CamHac

Haskell Hackaton in Cambridge, UK, August 12-14, 2011

About

Come and spend a weekend in Cambridge hacking Haskell code in great surroundings with fantastic company! Haskell Hackathons are a tradition where everyone is welcome; we get together, work on projects with others or just do your own thing, the overall goal being to improve the Haskell ecosystem.

CamHac will be held from 12-14 August 2011, at Homerton College in Cambridge. As with previous Hackathons, all are welcome -- you do not have to be a Haskell guru. All you need is a basic knowledge of Haskell, a willingness to learn, and a project you're excited to help with (or a project of your own to work on).

There will be lots of hacking, good food, and, of course, fun!

• Organiser: Simon Marlow (JaffaCake on IRC)
• Mailing list: hackathon@haskell.org
• IRC channel: #ghc on FreeNode

Many thanks to Microsoft Research Cambridge for agreeing to sponsor the event.

Venue

We're in the Leah Manning Room of Homerton Conference Centre. It is about 15 minutes walk from the train station, and Cambridge town centre is about 30 minutes walk.

Times:

• 0900: arrive any time from 9am, coffee and snacks will be available until 1000. Make sure you pick up your name badge and wifi details from the registration desk on arrival.
• 1045: break (coffee/tea, biscuits)
• 1230: lunch
• 1500: break (coffee/tea, cake)
• 1730: finish (we might be able to extend this a little if necessary)

There will be WiFi access, you will be given details when you arrive. We've been told that extra WiFi has been installed in the meeting room for us.

There will be a projector for giving talks/demos. We will probably reserve a part of the time for talks and demos.

Food

Tea and coffee will be supplied. We will have to go out to find lunch, but there are various places to eat and buy food at the Cambridge Leisure Park a few minutes walk towards Cambridge town centre. In the evening we will probably head towards the town where there are plenty of good restaurants.

We have been advised that only food provided by or purchased from Homerton College can be consumed on the premises.

Local arrangements

Getting to Cambridge

By Plane

• Stansted Airport: Stansted is the nearest of the London-area airports to Cambridge. It is mostly served by flights to and from mainland Europe, Ireland, and elsewhere in the UK. By train it is about 30 minutes to Cambridge, bus about 1 hour.

• Heathrow Airport: Heathrow is the principal London-area airport and one of the busiest in Europe with a wide range of national, European, and international services. By train it is about 1h30 to 2h to Cambridge (Heathrow Express is faster but more expensive).

• Gatwick Airport: Gatwick is the second "London" airport with a wide range of national, European and international services. By train it is about 2h to Cambridge.

• Other airports: Luton Airport, Norwich airport, and Southend airport are other regional airports in the East Anglia region. If you use these, car or taxi is the best option for travel to Cambridge.

Trains from London

London has two train lines into Cambridge, London Kings Cross and London Liverpool Street. There is a regular service on both lines and duration is under an hour on the direct trains. Go to National Rail to check train times.

You can usually buy tickets at the station both at a ticket machine or a staffed counter. You usually will not be able to buy tickets on the train without paying a fine. Tickets can be cheaper if you buy off-peak and return trip. Off-peak tickets are usually valid on weekends and after 10 a.m. on weekdays. Make sure, though, to check National Rail for which trains are eligible for off-peak tickets.

Getting to the venue

Walk from the train station (about 15 minutes)

Accommodation

VisitCambridge: Where to Stay in Cambridge

The nearest hotels to the venue seem to be:

• Travelodge (Cambridge Central) is just a few minutes walk from the venue. It is currently charging £65.80 per night for 11-14 August.
• Helen Hotel
• Bridge Guest House
• Fairways Guest House
• Abbeyfield Guest House
• Rock View Guest House
• Alington House Guest House

If you contact any of the above and find they're booked up, please remove them from the list.

Microsoft Research recommends the following hotels to visitors, these are closer to the city centre but are probably a lot more expensive than those above:

• Crowne Plaza Cambridge
• De Vere University Arms

Projects

Use this space to list projects you are interested in working on, and add your name to projects you are interested in helping with.

• General hacking away at Snap Framework (exact goals TBD), perhaps adding/improving documentation/tutorials at the same time. (Jurriën Stutterheim, Twey)
• Darcs
• Something games/3d related? (Stephen L)
• LambdaCube 3D engine (Csaba Hruska)
  • Discussion about graphics pipeline DSL
• Designing/proposing/implementing a new low-level network package, similar in role to 'network' itself (Ben Millwood, Twey)
  • See also User:benmachine/New network package
• Writing a library that implements the ideas of Typing Haskell In Haskell to type-check, say, a haskell-src-exts AST (Ben Millwood, Stijn van Drongelen)
  • I've been advised that THIH is actually quite old, and I might want to find a different base to work from. Any input appreciated. --Ben
    • Use a constraint-based approach, like the monadic constraint library that was presented at Anglohaskell the other year. Much more pleasant. --Philippa
    • Since haskell-src-exts includes GHC-specific extensions, why not round-trip via the GHC AST? That could also be used by other tools. --Nominolo
• wxHaskell (Maciek Makowski)
• System.Process: Provide a way to send arbitrary posix signals to a ProcessHandle. Matthiasg 20:56, 20 June 2011 (UTC)
• Have an option to avoid using package.cache, because it makes working with Open Embedded quite hard. Matthiasg 15:57, 27 June 2011 (UTC)
• Hackage 2 (Ben Millwood)
• Data.Text (Jasper Van der Jeugt)
• unordered-containers (Johan Tibell)
• I probably deserve a real kicking for this, but: a TeX replacement. Specifically, embed TeX in Haskell so you can both parse down to its semantic layer and manipulate the semantic layer stuff (which is still pretty-printable back out to TeX as a bunch of primitives and not-so-primitives). Got a bunch of ideas for this, but it's mostly an itch I just got - am currently reading through the TeXbook to check I've understood how TeX itself works sufficiently though, and who doesn't want a backwards-compatible-including-extensions TeX replacement with better syntax, typechecking and the potential for better debugging? --PhilippaCowderoy 22:04, 3 August 2011 (UTC)

Talks/demos

If you have a talk or demo you want to give, add your name to the list below. Let's restrict these to short slots (say 20 mins max). Tentatively we'll have a session of talks and demos on Saturday afternoon, but we can always move things around if necessary.

• add your name and talk/demo title here...
