Many people simply do not have that kind if liquidity, and one thing that ties up capital is buying stuff that has a freakin' 20 year payoff.

The calculation showed that you save $8,40 per year on a $25 investment, so the pay-off time is about 3 years.

Even if you have to borrow money against 8% interest to make the investment, you'd have paid down the loan in 3.5 years from the savings.

Comment Re:Kill timezones already (Score 5, Insightful) 140

Switch the entire world to UTC (and kill am/pm since they'll no longer correspond to morning/night in half the world). ... just the idea of eliminating "2pm your time or mine?" makes it worthwhile.

That might be convenient for making appointments for telephone conferences, but it really sucks if you actually travel to such a timezone and need to schedule your daily program; then you will have to calculate the offset relative to your old place every time you wonder whether it is already lunch time, or whether the shops/offices are open. Not to mention that having the date and day of the week change in the middle of the day might also be rather inconvenient: what does "see you on Wednesday" mean?

And as for appointments: calendar applications already take care of calculating the time zones while scheduling meetings.

Comment Re:We do, it's called JavaScript. (Score 1) 783

Javascript?? In order to get anything done in javascript, you need to grasp OOP, HTML, and DOM just to deal with user input/output; deal with implicit string/number conversions (which vary between browsers). Moreover to that that debugging javascript is even more horrible than in BASIC. In BASIC I could insert print statements to see what's happening. In javascript I have to resort to alert() which requires me to click OK all the time.

Eat enough legumes (the seeds/bean part) raw and there's a good chance of death.

Yes, but the topic was grains.

It's more nutritive to let a ruminant eat the grasses/grains and then eat the ruminant (not to mention the energy and input costs involved with industrial crop growing).

This is an utterly ridiculous statement. In terms of dry mass, the Feed conversion ratio of ruminants is about a factor 30 when going from grain to meat. So instead of not utilizing 1% of the grain, you throw away 97%.

Gliadin, a gluten protein and the cause of celiac disease, is an indigestible protein that ... causing inflammation, even in non-celiac individuals.

The wikipedia article on Gliadin does not state that it is indigestible, only that it is not attacked by stomach acids. From the Triticae glutens article, I get the impression that certain forms of gliadin (a small fraction of the gluten) are indigestible, but then, nutritional fiber is also indigestible, so that isn't really a problem. The article on celiac.com is written by an editor. The abstract of the original article, Gut 2007;56:889-890 doi:10.1136/gut.2006.118265 does not make strong statements about the health implications of non-CD individuals, other than " we hypothesise that the innate response is common in patients with and without CD, whereas the adaptive response is exclusive of susceptible patients with CD." (we hypothesize = not confirmed by the study)

Here's a good sumary of the trouble with eating high amounts of carbohydrates.

No scientific studies cited. I see various links to other blogs; links to FDA and the American Diabetis Association are called "our government suggests" and "mainstream opinion", as if that makes them untrustworthy. Why should I believe an arbitrary blogger's theory?

A high omega 6/3 fats ratio in the diet promotes many diseases and should be avoided.

OK, this is a scientific paper (and I didn't see it refuted from a quick google). Interesting; I din't know that there was such a difference between unsaturated fatty acids.

The pesticides, fungicides, antibiotics, colouring, preservatives, etc., present are obviously not good for you.

I could agree with you on the first three, but not on the latter two. For the colorants one could say that they don't serve a real purpose (so why take the risk), but I'd say food preservatives have made food a whole lot safer by preventing spoilage of otherwise perishable products.

"[Grains] are difficult for all to digest, have poor protein profiles, have toxic proteins, and mess with hormone balance (insulin in particular). They require complex preparation to make them non-toxic, such as soaking or cooking for extended periods. "

Can you provide pointers to scientific research that supports these statements? The only one that makes some sense is the first one, but then, most foods are difficult (for humans) to digest when raw; are you proposing to eat only fruits, milk, and raw meat?

"was immediately reverted with "didn't cite sources" " - Could you provide a link to the diff? One problem could be a lacking edit summary in combination with extensive rearranging of text. In such cases, it is difficult for an other editor to see what changed by looking at the diff. If the edit comes from an anonymous IP address and does not have an edit summary, a hurried editor could misunderstand your intentions.

I tried Dvorak on my htc Android phone, but I didn't feel that it served much of a purpose when not touch typing. But more importantly, there was no text prediction nor support for long-press special characters like in the native htc keyboard.

No, it's the work done by the prop that heats up the air. Any heating up near the walls is balanced by cooling down elsewhere in the tunnel. The interesting thing about friction heat in a gas pipe is that a temperature increase causes the gas to expand, which costs exactly the same amount of energy as you put in. The net effect is that the gas expands along the pipe without a net increase in temperature.

Comment Re:1,382 degrees F (Score 1) 132

Would layering this stuff between air gaps suck in more heat than you lose in temperatures that cold?

Unfortunately not; such a hypothetical material would allow you to create a temperature difference out of nothing. The best way to limit radiative heat transfer is by having two reflective surfaces, such as aluminum foil. In addition to that, you need to prevent heat transfer due to air convection. That's why thermostat flasks are vacuum and shiny on the inside.

Comment Re:What kind of problems does it create for pilots (Score 1) 379

I believe that the risks are a bit exaggerated. Yes, the laser beam is quite bright, even at long distances, but at a kilometer, the spot is about a meter in diameter for a laser with a cheap lens. At 1 mW power, that is about 100 nanowatt entering the eye, an amount similar to looking at the laser spot on a white surface from half a meter distance. Hardly something that will blind you, even at night.

Moreover, keeping the spot steady on a target, moving or not, is impossible with a hand-held laser. That will reduce the time-averaged power by another factor 20 or so.

I have pointed class-2 laser pointers at my own eyes plenty of times, half a second at a time. Both green and red lasers. It's really no big deal. Class 2 is, by definition, not harmful for exposures less than 0.25 seconds.

That said, I can understand that they don't want people to point lasers at planes. It's a matter of time before someone does it with a tripod-mounted class 3a laser (or even a 500 mW class 3b laser as was featured on /. a few months ago), in green or blue color (more blinding effect for a dark-adapted eye), which is definitely dangerous. This way, they raise public awareness that intentionally trying to hinder aircraft pilots, succesful or not, is unacceptable.
