If you ever stumble upon the error message Error 17: Cannot mount selected partition
while attempting to install GRUB, do take a look at the partition table of the disk you're using, as the partition type in the table may not match the actual file system of the partition. While the Linux kernel doesn't pay much attention to the partition type, GRUB does - and fails with the above message.
This happened to me while trying to install a system to boot off an USB stick, where I forgot to edit the partition table types.

Our brand-spanking-new 4-way server has arrived today - just in time for Feisty! It's quite a fortunate coincidence, since if it had arrived here yesterday I might have gone with Etch. I'm currently waiting for the CD-Writer to finish, which for some reason has dropped the writing speed to 12x apparently just to spite me on this single occasion - hell, the download was faster than that!
Speaking of speeds, I'm currently seeding for the i386 and the amd64 versions of Ubuntu Server 7.04 ISOs, and it has struck me that the amd64 ISO uses on average 1.2 times the bandwidth of the i386 ISO; I had the impression that amd64 wasn't in that widespread use in the server domain.
P.S. The new server thinks that it's a vacuum cleaner...
P.P.S. The CD was borken, need to burn another - gah!

Two things have been keeping me quite busy the last six weeks: I'm now
properly employed, and I got married on September 16th!
To be honest, the marriage thing has taken a lot more time and energy than
we expected - at one time I joked that my vacations really started when my
2-week leave ended - but in the end it was all worth it. Expect photos to be
available on our
wedding blog sometime this week. The
last week we've been recovering from the party, and I've only now got some
courage up to write about it...
On another side, I'm now a full-time emnployee of
Aristotle University, where I'm partially the
sysadmin for a computer room/lab for students (oh, the joys of Windows
systems). This also means that I can expect to retire as a public servant,
holding the same position for the next 30 years (and doing the same stuff,
too...).

Infoworld reports that the Nigerian government will buy one million OLPC machines. Unfortunately, the first thing that comes to mind is the proliferation of 419 scams that will flood the internet in 2-3 years...
On another note, it seems that there is also some traction in Greece for the OLPC concept, as seen in this call for participation.

Quick: how long is the shortest program to calculate the first prime number
after a given number? The answer might surprise you!
In perl, it's about 60 characters:
perl -e '$i=$ARGV[0]+1;$i++while("."x$i)=~/^(..+?)\1+$/;print"$i\n";'
90
Of course, I believe
APL will
win that contest hands down...
P.S: There's even a perl competition to produce the shortest code for a
given problem, with the name
Perl Golf...

Wherein I reference a secretive little game of five dice, which is more of a puzzle than a game.
The name of the game is, predictably enough, Petals Around the Rose and it is played with five six-sided dice.
The name of the game is Petals Around the Rose, and that name is significant. Newcomers to the game can be told that much. They can also be told that every answer is zero or an even number. They can also be told the answer for every throw of the dice that are used in the game. And that's all the information they get.
Nifty, huh? You can view a more detailed explanation-cum-story, including answers, here. And there are several sites where you can play it online. Myself, it took me about 30 minutes spread out over 5 hours of work to figure it out. Of course, now I'm sworn to secrecy too, and cannot say anything more than the above...
