Das Cherry Keypad G84-4700 ist ansich ein ganz normaler Ziffernblock, allerdings mit der kleinen Besonderheit, dass die Tasten programmierbar sind. Mit dem beiliegenden Cherry Windows-Treiber kann jede Taste beliebige Zeichenfolgen senden… Windows? Linux (in meinem Fall Ubuntu Desktop) wird von Cherry weder erwähnt, noch werden entsprechende Anfragen vom Support beantwortet. Doch die Verlockung auf zusätzliche Shortcuts war zu groß und so habe ich mir einfach das Keypad bestellt. (weiterlesen…)
I didn’t use any cloud storage service before, mostly because of security. I usually don’t really care about my data being that attractive to big companies, but didn’t feel well to have all my data stored in some unknown sky. Finally I tried Ubuntu One for one file not being worth to be stolen today. (weiterlesen…)
The YAWF framework is available from CPAN, but it still needs a Webserver and some environment for working at it’s best. This tutorial shows everything needed to set up a new OpenVZ VE (VServer) with MongoDB and YAWF framework on an existing OpenVZ host.
Just upgraded to Ubuntu 11.10!
Upgrade took ~3-5 hours (don’t know, download and installation were running in the background). First boot took some minutes, but it’s worth the time. A new login screen, no real problems – same as for the last Ubuntu upgrades.
Things that did not work after upgrade:
- Custom keybindings for changing the workspace
- Switch from Unity to classic interface, but new Unity looks better and I’ll try it again
- Ekiga SIP Softphone lost settings
- Pidgin icon in systray on new messages seems to be broken, but I have to test again
Things I expected to fail but working after upgrade:
- My local PostgreSQL test server upgraded from 8.4 to 9.1, I expected a manual conversion of the old database (like the upgrader/installer told me) – but everything is fine without manual interaction
- Truecrypt, VPN and my customer launcher script are working without any changes
Wer kennt das nicht, ein “grep -r” durchsucht nicht nur den gewünschten Quellcode, sondern auch gleich alle “.svn”-Verzeichnisse im Checkout. Um die nervigen unerwünschten Ergebnisse zu unterdrücken, reicht ein einmaliger Eintrag von
export GREP_OPTIONS="--exclude-dir=\.svn --color=auto"
in ~/.profile, ~/.bash_profile oder ~/.bashrc (je nachdem welche existiert und vom eigenen Linux verwendet wird).
Modern IT silently made some common problem go away: “No space left on device” became really rare during these days, but I started getting it last week when running some tests with huge data packages. My Ubuntu partition is 20 GB plus 8 GB swapspace and some more for a crypted data partition, but some 180 GB are still blocked by factory Windows 7 installed on this laptop. (weiterlesen…)
