WASM was a mistake. I just wanted to learn C++ and have fast code on the web. Everyone praised it. No one mentioned that it would double or quadruple my development time. That it would cause me to curse repeatedly at the screen until I wanted to harm myself.
The problem was never C++, which was a respectable if long-winded language. No no no. The problem was the lack of support for 'objects' or 'arrays' as parameters or return types. Anything of any complexity lives on one giant Float32Array which must surely bring a look of disgust from every programmer on this muddy rock. That is, one single array variable that you re-use for EVERYTHING.
Have a color? Throw it on the array. 10 floats in an object? Push it on the array - and split off the two bools via dependency injection (why do I have 3-4 line function parameter lists?!). Have an image with 1,000,000 floats? Drop it in the array. Want to return an array? Provide a malloc ptr into the code and write to it, then read from that location in JS after running the function, modifying the array as a side effect.
My- hahaha, my web worker has two images it's working with, calculations for all the planets, sun and moon in the solar system, and bunch of other calculations I wanted offloaded from the main thread... they all live in ONE GIANT ARRAY. LMFAO.If I want to find an element? I have to know exactly where to look or else, good luck finding it among the millions of numbers on that thing.
And of course, if you work with these, you put them in loops. Then you can have the joys of off-by-one errors that not only result in bad results in the returned array, but inexplicable errors in which code you haven't even touched suddenly has bad values. I've had entire functions suddenly explode with random errors because I accidentally overwrote the wrong section of that float array. Not like, the variable the function was using was wrong. No. WASM acted like the function didn't even exist and it didn't know why. Because, somehow, the function ALSO lived on that Float32Array.
And because you're using WASM to be fast, you're typically trying to overwrite things that do O(N) operations or more. NO ONE is going to use this return a + b. One off functions just aren't worth programming in WASM. Worst of all, debugging this is often a matter of writing print and console.log statements everywhere, to try and 'eat' the whole array at once to find out what portion got corrupted or is broke. Or comment out your code line by line to see what in forsaken 9 circles of coding hell caused your problem. It's like debugging blind in a strange and overgrown forest of code that you don't even recognize because most of it is there to satisfy the needs of WASM.
And because it takes so long to debug, it takes a massively long time to create things, and by the time you're done, the dependent package you're building for has 'moved on' and find you suddenly need to update a bunch of crap when you're not even finished. All of this, purely because of a horribly designed technology.
And do they have sympathy for you for forcing you to update all this stuff? No. They don't owe you sympathy, and god forbid they give you any. You are a developer and so it is your duty to suffer - for some kind of karma.
I wanted to love WASM, but screw that thing, it's horrible errors and most of all, the WASM heap32.7 -
We can compile, transpile, and do all sorts of fucky internet things through an entire development pipeline and then troubleshoot through all sorts of hackery and dev sorcery to output html.
Or I can just index.php and be done with it.
I dunno man, I dig frontend and using the popular js libs to put shit online and be done without having to deal with the fuckery that is wasm or use something similar to Rust to bring shit to my clients.
9 times out of 10, these dudes have been well served with the php or node or even golang that i give them.
Seems that a lot of tools coming up just make shit harder.
Even VBScript seems simpler compared to the amount of web fuckery going on right now.
Yeah I keep current, but fuck, every day it seems as if shit was just getting more and more complex16 -
I am worried of a future in which JS has taken over everything, fortunately wasm is here to help :D5

I just installed Opera Mini on my PSP. That alone isn't very exciting on its own, although I am stoked that my website does in fact render on a device from 2009. With the helpful guidance of a laptop from 2004 that's doing the hotspot duties for this thing.
No, what really got me stoked is that Opera still supports these old platforms, and how small they managed to make it. The .jar file for Opera Mini 4.5 is ~800kB large. There's a .jad file as well but it's negligible in size and seems to be a signature of sorts.
Let that sink in for a moment. This entire web browser is 800kB. Firefox meanwhile consistently consumes 800 MEGABYTES.. in MEMORY. So then, I went to think for a moment, how on earth did they manage to cram an entire functioning web browser in 800kB? Hell, what makes up a web browser anyway?
The answer to that question I got to is as follows. You need an engine to render the web page you receive. You need a UI to make the browser look nice. And finally you need a certificate store to know which TLS certificates to trust. And while probably difficult to make, I think it should be possible to do in 800k. Seriously, think about it. How would you go *make* a web browser? Because I've already done that in the past.
Earlier I heard that you need graphics, audio, wasm, yada yada backends too.. no. Give your head a shake. Graphics are the responsibility of the graphics driver. A web browser shouldn't dabble with those at all. Audio, you connect to PulseAudio (in Linux at least) and you're done. Hell I don't even care about ALSA or OSS here. You just connect to the stuff that does that job for you. And WebAssembly.. God I could rant about that shit all day. How about making it a native application? Not like actual Assembly is used for BIOS and low-level drivers. And that we already have a better language for the more portable stuff called C.
Seriously, think about it. Opera - a reputable browser vendor - managed to do it in 800kB on a 12 year old device. Don't go full wank on your framework shit on the comments. And don't you fucking dare to tell me that there's more to it. They did it for crying out loud. Now you take a look at your shitpile for JS code and refactor that shit already. Thank you.21 -
Was scrolling youtube last night, not expecting much, found this video about web apps. Holy mother of linus torwalds, just watch the fucking web assembly part. https://youtu.be/MiLAE6HMr10
I'm not trying to say web assembly will be a good thing or dot net is, but holy crap!
Edit: wasm is the second topic in the video2 -
JS interview:
– we expect you to know the concepts of immutability, persistence, software architecture and systems theory, methods of analyzing complexity beyond the big-O notation, safe parallel code execution with web workers, WASM, modern web standards including working drafts, progressive enhancement and graceful degradation, WCAG recommendations and web accessibility in general, UX strategies and modern graphic design trends. Nice 20k github stars you got there. By the way, what's your opinion on modern optimistic UX?
– I know this all but I somewhat disagree with some status-quo UX strategies
– unfortunately it's a no

I've been working on an Emscripten emulation layer for a fledgling startup, and it's just a huge bitch. Seriously, Emscripten is the worst designed project I've ever seen. It embeds constants into a js file that it spits out. It turns out you can't fucking run the wasm that Emscripten emits without these magic constants from the js file.
Additionally, all the wasm imports that emscripten specifies are weirdly cased, with apparently no naming convention. They also use some weird, shitty vararg implementation when it already fucking knows exactly how many arguments are going to get passed to an import.
Also, there are a ton of broken things left over from when emscripten compiled to asm.js that they never bothered to replace with features from wasm. God knows how it even works. -
If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:
This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...
Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?
Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...
All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).
So what other options are there for making plugins in Go?
There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...
Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...
Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.
Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.
As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...
Have a good night(/day)!13 -

I've read that devRant is using javascript and the likes, what I'm wondering is how one uses javascript for android apps. I know PhoneGap exists, but I also read that there is some performance issues with it. what does devRant use?2

I've ranted about this before, but here we go again:
Go Plugins.
I was racking my brains trying to figure out how one could possibly implement plugins easily in Go.
I had a look at using RPC, which requires far to much boilerplate to be realistic. I looked at using Lua, but there doesn't seem to be a straight forward way of using it. I was even about to go with using WASM (yes, WASM). But then I came across Yaegi ("Yet another elegant Go interpreter", you heard right: "interpreter"), Yaegi is also very easy to use.
There are a few issues (including some I haven't solved yet), including flexibility (multiple types of plugins), module support, etc. Fortunately, Traefik just released their plugin system which is based on Yaegi (same company), and I got to learn a few tricks from them.
Here's how module loading works: The developer vendors their dependencies and pushes them to a repo. The user downloads the repo as a zip and saves it to the plugins folder. I hash the zip, unzip it to a cache, and set the the GOPATH for the interpreter to be that extracted folder. I then load the module (which is defined by a config file in the folder), and save it for later. This is the relatively easy part.
The hard part is allowing for different types of plugins. It looks easy, but Go has a strict typing system, makes things complicated. I'm in the process of solving this problem, and so far it should go like this: Check that the plugin fits an arbitrary interface, and if it does, we're good the go. I will just have to apply the returned plugin to that interface. I don't like this method for a few reasons, but hopefully with generics it will become a bit more clean.1 -
What do you think about Dart? They pitch it as an elegant language for everything: browser, WASM, servers, plus every native platform with Flutter.4

you don't think he's the one getting the internship amd the summer job since he's the loudest? dear god, my fist, his face.3 -
A big development company needed summer interns, the job required java and the likes and it was the first big interview i've had. This wasn't a problem, i thought, until i got there. worth noting is that Im still in school and and the last time i used java extensivly was a year prior to the interview. I completly blanked on the, rather basic, questions. needless to say, I didnt get it.2
-
I can not wait for the day till JavaScript can be thrown into the fiery pits of hell and we can just use wasm or even have the browser just support typescript natively.3
-
So I did some testing with WebAssembly to see how it works in the most recent version and without Emscripten. I installed CMake and Visual Studio Community 2015 and compiled Binaryen, LLVM and Clang for a few hours (had to do it multiple times because I used the wrong version and forgot a compile flag), ended up with over 10 GB less free space on my laptop.
All that to compile a < 1kb C file to < 1kb WASM code.
At least it works for now and can natively run in (some) browsers.2 -

Currently the only 3rd party tokenization VSCode supports is a massive pile of RegEx. There's a whole discussion about how procedural tokenization could be supported without running extension code in the UI thread. The central argument against delegating this to an external worker is that if the reply doesn't arrive fast enough it might interfere with characters typed later.
1. Any computer that can run VSCode can execute somewhere in the order of a _billion_ instructions per second. To a program, the delay between keystrokes is an eternity. The only way to run out of time here is if either the dev isn't aware that the request is time sensitive, or the framework communicates to the OS that the task isn't urgent and an arbitrary amount of work is scheduled before it.
2. Chromium is the pinnacle of cybersecurity and its primary job is to sandbox untrusted user code. You don't need another thread to do it.
3. This use case fits squarely in the original design objectives of Webassembly.2 -
Hey, i am an idiot when it comes to web development and i wanted to kindly ask a question.
I am developing a blazor wasm webapp and i want to give the user some kind of onboarding process. the kind where some parts of the ui are highlighted with explanation on what which button does or area of ui is for.
how do you call something like that? I just need something to google for.
Thank you for your invaluable time and again sorry for my stupidy3 -
I'm kind of excited about the development of Web assembly (wasm), and to see Blazor getting closer to a release is awesome.

I'm porting an OpenGL project to work with WebAssembly, I'm using emscripten to compile/generate the 'glue' to JS. Sofar I'm able to render my gl code properly through the glfw3 framework. I know you can use emscripten callbacks for input, however I was hoping to keep my existing glfw3 callback setup, that said the only callback that seems to be working properly is mouse position, window resize, keyboard, etc never get called. If anyone knows how to enable these I'd be super greatful!1

Hey devs, I'm doing a final year project for a company where I have to implement a solution using web assembly.
Now this can be anything at all from a new operating system to a virtual machine. Although I have something in mind I thought I'd ask the community too, do you guys have any interesting project ideas that can be implemented using web assembly? -
I read about wasm and being a web dev Im now scared.
So I want o learn c++. Even if not for wasm it would still be really cool to have that language in my toolbox.
Any recommendations where to start?6 -
I spent 2-3 days on debugging code written in assembly script. Apparently, you need to initialise an array using new method otherwise it re-uses the previous array from the same scope and it has created infinitely large array. Just wtf.
And I got error like "wasm blah blah blah blah blah blah".Just give proper error.
Running the environment locally wasn't an option because well it doesn't fucking work locally. So, I have to forcibly test on CI and they have created a site that can show you logs because you can't access or query data directly from server and while debugging you try to log something it randomly works sometimes and sometimes you get output from god knows which deployment. Just create a fucking API for displaying log or build a proper docker so that we test it locally.1 -

collAnon.app v2.0.21, my long running PWA/WebApp about private discussions and confrontations, is finally out with many theme and UI improvements, better forms and a lot of bug fixing ¯\_(ツ)_/¯
I'm really happy of this release of mine that I wanted to share it here.
It's also mostly self hosted with a third party, GDPR compliant, CDN (I did learn many things integrating Blazor WASM with a CDN)8 -
Is JS effectively going to become the secondary option for web once the WASM is adapted? I know that JS isn't going to die, nothing ever really dies.
So..5 -
After almost 3 years of professional experience I’d like to specialize more in something but I struggle to because I enjoy almost every aspect of IT: I find front-end really fun, I find very rewarding to build good user experiences and I’m excited for what WASM may bring on the table but I even like to work on the back end on both: legacy monoliths and modern micro services, I love to refactor clunky programs full of “cargo cult” code and redundancies put by people who doesn’t understand the framework they’re using and to make them shine. I’m even good at UNIX/Linux scripting and with Docker (often colleagues asks me advice on these topics) so I’m really tempted to upgrade my knowledge by learning K9S and reading the 1000+ pages of Unix Power Tools to get into operations/DevOps especially considering which the field is the least likely to be overrun by cheap developers coming from a 3 months boot camp.
On top of that I’ve got even into more theoretical topics: I’m following a course on algorithms and data structures in C and in future I want to learn the basics of AI for a personal project but these things aren’t much about employment but personal culture.
Have you got any advice for this disoriented young man?12 -
