What do you guys post code to, made something I can't post to github so looking for a more lenient alternative

don't want to use pastebin cause it can't have readmes and shit like that

You should never use the unsigned types, they are slower and using them with signed is a mess.

I'm making a decentralized, dead simple to use, television system. It can run on a Raspberry Pi and dial-up. Dial up is free in a lot of cases, and all parts included costs around ten. Multi-screen setups, Bitcoin donations, multiple quality settings for all connections and setups (current max is 4x4 8K screens), and an extensible macro system to control it. If anybody is interested, tell me on Tox at B183A4A9CC9E026DF4345EA31ACBE185ECA39656210F38736BBED62AD68DCF4F7E08A5D9960E

The American flag symbolizes The Utopia. In a perfect world, America will be The Utopia of Libertarian freedoms, but that is impossible. However, for being impossible, seeking perfection shall not be in vein, and the flag is a reminder that a brighter future is ahead, regardless of what country takes the role of supreme liberator, the center of The Utopia.

>>57017642
The user can specify fonts and colors.

The color scheme or the color of things aren't part of a terminal emulator, all a terminal does is render what it's asked to.

That stuff is handled by the programs that run inside the terminal.

>>57017642
>Can Emacs do this
Emacs can do everything, but it isn't portable if you add a lot of functionality. Magit manages pretty much everything in Git in the most elegant way possible. However, you should get comfortable with a non-GUI environment and the macros to get the most out of Emacs

I wonder why modern terminals have stripped away so many of the features that older terminals needed to use.

Can your emu actually run incredibly old programs? If so, what platform? Are you emulating any particular platform, or just the terminal itself?

That's one of the reasons I want to learn a flat text editor, I want to be able to work in systems even where there's 0 access to anything visual(I.E. writing a script on a server)

>>57017714
I've been working on it for a week, it baraely supports basic controls to run vim and a shell.

I don't plan to implement anything that isn't needed, I don't want to make the next xterm or rxvt, those already exist.

I'm just making a modern terminal, with as fast as possible rendering and the features I need, which I can't find in any terminal that exists.

>>57018115
Lexical borrows are a pain in the ass.

The borrowing semantics of inherent impls methods become impossible to work with as soon as you start mixing mutable and immutable calls within the same method. (the methods don't know you're actually touching unrelated fields in the same struct, because the borrow checker is dumb).

There's no way to tell the borrow check that a method taking &mut self and returning an immutable reference doesn't need the lifetime to be bound to the mutability, i.e. dropping the mutability of the reference on return. (this is useful for methods that mutate and return immutable references within the struct, you won't be able to call anything immutable on the value again while those borrows are active).

Any recommendations for first language ( i know bash but is more a scripting language)
Basically this is just time off work so like 2-3 hours a day

>>57018115
The specialization RFC doesn't cover a lot of really required stuff.

To, for example, do something when two generic parameters are the same, and something else when they're different you have to jump backwards, and then you can't even make it generic, you have to pass the concrete types because the genericity rules are way too strict.

Even assuming the lattice rule is accepted and implemented, it won't be enough, and it will be years before anything that covers what's needed is stable.

Macros in Rust are complete and utter shit as soon as you want to do anything a little more complex, the hygiene is limited, there's no modularization, and there's no eager expansion. Macros 2.0 should cover all those issues, but again, it will be years before anything is stable.

Macros 1.1 brings at least some often used crates up to stable with the introduction of gimped procedural macros, but clearly if you're not a crate that has a bajillion of users they don't give a shit about you.

>>57018115
Compilation times are utterly awful, one of my crates started requiring 20 minutes to compile, and it's roughly 2K LOC.

Incremental compilation isn't going to fix this specific issue either, because it's not about recompiling, it's just awfully slow.

There are a bunch of other issues too which I can't recall right now, Rust a shit.

Write a script with a loop that runs 4 times and sleeps for 300 seconds after doing the task.

That would only work if the task takes 0 seconds to finish. This one will so it's good enough, but it's still a lazy solution because if you increase the time complexity at all it stops working properly.

Posting from last thread. I'm taking a data structures class, and it's shit. Lectures are just the prof rambling about shit and sometimes typing something in CLion, we have no textbook, no real syllabus, and have had 2 lame assignments since August. It feels like a waste of time.

Is there a good free online course for data structures with C++?

<div ng-app="myApp" ng-controller="myCtrl"> 


<h1>{{myWelcome}}</h1>

</div>


<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
  $http.get("http://localhost/API.php")
  .then(function(response) {
      console.log('success', response);
      $scope.myWelcome = response.data.name;
  }, function (error) {
       console.warn('error', error);
     });
});
</script>

Try this, format as you like. The second arg to get is the failure callback. If there's something wrong you should see it log the error. I suspect that it's working, but that you're using the data incorrectly - data isn't name, it's the entire body of your get request. response.data.name should get you "1456848891298.webm", in your example

I don't think so. If no JS ran it will just render the HTML as is, hence {{myWelcome}}

Are you sure? Open the console first and then refresh.

Do you know how to use the debugger? Put a breakpoint on your first JS line, var app = .... and inspect the your variables.

If you're not comfortable with the debugger, put log statements all over your code. Put one on the first line of your script and right after it. You want to see how far your program runs which should help you see what the problem is

Its probably just my coding. I'm supposed to make one more efficient.

What we're doing is searching for a phrase within a string and replacing said phrase with another.

What I've done so far is:
Split a string using the phrase which put those into an array.
The initialized a linked list with array[0], then add the new phrase and then add the next item in the array. And repeat for the length of the array.

I've tried adding new nodes for each array item but it seemed a lot slower than just concatenating the strings. So I have no idea how to make it more efficient.

>>57020528
One doesn't exist, and you know it.

>>57020611

maybe it has to do with the fact that you have an app inside an app? I don't know what the problem is, but Angular is definitely not running properly

>>57020582
If it's not even logging then your JS isn't being executed. I'm not too good with Angular but shouldn't you only have one ng-app? Delete ng-app off the body and try again.

If your project is small enough you might not need all of that overhead. And it's a good habit to get accustomed to bash, it's super fast and can do just about everything you could ever want.

>>57021009
I don't really get a choice one of my classes is literally all about bash scripting and the other one was C but it became makefile shenanigans along the way

>>57020981

Bash and Make are useful tools to learn. Bash because of its use for general system scripting, and Make because it is one of the more common build systems used for C and C++ programming. When not written in directly, it is nonetheless common to use Makefile generators for more complex cases.

>>57019252

it's not about learning to program it's learning about logic and how computers interpret things then translating those concepts to any programming language out there. so start doing logic puzzles, learn some syntax with python or whatever and learn some discrete math if you're that dedicated. Also boolean algebra is a good thing to pick up.

>>57020939
Don't try to learn a framework before you even know how JS works. You're doing way too much at once with Ionic and Angular. Also, the guide you're following is also way out of date. Angular is on version 2.something now, and the latest Angular 1 is 1.58. Maybe that syntax doesn't even work with an older version. I agree though - JS sucks for beginners.

Don't generational/moving garbage collectors make linked lists much more efficient? Cache locality can be maintained and allocation in such GC schemes is absurdly cheap anyways

Compiler ignores you. A massive waste of time.

>>57021169

>>57021199

There are some cases where the register keyword has provided better performance. Most of the time, the compiler is pretty damn good at doing register allocation itself, and the compiler is free to ignore your usage of the register keyword if it so pleases.

I would not use it in regular code, but when doing optimizations, it might be one approach for speeding up certain sections...

Almost never.

>>57021414
we're talking about the register keyword in c, not about how often you get laid

>>57021340
IIRC the register keyword does absolutely nothing and is entirely ignored by compilers, and spits out a warning as such. That may just be specific compilers though.

Currently learning python...

Kind of confused on immutable/mutable data types.
So I know immutable data types are types that can't change once they're created, but int is an immutable data type, yet something like this

foo = 5
foo += 5
print(foo)

correctly evaluates to 10... What am I missing?

>>57021766
i've never programmed in python, but from what i understand, if you do

x = 5
y = x + 1
x = 9

y will be 10. is that what you're talking about?

>>57021792
>y will be 10

In what retarded language does such a thing happen?

>>57021766
>foo += 5
is going to give you an error in python

It's because you're reassigning foo.
ie:
>a =1
>b=a+1
>b==2

Instead in your case b is also foo.

Trade offs. Java trades off performance and features for ease of use. C++ enables good performance and is feature-filled at the cost of being one of the more difficult and complex languages. Go is less general-purpose so it can be good at what it focuses on while being still pretty easy.

>ghc bug casued it to delete source code files if it had a type error

hahahaha

>>57021848
Basically, it comes down to certain languages being better at certain things.

Example:

MATLAB (Technically a programming language) is a really cool calculator you can use to solve linear equations in an intuitive and effective manner.

C++ could also solve linear equations, but you would need to do a lot more work to do it and it wouldn't necessarily be as efficient as something designed to solve those linear equations.

This wasn't the *best* example, but it shows how each language has its own pros. Ex: Java is widely considered a "safe" language because you have to make it crystal clear what you want to do before you program a large amount of objects, but it's not as fast as something like C++.

>>57022066
Maybe the haskell compiler links the binary with the entire Haskell standard library (if that's a thing, I'm not sure, not a Haskeller myself). Which would explain why.

For example, if I compile a barebone C++ hello world it will be only 9 kB, but that's with dynamic linking, but if I compile it with -static-libstdc++ and -static-libgcc (which is probably what's happening by default with Haskell), the binary will be 1.2 MB instead.

>>57021269

Why Radare2 is such shit? It's been in development for a decade and it feels they need to abandon it and start a new project again. (Maybe this time with background analyses).

It can't `aaa`nylize fucking /bin/bash, forget about vidya (I tried witcher 3, gave up after more than hour).

And that's bad: more and more vidya move to x64, so free ida doesn't cut it anymore, and demo binary ninja is useless (can't save projects).

I also still hadn't figure out how to use `asm.emu`lation if it's even possible (e.g. in crackme03 there's basic arithmetic challenge, I used gdb to get the result)

Oh, and its frontends are complete garbage (bokken and web UI) that crash the moment you look at them funny. Or just for fun.
