Turn your Raspberry Pi into a kiosk playing looping videos

An acquaintance needed a video kiosk that plays looping videos for an exposition booth. Since I have a bunch of Raspberry Pis lying around, I figured that it would be the perfect use case for using one of them.

Let's assume we start from scratch, with a unflashed, brand new SD card and your Raspberry Pi.

Installing the OS

Install a version of Raspbian that includes the desktop. You can head over to : https://www.raspberrypi.org/downloads/raspbian/ and follow the instructions.

Once the image is downloaded, you can burn it to your SD card with tools like Etcher (https://www.balena.io/etcher/)

This is my technical interview cheat sheet. Feel free to fork it or do whatever you want with it. PLEASE let me know if there are any errors or if anything crucial is missing. I will add more links soon.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

	A Minimal Capture Program

	This program opens an audio interface for capture, configures it for
	stereo, 16 bit, 44.1kHz, interleaved conventional read/write
	access. Then its reads a chunk of random data from it, and exits. It
	isn't meant to be a real program.

	(Easy): Sum-the-Digits, Part II (http://www.reddit.com/r/dailyprogrammer/comments/1fnutb/06413_challenge_128_easy_sumthedigits_part_ii/)
	------------------------------------------------------------------------------------------------------------------------------------------

	Given a well-formed (non-empty, fully valid) string of digits, let the integer N be the sum of digits. Then, given this integer N, turn it into a string of digits. Repeat this process until you only have one digit left. Simple, clean, and easy: focus on writing this as cleanly as possible in your preferred programming language.
