Comment: Limited 3D, limited scaling (Score 4, Informative) 42

It is excellent tech but they can't stack the cells indefinitely. The approach uses pillars of cells with no cross wiring. All the control circuitry is in one plane at the bottom. This makes it cheap because they only have to mask and etch once: all the way down to the planer circuitry on the bottom. The downside is you can only go so high before the control circuitry can no longer detect the signal from the top layers They could add another layer of control circuitry but the principle cost of making a chip is the masking and etching so it may be just as cheap (and definitely easier) to just make two chips.

All the doom-n-gloomers miss what's really going on. AI isn't taking over - we're redesigning ourselves. Once viable non-biological emulation of our existing mind becomes possible, people will choose to migrate themselves onto that. Humans will upgrade. The end of biology will be a matter of consumer preference.

Strong AI and uploading are nearly orthogonal. Some possibilities:

1) Strong AI happens but no practical method of extracting a mind from a biological brain is found. The only machine intelligences are purely artificial.
2) Strong AI and a practical method of extracting a mind from a biological brain is found but technologies are incompatible. At best, the machine can emulate a biological mind very slowly.
3) A practical method of uploading a human intelligence onto a machine is found but strong AI is not solved. The only machine hosted intelligences are uploads.
4) Strong AI is not solved. Uploading is available but uploads are slower or otherwise inferior to running on a biological brain.
5) Neither strong AI or uploading are solved. The discussion continues until the end of days.

The REAL problem is twofile: (1) that we are no longer creating new, higher-paying jobs to replace those that were automated away, and (2) that the benefits of increased productivity per worker haven't been shared by the workers for 40 years.

The REAL problem is that you can't imagine what you could possibly ever do without a 'job'.

That's a secondary problem. Most people worry about how they would *survive* without the paycheck that comes from having a job.

Dear Slashdot, I have a 1 and a 3 and I need add them and make 5. How can I add them together to get 5? Please don't tell me 1+3=4. I need it to be 5.

There's zero fucking reason to put an HTPC in a crawl space. Get a small machine and stick it by/behind the TV. Minimal power / video / network cabling, minimal worry of dust / moisture / temperature, minimal issues with connecting to a keyboard / mouse / remote, minimal issues with access when it needs to be physically powered on off (and it will), minimal cost, etc. They even have cases small enough that you can mount them on the TV's VESA mounting holes.

Oh, I can think of a reason: One or both members of the household has a strong sense of aesthetics and do not want anything resembling a computer in the living room.

In ran into this once with the girlfriend of the guy who owned the house I was living in. I was arranging speakers next to a big CRT TV. I noticed that the speakers interfered with the CRT, causing quite noticeable color distortion strong near the side and fading toward the center. I suggested moving the speakers out a foot as I found that this was enough to cure the distortion.

Her: "No, it looks better the other way"
Me: "But it doesn't work well"
Her: "keep the speakers close"

I gave up. Not my house and she watched the TV much more than I did.

The current current situation is probably considered acceptable only because the machine than drives it is a laptop and it gets packed away when not in use.

wrong. a simple parity check can only correct one bit, most ECC memory is quite capable of multi bit flip correction through interleaving especially with neighbouring bits.

Parity can not correct any bits. It only detects single bit errors. While many ECC codes exist, the Hamming code overwhelmingly used in computer memories can correct one bit in a 64-bit word and detect two bit errors.

it's just a polysaccharide with alcohol in it, the particular one they use can absorb 60% its weight in alcohol

So, how is this helpful for anything? If you want concentrated alcohol just do that. Sure, it's still liquid but it weighs 40% less than this powder and lightweight containment of liquids is a solved problem.

Sure, it might not taste good but reports are that the powder taste pretty bad too and involves otherwise unnecessary ingestion of questionable chemicals.

It looks to me like the only purpose is to make an end-run around liquor control laws. I'm sure the manufacturers banked on not paying the usual alcohol taxes either.

Ideally, you use congnitive radio and never grant exclusive use, only priority. If the priority user fails to show for X amount of time, another user can request the allocation as priority user. Cognitive radio implies a fair bit of spectral flexibility so they should be able to adapt to whatever is available fairly close to deployment time.

+ - Russian opposition leader Boris Nemtsov shot dead in Moscow.

An anonymous reader writes "BBC News Reports

An unidentified attacker shot Mr Nemtsov four times in central Moscow, a source in the law enforcement bodies told Russia's Interfax news agency. He was shot near the Kremlin while walking with a woman, according to Russian-language news website Meduza. "Several people" had got out of a car and shot him, it added. Mr Nemtsov, 55, served as first deputy prime minister under the late President Boris Yeltsin in the 1990s.

Meanwhile, various sources report a massive gathering of protestors at the site of the shooting."

These folks has some busted RAM, but all is good because it's ECC

If it was all good, they would not stutter. No, it looks like some important wiring is missing. Their brains have implemented a work-around that mostly does the job but is not a complete solution. There are conditions it does not handle well. A retraining program seems to help but it not clear if the wiring fault is being fixed or if they are just gaining an improved ability to avoid the problem cases.

1) The blight "breathes nitrogen" and destroys all plants one crop species at a time.
2) A society which never got much further than we are today and whose technological civilization is falling apart is able to mount a crewed mission to wormhole near Saturn?
3) Several habitable worlds very close to a black hole. Why are there any? Where are the host star(s)?
4) The future utopia never went back to the black hole worlds but got along fine anyway. So what was the point?

With all the sloppy science, technology, and plotting going on, does it really matter if the visuals of the worm whole traversal or subtly wrong, exactly right, or just pure bologna?

Nobody's gonna believe that computers are intelligent until they start coming in late and lying about it.
