Over at http://fepus.net/ruby1line.txt you can find an awesome collection of ruby 1-liners. Here are some samples:
# align all text flush right on a 79-column width
    $  ruby -ne 'printf("%79s", $_)' < file.txt

# center all text in middle of 79-column width
    $  ruby -ne 'puts $_.chomp.center(79)' < file.txt
    $  ruby -lne 'puts $_.center(79)' < file.txt

# substitute (find and replace) "foo" with "bar" on each line
    $  ruby -pe 'gsub(/foo/, "bar")' < file.txt

# substitute "foo" with "bar" ONLY for lines which contain "baz"
    $  ruby -pe 'gsub(/foo/, "bar") if $_ = /baz/' < file.txt

# substitute "foo" with "bar" EXCEPT for lines which contain "baz"

$ ruby -pe ‘gsub(/foo/, “bar”;) unless $_ =~ /baz/‘ < file.txt

still not working for me…

If you end up getting this error message:

The path "/usr/src/linux/include"; is a kernel header file directory, but it
does not contain the file "linux/version.h"; as expected. This can happen if
the kernel has never been built, or if you have invoked the "make mrproper";
command in your kernel directory. In any case, you may want to rebuild your

Install kernel headers via:
sudo apt-get install linux-headers-`uname -r`

Do this (get YOUR_KERNEL_VERSION by doing uname -r):
# cd /usr/src/kernels/YOUR_KERNEL_VERSION/include/linux

  1. cp utsrelease.h version.h

and it should work :)

Woohoo, my Macbooks internal HDD (Hitachi Deathstar… oh… I'm sorry… Hitachi Deskstar) somehow broke. While browsing the net, everyhing froze and I had to reboot. Rebooting resultet in a "couldn't read yadda yadda"; message after 20 seconds and nothing happened after that, it just looped.

It wasn't a headcrash, it was just… well… I don't really know what it was, something broke and I'll get a new HDD :).

Anywhoooooo, luckily I've got a nice 750 GB HDD on my Airport Extreme which my macbook pushed Timemachine backups to until the bitter end. I used the backup made 2 hours before the disc went down the crapper and restored it on a 60 GB 2,5" SATA disc I still had in an external enclosure (1,3 GB of the 60 GB are still free).

What can I say, everything worked 0_o

I'm still searching for things that don't work, but so far, everything is there. The only thing that's missing is the Spotlight-index which is being rebuilt as we speak (wouldn't make any sense backing the index up anyway…)

presented at the Library of Congress, June 23rd 2008. This was tons of fun to present. I decided to forgo the PowerPoint and instead worked with students to prepare over 40 minutes of video for the 55 minute presentation. This is the result.
