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.

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.

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.
