  CSS Rounded Corners In All Browsers (With No Images)

In the past two years, increased browser support has transformed CSS3 from a fringe activity for Safari geeks to a viable option for enterprise level websites.

  Some Thoughts on Twitter's Availability Problems

As a regular user of Twitter I've felt the waves of frustration wash over me these past couple of weeks as the service has been hit by one outage after another. This led me to start pondering the problem space [especially as it relates to what I'm currently working on at work] and deduce that the service must have some serious architectural flaws which have nothing to do with the reason usually thrown about by non-technical pundits (i.e. Ruby on Rails is to blame).
