Elasticsearch and doubling down on "open"
Philipp Krenn joined the show to talk with us about Elasticsearch, the problem it solves, where it came from, and where it’s at today. We discussed the query language, what it can be compared to, whether or not it’s a database replacement or a database complement, Elasticsearch vs Elastic the company.
We also talked about the details behind Elastic’s plan of “doubling down on open” to open up X-Pack, which is open code paid add-on features to Elasticsearch. We discussed the implications of this on their business model, and what changes will take place at the code and license level on GitHub.

Winamp2 JS
Jordan Eldredge joined the show to talk with us about Winamp2-js — a reimplementation of Winamp 2.9 in HTML5 and Javascript. For many of our listeners, talking about Winamp may bring to mind some extreme nostalgia about the internet of the past … and it’s certainly that way for Jerod and I. Jordan started this project in 2014 and it’s what ultimately got the attention of some folks at Facebook, where he now works on Nuclide.
We shared stories about Winamp back in the day, actually listening to music as an mp3, the technical hurdles and learning Jordan has experienced, skinning it, playlists, making it a frontend for Spotify – which is so ironic to actually say. Also, Jerod has been hacking it via livestream on Twitch to add it as an alternate audio player on Changelog.com.
