   Another Blabr dev here. This is a really nice blab. We'd targeted Blabr for scientific computing (and, in particular, for STEM and conceptual modelling), but you've demonstrated that it also works well for other kinds of online,

   Here's a way to use an iframe to embed a blab in a web page: https://news.ycombinator.com/item?id=10529079 For WordPress, you could use an iframe plugin.

    Thanks for this great question. To answer it, a good place to start is with why we wanted to build Blabr. Some months ago, we were working with interactive spreadsheets from the Space Math @ NASA website: http://spacemath.gsfc

    Thank you. Easily setting up "tunable" parameters (e.g., sliders) in a computation was a key requirement for Blabr. For example, it is very instructive/insightful to adjust the variable k in this compressive sensing blab to

    Currently, no. But this is our #1 priority. We're aiming for a simple embedding solution, e.g., 1) an html div with gist id attribute (plus loading a JavaScript file); and 2) a WordPress plugin. Stay tuned...

    We think so, too. Here's an example of a blab gallery based on modules from the popular Space Math @ NASA educational website: http://spacemath.github.io We would love to work with educators to create interactive blab gall

    Yes - STEM is a primary focus of Blabr. In fact, an initial application we had in mind was to convert interactive Excel spreadsheets from the Space Math @ NASA website ( http://spacemath.gsfc.nasa.gov ). We have several examples

    Thanks! By the way, if you click "Doc & Examples" (at bottom of blab), you'll see several of these dynamic demos under the "Demos" column. For the main demo on the home page, the editable table returns a vector

    Blabr currently supports pasting a string of values (space-separated, or comma+space-separated) into a table column. (Conversely, if you copy a table column to the clipboard, its values are stored in the clipboard as a comma+space-separated

    Developed a demo scripting tool ourselves. We plan to make it available for anyone to script their blab demos. Here's an example of a demo script: https://gist.github.com/mvclark/0a248098997a6f95635c

    Thanks very much! Please let us know if you have any questions or feedback. We have several new blab examples to share, too. Martin and Gary - Blabr developers

    Beautiful, fast interactive graphics. Would be good to have link to source on the page.

    Nice post. Another one I find useful is to define your own log function, e.g., function log(x) {console.log(x);}; You'd use log instead of console.log for debugging your code. Then, to turn off logging, you set function log(x) {}; or

    Setting n=12 for mass/springs shows some pretty nice dynamics in animated d3 graph. Loving the new in-code links, too.

    Yes, we want to add support for editing JavaScript directly in Puzlet Web Lab (it's particularly useful for copy/pasting snippets). We've found, however, that writing scientific computing code is much more succinct in Coffee
