I recently upgraded two of my computers to Ubuntu 8.10 (Intrepid) which was in alpha at that time and is beta at present. Some small thing always seems to break for me with an upgrade and this time there were two issues, which I have finally managed to sort out this week.
1. Google calendar in Thunderbird
I had my google calendar nicely set up in Thunderbird using the Lightning and Provider for Google calendar extensions. After the upgrade, my google calendar wasn't displaying anymore and moreover all the calendar related menu items were disabled. Finally I found the answer here.
I uninstalled lightning and provider, did a 'sudo aptitude install libstdc++5', then reinstalled the extensions. On restarting thunderbird, the calendar was now there as before.. a relief.
2. Fingerprint reader and thinkfinger
After the upgrade, my fingerprint reader appeared to not be working. Swiping the finger elicited no response at all. Searching in launchpad brought me here showing others were having the same issue. Surprisingly it seemed that the fingerprint identification was working, but needed a carriage return (Enter key) after the swipe to work. Some workarounds are beginning to appear (though nothing final) and what worked for me was a simple change in xorg.conf. Adding the line
'InputDevice "Generic Keyboard"' to the "ServerLayout" section got the reader working again after a restart of xserver.
Hope these help someone with simlar issues.

Eepee - the electrophysiologist's tool
04 Oct 2008
Eepee is my attempt to make a tool for cardiologists to analyze ECG and Electrophysiology tracings.
The study of these tracings requires one to make various measurements and compare them. While this is available along with the acquisition software in the lab, review of these tracings for teaching or learning is usually done with printed / scanned tracings without an easy way to dynamically measure things. The usual approach is to use project a series of these tracings on powerpoint, while any measurements have to be made on a paper copy with hand-held calipers.
Eepee is an attempt to smoothly provide all this functionality with digital images. At its current state (version 0.9), the user can load any digital image, calibrate the x-axis with known measurement in the image and then use digital calipers to make measurements. Notes can also be made for any image. Notes and calibration are automatically stored for each image and are reloaded the next time.
It is still not past version 1.0 meaning that it is beta, but it is getting relatively complete and stable. It works on windows and linux and can be got here. I welcome any suggestions / comments.
