yt 3.1?
by Nathan Goldbaum
Hi all,
There have been a number of cool new features in the pull request queue
recently. Some of these have added new features and I think it might be
worthwhile to indicate that by bumping the minor version number on the next
release.
I think it would be a good idea to try to integrate the open PRs as well as
any that come in over the next couple of weeks that can be reviewed, call
it yt 3.1 and release on or around Dec. 1. This will mean generating a
proofread docs build and perhaps a few days of low-hanging issue triaging.
I'd nominate John ZuHone to send out the release email to recognize the
hard work he's been putting in recently.
Just an idea, but I've tried to include specifics as a basis for further
discussion. What do you all think?

Issue #930: np.concatenate fails for YTArrays (yt_analysis/yt)
by Douglas Rudd
New issue 930: np.concatenate fails for YTArrays
https://bitbucket.org/yt_analysis/yt/issue/930/npconcatenate-fails-for-yt...
Douglas Rudd:
YTArrays cannot be compared using numpy functions like intersect1d because np.concatenate either fails (for dimensional arrays) or for dimensionless arrays it produces a YTArray object where the units attribute is `None` (which then fails in `__eq__`, `__lt__`, etc).
This may already be known and may be unfixable (due to the way numpy implements concatenate)...
```
#!python
import yt
import numpy as np
A = yt.YTArray(range(10))
B = yt.YTArray(range(10))
np.intersect1d(A,B)
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)

Notebook progress bar?
by John ZuHone
Hey all,
I know we nixed the previous notebook progress bar because it was really bogging things down—but it would be handy to have one, and there are some ASCII-only implementations that probably won’t use as much memory.
Any thoughts? I’d be happy to look into it myself.
Best,
John

Hi Sam,
(Moving over to yt-dev)
What do you think the major reasons to hold off on merging are?

Issue #929: ProjectionPlot.set_log fails for radio fits datasets (yt_analysis/yt)
by Kacper Kowalik
New issue 929: ProjectionPlot.set_log fails for radio fits datasets
https://bitbucket.org/yt_analysis/yt/issue/929/projectionplotset_log-fail...
Kacper Kowalik:
Following script:
```
#!python

from yt.frontends.fits.misc import ds9_region
ds = yt.load("radio_fits/grs-50-cube.fits", nan_mask=0.0)
region = 'galactic;box(+49:26:35.150,-0:30:04.410,1926.1927",1483.3701",0.0)'
box_reg = ds9_region(ds, region)
prj = yt.ProjectionPlot(ds, "z", ["temperature"], origin="native",
data_source=box_reg, weight_field="ones") # "ones" weights each cell by 1
prj.set_log("temperature", True)
```
fails with rev: 297789d10298, yielding:
```

Fwd: Mercurial & SSL & POODLE,
Mercurial 2.7 and 2.7.1 and SSL error: sslv3 alert handshake failure
by Matthew Turk
FYI -- this may explain some issues last week.
---------- Forwarded message ----------
From: Mads Kiilerich <mads(a)kiilerich.com>
Date: Mon, Oct 20, 2014 at 2:22 PM
Subject: Mercurial & SSL & POODLE, Mercurial 2.7 and 2.7.1 and SSL
error: sslv3 alert handshake failure
To: "mercurial(a)selenic.com" <mercurial(a)selenic.com>
The recent POODLE story has raised the awareness of the problems with
old SSL versions. It might make sense to take the opportunity to
disable SSLv3 on web servers hosting Mercurial repositories.
Note however that there was a client side bug in Mercurial 2.7 and
2.7.1 that made it use SSLv3 without considering more recent versions.
Trying to connect to servers without SSLv3 with these Mercurial
versions will fail with something like:
abort: error: _ssl.c:507: error:14094410:SSL
routines:SSL3_READ_BYTES:sslv3 alert handshake failure
or if using TortoiseHg:
SSL error: sslv3 alert handshake failure
The solution is to upgrade Mercurial (or TortoiseHg) to a more recent version.
