Unusual problem.
by Maciek Fijalkowski 02 Jun '07

02 Jun '07

I want to wrap termios lib, also for RPython. everything works quite smooth except error reporting. termios.tcgetattr (and others as well) use termios.error for error reporting, which is exception which cannot be used in a translated version. Hence my ll_termios_tcgetattr raises OSError instead (it's not mentioned anywhere in documentation of termios library, nor present in any CPython tests, but well...) So than arises a problem - ll version rises OSError, while default one raises termios.error, which makes everything harder to test (ie the same RPython program behaves differently before and after translation). What is casual solution here? Also any magic wrapping doesn't work here, since termios is a builtin module. Cheers, fijal

by Jakub Gustak 02 Jun '07

02 Jun '07

I would like to organize mini sprint (2-3 days) in Wroclaw. It would be hold on Wroclaw University of Technology. There are possible two alternative dates: 2-3th June 16(15)-17th June It depends how fast we can organize ourselves. Is there anybody, who would like to participate? Cheers, Jakub Gutsak p.s. I have a feeling, that I spend too much time doing that kind of stuff instead of coding my project.

CFP 5th June for CC Camp [camp-orga@events.ccc.de: FINAL Call for Papers: Chaos Communication Camp 2007]
by holger krekel 28 May '07

28 May '07

Hello all, below is an invitation and CFP for the Chaos Computer Camp in August 2007 around Berlin. (extended) deadline for proposals is 5th June. Maybe I submit a py.execnet/higher level networking talk ("building a flexible and fast platform for computer viruses" or so) and co-submit a "PyPy" one - question being: do some of us maybe want to meet up there and sprint a bit? Seems one is giving talks in airport hangars, btw, ... best, holger ----- Forwarded message from camp-orga(a)events.ccc.de ----- Date: Wed, 23 May 2007 22:38:53 +0200 From: camp-orga(a)events.ccc.de To: hpk(a)trillke.net Subject: FINAL Call for Papers: Chaos Communication Camp 2007 X-Spambayes-Classification: ham; 0.00 [snip personalized prae-ambel] FINAL Call for Papers: Chaos Communication Camp 2007, Berlin Chaos Communication Camp 2007 "In Fairy Dust We Trust!" August, 8th to 12th, 2007 Airport Museum Finowfurt (Finow Airport) near Berlin, Germany http://events.ccc.de/camp/2007/ Final Call for Paper Deadline: June 5th 2007, 23:59 CET =Overview= The Chaos Communication Camp is an international, five-day open-air event for hackers, builders, and makers organized by the Chaos Computer Club (CCC). The camp provides a relaxed atmosphere for free exchange of technical, social and political ideas. Discuss, sunbathe, and enjoy camping with some of the most interesting people you might ever meet. And all that with internet, power, an abundance of weird self-made gadgets, and people willing to explain them to you, right next to your tent. The Camp area is themed as a starship launch site and split into various thematic villages organized by participating groups from all over the world. Have a look at the incredible new location, right next to an old Russian military airfield (we'll launch drones and UFOs - no kidding!). All this together with vintage MiG fighter planes the Soviet airforce left there when they left East Germany and helicopters, oh my! Two huge main hangars (room for 400 people each) will feature conference tracks with lectures and presentations, while workshops will take place in a central workshop area and in the various villages. To get a first glimpse of what to expect have a look at our self-organizing participants at the Camp Wiki: http://events.ccc.de/camp/2007/Villages. Furthermore there will be a hangar for not-so-lonely hacking nights and days together with hundreds of others, and a hangar featuring art and beauty created with or without a computer. Of course there will also be a lounge with nice electronic music, German beer, great food, and a choice of caffeinated hacker drinks. The conference languages are English and German. Don't worry about language issues though - the Camp is a truly international event! Everyone will be happy to communicate with you in the languages of the Internet - broken English and 1337speak. =Topics= In general, lectures and workshops dealing with technology, ethics, science, security, art, philosophy, politics, culture and cooking are welcome. The main theme of this year's camp is the world we want to live in tomorrow. Any cool tech, research, ideas, and presentations interesting to our audience, are interesting to us. And even beyond the presentations, the camp lives from participation, so bring those gadgets, Go boards, webapps, p2p-simulators, knitted hardware protectors, drones, and lockpicking sets, and expect people to come to you wanting to learn more. =Travel= For this year's Camp there's a special travel opportunity. The Hacker Foundation (http://hackerfoundation.org) has put together a package of nothing less than legendary proportions. For US$1337 (roundtrip from the US and Canada) or ???1337 (roundtrip from Europe) you get admission to both the Camp and the Defcon hacker conference in Las Vegas just a few days before the Camp, a flight from Defcon to Frankfurt (Germany) and from there directly to Finow Airfield on a specially chartered "Hackers on a Plane" flight. This offer includes optional accomodation at the Camp. See for yourself: http://www.hackersonaplane.info/ For general travel Information see http://events.ccc.de/camp/2007/Getting_there =Lecture Requirements= Lectures are expected to be highly relevant in practice or better be darn funny. Sales droids and PR-people have been known to disappear without traces on past events. Interactive workshops are welcome. Hands-on anything are even more welcome. Final presentations for talks should be up to 60 minutes, for workshops up to 60 or 120 minutes long. Additionally, a question-and-answer period will be provided. Follow-up discussions and hands-on workshops are strongly encouraged, there will be space for such activities available outside the main lecture shelters (if you don't prefer a nice sit-in on the grass in the sun). Audio and video recordings of the lectures will be published online in various formats. All material will be available under a Creative Commons licence allowing free non-commercial redistribution of the material as long as the original credit to authors and publishers is retained. =Submissions= All proposals MUST be submitted online using our lecture submission system at https://pentabarf.cccv.de/submission/Camp+2007 . Please follow the instructions given there. You can provide papers and slides for the digital conference pack upon submission. Please make sure your submission contains all information we need to review your talk and send us everything in one go. If you have any questions regarding your submission, feel free to contact us at camp-content(a)cccv.de but do NOT submit your lecture via e-mail. Accepted speakers are asked to hand in slides used in their talks. Please use a well-known format for your slides. =Dates and deadlines= We've already finished our first CFP. We offer a scheduled second deadline till June, 5th. Submissions received before June 5th, 23:59 CET, will be allocated to remaining slots. Notification of acceptance will be sent by June, 27th, or earlier. Early submissions will be treated with higher priority. ----- End forwarded message ----- -- merlinux GmbH Steinbergstr. 42 31139 Hildesheim http://merlinux.de tel +49 5121 20800 75 (fax 77)

Implementing R (GNU S) in PyPy
by Maurice Ling 21 May '07

21 May '07

Hi all, I'm attempting to implement a R (Splus language) interpreter in PyPy so that R statistical modules can be used in Python, as an alternative to R runtime + RPy platform. Currently, I have R language in EBNF, how do I go from here? Thanks in advance, maurice

Probably the simplest way to solve the problem is not to allow arbitrary objects to be thrown in RPython; I quick grep inside objspace/std and interpret didn't show any case in which this feature is used, and in any case it should be very easy to patch. Else, you could special-case the raise/except when using subclasses of Exception, and don't do the wrapping in those cases; of course you would have to be careful when catching all the exceptions, something like this: try: foo() except: bar() needs to be translated to: try { foo() } catch(Exception e) { // this is __builtin__.Exception bar() } catch(ExceptionWrapper e) { bar() } or something similar. I think we should really try to avoid ExceptionWrapper beacuse it's both ugly and probably veeery slow. ciao Anto

PyPy Europython talks?
by Beatrice Düring 15 May '07

15 May '07

Hi there Back from Japan and thinking a bit about Europython 2007. Submission deadline is closing in and I wonder if we are to do any PyPy talks at EP 2007? I would be prepared to do one PyPy talk on the methodology - such as an experience summary on how we worked with sprints etc.... What do we want to do on the technical side? Submission deadline 18th of May. Sorry to ask about this when I know many are exhausted and focused on finalizing the EU-review - but I felt the need to ask.... Cheers Bea

[ann] pypy EU project finishing up
by holger krekel 14 May '07

14 May '07

Hi all, puh! ... The 28 months of the PyPy[*] EU project period have been an intense experience on many levels. We wrote a summary of results, development methods and experiences here: http://codespeak.net/pypy/extradoc/eu-report/PYPY-EU-Final-Activity-Report.… and are now heading for the final review meeting in Bruxelles (31st May). Most involved people look forward to some resting and letting the dust settle before tackling next steps and sprints. best, holger [*] The PyPy project aims to generate flexible and fast Python Implementations for various target environments and provides largely re-usable capabilities for implementing other dynamic languages.
