Stephen Hawking is presenting a paper here in Dublin this week which appears to contradict his earlier theory (and bet) that information is ultimately destroyed in a black hole. I have supporting experimental evidence which I will present later. I only understand about half what I know about quantum physics, but I always found it interesting that energy, mass and information were related. Quantum mirroring is, as Einstein described, "spooky", but apparently real enough to use in practical encryption devices. The only thing I can glean from Hawking's abstract is that in the "simplified" math used in his earlier papers the event horizon exists from some frame of reference, but in the real space it never really catches up with itself. Pretty cool eh?
Experimental Evidence
Shortly after I posted last night's rant about Write Only Memory, my posting disappeared into the aether. Roller appears to have a timezone bug which couldn't handle the fact that it was after midnight here, but before midnight where the server lives. Roller couldn't handle articles being updated before they are created so the article disappeared. When time caught up with itself, it reappeared. This experimental evidence shows either that information* is indestructable or that bugs are very persistant. Somewhat related is the fact that several airline web pages offered flights on February 30th, 2004 but not on March 1st, 2004. Didn't we all go over this date related code a couple of years ago?
*The term "information" here is used very loosely. Any actual information in this article was immediately archived on
Signetics Write Only Memory The remainder of the article is simply a special case of the output of the infinitemonkeys.sh script:
#!/bin/sh
cat /dev/random | strings | grep "For being ignorant to whom it goes I writ at random, very doubtfully"
(don't try this on a thin client)

My second digital 8 camcorder stopped working last week. This just days before my daughter plans to take her first steps. I now have two camcorders which record but are unable to play. Write only memory. This focused my attention on a problem that has bothered me for a while. 
How do I maintain electronic images, movies and documents in a form that will be viewable when my daughter is old enough to enjoy them? The image (left) of this young political pundit stayed in one popular consumer format (Kodachrome slide) for 25 years. But in the last 10 years I've had to convert it from NTSC Betamax to Amiga IFF/ILBM to TIFF to JPEG, in order to view it on the latest consumer device. Government archivists and businesses face a similar problem on a much larger scale. Many important documents, images and videos are unknowingly archived in closed formats which depend on a particular vendor supply chain of licenses, software and hardware. Fortunately it is possible to convert between digital standards. For text documents we have multiplatform tools such as StarOffice and OpenOffice.org to convert between incompatible formats and an open (pkzip compressed XML) standard. For images we have gimp and an open-source multimedia library called gstreamer provides a good base for a universal multimedia translator.
Video is more difficult
But video presents unique problems. Transcoding is very time consuming and the numerous digital multimedia physical standards tend to have a short shelf life. Consumer digital 8 seems unlikely to survive as long as Betamax. Lossier small form factor standards seem poised to take the spotlight from MiniDV. Some are even predicting that DVDs will be replaced soon which would make them far more ephemeral than VHS or laserdisc. The interesting thing about this prediction is that it would require considerable investment in internet infrastructure, storage and servers. I wonder what company might benefit from that?
Once you've solved the physical media storage issue by keeping your videos in a fast, secure, persistant, magical "futurenet", you still have the issue of standards. Video is usually wrapped in a container such as Quicktime[tm] or Windows Media Framework[tm] and compressed with various coder decoder (codec) standards. These standards tend to be privately licensed and are seldom available on every platform. There is no obvious way to play certain Intel Indeo[tm] coded videos on recent Apple[tm] computers and it is difficult to find licensed Cinepak[tm] or Windows Media[tm] players for GNU/linux. Current DVD video standards require "analog hole" copy protection schemes such as Macrovision[tm] which is difficult to implement securly across the dozens of video cards that GNU/linux supports. And if the preliminary standard for next generation DVDs is accepted, all DVD-HD capable players will include the cost of a Microsoft[tm] codec license, extending the monopoly into yet another realm.
Pirates or Paranoia?
Digital multimedia allows lossless reproduction and provides the opportunity to bridge divergent international video standards NTSC, PAL, SECAM... but this accentuates the problem of piracy. So copy protection, royalties, taxes and laws were designed and region codes reintroduced an artificial technical barrier to cultural exchange. Such measures are understandable, but by focusing on large content suppliers they may be overlooking some consumer needs. When the owner of a DVD collection moves to a different region does he forfeit the right to view his DVDs? If I create multimedia content in a particular format, does the content still belong to me? Will I be able to legally transcode it without loss to the next format du jour? Will I be able to play it on the operating system and hardware of my choice or record it to VHS for the grandparents? I don't know. The current U.S. political climate appears to favor overturning the Betamax case court ruling which legalized VCRs. Technology companies such as Sun expressed concern over this legislation but few lawmakers understand the significant barriers to technical innovation such shortsighted laws are creating. Would JXTA be considered illegal peer to peer technology? What about the linux/unix `cp` and `mkisofs` commands? When my camcorders return from the repair shop I hope to capture a few favorite clips in an open standard such as theora just in case.
