I thought the tank era had passed us. Once that tank fires a single shot, its location is revealed and an artillery or air strike can be ordered against its approximate location.

We are well in the era of air superiority and moving ever closer to the era of drones. Tanks are relevant for the previous wars only.

So something like lightly armored rocket artillery with a screen of antipersonnel/reconnaissance drones that could paint targets for guided rockets.

Not only that. The drones themselves could act as munitions. They could clamp themselves onto something like a main battle tank cannon and set off a shaped charge.

This might work well until you need to take enemy air force into account.

Make the drones small enough, and make them fly low enough, and it won't be as much of an issue. Also, this is why you have your own air force and surface to air missiles.

Peltiers are notoriously inefficient. Hideously. Reasonable numbers are in the 10% range. So in order to remove say 5kW of heat from the skin (1.5 tons of refrigeration) which is pretty conservative would require say 50kW of power. Most of which would end up as heat in the metal of the structure of the tank.

If you figure the chassis and armor are say, 50 tons, and steel, you can do a little math to figure out how quickly it would heat up. 50 tons is 50,000 kg and the specific heat of steel is about 0.5kJ/kgK. We're putting heat into the chassis at the rate of 50kJ/sec and things cancel out pretty nicely. You'd heat it up at about half a degree C per second, or about one degree F per second.

In the best possible scenario you're talking about no more than two minutes worth of stealth (perhaps only 30 seconds in reality) and that's with the tank not moving and only idling its engine, just enough to produce the necessary 50kW. It's a neat trick, but I'm not sure it's worth writing home about.
Only one problem. The enemy can't surrender to an Aircraft. So even with all the air superiority, you still need the Cavalry.

So long as you need troops on the ground to hold territory, you will need mobile protection against machine guns and artillery. Once you have those, then you also will need something that takes the role of a tank. However, maybe technology will take us past the era of 70 ton behemoths armed with a huge cannon.

I have a quite different proposal. I may or may not be serious about this--I have not yet decided. Countries with problems with poachers taking elephants from game preserves should do this:

1. Legitimate parties entering the preserves must register and receive a GPS tracking device which reports their position in real time to the park management.

2. Sell poacher licenses to hunters. By "poacher license", I do not mean a license to poach. I mean a license to hunt poachers.

3. A hunter with a poacher license must call in any targets they are considering to the park management, which will check their position against the legitimate parties on the preserve, so that the hunters can be sure they are not targeting researchers, tourists, hunters of non-protected animals, and so on.

4. Once confirmed as not legitimately in the park, the hunters may treat the poachers as if they were any other game animal and kill them and take trophies. If they are going to kill them, they must do so promptly. They cannot capture them and abuse them first. We are not trying to be inhumane here.

5. Poacher licenses should be expensive, with the cost going to help the animals. I would be surprised if there were not plenty of wealthy people who would pay millions for a license.

6. Hunting poachers is at your own risk. Man is the deadliest animal.

Of course, there might be unintended consequences. For instance, if someone has the disposable income to buy a poacher license, they would be a good kidnapping target. A kidnap gang might pose as poachers to try to lure poacher hunters for kidnapping.

Probably too many problems with international treaties and other legal issues to actually do this. It could make an interesting setting for a movie or a TV series, though.

I believe he said "existential". An existential threat is something that threatens the existence of humanity.

A good AI would provide world peace. It could take over human governments, work out conflict, stop destructive behavior etc.

>The AI it describes is not logical, there is no logical reason for AI to want to compete with other forms of life, unless it is programmed to do so.

That is the problem. An AI programmed with almost any goal, will try to capture as much resources as possible to complete that goal. E.g trying to capture as much energy from the stars as possible, to preserve itself as long as possible against heat death. Or trying to build as much redundancy as possible to prevent against disasters. Or trying to build as much computing power as possible to solve difficult problems.
of course it is else it wouldn't make sense now would it. Synonyms don't have the same connotations.

"if you don't know how to reproduce a result it's not science."

Astronomy is one of many sciences which can never reproduce its results in the way you're talking about. Do you not consider astronomy to be a science?

In any case, this paper was looking for counter-examples. If found, then they would be all the evidence that's needed. The method to compute the counter-examples is nice, but irrelevant.
I don't think they're really the same thing. Arithmetic precedence comes from the meaning of the operators themselves while the other layers of grammatical precedence simply provide consistent structure. The reason this is a problem when the operators can overload is that the structural aspects of the operators may no longer apply to their meaning. See for example the iostream operators << and >> in C++, which actually have a very awkward precedence that forces you to parenthesize things in unexpected ways sometimes.

> You seem to get this, because you said you wouldn't mind so much if it was being sold as "an intro" instead of a "silver bullet." While it's technically true, it would probably do more harm than good. Seven minutes is something that just about everyone, including very unhealthy people, feel like they can achieve. Which do you think is more likely to get people interested?

I heavily disagree with this. People run these programs and do them as written and don't dig any deeper. They don't achieve results, and that leads them to develop (completely warranted) distrust for the fitness industry. This makes them feel like exercise only works for some people, and they must not be one of those people. People feel like their weight is genuinely uncontrollable.

On the other hand, a realistic approach gives them the tools they need when they are ready by starting out easy and gradually progressing.

Yes, milling to 0.0001in tolerance is rare, although possible on some machines. 0.001in is not unusual, though. This 3D printer, from the pictures, seems to be delivering about 0.2in. That's worse than sand casting. Still worse, some of the errors are in the void direction, undersize. If this thing consistently produced a good solid metal blank, ready for finish machining, it could substitute for having a foundry for small jobs. But it's not even that good.

There are very good, but expensive 3D printers that print excellent metal parts. Check out Space-X's 3D printed rocket engine for the new Dragon spacecraft. Shapeways can now do small steel parts for $10 + $5/cc with reasonable tolerances. 3D printing of metal works now. This welder thing, not so much.

That's not any theory I've heard of. Programs generally have you doing the same exercises repeatedly. Variations are not usually intra-program substitutes, and "slight variations" as substitutes are an anti-pattern. "Many muscles" also has nothing to do with it either--most leg exercises put the largest component of stress on the glutes, which are one big muscle body. On the other hand, the back is a whole lot of different muscles but I don't think very many people do 3 back days a week.

In particular, the GP was talking about Stronglifts, which has you doing the same old back squats 3 times a week, variations strongly discouraged.

What exactly did you search for? I searched for just "tablet," and the results aren't terrible. Near the very top it's mostly extremely cheap Chinese Android tablets, and there's a few anomalous prices in there, like $99,999.99, but the Samsung Galaxy Tabs are in the first two rows as well. I don't keep up on the Android tablet market, so I don't know what I should expect to see.

But there are also useful filters at the top and left, which made it easy for me to find the few name brand tablets I'm aware of.
Believe it. I'm not strong though. Maybe when I'm repping 300 it'll be hard to do it three times a week. At 245 it is not a big problem.

Part of the way that manufacturers convince customers that counterfeit chips are unacceptable is by pointing to a higher rate of glitches and failures.

... and? Tanks don't have to rely on stealth to be effective. Air strikes are only reliable if you have some degree of air superiority. And tanks can move - depending on what kind of artillery you're facing, they might not be able to chase a moving target.

There were tank-on-tank battles in the US's invasion of Iraq, so they're not that out-of-date. Plus, while there aren't going to many tank-on-tank battles, tanks are an important component of combined arms tactics - you need infantry to take urban areas, and infantry is more effective with armoured support.

I have never found a drawer full of "odds and ends" stressful: I can see how you might, but from my perspective seeing that drawer is satisfying and soothing, as it means that I'm more likely to have whatever it is that I might need. The tax is only in "whether or not you can find it", which some people have also cited as being stressful, especially when you are trying to find something you know you own but are unable to do so; but, once you realize that throwing something away means you can't find it, it becomes acceptable to sometimes fail to find something and end up with two of them. The secret is just to make certain that the stuff that you don't use often is the stuff most likely to be lost. (Of course, if you can find someone else who will find these things valuable, I'm all for giving the objects away.)

Oh I agree with that. Targetted versus en masse surveillance, though, as the cost of personnel and equipment would have to scale with the number of targets to deanonymize.

Everyone's data gets sucked up as the default, but with Tor - I think they Snowden docs showed they could only get about 1/4 with automation. I do not remember the exact percentage.

The combination of CALEA, Stored Communications Act, and Patriot Act under the Third Party Doctrine mean the system stores and processes our data by default, over a sliding window. (IIRC there were some Snowden programs that had windows of around 5 years?)

With Tor you increase the cost to taxpayers a little and decrease the chances (especially with good cyber hygiene) that you'll give everything. If you use a cell phone you give your exact time and place 24/7. Even local police have access to these cell phone tracking databases. You can't Tor a cell phone.

Tor isn't really a good answer to the system. But if you need privacy, there's a corner in Tor.
> They failed to give a example of how this harmed children ... I just don't really understand what we are trying to protect and what the big deal is.

A few thoughts about this argument, which many people bring up:

1) Many people value their privacy; it might not be universal (though I think everyone does to some degree) but it's widespread and has been enshrined in law and custom across many (I suspect all) cultures.

2) Information is power. I don't have to explain why on HN (I hope). People who control information about you have power over you, to varying degree. Information also has value and should not be taken without consent (which is financial harm, arguably).

3) Some argue that if loss of privacy results in no physical or financial harm then it results in no harm. If you think through this argument, clearly there are other universally recognized kinds of harm. For example, the following might result in no physical or financial harm: Sexual assault, kidnapping, home invasion, theft (if the assets are returned soon), if I caused your spouse to divorce you or family to disown you, installation of malware on your computer, etc.

I think the question of the harm in an invasion of privacy is an interesting and valuable philosophical one to consider, but I feel it's a bit disingenuous to propose seriously that privacy has no value.
The Fourier transform is the map between sound waves and music as written on a staff.

I have never heard of that. To my understanding, the important elements are:

- Recovery doesn't take seven days.
- Squats target the biggest muscles.
- The biggest muscles produce the most testosterone, enabling you to make gains in other muscle groups more easily.

Given those and the constraints of safety and putting up the most weight you can for a decent amount of volume, you want to squat as often as possible. Not just for your legs, but because it enables you to do more elsewhere.

I don't think Rubin was forced out because he was judged a failure. There's just no proof of that.

Android had succeeded and under Rubin the team was doing great - except that there was a lack of tighter integration between Google's other properties and Android - Chrome for instance took too long to get on Android and become good. Same with other apps. As is evident now from how much progress Hangouts, Chrome amd ChromeOS have made under Sundar - he was well poised to lead a team that would have all these under one umbrella and Rubin apparently had other interests. So it worked out well for everyone.
