top Ask Slashdot: Where Do You Stand on Daylight Saving Time?
The daylight to dark ratio is approximately constant only in the tropics. There is gets light about 6am and dark about 6pm year round and with almost no twilight between the two. The further north you go the greater the difference between daylight and dark hours becomes until you reach the arctic circle (I left out the southern hemisphere intentionally -- there is very little land at the higher southern latitudes) where there is about 6 months of daylight and six of darkness. The whole thing about DST is so artificial anyway. Until the rail roads set up standard time zones in the US each town and village had its on time based on local noon by the sun.
However, I know that in my case sunlight in my bedroom window makes me wake up more easily and feel more refreshed than being awakened in darkness. This seems to be at least somewhat invariant as to the actual number of hours of sleep I got within limits. Since I inhabit the temperate zone in the Northern hemisphere I would much prefer to just hibernate through the 3 to 6 months of winter (depending on latitude) we have here and not worry about changing from DST and back.

top Liking Analog Meters Doesn't Make You a Luddite (Video)
If you have ever done anything like aligning RF circuits or devices you are often looking for a peak or minimum value as you make an adjustment (or several interacting adjustments). An analog display is about the only thing that really works for this. THIS can be simulated on a digital display IFF it is fast enough to follow the changes AND if the digital circuits are shielded well enough so they are not fried by high RF levels or conversely inject enough RF crap into what you are trying to adjust to make adjustment impossible.

top Robotic Taster Will Judge 'Real Thai Food'
Point Taken, and I do love independent non-chain eateries. Everything has become too generic and "safe" anyway.
Yes, I know that everything has changed in 40+ years. I was there in 1971 and 1972 and it was a different world and a different place then. Also I was aware even then that the foods used and preparation varied widely around the country. Where I was was right on the border with Laos and there was much overlap between the Thai and Laotian foods. Even the ubiquitous Khao Phat fried rice varies widely around the country.
I did eat as much of the local food where I was as my taste buds, and system could handle and only got amoebic dysentery once, and that was from some ice in a drink I think. By the way, eating the local food was one of the LEAST risky things I was involved in while I was there.
top Robotic Taster Will Judge 'Real Thai Food'
I lived in North Eastern Thailand for a year decades ago and had some wonderful food while I was there, but it was almost never EXACTLY what the Thais in the area ate. Most westerners could not, or would not, eat the "REAL" Thai food. It wasn't just the spices, although they were far too hot for most people. The types of food and the way they were stored and prepared was just an entirely different culture and what is and is not food is to some extent determined by culture.
I saw a giant Mekong catfish lay on the side of the road for at least three or four days before it was considered "ripe" enough to use in food. When I was there refrigeration was rare and most food sat out in heat and humidity for extended periods. The climate was even a bit more that I was used to -- and I was born and raised in the deep south before air conditioning was common. The aroma of a Thai open air market is to say the least unique. Thailand is one of the most beautiful places I have ever seen, and the people are the friendliest and most open anywhere, but eating "real" Thai food is something I was never able to really appreciate.
There are places I have eaten in the US that have excellent Thai food, but it is not what you find the Thai's eating in Thailand. Maybe Anthony Bourdain can eat real Thai food, but on a recent episode of his show it appeared that even he was having a bit of trouble with some of it.

top Utilities Should Worry; Rooftop Solar Could Soon Cut Their Profit
In Georgia both the PSC and the legislature is being lobbied hard to effectively outlaw private solar installations at the same time that the utilities are running a PR Blitz about how much they are working on solar energy.

top Bioethicist At National Institutes of Health: "Why I Hope To Die At 75"
I watched both of my parents succumb due to Alzheimer's and if you have seen that disease up close and personal like I have you really don't want to go there. I really didn't expect to live as long as I have. That may be something common among those of us that grew up in the "duck and cover" generation and then took that year in South East Asia back during that unpleasantness. There is a song by Jimmy Buffett that sort of says it all to me -- the title is
Pacing The Cage.

top My degree of colorblindness:
I have been doing electronics since I was about 10 years old ( I am now 67 ) I don't think my eyes have changed as much as the colors used on some of the imported components. I have some old new stock AB resistors that are just as sharp and clear as to which color is which since the day they were made. For some recent purchases of bulk resistors I have had to use a good lens and a halogen light to even read some of the colors and often would resort to a ohm meter to be sure.
Only exception to this was when I was about 15 and read the third band of a two watt composition resistor as brown. Well, it had been a bit toasted and was really violet. The replacement didn't last but a few milliseconds when I applied power.

top Bad "Buss Duct" Causes Week-long Closure of 5,000 Employee Federal Complex
Not too surprising. I worked in a building in Atlanta where the UPS's in the computer room kept tripping for no apparent reason and kept reporting wiring faults. We had half a dozen electrical inspectors and electricians in to try to find out why and none could. I brought in a volt meter from home and checked the outlets. The "ground" from the sub-panel in the room was at +50 volts relative to the return neutral side of the line. The sub-panel had been connected to a transformer in the main electrical room on the floor that was not wired correctly. We had to shut down the computer room for two or three days while they replaced the transformer -- and then they wanted to charge us for it!

But are not roads and highways also subsidized with taxes. In fact there is talk now of increasing the tax on gasoline since it is not enough to keep the highway trust fund solvent. I don't know about current subsidies, but when the first railroads were built they were subsidized with large land grants to the companies building them. The notion that "the market" is always right and should decide whether anything is done and what the price for it should be is only true for those areas in which it is applicable. There are many things that can not support a market, that are still desirable for society as a whole. In order for things like roads and highways to exist there must be some form of subsidies. Whether they are direct or in the form of "membership cooperatives" (e.g. Electric Membership Corporations) they would never exist if left to private enterprise alone.

top Siphons Work Due To Gravity, Not Atmospheric Pressure: Now With Peer Review
I actually had a problem like this on a final exam in Fluid Mechanics back in the late 1960's. The required answer was the flow rate through the siphon for which there is an equation that uses parameters such as the pipe diameter and the difference in elevation between the inlet and outlet and some other things. However, the problem was given in such a way that it was not at all obvious that the siphon (which was a water siphon on Earth) at one point exceeded more than 33 feet above the inlet point. If you READ the entire problem carefully and CHECKED for this NECESSARY condition you had the answer (zero flow rate) with NO calculations needed -- a real time saver on the slide rule!
