Yeah, I guess I've never had pod coffee, I was just pointing out that if you squint a little bit, they are a machine making a sort of pour over.

I don't frequent coffee shops, but I don't think I've ever seen pour over as a choice. You can often find plastic filter holders for ~$3, so you don't need a lot of equipment to give it a try.
Airlines generally won't let you board unless you have the necessary documents to enter the destination country (e.g. a valid passport, a visa if required). In fact, countries will fine airlines for bringing passengers without the correct documents.

The problem with these kind of unusual scientific results is often the experiment itself, not the results. It starts as "we do X, and it has a result of Z, and that makes no sense." Someone usually figures out that it's really "we do X (and Y), and it has a result of Z, and that is completely expected based on Y, and X is irrelevant as expected."
If we weren't, we wouldn't have developed winglets and other such adaptations...

Is the development of new programming languages evidence that we don't "understand" computers? In some very abstract sense, yes, but in a more practical sense - no.

A less conservative projection has an advanced drive developing ten times as much thrust for the same power -- this cuts the transit time to Mars to 28 days, and can generally fly around the solar system at will, a true Nasa dream machine.

If we had this plus a reduction of cost-to-orbit by a couple orders of magnitude, say getting prices down to $10 per kilo? Space travel would actually become a thing -- something available to most people. And we could lower cost-to-orbit in a lot of proven ways, like using mass drivers for non-human orbital insertions.

This is firmly in the "too good to be true" category right now, but hell, I'm a believer. Even if we're wrong, even if there's some experimentation error, science still wins. People are being energized, lots of imaginative scenarios about space travel are playing out across the net, and so on.

This is a very good thing.

The bad thing is that embargoes (and counter embargoes) hit ordinary people hard, not politicians.
Prices have increased by ~15% since January (and will increase more because of new embargoes). Many idiotic laws has been adopted. Other countries hate us. And so on.

Russia is now isolated from civilized world. And our government escalates this isolation.

I'm going to migrate to Australia/New Zealand/USA etc. But now it feels much more difficult to move to another country.
Can you elaborate? For example, what is the end-goal of technological innovation? What's the end-goal of any job?

To me, the point of innovation is to make people's lives better. Growing pains, a temporary loss of one type of job, those are inevitable when talking about innovation. But people adapt, they get new jobs, sometimes enabled by the very innovations that displaced them in the first place. That's fine, that's the pattern in the world so far.

A blanket statement like this seems to say that progress for its own sake should be prioritized over the people said progress is supposed to help.
Introduction to Metaheuristics
I didn't think I could love Cloudflare any more than I already did.
Short version:

Unless they believe the machine breaks some of the fundamental physics laws, the device must emit something. With this definition using a red LED Laser powered by a 1.5V battery in the back of the spacecraft is a "no reaction mass" thruster. The problem is that the momentum / energy ratio has theoretical limitations, and they are getting too much momentum.

Long version (based on a previous comment https://news.ycombinator.com/item?id=7162069):

I’ll try to explain what I had understood trying to find an explanations that don’t break the physics laws.

To move the spaceship you need momentum. You must use some particles to carry the opposite momentum away. It’s not clear, but the main candidates are photons (aka light). (The other possibility is gravitons, but that would be even more amazing)

The photons have no rest mass, but they have energy. So to produce them, you must "spend" some energy. The energy source can be carried in the ship (a nuclear reactor) or absorbed in place (solar panel).

If you are using a nuclear reactor, a small par of the mass of the atoms is transformed into energy and you put that energy in the photons. So the net effect is that some of the mass of the spaceship goes away, and it's no long a "no reaction mass" ship. (The same idea is valid to electric batteries, but the mass difference comes from the chemical bounds and not from the nucleus.)

If you use a solar panel, then when you absorb the photons the spaceship gains a little of mass. Unless you have a mechanism to dissipate the mass the spaceship would get heavier. Luckily, the photons that you are using for propulsion carry a little of mass (and the heat you are dissipating also helps). So this is essentially a solar sail, you get some photons, and send them in a different direction, and the change in the direction of the photons give some momentum to your ship. Perhaps a complex setup (solar panel + led) can be more directional that a simple setup (mirror). Perhaps you can gain a x3 or x6 efficiency. (But someone has to do the calculations, because this might break the second law, unless you get a laser light and also dissipate some heat without a specific direction, and the net result as good as a mirror.)

In the previous comment, throwaway_yy2Di noted that with photons "the ratio a photon's momentum to energy is fixed at 1/c, which is 3.3E-6 N/kW". The problem of photons is that to get some moment you need a proportional amount of energy to create them. Another possibility is to create particle-antiparticle pairs and accelerate them, but this is even more inefficient that using photon and you get less than 3.3E-6 N/kW.

The alternative solution is to accelerate other particles (for example the hydrogen atoms in the rocket fuel), you don't need energy to create them, because they are already there. So you can get more than 1/c=3.3E-6 N/kW, but it's not a "no reaction mass" ship.

They claim 40 microNewton/28W = 1.4E-3 N/kW ~= 400000/c. This is in the like 400000 times the theoretical limit, so they have a measurement problem (or they'll get a Nobel price).
Your judgementalness is showing.

There are equally likely explanations for people sitting around drinking. Maybe they don't work first shift. Maybe they're on vacation. Maybe they're disabled for some reason.

The fact that you leap to "oh the government pays them to be unemployed" is on you, not the government or them.

(also note that it's increasingly difficult to get SNAP benefits in states due to budget cut backs)
> The idea of the government issuing a basic income is that people can choose in their own way how to get food, clothing and shelter, instead of having to settle with whatever the government provides.

More fundamentally, in my view, is that basic income represents the citizens pro rata share of a portion of taxation that represents rents on the commons; the purpose government serves is to collect and distribute for efficiency as N:1 + 1:M interchanges involve transaction costs for N+M transactions rather than the N*M that are required for N:M direct transactions, but government has no reason to choose how the rents are spent (and there are, as you note, all kinds of pragmatic downsides when the government does that.)
If Putin's willing to go to that level of provocation, why bother with a sub? Sending him on a surface ship is easier, cheaper, and less of a security risk. It's not like the US is going to try to board a Russian military vessel.
That would put the US in a fantastically difficult position - they can't be anti-Snowdon but pro someone doing it to another government.
It's probably powered by N-rays.
NAT requires each and every packet to be rewritten with different source (or destination, or both, depending on the flavor) IP addressing information, so it isn't just a simple copy.

Drivers and sanity checking what's going in/out of the VM probably account for the rest. Hardware may be fast but adding layers of complexity will have a performance impact.
Have a look at the Cubieboard, and the PCDuino - But be aware many on ebay are based on the A10 which at 1GHz are reasonably quick, the newer ones (hence more expensive) are based on the A20 and more development is done on those these days. The two boards above have lots of GPIO and some revisions have a SATA socket too so you can hook up a laptop drive. They all have real (not usb) ethernet ports, and can drive their USB ports with a sensible amount of juice, unlike the PI.

The MK8xx devices all seem to be A10s (but that might have changed now)
It's going to boil down to this: small businesses will fertilize the industry and then when laws get standardized across the country the big pocketed companies will buy their way in. I would bet that tobacco and pharma companies are stockpiling cash offshore to buy into this market in 3-4 years

Where is the write-protect screw in that picture?
Writing code from the outside in. It's more iterative, experimental than TDD.

So we're just done with providing natural stress on the population, where each person strives to learn and do things that other people appreciate? Instead, we provide the option for "checking out" and getting paid no matter what?

Even if I bought into the narrative of the end of useful labor, which I don't, and even if I bought into the narrative of people who can't be trained, which I don't, the economics of this don't make any sense to me.

I wouldn't oppose it, though. Instead let's get a few dozen small experiments going, see how they work out. Even bad ideas are good if you can learn from them. The real enemy to progress is the idea that we are forced to either reject new ideas like this in their entirety or embrace them at some huge scale.

I also generally subscribe to the idea that, if you can't adequately explain something to someone unfamiliar with the idea, then you don't properly understand it yourself. But my inability to explain something to someone says nothing about whether the phenomenon "is understood" in the more general sense.

Behind the scenes with Twitter and why they use Apache Mesos
Most countries already have that central authority, so that's not a particularly big hurdle. Note that for most of the history of copyright in the US, it wasn't automatic, and you had to register your work. Automatic copyright for simply creating something didn't happen in the US until 1989. There's still a central authority, as registration is still required for certain additional whatnot.

Of course, "that's how it was" doesn't necessarily make it a good idea. But it's not completely disastrous.

I think most of your objections would be solved by a sort of hybrid system that I hinted at. Don't start the exponential renewal until the 20 year mark. If you haven't learned about the need for renewal by then, you clearly don't need it. Start it at a dollar, so it's a tiny barrier for anyone making any money at year 20.

By year 30 it'll be a thousand dollars, and by year 40 it'll be a million. This will start to scare off small time folks who aren't making a ton of money. Highly profitable properties will be able to afford the fees for a while longer, although year 50 will hit a billion dollars a year, and soon after it'll exceed the GDP of most countries.

So in essence, it breaks down to a 20-year period for even the worst crap, a ~30 year period for obscure but selling works, a 40 year period for properties that continue to be fairly profitable, and maybe a 50 year period for Mickey Mouse class stuff.

I think 20-30 years should be plenty to figure out how profitable something is going to be, so it shouldn't much depend on how much money people had before, but how much they can make from the work. If we consider that a proxy for how valuable the work is to society (a bad proxy to be sure, but perhaps better than nothing) then why not allow profitable works to last longer? Make some money for Uncle Sam too.

I've read the abstract, but apparently Wired has access to more information. Any idea where the primary source for that information is?

I'm interested to see what magnetic shielding was used and how well they characterized the magnetic field in the experimental volume. There was a mention of shielding against electromagnetic effects, but that could just mean a Faraday cage or Helmholtz coils, neither of which will reduce the B-field to zero.

Because the device is based upon microwaves in a conducting cavity, I would think that the first place to look for a theory of operation would be E&M, not quantum. The level of force involved is the kind that you can see when interacting with the Earth's magnetic field. Normally we ignore the force produced by the interaction of currents with the Earth's field, because they are so small. Was a mu-metal shield used, and if so, what was the remnant field? Was a stronger field induced to see if that increased the force? I hope that the experimenters try this if they have not already.

I agree wholeheartedly with this. I go to Stanford and took the compilers course this past spring. Honestly, I almost dropped the class after the first 2 assignments because having to learn Bison and Flex to implement a lexer and parser taught me very little about what was actually happening under the hood and I spent most of my time figuring out the syntax. Static analysis and code gen were really cool though and I feel like those assignments taught me a lot more about what modern compilers are actually doing and how they can help optimize my code.
You can use a self signed cert between CloudFlare and your server by the looks of it. The optimistic point though I agree on. Hopefully there's some way of telling if your traffic from CF to origin is secure.

> Why a basic income? I propose basic welfare, food + clothing + shelter, even entertainment. Mass produced in order to minimise costs.

Because basic income respects human freedom, and as automation advances and the rewards of the economy in pure-market terms increasingly shift even further from labor to capital, a basic income that is adjusted in amount as the economy shifts provides a comparatively light touch redistribution represent rents on the commons that maintains opportunity (as the recipients can choose how to allocate the basic income between present consumption needs and investment in personal development and/or capital) whereas "basic welfare" creates a permanently dependent, effectively unfree, class with no mobility, opportunity, or effective choices.

"We still can't make up our minds as to how wings work, so this isn't overly novel. Sure, we can explain the outcome, but whether it's Navier-Stokes or Bernoulli or something else, we can't make up our minds."

Time to trot out my favorite quote about how airplanes fly, from Stick and Rudder by Wolfgang Langewiesche, page 9, published 1944:

»The main fact of all heavier-than-air flight is this: the wing keeps the airplane up by pushing the air down.

It shoves the air down with its bottom surface, and it pulls the air down with its top surface; the latter action is the more important. But the really important thing to understand is that the wing, in whatever fashion, makes the air go down. In exerting a downward force upon the air, the wing receives an upward counterforce--by the same principle, known as Newton's law of action and reaction, which makes a gun recoil as it shoves the bullet out forward; and which makes the nozzle of a fire hose press backward heavily against the fireman as it shoots out a stream of water forward. Air is heavy; sea-level air weights about 2 pounds per cubic yard; thus, as your wings give a downward push to a cubic yard after cubic yard of that heavy stuff, they get upward reactions that are equally hefty.

That's what keeps an airplane up. Newton's law says that, if the wing pushes the air down, the air must push the wing up. It also puts the same thing the other way 'round: if the wing is to hold the airplane up in the fluid, ever-yielding air, it can do so only by pushing the air down. All the fancy physics of Bernoulli's Theorem, all the highbrow math of the circulation theory, all the diagrams showing the airflow on a wing--all that is only an elaboration and more detailed description of just how Newton's law fulfills itself--for instance, the rather interesting but (for the pilot) really quite useless observation that the wing does most of its downwashing work by suction, with its top surface. ...

Thus, if you will forget some of this excessive erudition, a wing becomes much easier to understand; it is in the last analysis nothing but an air deflector. It is an inclined plane, cleverly curved, to be sure, and elaborately streamlined, but still essentially an inclined plane. That's, after all, why that whole fascinating contraption of ours is called an air-plane.«
I think it's pointless to have to memorize it. You need to know the events and the general timelines, but does it matter if it was 1492 vs 1500? It's okay for your brain to generalize and compress a lot of that knowledge, the context will still be there for general discussion. If suddenly the exact date does become important, it'll take our kids 90s to look it up.

As technogy gets more integrated into our lives (think Siri), that could drop as low as 30 or even 15 seconds.

What's important is that you are able to have an informed and intelligent discussion about the topics you learn in school. The exact year of the Emancipation Proclaimation is less important as long as you understand the events around it. Same thing with the melting point of Gallium. There's no need to memorize that, as long as you understand the general concept that Gallium melts at a very low temperature, and what this means in terms of its uses.

That line caught me too.

It makes YOU (the consumer) less vulnerable to "hacking" (MiTM), it actually doesn't make the website less vulnerable and as you quite correctly pointed out somewhat more (just due to increased attack surface).

That's a large part of the reason HTTPS/SSL isn't more common: It doesn't benefit the website as much as it benefits their customers and there are both real and perceived costs in deploying HTTPS.

So you have to put pressure on them (websites) to adopt secure defaults. Google are now helping hugely.
Uh... how exactly do they see "basic income" and "government-run" as opposites?
Can you imagine government-issue food, clothing, and shelter? That's destined to be some horribly depressing Soviet-type shit right there.

With a basic income, even the people who are not working can participate in the market and drive the competition and innovation of people who are producing goods and services.
Which you don't really need to. Sure it disables all the security, but if you only care about the speed boost/cover your ass part it is a non-issue.
