Dear list,
I'm trying to create unboxed REPA array from unboxed Vector, but I keep getting
this type error:
ghci :m + Data.Array.Repa
ghci :m + Data.Array.Repa.Repr.Unboxed
ghci :m + Data.Vector.Unboxed
ghci fromUnboxed Z (Data.Vector.Unboxed.singleton 1)

Thanks!
This makes it look like you've got two versions of vector installed,
This is true, I have vector-0.9.1 and vector-0.10, but
with Repa built against the version that _isn't_ 0.9.1.
this, I think, is not exactly correct:

No, no, Repa is build against
so if it's waiting for a Vector from vector-0.9.1 it means Repa is
built against this version (which is not the latest on your computer
thus the problem).
Yes, as I said the latest one is 0.10. Is there any way to sensibly manage this
kind of

Most existing Haskell books and similar teaching material is aimed at
programmers who are new to Haskell. This survey is to assess the community
interest in teaching material covering advanced topics beyond the commonly
taught introductory material.
Something to consider is that it's not so much whether the material is
basic, advanced, or intermediate; it's that the way it's being presented is
boring and ineffective.
Take the Head First Java book, which was deliberately engineered to
overcome precisely this hitherto neglected aspect of

Hi,
going deeper i found the following:

HaskellDB is converting from SqlTimestampT (no timezone defined) to
CalendarTimeT (timezone required). This conversion tries then to be

I am glad to announce the first public release of test-framework-golden — a
golden testing library.
Hackage: http://hackage.haskell.org/package/test-framework-golden
GitHub: https://github.com/feuerbach/test-framework-golden
Golden tests are similar to unit tests (as implemented in HUnit), but
Apparently using STUarrays in an imperative fashion is fraught with
peril (and the performance of molasses).

Hello!
Perhaps package imports would do the trick?

Not exactly something you'd want to release in a module in a hackage
package, though.

It doesn't. The sandbox feature requires a little UI work still.

I'm a big fan of TDD and tend to approach all languages by learning
how to TDD in them.
As such, you mention that this is similar, could you please send some
links about this?
Cheers!
