Why isn't Microsoft trying out Haskell? Reading "Coders at Work" I was surprised to learn that research/development of Haskell's GHC is financed almost entirely by Microsoft, yet they aren't using it even for internal purposes as far as I know. And for their own functional language (F#) they picked ML to build on.

I wonder why.

[phren0logy → old-gregg]

I don't remember where I saw this, but I recall reading that they actually considered it. Ultimately, however, the pure functional style just didn't jive with .Net very well, so F# was born to allow functional style to live along side of the rest of .Net comfortably. The F# lite syntax also takes some cues from Haskell.

WIP, but frontpage on ycombinator. Good work!

I like how the first sentence in the post is, "Please don't post this [to] proggit; it's still WIP." I guess HN is not proggit ;)

This is what I call up-to-the-minute hacker news. :)

Wow. This looks great. Maybe I'll finally get around to trying Haskell!

I tried it out.[1] You won't learn much, at this stage. It is a promising idea, though.

I've been going through "Yet Another Haskell Tutorial" for the past few days: http://www.cs.utah.edu/~hal/docs/daume02yaht.pdf

I've been having fun with it. I skipped to the exercises on page 20, and started reading and doing the exercises from there.

I downloaded a full platform install from: http://hackage.haskell.org/platform/

Nothing happens when I hit return after 5 + 7. I tried Safari and Firefox :/

Hi there. This happened last night after I was tweaking the number of FastCGI processes. I changed it from four backends to one. Then Lighttpd believed the backend was overloaded:

2010-03-01 07:16:21: (mod_fastcgi.c.2926) backend is overloaded; we'll disable it for 2 seconds and send the request to another backend instead: reconnects: 0 load: 131 2010-03-01 07:16:24: (mod_fastcgi.c.3569) all handlers for /haskell-json.fcgi on haskell-json.fcgi are down.

I doubt there were 131 requests to the FastCGI process at the same time but I'll have to seek more information about it. http://redmine.lighttpd.net/issues/1825

For now I've set it back to four backends as that never had this problem.

Great, working again.
