For a few years now web developers around the world have celebrated Saturnalia Christmas with advent calendars covering topics related to the web. Some come and go, but you’ll probably recognize a few regulars on this list.
I may have missed some, so please pass them along if you know of any. As I learned in prior years where I have tracked them, I don’t know them all on December 1, and update accordingly. Some of this is because the sites don’t promote the new calendar on the home page.
UXmas is an advent calendar aimed at the user experience community. Coming from Australia, American readers may be thrown just a bit by the schedule. The calendar promises everything from sketches, to articles, to tools, to videos.
24 Pull Requests is less an advent calendar than it is an effort to mobilize developers. The goal is to get developers to send a pull request every day in December (up to Christmas), thereby supporting your favorite open source projects. There are even Coderwall badges for those who collect those sorts of things.
With the Webkrauts advent calendar not returning this year, Jens Grochtdreis (one of the Webkrauts organizers) will be doing his own advent calendar by presenting 24 CodePens (not necessarily his CodePens) that he has found interesting.
Performance Calendar hails this as the speed geek’s favorite time of the year, ostensibly because of the tips it has been offering each December since 2009. It isn’t just server optimizations you’ll find here, so don’t shy away because you’re not a system admin. While I had it listed last year, it hadn’t launched when I posted this. So I’ve rectified that.
SysAdvent is aimed at systems administrators, but there is a some cross-over to web developers. It has posts dating back to 2008, so there is plenty of good material there if you’re too impatient to wait for each day to be revealed.
Web Advent Calendar is a collection of posts from web designers and web developers primarily covering things that interest them. There is no overriding theme, so you can expect a lot of variety. There is also no set publishing schedule — on December 1, posts 1, 2, 4 and 10 were already published, though a couple have already been online for months.
The Content Strategy Advent Calendar is not a technical calendar but instead is focused on providing advice and tips on all things content related. Each day a new video will be revealed from a content strategy expert (sadly, as of the first day there are no closed captions).
13. Perl 6 Advent Calendar
Perl 6 Advent Calendar is conveniently timed with the anniversary of the first release of the Perl 6 specification. It will post something the authors like about Perl 6 each day.
Advent of Code provides a small programming puzzle every day up to Christmas. They are stand-alone, but supposedly have a general theme. They also use different technologies so there is some variety as well.
Grid by Example is a collection of CSS Grid examples by Rachel Andrew, though not exactly in advent format. Instead she is posting a new detail about Grid each day running up to Christmas. As such, I linked to the first post instead of a dedicated calendar page.
Remy Sharp, one of the names behind ffconf among other ventures, has his own advent calendar hosted on his blog. It is not a regular countdown advent, but instead daily postings that I am assuming will wrap up by Christmas.
20. QEMU Advent Calendar
The QEMU Advent Calendar provides a new QEMU disk image each day. For those unfamiliar (like me), QEMU is machine emulator / virtualizer that is also open source.
I started tracking these in 2010. Since then some have come and gone. For the ones not returning, in many cases the content is still out there. Take a look and maybe you’ll find an older article that is useful today.
