Booting EC2 instances with RAID0 ephemeral drives

This is the little bootstrap script I use to create a large XFS filesystem backed by ephemeral drives assembled in RAID 0 for speed.

A month into the HTC One X

Like:

4G LTE network when available, feels faster than wifi
industrial design
GMail and Google Voice support
Google Maps
Phone speed

Dislike:

battery is enough for 8-12 hours, that’s it.
Software updates are very flaky and need to be retried numerous times.
lack of accessories (like a nice case)

Coming from an iPhone 4, the transition is a bit rough, particularly in terms of usability. To me, the sheer network improvement was worth it.

First day of HTC One X on AT&T in New York

So far so good. The screen is gorgeous, better than the iPhone’s. The new 4G LTE is really fast; a welcome change from the slow 3G AT&T network. The software is decent. Productivity apps tend to be better if you use Google Apps for Business but the glue that holds apps together is definitely weaker than iOS.

Still, this phone is fast.

Precise Pangolin

I’m giving Ubuntu 12.04 a quick spin this morning. Intrigued by the head-up display.
