  1. Asking the right questions on Google vs. Bing — a Quasi-Empirical Study · · Score: 1

    Acting as if I really wanted to know the answer, I tried the Google query, chose the first hit, which was the product page for the Frigidaire FPHC2398LF (at this point if I were really doing this I would have had the clue to enter my own model number), which below the flash stuff has a navigation bar that has a button for Guides/Manuals. Click on that, click on download the English User Guide which is a PDF, and "Bing!" there in the table of contents is has "Changing the Filter" on page 15

    The Bing hits for the question has as the first hit the home page of the Frigidaire web site. If I went there maybe I would think to click on the filters & accessories tab, which is a blind alley for this. Maybe I would click on the Refrigerators link and get clue that I want to look for my own model number and eventually get to that same page that was Google's first hit. The other hits on Bing had a number of reviews and links for Frigidaire appliances other than refrigerators.

    I guess I would rank Google and Bing as being equally useless if I ask a question that is not specific enough to give the exact answer I want and if I am too clueless to use the results I get to track down the answer or figure out how to refine the question. In this case, Google got me about two clicks from the exact answer, Bing got me pretty much nowhere.

    If as a result of this experience I realize that what I really want to search for the user manual, and next time I try that, and also indicate that I want a professional series refrigerator rather than, say, an oven, (search term frigidaire professional series refrigerator user manual) Google gets me results on the Frigidaire web site in the first two hits, Bing gets all third party sites and reviews on their first page of hits.

  3. My 10 yr old likes Scratch on Best Introduction To Programming For Bright 11-14-Year-Olds? · · Score: 1

    My 10 year old started with LOGO, a commercial version called MicroWorlds EX. That would be a good one to try if you have the budget to buy a classroom license. He tried Alice, but didn't care for it much because of limitations on what he could do with it.

    He now spends most of his time on Scratch, I think mostly because he gets to upload projects to the Scratch website and share with friends he has made there. Since Scratch is free, teaches all the fundamental principles of programming languages without warping the brain as Basic would, and allows one to immediately create cool graphics stuff and collaborate with other kids, I would recommend it. http://scratch.mit.edu/

    Lately he has also started hacking a Javascript tutorial because he wants to learn how to make web pages that do interesting things. I don't think it would be a good first programming language, but you might keep it in mind as an adjunct to a first course. Motivation is as important as the language, and being able to create cool stuff provides that.

  6. MIT announcement: Tuition-free for 30% of students on Scholarships From FOSS Organizations? · · Score: 3, Informative
    MIT announced in a press release a couple of weeks ago that they are increasing financial aid so that the school will be tuition-free for the nearly 30% of undergraduate students whose families earn less than $75,000 per year, with no expectation of student loans to cover non-tuition expenses. There are other changes that affect students whose families are in higher income brackets, with details in the press release.

    Here is one significant quote from it:

    For those receiving an MIT scholarship, which is six out of every 10 MIT undergraduates, net tuition is $8,100--an amount that approximates the in-state cost of many public universities

    Lastly, not all public key crypto is shafted, only things that rely on factorisation as a problem. ECC will be quite safe until (if?) somebody develops a quantum algorithm for discrete logs
    Shor also describes a quantum algorithm for solving the discrete log problem in polynomial time, although I don't see any references for anyone having implemented it in a physical experiment like this one with quantum factorization.

  9. The original research article (and why it's bogus) on People Trust Yahoo! and Google For the Brands · · Score: 2, Informative

    Here's a link to the original article at the author's site that unlike the ACM digital library version is not locked up behind a subscription requirement: The Effect of Brand Awareness on the Evaluation of Search Engine Results [PDF]

    Here's a more understandable summary that in TFA: They got Google search results on four e-commerce topics, stripped identifying HTML, and created 16 fake results pages with branded header and footers for four search engines The query results for a topic had identical content and presentation. They presented each of 32 test subjects four results pages, one for each topic. Which of the four brands each was shown and in what order the topics were presented were randomized. Subjects looked at each result one at a time. They were asked to evaluate the results, following links as they chose to and commenting out loud. Note that all results sections were identical is both content and format, with only the branded page header and footers being different.

    The authors claim that Yahoo got the highest ratings (averaged over all four topic queries), 15.3% more than the overall average, compared to Google's 0.7% over average. But their table and graphs show results all over the map. Google scored 52.2% over average on the home improvement query. MSN had the highest score on the camping mexico query, Yahoo was highest on techno music, and the made up unknown search engine got the highest score on the laser removal query. That says to me that when you have four search engines and four queries to mix together in random order you need a lot more than 32 subjects to get statistically meaningful results. The paper contains no analysis of statistical significance of the results.

  10. Re:Speed of light? on Simple Comm Technique Beats Quantum Crypto · · Score: 1

    That proposed attack is rebutted by Kish in Response to Scheuer-Yariv: "A Classical Key-Distribution System based on Johnson (like) noise -How Secure?" and Response to Feng Hao's paper "Kish's key exchange scheme is insecure".

    Basically he specifies that the frequency one switches the resistors has to be kept below a certain limit and low pass filters used at each end to prevent attacks using injection of high frequency signals. He shows that below threshold frequencies, the eavesdropper gets statistically worse information from the sniffing devices than do Alice and Bob to a significant enough degree that the information leakage is less than you get from a practical quantum cryptographic system.

    A small amount of information leakage is tolerable... Quantum crypto systems in practice have some. Privacy enhancing algorithms are used to achieve practical security from a slightly leaky system at the expense of bandwidth, and those would work the same way for this system as for quantum crypto.

  11. Old news: Broken, rebutted, broken, rebutted again on Simple Comm Technique Beats Quantum Crypto · · Score: 2, Informative

    The original article was published (and talked about in /., see Related Article link) back in 2005. The paper you cited claiming a break was replied to by the original author, and there have been a number of other papers back and forth since. The technique has credibility. As Bruce Schneier pointed out this technique if it works is no worse than quantum cryptography and is a lot simpler and cheaper, but it has all the other deficiencies of quantum cryptography. The author claims no more than that. He rebuts the arguments in the paper you linked to by showing that the amount of information leakage is less than that from a practical (as opposed to theoretically ideal) quantum cryptography system, and so can be dealt with using the same privacy-enhancing post-processing that has to be used with quantum crypto.

    I agree with Schneier's assessment of quantum crypto as a solution in search of a problem, and this appears the same, although much cheaper to implement.

    The most recent paper on the topic was a plenary talk given by the author last week at a conference in Italy. The references in that paper will give you the complete list of papers arguing with his results and his responses to those arguments.

    PUBPAT has a different spin on this story, touting how Forgent has dropped all claims on the patent as a result of a successful challenge brought a year ago by PUBPAT resulting in the patent office rejecting the broadest claims last May. However, the details of the patent show that it was issued in 1987, which would mean that it expires sometime in 2007. So Forgent just settled for a final $8 million to cap off the total $110 million in revenue they have grabbed during the 10 years since they bought the company that owned the patent.

  15. Re:A factor of 0.8 decreases traffic on Traversing the "Googlearchy" · · Score: 3, Informative

    TFA says that it is a linear relationship with a slope of 0.8. They scaled the data so that a direct linear relationship would plot as a straight line with a slope of 1, which is a line going up at a 45 degree angle, hits increasing one unit for every one unit increase in incoming links.

    Instead they saw a straight line with a slope of 0.8, meaning the hits increase 0.8 units for every 1 unit increase in incoming links. More links still correlate with more traffic, but, for example, doubling the number of incoming links increases the traffic by a factor of 1.6, not by a factor of 2.

    Why not use Blue Security's hashed "do not intrude" list?

    Your own journal entry demonstrates how Blue Security's Blue Frog software can't work on much of the spam. And there are other reasons why it can't work on most spam. After reading Blue Security's FAQ, I see the following six fallacies, just off the top of my head... Actually they can be summarized as, "How can you possibly expect automated complaints to a form on a spamvertised website (if there even is a feedback or complaint form) will shame a spammer into not spamming as long as they continue to turn a profit from it?"

    1) much spam does not include URLs to websites; 2) if the spam is advertising a web site, there is no reason for the owner to even have a form for opting out of their spam mailings or for complaints or feedback; 3) if Blue Frog is at all successful there is no way they can manually identify spamvertised web sites and the complaint link for each and prepare a script to automate filing a complaint to the particular form used by each; 4) if a spamvertised web site does have a customer feedback or request form they have no reason to not simply delete complaints about spam; 5) even if they cared a tiny bit, they have no control over who the spam mailing service they hired (who could even be connected to the Russian Mafia) actually sends spam to; 6) the spam mailing services get paid to send X million emails, not to send X million emails to valid addresses of people who have not indicated that they don't want spam. Their customers pay for the results they get and don't care how much wasted email is used to get the results. The spam mailing service has no reason to conserve bandwidth when they are using botnets of infected machines to do the actual work.

    That's the same circuit mentioned in the recent transparent IC story where TFA said

    The modeling software they used is called NAMD, free open source "parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems" that will run on commodity clusters of tens of Linux PCs on gigabit ethernet. In other words, you too can run the virus simulation on your own Beowulf cluster, if you don't mind it taking some years to run.

  19. Short explanation if you're too lazy to RTFA on Security Flaw Discovered in GPG · · Score: 4, Informative

    The bug allows someone to take a signed GPG message, stick in their own unsigned message in a certain way, and GPG will show you the combined message or even just the new message, but tell you that it is signed by the person who signed the original message.

    If you read the message using the new GPG 1.4.2.2 it will correctly not accept the hacked message. So if you have any question about signed mail you received, you can check it again after upgrading GPG.

    The bug only affects embedded signatures, such as in email messages using inline signatures or signed encrypted email. I think that excludes PGP/MIME signed unencrypted email, which is a common format for signed mail and would be a form of detached signature.

    The bug does not affect "detached signatures", which are the kind that are used to verify software downloads, which means it could not have been used to hack yum, apt-get, etc.

    All in all, not a big security flaw unless someone takes a signed email that you sent them, forges a GPG signed request to your domain registrar to transfer your million dollar domain name to them, and your registrar hasn't yet updated to GPG 1.4.2.2. Whoops -- if you upgrade GPG right now, it wouldn't help in that scenario.
