One of the Huon kids over at Bob's Drone Blog has a really cool Scientific Investigation Awards project - an Accelerometer data logger, or "Accelerologger" (I like the name too!). He's stuck with a small coding bug and has asked for help. I think I see the problem. Wisely, Bob's disabled comments without a login (see my Computing Rule 5), so I'm adding notes here on my own blog.

Well, here's a first for me: go to local Dick Smith's, buy a cheap printer, for my wife (HP Deskjet 3940, AU$66). Because I don't really care about printing from Linux, I didn't care if it works or not on that OS, just bought whatever Windows printer was cheapest.
Brought it home, plugged it into my PC (in Windows) and it works, after installing drivers and software and about 15 mins of setup time.
For the heck of it, I rebooted to Linux to see what would happen. Well lordy “New hardware detected: HPdeskjet3940” and an offer to set it up. After 5 minutes — just accepting all the standard options — out comes a test page, in colour, bi-directional and fast.
Neat. Linux is ready for me....

I think I may have figured out the issue with my CD recorder. It seems to fail more when the weather is hot (as in, more than 32° C ambient). The internal case temperature would be in the low to mid 40s then, and this is probably close to the maximum operating temperature for the device (a SONY CD-RW CRX140E).
So, either I confine my CD writing to early in the morings on hot nights, or I evaluate some sort of cooling solution.

Place these settings in your
The RADEON driver (
radeon) supports the following options for the RV280 chip (which is
found on RADEON 9200 boards). The default values are in red:
Option "AGPMode" "1"(driver currently supports up to x4)
Option "AGPFastWrite" "off"(only used when DRI is enabled)
Option "BusType" "AGP"(if driver's bus type detection is wrong)
Option "DisplayPriority" "AUTO"(set to
"HIGH"to fix tearing)
Option "EnablePageFlip" "off"(turn
"on"3D page flipping for better performance)

may help KDE. Don't use
BusType unless the log shows the driver
has selected a PCI bus for the card...
Note:- when playing with Xorg 6.5 I got X crashes
EnablePageFlip turned on.
