They have poor performance, memory retention issues, and an overall poor design. When Lift relied on Scala's Actors, a Lift-comet site needed to be restarted every few weeks because of pent-up memory issues.

Scala's Actors are not expanded by Akka (although Akka Actors may replace the existing Actor implementation in the Scala library). Akka is yet another replacement for Scala's Actor library and Akka's distributed capabilities are weak and brittle. Also, Lift's Actor library and Martin Odersky's flames about it paved the way for Akka because I took the heat that might have driven Jonas out of the Scala community when Akka was a small project. > To me it'd be the other way around: you'd have to develop Actors in > Haskell, don't you? > I've come to understand that Actors are a weak concurrency/distribution paradigm. Anything that has a type signature Any => Unit is not composable and will lead to the same kinds of issues that we're looking for the compiler in Haskell to help us with (put another way, if you like Smalltalk and Ruby, then Actors seem pretty cool.) On the other hand, many of Haskell's libraries (STM, Iteratees, etc.) have a much more composable set of concurrency primitives. > Or maybe you don't mean the same thing by 'Actor'? > > > 2011/12/19 David Pollak <[email protected]> > >> On Mon, Dec 19, 2011 at 2:04 AM, Ivan Perez <[email protected] >> > wrote: >> >>> I'm actually trying to make a list of companies and people using Haskell >>> for for-profit real world software development. >>> >>> I'd like to know the names of those startups, if possible. >>> >> >> I am building http://visi.pro on Haskell.
