Re: SpaceX News

The advantage of getting somewhere in 30 mins by rocket instead of 15 hours by plane will be negatively affected if "but also, you might die" is on the ticket. But, to borrow a line from a 1970's cartoon about an SST design: "This one is so fast, we were able to eliminate the restroo...

Re: Attn: Tom Ligon

He thought the tendency of the AIs to find workarounds for their safeguards was worth thinking about. Asimov had a few things to say about that. I think that may be the original inspiration for the strip. The Freefall AIs are not 3-laws robots, due to the flaws Asimov identified in that approach. T...

Re: Attn: Tom Ligon

There's another former Talk-Polyweller on Freefall's forum at the moment, posting as JohnDoe. Hah, a likely alias, I say! I'll see if I can get him to fess up his TP ID.

Re: EMC2 news

As I understand this sort of simulation, you may use a finite number of cells to simulate the volume, and probably in a limited part of the volume. Perhaps one quadrant is modeled and the rest are presumed symmetrical. Then you put discrete test charges in motion. So you model some number of discret...

Re: SpaceX News

Anyone want to buy a twice-flight-proven rocket?

The judges deducted a mandatory full point this time for poor video feed on the first stage descent, with the Russian judge deducting two points on account of it being (in accordance with the plan), boring.

Re: SpaceX News

Just a little tease, Aero.

I'd much rather you got that EM drive thing figured out. We could beat SpaceX to Mars.

Re: Skynet is coming.

Not a problem for civilian use, but a serious problem if you are making terminators. But a serious advantage if you're hunting terminators. With Cylons, listen for the clanking, then shoot at the red light. I suspect these are being considered for smart cars. Our new RAV4 has radar and a camera in ...

Re: EMC2 news

A key statement is made on Slide 8. Don't overlook what it means. It also couples back to Slide 7. Indeed. I did not mention this slide because, as stated, it lacks some supporting images that tell the real story. "The holes are closed." The WiffleBall does indeed form. One presumes there...

Re: EMC2 news

Part of my last post was informed by the slides. Slide 3 is an update of images Dr. Bussard used since back in the 90's, the WiffleBall. It appears to be fresh art, and has simplified the explaination (RWB showed two paths to the WiffleBall). In slide 7 we can see "Breakthrough: Wiffle-Ball&quo...

How's retirement going Aero? 'Cause you sound like a natural used rocket salesman! :wink:

Re: EMC2 news

About this matter of physicists not being good at code and software geeks not being good at physics, why would anyone believe you can't have both on a team and have them learn something about each other's craft? This is why Dr. Bussard hired Kitty King and later Loren Jameson to work with him prior ...

Re: Skynet is coming.

I had to look up "Time of Flight camera". What a stunning concept ... every pixel does rangefinding!

Early self-driving cars had a couple of LIDAR units stuck on high corners. $30k a pop, and just gave a 2D picture.

Skynet indeed! Every Terminator needs a pair of these.

Re: SpaceX News

Looks like SpaceX got ten Iridium satellites up in one shot last night, and then stuck the barge landing. The judges deducted 0.1 points for not being exactly dead center in the inner circle, but awarded a high degree of difficulty in launching 10 satellites successfully, a barge landing, and becaus...

Re: Skynet is coming.

" It is worth a mention that the US military entered WWII with some sectors of its tech in really backwards condition " And some was superlative. The "any gun within range" artillery directing system was a terrible shock to the Germans, as was later the radar fuzed air-burst amm...

Re: Skynet is coming.

We used to own a condo in Myrtle Beach. We rented it out in summer, so the only time I ever got to visit the NC was in cooler weather. This should also mean less crowds, highly conducive to exploring on your own. We've toured the Alabama, the Missouri, and the Wisconsin, plus an aircraft carrier or ...
