After working for some time collaborating with open source/free software projects, I started to help newcomers to contribute and push the development further with good practices.
This post will try to itemize some important tips that can be used for software collaboration and personal projects, hopefully it'll help you to have a solid ground of good practices and advices for your contributions in a project. It contains information abut good code practices, a simple guide of helpful API design, code organization, comments, naming variables, development flow and self-criticism. Please enjoy, and any feedback (including critics) is much appreciated!

A long time ago I saw this in hackaday, after investigation over it on internet, I decided to get one from aliexpress ($9).
One question that I receive (from my friends, myself and people that install archlinux at 3am) appears every time. How to create a multiboot architecture inside a sdcard for the Raspberry Pi ?
After a boring day doing some unrelated stuff out of home, and with 1h free to do something before sleep and eating (heating my frozen lasagna), why not solving that secular question that follow me ?
Gtreamer is a great tool for everything that need to deal with video transmission, some things you can do with it:
After some time working with Qt3D, now Atelier project is one step closer to have a 3D viewer from the GCode and a realtime draw of printer work.

KDev-Embedded now have OpenOCD integration and a new interface to use avrdude in launcher.
With Arduino-Makefile, it's possible to use a makefile to perform compilation of Arduino projects. In the video one the the examples are used to shows how it is possible to use the new avrdude launcher to execute the upload process.

The GSoC plan to dominate the world of embedded system developments is near to have his first version !
Today one of the most important steps was performed, the first upload to a microController. The code was a blink compiled with a makefile and uploaded with the KDev-Embedded plugin to an AVR microController (Arduino Nano board).

The actual embedded system word depends on closed-source IDEs and libraries, with high monetary value and deprecated functionalities. Programmers that would like to use ARM based boards without paying for an IDE will have problems setting up such development ambient and synchronized toolkits.
The main idea of this project is to provide a plugin integrated with KDevelop to help the debugging and programming process of embedded systems like AVR, ARM and x86 based boards.
