changes to Developer Zone
by Joe Harrington Jan. 26, 2008

Jan. 26, 2008

I have reorganized and updated the Developer Zone page. I also edited down some of the text, hopefully without removing any information. My goal is to make clear how we operate, who is doing what, what status of each effort is, what help is needed, and whom to contact to volunteer. It can do all these things with your help. However, there is now a lot of FILL IN to be done. Please search for FILL IN and see if you can do so. Some of the names on the old page were several years old and I haven't seen many of those people on the lists for a long time. So, I've put those names at the bottoms of the sections with a note to move them up into the team lists if they are still active. I'll remove them completely in a couple of weeks if they're still there. I've also made notes ("FILL IN") asking teams to fill in information about what they do. Teams, this may be your best recruiting tool, so I hope you'll identify your leader(s) and anyone who has taken on a key area, as well as what it is that you do and how. If this information is somewhere else, such as in Trac, please link it. The more links into actual work areas the better. I've identified Travis as coding lead. I think there is a packaging lead but I don't recall offhand who that is (Jarrod?). Are there "official" doc and web leads? Thanks for your help in whipping the new page into shape. --jh--

scikits binaries, tarballs, etc...
by Matt Knox Jan. 25, 2008

Jan. 25, 2008

Has there been any decisions / discussion regarding a standard location for distributing binaries, tarballs, docs, etc... for various scikits? I see that the mlabwrap scikit has a sourceforge page, and the openopt scikit has a file attached to the wiki page. I would tend to lean towards having a unified sourceforge (or equivalent) page for scikits (similar to what the mingw project has for example: http://sourceforge.net/project/showfiles.php?group_id=2435). Also, while I'm on the topic of scikits... the first line of the scikits front page (http://scipy.org/scipy/scikits/wiki) says "This is a wiki meant for the "hard-hat" area of the SciPy? ToolKits?." To me this makes it sound like a "sand box" or play ground of sorts, which isn't necessarily reflective of all the scikits (well, maybe it is reflective of the current state somewhat, but probably won't be in the future). I'd vote for just chopping off that leading sentence completely because I don't think getting rid of it makes things less clear - and in fact makes it clearer from my point of view. - Matt

The future of the scipy.sandbox and a reminder of upcoming doc-day
by Jarrod Millman Jan. 25, 2008

Jan. 25, 2008

Hello, I started a blog, which has two posts about the NumPy/SciPy code sprint/strategic planning meeting early this month. It doesn't have very much content yet, but I thought it would be worth letting everyone know where it is: http://jarrodmillman.blogspot.com/ The most recent entry addresses some of the reasons we decided to retire the sandbox. I also created a ticket for removing the sandbox: http://projects.scipy.org/scipy/scipy/ticket/573 I will work on further documenting what went on at the sprint and some other things tomorrow during the first NumPy/SciPy doc-day. As a reminder, Friday's doc-day will be virtual where anyone with an internet connection can join in on the scipy channel on irc.freenode.net. Thanks, -- Jarrod Millman Computational Infrastructure for Research Labs 10 Giannini Hall, UC Berkeley phone: 510.643.4014 http://cirl.berkeley.edu/

timeseries moved to scikits
by Matt Knox Jan. 24, 2008

Jan. 24, 2008

The timeseries module has been moved to the scikits svn repository (http://svn.scipy.org/svn/scikits/trunk/timeseries) and removed from the sandbox. It installs as a scikits namespace package as per the scikits convention. The maskedarray branch of numpy (only available in svn) is currently required for the timeseries scikit. This requirement will go away once the maskedarray merging is complete and an official release of numpy has been made with the new masked array module. I'll try to whip up a quick page on the trac site for the timeseries module some time this week and port the existing documentation over to there. - Matt

Hum. This was for Bradford. In any case, if anyone has suggestions or ideas about the implementation details, please chime in !

scikits svn access
by Matt Knox Jan. 22, 2008

Jan. 22, 2008

Hi there, could someone grant me access to the scikits svn repository so I can begin porting the sandbox timeseries module to a scikit package? Pierre GM will also require access at some point too if you want to set that up at the same time. If I could also get access to the scikits trac wiki so I can create a page for the timeseries scikit, that would be greatly appreciated as well. I created an account on the trac site with the username "mattknox_ca", so if you can tweak the permissions for that account, that would be fine. Or if creating a new account is easier, that's fine too. Thanks, - Matt
