gregnavis / Makefile

Last active September 4, 2015 02:44

A simple generator of Clifford attractors. Issue `make` to build it (requires `libnetpbm10-dev` on Debian).

gregnavis / sudoku.rb

Created April 13, 2013 22:44

A simple Sudoku solver in Ruby.

	class Sudoku
	SIZE = 9
	NUMBERS = (1..9).to_a

	def initialize
	@board = Array.new(SIZE) { Array.new(SIZE, nil) }
	end

	def [](x, y)
	@board[y][x]

gregnavis / call_tracer.py

Created February 26, 2014 12:23

This is an example of an automatic call tracer that can report the whole call tree. I use it instead of adding lots of logging statements.

	import bdb


	# This is a custom debugger that calls the specified handler on each function
	# call.
	class _CallTracerBdb(bdb.Bdb):
	def __init__(self, call_handler, return_handler):
	bdb.Bdb.__init__(self)
	self._call_handler = call_handler
	self._return_handler = return_handler

gregnavis / insert_query.rb

Created April 15, 2015 21:44

An InsertQuery object that can be used to insert models in bulk.

	class InsertQuery
	def initialize(model_class, column_names, returning = nil)
	@model_class = model_class
	@column_names = column_names
	@returning = returning

	@rows = []
	@executed = false
	end
