I simply can’t imagine a world without it anymore. I can now relate to how the NoSQL crowd felt a decade ago when they were unshackled from relational databases, except this time I feel the technology has really...Mon, 29 May 2017 00:00:00 GMThttps://opensourcery.blog/2017/02/12/using-semantic-ui-react-with-re-frame/https://opensourcery.blog/2017/02/12/using-semantic-ui-react-with-re-frame/A practical guide to integrating Semantic UI React components into a ClojureScript re-frame application.

Any data eventually needs to be sorted for presentation. Most of the times we’re very lucky and we could lean on the implicit order of data returned from the database, or we can decorate that HTML table with DataTables and...Tue, 24 Jan 2017 00:00:00 GMThttps://opensourcery.blog/2017/01/05/the-jvm-is-not-that-heavy/https://opensourcery.blog/2017/01/05/the-jvm-is-not-that-heavy/ Mostly my opposition to Clojure is the JVM. That sh*t is heavy. This came up in the ZA Tech Slack team several weeks ago. While watching some Clojure talks over the holidays the speakers also noted this objection over and over again. I had a bit...Thu, 05 Jan 2017 00:00:00 GMThttps://opensourcery.blog/2016/05/27/smooth-client-side-routing-in-a-figwheel-only-project/https://opensourcery.blog/2016/05/27/smooth-client-side-routing-in-a-figwheel-only-project/One of the few things I missed when starting with re-frame was the excellent client-side routing setup you get with ember-cli, especially the development server part of that. After some digging I found this fantastic article, No-hashes bidirectional...Fri, 27 May 2016 00:00:00 GMThttps://opensourcery.blog/2015/11/29/error-reporting-and-building-hoverboards/https://opensourcery.blog/2015/11/29/error-reporting-and-building-hoverboards/October 21st came and went. We still don’t have hoverboards. But all is not lost! We can still embrace hoverboards, at least as a metaphor for having a frictionless software development lifecycle. The hoverboard metaphor came to be as I presented to...Sun, 29 Nov 2015 00:00:00 GMThttps://opensourcery.blog/2015/03/08/creating-an-ember-cli-addon/https://opensourcery.blog/2015/03/08/creating-an-ember-cli-addon/I’ve been using Ember.js for about 15 months at this stage, and I’ve absolutely loved it.

Just like all the other years, this one stood out on all levels. I love referring to Rubyfuza as a massive family reunion, except that everyone is excited to see each other.
