Comment So far the phone mfg with a public problem.. (Score 3, Insightful) 14

Is Samsung. They are talking *loud* about something they purport to be a super better thing. It would help their narrative if they make it sound like all the competitors are ready to fail at any moment.

So the competitors going along with it and making it look like Samsung is *leading* in battery safety would just play into Samsung's hands.

In terms of the actual relative merit, who knows, but from a perspective of marketable storytelling, it is very much not in the interest of Samsung's competitors to play up Samsung's process. If there is merit that their competitors are told about and recognize, expect them to silently improve their process, but in no way publicize that fact.

Comment if (window.changed) { window.render() } (Score 1) 68

You shouldn't be rendering a window every few milliseconds if it hasn't changed. This:

function paint {
        if (window.changed) {
                window.render();
        }
}

function render {
      window.gdiPaint();
      # In Windows, most screen elements are "window"s
      for child window.children {
                child.paint()
        }
}

Not this:

while true {
      window.gdiPaint();
              for child window.children {
                child.gdiPaint()
        }
}

If you enter on yellow it should be because you were going to fast and were too close to stop safely, so leaving before it turns red shouldn't be a problem.

Only if the yellow is long enough. I've seen many lights where if there's only one car at the intersection and you're turning left, you can enter on green and you'll still exit two or three seconds after the light turns red. A car approaching from behind at any speed even remotely approaching the speed limit would then enter on yellow without time to stop, but would have to slow down for you and would be unable to get out of the light until long after it turned red.

Comment Re:Sounds a lot like USB-Câ power delivery (Score 1) 63

I haven't been keeping up with the latest USB spec but this direction of power flow sounds like it would have been in breach of earlier USB specs for everything except USB-OTG which turning a device into a host necessitates the reverse of the normal power flow.

I believe USB-C and USB Power Delivery (USB PD) specs had this specifically in mind. They changed the fixed concept of one device being the host/master and one being the guest/slave in lieu of the devices being able to negotiate roles as needed.

In "classic' USB, you had two roles - a host, and a slave (or device). Power flows from the host to the slave, regulated and monitored so the slave does not draw too much power. The host also interrogates the slave to figure out what kind of device it is and all that other good stuff.

With USB-C and USB-PD, the roles are more flexible. First, the direction of power flow is no longer obvious. Something like a monitor may dock a laptop over USB-C, so the monitor is the device (and thunderbolt target too) but power is flowing from the monitor to the laptop to charge it. In classic USB, this can't happen - the laptop is forced to power the screen instead.

In USB-OTG, no power flows at all, though the present host will supply up to 100mA at 5V in case there's any circuits needing powering. If the roles switch, then the old host switches off its power and the new host turns on its power.lh

Comment Re:Wrong hole (Score 1) 133

No, the fact that you can unlock a phone with the finger of someone unconscious...

The phone only checks for liveness. If you're unconscious, then you're alive, and thus the fingerprint sensor sees it has a real living finger.

If you're dead, then it probably wouldn't unlock.

Comment No. p53 - the guardian of the genome. (Score 1) 99

All mammalian cells are constantly producing p53, and disposing of it. When they stop, repair or suicide should occur.

https://en.wikipedia.org/wiki/TP53

Once activated, p53 will induce a cell cycle arrest to allow either repair and survival of the cell or apoptosis to discard the damaged cell. How p53 makes this choice is currently unknown... First, the half-life of the p53 protein is increased drastically, leading to a quick accumulation of p53 in stressed cells. Second, a conformational change forces p53 to be activated as a transcription regulator in these cells....

Comment Quercetin (Score 1) 99

About a year ago it was discovered that the common dietary substance quercetin is able to kill senescent endothelial cells in the gi tract.

http://onlinelibrary.wiley.com/doi/10.1111/acel.12344/abstract

By transcript analysis, we discovered increased expression of pro-survival networks in senescent cells, consistent with their established resistance to apoptosis. Using siRNA to silence expression of key nodes of this network, including ephrins (EFNB1 or 3), PI3K, p21, BCL-xL, or plasminogen-activated inhibitor-2, killed senescent cells, but not proliferating or quiescent, differentiated cells. Drugs targeting these same factors selectively killed senescent cells. Dasatinib eliminated senescent human fat cell progenitors, while quercetin was more effective against senescent human endothelial cells and mouse BM-MSCs. The combination of dasatinib and quercetin was effective in eliminating senescent MEFs. In vivo, this combination reduced senescent cell burden in chronologically aged, radiation-exposed, and progeroid Ercc1/ mice. In old mice, cardiac function and carotid vascular reactivity were improved 5 days after a single dose.

Comment Re:IPv6 tunneling (Score 1) 49

What are the reasons for an ISP to do IPv6? People still can go to Google with IPv4, so no reason there.
Not enough people will change provider over this, so no incentive there.
They are now able to ask extra money for a fixed IP address, because IP addresses are scarce, even though this would mean that you can't get an IP address instead of not getting a fixed one.
They would need to invest and that is never a nice thing to do.
They need to replace a lot of hardware or at least reconfigure it and that will cost money.
Also an extra layer that can fail, so extra cost.

In all this I do not really see a reason for a provider to move to IPv6, besides the 'It is a cool thing to do' type of thing. As a business I would also be against it.

I hope I am wrong and somebody can tell me a lot of advantages that would make them money, save them money or a combination of both.

Comment On $400 billion investment (lost money after infla (Score 2) 66

Amazon made $2.37 billion, on over $400 billion invested. So an owner (investor) who put in $10,000 of their retirement savings made $59. Whoohoo!

Due to inflation, $10,000 in 2015 was worth only $9,700 in 2016, so they actually LOST $241.

Yeah, "making" less money than you're losing to inflation is pretty dismal.

I think it's worse than that. The guy's movie netted big and yet he feels his movie should have been entitled even bigger windfall despite having plot holes that Superman can throw a container ship through.

Rotten Tomatoes has a Critics score *and* an Audience score. A lot of popular movies have a higher audience score. BvS has a 63% audience score. Iron Man 3 got 78% audience score. Lest it be a Marvel v. DC thing, The Dark Knight got 94% audience score *and* 94% critic score, so it's not like so many reviewers are snobs about comic book super hero movies.
