Understanding how code can be broken or lost

Code and its close cousin, configuration, take time and hard work. Code needs configuration to run, such as Raspberry Pi OS configuration, extra software, and necessary data files. Both need research and learning and to be designed, made, tested, and debugged.

Many bad situations can lead to the loss of code. These have happened to me a week before taking robots to a show after weeks of work, and I learned the hard way to take this quite seriously. So, what can happen to your code?

SD card data loss and corruption

SD card corruption is when the data on the SD card used to hold your code, Raspberry Pi OS, and anything you've prepared on it gets broken. Files become unreadable, or the card becomes unusable. The information on the SD card can be permanently lost.

If a Raspberry Pi unexpectedly loses power, the SD card can be damaged, causing data loss. A hot Pi can slowly bake an SD card, damaging it. Visual processing on a...
