July the first 2013 marks the discontinuation of Google Reader, which is sad.

Of course this is always the danger of using propriety code either as a local application or as a web service.

I have migrated to Tiny Tiny RSS which is an active open source project.

Today I finally took took the plunge and update to org mode version 8. As it had be announced as a major change and introducing breaks I thought I would give it a while.

So via elpa I am now running 8.0.3.

The big thing for me that broke was org2blog which I use to write content for both my personal site and theaudiopodcast site.

After a little exploring I find a working version though.

How I did it,

First you should backup the old org2blog install.

Then

cd .emacs.d

git clone https://github.com/ptrv/org2blog.git

git checkout org-8-support

then restart emacs.

Today while setting up a raspberry pi to be used as an airplay audio server I came across an error message which started,

unknown pcm cards.pcm.front

As I knew that the audio output was working fine normally I suspected a permissions issue.

In creating a new user under RPI Debian Wheezy, which I tend to do all the time for security reasons, the users is not add to the audio group, which is required.

So this command adds the user bob to the group audio,

sudo usermod -a -G audio bob

So if you have an audio problem that is fixed by running the application as sudo then checking the user is withing the audio group is a good starting place.

You can check what groups a user is in by just typing,

groups

Found this online [here][1] as a dirty way of getting synergy to boot on a debian rpi image at auto login.

/usr/bin/killall synergyc while [ $(pgrep -x synergyc) ]; do sleep 0.1; done /usr/bin/synergyc </blockquote> [1]: http://nixnote.blogspot.co.uk/2012/02/autostart-synergy-on-debian.html

After an overnight, with little sleep, in Stansted Airport I finally made it to the Live Code Festival in Karlsruhe. Enjoyed a stroll around the city and visit to the local museum, free on Happy Friday while enjoying the sunshine.

In the evening attend the two concerts of livecoding which displayed a typical mix of technical instrest and compositional concern though I suspect that my tiredness did not help.

Was great to get an opportunity to hear BenoƮt and the Mandelbrots and I enjoyed the beginning of the Cybernetic Orchestra set.
