Whether you’re a seasoned git user, thinking of migrating to veracity for bug tracking, or are just generally interested in the concept of centralized or distributed version control be sure to check out Eric Sink’s Version Control by Example – available online for free, nice!
A version control system is a piece of software that helps the developers on a software team work together and also archives a complete history of their work.
There are three basic goals of a version control system (VCS):
We want people to be able to work simultaneously, not serially.
Think of your team as a multi-threaded piece of software with each developer running in his own thread. The key to high performance in a multi-threaded system is to maximize concurrency. Our goal is to never have a thread which is blocked on some other thread.
When people are working at the same time, we want their changes to not conflict with each other.
Multi-threaded programming requires great care on the part of the developer and special features such as critical sections, locks, and a test-and-set instruction on the CPU. Without these kinds of things, the threads would overwrite each other’s data. A multi-threaded software team needs things too, so that developers can work without messing each other up. That is what the version control system provides.
We want to archive every version of everything that has ever existed — ever.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
