The Android app does this now (and presumably iOS, though I haven't checked). I do think that hiding the comments below the suggested videos is a bit of a clunky user interface, but the video is kept playing. But yes, it'd be nice if the video was kept in view at all times on the desktop website.
Not sure what this has to do with Hangouts, though. The two apps come from very different teams within Google.
Nah, the construction cost of the satellite itself isn't all that important, not compared to the launch cost. The other commenters have it right: it's about orbital mechanics. You can organize the satellites in a triangle so that they maintain the same shape. I don't think it's possible to add a fourth satellite and keep it in an orbit that's actually stable.
I don't think that a fourth satellite would improve the science all that much anyway.
The reduced noise from not being near the ground is also a big bonus. But yes, the difference in detection frequencies is the most significant difference.
A currency is most useful if its value is stable: if the dollar in my pocket will buy me roughly the same amount of goods a month or a year from now, then that dollar is useful because I can make a promise for an exchange a year from now based on that dollar.
Imagine, for example, if your rent had been defined in terms of a number of Bitcoins per month for a year. The price of Bitcoins fluctuations so much over the course of a year that you might end up paying vastly more for rent by the end of the year than you paid at the start, or conversely you might end up paying vastly less. No reasonable person or entity would dare writing a long-term contract based on Bitcoin. And the rapidly fluctuating values make it dubious for most products, as they'd have to readjust the value frequently.
Maybe the concept of a blockchain could be useful as a medium of exchange, such that the buyer converts their money to Bitcoins and the seller converts it directly to the currency of their choice upon receipt. But I doubt it. It seems overly-complicated for the task.
If Bitcoins crash, and Ethereum takes over, then it's only a matter of time before Ethereum crashes and the next cryptocurrency takes over. But none of these currencies will ever replace government-backed currencies. Because they can't assure stable value.
For privacy, the simplest and most helpful thing to do is use full-disk encryption for your hard drive. This will significantly increase the amount of effort required to access your data and any online accounts (e.g. bank accounts).
For data, I just store all of my sensitive data on the cloud (e.g. tax returns, personal documents). If you have large amounts of important data such as photos, you may have to pay a monthly fee for good cloud storage. But it's definitely worth it. There are many, many other things that can go wrong besides theft that can cause data loss.
It's also good to practice good online account security (e.g. using 2-factor authentication), and make sure to reset all of your critical passwords in the event of theft of a computer.
Given that the Earth will become uninhabitable in about a billion years as the oceans boil due to the gradual increase in the Sun's brightness, I'm not sure that's a concern...
There may also be policies related to use of spaces vs. tabs at the specific companies people work for. For example, Google's C++ style guide requires using spaces for indentation.
My experience has been that spaces are markedly superior to tabs in shared projects, for the reason that different developers are likely to have different editor settings. If I write some code, I might not realize at the time of writing that I've accidentally mixed some tabs and some spaces. But the moment I send the code to somebody else who uses a different editor with a different tab setting, that code will have weird formatting. And even if the original author was consistent about using tabs everywhere, a different tab setting would make lines end at different locations, potentially making for odd line breaks.
I'd be willing to bet that this consistency argument makes it so that companies working on large codebases with lots of developers are more likely to require use of spaces than not, and they probably also have higher salaries.
It might be good if Trump, or any of his advisers, had the dimmest glimpse of a clue of how to add jobs. They don't. Simply having a "focus" is utterly meaningless if you haven't the faintest clue on how to achieve that focus.
For right now, the economy is doing reasonably well. That could change in a heartbeat if there's another financial crash due to the Republicans gutting financial regulations again.
We will continue to protect our community from unnecessary or overreaching government intervention.
Such as your real name policy that requires people use their legal names, making it easy for governments to track people through their posts, without compromising Facebook's systems?
People do indeed use refrigeration for PC cooling, but not in this way. They're referred to as Peltier coolers, and have been used by hardcore overclockers for many years. The idea is that the cooler itself is a small solid-state device that, when a current is passed through it, creates a temperature difference between one side and the other. You place the cold side on the CPU and the warm side connects to the heat sink (or other cooling systems).
Peltiers have many difficulties, however. They add total heat to the system, so you really need good case ventilation (or a water-cooled system). Without that efficient ventilation, your system ends up being hotter rather than cooler. Plus, as many people mentioned above with the refrigerator, they can have condensation issues if the "cold" side of the Peltier winds up below room temperature.
Peltiers can help, but in the end they are limited in the same way that the refrigerator case is limited: air is a terrible conductor of heat.
Well-designed water-cooled systems can easily surpass Peltiers or the refrigeration idea posted here, as water is a far superior conductor of heat.
I've long been more concerned about the TSA than terrorist organizations. Terrorism of this sort is not a significant threat in the US period. All that we get out of this kind of bullshit is more uncomfortable interactions with TSA agents, and more inconvenience. People in marginalized groups get the worst of it.
That's honestly a tall order, at least for the time being. Autonomous or semi-autonomous robots are still a pretty niche item, and I sincerely doubt terror groups will want to use one any time soon. For one, they'd likely be highly unreliable.
I don't see why it'd be any more difficult to just pack a bit more explosive in the luggage than smuggle a shaped charge through security.
Here are the actual power limits from the FCC, as of 2015. It's a little complicated, but overall 1W is the maximum output power allowed for Wi-Fi.
Either way, my bet is that the range of this technology would be quite short, far shorter than current cellular networks which operate at lower frequencies (meaning less attenuation) at at higher powers.
I really hope these trials continue and expand. A UBI would (I think) solve so many problems with market-based economies. If people have the genuine option of not working, then they will be more able to do things that will improve their productivity in the long run,
such as pursuing more education. The chronically-ill can also be supported without having to continually prove to the government that they are chronically-ill. Employers who are abusive to their employees will very rapidly find themselves without employees. And for people with good jobs already, they'll have the security of knowing that they'll be able to manage if the shit hits the fan and they find themselves out of work, even if unemployment benefits are limited.
More interesting to me, if they do something simple like fund the UBI with a flat percentage tax on income, then more than half of the population will end up with more money with the UBI than without (e.g. in the US, you'd need to make more than ~$70,000/year or so to end up with less money, and way more than that to end up with noticeably less, though the precise number depends upon the structure of the tax and the structure of the benefits).
A drone based in the vehicle sounds like the most likely solution to me. They could even have a few drones, depending.
Presumably they'd have users set out small emitters that tell the drones where to leave the packages, perhaps a Beacon or similar device. They could also have a number of differently-sized drones to handle packages of different sizes, though large packages would probably still have to be delivered by hand, I'm sure they'd just offload those duties to UPS for FedEx or similar.
I'm really, really skeptical that a solution like this could be cheaper than a human driver any time soon. They might be able to make it cheaper in medium-density urban environments by virtue of the trucks being faster by spending less time stopped, especially if they can deliver multiple packages at once using multiple drones. But I bet that will take time.

His focus on jobs is good? Seriously?
