Accommodations grouping
by Joachim Breitner 05 Feb '10

05 Feb '10

Hi, I’d like to start planning my ZuriHac travel and accommodation, and I’m looking for people who’d like to share a room in one of the hostels (City backpacker or Youth hostel, I’m tending to prefer the Youth Hostel. They have room for four people). Also, is there someone traveling from Germany passing through Karlsruhe, and would like me to join (either by Train, so one can start early hacking) or by car? Greetings, Joachim -- Joachim "nomeata" Breitner mail: mail(a)joachim-breitner.de | ICQ# 74513189 | GPG-Key: 4743206C JID: nomeata(a)joachim-breitner.de | http://www.joachim-breitner.de/ Debian Developer: nomeata(a)debian.org

Lightning talks/demos at ZuriHac
by Johan Tibell 16 Jan '10

16 Jan '10

Hi all! We'll set aside some time (e.g. 30-60 minutes) on Sunday afternoon for lightning talks/demos. A projector and a whiteboard will be available. Registration is not required but feel free to drop us an email if you already know that you want to give a talk/demo. Since the hackathon is still two months away you've got plenty of time to wrap up your latest project, polish it during the hackathon and finally present it that Sunday. See you all in March! Cheers, Johan

Fwd: Haskell Hackathon in Boston January 29th-31st?
by Ravi Nanavati 23 Nov '09

23 Nov '09

Since this didn's seem to get to the hackathon list the first time, I thought I'd try again.... Thanks, - Ravi ---------- Forwarded message ---------- From: Ravi Nanavati <ravi_n(a)alum.mit.edu> Date: Sat, Nov 21, 2009 at 3:36 PM Subject: Haskell Hackathon in Boston January 29th-31st? To: hackathon(a)haskell.org, bostonhaskell(a)googlegroups.com, haskell-cafe(a)haskell.org Cc: Nirav Dave <ndave(a)csail.mit.edu>, Michael Pellauer <pellauer(a)csail.mit.edu>, Mieszko Lis <mieszko(a)mit.edu> After all of the fun I had at Hac Phi, I've been thinking for a while that it would be fun to organize a Boston hackathon (to have all of the hackathon fun without the long drive). After some recent chats with my MIT friends, it seems like the weekend just after IAP (January 29th-January 31st) might be a good one. I've created a page to start organizing this hackathon (which I'm calling HacBOS unless someone comes up with a catchier name) here: http://www.haskell.org/haskellwiki/HacBOS If you'd be interested in attending a Boston hackathon, please add yourself to the possible attendees list on that page. If the proposed weekend does NOT work for you, but you're still interested in attending a Boston hackathon please indicate what other weekends during MIT's IAP (January 4th-January 29th) might work for you. I'm looking forward to making HacBOS happen! Thanks, - Ravi Nanavati

Edinburgh Hackathon (Hac7) summary
by Dougal Stanton 28 Sep '09

28 Sep '09

It's been nearly a month now since the Edinburgh Hackathon (29 & 30 August), organised to coincide with the convergence of Haskellers arriving for the ICFP. My apologies for this very late summary! Eric Kow was the driving force behind this Hackathon, though I agreed to help out locally because I live in Edinburgh. We had trouble organising a good venue through a combination of university holidays and Edinburgh International Festival. We spent the first day camping out in a cafe. On the second day Graeme Hutton arranged for us to use an empty room in the bowels of the ICFP venue. If I remember well the first day was heavily Darcs-oriented, and there were interesting conversations on version control representation, conflicts, and the future of Darcs over breakfast. The staff at Henderson's Restaurant didn't seem to mind our impromptu geeky enclave, and we kept buying coffee to pay for our wifi usage. I'll let the other Haskellers explain in their own words what they were up to for the rest of the time. Maybe some of them have updates on where these projects have gone since then? "At the hackathon I started working on a small extension to the GHCi debugger. The goal of the extension is to allow the debugger to show the term representation of thunks where possible. Presently, to find out the value of a thunk in the debugger you must force its evaluation. However, this is not always desirable, especially if the thunk contains breakpoints, or if it diverges. In some cases it ought to be possible to extract source code information from a thunk and show that to the user. I didn't get very far in the implementation because I spent most of the time re-learning how the term printer in the debugger works (and chatting to other people)." -- Bernie Pope "I was continuing to work on my camp correctness proofs. In particular, investigating how best to handle symmetric lemmas, and refactoring the existing definitions and proofs." -- Ian Lynagh "I worked on fixing Solaris/SPARC port of GHC. It turned out to be a tedious header file related issue, not very interesting." -- Ben Lippmeier "I worked on the formlets (again), I released a version that doesn't add any functionality, it only solves a bug." -- Chris Eidhof "I worked on a feature to let darcs users more conveniently upgrade to the hashed repository format. I also had lots of interesting discussions with darcs users and hackers :-)" -- Eric Kow "I worked on analysing some darcs performance problems, fixing a couple of GHC bugs, and some discussion about packages." -- Simon Marlow "I (along with Benedikt Huber) worked on adding a 'cabal init' command which automates much of the work of cabalising a project (creating a .cabal file, a Setup.hs file, a LICENSE file, etc). It's not quite done yet but should be finding its way into the cabal-install HEAD soon! -- Brent Yorgey "I worked on the new hackage-server a bit. darcs get http://code.haskell.org/hackage-server/ live instance at http://sparky.haskell.org:8080/" -- Duncan Coutts Thanks everyone who took part and who supplied an elegant summary of their work that weekend. I hope you all had a good time! Cheers, D -- Dougal Stanton dougal(a)dougalstanton.net // http://www.dougalstanton.net

Edinburgh Hackathon round-up
by Dougal Stanton 31 Aug '09

31 Aug '09

Hello Haskellers, On Saturday & Sunday (28th & 29th August) we held a Hackathon in Edinburgh, before the ICFP got fully underway. If you were there, thank you for coming. We'll be writing a summary of what happened soon, and we'd love to hear what you did. If you started a new project or fixed some insidious bug, identified a major bottleneck or just enriched the testing structure around your chosen project, it would be great to know. Just a line or two is all we need! I am hoping that everyone who attended will see this message, as they must have seen Eric's original advertising emails. But please pass this message along if you know there's someone we missed. Cheers, Dougal -- Dougal Stanton dougal(a)dougalstanton.net // http://www.dougalstanton.net

by Eric Y. Kow 28 Aug '09

28 Aug '09

Dear Haskellers, Last minute reminder: We will be having a Hack Day in Edinburgh on Sunday 30 August (ICFP venue). That's this weekend! For the interested, we will also be meeting up the day before 09:30 Saturday 29 August just outside the RCPE (ie. the ICFP venue again). We'll have a quick wander and hopefully find some nice places to sit, chat and hack. On Sunday the real Hack Day begins at the ICFP venue, rooms 4/5. http://www.haskell.org/haskellwiki/Hac7 And for the interested, Brent says: > I'll be there Saturday morning---looking forward to meeting people! > > Also, I have purchased a ticket to hear a concert of some 16th-century > a capella 16th-century music at the Canongate Kirk at 5pm on Saturday: > > http://www.edfringe.com/ticketing/detail.php?id=13649 > > Just thought I'd mention it, so if there's anyone else coming to the > meetup day and 16th-century a capella sounds like your cup of tea, you > can get a ticket too and we can go together. Looking forward to seeing you, Eric PS. Bring a name tag if you've got one. There are about 15 people registered so far. It's not too late to register! (yes, you could also just drop by...) -- Eric Kow <http://www.nltg.brighton.ac.uk/home/Eric.Kow> PGP Key ID: 08AC04F9

Edinburgh Meetup (Sat 29 Aug) and Hack Day (Sun 30 Aug)
by Eric Kow 27 Aug '09

27 Aug '09

Dear Haskellers, Just a quick reminder that we will be having a Hack Day in Edinburgh on Sunday 30 August (ICFP venue). That's in two weeks! For the interested, we will also be meeting up the day before 09:30 Saturday 29 August just outside the RCPE (ie. the ICFP venue again). We'll have a quick wander and hopefully find some nice places to sit and chat, whip out the occasional laptop and fling a lambda or not being careful not to injure the passers-by. For more details, see http://www.haskell.org/haskellwiki/Hac7 And do send me an email if you're interested in attending. It'll help us to get an idea how many people will be there. See you soon! :-) -- Eric Kow <http://www.nltg.brighton.ac.uk/home/Eric.Kow> PGP Key ID: 08AC04F9

Hac phi roundup
by Brent Yorgey 29 Jul '09

29 Jul '09

Hi everyone! Thanks to all who attended Hac phi and made it such a success! I hope everyone had a great time writing code and meeting other Haskell hackers--I know I did. I'm planning to write a little round-up post on my blog and I'd love to include short descriptions of what projects people worked on. I remember what some people worked on but not everyone. So if you'd be so kind as to send me a one- or two-sentence description of what you worked on while at Hac phi, I'd very much appreciate it. Also, please send along any links to blog posts, pictures, etc. which I can include as well. thanks! -Brent

ICFP accomodation available!
by Duncan Coutts 23 Jul '09

23 Jul '09

All, I've (almost certainly) got a flat available from the 31st to the 5th which covers ICFP and the following conferences including HS, CUFP and the HIW. Unfortunately it does not cover the 30th for the hackathon. You'd need to make other arrangements. It's a 5 room flat so if we fill it every night then the cost is £27 per-person per-night. If you're on a tight budget then you can share a room. Apparently most of the rooms will take two people. Let me know if you are interested. Duncan
