Comment Re:Glitchless streaming. (Score 1) 124

One way that might help is to use DSCP to assign classes of service to traffic. The problem, of course, is that DSCP can be abused. With proper settings things like bittorrent or downloading files would be assigned a low priority whereas voice traffic would be assigned the highest priority. I do this internally on my own network for upstream bandwidth so my backup traffic does not interfere with other data streams. It also means that no matter what someone may be torrenting it won't affect higher-priority traffic. Right now all traffic is basically treated the same with some heuristics to try and optimize different traffic streams. As long as there's no congestion there isn't any problem. When congestion occurs, though, things break down.

I think many of us would like to see traffic managed in a fair but responsible way where for example an ISP doesn't give preferential treatment to one video provider over another.

The problem with all of this is that it requires trust that the content providers are properly marking their packets, i.e. someone isn't marking all their bittorrent packets as high-priority.

Comment Loss prevention is more interesting feature! (Score 1) 58

With so many sources of weather forecasts, with news, with notifications, an umbrella doing the same thing is pretty meh... That the umbrella pairs with phone to help either from getting lost -- that's a feature possibly worth $105. Until the umbrella blows inside out, then I'm back to $10 ones.

There is no cap on the device to be "destroyed" in this case since there is no diode going between a data line and +5v. In fact, the way that the "killer" device is designed the -240v will just be shunted directly to ground through a diode. I'd be more worried if it were +240V since the zener would also be involved.
The caps on the killer device don't hold a lot of charge since they're rated at a minimum of 240V unless they're quite large. With capacitors there's a tradeoff of voltage vs capacity for a given size. I'd argue that the device would be far more destructive if it pumped -12v instead of -240v since it would be able to output a lot more current.

Actually the schematic I'm looking at uses a Littelfuse SP3011 protection circuit for USB 3 which uses a zener diode. It clamps the voltage to ground and the zener and can handle spikes of 40A and +/- 8KV. The nice thing here is that it protects any spikes from being sent to the power supply.

Submission + - Nikola Motor Company Reveals Hydrogen Fuel Cell Truck With Range of 1,200 Miles (

An anonymous reader writes: Nikola Motor Company just unveiled a huge class 8 truck which will run on hydrogen fuel cells. Nikola claimed that the truck’s operational range will be as much as 1,200 miles (1,900 km), and it will be released in 2020. Nikola designed the Nikola One for long-haul transport across a large landmass. The truck will deliver over 1,000 horsepower and 2,000 foot-pounds of torque. Provided these claims are true, the vehicle will provide nearly double the power of the current-gen diesel-powered semis/articulated lorries, notes Ars Technica. The leasing cost of the trucks will include the fuel price, servicing costs and warranty, but exactly how the lease will work is not known now, notes Ars Technica. The company says it has already accepted nearly $3 billion in future orders. A fully-electric drivetrain which gets power from high-density lithium batteries runs the vehicle, and a hydrogen fuel cell charges the batteries on the go. Its reach is presently limited, as hydrogen fueling stations currently exist in only small numbers. This made Nikola decide to construct a network of 364 hydrogen fueling stations across the U.S. and Canada, just like Tesla with its network of Superchargers. Milton claims it will come with a smart dashboard which has the capability of picking the most cost-efficient route for drivers. Also one or two full-size beds will be included inside the vehicle’s enormous cab. It will have other luxuries and necessities as well, such as Wi-Fi, a refrigerator, 4G LTE connectivity, freezer, a 40-inch curved 4K TV with Apple TV and a microwave.

Submission + - The forgotten story of America's first toy robot ( 2

harrymcc writes: In 1954, the Ideal Toy Company released Robert The Robot, the first toy robot made in the U.S. He was made of plastic instead of the more common tin, had a hand-cranked remote control and talked. And he not only became a bestseller, but appeared in a movie, inspired songs, and was generally a media superstar. And then everyone forgot about him. Over at Fast Company, Jared Newman chronicles his odd and interesting story.

Think about the power to weight ratio--with as little as a plastic vehicle with a passenger or two would weigh on Ceres, the ratio would be very high, especially after they found the ferromagnetics in the belt that could be magnetized a hundred times as strong as today's (that story, "The Pirate", is still in edit), replace the magnets in a 100 watt motor with them, and one watt will run that motor as well as 100 did the old.

They already had real moon buggies, they're still up there. They used wheels, but the moon is a LOT heavier than Ceres.

Imagine playing basketball on Ceres? I might add that to a story, there were microgravity sports in "Mars, Ho!".

Comment Re:Hard drive or software? (Score 1) 106

I don't back up daily, more like weekly, plus whenever I have a rash of new data. I keep the backup drive unplugged except when backing up, and never in s thunderstorm. Losing my non-backed up data would only hurt a little, it isn't like I'll lose a 10,000 customer database or anything.

Before I retired, backups were automatically done daily by software. I had to change the backup tapes weekly.

Journal Journal: Santa Killed My Dog!

They say that Santa's coming,
He comes 'round every year.
He comes he'll meet a shotgun slug
'cause he ain't welcome here.

Five years ago this Christmas
The fatass came around
With jingle bells and ho ho hos
And looking like a clown.

He came in for a landing
As I let out a yawn
My house is pretty little
So he landed on the lawn.

Comment Re:EV dongles? (Score 1) 72

Dongles tend to be a lot heavier and difficult to manage when dealing with that amount of power. There is an adapter for Tesla to use ChaDeMo and it's fairly large, in part due to the huge size of the ChaDeMo connector compared to the Tesla connector. There is also the problem where this charging standard uses a much higher voltage than CCS, ChaDeMo or Tesla standards which all use a similar voltage range.

Those were all bad presidents. My grandmother, born in 1903, said Coolidge caused the depression but Hoover was a terrible president, too. Most historians consider Lincoln's predecessor, James Buchanan, .was history's worse.

I never thought I'd ever see a worse president than Carter, but GW proved me wrong.
