Black silicon photodetector breaks the 100% efficiency limit
Serious question: if true, how is this not an example of entropy of a system decreasing? I must be missing something, because entropy always increases, but the article doesn't give enough info to tell. Could it be that the energy level of the photon was initially higher than the energy level of the electron?
After some thought, that must be it. So the title is a little misleading??? Even though it says "...The external quantum efficiency of a device is 100% when one incoming photon generates one electron to the external circuit..." Kind of a misleading definition of efficiency?

Efficiency may be defined in many ways, not necessarily related to energy usage.
- Energy efficiency - the ratio of energy going in to "work" coming out
- Particle efficiency - the ratio of photons going in to electrons coming out
- ...
It all depends on what you want to measure.
In a photomultiplier, which is hardly a new device, a single input photon can trigger multiple output electrons, at the cost of supplying additional energy to the system.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Be careful you measure the right things. You will optimize for what you measure, not what you need.
Remember when programmers were measured in Lines of Code, and number of Bugs fixed.

But if the rat is making bar presses and you're busy tallying the number of food pellets delivered by lifting your pencil to make a scratch mark in your notebook, the rat might see you being inattentive and change his behavior accordingly.

Apple and Google are acting like bullies, but Epic has tried to fool the rules.
IMO both sides are right, what actually means too that both sides are wrong.

Calls via the LTE mobile network, also known as 4G, are encrypted and should therefore be tap-proof. Posted entirely to scare the bejeebers out of you (but don't worry too much)
One of the most obscure hacks out there, IMO: "They were able to decrypt the contents of telephone calls if they were in the same radio cell as their target, whose mobile phone they then called immediately following the call they wanted to intercept."

How many hacks do you know that don't rely on incompetence, lack of ability, lack of ethics, greed or a mix of all along the chain of the product?

Unless you define incompetence/lack of ability as anything short of perfection, not many

Haha, I meant it more like if you define it that way, the answer is none, but if you don't, there are some that are reasonable because they deal with some really complex stuff (like many of the linux kernel exploits).

Not sure it really matters. Nothing is unhackable.

That is what doesn't really matters... There is no 100% security, that's something already known... but has to be that easy so often?

Microsoft Premier Developer: similarities and differences on important topics for C# developers learning Go.
I think they had to pay attention while writing this sentence...
It could have said: Quote: similarities and differences on important topics for developers Go learning C#.

Quote: I explain my motivation and experience learning Go coming
I read that as:
Quote: I explain my motivation and experience learning Go comically
I kid you not. I obviously clicked on the link with a pre-bias.
I had to quickly reach for the barf bag -- my mask wasn't big enough. Why in the world would I want to learn Go? It looks like a mashup between C++ and TypeScript and bad JavaScript. 
Look, one of the reasons I love C# is because I find the language syntax itself beautiful and aesthetically pleasing. Yes, programmers can turn any work of art into a bucket of bloody body parts, but that's not the language's fault.
Go, well, it looks like what is in the bucket.

Only because you can doesn't necessarily mean that you should.

I never said we should... but another thing is waste it with non-sense.

Like said make-up?
Or action figures?
Or video games?
Or yet another Hollywood movie / Netflix series?
Or going into outer space?
Or the biggest nonsense of all, weaponry?
Probably, when you're starving, everything that isn't water or food or housing is pretty much nonsense

Some kind person has sent me an email saying that one of them has died and, if I give him my bank details, I can share the late lamented's money.
