  3. Re:100 gbps wavelength? on Comcast Kicks Tires On 100-Gig Optical Links · · Score: 5, Interesting
    If you read one of the linked articles, you'll learn that

    Unlike other trials that used 10 separate 10 Gbps wavelengths to carry 100 Gbps, the Verizon test utilized a 100 Gbps signal on a single wavelength. Other interesting things from that article:

    "This is another critical milestone on our way to ensuring that we have the most advanced telecom network technology at the right time, in the right place, to serve our customers," Having never used Comcast, I'll leave it to those who have to asses the meaning of "serve our customers".

    "The field trial also confirms optical networking's role as a critical enabler for competitive transformation, as new services and applications reshape network requirements." I thought peer-to-peer data transfer already "reshaped network requirements" and left the ISPs struggling to keep up.

    "Applications based on online video are clearly drivers for higher bandwidth [...]" Again, how about peer-to-peer transfer.

    "Transmission at 100 Gbps will enable low latency and significant improvement in real-time transaction. Trading institutions and other Verizon customers using real-time communications will find the associated performance very attractive." I can transfer 100 Gbps by putting hard disks in my backpack and running a short sprint. This is orthogonal to latency (which is what real-time is about). Okay, strawman. Assume the big fiber is deployed, and everybody uses it. Then you'll run into contention issues, and your packet will sit in a queue. I'm not saying bigger pipes won't help, but I want an arguement; right now, all I have is a claim.
  4. Re:Unknown value? on Happy Pi Day · · Score: 1

    But no system of representing numbers could express pi's relationship to 1 exactly without an infinite amount of information. Have a look at Computable Numbers. Brief version: a number x is computable if there exists a Turing machine (basically a program, should a reader be unaware) that when given a rational epsilon > 0 computes a rational r, such that |x - r| < epsilon.

    From the WP article:

    The computable numbers include many of the specific real numbers which appear in practice, including all algebraic numbers, as well as e, pi, and many other transcendental numbers. If you start from ZFC you typically construct the real numbers as Cauchy sequences of rationals, each sequence representing its limit. So, let's pick the constant sequence of rational zeroes to represent the real zero. How do you represent this with a finite amount of information? Is it different then, to represent numbers by Turing machines? If so, how?

    You don't define what you mean by "exactly" or "relationship", so I can't speak to that very well. How do you express 7's "relationship" to 142857 "exactly"?

  11. Observations and critique on Linux Foundation - We'd Love to Work with Microsoft · · Score: 2, Interesting
    A couple of critical observations:

    So you're starting to see OEMs pre-ship Linux for the first time [...] why are they doing that? [...] Is it because Linux is more functional than it's ever been? [...] yes, it is more functional. But that functionality combined with the economics [...]. [lots of ...] And so when companies like Dell or Asus or Lenovo or all these companies look at those profit margins, they say, "Why wouldn't I just create my own operating system and ship it with the device? Interesting. He argues for linux based primarily on price, and from the seller's viewpoint. Sure, some of the savings is (presumably) passed on to the consumer, but I miss a good argument for why the consumer should use it. He could have said "it does the same job for a lower price", which is a very convincing argument in my book (and to some extent also valid). It's not a very sexy argument, though, but I won't be demanding everything.

    InfoWorld: But Windows is still on 98, 99 per cent of PC desktops anyway, so do you think that number or that percentage will decrease?
    Zemlin: Yes. Yes, I think it will actually. As an extention of my previous comment, I wished InfoWorld would have asked him why he thinks that. I can say "I think I will get -1 Flamebait"; so what? It only becomes interesting when I have something to substantiate it with.

    If you're a Motorola or an LG, would you rather, per device basis when you're selling tens of millions of devices, license Windows Mobile or the Symbian platform from Nokia, or would you rather have Linux, which is collaboratively designed, which supports every major architecture? He's saying "Would you rather have a, or b, or c? Note that c has properties p and q." For a meaningful comparison, he could list some properties of a and b as well. Sure, we may know some of them, but he could have emphasised what he thinks is relevant. Also, when you've picked an architecture, support for any other architecture is not of much interest.

    InfoWorld: So are Microsoft's days as the dominant provider of desktop and server and maybe even handheld operating systems numbered?
    Zemlin: Monopolies don't last forever, so I mean, I think they've got a long way to go. It's just natural over time that people aren't going to allow a single company to dominate the market. People, as in individual consumers, always allow concentration of power; they don't care, they just want easy. Look at Microsoft; look at Google. People use their services because it's easy for them to do so. I'm conjecturing that it takes the power of the state to break up or prevent the formation of monopolies. Someone enlighten me: what happened with AT&T, Standard Oil and the Railroads? What's happening with Microsoft?

    InfoWorld: Wouldn't the emergence of Linux kind of say that maybe Microsoft never really was a monopoly, that there was always room for somebody else to compete in there and that's what Linux is now doing?
    Zemlin: It obviously was a desktop monopoly for a period of time. Again, there's a claim but no argument. I don't want to argue against him, I just want a better argument.

    Yes, the days of high-margin, vendor lock-in monopoly practices in the software business, yes, those are gone, and they're permanently gone. This is five minutes after he stated that Microsoft makes 30% profit; that doesn't like either dead or dying to me (sadly).

    InfoWorld: Can Solaris compete with Linux?
    Zemlin: [If Solaris was FLOSS eight years ago maybe, blah blah ...] Sure, that sounds plausible. What interests me is why Solaris (probably) won't be able to compete with Linux today. I'm guessing it's the network effects: with many users, it makes sense to develop for, and with much development, it makes sense to use.

    (None of this is to say that I disagree with Zemlin's assertions, just that I think he could have made a better argument).

    Package management and physical media are orthogonal.

    In particular, the CD from which I installed Ubuntu has tons of packages on it. You can have physical media without packages (say, Wii Sports), packages without physical media (that's what all the mirrors in my /etc/apt/sources.list are for) and no packages on no physical media: that's what your typical windows app is (winamp, winzip, winorlose).

    Making a game is expensive, so logically you want to release it to the biggest audience you can so that you can reap the most profit (or at the very least make enough to hit the break-even point). Windows, with 85% of the OS market, has the most promise of giving you the highest audience in PC gaming.
    No, not true.

    You say that making a game is expensive, and that's true; you also state that one wants to maximize profit, with which I can agree (you may want to maximize its first derivative, but let's assume not). You then claim that one gets the most profit by reaching the most users.

    How about shelling out $1 supporting Imaginary OS which has one user, and that user won't pay any money for your game? I'd say that's a net loss. Maximizing profit requires a cost-benefit analysis, not just a benefit analysis.

    It took THREE VERSIONS to come up with a layout idea that's been used in newspapers for books for literally centuries?!

    Web pages have infinite vertical space. Newspapers and books don't. Horizontal space is at a premium for web pages. It's not as important for newspapers and books. Unsurprisingly, a layout strategy that trades horizontal space for vertical space isn't a high priority for a technology primarily aimed at web pages. I wouldn't say that web standards that actually prioritise the web are nothing but "idiocy", I'd say that's entirely sensible.
    Let's see.

    Yes, I agree: vertical space is infinite and horizontal space is limited. Going from there straight to "no columns" is pulling a fast one, though: lines of text are generally easier to read--in particular the \r\n is easier, ISTR--when lines are roughly 66 characters long [1]. It's generally desirable to have as much text on the screen as possible. The only way of doing both 66 chars/line and packing the screen is by having several lines be adjacent; that is, by doing columns.

    One problem of columns is of course that unless you specify Everything (TM), you don't know how tall it's going to be; as it's very desirable not to have to scroll upwards, you're somewhat in a pickle.

    I'm toying with an idea for what I think I want: an option for a text block (p or div, no?) that means "show the text as follows: create as many columns of 66-char lines that will fit horizontally, and make them so tall that they take up almost all the screen. Repeat this for any remaining text". That should give the best of all worlds, but there might be issues.

    The facts and theories are the result of the scientific method and would be pretty much unthinkable without it.
    Yeah.

    Kinda. Depends on what you define the scientific method to be. [I'm reiterating a point made previously (http://science.slashdot.org/comments.pl?sid=466370&cid=22553660)]. New scientific knowledge (and let's not go out on a cartesian limb here) is the product of two major components, one of them being being the design and execution of experiments combined with peer review.

    The other is insights, ideas, and imaginations. There is no well-known algorithm, no "scientific method", by which we can generate ideas and infer connections in the data we observe. All we can do (as far as I know) is to take the ideas we generate and apply the first component, rigorous testing, to discard the ones of non-maximal usefulness.

    This is elegantly summed up in the phrase "It is not the purpose of science to produce infinite wisdom, but to guard against infinite folly" [citation needed] (linked post says Brecht).

    As an anecdotal example of what I'm talking about, it one day dawned on me that there must be a reason why code colouring is such a deal-breaking feature of editors (in the mind of most coders, at least), and that the reason is that colours are in some way perceived more readily (easier or faster). [That's the insight component]. Later, I listened to the an OCW intropsych lecture about visual perception, and indeed the lecturer made a few experiments (without the rigour part) with the class showing that:

    1. Finding a red circle in a blob of green ones is fast
    2. Finding a tee in a blob of ells is slow.
    3. Finding a tee in a blob of ells is fast if there's a red tee, no red ells and a bunch of green letters (my assumption about the details).

    Presumably, he could apply a bit of rigour and publish a peer-reviewed article containing "my" idea (only it's probably not that new by now).

    The important point is: how did I come up with the idea? It just sorta' popped into my head, and no methodology could reliably have produced that idea.
