Haskell Weekly News: April 03, 2006
Greetings, and thanks for reading issue 31 of HWN, a weekly newsletter
covering developments in the Haskell community. Each Monday, new
editions are posted to the Haskell mailing list and to The
Haskell Sequence. RSS is also available. Headlines also go to
This section covers activity on Haskell' standardisation process.
* FFI, 'safe' and 'unsafe', parts 1 and 2
* newtype deriving
* Standardise deepSeq
* MVar semantics
* Thread priorities
* Concurrency, parts 1, 2 and 3.
* FD improvement, variable quantification & generalised
* Mobile Haskell. Dmitri O.Kondratiev asked about running
Haskell on a PowerPC Windows Mobile device. John Meacham
responded with some interesting notes regarding Haskell on the
* GHCi as a debugger. Lemmih wrote on "whether it would be
possible to call GHCi from interpreted byte-code. It turned out
that it was, and it was even fairly easy". Great stuff!
* Clearer reflection. Krasimir Angelov proposed some ideas for a
better Reflection API for Haskell. Currently we have Typeable and
Data classes which provide some pieces of information about the
data types at runtime. typeOf provides runtime information about
the type of a given variable. dataTypeOf provides almost the same
information but with some extras. There is some overlap between
the TypeRep and DataType types. Some pieces of information you can
get from the TypeRep, other from the DataType and some other from
both of them. There is also an information which is inaccessible
from either TypeRep and DataType.
Quotes of the Week
Seen on #haskell:
Lemmih:: calling an out-of-scope function isn't as easy as I had hoped
TuringTest:: They got it work in Haskell without understanding Haskell.
It is quite an achievement, of some description.
tennin:: [very #haskell] anyone know of any good books/papers on the
application of category theory to databases?
Smokey`:: I can't believe it, Haskell is starting to draw me away from
C++... I swore i'd never turn from C++
