Code used on Daniel Lemire's blog by D. Lemire blog: http://lemire.me/blog/ This code is meant to illustrate ideas that I present on my blog. Don't expect or ask for industrial-strength software. It is experimental code: it can be wrong, slow, poorly coded and poorly documented. I do maintain some software meant for actual use, with bona fide unit testing and documentation. The code here does not fit in this category. == Corresponding blog posts == Code is provided in support of the following blog posts: Data alignment for speed: myth or reality? http://lemire.me/blog/archives/2012/05/31/data-alignment-for-speed-myth-or-reality/ Fast bitmap decoding http://lemire.me/blog/archives/2012/05/21/fast-bitmap-decoding/ Bit packing is fast, but integer logarithm is slow http://lemire.me/blog/archives/2012/04/05/bit-packing-is-fast-but-integer-logarithm-is-slow/ How fast is bit packing? http://lemire.me/blog/archives/2012/03/06/how-fast-is-bit-packing/ Bitmaps are surprisingly efficient http://lemire.me/blog/archives/2012/02/17/bitmaps-are-surprisingly-efficient/ Use random hashing if you care about security? http://lemire.me/blog/archives/2012/01/17/use-random-hashing-if-you-care-about-security/ The language interpreters are the new machines http://lemire.me/blog/archives/2011/06/14/the-language-interpreters-are-the-new-machines/ 3 surprising facts about the computation of scalar products http://lemire.me/blog/archives/2011/11/28/3-surprising-facts-about-the-computation-of-the-scalar-product/ Make your own programmable digital thermometer in an hour http://lemire.me/blog/archives/2010/12/24/make-your-own-programmable-digital-thermometer-in-an-hour/ For your in-memory databases, do you really need an index?" http://lemire.me/blog/archives/2010/12/20/for-your-in-memory-databases-do-you-really-need-an-index/ Is multiplication slower than addition? http://lemire.me/blog/archives/2010/07/19/is-multiplication-slower-than-addition/ Sorting is fast and useful http://lemire.me/blog/archives/2010/05/20/sorting-is-fast-and-useful/ == languages == You'll find code written in : - C - C++ - Java - Python and possibly other languages. == licensing == Unless otherwise stated, I make no copyright claim on this code: you may consider it to be in the public domain.
