So, you start with a PHP website.
Nah, no hating on PHP here, this is not about language design or performance or strict type systems...
This is about architecture.
No backend web framework, just "plain PHP".
Well, I can deal with that. As long as there is some consistency, I wouldn't even mind maintaining a PHP4 site with Y2K-era HTML4 and zero Javascript.
That sounds like fucking paradise to me right now. 😍
But no, of course it was updated to PHP7, using Laravel, and a main.js file was created. GREAT.... right? Yes. Sure. Totally cool. Gotta stay with the times. But there's still remnants of that ancient framework-less website underneath. So we enter an era of Laravel + Blade templates, with a little sprinkle of raw imported PHP files here and there.
Fine. Ancient PHP + Laravel + Blade + main.js + bootstrap.css. Whatever. I can still handle this. 🤨
But then the Frontend hipsters swoosh back their shawls, sip from their caramel lattes, and start whining: "We want React! We want SPA! No more BootstrapCSS, we're going to launch our own suite of SASS styles! IT'S BETTER".
OK, so we create REST endpoints, and the little monkeys who spend their time animating spinners to cover up all the XHR fuckups are satisfied. But they only care about the top most visited pages, so we ALSO need to keep our Blade templated HTML. We now have about 200 SPA/REST routes, and about 350 classic PHP/Blade pages.
So we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + React + SPA 😑
Now the Backend grizzlies wake from their hibernation, growling: We have nearly 25 million lines of PHP! Monoliths are evil! Did you know Netflix uses microservices? If we break everything into tiny chunks of code, all our problems will be solved! Let's use DDD! Let's use messaging pipelines! Let's use caching! Let's use big data! Let's use search indexes!... Good right? Sure. Whatever.
OK, so we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + React + SPA + Redis + RabbitMQ + Cassandra + Elastic 😫
Our monolith starts pooping out little microservices. Some polished pieces turn into pretty little gems... but the obese monolith keeps swelling as well, while simultaneously pooping out more and more little ugly turds at an ever faster rate.
Management rushes in: "Forget about frontend and microservices! We need a desktop app! We need mobile apps! I read in a magazine that the era of the web is over!"
OK, so we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + GraphQL + React + SPA + Redis + RabbitMQ + Google pub/sub + Neo4J + Cassandra + Elastic + UWP + Android + iOS 😠
"Do you have a monolith or microservices" -- "Yes"
"Which database do you use" -- "Yes"
"Which API standard do you follow" -- "Yes"
"Do you use a CI/building service?" -- "Yes, 3"
"Which Laravel version do you use?" -- "Nine" -- "What, Laravel 9, that isn't even out yet?" -- "No, nine different versions, depends on the services"
"Besides PHP, do you use any Python, Ruby, NodeJS, C#, Golang, or Java?" -- "Not OR, AND. So that's a yes. And bash. Oh and Perl. Oh... and a bit of LUA I think?"
2% of pages are still served by raw, framework-less PHP.32 -
Although I love developing I always thought that there was something missing.
I learned Java but didn't really like it. I had spent quite some time with web development and enjoyed it but I felt like developing with JavaScript was too high level and I felt the same for Python.
So I started learning the most awesome programming language: C
I just love that I have so much control over everything and that the language is so compact and gives you just the right amount of tools you need.
I also love physics and electronics a lot and it feels awesome to first build something and then program it.
I am looking forward to design a PCB (printed circuit board) and write code for an AVR microcontroller like the Atmega328 (most arduinos use this one).
Picture of the project I am working on.10 -
Hold your keyboard! Hold your mouse!
Sons of Java, of Python, my brothers,
I see in your eyes the same fear that would take the heart of me.
A day may come when the sense of programming language fails,
when we forsake our logic
and break all the laws of programming,
but it is not this day.
An hour of headache and shattered monitors,
when the age of Javascript rises,
but it is not this day!
This day we will find solutions on StackOverflow!!
By all that you hold dear on this good code,
I bid you stand,
Developers!!!8 -
Hello there, just couple of words about PHP. I've been develop on PHP more than 10 years, I've seen it all 3,4,5,{6},7. Yes PHP was not good in terms of engineering and patterns, but it was simple, it was the most simple language for web to start those days. It was simple as you put code into file, upload it via FTP and it works. No java servlets, no unix consoles, no nothing, just shared hosting account was enough to host site, or even application with database. As database everybody used to have mysql, again because its simple to start and easy to maintain. So PHP+MySQL became industry standard on Web during 00-2012, and continues in some way.
You can write HTML and logic inside single file, within php code, even more single file may content few pages, or even kind of framework. That simplicity and agility sticks everybody who wants to develop sites with PHP.
This is pretty much about why it is so popular.
Each good or wannabe PHP developer in an early days write its own framework or library (like in javascript this days because of nodejs)
Imagine that PHP has hadn't have package manager, developers used to have host packages on their own sites, then various packages catalog sites created, and then finally composer. A gazillions of php code had spread over internet, without any kind of dependency control. To include libraries to your projects you have to just write include, or require. Some developers do it better than others.
So what we have ? A lots of code, no repositories, zip archives with libraries, no dependency control.
Project that uses that kind of code are still alive even today, they are solid hose of cards, and unmaintainable of course.
And main question that I'm trying to answer is Why PHP is not good ?
- First is amount of legacy code which people copy and pasted into their project, spread it even more like a virus.
- Lack of industry standards at the beginning lead to a lots of bad practices among developers. PHP code usually smells.
open source php projects in early days was developed in same conditions so even in phpbb, phpnuke, wordpress, drupal used to have a lot of bad practices in their codebase. So php developers usually not study by another library, instead they write their own frameworks/libraries.
- "It works", - there are no strong business demands, on web development, again because lack of standards, and concerns.
This three things are basically same, they linked to each other and summarize of answer of why PHP have strong smells and everybody yelling against it.
Whats is with PHP nowadays ? Of course PHP today is more influenced by good practice of webdev. Composer, Zend, Laravel, Yii, Symphony and language it self became more adult so to say, but developers...
People who never tried anything except PHP are usually weaker in programming and ecosystem knowledge than people who tried something else, python, perl, ruby, c for instance.
Summary
PHP as any other programming language is a tool. Each tool has its own task. Consider this and your task requirements and PHP can be just good enough solution.
"PHP is shit" - usually you heard that from people who never write strong applications on PHP and haven't used any good tools like Symphony or Laravel.
Cheap developers, - the bigger community, the more chance to hire cheap developers, and more chance to get bad code. That can be applied on any other language.
PHP has professionals developers, usually they have not only php on scope.
That's all folks, this is very brief, I am not covering php usage early days in details, but this is good enough to understand the point.
Enjoy.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 -
Let the student use their own laptops. Even buy them one instead of having computers on site that no one uses for coding but only for some multiple choice tests and to browse Facebook.
Teach them 10 finger typing. (Don't be too strict and allow for personal preferences.)
Teach them text navigation and editing shortcuts. They should be able to scroll per page, jump to the beginning or end of the line or jump word by word. (I am not talking vi bindings or emacs magic.) And no, key repeat is an antifeature.
Teach them VCS before their first group assignment. Let's be honest, VCS means git nowadays. Yet teach them git != GitHub.
Teach git through the command line. They are allowed to use a gui once they aren't afraid to resolve a merge conflict or to rebase their feature branch against master. Just committing and pushing is not enough.
Teach them test-driven development ASAP. You can even give them assignments with a codebase of failing tests and their job is to make them pass in the beginning. Later require them to write tests themselves.
Don't teach the language, teach concepts. (No, if else and for loops aren't concepts you god-damn amateur! That's just syntax!)
When teaching object oriented programming, I'd smack you if do inane examples with vehicles, cars, bikes and a Mercedes Benz. Or animal, cat and dog for that matter. (I came from a self-taught imperative background. Those examples obfuscate more than they help.) Also, inheritance is overrated in oop teachings.
Functional programming concepts should be taught earlier as its concepts of avoiding side effects and pure functions can benefit even oop code bases. (Also great way to introduce testing, as pure functions take certain inputs and produce one output.)
Focus on one language in the beginning, it need not be Java, but don't confuse students with Java, Python and Ruby in their first year. (Bonus point if the language supports both oop and functional programming.)
And for the love of gawd: let them have a strictly typed language. Why would you teach with JavaScript!?
Use industry standards. Notepad, atom and eclipse might be open source and free; yet JetBrains community editions still best them.
For grades, don't your dare demand for them to write code on paper. (Pseudocode is fine.)
Don't let your students play compiler in their heads. It's not their job to know exactly what exception will be thrown by your contrived example. That's the compilers job to complain about. Rather teach them how to find solutions to these errors.
Teach them advanced google searches.
Teach them how to write a issue for a library on GitHub and similar sites.
Teach them how to ask a good stackoverflow question :>6 -
TL;DR :
"when i die i want my group project members to lower me into my grave so they can let me down one last time"
STORY TIME
Last year in College, I had two simultaneous projects. Both were semester long projects. One was for a database class an another was for a software engineering class.
As you can guess, the focus of the projects was very different. Databases we made some desktop networked chat application with a user login system and what not in Java. SE we made an app store with an approval system and admin panels and ratings and reviews and all that jazz in Meteor.js.
The DB project we had 4 total people and one of them was someone we'll call Frank. Frank was also in my SE project group. Frank disappeared for several weeks. Not in class, didn't contact us, and at one point the professors didn't know much either. As soon as we noticed it would be an issue, we talked to the professors. Just keeping them in the loop will save you a lot of trouble down the road. I'm assuming there was some medical or family emergency because the professors were very understanding with him once he started coming back to class and they had a chance to talk.
Lesson 1: If you have that guy that doesn't show up or communicate, don't be a jerk to them and communicate with your professor. Also, don't stop trying to contact the rogue partner. Maybe they'll come around sometime.
It sucked to lose 25% of our team for a project, but Frank appreciated that we didn't totally ignore him and throw him under the bus to the point that the last day of class he came up to me and said, "hey, open your book bag and bring it next to mine." He then threw a LARGE bottle of booze in there as a thank you.
Lesson 2: Treat humans as humans. Things go wrong and understanding that will get you a lot farther with people than trying to make them feel terrible about something that may have been out of their control.
Our DB project went really well. We got an A, we demoed, it worked, it was cool. The biggest problem is I was the only person that had taken a networking class so I ended up doing a large portion of the work. I wish I had taken other people's skills into account when we were deciding on a project. Especially because the only requirement was that it needed to have a minimum of 5 tables and we had to use some SQL language (aka, we couldn't use no-SQL).
The SE project had Frank and a music major who wanted to minor in CS (and then 3 other regular CS students aside from me). This assignment was make an app store using any technology you want. But, you had to use agile sprints. So we had weekly meetings with the "customer" (the TA), who would change requirements on us to keep us on our toes and tell us what they wanted done as a priority for the next meeting. Seriously, just like real life. It was so much fun trying to stay ahead of that.
So we met up and tried to decided what to use. One kid said Java because we all had it for school. The big issue is trying to make a Java web app is a pain in the ass. Seriously, there are so many better things to use. Other teams decided to use Django because they all wanted to learn Python. I suggested why not use something with a nice package system to minimize duplicating work that had already been done and tested by someone. Kid 1 didn't like that because he said in the real world you have to make your own software and not use packages. Little did he know that I had worked in SE for a few years already and knew damn well that every good project has code from somewhere else that has already solved a problem you're facing. We went with Java the first week. It failed miserably. Nobody could get the server set up on their computers. Using VCS with it required you to keep the repo outside of the where you wrote code and copy and paste changes in there. It was just a huge flop so everyone else voted to change.
Lesson 3: Be flexible. Be open to learning new things. Don't be afraid to try something new. It'll make you a better developer in the long run.
So we ended up using Meteor. Why? We all figured we could pick up javascript super easy.Two of us already knew it. And the real time thing would make for some cool effects when an app got a approved or a comment was made. We got to work and the one kid was still pissed. I just checked the repo and the only thing he committed was fixing the spelling of on word in the readme.
We sat down one day and worked for 4 straight hours. We finished the whole project in that time. While other teams were figuring out how to layout their homepage, we had a working user system and admin page and everything. Our TA was trying to throw us for loops by asking for crazy things and we still came through. We had tests that ran along side the application as you used it. It was friggin cool.
Lesson 4: If possible, pick the right tool for the job. Not the tool you know. Everything in CS has a purpose. If you use it for its purpose, you will save days off of a project.1 -
So I'm in HS CS and some of us know how to code, and the others are struggling with variables (in python).
One of them asks: "Sir, why are doing python? I heard about java and how it changed the internet and stuff"
So naturally my teacher explains the difference (between JS and Java, in case your captain of the USS dumbass), but then described JS in the best way possible:
"JavaScript is basically the California of programming, its a really weird place where people mix everything up and nothing makes sense"4 -
What is considered best practice for code indentation? When I'm working with HTML and Javascript my rule of thumb is 2 spaces for indentation, and with Java and Python it's 4 spaces.
Also I'm trying to break my bad habit of mixing tabs and spaces. It's messing with the laws of physics.12 -
C : Cool (for me)
Java : Just A Variety Available (uhm.. no hard feelings java lovers)
Python : Please .. You THink On Nothing (You literally think on nothing xD )
JavaScript : Join A Very Attractive , Sophisticated Code , Reactive In Particular Time (hmm...that took a lotta time)9 -

There is something so comfy about Java that I never get from other languages.
I don't know why but I genuinely enjoy writing 200 lines of boilerplate code. Maybe it makes me feel I am in control and not some syntactic magic like in Python or Javascript.
People keep ranting on java, yet it lives on.2 -
So apparently hiring these days is all about 1/3 learning random questions and answers 1/3 remembering algorithms from code execution portals 1/3 luck. Well fuck my life, it’s worse then 5 years ago when I last switched jobs.
So how was it 5 years ago you ask ?
I send my cv with exposed java interviewed for javascript and hired for python. At least then it was 50/50 luck.5 -
I'm really not sure. When I was 7-8 years old, I liked to view source in IE, then I somehow managed to use Javascript in the browser. First only some dumb opening of windows. And I liked Batch, so I made some files for copying, backup and stuff.
Then I got to PHP during the years from some online tutorial about making dynamic websites. My website was more static than stone, but yeah, I did page loading with PHP! Awful experience anyway, because I had to install Xampp, get it work and other stuff. 11 years old or so. (and I used Xampp only as a fileserver between laptop and desktop later, because.. PHP4... just no.)
As 12 years old or so I experienced my first World of Warcraft (vanilla) on a custom server in an internet cafe and I thought it's a singleplayer game. When I found out that no, I googled how to make my own server (hated multiplayer back then and loved good games with huge storylines). Failed miserably with ManGOS, got something to work with ArcEMU. There I learned some C++ basic stuff, which I hoped would helped me to fix some bugs. When I opened the code I was like: "Suuure." and left it like that. I learned what a MySQL database is, broke it like four times when I forgot WHERE and still rather played with websites i.e. html, css, js and optionally php when I wanted to repair a webpage for the server. With a friend we managed to get the server work via Hamachi, was fun, the server died too soon. Then I got ManGOS to work, but there wasn't really any interest to make a server anymore, just singleplayer for the lore. (big warcraft fan, don't kick me :D )
I think it was when I was 13y.o. I went to Delphi/Pascal course, which I liked a lot from the beginning, even managed to use my code on old Knoppix via Lazarus(Pascal). At this age I really liked thoae Flash games which were still common to see everywhere. So I downloaded .swfs, opened and tried to understand it. Managed to pull some stuff from it and rewrite in Pascal. Nope, never again that crap.
About the same time I got to Flash files I discovered Java. It was kind of popular back then, so I thought let's give it a try. I liked Flash more. Seriously. I've never seen so much repetitiveness and stupid styling of a code. I had either IDE for compiling C++ or Pascal or notepad! You think I wanted my code kicked all over the place in multiple folders and files? No.
So back to Pascal. I made some apps for my old hobby, was quite satisfied with the result (quiz like app), but it still wasn't the thing. And I really thought I'd like to study CS.
I started to love PHP because of phpBB forums I worked on as 15 y.o. I guess. At the same time I think there was an optional subject at school, again with Pascal. I hated the subject, teacher spoke some kind of gibberish I didn't really understand back then at all and now I find it only as a really stupid explanation of loops and strings.
So I started to hate Pascal subject, but not really the lang itself. Still I wanted something simpler and more portable. Then I got to Python as hm, 17y.o. I think and at the same time to C++ with DevC++. That was time when I was still deciding which lang to choose as my main one (still playing with website, database and js).
Then I decided that learning language from some teacher in a class seriously pisses me off and I don't want to experience it again. I choose Python, but still made some little scripts in C++, which is funny, because Python was considered only as a scripting lang back then.
I haven't really find a cross-platform framework for C++, which would: a) be easy to install b) not require VisualStudio PayForMe 20xy c) have nice license if I managed to make something nice and distribute it. I found Unity3D though, so I played with Blender for models, Audacity for music and C# for code. Only beautiful memories with Unity. I still haven't thought I'm a programmer back then.
For Python however I found Kivy and I was playing with it on a phone for about a year. Still I haven't really know what to do back then, so I thought... I like math, numbers, coding, but I want to avoid studying physics. Economics here I go!
Now I'm in my third year at Uni, should be writing thesis, study hard and what I do? Code like never before, contribute, work on a 3D tutorial and play with Blender. Still I don't really think about myself as a programmer, rather hobby-coder.
So, to answer the question: how did I learn to program? Bashing to shit until it behaved like I desired i.e. try-fail learning. I wouldn't choose a different path.2 -
As my friend @AlexDeLarge found my last rant less detailed and idiotic so I deleted that rant and am writing this new rant giving all the possible details.
I am currently doing my graduation in computer science(in 3rd year). I love to code problems and have an experience of working in various languages like c, c++, java, javascript, html, css, python, swift. When I came into this field, I had a dream of becoming an iOS developer but now seeing all those streams out there(android, machine learning and etc etc), I am really confused. I know that I want to do programming but choosing a career is getting on my nerves and taking the hell outta me. So if anyone of you following devRanters could guide me and help me on this point, I would be highly grateful.
P.S- please don't judge me cause i know i am not good at expressing myself.10 -
Disclaimer - Day in the life of a whitehat student.
Whitehat Whitehat Whitehat
What is this????
When I attended my first white hat jr online free trial class, I got to know that the teachers does not know the difference between java and javascript. Infact they were saying blockly as javascript. I was knowing the difference between the same. There were 3 types of courses -
***Note : - This information is taken from the whitehat official website***
1.) Introduction to Coding :-
Sequence, Fundamentals Coding Blocks, Loops
(Teach us to drag and drop blocks of code.org(blockly))
2.) App Developer Certificate:-
Events / UI,Conditionals, Complex Loop, Logic Structures, Turtle Coding
(Advanced drag and drop(blockly))
3.) Advance Coding with Space Tech -
Extended UI/UX, Rich GUI app, Space Tech simulation in Space Lab / Game Lab, Professional Game Design.
(GUI - with tkinter(python), Game Design - Blockly(code.org))
These things are rubbish ......making GUI's is simplest with tkinter and the students who make games (with code.org) submit their codes to the whitehat community (because the teacher says "they will compile it to an android app, then you can publish it to playstore" --- this is for 1% students who are able to design their own games).
The thing whitehat do with code given by 1% best students:-
Export to HTML from code.org
Download HTML to APK Convertor
Setup SDK
Successfully converted to APK!
Publish it to Whitehat Jr console account
Credits of the students
Income of the exporters
Rest all students will only think to be the CEO of google one day.
My Opinion - StackOverflow, Unity for Game Development, Android Studio, Dart, Flutter and Kivy (using google colab for compiling the python code to an apk) for app development and Flask, HTML, CSS for web development.7 -
Situation: I have a love hate relationship with python due to the lack of types as I have in more established languages such as C#, Java and shit even TypeScript
Situation (cont): A rather large codebase that i have developed for multiple processes at work run on Python.
I don't hate it, I just don't absolutely love it, there is a lot of things to like about Python, but man I do have some conflicts with it, I have been facing out to use other solutions that feel scripty, such as the newer versions of C# with .net, but I would say that about 80% of our codebase runs on Python, the rest is PHP.
I am somewhat traditional in the way my programs run, I started with C++ and Java, then for whatever reason (I blame codecademy at the time) switched over to Ruby and Javascript, mostly Javascript. I do not remember how I found Python, I do remember learning it with an online tutorial, shit was easy to get started with.
My codebase running on Python is huge, and they do a lot from automation scripts, to data gathering and database management, never had I been bitten with the "oh noes is so slow" bug since my code is not Google level big, for everything else Python seems rather fast imho
I dunno, big time love hate relationship9 -
"My code is explain itself. Well, I need no comments to understand it."
I don't care if you wan't to write comments or not; If don't write any then i don't care because fuck you and your code.
May it be java, kotlin, python, javascript or anyother language, you think "everyone can read", i hope you'll never find anyone who has to deal with you and your cancerous code.joke/meme the code explains itself explain code javascript cancerous readability fuck kotlin dealing with other people comments java7 -
I hate how my work mates think coding in Java you automatically become cleaver than most people who code in another laugauge ..
The hate Python and JavaScript , c'mon guys just write your fucking project so long it works you dont have to make statements on how Java is great. . We all no. . Statements like Python is English anyone can write are not welcome7 -
My work product: Or why I learned to get twitchy around Java...
I maintain a Java based test system, that tests a raster image processor. The client is a Java swing project that contains CORBA bindings to the internal API of the raster image processor. It also has custom written UI elements and duplicated functionality that became available in later versions of Java, but because some of the third party tools we use don't work with later versions of Java for some reason, it's not possible to upgrade Java to gain things as simple as recursive directory deletion, yes the version of Java we have to use does not support something as simple as that and custom code had to be written to support it.
Because of the requirement to build the API bindings along with the client the whole application must be built with the raster image processor build chain, which is a heavily customised jam build system. So an ant task calls out to execute a jam task and jam does about 90% of the heavy lifting.
In addition to the Java code there's code for interpreting PostScript files, as these can be used to alter the behaviour of the raster image processor during testing.
As if that weren't enough, there's a beanshell interface to allow users to script the test system, but none of the users know Java well enough to feel confident writing interpreted Java scripts (and that's too close to JavaScript for my comfort). I once tried swapping this out for the Rhino JavaScript interpreter and got all the verbal support in the world but no developer time to design an API that'd work for all the departments.
The server isn't much better though. It's a tomcat based application that was written by someone who had never built a tomcat application before, or any web application for that matter and uses raw SQL strings instead of an orm, it doesn't use MVC in any way, and insane amount of functionality is dumped into the jsp files.
It too interacts with a raster image processor to create difference masks of the output, running PostScript as needed. It spawns off multiple threads and can spend days processing hundreds of gigabytes of image output (depending on the size of the tests).
We're stuck on Tomcat seven because we can't upgrade beyond Java 6, which brings a whole manner of security issues, but that eager little Java updated will break the tool chain if it gets its way.
Between these two components we have the Java RMI server (sometimes) working to help generate image data on the client side before all images are pulled across a UNC network path onto the server that processes test jobs (in PDF format), by reading into the xref table of said PDF, finding the embedded image data (for our server consumed test files are just flate encoded TIFF files wrapped around just enough PDF to make them valid) and uses a tool to create a difference mask of two images.
This tool is very error prone, it can't difference images of different sizes, colour spaces, orientations or pixel depths, but it's the best we have.
The tool is installed in both the client and server if the client can generate images it'll query from the server which ones it needs to and if it can't the server will use the tool itself.
Our shells have custom profiles for linking to a whole manner of third party tools and libraries, including a link to visual studio 2005 (more indirectly related build dependencies), the whole profile has to ensure that absolutely no operating system pollution gets into the shell, most of our apps are installed in our home directories and we have to ensure our paths are correct for every single application we add.
And... Fucking and!
Most of the tools are stored as source bundles in a version control system... Not got or mercurial, not perforce or svn, not even CVS... They use a custom built version control system that is built on top of RCS, it keeps a central database of locked files (using soft and hard locks along with write protecting the files in the file system) to ensure users can't get merge conflicts by preventing other users from writing to the files at all.
Branching is heavy weight and can take the best part of a day to create a new branch and populate the history.
Gathering the tools alone to build the Dev environment to build my project takes the best part of a week.
What should be a joy come hardware refresh year becomes a curse ("Well fuck, now I loose a week spending it setting up the Dev environment on ANOTHER machine").
Needless to say, I enjoy NOT working with Java. A lot of this isn't Javas fault, but there's a lot of things that Java (specifically the Java 6 version we're stuck on) does not make easy.
This is why I prefer to build my web apps in python or node, hell, I'd even take Lua... Just... Compiling web pages into executable Java classes, why? I mean I understand the implementation of how this happens, but why did my predecessor have to choose this? Why?2 -
=Your Human Body!!= what do u think you run on in real life??
What do you think you run on??
Brain: C++
Skin and bones: HTML + CSS
Data: Typescript or Javascript Or Node.js
Walking and breathing: Python
Defense: Java cause every white blood cell is a new class
sleeping is basically C++ packing in all the files unless someone gets drunk they cant pack correctly thats why their brain is probably messed up >=) i would say the beer is corrupted code folders16 -
I have struggled with leet code two years ago when I started university and was learning programming.
Now I am finally set to have a leet code interview at a large company, followed by a take home problem and a system design problem.
I started looking into leet code again today and I feel like I could had done so much more back then if I just had some help.
Back then I made the mistake of doing leet code problems in Java since that's all I knew and it used to make many simple problems last for hours.
I want to try it out using Python this time around since I don't have to focus on every little detail when I solve the problem. The company focuses on Python, Go and JS but I don't know Go and JS well enough.
What do you think? Is it a good idea or not? Should I just try JavaScript?
Also do you have any advice for this kinds of interviews?
i think the leet code one will be the toughest.
Some suggest I should read Cracking the coding interview, but I don't see the point of doing that
Good thing is all interviews are through Zoom since it's coronavirus season.2 -
Im currently a student in the US studying for my CS degree. I am kind of new to programming and after talking to my Professors, they said the best way to get better at coding is by practicing. Anyone have any good ways of practicing? I code in mostly Java, Python, and Javascript. Thank you!10

Cross post from /r/cscareerquestions
Hey guys how are you all doing!?
I got into university this September (Computer Engineering & Informatics).
Although I've been programming java since I was 14 (github.com/zarkopafilis), discussions with a friend who is a dot net guy and has been working full-time C# for 2 years now got me thinking.
Alright, Java's good. I've learned to love and hate the language. I also like Spring Boot and whole this ecosystem of stuff including Scala and the other Java based languages. Currently I'm in the proccess of completing some personal project of mine.
Alright, here's the big question: Assuming I am going to graduate (and start working) in 5-7-8 years (Masters, PhD - who knows), which language would you suggest I stick with and start learning? - for backend programming of course.
Don't tell me JavaScript. Although I don't like it I've digested the fact that I'll have to learn some of it for sure.
Currently that's what I'm thinking: Invest some more time learning how the JVM works (and probably keep improving my code quality). Also learn some more stuff regarding Spring Boot (and/or Web Services in general). Then advance onto Scala till couple of years pass. In that time I shall keep improving my SQL skills.
On the other hand I may start learning C# along with .NETcore .
Sidenote: Personally I prefer statically typed languages, that's why I dislike stuff like js and python although I occasionally find myself fiddling with small projects like some laser tracker written with python + opencv.
Sorry if this reads like a big disorganized dump of thoughts. Thanks in advance! :)3 -
My parents showed me how to play "Spy Hunter" on their Pentium III Windows 98 machine when I was 2, and I started installing games. Fast-forward to elementary school there was a game design afterschool class where we learned to use "Scratch" to drag-n-drop pieces of code used for animating and creating games. I wanted to do "real coding" so I got an internship at a local company, learned HTML, Java, JavaScript, and Python. Now, I'm developing games in Unity engine, and making mods on SourcePawn. The consumer is becoming a creator.

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 -
Worst / best feature of any language:
Lack of / requirement of strict / dynamic / weak / strong typing. Just typing. Typing typing typing just typing.
Having to specify the type in C/++/#, Java/Kotlin is so annoying and delays the project so much by having to do declare weird classes with 3 or 4 fields just because you need it in this tiny line of code.
Not having good type support in JavaScript and Python is a pain in the eyes when you can't find what type each variable is, or when you pass a wrong argument to a function, and when you do, it shows the definition for the type in a .ty or.pyi file and not the definition itself which you have to find elsewhere. Spent half of my uni exams trying to decipher the type while it could've been a piece of cake if you just knew the type.

OK, Started to work on iOS app few months ago. Had to deal with so many xcode and swift problems that it is driving me nuts. How any sane person can code this shit language? I never seen such an idiotic syntax in my life. I worked with so many languages in past 12 years: C++, Java, Python, PHP, Ruby, JavaScript. So many code editors & IDE's: Subline, Notepad++, Eclipse, Jetbrains, VSCode, Atom. But after working XCode and Swift for few months I want to burn down my MacBook that I only had to get to work on this iOS app with this shitty XCode IDE.7
