Its rare that a hacker convention makes national news, but three MIT students caused a whole lot of controversy when they planned a presentation about security holes in Boston's subway system for DefCon in Las Vegas earlier this month. They were forced to cancel the talk at the last minute by a 10-day federal restraining order, requested by Boston's Massachusetts Bay Transit Authority (MBTA). On Tuesday, a judge denied motions by the MBTA to issue a preliminary injunction aimed at keeping the students quiet for a further five months. Now, in his most extensive interview to date, MIT subway hacker Zack Anderson talks with PM about what's wrong with the Charlie Card, what happened at DefCon, and what it's like to tango with the FBI and the MBTA.

Perspectives is a new approach to help clients securely identify Internet servers in order to avoid "man-in-the-middle" attacks. Perspectives is simple and cheap compared to existing approaches because it automatically builds a robust database of network identities using lightweight network probing by "network notaries" located in multiple vantage points across the Internet.
The extension provides two primary benefits:
   1. If you connect to a website with an untrusted (e.g.,self-signed certificate)*, Firefox will give you a very nasty security error and force you to manually install an exception. Perspectives can detect whether a self-signed certificate is valid, and automatically overrides the annoying security error page if it is safe to do so.
   2. It is possible that an attacker may trick one of the many Certificate Authorities trusted by Firefox into incorrectly issuing a certificate for a trusted website. Perspectives can also detect this attack and will warn you if things look suspicious.

Twenty-four contestants compete in an endurance/sleep deprivation contest in order to win a brand new Nissan Hardbody truck. The last person to remain standing with his or her hand on the truck wins. An absurd marketing gimmick at first glance, the contest proves to be much more...

The Ladies Home Journal from December 1900, which contained a fascinating article by John Elfreth Watkins, Jr. “What May Happen in the Next Hundred Years”.

Mr. Watkins wrote: “These prophecies will seem strange, almost impossible. Yet, they have come from the most learned and conservative minds in America. To the wisest and most careful men in our greatest institutions of science and learning I have gone, asking each in his turn to forecast for me what, in his opinion, will have been wrought in his own field of investigation before the dawn of 2001 - a century from now. These opinions I have carefully transcribed.”

I bought a cheap laser printer a couple years ago, and for a while, it worked perfectly. The printer, a Brother HL-2040, was fast, quiet, and produced sheet after sheet of top-quality prints—until one day last year, when it suddenly stopped working. I consulted the user manual and discovered that the printer thought its toner cartridge was empty. It refused to print a thing until I replaced the cartridge. But I'm a toner miser: For as long as I've been using laser printers, it's been my policy to switch to a new cartridge at the last possible moment, when my printouts get as faint as archival copies of the Declaration of Independence. But my printer's pages hadn't been fading at all. Did it really need new toner—or was my printer lying to me?
