Though ya security is important, can probably use something analogous to the best in computer security and implement in the real world. Capability based security is analogous to keys, and ring security is similar to nested rooms. > North pole is ice pack -- it all melts and drops your stuff into the sea. > Hmmm, by polar I meant in the vicinity of the poles, perhaps Arctic would be a better descriptor. Even in southern Ontario we have a slice of subarctic climate at the northern tip of lake superior. Though there are plenty of accessible glaciers and mountainous caves on the west coast. We could have something on the Arctic islands as well of course, though it would only be accessible during the summer months. There is a military base Alert on Ellesmere island, but it would likely be prohibitively expensive to use them as transport.

It however also would only be accessible (except by satellite) during the summer months. > On 10/20/2012 8:43 PM, Logan Streondj wrote: > >> >> On Sat, Oct 20, 2012 at 12:41 AM, Ben Goertzel <[email protected] >> <mailto:[email protected]>> wrote: >> >> Perhaps you should etch your blog on a metal disk, like the Rosetta Disk >> ;-) >> >> http://rosettaproject.org/**disk/concept/<http://rosettaproject.org/disk/concept/> >> >> ... ben g >> >> Yes I was at least partially inspired by their project. >> However the kind of resolution they have is not available off-the-shelf. >> It's somewhat unfortunate that they don't have a forum on their site, >> and so it's not possible for people that are interested in archival and >> longevity to >> get together there and suggest more "every-day" solutions. >> >> quote >> And cast some copies into space, so that it will survive even the >> potential end of >> the planet !!! >> >> quote ben g from >> >> Well that isn't currently affordable either, >> and copies in space aren't very accessible for reference. >> Also there is the danger of burning up at re-entry. >> >> A remote storage location I was considering was the poles, >> they are very cold which is good for archival purposes, >> and also are much more accessible. >> >> It's one of the reasons I'm interested in living on a boat. >> Maybe can have some analog of Iron Mountain in Canada, >> perhaps "cold mountain" and could even do those.. >> cryo-preservation of people, with lower cost. >> >> On Sat, Oct 20, 2012 at 7:28 PM, Eugene Surowitz <[email protected] >> <mailto:[email protected]>> wrote: >> >> A car frame or a statue are examples of bulk usage >> and isn't actually what I was talking about. >> >> A car body on the other hand is a different kettle of fish >> as is the use for the pages of the notebook in question. >> Cars have a short half-life so the problem is rarely >> noticeable particularly with the frame. >> >> Those are thin shells.
