A radar activated light... so that the driver of a car knows that the cyclist knows that the car is getting closer to the cyclist? Huh? How about just a light that blinks really fast to begin with, and a rearview mirror on the bike so the cyclist can see the car, rather than depend on LEDs to tell him there's a car behind him. Total savings, several thousand dollars and the heartbreak of putting your heart and soul into a project that will never go anywhere.
If the inventor was bound and determined to go high tech, then how about handlebar a mounted smart phone with a rear-facing bluetooth camera. Putting together some image processing software that recognizes something approaching from the rear and notifies the cyclist with a flash or a tone would be a lot easier than building a radar, and you get the added bonus of having the rearview camera image on the smartphone display too.
Either way you are using off-the-shelf hardware. As it stands, at the frequency he's working at, in any kind of weather that diminishes visibility to the point where you'd want to have it, it would be useless. 24GHz will give you returns off of humid portions of air, let alone actual smog, fog, or mist, and doppler isn't the be-all-end-all in an environment where air currents and gusts can move the stuff you're getting returns off of at the speed of a car.
I hope those venture capitalists haven't put real money into this.
What if you could have a shell you had to sit out and plan a custom UI for? What if you had a shell that took one of your most excellently trained typing hands away from the keyboard every command or two to make you do stuff with the mouse. What if you had to pay kickstarter money to get this shell rather than stick with existing open source tools?

Sure, local dealerships can fight over the scraps over who will take the lowest cut. And the manufacturer, who sets the "cost" price that the dealerships pay, is who laughs all the way to the bank. So while dickering on a price isn't possible with Tesla, it's also not possible with the existing dealership model. You can't go to ten dealerships and tell them, ok, which of you is going to more aggressively call up Ford and get me a better price from them?
So yes, you can negotiate for a dealership that adds less markup on top of what they pay, why introduce that layer at all anyway?
Most everyone is aware of the ESR. This is just a bandaid over the real problem. Chrome was designed from the very beginning with a rapid release schedule in mind. Release numbers in Chrome are essentially meaningless. Firefox adopted the same rapid release schedule as Chrome in a project that wasn't designed for it either technically or from a project management or project cultural perspective. Firefox gave addon developers the finger as they constantly broke extensions and themes. They carelessly spent valuable resources trying to make Firefox extensions less reliant on versions numbers, which only more badly broke legacy extensions, and rather than using resources to actually help extension authors, they wasted them on semi-automatic systems to catch non-compliant extensions and disable them. Which left users high and dry when they were forced to upgrade (lest they get left behind on security fixes) and lose functionality. More and more UI changes were forced on users, despite in some cases, clear majority opposition. Mozilla has consistently adopted a "we know best" attitude when it comes to what users want. And it shows, with marketshare stagnant. Google is still a major funder of Mozilla, and it's easy to see they think it money well invested. They make Chrome and then pay Mozilla to implode trying to slavishly copy their success.
Who wants to go to an ESR that is a bandaid on a bad system? You just place yourself in the eye of the storm for a short time.
No project can emulate another project and outcompete it. ESR's are not the answer. I personally have moved to PaleMoon. It too is based on a Firefox ESR, but at least they are committed to sane development and user-based UI decisions.
Imagine the world we'd live in if the "Voyager" kind of engineer had more say in how society worked?
Indeterminate in the extreme?
Why elliptic curves when we can go back to good old fashioned original RSA that uses prime number factoring as the problem? No patent nonsense to worry about there.
All we know for sure is that a woman is claiming a man violently attempted to rape her, and the man is apparently denying any such thing happened. As far as the other 99.99999% of the world is concerned, either side could be telling the truth. We have no way to know. We have no appropriate way to find out, unless people are advocating a Boston Marathon type witch hunt. And given what happened there, I am surprised and disappointed that Slashdot posted this.
Shame on Slashdot, and shame on anyone else who engages in the actual debate. Each side may be making public posts about what happened, but that does not make it our responsibility to indulge them in the wrong way to approach this. All this can do is serve to muddy the water to make it harder for any sort of proper official investigation.
Access will be intermittent, but in time the firm hopes to build a big enough fleet to offer reliable links to people living in remote areas. The firm says the concept could offer a way to connect the two-thirds of the world's population which does not have affordable net connections, but one expert warns that trying to simultaneously navigate thousands of the high-altitude balloons around the globe's wind patterns will prove a difficult task to get right."
The NSA isnâ(TM)t alone in the business of swapping secrets with the corporate world. The FBI, CIA, and Department of Defense (DOD) also have programs enabling them to exchange sensitive government information with corporate âoepartnersâ in exchange for access to things like information on cyberattacks, traffic patterns, and other information that relate to network security."

Requiring specific gestures could prevent the existing Face Unlock facility being fooled by photos. The software could monitor if there were changes in the angle of the person's face to ensure the device was not being shown a still image with a fake gesture animated on top."

So my first reaction was like most people, wondering what caused the staccato marks spread. But then I started asking, hey, isn't this stolen data? Sure the security sucked, but what efforts did he take to correct the problem or bring it to the proper attention before he announced to the entire whole world how anyone could steal personal information on hundreds of thousands of students? With detailed instructions.
This is at best unethical. Hopefully it's illegal in his jurisdiction.
The results look to me like some sort of scaling. In fact, if you load up Gimp, take a photo and go into levels and compress the input levels, when you go back and look at the levels again the graph will look almost identical to what these marks graphs look like. It looks to me like the marks spread is being expanded and the algorithm isn't smooth.
First of all I will concede that yes, you are right that weight is properly measured in newtons. I used the common reference of weight most people think of. However it seems I need to explain a little bit about inertia. I'll try to use small words so even NASA engineers can understand:
Curiosity wheel encounters rock. Wheel exerts force to lift itself over rock. To do this, wheel must lift all of Curiosity. Curiosity masses 900kg. Object at rest tends to stay at rest. Curiosity tends to stay at rest. Curiosity wheel has much inertia to overcome to make Curiosity start moving up and then over rock.
NASA test robot masses 342kg. Test robot wheel encounters rock. Test robot exerts force to lift itself over rock. Test robot has much less inertia to overcome to make test robot start moving up and then over rock. Test robot has few dings. NASA engineers cheer.
From the article:
“We have the same wheels on our Scarecrow test rover, which weighs the same on Earth as Curiosity weighs on Mars,” Heverly added. “We have driven Scarecrow about 12 kilometers (7.5 miles) in the Marsyard over rocks and slopes much harsher than we expect for Curiosity. There are some dents and holes in these wheels, but the rover is still performing well.”
This sounds an idea from the same people that brought us the Mars Climate Orbiter crater.
The problem with this is that Curiosity weighs 342kg but masses 900kg. Scarecrow weighs and masses 342kg. Whatever Curiosity weighs, it hitting a rock at 1m/s is still 900 newtons of force. Scarecrow hitting a rock at 1m/s is 342 newtons. The fact it drove 12km and has serviceable wheels does not make me feel better.
