The under 100 line challenge!

[Enderman]

for x in range(100000):        print x

This program helps you count.

answer=0for x in range(10):        answer+=xanswer-=3print answer

And this program gives you the answer to life, the universe, and everything.

My coffeescript function that can check if the user entered a valid Austrian social security number.

I tried to make it as small as possible, so don't expect awesome code quality.

soz = (soznum) ->  num = soznum #this saves 1 line!  if num.length != 10 or isNaN(parseFloat num) or !isFinite num then return "Keine gueltige soz. versicherungsnummer!"  while true    sum = 0    sum += ([3,7,9,0,5,8,4,2,1,6][i]*parseInt(num[i])) for i in [0..num.length-1] when i isnt 3    if sum%11 > 10 then return "Keine gueltige soz. versicherungsnummer!"    else if sum%11 == 10 then num = (parseInt(num[0..2])+1)+num.substr(3,num.length) else if num != soznum then return num else return "Gueltige Nummer"

Written quickly and probably isn't the most reliable but its exactly 100 lines and works on 90% of the TV shows i have on my computer.

 

Will organize your TV/anime video files to a Show\Season x\ShowName SxEx - Episode name.extension

Only works on window, didn't add system dependant file seperators.

Usage:

   -compile with javac (need SDK and bin on system/user path)

   -execute; java VideoOrganizer [Full path to video directory] or place class in target directory and execute without params

 

Works on 90% of files tested but the wide range of potential formats cannot be easily covered with regex

On a trip to Southern California I had made a quick python program (no spoilers yet) in a notepad app on my phone (so extremely painful) and my phone died before I could save . So I am trying to re-code it. I will post once I have programmed it.

Nice calculator! There are probably some more modifications you could make if you wanted it even smaller.

Checking if the input is a number is done twice.

How hard would it be to do something like this in a assembly language? Assuming I've got a decent to good knowledge about the language. Its a bonus project to write one in assembly (1st year computer science and engineering university student). But how hard will it be?

I made a little something to convert decibels to watts/m² for Algebra last year. Not very impressive but it works.

http://jadar.net/2014/04/08/decibel-watts-converter/

 

I also made a little set difference so that you can find the degree of a polynomial from a set of data. I'm still learning Python, so it's not the cleanest..
