I have recently started playing with Amazon SimpleDB, part of the Amazon cloud computing offering, which is basically equivalent to Google Bigtable. Being a ruby enthusiast, I decided to use the right_aws gem from RightScale. The only problem, is that right_aws still does not support batch attribute insertion, which severely limit performances. Since I’m planning to use Amazon SDB for BayesFor, where we need performance, I implemented it. You can find the code in sdb_batchput.rb

I have been using a ChromeOs cr-48 device for a few weeks now, and these are my findings. I tried using the cr-48 for as many tasks as I could, including writing, image editing and even coding. Am I satisfied with the device? For some tasks, it’s just awesome. For other things, the entire cloud model is still not just there, either because of completely broken workflows, or small details.
