As in year’s past, several tech communities are running Advent calendars during the month of December:
- Perf Planet Advent (performance) – RSS
- 24ways Advent (web design/development) – RSS
- Perl Advent (Perl language) – RSS
- Web Advent (web development, formerly PHP Advent) – RSS
- AWS Advent (Amazon Web Services tips & tricks) – RSS
- HTML and CSS Advent (Digitpaint HTML & CSS) – RSS
I have a combined RSS feed (created with Yahoo! Pipes) that picks up all of these advent calendars: http://feeds.feedburner.com/TechAdventCalendars. (Yahoo Pipe source).
