I agree with everything you said. As I said, provided the elderly are warned there will be no one whose life would depend on their money because its a private school and so on, the problem would be similar to the elderly's grand children asking money behind their parents backs.

Well I haven't read the article, but have a few comments to make:
  • CNA is a private english school, as such they are not exactly cheap. So, save a really bad apple, nobody there should be in need of money. Provided this is discussed with the elderly, this shouldn't be an issue. Not a greater one than the elderly's grand children asking money to their grandparents behind their parents backs.
  • It is stated that the conversations are recorded and evaluated by teachers. That would also work for avoiding most of the cases.

Comment Re:biofuels (Score 1) 256

Any citation on this? From what I remember they were always flex, even if sometimes you might have to manually adjust something.

Since you quoted wikipedia, there it goes: ethanol fuel in Brazil. To get the info in a glimpse, check for the caption on the first image of the section (the FIAT 147 one), and read on for further info.

But I know where your misconception comes from: only recently pure ethanol has been used. It was used both as solute and as solvent to gasoline. As a solute, up to 25% volume, it was used to reduce gasoline dependency; and as a solvent to gasoline it was used to help deal with cold start problems of the ethanol prior to electronic injection, but cars were classified as ethanol fueled or gasoline fueled, nevertheless.

Since the 1970's, cars have been run on ethanol; but until recently (post 2000 or so), you had to choose either gasoline or ethanol and buy a car based on this choice. Nowaday most (if not all) new cars produced there are capable of using both in any proportion. And where would the biodiesel come from? Algae for fuel is something I hadn't heard before, I'll look into it. One promissing source of fuel is the digestion of celulose, this is what I'm hoping for.

All it takes is the first commercial project producing bio-fuel to start making money, then development work will drop the price of biofuel even as the cost of extracting fossil fuel will continue to rise.

Did you know that since the 1970's around half the cars in Brazil are fueled by ethanol produced from sugar cane? You would think that a demonstration this wide was convincing enough, but here we are still gargling oil.

Comment Tor site says so (Score 2) 234

To make a long story short, Tor warns about this in the site, if not with the exact words, anyone capable of watching outgoing traffic from a machine and incoming traffic to the destination server may be able to match both. Thinking that most internet traffic goes through the US, it not really a surprise they are able to do so. Saying they will *never* be able to de-anonymize all Tor users to me sounds like a trap, an attempt to make users feel safe, but instead might just be a computational power issue.

Given all of that, if advertisements are unavoidable I'd prefer random advertisements that are totally untargeted to who I am and what I do. I know, I know, that is "unprofitable" for the service providers and merchants.

You really woud rather have a penis enlargement ad, nsfw banner or pyramid scheme ad instead of whatever it is you get? You know that no matter how good the offer they're showing you are not required to click, or spend money, on it, don't you?

In any problem, if you find yourself doing an infinite amount of work, the answer may be obtained by inspection.
