Some websites I have found interesting (in no particular order):
GeoIP — Simple and to the point, give it an IP Address and it will give you a pretty good guess for where in the world it correspondes to.
Lightweight Web Services — A talk about the Sinatra web framework and the RestClient library. I have been thinking how Rails doesn’t have anything like Django’s concept of Apps for breaking code up into smaller pieces. I think this is a great solution for Ruby.
Web design tools and resources I use — This is quite old, but I find it very interesting. One of these days I will make one of these myself.
92% Success Rate With New OpenID Method — Also quite old, this is great that it is so successful, but it seems to me that it comes at a cost: moving away from what makes OpenID great: simple single sign-on. This seems more like Facebook Connect, which is good because it could get people to use an alternative to Facebook’s propriety APIs but bad because I don’t really like Facebook Connect.
