Fractal fun with HTML5 and TypeScript

MbCanvas is a fun project that I did in 2015: a simple Mandelbrot Set viewer written in Typescript and using the HTML5 Canvas. I did the project to learn more about Typescript and the HTML5 Canvas and I must say, Typescript very nice -- so much easier to read and write than plain old JavaScript, at least for me.

Here's an example image from the viewer.

The project is fairly easy to build if you've got Node and NPM installed, or you can play around with it here: mbcanvas - Mandelbrot viewer in TypeScript


Usergrid-Vagrant updated for Usergrid 2

GitHub logo

If you're interested in trying the not-yet-released Apache Usergrid 2 you might want to checkout my Usergrid-Vagrant project on GitHub. I just updated the project to support Usergrid 2, using the latest code from the Usergrid "release" brach. The big changes were switching to OpenJDK 8 and adding ElasticSearch. I also rewrote the scripts to use plain old Bash instead of Groovy.

If you want the old Usergrid 1 Vagrant-file then checkout the "1.x" branch.
