  1. Pumps on Cloth Successfully Separates Oil From Gulf Water · · Score: 1

    Water and oil require different materials, methods and lubrication. Oil dictates one kind of pump, water another. Some water in the oil won't change the viscosity that much or necessarily wash away lubrication, but when the oil is only, say 1/20th the content of the water, you might find that systems which work well with water get clogged and systems which work well with oil seize.

    So it's a real question. I assume the answer is "You bet -- they use them all the time", but I don't know for sure. Do you? I really do want to know.

  2. Re:Use Solar Energy? on Cloth Successfully Separates Oil From Gulf Water · · Score: 1

    That would take HUGELY more energy than just about any separation process. A phase change (liquid to gas) takes a lot of energy. Better to have a solar collector generating electricity to power the centrifuge to clean the water.

  3. Re:Great for filtering, but - on Cloth Successfully Separates Oil From Gulf Water · · Score: 2, Interesting

    Actually, some sort of pumping system with this as part of a centrifuge should work well. The pipe goes into a spinning section of rigid membrane pipe. The oil gets spinning in the pipe. Water spins out, since it passes through the membrane, and oil stays in the pipe. The oil keeps going wherever it's being pumped to. This solves several problems, such as waiting for the water to slowly sink out, the cranes and manual labor involved in lifting and draining, etc.

    That is, if there are pumps that work well with oily water... There must be, right?

    Here's a very unpleasant answer:

    Shrimp, fish, squid, etc -- If they were in the oily water, they were dead anyway. They "breath" by pulling that water through gills or similar arrangements. Such surfaces will be clogged with oil and the animals will die.

    Mammals and birds have a better chance, and it seems like a skimmer like this gets them into the boat and gives rescuers a chance to wash them. They're probably better off in the boat than out of it.

    Agreed on all points. Very logical. But I suspect that there is a non-logical issue here which getting two incompatible and somewhat different (from our perspective they're completely different, but from Grandma's perspective, they're only slightly different) they'll find that they cannot control the real brand which, from a neophyte's viewpoint, is not Android or Chrome, but "Google."

    'They aren't completely separate "OS systems". They are separate brands...'

    Exactly. That's what makes it so odd. Proctor and Gamble are experts at managing competing brands, but you don't look at Tide (if you're Bob consumer, anyhow) and think "Proctor and Gamble". But I have heard Droid phone ads saying that Droid runs "Google". I think this will be an unpleasant experience for Google. We'll see.

    Thanks for the comments on how they might/will converge -- it's interesting and encouraging.

    But on a brand level, I think "Android Chrome" or "Chrome on Android" would be a much better idea than "Chrome" and "Android".

    Why isn't Google packaging a version of Android as Chrome? A restricted version of Android would work fine, and give tinkerers a path up, sell better, allow local apps which are specially judged safe for Chrome/written with tattlers to integrate it into the cloud data, etc.

    Two completely separate OS systems will cause confusion and not allow one to leverage work done on one for the other.

  20. semantics on Exam Board Deletes C and PHP From CompSci A-Levels · · Score: 1

    So this is just a question of semantics.

    I say if you've done something in a language and could recall it, you've learned it. You don't have to be good in it to have taken the time to understand what it brings to the table (at least roughly) and the complications it's designed to get around and the complications it causes. Good enough.

    You're thinking fluency/mastership.

    OK. Then it's perfectly sensible to aim for mastership in one programming language. But if you haven't done the lower level learning on other languages, you'll never have the mental tools to achieve mastery in that one language.

    It's excellent that you have a working knowledge of the minority language in your city. I know people in the US (yes, we're famous for this kind of crap) who have one language, and only one, and would insist that the people around them use only it. I married into another language, and have had the pleasure of meeting other guys in the same situation. One of which spoke not one word of his wife's native language, even though he had been married for 5+ years and had kids who spoke that language as much as they spoke English. I've met people from other ethnic groups with the same husband situation.

    "In short: monolinguism can be the result of mediocrity, but it can also be the result of a conscious aim to know one language in as much depth as possible rather than lots of languages at a basic level."

    You mean to tell me that you know good programmers -- programmers who understand who computers work, and adapt to situations, who choose the right tool for the job, who are always able to do that and yet only know ONE programming language? I agree with a number of things in your post, but really, monolinguism? Monolinguism?

    Monolinguism is ALWAYS the mark of a bad programmer. Choosing to concentrate on one may be the mark of a good programmer who is obsessive and wants to be the best in one thing, but if that programmer doesn't know (to the extent of having explored, played with, written some things to get the ideas of) more than one language, that my friend, is a bad programmer. He or she has only a hammer, and everything around him or her is a nail.

    Monolinguism takes your perfectly good argument to an extreme where it doesn't begin to stand up.

    PS. Learn a little of the second language used in your city. It'll give you an insight into how the two languages play off one another. You're getting good at communication on a simple verbal level by learning just one (sounds like a good plan) but you're missing out on the cultural aspects of a two language environment. You don't have to get good at it, but not knowing any at all cuts you off from the cultural differences which cause only 90% of the population to be bilingual.

    If you're a good programmer, programming languages are easy. If you're curious about a language, you can learn the basics of it in a few hours and be adequate in the language in a weekend.

    (Now, being good in the language requires more than that -- it requires a project or two, some refactoring and some time, but that's beyond what the poster said.)

    Even mediocre programmers can pick up the basics of any language quickly. The focus on just a core of languages, and often, just ONE language, which we often hear from job candidates and young posters on slashdot are a reflection of the many graduates coming out of CS departments these days who exhibit a distinct lack of talent. There are still some great programmers coming out of our CS programs, but there are many, many more drones than came out of such programs 20 years ago.

    Somewhere along the line, a CS degree became a way of ensuring yourself a job in much the same way a degree in accounting did, and CS began to get people who didn't really give a shit. "I'll pay the money, go to the classes, get the degree, and get a job. Then I'll be safe and happy until I die."

    Talented programmers pick up languages when needed, and they do it quickly. Programmers have curiosity about computing. Missing either of those means a bad programmer. Not knowing the basics of such a simple language as C equals a bad programmer.

    If you're bothered by that analysis, surf a little, write a few programs, read a few to see how things are done, and the point will be moot. Unless you're a bad programmer, in which case you'll find C very difficult, take weeks to get anywhere in the language, decide you need to take a class in C to learn it, never be able to figure out why your simplest C stuff won't run at all.

    And ya know what? The same goes for FORTRAN!
