Adding FGL to the hierarchical libraries
by Martin Erwig 16 Jan '04

16 Jan '04

Hi there, Abe Egnor and Isaac Jones at Aetion Technologies have refactored the modules of the FGL (http://eecs.oregonstate.edu/~erwig/fgl/haskell/) into the new hierarchical name space. It is therefore possible now to add the FGL directly to the hierarchical library structure. I don't really know how that works, but I would like to contribute the FGL to the hierarchical libraries. (I haven't released the new version yet, but plan to do so soon.) I have attached the modules to this email. If you want to add them, please go ahead. If you have any questions, please let me know. Thanks, Martin

So, I guess we will be stuck with concrete > data structures for a while :-) I second Daan's opinion here. The Haskell community has been searching for good generic collection interfaces for a while and hasn't come up with anything that is obviously the right thing. In the meantime we're stuck with poor data structure support because everyone is waiting for the wonderful generic collection library to come along. Having a well-designed and consistent concrete data structure library is certainly a lot better than nothing. Indeed, it would be more useful in a sense because the barrier to adoption would be low, and it wouldn't have an impact on the existing libraries. If such a thing were to materialise, I'm sure we'd import it into the hierarchical libraries that are shipped with GHC, Hugs & nhc98. Perhaps DData is pretty close to what we're after. Would the interested parties care to thrash out the details and present it to the wider community for comments? Cheers, Simon

Hello outbound, At last you have an opportunity to purchase good directly from manufactures. You save your money purchasing quality products from our plant's store. Today we present you FatBlast product. What is FatBlast actually? Fatblast is an advanced fat-binding supplement that removes fat from the foods you eat! Formulated with the powerful fat-binding fiber Chitosan, the proprietary blend of all-natural compounds...

The Data.Tree module in base is certainly quite small. You've made two changes: * made the types abstract, but provided the equivalent constructor and destructor functions. I'm not sure that gains anything. * added upwards and downwards accumulators (except that your "upwards" accumulator is actually a variant downwards accumulator, with quadratic performance). It might be worthwhile to add fold and accumulators. I was also thinking of adding unfolds (pure, and monadic depth-first and breadth-first).

ANNOUNCE: Cryptographic Library for Haskell
by Dominic Steinitz 12 Jan '04

12 Jan '04

I would like to annouce a new release of the Haskell Cryptographic Library (1.0.1). See http://www.haskell.org/crypto/ReadMe.html for more details. This library collects together existing Haskell cryptographic functions and augments them so that they: · Have common type signatures. · Can be used with the standard mode and padding algorithms (in the case of block mode ciphers). This release includes much improved support for public / private key pairs and contains: · DES · Blowfish · Cipher Block Chaining (CBC) mode · PKCS5 and nulls padding · SHA-1 · RSA · OAEP · ASN.1 · PKCS#8 Dominic Steinitz

Oops, instead of "will be removed in 6.4" I should have said "was removed in 6.2" of course.
