correct. the bottleneck is not from the user to the access node (DSLAM, etc.) but from the DSLAM backhaul into the aggregation point. This is all still within the edge of the network. The core network is in a air-con data centre somewhere with 10GE connections. The connection from the DSLAM (DSL aggregation point) to the edge router is usually still ATM in most places and where the bottleneck usually occurs due to oversubscription, etc.
your complete movie archive in seconds is worthless if everyone in your street is doing it, the traffic never gets as far as the core before congestion occurs.
How secure is your current wallet with your personal details? It is quite interesting to note that we get overzealous when considering all things digital - yet our current methods of security and identification involve a photograph on laminated cards (in the case of drivers' licences).
With the advent of digital identification and such, we do need to take more care in the way in which we implement the technology - as due to the global nature of IT, certain security measures become easier to cirucumvent and automise.
However, we don't want to go overboard and have to remember the compramise we must make between ease of use and security.
A collection of vulnerabilities were posted by CERT yesterday for Internet Explorer. Having said this, I still do not understand how this particular article pertains to being "newsworthy". It is understandable if an issue which is deemed to have quite a large affect be posted - nothing is a substitution for using Bugtraq, et al mailing lists.
That is quite a good explanation... except that the article is about describing SPECIAL RELATIVITY which is a great deal harder to comprehend, let alone explain in a 5 minute presentation.
Your discussion, while being quite exceptional is on GENERAL RELATIVITY.

and on the twelfth day of Christmas, Linus left for me... an upgrade for linux-2.60.10-rc3
