1. App A depends on 80% web services. If one web service for a product or warehouse goes down, work flow is impeded while prod support team checks with the core services team for repair
2. App B is a maven project with multiple modules dependent on libraries that are dependent on company's internal libraries. So if we want to upgrade to OpenJdk 9 and up, the project will definitely produce a lot of errors due to deprecated/unsupported codes
3. App A is dependent on Tibco and I have no experience on that
4. App B's continuous integration build tool is Jenkins and the jobs that build it has a shell script that wasn't updated during the tech upgrade enhancement. The previous developer who did the knowledge transfer to me didn't tell me about this (it should be considered a defect on her part but she already resigned)
5. App A when loaded in eclipse IDE is a pain to work with since it is only allowed to build a war file using ant. I have to lookup in quick search instead of calling shortcuts (call hierarchy) because the project wasn't compiled via eclipse.
6. It's impossible to debug app A because of #5
7. Both applications have high priority and complex enhancements and I have no other teammates to help me
8. You never know what else can go wrong anytime1
Some of you know I'm an amateur programmer (ok, you all do). But recently I decided I'm gonna go for a career in it.
I thought projects to demo what I know were important, but everything I've seen so far says otherwise. Seems like the most important thing to hiring managers is knowing how to solve small, arbitrary problems. Specifics can be learned and a lot of 'requirements' are actually optional to scare off wannabes and tryhards looking for a sweet paycheck.
So I've gone back, dusted off all the areas where I'm rusty (curse you regex!), and am relearning, properly. Flash cards and all. Getting the essentials committed to memory, instead of fumbling through, and having to look at docs every five minutes to remember how to do something because I switch languages, frameworks, and tooling so often. Really committing toward one set of technologies and drilling the fundamentals.
Would you say this is the correct approach to gaining a position in 2020, for a junior dev?
I know for a long time, 'entry level' positions didn't really exist, but from what I'm hearing around the net, thats changing.
Heres what I'm learning (or relearning since I've used em only occasionally):
* Git (small personal projects, only used it a few times)
* Backend (Flask, Django)
* Frontend (React)
* Testing with Cypress or Jest
Any of you have further recommendations?
Gulp? Grunt? Are these considered 'matter of course' (simply expected), or learn-as-you for a beginner like myself?
Is knowing the agile 'manifesto' (whatever that means) by heart really considered a big deal?
What about the basics of BDD and XP?
Is knowing how to properly write user-stories worth a damn or considered a waste of time to managers?
Am I going to be tested on obscure minutiae like little-used yarn/npm commands?
Would it be considered a bonus to have all the various HTTP codes memorized? I mean thats probably a great idea, but is that an absolute requirement for newbies, or something you learn as you practice?
During interviews, is there an emphasis on speed or correctness? I'm nitpicky, like to write cleanly commented code, and prefer to have documentation open at all times.
Am I going to, eh, 'lose points' for relying on documentation during an interview?
I'm an average programmer on my good days, and the only thing I really have going for me is a *weird* combination of ADD and autism-like focus that basically neutralize each other. The only other skill I have is talking at people's own level to gauge what they need and understand. Unfortunately, and contrary to the grifter persona I present for lulz, I hate selling, let alone grifting.
Otherwise I would have enjoyed telemarketing way more and wouldn't even be asking this question. But thankfully I escaped that hell and am now here, asking for your timeless nuggets of bitter wisdom.
What are truly *entry level* web developers *expected* to know, *right out the gate*, obviously besides the language they're using?
Also, what is the language they use to program websites? It's like java right? I need to know. I'm in an interview RIGHT now and they left me alone with a PC for 30 minutes. I've been surfing pornhub for the last 25 minutes. I figure the answer should take about 5 minutes, could you help me out and copypasta it?
Okay, okay, I'm kidding, I couldn't help myself. The rest of the questions are serious and I'd love to know what your opinions are on what is important for web developers in 2020, especially entry level developers.7
So, funny story with a bit of self promotion at the end.
I was recently checking out some apps on playstore and found that my first ever , "launched just to experiment" app (released 1.5 years ago) has received more than 5k downloads . I was very happy about that so posted a small message on LinkedIn .
Now , my LinkedIn profile consists of 98% people who are totally strangers and never met me ( is it just me or do you also get a lot of stranger connect requests there?). So my usual post rarely ever goes beyond 5 or 6 likes.
Bit idk how there too my post got 35+ likes and now i was on cloud9.
So i finally decided to kick my ass and release some update to that app ( it had around 70% pity comments like "nice first app,but it should have this x feature",. "overall nice but it could use an x feature " etc.
And boy what my journey was in the last 72hours.
Firstly my madhead laptop started killing me with the battery failures and constant hang.
Then my past asshole self tried to give me a middle finger. So i have this whole partition in my memory where i keep my Android stuff and apps. It has a special folder named published zone and i keep all my published app codes and related files there.
I was fairly certain that this app's code eill be also there,so i opened it, found the code and tried running it.
Turns out my asshole self had tried to mess around the code so much that all the db layer WAS fucked up, all the ui WAS changed and no code was working.
"Not to worry", i thought. I always use git and there would be a correct version some commits before. WRONG. I HAD CHANGED THE WHOLE FUCKING WORKING PRODUCTION CODE AND DIDN'T MAINTAIN A VCS!
Also this was the verbose and shitty java code my 1.5 year before self so loved to write, so it was taking me way more time to figure out what's happening in an already fucked up code.
So i tried a couple of ways to get back my working code :
- I tried looking for a google recommended solution. Those guys take my whole app code build and distribute via playstore, but they provide no means to retrieve back the original code.
- i checked my (occasionally) back up hard disk but no. My hard disk would have 100s of movies from 2016 , but not a useful piece of fuckin code.
- i also tried to get my apk and decompile it via some online decompiler. Here the google again fucks up and don't allow me to get my apk directly. Meanwhile i found a ton of shady websites which are hosting an apk of my app without my knowledge O_o . I tried to decompile on of them but code was even more non understandable than my fuck up code.
So i ended up looking at both the mess up code and decompiled code and coded the whole app from scratch ( well not scratch, i extracted the resources and some undamaged activities from the mess up code . Also github was down for more than 3 hours yesterday , at the same time when i was trying to look onto some repositories)
- DON'T FUCK UP WITH THE PRODUCTION CODE
- MAINTAIN VCS
- Your laptop is shit reliable, github is also shit reliable , so save code at multiple places.
- there are way more copies of your code lying on the internet than you think.
Checkout my app here :https://play.google.com/store/apps/...3
I do a lot of linguistic side projects, and got tired of rebuilding the languages table, so I did a bit of looking around today and put together a MySQL table dump with all of the the codes from ISO 639-1, 2, and 3.
If anyone's interested, here's the link. Enjoy!
How long does it take to start writing codes without having to do “too much” looking up of some context?
I’m quite at the intermediate level and I fear I do a lot of cramming(and pouring) than actual coding.
I want to code all on my own, or at least tons of lines before having to check something up.
How do you guys do it? How do I become ‘pro’?6
I'm just testing out some code for Spring Boot with Spring web. Whilst inspecting Spring's HttpStatus enum I suddenly realized there are a lot more HTTP status codes than I had estimated. I knew there were many, but woah that's a lot.
On a side note, it really helps to debug work stuff at home. More concentration, more time and such.
Think you've mastered abstraction /seperation of what should be Android classes versus what should be Android resources?
Decompile the Gmail app and check all the xml tags you might have missed.
Remember: UI and most application properties are loaded on the xml codes first (during inflation), then on activities or fragments last (especially if the views are only instantiated).
I just realized that I need to learn a lot of tags today.
So I wanted to make a Commodore 64 game, and I decided to use cc65, since I don’t want to use assembly.
First, I tried to position text, and I tried to use CSI escape codes, but that didn’t work.
I forgot to look at the examples, and then saw a lot of helper functions, which were nice.
Next, I tried to do some timing. sleep can only do seconds, so I wanted to use usleep, but they didn’t port it...
Moral of the story: ~~look at the docs~~ don’t make C64 games
Critical Tips to Learn Programming Faster Sample:
Be comfortable with basics
The mistake which many aspiring students make is to start in a rush and skip the basics of programming and its fundamentals. They tend to start from the comparatively advanced topics.
This tends to work in many sectors and fields of Technology, but in the world of programming, having a deep knowledge of the basic principles of coding and programming is a must. If you are taking a class through a tutor and you feel that they are going too fast for your understanding, you need to be firm and clear and tell them to go slowly, so that you can also be on the same page like everyone else
Most often than not, many people tend to struggle when they reach a higher level with a feeling of getting lost, then they feel the need to fall back and go through basics, which is time-consuming. Learning basics well is the key to be fast and accurate in programming.
Practice to code by hand.
This may sound strange to some of you. Why write a code by hand when the actual work is supposed to be done on a computer? There are some reasons for this.
One reason being, when you were to be called for an interview for a programming job, the technical evaluation will include a hand-coding round to assess your programming skills. It makes sense as experts have researched and found that coding by hand is the best way to learn how to program.
Be brave and fiddle with codes
Most of us try to stick to the line of instructions given to us by our seniors, but it is extremely important to think out of the box and fiddle around with codes. That way, you will learn how the results get altered with the changes in the code.
Don't be over-ambitious and change the whole code. It takes experience to reach that level. This will give you enormous confidence in your skillset
Reach out for guidance
Seeking help from professionals is never looked down upon. Your fellow mates will likely not feel a hitch while sharing their knowledge with you. They also have been in your position at some point in their career and help will be forthcoming.
You may need professional help in understanding the program, bugs in the program and how to debug it. Sometimes other people can identify the bug instantly, which may have escaped your attention. Don't be shy and think that they'll make of you. It's always a team effort. Be comfortable around your colleagues.
You must have seen people burning the midnight oil and not coming to a conclusion, hence being reported by the testing team or the client.
These are common occurrences in the IT Industry. It is really important to conserve energy and take regular breaks while learning or working. It improves concentration and may help you see solutions faster. It's a proven fact that taking a break while working helps with better results and productivity. To be a better programmer, you need to be well rested and have an active mind.
It's a common misconception that learning how to program will take a lot of money, which is not true. There are plenty of online college courses designed for beginner students and programmers. Many free courses are also available online to help you become a better programmer. Websites like Udemy and programming hub is beneficial if you want to improve your skills.
There are free courses available for everything from [HTML](https://bitdegree.org/learn/...) to CSS. You can use these free courses to get a piece of good basic knowledge. After cementing your skills, you can go for complex paid courses.
Read Relevant Material
One should never stop acquiring knowledge. This could be an extension of the last point, but it is in a different context. The idea is to boost your knowledge about the domain you're working on.
In real-life situations, the client for which you're writing a program for possesses complete knowledge of their business, how it works, but they don't know how to write a code for some specific program and vice versa.
So, it is crucial to keep yourself updated about the recent trends and advancements. It is beneficial to know about the business for which you're working. Read relevant material online, read books and articles to keep yourself up-to-date.
Never stop practicing
The saying “practice makes perfect” holds no matter what profession you are in. One should never stop practicing, it's a path to success. In programming, it gets even more critical to practice, since your exposure to programming starts with books and courses you take. Real work is done hands-on, you must spend time writing codes by hand and practicing them on your system to get familiar with the interface and workflow.
Search for mock projects online or make your model projects to practice coding and attentively commit to it. Things will start to come in the structure after some time.4
So as a personal project for work I decided to start data logging facility variables, it's something that we might need to pickup at some point in the future so decided to take the initiative since I'm the new guy.
I setup some basic current loop sensors are things like gas line pressures for bulk nitrogen and compressed air but decided to go with a more advanced system for logging the temperature and humidity in the labs. These sensors come with 'software' it's a web site you host internally. Cool so I just need to build a simple web server to run these PoE sensors. No big deal right, it's just an IIS service. Months after ordering Server 2019 though SSC I get 4 activation codes 2 MAK and 2 KMS. I won the lottery now i just have to download the server 2019 retail ISO and... Won't take the keys. Back to purchasing, "oh I can download that for you, what key is yours". Um... I dunno you sent me 4 Can I just get the link, "well you have to have a login". Ok what building are you in I'll drive over with a USB key (hoping there on the same campus), "the download keeps stopping, I'll contact the IT service in your building". a week later I get an install ISO and still no one knows that key is mine. Local IT service suggests it's probably a MAK key since I originally got a quote for a retail copy and we don't run a KMS server on the network I'm using for testing. We'll doesn't windows reject all 4 keys then proceed to register with a non-existent KMS server on the network I'm using for testing. Great so now this server that is supposed to connected to a private network for the sensors and use the second NIC for an internet connection has to be connected to the old network that I'm using for testing because that's where the KMS server seems to be. Ok no big deal the old network has internet except the powers that be want to migrate everything to the new more secure network but I still need to be connected to the KMS server because they sent me the wrong key. So I'm up to three network cards and some of my basic sensors are running on yet another network and I want to migrate the management software to this hardware to have all my data logging in one system. I had to label the Ethernet ports so I could hand over the hardware for certification and security scans.
So at this point I have my system running with a couple sensors setup with static IP's because I haven't had time to setup the DNS for the private network the sensors run on. Local IT goes to install McAfee and can't because it isn't compatible with anything after 1809 or later, I get a message back that " we only support up to 1709" I point out that it's server 2019, "Oh yeah, let me ask about that" a bunch of back and forth ensues and finally Local IT get's a version of McAfee that will install, runs security scan again i get a message back. " There are two high risk issues on your server", my blood pressure is getting high as well. The risks there looking at McAfee versions are out of date and windows Defender is disabled (because of McAfee).
There's a low risk issue as well, something relating to the DNS service I didn't fully setup. I tell local IT just disable it for now, then think we'll heck I'll remote in and do it. Nope can't remote into my server, oh they renamed it well that's lot going to stay that way but whatever oh here's the IP they assigned it, nope cant remote in no privileges. Ok so I run up three flights of stairs to local IT before they leave for the day log into my server yup RDP is enabled, odd but whatever let's delete the DNS role for now, nope you don't have admin privileges. Now I'm really getting displeased, I can;t have admin privileges on the network you want me to use to support the service on a system you can't support and I'm supposed to believe you can migrate the life safety systems you want us to move. I'm using my system to prove that the 2FA system works, at this rate I'm going to have 2FA access to a completely worthless broken system in a few years. good thing I rebuilt the whole server in a VM I'm planning to deploy before I get the official one back. I'm skipping a lot of the ridiculous back and forth conversations because the more I think about it the more irritated I get.1
YAYYY! I MADE IT!!
After several nights of playing with my new and very first custom mechanical keyboard, at last I could successfully get my long-time-dreaming keyboard!
I read the guilds, tutorials, even youtube videos to get walked through the process:
- I started with building my own layout on different websites, since they said that it would be easier to use online tools than to write codes by yourself in order to build your own keymappings, but the UI/UX of the first one I tried was so bad that it took me a great deal of time to understand how to use it and working on it is even more time consuming. Later I found another webpage which was less recommended, but could help me to do that a lot easier.
- Then, the result was compiled to a firmware file, which would be flashed into the kb's controller. Loading the file into the board was also tiring and got me exhausted totally! I tried all the "lazy" recommended ways (using Windows softwares) but received the same error all the time. When I almost lost all the hopes, I'd come to the least recommended way: typing a few command lines on Linux. And it worked! The keyboard just do what I want it to do miraculously.
What I learnt: never do complicated things on Windows, because they are suuuuuper simple on Linux!
P/S: Sorry for the bad lighting in my room and the tiny spacebar (the spacebar size is 7u which I don't have one right now). I just need a beautiful keycap set to make it perfect.5
