remove safari’s resize grip in textareas

March 11, 2010

Another quickie: You know those resize grips that safari adds in to textarea input fields by default? Generally I find them helpful, but I was recently asked to remove them entirely from a website. Turns out it’s pretty easy to do, with some simple css: textarea { resize: none; } Cheers…

textmate and ruby 1.9 – Invalid multibyte char

March 3, 2010

If you’ve upgraded to ruby 1.9 (i’m currently on 1.9.1), and you use textmate, you might be getting slammed with these “invalid multibyte char” errors when running all kinds of commands.

SWIG vs libxen

February 17, 2010

SWIG is an awesome tool. I’ve been developing a lot in ruby recently, and I’ve often wanted to use features from external C or C++ libraries, but hated writing the wrapper code to make them available to ruby. Enter SWIG — the Simplified Wrapper and Interface Generator. It takes 99% of the burden off the [...]
