Why expiration? So they can rip you off hundreds of dollars per certificate each and every year just to sign a few bits.

This is not an OS security issue. Trojans are never an OS security issue. Even if Microsoft forced users to run in user-level permissions, it doesn't stop Ransomeware because Ransomeware only targets user-level data.

If you have to use floating point values to store a number, it has inaccuracy. For example a simple penny counter algorithm that needs to break out of a loop when pennies remaining is less than 1 will misbehave when you're trying to check if .01 .011 if you stored .01 as a float. It will actually store 0.01 as 0.0999999999995 or something and that will cause the loop logic to fail. If you store in whole integers of pennies, you won't have this problem. So this concept of using Flicks allows you to use precise integers to describe frame rate instead of some funky float value that is imprecise.

Here's a story about prosecutors throwing people in jail for talking about prostitution by intimidating them with trumped up charges to get them to plea. Many got fired from their jobs. Others lost their friends and family and one man committed suicide. It's like how some cities resort to public shaming Johns which is such a horrific practice that even 18th century America stopped doing it. http://reason.com/archives/201...

All of these anti-trafficking organizations use Superbowl TV commercials of women and/or child being sold as slaves (which is extremely rare) but if you read what their true goal is, they want to stop all prostitution. They even consider 100% voluntary prostitution as trafficking. Amnesty International has the right solution which is to legalize prostitution so that women aren't forced into the underground where they are victimized by their Pimps and by the Police.

Robert does a nice job debunking Tim Wu's editorial. http://blog.erratasec.com/2017...

Tim Berners-Lee favored fast lanes which makes him support Pai's position on Net Neutrality. I quoted him 10 years ago here http://www.zdnet.com/article/a.... He said "Net Neutrality is NOT saying that one shouldn’t pay more money for high quality of service. We always have, and we always will."

Tesla can easily meet their claimed acceleration speed on the Roadster 2 with a 100 KWH battery that weighs 1200 lbs. In fact it's easier than hitting their claimed speeds with a 200 KWH battery that weighs 2400 lbs. All lithium Ion batteries can be pushed to 2X or 4X discharge rates to give you 2X to 4X the power. The penalty you pay for pushing the discharge rate is much fewer charge cycles before the battery reaches 50% useful capacity. That doesn't matter for a prototype or demo car but it's completely unacceptable for a production car.

A Tesla has an 85 KWH battery. Assuming close to 6 KG per KWH Lithium Ion battery capacity, we're looking at 1124 lbs. Good luck carrying an 1124 lb payload with a drone.

Final Cut Pro runs better on Mac than on a PC. News at 11.

Ah yes, the good of "Reversal of Proof" logic fallacy strikes again.

And yet they admit there are some thermal issues in your cited article. "He also admits that there are still traces of contamination caused by thermal expansion in the system". It still worth noting that these are tiny forces being measured and it's on the order of experimental error rather than useful thrust.

What should be most telling was that this "engine" produced more "thrust" when it was turned off than when it was turned on. That should tell you how stupid this thing is but everyone is so caught up in the "I want to believe" moment that they ignore all the warning signs.

The "thrust" measured by every study is so tiny that it's equivalent to the gravitational attraction of the contraption to your body. There are thermal effects that could explain this tiny thrust. So when the contraption was cooling off, the thermal effects were enough to push the air in a non-symmetric way that it produced a tiny push on the sensors. You could have measured more thrust just blowing on the stupid thing.

The future is 40-Gbps Thunderbolt 3 on USB-C connectors. You have up to 100 watts of power, multiple DisplayPorts, multiple USB 3.1 ports, PCI-e, and potentially 10-Gigabit Ethernet flowing on the same reversible cable. Nobody cares about having a bulky RJ-45 connector once USB-C gets popular. Even today people can easily add Gigabit on their USB 3.0 ports.

Again, using human power to turn a generator to fill a battery is a fool's errand. You're better off doing opportunistic regeneration on downhill and letting the person rest. Forcing a rider to output an extra 50 watts so that you can collect 30 watts in the battery is just idiotic. But the point was that even without regeneration, a single 26550 battery @ 98 gram and a 100 watt motor @ 50 grams is more than enough to win a race.
