    Losing domain names is a real worry, since several businesses actively snap up unused domain names in bulk and hold them for ransom.

    If I have to maintain a domain name to maintain redelegability of my underlying OpenID provider, that's going to be a real problem.

    And won't somebody snapping up my or my blog's domain name be able to steal my identity as well now? That's decidedly awful (far worse than losing your email address) if your bank or credit card provider is using OpenID.

    Is there something I'm missing? (hopefully?)

    There are plenty of cultural and technological differences - Aristotle simply assumes women are inferior - but I keep imagining Aristotle or the center-right politician Thucydides having drinks with the similarly bigoted, and much more recent Adams, Washington, and Hamilton. I think they'd get along easily, grumbling about the servants and women.

    That happens alot. But despite that there are still
    plenty of people with one choice, for a variety of structural
    reasons ranging from being between wireless ISP startups to
    fatal troubles getting the telco to set up the sizeable wire to
    the Internet proper, to just plain bad luck.

    Plus, it takes three entrants to make a robust market, and 95+% of
    the populace is in a place with no more than two provider choices,
    because wireless can't compete where cable and DSL are both present.
    That means choice might not help you.

    IMHO the correct solution is to deregulate bandwidth. I think this
    country right now loses more money than it gains by having monopoly
    telco or cable carriers. But that's long, hard sell.

  12. Pointer to Long Post on Why They're Wrong on HD Video Could 'Choke the Internet'? · · Score: 1

    It's just a few monopoly carriers trying to blow smoke to cover their attempted change of the ruleset that has allowed the Internet to grow, not a wide set of ISPs saying this.

    I wrote a long post that explains network neutrality issues in detail. The truth is that ISPs are already charging for and being paid for the network they're providing. If they need to raise fees on broadband users to support higher bandwidth consumption, they can and do.

    It's important, though, that they not be allowed to change the rules to try and also collect from content providers. These monopolies are being foolish, of course, because if the rules changed, there'd almost certainly be less of an Internet economy to collect bandwidth fees from.

  13. ukernels are hard to code on Microkernel: The Comeback? · · Score: 2, Insightful

    I played alot with AmigaDOS, a message-passing OS (it was a port of Tripos, an early research message-passing OS), as a teenager. That experience cured me of message-passing interest, because I found myself spending 75% of my time dealing with message-passing coding rather than dealing with the underlying hacks I was trying to perpetrate.

    Not only did one have to write more code to make an MP call (comm overhead code), but the bugs had a way of showing up in that snippet and being harder to debug. The tiniest change in a driver's interface meant an hour of coding, vs the ten minutes I saw later for BSD Unix. At that, I was lucky. If I'd been dealing much with nontrivial synchronization and threading, I expect I would've seen more like the factor of ten coding slowdown I've always seen dealing with threading problems (and to be fair, most ukernel code doesn't have to either, it's just that there are more threads, more sync points, and thus more potential for trouble).

    The basic problem is that modularization is a largely orthogonal problem from threading, address spaces, or messaging. If you split up modules into different threads, then now you don't just have to solve modularization, but you also have to solve threading, messaging, and address space problems, too. Now, address space separation seems like it might save some debugging troubles, and in fact, successful "monolithic" operating systems in fact deliver the simplest form of that. I've been a little surprised that attempts to push farther on that like Electric Fence or multi-address-space OS' with traditional system call architectures have gone nowhere. But they have, so the difficulties must exceed the return somehow.

    Thus, I haven't been surprised to see ukernel project after ukernel project fail. The idea is at least forty years old, and has seen many smart people try to take it on - if a ukernel was going to succeed broadly, it would've happened by now.

    If you like ukernel OS' even after reading this, I say go try one, and try hacking something in. Just watch how much time you spend actually writing code implementing the hack vs MPI / threading drudgery.

    > QoS is the worst thing that the IETF has ever collaborated on.

    No, it isn't. QoS is a completely reasonable architecture. It's the only way you can get guaranteed-good-quality audio and video over the Internet to people willing to pay, which is a good thing. And it's completely orthogonal to the realities of your situation, since Vonage doesn't directly use QoS. This is about treatment of best-effort traffic. And that's BellSouth and Comcast want to start discriminating against.

    If your provider is discrimatorially dropping traffic for which it has bandwidth of a particular type for reasons other than misbehavior, you can almost certainly haul him into court for breach of contract. They said they'd provide a service, and they aren't providing it.

    It's very hard to be BOTH CEO and CTO. The jobs are too different. So one dimension of your decision should be, do you have somebody good and in town and definitely lined up to be CTO if you run things?

    Oh, and if the biz guy ISN'T CEO, then IMHO you want to make him COO. Look at Ballmer. He was a great COO, even if a horrible CEO.

    If the CTO thing isn't a problem, you should think about which of you has a deeper grasp of things. That's why Gates was so good at it, even though he started with more of a programmer POV. It's true that you spend most of your time selling, but that didn't stop Gates, and understanding things is a big plus to selling big.

    I knew a physics Ph.D who finished and was so discouraged that he immediately started from scratch as a premed. He had talent and drive, too; it wasn't a case of him being marginal for the field.

    To my non-climate-scientist eye, an upward redistribution of energy seems a likelier theory than balanced warming/cooling for four reasons:

    1) It would be quite a coincidence for two such different mechanisms to just coincidentally have the same magnitude. Especially since the best-regarded warming models have orders of magnitude lower results.

    2) Energy redistributed high in the atmosphere would explain the observed ground data of observed weather changes with modest temperature change.
