If Programming Languages Were Girls:
Java: Your current girlfriend, you've been going steady for a while now. Things are okay.
Kotlin: The girl Java finds you cheating on, she's just amazing, and you wish you'd met her sooner.
Visual Basic: The girl you accidentally started a relationship with because you didn't know how to say no. But quickly realised your mistake and regretted it.
JavaScript: A childhood friend you occasionally hook up with. But you could never settle for a relationship with them.
Python: A bossy, manipulative girl who quickly turned things sour. But everyone else loves her because of her huge libraries.
-----------------------------------------------------
My and a co worker were joking the other day about what programming languages would be like if they were girls. This is what we came up with (Original inspiration: the Distracted Boyfriend meme (Feel free to add your own!)).49 -
A devDuck update!
Hey everyone,
First off, thank you to everyone who has purchased a devDuck (or a bunch!) and thanks to all who have given us feedback. @trogus and I are thrilled at the incredible response these ducks have gotten. If you haven’t seen them yet, you can check them out at https://devDucks.com or the devRant Swag Shop (https://swag.devrant.io).
We are trying to process all of the orders as quickly as possible and our goal is to have all current orders out by the middle of this coming week. Many orders have already shipped, but if yours hasn’t, rest assured it will very soon!
If you ordered a Java devDuck or cape, your order might be delayed a bit until the middle of this coming week because Java seems to be a heavily-demanded cape and we needed to get the material shipped in to make more of that, specifically.
So far we’ve gotten some awesome feedback from the community. A short list of possible future additions based on what’s been requested: Go devDuck, Kotlin devDuck, Perl devDuck, Android devDuck, and possibly some devDuck accessories like little hats, sunglasses, headphones, etc. If you have any other ideas just let us know:)
Lastly, please know that even with the launch of devDucks, we remain extremely committed to the devRant product and we have some very exciting big devRant features coming very soon.
Thanks again everyone!28 -
Assembly: He’s the nerd. He speaks very quickly and uses short sentences. Very few people talk to him. He’s considered to be an autist asperger by a majority of the class because he finishes the exams so quickly it’s insane and he faces a lot of difficulties in speaking with others. He’s at school but already dressed like an engineer.
Ada: She’s a foureyes nerd. When she gets the answer she’s doesn’t make any mistake. Ada often corrects the teacher when she writes a line a little ambiguous. She’s building a rocketship in her backyard and she’s always speaking about this weird hobby.
Python: He’s Mr Popular. He likes skate, brags about all the parties he’s invited to. He’s good in all the subjects taught in class but he’ll do them a bit slower than the others. Everyone loves him because he explainsthings so well, sometimes the teacher herself asks Python to explain some part of the course. He’s dressed with a hoodie, a baggy and glasses on the top of the head ;)
Java: She is one of the toppers of the class and very popular. She’s very good in all the topics. The teacher loves her but she’s a very talkative person.
Scala/Kotlin: They are twin sisters and the best friends of Java. Unfortunately, they are not as popular and it’s often Java who takes the lead in the group. It’s very difficult to distinguish one from another. Both are far less talkative than Java but Scala speaks a bit differently than Kotlin and Java.
C: He’s the topper of the class. He’s so fast in completing the exams that the teacher really thinks he’s copying Assembly’s work. He has a little brother C++ and they share a lot in common together. He’s the chess major and often plays chess with Assembly and his big brother.
Go: He’s the new kid on the bloc. He doesn’t like C++ and his friends and he wants to prove he can do better than them. Of course, he prefers playing Go over Chess.
APL: He’s a lonely guy. No one understands him when he speaks. Even the teacher is surprised when APL shows a correct answer after several lines of incomprehensible pictograms. People think that he was born in a foreign country… or a foreign planet ?
HTML/CSS: These twin brothers are very different. One is dressed in black and white and the other is dressed with everything except black and white. HTML is very talkative and annoying and the CSS is very artistic. CSS is the best student in Art lessons and HTML performs well in written expression.
LaTeX: She’s friend of HTML. The teacher likes her because she has a gift of writing. LaTeX likes the mathematical courses because she can draw fancy greek letters. The teacher knows this well and she is often asked to write a formula on the black board.
VBA: He’s in the back, looking through the windows. Not really interested in the courses taught in class. In the exams, he answers always with a table.
C#: He’s in the back playing yet another game on his smartphone. He likes being next to the windows also.
JavaScript: People often mix up Java and JavaScript because they have a similar name. But they are definitly not the same. Javascript spends a lot of time with HTMLand CSS. He’s as artistic as CSS but he prefers things that move. He likes actions and movies. CSS dreams to be a painter wheras JavaScript wants to be a film-maker.
Haskell: He’s a goth. Dressed up in dark. Doesn’t talk to anyone. He doesn’t understand why others write pages when he can write a couple of lines to answer the same question.
Julia: She’s the newest student here. She doesn’t have any friends yet but her secret aim is to be as popular as Python and as fast as C.

I'm 20, and I consider myself to be as junior as they come. I only started programming seriously in June 2016,and since then, I've been doing mainly Android Work, and making my own servers and backends(using AWS/Firebase nd stuff).
For the first time in life, I was approached by a recruiter for a company on linkedIn. They "stumbled upon" my Github profile and wanted to see if I was interested in an internship opportunity. This company is an early stage start up, by that I mean a dude with an idea calling himself the CEO and a guy who "runs a tech blog" and only knows college level C programming (explaination follows).
So they want me to make the app for their startup. and for that, I ws first asked to solve a couple problems to prove my competence and a "technical interview" followed.
They gave me 3 questions, all textbook, GCD of 2 numbers, binary search and Adding an element to the linked List, code to be written on a piece of paper. As the position was that of an Android Developer, I assumed that Java should be the language of choice. Assumed because when I asked, the 'tech blogger' said, yeah whatever.
But wait, that ain't all, as soon as I was done, Mr. Blogger threw a fit, saying I shouldn't assume and that I must write it in C. I kept my cool (I'm not the most patient person), and wrote the whole thing in C.
He read it, and asked me what I've written and then told me how wrong I was to write 2 extra lines instead of recursion for GCD. I explained that with numbers large enough, we run the risk of getting a stackoverflow and it's best to apply non recursive solution if possible. He just heard stackoverflow and accused me of cheating. I should have left right then, but I don't know why, I apologized and again, in detail explained what was happening to this fucktard. Once this was done, He asked me how, if I had to, I'd use this exact code in my Android App. I told him that Id rather write this in Java/Kotlin since those are the languages native to Android apps. I also said that I'd export these as a Library and use JNI for the task. (I don't actually know how, I figured I can study if I have to).
Here's his reply, "WTF! We don't want to make the app in Java, we will use C (Yeh, not C++, C). and Don't use these fancy TOOLS like JNI or Kotlin in front of me, make a proper application."
By this I was clear that this guy is not fit to be technical lead and that I should leave. I said, "Sir, I don't know how, if even possible, can we make an Android App purely in C. I am sorry, but this job is not for me".
I got up and was about to leave the room, when we said, "Yeah okay, I was just testing you".
Yeah right, the guy's face looked like a howling monkey when I said Library for C, and It has been easier for me to explain code to my 10 year old cousin that this dumbfuck.
He then proceeded to ask me about my availability, and I said that I can at max to 15-20 hours a week since my college schedule is pretty tight. I asked me to get him a prototype in 2 months and also offered me a full time job after I graduate. (That'd be 2 years from now). I said thank you for the offer, but I am still not sure of I am the right person for this job.
He then said, "Oh you will be when I tell you your monthly stipend."
I stopped for a second, because, money.
And then he proceeded to say 2 words which made me walk out without saying a single word.
"One Thousand".
I live in India, 1000 INR translates to roughly $15. I made 25 times that by doing nothing more than add a web view to an activity and render a company's responsive website in it so it looks like an app.
If this wasn't enough, the recruiter later had the audacity to blame me for it and tell me how lucky I am to even get an offer "so good".
Fuck inexperienced assholes trying shit they don't understand and thinking that the other guy is shitsworth.10 -

Person 1: oh my God this man here is having a heart attack. Is there a doctor here?
Person 2: here's ten reasons why Kotlin is better than Java for Android development5 -
A is for Assembly, a wizard's spell
B is for Bootstrap, so bland and the same. And also for Brainf*ck, will blow you away
C is for COBOL, your grandad knows that
D is for daemon, your server knows what
E is for Express.js, you node what is coming
F is for FORTRAN, which is perferct for sciencing
G is for GNU which is GNU not UNIX
H is for Haskell using functional units
I is for Intance, An action of Object
J is for Java plays with them Always
K is for Kotlin, Android's new toy
L is for Lisp, scheming a ploy
M is for Matlab, who knows how it works
N is for Node a bloatware of code
O is for Objective Pascal, you did not expect that
P is for programming, we all love to do that
Q is for Queries, A database is made
R is for R, statistics are great
S is for Selenium, you have to test that
S is for Smalltalk, let's make it all brief
T is for Turing Test, how human is this?
U is for Unix, build with all talents
V is for Visual Studio, built with all laments
W is for Web, lets build something cool

Interviewer : So what frameworks and library you usually use?
Me : i use volley for networking, gson for parsing, livedata/architecture components for architecture and observability , room for database and java for app development
I : ok so make this sample app using retrofit for networking, moshi for parsing, mvrx for architecture , rx for observability , sqldelight for db, dagger2 and kotlin for app dev. You have 8 hours
Me :(wtf?) But i never used those libs or language!
I : we just want to check how easily you adapt to different surroundings.
Me : -_-
Honestly i don't know of it was a great experience or a bad one . I was stressed the whole time but was able to adapt to almost all of those libraries and frameworks.
At the end i got selected but decided not to go for those ppl. That was just a lucrative opening of a venus fly trap, they would have stressed the hell out of me11 -
I just started learning Kotlin for a week or two and suddenly Google announced Kotlin will be officially supported for Android development.
I'm excited.6 -

Yahoo, Kotlin is the first class language for android. So no more fucking Java codes. No more 100 lines for basic configurations. No more null pointer exceptions.
Only beautiful code and fun.14 -
Friend: Hey, so what do you do?
Me: I build backend systems and apis. I work with java/mongodb. I dable into some elixir and kotlin on my free time.
Friend: Cool, can you build me an Android app?11 -
Frustrated, tired and a bit lost.
I'm a "Senior PHP Backend Dev", which includes not the greatest tech stack nor the best job title, but it pays fine, and the company is awesome to work for.
I suck at writing features, but I'm great at bitching, and I easily put complex abstract concepts into usable models. So I'm also QA, tester, tech lead, database architect, whatever.
That makes writing PHP less annoying, because I create the rules, and whip devs around when they forget a return type definition or forget to handle an edge case. But I don't write a lot of code anymore, I mostly read (bad) code.
Lately I REALLY feel like doing something else... problem is that I know JS/ES6, but really dislike React/Vue and the whole crappy modern frontend toolchainchootrain of babelifyingwebpackingyarnballs. I know Python/Tensorflow/etc, but don't feel like I want to go into data science or AI. And then I'm awesome at the shit no one uses, like Haskell, Go and Rust (and worse).
I got a job offer which combines a very interesting PHP codebase with a Java infrastructure, where I could learn a lot... and I'm kind of tempted.
Problem is, everyone always shits on Java. I always made a bit of fun of Java myself. Don't even know exactly why, probably some really cruel instinct which causes kids to bully the least popular kid.
I know the basics, I've written the hello world, and a small backend app for a personal project. I know how strict and verbose it can be. I love the strictness in Haskell and Rust.... but those are both also quite terse.
Should I become a Java dev? I'm not talking about Android SDK, but an insane enterprise codebase at a life sciences corporation.
To the pro Java devs: What are the best and worst things about your job, about the weekly processes, about the toolchains? Have you ever considered other languages? Do you unconditionally love and believe in Java, or do you believe Swift, Kotlin, Scala or whatever will eventually make it completely obsolete?
Will Java hasten my decline into the cynical neckbeard I was always destined to be?
There are a lot more fun langauges, but looking at realistic demand and career value...20 -
I seriously wanna fucking knofe this guy who says JS is shit and Kotlin is superior well NEWS FLASH YOU FLYING PIECE OF WANK, every fucking language has its pros and cons
If you still think JS is supposed to be in browser well I say to you fucktard this isnt the 80s anymore and we ain't using Java applets and Flash for some limp dicked stuff JS has covered today. A language might have its dark sides but they are all fucking good. There is no superiour language there's only Mother fucking preference. I swear to god this is the worse limp dicked argument I've heard and I have to argue that JS has matured over the years11 -
Android really gets on my goat. They are moving things so far that they are actually doing more damage than good.
Upgrade my build tools to v25? sure! Now all my BLE code is borked, thanks for nothing.
Go to the documentation? Lol, that's deprecated fool!
At least now it can all fail to function in Kotlin, a wrapper for Java 6. Instead of keeping your tools up to date you just create another layer of obfuscation. Well done, so proud.3 -
So I've decided to go about converting a Java project that I've been working on to Kotlin a little bit at a time. I started out with basic entity classes converting them to simple `data class`es in Kotlin.
Eventually, I got to my first beast of a class to refactor. This class had over 40 service classes depending on it, so even a little hiccup would throw everything into chaos.
I finish all of the changes on all of the dependent classes, update the tests, and the configurations (as necessary), and I was finally ready to spin up the app to test for any breaking changes I may have introduced...
Well - I broke everything! But I was sure I couldn't have! So what the hell happened?
Turns out that as I was building my project with a Gradle watch, at one point something failed to compile, which threw an unhandled exception in the gradle daemon that was never reported.
So when I tried to run my app, gradle would continually re-throw the error in the app I asked it to run...
After turning the daemon off and on again, the app worked like a charm.10 -
IntelliJ!! In my opinion its the best IDE for Java and Kotlin and it supports you to code better
And I got it for free because I'm a student :D4 -
Kotlin
All the languages have a basic objective in mind that shapes both the language and it's community:
for c/c++ was low level hardware access and performance, for Java OOP and learning; Kotlin was mostly made to make dev life easier and tries to anticipate what you want to do instead of forcing his patterns and tries to help you instead of punishing errors.
As a dev at least i feel a little more cared about and less left alone (especially in the ugly world of Java for Android)14 -
Porting Java Code to Kotlin manually, just to get a better understanding of the language. Best thing so far, NO more Assertive Exception Handling.
Damnit Java, I know it for a fact that the damned thing won't throw an exception! There's Careful and Paranoid. KNOW THE DIFFERENCE5 -
When I was first learning Kotlin, I was so excited about its simpleness and power compared to Java.1
-
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...14 -

Does anyone feel overwhelmed by all the new technologies? It's like every developer nowadays code in JS, and knows ES6, React, webpack, babel by heart. I have been working in Java for less than a decade and sometimes feel like I can't catch up. Even in Java ecosystem there is now Scala, Groovy, Gradle, Kotlin... Not to mention other languages like Python, Swift... How do you guys have time to pick up everything?? 😖7

Truth: You will regret not using Kotlin as soon as possible. Don't deprive yourself of pleasant development and productivity boost.5

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.12 -
I just read a rant about Java by a guy who moved from JS/python.
FFS, until now you were using some aberration of OOP by creating "objects" and making them however you want instead of sticking to concept of blueprinting and managing your classes in a way shit happens properly.
Yes, I do hate js/python-like langs if I would have to do something big in them, because I need to constraint my program so it works predictably every time. I don't feel like I'm doing that by putting some arbitrary key-value pairs into some random object :v
Java and her sexier sister Kotlin ftw and nothing gonna change my mind <315 -
I'm a backend (Java, Kotlin) developer and I mainly design & develop services and Android apps which consume these services.
My team in my current organization (I've been working here since past 2 years) just got merged with another team.
And now the new boss wants me to fix some fuck ups in their project which is written in C#, with some WCF and other stuff.
As this stuff is completely new for me, I asked for some time to get familiar with the environment. But the answer was a big NO.
As a result, "I've started looking out for a new job"
😡😠
Fuckin management screws up everything!4 -
Why do job descriptions for ONE developer position, list down ALL the known programming languages, all the web technologies and frameworks available? From java kotlin swift php js jquery node to ionic angular laravel python and what not. Wtf? And this is not one, this is about 70 percent of the job descriptions I see these days!!5

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!2 -
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/Java12 -
TL;DR Pluralsight should be ashamed for taking 299 USD a year and writing some very low-quality quizzes.
I've always heard that Pluralsight is a great platform having some high quality courses, so I chose it as a benefit, as our company was giving us some budget for learning purposes. I've paid (or rather the company did it in the end) 299 USD for this year, which, I guess is not much for US standards, but it is a lot for Eastern European standards.
I didn't actually get to the point of watching any of the courses, but I started to use a feature called "Stack up", which is a long series of questions in a specific theme, like Java, Kotlin, C++, etc., accessible once a day. I must say, I'm amazed by the fact, that people pay quite a great amount of money and they get something so poorly made with a lot of errors and stupid questions.
Take the question from the included image for example. Not only that the 2 possible answers are repeated (and thus I failed to select the correct one from 2 equal answers), but the supposedly correct answer is also missing some type specifications. No Java compiler will compile it this way as far as I know. There would be at least 3 ways to fix it.
Then there is today's gem (should be included as first comment) as well, where the answer is wrong in both Chrome 96, Firefox 95 and Node v10. Heck, THIS IS one of the reasons why you should never use `var` in your JavaScript code, but always `let` and `const`!
So the courses on Pluralsight might be good, but I would be ashamed, if I were to release something like this. People might actually try to solidify their knowledge by solving these quizzes but instead of learning something useful, they will be left with some bullshit. I just don't get how could they release a feature with so much incorrect information and I am kind of disappointed, even if I didn't try the courses yet.9 -
Still tryin to learn Java and suddenly appears Kotlin... I sometimes want to stop the frig world :'v5

hi guys, i'm django developer and i wanna learn android.
should i choose kotlin over java?
how is job vacancies?22 -
Main language, do people have such a thing? Some quixotic shit about various languages I use:
C#: Microsoft
F#: never quite committing to 100% functional paradigms while still being one of the most enjoyable langs I use
Java: null handling via optional and maybes are ugly, but better than it was
C++: surprisingly functional in 2020
Haskell: no one else seems to ❤️ it, despite it being fucking beautiful
Kotlin: Ternary warfare, Czech sports opinions on how languages should work
Clojure: parenthetical scoping makes me far happier than it should
Typescript: makes ever more sense as it changes7 -
Kotlin support on Android:
i never liked Java, not because of the language but for the usual bad design implementations and Android is one of those.
Then Kotlin arrived, it looked very promising but it's when i looked at Coroutines that it simply blew my mind:
you just have to write your code and the Kotlin's compliler "magic" will do most of the boring/complex stuff for you and it's even great performance wise!
I even refactored inter-process calls to simple sync functions with few like of code and for a non-android developer like me it's just love at first sight!3 -
I have to say, Kotlin is getting interesting now. At first i was like "WTF is this shit", but now im like "TF, did i just create a data class with 2 lines of code as opposed to the 14 i would have using JAVA? TF you've been Kotlin?"

Kotlin makes the development experience so much better. Humans are creatures of habit. Some don't want to change what they already know. RIP to those who still start their project in Java and do not want to adapt in this competitive world. :/8

Working with atlassian products....
Possibility 1
You can either use exactly this one way and only with these specific instructions ...
Which will certainly not work for the project you have.
Possibility 2
There is an feature request which gets ignored for years, someone made a plugin...
But plugin was removed as inactive. :-)
Possibility 3
Atlassian provided in their endless graciousness a plugin.
After hours of deciphering Kotlin / Java code as the documentation is either useless or lacking details...
You did it. You got the REST shit working.
Well.
You just needed a script which wraps the underlying command, parses the commands well defined format like XML with specification.... To a completely gobbled up JSON, that looks like undecipherable shit.
I really hate Atlassian.
https://bitbucket.org/atlassian/...
I just wanted to add code coverage via the REST API by the way.
A really unnecessary and seldomly used future as it seems.
And yeah... The JSON contains a coverage element which contains a semicolon separated key value store, value being a comma separated list of line numbers....4 -
More like a sub company/department inside a company: Android.
I still use it as my main driver, but every time I try to get back into development with it(did it professionally for 2 years nearing on 3 and was a lead Android dev, mind you not necessarily by merit....) I end up hating everything about it.
The tooling is meh, the API is hideous and even with the addition of Kotlin, which I do find a nicer language over Java I still dislike it. The ammount of shit needed to make something as simple as store data, manage fragments, integrate with the NDK, make JSON API calls or even shake motions is just ludicrous and counter intuitive. I can see why people would hate Java based on Android, a language that I generally love and defend.
I firmly believe that people extend frameworks or tooling for 2 reasons only:
1 the stack is so awesome that you just want to create packages and libraries to extend the functionality of a powerful environment, like gems for Ruby, python packages, Node packages, php composer, nuget etc
2 the stack is so fucking hideous that people need to fix shit: the entire android square utility framework, butterknife, flutter, react native, codenameone, etc etc
The case with Android is the second. I have not met a professional Android developer that completely likes everything about Android, but will seldom find people that HATE other frameworks or environments.
Android it is for me. Still my daily driver and I love every Android phone I have ever owned. It just makes me feel lots of more compassion for fellow Android devs.4 -
I laughed waaay to hard at this. Anyone using kotlin? The language seems really nice, i currently develop with React Native if I can avoid java on android (too much to do too little) and was thinking about kotlin.2

Goodbye Java I will not miss you at all! I swear ...
I do like it when making web services (especially that I can use Java8) but for Android you have been a torture. Hello sweet Kotlin! I shall embrace you and treat you like my newly born baby!!
Story is:
Working on a new project where I need to talk to a web service (also made by me).
Started writing in Java, all is cool and unit tests pass.
Downloaded Android Studio 3 Beta 1 and converted my Java code to Kotlin, That AsyncTask did not look nice in kotlin, converted it to async & await feature and I must admit lots of code removed, no more need to create a new fucking AsyncTask every time the app sneezes for data!
I feel like I'm working with C# but with difference in syntax.
My life is now complete :)undefined java goodbye! am i drunk? koline: sorry i have a boyfriend hi there kotlin i shall not miss you what the fuck did i just use for a tag?8 -
- finish the app for my school
- FUCKING finish the google scholarship before time ends ._.
- learn git
- build a home fileserver, like a own cloud, which can be accesed even further away (has any one some tips on how to do it? ^^)
- attach a gps tracker to my moped, which I can then see on a mobile app (because I don't want it to be stolen...)
- rebuild my homevillages website
- learn python
- replace my android Java with kotlin
- apply to an internship for a software design company
- more and more and more
uff. ._.''
Hope you guys will have a nice and PRODUCTIVE 2018! :^)10 -
Why is flutter so unbelievably awesome?
It makes development soooo much quicker and easier compared to native java/kotlin/swift...so much simpler on so many levels, that it still feels somehow ..*wrong*...to me....10 -
Next week I'm starting a new job and I kinda wanted to give you guys an insight into my dev career over the last four years. Hopefully it can give some people some insight into how a career can grow unexpectedly.
While I was finishing up my studies (AI) I decided to talk to one of these recruiters and see what kind of jobs I could get as soon as I would be done. The recruiter immediately found this job with a Java consultancy company that also had a training aspect on the side (four hours of training a week).
In this job I learned a lot about many things. I learned about Spring framework, clean code, cloud deployment, build pipelines, Microservices, message brokers and lots more.
As this was a consultancy company, I was placed at different companies. During my time here I worked on two different projects.
The first was a Microservices project about road traffic data. The company was a mess, and I learned a lot about company politics. I think I never saw anything I built really released in my 16 months there.
I also had to drive 200km every day for this job, which just killed me. And after far too long I was finally moved to the second company, which was much closer.
The second company was a fintech startup funded by a bank. Everything was so much better than the traffic company. There was a very structured release schedule, with a pretty okay scrum implementation. Every team had their own development environment on aws which worked amazingly. I had a lot of fun at this job, with many cool colleagues. And all the smart people around me taught me even more about everything related to working in software engineering.
I quit my job at the consultancy company, and with that at the fintech place, because I got an opportunity I couldn't refuse. My brother was working for Jordan Belfort, the Wolf of Wallstreet, and he said they needed a developer to build a learning platform. So I packed my bags and flew to LA.
The office was just a villa on the beach, next to Jordan's house. The company was quite small and there were actually no real developers. There was a guy who claimed to be the cto of the company, but he actually only knew how to do WordPress and no one had named him cto, which was very interesting.
So I sat down with Jordan and we talked about the platform he wanted to build. I explained how the things he wanted would eventually not be able with WordPress and we needed to really start building software and become a software development company. He agreed and I was set to designing a first iteration of the platform.
Before I knew it I was building the platform part by part, adding features everywhere, setting up analytics, setting up payment flows, monitoring, connecting to Salesforce, setting up build pipelines and setting up the whole aws environment. I had to do everything from frontend to the backest of backends. Luckily I could grow my team a tiny bit after a while, until we were with four. But the other three were still very junior, so I also got the task of training them next to developing.
Still I learned a lot and there's so much more to tell about my time at this company, but let's move forward a bit.
Eventually I had to go back to the Netherlands because of reasons. I still worked a bit for them from over here, but the fun of it was gone without my colleagues around me, so I quit last September.
I noticed I was all burned out, had worked far too much, so I decided to take a few months off and figure out what I wanted to do with my life. I even wondered whether I wanted to stay in programming.
Fast forward to last few weeks. I figured out I actually did want to work in software still, but now I would focus on getting the right working circumstances. No more driving 3 hours every day, no more working 12 hours every day. Just work close to home and find a company with the right values.
So I started sending out resumes and I gave one recruiter the chance to arrange some interviews too. I spoke to 7 companies in the span of one week. And they were all very interested. Eventually I narrowed it down to 2 companies and asked them for offers. And the company that actually had my preference offered me significantly more than I asked for, which settled the deal.
So tomorrow I'm officially signing with them, and starting next week I'll be developing in Kotlin, diving into functional programming and running our code in serverless environments. I'm very excited! -
Just switched to Kotlin.. For the first like 10 minutes I was like "What is this shit?!" and then I found Java to Kotlin converter and docs. Yay! Looks like it´s not gonna be that hard to do some apps in it.. Hopefully4

Sorry, need to vent.
In my current project I'm using two main libraries [slack client and k8s client], both official. And they both suck!
Okay, okay, their code doesn't really suck [apart from k8s severely violating Liskov's principle!]. The sucky part is not really their fault. It's the commonly used 3rd-party library that's fucked up.
Okhttp3
yeah yeah, here come all the booos. Let them all out.
1. In websockets it hard-caps frame size to 16mb w/o an ability to change it. So.. Forget about unchunked file transfers there... What's even worse - they close the websocket if the frame size exceeds that limit. Yep, instead of failing to send it kills the conn.
2. In websockets they are writing data completely async. Without any control handles.. No clue when the write starts, completes or fails. No callbacks, no promises, no nothing other feedback
3. In http requests they are splitting my request into multiple buffers. This fucks up the slack cluent, as I cannot post messages over 4050 chars in size . Thanks to the okhttp these long texts get split into multiple messages. Which effectively fucks up formatting [bold, italic, codeblocks, links,...], as the formatted blocks get torn apart. [didn't investigate this deeper: it's friday evening and it's kotlin, not java, so I saved myself from the trouble of parsing yet unknown syntax]
yes, okhttp is probably a good library for the most of it. Yes, people like it, but hell, these corner cases and weird design decisions drive me mad!
And it's not like I could swap it with anynother lib.. I don't depend on it -- other libs I need do! -
So today I decided to try out Kotlin on Android. Hacked up a little Textview-Button app. AMAZED with the little code.14

Tried flutter for the first time in life, for 2 days, java based Android dev here.
I have some.... thoughts...
Flutter does not feel extremely new to me. It is very much relatable if you have ever tried basic the spring/ other java based gui framework. It is trying to achieve the goods from multiple worlds,its so far good, but mann its playing on thin ice.
Flutter : Yo boy embrace me. I am the beauty. checkout my hot reload.
Me :❤️❤️😍 (But wait. your first execution is wayy longer than a simple android studio build. And AS would generally take smaller time after every rebuild. And you are going to take the same long time as first build, if app gets closed or my usb gets accidentally removed. So I see what you did there ;))
Flutter: Ha. Checkout my function passing as parameter. ever thought your puny java going to give you that?
Me :you got me ,❤️. (Although this style is not so uncommon with web devs)
Flutter: everything is a widget, everything is stateful or stateless, Single Streams FTW!
me: ❤️
Flutter:You kotlin devs are gonna love me, i got Small, concise code
Me: Now wait, This is a thin ice for me, okay? I hated when kotlin replaced everything with symbols & lamdas for a confusing but small code, So be careful,even though your code is still good.
Flutter : Control every pixel , dear! No more xmls!
Me : Yes, what is with that? are we accidentally going in the past?
Java desktop apps, spring framework used to build whole layouts with programming language. The day i stepped into Android, it was xml for ui and java/kotlin for code. was that a bad decision or is this one?
Anyways i liked my stuff seperated, but that's just me.
Flutter : Ugh so much whining. Are you going to work with me or not?
Me : Yes mam! ❤️4 -
I just felt like Google is the best player out there in terms of Companies.
Seriously, Well played Google.
This is not a negative opinion, I am just awe-struck at its tactics.
See, Google is currently the biggest name in terms of development in Android, ML and multi-platform software but no one can say it being a monopoly due to its dedication to open source community.
Recently Android emerged out to be One of the Biggest , most advanced, trusted and loved Technology . It saw great achievements, and up till 2016-17, it was at its peek. BUT when the market started shifting towards multi-platform boons and Ai, it got its hands into that too with its flutter and kotlin environment
One could have a negative opinion about this, But i can't seem to engulf the vast amounts of positive situations i see in this:
1) this IO18 (and many months before that) saw ML/AI being incorporated in Android (also the arcore, proje tango and many more attempts in the past) meaning that Android will not officially "die". It will just become an extremely encouraged platform( not just limited to mobiles) and a beginning of the robot -human reality ( a mobile is handling everything of your everyday life: chats, music apps sxhedules, alarms, and with an actively interacting ML, it won't be long when Android comes installed in a green bug lime droid robot serving you tea xD). Meanwhile the market of Windows games may shift to mobiles or typically " Android games" (remember, Android won't be limited to mobiles)
2)java may or may not die. The animations and smooth flow it seems to provide is always appreciated but kotlin seems to do so too. As for the hard-core apps, they are usually written in c++ .So java is in the red zone
3) kotlin-native and Flutter will be the weapons of future , for sure. they will be developing multi-platform softwares and will be dividing the market of softwares into platform specific softwares(having better ml/ai interactions,animations) and platform independent apps(access and use anywhere softwares).
And where does google stand?Its the lord varys of game of thrones which just supports and enhances the people in the realm. So it benefits the most . That's a company for you, ladies and gentlemen! If seen from common eyes they seem to be the best company ever and our 1 true king but it can also be a very thick fur cloak hiding their negetive policies and tactics , if any.
Well played, Google.16 -
"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. "
LOL6 -
I was a Project Manager, studied my a$$ off at 38 to become a mobile developer. Built production apps in Java, React Native. I've studied Kotlin and Flutter. Then my company almost went belly up and I had to scramble to find a job to support my family. Back to being a PM which I hate. Started with Swift because my son is old enough to play with Swift Playgrounds and thinking about making a break back into dev. Every post I see on Twitter is about Flutter, maybe RN, but not much Native iOS. Is it wrong that I'm loving it thus far? What's the future for Native iOS and Android developers?5

Working with the Android SDK after about a decade of mostly avoiding ever having to do so directly...and fucking hell, nothing has changed.
It's still obtuse as fuck, you constantly have to provide contexts to operations which can't need them (there's only one fucking keyboard to close), and whilst they have added some new stuff which helps like Material, the APIs are just as mental, the setup just as elaborate and manual - and they don't seem to have deprecated anything along the way, so fifteen years of random software design decisions cohabit awkwardly together like the Bucket family.
I don't really mind Java, it's just long-winded C - but boy has it found its niche here. Your code is more boilerplate than not until you've written more than you'll mostly ever need to for an app.
At this point I'm just laughing when I come across another Stack Overflow solution for a trivial operation that involves writing an entire class. I would try Kotlin but this isn't a new project, and I'm not pissing another ingredient into this hot mess.
Alright, Android Studio is an improvement on Eclipse, but that's not really saying much.3 -
Question:
Kotlin?
Yes || No || Donno
Thinking about giving it a small touch but wanted to look on what others thoughts are.

After 1 year of working as android dev and coding in java, finally switched to another startup where everything is in Kotlin where I will be the only one maintaining that project.
Me: This code has almost no comments
Senior dev: Code is pretty self explanatory
FML
At least she spent 4 days with me and walked me through the code, so I'm not totally lost which is great!2 -
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.8 -
had to create a rather large CLI based application in Java as a graduate level assignment.
Doing shit like this makes me appreciate Node/Python/literally fucking anything else much more for this shit in which storing and retrieving JSON does not have to be that much of a fucking hassle WITHOUT using external libraries(they want it all made by hand)
I love Java, don't get me wrong, but I would rather use it for only a couple of things. I stopped working as a Mobile dev precisely because of Android being shit for Java. No, Kotlin does not fix it, its not the language that is my problem, its the fucking general architecture of the Android API that pisses me off.
And no, I do not care if you like it, like 1 fucking bit. I am not saying that the architecture is shit, I am saying that I did not like it.
Sigh.......oh well. Almost done with the assignment, but still.7 -
better late than never.
So I just decided to go with Gitlab after being a Microsoft Team Services user.
To do next on my list:
Move away from .Net for backend services, any suggestions? I use dotnet core due to being able to easily finish what I want and with less code to write. Tried Springboot for Java but not a Java fan, might checkout kotlin though17 -
I started with C#at the age of 12, it was way too complicated and I learned Lua for Computer craft instead. Next I learned Ruby for RPG Maker and finally Javascript for web Dev stuff.
Now comfortable enought with Javascript but put off by its quirks I learned Java for compiling faulty minecraft mods, but I only fully learned it in school.
At the same time I learned python and quite liked it for scripting, but ultimately it was not a good match for my projects.
Disapointed with Java I returned to C# and liked it quite a lot, but started learning C++. After touching my first Microcontroller I learned C and I've stuck with it as my favorite language.
Along the way I picked up Kotlin, in case I need to do some Java shit. Much better.
But how did I come to an understanding of programming. Well I got better after each time I got a layer deeper until I hit silicon.
I had tinkered with electronics since I was 15 so I just had to study some boolean mathematics in school and some vintage computers architecture and instruction sets and...
Then I finally understood how that shit I wrote in Lua way back when was actually executed by my hardware.
Allways dig deeper and you'll find enlightenment eventually. -
Why the heck would you allow (or need) nested block comments? Imo this is a major design flaw in the kotlin linter.
I always use /*... //*/ so I can remove the comment starter w/o having to remove the comment end, but kotlin just starts a second, nested comment there.
Java, C, Cpp, C#, JS,... Not one of these uses nested block comments. I think jetbrains was just lazy?
I mean, I know why such stuff happens. I also developed DSLs in MPS, but there sure are ways to go around such things..7 -

I’ve got to build an app in 3 weeks that handles basic image editing and async requests. It’s gotta support both iOS and Android.
It’s also gotta scan barcodes.
What should I use?
Cordova?
Cordova+ionic?
Titanium?
Xamarin?
Dart/flutter?
Try and cram it through in native java/Kotlin and swift?
Something I’m missing?7 -
Android Studio has been the bane of my life for at least the last decade. I hate it beyond description and have given up hope that it will ever improve.
I suffer more than most with it because I am cursed to use C++ on a daily basis, and it has long been obvious that the Google people absolutely do not give a fuck about C++ users.
I get that C++ is niche, a drop in the ocean of Java/Kotlin-centric users, but for the love of god could you Google people at least stop making it worse?
Code navigation is insanely slow. Entire minutes for it to find the right header file to open. "Find usages..." oh my god oh my god oh my god just fucking kill me now. There is no excuse for software ever being this slow.
And thats just doing basic source editing. The build system - cmake and ndkbuild - also defy adequate description. The gradle plugins are constantly going out of date and are often incompatible with whatever gradle version you have. You get no help at all when editing a gradle build file and good luck finding the right documentation.
It's all a giant stinking mess and I wish the whole damn thing would be dragged outside and shot.11 -
I don't get it.
I tried Kotlin on Android just for fun, and it doesn't support binary data handling, not even unsigned types until the newest version. Java suffers from the same disease.
How does one parse and process binary data streams on such a high end system? Not everything is highlevel XML or JSON today.
And it's not only an Android issue.
Python has some support for binary data, and it's powerful, but not comfortable.
I tried Ruby, Groovy, TCL, Perl and Lua, and only Lua let's you access data directly without unnecessary overhead.
C# is also akward when it comes to data types less than the processer register width.
How hard can it be to access and manipulate data in its natural and purest form?
Why do the so called modern programming language ignore this simple aspect that is needed on an everyday basis?10 -
Hi guys, I got some questions for you:
I'm a 17 years old guy from south Italy with 5 years of programming experience, mainly with Java and Kotlin. Since finding a well paid job here is soooo hard (especially when it comes to IT), I will surely go to another country (England, Sweden, Denmark and Norway in my list) once I get my scientific high school diploma. Here are the questions:
1) I have very high skills on JavaFX, both front-end and back-end. Is JavaFX commonly used in companies? Or should I move to other technologies like Android?
2) Will my diploma (plus a good amount of open source projects) be enough to find a job?
3) What certified English level is commonly required in these countries?5 -
I am so 😢🤒😡 right now. I applied for a remote job, so they gave me an assessment and the language was c++. The funny thing is that c++ was not in my resume.
So I decided to explore c++. "I don't know what the fuss is, C++ is not so hard". It was very easy for me to grasp. It took me two days to understand it.
Then I did one of those online test and I scored 58/60.
Now I went back to take the assessment test on C++ but lo and behold the assessment is now on Rest API.
But Rest API is also not on my resume. They are not assessing me on my strengths like Java or kotlin or python or my my lesser strengths like C# or JavaScript.9 -
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 this7 -
At the Android Developers under us:
Do you prefer the new Kotlin language or the good old Java? Because i'm currently learning Android Development with Java.
Would like to hear your opininion! :)5 -
Great googly moogly is Kotlin an ugly language.
If you are just starting out with Android or Java development in general, I highly recommend sticking with Java and avoid Kotlin like the plague. It feels like a meme language that was taken a little too seriously.
Full of little flowery nonsense that aims to make the language more human, but only serves to make it look like a child designed it.
I absolutely hate when a language doesn't require type declarations.
The "it" keyword rankles my underwear beyond belief.
Trying to build a dictionary/hashmap/hash felt like I was writing out an essay for school. In other languages it's straightforward and makes sense. Even PHP makes more sense.
I am obviously missing something here, because there is no way something so common and done the same way across different languages has such a wildly different approach in Kotlin.
I have as much experience with Java as I do Kotlin but it immediately makes more sense as a language and doesn't have all this flowery nonsense. It is verbose, which means I don't have to decipher what the code is actually doing when I read it.
I'm familiar with the enterprise Java meme, but I'm not writing enterprise Java, and that's not my style anyway so it doesn't affect me. But even so, that would be a million times easier to handle that Kotlin.14 -
Because almost all the answers from stackoverflow are still optimum, even if it's 7 year old code, all it needs is some good ol' spit shine refactoring
-
Started playing around with Kotlin and holy shit! It feels like java and js had a baby, but it's actually not a brain-dead pile of crap and works well. I'm sold!
-
Haha, fuck you kotlin! and your null safety!
I was able to break it 😆
After reading about its syntax for over 2 weeks , i finally sat down to write a simple parsing app completely in kotlin. And now i don't know how, but i am able to store a null in a "val x:String" (i.e a non null variable)
I am not going to claim it as some miracle or discovery as some other ranters, it might be a mistake. I am just a 21 yo Android/java dev trying to re write my old ,tested java code to kotlin by myself, without any auto convert, in the middle of night when i am 99% asleep by brain.
I will try to raise an SO question with details, but all i used was a simple volley request returning heterogeneous data, a gson convertor and a single activity,
Right now i am buzzing off to my sleep11 -
Hi everyone,
I'm a senior developer who wants to learn android development.
In your opinion, should I start with java or kotlin?38 -
This started as an update to my cover story for my Linked In profile, but as I got into a groove writing it, it turned into something more, but I’m not really sure what exactly. It maybe gets a little preachy towards the end so I’m not sure if I want to use it on LI but I figure it might be appreciated here:
In my IT career of nearly 20 years, I have worked on a very wide range of projects. I have worked on everything from mobile apps (both Adroid and iOS) to eCommerce to document management to CMS. I have such a broad technical background that if I am unfamiliar with any technology, there is a very good chance I can pick it up and run with it in a very short timespan.
If you think of the value that team members add to the team as a whole in mathematical terms, you have adders and you have subtractors. I am neither. I am a multiplier. I enjoy coaching, leading and architecture, but I don’t ever want to get out of the code entirely.
For the last 9 years, I have functioned as a technical team lead on a variety of highly successful and highly productive teams. As far as team leads go, I tend to be a bit more hands on. Generally, I manage to actively develop code about 25% of the time to keep my skills sharp and have a clear understanding of my team’s codebase.
Beyond that I also like to review as much of the code coming into the codebase as practical. I do this for 3 reasons. I do this because as a team lead, I am ultimately the one responsible for the quality and stability of the codebase. This also allows me to keep a finger on the pulse of the team, so that I have a better idea of who is struggling and who is outperforming. Finally, I recognize that my way may not necessarily be the best way to do something and I am perfectly willing to admit the same. I have learned just as much if not more by reviewing the work of others than having someone else review my own.
It has been said that if you find a job you love, you’ll never work a day in your life. This describes my relationship with software development perfectly. I have known that I would be writing software in some capacity for a living since I wrote my first “hello world” program in BASIC in the third grade.
I don’t like the term programmer because it has a sense of impersonality to it. I tolerate the title Software Developer, because it’s the industry standard. Personally, I prefer Software Craftsman to any other current vernacular for those that sling code for a living.
All too often is our work compiled into binary form, both literally and figuratively. Our users take for granted the fact that an app “just works”, without thinking about the proper use of layers of abstraction and separation of concerns, Gang of Four design patterns or why an abstract class was used instead of an interface. Take a look at any mediocre app’s review distribution in the App Store. You will inevitably see an inverse bell curve. Lot’s of 4’s and 5’s and lots of (but hopefully not as many) 1’s and not much in the middle. This leads one to believe that even given the subjective nature of a 5 star scale, users still look at things in terms of either “this app works for me” or “this one doesn’t”. It’s all still 1’s and 0’s.
Even as a contributor to many open source projects myself, I’ll be the first to admit that have never sat down and cracked open the Spring Framework to truly appreciate the work that has been poured into it. Yet, when I’m in backend mode, I’m working with Spring nearly every single day.
The moniker Software Craftsman helps to convey the fact that I put my heart and soul into every line of code that I or a member of my team write. An API contract isn’t just well designed or not. Some are better designed than others. Some are better documented than others. Despite the fact that the end result of our work is literally just a bunch of 1’s and 0’s, computer science is not an exact science at all. Anyone who has ever taken 200 lines of Java code and reduced it to less than 50 lines of reactive Kotlin, anyone who has ever hit that Utopia of 100% unit test coverage in a class, or anyone who can actually read that 2-line Perl implementation of the RSA algorithm understands this simple truth. Software development is an art form. I am a Software Craftsman.

His long do you think it will take for Google to come up with a true replacement for Java. A replacement, not an alternative like Kotlin, but a complete "go f**k yourself, Larry" replacement that anyone can port their Java app over to. On January 1, if you are a for profit, Larry had said if you want to update to the next version and use Java SE to code with, you need a support license. It's a brill move, because Java is everywhere, and at least for a little while, it will generate a respectable profit for Oracle. But I'm sure Google is working on something to stick it to Larry. Wonder if EU competition chief Vestager will threaten am investigation. This should be fun to watch.19

Just learned how to write a for loop in kotlin and I now want to burn Java to the ground. When I first learned for loops in Java my brain almost imploded.2

Guys, What is the future of Kotlin? Is it a dead end? I mean many companies still use Java and google also released Dart for cross platform app development in previous years. Is there any point in learning Kotlin?18
-
Hi, so I want to get into Android App development.
I know the basics of Java and I have already written some simple apps with Java.
However I would like to get more serious with it and now I wonder if I should directly start writing apps in Kotlin or if I should write them in Java.8 -
Instructor: "and now here we can write this while loop in ph- oh wait. Let me just show you a cool trick. I am gonna close this php tag with ?> , open an html tag , then again open this php tag , add this line, close it, then again close html tag, then again open php, and then close it. pretty crazy huh? You see, now we can have our cool bootstrap displaying this output beautifully"
Me : FUCK YOU MAN :|
for reference, this was the final output :
============================
<?php
while($row = mysqli_fetch_assoc($result_successful)){
?>
<pre> <?php print_r($row); ?> </pre>
<?php
}

I am a newbie in web dev who comes from a very nice java/kotlin world. is this a common site in web dev, mixing of all the html/php/some 1000 more laguages and frameworks to make 1 working product? coz it sucks.11 -
What do you think about my language choice set for the future (knowing I want to work as a software and app developer) ? Anything to add / remove ?
- C++: Fast and well-documented, so I think it's a standard even in the next decades to come
- Java: Although I think that this language will more likely die in the next decade, I'll maybe keep this language because some dinosaurs enterprises still rely on it. Ah and mainly because it's still widely used in Android apps programming. For now.
Talking about Android, does learning Kotlin worth it ?
- Python: Will mainly use it for automation and prototyping, but nothing more, as it seems not to be widely use in the software development field (or it is ?). I'll also keep it for hobbies, however.
- Rust: This language seems to be a rising star in the industry since it is very clean, classic, as fast as C / C++ while introducing more safety. However I'll wait a bit for this one since it requires more complicated and abstract knowledge I do not have yet.
- Javascript (or more particularly JSX): Hurts to say I'll keep it, even more than Java. I'd let it in the web development hell I won't step in if it was not used in webapps / cross-platform mobile applications. And since this kind of stuff looks trendy, I don't think I can avoid it. Plus, I liked working with React Native. Sorry.
- C#: Seems to be a must when working on Windows software interfaces, so guess I'll have to learn this one. Will do so gladly, it looks better than Java17 -
Question here - what do you guys think of Kotlin?
Do you also think it'll be sufficient to learn Kotlin and not java to programm for Android?
I just began the transition, it's fun playing around with it, but a friend of mine wants to learn Kotlin to learn Android programming (and not java, he only has java basics).
What's your opinion on all this?12 -
our new cto is advocating to start migrating our existing and any upcoming new features from php to kotlin.
I tried looking into kotlin but it just doesnt feel nice to me. call me an idiot for actually enjoying php or java but i really dont feel like using something other than them.
i don't want to write Kotlin or Go or anything other than php or java which I already feel extremely comfortable with.
Maybe id love writing Rust even tho im new to it but anyway...i got too used to my comfort zone... and very few *new* things tend to interest me anymore.
whats wrong with me9 -
Was recently asked if our team wanted to change from Java to Kotlin so I looked over the feature lists but don't see much that's impressive.
One argument was less boilerplate code but I think they're are libraries like Lomboq that can write that stuff for you.
The other was smart type casting and type inference and to that I'm like this sounds like giving monkeys a hammer.
Our JS codebase looks like shit... And our Java app just crashed in prod.
Getting a ton of text messages this morning and thankfully I'm on vacation still...
The error is not caused by NPE... but how some or logic spammed the db..
A new language isn't going to fix this.... And a team that writes this sort of shit logic clearly shows they are incapable of learning a new one probably...
They are already script kiddies... Don't need them to become babies...6 -
I got exams coming up but all I want to do I get my hands dirty with kotlin, python and learn the java design patterns 😭1

Here's the description of java.lang.NoSuchMethodError from https://developer.android.com/refer...
"...Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed."
Now, what are the chances of your app crashing on customer's device because of this, when calling an OS function, VibrationEffect.createPredefined(VibrationEffect.EFFECT_DOUBLE_CLICK)? In my case, it's 50/50. Lesson learned Google. try{}catch{} around every line of code from now on to deal with your stupidity.4 -
Why is it that the tech Youtubers of this world (and tech reviewers in general) tend to completely skip development as a use case, and instead (if they do ever move off gaming) focus on things like Rendering & Modelling / CAD work? I'm sure there's *way* more devs in the world than CAD guys, surely?!
And if they *do* give it the light of day, it's always a quick benchmark based on "Firefox compile time", "Linux kernel compile time" or similar. Dude, it's 2020. Much as some would like to believe otherwise, most guys stopped compiling swathes of heavy C & C++ as part of their normal workflow over a decade ago.
Real-world tests I want to know about are things like docker performance, common IDE startup performance, compile performance of different sized applications on a bunch of langs like Kotlin, C#, Java, Clojure - or node.js performance, Tensorflow performance on NVidia's vs AMDs latest GPUs, etc. I care about how many IntelliJ instances & VMs I can have open way more than how many Chrome tabs I can forget to close.
But noooo - forget that, here's how fast Blender can render a BMW! 😬5 -
C# devs go crazy once they found out that kotlin has got extension methods
and some other c#-like features
Just use Scala.
There's a reason books with titles like 'Scala for Java/C# refugees' exist3 -
Is kotlin worth coding in? Or is plain Java better? There are many people here coding in kotlin what made you change to kotlin from Java or from anything else? Is there a specific reason? Speed? Stability? Anything? Is it worth using it instead of Java?9

Why the hell do languages like Kotlin (Java) and C# handle dates and datetimes so needlessly complicated?
There are multiple types with different implementations and concepts like local time or time zones represented by those types. Some of them have capabilities like serialization, some of them don’t.
Parsing and encoding is tied to the types.
Why? Take Swift as an example:
It has one single Date type (including time) which represents a point in time independent of any calendar, time zone, encoding or format.
There is a DateFormatter to parse from APIs from iso or timestamps or whatever and to format to UI as a string in any language (localization), for any region, in any format.
If you just want a container for the date time components themselves (which the concept of local date time seems to be in those languages), you can use the DateComponents type. If you are interested in dates from the perspective of a calendar, there is a Calendar type.
Everything makes sense and the different concepts are decoupled from each other as they should be.
Damn! My memory about C# is a bit hazy but Kotlin, I’m disappointed in you! Date handling is a horrible mess!
Ok, I guess I can blame it on Java and JVM.6 -
Was recently in a motorcycle accident and haven't been cleared to go back to work yet so I'm trying to build my first Android app.
I don't know Java, XML, kotlin, Android studio, or what the fuck a Gradle is; but I figured I'd take my app idea and download Android studio then try winging everything from there.
Needless to say, I'm having a damn hard time lol. I have been watching firebase tutorials on YouTube to try and figure out how to add authentication to my app. I kinda got it working in the AVD. But my personal Google account has 2FA enabled so I can't seem to get the app to sign me out, or sign me back in. (I was able to authenticate once successfully.)
I have no idea if having 2FA enabled is even the problem. I tried turning on debugging and can't seem to figure out how to actually get the app to debug or get a debug console open.
I seriously feel like the world's biggest n00b right now. Going to go YouTube/Google how to get the debugging working. Then I'm off for a round of learning how to read a debug report!
Hahahaha... Kill me now -_-'2 -
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.

2) C -- I burn way too much calories talking, let's do some sign language. Now see over there... 👉
3) Python -- Missing semi-colon? Old method. Just add an extra space and watch the world burn.
4) C++ -- My ancestors made a lot of mistakes, let's fix it with more mistakes.
5) Go -- Meh. I can't believe Google can be this lazy with names.
6) Dart -- I'm the new famous.
7) PHP -- To hide your secrets. Call us on 0700 error_reporting(0)
8) JavaScript -- Asynchronous my ass!
9) Lua -- Beginners love us because arrays start at 1
10) Kotlin -- You heard right. Java is stupid!
11) Swift -- Ahhh... I'm tasty, I'm gonna die, someone please give me some memory.
12) COBOL -- I give jobs to the unemployed.
13) Rust -- I'm good at garbage collection, hence my name.
14) C# -- I am cross-platform because I see sharp.

I decided I am going to get full into Minecraft modding. It will be an opportunity to learn Java and Kotlin. I want to explore some game ideas in a well defined sandbox.
Some things I want to explore.
1. AI that helps you build and survive. This fascinates me and seems like it could be a good challenge. I like the idea of learning how to separate structures into chunks. I think I will learn a bit about tree data structures here. Maybe learn something about BSP trees (if applicable).
2. The idea of an RPG quest system tacked onto a sandbox. I want to spawn structures and create non-repetitive story lines. Minecraft can be really desolate if you are not playing on a server. Worlds tend to be empty and devoid of story.
3. Maybe try a hand at terrain gen. This could be fun to explore entropy math. It is fun to draw things with math.
I am sure I will come up with other fun things to explore here.9 -

I just got a legacy java system and im starting to see why kotlin should be implemented, so fucking imbeciles cant use null as a database path

I'm starting to rank languages based on how easy is to create and work with multi dimensional arrays.
Converting a class that makes lot of DB connections from Java to kotlin made me realise that. Huge turnoff 😞3 -
I can't shift to kotlin because my company is fucking around on being on Java 7 (with retrolamdas *wink*), where it takes 10 minutes for a gradle build.1

I take a look on Dart, which used by Flutter, a "React Native inspired" framework.
Very similar to Typescript and Java, so whatever you write, probably gonna work.
But I feel lack confidence on any language Google promoted. Eg kotlin and Go
🤦♂️
Google hired too many PhDs who have nothing to do, so they spend 1 day per week draw some doodles...
Hope this is not another weekend warrior project.🙄9 -
Hey guys. I am in a situation where I need to decide wether to take on a new project or not. And if not, how to turn down that client so that I would not burn any bridges. So I need your opinions on this matter in order to make the final decision.
To make things clear heres some background info. 10 months ago I quitted my fulltime position in another EU country and went back to my own home country. 10 months forward till today and I have my own ltd company which currently has 5 projects. Its doing pretty well money wise. All projects combined, I already earn more then I ever did and I need to work max 10 hours a week since all projects are remote projects so I dont waste time on useless meetings and etc. However I dont feel fulfilled or challenged anymore because surprise surprise doing well paid projects doesnt guarante your sense of fulfillment.
So I noticed that I have lots of spare time which I spend diving into rabbitholes with hobby projects. I decided that its time to scale my company and take on more projects and maybe even hire more people.
So I started searching for other projects I could work on (prefferibly remote projects or flexible ones where I could come in 2-3 days a week in office and work remotely rest of the week). Reason being that I am already out of sync with fulltime position lifestyle and I am totally result oriented, not punch in my hours and go home oriented.
For exampleIf i get my weekly tasks I prefer to do them in 1-2 days (even if it requires doing double shifts which rarely but happens) but then I want to have rest of the week off. Thats how my brain works and thats how Im wired. I cant stand fulltime positions especially in enterprise bigger companies where I come in and do maybe 2 hours of actual work everyday because of all useless meetings and blockers from backend/etc. Its soul crushing to me.
So I posted linkedin ads and started searching for new clients/projects. One month ago I went to an interview for an android project in a startup.
The project looked interesting enough. Main task was to rewrite their android app from java to kotlin. Apparently their current current app was built by a backend developer who wants to focus solely on backend.
So during the interview they showed me their app which was quite simple frontend wise but not so simple backend wise from what I was able to figure out.
Their project lead (also a backed guy) asked me my estimation of price and completion of task. I told them maybe 2-3 months to do everything properly.
Project lead was basically shocked because all other candidates told him they can rewrite the app from java to kotlin in 2-3 weeks. I told him that everything is possible but his app quality will suffer and for a better estimation he would we would need to sign an NDA so I could evaluate the costs. So we ended the interview.
After that we kept in touch for one month (it took them one month to google a generic NDA and sign it digitally with me).
So heres the redflags I noticed:
1. They dont respect my time. Wasted 1 month of my time and after signing NDA gave me 2days to estimate their project and go to a meeting and give them detailed info about what I can offer. I thats not a brain rape then I dont know what it is
2. They are changing initial conditions we talked about. We agreed on rewriting the codebase and be done with it. Now they prefer a fulltime worker who would be responsible for android app as his own product. So basically project lead was not able to find a fulltime dev so now hes trying to convert me (a company owner) to his fulltime worker.
3. Lack of respect. During the interview he started speaking in his own native language to me with some expression (he seemed pissed off at that moment when he switched languages).
4. Bad culture fit. As I said Im used to relaxed clients and projects where I dont need to be chained to a desk a monitored and be micromanaged. I mean lets sign a contract give me access to your codebase and tell me what to do, I will produce results and lets be done with it.
5. Project lead is a backend guy who doesnt understand how complicated android apps can be. No architecture and no unit tests are in his frontend app. He doesnt care about writing proper app since he ships it in his own device so he doesnt need to worry about supporting custom devices or different api levels of android and etc. But not having any architecture? Cmon.
So basically I am confused. Project lead needs a fulltime dev but hes in contact with me in hopes that I would sign a fulltime contract. But how I can work fulltime if all what I can see are redflags?
Basicaly I thinkthis was a misundersanding. Im searching for fulltime remote projects and hes offering fulltime inhouse projects. Project lead never outsourced so hes confused as well.
As you can see decision is already basically made to turn him down, I just need to know how to tell him to fck off in the most polite manner and thats it.6 -

I am thinking about picking up a functional language. Currently I use Kotlin (and I fucking love that language) but I have to admit that it's support for functional programming is limited.
But I think their lies a certain beauty in fp and I want to do some project with it.
The 2 main problems are:
1. I have no experience in functional programming. I have no clue how to structure my program (potantialy without oop) and write clean testable code.
2. I don't know what language to use. Scala seems great since it has good IDE support and I like the Java ecosystem and Haskell seems to have more beauty but is missing that IDE support and it is very unfamilar for me.
So what do you guys think I should pick up? And how do I learn to write good software with it?17 -
Fucking shitty ass educational products fucking really suck. Literally, one of the schools we work for has a piece of software called Blackboard that seems great and all until you realize that its written in Java and you have students and teachers who barely know how to turn on a computer using this thing! I'm not even kidding when I say that one student can bring the entire thing to its knees just by causing it to throw a NullPointerException and to make matters worse teachers are allowed to customize their "classrooms" which as part of that they are allowed to add plugins. Some of which also cause fucking headaches and NullPointerExceptions. The least these fuckers could have done was switched their code to Kotlin or something that could actually handle improper types without crashing the whole damn thing.6

Where can I find a well paid junior Android Kotlin position?
I've been working in Switzerland for nearly 3 years now. I earned 72,000 (CHF) the first year, 78,000 the second year and now I've reached 86,400 at my current job. I quit this job and with the new job I'll be earning 96,000 after a 3 months trial period in which I'll earn the same as I earn now. I see a lot of Java jobs with Spring Boot and Angular but I'd really like to work with Android and Kotlin, I applied to Element.io and got rejected so I think I might need to apply as a junior Kotlin developer even though I have quite some experience.
I'm not sure where I could look for Kotlin jobs and if it's possible to not deviate too far from my current salary, I'm not sure which country and I'm not sure which platform I could use.
I've tried some stuff on LinkedIn and Indeed and others and I've tried in Switzerland, Israel and the US since I speak English and Hebrew natively and German fluently.
P.s. I know that you're all going to say that the expenses in Switzerland are higher, but I'm very frugal and this doesn't apply to me that much. I still earn a lot more than I would earn in Germany for example and I really don't want to earn 10,000 less...

Learning Java for the new position I start in a lil over a week. Biggest struggle migrating from PHP is wrapping strings in quotes ONLY...no apostrophes lol. I guess I formed a bad habit. Also slightly frustrating is that you can't overload a method and set defaults. I guess you get that with Kotlin but this company is going to switch away from Java to GoLang and React, so I guess I won't really get to enjoy Kotlin.

Hello everyone.
I recently started android app development and i wanted to ask if you code entirely in java/kotlin or use xml+java/kotlin ?
I feel like to get better i should code entirely in java/kotlin. Am i wrong?3 -
Looks like Android studio's artificial java to kotlin converter learned faster to write better kotlin than my shitty brain :/
People from java background, where did you learned to write efficient kotlin code and how?
Where to learn how to write that famous "kotlin's super precise and small , ugly ass anonymous looking code full of keywords , that only work when arranged in a particular pattern and defies my all previous knowledge of oop , java and good practices " code?
I really wish to learn, since android and google seems to be heading towards this beautiful new shit1 -
For Java and Kotlin I use IntelliJ, for like config files and crap VsCode.

Although iv only been developing in android for around 7 months yet I fail to see the appeal of Kotlin.
It has no real advantage over Java. In my opinion its fucking lazy code. It might look pretty but that's about it. So I don't see why employers are opening their arseholes for people with Kotlin experience.
Im pretty sure they are doing it because its "the next big thing". If you can write solid Java I dont know what the big deal is.. Maybe someone can shed some light on this..
Android studio can convert Java to Kotlin with one click. So No Mr employer I do not see your reason why you employed someone over me because he has Kotlin experience. Its fucked!! So that project I handed you... the one where I had pride in my ability to apply solid Java... Yes remember fucking Java everyone?!... well it works exactly the fucking same and in my opinion is much more verified and readable. SOOOO FUCK YOUUUU MR EMPLOYER!!!!! Go FuckYourStupidLittleKotlinBumChumsRightInTheirShitRiddenFuckHoles!!!!!!
Rant over...3 -
The most fun I ever had coding was when I first discovered Kotlin. After using java for most of the time I've been programming, Kotlin felt like a godsend. When working on converting one of my old projects, I was amazed by the reduced verbosity and just how clean it felt.
To any devs that still use java at all, do yourself a favour and take a look at Kotlin (kotlinlang.org)1 -
I handle multiple projects at a time... Sometimes I feel stupid to mess up the basic syntax of Kotlin and Java.
So I made a stupid mistake in my code like this. I wrote this in Java file
" val something : String = "value"; " (which this is a Kotlin syntax, without knowing that I am coding in a Java file not Kotlin!
Oh stupid me~3 -
I'm thinking about what language to dive into next.
I already have a pretty good knowledge of Go and mediocre knowledge of C and Java.
So far I thought about...
1. CPP, as I need it for school and it runs on literally anything.
2. Rust, as is seems to spread and the combination of low-level, memory-safety and abstraction seems pretty appealing to me.
3. Kotlin, specifically kotlin-native, is it combines java-like high-level programming with native speed.
4. Nim, as it combines high-level techniques with c-like freedom.
What do you people recommended, or something completely else?6 -
If I don't know Java and no plan to learning it how should i learn kotlin?
No experience with c or c++ either. No programming experience at all. Because HTML and CSS aren't programming so yeh. plan to learn JavaScript next month after my fucking exam.6 -
Q: Has anyone heard anything about Google leaving Kotlin and Java behind to use C# for Android development?
I was talking to someone who told me this yesterday. Of course I dnt believe it, nor can I find anything on that BS he was feeding me.
That whole-ass 1 hour convo was BS from start to finish.
There was more crap said, but I’ll spear you all the details. I just need to know if this is even remotely true. I’m sure it’s not, but he’s convinced it is. 🙄13 -
I'll put it this way. Svelte is like Kotlin. It's modern, elegant and a pleasure to work with.
React is like Java. Old, bloated and a pain to work with.
Svelte makes React look like it was built by masochists.
I don't work on frontend often, mostly because I despise the frameworks.
Svelte is a breath of fresh air.
I just want to ship a product quickly and it doesn't get in the way.2 -
I recently performed a huge refactoring effort on a Java project converting both the persistence and utility layers to Kotlin. Gotta say, I think I'm starting to fall in love with programming again!

"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.3 -
Oh now that I'm remembering, this is how I learned PHP. It's not my specialty, but I'm writing a small plugin for WordPress.
I was in a dinner with my partner's family. One of their parent's siblings manages the IT in their company, and we had this conversation:
family member: So what language do you know?
Me: A bit of C and C++, and I did a project last year in Java/Kotlin. But my current project uses mostly Python.
Family Member: Oh Python? But Python is a very easy language, even I could learn pretty quickly. That's why we don't use it in my company. We use PHP.
Challenge accepted!
Within a week I was able to learn PHP and some basic templating library, and replicated most their company's website into a new server.5 -
Holy shit, Kotlin does not have package-private?! I thought Kotlin was just a bad mix of JS syntax and Java... but not supporting an essential feature of the VM is on a whole another level of bad.8

Why are devs at google making it hard for android developers? They release libraries so frequently and completely overhaul everything. It was fine till a limit. Now again they are releasing jetpack compose which is a completely new thing. I don't have problem learning new things but the rate at which they release new stuff is far swift than other frameworks. For example they release a new dependency injection hilt while recruiters still look for dagger 2. Android is just getting overwhelming. What are your thoughts?4
-
Why do developers out there think java is a write off just because of kotlin's existence? Java isn't going anywhere fam, you know how large the community of Java programmers is? You'll hardly find stackoverflow answers written in kotlin. Kotlin is the official language just as c# is for Microsoft but that doesn't stop anyone from writing windows software with java. Stop scaring potential java programmers with "ANDroId iS rOotiNG For kotlIN" for fucks sake.3

Asking Android developers: I want to learn how to make Android apps. I know a little bit of Java and thus kotlin too. Which resources do you guys recommend?5

everytime i try to learn kotlin, i can only think WTF is happening, why should it be happening?
after wasting last 4 hours, i came to this conclusion table regarding kotlin var and val notation.
And now my fucking compiler is saying that i can rather write :
val x:Int
and initialize it later, when i thought val is immutable and must be initialized at the beginning only(like public static final int x =5)
Who the fuck are those people that like this stupid language? why would you say some variable as immutable(meaning which can be changed 0 Times "ONCE" ASSIGNED A VALUE ) and when i can create a program with a variable that never got ASSIGNED A VALUE EVEN ONCE??10 -
I've been learning android app development using kotlin/java for about 4 months, and i think i'm pretty good with kotlin/java, i've learned a lot of things related to android development, i've cloned netflix,spotify and made streaming apps with firebase as the backend, and I think I understand using firebase quite well because firebase itself is not difficult to use. Is it for my current skills that I deserve to work as a freelancer or do I still have to improve my skills?if it yes,give me an example of what kind of application I should do to improve my skills again!,I've read the android studio docs what to know and I've studied everything even though I sometimes forget how to make this/make that but I understand the logic quite well ok, please help7

Why oh why, why does my project not work... 2 hours later, "Oh Damn, I forgot a semicolon. That's it, I'm switching to Kotlin."1

I feel that it's better to develop in Kotlin, for android, as a beginner, given the recent announcement.
Any other suggestions?12 -
makes me cry whenever i see a fkig tutorial use the fkig kotlin instead of my fkig java gddamn whats a nigga gotta do to get a fresh tutorial with java7

Everything is shit and I have to work drive thru till 11.15pm.
Everything appears to require js at one point or another (though kotlin requires groovy which, in the intellij IDE, the template it COMES with is fucking broken from the start)
c# could work (and microsoft shop jobs are plentiful) but fucking VS code is a headache and microsoft seems intent on locking everyone into VS and making everything they touch turn to shit, like the king midas of diarrhea (thanks MS, monodevelop is source only on windows). Also c# for android (xamarin) requires apache cordova to do anything, which means...TADA, FUCKING JAVASCRIPT and all the other shit it brings with it.
Java seems like an option, lots of jobs available, but I need netbeans for desktop (javafx) and Android Studio
separately in order to do anything. And Android Studio now uses, of all things...FUCKING GROOVY.
*cocks gunfinger and points in mouth*
why must every fucking thing be it's own DSL and make everything about the fucking ceremony of configuration over
fucking convention?
Haven't any of these fucking cocksuckers heard of MAKE? Or do they just masturbate over how intelligent and smart they are for having reinvented the god damn WHEEL?
I'll see you at the drive through. Will that be all for today?9 -
Not sure if this is against the rules (can’t find it) but taking the risk to post this here.
I’m android(kotlin/java) and Golang Developer looking for a remote job in any company. I’m really bored and tired of not doing anything daily.
Here’s my resume on google drive: https://drive.google.com/file/d/...4 -
Worked as android dev for 2.5 year and then worked as java gameserver dev for 2 years.
Now I wanna go back to android dev so I spent the last month grinding kotlin/android basics and already have 2 interviews lined up this week. Applying for junior dev role because of my gap and because my confidence in my android ability currently is really low. Having ADD doesnt help because I suck in memorizing implementations, syntax and I suck at live coding under pressure.
Fuck it I will set their expectations low, will get lower salary and hopefully will impress the hell out of them during first few months. Wel see what happens...
Any tips/advices?4 -
Tips for learning 2 languages at once? I'm learning Java in school, and I'd like to learn Kotlin as well. I know they're similar, so my main concern is just mismatching syntax.4

Plans:
Learn Rust and C++
Trying out the new K2 Compiler and probably ditching java for kotlin because kotlin is java

I'm building an Android App and need to implement multi option selection using images. Tried google searching "android libraries for multi-option selection using images as option items just like Medium.com" but i keep getting links for image picker libraries instead.
Have you ever come across any? cus i'm not ready to implement that from scratch. Thankee2 -
Hey I am just curious, do you think is there any good reason to stick to Java now that Google officially supports kotlin?
Thanks1 -
LOL XCode....I think they meant "X"tra useless, resembling such as a bag of dicks without handles!!!!
Also, being fucking buried because there's aren't any devs anywhere to be found near me makes me extra cranky!
Ive been hammering away at this Flutter, Java, Swift, Python, and Google maps for just about 36 hours on 3.5 hrs sleep. I just can't stop, I fuckin love this shit!!!
Considering the fact that I'm self taught and just started writing code for real about 7 months ago, I'd say I'm handling this alright for now. Every bit of tech is getting shot out of a cannon at this one- maps, real time tracking, state level auth/Id verification, custom components like ID scans/native desktop applications on custom linux machines, body cams, SIP trunking... all in 3 apps which are 100% multi-platform and scaled up to high end enterprise levels and being groomed for national release. I'm writing the code and doing the tech for ALL of it- even down to custom painted barcode scanners, a wallet system built from scratch, GPS integration, location/geofence based document querying... holy fuck guys I'm gonna fuckin die haha!!!
I went from barely getting websites made in late summer to this very moment, where I am pumping shit out in Flutter, Dart, Python, CPP, Js, Swift, Java, Kotlin, Obj-C, SQL/noSQL, and who knows what else.
I don't even know what the hell I just said haha I hope everyone has a great day! -
You look everywhere to be puzzled of what went wrong and realise that you missed a semi colon assuming that language to be semi colon independent.

Hi devRant,
I'm starting a little side project (a web app for finding/booking musicians) and have to decide which language to use for the backend. I have broad experience with Java and C#, but it would also be nice to learn something new (Kotlin? Go? Rust?)
Additionally, what's your recommendation for databases? (SQL vs. NoSQL vs. ...)
For the frontend, I'd like to use typescript, webpack and Vue.js.
Any thoughts? ;)8 -
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!4

So is it feasible to develop iOS swift apps also using vscode? Is it smoother than Xcode?
What about android apps...android Studio is so slow, what all will I miss if I use vscode for Java/kotlin apps instead?4 -
Hello!. I have a little tech app idea I'll love to startup. I made an educated guess that my target users are mostly on the android platform. At least 70-80%.Now I don't have funds to get a development team and I want to keep the expenses to the barest minimum. I have a little tech background. I have, used html, css, c# in the past. I always hated Java in school. But it seems I have to embrace it or Kotlin for the development of the app. I want to be able to build at least the MVP and try to gain traction. I am also thinking about cross platform options to cater for both Android and the few iOS users we may have. React Native and Flutter comes to mind. I also think I can get someone highly technical than myself as a co-founder to help. I will appreciate it if you can drop your 2 cents.15

I'm learning Kotlin while trying out Android Things and that sparked my interest in learning more about Java platform again. I tripped upon the news that Oracle had change their commercial plans for the platform by going with the rolling release model and limiting LTS releases for paying customers.
Java SE 8 was one of those former LTS releases that was on my computer, leaving me vulnerable, despite that version still being the most compatible with many applications, and that's been on my computer well passed the date they cut off public support. And I'm, like, "WTF!?"
Luckily this is when open source shines at it's brightest. Both the home brew and corporations, such as Amazon and IBM, alike - mostly the latter - both agreed to create their own LTS releases using the OpenJDK code and all disturbing to the public FOR FREE with no strings attached and the sources opened. I'm sure Richard Stallman is smiling with glee.
It isn't a total finger towards Oracle. Java SE is based on OpenJDK with no difference between the two anymore aside from loss of LTS support from the public - that's it. So Oracle still benefits despite the retaliation. Probably?
Did Oracle learn nothing from OpenOffice? If the point was to get users to pay for security then they've failed in the long run because Java is open source. People have used that fact to create their own free distributions that bypass their paywall, making the need to go through Oracle pointless. And I'm glad. Open source aside, security is a big issue these days and the last thing people need is yet another thing to subscribe too.1 -

In Kotlin or Java, I have a list of items that have an ID property. This list is generated based on another list. Now I get a List of mentioned list items and I want to select all items in the parent list, selecting by ID equality.
Is there a more elegant way than just iterating the parent lost for each derived item? Thank you :)5 -
I'm building an Android app from ground up targeting to have functionalities added without much effort in succeeding phases.
What I'm pissed about mobile development at the moment though, is its lack of structured code base that is easy to follow. Unlike web where codes are modularized and well placed, in mobile, I kept going back and fort in different modules to see how they are used in all places in the project which made it tedious as time goes.
So I kept a notepad keep track of detailed flow. However, once I go back at the notes to place them on top of your head, the almost spaghetti-like structure just becomes very hard to track. For me it doesn't follow a pattern and that developers are free to do what ever they wish so as long as it can run in the device or emulator.
For instance, implementing concurrency as well as dependency management and a Clean architecture is such a pain. I hope i can relate to someone here.
If only there is a standardized way of structuring codes in android in Java or Kotlin (haven't tried this), there would be hope for me. So if anyone can provide a good, readable, reliable android project that I can start building my project on top of, your help will be greatly appreciated! Thanks for reading. -
Wait someone said Java is going downhill and new projects aren't really made in Java anymore outside of Android? The fuck I'm just learning Java. Granted I really am learning it because I want to make stuff for Android but again wtf? Will this become its only use at some point til Kotlin takes over?3

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.5 -
I have a little ask for you guys, If you need to start a Java project, Will you use kotlin or Just Java? I'm a little confused with this choice, so i need more visions19

I am using python scripts for mathematical computations and deep learning wheres spring to build the server and now want to handle the scripts from spring guess what scripts were in python 3.6 and fucking jython does not support it.. so tried finding the different libs like jpy , jpe and analysisRPC.. Everything seems just bullshit .
Finally using Kafka to have my interprocess communication.. -
I really cannot see why there still isn't an API in Java where I can get an hashing algorithm without having to catch a checked exception.
Granted, Bouncy castle is a top library. But of you just have a small application with a single method wanting to hash a few values... It's so nuts and unnecessary.
So what do you do in the catch block? Either throw a checked exception (because without that hash your app won't work), or calculate a replacement. But if it were that easy, I wouldn't have needed a hash on the first place.
I really wonder what the java developers had in mind.
Same with IO exception. I'm beginning to like python more and more.
And, of course, kotlin.5 -

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.13 -
Is kotlin viable? I feel like I could just suffice with using either Java or JavaScript depending on the situation at hand... :/1

Random thoughts...
Just implemented policy-based authorization in dotnet core, long story short to lock an endpoint to a certain policy I just add: [Authorization(Policy = "NAME")]

I'm trying to understand Dependency Injection.
can I say dependency injection represent a class that is dependent of another class?11 -
i am feeling angry and frustrated. not sure if it's a person ,or codebase or this bloody job. i have been into the company for 8 months and i feel like someone taking a lot of load while not getting enough team support to do it or any appreciation if i do it right.
i am not a senior by designation, but i do think my manager and my seniors have got their work easy when they see my work . like for eg, if on first release, they told me that i have to update unit tests and documentation, then on every subsequent release i did them by default and mentioning that with a small tick .
but they sure as hell don't make my work easy for me. their codebase is shitty and they don't give me KT, rather expect me to read everything on my own, understand on my own and then do everything on my own, then raise a pr , then merge that pr (once reviewed) , then create a release, then update the docs and finally publish the release and send the notification to the team
well fine, as a beginner dev, i think that's a good exercise, but if not in the coding step, their intervention would be needed in other steps like reviewing merging and releasing. but for those steps they again cause unnecessary delay. my senior is so shitty guy, he will just reply to any of my message after 2-3 hours
and his pr review process is also frustrating. he will keep me on call while reviewing each and every file of my pr and then suggest changes. that's good i guess, but why tf do you need to suggest something every fucking time? if i am doing such a shitty coding that you want me to redo some approach that i thought was correct , why don't you intervene beforehand? when i was messaging you for advice and when you ignored me for 3 hours? another eg : check my comment on root's rant https://devrant.com/rants/5845126/ (am talking about my tl there but he's also similar)
the tasks they give are also very frustrating. i am an android dev by profession, my previous company was a b2c edtech app that used kotlin, java11, a proper hierarchy and other latest Android advancements.
this company's main Android product is a java sdk that other android apps uses. the java code is verbose , repetitive and with a messed up architecture. for one api, the client is able to attach a listener to some service that is 4 layers down the hierarchy , while got other api, the client provides a listener which is kept as a weak reference while internal listeners come back with the values and update this weak reference . neither my team lead nor my seniors have been able to answer about logic for seperation among various files/classes/internal classes and unnecessary division of code makes me puke.
so by now you might have an idea of my situation: ugly codebase, unavailable/ignorant codeowners (my sr and TL) and tight deadlines.
but i haven't told you about the tasks, coz they get even more shittier
- in addition to adding features/ maintaining this horrible codebase , i would sometimes get task to fix queries by client . note that we have tons of customer representatives that would easily get those stupid queries resolced if they did their job correctly
- we also have hybrid and 3rd party sdks like react, flutter etc in total 7 hybrid sdks which uses this Android library as a dependency and have a wrapper written on its public facing apis in an equally horrible code style. that i have to maintain. i did not got much time/kt to learn these techs, but once my sr. half heartedly explained the code and now every thing about those awful sdls is my responsibility. thank god they don't give me the ios and web SDK too
- the worst is the shitty user side docs. I don't know what shit is going there, but we got like 4 people in the docs team and they are supposed to maintain the documentation of sdk, client side. however they have rasied 20 tickets about 20 pages for me to add more stuff there. like what are you guys supposed to do? we create the changelog, release notes , comments in pr , comments in codebase , test cases, test scenarios, fucking working sample apps and their code bases... then why tf are we supposed to do the documentation on an html based website too?? can't you just have a basic knowledge of running the sample, reading the docs and understand what is going around? do i need to be a master of english too in addition to being a frustrated coder?
just.... fml -

I've just joined a new company out of despair after several month out of jobs without being able to even get interviews.
I've been warned about the code being a bit behind with modern Android stack, they needed to migrate from rx to coroutine and compose is not a priority at the moment.
Fine with it, I like handling and planning migration, that's a nice challenge.
But if only that were the only problems !! Far from it, the code is a formidable mess, I've never seen so much amateurism... Most of it was written from the previous Lead Dev who stayed there for years and touched everything with their very bad practices.
I don't even know where to start honestly...
While the code is in Kotlin, it stink Java. Nothing wrong about Java, but if you code in kotlin, you need to understand what kotlin try to achieve. And that's not the case here. There is freaking nullable everywhere, for no reason at all, the data classes contains lot of var in their constructors, equals are override to compare only one or 2 params and no hashcode override with it.
Sealed class, what for ?! Let me just write a List<Pair<Enum, Any>> and cast your any depending on the enum !
Oh and you know what, let's cast everywhere, no check, and for once no null safe, there is enough nullable in the code !
What about the reactive part ? well let's recreate a kind of broken eventbus with rx ! Cause why not ?!
The viewmodel observable don't contain data, they just contain enum for the progress of the states we're checking.
In the viewmodel function we update that enum states and emit it to be observed and make the data available as a var for the view to pick it up when needed.
But why put the business logic in the viewmodel, let's put in the views, and grab and check the variable contain in the viewmodel whenever it fits.
Testing the business logic ? uh let me just test my variable initialisation in the viewmodel instead.
The vm, the views, make about 2000 lines, the test over 3000, and not a single test really test the business logic in it ! I've made big refactoring we're all the tests stayed green, while the function are full of side effects ! WTF ?!
Oh and what about that migration from rx to coroutine ? well better not break the existing code and continue writting like rx, everything is cold flow ! We just need to store a boolean saying if we already did our call to the data layer then we decide to start our flow or not.
As for the RecyclerView, having too many viewHolder is just so annoying, let's put all our different views in one, and hide what we don't need.
Keystore has been push on the repo, but it's private no ? So who cares ?!
And wait i'm not done ! Some of the main brick of the apps depends on library that hasn't been updated for years, and you know what... yes they were hosted on Jcenter and it's only now that they decide to do something about it, we we're warned about the sunset of jcenter 2 years ago !!!!
So what about compose ? What do you want with compose ?! there is no design system in that app obviously, so don't even think about it !
And there... among all of that mess, I'm supposed to do code review... how the fuck do you do a code review when all the code that is around stink ?!
And there is so much more but by now I'm afraid you're thinking i'm just pissing on the old code like everyone... but damn I guarantee, that's the worst code I've ever seen, and i've work on more than 15 app from small to big on different contract with a lot of legacy code, but nothing that bad !1 -
Begin to hate Java, moving to kotlin soon . For android development at least with Jetpack compose. Java is deprecated in almost every API.

Ok so guys, I really love back-end, but sometimes I'd like to do a complete software to show off to friends in my free time, So question:
What programming language should I learn to make gui softwares?
I don’t want them to be pieces of art, just functional and with not too man " unintentional features".
I really love Python, but for gui heard it's meh, but may be wrong
I don't want web technologies
looking forward to learning C, but not necessarily for gui
could try c++ I guess
Don’t want .net (coz you know ms and their Java knockoff)
Ruby seems cool, but it seems to be annihilated by ruby on rails
Not Java but Kotlin seems really cool, could also go with scala, idk
Forgot the other things3 -
How does Kotlin compare to Java? Got experience / opinions worth sharing about them?
Always wanted to make some android apps as hobby but Java was grossing me out.4 -
I recently started learning Kotlin and while I like it a lot already I find it to be a really strange language at the same time. This is coming from someone mostly doing numeric stuff in Python (for my PhD) and Android development in Java (my personal side project, which I'm currently rewriting in Kotlin).
-
I am feeling a lot doubtful right now.
I am an average undergrad student who has been dedicating efforts in java/Android for most of my college life.
As of now i have decent command over java , launched 2 simple apps on playstore, worked as an android dev intern in 3 companies and make decent medium complexity apps. I will say i am 40-60% down the path of an expert native Android dev.
However apart from Android, am dumb as a stick. I know shit about ai,ml, web dev, js , react, hybrid stuff, and am not very good with competitive programming and system topics ( os, Algorithms, networking, etc)
So this closes a lot of doors for me. I can't apply to some top tier companies as they would either want expert competitive skills or expert Android dev skills.
I had bad experiences with startups which are usually willing take rejected students like me for the post of a droid dev... there is usually low packages , high pressure, and treatment like a slave
So i am very unsure what to do next. I have tried to learn web dev/ ai-ml-data sciences. They are not very interesting to me, but again, what is interest really :/
What should be my focus now?
A) I could be learning competitive and other interview related topics so that i could crack interviews of top companies , and later try to get a position of android developer there.
B) i could focus on become better in Android and start learning things that i don't know like rx, kotlin, etc. I could then hope to crack interview of medium sized app dev companies which would mainly focus on my android knowledge in their interviews
C) i could increase my skill set and learn web dev or ai/ml topics to increase my recruiter pool. It would be like option B, but i will have more medium sized companies willing to take me.
Currently i am in a shit storm. I am about to go into a mass recruiter company in which i have heard would be doing more or less data entry work2 -
I'm really worried about my future as a programmer. should i learn a new language? I already experienced in PHP and a little javascript and vuejs and recently i learned some golang for web and previously I do some java/kotlin for android app.
should i learn a new language such as python? node? or some new framework/library like react?
or i should stick with what i already know?5 -
I tried Kotlin for a week. And I literally gave up. Hey, fellow Kotlin devs, what fun do you get in writing this short f**king syntactically unmatched java code!5

also:
- Free time: lol, i was working at 1 am too
- Personal health: even lesser caring about, body fats and thick muscles at various places
====
it will be almost a year of me working for these guys in November and this has been an interesting year so far. the stats are:

also:
- Free time: a good amount of free time, like in addition to weekends and festivals, i take 2-4 leaves every month
- Personal health: improving a lot. loosing weight, gaining muscles, getting better stamina at running and other activities

So i am currently at a weird place. As from my stats, you can see that previously i was in a android heavy role in a company that put a lot of pressure, but i was able to become a better sellable dev through it.
My current role is also of an android dev here, but we maintain b2b products and i am sometimes asked to fix bugs in hybrid apps like unity, react native and cordova, so gained a few knowledge there too. and since i have a lot of free time in my hand, i explored a bit of web technologies too (apart from enjoying a relaxing life and focusing on personal health)
However my main concern is that am becoming a less sellable Dev. The lack of exposure/will to work on android tech has made me outdated from a framework that was once my stronghold. remember that i joined my first company purely because of my passion and knowledge of android os.
When i got offer from this company, i also had another, $5000/year lesser offer in hand. both of these offers were very generous , but i went with the greed and took the offer from this company despite knowing that they are looking for someone who will act as a developer-maintainer kind of person, while the other company giving lesser pay had a need of a pure android engineer.
So i am currently 24. should i keep on doing this relaxing but slowly killing job, or go into a painful, pressurizing but probably making me a better "android" engineer job ?2 -
So idk how to start this but ... ohm the short version would be that I'm in a little life crisis because idk where my career should go, i know the basics (maybe a bit more) about it security, i know how to setup a nodeJs server from scratch, i know frontend dev. , swift, kotlin, java, C , R and a lot of useless frameworks but nothing of this I'm really good in (what's ok because im in my 3 semester) i just don't know where i should go.
I seriously love every aspect of computer science but i also know it make no sense for my future not to focus on one suspect.
Now how can i find out with way i want to go ?1 -
Thought I'd give kotlin spring boot a shot. I assumed it would work out of the box like with java. It didn't. Apparently with jdk 17 I chose an incompatible version with the gradle version provided. Downgrade gradle. 'runApplication()' still marked with an error, which I cannot seem to solve. Answers from the internet are no solution.
But I can run the project ... but I cannot reach my dummy address, same with maven ... wtf, which part of rtfm did I miss? Wasn't kotlin supposed to be the better java?3 -
I would like to learn how to make a mobile app, but I do not know what to choose. Some say java, some say kotlin, then some react native and some flutter. I just wanted to ask for advice. And btw Laravel, Js, Jquery, Ajax and Cordova Apache are all I know so far.6

Any Kotlin or Java developer that knows how to delete files from SD-card in mobile devices. I have been battling this for over a week now3

update : we are at hr round baby!!!
part 1 : https://devrant.com/rants/5528056/...
part 2 (in comments) : https://devrant.com/rants/5550145/...
the tech market is crazy mann! it's one of the top indie fintech companies in our country and has a great valuation.
i totally felt that they i am crashing the interviews , and am seriously not trying to be humble. before the dsa round , i was trying to mug up how insertion sort works 🥲
--------
now my dilemma is should i switch if i get the offer. in a summary:
current company:
- small valuation but profitable (haven't picked funding for last 3 years , so poast valuation is some double digit million $, but can easily be a unicorn company)
- very major b2b player in my country. almost all unicorns (including this fintech company) and some major MNCs are their client and they have recently acquired a few other companies of us and eu too, making them- a decent global player
- meh work : i love being a cutting edge performer in android but here we make sdks that need to support even legacy banking apps. so tech stack is a lot of verbose java and daily routine includes making very minor changes to actual code and more towards adding tests , maintaining wrapper sdks in react/cordova/unity etc, checking client side code etc.
- awesome work life balance : since work is shit and i am fast enough, i am usually working only 2-4 hours a day. i joined gym, got into shape , and have already vsited 5 places in last 6 months, and i am a guy who didn't used to have time even on sundays. here, we get mote paid leaves than what i would usually need.
- learning opportunities: not exactly from the company codebase, but they provide unlimited access to various course learning platforms like linkedin learning, udemy and others, so i joined some web dev baches and i now know decent frontend too. plus those hybrid sdks also give a light context to new things
new company :
- positives : multi billion valuation, one of the top players in fintech , have been mostly profitable ( except a few quarters)
- positive : b2c so its (hopefully) going to put me back into racing shoes with kotlin, jetpack and latest libraries.
- more $$$ for your boy :)
- negetive : they seem to be on hiring spree and am afraid to junp ship after seeing the recent coinbase layoffs. fintech is scary these days
- negetive : if they are hiring people like me, then then they are probably hiring people worse than me 😂. although thats not my concern what my main concer is how they interviewed. they have hired a 3rd party company that takes interviews of people FOR THEM! i find that extremely impolite, like they don't even wanna spare their devs to hire people they are gonna work with. i find this a toxic, robotic culture and if these are the people in there then i would have a terrible time finding some buddy engineer or some helpful senior.
- negetive : most probably a bad wlb : i worked for an year for a fast paced b2c edtech startup. no matter how old these are , b2c are always shipping new stuff and are therefore hectic. i don't like the boredom here but i would miss the free time to workout :(
so ... any thoughts about it?4 -
“Here is an example for Kotlin programming language to develop Android app!” https://medium.com/@myinnos/...

Worst / best feature of any language:
Lack of / requirement of strict / dynamic / weak / strong typing. Just typing. Typing typing typing just typing.
Having to specify the type in C/++/#, Java/Kotlin is so annoying and delays the project so much by having to do declare weird classes with 3 or 4 fields just because you need it in this tiny line of code.
Not having good type support in JavaScript and Python is a pain in the eyes when you can't find what type each variable is, or when you pass a wrong argument to a function, and when you do, it shows the definition for the type in a .ty or.pyi file and not the definition itself which you have to find elsewhere. Spent half of my uni exams trying to decipher the type while it could've been a piece of cake if you just knew the type.
Love / hate relationship 😝1 -
Has anyone got experience in android development with both kotlin and java?
I am want to know if there are big differences if I migrate to kotlin. I have started learning Kotlin and it is unbelievable great so far. -
Is Kotlin the new hype? Should I go for java 8 or kotlin for development of android app? Also does anyone know any good course for ui/ux development(I am a backend developer)
-
Had an old classon "smart" Helmet(Brooklyness). App does work, company is looking dead. Reverse enginnered the app(android "beyong - micromobity"), quite simple if you have the apk file on hand. The fucker is kotlin which is compiled to Java, and uses AWS for User management(don't want it) and its data, even if a mobile is already required as relay to get the video files off the helmet into the cloud.
Never worked in kotlin and java, and never want to work in it ever again.2 -
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? -
So I have negligible experience doing mobile app development (simplish hello world Java app few years ago).
What's your advice to start getting into it? Flutter? Kotlin? I honestly dont have a clue. I want to target Android at first but very like this needs to support iOS as well.
I'm quite the experienced dev so I dont need some something to hold my hand, yet I dont have the time currently to fight a steep learning curve.3 -
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.5 -
Can we make any type of complex app app using react native?
or
Native Android app (Java) will be useful for complex app.
I need your suggestions.4 -
Java or kotlin for android mobile development ? And why ? I am still not convinced by kotlin at least just by myself but is it worth it ?8
