weekly programming contest

Name: Anonymous 2009-12-21 17:24

so i thought since /prog/ is filled right now with non programming related bullcrap. how about we discuss about a official weekly /prog/ programming contest. we could make one each week. we could discuss a debate on the subject 2 days before the assignment.

it would really increase quality posts and programming related subjects, and add some posts here because it seems a bit lame here. also the nonprograming related bullshit i think might exsist because of boredom and we all know how bad boredom is.

discuss. NOW!!!

We had one of these a while back. I'd find the thread but I have no goat.

This week's task: Make a program that takes another program's source as input and decides whether, for a given finite input to the program, if the program will halt or not, without compiling+running the program.

That's easy as fuck. Just tell me how much memory the machine has (RAM + HDD + hardware registers + mechanical states + expansion/external such as other networked machines or the Internet if it's connected to it).

Challenge: write a C++ parser

Name: Anonymous 2009-12-21 18:03

While I am always in favour of actual coding threads, I have several concerns.
1. Like the `game ideas' threads, these contest idea threads end up being all talk and no walk. If you have a contest idea post it and see if it takes off.
2. If give something a week timeline, it will be forgotten. People will procrastinate and never actually code up a solution, or the thread will leave the front page with half a dozen posts. A shorter timeline is more likely to work.

These challenges should be doable in at least half a day's work or less. If you think the problem you proposed ca be done in that timeframe, but other's don't think so, you should post some demo code to prove it.

Possible challenge idea:
Write a simple compiler(to bytecode) for a toy language(imperative or functional, no ABC or Brainfuck toy compilers please. Subsets of real languages allowed.) of your choice. To simplify or avoid lexing/parsing tasks altogether, one is allowed to use Lispy syntax(this isn't a requirement, but would simplify the task somewhat).

*compiling to C/ASM or other languages allowed too.

Challenge: POKe/prog/ BATTLE!

Simulate a single pokemon battle between two trainers. No Items, each trainer has only one Pokemon. Each Poke/prog/ has the following stats:

Speed: Determines which Poke/prog/ attacks first
Attack: % to increase damage
Accuracy: % to hit with abilities
Dodge: % to avoid getting hit
Defense: % to reduce damage taken
Health: Amount of damage that may be taken before KO

And 4 Abilities that may be used during combat.

(loop repeat 1000 do (print "Sussman"))

What do?

It's just LOOP syntax for running arbitrary forms.
Here's another one (dotimes (i 1000) (format t "Sussman~&"))

loop repeat do
And they say Java is verbose.

Nobody is forcing you to use LOOP, however you're right, I find my Lisp code to be somewhat verbose, since I tend to give my symbols long descriptive names (which is not a problem as long as there's auto-complete), so I could read them at a later date without wondering what I meant. Of course, if you really use statements like that often, and dotimes isn't good enough, you could always write a macro which looks like (repeat 1000 (print "Sussman")) if you wanted (it would only take 2-3 lines of code tops at that). Does Java give you as many options to avoid verbosity if you so desire?

(defmacro repeat (times &body body) `(dotimes (,(gensym) ,times) ,@body))

Right, that's so much more readable than
for (int i=0; i<1000; ++i) { ; }

Apples and Oranges. >>22 is a macro for his repeat construct show in >>21. If you were to make a C macro for your post you could have accidental variable capture.

You mean FIBONACCI PONG-TRIS?
I never got around to doing that one. Now that I have 2 weeks of vacation on my hands, I might just give it another shot, though.

Whose bytecode? Can we make one?

Hahaha. Like anyone programming in the C family thinks farther than #DEFINE COPY_AND_PASTE_PROGRAMMING 1.

Name: Anonymous 2009-12-22 11:17

Suggestions:

- Tetris (or Pongtris or whatever variation you want)
- A C Compiler
- sagebot

You can make your own, but you should provide at least a minimal interpreter, so we could test it. Otherwise, you're free to pick some bytecode out there that already have interpreters/compilers/JIT(s) written for them, as long as we can test them out ourselves.
