> but so far you have to build and flash your own AOSP image

I think you're going to see more people doing this, with the Nexus devices and the Transformer tablet. Maybe I've overestimated the popularity of the ASUS-branded hardware, but I have always had the best of luck with my TF-101 getting current ROMs and updates from the third-party vendors like TeamEOS.

Now that TeamEOS is gone, there's a void, so more people are probably going to learn to build the ROMs. There are even people picking up the torch[1] with the TeamEOS source code, taking their branches and picking up where they left off.

I know as consumers, we all want vendors to support their products... but as members of Open Source community, I see it's irresponsible to depend on them exclusively for forward motion, progress, and updates, and for freedom's sake it shouldn't be an impossible proposition to compile and flash your own ROM. (Just think if you bought an x86 computer with Ubuntu or Fedora and you couldn't re-OS it.)

I guess the bureaucracy and politics of scientific research is not much different than in any other arena of human endeavor, still, it seems particularly sad to imagine a bunch of scientists fiddling around with Photoshop so that their PDFs can "really pop!" (to use a common marketing design phrase).

I don't read a lot of scientific papers, but has there been much meta-research done to try to quantify attractiveness of scientific paper presentation and correlate it with number of citations (or some other qualitative measure)?

I never understood people who said that the internet was a way to reduce the abuse of power by governments or corporations. They are good at wielding power, and many of them don't have any trouble adapting to the internet. They may be a few years late to the party, but the internet gives them the same power as it gives everyone else, and they have a head start on power.

>How do you hide a CO2 footprint, when that same footprint could be smelled by a from musquito 100 meters away?

If the mosquito can find you from 100 meters away, that doesn't mean it can find you once it gets 1 meter from you and its CO₂ receptors are confused.
If PAX or anyone else wants to intentionally price something so that the demand is larger than available supply, then in any case the "effective price" will be raised so that supply matches the demand.

In effect, part of the "effective price" will be the monetary cost, and the other part of the price will be wasted time/emotions/connections/whatever that discrimiminates those who get the ticket from those who don't. This is basic, well researched economics, with plenty of real life examples in various countries, regimes and industries.

The common options include:

a) $x + significant time spent waiting in line - some wait in line and get nothing; some value their time a lot and don't attempt buying.

b) $x goes to the original supplier, $y goes to scalpers/touts/your employee bribes - the stuff gets sold at money market price, but someone else gets the difference;

c) lottery - either intentional lottery, where everybody has a chance of getting a ticket for $x despite that it's market worth is >$x; or an unintentional lottery, where random factors (showing up at the right time, getting a reservation that someone else cancelled) determine if you can or cannot get the ticket. In both cases, the "buyer" might be motivated to resell it if possible, since it's possible that he paid $20, he wouldn't go if it cost $100, but someone else wants to pay $100, so ...

d) (ab)use of advantages - political connections, bots, whatever; you buy at $x and sell at the market price.

In any case, (most) buyers don't get the intended effect of cheaper price; but the seller loses out. Only the middlemen benefit, without adding value. (In one sense, they add back the value that the seller reduced by mispricing)

I've seen what happens in USSR when the majority of economy functions this way - trust me, in most cases raising the price is actually the appropriate response; because otherwise there is so effing large amounts of effort&resources that is wasted - the seller gets $x, but the buyer anyway spends "market price" of $3x to compete with other buyers by giving $x of cash and $2x of wasted, unproductive effort.

WRT the libel claim, I think he did promote the website defacement. Ergo he was a "sponsor" to it.

Her tweet to that effect appears to be true [a partial defence], and as he is happy to have promoted it based on his blog I'd warrant it to be impossible to prove that it defamed him to say that he promoted the crack. Indeed he revelled in the promotion of said defacement.

Case dismissed.

If you are not working at a large game-dev studio, you need both skills. Most of what you need to do is already 'designed' but often you end up taking calls on things that are not clearly laid out for you.

You may also end up working where there is a clear 'game designer' and 'game programmer' separation even if it is a small studio (20-30 people). In both these cases, you need to know your basic 3d maths to be useful in your role.

I concede that it's much easier nowadays since you end up using an engine that abstracts most things for you. Nevertheless, you do end up hitting the limits of the engine and may want to implement that killer feature yourself.

I have encountered all of these situations. I'll say that the minimum you should know if you want to be a game programmer is:

- high school level algebra

- high school level trigonometry

- basic 3d vector mathematics

- an understanding of graphics transformation (and the corresponding matrices)

- basic splines

If you are looking for a very specialised role, then you can probably forget these and focus on say AI or Networking but I see that as too risky in an industry that is already infamous for its treatment of employees.

There is a Wikipedia article about "Quantum superposition". https://en.wikipedia.org/wiki/Quantum_superposition

In quantum states, you cannot know the actual state something is in unless you measure it. Beforehand, you just have different probabilities of where it might be.

A quantum superposition of two states means that there are two states the atoms can be in, with specific probabilities assigned to each state.
Side note: Looks like the clip was lifted from "Tree of Life".
Photons have zero rest mass, but light has an energy of $h\nu$, where $\nu$ is the frequency, so this gets added on to the mass of our thing.

Oversimplified explanation: Photons are massless so they can go as fast as they want without needing kinetic energy, but even massless things can store energy (think of the massless springs you studied in high school physics). Energy is the same thing as mass, but we still refer to photons as massless, in the same way that we think of an (imaginary) massless spring as such; we don't like to think of potential energy as _being the object_, just somehow _there_.

This makes more sense if you study physics, in no small part due to the fact that we make it all rigorous (though not to the satisfaction of the mathematicians, I guess...).

> Since light is effect by gravity, it must have a mass

Sorry, this is completely false. Light is affected by gravity because gravity is really a curvature of spacetime.

* I guess "curvature of spacetime" is perhaps not the most satisfying explanation of why light is redshifted as it moves out of a gravitational potential well (i.e. if you shoot a laser from earth into space). Nonetheless the answer is still "because of relativity".
Raising prices isn't just punishing people - it also increases supply, since if PAX would gain double revenue then it would incentivize both PAX to obtain larger facilities, and others to make more similar conventions more often so that more of people who want to go can actually do so.

I wasn't taking exception with your interpretation but with the argument itself.
My layman's reading of this.

We used a crystal that is normally opaque (not see-through) and fired laser beams at it because, well... it seemed like fun! Apparently the laser beam affected the crystal and made it see-through but only for a narrow range of light frequencies (e.g. think of a filter that only allows one colour of light through). Then we thought Hey, we know how to make this here crystal see-through for a particular wavelength of light (think 'colour' if wavelength doesn't work for you). What if we (1) made it see-through with the laser, (2) shone some of that colour light in and then (3) turned off the laser so that it's no longer see-through. I wonder what happens? <time passes> zOMG! We trapped light!

In other words, I do think it's possible to get the message across without needing to refer to 'quantum' anything. However, this article is from NewScientist and the intended audience is likely to be vaguely familiar with concepts of superposition via stories of Schrödinger's cat [1]

Latest edition out. There's been a lot of news about PHP recently and whilst I appreciate that it's quite a polarised discussion regarding the 'quality' of PHP itself I think its great that people are learning to program with it and that its still relevant all these years after I learned to program myself in it so that I could have conversations with our developers that were more meaningful (being the suit that I was at the time!!).
This is so basic but incredible to think about. How do they know that it is there when it's stopped, provided that it neither has mass nor emits "something"? My brain just stopped.

Correct. Photons are responding to the curvature in space-time, not directly to the gravitational field. Doing a second check, light has inertia-mass, but not rest-mass.
I think a good way to think about sentences like that is that the word quantum is short for "belonging to quantum mechanics", like how "classical gravitation" doesn't mean that there's anything classic about gravitation. The quantum quantifier is there to differentiate the superposition they mention from "classical" wave superposition.

It's very complicated stuff but not "very, very complicated" stuff, you can read Feynman's QED book (http://www.amazon.com/QED-Strange-Theory-Light-Matter/dp/069..., <$9 used with shipping) and obtain a pretty good working knowledge of things.

It probably isn't only a matter of outright corruption, but also of a form of systemic corruption: You don't get selected for congressional committees covering defense and intelligence matters if you are fundamentally skeptical that we still need Cold War-scale mechanisms and new, super-intrusive surveillance at mass scales.

In other words, there is nobody telling them it's wrong and to stop. That's all outside their universe.
Ask HN: What happened to Steve Yegge after 'quitting'
The recent "I'm coding 180 websites' post inspired me to get a group of friends to commit to set aside some time for study hall to work on things once a week--hopefully more often. I used Steve's OsConn talk (google Steve Yegge Quits)to help show the value of study hall hours. Curious to know if anyone has heard an update on his goal of study hall hours everyday for an hour to learn math. Surprised there isn't a follow up talk, post or rant to that talk. Or have you had any success setting aside set time to work on side projects or just to learn something?
Why Those Who Feel They Have Less Give More
What liberal values? The democrats strongly supported the wars in Iraq and Afghanistan, supported the passing and continuation of the Patriot Act, etc. They embraced their status as the "party of the guy that killed Osama" in the 2012 election.

And this isn't a new phenomenon. The Democrats moved hard to the right with Clinton, and have ever since become a solidly center-right party with a social-liberal streak. As a practical matter, that was the only thing that could win elections with a voting population that was solidly center-right.

> Needs to be something like a teaching track

CMU is unusual in being a top-tier school with that arrangement. They actually have three tracks of professors. There's still a "regular" professor with the usual research/teaching mix. Then there is a "teaching" professor, which is also a tenure-track/tenured position, but judged mainly on teaching with research secondary; they are not expected to bring in as many grants or publish as many papers, but teach more courses per semester and are judged more strongly on their teaching quality. And finally there's a "research" professor, which deviates from regular professor in the other direction: they're judged mainly on research, with a lower teaching load, but a higher expectation for grants and publication output.
My family arrived here as refugees after the war, and I grew up acutely aware of the threat of the Soviet Union. Maybe that's why I am also aware that no threat that's within three orders of magnitude of that exists today.

"Thus continuing my inability to understand [...]"

You will enjoy this beautiful lecture given by Dr. Feynman entitled, "Probability and Uncertainty - The Quantum Mechanical View of Nature." [1] In this lecture, he describes the double-slit experiment, which is tied to the topic of quantum superposition.

This particular section blows me away every time:

"Here are the circumstances: source, strong light source; tell me, behind which hole will I see the electron? You say, 'Well, the reason you can't tell through which hole you're going to see the electron is, it's determined by some very complicated things back here: if I knew enough about that electron - it has internal wheels, internal gears, and so forth - and that this is what determines through which hole it goes. It's 50/50 probability because, like a die, it's set sort of at random - and if I were to have studied it carefully enough, your physics is incomplete: if you get a complete enough physics, then you'll be able to predict through which hole it goes.'

That's the 'hidden variable' theory, so called.

Well, that's not possible.

It is not due to a lack of detailed knowledge that we cannot make a prediction, because I said that if I didn't turn on the light, I should get this interference pattern.

If I have a circumstance in which I get that interference pattern, then it is impossible to analyze it in terms of saying, it goes through here or here, because that curve is so simple, mathematically - a different thing than the contribution of this and this as probabilities.

So if it were possible for you to have determined through which hole it was going to go if I had the light on, the fact that I had the light on hasn't got anything to do with it! Whatever gears there are back here that you observe, which permitted you to tell me whether is was going to go through 1 or 2, you could have observed if I had the light off.

And therefore you could have told me with the light off which hole - each time an electron goes - which hole it's going to go through.

But if you can do this, then that curve would have to be represented as the sum of those that go through there and those that go through there - and it ain't.

Therefore, it's impossible to have information ahead of time as to which hole it's going to go through when the light is out - or when the light is on, or out - in a circumstance where the experiment is set up that can produce this interference pattern.

It is not a lack of unknown gears - a lack of internal complications - that makes nature have probability in it; it seems to be in some sense intrinsic.

Someone has said it this way: 'nature herself doesn't know which way the electron is going to go.' A philosopher once said (a pompous one): 'it is necessary for the very existence of science that the same conditions always produce the same result.' Well, they don't: if you set up electrons in any way - I mean, you set up the circumstance here, in the same conditions every time, and you cannot predict behind which hole you'll see the electron.

They don't - and yet the science goes on in spite of him."
