  • Halfs, a Haskell filesystem. Isaac Jones announced the first release of Halfs, a filesystem written in Haskell. Halfs can be mounted and used like any other Linux filesystem, or used as a library. Halfs is a fork (and a port) of the filesystem developed by Galois Connections. In addition, Halfs comes with a virtual machine to make using it extremely easy. You don't need an extra partition or a thumb drive, or even Linux (Windows and Mac OS can emulate the virtual machine). See more at the Halfs site.

  • DrIFT-2.2.0. John Meacham released DrIFT-2.2.0, the type sensitive preprocessor for Haskell. It extracts type declarations and directives from modules. The directives cause rules to be fired on the parsed type declarations, generating new code which is then appended to the bottom of the input file. Read more here.

  • MissingH 0.14.2. John Goerzen announced version 0.14.2 of MissingH, the library of "missing" Haskell code. Now including support for shell globs, POSIX-style wildcards and more. Check here for more details.

  • HAppS - Haskell Application Server 0.8 Einar Karttunen announced HAppS 0.8. The Haskell Application Server version 0.8 contains a complete rewrite of the ACID and HTTP functionalities. Features include:

    • MACID - Monadic framework for ACID transactions.
    • An HTTP Server (outperforms Apache/PHP in informal benchmarks).
    • An SMTP Server.
    • Mail delivery agent.
    • DNS resolver in pure Haskell
    • XML and XSLT. Separate application logic from presentation using XML/XSLT.
    • And more..
       More information on the 
       the HAppS page.

  • Index-aware linear algebra. Frederik Eaton announced an index-aware linear algebra library written in Haskell. The library exposes index types and ranges so that static guarantees can be made about the library operations (e.g. an attempt to add two incompatibly sized matrices is a static error). Frederik's motivation is that a good linear algebra library which embeds knowledge of the mathematical structures in the type system, such that misuse is a static error, could mean Haskell makes valuable contribution in the area of technical computing, currently dominated by interpreted, weakly typed languages.

  • Crypto-3.0.3. Dominic Steinitz announced Crypto-3.0.3, a new version of the Haskell Cryptography Library. Version 3.0.3 supports: DES, Blowfish, AES, Cipher Block Chaining (CBC), PKCS#5 and nulls padding, SHA-1, MD5 , RSA, OAEP-based encryption (Bellare-Rogaway), PKCS#1v1.5 signature scheme, ASN.1, PKCS#8, X.509 Identity Certificates, X.509 Attribute Certificates. See here for more.
