===================================================================== PyPy Leysin Winter Sprint (12-19th January 2008) ===================================================================== .. image:: http://www.ermina.ch/002.JPG The next PyPy sprint will be in Leysin, Switzerland, for the fifth time. This is a fully public sprint: newcomers and topics other than those proposed below are welcome. ------------------------------ Goals and topics of the sprint ------------------------------ * Like previous winters, the main side goal is to have fun in winter sports :-) We can take a couple of days off for ski; at this time of year, ski days end before 4pm, which still leaves plenty of time to recover (er, I mean hack). * the overall idea of the sprint is to continue working on making PyPy ready for general use. A few more specific tasks: - app-level ctypes: getting to a basically usable point would be really nice. - JIT: there is a long-standing timeshifter refactoring, towards making the JIT be more interpreter-like. Starting it during the sprint might be a good way to share some of the knowledge of how the JIT really works. Alternatively, we can work on supporting ootype in the timeshifter. - Testing: e.g. we run various nightly test runs but the results are not summarized in a single page yet. - LLVM: llvm 2 is now at version 2.1 and nicely stable again. Our llvm backend has improved in the last few months, but refactoring it together with the genc backend to share code more directly would be a nice task. * We are open to all sorts of other tasks during the sprint, just propose something. ----------------------- Location & Accomodation ----------------------- Leysin, Switzerland, "same place as before". Let me refresh your memory: both the sprint venue and the lodging will be in a very spacious pair of chalets built specifically for bed & breakfast: http://www.ermina.ch/. The place has a good ADSL Internet connexion with wireless installed. You can of course arrange your own lodging anywhere (so long as you are in Leysin, you cannot be more than a 15 minute walk away from the sprint venue), but I definitely recommend lodging there too -- you won't find a better view anywhere else (though you probably won't get much worse ones easily, either :-) I made pre-reservations in the Chalet, so please *confirm* quickly that you are coming so that we can adjust the reservations as appropriate. The rate so far has been around 60 CHF a night all included in 2-person rooms, with breakfast. There are larger rooms too (less expensive) and maybe the possibility to get a single room if you really want to.

There will be some Swiss-to-EU adapters around - bring a EU-format power strip if you have one. ----------- Exact times ----------- Officially, 12th-19th January 2008. Both dates are flexible, you can arrive or leave earlier or later. We will give introductions and tutorials depending on who needs them, either on the 13th or the 14th.
