New issue 1041: Rockstar frontend counts extra files https://bitbucket.org/yt_analysis/yt/issue/1041/rockstar-frontend-counts-ex… Britton Smith: The Rockstar frontend counts files by globbing prefix*, when it should be prefix.*. For example, this means that counting files for the dataset halos_13.0.bin will also count files for halos_130.0.bin, halos_131.0.bin, etc. Responsible: brittonsmith

Stable release
by Nathan Goldbaum July 6, 2015

July 6, 2015

Hi all, A while back we were intending to backport bugfixes from the yt branch to the stable branch and then regularly issue bugfix releases. This hasn't happened, and new users in particular feel the pain this causes. Does someone want to volunteer to backport bugfix pull requests to the stable branch? It should be more or less automatic, although you will likely need to do it one pull request at a time, and it will be hard to review. This would be a great, relatively straightforward if … [View More]

code of conduct hangout
by Britton Smith July 6, 2015

July 6, 2015

Hi everyone, As per last week's meeting, I am now going to begin the process of incorporating astropy's code of conduct into yt's infrastructure. This will involve minor edits to make it specific for yt instead of astropy, adding it to various places (YTEP, website, developer docs), and such things. This is not a huge amount of labor, but enough that I would greatly appreciate some help. I think this could probably all be done in an hour or less with a small group of people (3-4 or so). If … [View More]

by Britton Smith July 6, 2015

July 6, 2015

Hi all, I took notes at last week's yt team meeting. As anyone who has seen a notebook from my school years can attest, I am a terrible note taker, so I apologize in advance for their being of poor quality. For what they're worth, they can be viewed here: https://docs.google.com/document/d/1ch_rVevHTWP6BQUKiumxnKeVp57jGcbfN7oTIDU… On the topic of team meetings, there was some discussion last week about how best to include everyone who wants to attend. For the next meeting, I will first put … [View More]

VR camera movement
by Cameron Hummels July 5, 2015

July 5, 2015

I've been thinking about the `rotate()`, `pitch()`, `yaw()`, and `roll()` camera functions in the new volume rendering PR, and I wanted to bounce something off of people. Right now, `rotate()` rotates the camera position about the pivot point of the focus point of the camera--it can make that rotation with respect to three vectors all centered on the focus point: * `pitch()` rotates up/down pivoting on the horizontal vector going through focus point * `yaw()` rotates left/right pivoting on … [View More]
