I can’t believe it’s taken me this long to learn this: Python’s default argument values are only evaluated once during runtime. I’ve never encountered this before because I don’t use default arguments very often, and when I do, it’s often…
Install Visual Studio 2008 SP1 Express Edition. Go to the command prompt. First, I had to set the following variable:
|
1
|
C:>set VS90COMNTOOLS=C:Program FilesMicrosoft Visual Studio 9.0Common7Tools

I needed to return all the members of an object as an XML document in Python. I used the ElementTree library to do this. The class in question is pretty basic: It has a constructor, member variables, getters and setters…

I ran into a problem tonight with my Roku box where SquidGuard was seeing Roku’s NetFlix access as a security threat. So, to…
By default, Squid sends HTTP headers on every request that can give away information about your internal network. Here’s an example of these headers:

If you have a switch, access point or other piece of network hardware that supports 802.1q VLAN tagging, and you’d like to your FreeBSD system to recognize them, it’s a pretty straight-forward configuration. I’ll use examples from my network to…
Most of us don’t have native IPv6 Internet connections at home. Fortunately, it’s easy (and free) to get connected to the IPv6 Internet. Here’s how to get your FreeBSD box connected.
I spent some time thinking about backup strategy, and I decided for my purposes, I’d like to handle the staging process (getting all the files put together), and I’d like the backup solution itself to simply upload the files –…
