Home-Built Turing Machine 123

stronghawk writes "The creator of the Nickel-O-Matic is back at it and has now built a Turing Machine from a Parallax Propeller chip-based controller, motors, a dry-erase marker and a non-infinite supply of shiny 35mm leader film. From his FAQ: 'While thinking about Turing machines I found that no one had ever actually built one, at least not one that looked like Turing's original concept (if someone does know of one, please let me know). There have been a few other physical Turing machines like the Logo of Doom, but none were immediately recognizable as Turing machines. As I am always looking for a new challenge, I set out to build what you see here.'"

Apple Orders 10 Million Tablets? 221

Arvisp writes "According to a blog post by former Google China president Kai-Fu Lee, Apple plans to produce nearly 10 million tablets in the still-unannounced product's first year. If Lee's blog post is to be believed, Apple plans to sell nearly twice as many tablets as it did iPhones in the product's first year."

Null-Prefix SSL Certificate For PayPal Released 351

An anonymous reader writes "Nine weeks after Moxie Marlinspike presented at Defcon 17, null-prefix certificates that exploit the SSL certificate vulnerability are beginning to appear. Yesterday, someone posted a null-prefix certificate for www.paypal.com on the full-disclosure mailing list. In conjunction with sslsniff, this certificate can be used to intercept communication to PayPal from all clients using the Windows Crypto API, for which a patch is still not available. This includes IE, Chrome, and Safari on Windows. What's worse, because of the OCSP attack that Moxie also presented at Defcon, this certificate cannot be revoked." Update: 10/06 23:19 GMT by KD: Now it seems that PayPal has suspended Marlinspike's account.

New Graphical Representation of the Periodic Table 140

KentuckyFC writes "The great power of Mendeleev's periodic table was that it allowed him to predict the properties of undiscovered elements. But can this arrangement be improved? Two new envisionings of the periodic table attempt to do just that. The first uses a new graphical representation that shows the relative sizes of atoms as well as their groups and periods. The other uses the same kind of group theoretical approach that particle physicists developed to classify particles by their symmetries (abstract). That helped particle physicists predict the existence of new particles, but may have limited utility for chemists who seem to have discovered (or predicted) all of the elements they need already."

Google Finds DRAM Errors More Common Than Believed 333

An anonymous reader writes "A Google study of DRAM errors in their data centers found that they are hundreds to thousands of times more common than has been previously believed. Hard errors may be the most common failure type. The DIMMs themselves appear to be of good quality, and bad mobo design may be the biggest problem." Here is the study (PDF), which Google engineers published with a researcher from the University of Toronto.

Thawte Will End "Web of Trust" On November 16 127

An anonymous reader writes "Thawte is ending their Web of Trust, including their free Personal Email Certificates, in less than 2 weeks' time. This hasn't been picked up by the media yet. Seems to me a lot of people, including myself, are hurt by this." Thawte is offering a 1-year free VeriSign cert to those holding valid Personal Email Certificates; after that you pay.

Comment You're doing it wrong (Score 1) 156

The people running this election missed the point and thus all the benefits of internet voting. The name of the game is turnout. For that you need to give the electorate the widest array of simple options. First, there wasn't much simple about the solution provided by the UK\Australian company (Everyone Counts) that supplied the internet voting software. The voting system, even with the drastically low turnout was overwhelmed and slow response times and timeouts. Further the system used a java applet as a security solution, which just adds to the incompatibility problems.

The largest folly with this election though is that they forced internet voting on the electorate. Internet voting is about giving people additional options, not restricting them. The bottom line is crap technology and poor decisions can kill any project.

Submission + - The First Federally Certified Voting System (electiontechnology.com)

InternetVoting writes: "The Election Assistance Commission has announced the the first ever federally certified voting system.While the Election Management System (EMS) 4.0 by MicroVote General Corporation has successfully completed 17 months of testing, many questions still remain about the United States voting system Testing and Certification program. Many systems are still being tested to obsolete standards, the current standards are set to become obsolete soon and cost estimates for future certifications are skyrocketing. The future of improved innovating voting systems does not look bright."

Submission + - Obama Keeps His Blackberry (electiontechnology.com)

InternetVoting writes: "After all the controversy surrounding Obama's Blackberry, word has come that he will get to keep it. Few details are available and neither the National Security Agency nor the White House are talking. The current rumor is that the Blackberry will be used exclusively for personal use and a Sectera Edge will be used for official communications."

Yes, I understand the CBO guesses around $1 million, but CBO estimates are by no means a guarantee. The federal government doesn't have a great track record with funding the research provisions in reform bills. (HAVA still hasn't been fully funded, largely the research aspects) NIST isn't a person and NIST has made no such statements. If you're referring to the Draft White Paper on SI, that was largely dismissed and did not represent NIST policy. If not, please cite your reference.

Submission + - U.S. Voting Machines Standards Open To Public (eac.gov)

Online Voting writes: "The U.S. Election Assistance Commission has published new voting systems testing and certification standards for 190 days of public comment. For all the critics of electronic voting, this is your opportunity to improve the process. This will be the second version of the federal voting system standards (the first version is the VVSG 05). To learn more about these Voluntary Voting System Standards see this FAQ."

Submission + - Court Upholds Internet Deregulation (law.com)

Internet Voting writes: "Big telecom companies seem to have won big with the 3rd U.S. Circuit Court of Appeals ruling upholding FCC's ruling deregulating the Internet. Opponents argued that telecoms could now deny third parties access to their telecommunications lines and eliminating competition. From the story: "In its September 2005 ruling, the FCC relieved telephone companies of decades-old regulations that required them to grant competing Internet service providers "nondiscriminatory" access to their wirelines in order to reach consumers.""
