Announcing Laser Cutter and MakeABox.IO

LaserCutter & MakeABox.io — its a ruby gem and a website for making PDF designs of laser-cut boxes, which fit/snap in together at all edges using tabs that go in and out. The output of the library is a PDF document. Typically next step would import that PDF into Adobe Illustrator for additions and touch ups, and then sent off to a laser cutter for the actual, well, cutting.

BackSeat Driver: Autonomous Vehicle Library for Arduino

Back Seat Driver is a library for programming autonomous (or not) Arduino based robots. This library provides a convenient non-blocking command API to programmatically drive an autonomous vehicle. Current implementation is aimed at a 2-wheeled robot, with the two Servo motors setup opposite each other. Therefore to move the robot forward (or backward), two Servos need to rotate in the opposite direction (this is certainly true in the current version of the library, but may be more flexible in the future if need arises).

Twelve Step Program For Scaling Web Applications On PostgreSQL

In this exciting and informative talk, presented at PgConf Silicon Valley 2015, Konstantin cut through the theory to deliver a clear set of practical solutions for scaling applications atop PostgreSQL, eventually supporting millions of active users, tens of thousands concurrently, and with the application stack that responds to requests with a 100ms average. He will share how his team solved one of the biggest challenges they faced: effectively storing and retrieving over 3B rows of 'saves' (a Wanelo equivalent of Instagram’s likes or Pinterest’s pins), all in PostgreSQL, with highly concurrent random access.
