July 8, 2010I always struggled at reviewing code. Specially when the code to be reviewed is in reality a patch inlined in some e-mail… I hate monospaced fonts in my e-mail reader, and with all the context switches I got in my daily work, I simply can’t concentrate properly in order to follow what’s been proposed with [...]

Cedilla (ç) symbol using American Keyboards in Linux
November 5, 2008Disclaimer: this article refers to using Linux with an American keyboard to type Portuguese (pt-br) text, using the ‘us-intl’ keyboard layout. One of the things that bothered me when upgrading between Ubuntu versions a while back (Feisty for Gutsy? Hardy? I can’t remember) is the changed behavior for inputting the Cedilla ‘ç’ symbol using American [...]
