During this sprint we will also look at using LLVM JIT for our project.
What exactly we will do in Tokyo very much depends on who will
attend. So if you are interested please contact me beforehand so we
can make sure everyone will have a fun and productive time.

Tokyo PyPy Sprint: 23rd - 29th April 2006
The next PyPy sprint is scheduled to take place 23rd- 29th April 2006
(Sunday-Saturday) in Akihabara, Tokyo, Japan. We will together with
FSIJ (Free Software Initiative of Japan) aim to promote Python and
PyPy. We therefor invite Japanese hackers knowledgeable in Python to
join our sprint! We'll give newcomer-friendly introductions. To learn
more about the new Python-in-Python implementation look here:
For this sprint we are particularly interested in meeting and coding
on PyPy together
with interested Japanese Python hackers. Please register your
interest at pypy-sprint at codespeak.net
as soon as possible and we will help with any questions regarding
getting started, pointing
to relevant documentation etc.
The PyPy team is curious and interested in the experience of hacking
code for embedded devices
and would love to discuss and get feedback on optimisation efforts
and the current state of PyPy.
Goals and topics of the sprint
Possible suggestions for topics are:
- Work on gensqueak (our Squeak backend) or possibly other backends.
- Implementing Python 2.5 features in PyPy.
- Progress further on an 'rctypes' module aiming at letting us use
implementation of an extension module from the compiled pypy-c.
- Writing ctypes implementations of modules to be used by the above
- Experimenting and improving performance of our garbage collectors.
- Experiment with PyPy flexibility or other aspects of the
- Possibly experiment with writing modules translatable for use both
in PyPy and CPython.
- Whatever participants want to do with PyPy or particular areas
of PyPy (please send suggestions to the mailing list before to
allow us to plan
and give feedback)
Location & Accomodation
The sprint will be held at National Institute of AIST
(National Institute of Advanced Industrial Science and Technology,
http://www.aist.go.jp/index_en.html), Akihahabara (the technical
district in Tokyo). Yutaka Niibe is our contact person there,
helping with arranging facilities. Niibe is the chairman of FSIJ and
invited us to sprint in Tokyo and we are very grateful for the help
we have recieved so far.
The facilities we are sprinting in are located here:
The actual address is:
Akihabara Dai Bldg , 1-18-13 Sotokanda, Chiyoda-ku, Tokyo 101-0021 Japan
Hotel areas - we are recommended to book hotels in Ueno and Asakusa
from those areas there are only two metro stops to Akihabara. Please
hotelrooms in Tokyo are often very small.

Comments on the weather: In end April it is ca 20 degrees Celsius.
The public PyPy sprint is held Sunday 23rd - Saturday 29th April 2006.
Hours will be from 10:00 until people have had enough. It's a good idea
to arrive a day before the sprint starts and leave a day later.
cannot stay for the whole sprint - you are welcome even if you can
for a day or a few days.
Sunday: Starting at 10:00. This day is focused on getting to know
PyPy enought to
start to participate. We will hold a PyPy tutorial and an
Planning meeting for the work to be done during the week and grouping
of developers (pairs
or groups mixing new participants with core developers).
Dinner in the evening (Yutaka will arrange a place for us to go to).
Monday-Tuesday: Starting at 10:00 with status meetings. Possible
depending on the interest and progress of the various teams.
Wednesday: Breakday (coding is allowed although we recommend taking a
Thursday-Saturday: Starting at 10:00 with status meetings. Possible
depending on the interest and progress of the various teams. Ending
on Saturday with
a Closure session - summing of the work and planning work to be done
until the next sprint.
Network, Food, currency
We will have access to WiFi at AIST - please make sure you have wlan
Electricity outlets: 100V (adapters needed for european standard).
Currency is Japanese yen. There are Citibank cash machines that
accepts cash withdrawals from the major cards such as VISA and
But it is a good idea to bring cash.
Also note that cell phones (european) are not very compatible with
network. There are possibilities for 3G phones to hire a phone and
put your simcard
in there. At the airport (both Kansai and Narita) there are
information and places
were this can be arranged (to a cost of course).
Food: well - japanese food is great (wether it is sushi, sashimi,
tempura, sukiyaki, teriyaki....
Eating out is not that much differently prized
than any large european town. There are of course restaurants serving
other food than japanese (chinese, korean, McDonalds ;-).
Please also note that vegetables and fruit is quite expensive in Japan.
For more information - see tourist url:s above.

there! There also is a separate `Tokyo people`_ page tracking who is
already thought to come. If you have commit rights on codespeak then
