I think that they have a list of approved ISPs or some dependable way to make sure it doesn't happen on metered connections.

http://windows.microsoft.com/en-us/windows-10/windows-update...

"As with Windows 8.1, Windows 10 won't automatically download updates or apps if it detects that your PC is using a metered connection. Similarly, Delivery Optimization won’t automatically download or send parts of updates or apps to other PCs on the Internet if it detects that you're using a metered connection."


Don't you actually have to specify that your connection is metered in order to that to work?

I think it's for tagging things like wireless hotspot, etc.



I wonder how they get those values, considering bandwidth limit parameters can vary depending on contracts even when it is happening to identical networks...

(Perhaps some UI allows users to to put this info, similar to Android settings?)


They have some samples that you could use: https://code.msdn.microsoft.com/windowsapps/Network-Informat...


What it does matter if it's metered or not? I've got metered connection, it's 10TB / month included + 1€/TB for excess (outbound). I don't usually worry about little extra traffic.


China does have 2.3 million active troops and 700 million humans who would be able to serve if needed.

They are considered the 3rd most powerful military.

What is the risk?


Unless they're going to swim or row, those 700 million humans who could fight if needed don't do much in a naval war.

The risk is, if the Chinese pick a naval fight and their navy gets pummeled, it's a PR disaster. That's a risk for the leadership, not so much for the country.


That's 700 million potential factory workers, military support staff, and soldiers, and the factories are already built, US companies paid for many of them.


so what does that have to do with naval warfare? You going to build thousand islands on sand during wartime?


They can't be invaded, but they can easily be blockaded. Now that China is an economic power, it is also vulnerable to disruption.

China's leaders are smart and they see that issue. I think that is one of the reasons they want to increase land trade through central asia.


Logistics. I don't think people realize that to move around army of even 10% of that 2.3 million, you require significant logistic support (sort of like upkeep in Warcraft 3). You then have to question which country has the access to most of the world's ports and bases outside of their own. Most importantly, you need to be on good terms and friends with these host countries. This is what China is going up against. A huge military resting at home means jack all if you can't mobilize it and upkeep it.

Most of them seem to have the same two chips in them, RTL2832U and R820T. Does anyone see an issue with this item I linked to? Some people were mentioning quality issues with generics.


Some sites just give off a vibe that prevents me from ever trusting them, LinkedIn is the most predominant in that category and I have never been able to put my finger on exactly why. The email proxy apps and the pay to see who viewed your profile aspects don't help.

I'm not saying that it's any worse than any other sites, but LinkedIn has always felt like a shady company, like they're not on the users side.

I was really hoping that the Google+ reboot would fulfill the niche market that LinkedIn dominates, but it did not.


The "best" feature they have is automatically sending notifications to all your peers (and through email) when you change one little thing in your profile. And they show specifically what you edited. You can disable it of course in settings, but you have to know about that. I've seen enough awkward situations come out of this. How is it even possible that they think it is okay?


I can see the rationalization: I've added React and Javascript to my LinkedIn profile, so it's probably nice to publish that to recruiters that I'm connected with, or friends who can endorse them.

Of course, I really don't want to spam them while I am rewriting prose about jobs until it's done, though, so it'd have been nicer if the spamming didn't happen until I pushed some kind of "publish" button.


its because they tell the user that you clicked their profile. what kind of bullshit is that, I wanna compare myself to other people without them knowing.


Try using the Incognito Mode in Chrome.

Of course, that will only give you a public view of a profile, but it seems to hide your identity nonetheless.


I think that AP is making some money from these videos by hosting them on YouTube.

https://www.youtube.com/watch?v=GjZ6NNLCdio has ads in the right sidebar (one of the newly uploaded videos).

https://www.youtube.com/watch?v=JC82Il2cjqA does not have ads.

https://support.google.com/youtube/answer/2467968


Do those ads only appear if the submitter enables it? Youtube has some ads by default. Either way I don't really care just curious.


It shows that they care about their product, their customers, and their brand.

Any other car company would save software updates for the latest years model and tell users that they have to purchase a new vehicle to receive the updates.

Great precedent Tesla, thank you, and I hope other car companies follow your lead.


The first public announcement was in October 2014.

They estimated they could build a test reactor within one year (by October 2015) and the prototype within 5 years.

John Deere didn't invent the technology though, Autonomous Solutions Inc. (ASI) did. They partnered in ~2000.

ASI were hardly the first, and Deere had their AutoTrac system before they started working with ASI.

I don't have any inside knowledge of the Deere system, but I'd be very surprised if it was. My guess is that most of the Deere stuff comes NavCom. That is certainly the case for their GPS system.

> "NavCom's involvement with Deere & Company began with Deere's GreenStar precision farming system in 1994 and has expanded into many areas of Deere's product activities. The commitment by the most senior Deere management to information systems leadership motivated the NavCom shareholder-employees to join with Deere & Company,"

You sure? Satloc was doing GPS guidance for aerial guidance for decades (crop dusting planes). They adapted it for ag guidance in the 1990s I believe. This technology has been evolving for years and saying that John Deere or some single company invented it sounds like a gross oversimplification.


It's not impossible:

Lasers have been used for 50+ years in the intelligence community to eavesdrop on voice conversations.

Hardware has to be radiation hardened and redundant.

Bandwidth is so low because it has to send radio waves 500 million miles, and that's not an exaggerated number.

Edit: The Deep Space Network is currently down, might be aliens, good luck everybody.


We have billions of dollars. USA already is experts at making complex, reliable and complicated hardware with complex manufacturing processes.

Why can't we just craft that hardware we need in bulk? We have billions of dollars in funding. Make a factory production out of it.

Why don't we send 300 mars rovers? We can make 5000 tanks. We can build 5000 fighter jets. Why do we just build one rover?

My impression with astronomy is it has nowhere near the fervor or seriousness that defense has. Why are we not dumping supply ships in the moon in anticipation of colonization?


I wrote a very detailed reply for this with lots of sources, but deleted it because it would only invite more questions that you can find out the answers to yourself. Really what you are asking requires several books worth of information to fully explain.

Basically just read everything on Wikipedia about DARPA, NASA, CIA satellites, the NRO, the Apollo missions, Sputnik, Voyager 1 / 2, the Curiosity rovers, KH-9, KH-11, Hubble, etc. then come back and criticize NASA if you still think that they are not doing their job properly.

You have the answers to all of these questions and more at your fingertips via Google.

NASA has another Curiosity rover, but the cost/benefit of sending it to Mars isn't worth it in their expert opinions.
