Ubuntu Repository Crash-course

[Alan] has just posted an Ubuntu screencast that will take you through a crash course in the Ubuntu repositories. If you are new to Ubuntu this will give you a much better grasp on how software repositories are handled.

The different types of updates are discussed: Security updates fix bugs that cause a system vulnerability. Updates (generic) are for bug fixes that aren’t a security threat. Proposed updates are for testing before an update hits the ‘updates’ section. Finally, backports are updates from a newer version that have been ‘backported‘ so systems running older versions of Ubuntu can have the benefit of newer features and fixed bugs.

He also provides some tips on selecting package sources (main, universe, restricted, and multiverse), and choosing the fastest mirror to reduce download times. This screencast is just part one and we hope to see 3rd party repositories, personal package archives, and repository caching covered in future installments.

The devs over at the Fedora Project are hard at work on the development version: Rawhide. They’ve just setup automated nightly builds of the liveCD which can easily be downloaded and tested on a CD, DVD, USB drive, virtual machine, or separate partition.

Rawhide will be released as Fedora 12 upon completion.  With this version you have a choice of Gnome 2.28 or KDE 4.3 for your desktop.  There is also improved power management, expanded support for mobile broadband, easy bug reporting, and many more new or improved features. So roll up your sleeves, download last night’s build, and help test some open source software.

Embedded Linux Billy Bass

linux billy bass
if you haven’t seen this project before, it’s well worth a look.  the author shows us how to control billy from a pc104 embedded pc running linux.  included is an introduction into using open source tools for creating audio transcriptions, which can then be used to make billy lip-sync to custom audio clips.

the software controls the bass via the pc’s parallel port.  if you are interested in doing something like this, you might also want to check out the article we recently posted on controlling an r/c car from your parallel port.

toy hacks and controlling devices from your pc are really great topics.  i’d love to see more hacks like this.  make sure to send in your tips!

High Altitude Linux Weather Balloon

weather balloon

“i found it in my cow pasture, buried in the snow. i was riding my 4 wheeler.”  that’s what the postcard said when it returned to me after i sent it up with a helium balloon a couple weeks ago.  it traveled roughly 100 miles.

but i digress.

james meehan’s story began quite similarly, but he decided to take his balloon fascination to a much more fascinating and hackerly level.  follow the link to read about how he designed and constructed his linux powered weather balloon, complete with gps, packet radio uplink, and video camera.  he says it’s the coolest thing he’s ever done.  i can’t really vouch for what else he’s done, but this project is pretty darn cool.

when you’ve finished marvelling at this hack, make sure to also check out the home brew, high altitude glider we wrote about a while back.  i love this high altitude mischief.  if you know of similar projects, send ’em in!
