I spent some time today trying to talk to a MySQL database server from a piece of middleware I’m writing in Haskell.

Here’s a useful little tip if you need to use hg convert to generate a stripped-down copy of a Mercurial repository.

Thanks to diligent work by Johan, our new I/O manager is ready to merge into the main GHC tree.

After a few months of blissfully doing precious little hacking in our spare time, Johan and I have returned to work on the new event manager for GHC.

In my first of this pair of articles, I laid out some of the qualities I’ve been looking for in a parsing library.

My goal in working on the new GHC I/O manager has been to get the Haskell network stack into a state where it could be used to attack high-performance and scalable networking problems, domains in which it has historically been weak.

While I’ve been in my corner hacking on low-level Haskell nonsense, apparently someone figured out how to make the internets more better.

Over the past couple of weeks, I have been working with Johan Tibbell on an event library to use for replacing GHC’s existing I/O manager.

…if the world of blogging about software had by now developed some kind of a tradition of critical analysis?

I’m pleased to announce the availability of version 0.2 of my criterion library for Haskell performance evaluation.

I’m pleased to announce the availability of version 0.5 of text, a library that provides fast Unicode text handling for Haskell.

And has prettier charts, too, thanks to a patch from Tim Docker.

I’m pleased to announce the availability of criterion, a new library for measuring the performance of Haskell code.

Thanks to the tireless work of Malcolm Wallace, all of the video from CUFP now appears to be up up Vimeo, including the keynote talk I gave.

I just released version 0.3.3 of the Haskell statistics library, which contains a very fast pseudo-random number generator.

Malcolm Wallace has very kindly put a lot of work into publishing video footage from all of the talks at last week’s Haskell Implementor’s Workshop.

A few weeks ago, I decided that I’d like to focus for a while on getting a 1.0 release of the Haskell text library ready.

Several months ago, I wrote an article on evaluating revision control systems.

I was delighted to be invited to give the keynote talk at this year’s CUFP workshop in Edinburgh.

I spent a little time earlier today clarifying the Fedora project’s support for the Haskell Platform.

Now that I’ve got the DEFUN 2009 schedule sorted out (you are coming, aren’t you?)

I just released version 0.2 of the Haskell text library that I announced back in February.

I had a wonderful time at the Bay Area Erlang Factory this morning, speaking to an Erlang audience about the different perspective that Haskell brings to functional programming.

ACM SIGPLAN 2009 Developer Tracks on Functional Programming http://www.defun2009.info/ Edinburgh, Scotland, September 3 and 5, 2009 The workshop will be held in conjunction with ICFP 2009 http://www.cs.nott.ac.uk/~gmh/icfp09.html Important dates Proposal…

If you’ve looked at the Mercurial book site in the past 24 hours, you’ll have noticed that both its look and the name of the book have changed.

I think that this video is remarkably beautiful.

On behalf of the Data.Text team, I am delighted to announce the release of preview versions of two new packages: text 0.1 Fast, packed Unicode text support, using a modern stream fusion framework. text-icu 0.1 Augments the text package with comprehensive…

My friends at Erlang Training and Consulting are running an organising an event in Palo Alto at the end of April: Erlang Factory.

Via the ever industrious Danny O’Brien, we bring to you the Electronic Frontier Foundation’s end-of-year animation.

Twitter has become quite the hotbed of chatter about functional programming over the past few months, as a substantial number of pretty well known FP people have either been present all along or have signed up recently and started following each other.

A few months ago, I tore the A4 pulley tendon in my right ring finger in a climbing accident.
