Inexpensive Performance

Taking a break from MemoryTraceGenerator.cpp to mention:

I'm replacing the motherboard and CPU in my dad's home desktop with an Athlon 64 x2 Kuma at 2.7 GHz and an $80 EVGA motherboard with a GeForce 8200 integrated video chipset. The total here is roughly $200 if you also purchase several GB of DDR2 RAM. This wouldn't be a terrible CUDA development platform, particularly if someone loaned you a higher-end GPU. Even without, its integrated GPU is still capable of accelerating typical applications such as video decoding.

I only mention this because what one might consider today's low-end desktop is astonishingly powerful.

It's also my first time touching AMD.

Winds

Design fail: high winds bristling down Peachtree St at the 130 ft level tend to pass over and around
the balcony railings of our condo creating quite a bit of commotion. I would estimate the power spectrum has peaks at the 10 kHz frequency as well as the 5 Hz and ~100 Hz frequencies. The noise was so loud and so stationary that, at Emma's suggestion, I slept wearing ear plugs from my shooting kit. That worked for roughly two hours.

Can't we just remove the railings from the balcony during high winds?

Webcam

Emma's webcam is now operational. I am using webcamXP 5 [free!] to make HTTP POST calls to upload images. At present, the server will store only the most recent image, so don't expect a log. It is updated once every hour. I may enable serving the most recent 24 hours, but that functionality will not come online today.

I used a PHP script on the server to receive the files and authenticate the poster. If you guessed the passphrase and spoofed our IP address, I guess you could upload an image of a giant eyeball and it would appear on our webcam page.

Here it is. Bookmark this:

Note the billboard between the Viewpoint and the T-Mobile sales office. The nude male ad has been replaced for an ad for The Mighty Boosh on Adult Swim.

GPU VSIPL Press

GPU VSIPL is now featured on NVIDIA's CUDA Zone: GPU VSIPL. NVIDIA lists it as an application, although we only wrote the application to demonstrate the library (and achieved a 75x speedup over the world-famous TASP VSIPL distribution).

In unrelated news, Emma and I have completed our move. I need to set up her webcam.
