That probably won’t work. Vitamine D production is stimulated by UVB wavelengths (270nm to 300nm). These wavelengths of light are very heavily attenuated by fiber optics (because of scattering in the fibers). Sorry.

At a Christmas party about 12 years ago I ran into a woman that I had been on a couple of dates with. Because she and a her girlfriend at the party were drinking I offered to drive them home. On the way home her girlfriend got a call, learn

I generally keep my eyes open for climate change news and didn't see this. Do you have any reasonable references that explain that ClimateGate was a smear campaign? I thought it was a small number of committed researchers making some m

Envy, boredom, anger, signaling to others or showing off were good enough reasons for vandalism amongst many of the kids I went to school with. Financial gain wasn't a requirement for them to be destructive.

First, keep solving problems. Mathematical brainteasers got me started problem solving when I was in grade school. I really like Martin Gardner's books[1] and those by Robert Smullyan[2]. These kinds of problems develop the flexibility

Although a recent Scientific American article had a few quotes suggesting wind and solar being complementary [1], these seemed more anecdotal than persuasive. Other studies do indicate that they are complementary, but don't seem to app

Yes, and I think something else has happened to flying as well. Computer modeling has gotten so much better. I have flown a lot over the years (just under 2 million miles on American alone), and I notice a huge difference between the number

I like to drive around thinking about what it is like to be a driving (human) computer. Every time I touch the brake because I see a kid standing a few feet from the curb and a small dog on the other side of the street is running, I wonder

Mercury delay lines were a form of memory that predates and is distinct from plated wire memory. Plated wire memory is magnet memory, like core memory, but with permalloy coated wires rather than little permalloy donuts like the elements of

I've read a great deal for the last 50 years, but I feel that this gives me little time for fiction. Every time I pick up a fictional work, I know that I'm going to be forgoing hours of reading or thinking about other things. I fe

I don't think criminals are wise, but protection from police bullets doesn't seem like a reasonable motivation to wear bulletproof clothing. If required, the Police will simply call out a SWAT team using military weapons. There sh

I was somewhat involved with CORBA in its early days. It had some very smart people driving it. It was derived from work already being done by the large companies like IBM, DEC, Apollo, Sun, HP, and Microsoft. But CORBA was haunted by a key

I grew up in an inner city Detroit neighborhood. The junior high school that I attended was pretty rough so, to avoid the gangs that formed after school, I quickly ran over to the near by public library and stayed there until it was safe to

Written in 1943! This really resonates with me. One reason I like working in software is that many of the limitations of other engineering disciplines (the strength of materials, the weight of concrete, etc) don’t limit our creations. Our

Brown, green, hazel eye colors are variations in the amount on melanin in the iris. This amount can change as one gets older. Babies can have lighter eyes that become darker. Blue eyes are believed to be caused by an isolated, inherited gen

But I like the simplicity of the design, the poster’s first hand experience, mentioning other designs, and the idea of leaving usable room underneath the laptop. Further, it’s nicely illustrated with a photo. Not, perhaps, a mathematical to

Basically, programming language paradigms evolve and new languages are developed. Smalltalk was influential, but new languages have moved in and taken over the space where Smalltalk might have been used otherwise. I saw Smalltalk running on

I don't believe that lucidguppy was saying that your system was an experiment. Instead, it would be interesting to try implementing your system in a second language so you could compare and contrast the differences. (Of course, in the

Not the same thing but fascinating, in a similar way, nevertheless are the ant super-colonies that stretch thousands of miles! See: http://news.bbc.co.uk/earth/hi/earth_news/newsid_8127000/812...

No information can travel more than a foot (11.8 inches) in a nanosecond. Grace Hopper used to give a talk where she held up a piece of wire that was that long to illustrate this limitation. [1] The first Cray computers were designed in a c

I've always thought that if we are redefining time units a better solution might be 100000 metric seconds in a day (making them a bit shorter than the existing 86400 in a day) and otherwise the same relationships you've suggested:

Should first class seating on airplanes be eliminated? Should seats to sporting events all cost the same? Should all of us drive the same model car or should all models just be priced the same? Should steak be priced the same as hamburger?

This $40 was a charge that allowed willing, solo drivers to use the car pool lanes. No one had to pay the $40; they could continue to drive solo in the non car pool lanes as they had previously. This option was just added.

I don’t think people are saying compilation doesn’t matter. Certainly, I would consider C++ to be a language that is at the high performance end of the spectrum. High performance languages, high level languages like C++, Rust, Ada, Haskell,
