Drought and Desertification: How Robots Might Help 124

Hallie Siegel writes Groundwater levels in California's Central Valley are down to historic lows and reservoirs have been depleted following four consecutive years of severe drought in the state. California is set to introduce water rationing in the coming weeks, and though the new rationing rules will focus on urban areas and not farms for the time being, they serve as a warning bell to farmers who will inevitably need to adapt to the effects of climate change on food production. John Payne argues that long term solutions are needed to help make agriculture drought resistant and looks at some of the ways that robotics might help.

FBI Accuses Researcher of Hacking Plane, Seizes Equipment 270

chicksdaddy writes: The Feds are listening, and they really can't take a joke. That's the apparent moral of security researcher Chris Roberts' legal odyssey on Wednesday, which saw him escorted off a plane in Syracuse by two FBI agents and questioned for four hours over a humorous tweet Roberts posted about his ability to hack into the cabin control systems of the Boeing 737 he was flying. Roberts (aka @sidragon1) joked that he could "start playing with EICAS messages," a reference to the Engine Indicating and Crew Alerting System.

Roberts was traveling to Syracuse to give a presentation. He said local law enforcement and FBI agents boarded the plane on the tarmac and escorted him off. He was questioned for four hours, with officers alleging they had evidence he had tampered with in-flight systems on an earlier leg of his flight from Colorado to Chicago. Roberts said the agents questioned him about his tweet and whether he tampered with the systems on the United flight -something he denies doing. Roberts had been approached earlier by the Denver office of the FBI which warned him away from further research on airplanes. The FBI was also looking to approach airplane makers Boeing and Airbus and wanted him to rebuild a virtualized environment he built to test airplane vulnerabilities to verify what he was saying.

Roberts refused, and the FBI seized his encrypted laptop and storage devices and has yet to return them, he said. The agents said they wished to do a forensic analysis of his laptop. Roberts said he declined to provide that information and requested a warrant to search his equipment. As of Friday, Roberts said he has not received a warrant.

So you're saying that a dead 2 year old, who had already had half her brain removed and the other half was seriously damaged, and dunking that in liquid nitrogen with the hope that someday a new body could be built for her and she'd be perfectly normal again ... is a con?

Oh ... ya ... it is ...

I don't know how the fuck anyone falls for it. Really... Why would they think that even if their bodies were preserved that long, and the technology was invented to create what's missing, and repair all the damage done by the freezing process, that anyone would spend the 14 bazillion New Earth credits (or whatever currency there is in futureland) to bring some old fucker back?

In her case, the could have just saved a DNA sample. The story is clear about the condition her brain was in. Half was gone. The other half critically damaged.

I'd have to think that it would be questionable in futureland to resurrect a 20th century person, even if they were in pristine condition. Say 21 years old with much above average intelligence, who was taught everything that there is to know, with no medical issues, no trauma. Just frozen as-is without cellular damage. Why would anyone opt to wake them up? Just to ask "Hey, so what was life like in the 20th century?"

The whole cryogenics "industry" is a huge con.

If these people are religious in the least, they'd have to believe that the soul was trapped in that frozen body until it was awakened. If it wasn't, there would be no reason to reincarnate them. What if they picked the wrong part to freeze? Like, if the soul was really in the liver, or maybe in the spinal cord between C1 and C3. Oops, sorry, we cut that part off.

And if they aren't religious in the least, why bother? So they can wake up as a curiosity in the future? "Hi Cro-Magnon. Fire hot. We have spoken languages you don't understand. And try to wrap your mind around these three seashells. No more poison ivy toilet paper for you. No, don't hit females with a club to make them your mate/slave."

Microminiature accelerometers are really cheap and very very light, and you don't have to wait for them to spin up or deal with their mechanical issues. I doubt you will see a gyro used as a sensor any longer.

Similarly, computers make good active stabilization possible and steering your engine to stabilize is a lot lighter than having to add a big rotating mass.

A video from the barge is now online here. If you step through the final frames, you can see that the camera mount ends up knocked over and pointing at the ocean, but the lens and its cover are unbroken and all we see flying appear to be small debris. So not a really high-pressure event.

It's very tempting to think this should work like an airplane. Lots of people wrote that it was "too hot", etc. But it isn't an airplane. The plan was really to approach at 1/4 Kilometer Per Second, then brake at the very last second.

Obviously Crew Dragon, which carries people, will approach differently. But it's a lot lighter.

It looked to me that the barge was structurally undamaged but that some heavy equipment on the deck was forcibly ejected. It's clear to see in the HD version. Those 1000 HP thrusters are expensive, and it looked to me like one of them going overboard. But I suspect they were prepared to lose more than one vessel in testing this.

And I bet there was a range safety self-destruct charge onboard. F9R blew itself up with one. But it was probably so safe that it didn't go off.
