Who says engineers can't write? This is from the official IETF Internet-Draft entitled Interplanetary Internet (IPN): Architectural Definition

Desiderata of Interplanetary Internetworking


Go thoughtfully in the knowledge that all interplanetary communication derives from the modulation of radiated energy, and sometimes a planet will be between the source and the destination. Therefore rely not on end-to-end connectivity at any time, for the universe does not work that way.

Neither rely on ample bandwidth, for power is scarce out there and the bit error rates are high. Know too that signal strength drops off by the square of the distance, and there is a lot of distance.

Consider the preciousness of interplanetary communication links, and restrict access to them with all your heart. Protect also the confidentiality of application data or risk losing your customers.

Remember always that launch mass costs money. Think not, then, that you may require all the universe to adopt at once the newest technologies. Be backward compatible.

Never confuse patience with inaction. By waiting for acknowledgement to one message before sending the next, you squander tracking pass time that will never come to you again in this life. Send as much as you can, as early as you can, and meanwhile confidently await responses for as long as they may take to find their way to you.

Therefore be at peace with physics, and expect not to manage the network in closed control loops -- neither in the limiting of congestion nor in the negotiation of connection parameters nor even in on-demand access to transmission bands. Each node must make its own operating choices in its own understanding, for all the others are too far away to ask. Truly the solar system is a large place and each one of us is on his or her own. Deal with it.

Stating the Obvious gets an interesting new re-architecting. There's a really nice idea in there.

Hyperspace structures. Small (< 500K) mpeg's of a rotating hypercube and hypertorus.

Looks like booknotes is back from (short) hiatus. I found this link to punk rock and the two-way web. Nothing earth shattering, but interesting since I always think about the web in terms of deadheads.

Introduction to the Kaycee hoax. The metafilter thread where the debunking took place. Strange stuff. Metafilter itself was taken down yesterday (although maybe before, I hadn't looked in a few days) with a note that included references to this whole thing. Now it is back up. Not sure what any of this means, but it is the blog topic du jour.

Months ahead of schedule (well, ahead of the pushed back schedule) Apple begins shipping OSX preinstalled on all computers as of today.

Lots of good stuff here, like this explanation of why Godel's Theorem doesn't "prove" that AI is impossible.
