I always love the "my programming language is smaller" and the "build a webserver in only 3 lines" type posts. This one is about smaller. He mentions Sector Lisp (a marvel at about 436 bytes, Tiny Lua in at 100K. Pretty cool. But as much as I admire Sector Lisp, it's the bare bones Lisp. I need to add scaffolding around it to do anything really practical. Likewise for Tiny Lua, it needs a ton of things before I can use it. Once I get done adding some support, it's up to 300K, the size of regular Lua.
(and on the other hand, Webserver in 3 lines, that's after pulling in 2MB of libraries, I guess that code doesn't count ;-) )
