How to compile TV output into the latest X.org ati drivers on Ubuntu

The Problem

You have built a home server slash PVR that you want to hook up to your twenty-year-old television. You have gone to several shops to buy a graphics card that actually has open-source drivers for its TV output functionality (i.e., the ATI Radeon A9250). You have dodged salesmen trying to sell you something else (“No, but here is its successor the NVidia so-and-so.” “Uhm, no thanks.”). You finally succeeded by ordering it over the Interweb (and probably should have done that in the first place). Now you want to patch the driver shipped by Ubuntu to actually get TV output working.

How to trim spaces in TeX

Posted by matijs Thu, 20 Jul 2006 19:27:00 GMT

The problem

You created a macro package for LaTeX and promised that people could write either

\synttree[ a label ]

or

\synttree[a label]

and the result would be the same. Now your buggy macro for trimming spaces stands in the way of a much needed bug fix.

In short, you need a macro \trim that will trim (The name says it all, doesn’t it?) spaces off of its argument’s beginning and end.
