But if you want to have some fun, you can try my simple program.

Here’s how it works: It starts starts the “explosion” and than engages gravity(which is just a theory btw).
In each step the program calculates gravitational acceleration for every object in the “universe” so don’t be surprised if you computer is having a hard time dealing with it(suggestions for optimization are much appreciated).

For running the program you’ll need java 1.6 installed on your computer. If simple double click won’t work, you can try run it with the command “java -jar filename.jar” from the console(if it still wont work, you can try building it from the source or post a comment).
If you want to adjust the settings use number keys or arrow keys for moving around.

Download new optimized version: runnable file 0.1b or source code 0.1b

(Older version: runnable file 0.1a or source 0.1a.)

Are you ready for some fine-tuning? ;)

Watching a TV could be a good choice, but who could resist writing a simple Fibonacci recursion in every programming language that you could think of and measuring the calculation time? I couldn’t.

So here are the results of my very scientific study for Fibonacci 33

  1. c
    gcc4.4.1            0.153s
  2. go
    8g                       0.189s
  3. java
    1.6.0_15           0.267s
  4. scala
    2.7.5                  0.324s
  5. javascript
    node.js V8        0.346s
  6. haskell
    ghc6.10.4         1.675s
  7. lisp
    clisp2.44.1       1.888s
  8. ruby
    1.8:                     22.614s
    1.91:                   2.757s
  9. python
    2.6.4:                 4.401s
    3.1.1:                  5.545s
    cxfreeze4.0.1   5.704s
  10. php
    5.2.10                10.341s
  11. prolog
    sicstus4.0.2    >10m (didn’t have patience to wait)
    swi5.6.64        Out of local stack

I have some more ideas, but caffeine level is dropping fast.
