OK, it's cold, and dark, and will start raining overnight, so here's an off-topic query:

Any recommendations here inside the firewall for buying quality, authentic computer parts, online or off? I want to boost the RAM in my Macbook Pro to 8gb from 4. Alas, that means chucking the two 2gb chips in there now and replacing with 4gb pieces.

Here's the spec:
204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM

Taobao (love it or hate it) has not helped me out here, but I did stumble on the local version of newegg.com, a big mail-order house in Los Angeles. Here's what I found on their site:

4gb 1066 MHz DDR3 SODIMM chips

at 299 rmb each for the Chinese-made Kingshare and 369 rmb each for the Korean-made Samsung, these are comparable to US mail order prices of $90-100 (and a lot cheaper than the $400+ that Apple charges).

Any other quality suppliers in China?
Any warnings or cautions about brand or compatibility?

best thanks!
