Dan Sugalski tells about the State of Parrot. It's really cool; he tells about how flexible it is; the languages it already supports. Parrot already supports quite a few different platforms.
I knew that; but Parrot seems like it's in pretty good shape. Dan is a really entertaining speaker.
Parrot can count from 0 to 100M in ~5 seconds; other languages (Ruby (+200), Perl (~160), Python (~120)) takes more than 100 seconds. :-)
