Werner Vogels, CTO at Amazon.com, posted a paper on Amazon’s internal called “Dynamo” about two year ago that was selected to be presented at the 21st ACM Symposium on Operating Systems Principles. Dynamo is Amazon’s internal cluster software platform. It is really their operating system since they add “hot swappable” commodity hardware to the system in plug-and-play fashion as needed.

I know I’m late to finding this particular paper since it was first published about two years ago. Better late than never!

HTC HD2 is not the best, but tethering rocks

General |  None of the above · 09/05/2010

I’ve got a laundry list of issues with my HTC HD2 (Twitter OAuth fix is a no-show so far, Windows Phone random reboots, no Windows Phone 7 planned, slowest music player ever — that’s just getting started) but the one bright spot is the ability to tether over a USB connection to T-Mobile’s 3G network. I just ran a speed test and here are the results: 3.82 MB/s download and 0.63 MB/s upstream. Sure beats 56K!
