Introducing Reason, a yt GUI
by Cameron Hummels 31 Mar '11

31 Mar '11

YT development team: We're happy to announce a new web-based GUI for yt called Reason (version five!). It incorporates the full functionality of yt as well as several additional features that should make using YT much more efficient and interactive. In particular, new users and users working on remote machines (e.g. kraken, ranger, pleaides, etc.) should find this new GUI very useful as it allows one to interactively manipulate and visualize non-local data. Reason operates by creating a portable webserver on demand, which loads a javascript page bridging to the yt/python interpreter. This page provides an interpreter interface, with identical yt functionality, where created images/plots are posted to the web interface. We're still experimenting with how to provide access to this, but it includes the ability to transfer and directly display images, display widgets for interactive data exploration, and save and load scripts between runs. To use Reason, you will need to have the ext-js and ext-slate-theme packages, now included with the current install script. You can also download these manually. Once installed, start it by simply running: $ yt serve If you are running locally and supply the -o option (yt serve -o), it will open up a web browser automatically. There is also a help button in the lower left of Reason with basic functionality explained. Keep in mind that this is a BETA sequence (projection doesn't work yet), but please check it out, play around with it, and report any bugs or desired features missing from it. --Cameron Hummels, Jeff Oishi, Britton Smith & Matt Turk

IRC

Hi all, I've set up an IRC channel on irc.freenode.net. It's called #yt, and I'm going to start sitting in it. You can join using Adium (on OSX) or irssi or something on Linux. I've also put up an IRC webchat frontend here: http://yt.enzotools.org/irc.html The Enzo workshop this week is using IRC and have found it (so far) to be pretty productive. I think we could give this a shot and see if it's worthwhile. If not, we can just let it be self-regulating. :) -Matt

treecode thoughts
by Stephen Skory 26 Mar '11

26 Mar '11

Hi All, Over the last two weeks I have been working on adding a treecode method as an option for calculating the gravitational boundedness of clumps. Now I can say that it's pretty much functional. I think there's at least one small optimization I can make before I am ready to merge & push it back into the mainline repo, but other than that I think things are pretty polished. In summary, for medium to very large sized clumps (in terms of number of cells), the treecode is showing it's usefulness. My tests are not complete, but the break even line with the standard opening angle (==approximation control) of 1.0, is about 100,000 cells. For example, a spherical clump with three levels and 120,000 cells takes 272 seconds with the O(N^2) method, 175 seconds with the treecode, and has a 0.05% error. One thought I have is whether or not the treecode should be a semi-automatic thing? As implied above, for small to medium clumps, the pure-C O(N^2) method is actually faster for several reasons. First, fewer data fields need to be generated. Second, small clumps will generally not benefit from the treecode method due to geometry, and the extra machinery of the octree slows it down, too. But for larger clumps, the treecode is clearly beneficial. The option to use the treecode would be a function of the number of cells in the clump. Thoughts? As I've written things presently, the treecode will not help for unigrid datasets because the octree refinement levels match the dataset it's built to mirror. I think it should be possible to mock up fake levels in such a way that would allow the treecode method to work with unigrid datasets. In fact, I'm already doing something vaguely like this but only for the levels that actually exist in the dataset. My question is, do we think it is worth it? My impression is that clump finding is mostly done on AMR datasets, and this would add a bit of complexity. It's hard to say if it would have any advantage for AMR datasets. I do need to do a bit of testing to make sure that my periodic changes work, but I don't foresee many problems with that. I've already started adding some stuff to the docs on this, and I can finish them once the issues above are settled. Thanks for any thoughts you can share!

Re: [Yt-dev] Request for Review: bootstrap script; also, new 'pasteboards'
by chris.m.malone＠gmail.com 23 Mar '11

Hi Matt, I took a look at the docs you coded up, and indeed there are some interesting features with BB. In particular, I thought the `bbforks` command sounded pretty cool - however, it appears I am missing the lxml.html package, which is needed to get this to work: --------------------------------------------------------------------------------------- [cmalone@xrb yt]$ hg bbforks using 'ChrisMalone/yt-hg' as repo name getting descendants list abort: lxml.html is (currently) needed to run bbforks --------------------------------------------------------------------------------------- I thought maybe it was perhaps a result of my BB repo not having any forks, so I tried yours: --------------------------------------------------------------------------------------- [cmalone@xrb yt]$ hg bbforks -n MatthewTurk/yt getting descendants list abort: lxml.html is (currently) needed to run bbforks --------------------------------------------------------------------------------------- Is this missing in the install, or is it something on my end?

I should chime in and say that my pasteboard page was not setup after the bootstrapp'ing - the page just 404'ed. To fix this I just did a test commit to the pasteboard yt pasteboard --desc="This is just a test" test.py and it worked fine. So, it _is_ set up with BB, as far as I can tell, but the page just shows up as 404 until something is checked in, or following Briton's elegant solution of just doing a 'hg push' Chris On Mar 21, 2011 4:03pm, Britton Smith <brittonsmith(a)gmail.com> wrote: > I had a similar experience to Chris's.

yt user survey 2011
by j s oishi 22 Mar '11

22 Mar '11

Hi All, We'd like some feedback on your use and your opinions about the future of yt. It's really short, and no questions are mandatory, so feel free to fill in as many or as few as you'd like. Please visit https://spreadsheets.google.com/viewform?formkey=dGlFazdOcUtFbHJLVU80a2NGM3… and answer away. The last user survey was really useful for us to help make yt-2.0 what it was. The future of yt is looking really bright, and we'd like to ensure it is as useful as we can make it. If you'd like to get involved at any point in the development process, feel free to email yt-dev, or any member of the dev team individually. Thanks, and we look forward to hearing from you! Jeff

Request for Review: bootstrap script; also, new 'pasteboards'
by Matthew Turk 21 Mar '11

21 Mar '11

Hi all, Last week we had a conversation about a bootstrap script, where the feel of the room was either lukewarm or positive. Mostly people seemed to think it was ill-motivated or would take too many liberties. Over the last week, in the evenings etc I've created a bootstrap script for development, which overall I think is pretty well-motivated. The script accomplishes the following things, each of which requests for confirmation before going on. It uses a modified iniparse library so that any modifications to any ini files are made in a non-destructive manner. It accomplishes these tasks: 1) Ensure username is set up in ~/.hgrc 2) Ensure that the cedit and hgbb are enabled 3) Asks for and if needed creates a username on BitBucket 4) Sets up hgbb 5) Creates a pasteboard repository The diff is here: https://bitbucket.org/yt_analysis/yt/compare/MatthewTurk/yt..default You can pull from my repo: hg pull https://bitbucket.org/MatthewTurk/yt/ (But note the comment below about yt-supplemental) There are a couple things in this: * I wrote up something called a "pasteboard" this last week for more permanent mini-pastes of info. This uses mercurial to create/destroy items in it. You can see some examples here: http://matthewturk.bitbucket.org/ http://jsoishi.bitbucket.org/ http://samskillman.bitbucket.org/ This was born out of the SFLC thing that happened on the mailing list, when Sam emailed his script. I thought, wouldn't it be nice if we were older, and we had a pasteboard that was persistent, with descriptions, which we could programmatically upload/download from. This adds the new commands: yt pasteboard --desc="Something" some_file.py yt pastegrab PASTE_ID USERNAME This automatically tosses it up. You get embed codes and some highlights, but it's just easier to keep these things around than the pastebin. * The idea of enabling hgbb, cedit and ensuring a bitbucket user is because I am of the opinion we should make it easier to fork the repository to make changes. If those three are enabled, I believe a command-line forking, editing of sources and so on, are all within our reach. * This bootstrap script requires that the yt-supplemental repo be checked out in ${YT_DEST}/src/ . This repo is actually kind of cool, in that it is a subrepo setup, and it pulls in a couple external libraries that we can maintain. Right now it grabs the docs, the cookbook, and the extensions mentioned above. This repo is now pulled in the current install_script.sh. Anyway, I am submitting this to the list to get some review. There may be errors, but I have tested it quite a bit. It also informs the user of what it's about to do and requires the user hit enter. At one point it even asks for a yes or no. The reason I am interested in this is that I think the idea of bootstrapping people into a development environment is, generally, a good idea. Particularly because some things -- like the pasteboard, like forking, like contributing changes -- should be made really easy and have the potential for a very high payoff. I hope I've motivated things a bit better. I was hoping that before I merged it I could get someone else to read it over, maybe a couple people even to test it, and to get a good feel for whether this is worthwhile or whether I should pull these changes and just ignore the idea. What do people think? Thanks, Matt
