Child Thought To Be Cured of HIV Relapses, Tests Positive Again

gregor-e Re:I hate to imagine it (126 comments)

As wikipedia assures us (emphasis added):

A retrovirus is a single-stranded RNA virus that stores its nucleic acid in the form of an mRNA genome (including the 5' cap and 3' PolyA tail) and targets a host cell as an obligate parasite. Once inside the host cell cytoplasm the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backwards). This new DNA is then incorporated into the host cell genome by an integrase enzyme, at which point the retroviral DNA is referred to as a provirus. The host cell then treats the viral DNA as part of its own genome, translating and transcribing the viral genes along with the cell's own genes, producing the proteins required to assemble new copies of the virus. It is difficult to detect the virus until it has infected the host. At that point the infection will persist indefinitely.

Normal Humans Effectively Excluded From Developing Software

gregor-e Re:Cry Me A River (608 comments)

Whining about how hard the tools are to use and how, if only the tools could be made as simple as a hammer then everyone could program, is as naive as suggesting that if word processors were as simple as pencils, anyone could write poetry.

What these utopian visions of programmatic democracy all lack is any notion that attacks the essential complexity of the problems being solved by code. Problems that have, if anything, grown more complex with increasing memory and CPU power. All the forays into "graphical programming" or other tools to take the programminess out of programming have shown that it doesn't matter whether you're expressing a solution in text or little icons connected by arrows - the essential complexity of the problem remains. The only way we're going to democratize programming is if AI gets to the point where the thoughtwork of breaking down the essential complexity of problems can be offloaded to some other intelligence.

Happy Software Developers Solve Problems Better

gregor-e Management is hard (121 comments)

This is one more tricky aspect of managing software or any other creative/analytic project. You can start with the smartest, happiest people in the world, only to have your schedule blown because one of them is going through a messy divorce or a loved one gets cancer. The bad vibes can drag a whole team down. I forsee a huge market in happy pepper-upper pills for programmers. Oh, wait. That's what coffee is for.

Cambridge Team Breaks Superconductor World Record

gregor-e Powering down? (73 comments)

How did they power down that experiment? If they let the temperature rise until it drops out of superconductivity, it'd explode. Or did they just load magnetic field until it burst and chalked up the maximum as a new record? That's almost enough to make magnetic munitions - shells that explode on impact and also pack an EMP wallop.

A Physicist Says He Can Tornado-Proof the Midwest With 1,000-Foot Walls

gregor-e Re:stupid comparison (501 comments)

So we don't build it out of concrete. The Yellowstone supervolcano will eventually blow and wipe out most of civilization sometime in the next few millennia, unless we do something about it. We can't simply drill a hole to the top of the magma, since that would set it off. What we have to do is tunnel down deep, to the lower part of the magma column, where the density is much higher and the pressure much lower. From there, we can allow the magma column to bleed off pressure gradually, providing us with a constant stream of incandescent magma that can be used for whatever we like. Then all we'd have to do is come up with a high-temperature insulated conveyor belt to transfer all the fresh magma to wherever the current end of the casting is. We could build 1000-foot walls, cast castles, create huge canals or reservoirs, whatever we like. So long as we keep coming up with good uses for a never-ending stream of white-hot magma, we're set.

Tech Workforce Diversity At Facebook Similar To Google And Yahoo

Finding enough talent is getting nearly impossible now. As an employee of an up-and-coming Silicon Valley startup, let me assure you - the form factor of the meat package of a prospective developer has zero influence on our decision to hire.

Are Habitable Exoplanets Bad News For Humanity?

gregor-e Re:Fermi paradox (608 comments)

Not only is space big to us, just imagine how much vaster it would be to an intelligence that thinks several million times faster that we do. Our civilization has only become 'visible' through RF radiation for about a century. That is a brief eyeblink of time on a cosmic scale. Our communication is already moving away from radio, toward optic fiber. Our intelligence is already making the leap from biological to non-biological substrates. It is not unlikely that a century from now, the bulk of intelligence in our region of space will be non-biological, and operating at several million times the speed of neurons. Such an intelligence will experience a human lifetime of contemplation in the span of an afternoon. Lightspeed lag will be very perceptible to this intelligence. Accordingly, such intelligence will wish to become as densely packed and interconnected as possible. Space, as it turns out, is filled with many variations on the theme of rocks that we are already familiar with. But to the fast, dense intelligence of the future, it will be several million-fold further away. By the time such an intelligence can fork off a chunk of itself and send it into space, even to the moon and back, several millennia of experience and evolution will have occurred. This, along with the fact that all they are likely to discover is more rocks, leads such intelligence to stay put. So the reason we don't see any advanced intelligence spreading through the universe is that shortly after they figure out computation, their communication drops RF and their intelligence implodes into a black hole of dense, tightly interconnected navel-gazing. Perhaps a literal black hole.

Ask Slashdot: How Can We Create a Culture of Secure Behavior?

gregor-e Re:Good morale, perhaps? (169 comments)

Offer a bonus and recognition to any employee whose computer doesn't get hacked by the hired pen tester. Publish tips on how to avoid being hacked. Compliance rates will soar. Also, knowing they are being targeted by an actual human translates an abstract notion of why security practice is important into something concrete.

The Amoeba That Eats Human Intestines, Cell By Cell

More Troubles For Authors of Controversial Acid-Bath Stem Cell Articles

gregor-e Re:Fraud? Try Idiot. (99 comments)

So it must be time to crank up the conspiracy theories.
Which is more (un)likely:

  1. Someone would attempt to perpetrate such a huge and obvious falsehood
  2. Vested powers, on hearing their castle is about to crumble, vigorously attempt to discredit the new theory
  3. Big money who is outside the potential profit sphere of this discovery is attempting to delay it long enough to get a slight variation patented

Sons of Anarchy Creator On Google Copyright Anarchy

gregor-e Re:Sour grapes (381 comments)

Heck, even just having a nominal annual renewal fee would revert the majority of content over to the public within a few years. Say, $50/year. If the exclusive right to sell a work isn't worth $50 to the rights-holder, having those rights obviously can't be all that motivating. It should revert to the public so anyone is free to have a go at getting whatever value they can out of it.

Sons of Anarchy Creator On Google Copyright Anarchy

gregor-e Re:Sour grapes (381 comments)

Theft is depriving someone of access to or enjoyment of something they otherwise would have had. In the example you constructed, your boss would otherwise have paid you a salary. By not doing so, your boss commits theft. Similarly, pirated content is contingent theft - if the downloader would otherwise have paid for the content being downloaded, then it is theft. That is the difference.

Amazon Hikes Prime Membership Fee

gregor-e Re:Amazon just wants to see how much they can sque (276 comments)

I just checked my account. 85 orders in 2013. Comes to $.92 shipping per order for me. Heck, even at $99/year, I'd have paid $1.13 shipping per order. The free videos are a cherry on top of that sweet savings sundae. If you are a prime member who didn't wring that savings sponge dry, then I thank you for participating in this little wealth-shifting scheme.

Ray Kurzweil Talks Google's Big Plans For Artificial Intelligence

gregor-e Re:Moron talks bullshit.... (254 comments)

We don't have to produce intelligence artificially. We can just copy an existing one. If sub-synaptic connectome mapping and neural emulation can be made precise enough to accurately emulate the functioning of an entire human brain on a substrate that operates at several million times the speed of our natural biological wetware, we can quickly instantiate a population of human intelligence replicas that can each experience a lifetime of human cognition in an afternoon. I bet they would have the time and gumption to figure out how intelligence works. Given their ability to reconfigure their substrate, such intelligence would most likely transcend anything we're capable of understanding in a very short time. Those of us marooned in meat-time would then hope to become the treasured bonsai of these recursive, exponentially expanding intelligences. All it takes is full-brain MRI resolution down to, oh, 100 nm and the ability to accurately emulate the function of interconnected cortical neurons.

Photon-transistors exchange data between photons

gregor-e gregor-e writes  |  more than 6 years ago

gregor-e (136142) writes "Scientist from the Niels Bohr Institute at University of Copenhagen and from Harvard University have come up with a way for photons to exchange data. Normally, photons pass right by each other without interacting. What these guys have done is establish a means of transferring information from one photon to another by using a single atom intermediary. This provides a step toward practical quantum computation, by allowing the signals to be purely optical in nature."
