Lots of pages out there address problems people have getting sound to work with VMware running on Linux hosting Windows but none of those solutions did it for me. VMware Workstation 6 insists on using /dev/dsp which for some strange reason I didn't have. I noticed I had /dev/dsp1 through /dev/dsp5 but no plain /dev/dsp. A few minutes fooling with Audacity showed me where each of those played, and /dev/dsp3 seems to play through the speakers on my Audigy 2 so I knew that was the one I wanted it to use. I simply did:
sudo ln -s /dev/dsp3 /dev/dsp
and that seemed to do the trick.

Wireless actually works except for the campus network. I can connect to the network over at the Inn (by accident I assure you) but our campus network uses WEP and does not broadcast SSID. Something about that kills it. Lots of Googling hasn't produced an answer. Michael suggests trying ndiswrapper.

I was surprised and pleased to see that CVtypes, our python ctypes wrapper for OpenCV, actually worked with my Logitech QuickCam Pro 4000 right out of the box. Later when I started to seriously try it out I was disturbed to see I was only getting 10 frames per second. I tried setting the frame rate with the interface provided by highgui but that fails for the frame rate. Anyone know why? Then I discovered
setpwc
a command-line utility for viewing and setting parameters on cameras that use Phillips chips. It revealed my camera was
set
for 10 fps. It was easy to change the setting to 30Hz at 320x240 and now my OpenCV apps run at 30Hz. I was never able to go above 15Hz on Windows XP. This is great.

In both Python and VMware I've noticed that attempts to open a link in the browser failed with a very strange
file:// link
containing double quote characters. A bit of searching revealed this is a problem with the calling syntax from Firefox in System -> Preferences -> Preferred Applications. Changing from "Custom" to "Firefox" so the Command is
firefox %s
fixes things nicely.

Murray kindly pointed out that my ssh port was getting assaulted by various lower forms of life trying to guess a user name and password. Yikes! A bit of Googling revealed firestarter a nice GUI for iptables. A few rules limiting access appear to have shutdown the script kiddies.

I need to test our applications on several versions of Windows and the Flash development environment only runs there. My machines still dual-boot but that is a bother. So I decided to check out ways to run windows on Ubuntu. I first tried QEMU with the kernel accelerator. There are lots of fiddly command-line flags to get right but it worked pretty well. I successfully installed Windows XP though it took a long time. I discovered some tips about disabling ACPI and that sped things up quite a bit. Now full of confidence, I decided to install Flash CS3. The install took a while but it does when running native as well. Unfortunately, when I tried to run the Flash IDE, QEMU would crash hard with bus error, core dumped. I've posted a query on the QEMU forum but haven't gotten a reply yet.

I wanted to make /home its own partition to ease backups, synchronization, and future upgrades. This is how I did it. I'm no expert so beware of taking these as instructions. I got most of this from this post .

When I type
ssh gb-cs
I mean
ssh gb-cs.cs.unc.edu
but I couldn't get that to work consistently at home. I'd add it to the Search Domains section of the DNS tab in the Network Settings dialog but next time I hibernated or rebooted, it would be gone.
This tip
suggested adding a package and then making a simple change:

Pete says check out
istanbul
when I need to make a screencast.
xvidcap
is another possibility but it doesn't seem to be in Synaptic Package Manager.
