The sorry state of ATI drivers in Linux

Subtitle: broken by impress.js

I've been using Linux as the primary OS on all my laptops since a loooong time ago and until recently I always chose computers fitted with nvidia graphics over any other brand because their drivers probably have the best quality and performance.

My last (and current) laptop, an HP ProBook, came with ATI graphics, but since in the last years ATI seemed to have caught up, I decided to give it a try.
For over two yeas the laptop performed extremely well with Ubuntu 10.04 LTS as everything worked right out of the box with no customization whatsoever. Suspend/resume worked, performance was great and boot time pretty good too (for a conventional hard drive at 7200rpm, at least). The problems came with the upgrade to Ubuntu 12.04.

Merry Christmas!

It's that time of the year again and, since it appears that the Maya spared us, I want to share with you a couple of gists that I came up with recently that could be generally useful. Btw, there are lots of other gists on my gist.github.com profile, check them out.

If you find these script useful star them on github, drop me a comment or just share them. Once again, Merry Christmas everyone!

The first one is for Java people and is a HttpServletRequestWrapper that supports:
  1. injection of the principal: for those cases when you use trust authentication and you are rolling your own SSO solution and/or you need to integrate with an existing SSO solution (I used it with for CAS)
  2. supports reading of the InputStream multiple times. We all know that in a POST the request input stream can only be read once, so this will definitely help you if you need to access the post body or a request parameter in a Filter and make sure the upstream servlets/filters still work
