Dropbox referrals / Dropbox rocks

I am using Dropbox for two years but just now I see the nice referral feature where you can get up to 8GB(!!!) of additional space by inviting people to use Dropbox. You get 250MB for each successful invite including installation of the Dropbox account.

Get 250MB additional space on Dropox using this link:

By the way: if you finish the 5 of 6 tasks under the “Get started” tab on the dropbox homepage you get additional 250MB.

Linux XFS Filesystem defragmentieren

XFS muss leider auch defragmentiert werden, gerade wenn das Filesystem sehr voll ist werden Dateien stark fragmentiert. Mit folgenden Kommandos kann man Abhilfe schaffen:

Check fragmentation of a file system:
sudo xfs_db -c frag -r /dev/mapper/[device]

Defrag a file system:
sudo xfs_fsr /dev/mapper/[device] -v

  • wer ist der Kunde für diese Aufgabe

Story/Aufgabe schreiben

  • Anforderungen zur Story zusammenfassen
  • Kunden/Anforderer zur Story hinzuschreiben
  • Welche Test und Abnahmekriterien sind bekannt, als Hinweis zur Story aufschreiben

Planning: Fragen ans Team

  • ist das Ziel/der Wert der Story klar
  • sind alle Grenzbedingungen bekannt/beachtet
  • was kann verändert werden, um fachlich ein besseres Ergebnis zu bekommen
  • wie kann es möglichst einfach und billig implementiert werden
  • was fehlt

Story/Aufgabe im Sprint

  • immer eine Vorbesprechung vor Start der ersten Aufgabe
  • bei Fragen und Problemen lieber einmal mehr sprechen
  • welche Folgeaufgaben sind zu erkennen

LVM + XFS resize Linux


become root

sudo bash

extend /dev/vg/home by 10 Gigabyte

lvextend -L+10G /dev/vg/home

grow the XFS filesystem for home. Note use the mount point for XFS

xfs_growfs /home

Moved to tumblr

I am rethinking my Webspace. Right now am barely using my private site so I decided to delete my private webspace with bluehost and move everything to a free service. All Posts are imported, only the comments cannot be imported so all comments are truncated.

I will add the BrutefirDRC manual pages within the next days and start to change the plugin and all links to my new site.

BrutefirDRC 1.2.0 released: now supporting all sample and bitrates

The new release 1.2.0 of BrutefirDRC is out! Features:

  • supporting audio files with different samplerate and different bitrates (thanks to Toby again, he changed the wrapper script to make this possible)
  • The user can define a directory with his own custom-convert Template files to be used when enabling the plugin
  • The PCM conversion has been deleted because FLAC is doing the job equally well
Bitrate and samplingrate The support for all sample and bitrates has been implemented by Toby. The brutefirwrapper now uses WAV as input and output format. The wrapper script can read the samplerate from the WAV header and resample the underyling filters as needed. For this to work all conversion templates have been changed to transcode input files to WAV in 24bit format. Tested formats known to work:
  • Flac with a bitrate of 16/24bit and a samplerate of 41000,48000 or 96000
  • MP3 with a samplerate of 41000 or 48000 (mp3 does not support samplerates of 96000)
  • OGG with a samplerate of 41000,48000 or 96000
  • WAV with a bitrate of 16/24bit and a samplerate of 41000,48000 or 96000
Tested formats that are not working on my installation (Ubuntu 9.10 with SqueezeBoxServer version: 7.4.1 - r28947 @ Tue Oct 20 07:58:02 PDT 2009):
  • AIFF all sampling and bitratess
  • WMA (no WMA-Decoder is included in the installation, so it cannot be transcoded to WAV)
All other formats have not been tested. Installation After replacing the old Plugin with the new version you need to
  • enable BrutefirDRC for all players that are using it
  • change your Brutefir Config-Files to use 24bit input (from sample: “S16_LE”; to sample: “S24_LE”;)!! See the example configuration files in filter_examples_1.2.0.tar.gz

Fix release of BrutefirDRC for Squeezeboxserver 7.4.0

The new version 1.1.1 of brutfirDRC works with the stable release of Squeezeboxserver 7.4.0 from Slimdevices. It only contains a small fix to work with the slightly different API of the new release, thanks to Michael Amster to help fixing the issue. Just download the new version from Sourceforge. Note that it is only tested with the current stable version 7.4.0. By the way: a few warnings are logged to the squezzeboxserver log, just ignore them for now. I am going to use the non deprecated versions of the mentioned functions in the next release. A few things to keep in mind when updating:

  1. The plugin directory for BrutefirDRC must be read and writeable for the squeezeboxcenter process
  2. Change the preferences of BrutefirDRC to use the new path to your filters and settings, if you changed them
  3. Change the filter files to use the new path if you moved them: i.e. my filters have been changed to “filename: “/etc/squeezeboxserver/BrutefirDrc/filters/filtername.pcm”; from “filename: “/etc/squeezecenter/BrutefirDrc/filters/filtername.pcm”;” The filter examples on sourceforge contain the new path to squeezeboxserver, to be consistent with the new name.
