Thanks For the ... Eight-Track, Uncle Alex
Uncle Alex writes "My niece just turned one year old and her parents have asked that, instead of the usual gifts, we each contribute something to a time capsule to be opened on her 17th birthday. Multiple members of my family want to contribute digital data — text, video, music files. They came to me (the closest thing to a geek our family has) wondering: what's the best way to save the data to ensure she'll actually be able to see it in 16 years? Software might be out of date, hardware may no longer be used... any suggestions?"
Of course, you could use paper ... but then you take the risk that people will still be able to read 17 years into the future!
16 years isn't such a long time, but just to be sure, put a netbook inside the capsule. Make sure it can run on external power alone, and remove the battery.
Get a plain writing book with acid-free paper and each write a personal story, message, commentary etc. Attach photos on stable stock paper together with personal items such as a slip of wallpaper or slither of wood etc. from her first bedroom, a dried flower from the garden, small items that conjure up the day/year she was born etc.
Store in a sealed box in a dry, safe, dust-free environment
Much more unique, personal and tactile. /Even geeks need to know when to stop

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.

Write it down.
I can still read a book a hundred years old, I can't read a C64-floppy twenty years old.
Open an account for her right now and place the username password combination in the time capsule. Once 17 she will then be able to ask slashdot how to read all the ancient media and have a geekish low account number when viewed fro 16 years into the future.
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.
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.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
I still have music CDs that I purchased in the 1970's that are still usable :)
1982 at the earliest.
But there is a difference between a pressed CD - which can last for a very long time - and a CDR which decays surprisingly quickly.

A pretty good trick since they weren't commercially available until late '82 :)
Do you realize that you're a looking at it with 20/20 hindsight? Yes, the 3.5" floppy did all right but loads of other media did not. I've used 8" floppies, 5 1/4" floppies, Iomega zipdrives, several sorts of tape drives, half a dozen different memory card standards... none of those were seen as fringe technologies at the time.
In other words: No, all technology will not be an arcane relic in 16 years but _many_ technologies will be. The trick is choosing the right one.
I would include a player for any media you have. I am still trying to cope with all my Mom's trays of slides...Oh, and make sure you include descriptions of the participants, I have a lot of old slides of people I presume are cousins, but I am not sure exactly who they are....
Or get the entire package, transform it into a single file (by whatever means necessary) and print the binary code of that file in 2D barcode, in plastic sheets.
It will last well over five thousand years and no matter the difficulty of reading it, it will always be at least possible.
If you expect your niece to become a vampire or somehow surpass the expiration date of plastic, you can pay a little to get the 2D barcoded plastic sheets engraved in metal sheets or tablets.
Follow those steps and your niece's time capsule might become the rosetta stone for an intelligent being aeons away.
Keep copies of all the software needed to play those video files *cough* vlc *cough*, and a means of running that program - maybe a whole OS in a raw hard disk image or something, so you can mount it in a virtual machine in 16 years. I'm sure some nerds will want to emulate x86 processors long after ARM has taken over.
Admit it. You post strawman arguments as AC so you get modded Insightful for refuting them, rather than Troll
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".
"For my clients, I always suggest the use of stone and / or clay tablets for all mission critical data archive projects, regardless of size or scope. Bablyonian and Greek models of data retention from as far back as 4,500 years ago are (in many cases) superior to the models we commonly use today, with much of the physical media having survived electrical storms, tornadoes, floods, fires, and wars on every scale imaginable with a data corruption rate of zero and without the benefit of a climate controlled room, dedicated security staff, or even a closet for media storage. Imagine the elegance of a 84'3/4 STROM (Stone Tablet Read Only Memory) machine hooked up to your Slackware Archive server for performing restorations, and the ST Binary Writer you have networked to your backup systems and kept physically over by the quarry... nice! The TCO for slab is far less than that of tape archives, considering you can store the media in a pile of mud and hose it down when you are ready for a restoration."

Why not tattoo the text on her body? Paper can get lost! Ok, use a mirror so that she can later on read the message without any difficulty.
What is writing? Encoding of information. Nothing else.
What is paper? An insufficiently dense medium for encoding huge volumes of data such as audio or video, even with a 75-square-inch block of QR Code on each page. Nothing else.
Or even better, do you have the ability to do things without each other. Staying in a room together without annoying each other for hours is fine, but marriage is being stuck in a room together for years. Sometimes you have to leave the room, be your own person, and then come back to the room.
I love /. tags!
What?
Most flash drive manufacturers state that their drives are not good for archival storage. They expect to lose data before 10 years have passed.
This is absolutely correct, no flash memory. Unlike hard drives (and tapes, for completeness), which store data as magnetic regions, flash memory stores actual electric charge. While the magnetic domains on an HDD are permanent (unless overwritten or degaussed), the small charge in each flash media bit will slowly leak away. The drive should still be usable, it just won't have your data on it anymore.
A portable hard drive might be the best solution, for its small size and relative permanence of data. Perhaps even an iPod, preloaded with music that it can play, pictures and video it can watch, and files that (assuming USB and the files system are still around) will also be available. One iPod with everyone's files could be a good split, and a great trip down memory lane. Just be sure to pack in a USB wall charging socket, just in case.
Write your representatives! Repeal the 2nd Law of Thermodynamics!
Most flash memory only quotes a retention time of a decade or so. Whether that is optimistic or pessimistic is not yet clear.

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 , or a working minidisc player?
What physical objects are new/cool/important/meaningful right now, that may not be later? Maybe throw a pair of her baby shoes in there... Grab something small off your dining room table or out of your front yard... Maybe the cell phone you just replaced... A couple ticket stubs to something that just opened... Toss in a cheap mp3 player (something that takes disposable batteries, like AA/AAA) loaded with some current songs on it...
In 17 years, when she opens it, you'll be able to say "Those shoes were on your feet 17 years ago. I talked on that cell phone 17 years ago. That's what we used to listen to music 17 years ago." And she'll be able to pick the things up, handle them, feel them, turn them on, see how they worked, compare them to whatever is current. Instead of just firing up a home-made version of I Love the '80s

If I were going to pick a random filesystem that will be readable in 15+ years for such a project, I'd probably put my bets on ISO9660, especially since this is a read-only storage situation.

What if USB ports disappear like PS/2, Centronics, and serial connections have disappeared?
This is a non-issue as you have described it. I just built a brand new computer 5 months ago. I was not interested in any of those items listed, yet it has a parallel port, a serial port, and two PS/2 ports. It's actually unfortunate that they don't make a RS-232 flash drive because the serial port is not going anywhere for a very long time. You might need to purchase a special card in the future to have it, but it is far too convenient and easy for use with industrial controls to ever die out.
I see the glass as full with a FoS of 2.
If you want to include digital files, the best option is to probably include the entire hardware/software stack to run it on. Get a netbook, and throw that in there. Kind of an expensive option, but definitely would ensure that the data could be read. I'm almost certain we'll still be using the same AC outlets in 17 years time. Or at worst, you'd need some kind of plug adapter.
