What I read last week 5.1

[1] Better than Free
Free is the new black

[2] A computer scientist who doesn't include 'give up' in his lexicon
Wow

[3] Google App Engine for Developers
If only they had a Grails version

[4] The technology that will save humanity
I wish I had a lazy bar or two to build a solar thermal power station on the farm

[5] Coal saver
Is it coal that it's saving? Or something bigger?
