Quote: the “training sessions,” where the dogs did all their learning, took place within a computer. “We introduce a method for training a neural network policy in simulation,” the authors write, “and transferring it to a state-of-the-art legged system, thereby leveraging fast, automated, and cost-effective data generation schemes.” The artificial intelligence — here applied to a specific dog-sized machine named the ANYmal, but the method should work on any machine — learns all its tricks in the digital world, where there are no complicated and expensive parts to engineer and replace, then shows off its abilities in the real world.
Using this technique, the researchers improve on all previous attempts to manipulate such robots, achieving a new level of control and efficiency. In particular, ANYmal can now run up to 25 percent faster than ever, and it recovers from all fall it experienced in real-world testing. (Hence the abuse, above.)

Well enough to know that it's real name is "gong fu"?
Those bluddy English forringers in Hong Kong gave it the wrong name*.

Knowing your irony/sarcasm skills and not being english speaker... I need clarification.
Are you telling you didn't know about "Kung-Fu"?
Ae you telling I don't know that it actually is "Gong Fu" (AFAIK that's related to the tea ceremony)?
Or are you just kidding me in a way I don't realize?

I was jovially inquiring whether you knew that the real name of the martial arts system is "gong fu", which it is.
If you were to go to the Shaolin temple and call it "kung fu", you'd get kicked all round the square -- mind you, that seems to be what most people go there for, so maybe it's not so bad an idea.

No I didn't. I had always related "gong fu" with the tea ceremony.
In Wikipedia:
Quote: In general, kung fu/kungfu or gung fu/gongfu (/ˌkʌŋˈfuː/ or /ˌkʊŋˈfuː/; 功夫, Pinyin: gōngfu) refers to the Chinese martial arts, also called wushu and quanfa.
I always say... a day when you learn something new, it is not a lost day. So, thanks for the new thing

Note that, even though the remarkable* wikipedia gives preference to every other pronunciation, the only one that's actually in Chinese is "功夫, Pinyin: gōngfu", which means that it is the real name of this Chinese thing.
It's us bluddy forringers that get it wrong.

Quantum machines will deliver the next great leap forward in computing, but researchers building them can’t easily get some of the exotic components they need. They're not USB-C?

Some magazine wrote: Unlike classical bits, which can represent either a 1 or a 0, qubits are particles such as atoms or electrons that can occupy a quantum state of both 1 and 0 at the same time, taking on a definite value only when they are measured.
That implies it doesn't exist until it is observed, which is nonsense. Part of the problem is that you can only read it with one observer - you can't measure it with two observers at the same time.

AI and ML systems are turning the professional gambling world on its head. Maybe they're past the Turing test, but are just bluffing (for now)

Bluffing = Pretending to have what you don't have, or pretending to be able to do what you can't do.
So yeah, that's pretty much the state of AI, these days.

It could be worse than that, namely an AI actaully don't know what it know or don't know, it just response, with confidence. Call this bluffing is not accurate.
IMHO, knowing there is unknowns and what are known is a necessary condition for (A or H) intelligence

The pImpl idiom is a useful idiom in C++ to reduce compile-time dependencies. Here is a quick overview of what to keep in mind when we implement and use it. This just popped

This is true (and a PiTA).With pImpl, that is not the case wrote: With pImpl, that is not the case
This appears to be true, and I'm willing to give it a try.
My only question: What could possibly go wrong?
I don't think I'll be trying it out in production code this week.

Here's a semi-pImpl implementation that has some of the benefits and not all of pain. I popped it several years ago, and haven't heard about it anywhere else: Two-thirds of a pimpl and a grin

A new study uses an analytical technique called 'network science' to determine factors contributing to statistics anxiety among psychology majors. Fear is the grade killer

Oh, fer f***'s sake!
tl;dr: people get nervous if they have to take exams in complicated thingies that they haven't been taught well.
We had a statistics course as a module in our programming degree. I was OK with Maths, so paid no attention at all during the classes (because I was too busy writing code for the few modules that actually required any programming), and only played with it for a couple of days before the exam (what I do can, by no means of the imagination, be described as "revising" or "swotting").
I passed the statistics exam with 100% (which I wasn't incredibly happy with -- my best pass of an exam was 102%, in Physics), because I had done enough to understand the subject matter, so I was not afraid of it.
So I would posit, based on personal experience (and common f***ing sense), that if you are a teacher and your students are afraid of taking exams in the subject you teach, then you are a f***ing useless teacher, and that inventing non-sciences such as "network science" to try to cover up your incompetence only demonstrates what kind of useless @rsehole you are.
- Them as can, do.
- Them as can't, teach.
- Them as can't even teach must be completely f***ing useless, no matter how much they try to cover it up by sounding clever.
