Compiled Common Lisp with SBCL, which is easily the fastest free implementation, is still significantly slower even if you litter the Common Lisp with type hints and declaims. However, they are both fast enough for most applications, and SBCL is significantly faster than any of the mainline implementations of other popular dynamic languages.

No implementation of Smalltalk, Lisp, Ruby or Python even comes remotely close to the JVM or the CLR. Out of all of the languages he listed, only Erlang has an implementation that is even in the same league. Are you retards honestly going to compare the JVM or the CLR to SBCL, Ruby MRI or CPython? CPython uses a reference counting garbage collector and isn't even thread safe. Ruby uses a notoriously bad naive mark and sweep garbage collector. Comparing these to the JVM or the CLR is just fucking retarded.

Between Gnome 3, KDE 4 and Unity this talk of desktop Linux should be completely dead. Exactly how much do they need to fuck up to make you realize it's over? Is Xfce - the complete reimplementation of the Windows 95 UI - your last hope or are we going to try to convince the masses to learn Haskell and configure Xmonad after that? Just how low do we need to go here?
