The wargames offered by the OverTheWire community can help you to learn and practice security concepts in the form of funfilled games. To find out more about a certain wargame, just visit its page linked above. If you have a problem, a question or a suggestion, you can join irc.overthewire.org on port 6697 using an SSL-enabled IRC client, or irc.overthewire.org on port 6667 using a regular IRC client.
This is like a text adventure, except its unix/cryptography/C.
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.
