This looks neat! I keep a similar list for conferences focused on web operations. All the data is in a YAML file, and it's four lines of ruby (excluding the template) to generate the site.
We published a huge list of conferences at http://techconfs.co. List has not been updated yet for 2016 dates, but maybe you can find some new conferences of interest on the site.
