We had an internal tech meeting day today, and among other things, three speakers presented brief tutorials: * Asher Feldman on profiling/performance optimization: https://commons.wikimedia.org/wiki/File:MediaWiki_Performance_Profiling.ogv * Chris Steipp on security: https://commons.wikimedia.org/wiki/File:MediaWiki_Security.ogv * Ryan Lane on Puppet: https://commons.wikimedia.org/wiki/File:Puppet_Tutorial.ogv As a reminder, there are a number of previous tutorial videos online as well, e.g. from the Berlin hackathon and the SF hackathon earlier this year: https://commons.wikimedia.org/wiki/Category:Hackathon_Berlin_2012 https://commons.wikimedia.org/wiki/Category:Wikimedia_Hackathon_San_Francis… If anyone feels like doing some wiki-gnoming, it'd be nice to have more consistent categorization for all these videos on Commons, and perhaps a directory on MediaWiki.org if there isn't one already.
