If you're a heavy user of OpenSCAD then you'll eventually get to the point where you have folders full of .scad files, with no idea what they are. Here's how to make a thumbnailer that will automatically generate a preview image that will display .scad files in Nautilus.
Over the past 6 months I've been working on developing an open source robotic sailboat called Pilothouse.
The goal of Pilothouse is to make an open source robotic sailboat that can autonomously navigate and sail itself long distances, and to prove that this can be done using the latest web technology: Node.js.
Pilothouse has a number of awesome features, including:
Robotic sailing, with 100% all natural renewable energy.
WiFi based monitoring with remote GUI.
Full Ubuntu Linux environment onboard.
Advanced sensors, including the latest GPS and MEMS.
Potential for expansion into a fully autonomous ocean going science vessel.
Sequelieze is a great tool for database ORM mapping in Node.js, but it can have a pretty steep learning curve. In this post we go over some useful patterns related to subqueries in SQL, and their Sequelize equivelents.
