So... there are Imperial units and even banana units, but still no metric units?!? Sure, I can roughly work the specs out in my head, and call me lazy, but it would be so much nicer if one person did it once when submitting the summary.

According to this there are only three (yes, 3) countries left in the world that don't use metric units: US, Myanmar and Liberia. ie. Lots of slashdotters around the world who won't be used to imperial.

Please, could we make an unwritten rule for /. that metric units are always included? Don't need to replace the imperial values, just put the metric values in brackets.

Money shouldn't be speech. When money is speech, then those with more money get more say.

In principle I don't have a problem with that. (Personal opinion.) But in practice people are selfish, and that selfishness leads to speaking loudly for things that are not always good (in fact, usually quite bad) for those who can't pay for their speech.

Free speech ought to mean that no one is hurt for what they say. Pity that what ought to be and what is are not the same.

Ironically, that'd probably be the one turn off for motorcyclists. Imagine a group of Hells Angels taking off on silent Harley's.

When telling my martial arts students to try to practice correctly I often say:

If you practice doing something a lot, then you become good at doing it.
If you practice doing the wrong thing a lot, then you become good at doing the wrong thing.

That's where tuition is so important. A good teacher will guide students into correct technique, and identify and teach away bad habits as soon as possible.

Another thing I tell my students is:

I can teach you skills, but only you can practice them into art/mastery.

I think no, because crucial aspects intelligence include understanding and creating thinking, which none of these devices can help us with (yet?).

My father died last year, just as he was retiring. On his deathbed he told me that over the years people had said to him "Why do you spend all your money on 4WD's and gadgets? You should invest it.". But, had he done so then he would have missed out on the long camping trips with my mother, travelling overseas, doing the things he wanted. So now he could "give Death the finger", as he put it. His only regret was to have missed out on spending time with his grand children teaching them botany, entomology, etc.

Before that he'd tell me to work hard so I could enjoy my life when I retire.

The lesson he realised then was what I often say: Enjoy what you have while you have it, because nothing lasts forever.
And even if you think things are bad now, they could be worse, and might be worse in the future. Even times of suffering can be looked back upon with the positive light that comes from the distance of time and greater life wisdom (often gained from those very times of suffering).

No. The second option is the most logical, because no evidence either way is just that: no evidence

Only if we have evidence that Bigfoot does not exist, will the first option be the most logical.

That is different from what is most likely. It is still most likely that Bigfoot does not exist. (Which is why not believing in Big Foot is still a fair call.)

For example: It is suggested that Yeti might be a type of bear. Had we accepted that Yeti don't exist due to lack of evidence, then we'd never make the effort to make such a discovery. In fact, often we even reject any supposed evidence. But by accepting option 2, then the case is not closed until we have some evidence, one way or another.

Who knows what other "woo-woo" ideas might have some truth in them. I like to give the example of St Elmo's Fire. Of course angels don't dance on masts, but by at least looking into it, we found there was some truth behind the stories after all, and so we learnt something.

Disclaimer: I'm not a God believer, because there are so many easy logic traps that God simply doesn't make sense, at least not in any way I've ever heard of.

Yep. The education system even fails to teach spelling.

(Sorry, I just couldn't resist. ;)

Think of those plastic pieces in the video, but as separate pieces arranged in a lattice similar to that of fish scales. Each scale would have a hinge on top and heat would cause the scales to push themselves off the wall. Then, when they get hot, they would shade the wall, but when cool could lie flat to create a partially (leaky, I'm sure) insulating air pocket between the building wall and the scale wall.

Seems simpler, and if a few scales fail, then they could be easily tageted for replacement.

I thought it was the other way round... tough competition being the driver for cramming as many people as they can into as few flights as possible to make ends meet.

Yeah, it does seem so. Not holding my breath for it happening though. Given that airlines operate across countries they'll be able to make such decisions very difficut to get through.

If we don't know what we don't know, then we don't know if there's value in knowing whatever it is that we don't yet know. That's when we should fund research, to find out if the funding was worth the price of knowing whatever it is we don't know... and if there is something to know, whether it is worth knowing.

But if we research what we already know, then because we already know most of what we want to know about, we will know only a little more about what we know much about rather than know much more about what we know little about.

Isn't that pretty clear?

There was a guy who dreamt about being a great poet who could truly touch people's feelings. Unfortunately he lacked talent for coming up with rhyme, analogy, insight and so on.

But he found employment at Microsoft, where he finally made his dream come true as an error message writer, with classics such as "BSoD", "Press 'OK' to continue.", "Catastrophic Failure.", "Abort, Retry, Fail?" and many others that have touched a nerve on each of us over the years.
