    we didn't relinquish control of Iraq until we were sure that relatively secular, pro-western leaders were going to take over. You are speaking in the past tense of something that may or not happen in the future.

    And we damn sure should have done the same thing in Afghanistan, especially if we cared about the potential for them to become future terrorist producers/trainers/harborers. How? Iraq apparently can't be ruled even with more than 100,000 troops. It's mostly nice and flat, with few places to hide. How are you going to impose something on Afghanistan with far fewer troops in a much more difficult area?

    We should have written the constitution and the law books as the US did in Japan after WWII, with some minor input by the Afghanis The Japanese knew that they were beaten in a war they started themselves. They knew they'd have to do as the victors demanded. This mindset is completely different from that of the Afghani people.

    I don't see how the existing conspiracy theory of "They cut the cable so they could install monitoring equipment" possibly makes sense. Especially since you don't actually CUT cables in order to tap them.

    To install a tap on a circuit, you need to first cut or break into it if it's a fiber-optic cable. Wrong. Fiber-optic cables can be tapped simply by bending them. The "simply" bit gets a bit harder when you have to do it beneath the sea, of course.

    Even if it is $1.00 a year, it is still more then what I currently pay for the private lan and a non-static DSL connection. As I said, you already have a /48. It changes whenever your IPv4 address changes, which can be a bit inconvenient, but no more inconvenient than non-static IPv4 is already.

    No. The security implications of every single device being connected to one big WAN are obvious. They are? What stops you from applying policy to WAN connections? With WAN connections, you don't have a big trusted broadcast domain where trojans can run wild.

    (although I was thinking more of a cable with RJ45 plugs at regular intervals). That won't work. UTP (and STP) is fundamentally point-to-point. The only way you could do it would be to make a little 3-port hub -- unfortunately ethernet hubs need power, so that would look a bit silly.

    How much is it going to cost per month or year to have a public ipv6 address.

    If you have an IPv6 address today, you automatically have a /48 IPv6 as well.

  13. Re:Seems normal. on Vint Cerf on Why TCP/IP Was So Long in Coming · · Score: 1

    The virtual circuits costing issue is presumably part of why MPLS is also somewhat of a rarity.

    Is MPLS that much of a rarity? Business point-to-point or point-to-multipoint lines around here tend to be delivered either by MPLS or 802.1ah. Most MPLS-based lines are generally more expensive than raw Internet lines, but that's simply because MPLS is awfully expensive per VRF, so providers don't like having lots of VRF's.

    (Of course it's also possible to do virtual routing without MPLS. That's how I make a living)

  14. Re:Adam Smith sez... on The True Cost of SMS Messages · · Score: 2, Informative

    Personally, I think this is more of a time issue. When dealing with heavier traffic, you have to respond, and required response time may not leave time for signaling or other kinds of politeness. If you don't have time to signal, you certainly should not do the maneuver. The obvious exception is if the maneuver is necessary to avoid collision, but if you find yourself doing emergency maneuvers on a regular basis, you should reconsider your driving style.

  16. Re:Breaking the network is easy on iPhone Application Key Leaked · · Score: 1

    It's difficult with a phone, but it becomes easier when you write software that runs on hundreds of thousands or millions of phones. Write an e-mail client which checks mail every hour. Forget to randomize when that occurs every hour. Next time the check triggers, millions of phones access the network at the same time. And that was that. It's unlikely that such an error would bring more than a minor section of the network down -- then the problem would be noticed and fixed before the software is widely deployed. Also, do you really think that Apple inspects third party software to the extent where they would find such a bug?

    It has everything to do with protecting the phone network which *IS* their responsibility to repair when trashed. Users be damned when it comes to breaking the phone but break the network, we can't have that!

    It is quite difficult to break the phone network with a phone, especially when you can't mess with the actual GSM/EDGE chip but only the one running programs. If that's the excuse to lock the phone, it's a seriously bad one.

    If Sun had gone open source early with their Unix, they would have stole the show.

    It's possible that Sun could have prevented Linux from being a success, and perhaps even from being started at all. I believe that corporate politics would have ruined it -- very few companies are willing to let their product go enough that it transcends them. Look at the free software that came out of companies: MySQL, OpenOffice.org, Asterisk, QT. They're still pretty much controlled by those companies. Firefox is an exception only because the parent company pretty much forgot about it.

    Likewise, if Sun had 'gotten it' way back then, OpenSolaris would be what Linux is today, Linux wouldn't exist, and Sun would be making a fortune.

    I doubt it. It would have taken a lot more than a license change to keep Solaris relevant. BSD was available at the time, but didn't have a unifying figure like Linus Torvalds to rally around -- Solaris would have had the same problem.

    In order to attach a probe to an asteroid you'd have to rendezvous with it, which means you'd be in the same orbit as it is anyway. No fuel saved.

    I'm no physicist, but the Heisenberg uncertainty principle for starters, which forces you to choose between knowing a particle's location and its momentum, probably rules out even simple multi-atom structures.
