In the US, up to 328,000 birds are killed each year by wind turbins (http://www.sciencedirect.com/science/article/pii/S0006320713003522)
That's not a lot; cats kill somewhere between 20 and 120 million birds a year.
In addition the problem is being actively worked (http://www.audubon.org/news/will-wind-turbines-ever-be-safe-birds) and hopefully that number can be lowered significantly.
Or you can just install Tesla's Powerpack (https://www.nytimes.com/2017/01/30/business/energy-environment/battery-storage-tesla-california.html?_r=0)
store the electricity and sell it off later.
Not OP but I'll give you a better example.
Let's say you are processing the temperature data of all of the US over 20 years, tens of thousands of weather stations with multiple readings per day. It's likely that some of those malfunction every now and then. How do you know which readings are correct and which are not? Well you can eliminate the outliers.
You take an area and you look at the temperature readings - if they are all around 75F plus or minus 3 degrees, but you have one that's showing 90F, there is pretty good change that one station is busted.
That's exactly how they deal with the urban island effect. Temperature readings in cities are higher due to high area of pavement/concrete, so instead they use the readings from a rural area nearby.
In the end you don't care about the ups and downs, you smooth those over and you look at direction of the average. I

He didn't misunderstand, he misrepresented the facts to fit his narrative. I don't know if he knew what he was saying was not true or if he was simply regurgitating what his staff fed him, but the end result is the same.
The rocket's efficiency can be measured in dollars and the fuel is cheap - only 1% or 2% of the cost of a launch is due to fuel. So having to carry all that reaction mass is not that big of a deal after all.
We've had ISS for decades, as well as HI-SEAS, a Mars hab test site. I think it's safe to conclude living without atmosphere is well understood.
To get to colonization you need to start with a sight-seeing trip, after all that's how America got colonized.
We've had Mars Direct, a Mars mission concept that we know is viable, since 1990. There are legit reasons to go back to the Moon but testing is not one of them.
NASA's budget is $17 billion and they are spending 20% of that on the ISS. If you want to lobby Congress for more money for NASA great, but I don't see it happening. In the mean time NASA should consider what's the best use of it's money.
Buzz wants to get people to Mars, which is great, but there are other opportunities as well. For example just 1 year of ISS spending can pay for the Europa clipper ($2 billion estimate) plus a lander (another $1 billion), a leading candidate for finding extraterrestrial life. Or pay for WFIRST ( $2.7 billion), a space telescope that will search for dark energy and will be able to image exoplanets.
ISS is great and all but it's growing expensive to operate and we have to ask ourselves if it's worth it.
If Bigelow or another private company wants to put up a module and fly tourists to it fine, but I don't think private industry is ready to run the ISS. A better way to lower the cost is to get more counties involved, China being the most obvious choice. India might also be interested.
Turbo Pascal here as well. I think they should still teach that as a first language, very consistent language and the english-like structure makes the code extremely readable and easy to follow for a beginner.
There are no unused visas - my understanding is that they all get assigned.
If H1Bs are limited to 10% of the company's payroll, more companies will be able to get visas and the sweatshops will be eliminated.
The H1B visa is kind of portable but not really. The company that's hiring the H1B holder still has to apply for visa and go through the whole process. That's complicated and expensive so a lot of companies don't do it thus making it much harder for a H1B employee to jump ship.
That will just push all H1Bs into high cost of living areas. I would think a company in Oklahoma has a much more legitimate need for H1B workers than one in Cupertino.
In some countries Master's is the default degree - university is 5 years and you have to write/defend a thesis. Not sure if that's the case in India, but that could explain why everyone has MS.
I've worked in companies where we couldn't hire H1-Bs and there was very acute shortage of qualified candidates, despite being within a 5 mile radius of a major university.
I realize there is some abuse but I think there are ways to address that without crippling the whole sector.
One thing could be to limit the number of H1Bs a company can hire to say 10% of the company's workforce. I've heard a handful of large Indian consulting companies get a large share of the H1Bs that are allocated.
Another measure would be to require companies applying for H1B to pay a large fee but make the visa very portable so that the worker can switch employers at will once they have the visa. That should ensure that the workers are paid market rates and not exploited. I knew a H1B, a US college graduate, who was expected to work 10 - 11 hours a day and his functions were expended greatly compared to the position he was hired in but couldn't do much because his visa was not portable.
I agree. Definitely Fox News' fault.
Before Fox News CNN reported actual news, now it's all panels of talking heads arguing with each other. And the more controversial, the better.
Unfortunately they did not have a choice, Fox's "news as entertainment" model killed their ratings and CNN had to follow. So did all the others. Ironically, the best news channels in recent years has been Al Jareeza America and they went out of business.

Yeah my sentiment exactly. My first language was TP and I can't think of cleaner, more consistent language.

Trump made such a huuuuuge deal about Obama's golfing and now, when he has spent 20% of his time as president golfing, he is getting a pass?
you forgot: Resistance is futile!

Lot's of coders on here... Yet, somehow, they think their job can't be outsourced...

Dumbest thing I've ever heard. So there is no shared reality then? 2+2 = 11 - based on my own principals and set of values?
