He's at Google and recently announced their new static analysis framework for Python: http://news.ycombinator.com/item?id=1054036

Sure... but I wish I could still read him sometimes. There is no blogger I enjoy to read these days (mostly they are too techinical...)

I heard he's stuck in a fish tank, swimming along the edges of the glass to find a way out.

Could someone please explain this (joke?) to me?

It's a reference to this blog post: http://steve-yegge.blogspot.com/2008/10/programmers-view-of-...

It's something he used to notice his goldfish doing before it died of loneliness, apparently.

It's a sad story and very well written.
