Hi all,
What would you all think of having new issues reported to Trello? I
would worry about issues then being updated in two places (or one
instead of two), but it feels like Trello is just a way more natural
fit for how we work than the BB issue tracker. Maybe I'm wrong on
that...
Anyway, we can have them forwarded via email, or use one of the
connectors out there to have them go there. But maybe it would just
fragment things.

This should be obvious to me, but I can't seem to figure it out.
Is there a way to take a compound units expression like:
dyne*cm**2/g**2
and split it into its constituent parts, so that I have a list like this:
[dyne, cm, g]
and maybe even containing the information about the powers?
At the moment, in the yt repo, we have two heads on the yt-3.0 branch -- is
that what we want? I try merging them in my local copy and it doesn't go
cleanly.

New issue 914: draw_domain with specified north_vector
https://bitbucket.org/yt_analysis/yt/issue/914/draw_domain-with-specified...
Sam Skillman:
Seems to be broken for non-cubical domains. Will update with an example when I get a chance. Something is either transposed or not done correctly during the projection

Hi all,
Chris Malone just opened a pull request to improve our documentation of PR
workflows on bitbucket, particularly how to have multiple simultaneous pull
requests open.
https://bitbucket.org/yt_analysis/yt/pull-request/1227/docs-on-handling-m...
The PR looks good to me right now, but I'd very much appreciate it if an hg
novice could look it over and point out anything that's confusing.
Thanks for your help!

New issue 912: Be careful about "thermal energy" uses in yt
https://bitbucket.org/yt_analysis/yt/issue/912/be-careful-about-thermal-e...
Chris Malone:
This came up in the comments of a PR. In essence, @mzingale summarized the issue quite well:
"I'm a little concerned about the name thermal energy. We don't necessarily have thermal energy easily available [in Maestro]. We have internal energy, or gas energy, but when we are very degenerate, the internal energy is not thermal, so the name thermal energy is misleading and perhaps dangerous. Since this is a yt convention, maybe for these codes we should return an error if thermal energy is requested and perhaps we can define a more code-agnostic general name for the gas internal energy that can be used in situations where thermal energy is wrong."
New issue 911: Enable the same projection "methods" for OffAxisProjectionPlot as available for ProjectionPlot
https://bitbucket.org/yt_analysis/yt/issue/911/enable-the-same-projection...
Cameron Hummels:
Right now, OffAxisProjectionPlot only allows weighted and unweighted 'integration' plots, but not 'sum' or 'mip' plots in the same way that ProjectionPlot does.
New issue 909: calculate_isocontour_flux function raises error in parallel analysis interface

Nathan Goldbaum:
The following test script:

dd = ds.all_data()
dd.calculate_isocontour_flux('density', 1e-23, 'x-velocity', 'y-velocity', 'z-velocity', 'density')
```
raises the following error:
```

I think the parallel analysis interface should be using the chunking system here, but I'm not sure. I also a little mystified why the unit tests for this function didn't pick this up.
