  1. Re:Source? on Microsoft Has No Plans To Patch New Flaw · · Score: 5, Informative

    there is no link here to any article that claims Microsoft has no plans to patch the flaw.

    To be fair the summary states

    it has no plans to patch the flaw right now

    Which is in the 2nd link actually.

    Microsoft said it is investigating the flaw and looking at possible solutions, however there was no clear indication that the company intends to patch the flaw in the near future.

    Well, from that quote to the summary, there is quite a stretch, but what did you expect ?

    For any given sample, 1/10th of them will be necessary.

    I'm sorry but you're wrong. That's not how stats are working.

    Let's play heads or tails.
    Each toss has a 50% chance of being heads.
    According to you, for any number of tosses, 50% of them will be heads. In other words, you're saying that there is a 100% chance that half of them will be heads.

    For a sample of two tosses, that would mean a 100% probability of one head(s) and one tail(s).
    I hope that you see how this is wrong. You would actually have 50% probability of one head and one tail, 25% probability of two heads, 25% probability of two tails.

    For a sample of size n, 10% probability for a piece of data to be necessary, the correct formula says that the probability for at least one element of the sample to be necessary is 1-(0.9^n), which quickly approches 1 (100%) as n increases.

    Now, a MUCH more useful set of data is probability over time. 1/10 within 10 years? 5 years? 1 week?

    It depends of what you mean by probability over time. What I can tell you is that as more time elpases, the probability of an element to be necessary (more correctly, to having been necessary) increases. The 90% never read is supposedly for an infinity of time (that's what "never" means, right ?).

  4. Re:Which 90% ? on Dell Says 90% of Recorded Business Data Is Never Read · · Score: 3, Interesting

    If each piece of data has 90% probability of not beaing read again...

    You discard only 10 pieces out of 100, or out of 1 billion, whatever...

    The probability that none of these 10 pieces of data would have ever been needed again is 0.9^10 = 0.348 = 34.8%

    Which means that you keep all of your data.

    Caveats :

    • This assumes that all pieces have equal interest (but maybe you store a field that the interface doesn't allow you to retrieve).
    • Assuming a random access on the 10% used, if you remove 10 out of 100, you have a much more important retrieve failure than if you remove 10 out of a billion. Some retrieve failure rate could be acceptable.

    You can apparently make a DE-9 -> game port adapter relatively easily. That link isn't about an adapter, but a cable replacement. It might still be useful because the resistors are likely still needed when doing an adapter.

    That's where I will stop (as I have plenty of hardware with game ports), but you can find off-the-shelf game port -> USB converters for an easy solution.

  12. DMCA is a copyright law on Tetris Clones Pulled From Android Market · · Score: 1

    DMCA is about copyright, not patents, so they shouldn't take down your application for presumed patent infringement. Tetris shouldn't be patentable anyway, but I wouldn't bet on what the USPTO would actually patent, whatever their policies are stating.

    Write to Google that you own the copyright on your application and that The Tetris Company, LLC claims are illegitimate.

    From the wikipedia :

    Takedown notices targeting a competing business made up over half (57%) of the notices Google has received, the company said, and more than one-third (37%), "were not valid copyright claims."

    I wrote my previous post under the misunderstanding that governmental agencies could get a copy of the original certificate private key, not that they could get a different private key with the same certification information.

    That second case of course mean that "trusted" certificates are neither better nor worse than self-signed certificate. This is a MITM attack that only works well in the case of a first connection (as you should be wary of a certificate change as long as the preexisting certificate didn't expire).

    In the first case, however, it would mean than the government could impersonate the certificate owner at any time, which is not possible with a self-signed certificate, as you're only ever giving the public key.

    This is of course overlooking the fact that you're not giving your private key to the certification organism either, but a certificate signing request.

Make one hundred dots representing the elements of the set M. The set C of the costs of production contains 20 fewer points than set M. Represent the set C as a subset of M, and answer the following question: 'What is the cardinality of the set P of profits?'"

    In 1980: "A logger sells a truckload of wood for $100. His cost of production is $80, and his profit is $20. Your assignment: underline the number 20."

    Not to me.

    [...]

    This tells us a few interesting things. We can guarantee detection of malware. And that includes zero-day attacks and rootkits.

    Even with your interpretation :

    We can even guarantee that we will detect malware that infected a device before we installed our detection program.

    You can't detect known malware that way if it virtualizes the computer, because you will only scan for the memory the malware is willing to show you.

    By the way, the following assumption is unworkable:

    Assume now that we have a detection algorithm that runs in kernel mode, and that swaps out everything in RAM. Everything except itself.

    You can't swap out many parts of the kernel.
    And I'm pretty sure kernel space parts of a rootkit won't let themselves swap out. Which does not mean uncooperative kernel modules are malware. If you're swapping out the disk driver, how will you get it back ? But maybe this exact disk driver is infected by the rootkit ?

    Or, there could be malware in RAM, not diverting read requests, and the checksum will be the expected result, and without a delay.

    The only problem with Markus Jakobsson grand theory is that all malware are of that last kind.
    Well, all malware since the memory protection era. I suppose his "product" could work for DOSes (but there is no multitasking there) Windows 3, MacOS9, AmigaOS and some embedded OSes.
    And if the malware does virtualization, he is located in a memory area that his product won't be able to scan anyway.

    So, simply put, it is a scam.
