LONG RANT AHEAD!

In my workplace (dev company) I am the only dev using Linux on my workstation. I joined project XX, a senior dev onboarded me. Downloaded the code, built the source, launched the app,.. BAM - an exception in catalina.out. ORM framework failed to map something.

mvn clean && mvn install

same thing happens again. I address this incident to sr dev and response is "well.... it works on my machine and has worked for all other devs. It must be your environment issue. Prolly linux is to blame?" So I spend another hour trying to dig up the bug. Narrowed it down to a single datamodel with ORM mapping annotation looking somewhat off. Fixed it.

mvn clean && mvn install

the app now works perfectly. Apparently this bug has been in the codebase for years and Windows used to mask it somehow w/o throwing an exception. God knows what undefined behaviour was happening in the background...

Months fly by and I'm invited to join another project. Sounds really cool! I get accesses, checkout the code, build it (after crossing the hell of VPNs on Linux). Run component 1/4 -- all goocy. run component 2,3/4 -- looks perfect. Run component 4/4 -- BAM: LinkageError. Turns out there is something wrong with OSGi dependencies as ClassLoader attempts to load the same class twice, from 2 different sources. Coworkers with Windows and MACs have never seen this kind of exception and lead dev replies with "I think you should use a normal environment for work rather than playing with your Linux". Wtf... It's java. Every env is "normal env" for JVM! I do some digging. One day passes by.. second one.. third.. the weekend.. The next Friday comes and I still haven't succeeded to launch component #4. Eventually I give up (since I cannot charge a client for a week I spent trying to set up my env) and walk away from that project. Ever since this LinkageError was always in my mind, for some reason I could not let it go. It was driving me CRAZY! So half a year passes by and one of the project devs gets a new MB pro. 2 days later I get a PM: "umm.. were you the one who used to get LinkageError while starting component #4 up?". You guys have NO IDEA how happy his message made me. I mean... I was frickin HIGH: all smiling, singing, even dancing behind my desk!! Apparently the guy had the same problem I did. Except he was familiar with the project quite well. It took 3 more days for him to figure out what was wrong and fix it. And it indeed was an error in the project -- not my "abnormal Linux env"! And again for some hell knows what reason Windows was masking a mistake in the codebase and not popping an error where it must have popped. Linux on the other hand found the error and crashed the app immediatelly so the product would not be shipped with God knows what bugs...

I do not mean to bring up a flame war or smth, but It's obvious I've kind of saved 2 projects from "undefined magical behaviour" by just using Linux. I guess what I really wanted to say is that no matter how good dev you are, whether you are a sr, lead or chief dev, if your coworker (let it be another sr or a jr dev) says he gets an error and YOU cannot figure out what the heck is wrong, you should not blame the dev or an environment w/o knowing it for a fact. If something is not working - figure out the WHATs and WHYs first. Analyze, compare data to other envs,... Not only you will help a new guy to join your team but also you'll learn something new. And in some cases something crucial, e.g. a serious messup in the codebase.

Every day.

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...

Intelligence had a future till...

Timezones. So, general rules are:

1. If you don't store timezone, always use and assume UTC. Databases, backends, whatever you use, all time must be kept be in UTC.
2. If you store timezones, ensure you store them everywhere and don't drop them anywhere.
3. It's always better to ignore backend server time in favor of database's `now().` Having a single source of truth makes time consistent (if it's the same database, obviously). If you combine backend time and database time, you likely get a violation of causality.

I've just spent a couple of hours investigating "weird random one-hour time drifts on updates." Guys violated all three rules above:
- they didn't store the timezone;
- their servers had inconsistent timezones. Java was in +XX., while the server itself in UTC. On one host, they forgot to put JVM in the same timezone;
- they dropped the timezone because they thought it was the same everywhere, so there was no point in serializing it.

(I wrote most of this as a comment in reply about Microsoft buying GitHub on another rant but decided to move it here because it is rant worthy. Also, no, I'm not a Microsoft employee nor do I have any Microsoft stock).

Microsoft buying GitHub makes sense. They contribute more to the open source community on GitHub than any other company. (Side note, they also contribute/have contributed to the Linux Kernel).

Steve Ballmer isn't running the show anymore. Because of that, we have awesome things like:

* Visual Studio Code - Completely free and powerful light weight IDE for coding in just about any script or language. This IDE is also open source, hosted on GitHub. It can be installed on Win/Mac/Linux.

* Visual Studio Community Edition: fully featured flagship IDE free for solo developers and students, can be installed on Win/Mac.

* Fully featured Sql Server running in a Docker container.

* .Net Core, which can be compiled to native binaries of Windows, MacOS AND Linux. You can't even do that with Java, you have to first have the JVM installed in order to run any kind of Java code on any of those operating systems. .Net Core is also an absolutely beautiful framework with so many features at your disposal.

...and more.

Yes, they've done bonehead things in the past but who/which company hasn't. Yes, they have Cortana. Yes, they force Bing on you when searching with Cortana (does anyone actually regularly use Cortana? Or Bing?). Yes, their operating system costs money. Yes, their malware-style Upgrade-to-Windows-10 tactics were evil and they admitted such. Yes, they brought ads and other unfortunate things to Skype. I'd be lying if I said I wasn't concerned about that Skype bit translating over into GitHub. BUT, the fact that so many of their employees use GitHub daily means they are dogfooding the platform, which is a positive thing.

Despite the flaws, from the perspective of a software engineer they really should be given a lot of credit for all these new directions they are moving in now. They directly aim to help and contribute to the developer community. Plus, Windows 10 is finally getting a dark theme! haha.

I think Microsoft buying GitHub makes a lot of sense. Of course do what you want about it, feel how you want about it, but casting the same ol' shade at them for anything they do seems a bit like automatic reflex more than anything else.

I'm bracing myself for the impending wave of angry hornets from the nest I just kicked. In all seriousness though, I welcome discussion on the topic even if you feel differently than I do. I'm not saying there's no reason to dislike them, just saying there are lots of new reasons to hate them less and/or appreciate what they are doing now.

Yes I know java. Java is a beast. document.getElementById() always saves my life 😕

HoD in my college is a "22 year experienced C programmer" with a PhD in CS.

One day I went to him and told, it is very hard to work with TurboC, and it isn't needed as we can easily migrate to GCC.

He asked me why was I complaining. No other student has any problem. They have been using it ever since the college started and everyone was "comfortable" with it.

I stood silent. He then went on to say, even JVM was coded in TurboC. I nodded and left the office as i didn't have an argument.

He's the same guy who had earlier said, "printf returns an array of characters printed", so I guess everything works here.

The best thing about Java is that you can cook French fries on your CPU while running the JVM

I code, drink, and from Java (yes it's an actual place). Except my life doesn't run on JVM. Or does it?

If I have a bug in my Java program, please don't tell me "Use Python. It has a library for that, you can do it in 2 lines".

Motherfucker, I'm not asking for a solution in Python, nor am I asking you to pick my language for me. The rest of the project is in JVM languages, and I'm not gonna rewrite the whole damn thing so i can use your precious little script-kiddie language

If I show you Java code, I don't want Python. I never want Python. FOR THE LOVE OF ALL THAT IS FLUFFY, STOP TRYING TO FORCE-FEED ME PYTHON

I bypassed SSL certificate verification because that goddam certificate had some flags which my JVM did not understand and threw errors. Still in prod after 10+ years 🤐

Many thanks MySQL. Really a good way to implement a driver. Go fuck yourself.

Our team makes a software in Java and because of technical reasons we require 1GB of memory for the JVM (with the Xmx switch).
If you don't have enough free memory the app without any sign just exits because the JVM just couldn't bite big enough from the memory.
Many days later and you just stand there without a clue as to why the launcher does nothing.
Then you remember this constraint and start to close every memory heavy app you can think of. (I'm looking at you Chrome) No matter how important those spreadsheets or illustrator files. Congratulation you just freed up 4GB of memory, things should work now! WRONG!
But why you might ask. You see we are using 32-bit version of java because someone in upper management decided that it should run on any machine (even if we only test it on win 7 and high sierra) and 32 is smaller than 64 so it must be downwards compatible! we should use it! Yes, in 2019 we use 32-bit java because some lunatic might want to run our software on a Windows XP 32-bit OS. But why is this so much of a problem?
Well.. the 32-bit version of Java requires CONTIGUOUS FREE SPACE IN MEMORY TO EVEN START... AND WE ARE REQUESTING ONE GIGABYTE!!
So you can shove your swap and closed applications up your ass but I bet you that you won't get 1GB contiguous memory that way!
Now there will be a meeting about this issue and another related to the issues with 32-bit JVM tomorrow. The only problem is that this issue only occures if you used up most of your memory and then try to open our software. So upper management will probably deem this issue minor and won't allow us to upgrade to 64-bit... in 20fucking19

Wow. Such comment. Much useful.

Tbh anything related to the JVM is burnout within a few minutes by now. I absolutely despise it and would even rather write in the original C

sooooooooo for my current graduate class we were to use the MVC pattern to build an IOS application(they preferred it if we did an IOS application) or if you didn't have an Apple computer: an Android application.

The thing is, they specified to use Java, while in their lectures and demos they made a lot of points for other technologies, hybrid technologies, such as React Cordova, all that shit, they even mentioned React Native and more. But not one single mention of Kotlin. Last time I tried my hand at Android development was way before Kotlin, it was actually my first major development job: Mobile development, for which we used Obj C on the IOS part and well, Java on the Android part.

As some of you might now, I rarely have something bad to say about a tech stack(except for VBA which I despise, but I digress) and I love and use Java at work. But the Android API has always seem unnecessarily complex for my taste, because of that, when I was working as a mobile development I dreaded every single minute in which I had to code for Android, Google had a great way to make people despise Java through their Android API. I am not saying it is shit, I am not saying it is bad, I just-dont-like-it.

Kotlin, proves a superior choice in my humble opinion for Android development, and because the language is for retards, it was fairly easy for me to pick it up in about 2 hours. I was already redesigning some of my largest Spring applications using half the code and implemented about 80% of the application's functionality in less than 3 hours(login, fragment manipulation, permissions, bla bla) and by that time I started to wonder if the app built on Kotlin would be ok. And why not? If they specifically mentioned and demonstrated examples using Swift, then surely Kotlin would be fine no? Between Kotlin and Java it is easy to see that kotlin is more similar to Swift than Java. So I sent an email. Their response: "I am sorry, but we would much rather you stick with the official implementations for Android, which in this case is Java for the development of the application"

I was like 0.o wat? So I replied back sending links and documentation where Google touted Kotlin as the new and preferred way to develop Android applications, not as a second class citizen of the platform, but as THE preferred stack. Same response.

Eventually one of the instructors reflected long enough on it to say that it was fine if I developed the application in Kotlin, but they advised me that since they already had grading criteria for the Java program I had to redo it in Java. It did not took me long really, once I was finished with the Kotlin application I basically rewrote only a couple of things into Java.

The end result? I think that for Android I still greatly prefer Kotlin. Even though I am not the biggest fan of Kotlin for anything else, or as my preferred language in the JVM.

I just.......wish....they would have said something along the lines of: "Nah fam please rewrite that shit for Java since we don't have grading criterias in place for Kotlin, sorry bruh, 10/10 gg tho" instead of them getting into an email battle with me concerning Kotlin being or not being the language to use in Android. It made me feel that they effectively had no clue what they were talking about and as such not really capable of taking care of students on a graduate level program.

Made me feel dirty.

Friend: why do I get this error help

[I check the logs]

Me: uh,its a OOM, did you allocate enough memory for GC?

Friend: wait hold on

[changes a method]

[works]

Friend: I shouldn't use this experimental method

Me: Cool man blog it

Running code in a JVM ... which is a virtual machine...
Inside a VM that runs Linux...
Inside a host OS that runs on native...which runs on a CISC processor... that internally runs a RISC architecture... so that makes the CISC a VM...
The RISC architecture I am pretty sure runs on Elf Magic... I am fairly certain Turing was an Elf working for Santa...
So I am really running my code on VM Elf Magic

Got back into android development recently and while everything was pretty flawless ( I managed to get the basic concepts implemented in a day) something wasn't right.

For some reason I was not happy with the code i wrote, although I took examples from google and tried to adapt their code style. It looked aweful. I hated my code.
But the code itself wasn't the core of the problem. I could easily add new features and replace components with new implementations without breaking the app. All those "good code quality" identifiers were there.

Turn out the problem is Java. Or to be more specific: Java 1.6
Every listener which only calls a single function once a worker has finished needs 6 lines of code. If you implement the inferface in the class it gets messy once there are multiple workers and you have a generic interface. And there are no lambdas!

So I made the switch to Kotlin.
The app was converted to kotlin in 30 Minutes​. Android studio can convert the classes automatically and very little manual work is needed afterwards.
After that I spent 2 hours replacing the old java concepts with Kotlin concepts: lamdas, non-nullable types, getters and setters in kotlin style (which in this case is c# style) and some other great thing.
The code is good looking now. I like it. I like kotlin as it has a lot of cool things.
Its super easy to learn. It took me about 2 hours to get into it. It combines concepts from java, javascript, c# and maybe a few other languages to form a modern jvm 1.6 compatible typesafe language.

Android dev is fun again!

So, today I tried using my C/++ Code in Java using native jvm stuff.
It's cancer to make it work but damn it's cool.

Running a fucking conda environment on windows (an update environment from the previous one that I normally use) gets to be a fucking pain in the fucking ass for no fucking reason.

First: Generate a new conda environment, for FUCKING SHITS AND GIGGLES, DO NOT SPECIFY THE PYTHON VERSION, just to see compatibility, this was an experiment, expected to fail.

Install tensorflow on said environment: It does not fucking work, not detecting cuda, the only requirement? To have the cuda dependencies installed, modified, and inside of the system path, check done, it works on 4 other fucking environments, so why not this one.

Still doesn't work, google around and found some thread on github (the errors) that has a way to fix it, do it that way, fucking magic, shit is fixed.

Very well, tensorflow is installed and detecting cuda, no biggie. HAD TO SWITCH TO PYHTHON 3,8 BECAUSE 3.9 WAS GIVING ISSUES FOR SOME UNKNOWN FUCKING REASON

Ok no problem, done.

Install jupyter lab, for which the first in all other 4 environments it works. Guess what a fuckload of errors upon executing the import of tensorflow. They go on a loop that does not fucking end.

The error: imPoRT eRrOr thE Dll waS noT loAdeD

Ok, fucking which one? who fucking knows.

I FUCKING HATE that the main language for this fucking bullshit is python. I guess the benefits of the repl, I do, but the python repl is fucking HORSESHIT compared to the one you get on: Lisp, Ruby and fucking even NODE in which error messages are still more fucking intelligent than those of fucking bullshit ass Python.

Personally? I am betting on Julia devising a smarter environment, it is a better language already, on a second note: If you are worried about A.I taking your job, don't, it requires a team of fucktards working around common basic system administration tasks to get this bullshit running in the first place.

My dream? Julia or Scala (fuck you) for a primary language in machine learning and AI, in which entire environments, with aaaaaaaaaall of the required dlls and dependencies can be downloaded and installed upon can just fucking run. A single directory structure in which shit just fucking works (reason why I like live environments like Smalltalk, but fuck you on that too) and just run your projects from there, without setting a bunch of bullshit from environment variables, cuda dlls installation phases and what not. Something that JUST FUCKING WORKS.

I.....fucking.....HATE the level of system administration required to run fucking anything nowadays, the reason why we had to create shit like devops jobs, for the sad fuckers that have to figure out environment configurations on a box just to run software.

Fuck me man development turned to shit, this is why go mod, node npm, php composer strict folder structure pipelines were created. Bitch all you want about npm, but if I can create a node_modules setting with all of the required dlls to run a project, even if this bitch weights 2.5GB for a project structure you bet your fucking ass that I would.

"YOU JUST DON'T KNOW WHAT YOU ARE DOING" YES I FUCKING DO and I will get this bullshit fixed, I will get it running just like I did the other 4 environments that I fucking use, for different versions of cuda and python and the dependency circle jerk BULLSHIT that I have to manage. But this "follow the guide and it will work, except when it does not and you are looking into obscure github errors" bullshit just takes away from valuable project time when you have a small dedicated group of developers and no sys admin or devops mastermind to resort to.

I have successfully deployed:
Java
Golang
Clojure
Python
Node
PHP
VB/C# .NET
C++
Rails
Django

Projects, and every single fucking time (save for .net, that shit just fucking works on a dedicated windows IIS server) the shit will not work with x..nT reasons. It fucking obliterates me how fucking annoying this bullshit is. And the reason why the ENTIRE FUCKING FIELD of computer science and software engineering is so fucking flawed.

But we can't all just run to simple windows bs in which we have documentation for everything. We have to spend countless hours on fucking Linux figuring shit out (fuck you also, I have been using Linux since I was 18, I am 30 now) for which graphical drivers for machine learning, cuda and whatTheFuckNot require all sorts of sys admin gymnasts to be used.

Y'all fucked up a long time ago. Smalltalk provided an all in one, easily rollable back to previous images, easily administered interfaces for this fileFuckery bullshit, and even though the JVM and the .NET environments did their best to hold shit down, and even though we had npm packages pulling the universe inside, or gomod compiling shit into one place NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO we had to do whatever the fuck we wanted to feel l337 and wanted.

Fuck all of you, fuck this field, fuck setting boxes for ML/AI and fuck every single OS in existence

When someone talks shit on Java

I hate that I have to be careful of what I say about specific languages so that I don't hurt peoples feelings. If you get upset because someone called Java or PHP ugly, get over it.

All languages are shit. If you have a favorite, good for you. IMO you only limit yourself if you think that .Net is always the answer, or if you think that every project needs to be in a JVM.

We often forget to ask why a language exists before we start to use it. No sane person is going to use Java to develop a quick one time script. Same can be said for all languages.

So when someone tells you, "Python sucks" they probably mean, "Python sucks for this use case". Except for Perl.

Fuck Perl.

Var X1 = "" ;
Var X2 = "" ;
Var A = "" ;
Var A2 = 1;

...why. Just why ever name variables like that.

Let's create mentally what should never be, something with so ridiculously bad performance, even the devil wouldn't let someone use it.

My idea: a JVM emulator written in JavaScript.

What can you come up with?

Create this fucking account just to say: FUCK XAMARIN!

Mono is great on Linux, but Xamarin.Android is a GAY RETARD!

Fucking Xamarin.Android apps are retarded, wait for them 3 fucking seconds and a simple Hello World app doesn't start.

Retarded Xamarin.Forms make the whole pile of shit a lot worse using fucking abstractions and stuff. And the geniuses at Uno Platform does not make this shit any better.

Why don't those nerds at Xamarin make a way to compile all C# code to native JVM bytecode and provide all C# core libraries AS NATIVE JAVA LIBRARIES, RATHER THAN LOADING A NEW USELESS RETARDED VIRTUAL MACHINE ON THE JVM?

So that's it. Guess there's no way to write good Android apps using C#.

I am making an LDAP user manager and porting application for my workplace.

The thing is, i made the first version of it in PHP already. Shit works fine and it without an issue.

But

I had an itch to redesign it using another tech stack that would be speedier, more tested and using a more established platform.

Enter Clojure, a Lisp dialect for the JVM. In a single day I managed to get 80% of the application done. We have about 80k users inside of our ldap system(maybe more) and I tested it with 150 accounts, so far so good.

If this works I will be the first person to deploy a Clojure application, not only for my organization, but for the city as a whole while simultaneously being able to say that I got a Lisp app deployed and working :D

I am loving this. Really wanna have a Lisp app out there and add it to my resume.

The head of my department, an old timer and really ancient dev smiled heavily when I showed him the codebase. Not only is it minimal, it is concise and elegant :D

I love Clojure

And Texas

There are a couple of them to list! But to sum my main ones(biggest personal heroes):

John McCarthy, one of the founding fathers of Artificial Intelligence and accredited with coining such term(sometimes before 1960 if memory serves right), a mathematical prodigy, the man based the original model of the Lisp programming language in lambda calculus. Many modern concepts that we have in programming where implemented in one way or another from his systems back in the day, and as a data analyst and ML nut.....well I am a big fan.

Herb Sutter: C++ programmer extraordinaire. I appreciate him more for his lectures and published articles than anything else. Incredibly smart and down to earth and manages to make C++ less intimidating while still approaching it with respect.

Rich Hickey: The mastermind behind Clojure, the Lisp dialect for the JVM. Rich is really talented and his lectures behind his motivations and reasons behind everything he does with Clojure are fascinating to see.

Ryan Dahl: Awww shit y'all know how it is. The man changed web development both in the backend and the frontend for good. The concept of people writing their own servers to run their pages was not new, but the Node JS runtime environment made it more widely available to people by means of a simple to use language that was already popular with web developers. I would venture to say that Ryan's amazing contributions to JS made the language better, as it stands, the language continues to evolve and new features that make it overall better keep being added. He is currently building Deno, which would be a runtime environment for TypeScript, in Rust.

Anders Hejlsberg: This dude was everywhere man....the original author of Turbo Pascal and the lead of Delphi back in the day. These RAD tools paved the way for what would be a revolution in the computing world. The dude is also the lead architect and designer of the C# programming language as well as TypeScript.
This fucker is everywhere and I love it.

Yukihiro "Matz" Matsumoto: Matsumoto san is the creator of the Ruby programming language. Not only am I a die hard fan of Ruby, but of the core philosophies that the man keeps as the core of his language design: Make the developer happy, principle of least surprise. Also I follow: minswan which is a term made by the Ruby community that states Mats is nice so we are nice. <---- because being cool to others is better than being a passive aggressive cunt.

Steve Wozniak: I feel as if the man does not get enough recognition...the man designed the Apple || computer which (regardless of how much most of y'all bitch and whine) paved the way for modern micro computers. Dude is also accredited with designing one of the first programmable universal remotes(which momma said was shitty) but he did none the less.

Alan Kay: Developed Smalltalk and the original OOP way of doing things. Smalltalk as a concept is really fucking interesting. If you guys ever get the chance, play with Pharo, which is a modern Smalltalk. The thing is really interesting and the overall idea of Smalltalk can be grasped in very little time. It sucks because the software scales beautifully in terms of project building, the idea of hoisting a program as its own runtime environment and ide by preserving state through images is just mind blowing to me. Makes file based programs feel....well....quaint.

Those are some of the biggest dudes for me. I know that the list is large, but I wanted to give credit to the people that inspired me the most. Honorary mention goes to other language creators and engineers of course, but it would be way too large to list!

Me yesterday evening:

"Fuck java, fuck JVM, fuck everything about it, shit doesn't work for some reason, no runtime errors, no compiler errors, no syntax errors, nothing, *turns off computer*".

Me today morning(coffee = false), after comparing the documented example code provided by the API with one someone else made, I've noticed that the one provided by the API was messed up and couldn't work.

"Lemme change that one value in the properties...okay here we go"
Shit works out perfectly.

FUCK FALSELY DOCUMENTED CODE

FUCK DOCUMENTATIONS IN GENERAL

Learning Rust.

Holy brainfucking brain melt, those references, scoping and borrowing and cloning and whatnot, because there is no garbage collector, but also no direct memory management.

It's cool, but also hard for a noob coming from the JVM/Android. The compiler error messages are helpful, but I immediately found some cryptic ones that don't help me at all.

If I had a gun to my head and I had to choose between C#and Java (not like a JVM language like Scala), I think I would go with C# nowadays.
Thoughts while playing around with .Net Core on Linux Mint 17.

When JVM does weird shit on the server

"Kotlin, why the fuck would you want to introduce a better language for Android studio and still base it entirely on jvm, fuck you jetBrains and Google, you java dick sucking retards. "
LOL

It is the JVM

I used to be a Java fanboy.

After seeing the modern things one can do with other languages I am just disappointed, that Java is so old-fashioned.
Some would say "BUT IT HAS LAMBDAS".
Good, that we have lambdas. We don't have optional parameters or objects (like in JS's {} or PHP's stdClass).
JVM may have many advantages, but I think, that Java is slowly dying although it is kept alive by some companies, still using Java in prod.
I think, that Kotlin is, what Java should have been.

I hope, that my wishes will be implemented in Java 10. If not, Java is considered as dead.

Python haters, gather 'round

oh come on... In java it's all simple as 123. You build an app, you have like 200 dependencies, you pack it all in a single fat jar and only deploy that single .jar. Don't need no internet, no installs, no pip, no nothing: just your .jar file and the JVM.

So java:
- build an app
- use 200+ deps
- build your whole project into a single fat jar
- deploy your jar in the env
- install [*khem khem* scp into the server] jre
- run

Now let's look at py, shall we?
- build an app
- use 1 dep
- deploy all the 20 .py files in the env
- make sure you have internet access
- install python
- install pip
- pip install <my dependency>
- run your app

How the Common Lisp Community will eventually die soon:

Clojure is the only main Lisp dialect having some sort of heavy presence in today's modern development world. Yes, I am aware of other(if not all) environments in which Lisp or a dialect of it is being used for multiple things, CADLisp, Guile Scheme, Racket, etc etc whatever. I know.

Not only is Clojure present in the JVM(I give 0 fucks about whether you like it or not also) but also has compilation targets for Javascript via Clojurescript. This means that i can effectively target backend server operations, damn near everything inside of the JVM and also the browser.
Yet, there is no real point in using Lisp or Clojure other than for pure academic endeavours, for which it is not even a pure functional programming language, you would be better served learning something else if you want true functional purity. But also because examples for one of the major areas in software development, mainly web, are really lacking, like, lacking bad, as in, so bad most examples are few in between and there is no interest in making it target complete beginners or anything of the like.

But my biggest fucking gripe with Lisp as a whole, specifically Common Lisp, is how monstrously outdated the documentation you can find available for it is.

Say for example, aesthetics, these play a large role, a developer(web mostly) used to the attention to detail placed by the Rails community, the Laravel community, django, etc etc would find on documentation that came straight from the 90s. There is no passion for design, no attention to detail, it makes it look hacky and abandoned. Everything in Lisp looks so severely abandoned for which the most abundant pool of resources are not even made present on a fully general purpose language constrained as a scripting environment for a text editor: Emacs with Emacs Lisp which I reckon is about the most used Lisp dialect in the planet, even more so than Clojure or Common Lisp.

I just want the language to be made popular again y'know? To have a killer app or framework for it much like there is Rails for Ruby, Phoenix for Elixir, etc etc. But unless I get some serious hacking done to bring about the level of maturity of those frameworks(which I won't nor I believe I can) then it will always remain a niche language with funny syntax.

To be honest I am phasing away my use of Clojure in place of Pharo. I just hate seeing how much the Lisp community does in an effort to keep shit as obscure and far away from the reach of new developers as possible. I also DESPISE reading other Lisp developer's code. Far too fucking dense and clever for anyone other than the original developer to read and add to. The idea that Lisp allows for read only code is far too real man.

Lisp has been DED for a while, and the zombies that remain will soon disappear because the community was too busy playing circle jerks for anything real to be done with it. Even as the original language of AI it has been severely outshined by the likes of Python, R and Scala, shit, even Javascript has more presence in AI than Lisp does now a days.

Im learning kotlin but heres what i dont get..

is it a completely new language that uses jvm concept like java or is it a template over java with extra stuff like C++ and C.

when i import a library in kotlin that exists in the java sdk does it use that or all the libraries are made for kotlin.

is kotlin java++ basically or is it something completely different

sorry if its a dumb question still nee at this

How do you determine how much memory to allocate for your applications?

Sufficient memory * 2?

We're both senior devs, I use nodeJS/Python. Stop forcing your Java *superiority* shit on me. I can write the API using either language. Also fuck your JVM. FUCK THAT SHIT

One of the things that I like the most regarding Clojure(and most Lisps to be honest) is how "not for beginners" the ecosystem feels.
Don't get me wrong, setting up a project in lein with dependencies(both internal and external) is a cakewalk, installing lein or boot is a cakewalk. Setting environment consts and middleware etc etc is a cakewalk.
Its just that there are no blogs about convoluted and amateurish ways of doing things. Most presentations and articles are written by really experienced and talented individuals.

I dunno, its just a nice shift in community. Its nice to see people not fucking up Object Oriented programming in java or any of the other oop languages. Its nice not seeing people giving horrible advice regarding memory management in C or c++ and it is sure as shit nice to not see spaghetti php und js code.

And my productivity levels are off the charts man. Really liking this shit and I get to stay inside my JVM

James Gosling. Not for java itself, but for the idea of the jvm.

Question to the Java developers here:

Is it always the case that Oracles documentation and actual implementation don't match?

Man I have no idea how my company is running as stable as they do. Every time I peak under the curtain of some piece of machinery I find such bad practices…

Just found out our in house database manager only supports listing all objects in a table, updating objects by first reading each row you need to update and only support “select *” queries.

This is after having to argue with some engineers that using http or grpc when interacting with the new service I’m writing in the none-jvm language is better than writing our own driver for their custom rpc and service discovery system.

But like honestly I’d be mad if these decisions had a visible performance impact on the business, but it somehow doesn’t… this is bizzaro world where all I learned from my 8 years experience as a professional goes out the window…

Know what is funny about the Lisp family of languages?
The most powerful is Common Lisp, the most useful by current standards is Clojure(since it can target the JVM as well as JS and I think the .net runtime)

Yet the most widely used by a laaaaaarge margin: Emacs Lisp

I just think that is funny.

Setting up a single node Hadoop cluster. Then installing intellij idea, to find that it doesn't detect any installed jdk. Then uninstalled all jdks, and then reinstalled one, then Hadoop won't work. Now everything seems fine.

Starting up the new Java project I'm assigned to.
Just to see that this project is made of pure black magic and tears of forsaken devs.
Crashing the jvm with segfaults on a regular basis is just one part of the magic.

Now I understand why no one volunteered for this project...

I'm leaving my team and looking for someone replacing me. The HR gave the number of a candidate for a call:
- me calling: hi, we are looking for a backend dev with at least one year experience on a jvm langage.
- the guy: oh, I was doing some java, but I don't know jvm langage.
- me: :/

Why Java?

So where's the clojure squad at?

Me and the dba are slowly migrating parts of our JVM stack into .NET AND even tho I love and will always love Java and its ecosystem....I am glad.

IIS as a server is something that I actually look forward to since deploying shit to it is always a breeze

Installing ssl certs is a breeze

Everything is a fucking breeze

Before any of you cocksuckers say anything: this is my opinion only

Analogy: Assume a JVM is a kingdom, Object is a king of the kingdom, and GC is an attacker of the kingdom who tries to kill the king(object).
When King is Strong, GC can not kill him.
When King is Soft, GC attacks him but King rule the kingdom with protection until resource are available.
When King is Weak, GC attacks him but rule the kingdom without protection.
When king is Phantom, GC already killed him but king is available via his soul.

So Phantom ref is basically GC saying "Omaewa mo shindheru" and the object saying "Nani???"

My teacher keeps saying GVM instead of JVM, that really pisses me off 😠

I am so sick of this place. Production deployment shouldn't be such a massive cluster fuck of different departments and sometimes redundant configurations. Knowing who to talk to about a problem shouldn't change daily, and it shouldn't be hard to figure out.

My jvm doesn't appear to be running in production. I hunt down the fucker who is supposed to be handling this problem today...but he's out of office and no one knows who his stand in is...GODDAMNIT!

kawa - a modern JVM language

I feel like front end guys and gals are basically the folks that make the back end guys and gals look good for the boss. Not in a straight dev shop, but when your boss thinks html is a programming language...

You knoe, my first insights into computer programming came out of spite. I thought windows to be garbage and wanted to blame someone other than myself for my machine constantly crashing. Thus I discovered programming and down the rabbit hole. But my interest in computer science came from videogames. Portal in particular. I found the idea of GlaDOS fascinating and thought that artificial intelligence would be something interesting to research. The web then gave me Lisp, and boy was the language different from all the other languages I went through. I remember feeling super excited when Racket, Common Lisp and eventually Clojure would help me discover many different ideas. Every time I work with reduce or maps or stuff like that in other languages I always thank languages such as Clojure for having me descipher different ways of manipulating data to get a result. To this day I feel sad whenever I find that my languages do not have the same constructs that Clojure has. I mention Clojure because it is my favorite flavor of Lisp. But one thing that always remains grest to me is firing up Emacs and plugin my code to Slime or Cider and see the repl pop up waiting for something to happen. This feeling is beautiful.

Please guys, if you have not tried it, do so! You might hate it at first or push it aside. But trust me, once you get it it will really change the way you think about programming in general. Try the great Clojure for the Brave and true, and go through the third chapter succesfully. If you do not like Lisp by them then no harm done! You would at least know that there are other options.

Now, here are some cool things:
For the standard implementation, try Common Lisp

For a more modern Scheme, try Racket or Guile

For targetting the JVM try Clojure (more akin to Common Lisp) or Kawa (scheme like)

For the python AST get Hy (pun totally intended)

For JS try Clojurescript

For emacs scripting try Emacs Lisp (has way too many disasdvantages but still relatively close to common lisp)

Honorific mention to more pure functional programming languages for Haskell, F#, Ocaml.

Also worth mentioning that Js , Ruby and Python have great functional constructs.

Life must be running on a JVM, because everything seems to be in the dumps today. 🗑👀

The year was 2006. During the first half of my career, I use to work in the NOC. This was before I made my transition to software engineer. I worked on the third shift for a bank services company. The company was on a down turn. Just years earlier they just went public, and secured a deal with a huge well known bank. Eventually they entered a really bad contract with the bank and was put into a deal they couldn't deliver on. The partnership collapse and their stock plummeted. The CEO was dismissed, and a new CEO came in who wanted to "clean things up".

Anyway I entered the company about a year after this whole thing went down. The NOC was a good stepping stone for my career. They let me work as many hours as I liked. And I took advantage of it, clocking in 80 hours a week on average. They gave me the nick name "Iron Man".

Things started to turn around for the company when we were able to secure a support contract with a huge bank in the Alabama area. As the NOC we were told to handle the migration and facilitate the onboarding.

The onboarding was a mess with terrible instructions that didn't work. A bunch of software packages that crashed. And the network engineers were tips off, as they tunnel between our network and the banks was too narrow, creating an unstable connection between us and them. Oh, and there were all sorts of database corruption issues.

There was also another bank that was using an old version of our software. The sells team had been trying to get them off our old software for over a year. They refuse to move. This bank was the last one using this version, and our organization wanted to completely cut support.

One of the issue we would have is that they had an overnight batch job that had an ETA to be done by 7 AM. The job would often get stuck because this version of the software didn't know how to fail when it was caught in an undesired state. So the job hung, and since the job didn't have logging, no one could tell if it failed unless the logs stopped moving for an hour. It was a heavily manually process that was annoying to deal with. So we would kill the JVM to "speed" the job up. One day I killed the JVM but the job was still late. They told me that they appreciated the effort, but that my job was only to report the problem and not fix it.

This got me caught up in a major scandal. Basically they wanted the job to always have issues everyday. Since this was critical for them, all we needed to do was keep reporting it, and then eventually this would cause the client to have to upgrade to our new software. It was our sales team trying to play dirty. It immediately made me a menace in the company.

For the next 6 months I was constantly harassed and bullied by management. My work was nitpicked. They asked me to come into work nearly everyday, and there was a point I worked 7 days with no off days. They were trying to run me so dry that I would quit. But I never did.

On my last day at the company, I was on a critical call with a customer, and my supervisor was also on the line. My supervisor made a request that made no sense, and was impossible. I told her it wasn't possible. She then scalded me on the call in front of customers. She said "I'm your supervisor, you're just a NOC technician, you do what I say and don't talk back". It was embarrassing to be reprimanded on a call with customers. I never quite recovered from that. I could fill myself steaming with anger. It was one of the first times in my adult life that I felt I really wanted to be violent towards someone. It was such a negative feeling I quit that day at the end of my shift with no job lined up.

I walked away from the job feeling very uncertain about my future, but VERY relieved. I paid the price, basically unable to find a job until a year and a half later. And even was forced to move back in with my mother. After I left, the company still gave my a severance. Probably because of the supervisor's unprofessional conduct in front of customers, and the company probably needed to save face. The 2008 crash kept me out of work until 2009. It did give me time to work on myself, and I swore to never let a job stress me out to that degree. That job was also my last NOC job and the last job where did shift work. My next few jobs was Application Support and I eventually moved into development full time, which is what I always wanted to do.

Anyway sorry if it's a bit long, but that's my burnout story.

Today, my manager received a brand new Macbook pro with all its cool features while I am still stuck using an old Macbook pro (mid 2012 model). I always complained him about performance issues and all he did was to approve an OS upgrade (to Sierra). How does that even enable me to be productive? I am already running applications at the peak of the machine limits. Sometimes, the JVM crashes and other time Node.js runs out of heap space.

The manager is not a programmer. All he really does is attend online meetings, track and report to management, and write emails. Ideally, he would need a Mac Air or perhaps a Windows machine. I still wonder how did the company management allowed this. He is simply misusing his privileges as a manager and I can do nothing about it.

What the fucking fuck. Arquillian you piece of shit.
I have a service that needs to go to production soon, it contains Arquillian tests. The tests work locally but not when going through our new Jenkins pipeline. The error message simply says: "Could not start Arquillian container".
Well fuck you too.
After 3 fucking days of rewriting configs, changing up things and I dont know what else I did, I stubled upon the most hidden error message in the history of error messages, a small little line that says "Could not find or load main class ".
Those 2 spaces are intentional btw, because the fucking error was that when starting arquillian and reading the config there was A FUCKING SPACE too much in my JVM arguments. This piece of shit iterpreted it as my FUCKING MAIN CLASS. Whhhhyyyyy, whhhyyyy. Who the fuck... AAAAAAAAAHHH

Btw I snuck myself on devrant a few weeks back and managed to get my 100++ today. Really love this place 😊

I often wonder why JS is the only language that has the native support from browsers and native built in DOM apis?
The world has come up to a saturation point for so many techs:
- if a software is needed to be created for mobile, it must go through 1 layer of java (aka JVM) or objective C (i guess? for ios) before being understood by the CPU

- if a software is needed to be run via browser( which itself is made to run on jvm, objective c or machine language), it must go through one layer of js interpretters before being understood by the CPU

all the OS are made on C but the application and application platforms are made on specific languages. I wonder why can't there be a single application platform, if all of them(browser, JVM,objective C and whatever .exe apps run on) are doing the same thing and are equally mature to handle every usecase?

Serverless and death of Programming?!

_TL;DR_
I hate serverless at work, love it at home, what's your advice?
- Is this the way things be from now on, suck it up.
- This will mature soon and Code will be king again.
- Look for legacy code work on big Java monolith or something.
- Do front-end which is not yet ruined.
- Start my own stuff.

_Long Rant_

Once one mechanic told me "I become mechanic to escape electrical engineering, but with modern cars...". I'm having similar feelings about programming now.

_Serverless Won_
All of the sudden everyone is doing Serverless, so I looked into it too, accidentally joined the company that does enterprise scale Serverless mostly.
First of all, I like serverless (AWS Lambda in specific) and what it enables - it makes 100% sense and 100% business sense for 80% of time.

So all is great? Not so much... I love it as independent developer, as it enables me to quickly launch products I would have been hesitant due to effort required before. However I hate it in my work - to be continued bellow...

_I'm fake engineer_
I love programming! I love writing code. I'm not really an engineer in the sense that I don't like hustle with tools and spending days fixing obscure environment issues, I rather strive for clean environment where there's nothing between me and code. Of course world is not perfect and I had to tolerate some amounts of hustle like Java and it's application servers, JVM issues, tools, environments... JS tools (although pain is not even close to Java), then it was Docker-ization abuse everywhere, but along the way it was more or less programming at the center. Code was the king, devOps and business skills become very important to developers but still second to code. Distinction here is not that I can't or don't do engineering, its that it requires effort, while coding is just natural thing that I can do with zero motivation.

_Programming is Dead?!_
Why I hate Serverless at work? Because it's a mess - I had a glimpse of this mess with microservices, but this is way worse...

On business/social level:
- First of all developers will be operations now and it's uphill battle to push for separation on business level and also infrastructure specifics are harder to isolate. I liked previous dev-devops collaboration before - everyone doing the thing that are better at.
- Devs now have to be good at code, devOps and business in many organisations.
- Shift of power balance - Code is no longer the king among developers and I'm seeing it now. Code quality drops, junior devs have too hard of the time to learn proper coding practices while AWS/Terraform/... is the main productivity factors. E.g. same code guru on code reviews in old days - respectable performer and source of Truth, now - rambling looser who couldn't get his lambda configured properly.

On not enjoying work:
- Lets start with fact - Code, Terraform, AWS, Business mess - you have to deal with all of it and with close to equal % amount of time now, I want to code mostly, at least 50% of time.
- Everything is in the air ("cloud computing" after all) - gone are the days of starting application and seeing results. Everything holds on assumptions that will only be tested in actual environment. Zero feedback loop - I assume I get this request/SQS message/..., I assume I have configured all the things correctly in sea of Terraform configs and modules from other repos - SQS queues, environment variables... I assume I taken in consideration tens of different terraform configurations of other lambdas/things that might be affected...

It's a such a pleasure now, after the work to open my code editor and work on my personal React.js app...

WTFFFFFFFFOMFG

Why is setting Java path so frustrating? My $JAVA_HOME is supposedly be in my /usr/lib/jvm/java-8-oracle directory but Nautilus shows up nothing!

It's like I'm head first inside the rabbit hole. Fuck

‪-What movie would Java, Scala & Kotlin watch together?‬
‪-The Fault in Our JVM‬

The JVM ecosystem has the best debugging experience ever created

Change my mind

Intellij Idea for JVM Languages.

VSCode for JS.

I started to learn Kotlin today and am already confused:
Is there any difference between between Ant, Maven and Gradle?

I wanted to learn a new language.
Started looking through jvm languages first because thats where i feel home, but they are all just subpar versions of java.
Then i started looking at script languages but anything they do, i can just do with java (i know js too, dont recommend that)
Out of the other languages, c# is the only thing that can give me something extra through unity, but hell, i can just use jMonkey.

So my questions is, can you give me languages that are both useful and unique? Also, opinions on Rust please.

Why the fuck is gradle so horrible.

I literally have no idea why anyone would ever use this thing (other than being forced too because somehow the rest of the world is using it).

Every plugin has an arbitrary DSL that you have to magically know by piecing together enough snippets. At that point, no one is actually intuiting anything based on the beauty of the DSL, every build is a frankenstein of different snippets that were pasted from different versions of gradle blog posts or SO posts.

And if you do get it o work then the DSL changes, or it isn't compatible with another plugin.

I just want to write a fucking integration test in Kotlin. Can I just add an `integrationTest` task in `tasks` right next to `tasks.test`? No, obviously it goes in the `kotlin jvm() compilations` section, DUH.

The first thing anyone in the universe should have asked is "how is this better than literally hand writing a makefile"? At least then I would be able to see the commands that it ran.

Now I'm googling how to make the new jvm-test-suite plugin work when you're using the Kotlin plugin but every single result on Google for `jvm-test-suite kotlin` just returns the docs for jvm-test-suite (whose snippets obviously didn't work in my project) because those doc pages have "Kotlin" written above each of the gradle snippets.

Please just end this.

Oh and dev rant sucks too. It thinks anything separated by dots in a url.

Random thoughts on more out of the box tools/environments.

Subject: Pharo

Some time ago I had shown one of my coworkers about Pharo and he quickly got the main idea behind it but mentioned how he didn't like the idea of leaving behind his text editor to deal with source code.

Some time last week I showed the dude some cool 3d animations you can do with Pharo while simultaneously manipulating the code to change them in real time. Now that caught his attention particularly and he decided he wanted to know more about the language but in particular the benefits of fucking around with an image based environment rather than a file based.

Both of us reached the conclusion that image based makes file based dev enviroments seem quaint in comparison, but estimated that it was nothing more than a sentiment rather than a fact.

We then considered what could be the advantage/disadvantages of such environments but I couldn't come up with anything other than the system not having something like Vim or VS Code or whatever which people love, but that it makes up for it with some of the craziest IDE tools I had ever seen. Plugins in this case act like source code repos that you can download and activate into your workflow in what feels something similar to VS Code being extended via plugins written in JS, and since the GUI is maleable as it is(because everything is basically just subsets of morp h windows) then extending functionality becomes so intuitive that its funny

Whereas with Emacs(for example) you have to really grind your gears with Elisp or Vimscript in Vim etc etc, with Pharo your plugin system is basicall you just adding classes that will convert your OS looking IDE into something else.

Because of how light the vm machine is, portability is a non issue, and passing pharo programs arround is not like installing Java in which you need the JVM.

Source code versioning, very important, already integrated into every live environment and can be extended to do pushes through simple key bindings with no hassle.

I dunno, I just feel that the tool is too good to be true. I keep trying to push limits into it but thus far I have found: data visualization and image modeling to work fine, web development with Teapot to be a cakewalk and work fine, therr are even packages for Arduino development.

I think its biggest con would be the image based system, but would really need to look into how this is bad by any reason other than "aww man I want vim!" since apparently some psychos already made Emacs and VS code packages for interfacing with Pharo source trees.

Embedded is certainly out of the question for any real project since its garbage collected and not the most performant cookie in the jar.

For Data science I can see some future, seems just as intuitive and interesting as a Jupyter Notebook actually, but the process can't and will not be the same since I still don't know of a way to save playground snippets unless you literally create classes for it, in which case every model you build gets saved inside of an object, sounds possible but, strange since it is not a the most common workflow in jupyter.

Some of the environment is sometimes glitchy, but it does have continuos development and have not found many hassles.

There is a biased factor from my side: I seem to be wired to understand the syntax and simple object model better than in other languages. To me this feels natural as if I was just writing ideas rather than code, mostly because I feel that there really ain't much in terms of syntax, the language gets out of my way and the IDE feels like the most intuitive environment in the world to me. I can see why some people would find it REALLY weird of counterintuitive tho.

Guess I really am a simple dude.

Holy shit, what a language...
I'm currently learning Java right, I have never seen such a weird language in my life.
My background is Web Developing and some lua here and there. After a while playing around with Kivy and other alternatives to native Android Studio development I decided it was most probably time for me to start actually getting ready for the inevitable Android Studio.
Getting used to the GUI was easy, everything seemed to make sense and I was already used to IntelliJ.
But the issue came from Java, the number of ways that it's broken, just JVM by itself should be enough to condemn this language to eternal doom. Not even talking about the Syntax, coming from JS it was basically Hell.
I get it's more than useful, but seeing its History, Java should've probably stayed at its Oak stage lmao.

Recently joined a team that does Scala development. It's so refreshing I just love the language

I'm starting to wonder whether or not the JVM was really intended as a foundation for time machines.

I hate the fucking Spring WebFlux and the goddamn Project Reactor on which it depends!
Even debugging a simple CRUD microservice with simple business logic is such a pain in the ass, exception handling has a lot of "magic" implicit stuff which makes me waste hours in fucking trial & error and I have to use very little breakpoints because if a request is paused for more than few seconds it gets terminated.
I love functional programming but why shove it in fucking Java making me waste 90% of my time in trying to guessing what the fucking framework is doing, why not just use Scala which runs in the JVM? We don't even need compatibility with legacy code since it's a greenfield project!

And before you ask yes, I read a fucking book about Project Reactor and Java reactive programming and a lot of docs on Spring, Spring Boot and Spring Web Flux.

despite not running on the jvm, i quite like go

Scala vs Kotlin, which one would you choose, and why?

I am in jvm hell. I have been given a task to add mockito tests. All the existing documentation concerning junit 4 is out of date. Need to use junit 5. All mockito tutorials are out of date. I thought mockito was stupid before junit 5. Now it is “really” stupid. The tutorials I am reading are shit. We have wandered into bleeding edge fucktardness. Kill me now.

A beginner in learning java. I was beating around the bushes on internet from past a decade . As per my understanding upto now. Let us suppose a bottle of water. Here the bottle may be considered as CLASS and water in it be objects(atoms), obejcts may be of same kind and other may differ in some properties. Other way of understanding would be human being is CLASS and MALE Female be objects of Class Human Being. Here again in this Scenario objects may differ in properties such as gender, age, body parts. Zoo might be a class and animals(object), elephants(objects), tigers(objects) and others too, Above human contents too can be added for properties such as in in Zoo class male, female, body parts, age, eating habits, crawlers, four legged, two legged, flying, water animals, mammals, herbivores, Carnivores.. Whatever.. This is upto my understanding. If any corrections always welcome. Will be happy if my answer modified, comment below.

And for basic level.

Learn from input, output devices

Then memory wise cache(quick access), RAM(runtime access temporary memory), Hard disk (permanent memory) all will be in CPU machine. Suppose to express above memory clearly as per my knowledge now am writing this answer with mobile net on. If a suddenly switch off my phone during this time and switch on.Cache runs for instant access of navigation,network etc.RAM-temporary My quora answer will be lost as it was storing in RAM before switch off . But my quora app, my gallery and others will be on permanent internal storage(in PC hard disks generally) won't be affected. This all happens in CPU right. Okay now one question, who manages all these commands, input, outputs. That's Software may be Windows, Mac ios, Android for mobiles. These are all the managers for computer componential setup for different OS's.

Java is high level language, where as computers understand only binary or low level language or binary code such as 0’s and 1’s. It understand only 00101,1110000101,0010,1100(let these be ABCD in binary). For numbers code in 0 and 1’s, small case will be in 0 and 1s and other symbols too. These will be coverted in byte code by JVM java virtual machine. The program we write will be given to JVM it acts as interpreter. But not in C'.

Let us C…

Do comment. Thank you

When someone decides the customer should be allowed execute Jython scripts in the same JVM as your project executes that is already using all the memory due to other poor design choices

Stitching old frameworks / libraries together...

What a lovely joy.

An override here... Testing if it runs.

Oh lovely, shitty shaded jars.

Creating other project for shitty shaded jar.

An override here, an override there...

Oh we need some system property to unfuck JVM upgrade...

Since it's shaded, need to add overrides for the non shaded and shaded variant...

Done...

Back to framework / library....

Another override, another system property...

Its seemingly endless.

Stitching together old shit with new shit to get JDK 20 plus running.

I hate everything.

How I feel about people in a meeting

Listening to someone others participating in some meeting (on speaker) (I'm not a part of):
checking configurations, talking about config hierarchies, addressing network stack limitations, etc -- all smart-sounding things. They must be very wise and experienced. It's got to be something very serious they're working on

Participating in a meeting myself:
wtf is he talking about, does he even know what JVM is? No no, this configuration does not make ANY sense. No, Mr manager, this is not how it works. Come on guys, you all running like a headless chicken - USE COMMON SENSE!!

I wonder if anyone else noticed that... I've been noticing this since the very beginning of my IT career.

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! :)

C- let's See
C is a procedurally developed language follows sequential method of solving a problem.
Example
If a teacher of an Institute teaching various subjects, Maths, English, Science and History.
Case1.One student comes and asks teacher to teach English
and next student to teach Maths,
And the other to teach History.
Case2.Next students comes for English
Case3.Other one for History.

So what I understood regarding C is procedural language is
It completes first case1,next case2, and then case3. (Task after task)
Here English is taught 2 times seperate
And History too 2 times separately making time and process complexity.

C is a platform based high level language support only desired platform. If I program in windows with i3 processor , it runs only on the same OS and Processor, if code is run in other computers.
Single threaded, if a code is interrupted in between, stops there and doesn't allow other part of the code to run.

Java
In this if the same above cases encountered then and tell
Computer to create a Class of English and tell all the students to attend the class(time saving, No complexity and not repetitive)
Same way Creating History class and make all students attend the class at once.
Students may be the objects created.
Multi threaded language, if a task is interrupted following code cannot be stopped. Allows other part of thecode to run.

JVM- Java virtual machine allows Java code into signs that can be understood by computer. Where as C converts into binary code.

A class concept added to C language become C++

tfw a company jvm takes 10 minutes to start because it is bloated with shared libraries it doesn't need.

Somebody please explain Aws serverless like I am a 5 year old.

Why the fuck are they talking about cold start time and completely reengineering the jvm so that they capture it after it is initialized?

Rube goldberg shit…

The jruby jit compiler is trash. 25 minutes for logstash to show signs of life.

Had to work with SoapUI and accidentally taught myself Groovy.

I found Groovy a very nice language to work with. I've always wanted to do things with the JVM but still don't fully comprehend Java's OOP and stuffs. In which domain is Groovy used widely or intensively? Would anyone recommend me to learn it further?

Frigging jvm crashing god every god dammed time...Here I was all jolly about to start presenting a report to my team , I hadn't exported it to HTML yet so I was presenting in the app . Half an hour goes by and it's all good no problems , manager suggest I export a report and pass it to everyone . The moment I right click jvm HANGS THE APP . I try to save the session file but fail horribly , the temp file only has unreadable , unimportable data...fml now I have to go back through all that from memory...

Java, Scala, Groovy, Kotlin or Closure? Which do you prefer?

If not Java from those above, can you give an example why?

I'm curious what you guys like. If you're not interested in Java, please stay away, it's not about C++ or any other fancy language.

Going crazy with GC logs, HeapDump and ThreadDump😶Application performance issue😬

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.

Here's my opening rant. Websphere Application Server...when restarting your JVM takes so long it should have its own epic on the task board.

#ThingsToDoWhileWASRestarts

Not a dev yet (pretty fucking far from it actually) but I really enjoy coding and learning but I feel like I chose the wrong motive
I started leaning Java because it was easy to find a job since it's very popular and I got the basics pretty well integrated but I feel like I can't really do anything I wanted to do with it, I wanted to build small pieces of software that would run on windows and Linux but the fact that Java needs the jvm to work on a system makes me feel uncomfortable, I don't know why, and that makes me wanna switch to c++ even tho i think it's harder to learn.
I know it's bad practice not sticking to what I learn and pursue it but I don't know what to do with Java...
Any advice?

Sry not really a rant but you guys are the best dev community out there so I figured...

Tldr: feel like I can't do what I want with Java, want to switch to learning c++ and drop Java for now whatcha think?

Any Elasticsearch gurus here? I have a box with too many young gen GCs (one per 2 or 3 seconds), and irregular, very long old gen GCs (One per several hours, taking around a minute and freeing about 2/3's of the old gen space) -- I was thinking changing the new gen ratio from 2/3 to something like 3/4 or 4/5.

However, after reading an elastic article about settings to never touch... I'm no longer so sure...

Only other option I was considering is going from CMS to G1GC to cut back on the old gen GC time... A minute long downtime for Elastic is rather problematic.

Any thoughts? The box is rather old - running Elastic 5.6 with 20 GBs of heap, 207 shards and 306k docs.

Any good podcasts anybody can recommend about jvm-based technologies (Java, Scala etc) and SQL?

It seems Java on Linux runs slower than Windows... Same code takes about 2x longer to run. And well this code is for a batch job...

Does anyone have experience with JVM tuning/optimization or can confirm/disprove this is the case?

Java: creating arrays of a generic type.

Doable but hacky.

Step one to the JVM:

Avoid all NPEs at all costs

I'm trying to create log files with the PID or some JVM arg like app name but File appender doesn't parse ${myVar} in the config.

Issue is we have multiple instances of an app running but they can't be all writing to the same file.

I tried creating a custom Appender by pretty much copying the source code of FileAppender and then adding a function to add PID to the filename.

But when I use it, get some error saying "name, and fileName" are invalid parameters.

So wondering if anyone has experience building one that works out maybe there an existing code for such an appender?

Is it true that Ford Sync UI is made with Flash...?

Java/Maven Question

We have a project with source==target==1.7 in the compile plugin.

But on our servers we actually run it using 1.8 JVM. Is there any reason why we can't see it to compile with 1.8?

Or is it like the Windows backwards compatibility options?

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

Seems like spring boot kotlin doesn't want to cooperate in any way. Tried to set up a backend with it, but it keeps showing an error regarding wrong jvm-target. The project runs nevertheless. I changed the maven settings according to the docs, but no change. Whatever, still runs. However a newly created "hello world" rest endpoint just doesn't work, even following a beginner tutorial. localhost:8080/hello ... error fallback page.
I really wanted to give kotlin a try. Doing the same with java, instantly working.
Fuck spring boot kotlin. Or fuck me for not knowing how to handle it.
