This is the plan I think, or something like it. Currently package are referred to by unique hash that sort of works this way, but there are few unfortunate restrictions in GHC and cabal that need to be lifted to allow future installations

I think for modules to help here, the interface would have to not change between versions, useful for ByteString, not so much for Yesod. As it stands now, cabal's constraint solver will prevent the installation of a package that indire

Sandboxing is merely a stop-gap to reproducible builds (I hope). Nix style multiple instances of the same version of an installed package will lead to better reuse, thus faster builds. If the fingerprints can be made precise enough, binary

The package management story in Haskell, I don't want to say broken, is just too complicated for beginners, err actually everyone. For instance, to install stylish-haskell you will ultimately need the "happy" executable, but

Pretty good points, I have few comments. > It's not easy to interpret these numbers and you have to have quite a deep understanding of statistics, i.e you can be in the normal range and be sick, and you can be outside and be healthy

Yeah its a bullshit line. There are certain class of functions in Haskell that can be completely derived from their signature (see djinn) but Haskell's type is not strong enough for automatic formal verification. I would prefer is peop

We manage all deps in our cabal file, and have scripts to make sure that what is in package database matches the cabal file (this way we can upgrade versions without manually unregistering and reinstalling). Like you said, there is nothing

Haskeller at IMVU. I was surprised how fast people were picking up the language when I started It is way different learning the language surrounded by teachers and a working environment. That was my takeaway.

The library in question was using unsafePerformIO to open a file handle. It was just a bug.

Haskeller at IMVU. Haskell could still benefit from a larger community. We have had to write some key low level tech, but we have been able to do so at an incredible pace. The /dev/urandom bug mentioned was caught by us because we

I'll expand on the details. We have a simple mechanism for controlling access to IO. There are a series of type classes that provide access to all of the IO based services (mysql, redis, memcache, etc.). All of the request handlers are
