I work at JamKazam--<p>This is running the Linux real time kernel to help us achieve extremely low latency and I/O jitter. We've had to do a ton of fine tuning to get the latency as low as it is.<p>Our website is built on Ruby-on-Rails backed by Postgresql. We are using Resque for asynchronous jobs, and a Websocket/RabbitMQ solution to help with events in the browser and events else where in the backend.<p>Our JavaScript is a homegrown mess (jQuery and, ahem, 'business logic'). Having kept up with the latest web tech mostly through HN, I'd take the React/Flux plunge if starting from scratch; I'm still looking for an excuse to start using them anyway, even if just for part of the site!<p>Anyway, we are very excited to be starting the KickStarter for the JamBlaster, because it's your best way to get the latency low enough to have a really good jam session.<p>/me fingers crossed
Link to previous discussion on HN, looks like they've come a long way! <a href="https://news.ycombinator.com/item?id=8324567" rel="nofollow">https://news.ycombinator.com/item?id=8324567</a>
