    Physical objects should go into the capsule, not data. The reason we do that is because it's difficult to keep archived objects pristine and from getting lost. With data, you can store it in multiple places and always retrieve a bit for bit exact copy. Not so with physical objects.

    Well, think what was around 16 years ago (1993) and project forward:

    The compact disc had been invented for a little over 13 years and was still going strong (and would do until five-ten years after that).

    Thinkpads were available with CD etc. (although we're talking 486's here because the Pentium was JUST coming out)

    So if you dug up an old 486 with some CD's now, how hard would it be to get running? How hard if your particular units didn't work? Not very.

    Now project 16 years into the future - buy yourself some *new* reliable technology (CD was in its infancy as a computer format in 1993). Make it as standard and popular as possible. Throw in a device that's still likely to be passed around on second-hand websites like eBay just in case. Hell, I can still buy ZX Spectrums for little more than a few dollars, and that was 25 years ago. Hedge your bets... use a Blu-Ray AND DVD for everything you want to put in there. Throw in some Windows / Linux / Open Source / freeware to read the data (don't do a BBC Domesday project and have to decode the software as well as find the hardware).

    If you wanna be ultra-sure... throw in a Gumstix or something small and capable of playing the media (you could use USB memory in this case, or CompactFlash or similar). Hardware easily survives 16 years if you look after it or don't touch it. The data media may not (especially writable media) so project it forward with each transition of your own personal data.

    And most importantly - backup, backup, backup. Include *two* of each device, and two copies of the data in two different media, on two seperate discs/flashs and keep a copy on your home machine to "upgrade" to the next new format.

      First, when I think about what I was doing in 1993 and you point out it was 16 years ago, you just make me feel old.

      Thanks a lot.

      Second, I wouldn't project the pace things changed in the last 16 years to the pace they're going to change in the next 16. Half of that time was still before the massive explosion in computer usage. 16 years ago computers were a "nerd" interest. Some of us had Internet, and some colleges had it available to students, but most people were using BBS's or other dial-up destination services. Computers were uncommon.

      Today, new technologies come and go in the matter of years. Technology uptake is multiples faster than it was 16 years ago. Even basic things like interface types are starting to vanish. Firewire? SCSI? Parallel ports? Floppy drives? CDs are starting to fade, less than ten years after the use of them for recordable storage became practical. Even DVD recording is starting to fade because media has gotten too big for DVDs.

      I wouldn't assume for a moment that any hardware or media today will work on a computer 16 years from now. USB 3/4/5 may have some backwards compatibility, but wireless connectivity and higher bandwidth standards will show up, and there will be a point that going 3-4 revisions back on a standard just won't happen. Your USB flash drive won't work anymore. Bandwidth into homes and dropping flash prices will almost certainly eliminate optical storage by that time. They're already too small for backups, and useless for most people for music playback. My video camera *today* can shoot video big enough to fill a dual layer DVD in 15 minutes.

      IMO, putting digital content in a time capsule is a waste of time. The odds are SO low that it'll be readable in 16 years without someone tracking down very old hardware to use, I think they're better off putting physical things that mean something in there.

    Recently it was mentioned on a documentary I've seen: 10,000 years of evolution, and the best thing to conserve information we came up with was stone tablets.

    It's unfortunately true. The more sophisticated our means of storage are, the more brittle and frail they are. Essentially, you would have to bury not only the medium but also the means to play them back. The tricky part is finding out "where to stop".

    "Thanks for the 8track" was a quite good tagline for this problem. 20 years ago, an 8track would have been the thing to store information on. Today, you would have a hard time finding a player. And the problem gets worse with every year. Magnetic tapes, VHS or Beta, dominated the video market for over two decades. DVD didn't dominate for one. BluRay is probably going to be replaced before long. The time between generations of players is shrinking quickly. Soon we'll see, if you're not an early adopter, you're already lagging a generation behind.

    The most sensible way, and a worthy geek project too, would be to create a playback device made entirly from standard off the shelf parts that you may sensibly assume to be still available in a few decades, put the packing list along with the content you want to preserve into the box and make sure you also store your content in a way that survives the test of time.

    You only have to bridge about two decades. It would be a very interesting project to try something like that with the goal to make information last millenia.

    • 20 years ago, an 8track would have been the thing to store information on.

      20 years ago CDs were almost 10 years old, and 8-track was already "20 years ago, and you'd have a hard time finding a player".

    • 10,000 years of evolution, and the best thing to conserve information we came up with was stone tablets.

      It's unfortunately true.

      It is really, really not true. Have you ever stopped to consider

      1. survival rate -- i.e. how many clay/stone tablets have not survived four millennia; and
      2. how many clay tablets would have survived if kept under normal operating conditions -- i.e. not being fired when an invading army set fire to your city?

      Now stone, I grant you, gets past the second of these conditions better than clay. However, it fails the first condition even more spectacularly than clay does, since stone tends to get destructively recycled

    The files are a little tougher, but it's hard to imagine .jpg, .mpg, and .mp3 ever not being supported. Those are standards which are also more likely to be updated than ditched, I think.

    The most sensible thing would be digital files, with a maintenance schedule -- migrate to a new medium every so often.

    However if the requirement absolutely requires that a physical medium is locked up or buried for 17 years, then I'd go for analogue media with tangible encodings:

    • For text and images, paper and ink (for longer periods, carve stone or etch metal!)
    • For audio, get some vinyl pressed
    • For video, 8mm film

    It may not be easy to play the vinyl or the 8mm film in 17 years -- but it will be possible, and decay is less likely to be catastrophic.

    Data doesn't go into time capsules. There's absolutely no reason why you couldn't share that text, video, or music with her at any point over the next 17 years. And she'll likely be exposed to it anyway... Music will be playing on the radio, books will be available, folks will share family pictures and videos...

    It might make sense to include a photograph with a note on the back, or a couple-page letter to her... But you don't just stuff the capsule full of digital data. That stuff would be better archived on a live computer and updated over the next few years.

    What you put into a time capsule are physical objects. Think back to 17 years ago... What would be more fun to stumble across - an mp3 of I'm Too Sexy [youtube.com] , or a working minidisc [wikipedia.org] player?

The next is to ensure that you have multiple packs of Silica Desicent to handle any extra moisture (corrosion reduction). In regards to the container itself, it needs to be waterproof and possibly air tight but not gas proof as you'll eventually need to purge all Oxygen from the container using Inert Dry Nitrogen. Then simply don't open it until the designated time (birthday gift is a great idea). Another way of introducing Dry Nitrogen into the case is the use of Liquid Nitrogen and allowing it to evaporate. The advantage is it will drive all of the oxygen out of the case and ensure a very slight overpressure, which helps keep moisture from entering.
