Comment Re:And us too - soon (Score 1) 394

We have freedom though.

"Freedom" is a loose concept that's made up of a collection of personal and collective rights. Among many, included are the right to privacy, the right to anonymous speech, and the protection against the unwarranted search of your effects. These are protected by law and legal precedent in the US because they are all critical to creating and maintaining a free society.

Mass government surveillance is a crack in the larger edifice of freedom and the chilling effects it causes will tend to make those cracks spread and get larger. And to make it all worse, the return on investment -- freedoms for promised security -- is a joke.

As others point out, we are orders of magnitude more likely to die in a car crash than an act of terror and yet people complain every day about seat belt laws. A rational re-evaluation of priorities is desperately needed today.

Comment Re:eating less (Score 1) 256

Well said. The only thing I would add is research shows that willpower is a limited resource and is depleted and replenished over time. A successful diet requires managing that resource and not starving yourself of willpower because that's when you fall off the wagon and the diet breaks or fails completely.

Finding ways to make yourself feel good about the diet and the progress you're making, along with normal day to day happiness is crucial for a successful diet. This is 10 times more important for people who use food as a form of comfort, which is a fair number of overweight folks.

Comment Re:Tizen proprietary? (Score 1) 122

Speaking of which, even Android is TiVo-ized, since you can't install your modified version of Android on your phone w/o breaking things

Just "breaking things" isn't what makes something Tivoized. It's when the system is designed to prevent executing custom or modified code through the use of something like digital signatures. A locked phone which normally runs a modified version of GNU/Linux and also refuses to execute code that isn't signed by the carrier would be an example of Tivoized hardware, but the Android software itself isn't Tivoized at all.

Comment Smart cables (Score 1) 90

The cables have an ID chip in them that will specify their rating as to amps and voltage, plus a few other things. If you read my USB-PD story linked above, you will get the details. In short both ends start at the USB base and negotiate up their capabilities for voltage and amperage for send, receive, or both. They will do this within the bounds of the cable connecting them, and while both sides have limited capabilities to sense the cable properties, they really depend on the USB-PD ID chip.

This ID chip is of course counterfeit-proof, something we know that low end manufacturers are not capable of cloning or getting around in, oh, say, 12 seconds. So in short DO NOT BUY CHEAP/NO-NAME USB-PD CABLES FROM EVEN A POSSIBLY QUESTIONABLE SOURCE. Amazon, I am looking at you. Really. 100W = big fire quickly.

Basically yes, but not necessarily operating the phone circuit at optimal efficiency. I think it is engineered to charge the battery as quickly as possible while minimizing damage/degradation to the cells. The charger circuitry efficiency is a big concern too, but secondary to preserving the cell life. That said this problem is optimization on a dozen axis or more, not just A vs B.

Comment Re:Never fast enough will lead to disaster. (Score 1) 90

The GN7 used QC2 from what I understand, likely because of their decision to split the GS7's SoC between QC and Samsung parts. I know that the phone version used QC2 because of lowest common denominator support and I am fairly sure that carried over to the Note.

That said the problem with the GN7's fires was not a battery defect but a manufacturing/assembly problem where the batteries were physically damaged and 'crimped' to the point where they internally shorted. I should be talking to someone today who probably knows if the QC-like tech has the ability to detect and stop this. I doubt it, but I am going to ask anyway.

Yes. First see what the guy below said (currently ranked 0 but worth a read), and then there is the responsiveness. USB-PD doesn't have the granularity and speed to deliver power in a way that won't hurt the battery. It can't shift quickly enough of finely enough to avoid hurting the battery. Could you do the same with USB-PD? Eventually yes, but it is really designed for charging laptops and powering big monitors, not for careful charging of mobile devices.

As was said below, you effectively have to dissipate the pressure of the firehose from USB-PD, QC3 and possibly others allow you to modify the inputs to your requirements from the source. This allows you to both match your input requirements precisely and to avoid generating heat at the source (charger) rather than on the device itself. Heat is REALLY bad for battery life, that alone makes schemes like QC3 worth it.

Both are fine but they don't actually address what QC3 does, they just deliver more juice. QC3 will change voltage in 200mV increments on the fly, allow 2 chargers for lower temps and better heat distribution, and actively monitor the battery for conditions which degrade life. There is a lot more to it, but pushing more wattage through USB-PD is REALLY BAD FOR BATTERY LIFE. I wrote up some pretty in-depth articles on both USB-PD and QC3 lined below if you care.

This is the long way of saying what Google is asking for is idiotic. If you look at the size of modern batteries and the rate at which USB-C can deliver power, we are bordering on all-night charges already. If you up the delivered power via PD, you will not meet the 500 charge minimum life carriers demand thus not sell any phones. Worse yet that number is about to go to 800 really soon if it is not already there. Plus you will have people pissed off that their phone is drawing more current than the charger is supplying while plugged in and being used.

In short I question Google's sanity on this one. I am asking around to see what the official take on this is from involved parties, but I suspect the original article's take is way off base. I won't say why yet, I like to know before I mouth off publicly.

You should check again and filter by SteamOS/Linux. Then sort by cost, you will see a fair number of triple A games there. Sure a lot are missing but my last check had over 1000 games available. If you don't NEED game-of-the-moment-X, there is plenty there to keep you happy for years.

Well, I strongly prefer an UI like in Windows 7 and want to be in full control of updates.

I completely agree with you, but full control over updates is no longer a selling point of Windows 7. Microsoft has moved to a single monthly rollup package for Windows 7 which always includes all previous updates and is only all-or-nothing. So, for example, the November 2016 update that comes out next week will include all updates from the August 2016, September 2016, and October 2016 update packages.

It's a step backwards in every possible way and exists solely to make it easy for Microsoft to shove whatever updates they want down their users' throats. The Windows 10 GWX fiasco has taught them a valuable lesson about the dangers of consumer choice and giving users control over their computers.
