A year ago I received an OLPC XO (the “$100 laptop”) through their Give One Get One program. I played with it for a few days and found it essentially useless due to unstable and slow software (and lack of WPA support), so it quickly began gathering dust on a shelf (it has since improved).

The Amazon documentation for using S3 with PHP refers to an elusive function called “setAuthorizationHeader”. It’s apparently supposed to magically set the correct value for the Authorization header on a Pear HTTP_Request object.

Back at MacHack 2003 Jonathan Rentzsch talked about how to override functions and inject code in Mac OS X using several neat tricks. He also released a framework called mach_star which has two components: mach_override and mach_inject. These are great, but overkill for some simple cases.

Perhaps my favorite moment of the conference was when DEF CON organizer Jeff Moss lured Michelle Madigan, the undercover NBC [...]
As suggested by my friend and SCEC coworker Kevin Milner, I finally installed the GNU/Linux based OpenWRT replacement firmware on my house’s Linksys WRT54GL wireless router tonight. It gives you a minimal Linux distribution with most of the features of the WRT54GL’s original firmware built in, plus the ability to add a whole lot more.
