The value of bitcoins
I think the idea behind crypto currencies and blockchain technology is great, and I’m a big fan. Remove the need for central banks and intermediaries, and move power from governments to the people.

FreeBSD 10.0 & Hyper-V 2012 R2
FreeBSD 10.0 Production Release som ble releaset 14 Januar, gjør det mulig å kjøre FreeBSD som en virtuell server under Hyper-V 2012 R2. Det betyr at jeg kan kvitte meg med noen av de fysiske boksene vi har på datasenteret, noe som var på tide.
