Case Studies * Used by FolderShare to compress peer to peer transfers between OSX, Linux, and Win32 machines of files up to 4GB. Compression was automatically disabled for media that was already compressed (photos, music, etc). text/html 2008-07-10T18:09:30-06:00 http://www.spiteful.com/dd/libevent?rev=1215734970&do=diff Overview libevent is a cross platform library that abstracts out the different notification APIs (specifically, /dev/poll, kqueue(2), event ports, select(2), poll(2) and epoll(4)).

Brad Fitzpatrick originally wrote it to help LiveJournal scale. Case Studies * Facebook uses and contributes to memcached. As of April, 2008, Facebook was using 805 memcached servers. From the same source, Wikipedia was using 79, Flickr 14, and Fotolog 40. text/html 2008-04-29T10:43:43-06:00 Tom Kleinpeter http://www.spiteful.com/dd/start?rev=1209487423&do=diff Are You a Developer or Tester? Have you ever had a hard time deciding if a library or tool is going to work once you really start using it? This wiki exists to help developers research their options and/or document problems that have wasted their time in the past. Check out Tom's blog post for a longer introduction, or look at jquery, sqlite, or zlib to see some examples. text/html 2008-04-28T15:45:04-06:00 Jonathan Tang http://www.spiteful.com/dd/firebug?rev=1209419104&do=diff Overview Firebug is a Firefox add-on for debugging JavaScript and analyzing HTML, CSS, and the DOM. Gotchas * Minified JS files can result in incorrect function names in the Firebug error console and profiler.

It is integrated with PHP. Case Studies * Audiogalaxy.com used it to build graphs of music popularity over time. We also used it to chart internal statistics.
