We had servers with dual power supplies that were hot swappable. If the equipment is online 24/7, it should be designed for that purpose. If the organization doesn't spend the extra money to get this redundancy and reliability, then expect to get what you paid for.

If so, then why is the Arduino so popular? Once the program er, the sketch is done, like the Arduino, it doesn't have to be connected to anything other than the device it controls, which might just be relays or optoisolators. Bingo! You have your multi colored Xmas tree LED light controller, or model railroad crossing, etc...
But leaving the flowers and traveling down the twigs to the branches and then down to the trunk, it all gets more generalized, until... until... no one really knows!
One could say statistics, but that is just another branch of mathematics, as is double entry bookkeeping.
One could say the lever, but it and the wheel are just another form of mechanical engineering.
One could say the astrolabe but it and sextants and telescopes are just an improvement in astronomy.
And so forth. I think the greatest contribution to mankind in the 20th century is penicillin or antibiotics, which has saved millions of people. But that is just a flower on the tree. And then I wonder, with 7 plus billion people on this planet, if that was such a good idea after all. :-/

There is no disagreement with climatologists. However these documents also have inputs from governments.

It's shocking that so few have been able, with help from the media, to influence so many people on such an important subject.
Re: Future mineral reserve creation
I was looking through comments trying to find when someone was going to bring this up. Those rarer minerals aren't going to disappear (unless they get launched into space), so why not just recycle them? Like they're now doing with lithium batteries. We get hit with a core charge if we don't return the dead car battery that we just had replaced. Much of the copper gets recycled. Same with other metals. This was not even addressed in the article - it should be.
Re: Imminent Extinction
Indians already have an extinction problem. They hold cattle sacred and cattle die in the street. They drag the carcass out to a field to let the predators have them. But the predators like vultures are dying off, so now they have a rotting field of cattle carcasses spreading disease and not being recycled by nature. I think they might have to start changing their ways and treat cattle as food.
Re: Light, camera, wait - what about the light?
3e9 / 93e6 equals 32.something. The inverse square is 1/1040 the light of the earth's, but Pluto has no atmosphere to block out all the UV and IR, etc. Knowing how bright old Sol is here, it doesn't seem like Pluto is dimly lit. How many f stops is 1/1000?
The Nightly Business Report did a story on the problem the states are having: the wealthy are taking so much money away from the rest that there is less commerce, and less revenue from taxes, etc. Those companies like Apple, with nearly a trillion dollars taken away from consumers, seem to be most of the problem. The economists call one form of this stuff rent seeking.
Re: Retail bankruptcies are never fun
All those brick and mortar stores released onto the market are going to be leased by Amazon, so they can fly those limited distance delivery drones from a mini warehouse nearby to your front porch. That is, if they can get the FAA to approve their drone delivery system..
Re: Another one bites the dust...
Long ago, Tandy bought Radio Shaft and they also had Tandy Leather stores in bigger cities. Anyone could buy an unfinished leather belt and with a few tools make it into a nice custom present for one's kid's birthday. But Do it yourself stuff, just like Heathkit, just couldn't compete with cheap imports.
But they do have a choice, to do what Blockbuster did - close the stores and sell online.
Re: Another one bites the dust...
Same here. Years ago I went into a store for some parts. I stood behind a guy who was waiting for the salesdroid to finish activating some other person's cell phone. After ten minutes, the guy ahead of me got fed up, dumped the items on the counter and walked out in a huff. I was kind enough to go back to the shelves and put mine back on the pegs, then I walked out. After that I didn't go into another RS store for years.
I did go in recently to buy a battery holder. Then I recently went into a RS store and walked out when I saw they wanted $20 to $25 for a USB cable. I walked across the parking lot to the dollar store and bought one.. for a dollar.
I have no sympathy for them, because they once served the customer, but now have lost that service. I think if they drastically cut the number of stores - there are far too many in the metro area where I live - then they might survive. If they liquidate, I don't think I would go out of my way to buy stuff marked down 80 percent, because it would still be overpriced.
Re: Good Riddens (sic)
Riddance, I I R C.
Yeah. In a very somber ceremony, line 'em up against the wall and shoot 'em - with blanks. See how much fear and sweat they have; see if they need a change of underwear. Maybe he'll think twice when they tell him that next time the victims get to choose the type of bullet - real or blank.
Re: @Jonny Canuck
What I have a problem with is that the (TLA or three-letter acronym) has no problem with kidnappings a real person, but they are seemingly unwilling to do the same thing virtually. I've always heard the warning that it would be 'violating the law.'
In other words why don't those TLAs use offense as 'the best form of defense' instead of kidnapping someone? Instead, just kidnap his botnet, or something similar and just as underhanded as kidnapping. Or am I unaware that it's already being done, but just secretly...
Re: One of these things is not the same as the other...
The thought occurred to me that we are observing a small fraction of a milliradian(?) of the light coming from the SN. Suppose it took 7.7 hours for the light to find a clear path through the debris from the SN, but the neutrinos weren't hampered at all by the debris. Simple explanation, no?
Re: The closely circling black holes are in a galaxy more than four billion light years away
What's amazing is that we're looking at black holes that were happening about the time the earth was formed. Everything about them should be said in the past tense. If we were there at the present time, they may have already died and something else may have taken their place.
"In a galaxy long, long ago and etc."
I don't believe the word selfie was in common usage when it landed. But it did take a picture of itself with the robotic arm when it landed, pieced together from several individual photos. You must be named Thomas.
Doubting Thomas. And obviously not a 'boffin.'
The 'other country' that may make it to Mars should first do as we in the U.S. did, put a man on the moon. Once the future generation of boffins understands the extreme challenges of space travel only 240k miles away, then they can proceed to a much more distant planet.
Re: What's the problem?
What really bugs me is this. I bought an item on Amazon. Now most web pages come up with an ad trying to sell me the same item! How useless can they get? I already have what I wanted! Seems like the advertisers are making money off the retailers by selling them worthless data! The customer ultimately ends up paying for it.
Re: What's the problem?
I think a much, much better way of saying it is that Common sense isn't very common.
I think the statistics gurus would laugh! After all, the statistics would just make accommodation if everyone 'got stupid'. We would then have the smartest stupid person, IQ 40, and the stupidest, 20 (barely able to put his pants on) and somewhere in the middle would be "normal". How does it feel being included into a group with a bunch of chimps?!
Re: If you could buy elections Ross Perot would have won
It levels the playing field. It fights fire with fire by using the same method that the rich use to tilt things in their favor. But it would make more sense if the unions were doing it; this still has a bunch of rich people calling the shots. Just remember that we (U.S.) have the best government that money can buy.
Re: "equivalent to
I disagree about the random movement. You see, we Southern Californians know about Wrightwood. It lies directly over the San Andreas Fault which periodically has very random movements! We have many earthquakes everyday, most of them being less than 3 magnitude which no one even feels. But I'm sure it affects the laser beam. I just wonder why they chose such a seismically active area for the equipment.
Not as accurate as..
I think the news helicopters have this one beat. They have a camera with a super long zoom lens that has to cope with vibrations in 3 dimensions, yet can zoom in from 500 meters altitude and lock on to a nearly vibrationless view of a person on the ground and easily tell if he's holding a pistol or a microphone. And they don't have any laser beam to guide them.
