Booting Ubuntu-14.04 cloud images without a cloud

Ubuntu-trusty

So, Ubuntu-14.04, Trusty Tahr, is out; and booting the cloud images requires a bit more hacking than booting the 12.04 cloud images. Here goes:

Get the image, resize and loop-back mount it:

wget cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-disk1.img
qemu-img convert -c -O qcow2 trusty-server-cloudimg-amd64-disk1.img trusty-server-cloudimg-amd64-disk1_30GB.qcow2
qemu-img resize trusty-server-cloudimg-amd64-disk1_30GB.qcow2 30G

I was not able to find a script that does this, so I wrote one myself. I chose … Read the rest

Squeezebox and the new LastFM API

squeezebox_mr

Since my last post about SqueezeScrobbler on my Squeezebox, I’ve enjoyed 3 years of LastFM listening on Squeezeboxes, Linux and Mac boxes, iPhones and iPads.

Well, this fall, LastFM announced that they would hit my listening pleasure with dual strikes: deprecation of the old API and discontinuation of the radio service in other countries than the US, UK and Germany. … Read the rest

Christmas in Zurich

Merry Christmas and a happy new year from Zurich!

Vacation in a place you know this well is actually very relaxing. And good old Zurich is largely unchanged – even got chicken sweet and sour at the same place from the same guy as 12 years ago.
