Datadex
by Matthew Turk March 17, 2014

March 17, 2014

Hi all, I just saw this neat project on the Mozilla Science Lab etherpad for their call this week: http://datadex.io/ I think we should consider exploring it as a replacement for the data hub, once our AWS time goes away. Anybody feel like spinning up an instance? -Matt

Change the default plot size?
by Nathan Goldbaum March 17, 2014

March 17, 2014

Hi all, I recently opened a PR that fixes a number of bugs in yt's plotting code. Hopefully this will fix many common visual issues that show up in yt plots. As part of the PR I decided to change the default size of yt plots from 8 inches to 6. My justification is that the current default will create a plot that overflows an IPython notebook output cell, particularly on small displays. The PR is here: https://bitbucket.org/yt_analysis/yt/pull-request/723/fixing-some-longstand… The … [View More]

SciPy abstract submission
by Matthew Turk March 14, 2014

March 14, 2014

Hi everyone, The (nominal) due date for submissions for SciPy2014 is next Friday: https://conference.scipy.org/scipy2014/ . I think we should aim to have a strong presence there -- I've heard from a couple people they plan to be there, which is *awesome*. For various reasons, I am only going to be traveling to the yt workshop in Santa Cruz and SciPy for a little while, so I am planning to be there the entire duration. There are a few things I think we should consider: * A joint talk … [View More]

Hi all, Just wanted to make sure everyone had an opportunity to comment on and look at these pull requests: https://bitbucket.org/yt_analysis/yt/pull-request/719/adding-some-species-h… https://bitbucket.org/yt_analysis/ytep/pull-request/34/proposed-names-for-s… They propose new naming schemes for species fields, and then implement them for Enzo. You can see the translation table in the enzo/fields.py file. -Matt

New issue 803: Particle filters cannot be added without referencing pf.h first. https://bitbucket.org/yt_analysis/yt/issue/803/particle-filters-cannot-be-a… Britton Smith: In the experimental bookmark, adding particle filters fails unless you specifically reference pf.h first.

Cleaning up my bookmarks
by Matthew Turk March 13, 2014

March 13, 2014

Hi all, Now that all the main differences and changes and whatnot are merged in, I've decided to clean up my bookmarks. In case anybody else wants to do the same, here's my procedure. First, I collected all the names of non-head bookmarks: hg log -r "bookmark() and not head()" --template "{bookmarks}\n" > b1 I also backed up the full log output, just in case: hg log -r "bookmark() and not head()" > b1 I edited this because there were a few I didn't want to delete. Then, I deleted … [View More]
