Route your mic to speakers – Ubuntu PulseAudio

When testing my microphone on my laptop for use with skype and google hangouts, I need a way to route the output to the speakers. Eventually I found this bug on launchpad: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/483812 To sum it up: pactl load-module module-loopback latency_msec=10 (default is 200) this command will give you a number as output, for example 27. to stop the loopback execute: pactl unload-module 27 (replace 27 with the output of the previous command) Read more

Convert Percona Xtrabackup to mysqldump

Recently I needed to restore a MMM (MySQL MultiMaster) cluster after both databases become corrupted for various reasons. Evaluating the environment it was decided that we should use the current active node as a true state and use this as a replication point, and provide database backups so that transactions could be played back manually if required. We use Pecona Xtrabackup for a large number of clients and this was the case this time as well. I performed the backup completed the manual replication and got the nodes back in sync again.

The value ‘stable’ is invalid for APT::Default-Release

Over the Christmas break, as I pretty much do every Christmas holiday period, I upgrade my MythTV set-up. I pretty much stick to Debian for the OS and pull the MythTV packages from Debian Multimedia. Once upon a time I used to build MythTV from source and make my own packages, but I am getting lazy and time is becoming precious for me in other ways. So this time I decided to upgrade Debian testing (Wheezy) as it seems to be pretty stable and nearing completion, so that I could install 0.26 packages. Read more

IPTV, IGMP and rp_filter

Having solved a very interesting multicast issue at work recently I decided it was once again time to have a go at getting IPTV working from my ISP TPG. I used to run Bering leaf, but never found a package or could be bothered building igmpproxy (which seemed to be the way to go) for leaf, and so have never really sat down and looked into getting IPTV working properly.
