The basic idea...

"The basic idea behind open source is very simple. When programmers on the Internet can read, redistribute, and modify the source for a piece of software, it evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing...
...The Open Source pages exist to make this case to the commercial world."    - Introduction to Open Source - www.opensource.org

* Derandom

market download Predicts pseudo random numbers based on a sequence of observed numbers.

Enter a sequence of numbers that you obtained from a pseudo random number
generator like, for instance, the Java standard pseudo random number
generator or the Mersenne Twister MT19937. The app will then try to
predict following numbers from the generator.

The app expects all numbers to be entered as integers or floating point numbers
between zero and one. Currently, floating point numbers are supported for the
Mersenne Twister only. Three input modes are supported:
1. <em>Text field</em> lets you enter the numbers directly on the device.
2. <em>File</em> lets you choose a file with newline separated number strings.
3. <em>Socket</em> opens a server socket on the device. You can then connect
with a custom client by means of a client socket and send newline
separated number strings to the server. After each number the server
will send back the next newline separated predictions. Each block of
predictions is separated by an additional newline.

To test the app, enter the following numbers in the <em>Text field</em>:
<code>
1412437139
1552322984
168467398
1111755060
-928874005
</code>

These numbers were sampled from the Java linear congruential generator <em>Random.nextInt()</em>. Thus, the app should detect <em>LCG: Java</em> after the third number input, and numbers in the prediction history should appear in green instead of red, indicating that those numbers were correctly predicted.

The source of this app is published on GitHub. There you can also find a Python program for testing socket input: https://github.com/asnelt/derandom/blob/HEAD/README.md
