My guess is EPA, where it's much less. Also, 700 kids is an entire K-8 school in the Redwood City district, the annual operating costs of an entire school including construction, teachers, supplies and administrators is millions.
I'm in the Bay Area, and we're talking about parents hiring aids for our teachers because the student to teacher ratio is 30:1. Any relief from the local communities is welcome. All of the weird projects California funds without funding art, physical education, and music in the local schools really shows how skewed the priorities are.
I'm having a hard time seeing the negatives. This is a prototype to try new educational ideas, but really what they are doing is helping the local community. Odds are good it's East Palo Alto (EPA) that will be most served, Palo Alto schools are quite good. The EPA schools are rated low, and any family brought into it will be getting more than they could get from public schools.
And if underprivileged children should have project-based learning that adapts to their learning capabilities, is that really so dystopian? They are trying something new, and offering it to those who wouldn't normally have the opportunity.
Hard to tell, but the estimates that I've read for the train are 6 million people annually travel the LA/SF corridor, which for this 68 billion dollar project amounts to about $100 per person per year for 10 years in capital expenses alone. However, as there is no way all six million could take the train (365 days a year, assume 10 trains daily both ways, 3,650 trips, assume 500 capacity per trip, 1.85 million people at 100% capacity, which won't happen)...I don't see who we are helping here because the ticket costs would exceed the comparable airline costs.
Except the clear evidence really isn't that clear, there are differences between men and women in the UK of 3 to 1.5 per 100,000 people, and thyroid cancer is up to 15 per 100,000, the peak of your referenced graph, (with an increasing trend) in the US. As the US was further away from Chernobyl, does that mean it helped people prevent thyroid cancer?
I'm not sure what the reasonable course of action is, but giving money to everyone isn't it.
For linear attenuation of sound, Stoke's Law is more appropriate for a back of the envelope estimate. More searching will yield more refined models. That being said, no planar transducer propagates only linearly, and there is decay in the x and y directions (considering z as the normal vector).
I was scratching my head when I read about this idea because I work with ultrasonics a bit and we have a heck of a time with maintaining energy density over short distances.
A lot of the code I worked on wasn't source controlled, and that was what I was thinking about with this note. Still, most source control systems are time-stamped with the user who made the change, and usually have a comment section for the changes. If you make a change to code, you should change the comments too, and also see a history of the changes. Sometimes the problem changes, sometimes the solution changes, and sometimes the talent changes. In all cases it helps to see who did what and why they did it at that time.
I know a lot of people don't like HN, 95% of the code I work on is engineering simulations and there was a time when mixed type expressions got you in trouble. I always used isFoo for boolean functions, and the blnFoo for loop flags.
I was wondering if you meant a x.00 format as 'double' for monetary variables, or if you were planning the Superman 3/Office Space fractional penny hack.
I can buy most of these, I would add that I like to include the type in the name when doing math (bln for boolean, i or int for integer etc.). I also make sure when it's declared that it's unit is defined in the declaration. I can't tell you how many times I've looked at 'temperature' and wondered if it's oC, oF, K or oR.
My comment about comments in code is that all comments need a date and the coder's initials as a minimum, and old comments should not be deleted. I have way too much experience knowing why these are my comments.
I think the problem isn't necessarily age discrimination, but the skills silicon valley companies and web companies need are simply different to the skills us older folks have. We cut our teeth on older tech (Physical Hardware, Main frames, SANs, building our own Datacenters and Networks, Compiling Kernels, etc) that's been replaced with new modern cloud stuff (do it all on AWS, used hosted services, etc.)
This. My friend is working in a Valley company that is 'going through changes' and if you are not working on 'the cloud' and you are resistant to 'the cloud,' then you will be looking for 'a job.' It's being implemented ruthlessly.
They had intended to have Irrfan Khan play Venkat, but he wasn't available. Can't blame them for having Chiwetel, he is an excellent actor.
The movie was good because the book was short.

Review: The Martian
·
· Score: 5, Informative
I liked the movie a lot, and I was surprised about how almost everything in the book made it into the movie. Then I realized it was because the book was short. The Lord of the Rings is great, there is no way to put all of the material into the movie when you have 10 times the words that the script needs.
Of course there were a million nits, technical and otherwise, but they made a good movie from a good story.
Was it only the panels or the inverters, rails, etc.? I got a 5 kW system (4.3 AC) with microinverters and the panels cost about 1,100 per kW and another 5,000 for the inverters, rails, conduit etc. Labor etc. was another 1,000/kW (rebate makes it much cheaper).
There are fewer than 1 million people in SF, but it's also relatively small. I think the big problems are the very hilly streets that plateau at the intersections and cars parked end-to-end along the sidewalk. Drivers make right turns (or left turns at one-ways) from a downhill at green lights without seeing if a pedestrian is on the crosswalk (this happens especially during high traffic periods); every corner is virtually blind.
That, and the taxi drivers are some of the most aggressive I've seen.
Pretty interesting really, my first thought was that the pressure was too low, but the Martian atmospheric pressure is right near the triple point of water. For liquid water to be there the pressure must have gone up above the nominal 600 pascals to 611 or higher, and the temperature above 0 deg C.
I read the book, but I'm wondering how much mass the dust has. Momentum is density*velocity, if you have a kilogram of dust moving at 100 meters per second, the momentum would be 100 newton-seconds, not a huge amount, but more than the very thin atmosphere of Mars.
Do they have dust storms at all? I know the density of the Martian atmosphere is minuscule, but if it were carrying dust particles the overall momentum transferred to the ship could be at least measurable.
Remember the Scrubs episode where they noted that except for births and emergency room visits, one out of three patients in a hospital will die? Then they showed three patients, and all of them died.
Never said cyclists don't use less energy. They use less energy, but they use it terribly inefficiently. And no, nobody burns "excess calories that they would have already eaten". The reason you get hungry after exercise is because you're burning calories. If you start burning an excess of calories and never eat more to compensate, you will starve to death.
If you ride your bike an hour, you'll burn about 500 calories. If you drink two beers worth drinking, you'll consume 500 calories. The average person has a pretty large variance in caloric intake and an hour exercise isn't going to change the food distribution of the world. So it's not a stretch to say that extra food consumption from cycling isn't going to affect the environment at all, when comparing to moving a 1000 kg car with the 90 kg person inside it going the exact same distance with the goal of getting that person from point A to point B. Nor is a single person driving a car, I think we're in agreement on that. The cyclist commuter wins easily. Especially if you go back to the petrol and car supply chains like you did with cyclists food (after all, oil wells don't drill themselves, nor does gasoline refine itself, nor do cars spring magically from the earth...all of these require tremendous energy.
And of course it's risk of death per mile that matters, not per time or per number of trips. Are you going to quit your job and pick a job closer to your home when you switch to the bike too? You have the same destination as in the car, just a different mode of transportation. You have to do the same number of miles.
This would be true if all miles were the same, but they aren't because of hills. My 10 mile bike ride takes 45 minutes where it would take me 30 minutes in Florida. Plus, probability math would use a timescale, not a distance. More important considerations would be the road configuration, traffic per lane, clearance between the car lanes and bike lanes, and the blood alcohol content of the driver and cyclist. Apparently it's more dangerous in the UK than the US, our fatality rates are 1:2. Clearly the UK roads are more hazardous to cyclists than American (because I know that the Brits drive better than we do).
The average Briton cycles 53 miles a year. The average number of car miles is 8200 - 155 times more mileage. Looking at the same year's accident statistics, 801 people died in cars and 8232 were seriously injured. 110 cyclists died, 3222 seriously injured. That's 7,3 times more deaths and 2,6 times more serious injuries for cars... which go 155 times further. Even if you factor in 100% of pedestrian deaths to cars (and hey, are we forgetting that we still need goods hauled around?), they're only about half of the car casualties, so it doesn't even bring the numbers close too each other.
Sorry, bike nuts. Your mode of transportation is horrible for the environment and horribly dangerous per mile. So stop trying to make us all take part in your stupid hobby.
By the way, I'm not saying don't drive your car, I'm just calling BS on saying that cyclists are less efficient than cars when considering commuting. And it is more dangerous, but not extraordinarily so.

One thing from the summary, are they limited to two children or could they have more?

I'm guessing this hoverboard doesn't meet your criteria either.

There is not enough lithium on the planet to store the energy needed, so another battery material is needed.

Because human nature for many lets me down more often than not, my thoughts on where this will go.
I'm gonna refer to the Han Solo quote on this one (and I'm not talking about the Kessel Run).
You caught me not reading TFA, although it does raise the question when/how the salt was dissolved in water in the first place.
I wonder if the authors are suggesting that the rocket fuel for a return trip can come directly from the surface soil.

Love that show.
AFAICT, the article is discussing receiving the fast radio bursts, not sending them.
