Sure, C gotos are the cleanest solution in a few specific cases and sometimes I get frustrated in higher level languages that lack it.
The HLLs that lack goto have try/throw/catch exceptions instead, which are a more elegant way to solve the same problem. Why would you ever need goto in, say, Java?
In Germany, you will be sitting at a red light, and the yellow will also come on. It is the warning that it is about to turn green.
I have seen that in several countries, in both Europe and Asia. I have also seen large countdown timers that tell you how long until the light changes. That way people can make an earlier decision to brake or "go for it" when the light is turning red, and traffic flows smoother when the light turns green, since they are ready to accelerate. I have no idea why the "yellow before green" or the countdown timers are not more common, or why neither is used in America.
Well with that the range will about catch up with my M3, but the horsepower and refuel time remain lacking.
1. A Tesla has more HP than a M3. 2. The "refueling" happens in your home, while you get on with your life, rather than waiting in line at the gas station. For long trips, you either pre-plan so that your recharges coincide with a meal at a nice restaurant, or just use your spouse's car (or maybe your mom's).
Regardless, as somebody who actually likes driving, I would still never buy one.
Exactly what type of signal would they be receiving from a postage stamp sized probe in another star system?
I don't remember the exact details since I read the proposal a while ago, and I am not an RF guy, but I think their plan was to reel out a carbon-fiber directional antenna, and then use a very high gain antenna here on Earth as a receiver. Or something like that.
Details like Facebook's headquarters are in Menlo Park, not Fremont, with the SF Bay in between?
Putting a school like this in the SF Bay Area, where there are already oddles of opportunities, isn't doing much. If he wanted to make a difference, maybe he should have opened his school in West Virginia, or the Mississippi Delta.
Indeed. The target is about a second of arc squared. There is no way to just point it in the right direction and go, but in-route adjustments are hard because of the lack of power in deep space. The students' proposal was for the "sail" to be an inflated sphere, with aluminum coating on half, and carbon black coating on the other half. It could then be rotated to steer with differential thrust. The reflective surface gives slightly more thrust than the absorbent surface. The plan was to leave solar orbit with enough accuracy to get close the target star (maybe 100 AUs) so that it could collect enough energy to power up, and then use that power to steer itself closer and closer to the target star. You would be doing this with electronics that have been in space for over a century, and hopefully your great-great grandkids are listening when the signal arrives.
We could probably do a regular-matter probe that'd get there in a hundred years, as long as it's an extremely light micro-probe which only does a flyby.
I have read proposals to do exactly that, using a probe about the size of a postage stamp, and using a 1x1 meter solar sail made of mylar. The proposal was by a group of high school students. It would launch from a Cubesat, and would cost ~$10k. The hardest part was figuring out how to steer the contraption with sufficient accuracy.
I'd wager that your preparation might need to be a little more than that.
I have prepared more than just the gloves. Specifically:
In my pockets:
wallet
cellphone (can also serve as a flashlight)
fine tip sharpie pen
on keychain:
64GB USB thumb drive w/ important documents, photos, files

Small Chomebook + charger
sewing kit (needles, thread, safety pins)
Small first aid kit
Toothbrush, toothpaste
unwaxed dental floss (a good all-purpose string)

mini roll of duct tape
LED flashlight
compass, paper map of local area
asprin
chapstick
sunscreen
vaseline

Your muscles may need a few weeks to build back up if you haven't been exercising them, but chopping wood with an axe isn't a hotbed of technological innovation.
Your hands will blister long before your muscles get sore. Get a nice pair of leather work gloves, and get them NOW. When civilization goes to shit, it will happen much faster than you think, and you won't be able to rush to Walmart and buy what you need. The shelves will already be empty. Try to be like The Little Red Hen, and plan ahead.
The original estimation for the price of an EPR at this size was 3 billion pound, now we are talking about 24,5 billion pound for the construction. The whole cost of Hinkley Point during its operation is estimated at 37 billion pound.
Hinkley Point is the "F-35 of power plants". At least with Theresa May, Britain finally has someone with enough sense to pull the plug.
The Universe has been around for 13.8 billion years.
We humans are so cute, thinking we know so much, with such certainty.
Actually, the age of the Universe is 13,820,000,003 years. We figured out that the age was 13.82B, but that was back in 2013, hence the additional 3 years.
I was surprised by the clear lack of laser beams myself.
This project started in 1958. Lasers were invented in1960. Early lasers were way too bulky to fit on a shark's head harness, and could not be immersed in saltwater.
Thousands of lightyears, sometimes even more, so we see thousands of years in the past
The Universe has been around for 13.8 billion years. A few thousand years one way or the other is insignificant. TFA isn't talking about us being a millennium ahead of other civilizations, it is about us being billions of years too early.
So similar to Star Trek, we just might get to know the club when we qualify for it (FTL Communication or Travel).....
Even on Star Trek, there are many civilizations that decline to join "the club". Star Trek is silly anyway, because it is unlikely that so many civilizations would reach nearly the exact same degree of development at exactly the same time. Also, as we learn more and more about physics, we get more and more confirmation that FTL communication/travel is fundamentally impossible. It is highly unlikely that interstellar travel will ever be like taking the train to work.
By moving the drug trade online, and away from street corners and school yards, SR was certainly reducing harm for the public, but it was also a challenge to the police state, the prison industry, and the politicians that service them. Crime in America is a fraction of what it was 25 years ago, yet we have more police, and more prison inmates than ever*. The public needs to wake up and realize what is happening. We need to vote for drug legalization, and we need to stop voting for the pro-police candidates. This November, look for the candidates that are endorsed by the police/prison-guard unions, and please vote for someone else.
*No, the prison expansion did not "cause" the decline in crime. The fall in crime was well underway before the prison buildout started. Some states expanded prisons far more than others, yet had no greater fall in crime. The fall in crime happened throughout the developed world, yet only America had a prison expansion craze.
Is it just me or does a 5 turbine wind farm sound a little underwhelming, water or not?
You misunderstand the significance. As a technical accomplishment, this is meaningless: The Europeans have been building offshore wind farms for decades. But as a political accomplishment, this is earth shattering. Despite the best efforts of all the NIMBYs and BANANAs, America is actually building something. When was the last time that happened?
The first wind turbines were installed in Denmark 25 years ago, and are still operational. So they last at least 25 years. Modern turbines are expected to last much longer, due to better materials, better design, and much greater height above the sea (100 meters for the Rhode Island turbines), which means less exposure to salt.
you'll make profit only for the last 3 years of the 20 year lifespan.
The "max 20 year lifespan" is something that Ravenshrike (the GPP) pulled out of his butt. There are offshore turbines in Denmark that already exceed that, and we have learned a lot about building offshore turbines since then. For instance, modern turbines are much bigger and installed much higher above the water than they were 25 years ago. These turbines will stand more than 100 meters above the sea. There is very little salt spray up that high. They will likely be active for much longer than 20 years.
This is a first for America, but Europeans started doing offshore wind 25 years ago. We are building on that successful experience, not starting from scratch.
it will take 16.96 years to pay that $300 million back.
That is about a 6% ROI, at a time when banks get 3.5% on 30 year mortgages. Seems like a good investment to me.
Meanwhile, in England, Theresa May just semi-canceled the Hinkley Point nuclear project because the falling price of wind energy was making new nukes uncompetitive.
I can't even wrap my head around the idea of this currency... WHY DOES THIS EXIST? EVEN IN THEORY!
Indeed. I can see how you can create these coins by participating in a DDOS, but then what can you do with it? Who is going to accept is as payment for anything?
I get very tired of apps that constantly nag for reviews.
If a company asks for a review once, I ignore it. If they ask more than once, I leave a negative review, explaining that their review request spam is a reason not to buy their product.

Then it also has to know precisely where the stop line is.
Right. Because all human drivers stop at exactly the correct spot, so automating the process would be a huge step backwards.

Might want a rooster if you want chicken and eggs in the long term.
I live in San Jose, CA, and roosters are illegal here. Too noisy.

Depends on who you are rooting for; transmission works great for the entrenched utilities
It also works great for governments trying to collect taxes.
It is much harder to tax electricity flowing between someone's roof and their kitchen.
I fail to see how videotaped 100% clear proof of violent crime can be ignored because the police break a rule when obtaining it.
Because police that are willing to "break rules" are also willing to falsify evidence and lie under oath.
