I remember the first time visiting /dpt/, there where a lot of guys talking about cool programming stuff and interesting projects. Now it's a piles and piles of crap not even near related to programming things. Can we return to the old days?

>>61100986
learning python like a moron.

How would I take a string like 'item1 | item2 | item3' and slice out item 2 only? data[7:data.index('|')] only returns ''. I feel that this is a simple thing that I am overlooking, but I just can't see it.

JavaScript that's run by v8 engines which returns strings for C# to build web pages that are sent with a dodgy server. This way, to make webpages you just write the boring html, add everything like this

var ScriptedPage p = new ScriptedPage("main.html",new {name = "Larry"});

For the simple hello world of most templating libraries.

There's also a function you can set so this happens at runtime, also I've implemented 6 different JavaScript templating engines.

>>61101399
That's because we require too much individual training and make too much money for collective bargaining to make any sense.

There's a huge divide in skill in CS. The most influential employers don't want unions because it would cost them a lot of money for dead weight programmers. The most influential programmers don't want unions because it would weigh down their salary and they'd make less money.

This kind of thing is why WHITE COLLAR jobs like software developers almost never properly form labor unions and when they do they're never big.

The paper is old like a shit of a mammoth, it contains PDEs and a solultion using finite-difference method just like in fluid dynamics. It isn't hard, it's a level of a CS undergraduate.

>>61101586
I mean the CS undergraduate level is sufficient to implement it in a code. To write a paper like this really requires good understanding of the physics of the process, classical mechanics to be precise.

>>61101635
Yep, specifically visco-elasticity. It's a really undertaught subject desu.

>>61101643
In the sense of physics it isn't straightforward, I agree. But you have already formulas to compute it, there's no need to bother if your part is to write a fast code for it, not to do research.

>>61101043
You're dad gay

>>61101643
In my opinion these things in computer graphics such as Monte Carlo integration, some dynamics with PDEs aren't actually rocket science. The success of Arnold Render or Nuke is not because they did some super discoveries, they just provide a good scalable and flexible code needed for the industry.

If you can write a code which you can put on several servers and GPUs to compute this simulation it will be more useful in practice than fucking around about physics.

unlike the gargantuan projects /g/ usually engage in, making a compiter that does lexing, parsing, a bit of typechecking and then outputs some C is pretty simple.

then we name it something politically incorrect, put an ASCII cock in the CoC file and market it as an alternative to rust

So, I'm thinking of creating my very own text editor with all the kool features I want, but I don't really know where to start with the rendering of the text itself. How do text editors like Emacs generally render their text, do they delegate it to UI libraries like GTK or the windows API, or do they render them themselves using things like Cairo or something of the sort?

My intention is to make something as low level as possible, and I'll be using c++. The idea is to use a graphical user interface (AKA, I'll not be running the program on console). What are some good, open source, editors I should check out; preferably not monsters like Emacs.

Thanks for the help in advance.

anyone else here learning programming but not sure what they actually want to do with such a skill? I enjoy solving problems and i basically just do a bunch of exercises but i've created very little of my own ideas. I guess i'm mostly interested in just how the world runs on programs, stuff like computing systems inside of machinery, embedded systems and networks.

Ermm... how do I share my files only with special people?
I used pastebin, but I seem to not understand it very well.

Mindless fun perhaps? You were looking for a project, and the world doesn't have nearly enough programming language variants that no one will ever use.

>>61103171
Some examples:
Pretty much every library assumes concurrency is something you'd never want to do.
"God-functions" that try to do everything for you, rather than concise, modular parts.
Cross-platform sucks, and you'll find a lot of documentation about "cross platform" talking about decades old kernel versions.
A lot of standard abstractions are borrowed from imperative programming practices, rather than the couple decades of development of Functional Programming's practices that even imperative languages are picking up now.

Really, you'd just have to use it and get a feel for it.

nice math homework, nerd.

Filthy casual learning ruby here, I don't understand the syntax of the .sort_by method.

For example if I have a hash assigning numbers to colors and I want to sort it from highest to lowest it goes:
hash = hash.sort_by { |color, count|count }

What I don't understand is the |color, count|count part. Especially since I can remove the "count" at the end and it gives me the same result.
Could someone explain?

>>61103297
Plenty of libraries use bordeaux-threads or lparallelism. Look through quickdocs and tell me how many "god-functions" you see. I certainly don't see any. Cross-platform shouldn't be much an issue unless you heavily rely on FFI, but FFI is kind of a clusterfuck no matter what you use. You'll need to elaborate on your last point. CL can be written in an imperative way obviously, but there are plenty of FP related abstractions.

>>61103474
*lparallel

>>61103429

:sort_by is a method on Enumerable objects which sorts the elements of an enumeration, but instead of comparing the elements directly, passes those elements to a block and compares the output of that block. In the case of a Hash table, the elements are a two element array which can be split apart into its elements as separate arguments to the block. In the example you have provided, the hash is sorted by the values, and completely ignores the keys.

By the way, if you find you don't understand how some enumerable method works, be aware that you can put whatever you want in a block, including print statements!

irb(main):001:0> { hello: 3, world: 2 }.sort_by { |x| puts x.inspect; x }
[:hello, 3]
[:world, 2]
=> [[:hello, 3], [:world, 2]]
irb(main):002:0> { hello: 3, world: 2 }.sort_by { |x,y| puts x.inspect; y }
:hello
:world
=> [[:world, 2], [:hello, 3]]

>>61103553
Thanks. I haven't gone over blocks yet, but
>the hash is sorted by the values, and completely ignores the keys
So in the |color, count|count part, I'm telling ruby that in the hash, color is the key and count is the associated value, and that it should sort by count?

I'm thinking of implementing 8ch to this, but I don't know if they have APIs/json support for their boards.

>>61103600
Looks fine. I'd add in an option to make it oneshot instead of it looping forever, but that's trivial.

>>61103698
I made it loop forever so when a new image is posted, it will automatically grab it after it refreshes. Also fixed an issue with the refresher running to 0 and staying 0.

Maybe add an option to do exit after a download? Or the other way around maybe.

>>61105076
Ideally you should write your tests before your code, but not many people actually do this. I don't see a reason to write tests on a separate day, if you have time to write them both in the same day (in any order) then go for it!

Writing a tcp file-transfer program in C++, that respects rfc791. I wrote something similar for UDP in C, but this time I am learning the OOP features of C++ and TCP sockets simultaneously.

Not too much to brag about yet, the lexer was written using Ragel and the parser in Bison. My biggest roadblock so far was getting the two to work together, but other than that it's chugging along nicely. Right now I'm just incrementally building the grammar up and working on the parse tree. I'll probably throw it on Github once there's something more substantial to show off.

Those are both me. A function having a different name doesn't make it hard to learn. Calling a function select instead of map does not negatively impact it's usefulness or conciseness. It might be slightly less intuitive if you expect C# to use the same idioms as Python, but that would make you an idiot.

That's not really possible without removing most of the language, in which case it isn't really "building on it". And being heavily influenced by a language isn't the same as "being built on" it.

"select" is less intuitive (completely unintuitive), useful (limited to SQL analogies as a word) AND less concise than "map"

Use an imperative language with FP support

Only if you've only ever used Python. In the designated shitting language it's called select, and in SQL, both of which have larger user bases than python.

How, it does the same fucking thing.

It's not less concise than map, unless by concise you literally mean "number of characters" in which case you're being a pedant.

"Map" is intuitive because you're mapping
"Select" is not intuitive at all. It's SQL jargon.
Map is much more intuitive than Select.

>how
I literally just told you that the word "select" is less useful than "map" because it has a restricted application.

We're talking about one fucking instance, obviously I could go on to say that C# FP is utterly disabled by a limited type system but this is a single point.

Rust's borrow checker can get annoying and it bloats up the syntax/general way you do things.
D is just the c++ youve always wanted, shorter and more logical syntax for most things. The prime example being . vs ::

>>61107229
Ignore the dumbs that think that merely adding lambda expressions to a language makes it support FP. Among the ones I know you could try OCaml or Scala. Or just Haskell with ST monad.

>>61107415

d was dead on arrival with nobody wanting to touch it because of concerns with proprietary licence baggage, regardless of that not being an issue almost immediately after release, along with a change in the language equivalent to the python 2 > python 3 change but while still just being called d officially, with people referring to the change unofficially as d v2

rust on the other hand right now is more popular than d ever was and you have people actively using and recommending it so much that just mentioning rust on /g/ will have an army of autists countershilling it because sjws or some such nonsense

Well, ST monad lets you do imperative programming in Haskell, like mutable variables and arrays. So I guess it would be functional language with support for imperative programming instead. I just like Haskell and think that ST monad is pretty ridiculous so I wanted to mention it.

I'm supposed to make a kind of spreadsheet program that takes in a list of formulas: (simplified ambiguous grammar)

<formula> ::= <name> = <expression>
<expression> ::= <name>
<expression> ::= <constant>
<expression> ::= <expression> <binary operator> <expression>

I made classes representing expressions:

abstract class Expression
{
   Value eval(Environment env);
   IEnumerator<Variable> dependencies();
}
class BinaryExpression : Expression
class Constant : Expression
class Reference : Expression

The dependencies part got ugly because apparently you can't call it with

foreach(Variable x in expr.dependencies())

, because it expects an object with

GetEnumerator()

method. So I have to write ugly code like

IEnumerator<Variable> a = expr.dependencies();
while(a.MoveNext())
   doStuff(a.Current);
