Issue #879: yt-3.0 docs website (yt_analysis/yt)
by Kenza Arraki Aug. 15, 2014

Aug. 15, 2014

New issue 879: yt-3.0 docs website https://bitbucket.org/yt_analysis/yt/issue/879/yt-30-docs-website Kenza Arraki: When I visit [3.0 docs](http://yt-project.org/docs/3.0/) with too small a browser window the top options bar collapses into a smaller drop down website. If I click on this button, the menu appears and quickly disappears again before I am able to see or select an option. I have found this using Chrome and Firefox on OSX and Firefox on Ubuntu.

Next iteration of rockstar development
by Matthew Turk Aug. 14, 2014

Aug. 14, 2014

Hi all, I've added a card for the next steps for Rockstar here: https://trello.com/c/lqmt2hEz/40-use-yt-fof-rockstar-groups This essentially reduces yt's interaction with Rockstar to just calling "groupies" which does not require any communication on Rockstar's part. The process is now to use yt to identify FOF nodes and then filter them with Rockstar. (In my head, for some reason, I keep thinking of this as "rocketeer.") In that card is a pastebin that includes a working script for doing … [View More]

problem with disk data container and related fields in yt-3.0
by Britton Smith Aug. 13, 2014

Aug. 13, 2014

Hi all, Some issues seem to have cropped up in the disk data container in yt-3.0. I made a disk object in a periodic simulation in the following way: http://paste.yt-project.org/show/5021/ I then made a project of the "cylindrical_z" field, which yielded the following: http://i.imgur.com/0XSv5Zs.png For reference, the domain is ~45 Mpc in length on a side, so the sphere should be just the object at the bottom, extending a little less than halfway up. I don't know what that top part is … [View More]

ARTIO time mapping
by Douglas Harvey Rudd Aug. 10, 2014

Aug. 10, 2014

Hi all, I've been asked by someone who is using yt to analyze ARTIO data (yes! they exist!). They're interested in the distribution of star particle creation times (BIRTH_TIME in the internal code nomenclature). There is code to do a conversion to age that seems to have been borrowed from the ART frontend, but it's incomplete and incorrect for z > 0, so I'm porting over the c code that we use internally in ART(IO). That's all fine and good, but there's still a residual issue with … [View More]

coLaboratory Chrome App
by Sam Skillman Aug. 8, 2014

Aug. 8, 2014

Hi all, Some of you might be interested in a few news bits today: http://googleresearch.blogspot.com/2014/08/doing-data-science-with-colabora… and http://www.symmetrymagazine.org/article/august-2014/open-access-to-the-univ… What's even cooler than the fact that you can now load up an ipython notebook that runs sandboxed in your Chrome browser is that because Matt is the one compiling all these python tools into the Chrome app, we went ahead and included a very recent version of yt 3.0! Then … [View More]

Issue #878: PlotWindow should fail more gracefully when plotting particle fields (yt_analysis/yt)
by Nathan Goldbaum Aug. 8, 2014

Aug. 8, 2014

New issue 878: PlotWindow should fail more gracefully when plotting particle fields https://bitbucket.org/yt_analysis/yt/issue/878/plotwindow-should-fail-more-… Nathan Goldbaum: Right now plotting a particle field leads to a crash in the frontend's I/O subsystem when it tries to treat the particle field as if it were a mesh field. We should check whether we're actually plotting a mesh field and then crash gracefully with a nice error message if we detect a particle field. Responsible: ngoldbaum

Move sanitization routines into coordinate handlers?
by Matthew Turk Aug. 5, 2014

Aug. 5, 2014

Hi all, especially Nathan, What do you think about moving the functions: get_sanitized_center get_sanitized_width get_window_parameters get_oblique_window_parameters into the coordinate handler (ds.coordinates)? This would make it easier to implement them more carefully and clearly for the different coordinate systems, like spherical, cylindrical, etc. -Matt

Anaconda packages have been updated
by Nathan Goldbaum Aug. 5, 2014

Aug. 5, 2014

The yt conda packages that Continuum Analytics builds for us as part of the anaconda python distribution have just been updated for yt 3.0. Most importantly, there is now a 64 bit Windows build along with the OSX and Linux builds! Right now there are only 64 bit packages, but we should have 32 bit packages soon after fixing an issue that causes test failures on 32 bit builds of yt. If you use conda, you should be able to update yt with "conda update yt". Thanks to Aaron Meurer for helping … [View More]
