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:


For details on how it's done, see:

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:





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.

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

Latest AACS crack 'beyond revocation'

HD-DVD movies are already available for download via BitTorrent

John Ridley wrote: "[...] it's not necessary for everyone who wants to crack AACS to have one of these hacked drives. All that's necessary is for someone, somewhere in the world, to have a drive, then use that drive to extract the key, then publish the key. Boom, everyone can decode the discs."

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.
