Woo hoo! A geek hat trick today.

• finish a Debian package (spamilter, hooks spamassassin in sitewide for all mail traversing a sendmail site)
• pulled a slashdot discussion out of the weeds with timely corrective information
• researched and supplied the correct origin for an entry in the Jargon files (Hanlon's Razor: never attribute to malice that which can adequately be explained by stupidity. See http://www.statusq.org/2001/11/26.html for the probably origin.

Now if I could just find a cheap 3 channel RC toy to raid for its electronics... (The green buggy from radio shack is a bust. Apparently three function remote means you can press it, stop pressing it, then press it again. Jerks...

Fixed and closed all my Debian bugs except for one wishlist item. Just needed a postive universal karma adjustment for what I have to do on the 26th. Fiduciary duty can suck.

Come to think of it, I better implement that wishlist item too. :-)

Well blow me down! The chip vendor gave me access to the developer docs. Sadly they do not cover the part of the chip I need. I need to get access to the SDKs, but I'm making progress.

The DMA video frame copier is showing great promise. It correctly copies all the words without the 75% droppage that cacheline flushes cause. I'm still doing something stupid in the DMA descriptor link fields. I can't get them to work so I would have to repeatedly reissue the DMA requests. I'd much rather just make a DMA descriptor chain that is a loop so it runs forever.

Initial calculations show that 30fps update should take about half of the PCI bandwidth. If all the other devices are running at full speed that can account for another 25% so it shouldn't have a negative performance impact. We'll see.
