Previously it has not been possible to use the camera module on FreeBSD due to the RPi tools not working on 64-bit architectures. I have recently added a version of the u-boot port for the Raspberry Pi 3 that is built in 32-bit mode.

For the past few years I have been operating a small number of Arduino Ethernets with DHT22 sensors, push data into Graphite. They have worked reasonably well, but had one major issue. Graphite required that the data flow include the Unix Epoch time and the Arduino time counter over flows every ~50 days.

For awhile I have been using a Tarsnap backup script written by Tim Bishop. It is very handy but recently I was setting up Tarsnap again on a new machine and I noticed that it is not designed to be run more frequently than daily. So I decided to take a stab at making it handle being run more often and keeping the number of daily/weekly/monthly backups that are actually desired.

In the past we had to use the old SysV IPC sysctls and change the UID that each PostgreSQL server ran as under in each Jail. Which was annoying and error prone.

For some reason I could not find any pictures online of the awesome shirt from the EuroBSDCon 2013 DevSummit. So here it is!
