  1. Re:Am I understanding this correctly? on Yahoo DMARC Implementation Breaks Most Mailing Lists · · Score: 3, Insightful

    It's not blocking relayed mail in the usual sense. Most mailing lists use the original poster's email address as the FROM field so everyone on the list knows who posted the message. The SENDER field contains the actual list address. And that should match the sending server's IP address. So reverse DNS and SPF (and DKIM if enabled) will validate the SENDER as the list server software. The REPLY TO will be either the list or the original poster, depending on list policy. DMARC requires that the FROM field also match the sending server, and ignores SPF and DKIM.

  2. Re:Totally pointless. on US Carriers Said To Have Rejected Kill Switch Technology Last Year · · Score: 1

    The second way, and probably a preferable one, is to make the bricking recoverable by the end user, who must enter a password that they chose for their phone to unbrick the device. The password should not be of any pre-determinable length so that a hacker who wanted to unbrick the phone would not even know what the domain to try to guess the password by brute force might be. Ideally, such a password should not get reset simply by changing the sim card in the device, and changing it would require that the old password be entered first.

    A bricked phone would be utterly useless for virtually any task... even using the apps that might be installed on it... the only thing it would be able to do is call emergency/911, which would remove much of the incentive to bother to steal phones.

    That's exactly the way Activation Lock on the iPhone works. The lock is actually in Apple's activation servers and tied to the owner's iCloud ID and password, so wiping the phone does not get around the lock. When its serial number attempts to re-activate the phone it fails to activate. The only way around it is to know the owner's Apple ID and password. So having a secure password is an essential element in securing an iPhone, iPad or Mac (Activation lock works with all of them).

  3. Re:Faster to AWS than Linode on Reason To Hope Carriers Won't Win the War On Netflix · · Score: 1

    I'm on FIOS with their 50 down/25 up plan. Linode in Newark is 48Mbps, AWS East is 60Mbps. Just saying that a particular path is slow doesn't mean that it's Verizon interfering - it's more likely something else that's causing the problem.

    I was able to duplicate your results with my FIOS 50 down/35 up plan). Speed to AWS was FASTER than the benchmark speed test (60 Mbps for AWS, 48 for the benchmark, 50 Mbps for Linode). If this is throttling they're doing it wrong. I repeated it several times and got similar results.

    Correct; In the wild each set of teeth lasts about 10 years, because there's a lot of silica in the grasses that are an elephant's primary diet. Elephants in captivity can live longer because their diet is less abrasive to their teeth.

    why do humans have more oral problems compared to other species in nature?

    Could it be because we live longer than other species? By the time I had my first cavity my dog was dead.

    It's not even clear that we have more oral problems than other species. My current cat has serious dental disease. And elephants, if they aren't killed by us or disease, usually die indirectly of dental deterioration; their teeth wear out, then can no longer chew, and they die of starvation. Usually around the age of 60.

  7. This is a non-story; I guess it was a slow news da on iOS 6.1 Leads To Battery Life Drain, Overheating For iPhone Users · · Score: 1

    The issues with 6.1 are no different from scattered reports of issues for every release of iOS that has ever come out. There are a few phones after each release that eat battery fast or have other problems, and there are easy solutions posted on many sites as well as Apple support fora. No problems with iOS 6.1 on my phone.

  8. Re:In other words... on NYC Police Gathering Cellphone Logs · · Score: 1

    Well, there's more to it than that if you read far enough into the story. The police subpoena phone records by phone number, not IMEI. So if the victim transfers the number to another phone the victim's calls are in the database, not the thief's.

    Interesting question, but since the advent of the Essex class carrier in 1941 no US carrier of Essex class or later has ever been sunk. USS Intrepid in the course of WW II took a torpedo and 5 Kamikaze hits at different times, and was repaired and back in service weeks after each attack.

    Carriers are also:
    * Mobile hospitals.
    * Mobile power generation units.
    * Mobile food services.
    And I'm sure that people here can think of a few more. Carriers cannot be fully replaced.

    This is a really good point, and the most common use of carriers in the US fleet. Also for providing fresh water in emergencies (such as Haiti), as mentioned in a followup post.

What does the choice of operating system have to do with essentially exposing data outside of the corporate firewall? Cloud storage and choice of operating system have nothing to do with each other. All that have appeared are the usual knee-jerk responses defending or attacking various operating systems.

  16. Re:there is no good definition of "species" on Were Neanderthals Devoured By Humans? · · Score: 1

    The problem is that undergraduate bio, like undergraduate calculus, has to oversimplify because you need to understand more advanced concepts before the basic concepts are clear. There are excellent definitions of "species" that are understood by biologists. The details are of interest primarily to evolutionary biologists, but a reading of almost any work by Ernst Mayr will reveal to you how scientists define species.

    Given that, most of your points are irrelevant, because the scientific definitions take them into account. You can eliminate most of them by simply noting that a mating between fertile members of the community with the other sex is a condition for the definition. Scientists think this is so obvious they don't bother to state it.

    The one point that scientists disagree on is whether two individuals that could produce viable offspring but don't because their environments don't overlap are the same species. One of Mayr's examples is domestic dogs and wolves. One lives in the wild, the other in your house, so their environments don't overlap. So they may or may not be the same species. Another is animals that live on different continents. These are frequently called different species because they will evolve independently, and even if they could produce viable offspring today at some point in the future they probably couldn't.

    Asexual organisms have a different definition of species; the one you learned in biology is only for organisms that reproduce sexually. Likewise for parthenogenesis.

    Maintaining focus is not difficult. You can get an inexpensive drive for your telescope today that will keep a chosen stellar object centered in the objective for many hours. Fancier ones have kept orbiting telescopes focused on a region of space for weeks or months. The same technology can keep a lens focused on the sun. The sun's movement is highly predictable so it isn't even necessary to have a feedback loop (although that could improve it even more).

  23. Russian researcher's comments on Tunguska Blast Was a Small Asteroid · · Score: 1
    Here's Russian Tunguska researcher Andrei Ol'khovatov's take on this "new" discovery

    QUOTE (with minor editing for grammar): 98. December 19, 2007 There is a press-release [at] http://www.sandia.gov/news/resources/releases/2007/asteroid.html on Sandia researcher Mark Boslough calculations of Tunguska. There are some computer graphics, but there is practically no info on physical models on which the calculations are based!

    I can say that the graphics resembled [to] me the one in their calculations presented in 1995! And what I read (in his 1995 paper) on the sparse info about the models is not convincing.

    Moreover one of the calculations' outcome was a proposal that satellites in orbits are in danger due to 'plumes' from rather small meteoroids ('meteorites')! (see the Boslough's abstract on Tunguska-96 conference here: http://www-th.bo.infn.it/tunguska/abstr3.html ).

    Interesting that several groups of researchers using 'the most advanced' computer calculations obtain rather different results! :) But there is one point [on] which I could agree with Boslough -- the strength of the forest [destruction] used to be overestimated indeed, but in reality it should be incorporated into calculations in much more complicated form than Boslough has done. In my opinion this would alter the results of the calculations completely. :UNQUOTE

  24. AT&T was great on AT&T Vs. Apple Store At the iPhone Launch · · Score: 1

    I had no trouble getting an iPhone at an AT&T store. True, it was the 3rd one I tried that had not run out, but that one had a huge inventory and a short line (5 minutes). As I needed to migrate from an older AT&T contract it was the only place to go. The store had about a dozen reps, and all seemed to be knowledgeable and helpful. My rep pointed out that it would be cheaper to add the iPhone to an existing contract than to get a new iPhone-specific contract; in fact, it was also cheaper than my current Treo plan. So she first migrated my old, grandfathered Original AT&T Wireless to a New AT&T family plan, threw in 3 LG 3G phones (free) for my 3 lines, then sold me the iPhone. Apple could simply not have done this. When I got the iPhone home I registered in on iTunes, adding it to the new plan. My monthly charges will be about $20 less than they were with the old plan and Treo. That will pay for the iPhone pretty quickly, compared to a new Treo. And I now have an extra LG.
