Funny text generator (Python)

2011-12-25T11:14:39-08:00

Python recipe 577988 by Pierre Quentel (generation, random, text). Revision 4.

This class takes a text (preferably long enough) and generates another text that "looks like" the original. It won't mean anything, or just by chance ;-)

For example, taking Hamlet, Act I, the program generates things like :

Hamlet

And vanish'd from our watch;
His further. Fare third nights of the flushing immortal as it draw you into the flushing thy complete steel
'Tis sweet and each new-hatch'd:
A country's father;
To business and is prodigal thee!
Have of crowing more the should I have heaven,
Forward, therefore as ourself in the business it, Horatio
To what is't that your watch, bid this here!

Usage :

generator = TextGenerator(txt)
result = generator.random_text(3000)

Some prime generation algorithms. (Python)

2010-08-06T11:20:34-07:00

Python recipe 577329 by Thomas Lehmann (generation, is_prime, prime, primes). Revision 4.

Basic idea was to see the difference between different prime algorithms in time. Also they are not perfect the output shows that really higher numbers let grow the difference why I have separated this into functions to make it visible. I add this here because I have been missing this very often when I have been searching for algorithms.

The 'is_prime' is a well known way of checkin for a number being prime or not.
The sieve of Erastothenes is simply to strike out multiples of a given value; the primes will remain.
the function 'profile' is a decorator for functions measuring the execution time
Some information are in the comments of the code

Planet Terrain Heightmap Generator (Python)

2010-03-10T16:35:37-08:00

Python recipe 576929 by Shea Kauffman (creation, generation, generator, heightmap, landscape, map, pil, planet, planted, pygame, terrain, world). Revision 9.

The process is simply: 1. Take a plane 2. Cut out a shape 3. Make it a little taller 4. Repeat

Similar to the spherical landscape algorithm by Hugo Elias.
I found a combination of Ovals and Triangles to produce the best results.

Generate a salt (PHP)

2012-07-10T19:52:17-07:00

PHP recipe 576894 by Xavier L. (crypt, generation, generator, hash, pass, password, salt, secure, security, string). Revision 6.

This function will generate a salt for use with passwords ranging using characters in range a to z, A to Z, 0 to 9 and !@#$%&?. The characters are sorted in a random value and can appear more than one time in the string. This way, this function is more powerful than the *shuffle() function. This means that the salt could also be longer than the character list.
