How do I find examples of the most well made Java programs on GitHub? Don't know how to filter by how well written they are. I'm trying to become a better programmer for both myself and those who will have to read my code. I know Java is hated here but it's the language I use in my job.

Well-written is not an objective thing, in some cases.
For example, some may consider the most performant code to be the best written.
However, if that code has 10% less performance in a not performance-critical class, and is 100% easier to read, some would consider the easier to read code to be better.
Getting somewhere with my path tracer. Very noisy though, gotta improve this shit a lot still.
Looking for small compilers with easy interface to c, plus points if it can call c++.
Example from terra.C = terralib.includec("stdio.h")
C.printf("Hello, Terra!\n")
Terra is around 10kloc. There is Luck language and it's compiler is around 7kloc but it's written in ocaml.

Anonymous posting ensures that everyone has an equal say, and that unpopular opinions are not hidden or squelched.

I'm looking for code that's easy to read and maintain above performance.
>>54006559
what is that?
Writing a program that takes a .ped file as input then brute-force estimates relatedness coefficients. We have found that some algorithms that search for loops throw errors with pedigrees that have multiple intersecting loops. The point is to use this for checking against whole-genome data as a sanity-check for the pedigree structures we have.
>>54006398

Most compilers you'll find are in the 10k-30k LoC range. Lua's is pretty small. Then entire languages is around 25k for the compiler and runtime, so I'd estimate the compiler at around 10k.

Sorry, missed the "small". However, I think most of that is the stdlib. The actual Nim compiler can't be that big. If it is, my apologies, but I still think it's a great way to learn about compilers.

Performance is about the algorithms you write, not the language. Haskell enforces no runtime, so it can be faster than C.

Forth is also a lot simpler. It doesn't have coroutines, first class functions, and garbage collection (I guess it doesn't need that). Lua is still only 200kB once stripped. Bash is 1MB and Python 3MB. While being similarly performant to Python.
The JIT is all of 60k LoC and is faster than pretty much anything but AoT compiled statically typed languages because of the language's simplicity.
How do you become a good programmer (not "code monkey") if you didn't do higher math in school and didn't do a CS degree or anything like that? I know C and some C based languages like PHP and Java but it's self-taught. I don't understand how computers work.

>>54007226
calculus is useless for CS, it's basically just algebra practice
the thing about CS is that it's a very wide but shallow field for the most part, so you can kind of just study whatever tickles your fancy at the time

The money comes immediately, the skill will be made up partly of your natural ability and partly of how bad you want to be great at it.

The truth is most people won't need to worry about calculus when programming. Why bother learning something when you won't use it?
>>54007104
> It doesn't have coroutines, first class functions, and garbage collection (I guess it doesn't need that)
Forth has first class functions (though you'd probably call them words in forth terminology). Forth also has coroutines, it's just return stack shuffling after all. And GC can be added to forth, but it's usually not done.
>>54007676
>>54007668
sure most code monkeys won't need it but if you're genuinely interested in programming you should have decent understanding of math, calculus is just one of those basic things that everyone should know, and you never know when you'll need it, if you don't know it then you might think you don't need it when really you should use it
>>54007602

why?
mandatory calculus should be replaced by mandatory discrete maths IMO, the latter is much more applicable to everyday life
>>54007708
>>54007731
and ESPECIALLY to CS
>>54007731
discrete math shouldn't be called math. calculus and linear math OK, I use both at work and I am glad they teach it. Differential math is another story though.
>>54007749
If you remove 'not applicable to everyday life' courses from CS, you would be left with like 2 year worth of courses. just because you don't find them useful, it does not mean they are not useful
>>54007784
>discrete math shouldn't be called math.

Sure, you might be a great programmer and not have a degree. But if you really are good, then you probably could have gotten a degree pretty easy.

since we got some smart people on /dpt/ today, can someone tell me why we don't use balanced ternary computers?

I was doing some research on different base systems (mainly trying to see if base e had any value, but it doesn't really appear so as you end with crazy decimals for simple integers) and it really looks like base 3 is the way to go with computers. are we all just the children of IBM cuckery and blind anti-Russian sentiment?

The better way would be if college was reformed. Instead of exams that last a few hours, exams should be complex assignments that resemble real-world tasks, and students should be given a week to complete them. They should be crafted so that copying is obvious and penalized appropriately and cover the entirety of the topic in a realistic setting.

I was talking about Adolphus & Eberhard's oddly named love child.
I'm trying to create a recursive descent parser. So far I have all the foundation set, I just need to properly implement a few functions to enforce the grammar. I thought everything was right, it looks it, but I guess my Aop, Expr, or Term function is doing something wrong. Sometimes the input stream gets cut off and things aren't recognized. I don't see how though.
Is there any site or source that explains this more in depth, with code examples? Everything I've seen is very generic, which is fine, but I'm stuck on implementation.
I've searched the web near and far, and have not found any examples that helped me understand this; pls halp.
Here's the Expr Function [:::](http://pastebin.com/fzjcugme)

>>54008866
technically you're (probably) thinking of OCamlyacc
but I will say that OCaml's features are not well suited for some types of parsers. limitations on recursion (even mutual recursion) make it impossible to write some parsers using parser combinators without a lot of indirection and/or obfuscation
>>54008917
I take offense to this. Java is where its at.

If you want to apply low level skills, go to gamedev. Even unity games require C++ and gpu asm coding. If you are ready to learn then just look at http://stackoverflow.com/research/developer-survey-2015 and see what's most profitable. webdev isn't going anywhere desu, that's wahy I'm doing it. I do some gamedev and embedded as a hobby though.

wut. You can make unity games with only JavaScript ya bong.
So I've got a server with two network interfaces/IP addresses and an application that runs on the second interface. Now I write a program that needs to request some data from the application but I can't use the external IP because I need to get around the iptables timeout/rate limit, however trying to connect to 127.0.0.1 results in a refused connection as if it couldn't figure out which interface to look for the application, anyone with networked programming knowledge ever faced such issue?
>>54008913
The only output interface I use is HTML5 canvas in 2d mode. Everything is drawn with 2d lines and circles. My own code implements a quaternion camera (cam quaternion is converted to 3x3 matrix) and applies the transform to all objects in the scene. Then I simply draw them.
In fact physics part of this engine is much more interesting than graphics. See http://b.1339.cf/ohpfzzt.webm
I have implemented a simple bucket spatial hashing to accelerate collision checking, it sped up my simulation 50-100x.
The true goal of this project was to assemble a moving creature in the simulator, but it has been proven to be quite hard so far (due to stiffness issues) so I put it for later. I have some new ideas though, so the creature will be possible.

Anyone know the easiest way I can get a large amount of images from 4chan? Like a script someone has written or a premade archive somewhere? I'm thinking of making a neural net to detect anime images (so you can block them and stuff).
>>54008978
Read http://www.slideshare.net/AlexanderDolbilov/google-i-o-2014 to make games run fast they use Unity with C++ modules sometimes with code written in inline ASM. Unity is not as simple and limited as meme /g/ thinks.
>>54009038
I'm sorry that I'm not willing to spend the extra time switching contexts to lex and yacc to write a tiny parser every time I need to read some different text format. good for you if you prefer lex/yacc to combinators, but a large part of the OCaml community seemingly disagrees (considering that there are a shit ton of parser combinator libraries and parser combinators are included in Batteries)

To his defense, you have to use C++ in unity because unity is absolute garbage.
>>54009058
This was/is one of preliminary experiments, but the final goal is to do http://pastebin.com/raw/YJu443mx
Of course the whole project may be too hard, but at least implementing evolution of creatures in the simulator is possible.
Also I was thinking about porting the sim to CUDA, but my GTX580 has fried itself (literally termi!), so I'll stick with C++ multithreaded implementation.
The prototype is written in JS only for speed-of-development reasons. That's how everybody does it: write a prototype in a slow language, then port it to C++ once you know what you want.
>>54009160
you shouldn't use unity at all. but shitters use it "just fine" without C++

>virtually every single parser in the world is written in ocaml
stop deluding yourself lol
>that means ocaml is completely unsuited for writing parsers believe me I have a trip that means I'm right
it's not unsuited for writing parsers, but the way recursion works makes it extremely difficult to write parsers by using combinators

I know C/C++ asm and all other meme languages, and yet I find Unity GUI environment a pleasure to work with. It allows a dev to build scenes quickly.
There are good opensource engines - Urho3d, Godot, but they are not as convenient as unity. Convenience matters. Creating rich 3d games using a text editor only is a waste of valuable time.
