OpenSolaris upgrade
Jun 11th
OpenSolaris 2009.06 was released this month. Upgrading my home file server was pretty easy.
# pkg refresh && pkg image-update
Everything worked smoothly until the last part. The new boot environment did not activate correctly. Some further digging revealed that one of the two disks in my rpool was set with and EFI disk label (I’m not sure how that happened). I found some good information online, and soon enough, I was up and running with the new version of OpenSolaris.
ZFS was upgraded in this new version, so I upgraded it on my file server.
# zfs update
And like that, I was done. I will be interested to see if the drivers (rge) for my original NIC are better. If so, I may be able to set up trunking on the two NICs to double my throughput. I did notice that CIFS seems to work a little better. That is, I didn’t have to coerce the machine to share via CIFS like I used to.
PyGTK Chart Widget
Jun 6th
pygtkChart is a chart widget for GTK that offers line graphs and pie charts. It’s simple to use, but it is lacking one feature that I really wanted: bar charts. I added a bar chart widget to the package, but I have not been able to get in touch with the original author to contribute the code back. So, here it is.
Download: Clone from git://github.com/notmyname/pygtkChart.git or view the source at http://github.com/notmyname/pygtkChart/tree
Installation: $ python setup.py build && sudo python setup.py install
Description: I have added two new classes: BarChart and MultiBarChart. BarChart provides a simple bar chart. MultiBarChart allows for grouped bars. The code is fairly well commented and should be easy to follow.

UPDATE: a new version has been released
