Issues to Trello?
by Matthew Turk
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.

Splitting a compound unit into its atoms
by John ZuHone
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?

yt-3.0 two heads
by Michael Zingale
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.

Issue #912: Be careful about "thermal energy" uses in yt (yt_analysis/yt)
by Chris Malone
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."

Issue #909: calculate_isocontour_flux function raises error in parallel analysis interface (yt_analysis/yt)

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.
