Zunk writes “While traditional approaches essentially start with a “brain,” and attempt to build robots “downward” from that, BEAM robotics starts from simple reflexes, in a “bottoms-up” approach. The majority of BEAM robots are non-computerized (although simple CPUs can be used to drive them, in a “horse and rider” sort of way). Unlike many traditional processor-based robots, BEAM robots are cheap, simple, and can be built by a hobbyist with basic skills in a matter of hours. Because of this, BEAM is an excellent way of getting started in robotics, and of learning about electronics”. Link.
Wow, a Tablet Mac might be hitting the scene soon! Awhile back there were stories (2004) about a tablet Mac and today 
Here’s a great step-by-step on using Firefox, Greasemonkey and Flickr to GeoTag your photos to use with GeoBloggers.com. Once you get the script installed, you browse to your Flickr image, add a new “geotag” and enter in a zip code. You’ll then use Google maps to locate a position and it saves the location data to the photo. Once that’s complete you can submit the image to Geobloggers. 
On the BSD DevCenter Mikhail Zakharov has an article about installing NetBSD on an old Toshiba T2130CS- Intel 486DX4 75MHz notebook. The challenge was, with a lot of old hardware many of us have, is to install without the benefit of using a CD-ROM drive. With only the floppy drive and the LPT/COM ports, it’s usually tough to get anything on old machines. 
I was looking for something else, but then found this and figured it might come in handy for something- here’s how to control the parallel port with Perl using a module called Device:ParallelPort. Device::ParallelPort is a Perl API that allows low level access to the parallel port of most computers. It does this by using a number of drivers, which can be customized and added to, including Linux (direct and parport), Win32, Script, Dummy, and more. It also contains a number of direct access devices including an example printer and a relay controller card.
