LinuxBIOS with X11 server, completely in Flash ROM

Now, this is one cool project (and video) from Alan Carvalho de Assis (and friends), as announced on the LinuxBIOS mailing list: LinuxBIOS with X Server Inside (YouTube video).

The setup: LinuxBIOS + a Linux kernel + BusyBox + a tiny X11 server (Kdrive) + the Matchbox window manager + rxvt.

All of this in a normal BIOS chip (2 MB), without any hard drive connected (who needs hard drives when you can fit everything in the BIOS just fine)...

The thing boots into BusyBox in less than 6 seconds, then in ca. 2 seconds into X11 + rxvt. There's probably even room for improvement there...

It seems there will be an OGG Theora version of the video soon, and I hope a small HOWTO about the project, too.

More LinuxBIOS-related screenshots and videos are available in the wiki btw., and a bunch more will follow soon...

LinuxBIOS talk video recording from FOSDEM 2007

Highly recommended for anybody who might be even remotely interested in LinuxBIOS:

There's a video recording (OGG, 234 MB) of the LinuxBIOS talk at FOSDEM 2007 by LinuxBIOS-founder Ron Minnich.

The talk is about LinuxBIOS, its history, how it works, what the main challenges are, where it's used today and what the future will likely hold. Watch it, you won't regret it.

And if you want to know more, or maybe even consider contributing, head over to linuxbios.org or contact the mailing list.

Capturing and replaying console/terminal sessions with script and scriptreplay

Have you ever wondered how you can easily capture a console session on Linux (and probably most other Unix-like OSes) without the need for special video recording software?

Here's how: you can use the script(1) command (part of the bsdutils package).

  • Start the script command. Without parameters the sessions will be logged to a file called typescript. You can also supply a filename on the command line: script mysession.log.
  • Type whatever you want to record...
  • End the recording session with exit or CTRL-d.
  • You can now view the file with less -r mysession.log (it contains line feeds, escape sequences etc., so a simple text viewer will probably display garbage). You can even print it with lpr(1). Or simply display it on the terminal with cat mysession.log.

An even cooler feature is that you can replay a script with the correct timing information:

  • First you have to also record the timing information using the -t switch: script -t 2>mysession.timing mysession.log.
  • You can then replay the script: scriptreplay mysession.timing mysession.log.

See the script(1) and scriptreplay(1) manpages for more details.

FOSDEM interview with LinuxBIOS founder Ronald G. Minnich

A few interesting interviews with speakers at the upcoming FOSDEM 2007 have been published.

I especially recommend reading the interview with Ronald G. Minnich, the founder of the LinuxBIOS project.

Here are the questions he was asked:

  • What's your goal for your talk at FOSDEM?
  • We saw the mention on the LinuxBIOS website about one million devices shipped with LinuxBIOS. Could you tell us more about these devices?
  • What kind of support have you received from chipset and motherboard manufacturers so far?
  • Could LinuxBIOS theoretically replace all BIOSes, of are there certain limitations to be taken into account?
  • Could you tell us a bit more about the BIOS side of the OLPC laptop?
  • What exactly is the difference between "easy" hardware to write a BIOS for, and the "tough" hardware?
  • What are your thoughts on the Extensible Firmware Interface (EFI)?

Linux Genuine Advantage (tm)

Linux Genuine Advantage™ is an exciting and mandatory new way for you to place your computer under the remote control of an untrusted third party!

According to an independent study conducted by some scientists, many users of Linux are running non-Genuine versions of their operating system. This puts them at the disadvantage of having their computers work normally, without periodically phoning home unannounced to see if it's OK for their computer to continue functioning. These users are also missing out on the Advantage of paying ongoing licensing fees to ensure their computer keeps operating properly.

[...]

Once you've installed Linux Genuine Advantage™, you'll want to register and send in your licensing fees to receive these important benefits:

  • Your computer, which worked just fine before, will continue functioning normally!
  • Our software which you just installed will not disable logins on your computer (as long as our license server keeps working properly)!
  • It's totally awesome!
  • We might not raise the yearly licensing fees in the future!

[...]

Did you wake up this morning and say "I wish someone would figure out a way to let me do less with my computer"? You've come to the right place!

Hilarious! They even got source code: http://www.linuxgenuineadvantage.org/source/.
