Caja: Capability Javascript
Ben Laurie: I’ve been running a team at Google for a while now, implementing capabilities in Javascript. Fans of this blog will remember that long ago I did a thing called CaPerl. The idea in CaPerl was to compile a slightly modified version of Perl into Perl, enforcing capability security in the process.
Hopefully like the work of Douglas Crockford [via Patrick Logan], the parser itself is (or will be) written in Simplified JavaScript.
This could be a useful, as an option, for CouchDB. I don’t yet see the value for allowing even a sanitized subset of scripts through the UFP to Venus.
