Demystifying Datomic 'Two datoms in the same transaction conflict' errors
I love Datomic, absolutely love it. 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...

Reflecting on Rubyfuza 2015
Rubyfuza 2015 was amazing. 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. I have a lot of Ruby friends, that I only get to...
