Neil Mitchell's Blog (Haskell etc)

The recent Hal2 meeting in Germany has now had some talks posted online. Only one is in English, but it's a nice talk on generic progra...

* Warning: Benchmarks are hazardous to your health, always misleading and usually wrong. I've been working on optimising Haskell with th...

About ten days ago, AngloHaskell 2007 took place. AngloHaskell was a unique meeting, in many respects. I thought it might be appropriate to...

I've been doing more work on my Haskell optimiser , and its going quite well. Previously I've been attempting to get some initial be...

Update: You can actually further optimise the example in this post, which is done in my IFL 2007 Supero paper, available from my website . H...

Haskell has great support for abstraction: small functions can be written which do one general thing. Haskell also has great support for com...

(Not a Haskell post, but I wish it was, I hate writing VBScript!) When writing code for someone else, on a money per hour basis, you have to...

I've just released my Uniplate library , which hopes to remove the boilerplate from Haskell programs. I try to keep my PhD research as p...

Lots of people have written clever things about writing monads - their mathematical structure, properties etc. I wrote a Test Monad for my F...

Finally, after over two years of work, I've released Catch ! I recommend people use the tarball on hackage . The manual has all the nec...

{- ICFP referees look away now -} I've proved that the central XMonad StackSet module is safe on several occasions, as the code keeps e...

I use both GHC and Hugs for my development work. I primarily work with WinHugs for development, then move on to GHC for deployment. Unfort...

* This is building on from last time . In particular, that means that all the same disclaimers apply. Having done "wc -c" as the p...

* As usual , I'm going to qualify this with "on one particular benchmark, on one particular machine, with one particular set of fol...

{- ICFP referees look away now. -} Dons recently asked me to look over the StackSet.hs module of XMonad , checking for pattern-match error...

As part of my work on Hoogle 4 I've been bashing my deferred binary library quite a lot. I encountered one bug which I hadn't cons...

I've done some more work on Hoogle 4, and can now create a database from a textual file, then perform text searches upon the database an...

I haven't done much on Hoogle 4 in quite a while, and since I keep telling people that various bugs will be "fixed in Hoogle 4...

At the moment I'm working on a boilerplate removal for Haskell, which is faster (runtime), shorter (code), more type safe and requires f...

Today on the Haskell mailing list, someone confused VBScript and VBA. Its not really surprising, the "Visual Basic" or "VB...
