Fuxk yeah! My code works! It's 2AM, I'm happy and there's no one around, so I wrote a poem :-P
What was once impossible,
Is now close to completion,
Thanks to my debug statements,
Which now await their deletion.28 -
My biggest dev blunder. I haven't told a single soul about this, until now.
👻👻👻👻👻👻
So, I was working as a full stack dev at a small consulting company. By this time I had about 3 years of experience and started to get pretty comfortable with my tools and the systems I worked with.
I was the person in charge of a system dealing with interactions between people in different roles. Some of this data could be sensitive in nature and users had a legal right to have data permanently removed from our system. In this case it meant remoting into the production database server and manually issuing DELETE statements against the db. Ugh.
As soon as my brain finishes processing the request to venture into that binary minefield and perform rocket surgery on that cursed database my sympathetic nervous system goes into high alert, palms sweaty. Mom's spaghetti.
Alright. Let's do this the safe way. I write the statements needed and do a test run on my machine. Works like a charm 😎
Time to get this over with. I remote into the server. I paste the code into Microsoft SQL Server Management Studio. I read through the code again and again and again. It's solid. I hit run.
....
Wait. I ran it?
....
With the IDs from my local run?
...
I stare at the confirmation message: "Nice job dude, you just deleted some stuff. Cool. See ya. - Your old pal SQL Server".
What did I just delete? What ramifications will this have? Am I sweating? My life is over. Fuck! Think, think, think.
You're a professional. Handle it like one, goddammit.
I think about doing a rollback but the server dudes are even more incompetent than me and we'd lose all the transactions that occurred after my little slip. No, that won't fly.
I do the only sensible thing: I run the statements again with the correct IDs, disconnect my remote session, and BOTTLE THAT SHIT UP FOREVER.
I tell no one. The next few days I await some kind of bug report or maybe a SWAT team. Days pass. Nothing. My anxiety slowly dissipates. That fateful day fades into oblivion and I feel confident my secret will die with me. Cool ¯\_(ツ)_/¯12 -
At my old company one of my colleagues introduced async / await into our csharp code. He created interfaces and showed us a great structuring of his code. Sadly a few weeks later he left the company, because of personal reasons and a bug appeared in his written service. Our senior developer took the issue and complained for like 1 week. That you can't find anything, that interfaces are useless, that async / await is slow and sucks and that we should stop trying to bring new structures into the code base and do things the old way. In the end he deleted all the great things that my colleague introduced and wrote bad and smelly code.9

Manager: You can’t define an async function without using await.
Dev: Yes you can.
Manager: Well you shouldn’t, there’s no point!
Dev: Yes there is. It can turn blocking synchronous logic into work performed concurrently. In this case the perform—
Manager: It’s called async *await*. Async *AWAIT*! Did you hear the two parts to that? You shouldn’t ever have one without the other. THEY GO TOGETHER. Worrying about concurrency is for people who use callbacks which just goes to show how out of date your skills are. I’m reading a book on javascript and there are so many advanced techniques out there that I haven’t even seen you use ONCE!
Dev: …
*I looked at the book he’s reading, it’s from the < ES6 era… no wonder he doesn’t see me using any of those archaic patterns/hacks/workarounds…*13 -
Hi everyone, I'm new here but I liked the posts so I thought I'd chip in. Here's a picture of my home office.
I'm currently brushing up on SQL and Java in my internship while I await graduation at the end of the year. Java>C# IMO. C++ is my first love but nobody wants to hire for it anymore.
To everyone who's worked in Java, Eclipse or Intellij IDEA and why? (I mostly use Eclipse because the internship requires it).
I hope to have fun here, so please give me a warm welcome or a rant.22 -

Not to say anyone here is right or wrong about this, but I just do t get the whole privacy paranoia. Yes, I get that our rights are being violated. Yes I know I need to be aware and concerned.
People use specials rims, VPN software, etc... The bottom line is every keystroke, SMS, voice call, search text, historical reference... every piece of digital communication is recorded (At least in the US).
The sad reality is I can be as angry as I want, but unless I forego using tech or leaving the house, there is nothing I can do about it.
I await your comments, both positive and negative.53 -
Oh man. Mine are the REASON why people dislike PHP.
Biggest Concern: Intranet application for 3 staff members that allows them to set the admin data for an application that our userbase utilizes. Everything was fucking horrible, 300+ php files of spaghetti that did not escape user input, did not handle proper redirects, bad algo big O shit and then some. My pain point? I was testing some functionality when upon clicking 3 random check boxes you would get an error message that reads something like this "hi <SENSITIVE USERNAME DATA> you are attempting to use <SERVER IP ADDRESS> using <PASSWORD> but something went wrong! Call <OLD DEVELOPER's PHONE NUMBER> to provide him this <ERROR CODE>"
I panicked, closed that shit and rewrote it in an afternoon, that fucking retard had a tendency to use over 400 files of php for the simplest of fucking things.
Another one, that still baffles me and the other dev (an employee that has been there since the dawn of time) we have this massive application that we just can't rewrite due to time constraints. there is one file with (shit you not) a php include function that when you reach the file it is including it is just......a php closing tag. Removing it breaks down the application. This one is over 6000 files (I know) and we cannot understand what in the love of Lerdorf and baby Torvalds is happening.
From a previous job we had this massive in-house Javascript "framework" for ajax shit that for whatever reason unknown to me had a bunch of function and object names prefixed with "hotDog<rest of the function name>", this was used by two applications. One still in classic ASP and the other in php version 4.something
Legacy apps written in Apache Velocity, which in itself is not that bad, but I, even as a PHP developer, do not EVER mix views with logic. I like my shit separated AF thank you very much.
A large mobile application that interfaced with fucking everything via webviews. Shit was absolutley fucking disgusting, and I felt we were cheating our users.
A rails app with 1000 controller methods.
An express app with 1000 router methods with callbacks instead of async await even though async await was already a thing.
ultraFuckingLarge Delphi project with really no consideration for best practices. I, to this day enjoy Object Pascal, but the way in which people do delphi can scare me.
ASP.NET Application in wich there seemed to be a large portion of bolted in self made ioc framework from the lead dev, absolute shitfest, homie refused to use an actual ioc framework for it, they did pay the price after I left.
My own projects when I have to maintain them.9 -
JavaScript Motherfucking Asynchronous Bullshit.
I get it, for quite some stuff, async is very, very useful. But why on fucking earth do so goddamn many functions NEED this (and those callback functions) and can't do without?!
If there would be good and nicely understandable await documentation that actually fucking works, I'd be so happy.
I've currently got .then after .then after motherfucking then and its irritating me to no end as it, in this context, shouldn't even be necessary. This thing I'm writing doesn't give a fuck if something takes a few milliseconds before the rest of the program can continue!!
Fuck asynchronous programming in JavaScript for goddamn everything.
(I do love JavaScript!)27 -
First rant: but I'm so triggered and everyone needs a break from all the EU and PC rants.
It's time to defend JavaScript. That's right, the best frikin language in the universe.
Features:
incredible async code (await/async)
universal support on almost everything connected to the internet
runs on almost all platforms including natively
dynamically interpreted but also internally compiled (like Perl)
gave birth to JSON (you're welcome ppl who remember that the X in AJAX stood for XML)
All these people ranting about JS don't understand that JS isn't frikin magic. It does what it needs to do well.
If you're using it for compute-heavy machine learning, or to maintain a 100k LOC project without Typescript, then why'd you shoot yourself in the foot?
As a proud JS developer I gotta scroll through all these posts gushing over the other languages. Why does nobody rant about using Python for bitcoin mining or Erlang to create a media player?
Cuz if you use the wrong tool for the right job, it's of course gonna blow up in your face.
For example, there was a post claiming JS developers were "scared" of multithreading and only stick in their comfort zone. Like WTF when NodeJS came out everything was multithreaded. It took some brave developers to step out of the comfort zone to embrace the event loop.
For a web app, things like PHP and Node should only be doing light transforms between the database information and HTML anyways. You get one thread to handle the server because you're keeping other threads open to interface with databases and the filesystem. The Nexus.js dev ranting on all us JS devs and doesn't realize that nobody's actual web server is CPU bound because of writing HTML bodies, thats why we only use 1 thread. We use other worker threads to do the heavy lifting (yes there is a C++ bridge look it up)
Anyways TL;DR plz respect JS developers we're people too. ES7 is magic and please don't shit on ES3 or we'll start shitting on the Python 2-3 conversion (need to maintain an outdated binary just cuz people leave out ()'s in their print statements)
Or at least agree that VB.NET is an abomination and insult to the beauty that is TI-84 BASIC13 -

I've been using microsoft dev stack for as long as i remember. Since I picked up C#/.NET in 2002 I haven't looked back. I got spoiled by things like type safety, generics, LINQ and its functional twist on C#, await/async, and Visual Studio, the best IDE one could ask for.
Over the past few years though, I've seen the rise of many competing open source stacks that get many things right, e.g. command line tooling, package management, CI, CD, containerization, and Linux friendliness. In general many of those frameworks are more Mac friendly than Windows. Microsoft started sobering up to this fact and started open sourcing its frameworks and tools, and generally being more Mac/Linux friendly, but I think that, first, it's a bit too late, and second, it's not mature yet; not even comparable to what you get on VS + Windows.
More recently I switched jobs and I'm mainly using Mac, Python, and some Java. I've also used node in a couple of small projects. My feeling: even though I may be resisting change, I genuinely feel that C# is a better designed language than Java, and I feel that static type languages are far superior to dynamic ones, especially on large projects with large number of developers. I get that dynamic languages gives you a productivity boost, and they make you feel liberated, but most of the time I feel that this productivity is lost when you have to compensate for type safety with more unit tests that would not be necessary in a static type language, also you tend to get subtle bugs that are only manifested at runtime.
So I'm really torn: enjoy world class development platform and language, but sacrifice large ecosystem of open source tools and practices that get the devops culture; or be content with less polished frameworks/languages but much larger community that gets how apps should be built, deployed, monitored, etc.
Damn you Microsoft for coming late to the open source party.11 -
Ooh, look! Node got async/await!
Ooh, look! I can lint shell scripts with shellcheck!
Ooh, look! Webpack 2 has been released!
Ooh, look! I can switch over from npm to yarn!

I fucking hate chained methods. Ok, not all of them. Query things like array.where.first... that stuff is ok.
Specially if it's part of the std lib of a lang, which would be probably written by a very competent coder and under scrutiny.
But if you're not that person, chances are you'll produce VASTLY inferior code.
I'm talking about things like:
expect(n).to.be(x).and.not(y)
And the reason I don't like it is because it's all fine and dandy at first.
But once you get to the corner cases, jesus christ, prepare to read some docpages.
You end up reading their entire fucking docs (which are suboptimal sometimes) trying to figure if this fucking dsl can do what you need.
Then you give up and ask in a github issue. And the dev first condescends you and then tells you that the beautiful eden of code he created doesn't let you do what you want.
The corner cases usually involve nesting or some very specific condition, albeit reasonable.
This kind of design is usually present in testing or validation js libraries. And I hate all of those for it.
If you want a modern js testing lib that doesn't suck ass, check avajs. It's as simple as testing should be.
No magic globals, no chaining, zero config. Fuck globals forced by libs.
But my favorite thing about it that is I can put a breakpoint wherever the fuck I want and the debugger stops right fucking there.
Code is basically lines of statements, that's it, and by overusing chaining, by encouraging the grouping of dozens of statements into one, you are preventing me from controlling these statements on MY code.
As an end dev, I only expect complexity increases to come from the problems themselves rather than from needlessly "beautified" apis.
When people create their own shitty dsl, an image comes to my mind of an incoherent rambling man that likes poetry a lot and creates his own martial art, which looks pretty but will get your ass kicked against the most basic styles of fighting.
I fucking hate esoteric code.
Even if I had to execute a list of functions, I'd rather send them in an array instead of being able to chain them because:
a) tree shaking would spare from all the functions i didn't import
b) that's what fucking arrays are for, to contain several things.
This bad style of coding is a result of how low the barrier to code in higher level langs are.
As a language or library gets easier to use you might think that's a positive thing. But at the same time it breeds laziness.
Js has such a low learning curve that it attacts the wrong kind of devs, the lazy, the uninspired, the medium.com reader, the "i just care about my paycheck" ones.
Someone might think that by bashing bad js devs I'm trying to elevate myself.
That'd be extremely stupid. That's like beating a retarded blind man in a game and then saying "look, I'm way better than this retarded blind man".
I'm not on a risky point of view, just take a stroll down npmjs.com. That place is a landfill. Not really npm's fault, in fact their search algorithm is good.
It's just the community.
Every lang has a ratio of competence. Of competent to incompetent devs.
You have the lang devs and most intelligent lib devs at the top. At the bottom you have the bottom.
Well js has a horrible ratio. I wouldn't be shocked to find out that most js devs still consider using import or await the future.
You could say that js improved a lot, that it was way worse beforr. But I hate chaining now, and i hated back then!
On top of this, you have these blog web companies, sucking the "js tutorial" business tit dry, pumping out the most obscenely unprofessional and bar lowering tutorials you can imagine, further capping the average intelligence of most js devs.
And abusing SEO while they're at it, littering the entire web with copy paste content.2 -

Wanna hear a story? The consultancy firm I work for has been hired to work on a WPF project for a big Fashion Industry giant.
We are talking of their most important project yet, the ones the "buyers" use to order them their products globally, for each of the retail stores this Fashion giant has around the world. Do you want to know what I found? Wel, come my sweet summer child.
DB: not even a single foreign key. Impossibile to understand without any priopr working experience on the application. Six "quantity" tables to keep aligned with values that will dictate the quantities to be sent to production (we are talking SKUs here: shoes, bags..)
BE: autogenerated controllers using T4 templates. Inputs directly serialized in headers. Async logging (i.e. await Logger.Error(ex)). Entities returned as response to the front end, no DTOs whatsoever.
WPF: riddled with code behind and third party components (dev express) and Business Logic that should belong to the Business Layer. No real api client, just a highly customized "Rest Helper". No error reporting or dealing with exceptions. Multiple endpoints call to get data that would be combined into one single model which happens to be the one needed by the UI. No save function: a timer checks the components for changes and autosaves them every x seconds. Saving for the most critical part occurring when switching cells or rows, often resulting in race conditions at DB level.
What do you think of this piece of shit?6 -

Update on my Facebook and Booking.com interviews. I had them back to back today.
Even before I start, I accept and admit that I am a hypocrite. I hate Amazon yet order stuff from there. I hate Microsoft yet use their products. I hate Facebook yet went ahead to interview with them.
I fucking hate myself for compromising my ethics, values, and integrity. I had promised myself that even if I work for any major shit company, I'd never go with Facebook. Here I am after many years. Not an excuse, but I am doing it because I see it as an entry point into the UK. That's all.
Community's hate towards me is justified and I'd accept the discrimination from this community because this place is my digital home and you all are my family. Infact first thing I told mom was, dR boys are gonna disown me when they get to know about this.
Anyway, coming to the update part.
I had applied leave at work from last Friday. 4 days of leave earned me 10 days off (including weekends and 2 days of Diwali company holiday).
Last Thursday I got to know that Facebook has scheduled their interview today (Friday). I spent insane amount of time preparing. Approximately 8 hours everyday including weekend. I added nearly 40+ hours preparing for it in last 7 days, because I had to get in. Failure isn't an option now.
I sacrifice my family time, preparing for the interview.
I sacrifice Diwali break, sitting in front of the screen and studying.
I sacrifice my only vacation of 2021, doing mock interviews as late as 11.30 PM.
I sacrifice my free time and enjoyment, stressing over what could happen.
I was prepared like perfect for screening stage.
Interview 1: this guy comes and ask 'what is the best compliment you have got as a PM?' and 'Why do you want to quit the current company?'
He wasn't supposed to ask those as per Facebook's policy and interview stage.
Then he gave me a shit problem to solve and rejected my approach and wanted it his was. I tried to follow him and made sure I was able to convince with the reasoning but he kept pushing me back. He kept putting me down. Did not listen to me or what I had to convey or what was expected as an answer. He had certain output in his mind and wanted me to come up with it as an answer.
For the uninitiated: Facebook gives ton of preparation material and tells upfront the kind of questions they'll ask they just focus on few things. Moreover, in Product interviews, there isn't right or wrong answer.
Anyway, this guy started making funny expressions which put my morale down and I stood my ground with losing my cool. I managed to get all my answers right and the key points the look into a candidate. It went decent. Yet the interviewers attitude was something I did not like.
Interview 2: the lady was really kind and warm. Very accommodating and easy person to deal with. It went amazingly well.
I have two observations I want to share with you all.
1. I hate what Facebook does. Lizardberg is awful human being. But I absolutely liked HOW they are doing things, at least from an interview stand point. They even had mock sessions by their PMs and upfront told how to prepare and how to answer.
2. While it seems to be a 5 star experience, I found them to function mechanically. No small talk, no human connection (ironic to their mission), no conversational flow of the interview (again something that they kept saying a zillion times in all their material). They came, formally introduced themselves, and had a checklist kind of attitude, and left.
I now await for the feedback.
In the next hour, I had Booking.com first round.
Amazing people. Warm friendly experience. Treated me as a human. Heard me. Made me feel part of the conversation rather than someone just being judged.
It went 1000x better than Facebook.
I await the feedback from them as well.
I don't know what's gonna happen but one thing for sure, the kind of expectations Facebook set for their interviews, was nowhere close to the reality. It was awful.
180° was for Booking.com
Guess the saying stands true, expectations always lead to disappointment.
Finally I feel de-stressed and my Diwali vacation starts AFTER Diwali ended. Or rather just a regular weekend.
2021 has been terribly awful year for me. Hope this shitty year ends soon.36 -

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 -
PhD saga:
The applications have closed and yours truly shall await the results, which could come anytime in January or February.
And so I wait. I hate this limbo since there is nothing for me to do to impact the outcome. What's worse is that I am absolutely unmotivated to do anything else. Since this project is literally my dream, and despite how I'm trying to mentally prepare myself in case I don't get in, there's just something in my brain that goes like "nah. I just want this shiney thing. Just this and nothing else". So I don't even know what to do with myself.
*Sigh*5 -
I was just chatting with my dad. He used to be mostly a C# dev but changed jobs and is now doing mostly Java. He says he likes it better.... Because it doesn't have lambdas/anonymous functions.
Uh.... Java was the first and only language where you can define interface implementations in-line (aka a whole bunch of functions)...
And 1.8 supports lambdas for Interfaces that have a single function...
I bet he'll hate JS... Where functions are can be passed around like objects, ES6 now supports lambdas and await, async... and anonymous functions (apparently they're called arrow functions?)9 -
TL;DR C# has changed quite a bit since the last time I used it.
So I'm working on a personal project, it's written in C#. When I needed to run a task on a separate thread. It has been years since the last time I worked with C#, so I googled it.
Me: "Async? Await? Task? This looks pretty fucking useful. When was this added?"
*Googles a bit*

Im now working as a fulltime dev for 3 years. I do programming since im 9 and now that I collected some experience, I have to to say, its horrible. Seriously. What the fuck is wrong with german internship companys? Letting me do 3 years of FUCKING CRYSTAL REPORTS. IN A DEVELOPMENT TEAM THAT CONSISTS OF A TEAM LEAD THAT ACTUALLY HAS TO LEARN SHIT LIKE PROPER OOP AND ASYNC/AWAIT FROM ME. THEY EVEN ASKED ME IF I CAN DROP OF MY HOBBY PROJECTS TO WORK ON SAMPLES THAT THEY CAN LEARN FROM! NO! FUCK! JUST BECAUSE THESE DOUCHBAGS ARE TOO LAZY TO FUCKING LEARN TECHNOLOGY THEY SHOULD BE PASSIONATE ABOUT IN THEIR FREE TIME, IM NOT MAKING IT MY JOB TO FREAKING SHOW THEM THAT HAVING A STATIC CLASS CONTAINING ALL MODELS EVER EXISTED IN THE APP IS A BAD THING! SERIOUSLY, THERES ONLY ONE INSTANCE OF EVERY MODEL WE HAVE! AND THEN THEY BLAME SQL SERVER FOR RACE CONDITIONS WHEN TRYING ASYNC!!!! WHAT THE FUCK!! AND STILL, IF I TELL THEM WHATS WRONG, IM AN IDIOT BECAUSE IM A JUNIOR! Please tell me that i didnt waste 10 years of my life dedicating to such bullshit. Will that change? Is it company specific?9

I need to delay execution of code in a for loop, how do I do that?
PHP: Sleep(3000)
Javascript:
const waitFor = (ms) => new Promise(r => setTimeout(r, ms))
const asyncForEach = (array, callback) => {
for (let index = 0; index < array.length; index++) {
await callback(array[index], index, array)
}
}
const start = async () => {
await asyncForEach([1, 2, 3], async (num) => {
await waitFor(50)
console.log(num)
})
console.log('Done')
}
start()

So, I've had a personal project going for a couple of years now. It's one of those "I think this could be the billion-dollar idea" things. But I suffer from the typical "it's not PERFECT, so let's start again!" mentality, and the "hmm, I'm not sure I like that technology choice, so let's start again!" mentality.
Or, at least, I DID until 3-4 months ago.
I made the decision that I was going to charge ahead with it even if I started having second thoughts along the way. But, at the same time, I made the decision that I was going to rely on as little external technology as possible. Simplicity was going to be the key guiding light and if I couldn't truly justify bringing a given technology into the mix, it'd stay out.
That means that when I built the front end, I would go with plain HTML/CSS/JS... you know, just like I did 20+ years ago... and when I built the back end, I'd minimize the libraries I used as much as possible (though I allowed myself a bit more flexibility on the back end because that seems to be where there's less issues generally). Similarly, any choice I made I wanted to have little to no additional tooling required.
So, given this is a webapp with a Node back-end, I had some decisions to make.
On the back end, I decided to go with Express. Previously, I had written all the server code myself from "first principles", so I effectively built my own version of Express in other words. And you know what? It worked fine! It wasn't particularly hard, the code wasn't especially bad, and it worked. So, I considered re-using that code from the previous iteration, but I ultimately decided that Express brings enough value - more specifically all the middleware available for it - to justify going with it. I also stuck with NeDB for my data storage needs since that was aces all along (though I did switch to nedb-promises instead of writing my own async/await wrapper around it as I had previously done).
What I DIDN'T do though is go with TypeScript. In previous versions, I had. And, hey, it worked fine. TS of course brings some value, but having to have a compile step in it goes against my "as little additional tooling as possible" mantra, and the value it brings I find to be dubious when there's just one developer. As it stands, my "tooling" amounts to a few very simple JS scripts run with NPM. It's very simple, and that was my big goal: simplicity.
On the front end, I of course had to choose a framework first. React is fine, Angular is horrid, Vue, Svelte, others are okay. But I didn't want to bother with any of that because I dislike the level of abstraction they bring. But I also didn't want to be building my own widget library. I've done that before and it takes a lot of time and effort to do it well. So, after looking at many different options, I settled on Webix. I'm a fan of that library because it has a JS-centric approach. There's no JSX-like intermediate format, no build step involved, it's just straight, simple JS, and it's powerful and looks pretty good. Perfect for my needs. For one specific capability I did allow myself to bring in AnimeJS and ThreeJS. That's it though, no other dependencies (well, at first, I was using Axios because it was comfortable, but I've since migrated to plain old fetch). And no Webpack, no bundling at all, in fact. I dynamically load resources, which effectively is code-splitting, and I have some NPM scripts to do minification for a production build, but otherwise the code that runs in the browser is what I actually wrote, unlike using a framework.
So, what's the point of this whole rant?
The point is that I've made more progress in these last few months than I did the previous several years, and the experience has been SO much better!
All the tools and dependencies we tend to use these days, by and large, I think get in the way. Oh, to be sure, they have their own benefits, I'm not denying that... but I'm not at all convinced those benefits outweighs the time lost configuring this tool or that, fixing breakages caused by dependency updates, dealing with obtuse errors spit out by code I didn't write, going from the code in the browser to the actual source code to get anywhere when debugging, parsing crappy documentation, and just generally having the project be so much more complex and difficult to reason about. It's cognitive overload.
I've been doing this professionaly for a LONG time, I've seen so many fads come and go. The one thing I think we've lost along the way is the idea that simplicity leads to the best outcomes, and simplicity doesn't automatically mean you write less code, doesn't mean you cede responsibility for various things to third parties. Those things aren't automatically bad, but they CAN be, and I think more than we realize. We get wrapped up in "what everyone else is doing", we don't stop to question the "best practices", we just blindly follow.
I'm done with that, and my project is better for it! -
People around me and clients are increasingly saying i am a genius, because i show them an app i made in react-native or some crappy site i set up in a week as POC.
While im quite noobish still, i barely read publications out of interests, and most of the time i just put in async/await somewhere just to see if it makes the promise work or not, because i dont understand promises fully, and I think in general i just accomplished very little in the 5 years I have been programming
It is really putting pressure on my impostor syndrome, even more when i talk with my peers who can tell who was the driving force behind ES6 :/9 -
I don't want to ever hear that you're proficient in JavaScript if you put a callback function call inside of an async function right after using the await command.
All you manage to do in the end was make a simple function that gets data to populate a dropdown menu into something that is absolutely more awful to look at than the worst callback hell possible.
Refactoring this code base has really questioned my sanity and how much I'm willing to spend on alcohol.4 -
I just released my first NPM package that is actually functional and used in a private project (https://npmjs.com/package/@lbfalvy/...) and I have to say, the quality of debug tooling for Node is abysmal. I spent 4 hours just on Webpack's "Field browser doesn't contain a valid alias configuration" error which simply means "package not found", and then getting Rollup to output a working compiled javascript _and_ a d.ts was its own day-long ordeal.4

Just got started with nodejs and I never thought I’d have to use async/await this early. Concurrency seemed like a far fetched thing. Feeling like a boss😎1
-
JavaScript is new the PHP.
Reading a stackoverflow question about async functions and await-usage, and lot of well-intended answers show no understanding of the concept. Some fail to understand that the scope is about promises. They don't know that, yes, *every* async function *always* returns a Promise and that within an async function it's synctically the same to do either `return x` or `Promise.resolve(x)` or `return new Promise((resolve) => {resolve(x)}), and they fail to realize what await does or doesn't do and are oblivious about how awaiting at certain stages can have huge performance impact when compared to either Promise.all or Bluebird.map.
Grasping promises is hard in the beginning, I get that. But please don't share your lack of understanding as fact. -
My Boss Abuses me, should I leave my job?
I overheard this tidbit on a bus recently. Okay I'm lying. But in the great spans of
time I've spent reading "dear annie" type articles, many involving how often my meth head step dads beat me while growing up, or in turn how often *I* beat me (oh yeah)..I've come across this in one form another, this, and other dumbfuck questions from the stuttering meek and halfhearted.
They say there are no dumb questions. Well, like that guy who smoked too much weed and
asked "what is the sound of one hand clapping?" (fap fap fap), there are in fact dumb questions.The world is overflowing with them, like a clogged shitter full of tacobell and glitter covered brown gutter wisdom. And it smells like roses, if roses smelled like shit.
Questions like "How do I make sure my cats don't feel lonely once I have my first child?"
I don't know, they're fucking cats. Did you even google this before asking?
Or
"How to make spaghetti?"
Really, is this question written by a bot?
"What is the best javascript framework in year x?"
All of them and none of them. Welcome to hell.
"Whats your favorite color?"
My answer: I'm not five years old any more. And obviously you are. Why are you on this site instead of eating crayons at daycare?
Yes indeed, this and many more dumbfuck questions await you and can be found on the preeminent quora, amongst other sites.
A place, which censored an eminently reasonable answer of mine (I was totally not being a shithead btw).
I responded in kind by removing a whole mess of long form answers of mine.
What I have learned from the experience is this: Humanity is greatly comprised of many people who, having no brains to speak of, wander aimlessly like beasts of the field, glass eyed and slack jawed, in search of a savior. But their savior came a long time ago, once, and many times before. An engineer, or programmer, or perhaps in another reincarnation a guy parting a sea of koolaid after the local ruler swindled his peeps out of another payment for moving some heavy ass stone blocks, but I digress.
And in response to peoples worries, anxieties, everyday problems and concerns, every one of these would be wiseman, every one of these saviors, leaders, and great men spoke these magic words which resonate now down through the ages like the voice of reason and providence:
"Read the FUCKING manual."
"And don't bother me again asshole." (well this last bit is all me, but I'm sure others said it too.)2 -

I had the idea that part of the problem of NN and ML research is we all use the same standard loss and nonlinear functions. In theory most NN architectures are universal aproximators. But theres a big gap between symbolic and numeric computation.
But some of our bigger leaps in improvement weren't just from new architectures, but entire new approaches to how data is transformed, and how we calculate loss, for example KL divergence.
And it occured to me all we really need is training/test/validation data and with the right approach we can let the system discover the architecture (been done before), but also the nonlinear and loss functions itself, and see what pops out the other side as a result.
If a network can instrument its own code as it were, maybe it'd find new and useful nonlinear functions and losses. Networks wouldn't just specificy a conv layer here, or a maxpool there, but derive implementations of these all on their own.
More importantly with a little pruning, we could even use successful examples for bootstrapping smaller more efficient algorithms, all within the graph itself, and use genetic algorithms to mix and match nodes at training time to discover what works or doesn't, or do training, testing, and validation in batches, to anneal a network in the correct direction.
By generating variations of successful nodes and graphs, and using substitution, we can use comparison to minimize error (for some measure of error over accuracy and precision), and select the best graph variations, without strictly having to do much point mutation within any given node, minimizing deleterious effects, sort of like how gene expression leads to unexpected but fitness-improving results for an entire organism, while point-mutations typically cause disease.
It might seem like this wouldn't work out the gate, just on the basis of intuition, but I think the benefit of working through node substitutions or entire subgraph substitution, is that we can check test/validation loss before training is even complete.
If we train a network to specify a known loss, we can even have that evaluate the networks themselves, and run variations on our network loss node to find better losses during training time, and at some point let nodes refer to these same loss calculation graphs, within themselves, switching between them dynamically..via variation and substitution.
I could even invision probabilistic lists of jump addresses, or mappings of value ranges to jump addresses, or having await() style opcodes on some nodes that upon being encountered, queue-up ticks from upstream nodes whose calculations the await()ed node relies on, to do things like emergent convolution.
I've written all the classes and started on the interpreter itself, just a few things that need fleshed out now.
Heres my shitty little partial sketch of the opcodes and ideas.
https://pastebin.com/5yDTaApS
I think I'll teach it to do convolution, color recognition, maybe try mnist, or teach it step by step how to do sequence masking and prediction, dunno yet.6 -
I'm still using .then().catch() instead of the async await.
So, first of all, Fuck you for calling it a STANDARD now. its nowhere near to be called standard. You wanna get some data from an API? Wanna call it using axios or fetch? What if the server is down? what if there's an error that you don't even know existed? Where do I get that kinda error in async await? try-catch? no thanks :| I'm good -_-8 -
Til that Node 10 has `for await ... in`. Basically looping async iterators. This changes everything!5

I got the Aero15. Had to send it in because ctrl+alt+shift+s (IntelliJ Preference menu) and some others critical shortcuts weren't working. Got a reply a week later.
"Thank you for using our service. The explained fault isn't actually a fault. If you want to use that button combination simply remap the FN key. Mind you this will disable any FN key combinations."

"What about all the other combinations?"

"Ok we returned it to the technicians who will do their best to repair it."

So if you’re awaiting a promise and the async function returning the promise calls another async function and doesn’t await it could this counterintuitively cause the whole thing to freeZe ?14

I can't get over the fact that my company downgraded the project from Elixir Phoenix to nodejs express.
I asked them why, they told me, the elixir is difficult and blablabla. In my resume, I did mention I have the experience for 2 and a half years (phoenix one year) , I can do that. and previously the senior here used elixir for scalibility , etc. Personally, the system he built weren't bad at all.
now in nodejs , with the async await promise shit.
but 'we prefer old tech' they say . old is gold they say .
Wait nodejs isn't old. To me elixir is like Ruby and Erlang had sex and gave birth to it and named it elixir.5 -

i come from a very closely knit family and i kinda like it. i am in close proximity to my parents, they are growing old so i do a lot of home chores. meanwhile a lot relatives and dad's business friends live nearby , and the whole area around my home feels like a place of known people. my free time goes with 5-6 friends , who again live nearby, or with gym buddies. this is a nice life, which could further expand with a wife and my kids in future .
at the same time, i have seen the "work" life. my office is in a different state, 90% of people there are people like me who would be renting a home nearby and living alone/with strangers. their main "family"(well pseudo-family) will be their coworkers, and that's also not a bad thing.
in the workplace the reasons to be happy will be a lot (as parties or celebrations will occur on multiple birthdays/ company growths and other achievements) , and so will be the reasons to feel sad ( company failure, teammates leaving, missing family)
at the end of the day , when you are living an office life, you are a corporate rat running for the cheese you are never gonna (or , if you are a glass half full person, let's say that you are a "dedicated work professional giving your 100% to the company")
but here comes the dilemma : with AIs like chat gpt coming around and redefining nthe expectations from a software engineer, you will no longer be expected to be resourceful but rather how much of a corporate rat you can be. ( https://twitter.com/bajicdusko/...)
so 1) is it the only way forward for an upcoming engineer's lifestyle? to be like a soldier for their company , while their family and friends await for their long return? 2) if yes, what is the positi8 aspsct we can take away from this?
PS : what a stupid profession those AI/ML guys work in. they put out their minds together to make a sword which is gonna cut the heads of s/w engineers, their own breed. not lawyers, not doctors, not even the fucking peons, but their own freaking brothers4 -
There's a special place in hell for JS people using `.then()` and `.catch()` instead of simply `await func()`.
Why have 5 lines of code with an await, when instead you can have 5 nested `.then` callbacks.
And yes I know there are some cases where async/await isn't applicable, but that's rather rare25 -
It's nice that more and more languages are introducing async/await syntax, but by the example of Rust in particular I'm starting to wonder why we don't instead introduce this syntax for monads in general?
We could have a keyword (say, `bind`) which unwraps a value from any monad provided that the return value of the function is wrapped in the same monad. The ? operator does something a little similar, and I'll be intrigued whether it can actually be implemented for monads other than Result and Option once GATs are stabilized. In particular in the case of Rust, it would be possible to create a reference counting monad for heap-bound management of objects derived from references.9 -

Vampire homegirl and I got into bit of a pickle last time we went out marauding around the City of the Dead. We collected payment for a hit on a merchant, but a large portion of the money was discounted, as unbeknown to us, there was a witness to our bloody crime.
Soon enough, we were being hunted down by a rival sect, encroaching on our territory. Their High Priest sent some dogs our way, and we felt right into their ambush, at a crossroads within the southern alleways. I took down three of those sons of bitches, with two crossbow bolts stuck on my back, before finally being knocked down by a shield slammed to my face.
Got both my fucking legs mauled with a flail and almost put out of commission. Luckily, my vampiric companion was there to save my skin. She fought a desperate duel against the last one of our foes left standing: an inquisitor, sent to either capture, or more likely, kill us both.
This fucker was tougher than any adversary either of us had ever fought against. Fully clad in silver armor, wearing an enchanted crimson cloak, her face hidden behind a terrifying iron mask. My companion stood her ground, but throughout the fight, she was constantly on the defensive, hesitant to close too much distance against the enemy.
Our foe launched one devilishly mighty blow, that my partner in crime fortunately managed to block. However, her blade was pulverized by the sheer weight of the inquisitor's strike, nearly shattering her ribcage. In a last ditch effort to survive the encounter, she lunged at her opponent with what remained of her sword, and stabbed the hunter right in her fucking eye, to then sink her fangs into the ecclesiastical bitch's neck.
Having temporarily incapacitated the inquisitor, we made our escape. My companion carried me back to our safehouse, where we would plan our next move... but our masters were one step ahead of us.
At our hideout, we were intercepted by them, at the behest of the Matriarch. We were to be smuggled out of the city inside a funeral carriage, to then be safely transported back to our sacred order's sanctuary.
Uppon arriving, we were confronted and reprimanded for our failures, past and present. I was forcefully separated from my esteemed nocturnal friend, as way our masters put it, our growing affections were cause for concern. Longing to be reunited, we schemed for weeks through our mutual acquaintances in the monastery, delivering small coded messages.
Through our cunning subterfuge, we finally managed to meet in an ancient grotto underneath a cedrus tree, on a hill overlooking the sanctuary. I was ready to plan a daring escape, but to my suprise, she had her mind made up to a wildly different course of action. We were to play by their rules -- go through with their dark cleansing rituals, meant to re-educate us before admitting us back into the order as fully-fledged acolytes.
And so, in the penumbra of that age-old grotto, a pact was made.
I am now riding south on a black stallion, falchion in hand, and a trail of witches' blood in my wake. I carry with me orders from the Matriarch herself: purify the nearby catacombs and prove my devotion to the utter blackness of our faith. Should I not return, my companion will be up next.
Failure is not an option. As I evade the twisted creatures that guard the entrance, and descend the staircase down into the tomb, I wonder what kind of horrors await me inside...

Over the last week I've slowly grown to fucking hate IMAP and SMTP. You'd think after so many years we'd have come up with better servers to manage email but no we still rely on fucking decades old protocols that can't even batch requests.
To make things worse I need to attach to IMAP through node and that has been a nightmare. All the libraries suck ass and even the ones tailored towards Gmail don't work for Gmail because Google decided one day to fucking out the header at the bottom of some emails and split into mimeparts. Also why the fuck is fetching email asynchronous? There's no point at all since we requests are processed line by line in IMAP, and if the library actually supported sending asynchronous requests it wouldn't require a new object to be created for each request and allow only a single listener.
Also callbacks are antiquated for a while and it pisses me off that node hasn't updated their libraries i.e. TLS to support async/await. I've taken to "return await new Promise" where the resolve of the promise is passed as the callback, which let's me go from callback to promise to async/await. If anyone has any other ideas I'm all ears otherwise I might just rewrite their TLS library altogether...
And this is just IMAP. I wish browsers supported TLS sockets because I can already see a server struggling with several endpoints and users, it would be much easier to open a connection from the client since the relationship is essentially:
Client [N] --- [1] Server [1] --- [1] IMAP
And to make the legs of that N : N which would fix a lot of issues, I would have to open a new IMAP connection for every client, which is cool cause it could be serverless, but horrifying because that's so inefficient.
Honestly we need a new, unifying email protocol with modern paradigms...8 -
Modern Web Developer

I am the very model of a modern web developer
I’m quite fluent with JavaScript; An HTML whisperer
My code is clean and elegant, I genuinely innovate
And even know my way around a Promise and async / await
I’m very well acquainted too with matters vector graphical
I understand why SVG coordinates seem magical
And even without Photoshop I elegantly can produce
A mockup or a logo in most any format that you choose
[Chorus]
A mockup or a logo in most any format that you choose
A mockup or a logo in most any format that you choose

I know the ins and outs of functional reactive programming
In short, in matters browser-based or Node.js if you prefer
I am the very model of a modern web developer
[Chorus]
He is the very model of a modern web developer
I know our mythic history, the humble start, the browser wars
I know why Douglas Crockford fought the battle over ES4
The World Wide Web Consortium and Ecma International
My knowledge of our legacy is truly supernatural
With LESS and SASS and CSS, designing for mobility
I’ll perfectly apply the right amount of specificity
From custom fonts and parallax to grid and flex and border-box
I know most every tip and trick both common and unorthodox
[Chorus]
He knows most every tip and trick both common and unorthodox
He knows most every tip and trick both common and unorthodox
He knows most every tip and trick both common and unorthodox
And when it comes to lazy loading, bundling up and splitting code
There’s nothing quite like Webpack, which of course is built on top of Node

[Chorus]
He is the very model of a modern web developer
When new frameworks and libraries emerge I must be ravenous
And gobble up the hot new thing, my appetite is bottomless
React and Vue and Angular, Immutable, RxJS
The list will be outdated long before I'm finished singing this
My pull requests rely on multitudinous utilities
To help me lint and test and build, a deluge of analyses
And every single day there are a hundred thousand more to learn
The web is going through an irresponsible amount of churn
[Chorus]
The web is going through an irresponsible amount of churn
The web is going through an irresponsible amount of churn
The web is going through an irresponsible amount of churn
This pace is agonizing! Code from yesterday is obsolete!
The speed of innovation is enough to knock me off my feet!

Isn't this (not my code) callback hell all over again? The 2. http call expects results from the 1. http call. I feel like this could be solved cleaner using async await/switchMap/etc. ... but not like this.13 -
I'll need to do a survey on how different frontend frameworks support asynchrony, both in data and component loading.
I have a very powerful lazy loading primitive for React (https://github.com/lbfalvy/... ), but it's a bit broken so I'm rewriting it into a stateful TS class (because it would have to allocate a lot to be immutable and fast) and a React shim. I'm considering adapting it to other frameworks that struggle with code splitting or async data, or perhaps - like react - only ship a built-in solution that requires unrelated business logic to acknowledge the frontend framework.
Are you happy with the workflow of using asynchronously loaded data in your frontend framework of choice?1 -
Originally I'm coming from Java , about 2 years ago, I switched Node with TypeScript and had a hard time getting accustomed to Promises. It was a big relief when I learned about async/await. Much cleaner code, no brainfuck anymore when thinking about how to handle stuff that requires multiple async values and so on.
Now I'm working on a clients project as a Java dev again. SOA, Spring Framework, Kafka and MongoDB, nothing too complicated... if they wouldn't use reactor to bring reactive functionalities to Java.
It feels like I'm back in Promise Hell...2 -
If anyone is good with dart (or) other single threaded programming languages, i have this small doubt about the inner workings of the event loop and such and i would like an explanation if possible.
If you're too lazy to goto the link:
1. I have a future returned from a http request.
2. a future.then is declared that prints the http result.
3. A separate while(true) loop is declared that runs forever that just prints natural numbers.
4. the while loop also has an await future.delay that waits for 1ms before continuing with the next iteration
My question :
1. There's only one thread so how does the http download code run WHILE my main loop is still executing.
2. my future.then event is not processed unless i await a future.delay separately for 1ms. returning control to the event loop ? i don't get it how does adding an event help it process a prior event? It's FIFO ?

Can anyone point me to some example of a .net project that doesn't scale because not using async await for IO?
I'm not sure how to measure impact of not doing this...3 -
So I'm new to NestJS, Node, etc. and I just noticed that the guy working on the API made every request call a different service class, instead of using a single service class. For example.
get() {
return await this.getObj.run()
}
post(myDto){
return await this.storeObj.run()
}
update(myDtoUpdate){
return await this.updateObj.run()
}
And I'm not sure why. He's also injecting the request into those classes, instead of passing the DTO to the method call. I mean, it's still injecting the data into it I guess, but it seems so roundabout. Something like this:
public constructor(
@Inject(REQUEST) private request: Request,
){}
I'm scared, but I'm not sure if it's just my own ignorance or a sixth sense telling me that this is gonna be a mess.
Have you seen APIs implemented this way? I can see the benefit of dividing the code into smaller classes, but it just seems overkill to me, specially when there's a big chance that code will be repeated (getting an entity by ID when updating it, for example).
I'm still in time to kill this with fire before a new monster is born though, so that's something.1 -
Hello chat, its been a long week with no progress, i have four problems right now.
1 node js repl cant recognize <> in js, and i cant find a fix for that anywhere on the internet, is there a way to convert html tags in js to smooth brackets code?
2 node js repl dosnt recognize codes like import react from react, and i have to do an async function load, and i dont know y or how to fix it.
3 i dont know how to write import exg.csv into an async function load, its usually something like “import react from react” to “async function load(){let react=await import (‘react’);}”, and i dont know how to do this.
4 i tried to install materials.ui using npm into a folder called materialsui in modules in node, it deleted all the other modules in module folder, installed, and then left the materialsui folder empty. I complained and i dont know how to get it to not do that.
5 how do i fix out of memory errors?8 -
I love and hate javascript. I set out to do a fully ajax/state driven form interface that operates with multiple interdependent data objects which all extend a base class.
React/Angular may have been a better call but I just didn't have time so I needed to rapid prototype in jquery /vanilla JS.
I'm in the midst of learning and refactoring all the ajax calls to promises and then to async/await, so it's a huge learning experience...
Meanwhile I've got to build objects to represent the data on the backend which is all legacy OScommerce/PHP
Hell of a ride. -
I know I sound stupid but I need help, I create a repo on GitHub using gh-api ```js
export async function createARepo({name,description,token}) {
const headers = {
"Authorization": `token ${token}`,
"Accept": "application/vnd.github.v3+json",
}
const {data} = await axios(
{
method: "POST",
url: "https://api.github.com/user/repos",
data: {name,description,auto_init: true},
headers
}
)
return data
// console.log(res)
}```
when I run this code it only creates an empty project with a readme but I also want to create a file with a .html extension of the project can anybody help me with how I do this?7 -
So I've been pondering for a while now: is async/await a load of bollocks, or am I just stupid?
I'm gradually coming to the conclusion that it's probably both.6 -
for some reason, the async/await C# keywords evoke the image of a child with ADHD running around in excitement shouting "async, async" and letting go of helium balloons in the air, while his father stands in a stiff brown suite and a mustach and every few seconds says calmly (but strictly): "await" .. just killing the excitement1

This is the story of how I spent 4h of my life trying to compile a simple node library written with es6 using babel 7.
My error was to use async/await. Previously babel wasn't that bad. A bit complicated and undocumented. But now is a pain in the ass as soon as you need something more than the prefix.
Don't use more time to make a compiler work than to write a library1 -
So I've been forced to work on a project for some time using JavaScript
Many parts of it must function synchronously and js has a lot of libs and otherwise that will spawn threads in threads
I'm horrified by the amateurish appearance of my code
Await this await that
Everything enclosed in something else and what is worse is the base node modules I'm using are ALL asynchronous! Were talking methods that one consistently has to wait on finishing like db reads !
Why is js so dumb ?26
