Ein Google Alert (… ja, ich lasse nach meiner selbst googlen, denn ich will ja wissen, wo ich überall auftauche…) trug heute was Erstaunliches in meine Inbox:
Moment… “Jean Pierre Wenzel aus Grub”? WTF?
Ein bisschen Surfen im Google Cache brachte dann das hier zum Vorschein:
Da möchte Partnerschaft.de wohl die eigene Link-Farm mit mehr Content füllen… Schade nur, dass das thematisch mal überhaupt gar nicht passt — es sei denn, wir ziehen alle schnell um oder gehen Partnerschaften mit unserem Boot-Loader ein… 
P.S. Da die Frage gleich aufkam: Die hinreichende Schöpfungshöhe ist bei Tweets wohl nicht erreicht, daher sieht die urheberrechtliche Handhabe eher mau aus, sollte jemand sich durch die Verwendung seiner Tweets auf den Schlips getreten fühlen.

Ich liebe ja humorvolle Fehlermeldungen:
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
missing codepage or helper program, or other error
Manchmal liefert das Syslog wertvolle Informationen – versuchen
Sie dmesg | tail oder so
(Quelle: mount, Ubuntu 8.04 LTS)
Geholfen hat’s leider nichts, scheinbar wird das Dateisystem auf der verwendeten DVD-RAM nicht korrekt erzeugt. mkudffs läuft zwar ohne Fehler durch, aber das Dateisystem kann ich dann trotzdem nicht einhängen. Vermutlich ist dann doch einfach die Scheibe defekt. Da es sich um ein off-site System handelt, kann ich aber leider nicht mal eben nachschauen. Das muss dann wohl bis morgen warten.

First I get this automatic e-mail notification this morning:
Fr 13. Feb 03:07:15 CET 2009
Writing of backup […] to media […] failed.
And then… I read my fortune cookie for the day:
What happened last night can happen again.
Oh, and I forgot. I’m not superstitious, but the calendar says today is Friday, 13th…

Adobe makes a good job of promoting its new version of their Flash Player 10. They seem to have removed almost every single link to the previous version on their website and all old links redirect to the download of version 10.
This might be great if you want to run their latest software, but if for some reason you need a specific older version, you’re gonna be quite upset, e.g., you want Flash on a legacy operating system such as Windows 98/ME, Mac OS X < 10.4, or older Linux/UNIX OSes.
In my case, there is a web site that has been programmed in such a bad way that it is simply broken and unusuable with the latest version of Flash Player 10. I don’t use the service of that website on a daily basis, but I wanted to install Flash Player 9 on top of a Windows installation in a VM.
You can find the installation files for the legacy Flash Player 9 download on Adobe’s TechNote site. Please keep in mind that Adobe may (and surely will) stop releasing any [security] updates for those old versions of Flash.
Of course–after I eventually found the download link and installed the old Flash version–I remembered having a moldy Ubuntu Live DVD somewhere in my drawer… And I bet it has Flash Player 8 or 9 installed…

No, not me. Not again. At least not yet.
We’ll be moving our external web and mail server to a different (more powerful) physical machine because the current setup is under quite some load. Thanks, f***ing spammers. Ten thousands of spam mails to check every day (and that’s only the amount of mails that passed the first pitfalls on the way to talking to the mail server) is a little be too much for our small server. Hopefully it’s getting better on the upgraded hardware with some tweaking here and there.
Moving will be performed within the next days during night hours in Europe so you might experience some glitches. Apologies in advance for any inconvenience.

As some of you still using Ubuntu 6.10 (“Edgy Eft”) might have noticed, there are no updates for this available anymore. The corresponding package folders are missing on the Ubuntu mirrors and apt/aptitude updates result in a lot of HTTP 404 errors. In case you missed the news, you can still read the End of Life announcement for Edgy.
So, to cut a long story short: you’re still stuck with your legacy Ubuntu version and want to upgrade it. Unfortunately, Update Manager fails because it wants to check the (non-existant) Edgy branch of the Ubuntu apt repository for Edgy updates prior to upgrading to the new version.
The solution (only for the brave ones) is to change the apt sources and perform the update manually.
$ sudo sed -e 's/\sedgy/ feisty/g' -i /etc/apt/sources.list
Following the Feisty upgrade instructions, run these commands:
$ sudo aptitude update && sudo aptitude dist-upgrade && sudo aptitude dist-upgrade
$ sudo aptitude update && sudo aptitude dist-upgrade
$ sudo aptitude -f install
$ sudo dpkg --configure -a
Fix any upcoming errors, so that eventually invoking the sudo aptitude update && sudo aptitude dist-upgrade will show no additional updates to be installed and also displays no errors.
After rebooting to let the kernel update become effective, you should have successfully upgraded to Ubuntu 7.04 (“Feisty Fawn”) which life cycle will end in October 2008. It might be a good idea to consider an upgrade to Ubuntu 7.10 (“Gutsy Gibbon”) or even upgrading to Ubuntu 8.04 LTS (“Hardy Heron”) right away.

Just as a reminder for myself…
Of course, the new company laptop came with a Windows installation, but setting up Ubuntu was far more straight forward than when I tried Fedora Core on a Toshiba Satellite M30 years ago. Although the installation instructions linked above cover the T61, most of them also work for the Lenovo Thinkpad R61.

Almost three years ago I discovered that apt has Super Cow Powers.
Recent Debian-based Linux distributions like Ubuntu favour aptitude over apt because (among other reasons) of its capability of automagically removing unneeded packages.
Well, aptitude doesn’t come with super powers, but it also has an easter egg as can be seen on a screenshot taken by OSSblogger.com.

If you only need to run VMware images (e.g. provided by your professor), you might want to try out the free VMware Player software. Works great (after applying the VMware any-any patch and compiling your own kernel modules [remember to have the kernel-devel package installed]).
If you decide to create your own virtual machine, e.g. to run a Windows OS inside a sandbox within your safe FC5 environment, VMware offers a VMware Server Beta free of charge. You just have to register and will get a serial number sent to your e-mail address.
Install as you like (you can install the provided RPM files using rpm -ivh ... or untar/un-gzip the tar.gz archives) and run the configuration scripts provided with the packages. A good installation guide can be found on VMware Support website.
After the installation and a reboot I had trouble connecting to the server. I found this hint on the VMware forum and -surprise- the error is caused by SELinux (I’m really thinking about simply disabling it!)
Run these commands (as root) to configure SELinux properly:
# find /usr/lib/vmware -name '*.so*' -exec chcon -t texrel_shlib_t {} \;
# rm /var/run/vmware/vmware-serverd.PID
Now you should be able to connect again to your VMware server.
