My boss has never programmed before. Recently, he decided that I should print out all the code for an admittedly rather small project (10k lines of Java code, 200 pages printed out), and then have me explain every line to him.

Luckily, he didn't get past 'public static void main', especially since I hadn't even bothered to print out more than that!

As a Java developer, reasons to kill other programmers:

- static mutable variables
- WRITING to static mutable variables
- API call with Framework X didn't work. Add Framework Y along with X and try that. Wrap X in try/catch statement. Catch block fires framework Y.
- six, seven, ten levels of nested code. Zero thought put in organization
- 6K LOC Java files
- spring (singleton? Maybe) object assigning values in static mutable (see pt.1)
- a couple of unit tests in code base that no longer work. Zero unit tests in new code
- unit testing disabled in CI pipeline
- empty catch blocks
- pass mutable data between threads. Modify in various places concurrently.

My Interview question was simple, just :
Create an algorithm using **JAVA** accepting row input which output corresponding diagram :

I said, well this going to be easy. Turns out they give me one sheet of FUCKING PAPER. ARE YOU OUT OF YOUR MIND? THIS IS JAVA NOT A FUCKING PYTHON.

But in the end i complete the test except i don't write the :

public stupid static motherfucking main(String[] dick){}

in every single number. Got Zero in the test. Didn't get the job.

I win.

Python: I hate the way it uses True/False over true/false

Java: Static. Just fuck static. oh and System.out.println(), why the fuck did they make the basic print function so long to write.

C#: I despise the way the curly braces get automatically put under the function declaration rather than beside it since it's a language style thing.

C: the inability to declare vars in altho declaration of a forloop. Although I think C11 let's you do this.

Javascript: Fucking prototypes.

Coldfusion: it runs like an elephant. Slow and heavy.

Go: The way the compiler won't let you have unused variables/imports. Pain in the ass for testing.

Am I the only one who is triggered by seeing all of the stupid articles claiming Java is bad introduction language? Just becuase Standford decided to change it to JavaScript? What the actual fuck? How students should learn the fundamentals concept of OOP in scripting language?
Don't get me wrong, I hate using Java for real life projects. But there is a reason why almost every university use it as introduciton language. It's great start to learn programming. Saying that the 'Hello World' in Java is complex and can scare people away, it's complete nonsens. For fuck sake, yes programming should be fun, but it is also hard. People can understand that they are going to learn what 'public static voiď means later. It's the structure of many Computer Science classes. It's the assigments that are not designed in engaging and fun way for newcomers. That's the problem, not the language.

I'm currently rewriting perfectly clean and functioning Scala code in Java (because "Enterprise", yay). The amount of unnecessary boilerplate I have to add is insane. I'm not even talking big complicated code but two liners or the lack of simple things like a range from 5 to 10.

Why do I have to write
List<Position> occupiedPositions = placedEntities.stream()
.flatMap((pe) -> pe.occupiedPositions().stream())
.collect(Collectors.toList());
instead of simply
val occupiedPositions = placedEntities.flatMap(_.occupiedPositions)

Why on earth does `occupiedPositions.distinct` suddenly become a monstrosity like `occupiedPositions.stream().distinct().collect(Collectors.toList())` where the majority of code is pure boilerplate? And this is supposed to be the new and better Java8 api which people use as evidence that Java is now suddenly "functional" (yeah no, just no).

Why do APIs that annotate parameters with @Nullable throw NullPointerExceptions when I pass a null? Why does the compiler not help prevent such stupidity? Why do we use static typing PLUS those annotations and it still crashes at runtime like every damn dynamic, interpreted language out there? That's not unfortunate, it's a complete waste of time.

Why is a simple idea like a range from x to 10 (in scala literally `x to 10`) not by default included in Java? There's Guava's version of Range which does not have a helper for integer ranges (even though they are the most used ones). Then there's apache.commons version which _has_ a helper for integers, but is strangely not iterable (wtf I don't even...).

Speaking of Iterable: How difficult could it be to convert an abstract Iterable<T> into a concrete List<T>? In scala it's surprisingly `someIterable.toList`. I found nothing like that so I took to stackoverflow where I found a thread in which people suggested everything from writing your own ListUtils helper class, using Guava (which is a huge dependency!) to using the new Java8 features inline (which is still about three lines long). I didn't know this was such a hard problem in computer science, TIL.

How anyone can be productive in this abomination of a language is beyond me now, even though I've used it for many years while learning to code (back then I didn't know there were much better ways to do things). The only good part is that I have to endure this nonsense for only about 3 days longer then I'm free again!

I've been using microsoft dev stack for as long as i remember. Since I picked up C#/.NET in 2002 I haven't looked back. I got spoiled by things like type safety, generics, LINQ and its functional twist on C#, await/async, and Visual Studio, the best IDE one could ask for.

Over the past few years though, I've seen the rise of many competing open source stacks that get many things right, e.g. command line tooling, package management, CI, CD, containerization, and Linux friendliness. In general many of those frameworks are more Mac friendly than Windows. Microsoft started sobering up to this fact and started open sourcing its frameworks and tools, and generally being more Mac/Linux friendly, but I think that, first, it's a bit too late, and second, it's not mature yet; not even comparable to what you get on VS + Windows.

More recently I switched jobs and I'm mainly using Mac, Python, and some Java. I've also used node in a couple of small projects. My feeling: even though I may be resisting change, I genuinely feel that C# is a better designed language than Java, and I feel that static type languages are far superior to dynamic ones, especially on large projects with large number of developers. I get that dynamic languages gives you a productivity boost, and they make you feel liberated, but most of the time I feel that this productivity is lost when you have to compensate for type safety with more unit tests that would not be necessary in a static type language, also you tend to get subtle bugs that are only manifested at runtime.

So I'm really torn: enjoy world class development platform and language, but sacrifice large ecosystem of open source tools and practices that get the devops culture; or be content with less polished frameworks/languages but much larger community that gets how apps should be built, deployed, monitored, etc.

Damn you Microsoft for coming late to the open source party.

Hi every developer! My name is Allen. English is not my native language so forgive me if I say something that does not make any sense. Let me tell you my story how I become a programmer. (I am still learning) My first computer was a DELL OptiPlex GX 720 desktop. My father bought it for our self-employee job. Before he allow me to use the computer, I used to sit next to him and watching what he do, what he click and what he gets. When he allow me to use the computer, I was slow at typing. One or 2 WPM (word per minute) my father taught me how to use the computer. Very slowly, my typing speed improves. I understand how to use the computer. but one day, I do what make me regret. I was playing with some executables, when I double clicking it, it does not work I used to associate files with apps. I associate music files with every player I want. So, I did what I used to, I associate exe files with windows media center! The computer started to open hundreds of windows media center (WMC for short) whenever an app is clicked, it opens windows media center. Today, I realized that windows were trying to open every app and every process that regularly run. However, since I associate it with WMC, instead of the app itself, it opens WMC some days after the mistake, I wonder how apps work and how I can create my own. My father  told me before that a program is simply a binary file that the computer can read. However, it was too advanced to me at the time.I begin my search with google. Everytime I search, it says "learn to code" or something like that. I see some C++ code but, it was disgusting. when I read just a few lines of a hello world code in java. it was too complex

What I seen

#$$#% $%&$%&*#!@

~

(&*%&$ (_(*^% #&&* (^^$(&^$%^( %^*$())

~

^$70^(`*#%`*#&%^)*!"   Hello world   "#@

~

~

The actual code:

class helloworld

{

    public static void main(String args[])

    {

         System.out.println("Hello World!");

     }

}

I look for an easy way but my attempts fail. then. I push

I to learn how to code.I try learning java. but it still

Very complex. i tried LibertyBASIC. from LibertyBASIC to

Java. after learning LibertyBASIC, it was easy!

LibertyBASIC -> Java -> Ruby -> NOW, C# and XAML

Today, I am learning C# and XAML.

My first OS                         :  Windows 7

My first Computer             :  DELL OptiPlex GX 720

My first successful click  :  The Start menu

My first used App              : Microsoft Encarta 2009

My first created App         : Hi-Lo(number-guessing game. written in LibertyBASIC)

Thankyou for reading this Long story.

 

Yknow, I want to make an android app that I have in my mind for about half a year now and I already tried twice, both with Kotlin and with Java but everytime I try it's just pain and suffering and frustration...

No it's not because of the language, I like Java and I like Kotlin too and I'd say I'm at least decent at Kotlin and really good in Java...

No no.. the issue is the fucking Android SDK and the mix-and-match documentation available online!!!

Every fucking time I want to implement some sort of UI element, user action or a background service and I start googling how to do it It comes with with at least 3 different stack overflow solutions, all of them saying "that way of doing it is deprecated, instead you should X" and looking up the OFFICIAL FUCKING DOCS it will just make me roll up in the corner and cry because of how fucking inconsistent it is and the retarded domain language it uses... fucking transactions for fucking fragments inside fucking activities... because I guess the word "screen"/"view"/"template" or something similar natural just was too mainstream for the all knowing alphabet soup that google is...

And then you start looking up what the fucking difference even is and how to code it up only to find out there's at least 12 other opinions on how fragments should be used and what should be an activity and what should be a damn fragment...

But that's not all, that's just the base... I get a headache even thinking about how the fucking inflating of templates and the entire R. notation works. You want to open a fucking tiny corner menu with the settings options? WELL THEN YOU FUCKING BETTER REMEMBER TO IMPLEMENT IT THROUGH SOME SORT OF EVENT AND INFLATE THE MENU YOURSELF EVEN THOUGH ITS THE SAME FUCKING THING WITH STATIC STRINGS...

AND WHY THE FUCK DO I NEED LIKE 4 NEW FILES TO IMPLEMENT A FUCKING LISTVIEW...
also talking about ListViews... what was wrong with "ListView"... Why do we need a "RecyclerView"... oh right... because the fucks fucked the fuck up and all the legacy components were designed by a monkey and are next to useless! SO WE NEEDED A NEW NAME FOR THE FIXED VERSION, CANT NAME IT LISTVIEW AGAIN... FUCK YOU...

honestly... if I got a dolar for every "what the fuck android" I said during trying to understand that mess I'd be richer by a few hundred...

oh oh oh, but you know what? You don't like the android SDK? that's fine, you can use fucking React or Flutter or something... yeah.. because instead of torturing myself with the android SDK I want to torture myself with an abstraction of the same SDK and JavaScript as the fucking cherry on top... HAVE YOU FUCKING SEEN THE CODE FLUTTER SHOWS ON THEIR WEBSITE AS THE "Introduction" ?!!!

Look at this piece of shit:

[code in attached image, we could really use a proper Markdown support at least for rants]

THAT'S NOT EVEN THE ENTIRE THING, THAT'S JUST THE *REALLY* UGLY PART...

The fucking nesting... What is it with JS and all the fucking nesting everytime?! It looks like shit.... It reads like shit as well...

WHY, in the name OF FUCK, IS THERE MORE THAN 5 ANDROID FRAMEWORKS and ALL of them... used this FUCKING NOVEL idea of programming using A FUCKING BRACKET WALL

It always looks like:
(code(code[code{code(code{code()})}]));

If I wanted to make a fucking app or a website using fucking Haskell I'd do that.... at this point reading assembly code feels like heaven compared to this retardation... Why is this so popular?! WHAT DO YOU PEOPLE SEE IN IT?! Clearly it's not the aesthetics... it looks like a fucking frog vomit running down an emus leg, fuck that.... I don't even hate classic JavaScript, it's a good enough language and it does what I tell it to... but these ugly fucking frameworks like react, angular and whatever else uses this fucking format can go fuck right off. This is not the way JS is gonna get a better name for itself...

So:
Fuck Google

Fuck the marionette that designed the Android SDK

Fuck the Hellspawn the came up with the "functional-like" way of using JavaScript

Fuck everyone that thinks "JavaScript everywhere" is a good thing

And deeply future-fuck everyone that makes a new framework following any of these standards, stucks a .js at the end of the name and releases his hairball.js of an invention into the fucking world....

It's a mess... fuck everything android related...

How I met python
[long read but worth]

There's nothing wrong with falling in love with a programming language for her looks. I mean, let's face it - Python does have a rockin' body of modules, and a damn good set of utilities and interpreters on various platforms. Her whitespace-sensitive syntax is easy on the eyes, and it's a beautiful sight to wake up to in the morning after a long night of debugging. The way she sways those releases on a consistent cycle - she knows how to treat you right, you know?

But let's face it - a lot of other languages see the attention she's getting, and they get jealous. Really jealous. They try and make her feel bad by pointing out the GIL, and they try and convince her that she's not "good enough" for parallel programming or enterprise-level applications. They say that her lack of static typing gives her programmers headaches, and that as an interpreted language, she's not fast enough for performance-critical applications.

She hears what those other, older languages like Java and C++ say, and she thinks she's not stable or mature enough. She hears what those shallow, beauty-obsessed languages like Ruby say, and she thinks she's not pretty enough. But she's trying really hard, you know? She hits the gym every day, trying to come up with new and better ways of JIT'ing and optimizing. She's experimenting with new platforms and compilation techniques all the time. She wants you to love her more, because she cares.

But then you hear about how bad she feels, and how hard she's trying, and you just look into her eyes, sighing. You take Python out for a walk - holding her hand - and tell her that she's the most beautiful language in the world, but that's not the only reason you love her.

You tell her she was raised right - Guido gave her core functionality and a deep philosophy she's never forgotten. You tell her you appreciate her consistent releases and her detailed and descriptive documentation. You tell her that she has a great set of friends who are supportive and understanding - friends like Google, Quora, and Facebook. And finally, with tears in your eyes, you tell her that with her broad community support, ease of development, and well-supported frameworks, you know she's a language you want to be with for a long, long time.

After saying all this, you look around and notice that the two of you are alone. Letting go of Python's hand, you start to get down on one knee. Her eyes get wide as you try and say the words - but she just puts her finger on your lips and whispers, "Yes".

The moon is bright. You know things are going to be okay now.

I've been so pissed off so many times, I thought I should divide them into categories.
- Pissed off at a fellow dev: I told him to use a constant instead of a hardcoded number.
He changed this: obj.method(3);
to this:
public static final int three = 3;
obj.method(three);
- Pissed off at management: I once got a $10 yearly raise.
- Pissed off at a client: They rejected our design proposal because the text was in spanish and they didn't speak spanish. It was lorem ipsum text.
- Pissed off at code: I once had to refactor a 500 line legacy jsp script with HTML, CSS, JS and Java completely intertwined.
- Pissed off at Twitter: They changed their API the day of our go-live, breaking all of their widgets, forcing us to move the go-live date and making me work an additional 8 hours after a week with almost no breaks.
- Pissed off at travel and logistics: They sent me to a hotel in Mexico City 2.5 hours away from the client's office.

Fun times...

- What did a Java static method accused of criminal possession of a weapon said in his deffense?

- "THIS does not belong to me!"

Let's write some Java line by line, go!

public static void main(String[] args) {

Memory just came up from reading another rant about static keyword I wanted to share. Involved a network programming assignment in Java back in my heyday.

Fellow student was told that a static member was shared between every object in a class and decided that they could use that to implement network communication (i.e. if they ran the same java program on different machines, they'd be able to communicate by reading to and writing from the same static fields).

Have a memory of sitting in corner of lab overhearing tutor lose their mind trying to (unsuccessfully) explain why this didn't work.

Biggest annoyance of favorite language:

Python has no static type checking. I know that is not something that is intended for Python. It's just that I enjoy the syntax, but would love the type-safety of something like Kotlin/Java

*Java*
Friend: So I can have variables on interfaces?
Me: Yeah, just that they are final and static
Friend: ...

Learn VIM. Unless you're doing Java or some other compiled static typed language. In that case: learn JavaScript and then learn VIM. 😎

Helped a friend who's currently learning programming in Java
Looked at the slides used to teach them and apparently the teacher explains the "static" keyword as "can be accessed from any function of the class"... Which... Isn't at all what static does
At that point they hadn't started with actual OOP stuff, so I kind of get why they didn't explain what it really does, but why the fuck did they just put down a completely wrong definition?! Instead of just saying "yeah you'll just need that keyword for now, I'll explain it later"

I'm taking a computer sciece course for Java and I'm just getting into it. I have done other similar things but in different languages and one day the class was discussing the meaning of static and all of a sudden he stops projecting his screen and says one moment and I look at what he's doing and he's googling what to do like WTH your supposed to be teaching us not feeding us answers from google

Keeping myself from getting bored af at work. I am a backend engineer doing mostly frontend. And right now it ain't even the interesting stuff. I am merely passing photoshop files to static displays.

Kill me. Every once in a while I do maintenance on Java and PHP apps, but still...bored.....more Rails or Django please

How to write a proper Hello World program in Java:

public class ProperJavaProgram {
    public static void main(String[] args) {
        try {
            // Write the hello world file
            List<String> lines = Arrays.asList(
                    "#include <stdio.h>",
                    "int main() {",
                    "printf(\"Hello World!\\n\");",
                    "return 0;",
                    "}"
            );
            Path file = Paths.get("awesome-program.c");
            Files.write(file, lines, Charset.forName("UTF-8"));

            // Execute the file
            executeCommand("cc awesome-c-program.c -o awesome-executable");
            executeCommand("./awesome-executable");
        } catch (IOException e) {
            System.out.println("You're screwed, just use Java and get over it. " + e);
        }
    }

    public static void executeCommand(String command) {
        try {
            Process p = Runtime.getRuntime().exec(command); // Run the process
            BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream())); // Get the output
            String s; // Print out the output
            while ((s = stdInput.readLine()) != null) {
                System.out.println(s);
            }
        } catch (IOException e) {
            System.out.println("You're screwed, just use Java and get over it. " + e); // UR SCREWED
        }
    }
}

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.

I recently got into an argument with some people, and I want your opinion. I did a speed code in Java (just sped up clip of programming, because it looks cool lol), and someone commented:

"Way too much static abuse here. Jesus"

In which I replied:

"Actually, sir. There is near none at all, just because I use static methods does not make it static abuse. A static method belongs to the class, and is somewhat permanent. It is not a type (instance, cat, dog, animal, etc.) class, it is a Utility class, much like other dependencies you'd use are Utilities and not types."

To which they reply:

"Getting and setting is a Utility?"

Boi. If it is a static variable, yes. Like, what?

When I was young I'd play games and around age 11 received an Xbox for my bday. Hated the case, so I painted the case. Since I had it open looked into getting a replacement fan.Thats when everything changed. I discovered the modding scene and without having any computer background/literacy got to studying.

The program that caught my eye ran on Linux. *shrugs thinking how hard can it be? * Read about Linux and discover dual booting. To do that I needed to resize windows partition. Learn more about partitions and get to it. Finally prepped... Backup in case of the worst, resized windows partition, working Ubuntu bootable USB, and printed install tutorial. Check, check, and check. Install was good. Sort of.

While Ubuntu worked, the broadcam wireless chipset driver did not. Fast forward a week and I feel that i had mastered the terminal basics. And WiFi worked! Go download the aforementioned program and FTP into the Xbox and BOOM... It doesn't work. More days and hours spent researching. In the end it all chalked up to not setting a static IP address on Xbox.

After all was said and done I had a bitchin Xbox. I think the only thing I didn't put on it was some gold spinning rims.

Sad part about that Xbox is that I never used it after. Instead I just kept messing around with Linux and learning more about computers. Taught myself HTML/CSS. Learned more about shell scripting. Then Windows cmd basics. Tried programming languages but felt a little overwhelmed. Only messed with <10 lines of code to tweak existing programs.

Now I'm learning C# and loving it. Planning on C++ or Java next!

Sooooo ok ok. Started my graduate program in August and thus far I have been having to handle it with working as a manager, missing 2 staff member positions at work, as well as dealing with other personal items in my life. It has been exhausting beyond belief and I would not really recommend it for people working full time always on call jobs with a family, like at a..

But one thing that keeps my hopes up is the amount of great knowledge that the professors pass to us through their lectures. Sometimes I would get upset at how highly theoretical the items are, I was expecting to see tons of code in one of the major languages used in A.I(my graduate program has a focus in AI, that is my concentration) and was really disappointed at not seeing more code really. But getting the high level overview of the concepts has been really helpful in forcing me to do extra research in order to reconnect with some of the items that I had never thought of before.

If you follow, for example, different articles or online tutorials representing doing something simple like generating a simple neural network, it sometimes escapes our mind how some of the internal concepts of the activity in question are generated, how and why and the mathematical notions that led researchers reach the conclusions they did. As developers, we are sometimes used to just not caring about how sometimes a thing would work, just as long as it works "we will get back to this later" is a common thing in most tutorials, such as when I started with Java "don't worry about what public static main means, just write it up for now, oh and don't worry about what System.out.println() is, just know that its used to output something into bla bla bla" <---- shit like that is too common and it does not escape ML tutorials.

Its hard man, to focus on understanding the inner details of such a massive field all the time, but truly worth it. And if you do find yourself considering the need for higher education or not, well its more of a personal choice really. There are some very talented people that learn a lot on their own, but having the proper guidance of a body of highly trained industry professionals is always nice, my professors take the time to deal with the students on such a personal level that concepts get acquired faster, everyone in class is an engineer with years of experience, thus having people talk to us at that level is much appreciated and accelerates the process of being educated.

Basically what I am trying to say is that being exposed to different methodologies and theoretical concepts helps a lot for building intuition, specially when you literally have no other option but to git gud. And school is what you make of it, but certainly never a waste.

When I first began with Python I really missed the static typed checking from Java, I barely know anything about a returned object from a method and have to read the API extensively for every new library.

After a while I finally understand why Python is so powerful, the combination of dynamic typed language and rich default methods make the language unbeatable for your productivity.

While Java's Object only has toString(), hashCode(), equals() or clone(), Python's basic Class has every fucking method for every scenario I could ever image. No wonder that libraries like numpy or pandas work so well and fluidly.

Today I learned:

In Java, you're supposed to compile a source file in its package one directory up, outside of its package. You can't compile the source file in its own package directory, for it will state "cannot find symbol" on files in the same package, even though they're in the correct package directory. That can be quite confusing at first.

Given the following directory structure:

|_
|_ \pkg
|_ _ Src1.java
|_ _ Src2.java (interface with static method)

and the following source:

package pkg;
public interface Src2 { static void doStuff() { ... }; } // assuming JDK8+, where static default methods are allowed

package pkg;
public class Src1 { public static void main(String[] args) { Src2.doStuff(); } }

..being inside the pkg/ directory in the console,

this won't work:
javac -cp . Src1.java

"cannot find symbol: Src2"

However, go one directory up and..

javac -cp pkg/*.java pkg/Src1.java

..it works!

Yeah, you truly start learning how the compiler works when you don't use the luxury of a IDE but rather a raw text editor and a console.

Can't touch this

C# has static binding by default. Meaning methods aren't overrideable unless you specifically tag them as virtual. I love how in java you can take someone else's random class and override everything with some additional or alternate behaviour.

participating at an coding challenge.

the mission is to write an game solver for an game engine - in java. based on astar, pathfinding should be made possible by cloning objects.
never seen a so hardly misconcepted challenge, where character instances and their variables are static and contain uncloneable data😂 oh god what a waste of time realizing this bs

We had to add licensing to a program of us. In the end we chose a small java-library for that and i wrote a convenience script that creates a valid license.
But the script got its input from static strings and that was its doom.

My boss cloned the repo with the script (and jars), replaced the strings with real world data and pushed.
For his conveinience, because there were several clients, he copied the data-section, commented out the first one and put another data into the second section. This happened a few times and HE PUSHED AGAIN.

Now this repository contains a fine record of everyones licenses and their passwords. I know it shouldn't bother me, but it still gets my eye twitching, just like md5-hashing on passwords (which actually happens on that licensed project)

I kept wondering why would anyone declare a private static variable until I needed one myself.

U've seen one dev creating Java-Classes like 'GetLevel' which contain only one method that is called 'getLevel'. And it wasn't even a static method.

Any other people here that find Python to be actually a harder language than Java? With Java it's much easier to keep track of your code and to track what variables refer to certain object types.

It feels like Python has much more quirks and feels therefore much more inconsistent as a language. Object oriented programming is more verbose with static methods and decorators being vague for example. This makes it harder to grasp concepts like design patterns and SOLID principles in Python imo.

So i wasted last 24 hours trying to satisfy my ego over a shitty interview and revisiting my old job's codebase and realising that i still don't like that shit. just i am 25 and have no clue where am i heading at. i am just restless, my most of the decisions in 2023 have given very bad outcomes and i am just trying doing things to feel hopeful.

context for the interview story-----
my previous job was at a b2b marketing company whose sdk was used by various startups to send notifications to their users, track analytics etc. i understood most of it and don't find it to be any major engineering marvel, but that interviewer was very interested in asking me to design a system around it.

in my 1.2 years of job there, i found the codebase to be extremely and unnecessarily verbose ( java 7) with questionable fallbacks and resistance towards change from the managers. they were always like "we can't change it otherwise a lot of our client won't use our sdk". i still wrote a lot of testcases and tried to understand the working of major features.

BTW, before you guys go on a declare me an embarrassment of an engineer who doesn't know the product's code base, let me tell you that we are talking SDKs (plural) and a service based company here. their was just one SDK with interesting, heavy lifting stuff and 9 more SDKs which were mostly wrappers and less advanced libraries. i got tasks in all of them, and 70% of my time went into maintaining those and debugging client side bugs instead of exploring the "already-stable-dont-change" code base.

so based on my vague understanding and my even more vague memory from 1 year ago, i tried to explain an overall architecture to that interviewer guy. His face was screaming the word "pathetic" from his expressions, so i thought that today i will try to decode the codebase in 12-15 hours, publish a cool article and be proud of how much i know a so called martech system design. their codebase is open sourced, so it wasn't difficult to check it out once more.
but boy oh boy i got so bored. unnecessary clases , unnecessary callbacks static calls , oof. i tried to refactor a few classes, but even after removing 70% of codebase, i was still left with 100+ classes , most of them being 3000-4000 files long. and this is your plain old java library adding just 800kb to your project.

boring , boring stuff. i would probably need 2-3 more days to get an understanding of complete project, although by then i would be again questioning my life choices , that was this a good use of my 36 hours?

what IS a correct usage of my time? i am currently super dissatisfied with my job, so want to switch. i have been here for 6 months, so probably i wouldn't be going unless i get insane money or an irresistible company offer. For this i had devised a 2 part plan to either become good at modern hot buzz stuff in my domain( the one being currently popularized by dev influenzas) or become good at dsa/leetcode/cp. i suck bad at ds/algo stuff, nor am i much motivated. so went with that hot buzz stuff.

but then this interview expected me to be a mature dev with system design knowledge... agh fuck. its festive season going on and am unable to buy any cool shirts since i am so much limited with my money from my mediocre salary and loans. and mom wants to buy a home too... yeah kill me

Best:
- I built a good automation mechanism with a decent UI [slackbot]
- used as few frameworks and ext libs as I could. Mostly based on bare java
- client wanted to migrate it to Spring
- got 3 peeps assigned for the migration
- 2 months later their effort failed.
- win: my project has not been molested with Spring

Worst:
- i had an idea to develop smth on top of jmeter, using jmeter as a lib
- I downloaded and imported jmeter's src code
- static contexts, singletons, jmx/rmi everywhere [java is deprecating rmi support]
- not gonna happen... Not gonna build a new project on top of a legacy codebase.

My visceral hate of Spring.Net burns with the force of a thousand suns.

Almost everything it does is done wrong or solved better by other solutions.

Specifying which classes to instantiate from .xml files? Sure why not, compile type safety (the whole reason for using a static programming language) is obviously overrated and dependency based injection is surely impossible!
And for extra bonus points, now our client code must be aware of the internals of the service classes, and all of their references as well, because, encapsulation? Who cares.

Have you made an typo? Good fucking luck finding out from which of the 100 config files we have floating around...

And, because it has baked in AOP and Transactions its woven into the fabric of the project like a tapewom.

Of course this may just be how our "special snowflake" project uses Spring.

What makes it more painful is that I love good DI tools (ninject, castlewindsor, autofac, there are so many...) and we're stuck with this turd because 7 years ago some java devs couldn't be arsed to learn a new library...

I once had to implement a program to process CSV files. One line would be one order, so I wrote a class with a static factory method (Java) instead of an ordinary constructor, because I needed to throw exceptions if something with the line was wrong (which now and then was the case: invalid product IDs, missing fields and the like). After I committed my changes (CVS was still common in those days), a coworker (let's call him Max) asked me what the hell I was doing there. He expected me to replace the code (perfectly working, by the way) with either an ordinary constructor or by implementing "the factory pattern properly". His rationale: "We don't have those kinds of things in our code base!" So I let him argue a bit, not finding any well substantiated reason for me to "fix" the code. So Max wanted to team up with another developer in our office (let's call him Rick), explained the "issue" to him. I just sat there and enjoyed, knowing that Rick would not really care. But as soon as Rick understood what I did, he walked over to the book shelf, picked "Effective Java" from it, opened the book at chapter 1 and said to Max: "Look, Josh Bloch suggests doing it exactly that way for the problem at hand!" Max kept on arguing for a while, because his "rationale" (see above) was not affected by the fact that the code was actually good. It just didn't appear in our code base before.

Why does java have so many nonsensical limitations? Why? Why can't we have multiple heritage? Why can't we have friend classes? Why can't we make static abstract methods? Oracle, PLEASE.

So, I need to customize some shit for my company's app...

Just discovered they somehow manage to call a protected method on an object stored in a field... I can't even... How does that even compile? And also, things neccessary for my subclass are private with no getter...

private static final int ZERO = 0;
private static final int ONE = 1;
private static final int TWO = 2;

What. The. Hell. Why?

Damn Java. Though this is the programmer's fault, it does seem to favor this kind of shit.

"Learning" kotlin for android dev has been a wild ride yet. Kotlin is kinda cool, a mix between python and Java but with many nice features. Then again there are kotlin features on which I just scratch my head like data classes and companion objects.
And then for android (not kotlin specific) I see things like calling Timepicker(...) or Timepicker Dialog(...) without assigning it to a variable and wonder how that can even work. Can someone explain? There's no creation method, static method or anything?
I feel like a competent and incompetent dev at the same time.

Java apparently thinks it would be too convenient if we would use comparison operators on enumerations.

If you have to use the .ordinal() every time you want to do such a thing, you make the code uglier that you're trying to clean up to begin with!

Time to do this the hard way:
public static final int YELLING = 0;
public static final int SCREAMING = 1;

I've been trying Flutter the past 2days. I liked how amazing Flutter framework is but I also hated how UGLY the Dart language is. First of all, I've been doing Java(Android) and JSX(React). So, after coming from these languages, Dart seems awful. Here are the things that I hated the most:
1. JSON parsing: The worst part of Flutter/Dart. No GSON/Jackson equivalent. not even possible to make one as described in the doc
2. Redux for flutter. I tried and I hated it. So, Tried some other state management libs
3. the way static functions are written in a class
4. Widgets hiarachy
5. Ambiguity - "this context is not the context we need, we need that one to make it work. so, pass that even when you don't have it" (if you have used flutter, you will know what I mean)

Never underestimate the power of a misplaced static in your Java to totally fuck you over.

I was busy with my computer science project for the semester where we have to implement a Sudoku solver without backtracking by using graph theory.

So there I was writing my data structure for the grid when for some reason all the cells were initialized with the value 8.

After a whole night of debugging I was about to start over when I realized I had made my array static.

And boom, it works. WTF!!!!!!!

How do you remember difference between const, static and final?

!rant "Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference."

I'm learning Java/Android Development with the Udacity Nanodegree (hey we all gotta start somewhere). Got to one project that was intended just to demonstrate use of basic form elements in a static quiz. Predicted time was about 20m I think.

Three days, much hair pulling, and many SO pages later I've built a little app that displays any number and type of question, dynamically generating the views.

I may do things the hard way, but I learn a heck of a lot more for doing so.

Java I hate you! I've been stuck on an authentication issue for weeks now and just figured out what was wrong. The probem was my variable wasn't STATIC so it was passing in an old auth header every time. Literally I've been skimming and modifying my code like crazy for like 2 weeks and this simple modifier changes everything! Java I hate you and can't wait to migrate my code base to kotlin!

so i had this day at college we were supposed have a viva ( oral test ) ..the teacher asked me to print hello world..in java but no where can i use a static method including 'main'..well i made a static block instead and added System.exit in it.. and i had to write the complete syntax of main else it wont run..but my teacher snapped back at me saying it could be done.. with a non static main

..nodded an okay..didnt want a fight..came home..figured out the thing she said is now obsolete.. fuckin hell..update yourself at least..

Writing unit tests and need to deal with static methods, which are using dependency injection.

Static typing in Java

How to write programs on Android 10 that work with files/directories? Have used a number of JVM-based languages like Groovy, Clojure and Kotlin.

My last try was with Groovy. I ran it under Dcoder which has to be cloud-, based as it supports numerous languages. I gave it permission to access storage but got a file not found error from Java. Copied this excerpt for the file path.

import java.io.File

class Example {

static void main(String[] args) {

new File("/storage/emulated/0/read_file.grvy").eachLine {

line -> println "line : $line";

}

}

}
Do I need root? Do I need to change file permissions using Termux? Why can't I find a way to write simple software on a Motorola Super, 3 GB RAM and 8 cores? I hate using a phone for a computer but a seizure has me in a nursing home with only one usable hand.

Any help is greatly appreciated.

I wrote about Java sockets and networking a few weeks ago. As a follow up, how would you manage state in a scenario with a server and multiple clients? A few solutions I've thought of:

Making the client and the server share a common class that makes the both of them know what can and can not be done.

Having a "Message" class which will contain a static method for parsing a received payload and return a Message instance with intent and methods to resolve intent (i.e. sending data to the client).

Perhaps both concepts should be used, or perhaps none. I'd like to hear your ideas :)

Oh yeah ... Java is cool in an utterly sick way even that i can't seem to find a non-retarded built-in stack data structure
Call me a racist, but java.util.Stack has a removeIf() method in case you want to remove odd numbers:

import java.util.Stack;

public class App {
public static void main(String[] args) {
int arr[] = { 2, 4, 7, 11, 13, 16, 19 };
Stack<Integer> s = new Stack<Integer>();
for (int i = 0; i < arr.length; i++) {
s.push(arr[i]);
}
s.removeIf((n) -> (n % 2 == 1));
System.out.println(s); // [2, 4, 16]
}
}

Stop using java.util.Stack they said, a legacy class they said, instead i should use java.util.ArrayDeque, but frankly i can still keep up being racist (in a reversed manner):

import java.util.ArrayDeque;
import java.util.Deque;

public class App {
public static void main(String[] args) {
int arr[] = { 2, 4, 7, 11, 13, 16, 19 };
Deque<Integer> s = new ArrayDeque<Integer>();
for (int i = 0; i < arr.length; i++) {
s.push(arr[i]);
}
s.removeIf((n) -> (n % 2 == 1));
System.out.println(s); // [16, 4, 2]
}
}

The fact that you can iterate through java.util.Stack is amazing, but the ability to insert element in a specified index:

import java.util.Stack;

public class App {
public static void main(String[] args) {
int arr[] = { 2, 4, 7, 11, 13, 16, 19 };
Stack<Integer> s = new Stack<Integer>();
for (int i = 0; i < arr.length; i++) {
s.push(arr[i]);
}
s.add(2, 218);
System.out.println(s); // [2, 4, 218, 7, 11, 13, 16, 19]
}
}

That's what happens when you inherit java.util.Vector, which is only done a BRAIN OVEN person, a very brain oven even that it will revert to retarded

If you thought about using this type of bullshit in Java get yourself prepared to beat the disk for hours when you accidentally call java.util.Stack<T>.add(int index, T element) instead of java.util.Stack<T>.push(T element), you will probably end up breaking the disk or your hand, but not solving the issue

WHY THE F*** CAN'T WE HAVE A WORKING NORMAL STACK ?

Anyone know about attacks on static variable in JVM? Any links?

overclocked gd learned java lmao he said it was too easy for him

about my java experince:
(i still suck at creating classes and static methods which i need to learn more on especially inheritance for my java game)

Now for some kotlin and python time

just note that i completed all exersizes but im still at java classes category but how bad could the android api be?

Here are few questions that you could expect when attending a Java interview

1 - In which programming paradigm Java 8 falls?
2 - What is MetaSpace? How does it differ from PermGen?
3 - What are functional or SAM interfaces?
4 - What are static methods in Interfaces?
5 - What are the various categories of pre-defined function interfaces?
