US Successfully Tests Self-Steering Bullets 216

mpicpp sends this report from The Independent: The United States Department of Defense has carried out what it says is its most successful test yet of a bullet that can steer itself towards moving targets. Experienced testers have used the technology to hit targets that were actively evading the shot, and even novices that were using the system for the first time were able to hit moving targets. The project, which is known as Extreme Accuracy Tasked Ordnance weapon, or Exacto, is being made for the American government's military research agency, DARPA. It is thought to use small fins that shoot out of the bullet and re-direct its path, but the U.S. has not disclosed how it works. Technology in the bullet allows it to compensate for weather and wind, as well as the movement of people it is being fired at, and curve itself in the air as it heads towards its target.

There will never be anything other than a politically-motivated, secret back-room solution to any problem. Solutions will be chosen based upon who benefits, not upon whether they are actual solutions.

This is the world we live in where the incompetent shitbags float to the top and ends up in Washington while the competent people remain trying to do competent things in the face of an endless stream of policy waste from those same shitbags.

Comment Our local generator has three huge batteries (Score 2) 334

Our local nuclear station has three enormous batteries that hold GWh of electricity for peak times. They are called Lakes Jocassee, Keowee, and Bad Creek.

During the night when the nuclear station generates excess power, water is pumped uphill through the succession of lakes. During the day, when peak demand hits, water flows downhill to generate extra power. It's efficient and relatively cheap to maintain over time.

The surfaces of Bad Creek (at the top) and Jocassee (in the middle) can fall tens of feet over the course of a few hours. Keowee (at the bottom) is maintained level as it is also the source of cooling water for the reactors.

It's a pretty cool system, and having the manmade lakes has generated billions in economic activity for the area in real estate, recreation, and tourism.

Comment Answer: You don't. (Score 1) 634

The reason there are fewer women than men in engineering is not because of some grand societal mechanism of oppression. It is because men and women are not the same. This goes back millennia. Our predisposed gender roles are baked into our DNA.

I have a much better idea. Why don't we stop obsessing over making everyone on the planet exactly the same, and let people do for a living that which they like and enjoy doing? Women who want to become engineers will become engineers.

It is a time-limit on damages, which is not the same thing as a time limit on lawsuits. There is still the potential to restrain an infringer who started 6 or more years ago from further infringement through the courts - and totally kill their business - even though damages for the infringement can not be recovered. And you can sue any other infringer.

A Cheap, Ubiquitous Earthquake Warning System 101

Tekla Perry writes: Earthquake alert systems that give a 10 or 20 second warning of an impending temblor, enabling automatic systems to shut down and people to take cover, are hugely expensive to build and operate. (One estimate is $38.3 milllion for equipment to span California, and another $16.1 million annually to operate.) But a Palo Alto entrepreneur thinks he's got a way to sense earthquakes and provide alerts far more cheaply and with much greater resolution. And he's got money from the National Science Foundation to begin the first test of his system — covering the Bay Area from Santa Cruz to Napa and the cities of Hollister, Coalinga, and Parkfield. He starts that test next month.

Comment Re:This is a response to RISC-V (Score 1) 63

Repeating the AC because he's posted at karma 0. That's "University of California at Berkeley", AC, but the rest of this is spot on:

Berkeley University is pushing really hard to get universities to adopt RISC-V (an Open ISA and set of cores) as a basis for future processor and architecture research. The motivation behind RISC-V was to have a stable ISA that isn't patent encumbered, isn't owned by one company, and is easily extensible (OpenRISC didn't fit the bill here).

I can see that ARM and MIPS would have a problem with this, especially as there is nothing particularly innovative or performance gaining about either ISA, and some recent RISC-V cores have demonstrated similar performance to some recent ARM cores in half the area. This is there way of fighting back against something open that stands to lose them significant marketshare.

Cool. Someone found us the agenda!

I get paid to train EEs within large companies on intellectual property issues, and to help the companies and their attorneys navigate those issues. Infringement is rife within software companies. Not because anyone wants to infringe, but because of a total lack of due diligence driven by ignorance.

You've made my point for me.

And any informed patent holder knows that any violation must be prosecuted, or the validity of the patent evaporates.

No, that's just the ignorance of the uninformed that "everybody knows", but it's wrong. You don't lose your patent from failing to enforce it. You might be confusing it with trademarks, which can go into the public domain if you allow them to become generic terms rather than specific brands. And you can sometimes lose the capability of being able to enforce against a specific infringer if you hold back until the market develops, that's the Doctrine of Laches. But you don't lose your patent. Nor would you lose your copyright due to failure to enforce.

Submission + - WSJ Frets That Brenda and John Romero's Kid Not Taught to Code at School

theodp writes: To paraphrase Jeff Foxworthy, Microsoft might have succeeded in fabricating a K-12 CS crisis if the Wall Street Journal frets that Brenda and John Romero’s kid isn’t being taught to code at school (yes, THAT John Romero!). By all other accounts, their 10-year-old is doing just fine from a coding perspective, leading a team of 7 in the development of Gunman Taco Truck.
