Joe, What is the URL for the original site now? It should be linked somewhere on the new site so we can go back and get stuff. The bottom of the ASP page (in Developer Zone) would be a good and obscure place, under Web Site. --jh--

The new SciPy.org
by Joe Cooper Jan. 31, 2006

Jan. 31, 2006

Hi all, As threatened, the new Moin wiki has taken over the SciPy.org site. The migration has proven even more complicated than anticipated (and I anticipated a lot of complexity), so some services remain on the old server as of this morning. This will be wrapped up later today, after I get some sleep. Some of the things that have gone well: - The wiki is great. Andrew and Oliphant and lots of others did a fantastic job on it. - Mailing list archive links have an accurate Moved Temporarily redirect (i.e. google links to scipy archives will continue to work). I need to hash out with Travis how he'd like to handle the mailing list archives going forward, as he wrote the scripts that integrated them into Plone, and obviously those aren't going to work in Moin. I wrote something in Perl in the meantime, but I imagine that'll go away as soon as Travis becomes aware of it. - It will be possible to redirect most "sections" of the old plone site to a similar section on the Moin site...I just need to figure out which sections from Plone apply to what in the Wiki. This will be a time-consuming thing, but is probably worth the trouble in order to keep some google links working reasonably well some of the time. Some things that remain outstanding: - Mail and list migration. I don't expect trouble with this, it just takes a long time, and requires attention to a lot of boring details. - Takeover of the old IP, so that DNS service for the "scipy.org" domain is taken over by the new server. This one is moderately tricky, since we have a half-dozen delegated domains for the other projects hosted on the server (ipython, neuroimaging, etc.). Those have to be merged back into the scipy zone. I'm sure there are problems somewhere...But it's running relatively well, with at least working content everywhere I thought to poke. Holler if you see anything glaringly stupid caused by the change. Thanks!

Let me know if there are any errors or omissions. I've also disabled (from non-developer view) the forums and trackers at the sourceforge site--there are folks who have been posting there, but no one is monitoring these tools. Please use the mailing lists for questions: scipy-user(a)scipy.org -- subscribe at http://www.scipy.net/mailman/listinfo/scipy-user scipy-dev(a)scipy.org -- subscribe at http://www.scipy.net/mailman/listinfo/scipy-dev and use the Tracker for issue/bugs/feature requests: http://projects.scipy.org/scipy/scipy Thanks, Travis p.s. Developers, please help move any relevant issues from sourceforge over to the developer tracker.)

should Int8 be UnsignedInt8 in misc/pilutil.py?
by Albert Huang Jan. 31, 2006

Jan. 31, 2006

Hello, pilutil.imread currently converts RGB images to arrays of signed integers. I think it should be unsigned integers instead. If you do an imshow(imread( ... ) ) on any brightly colored image, then all the RGB values > 127 get whacked. Also, it's probably not very intuitive to say that -1 is brighter than 127. The attached patch fixes it for me. I just changed all occurences of 'b' to 'B', but am not too sure what the effect is in toimage(). Regards, Albert

No time for SciPy release today
by Travis Oliphant Jan. 31, 2006

Jan. 31, 2006

I'm not going to have time to make a release of (full) SciPy today. It builds find out of SVN. I'm starting classes on Monday (and have to get back to the seven other things I've left holding while putting NumPy out) so I'm not sure how much time I'll have for it over the next few weeks. If somebody else wants to take a stab at making a release of (full) SciPy, I can point you in the right direction. -Travis

ASP, wiki, renaming Topical Software
by Joe Harrington Jan. 31, 2006

Jan. 31, 2006

Kudos to Andrew Straw and all web contributors! I'm looking forward to having a "no apologies" web site at scipy.org again. The new site is definitely ready. I've moved Web from the first to the last topic on the ASP page, leaving Documentation as the top focus going forward. I've linked the ASP page under Developer Zone. The page has two goals: to give thoughts on what needs to be done (the roadmap link), and to serve as a place for defining, organizing, and doing projects (the rest of the ASP page). The latter is a sort of topical "Who's Who", with topics being added, people listing themselves under the projects they're working on, and users/new helpers finding project leads. If nothing else, this should help reduce mailing list traffic of the "who is taking care of xxxx" sort. However, this page has only a fraction of active workers and projects listed. Is this because the old Plone site was annoying, or because people don't want to bother? Would it be better to have a page named "Who's Who" under Developer Zone, and link the ASP roadmap separately? The page isn't useful if people don't list themselves, so please do. There are several links that are now broken, or soon will be, from pages that don't appear to be migrated (Numeric Compatibility, Doc Tools, Tutorial). Is the first of these now irrelevant, or more properly a NumPy vs. Numeric rather than SciPy vs. Numeric issue? I hope the authors of these pages will migrate them. Some wiki questions: Why are h3 and h4 headings no different from h2? In several places, I had to say "http://new.scipy.org/Wiki/..." in order to get a link address to be hidden behind its text. Probably others had to do this as well, unless they figured out something I didn't. So, when the site goes live, these will all have to change. Can that be automated? Finally, I'd like to consider renaming "Topical Software". This page has a link to every Python package that is vaguely of use to scientists and engineers. It's also a top-level heading on the main page, and the heading isn't speaking to me (at least). Some ideas: Add-on Software Add-on Software Index Additional Software Additional Software Index Application Software but it isn't all really application software Application Software Index but it isn't all really application software Software Index not clear it's separate from SciPy Topical Software if it ain't broke... If there's interest in renaming, I'll put a renaming vote grid at the top of the Topical Software page. Let me know by private email if you agree it should be renamed. If I get 10 positive emails I'll hang a vote grid off the Topical page and send another email to the list. Again, many thanks to those who have contributed to new.scipy.org! --jh--

Scipy and event handling in differential equations
by Nils Wagner Jan. 31, 2006

Hi all, Has scipy.integrate.odeint a framework for event detection and handling ? I would be happy about a small python script illustrating this task and its solution. Thanks in advance. Nils Reference: http://www.mathworks.com/moler/odes.pdf pp.23--

Status of 1.0 release and website?
by Jonathan Taylor Jan. 31, 2006

Jan. 31, 2006

I am wondering what needs to happen before a 1.0 release of both numpy and scipy? Also... what is the current status of the new web site... it looks to me like it has basically all of the old content. Well at least the stuff that is not out of date. J.

SciPy migration underway
by Joe Cooper Jan. 30, 2006

Jan. 30, 2006

Hi all, As many of you know, there's been a lot of work going on on various aspects of the SciPy website--Andrew Straw and Travis Oliphant and many others have been working hard on the new Moin-based website, and it's looking really great. It has already proven to be a success in all of the ways that the Plone site has always failed (i.e. making it easy for people to get involved and contribute), and everyone concerned would now like it to be the official First Contact for anyone coming to SciPy. To that end tonight I will be making the final changes that moves the website, mailing lists and old archives and user lists, and everything else to the new server and the front page of scipy.org will be the new Moin wiki (http://new.scipy.org/Wiki for those who haven't seen it, but really want to see it even before the move takes place this afternoon). I'm putting forth an effort not to break anything in the process, but that's hoping for a lot when so many services and complicated redirects, proxy rules, and assorted stuff is involved. So, if you find any SciPy.org service is broken between now and tomorrow morning, don't be too surprised. If anything is still broken in the morning, please let me know about it, as it probably means I didn't notice. Anyway, just a heads up about the impending intermittent downtime of some or all of our services on SciPy.org during the next few hours.
