Snake@youtube and geek and sundry promo

April 21st, 2013 No comments

Willi wrote a line or two about an all-time classic: Snake. And by incident, I currently discovered that Youtube has a build-in Snake game. Just press the arrow keys while the video is loading/buffering (the circle of circles, you know…).
So have fun by clicking the video now and playing snake 🙂

PS: I’d also like to take the chance to promote the Geek and Sundry Channel on Youtube!

Recovering microSD under Ubuntu (12.04), should work on other Linuxes

January 28th, 2013 5 comments

My Android phone somehow managed to kill the inserted 32 GB microSD card, which is really annoying as I have most of my applications on this card and – which is much worse – photos taken at several occasions.

When I connected the card (via an SD-microSD adapter), Ubuntu told me “mount: /dev/sdb1: can’t read superblock” (obviously trying to mount it as ext).  Forcing Linux to mount the card as FAT didn’t work either, so I googled somewhat and found a tool called TestDisk!

TestDisk allows to recover lost data and this is what I did to get most of my content back

  1. sudo apt-get install testdisk
  2. sudo testdisk
  3. [Create] create a new log file
  4. Select /dev/sdb (“…FlashMedia”) and Proceed
  5. Select [Intel] Intel/PC partition
  6. (Backup, just in case sth happens)  [Advanced] -> [Image Creation] -> Select target Folder
  7. [Analyze]->[Quick Search]
  8. [Enter to continue]
  9. [Deeper Search]
  10. [P] (list files)
  11. [A] (select all files, which includes folders)
  12. [C] Copy files
  13. select target folder
  14. [C] (copy to selected folder)

And thats it 🙂 Whee!!!!

Finde den Fehler (3)

June 12th, 2012 8 comments

Heute wieder eine Fehlersuche (nach langer Pause)
Diesmal präsentiert von (IT News für Profis)

Dabei sind die logischen Kerne 0 und 1 den Rechenwerken auf demselben realen Core zugeordnet. Ein Dual-Core mit Hyperthreading verfügt so aus Sicht des Betriebssystems über die Kerne 0, 1, 2 und 3. Wenn nun beispielsweise ein Programm drei Threads ausführt, werden diese am besten auf den Kernen 0 und 2 sowie einem der beiden Cores 1 oder 3 bearbeitet. Die Kombination 0, 1, 3 ist dagegen ungünstig, weil so zwei Threads auf virtuellen Kernen laufen.

Diese Woche in Dresden

May 30th, 2011 No comments

Ich möchte nochmal auf zwei Religionsveranstaltungen diese Woche in Dresden hinweisen.
Wohingegen der evangelische Kirchentag unter dem Motto “Da wird auch Dein Herz sein” (Matthaeus 6, 21, Elberfelder Bibel)
schon relativ bekannt ist, feiern die “Atheisten” von GeFAHR e.V. unter dem Motto “Und da wird Dein Hirn sein” zur gleichen Zeit die religionsfreie Zone in Dresden.
Egal, wo ihr hingeht – Viel Spaß!

Kinderarbeit und so

Sorry an die unpolitischen Leser für die Politikposts, aber dass die Initiative Neue Soziale Marktwirtschaft endlich anzeigt, worauf ihre Politik hinausläuft finde ich erstaunlich.

Update: (Das Kleingedruckte beim Link könnt ihr gern überlesen)

Lego collectible minifigs (2)

January 7th, 2011 1 comment

So here it is, series 3 has landed in Dresden (Karstadt), other sales markets will get their deliveries soon.
And nope, no bar code anywhere, but little bumps (dots which poke out) and some wells (dots poking out to the other side) on the back of the package.
And unfortunately, the dot-pattern differs from the one they seem to use in the United States 🙁
Here are the patterns for the figures I bought today. White circle means out-poking dots and wells are black.
Update: I’ve been in another store yesterday and it seems, that the direction of the bump might vary. So you should only look for their location.

Samurai:Lego Samurai dot-pattern
Mummy: Lego Mummy dot-pattern
Gorilla suit: Lego Gorilla dot-pattern
Elf: Lego Elf dot-pattern
(No warranty that the dot-pattern is valid elsewhere)

Diesmal ist es nicht ganz so einfach, wie das letzte Mal, aber eigentlich immer noch offensichtlich. Zu gewinnen gibt es wie immer nichts außer den Ruhm Erster zu sein. “Sponsor” ist diesmal “Die Bahn” und jetzt geht es schon los:

Wo ist der Fehler?

Da ist sogar noch ein zweiter Fehler erkennbar. Viel Spaß beim Suchen

One-liner pin shell and processes

November 26th, 2010 No comments

There’s no rocket science content in this post. It’s just something I use often and don’t want to forget.
If you want to pin a shell and all prospectively started processes to a specific subset of cpus execute:

taskset -pc `echo $$` <cpu-list>

Not only that it limits intererences between processes (user 1 might work on node 1, user 2 on node 2), it can also help increase energy efficiency. If all background threads are pinned on a single processor-core, other cores can be send to sleep for a longer time period, which allows higher C-states.

Update: Added <cpu-list>

NFS Remote I/O error after dist upgrade to Ubuntu 10.10

November 1st, 2010 7 comments

Ubuntu 10.10 uses NFS 4 by default. If you did not update your NFS-Server, while upgrading your client, you’ll receive a Remote I/O error, due to incompatibilities between version 3 and version 4. Change the mount options in your /etc/fstab from defaults to vers=3,defaults to prevent this error.
