I was looking forward to today (despite it being a Monday, and a hectic application release this morning), as it is the first of December.
Which means that it's time to start visiting http://24ways.org/ again.
24ways is basically an advent calendar for geeks. Every day a new article is added, complete with source code (where relevant), and has often provided some great resources for me over the years.
I found this site in 2005 when it started, and have made it part of my daily December routine to check out every year. Forget your chocolate-filled advent calendar (if you want to put on weight over December, just check out my previous post), and look at http://24ways.org/ instead.
