Weekend in Philadelphia

Spending the weekend in Philly with Victoria. She had to go to the clinic to do some paperwork, so I'm here at the coffeehouse trying to get some stuff done.

Unfortunately, I'm not sure if somebody else is running BitTorrent, but today for some reason the coffee house's Internet access is ridiculously slow. I have to wait ten or fifteen seconds for web pages to appear, which pretty much rules out doing connecting into the office over ssh and getting some work done.

As a background task over the last few days I have using BoundsChecker to profile some upload zip code I have in my product. Achieved a 133% performance improvement in large zip uploads with few files (400 MB zip archives containing 70 or 80 files), and a 64% improvement in small zip uploads with lots of files (4 MB zip archives containing 2500 files).

Performance profiling is one of the more fun things I get to do at work. Hand optimized assembly code is your friend.

I lost one of the rubber nubs from the Bose headphones I got from Uncle Richie and Aunt Aggie two Christmases ago. The nubs were pretty worn out (they get alot of use) and I was thinking about buying a new pair anyway. I dropped the tiny piece of grey rubber onto a concrete walkway last night and spent several minutes trying to find it before giving up. It's just annoying because I would have continued to use the old ones until I bought a replacement, and now I can't use my iPod until I find somewhere to pickup a new pair.

Ok, enough rambling for now...
