We must fight spam for the same reason we fight crime: not because we are naive enough to believe that we will ever stamp it out, but because we do not want the kind of world that results when no one stands against crime.  - Geoffrey Welsh

Yet another amazing new digital technology. Who would have ever even thought it possible? A box that magically transmits your voice using radio waves, and then, through a system of networked repeaters, it can be heard on another box at a distant location. This is absolutely the most amazing new thing I have seen in decades. We owe a debt of gratitude to the news media, which does an excellent job of keeping us informed about all this new technology. Just think how hard the previous generations had it. For example, prior to 1972 there were no Bic lighters. I am old enough to remember those times - sitting around freezing in the dark, eating uncooked food. We really have come a long way.

Everything I consider to be "phone system". When I say "out", I mean "not functioning". If I can't get a dialtone, it really doesn't matter what parts are broken, does it? > So your post to c.d.t. came in through FidoNet over s/w Ham Radio :-) ? No, it was posted via my packet radio gateway, w1ac.ampr.org, and passed onto the Internet at a ham radio station in Columbia Falls, Montana. I've never used FidoNet, but IIRC, FidoNet depends on modem links for communication, so it wouldn't have worked anyway. > Anyway, kudos for getting through, however you did it!

Subject: Crack in Internet's foundation of trust allows HTTPS session hijacking Message-ID: <p0624081bcc79aaa17de1@[]> Crack in Internet's foundation of trust allows HTTPS session hijacking Attack dubbed CRIME breaks crypto used to prevent snooping of sensitive data. by Dan Goodin Ars Technica Sept 13 2012 A screen shot from a video showing CRIME decrypting the contents of an encrypted cookie used to authenticate a dropbox.com user account. Researchers have identified a security weakness that allows them to hijack web browser sessions even when they're protected by the HTTPS encryption that banks and e-commerce sites use to prevent snooping on sensitive transactions. The technique exploits web sessions protected by the Secure Sockets Layer and Transport Layer Security protocols when they use one of two data-compression schemes designed to reduce network congestion or the time it takes for webpages to load. Short for Compression Ratio Info-leak Made Easy, CRIME works only when both the browser and server support TLS compression or SPDY, an open networking protocol used by both Google and Twitter. Microsoft's Internet Explorer, Google's Chrome and Mozilla's Firefox browsers are all believed to be immune to the attack, but at time of writing smartphone browsers and a myriad of other applications that rely on TLS are believed to remain vulnerable. CRIME is the latest black eye for the widely used encryption protocols, which act as the Internet's foundation of trust by encrypting traffic that flows over open networks and cryptographically proving websites such as Gmail are really operated by Google rather than criminal hackers or state-sponsored spies. The specter of a new attack that could subvert one of the only widely available protections preventing the interception of sensitive e-mails and web transactions, follows revelations that both Iran and China have actively worked to defeat it so they could spy on its citizens. ... http://arstechnica.com/security/2012/09/crime-hijacks-https-sessions/
