Repo cleanup
by Nathan Goldbaum Aug. 10, 2015

Aug. 10, 2015

Hi all, I'd like to spend some time in the next week or two doing some cleanup and tidying up on the yt repo. This comes in two flavors: removing dead code and adding basic linting tests. Dead Code --------------- There are still a number of big chunks of legacy code in the codebase that aren't called by anything, including: * boolean data objects * reason / reason plot widgets (yt.gui) * two scripts in the top-level "scripts" directory (pyro_queue.py and yt_lodgeit.py) * the top-level "… [View More]

Nightly dev builds
by John Zuhone Aug. 5, 2015

Aug. 5, 2015

Hi everybody (but especially Cameron), A while back I set up nightly dev binary builds for Anaconda and PyPI wheels--a month ago they stopped because something was wrong with the machine (right now these are Mac OS X only). I've restarted them on a different machine. We now have binary Anaconda builds made every night from the tip of the dev branch for Python 2.7 and 3.4. I'll try to set up PyPI wheels, and also set up the Windows builds, sometime this week. The files are hosted here: http:/… [View More]

about alternative kernel functions
by Bili Dong Aug. 3, 2015

Aug. 3, 2015

Hi all, Currently in yt, only the default cubic spline kernel function is provided and used for the smoothing. I’m thinking about adding more kernel functions, providing the possibility to choose from them and also the possibility for the users to provide their own ones. In my own research, a quintic spline kernel is used, for example. So I guess this functionality might also be useful for other users. My current plan goes like this: 1. Add several common kernel functions besides the current … [View More]
