Turning Scientists into Politicians

I used to enjoy using names from The Wheel of Time series, the forsaken especially. I’ll admit to spending a bit more time than was practical on the endeavor, but I think it sort of helped me “bond” and care more about them?

Ah, it was fun at any rate. I miss you, Lanfear!

This is a great example of what people here hate, while not hating the underlying technology. In the midst of a ludicrous series of ICO scams and proliferation of get-rich-quick coins, it’s very clearly false. For those of us who like our Libertarianism grounded in reality, the fantastical, counterfactual version peddled in cryptocurrency circles is almost offensive.

Or they recognize that for a human and generations of their descendants, 30,000 or 300 years doesn’t change anything for them. Either way it’s longer than the US has been a country for one metric. Both cases require similar solutions, long-term containment, and so both run into the same political inertia fielded by NIMBYism.

To claim otherwise is, as you would have it, lying.

More importantly, both are solved issues from a purely technical standpoint, it’s just that everyone wants someone else to deal with it. As a bonus, we can actually use fission to produce energy, right now. There’s no issue of, “it will be great when...” grid storage is solved along with intermittency for renewables. There’s no, “it will be great when...” fusion is producing energy rather than heavily parasitizing from the grid. There’s no waiting until we’re completely screwed by climate change effects.

And if we’re willing to deal with that waste, then we already have a viable source of atomic energy from fission! The future is whenever we decide to deal with the problem instead of leaving it pools or casks to solve itself.

@csallen: Be willing to actually dispose of it. We need to commit the money and political will to set up a single disposal site. Right now it’s a NIMBY nightmare so we get the worst outcome.

The numbers so far, including human intervention rates do not support the claim that autonomy beats humans. With a limited dataset, the suggestion is very much in the other direction. These vehicles may someday be better than us, but “someday” isn’t today. In particular I think Uber had a human intervention on avg every 13mi.

Edit: I’d love to hear a counterpoint, although of course I accept that’s not required. Like the discussion about fusion, people seem to argue from a point in the future when all of the problems and limitations of today are gone. Let’s try arguing from what’s possible now instead.

Unsolved problems for fusion as powerplant:

-Sputtering of shielding and every other part of the reactor from fast neutrons. If your reactor is becoming brittle as it’s in operation, and requires constant maintenance, it won’t be operating enough to be cost effective.

-Breeding blankets. If we’re not breeding tritium in the blanket (and no one has been able to sustain a reaction that way yet) then we’re just using fission a lot. Expense becomes an issue, as does radiological issues.

-The plasma diverter is very much an unsolved problem. I can get into more detail here, but in short this is the part of the reactor that “skims” some of the hot plasma off to do the work. The dynamics of very hot, magnetically constrained plasmas still escapes us, and when you throw a rock into that stream, the complexity increases. Current divertes wouldn’t last a day in an operating plant. Disassembling your whole plant every day and reassembling it is a non-starter.

-Containment of plasma at sufficient energies is still something measured in seconds, or fractions of seconds. The usual metaphor is trying to uniformly squeeze a balloon; it will just “squirt” out. For s research reactor a second or two of fusion is an achievement. For power generation it’s nothing.

-Neutron activation of otherwise inert materials means you’re going to have serious radioactive waste. It’s unclear just how dirty D-T fusion would be from soup to nuts, but “pretty dirty” seems like a good bet.

-Tritium penetration.

-Most of the energy produced is in the form of neutrons, and we don’t know how to use that as a source of power. Those neutrons, in addition to destroying the reactor itself and activating materials, represent a loss.

-What we really need is aneutronic fusion through alternative cycles to D-T, like p-p, but that’s a much hotter plasma and no one has a clue how to make it work yet.

-Coolant for a constantly running reactor is a boring, but unsolved problem.

There’s more, but these are the ones most poeple on HN probably are aware of when they dismiss this article.

If you’re in the US I’d suggest calling 1-800-273-TALK

If you’re in the UK try +44 (0) 8457 90 90 90

If you’re in AU try 08 93 81 5555

If you’re somewhere else I’ll find a number for you if you’d like. No one is going to judge you for calling, you’re not going to be wasting anyone’s time. @pedalpete is giving good advice too.

In the moments before the collision, which occurred at 9:27 a.m. on Friday, March 23rd, Autopilot was engaged...

The rest may be true, may be germane, or may not be. The only part that matters to me until the results of the NTSB investigation is made public, is that the autopilot did this.

Bullshit. This is an ICO off the back of people’s desire to fight cancer. No FDA approval, no actual system, no substance, just GLIA “utility” tokens. If they want to defend their approach with something substantial, I’ll retract the “bullshit,” but this looks like the usual ICO scam. I took the liberty of filling out complaints with the SEC, FDA, and FTC yesterday and hopefully they can get some real answers.

Other than repeating phrases like AI, Deep Learning, and Blockchain, it’s really thin on how a public ledger is going to achieve any of this.

Therefore, GliaLab is proud to announce that we are building GliaBase, a global diagnostic healthcare platform utilizing AI and blockchain technology to provide users with universal and safe remote access to next-gen diagnostic tools and advice. Essentially, it is a platform powered by deep learning algorithms where users have access to top-tier diagnostic tools and healthcare information related to different diseases.

Yeeeaaaaah. How? There’s a lot of back-patting, some “imagine a world...” and just a dash of “Patients will... doctors will...” and zero specifics. Weasel words like “essentially” in front of a pat and low-content description of the actual platform also raises alarm bells for me.

This reeks.

Went to their site, and it seems the magic ingredient is that this is another ICO, complete with flashy splash page, and all of the usual red flags. They’re selling 30,000,000 GLIA (Gliatokens) which they assure you is a utility token. For something they haven’t built yet. The SEC is not going to be amused.

That fucked up world is called the world, and the world as it’s always been. None of us has to like that, and we can try to change it, but it’s still the world. Ignoring reality in favor of what we want to be true is magical thinking.

Bram Cohen didn’t go on Hacker News and invalidate every safe harbor a defense counsel needs, either. Just to be clear, you’ve said, in writing, on behalf of your company, that you are aware of illegal activity happening on your network, that you’re okay with it, and that you monitor the network on which illegal activity is taking place and have determined the legality thereof (enough to know a minority is illegal).

Yeah, he’s going to prison, but that doesn’t mean he’s wrong about the potential value of his platform, and it doesn’t mean his motives aren’t good. It probably does mean that idealism is a shitty defense in court though.

If you need whistleblowers to be saints, you’re going to have a bad time. The guy who blows the whistle on bad practices has to have a lot of access, which means he’s probably culpable. That doesn’t make their information less accurate or valuable though. The world of informants is a world of compromised people, but still a world worth engaging with.

What we really need is an energetically advantageous way to produce high energy neutral particle beams. That would start to look more like the ray guns of science fiction than lasers ever will. It’s not just the weather either, when you hit a target that has a bit of appropriate ablative armor, you’ll be dealing with another source of bloom.

LIPC tech is good too, and might be closer than you’d think. You can exploit the interaction of ultrashort laser pulses to create and modulate plasma, and then do neat things like send a bunch of volts down the channel.

Blindness, 2nd and then 3rd degree burns. Think of it more like a heat ray, and you get the idea. Human heads don’t have the option of countermeasures though, such as ablative costing which dramatically increase blooming, while insulating the target. You need more than 100kw to either punch through that, or take advantage of non-linear effects.

The worst router I’ve ever seen was a D-Link. I was in a position where I had to provide support for it, and in the end I gave up and bought them an ASUS with my own money. It ended up being worth it, just in terms of time and aggravation saved. The software and firmware on the D-Link were garbage, and so was the actual build.

If your solution requires technology which isn’t even close to being practical, then you’re just going on about sci-fi. That’s very interesting, and with a few exceptions sci-fi usually gets it wrong.
