  1. Re:I make beer... on The Fascinating Science Behind Beer Foam · · Score: 1

    Actually cans don't foam much. Many soda formulations include anti-foaming agents specifically to avoid the problem. So 3 is not so trivially false.

    Also there are a number of other possibilities your list excluded. The most obvious being "the time that elapsing during the can transfer and top-taping are sufficient to squelch the foaming reaction; a can sitting untouched for the same period would also not foam".

    And if you do have children you almost certainly lack perspective just as badly as those without children.

  3. And in "real-life"... on Most Parents Allow Unsupervised Internet Access To Children At Age 8 · · Score: 3, Insightful

    And in "real life" 100% of parents allow 8-year-olds to have unsupervised in-person social interaction with their peers (and probably on the phone as well). The fact that socialization is happening with the aid of a computer does not make it inherently more dangerous; without the Interwebs this girl would still have been harassed, and we should be working to stop the harassment, not to stop the use of computers in harassment.

  4. Re:This is discriminating on Finland's Algorithm-Driven Public Bus · · Score: 1

    I'm not sure what you read that said the system wouldn't allow access from any IP-capable device or even by phone. Most bus systems already provide telephone access to dispatchers (for services much like this) and there's no reason to think this service would be excluded from that existing interface.

  5. Re:How do we get Congress to sign up? on Buried In the Healthcare.gov Source: "No Expectation of Privacy" · · Score: 1

    You can self-insure for medical insurance in most states as well. Self-inusrance is nothing new and the ACA doesn't change its availability. Contact your state's insurance commissioner for details. (And stop posting misinformation once you've done the research).

    I'd also be happy to give you a waiver if you agree never to use any of the public health services that would otherwise be available. Exactly how you'll guarantee that you'll never be injured or stricken ill (or that when you are you'll only accept care from non-publicly-funded facilities and services) is a bit beyond me, but if you can work that out I'll write my congress critters and ask them to remove you from the individual mandate post haste.

  6. Re:Whatever happened to on Linux RNG May Be Insecure After All · · Score: 1

    Without whitening you're likely to get biased output, which is undesirable in most of the contexts where you'd want a truly random number in the first place. You can do whitening in software, which is fine for things like seeding a PRNG where you've already got a lot of code related to managing incoming entropy, but it makes the instruction difficult to use in other contexts where you just want a random number for direct consumption. On the other hand, pre-whitened data is just as useful for PRNG seeds *and* can be consumed directly. Arguably they should *also* provide access to the raw stream so you can do your own whitening (or not, if your use doesn't require it) but if they're only going to add one instruction it's easy to see why they chose the whitened version.

  7. Re:Vehicle next door. on Ford Showcases Self-Parking Car Technology · · Score: 1

    So long as all of the drivers doors are on the same side that's not really a problem -- this system still lets you reduce the amount of slack space between parked cars by 50% because you only need room for doors to open on one side rather than both. In the case where both cars support auto-parking you can further reduce the amount of space required, but that's just icing on the cake.

  8. Re:Dumber and dumber on Ford Showcases Self-Parking Car Technology · · Score: 5, Insightful

    While I agree that more driver skill is generally desirable it's a question of balance -- there are all sorts of potentially useful driving skills that we don't even teach let alone require for the typical driver, instead relying on vehicle, roadway, and traffic engineering to provide the desired outcomes. We try pretty hard to design public roads to not require complex or tight maneuvering specifically because many drivers lack those skills (and more generally because it improves safety even among drivers who have those skills, as accidents *do* happen even among highly skilled drivers).

    I also object to the idea that there's an externally-relevant distinction between a driver using technology in place of manual skill. We only really care about the effective skill of the combined vehicle-driver system; I couldn't care less if a bus doesn't crush me because the driver has super-human skills or because the computer stopped on behalf of a sub-par driver -- in both cases I avoided potential injury. If you want recognition for your driving skills enter a race; the rest of us only care that your vehicle doesn't do something harmful.

  10. Re:Sounds great! on Car Dealers vs the Web: GM Shifts Toward Online Purchasing · · Score: 2

    I wouldn't define any business that acts as a legally-protected middleman as "successful" -- actually successful business provide their own value and don't need legal protections because customers are happy to pay them for that value.

  11. Re:This is a GOOD thing on Car Dealers vs the Web: GM Shifts Toward Online Purchasing · · Score: 1

    GM currently doesn't do same-day delivery, but that's not a limitation of a central sales model -- they could easily stock cars in warehouses around the country ready for immediate delivery if they thought the sale advantage was worth the overhead.

    It's definitely better. Though if the banks were even marginally more willing to subscribe to a standard for data exchange it could be 1000 times better. For example, the current system does not allow the retailer to ensure that the same transaction type they requested was actually used in the approved transaction.

    If you made those same sort of generalizations about anything other than age we'd call you a bigot, and we'd be right. It's *always* unjust to apply population statistics when making a decision about an individual. Even if the statistics are relevant to the topic at hand and not themselves biased by their construction or measure (both of which are often false) they still don't tell us anything about the person in question and should not be used to make judgements about that person.

    I don't understand why there's a story about a video device including a 2-port HDMI switch. Your TV probably has a much larger one already, and if it doesn't you can buy one for like $9 from Monoprice. How is this news?

  16. Re:Nobody is Banning Tesla on How Car Dealership Lobbyists Successfully Banned Tesla Motors From Texas · · Score: 5, Insightful

    If it's "dishonest" to frame this as "Tesla can't sell cars in Texas" then it's equally "dishonest" to frame it as "Tesla can sell cars in Texas if the follow 'the rules'". Both of those statements are true. Neither tells the whole story. And there's no reason whatever to accept one version over the other.

    In 1960 blacks it was true to say "blacks in MS can vote if they follow 'the rules'". Of course "the rules" were desperately unfair both in conception and enforcement so in practice kept blacks from voting. Hence it was also true to say "blacks in MS are not allowed to vote". Just like in the Tesla case neither simplistic statement tells the whole story, but neither is any more "dishonest" than the other, they're just framed from different points of view.

  17. Re:Sounds like John Gilmore has called it accurate on John Gilmore Analyzes NSA Obstruction of Crypto In IPSEC · · Score: 1

    Depends on whether your bottleneck is the network or the CPU. If you've got more than about 100 MB/sec between the hosts (and don't have hardware-accelerated encryption) the crypto speed could be a limiting factor. But for most over-the-Internet applications the network tops out well before the CPU.

    No, we're not. Modern concrete is available with a whole slew of engineering properties, including the ones citied in that article. But for most projects those properties are not nearly as desirable as they are made out to be in the article, and they're definitely not worth the additional cost. Besides that, there's not enough fly ash in the world to make EMC for all the concrete we use. There's probably enough volcanic ash for a while, but something tells me that shipping off half of Mt. St. Helens would upset people.
