At least it's consistent.

You'll always know why it failed.

You don't always know how to fix it, but at least you got a start.

12:51 PM

It's not a case of wanting to learn to be a "proper programmer" as such but I think learning about how memory works and such may be helpful

All the languages I work for right now abstract the magic away from me. For better or worse.

@DanPantry Rust also does a good job for learning the basics :P

Keep in mind languages which don't abstract those away are dying or niche.

It's simply not the world of today to learn C.

Debatable, C is a language that will never die

Unless you want extreme performance, portability, smallest footprint ever, the likes.

I perfectly understand they are dying

Just is it worth learning them for the knowledge side of things?

12:54 PM

@syb0rg Definitely, but in the grander scheme of things, it's becoming less and less relevant for the average programmer to know a thing about it.

#include <iostream>

int main() {
  std::cout << "Hello, world!" << std::endl;
  return 0;
}

That's mangled C++, not C.

This basic code fails on a Mac due to very obscure errors from templates. Excellent.

Drop the return 0;, it's implicit.

Yes, I'm trying out C++ because I can't get valgrind installing behind this firewall.

(but gcc is already installed)

12:56 PM

If you're feeling up to it, sure, learn something low-level. Pick ASM for all I care. Whether it's 'worth it' is subjective though.

Will it open your eyes? Likely. Will that benefit you in any meaningful way when writing web applications? Meh.

I'm an idiot.

I was compiling C++ with gcc, not g++.

Well, back to JavaScript.

If you're looking for a side project, I'm sure @syb0rg won't mind you taking a look over the Khronos repo :-)

It is probably the nastiest exception you could ever get. Invariably caused by native code corrupting the GC heap. Well, you have some. The exact location where it crashes is rarely the place where the corruption occurred. It isn't detected until the GC collects the heap, that always happens later. A good code review, unit tests, randomly commenting out code is the way to get somewhere. — Hans Passant 6 secs ago

Christ, no. I'll break everything.

Impossible, it's already broken

Actually tho, if you install portaudio with your package manager then you should be able to compile it with my instructions

"Self-sponsored team building" has to be the stupidest idea a manager could ever think of. If my manager ever came up with some rubbish like that, I would rather keep my money than attend some fake event which will supposedly build the team. And if they have a problem with that, and push their "team building" too much, I will just build my team somewhere else. Does that sound like "team building" to anyone?

1:11 PM

@CrazyNinja Small Help

I have a string which includes a arithmetic section. So I wanted to extract it out and fill those values in a object.

I know the arithmetic format, therefore before subString() I could check whether that String part is available or not

This is one sample string

3 x 60 x 1 kapsel/kapslar

So, I want to extract out 3 x 60 x 1 potion

Is the arithmetic always at the beginning?

i wrote this simple regex pattern

@syb0rg yup

^\d{2} x \d{2} x \d{2}.*

Don't use regex, this is easier than that

Nuke everything not a number or operator. You don't need regex for that.

1:14 PM

subString?

This is called a code review. Also, we can't reproduce this. This is type of XY problem, when you focus on the solution rather the problem. We need to understand the problem in order to provide solutions. If you want someone to review your code, try at CodeReview SE — David Arenburg 16 secs ago

@Pimgd That's because of node_modules

he should be deploying the compiled static files, node_modules should only exist on a build server

Any interesting questions or answers lately?

If you're patient enough, give it a day or so to cache up.

@Mast Meh, you can install modules globally if you want it that way.

Plus, that's not a "simple hello world" project.

That's a "simple hello world" in a dialect of JavaScript that isn't available yet using a framework and for the browser with the JavaScript equivalent of Maven or Gradle.

It would be analogous to installing Spring.

2:08 PM

Oh, right, Gradle. Awesome stuff, hard to figure out what goes where.

You could throw something together a lot simpler without all of that cruft if you wanted to.

The upside of the approach JS takes though is that you only ever install what you need. If you don't need Babel, you don't install it

I don't think it's on-topic. It's one single function. One.

It's really short code though?

@Mast I don't think it's stub code. IMO, stub code means "not enough context to offer any meaningful advice". There, I could probably say, at the least, put it in a function that takes the values as parameters

@Hosch250 No, you are the dumb dumb.

@N3buchadnezzar I didn't say I wasn't, did I?

@Zak Maybe that is how it starts. You have so many bookmarks that you start using tabs. It is a slippery slope. Soon you will start writing down urls on post it notes.

@Mast The argument doesn't have a type?

How does that even compile?

@skiwi Oh, it had a type allright, it just didn't have a name. So the compiler thought I forgot the type and typed the name instead.

I saw the const and my head somehow misinterpreted that as a type.

No red flags were raised where there should have been sirens.
