* FunStuff

A place for all the fun stuff I do.

** GNU-Parallel

GNU Parallel is a program for running command-line tools in parallel.

map.pl and reduce.pl implement a Map/Reduce analysis of the flight

data set. You run the analysis

using the command:

#+BEGIN_EXAMPLE

    cat On_Time_Performance_1H2012.csv | parallel --pipe --blocksize 64M ./map.pl | ./reduce.pl

#+END_EXAMPLE

** LEGO

Various experiments with LEGO Mindstorm. Most of these experiments

have been published in Alt om DATA.

** Comal

Retrocomputing in COMAL-80 (using OpenComal).

  - fib.lst :: Fibonacci numbers

  - sieve.lst :: finding prime numbers

  - brussel.lst :: simulation of Brusselator using simple Euler integrator

** JavaScript

Just a couple of JavaScripts experiments.

  - graph.js :: a "library" for handling directed acyclic graphs.

** Extensions

A model extension for Node.js and Python. C++ classes are wrapped as Node.js and Python classes.

  - person.cpp and book.cpp :: C++ classes

  - person_wrap.cpp and book_wrap.cpp :: Wrapper classes (Node.js).

  - py_person.cpp and py_book.cpp :: Wrapper classes (Python).

Notice that both Python 2 and 3 are supported.

Building C++ classes:

#+BEGIN_EXAMPLE

make

#+END_EXAMPLE

Building Node.js extension:

#+BEGIN_EXAMPLE

node-waf configure

node-waf build

sudo node-waf install

#+END_EXAMPLE

** Pi

Implementation of calculation of pi using Monte Carlo in various

languages.

Currently supported languages:

  - pi.sh :: bash

  - pi.py :: Python 

** C++

Experiements in C++

  - try_catch.cpp :: How to use lambdas to wrap exception handling.

** Misc

Just a collection of small programs.

  - hailstone.c :: generating hailstone series (see http://en.wikipedia.org/wiki/Collatz_conjecture)

  - fraction.py :: implementation of rational number arithmetic in Python.

  - opg1A.py and opg3A.py :: simulations of Svante's home work in probability.

  - greeting.cob :: tribute to Grace Hopper.
