Computers have made it easier and easier for people to create incredible amounts of data -- passing the zettabyte barrier in 2010. The growth of data is actually surpassing our ability to store it, and it's a bit concerning that our ability to store digital information for long periods of time isn't too reliable (just try to access stuff on a 5.25" floppy). Here are just a few interesting links on preserving information for thousands of years.
- Digitally-stored information about nuclear waste needs to be accessible many thousands of years from now. Engraving the info on sapphire discs with platinum is just one proposed solution that could work for future archaeologists -- but in what language should it be written? [url]
- If you thought your burned CDs/DVDs lasted forever, think again. But if you still want to store your data on plastic discs, there's a company (Millenniata) that sells an optical disc engraving technology for writing CDs/DVDs that work with standard CD/DVD readers -- and that claims to last for about 1,000 years (or at least hundreds of years).

- Neanderthals were making cave paintings over 40,800 years ago in Spain. How much of our art will survive the next 40,000 years? [url]
