I tutor people who want to program, I don't ask anything for it, money wise, if they use my house as a learning space I may ask them to bring cookies or a pizza or something but on the whole I do it to help others learn who want to.
Now this in of itself is perfectly fine, I don't get financially screwed over or anything, but...
Fuck me if some students are horrendous!
To the best of my knowledge I've agreed to work with and help seven individuals, four female three male.
One male student never once began the study work and just repeatedly offered excuses and wanted to talk to me about how he'd screwed his life up. I mean that's unfortunate, but I'm not a people person, I don't really feel emotionally engaged with a relative stranger who quite openly admits they got addicted to porn and wasted two years furiously masturbating. Which is WAY more than I needed to know and made me more than a little uncomfortable. Ultimately lack of actually even starting the basic exercises I blocked him and stopped wasting my time.
The second dude I spoke to for exactly 48 hours before he wanted to smash my face in. Now, he was Indian (the geographical India not native American) and this is important, because he was a friend of a friend and I agreed to tutor however he was more interested in telling me how the Brits owed India reparations, which, being Scottish, I felt if anyone was owed reparations first, it's us, which he didn't take kindly too (something about the phrase "we've been fucked, longer and harder than you ever were and we don't demand reparations" didn't endear me any).
But again likewise, he wanted to talk about politics and proving he was a someone "I've been threatened in very real world ways, by some really bad people" didn't impress me, and I demonstrated my disinterest with "and I was set on fire once cos the college kids didn't like me".
He wouldn't practice, was constantly interested in bigging himself up, he was aggressive, confrontational and condescending, so I told him he was a dick, I wasn't interested in helping him and he can help himself. Last I heard he wasn't in the country anymore.
The third guy... Absolute waste of time... We were in the same computer science college class, I went to university and did more, he dossed around and a few years later went into design and found he wanted to program and got in touch. He completes the code schools courses and understandably doesn't quite know what to do next, so he asks a few questions and declares he wants to learn full stack web development. Quickly. I say it isn't easy especially if it's your first real project but if one is determined, it isn't impossible.
This guy was 30 and wanted to retire at 35 and so time was of the essence. I'm up for the challenge, and so because he only knows JavaScript (including prototypes, callbacks and events) I tell him about nodejs and explain that it's a little more tricky but it does mean he can learn all the basis without learning another language.
About six months of sporadic development where I send him exercises and quizzes to try, more often than not he'd answer with "I don't know" after me repeatedly saying "if you don't know, type the program out and study what it does then try to see why!".
The excuses became predicable, couldn't study, playing soccer, couldn't study watching bake off, couldn't study, couldn't study.
Eventually he buys a book on the mean stack and I agree to go through it chapter by chapter with him, and on one particular chapter where I'm trying to help him, he keeps interrupting with "so could I apply for this job?" "What about this job?" And it's getting frustrating cos I'm trying to hold my code and his in my head and come up with a real world analogy to explain a concept and he finally interrupts with "would your company take me on?"
I'm done.
"Do you want the honest unabridged truth?"
"Yes, I'd really like to know what I need to do!"
"You are learning JavaScript, and trying to also learn computer science techniques and terms all at the same time. Frankly, to the industry, you know nothing. A C developer with a PHD was interviewed and upon leaving the office was made a laughing stock of because he seemed to not know the difference between pass by value and pass by reference. You'd be laughed right out the building because as of right now, you know nothing. You don't. Now how you respond to this critique is your choice, you can either admit what I'm saying is true and put some fucking effort into studying cos I'm putting more effort into teaching than you are studying, or you can take what I'm saying as a full on attack, give up and think of me as the bad guy. Your choice, if you are ready to really study, you can text me in the morning for now I'm going to bed."
The next day I got a text "I was thinking about what you said and... I think I'm not going to bother with this full stack stuff it's just too hard, thought you should know."22 -

This was over a year ago now, but my first PR at my current job was +6,249/-1,545,334 loc. Here is how that happened... When I joined the company and saw the code I was supposed to work on I kind of freaked out. The project was set up in the most ass-backward way with some sort of bootstrap boilerplate sample app thing with its own build process inside a subfolder of the main angular project. The angular app used all the CSS, fonts, icons, etc. from the boilerplate app and referenced the assets directly. If you needed to make changes to the CSS, fonts, icons, etc you would need to cd into the boilerplate app directory, make the changes, run a Gulp build that compiled things there, then cd back to the main directory and run Grunt build (thats right, both grunt and gulp) that then built the angular app and referenced the compiled assets inside the boilerplate directory. One simple CSS change would take 2 minutes to test at minimum.
I told them I needed at least a week to overhaul the app before I felt like I could do any real work. Here were the horrors I found along the way.
- All compiled (unminified) assets (both CSS and JS) were committed to git, including vendor code such as jQuery and Bootstrap.
- All bower components were committed to git (ALL their source code, documentation, etc, not just the one dist/minified JS file we referenced).
- The Grunt build was set up by someone who had no idea what they were doing. Every SINGLE file or dependency that needed to be copied to the build folder was listed one by one in a HUGE config.json file instead of using pattern matching like `assets/images/*`.
- All the example code from the boilerplate and multiple jQuery spaghetti sample apps from the boilerplate were committed to git, as well as ALL the documentation too. There was literally a `git clone` of the boilerplate repo inside a folder in the app.
- There were two separate copies of Bootstrap 3 being compiled from source. One inside the boilerplate folder and one at the angular app level. They were both included on the page, so literally every single CSS rule was overridden by the second copy of bootstrap. Oh, and because bootstrap source was included and commited and built from source, the actual bootstrap source files had been edited by developers to change styles (instead of overriding them) so there was no replacing it with an OOTB minified version.
- It is an angular app but there were multiple jQuery libraries included and relied upon and used for actual in-app functionality behavior. And, beyond that, even though angular includes many native ways to do XHR requests (using $resource or $http), there were numerous places in the app where there were `XMLHttpRequest`s intermixed with angular code.
- There was no live reloading for local development, meaning if I wanted to make one CSS change I had to stop my server, run a build, start again (about 2 minutes total). They seemed to think this was fine.
- All this monstrosity was handled by a single massive Gruntfile that was over 2000loc. When all my hacking and slashing was done, I reduced this to ~140loc.
- There were developer's (I use that term loosely) *PERSONAL AWS ACCESS KEYS* hardcoded into the source code (remember, this is a web end app, so this was in every user's browser) in order to do file uploads. Of course when I checked in AWS, those keys had full admin access to absolutely everything in AWS.
- The entire unminified AWS Javascript SDK was included on the page and not used or referenced (~1.5mb)
- There was no error handling or reporting. An API error would just result in nothing happening on the front end, so the user would usually just click and click again, re-triggering the same error. There was also no error reporting software installed (NewRelic, Rollbar, etc) so we had no idea when our users encountered errors on the front end. The previous developers would literally guide users who were experiencing issues through opening their console in dev tools and have them screenshot the error and send it to them.
- I could go on and on...
This is why you hire a real front-end engineer to build your web app instead of the cheapest contractors you can find from Ukraine.

"Fuck JavaScript, its such a shitty language" seems to be quite a common rant today. It seems as if JS is actually getting more hate than PHP, which is certainly odd, considering the stereotype.
So, as someone who has spent a lot of time in JS and a lot of time elsewhere, here are my views. Please, discuss your opinions with me as well. I am genuinely interested in an intelligent conversation about this topic.
So here's my background: learned HTML/CSS/JS in that order when I was 12 because I liked computers. I was pretty shitty at JS until U was at least 15, but you get the point, Ive had it sploshing about in my brain for a while.
Now, JS certainly has its quirks, no doubt, but theres nothing about the language itself that I would say makes it shitty. Its a very easy leanguage to use, but isn't overdeveloped like VB.net (Or, as I like to call it, TheresAFunctionForThat)
Most of the hate is centered around JS being used for a very broad range of systems. I doubt JS would be in the rant feed so often if it were to stay in its native ecosystem of web browsers. JS can be used in server backend, web frontent, desktop and mobile applications, and even in some system services (Although this isn't very popular as of yet). People seem to be terrified that one very easy to learn language can go so far. And, oh god, its interpreted... How can a system app run off an interpreted language? That's absurd.
My opinion on JSEverything is that it's progress. Thats what we're all about, right? The technologies already in place are unthreatened by JS, it isn't a gamechanger. The only thing JS integration is doing is making tedius and simple tasks easier. Big companies with large systems aren't going to jump ship and migrate to JS. A startup, however, could save a fucking ton of development time by using a JS framework, however. I want to live in a world where startups can become the next Google, because technology will stagnate when youre trying to protect your fortune, (Look at Apple for fucks sake) but innovation is born of small people with big ideas.
I have a feeling the hate for JS is coming from fear of abandoning what you're already doing. You don't have to do that. JS is only another option (And a very good one, which is why it's becoming so popular).
As for my personal opinion from my experiences... I've left this part til the end on purpose. I love programming and learning and creating, so I've never hated a lamguage, really. It all depends on what I want to do. In the times i've played arpund with JS, I've loved it. Very very easy. The idea of having it on both ends of web development makes a lot of sense too, no conversion, just direct communication. I would imagine this really helps with speed, as well. I wouldn't use it in a complicated system, though. Small things, medium size projects: perfect. Running a bank? No.
So what do you think about this JSUniverse?13 -
Am I the only one who hates it that everything needs to be done in JavaScript nowadays?
Why can't you just start writing native software again? Why does every program need its own fucking browser engine and at least 200MB of RAM to do nothing but show and edit text?
I want to have fast and streamlined software again and use my resources for important things. So much software that is called fast or lightweight isn't either. It's just a little less heavy and slow than the software it tries to replace.
I don't use C all the time, but maybe looking into Qt instead of electron might be a start.
I had a project where I could convince my tutors to let me use C++ instead of JS and they were surprised how fast my application started even though it only consisted only of a empty window with a status bar. How far have we come that we even need to think about performance when opening an empty window on modern hardware?20 -
Went to hackathon @ Google HQ in NYC. Gotta say it was pretty shitty. Most people are JavaScript nerds and some code in objective-C, xcode (4-5 out of 50). The rest are chemists, scientists and general folks. Not what I anticipated when you know it's more like iOS hackathon. Anyways it was good to see the shittiest demos in my life made in less than 12 hours. We had 4.5 people working on a toilet project called "I gotta go". Public bathroom locator... One guy coded in JS, xcode and react Native. Another dude was pushing all the code to GitHub and doing backend in firebase. The third guy was making a website for no reason and then I see it's hosted weebly. He hand coded first, I looked what he is doing - just HTML tags. Thank God some organizers helped us and we had a 4 click demo with basic text and no real functionality. Plus the website who never seen. What a fucking waste of $100 and two days.4

This is pretty much how I understand Native JavaScript, Vue and Vuex.

Today I learned that someone wrote a Python interpreter in JavaScript called Brython. So now you can include a framework to write shitty code in a buggy framework and tell your users to throw more hardware at it.
The guy I heard this from also believed that his code would somehow be "compiled" rather than what's essentially a framework be loaded and then execute code in a language not native to the browser...
So now you can write JavaScript where it doesn't belong in Node and write Python where it doesn't belong through a framework. Frontend and backend are so passé, we might as well start calling it fluid instead.
FULLSCHTAK!!!

I should not have looked at this really interesting Chrome extension.
https://chrome.google.com/webstore/...
It tries to prevent phishing links from working by adding attributes to change the behaviour of the browser.
HOW DOES THIS WORK?
Just one simple line:
$('[target="_blank"]').attr("rel", "noopener noreferrer");
But why is this extension so bloated?
It loads the full jQuery library. For an attribute change!
I'd like to refer to this site for further investigations: http://youmightnotneedjquery.com//...

Three years ago, tried to learn some JavaScript, failed miserably. Two years ago, managed to learn some Java through Udacity courses. Last year I started learning native Android development and got my first coding summer job. Now I'm back to learning JavaScript through Freecodecamp and that bitch ain't got shit on me no more!3

I'll admit - I come from a WordPress background of almost 9 years in the making. I guess I can justify it because of all of the sites I created using it, it was the best that it could be on WP. Fast, efficient, custom - none of that off-the-shelf themeforest crap. I created everything custom. I actually knew what was going on behind the scenes of WP.
And then a buddy of mine and I had an idea for a new company/software project. I was smart enough to know that WP was not the foundation for this, so I did some NodeJS/Express tutorials. Started learning React, and really getting into the Javascript world.
And now I'm wondering WHY IN THE ABSOLUTE FUCK I ever bothered trying to become an expert in WP. It's the largest use of PHP in the fucking world and it doesn't even have native composer support. And by the time you actually get your project set up using composer you have to add a fucking mirror of the wordpress.org plugin repo to get anything to work. It's 2018 and you'd think that WP and composer would have all of this shit figured out by now.
And don't get me started on git - as soon as you have more than 1 person working on a WP site, I hope you have hourly backups of your DB because someones work will get overwritten. So you all either need to work on the same staging area of work around each other by pushing/pulling the DB and schedule your workflows.
I guess WP CLI and the REST API are a step in the right direction, but the foundation of everything is just so fucked up.
I don't feel like I've wasted my web dev career, but I definitely wish I had started down this path a lot earlier. I guess you don't know what you don't know. Thanks for reading!2 -
I'm starting to get sick of people calling out js for being what it is, a terrible pile of shit, without taking any effort learning the language. just because you wrote an app in java or python doesn't mean you're entitled to a free certificate in any language with a name that makes it sound easier.
in fact, I'd claim that for an experienced programmer, Java is much easier to pick up than JavaScript.
but, if all you want to do is sit here and complain, and you can find no joy in reading pages on end of documentation... well then, the only thing you're missing out on is the biggest fucking platform of the world. so don't worry I guess. it'll be fine. right? eventually the users will see that the web is just a nuisance for developers and they'll all start using native apps...6 -
I can't tell you how much I hate people who make articles doing relatively simple things, in node, and instead of showing how to do it, they proceed tell you to install a fucking package (usually made by them)
Yeah no thanks, it's great that you figured this out and took the time to "enlighten" other devs but I'll just look at your repo and use the native JavaScript functions you wrapped on myEgoInflatingPagacke.justAWrapperHuehue(). Bye.1 -
Just a personal request to @dfox
Can you screenshot only the part of the behind the scenes code of devrant? Just the part of it.
I want to see the syntax and how the language is used.
Thanks.24 -
Effective working days are only 4 days left before everyone left for holiday,
Sprint zero has started though most of the people also has started their holiday leave,
Got a mandate to conduct a sharing session for some developers who was pressured by their manager to join, has never touched any javascript and has to be proficient in React Native within 3 days of workshop before year’s end,
To put it simply, everyone are already in holiday mood and unmotivated as fuck, how the fuck am I supposed to conduct a useful training while being pressured to set up everything for a project that is still unclear as whether we’re gonna go through with it or not,
Fucking “do first think later” mentality,

I’m a long time Objective-C and Swift developer...I’ve been asked to “research” a project using React Native.
It felt dirty to be writing an iOS app using JavaScript.
I’m still not sure why and how React Native is better/faster than native Swift.
Someone change my mind...11 -
I've been an iOS developer for a number of years now. I like learning new technologies and approaches, but recently I've been getting more and more frustrated by how complex and fast paced everything is becoming.
It used to be that you had to know Objective-C and UIKit and you were set. Then things like unit and ui testing became popular. Swift came out with its set of fancy features and different way of seeing things. Everyone wants to use some sort of architecture. The number of frameworks released just by Apple is mind boggling and getting any sort of exposure to most of them works be a full fine work. Then there is the whole third party ecosystem. There are so many tools and frameworks for everything (which are popular) that I can't even keep up with the new names I keep coming across.
Sure, I can learn new things, I like doing it. However, recently i I've applied to a company and they wanted knowledge of RxSwift. Well, experience, possibly writing a full blown app from beginning to the end. And it had to be highest possible quality, not a kind of "look, I know RxSwift, I can write apps in it, I'll learn more as I go along".
Other place wanted experience in the continuous integration system and ui testing framework that they use. And they expected to to know a lot about one of the many architecture you can use.
Then there is a lot of places that want you to know React Native. Sure, JavaScript is not complicated and the framework simplifies development, but getting to know the tools, creating a toy app, going through a lot of mistakes takes a lot of time. And of course you have to have demonstrable experience in it. Best if you've released an app written in it.
Then you're expected to be involved in the community. Side projects, open source projects. I've been getting the impression that it's becoming more and more about building your personal brand.
In short, I've been getting tired of all of that. It's exciting, but the expectations I find overwhelming. If I start learning a third new thing, I'm going to forget the first one. I miss the simplicity and the clarity of the early days of mobile development.4 -
Javascript is becoming the mostly used language in the entire stack of technology. You can create mobile apps, websites, desktop apps etc... using javascript. Will this be the end of native programming languages?19
-
Things I hate the most at the moment:
- PHP
- jQuery
- The person that coded this before me
- The fact that this person is swtiching from jQuery and native javascript over and over for no f*cking reason. Just why?
- My job
- My boss
- The big pile of sh*it that this code is (overall not just the screenshot), no separation of concern, logic code in the middle of the file, no proper slacing and indentation
- devRant no allowing me to put multiple images in one post, because the picture is just one of this whole mess, it's not even the worst part, you'd have nightmare if I showed it to you
- The mental breakdown I'm having
16 -
That feeling when you were so happy about react-native, and was pretty sure at the beggining about the achitecture of your app and js libs you are about to use.
Im here sitting with redux, reselect and still dont know why I cant just do a REST call and format data in the container component.
Why react is so hard, or am I dumb?6 -
I can't remember the last time I had THIS MUCH FUN developing an Android app! 😳 Have a paper due, but learning RN is actually making this pet project a huge distraction! 😳 This is a whole new world of mobile development 😆, but what if another framework takes it's place 😵. But there's still people who know Angular, and that's widely used...right 😓 and moble dev has never been this easy, so maybe it'll stick around like Node...
who cares... I'M FUCKING LOVING React Native now!!! 😆

Developer vs non developer interview:
Non developer:
How well do you know excel ?
Developer:
How would you write spreadsheet app, what if it was cross platforms mobile application but also desktop app ?
Non developer:
Do you know how to use windows?
Developer:
Do you know kubernetes, distributed systems, lambdas, cloud services and how to deploy to server farm ?
Non developer:
You know how to use printer / fax and coffee machine ?
Developer:
Do you have experience in writing code for embedded devices ?
Non developer:
Do you know powerpoint ?
Developer:
How well do you know javascript / html / css, are you comfortable with writing backend node.js code or electron applications ?
React native and native apps maybe ?5 -
Working on an Android app for a client who has a dev team that is developing a web app in with ember js / rails. These folks are "in charge" of the endpoints our app needs to function. Now as a native developer, I'm not a hater of a web apps way of doing things but with this particular app their dev teams seems to think that all programming languages can parse json as dynamically as javascript...
Exhibit A:
- Sample Endpoint Documentation
* GetImportantInfo
* Params: $id // id of info to get details of
* Endpoint: get-info/$id
* Method: GET
* Entity Return {SampleInfoModel}
- Example API calls in desktop REST client
* get-info/1
- response
{
"a" : 0,
"b" : false,
"c" : null
}
* get-info/2
- response
{
"a" : [null, "random date stamp"],
"b" : 3.14,
"c" : {
"z" : false,
"y" : 0.5
}
}
* get-info/3
- response
{
"a" : "false" // yes as a string
"b" : "yellow"
"c" : 1.75
}
Look, I get that js and ruby have dynamic types and a string can become a float can become a Boolean can become a cat can become an anvil. But that mess is very difficult to parse and make sense of in a stack that relies on static types.
After writing a million switch statements with cases like "is Float" or "is String" from kotlin's Any type // alias for java.Object, I throw my hands in the air and tell my boss we need to get on the phone with these folks. He agrees and we schedules a day that their main developer can come to our shop to "show us the ropes".
So the day comes and this guy shows up with his mac book pro and skinny jeans. We begin showing him the different data types coming back and explain how its bad for performance and can lead to bugs in the future if the model structure changes between different call params. He matter of factually has an epiphany and exclaims "OHHHHHH! I got you covered dawg!" and begins click clacking on his laptop to make sense of it all. We decide not to disturb him any more so he can keep working.
3 hours goes by...
He burst out of our conference room shouting "I am the greatest coder in the world! There's no problem I can't solve! Test it now!"
Weary, we begin testing the endpoints in our REST clients....
His magic fix, every single response is a quoted string of json:
example:
- old response
{
"foo" : "bar"
}
- new "improved" response
"{ \"foo\" : \"bar\" }"
smh....8 -
Just a quick rant on JavaScript,
So there’s a lot of people hating javascript, and while not a long time ago i was part of them, but I changed my opinion a little.
I think JavaScript is a great way to deal with website programming as it is quick and efficient, but I would not say to program directly on it, use a js-compilable language (CoffeScript, TypeScript, Kotlin(I think), etc.), but then you might say: “Well, no need for js then, compile it in byte code”. That would break the point of how I see web design/dev. The main intent behind webpages is to have an easy and fast way to send code to other computers to render them, that’s why it is interpreted: “Easy to send” and “*All* computers can handle it” with the proper browser. You need to be able to change the way the website is rendered and/or works sometimes, for diverse reasons like copy/pasting data, make it render properly or use plugins/add-ons to change that code to suit your needs.
I think js should be kept as a “readable byte-code”, so that means: {
Keep comments when compiling the js-compilable code,
Add standardized machine-readable comments that will indicate to smart code viewers how to show a particular thing (Like have a higher-end function compiled in js shown as a minimized code with explanations of the function)
Keep it nicely formated and don’t obfuscate (coz that’s annoying)
Etc.
}
So you bypass the quirks and all that pesky js stuff, while keeping it’s good sides.
-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-
Part 2:
Web design for non-web:
Ok so things like node.js, electron, react-native and all that stuff; I won’t say they’re bad but...
Why we have this is because web designers wanted to make desktop apps and were like “Hey! Making web pages is easy! Let’s port it to desktop”, the problem is: Web technologies were made to work on a restricted canvas, aka a browser. It’s good on web for reasons mention earlier and more. But it’s not on desktop! You’re trying to push it outside of those boundaries. It’s difficult to make it break that canvas and go outside, make something that really works! For social media clients and that kind of stuff that you want to make a little more inclusive, yes! it’s a great idea (hello devrantron ;), but not if it’s an exact same copy of the website, just use the website. But for things that are supposed to really make use of YOUR computer; no!
I see those PWA (progressive webapps aka mobile app, but it’s an offline website”), I stand for the same positions, social media and those sort of things: yes, great idea! Games? 🤢.
I have way more to say but I have difficulties to remember them while reading, so feel free to comment your thoughts
Lol, “just a quick rant”1 -
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 Java21 -
Having developer skills comes sometimes in handy in certain situations.
In my case I visited a new website but first I had to choose their cookies.. but.. it was a list of about 150 radio buttons (150 advertisers), I shit you not.
And so I was like: "No, I refuse to click each one of them". I kept thinking.. hm.. how am I going to do a mass-toggle-off? And then it hit me: if the button "toggle all" toggles all buttons.. then that means if I invert the logic of the call, it means I will turn them all off! And it worked.. it was something like: "toggleAll(!-1)" and I did "toggleAll(0)".
That sure saved me some time! Oh yeah and there are of course other situations when you don't want to use a scraper for getting all the;. I don't know.. menu links out of a page. Console > import jQuery > select all elements with 'a' and text() on their DOM node! It can be done with native JavaScript as well document.getElementsById() but yeah, there are plenty of examples.
Hooray for being a developer!2 -
Have a question about my career:
So far my career out of uni has been like this:
8 months in first place working as C# .NET dev, creating native desktop apps for windows. job was shitty, was not getting any best practices skills so I left.
12 months in 2nd place working as android dev in a startup. was working all alone and had to rebuilt my app up to 5-6 times to learn best practices. startup didnt care about android app at all so I left and now doing just some small freelance work for them.
3 months in new startup as android dev.Today I was told that its decided to focus on iOS and do all marketing (also uplift of new design) only on iOS. basically for next 3-4 months they don't plan to do much on android side. they saw that I showed some interest in backend and now they are asking me to talk with two other senior guys about starting with some small tasks for me on backend.
Our backend is mainly using python. Also backend guys will be pretty busy for next few months because they will have to deliver many new features in next few upcoming months. I've talked with one of them and he said that this is a bad idea to force frontend to start working on backend. However I feel that he's sort of gateekeping and probably just doesn't want to help me with getting up to speed.
In my defense, my knowledge doesn't end with C# .NET desktop apps and native mobile apps for android.
I have hobbie projects (gameservers) where I worked on websites (php,html,css,javascript,mysql) and also was taking care of a java based gameserver which is hosted in a linux vps.
Also I've had a small hosting "company" where with available tools I've managed to automate VPS(virtual private server) ordering, web hosting ordering and domain ordering. Basically I owned a dedicated server and did everything using whmcs, cpanel and proxmox virtualization.
I trust myself in learning this backend stuff and doing whats required, however I learned everything by myself and I won't follow all of these best practices.
Should I accept more responsibility on backend or should I continue focusing on android?7 -
Planning to make a github list of usefull links on topics related to javascript,react,react native,redux etc . Drop usefull links if you have any. They can be tutorials,articles, talks,repos,packages etc.1

BANano, a free library that transpiles B4X (a crossplatform development tool) source code to JavaScript.
It allows users who are not fluent in JavaScript to make PWA's and dynamic Websites using a VB-like language and the Abstract Designer native to the B4X tool.

On a website, using var something = $.parseJSON('{"with": "perfectly valid javascript in here"}') when you could just have done var something = {"native": "javascript goes here", "with": "no parsing needed"};

TL;DR: if you are using using react native, use uglify-es@3.2.2, any newer version might break your project
I wonder how many react native projects the boys at Mishoo fucked up, mine included.
I spent 5 work days to find an unrelated issue on RN's git which had the solution to my issue in the comments which was totally different from what was being presented in the issue.
Fucking aye.
I love javascript, but packaging really is its downfall.1 -
So i'm visiting the JavaScript bubble every now and then when i'm writing on the userscript i develop to fix bugs in our ticketing system or fix some clients website they negelected. Every time i'm searching for answers to the weird problems that inevitably turn up i have to filter out all the threads that derail with the classic 'google jQuery basic arithmetic plugin' craziness to find an actual vanilla solution to my problem.
All the time i wonder why on earth people put up with this framework hell. This is part serious question and part rant but seriously, how did we come to this? With all that jQuery, React, Node, whatever stuff i'm kinda losing the overview over what's even todays standard. I always try to keep my code as vanilla as possible without using external libraries. But it seems the entire web development industry is heading the completly other way. I tried to look into a few frameworks but i never really see the appeal. Just now i looked up react native because the last 20 rants talked about it and immediately noped out because they fucking create a DOM in js, why the fuck would you do this?!
Worst thing about this framework shithole is that some frameworks are beeing pulled into the mix for very weird and unnecessary reasons. Best example is a charts library i recently used to visualize a database of temperatures that was completely written in native js but pulled jQuery in for the equivalent of window.addEventListener('load',function(stuff)) and i was furious. I rewrote the code and could throw out the jQuery dependency with no problem. What the fuck is wrong with people?
Alright since you made it here: I'm not trying to throw any of you under the bus for using frameworks. I just fail to understand why you would use these. To each their own and unless your site has the performance of the ticketing system i use at work that takes like 15 seconds to load one fucking page i won't complain at all. But pull in a framework just to do a task you can easily do in native js in remotely the same timeframe you are on my list.2 -
One of the projects that I have to do this semester is a React-Native, I was very eager to start coding until a friend of mine got an error never seen before, when he googled the problem, literally in StackOverflow somebody posted the same issue just about 2h ago, still with no response. This is going to be a fun ending semester project.
PS: this project is going to have a Lisp code project connected somehow4 -
I opened "About" screen
I read "Write native Android/IOS apps with JavaScript"
A second later: "devRant stopped unexpectedly"
Okay :D -
Eval is evil. I heard it often. So apparently, they put it there just merely to test you, whether you are a sinful coder deserving eternal damnation or not...
So, one thing I don't really like from people is sometimes they just believe in things without questioning anything. And worst... sometimes they get offended when some random poor guy ask a sensible question regarding to the belief.
Just because Richard Stallman said vi is evil, then they hate every vim users in the world.
Just because this easy-but-effective solution is not PSR-3 compliant, then they ditch it at all...
Ok, back to the eval-is-evil thing.
Yesterday, I show some part of code using safe-eval npm package to someone. And the reaction is like "yike... it's eval..."
So yes, eval is evil. But only if it's miss-used, just like anything else...
The drawbacks of eval are:
1. Security. Sometimes people miss-use the eval by allowing user's script to be evaluated without double checked. The problem here is not eval-is-evil. However, sometimes your user is. So how about creating powerful ionic-based calculator to evaluate javascript because you are too lazy to create that infix-postfix parser? I don't really like when people argue without argument. Something like "I don't know, but eval is evil and it is". Why? why? and why?....
2. Performance. Eval is slow. Yes it is, because it is running a parser inside a parser. So it is just a mere calculator. And yes, it is slower 100 ms than native program. Problem?
3. Untrace-able error stack. But again, you just use that eval once. And if it is trowing an error, just catch it and let the user know that his input is wrong. Problem?
No, there is no real problem here. It's just eval is evil and it is...10 -
I think it's still ok if I erase other skills in my resume and left only with JavaScript. Holy crap JavaScript today unlike back in the days people think you're able to prompt user a client side, it's now another kind of alien. Es6 and stuff like react and react native. Master javaScript make me worth lot more than before. Not a rant :)1
-
A lot of people have already said it but I'm gonna say it again: Javascript. I think that we will be able to code everything in JS, in addition to its native language.1

Best Explanation I found of every(), filter(), map(), some() and foreach() methods in Javascript
(at least for me as a non-js dev)

I like rants that are thought provoking and push a message forward regardless of whether they may sting a little, so for my first post on here I'd like to hit at home with many of you.
Html5 "Native" Applications are not needed. Let's cover mobile first of all, the misconception that apps are written in either javascript or Native android/ Native ios environment. Or even some third party paid tools like xamarin is quite strange to me. OpenGL ES is on both IOS and Android there is no difference. It's quite easy to write once run everywhere but with native performance and not having to jump through js when it's not needed. Personally I never want to see html or css if I'm working on a mobile app or desktop. Which brings me to desktop, I can't begin to describe how unthought out an electron app is. Memory usage, storage space for embedding chromium, web views gained at the expense of literally everything else, cross platform desktop development has been around for decades, openGL is everywhere enough said. Finally what about targeting browser if your writing a native app for mobile and desktop let's say in c++ and it's not in javascript how can it turn back into javascript, well luckily c++ has emscripten which does that simply put, or you could be using a cross complier language like haxe which is what I use. It benefits with type safety, while exporting both c++ and javascript code. Conclusion in reality I see the appeal to the js ecosystem it's large filled with big companies trying to make js cross development stronger every day. However development in my mind should be a series of choices, choices that are invisible don't help anyone, regardless of the popularity of the choice, or the skill required.8 -
Hello everbody!
For college I'm doing a small research project. The goal of my research is give advice to web developers on using JavaScript frameworks to create mobile applications and help them decide which framework to use by comparing 3 popular frameworks. I decided to compare React Native, Ionic and NativeScript. I myself have only used React Native to build a mobile application. I would like to get some opinions from other developers on this matter. I want to compare the frameworks based on the following categories: developing time, performance, debugging an learning curve. Are there developers here who would be willing to write their experience with these frameworks? Or maybe some of you know a forum or other place where I can ask for some help:)3 -
!Rant - I'm looking for some advice 🤔
So this kid he's 13 interested in building cool things programming etc hasn't had any real start in it.
So I'm like ! Great! 🤔
Another programmer in this world would be lovely ... Before I used to take this approach of, you should do ... This.
Now I'm taking the approach, well what do you like what interests you 🤔 what do you find yourself needing?
Effectively trying to find an in, Into what might drive him to keep with it.
I find people get to ... Uninterested in it. Fast. I've literally had 10-20 people go 🤔 I would like to find out more I really like this etc .
But most don't stick with it I feel because I suggest they make this start and they aren't interested in.... That specifically even though it's a steeping stone
Normally I suggest html CSS right. It's a simple easy thing to learn
Then JavaScript then ... Another language like c# and move to c++ etc.
It's not what I did but I think it's... A smoother transition then my c# start then dropping to c++ then web
So opinions ? Is this the right move 🤔 he has this project in mind now. This app. Which I said could be built in html CSS really if he wanted to. Or though I suggested looking at some native stuff to, then pick.
I've left it open said he can ask anytime. I sent him codeacademy fyi
I told him to get this app to 😂 so might be on here9 -
Suggestion please!
I work basically on native android applications. From last week I started exploring cross platform and chose React native. I have zero knowledge on JS. And now it seems very hard to grab. I started a project and learning whatever I'm needing on that purpose. Some props I'm shooting blindly and components I don't even understand clearly how they are working.
Please suggest me a convenient way or guide me with some resources to alleviate my frustration! Pretty please!4 -
Javascript and Java.
Imagine java is an indigenous language to an island spoken by everyone there.
A non-native visits, and in order to understand them they need to decode their java into meanings and reapply those meanings to their own language.
More non-natives start visiting more and more often, and the javanese naively welcome them in.
The natives happily create trinkets and souvenirs for the tourists, and a market starts forming. The docks get busier every day.
Soon it appears that there are more non-natives on the island than natives, and their polity of origin starts to lay claim to their land.
Fights and legal altercations become common.
Some of the native javanese begin to modify their language to meet the colonists halfway, and some of the colonists begin to learn this new language.
They begin to understand each other more fundamentally and tensions fade.
Meanwhile, the more stoic javanese retain their claim to the island, and fight the pidgin "rebels".
The island splits into Java and Papua New Java. The populace of both claiming having nothing much to do with the other.
Nothing but fun and funerals for any new tourism.
It's so sad.
Let's Make Java Great Again.
Let's Make Papua New Java Great Again.
Let's build a wall. -
Just hate it when managers assume it takes the same freakin time to implement the same feature on a native app and a fully responsive web app! FML!
-
Here developing a react native app using console.log everywhere cause the debugger won't stop at the right line or skip libraries when stepping.
But I still somewhat like RN 💙 I think it's a fairly ok framework when you get the hang of it.
I was thinking about giving Flutter a try though, and see how easy it is to use. What do you think about this library?2 -
Looking to write a mobile application targeting both iOS and Android. It will be fairly basic (most complicated functions will be push notifications, asynchronous JSON fetching). I am fairly proficient at both Swift and iOS as well as JavaScript web development (react) but have never tried react native. Any thoughts on React Native vs Native Swift / Java?4
-
If somebody wants to become famous for the work they do fast. Join DIY projects such as React-Native.
You can become so famous for developing a highly demanded component, since there arent many well maintained this days.
I guess it is the case for many new and fresh projects.
React is awesome and react-native is the beast for cross platform development! You gonna love it guys! Jump in! -
I'm curious about which kind of pattern/architecture you are using in your react native apps (big ones).
-
Was interested to learn React native, started with the demo project too. But then *bam* Flutter shows up with butter smooth UI and it's all new features.
Well, now I'm in a dilemma as to where I need to direct my 'learning bandwidth'. I'm a huge fan of JavaScript, it's my fav language. Also Dart feels lot like JavaScript.
What do you guys think? Any suggestions and experience are welcome..2 -
Anyone here does use dartjs for basics as an alternative to javascript?
I hate js so much, that I am planning to give dartjs a try and in case I will like it, I would like to rewrite UI widgets in it (dropdowns, datepickers, modals, accordions, dropzones and other casual shit) to ease up my life in frontend and avoid using huge frameworks for that (like jquery or reactjs).
It also makes sense to adopt it for my current company, as we do a lot of mobile app dev with react native.
Anyway, it would be nice to hear experiences from other devs first.7 -
So this is a simple calculator I created by using react native. Pretty useful.
However, if you see it on google playstore, please give a negative rate on it. And if you have accidentally install this app, please uninstall it and re-implement your own javascript parser instead.
A very critical bug was found in this pitty app. Everything works well, but it has this line in it:
safeEval(userInput)
Please don't install this app, or it will corrupt your soul. Again, please create your very own javascript instead, because you are a demigod-developer loved by PSR and any other standard.
For me? Oh I'm a wreck stupid script kiddies who use eval that too lazy to create a so called clean solution...
Also, this funny ecma script foundation put this eval thing so that you should not use it ever...
I heard a similar funny-but-ironic story about a Supernatural Entity who put a pity apple tree in the garden of eden, so that, everyone eat it's fruit become pricky mother fucker who never listen at anyone's argument. They blindly follow everything told by the linter. Because the linter is a perfect entity who knows your use case more than you.
And I'm really sorry, I'm just a sad moron script kiddies, please -- this rant and tell me again why eval is evil.
Because I'm too stupid to understand the risk of using eval, even if it is safe-eval. Also, tell me again this safe-eval is not save if I accidentally put global context as argument. I don't do it, but let's consider this possibility as bug...
No, mother fucker, you are not superior. You are just an asshole trying to act cool. You say something is dirty, and you don't provide any cleaner solution. Why? because you are a knight with shining armor. A certified developer who never goes to real battlefield. It is always fun right?, to see how people doing things "wrongly" and make fun of it without doing anything...
Ah, don't worry, you don't need to know how to do things correctly. You only need to pray to your linter 12 times a day in order to feel superior...

I love how easy it is to build a native app these days thanks to tools like react native but also hate convoluted it becomes of you want to do anything “outside of the box”

Le Angular programmer
Me: I need to add all these fields across this 30 page (seriously) questionnaire to the dataLayer for Google Analytics...I'll see if I can loop over all the controls and get the native element so that I can do things with it.
Also me: WTF do you mean I don't have access to the native element? Damn it! What does Google say?
**terrible french accent**
A few moments later
**end terrible french accent**
Me: I don't want to have to create a directive to put on every single one of these fields. That's dumb. Not gonna do it...bad vanilla JavaScript?
**terrible french accent**
Several minutes later
**end terrible french accent**
Me: Wait...if we use this directive then the directive can handle all the things AND we can use it outside of this questionnaire. The rest of the app can send this data so that Google Analytics can know all the things
Man Google..You sure do know what I want before I know what I want...Are you spying on me too?1 -
imagine building an app using javascript(react-native) that get list of skills which will be displayed to the user to select and the same list displayed as interest for the user to do the same if you try to treat them seperately but from the same source you get a shit result e.g
const list = responseFromApi;//array of object
let skills = list;;
let interest = list;
skills.checked = true;
interest is changed and the list constant variable is changed the values change were ever the list variable is assign to a variable and the variable is tempered.
the above code was the fustration i got with javascript when i didnt know of the mutation guy.
Mutation is a nightmare never knew javascript object are passed by reference which make them mutable this sucks....
another crazy behavior below though the same;
const person = {name:'Dan',age:43} //object
let person0 = person;
let person1 = person;
person1.name = 'David'
the value of both person0 and person get change.
this is madness .3 -
While logging a boatload of bugs on the code my junior dev checked in, I added a couple of items to our product backlog.
Instead of fixing his bugs, junior dev started pulling things from the backlog. I found this out when he messaged me about the requested search results sorting.
His message was:
"hey, the sorting is going to be harder than I thought. Angular 2 dropped native support of filters. But I did find an MIT licensed npm package that should let me add sorting functionality to our JSON data objects. "
Um... You know you can sort using plain JavaScript, right?
BTW, junior dev has more than 3 years of professional experience in addition to a degree.6 -
How good is React Native? Should I bother learning Javascript for it? Can I make an app just as I would in Swift? Need someone to convince me.1
-
Can anyone share their thoughts/opinion about jQuery?
I'm already using jQuery but I always have a doubt in my mind that using this library cause to lessen the performance or slow our webapps.
And also I was planning to use native Javascript rather than jQuery can also anyone share their thoughts/opinion what are the things I should consider when using native Javascript?10 -
I need help.
Since few days I've been thinking to go for cross platform app development. I've heard some names like Xamarin, Flutter & React Native. But I'm confused in choosing one of them. Below are few things I've read about them.
Xamarin is more like native, but It needs more effort to make it cross platform.
Flutter is still in beta, but Its backed by google, So it can be future. + it has performance issues and it lacks many important libs.
React native uses Javascript. and It's kinda less native.
So, I'm confused to choose in of them. I need to choose the one with many libraries and is good at performance, and it must have less effort for making it for another platform.10 -
Now that you can make native apps in javascript for all platforms, is there any use for learning native development? Why not just learn a flavor of javascript and launch on all platforms?1
-
😢... Built a mobile app with React Native, the app implements Navigator api in JS to get coordinates. It works perfectly on 6.0 and below, but fails on 7.0 to be specific, Nokia 2 (it returns the same coordinates regardless of the location). How to go about this? What other library can I use to get coordinates?
PS: I have checked the permissions and they are set. -

Hey!
Would you recommend React Native, or Electron for a not really experienced programmer?
I am just starting with JavaScript, and these two tools are the most fascinating to me. :)
I have been learning C# in school, but mostly had to teach myself in the past year.
Anyway, thank you, if you answer, it is really nice on devRant, and it's my first developer community to be part of! :D
Sorry for the broken english - not my primary language.7 -
Hi all,
This isn't a rant but I'm after some advice. I'd like to learn React Native to start building mobile apps. I've never used React and to be honest, my JavaScript skills are a bit jQuery (if you get what I mean!).
Shall I jump into RN or learn ES5/6 and React first?2 -
The moment when you are desperate enough to integrate forceUpdate into production code.
Also I like how apollo-client acts like enterprise grade when they do all the heavy crap in the UI thread.3 -
I ❤ Swift and Xcode. However, tempted to learn React Native. Just so that I can put my apps on both the App Stores. Also ability to get more projects. What do you think? Is it worth learning? Thank you for the feedback in advance!😀1

Does anyone here have experience with Kotlin?
I'm 100% JavaScript/web development for the moment but I consider trying to write some native Android apps earlier or later and heard some good things about Kotlin (language developed by the guys from IntelliJ afaik), which is supported natively by Android.
Soooo, how does it hold up? -
NPM version : 10

react-native link
npm install
react-native run-android
REINSTALLING
MAKING A NEW PROJECT
Details :
Its documentation says add import com.reactlibrary.RNReatNativeGetMusicFilesPackage; but when automatically linking , it adds com.cinder72.musicfiles.RNReactNativeGetMusicFilesPackage;
Manually it is showing com.reactlibrary.RNReatN... is not found.
Automatically everything is working fine.
Error :
In the react-native-get-music-files/index.js

}
}
export default MusicFiles;
It says RNReactNativeGetMusic files is undefined.
I tried console log NATIVEMODULES and it shows nothing as RNReactNativeGetMusic or anything similar.2 -
One side effect of learning React Native for Android is JavaScript and Java start to look the same...
The only way to tell at a glance is the Java annotations...
