bad_alloc··on Organisms might be quantum machines
Tha's what Roger Penrose argued in "Shadows of the Mind" where he theorizes about quantum effects in the human brain and how they might give rise to conciousness [1]. There's some criticism about it, because the brain is pretty warm and decoherence should disturb all quantum states so much taht they become unusable, but it is still a research topic if "warm" quantum states can exist.

1) Power feels awesome. You'll use your power to get more power because it feels so good to see those you hate having to bow to you.

2) Educated people are dangerous as they will almost certainly doubt the legitimacy of your rule and more importantly have the ability to plot against you. Hence they must go.

I applaud your thinking, as it is empathic towards your hypothetical subjects :) However people like Erodogan do not think at such a level. Assume a primitive (but not dumb) egocentric world view in dictators. If they had empathy, they wouldn't have been able to fight to get to where they are now.

bad_alloc··on AI will create 'useless class' of humans
So far we've automated physical tasks. It was possible to go into intellectual jobs as an alternative avenue, since automating that wasn't possible. However now we're automating mental work. Humans can currently go into jobs requiring higher education or creativity but 1) this won't work for everybody and 2) this is not a new avenue outside of the reach of automatization. The machines have a good chance of catching, especially since a lot of those humans moving into more specialized jobs will be tasked with making better machines, which in turn endangers more jobs.

bad_alloc··on Tesla crash after flying 82 feet in the air shows importance of a crumple zone
> ... a 18-year old took her father’s Tesla Model S ...

That hints the car might have been taken without the parents knowledge. Then again this happened near München, so it might have been some overaffluent teens in their usual ride paid by daddy. It's not uncommon to see rich college students in a Porsche around there.

Juraschuleaufnahmeprüfungsvoraussetzungen btw. Although nobody would actually say that. More like "Aufnahmeprüfungskriterien für die juristische Fakultät".
bad_alloc··on DOD officials say autonomous killing machines deserve a look
Then again, the printer is just not working. It's not randomly printing things you don't want. In the same sense, a broken autonomous tank would just stop dead in its tracks instead of suddenly killing everything that moves. Those failure modes have always been very rare.

I'd argue that China, Russia and the US have already passed this point w.r.t. nucelar weapons: Every side is sufficiently armed so that a war between any of them cannot be won. As soon as you start winning in a conventional scenario the other side might as well use nuclear weapons, just to ensure you'll lose too. In short a war between nuclear powers makes no sense, since the "victory condition" has been removed.

I'd assume that this is the same in asymmetric conflicts: If you are fighting a guerilla war, you "win" when you kill some of your enemies troops and demoralize them. However if enemy sends only machines, then cannot win as long as the enemy is capable of producing more of these autonomous weapons than you can destroy. As you've said the cost savings do enable that. Hence the guerilla side also loses its victory condition. This is a scenario I'd actually like to see, since it might put an effective end to the kind of fighting we've seen in the middle east.

Your argument is of course correct when we consider two countries which are both capable of producing such weapons and neither side has a nuclear weapon. Saudi-Arabia and Iran are candidates which could probably fall into this kind of an arms race and that would indeed make the situation there even worse.

bad_alloc··on DOD officials say autonomous killing machines deserve a look
Just playing the devil's advocate here:

* No soldiers of the side deploying armed drones need to be in danger.

* Robots do not act cruelly unless specifically instructed. Humans do have a pretty bad record of unnecessary cruelty due to racism, boredom, intoxication etc.

* If you log all descision making processes, you can justify each action taken. It's like bodycams for police officers. If you'd make all logs public after the war it would be possible to identify war crimes and who gave the order (unlike now).

* Nothing requires a machine to use lethal force all the time. Systems which have the primary purpose of capturing combattants can be considered when there's no risk of losing one of your own soldiers.

* Your robots priority doesn't have to be self-preservation (unlike a human soldier). When in doubt, don't shoot and analyze the situation.

All in all, if the military would use these autonomous killing machines with the intent of minimizing covilian casualties, would this not be an improvement over the current state of warfare? Of course it won't make war per se less likely, but not using these machines doesn't either. So why not use them?

bad_alloc··on New finding may explain heat loss in fusion reactors
You are right in saying that Thorium reactors are receiving too little attention. However due to their breeder nature they also produce nuclear waste which needs to be stored for hundreds of years. The main advantage of fusion is that you only get light radioactive istotopes of Helium or Lithium which decay within hours or days. The reactor walls are activated through neutron capture, which renders these highly radioactive for 50 to 100 years [1]. In comparison to fission reactors, that's not very long.

I disagree: You can impress most "Generation Z" kids by introducing them to Ctrl + F in the browser. Using technology without knowing how it functions seems pretty prelevant.

bad_alloc··on Ask HN: How could I have a summer internship with a tech startup
> I'm not American.

Apply for visas early. Make sure you don't apply to a company involved in aerospace or military projects, as these often only employ US citizens and protected individuals. That bit me when I tried.

bad_alloc··on Rapid recovery from major depression using magnesium treatment (2006)
A quick search on Google Scholar reveals more studies confirming this: [1] [2] [3]. It might be worth trying out, since it seems to be pretty hard to overdose on magnesium unless you have kidney failure. [4]

bad_alloc··on Biggest mystery in mathematics in limbo after cryptic meeting
> I mean people are really, really good at communicating.

On my experience, people are usually really bad at communicating. It requires additional effort to imagine what information might be required for somebody else to follow your train of thought. Think of code documentation: What the original author percieves as obvious is cryptic to somebody else because context has been omitted for the sake of brevity. The author needs to invest a lot of time to actually dump his entire mindstate into documentation. Even if he does make an effort, not everybody is a good writer. If he doesn't care about others understanding his stuff (which also seems to be the case with Mochizuki) it gets even worse.

Also remember that Mochizuki basically worked alone on his stuff for 20 odd years. He built his own world to work in and it's just as hard for collegues to catch up to his level in that world as it is for e.g. non-programmers to understand programming (which takes years).

bad_alloc··on AKATSUKI preparing for orbital insertion around Venus
Problems with Venus:

* Acid atmosphere and extreme winds

* No easy surface access -> No on-site resource extraction

* No magnetic field -> more radiation

* Larger delta-V requirement for a round trip

* We have no launch systems built for a launch while suspendend in the atmosphere

* Low water content

* Much less signs that suggest previous habitability (hence Mars is more interesting)

This defeats regular face detection but you are now literally wearing a big, glowing sign that says "this individual is hiding his/her face!".
bad_alloc··on How did science come to speak only English?
I'm not sure it's that, because German adapts to new concepts easily by simply concatenating old ones. The most popular example is probably "Doppelkupplungsgetriebe", which stands for dual-clutch transmission. This means you can get along with a few primitives but on the other hand you get some obscenely long words. You find a lot of those in the legal sector, like "Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz" which was the name of an actual law controlling how beef is labeled.
bad_alloc··on Voxelvoid – A retro arcade shooter
A pixel is a unit on a 2D grid and a voxel is the counterpart in 3D. What makes voxels interesting is that you can build worlds out of them the palyer can shape, like Minecraft. The smaller your voxels, the better your world might be. The main benefit of voxels over terrain made of textured polygons is that deformation looks better in voxels, because the terrain isn't warping but actually disappearing.
bad_alloc··on SpaceX Will Announce Micro-Satellites for Low Cost Internet Within Three Months
Property rights still apply in space: Any vehicle you launch is yours and you can be held accountable for damage you do to somebody else's vehicle. Proving that somebody killed your satellite on purpose should be pretty difficult though.
bad_alloc··on SpaceX Will Announce Micro-Satellites for Low Cost Internet Within Three Months
Nations have no jurisdiction over outer space. Hence no nation can prohibit an orbit over its landmass. However the definition of where space begins is not precisely defined [1].

bad_alloc··on Stephen Hawking: AI, Potentially the Worst Thing to Happen to Humanity
I recommend reading "Shadows of the Mind" by Roger Penrose. In that book he argues that strong artificial intelligence isn't achievable on classical computers, since the human brain seems to have the ability to do quantum computing in certain molecular structures. These processes probably can't be simulated efectively. So AI in today's computers probably won't work at all (although quantum computers or artificial neural networks might).

bad_alloc··on The less Americans know about Ukraine’s location, the more they want ...
How did they ask people to locate Ukraine? Some of these points look like somebody accidentally clicked on a random spot of a map. For example, the dot below New Zealand is in the middle of the ocean (approx. -55.000000,176.000000). Some even located it within the US (Florida seems to be a popular guess). Have they found really misinformed people or is this noise in the data?
bad_alloc··on Scientists Say Their Giant Laser Has Produced Nuclear Fusion
All research into nuclear energy can be used for nuclear weapons. A nuclear reactor is just a well-cooled bomb that isn't supposed to explode violently (so to speak).
