Verify existing files using a torrent
I just had a nice (btrfs related) crash while copying some finished torrents to my primary workstation (and file vault). The crash happened (of course) just after i've deleted the files from the source server but was soon enough to cause corruption as most of the data was still stored on RAM :-/
So i've hacked a small tool called torrent-tool (download at github) How does it work You can use the --show parameter to check an existing torrent file: $ ./torre...

Changing the stylus pressure on a technics sl-7 turntable
published at Sun Sep 25 17:46:27 2011 in misc
I own an old Technics SL-7 and was (until recently) not smart enough to change the stylus pressure — even after reading the manual (you can download the sl-7 manual from here btw...)
The magic screw is located on the right side (the location in the manual is therefore completly wrong ;-) )
and the pressure can be changed by ±0.25g:

The Economist cache
published at Fri Sep 23 09:41:14 2011 in android
The Economist provides a nice Android application, however: the cache contents (saved on the sd-card by the application) are 'encrypted' for some silly reason.
We will fix that within a few minutes.
Analyzing the data
The 'encrypted' data is stored at /your/phone/com.economist/library/$date, let us have a look at some cached files:

6RD (IPv6) via Bluewin/Swisscom DSL

6RD (IPv6) via Bluewin/Swisscom DSL
Seit Mitte 2011 bietet die Swisscom (bzw. ex Bluewin) einen 6RD gateway an. (Siehe http://labs.swisscom.ch/en/node/692/).
Der 6rd-tunnel scheint aus allen Bluewin-IP-Ranges erreichbar zu sein, folglich muss man nur die IP des 'Gateways' (6rd.bluewin.ch / 6rd.swisscom.com - 193.5.122.254, bzw. 164.128.155.23 bis zum 8. November 2011) und den Prefix der Swisscom (2a02:1200::/28) wissen:
Mit diesen Angaben lässt sich 6rd problemlos auf einem halbwegs aktuellen Linuxr...» Read 8711 more bytes
Ejabberd clustering
published at Tue Aug 23 15:45:32 2011 in linux
Some notes about ejabberd clustering (incomplete and probably wrong ;-) )
Setup the first node
Note: If you are already running a single ejabberd node (called ejabberd@localhost) i'd recommend to simply dump mnesia and import it again: changing the node name might be too much work
We will call the first node ejabberd@first.example.com
Install erlang and ejabberd Create your ejabberd.cfg file In ejabberdctl.cfg: set INET_DIST_INTERFACE={10,0,0,1} (where 10.0.0.1 is the ip of first.example.co...

published at Sun Mar 20 16:21:06 2011 in android
Installing custom ROMs on a HTC Legend device running Android 2.2.x is a real pain but it can be done.
You'll need:
A HTC Legend running HTCs Froyo (Android 2.2) image Some PC running Windows (sorry!) [you also need to install the android SDK] Some leaked HTC Software (google) 2 Micro SD-Cards (using one would work, but having two makes it easier
Some Notes This will void your warranty Blabla.. insert standard disclaimer here I didn't do any of the fancy stuff: this is just a collection...

MythTV Autoshutdown/Poweron
Wer sein MythTV Backend (+ Frontend) im Wohnzimmer stehen hat, möchte die Kiste wohl kaum
7x24h am rumrödeln haben. Abstellen ist ja kein problem, aber wie kommt die Kiste von alleine wieder hoch? Eigentlich kein problem, man
muss nur etwas rumbastelnt :-) [...und das ist der MythTV User ja gewohnt ;-) ]

SixAxis / Dualshock 3 und Linux
Sony verkauft mit dem SixAxis-Controller ein ganz nettes Bluetoot-Gamepad welches sich
super für SNES-Emulatoren eignet. (Klar: Man hat ja damals auch das Design geklaut.)
System vorbereiten
Auf http://www.pabr.org/sixlinux/sixlinux.en.html ist eigentlich alles ganz prima erklärt, damit ich aber auch was zum schreiben habe:
hier die Kurzversion:hidd patchen Der Controller wird out-of-the-box nicht funktionieren: Zuerst muss hidd (bluez-utils) gepatcht und...
