Ubuntu 14.04 Trusty: Mapping USB keyboards

I bought a Cherry G84-4700PUCDE-2 keypad about three years ago to have some "special multimedia keys" on the left side of my keyboard. It used to work after some trying until I upgraded to Ubuntu 14.04. The "trusty" release removed support for /lib/udev/findkeys and /lib/udev/keymap and replaced both by something called "hwdb". Converting turned out to be hard, because there are many wrong hints out there spread over the internet.

Speed up RAID5/RAID6 write speed

I'm currently upgrading from Ubuntu 9.04 to Ubuntu 12.04, a long process as every upgrade does only one step. This is the price you pay for skipping all updates of the last years. It's even slower since I moved my root filesystem to a RAID6.

End tag mismatch - MovableType WordPress Import

I tried MovableType just before setting up WordPress for this blog. It didn't offer the features I wanted (okay, WordPress still doesn't have them, but it promised to have them and so it won). After trying out MT again, I want to have it. But what about my existing articles, comments, settings? That's (the only reason) why I'm still using WordPress.

CRON: User account has expired

Recently, I discovered strange messages in a servers system log. The cron daemon was complaining about an expired user account, but there are no user accounts on this server, which should ever expire.

Apache2 mit PHP5-FPM und chroot-Jail

Seit einiger Zeit arbeite ich mit PSGI/Plack, aber erst jetzt weiß ich, wie schön Plackup, Starman & Co. wirklich sind - denn heute wollte ich "mal eben" PHP5 in eine FastCGI-Umgebung schieben. Dafür gibt es den PHP-FPM (FastCGI Process Manager), der mittlerweile wie auch alles andere was nur wenige Leute brauchen Teil des PHP-Core ist und dieser unterstützt sogar die Absicherung der PHP-Scripte mittels chroot - allerdings habe ich keine Anleitung im Internet gefunden, die dieses wichtige Security-Feature tatsächlich nutzt.

Add custom items to Ubuntu NM dnsmasq.conf

The Ubuntu NetworkManager (NM) is great (exept for servers), it's taking care of all network issues up to VPN. NM supports using multiple network connections with multiple DNS servers and probably multiple private domains by running a local DNSmasq process which will forward all lookup requests to the proper nameserver. But the NM is new and still missing some feature - like additional or custom configuration lines for DNSmasq.

Google Drive / Google Docs icon in Ubuntu Unity Starter

I like Google Docs (which is now Google Drive, but I rarely use it as a cloud drive), but Opera and Google Docs aren't good friends and Chrome seems to be the only best browser to use Google's "online office". I like Opera and have no reason switching to Chrome except docs.

Ubuntu Network Manager in der Shell bedienen

Ja, ich gestehe, ich stamme aus DOS-Zeiten. Ursprünglich DATAPOINT-DOS auf einem 6600 und später MS-DOS auf dem PC. Bis heute bin ich kein echter GUI-User geworden, sondern arbeite viel mit Scripten und Shell-Fenstern. Seit etwa einem halben Jahr suche ich nach einer Möglichkeit, den Ubuntu NetworkManager per Skript zu kontrollieren, genauer gesagt eine Verbindung auf- oder abzubauen.

Free storage: Ubuntu One

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.

Ubuntu 11.10 upgrade

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

SVN-Verzeichnisse beim grep'en ignorieren

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).

Shrink NTFS partition and claim the free space for Linux/Ubuntu

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.
