Cache, Aha, Saviour of the Universe

There is no pain greater than hearing a sudden crunching sound and watching the screen on your laptop lurch into a permanent blackness. It is a horror that we all experience and never get over. Which is why some people, who are probably at this very moment wearing glasses and a novelty t-shirt that features a coding pun, initiated World Backup Day, which occurs on March 31st each year. All of us non-Luddites are encouraged to save and store our vital data and backup our bits. Then it won’t matter how many Sunny D’s you dump on your hard drive - you can still access that video of the cow doing a poo on that man trying to milk it.
