August 27, 2012 Matplotlib, biopython segfaults in OpenSuSE 11.3
At $WORK, a user discovered a fun feature of OpenSuSE: that you can segfault Python quite easily. Watch:
```
$ python
>>> import matplotlib.pyplot
Segmentation fault
$ python
>>> import Bio.PDB
Segmentation fault
```
The reason, at least for us, is that we'd installed the python-matplotlib package from the OpenSuSE Education repository, and python-numpy from the standard OpenSuSE library. The problem was fixed by running:
```
sudo zypper install python-numpy-1.6.2-39.1.x86_6
```
which forced the upgrade from 1.3 to 1.6.

But, whee! you can actually install 1.6.2-39.1 from TWO repos: Education and Science. Yes, my fault; my OpenSuSE installs are all over the fucking map. But I wonder what it might take to ensure that minimum versions are somehow noted in RPMs, or, you know, not having multiple universes of packages. Fuck, I hate OpenSuSE.
December 14, 2009 chkconfig woes
Irritating: chkconfig on RHEL/CentOS returns non-zero if a service isn't configured for a runlevel. IOW, you can do:
```
chkconfig --level 3 foo
```
and have 0 returned if it's on, 1 if it's not.

But not SuSE; nope, it just returns 0 whether or not it's enabled, or even if the service itself doesn't exist. Because, you know, grep doesn't get used enough.

I'm doing this because I'm trying to use cfengine 2 to manage services. This works well in CentOS, where you can add something like:
```
service_foo_on = (ReturnsZero("/sbin/chkconfig --level 3 foo"))
```
and it'll work. ("servicefooon" is a bit of a misnomer, because I'm checking runlevels, not whether it's actually running.)

Update: Nope, I'm wrong. chkconfig --check does exactly what I want. Many thanks to yaloki on #openSUSE-server for the help.
