Planet Ubuntu -
1 days and 8 hours ago
img class=face src=http://planet.ubuntu.com/heads/emmajane.png alt= pAt the a
href=http://onlinux.ca/Ontario Linux Fest/a I had the wonderful opportunity of having lunch with a
href=http://www.samba.org/~jra/Jeremy/a. It was after his keynote talk. I had lots of questions,
which he very generously tolerated as we ate our beet sandwhiches. We chatted about the future of
data and ownership and various things and he recommended Van Jacobson's Google Tech Talk: a
href=http://video.google.com/videoplay?docid=-6972678839686672840amp;q=engeduThe Future of the
Internet/a. The video is just over an hour long and I haven't taken the chance to watch until
today. (I've been recovering from the flu and I decided this video was like watching Q in his lab
coming up with the gadgets. There were fewer explosions, but I probably learned more.)/p pHere are
a few of my favourite points (hopefully they're enough to entice you to spend an hour watching, or
at least listening to, this talk)... The talk starts out with a great history of communications
(including why we started with four-digit phone numbers)... and then it got more interesting... /p
ul liPeople don't want to have conversations. They just want their Web pages. They hand in a URL
and they want to get something back. That's not a conversation. It's the computer equivalent of,
quot;does anybody have the time?quot;Â /li liOur current model doesn't stop the spam.
The content is garbage, but it came from my mail server, so it must be a good conversation. Things
are currently blind to the data./li liChange your point of view to focus on the data. Not where the
data lives, because it doesn't have to live anywhere. Data is named. When you want a chunk of data,
you present its name to the network, and it doesn't matter what kind of networking technology
you've got, use them all, it's asking does anybody know where we are? Pass this data out to the
network and hope that somebody can give you a reply. /li liiAnd then he read my mind because what
he was describing /isounds likei caching... but it's not./i The effect is very much the same. In
caching you say, oh the data lives there, but I've got a copy of it here. In my model the data
doesn't live anywhere. Whereever it is, that's great. I can authenticate it and I know whether or
not I can trust it.... I'm not moving it from it's one true location to somewhere else...it doesn't
have one true location./li liIntegrity and trust are properties of the data, not of the way that
you obtain it./li liSo this is, by contrast to the Microsoft Authenticode model, where you download
this update from Microsoft, then there's a little window that comes up and says, quot;Do you trust
Microsoft?quot; And the answer is quot;NO!quot; and I kept clicking quot;noquot; and my machine
never got updated. [iThe audience and I both laughed at this./i] I don't! Their model is quot;Do
you trust their delivery mechanism?quot; They're basically asserting loading this update won't
cause financial harm to Microsoft. Great, but that's not what I want. I want my machine to work. I
want to know what you're going to do to my machine. I want to know something about the data and the
operations you're going to take, but they can't tell me that. So I want properties of the data
where I don't have to trust remote agents, that the data itself lets me figure out what it means
and who sent it and how it's connected to the world./li /ul pThis last point reminds me of a
href=http://www.lauracowen.co.uk/blog/Laura/a's recent request to have a
href=http://www.lauracowen.co.uk/blog/2008/11/30/updating-nvidia-graphics-drivers-with-ubuntu-kernel-updates/system
updates a little bit more system-aware/a. (It also reminds me of the first time a a
href=http://episteme.ca/friend of mine/a told me to download some form of a
href=http://www.openbsd.org/BSD/a from the Intarwebs and I clicked quot;surequot; because it had
blowfish and then promptly FREAKEDOUT the download screen seemed to be taking over my computer and
further more I was supposed to just trust a whole operating system that just existed somewhere on
the internet?! That's CRAZYTALK.) So go watch the video and then go read Laura's blog post. Do I
have any solutions to entice you back here? Um, nope! Just some brain fodder. So away you go! It's
not as exciting as the new a href=http://www.007.com/Bond movie/a, but it is something you can
enjoy from the comfort of your own home./p
