Re: [Haskell-cafe] Hackage checking maintainership of packages

I would even be happy with newhackage sending every package maintainer a quarterly question Would you still call your project X 'maintained'? for each package they maintain; Hackage could really give us better indications concerning this. This sounds to me like a very good idea. It could be as simple as If you consider yourself to be the maintainer of package X please just hit reply and send. If Hackage doesn't get an answer, it'd just would display some red text like This package seems to be unmaintained since D.M.Y. Best regards, Petr For those packages that give a repository, a query could be done automatically to see when it was last updated. It's not the same thing as 'being maintained', but is less annoying for those people with many packages on hackage.

[Haskell-cafe] floating-point comparison (was haskell gsoc proposal for richer numerical type classes and supporting algorithms)
--- On Thu, 4/8/10, Gregory Crosswhite gcr...@phys.washington.edu wrote: From: Gregory Crosswhite gcr...@phys.washington.edu On a tangental note, I've considered coding up a package with an AlmostEq typeclass that allows one to test for approximate equality. The problem is that different situations call for different tolerances so there is no standard approximate equal operator that would work for everyone, but there might be a tolerance that is good enough for most situations where it would be needed (such as using QuickCheck to test that two different floating-point functions that are supposed to return the same answer actually do so) to make it worthwhile to have a standard package for this around for the sake of convenience. Anyone have any thoughts on this?
