New issue 806: Covering grid does not respect field_parameters
https://bitbucket.org/yt_analysis/yt/issue/806/covering-grid-does-not-res...
Matthew Turk:
Currently, the mechanism by which fields are chunked and whatnot in the covering grid does not respect passing field parameters down to the `_data_source`.

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?

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-longsta...
The discussion about the figure size is here:
https://bitbucket.org/yt_analysis/yt/pull-request/723/fixing-some-longsta...
As I mention in the PR description I'm willing to back down on this change
if the consensus is that this is a bad idea.
Matt has already come out against the change, but before I revert it I
wanted to bring it up here and get opinions from other people.
Thanks for your help :)

New issue 805: Install requirements don't mention "setuptools"
https://bitbucket.org/yt_analysis/yt/issue/805/install-requirements-dont-...
Erik Schnetter:
I just followed the instructions on <http://yt-project.org/#getyt> to download and install yt. I installed the prerequisites listed after the paragraph
{{{
To build yt, you will first need to install a number of Python and C libraries that yt uses for key functionality
}}}
but I still received an error message
{{{
$ python setup.py develop
Traceback (most recent call last):
File "setup.py", line 9, in <module>
import setuptools
ImportError: No module named setuptools
}}}
I found that installing the package "py27-setuptools" (I am using OS X with MacPorts) helped.
I suggest you list "setuptools" as prerequisite as well.
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 introducing yt 3.0, where everyone in attendance
either participates in the talk or acts as ambassadors. I want this
to be submitted to the general track. I do not have any particular
interest in acting as the primary presenter.
* Sprints! For sure.
* Possibly a talk submitted to the astro track about domain-specific
stuff, like Hilary's spectrum generator, or John's Chandra generator,
or the integration with Rockstar, or even AGORA.
* We should participate in the WSSSPE workshop, which will be on
Thursday afternoon. Looks like right now I'll be co-chairing this.
* We may consider submitting a poster in addition, which emphasizes
things like outreach using yt.
Here are my drafts of the sprint and talk abstracts. You should be
able to provide comments on them by right-clicking. If you want
direct edit privs, let me know.
https://docs.google.com/document/d/15BakPzOLdN6IIjx3jDFyD4Jg01ing1uQ9nIgK...
Options I think we should pass on:
* yt-centric tutorial: we will get to the point that I think this is
a good idea, but I don't think we'd get enough people signing up for
it.
* yt-BOF. It might be worthwhile to consider setting up a BOF for
data analysis of spatial data, though. (Not just GIS.)
I will be submitting a talk about ZeroPy as well.

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...
Britton Smith:
In the experimental bookmark, adding particle filters fails unless you specifically reference pf.h first. For example, the following script: http://paste.yt-project.org/show/4379/
results in this
```
#!python
Traceback (most recent call last):
File "test.py", line 12, in <module>
pf.add_particle_filter("co_star")
File "/Users/britton/Documents/work/yt/yt-x86_64/src/yt-hg/yt/data_objects/static_output.py", line 373, in add_particle_filter
used = self._setup_filtered_type(f)
File "/Users/britton/Documents/work/yt/yt-x86_64/src/yt-hg/yt/data_objects/static_output.py", line 386, in _setup_filtered_type
if not filter.available(self.derived_field_list):
AttributeError: 'EnzoDataset' object has no attribute 'derived_field_list'
```
However, this script works fine: http://paste.yt-project.org/show/4380/
The only difference is the addition of "pf.h" to line 12.
Hi Matt,
I already sent an email which has the subject “About YT Divergence and Vorticity Plots from Jia-hung” to your gmail account.
In the email, it includes my data and my several frontend files.
Any suggestion is welcome and thank you in advance for the help.
Sincerely,
-Jia-Hung

Hi Jia-Hung,
Interesting. With cell-centered data, it ought to produce correct results.
Would you be able to send me a small sample dataset (off-list) and I
can take a look? Or feel free to stop by our hangout at 11AM Eastern
and I can try it out there.
-Matt

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 the rest:
for bm in `cat b1`; do hg bookmark --delete ${bm} ; done
for bm in `cat b1`; do hg push -B ${bm} ; done
Note that there's probably a way to do it in a single pass with
multiple -B arguments, but I didn't.
-Matt
