Also, the plumbing of ACME is truly excellent, I hope you can reproduce its power.
I don't mean to suggest it wouldn't be of interest. As you point out it would be of paramount interest to discover the physics behind it. The Pioneer Anomaly, however, was very very small indeed. This effect appears to be many orders of magnitude greater.

Interestingly, I recently spoke to an aerodynamicist and mentioned this, and I was severely lectured. In the follow-up he mellowed a little, but I suspect the "we" in your statement refers to laypersons who don't have advanced training in aeronautics, and yet claim to understand about flow pressure, Bernoulli, etc.

I've been convinced that the people who genuinely work with these things and study them properly, actually do know how wings work. You may not, I may not, the mythical "man on the street" may not, but there are people who really, really do.

Both can be completely correct:

1. I believe Ukrainians would rather be EU citizens and would rather be politically closer to the EU than Russia.

2. I believe the US and other nations have been yanking Putin's chain for various reasons.

There is no contradiction between the two.

It's really sad that he didn't feel he got anything from learning French. I suppose that's the price one pays for having "won" the language lottery (it was a little like that with German 70 or so years ago, I'd imagine). Perhaps French should be dropped from American schools and be replaced by a language that actually is more of a gateway into an alternative culture and history, like Arabic or something...
Photons (i.e EM fields) have no mass, but do carry momentum and can transfer it to charged particles (i.e. the solar sail). So if the drives uses EM field to transfer momentum to the quantum vacuum particles, wouldn't that upset the net-zero energy balance of the quantum vacuum? I though the particles are popping in and out of existence, hence net-zero energy?
I'm sure their salary more than makes up for it ;)
Economics for Entrepreneurs 101: 4 things to know about an economy
No, I've a masters degree in Physics, and did several research projects on turbulent/laminar flow. We have a detailed understanding of a variety of theories which correctly represent the lift effect experienced on a body moving through a flow, yet none of them do it perfectly or completely. We can implement the technology well, but not without the aid of wind-tunnels and brute-force computer simulations in order to validate our designs - had we a perfect mathematical understanding of lift - we would not need to.

Another example from Physics - quantum mechanics. We can describe the properties of a QM system, its outcomes based on inputs, the probabilities of states - yet we have not got the blindingest clue as to how it works. We have theories, but again, none are perfect - for instance see the Pilot Wave formulation of QM, which implies a deterministic universe, and isn't wrong, but isn't generally accepted - even though it describes QM systems well, for what little of it has been formulated in the last century.

This is a post about Snowden, so my comments are also about Snowden. Staying on topic is a good thing, right? I made plenty of comments about the censorship in Russia in other threads.

>Instead, you are complaining about Snowden not instantly becoming Russia freedom activist and general expert on Russia freedom.

Oh, I could compare him to actual Russian freedom activists who didn't run away from their country when things got tough, and went to prison for their beliefs. But that comparison would be unfavorable to Snowden. Did anyone in the world care when Russian whistleblower Alexei Navalny got arrested? Was it on Hacker News front page? Oh, and Snowden was around here when that happened. He most certainly knew it happened (it was big news here in Russia). He didn't even say a word about his fellow whistleblower. This is the shit that drives me up a wall.
In a sense, yes. But space has no medium to convey heat so you can't get rid of it by convection or diffusion. Getting rid of heat in space is hard and a big issue for spacecrafts.
You'd donate to a business for the same reason you'd donate to an individual: to give resources to a cause that you support and to incentivize a direction of work.

The tragedy is here, that it appears that only the russian government is able to give Snowden a permit to stay.

All other european nations have declined to host him, that is until now.

So much about being independant countries...
He has a residence permit that allows him to get past Russian exit controls and travel abroad, so I suppose he can get on a plane if he wishes. Getting off will be a problem, yes. He'd have to arrange something with Ecuador, Venezuela, Cuba, or the like.
When I bought it this Acer C720 was like an experiment, at first I was skeptical.

Now it's my main dev machine: its very little weight enables me to carry it wherever I go, the battery lasts 18h (18 HOURS, CRAZY!) if I read only PDFs, the 2gb of ram and the dual core are just perfect (but not tempting about running virtual machines on it), and with the SSD it performs better than more powerful machines with HDs.

Afaik NaCl from DBJ et al. isn't actively maintained, by them, as an ongoing project. It hasn't been updated since early 2011. libsodium is where it's at now. Going forward, I wouldn't expect TweetNaCl to be either so there's not much of a naming collision.
I seriously suggest if this is a path you are looking for, instead of paying out money, start looking into different occult traditions. I've not had such an experience (honestly haven't yet tried), but people claim it is possible. And you don't need to pay out 10,000 to do it.

Component Based Development and The Future Of The Web Platform
I have fond memories of when we got our Amiga 2000. Must have been around 1986 or so (which would've made me 7 years old). My oldest brother spent half a day installing the OS onto the gigantic 40 MB scsi hard drive. When he was finally done, I spent about half an hour managing to bork the entire system, so he had to do a full reinstall... good times.

Still remember he told me that "it shouldn't have been possible to do that." -- by witch he meant that while it wasn't much of a surprise that'd I'd mucked up the install -- it shouldn't have been possible to do it the way I did. Still don't remember what I did, just that it involved a lot of dragging and clicking. I doubt I'd be able to do the same thing today ;-)
Please, don't be so naive.

Given the scale and duration of Euromaidan the chances of it being a spontaneous phenomenon are zero. It had to be centrally coordinated and directed to last this long. It could've been coordinated by activists, but then somehow all their organizational skills disappeared right after Yanukovich was gone. Just look at the mess that followed. Someone else was directing.

I'd say that it's about on par with the faster-than-light neutrinos caper (tiny effect, violates known physics, probably result of experimental error, ...). Both would be very exciting if actually confirmed, but I personally found/find the chances too slim to (yet) get excited.
> The US is tracking him, so he has practically no chance on a normal passenger flight

Tracking his day-to-day movements, even if he should arrange to get to an airport in secret? Extraordinary. Do you have a link for that?

What I meant was the has a much broader choice of flights and even airports now. The odds seem to more in his favour now, should he wish to move.

Though actually, why would he? I don't see any advantage for Snowden from relocating to the same show, but in Venezuela or Argentina.
Ask HN: Raspberry Pi Clones

To be honest I'm not sure why he would. South American countries tend to have volatile regimes and Russia is probably the best place for him to stay, even occupationally.

Fluid flow is complicated, true - but the basic physical phenomenon of lift is very simple and completely understood: wings redirect air downwards, and the reaction force is what we call lift.
Other parts of the country call these roads "frontage roads" or "service roads" if they are what I'm thinking of (never been to Texas). They do exist outside of Texas; I've seen them in Myrtle Beach, SC, for instance.
I remember test driving an Oldsmobile in the late 80s that had a HUD. The display was outside of the driver's immediate center of vision so it didn't obstruct the roadway, but it was visible without having to look away from the road to see speed, fuel, and some other data. It used a blue vacuum fluorescent display, hot stuff at the time. IIRC though the rest of the car was an absolute piece of trash.

Edit: Ha, my memory isn't terrible: 1988 Oldsmobile Cutlass Supreme Indy Pace Car
"Dawkins’ narrowmindedness, his unshakeable belief that the entire history of
human intellectual achievement was just a prelude to the codification of
scientific inquiry, leads him to dismiss the insights offered not only by
theology, but philosophy, history and art as well."

I suppose vaguely arguable to classify Theology as "human intellectual achievement". Bundling it up with philosophy, history and art and trying to paint Dawkins as being against those other things is just childish.
If you're using the Pi as a media center only, maybe you should consider products like the MK808 which often have Linux ports?

Wow, that's a lot of duplicate articles about this reaching the front page, one of which already contains a complaint about the mods changing the title. They could really do with merging these articles together.

I've previously suggested a feature to show title change histories under the title, before the comments, because certain comments make no sense after the title is changed.

I'd also like to suggest a similar feature for merges whereby when there are separate articles talking about the same thing, the canonical one gets used as the main link and others submissions are retained, again, under the title, before the comments.

You don't have to build something production ready. Part of learning about programming is learning how it helps you with smaller things.

You don't have to write a web server in Perl, you can write a script that saves people from editing some horrible text file in Word to remove extra lines.

Similarly, some apps are complex 3D games, and others are timers that let you know when your egg is cooked, or your break is over.

> There are many explanations for the generation of lift found in encyclopedias, in basic physics textbooks, and on Web sites. Unfortunately, many of the explanations are misleading and incorrect. Theories on the generation of lift have become a source of great controversy and a topic for heated arguments.

There are lots of bits of science where we have "useful lies" used to explain things to people, but when you get more in depth things get trickier.

Clifford Stoll uses the question "Why is the sky blue?" as an example. You keep asking "Why?" as a response and see how far someone goes. Most people will say "light scatters"; some might say "Rayleigh scattering".

Of course, there is a difference between "Science knows but the general population hasn't learnt it" and "science doesn't know" but for a surprising amount of stuff science doesn't know, yet.
Frontage roads take up a lot of space and are not pedestrian-friendly, but they can help drivers. Personally, I'm not a fan of them because I like walkable cities.
It's good to see CloudFlare are going to make this free. In planning the launch of my own new site/blog/thing (hopefully launching soon), the one thing that's really stopping me considering SSL isn't the cost of certificates (which can be had for peanuts anyway if you don't care too much which CA you use) it's the ongoing costs and increased server load.

Right now, launching without CloudFlare would almost certainly result in the unfortunate death of my VPS. SSL would only expediate that. OTOH, the minimum paid CloudFlare package would quadruple my hosting costs - I'm not running enterprise scale infrastructure for my personal site!

If CloudFlare do make it part of their free package, I will definitely use SSL by default.

In there defence this their treatment of revocation requests is made quite plain in their policies, and any heartbleed exposure was not their fault (their signing certs were not affected IIRC).

Now if there had been a problem with their signing certificates then I would have expected them to revoke anything affected for free and offer replacements similarly at no cost.

OK, they could have done that anyway (or perhaps offered a discount on the revoke charge) as an good will gesture, but they didn't, so what.

It might not have been orchestrated but it was heavily funded by the US. I seem to remember watching a video where a Ukrainian girl tries to emotionally explain why people should support Maidan. The video had almost 10 million views. I did some researching and it turns out the video was funded by a US senator. Then there's Pierre Omidyar funding opposition groups through USAID and who knows what kind of other funding Maidan has received.

I don't think it's a conspiracy that US successfully managed to get Ukraine out of Russia's hands. A good thing, some might say.
Well, if brute-force computers simulations correctly represent a wing, then we do know how they work. We may need wind-tunnel tests even if we have a perfectly realistic model, because we may not know if our simulations converge.

It doesn't imply a deterministic universe any more than vanilla many-worlds. Sure, the pilot wave is deterministic. But when you actually measure the position of the particle? You get one of many possible results, with probability determined by the pilot wave. Big whoop.

We understand QM perfectly well in the only meaningful sense - we can predict the results of any experiment. There's plenty of arguing about "what it means" or "what's really happening", but that's not really physics in my book.
You're saying we're trying to turn these "life-long friends into blood enemies", no? The Ukrainians are doing it themselves.

Also, to be fair, I'm not sure it's true Ukraine is "life-long friends". They've been dominated by Russia for centuries. Given the chance to be independent, I wonder if they'd take it.

None of the things mentioned so far that we "don't know how they work" are on a par with this. Flying with wings doesn't violate fundamental, and experimentally very well supported, symmetries like conservation of momentum, nor do high temperature superconductors.

Your final sentence is actually nonsense.
Amazing insight!

Ritual food and drink are certainly common around the world. The thing that pops into my mind is the Japanese tea ceremony.[1]

There's nothing at all saying people can't have a personal ritual - indeed it is very common.

Also I think it might be having a sense of more control over the process is made gives a sense of pleasure as well.

Oh sure, the US tends to support groups that go with its agenda. It helps pro-democracy (and pro-capitalist, pro-free trade etc.) groups. I suppose they could've helped them, I have no idea how that'd work in practice though.

However, I think it's nonsense to suggest it's some massive US/EU plot to get revenge on Russia. It was spontaneous and reacting to something completely unrelated to Snowden or Syria.
