25th of April

Its ANZAC day here in Australia.

Farm news
Crunching of CPDN work continues. I keep getting stuck uploads that I have to use the dial-up to get them unstuck. It gets a bit time consuming but better than wasting 110 hours of computing.

RPi upgrade
I did another attempt at upgrading one of the Raspberry Pi's from Debian Wheezy to Debian Jessie (the testing release). This time seems to have been a success and its got BOINC 7.2.42 running on it from the repository.

The process I used was:
1. Edit /etc/apt/sources.list and change it to read:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
2. Do a sudo apt-get update command
3. Get a cup of tea while it updates the list of packages
4. Do a sudo apt-get dist-upgrade command
5. Make a pot of tea and drink it
6. Do a sudo apt-get autoremove command
7. Do a sudo apt-get autoclean command

The dist-upgrade took me around an hour with a few questions as it goes along. The last time I tried this I got stuck on one of the questions, this time I took the defaults. You don't actually have to do steps 6 and 7, its simply to free up space by getting rid of the old packages.

I took a snapshot of the SD card before doing the upgrade so if it goes horribly wrong at least you can reimage the SD card. Also if your Pi is running BOINC work its best to finish it off and report it before starting.
