These days, there's no dearth of great resources for learning to code . Here's another great one, a 21-chapter book posted online and chock full of JavaScript training.
Once you have a 3D printer, making copies of objects like a futuristic Xerox machine is the name of the game. There are, of course, 3D scanners available for hundreds of dollars, but [Joshua] wanted something a bit cheaper. He built his own 3D scanner for exactly $2.73 in parts, salvaging the rest from the parts bin at his local hackerspace.
[Josh]‘s scanner is pretty much just a lazy suzan (that’s where he spent the money), with a stepper motor drive. A beam of laser light shines on whatever object is placed on the lazy suzan, and a USB … Read the rest

Infrastructure-as-a-service (IaaS) server and cloud hosting provider Linode declared its library of guides and tutorials "open source" this week, inviting the community to peruse and contribute to the documentation for deploying cloud applications on the company's open source-friendly platform.
The guides and tutorials, which the company calls the Linode Library, has been around for five years. But they're now available in full on GitHub, where anyone can access and modify them, as well as add new content.
Crate Data is a shared-nothing, fully searchable, document-oriented cluster data store. It is also 100 % open source. They built it so developers with a data intensive back-end won’t need to “glue” several technologies together to store documents, blobs and support real-time search. They also wanted to help developers avoid the manual work associated with [...]

A nippy microkernel mathematically proven to be bug free*, and used to protect drones from hacking, will be released as open source tomorrow.
The formal-methods-based secure embedded L4 (seL4) microkernel was developed by Australian boffins at National ICT Australia (NICTA) and was part of the US Defense Advanced Research Projects Agency's High-Assurance Cyber Military Systems program hatched in 2012 to stop hackers knocking unmanned birds out of the sky.
Flappy Bird has been ported to just about every system imaginable, including but not limited to the Apple II, Commodores, pretty much every version of the Atari, and serves as a really great demonstration of the TI-99′s graphics capabilities. Porting is one thing, but having a computer automate Flappy Bird is another thing entirely. [Ankur], [Sai], and [Ackerly] in [Dr. Bruce Land]‘s advanced microcontroller design class at Cornell have done just that. They’re playing Flappy Bird with a camera, FPGA, and a penny wired up to a GPIO pin to guide the little 8-bit-bird through Mario pipes.
The setup … Read the rest
