SSL's dirty little secret

SSL helps but is not a panacea. In a corporate environment, it is possible for IT to monitor SSL-encrypted traffic using so-called Data Loss Prevention applications, such as Bluecoat's ProxySG SSL-interceptor:

This can be prevented using Firefox's Adblock Plus add-on

This describes how to use Firefox's "Adblock Plus" add-on to prevent other Web sites from accessing Facebook:

How to use Adblock Plus to block other Web sites' access to Facebook

You can use Firefox's Adblock Plus add-on (https://addons.mozilla.org/en-US/firefox/addon/1865) to prevent any other Web site from talking to Facebook when you visit that site. Just install Adblock Plus and then add the following filters:

||facebook.com/*$domain=~facebook.com|~facebook.net|~fbcdn.com|~fbcdn.net

||facebook.net/*$domain=~facebook.com|~facebook.net|~fbcdn.com|~fbcdn.net

||fbcdn.com/*$domain=~facebook.com|~facebook.net|~fbcdn.com|~fbcdn.net

||fbcdn.net/*$domain=~facebook.com|~facebook.net|~fbcdn.com|~fbcdn.net

The above filters tell Firefox never to allow any site other than Facebook's four sites (facebook.com, facebook.net, fbcdn.com, and fbcdn.net) to access Facebook. Thus, Facebook continues to work perfectly, but other sites don't get to talk to Facebook at all.

Sounds like an NFS-mounted swap partition

Jeez, back in 1987 I had a Sun 3 with no local disk, so it had to page over (10 Mb/s) Ethernet. Isn't this substantially the same thing (but with faster networking)? Try telling the server owner that he has to trade nanosecond-scale RAM latency for millisecond-scale LAN latency.

Reminds me of a funny Onion news video ...

This is real code reuse ...

#!/bin/sh

cat "$1" | grep '^cost:' | cut -f3 -d" " | tr A-Z a-z

Very small well-defined components that do one thing very well running in an environment that makes it easy to glue them together.

Shouting fire in a crowded theatre

Steve Roper wrote: "[...] society as a whole MUST impose limits. Perhaps the best known example of this is the statement 'The right of free speech does not carry with it the right to shout 'Fire!' in a crowded theatre.'"

Unless, of course, there's a fire. This may be such a case.

HD-DVD movies are already available for download via BitTorrent

Indeed. Taking it one step further, only one person needs to decode the discs and upload the _unencrypted_ HD-DVD via BitTorrent. Such decrypted HD-DVDs already available via BitTorrent:

Of course, not everyone has the time or disk space to download a 20 GB movie (HD-DVD movies are much bigger than plain old DVD movies), but 10 years ago downloading a 4.5 GB DVD would have been an equal hassle.
