Over tijd en het netwerk

Tijdens het Webstock-congres in Nieuw-Zeeland gaf Jeremy Keith een interessante presentatie over tijd in verleden, heden en toekomst, standaarden, URL's, linkrot, flash crash en HTML.
Wat parafraseringen en citaten.

Tijdverkoopster
Zo vertelt hij over Ruth Belville, die de tijd verkocht. Ze woonde in Londen en reisde iedere dag naar Greenwich om haar horloge gelijk te zetten op de klok die de Greenwich Mean Time aangaf. Daarna ging ze langs bij haar klanten zodat die hun klok gelijk konden zetten. Pas zo'n zeventig jaar geleden, rond 1940, is Belville hier pas in mee gestopt!

Standaarden
In the world of atoms, in the world of physical things, the shipping container. It’s the most important standard for physically moving stuff around the planet. It is a standard. It’s ISO 6346, the dimensions of the shipping container. There’s about seventeen million of these in the world, and about ten thousand go missing every year; they just fall off a ship.
Algoritmes en de flash crash (speciaal voor Chido)
The bots are trading. And we don’t know what they’re doing. We built them, but what they then do is beyond our comprehension. They do things we don’t understand. Like on this particular day, May 6th 2010. This was the flash crash. The Stock Market crashed a thousand pounds in minutes. At the time, they didn’t know why this happened. They still don’t know why this happened. It was algorithms; algorithms that we build, but we don’t control.
At least these algorithms were made by human beings. Once we start designing algorithms for building algorithms, we’re totally screwed.
The internet doesn't forget
How often have you heard the phrase, ‘the internet never forgets’ or ‘Google never forgets’, ‘Facebook never forgets’? These phrases are thrown around as truisms, and we nod our heads, oh yeah, yeah, the internet never forgets. Just like the Eskimos have fifty words for snow and everyone at the time of Columbus thought that the world was flat. These things sound logical and reasonable, but they’re all completely false.
Where do you get this data that the internet never forgets? If you actually look at the data, the internet forgets incredibly quickly.
Long bet en URI's
Een van de projecten van de Long Now-foundation zijn de zogenaamde Long Bets, the arena for accountable predictions. Keith heeft daar vorig jaar de volgende weddenschap afgesloten:
“The original URL for this prediction (www.longbets.org/601) will no longer be available in eleven years.”
Waar hij aan toevoegt:
"Cool URIs don't change" wrote Tim Berners-Lee in 01999, but link rot is the entropy of the web. The probability of a web document surviving in its original location decreases greatly over time. I suspect that even a relatively short time period (eleven years) is too long for a resource to survive.
I would love to be proven wrong.
Nou ja, je moet het zelf maar even bekijken, lezen of  beluisteren. Ik vond het wel de moeite waard.
