On: Joel Reymont's frustration with Erlang

[quasomojo]

joel rules. he will give any useful tech a chance. he approaches problems like an everyman. he isn't afraid to ask for help. i've watched him churn through lisp, haskell and ocaml, and now erlang.

i think he should give haskell another chance. it clobbers erlang on every performance metric, including massive concurrency, which we can now say erlang no longer "owns". otherwise i think c++ is the only option

[gregwebs → quasomojo]

Haskell is by far faster on a single core but does not scale as well across multiple cores (due to garbage collection differences).

[vegai → gregwebs]

It will soon, though. See http://hackage.haskell.org/trac/ghc/wiki/Status/Releases and "Parallel garbage collection".

A release candidate of ghc 6.10 should be out in a few weeks.

None of this would help Joel, I suppose, since he decided to move away from Haskell to Erlang for other reasons.

[gregwebs → vegai]

The new gc will be an improvement but is is till not as good as Erlang's garbage collection, which is per process.
