Comment Re:Self learning classroom learning (Score 2) 102

People would set up "learn farming" systems similar to today's "perk farming" systems, to make it look like they're watching TED talks and reading technical articles on half a dozen devices at once all day long.

What's the difference? Watching a TED talk or reading a technical article doesn't imply that any understanding, retention, or learning has occurred between the ears of the content consumer.

You might be surprised how helpful it would be to know the most recent area a person stayed, to remind them before their visa expires what their options are, and to know within a month that a person that should have checked out of the country did not do so.

You are correct - I would be surprised. The most recent area is pointless in a country where you can catch a bus or train from one side to another in a few days. Reminding them their visa is about to expire can be done using the email address/contact details that all US visitors have to provide when they get their ESTA or visa in order to be allowed entry to the country. Knowing to the day that a person that should have checked out of the country and did not do so is already recorded trivially at passport control. None of these tasks require the multimillion dollar cost of setting up and manning checkpoint offices across the country.

Your assumption about ankle bracelets is quite ridiculous. If you want to get modded informative, don't make shit up that isn't reasonable. I understand you don't like Christie, I'm not a big fan but at least I don't have to resort to hyperbole to justify my opinions.

On the contrary, my opinion is that ankle bracelets are pretty much the only reasonable way to make a scheme like this work. The self-driven check-in option you've proposed is just a huge waste of money with no useful outcomes (as I said before - probably just a boondoggle to enrich Christie's campaign donors). I don't follow US politics closely enough to like or dislike Christie or even know who he is, as my country has enough political problems to fill my news feed. I'm just pointing this particular idea out for the BS that it is.

And where specifically did you read that people will be tagged with an RFID? They could simply carry an ID card. A perfectly reasonable requirement. They could check in once in a while. Another perfectly reasonable requirement. Many here are making up unreasonable scenarios then arguing how stupid they are.

Of course. A visa over stayer will definitely check in once in a while - they didn't mean to over stay, and of course they will go to the check in point as legally required. A perfectly reasonable requirement which will have absolutely zero effect since the only people who check in are the people who are law abiding and were going to leave on time anyway. But it will create jobs for all the people needed to man the check points, Chris Christie's mates will get nice fat contracts to run the whole shebang, therefore the economy will be stimulated, and the only people that will be worse off will be legal immigrants and american taxpayers.

The only way to do this in a manner which will actually catch illegals is to tag all immigrants with an ankle bracelet or similar when they arrive - hence my initial comment. Christie's suggestion is less than a thought bubble, it is so lacking in content that it should never have been spoken.

Yet here you are defending the idea, and modded informative non the less. Maybe people do get the government they deserve.

I can see it now. Ivy league university hires world class researcher, who has to get tagged with an RFID as if they were cattle to be allowed to work in the US.

Similar for other professions: medical, engineering, etc.

This will work so well. Christie and his entourage must be completely incapable of critical thought to consider this idea for more that 10 seconds. A proposal like this would destroy the ability of the US to maintain world class leadership of anything.

Comment Re:Go Solar, it can make good financial sense. (Score 2) 259

I'm always astonished at the high price of solar power in the USA. Here in Perth, Australia a 5KW system can be had (fully installed, no rebates or other breaks needed) for $5k AU (which is under $4k US). You can get a German (Bosch) 4.4KW system in the $7k AUD range.

Why is is so expensive in the USA?

Can you provide a link to a vendor's website that has those prices? Even with shipping that would be a good deal for us US-aliens


Comment Re:One such stamp will pay for *all* the research (Score 1) 43

Any such stamp that can detect blood glucose reliably would pay for all the research: blood sugar.

Unfortunately, this technology measures chemicals from perspiration, and sugar levels in sweat or saliva change much more slowly than they do in blood. So by the time these stamps measure a sugar level spike, the person will likely already be in a diabetic coma.

Blood will be the only option for the foreseeable future.

Human waste contains heaps of harmful bacteria.

Poo? Yes. Piss? No.

Your kidneys filter at the molecular level and thus are VERY good at preventing bacteria from entering your bladder...

You should RTFA: The device is for extracting water from feces. That's poo, not piss, and in the context of the article, obviously what I was talking about.

Bill Gates didn't invent it, and he isn't trying to sell it to you either... He's trying to promote it as a means of helping people who have difficulty accessing potable water.

My point was that Bill Gates shouldn't be endorsing it based on the fact that he personally "studied the engineering". He simply isn't qualified to make a call like that. No point selling it to anyone if the water output becomes poisonous over time.

Water's water - given the diffusion time we're probably all drinking King Tut's piss today (not to mention plenty of other peoples/animals).

While that is true, my problem with the story is this bit:

And having studied the engineering behind it, I would happily drink it every day. It's that safe.

Bill Gates studied the engineering behind it? I am so reassured...

Human waste contains heaps of harmful bacteria. If I am going to drink water recycled in this manner, I'd prefer to have the engineering studied by an independant water quality professional, say, an environmental engineer? And for the output water to be studied by health professionals and microbiologists. Some long term testing on how well the product holds up as the filters degrade would be nice too. That first glass may be clean and delicious, what about the the tenth, hundredth, or thousandth glass?

The recommendation of the former CEO of a software corporation (no matter how successful) doesn't really give me that high a level of confidence in the product.

The trouble with doing something right the first time is that nobody appreciates how difficult it was.
