Submission + - 'Shadow biosphere' might be hiding strange life right under our noses (sciencemag.org)

sciencehabit writes: If we came across alien life, would we even know it was alive? All known life on Earth fits a particular mold, but life from other planets break might free from that mold, making it difficult for us to identify. We could even be oblivious to unfamiliar forms of life right under our noses. Scientists are now proposing some new things we should look for when it comes to identifying life in a “shadow biosphere”—an undiscovered group of living things with biochemistry different from what we’re used to.

I admit I haven't looked into it deeply yet, but I suspect it may be able to switch in and out of this mode. Else, you'd have to precompile every thing you run in encrypted form and not be able to use any shared libraries. The binaries would be pretty tubby and performance would suck for the reasons you give.

Run the license checks and some of the key code that's not very compute intensive in the encrypted space, and then shift context to run things you call to do the heavy work in unencrypted space.

I don't know if there is journalistic purpose in this. I only know what I feel about it. I've not watched it (or there other videos) and have no desire to.

I've seen people dying and badly injured before in real life as well as video. I'm not very squeamish about it, but it's unpleasant.

ISIS desperately wanted people to see this and have it burned into their memory. I have no desire to help them get something they want. The couple of stills I saw from it simply confirmed my opinion of them.

Beyond that, I have neither time nor memory neurons for either them or their "snuff" videos.

It's all clean sharp and black and white in your universe.

So, to be safe from moral hazard, maybe he should just not do math. Nobody should do math. Because it might end up being used for a bad end or be paid for by the "wrong" people.

I'll leave the moral purity to you, religious fundies, and other true believers.

It may be morally uplifting, but, sharing the world with you is going to a little chilly, because even fire has been used as a weapon.

I was in ABQ in the 90s, and they had things like the Airborne Laser 747 come through, an Antonov AN 124 delivering a Topaz space reactor (had to close Gibson Ave when it departed for worry about the jet wash being over the barriers), etc.

A lot of the interesting things didn't look all that odd unless you knew what to look for, like extra sensor ports added to them and such (Aviation Week was sometimes a good guide to those). The trestle was already closed, so they weren't getting them for EMP testing so much. Phillips Lab still got a lot of one off planes coming through for things related to R and D.

The Balloon Fiesta mass ascensions are still one of the most amazing things I've seen. I-25 was a dangerous place to be driving when that happened. everyone was looking at the balloons and not the road.
