Karl Stefanovic's sexism experiment: Today presenter wears same suit for a year
Absolutely right. I've gone through the dark times of wondering how to get the linker to stop exploding on me. And when speaking about developing a game engine, it's not just the work required to create feature X, it's the entire ecosystem. Making a sound play or wiring up PhysX is not difficult. Making fifty modules work correctly with each other is the foundation and is not easy or quick. Then there are editor tools, with modern engines providing a full editor suite that would take a team years to make. In the case of Unity, you get correct play-in-editor as well as truly live editing, which allow for incredibly rapid iteration (part of the true secret of efficient game development is being able to go from your shower "ah ha!" moment to a working prototype as quickly as possible). Then there's their asset store with a proliferation of not only art and sound but valuable scripts and entire systems or engines. And while I'm making my game, the middleware company is making my tech better by fixing bugs and adding features, with nearly-push-button support for over a dozen modern hardware platforms to boot.

I can see lots of reasons to develop a game engine from scratch, but they become less compelling every year.
Should the United States Declare Books an ‘Essential Good’?
It already is, though not for hotel room doors/etc. I used to have access to a colo where racks rented individually (i.e. not in a cage) had a combination lock that was electronic. To use it, you first "charged" it by turning the knob back and forth a few times, then entering your code. The correct code mechanically connects the knob to the locking mechanism, so turning the knob unlocked the door.

In the case you mentioned, I do wonder if you could get a bit more energy from the door itself rather than just the handle. For example, if the spring-loaded self-closing mechanisms weren't just mechanical, but used that energy to generate electricity, you might get a bit more out of it.
Thanks for this!

Nowhere, so far that I have read, have the scientists used the word "stupidity" as has the originally linked Newsweek article.

It was completely unnecessary for Newsweek to dumb down the research this way. Firstly cognitive impairment is not the same as general understanding of "stupidity" - a pejorative. Many things account for what we would usually term stupid behaviour. Personality, stress, hormonal balance are good examples. Then again, cognitive impairment includes a myriad of brain function impairments including memory loss ... forgetting something is hardly considered "stupid".

The research is important, but the careless use of words by Newsweek doesn't do justice.
Yea, MS does offer custom support for older service packs too but it has been years since XP SP2 left support.

> All components of a quantum system are always entangled.

No, that's not true. If it were then there could never be direct observation of quantum interference because entangled particles do not self-interfere.

It is true that entanglement is very common, and an unentangled state is the unusual case. But it's not true that unentangled states (or, to be precise, unentangled degrees of freedom) don't exist.
Quantum mysteries disentangled [pdf]
Roads connect me to the entire world, just like the Internet. When I arrive at a destination, it is a separate dwelling than all the other dwellings.

Make sense?
The point is that entanglement always refers to an a priori choice of subsystems (say, Alice and Bob). This is the part that makes the phenomenon non-trivial. If there are other systems around (say, Eve the environment) then the joint state of Alice and Bob will be usually be mixed as a consequence of for the "trivial" reason that we discussed in the previous posts (to adapt a famous saying, almost all components of a quantum system are always mixed ;-). There is nothing "unreal" about mixed states, and not all mixed states lack entanglement. However, for mixed states, being entangled is no longer the generic behavior. The unavoidable interactions with the environment are the reason why it is hard to maintain entanglement between subsystems.

To say that we should do better and bring the environment back into the picture is missing the point if we are interested in the correlations between Alice and Bob. These do exclusively depend on their joint state (mixed or not).
Might be a reason they're deploying to the Persian gulf..?
man, 'vei just read what the Petrie multiplier is. It clearly explains why, given equal sexism by men and women, women's experience is worst. Thus to equalize experience, according to the Petrie multiplier, men should decrease their sexism way below women's. Forcing men to decrease their sexism way below women's is an attack on men by definition, and the Petrie multiplier provides mathematical foundation for it.

I really doubt people would be freaking out on twitter if some animated firemen looking guys were printed on his shirt, especially if was an established art-form like anime. I guess what offends one offends all and should be banned because it promotes oppressions, a lot to read into from the anime printed on a shirt.

I'm guessing a cast. The infinitely long type is not at all a problem in languages with weak type systems like C.
Actually, Illumina's $1000-genome machine is 10 machines, and the way you get the $1000 genome cost is by running around 18000 samples thru in a year.... And when the bioinformatics folks talk about a '$1000 genome', they actually mean the cost of reagents.

Naked cognitive dissonance
> ... I've dabbled in it since, rarely, but I think the old habit of "install everything via ports" is so ingrained in some of us whose FreeBSD use dates back that it's a bit difficult to overcome. :) ...

Ports is still fundamental, but often enough a problem. Not only do some ports take a long time to compile (like Firefox) but a little too often won't compile--maddening when that happens 2 hours after entering "make".

OTOH "pkg" is stable and convenient to use, lately showing no glitches, certainly fewer complications vs. portage, rpm, dpkg, et. al. (Don't know enough about Arch to comment on it.) On the whole pkg is pretty painless.

> (Is Java still a colossal pain?)

Yes and no. I installed openjdk 8.x the other day using 'pkg search', then 'pkg install'. Quite simple. However, if for some reason the Oracle version is necessary, then you'd have the hassle of getting it from their site.

> ... I (mostly) stopped using FreeBSD ~5.x ...

Maybe I should feel a little embarrassed that I still have one DB server which has been running FBSD 6.0 since 2005 (I think). And it's been running continuously, only stopping here and there because of power outages. Haven't changed any of the software, the only maintenance has been backing up the DB, rotating logs, and so on.

I keep meaning to update that system but I don't seem to get around to doing it. After 80,000 hrs on the job I guess we might call it "stable".
Meh, it was still a weird interview, especially combined with his shirt. I watched it live with my fiance and we were both confused and actually said out loud, "We'll be hearing about him later on."

I don't think he's sexist, I'm sure he's a well-respected and well-liked scientist, and I don't think it's fair to judge someone's worth based on a short interview when they're not used to being in the spotlight.

At the same time, I would expect more professionalism from the whole staff at ESA. Are there any offices where wearing this [http://i.imgur.com/oJ9bVDt.jpg] shirt would be okay? People are making a big deal about the fact that a woman made the shirt for him, but they seem to be omitting that he provided the fabric and asked her to make it..

A large part of the rationale for missions like Rosetta is the inspiration it provides to the next generation of scientists. Hearing crude jokes about how 'easy' the mission was from a guy wearing a nudie shirt doesn't exactly invoke inspiration. It's a shame all of the other incredibly smart, professional, and inspirational people involved with the project are overshadowed by this.

As someone who used to work at JPL I find this story hard to swallow. It's not that it's unlikely that an Israeli spy could get a job at JPL. That I don't doubt. (In fact, I'd be surprised if it hasn't happened.) What I find doubtful is that anyone could find out about it. Information security at JPL is not very tight. It's not the NSA. You'd have to be the world's most incompetent spy to let yourself be discovered by a colleague at JPL.

It's worth pointing out that this is one person's allegation and that it is being made in the context of a retaliation complaint against an employer. Some of what is in the complaint doesn't make a lot of sense, for instance, if someone was actively engaged in espionage, why would they post restricted technical information to a public website 65 times?
Whenever I run out of charged rechargeable batteries I toss in Duracell batteries because they stand up to the abuse of camera flashes and other portable high drain lighting equipment for photography shoots. Even if the pack of Duracell batteries costs one dollar more the extra time and usage I get out of them makes them more cost effective.
To condense what you're saying to its core: you can avoid the need to make callers async if you simply make everything async.

In essence, that's the choice Go made. It's certainly simpler for the programmer. It probably makes optimization trickier, and it probably makes efficient parallelism harder (since real threads are completely abstracted away, the VM needs to understand when to start real threads, and when to use promises).

For a language like javascript, it sounds like these tradeoffs are certainly worth it.

I make a gizmo that runs on batteries, and a few years ago, tested several brands of 9-V alkaline batteries under a load similar to my product (a few milliamps). I also wanted some batteries known to be discharged by a certain amount, to test the performance of my product under those conditions.

I tested name brands and the drug store house brand. Within experimental errors, they all had the same lifetime.

> their "canary"

while that's sort of true, the big distinction is that the features in their "canary" aren't going to hit "stable" for another year or so, which is a lot of iterations of Firefox and Chrome in the meantime.

However, it is fantastic to see where they're headed with IE12.
David Mermin wrote a classic paper that illustrates the strange statistical properties of entanglement in a way that doesn't require any physics knowledge.

http://web.pdx.edu/~pmoeck/lectures/Mermin%20shorter.pdf

"A simple device is described, based on a version of Bell's inequality, whose operation directly demonstrates some of the most peculiar behavior to be found in the atomic world. [...] The extraordinary implications of its behavior should be evident to anyone."

A quick search also turned up this animation that demonstrates Mermin's device:

I think either you're confused on an issue or I'm confused on what you're trying to say. Quantum interference is observable with even a single particle.

> because entangled particles do not self-interfere

Entangled particles certainly can, and do interfere (as mentioned, electrons in an atom are entangled and definitely interfere; there's a whole field devoted to calculating this effect), so I'm not sure exactly what you mean here. Can you give me, in ket notation, an example of an unentangled state? (And if you're referring to a direct tensor product of two single particle states, I'm still considering that an entangled state since it can unitarily evolve out of that configuration into one that can't be written as a tensor product).
Good stuff. Basically it seems to do the bind+listen for you if you are the trigger subscriber. If you are the trigger generator, then it does socket.write for you. But the big deal is that you dont pay for 'listen', just pay for the function execution.
The one thing that will surely happen with this is that the code written will be 'locked in' to run only on aws territory.

Hmmm...

DFT is a method. It has been used by physicists for the last 40 years to model the solid state. What you put forward in your third paragraph is not quite right - things are more subtle.

What you seem to be suggesting is that we should be free of the Kohn-Sham framework[1,2] or find the exact XC functional. Not surprisingly, the results of calculations depend on how the functionals were constructed. But that doesn't mean "DFT" is bad. DFT's just the method. There is no approximation in DFT. It is in itself exact for the description of the ground state.

I saw one in my city in Scotland a while ago, having never seen one IRL. It looks extremely distinctive; it's not exactly sleek and hidden. It's the sort of thing that pattern-matches quite quickly.

(My immediate impression of the wearer, for the record, was that he was likely a director of an oil-related company looking to show off his wealth.)
These topologies (both logical and physical arrangement) were quite popular for non-ethernet networks in 90's (in both super computers and phone switches). AS it is reasonable way to get large fabric that has reasonable performance yet is composed from relatively small switching elements with reasonable cable routing between them.
unnamed classes with an () operator

They do have a name, but unfortunately it's just a compiler-generated one that's not known beforehand. And you would think that because the body of the lambda is really inside an operator(), 'this' could naturally be used to refer to the lambda itself, but alas, it doesn't work:

http://stackoverflow.com/questions/14531993/can-lambda-funct...

This is one thing about lambdas that I think the standards folks messed up. Having a lambda call itself might not be such a compelling use case, but it comes from the more general fact that a lambda cannot refer to itself, even though there isn't any reason preventing it from doing so; e.g. being able to pass itself ('this') as a parameter to some other function can be very useful.

Just start reading the source of projects you use and see how they work. When you see something wrong or need a new feature you create a fork on GitHub and work on that. You then create a pull request when it is ready! If you're unable to 'deliver', just don't create the pull request. Start small with tests or docs, then bugs and small improvements, then new features, then big refactors ;-)

Great book! I have spent hours reading it multiple times soaking all information I could.

Again, it's not as straightforward as that. It was started under Reagan and never adequately funded which is why it was behind budget and schedule in 1993. Cato and other conservative think tanks came out strongly against it in the early 1990's as well[1] which is why Bush dramatically cut funding in his budget in 1992.[2] When it came down to the final vote in the Senate to kill the program, 53% of Democrats voted to keep it (29/45) and 70% of Republicans vote to kill it (31/44).[3] The Republicans then went on to a massive sweep in 1994 based largely on promises to dramatically decrease government spending, where they highlighted projects like the SSC as wasteful.

There is plenty of blame to go around.

This reasoning does not make sense. The notion of entanglement is not invariant under "global" operations, nor should it be.
I've heard that Sendai is rapidly becoming the Silicon Valley/SF of Japan, so it would be interesting to see comparisons between those two.
I agree, there were more interesting/amusing cover illustrations than the abstract, generic ones on the bulk of compiler and computing books today. That's how the Dragon Book got its name too.
