  1. Re:IPv6 has tons of useless changes and 1 useful o on Why the Journey To IPv6 Is Still the Road Less Traveled · · Score: 1

    NAT mostly works, but it turns a lot of things that should 'just work' into a need to fiddle around with the router config.

    I don't see how. Either you keep essentially all ports open to your public IP at all times (bad idea), or you need to open ports on demand.

    The latter requires the same fiddling around with the router config as with NAT, assuming UPnP isn't used. If UPnP is enabled it's not an issue with NAT either and the whole point is moot.

  2. Good results on Ask Slashdot: What Features Would You Like In a Search Engine? · · Score: 1

    Without good results, it doesn't really matter about the bells and whistles. I use a search engine to find information, so it better do that extremely well. For example, I just couldn't stand using DuckDuckGo (aka Bing) because of this, and went back to Google. Bing consistently failed to find information the information I wanted, while Google had it on the first page.

    So, after your engine returns as good or, ideally, better results than Google, you can start thinking about other features.

    One feature I'd really like is to be able to tweak my result set. Something like if I search for "AC DC", I get a bunch of results about the band "AC/DC". That's not really a bad result given the input, but in this case I was after an explanation for the electrical terms.

    So I'm thinking some ability to mark one or more of the results I don't want and say "not pages like this", and it would cull those talking about the band, in a weighted manner. Or some other way to help me find the information I want when I search for some ambiguous terms.

    There's talk that they influenced the decision of some recommended constants for Elliptic Curve Cryptography.

    You'll want to use constants that ensures the cryptographic strength of the algorithm, so picking them are non-trivial and hence a recommended set was published. This is the same for most algorithms. AES has constants and they are part of what makes the algorithm AES and not some other variant.

    Anyway, here's what Bruce Schneier said about ECC:

    I no longer trust the constants. I believe the NSA has manipulated them through their relationships with industry.

    Meanwhile, all the other platforms for which LLVM would be the dominant platform and for which there aren't extant major backers are basically on the hook for whatever way LLVM wants to play it, including extinguishing support for their platform.

    No, really, I mean it. Explain in detail how FreeBSD will become utterly unusable if LLVM went closed-source today and deleted any FreeBSD related code from their now-internal repository. Or AMD's OpenCL implementation. Or any other project using LLVM.

    Sure, it's technically possible to start up a fork tomorrow. But, realistically, it's also just as possible to recreate MS Windows from scratch.

    That comparison is utterly silly. You already have the entire source code for LLVM, and forking it is simply pushing it to another repository. That's the complete opposite of Windows, where you'd have to recreate it from scratch.

    Well, either way, you're setting yourself up for the risk of the source going closed and you having to support development yourself.

    Well yes, but all that does is put you in the same spot as if you had picked a closed-source component to begin with.

    And don't think you're safe with GPL. Any GPL code can be re-licensed (and thus made closed-source) if the copyright holders agree. Of course, exactly as with BSD, the code already distributed under GPL/BSD will stay GPL/BSD.

    But they can't retroactively close the source, so I don't see how the "extinguish" part comes in. If the LLVM guys closes the source tomorrow it does not affect AMD, who's using LLVM for their OpenCL implementation. If it does, please elaborate, because I'm not seeing how.

    I'm ignoring patents because software patents are broken and doesn't apply where I live anyway (and hopefully it stays that way).

    OK, these guys are probably far smarter than I'll ever be, but... the universe clearly isn't staying at a finite size, and playing the universe's expansion in reverse would imply that it started at a single point. How do they account for this?

    Various Quantum Gravity theories predict different things here. Some, like Loop Quantum Gravity (LQG), predict that over extremely short distances gravity is repulsive. Applied to cosmology (Loop Quantum Cosmology, LQC) this leads to a prediction of a "bounce", where a contracting phase flips into an expansion phase.

  13. Re:Yes. on Ask Slashdot: Is Pascal Underrated? · · Score: 1

    If you got an enum, you can declare a set of that enum, for example:

    type
        TParam = (pAaa, pBbb, pCcc);
        TParams = set of TParam;

    You can then easily check for membership: if pBbb in Params then ...

    However the real power comes from being able to do set operations using + (union), - (difference), * (intersection) and the less than/greater than operators for testing for sub-/supersets, see the documentation for details.

    For example, if you want to check if neither pAaa nor pCcc is in Params, you can do

    if (Params * [pAaa, pCcc]) = [] then ...

    [] is an empty set.

  15. Re:"NAS" hard drives? on 6 Terabyte Hard Drive Round-Up: WD Red, WD Green and Seagate Enterprise 6TB · · Score: 4, Informative

    Are the Red drives designed to be paired or run in RAID arrays specifically, as opposed to the Green line that is made for power savings?

    Pretty much yes. The Red have better vibration tolerance, and the firmware is tweaked to fit a NAS workload better. For example, a Green will park the head as quickly as it can which for always-on machines can lead to a Green disk reaching its "Load/Unload Cycle" tolerance in months and die prematurely. The Red will not do this.

    There's also a difference in how they handle unreadable sectors and such errors which makes the Red play nicer with hardware RAID controllers. An unrecoverable read error in a Green can cause the whole array to go down.

    Looking over the official tutorial pages, the syntax is really different than anything I've done before. It looks hard to learn.

    Indeed. And what's with this obsession amongst the functional language developers to try to use the least amount of characters possible? We're no longer in the 1960's where verbose source code took a lot of valuable space.

    For example, when I read

    fun double n = 2 * n

    I see a function called double which implicitly takes a parameter n and returns true if n = 0, and false otherwise. Would it have killed them to separate the parameter from the "body", and used proper names? For example:

    function double(n) = 2 * n

    I've got Netflix and HBO (Nordic). Last sunday I wanted to watch the new XMen movie with my gf. Brick and mortar stores aren't open here on Sundays, so no chance there. And of course neither Netflix nor any other similar streaming service available to me carries it yet. But the pirated Bluray is out there, and it would have taken me just 15 minutes or so to download a rip and start playing it on my TV.

    No, what I think they need to do is to make a "movie-Steam" Netflix hybrid. That is, a rich catalog of movies for a monthly fee. Then allow me to pay money for early access to new releases. Once I pay I get to keep access to that movie.
