They explain 1:N relations in the article, so I won't repeat that here. A N:M relation will be presented the same way as in all other relational databases, it requires a separate table with rows containing both keys. And if I'm ho

Your explanation is definitely better than mine. I just wanted to rebuke the notion that it was Signal who inspired Whatsapp to use e2e.

Not sure if you've got your sequence of events straight. End-to-end encryption was added to Whatsapp after it was bought by Facebook, before the co-founder of Whatsapp left to found Signal. It's not as simple as Signal inspiring F

There are ways to 'approximate' a uniform distribution by just choosing greater and greater ranges and then normalising the result. One problem with this is that there's no one way to do it. You could argue equally well that

Why is it important that a website should have access to my serial ports?

Except for the people using firefox (stable), or any mobile device. With freeglut it's fairly doable to make a version that has wider support than this webpage. Though I definitely prefer this post's syntax to OpenGL. Not sure if

Ah, yeah makes sense that animals couldn't see it if it's not really part of sunlight. I was thinking it was not physically impossible, but it would be remarkably pointless if the light is simply not there.

More to the point >400nm is visible light, this puts 148nm well within the ultraviolet range. Though it's not too far removed from the visible spectrum, wouldn't surprise me if some animals could see it.

I honestly don't know, I encountered the concept during my study, but it took lots of practice to get comfortable with it. Most articles I encounter are too practical to really foster understanding, or too technical to work as an intro

> Using the next two charts to illustrate this point Good on you for using graphs to make your point, but if you don't label your axes or caption your figures I haven't the faintest clue what I'm looking at.

Shame this doesn't include my favorite description, a 4d vector in projective affine coordinates. Instead of a normal and point or constant you get (x,y,z,1) . P = 0. The translation between the two is trivial. If you want a plane span

The NUTS sampler limits how much tuning you need. As far as I know it's currently one of the best algorithms for sampling the kind of posterior probability distributions you get with Bayesian methods.

HMC allows you to jump quite a large distance by obeying the 'equations of motion' of the 'Hamiltonian'. This helps give more diverse samples, making them less correlated thereby increasing number the effective number of

Title is a bit confusing given that La Niña tends to lead to lower temperatures. The article does clarify things a bit > Niña usually leads to declining temperatures, but the lag in when the effects take place means that 2024 will likely

I've found that reading more into these 'accidental' similarities is a lot more useful than not reading into it at all. For what it's worth there is a parameter in front that functions as a kind of temperature, except th

It's perhaps useful to note that their notation is not accidental. When they state: P = 1/Z exp -li Hi They're directly referring to the Gibbs distribution that pops up in thermodynamics. The Hi are the different ter

Technically they're saying they can read it but wouldn't be able to come up with it on their own. Which is impressive, generally reading code is considered harder than reading it so in that sense it is inhuman.

Interestingly most bugs I encounter are bugs in the specification, so in some ways formal specification just moves the problem.

I do the same with all media I access legally, some of which I definitely do not have a license for. At least I've never seen anyone provide me with a license for anything I am reading on this webpage. It never really made sense to me

I can't tell what the underlying implementation is, but either way you can't modify them without creating a new tuple so they behave as if they use value-semantics not reference-semantics. (this is what makes tuples safe as defaul

I know people underestimate the impact. Before the 1800s or so Europe didn't have negative numbers, except for the odd mathematician who claimed you could calculate with them even if they were obviously meaningless. It was only after b

It's a basic result about utility functions really, except it now works the other way around. When any small amount of money just leaves you in more or less the same situation then your utility function stays constant and then increase

I'm not even sure if it makes sense to view it as a Legendre transform. Or well, it is one, I'm just not sure if it's a good definition . You get the free energy for 'free' if you use a Lagrange multiplier to maxim

I know programmers like to blame mathematicians for writing functions with lots of one letter variable names, but it's the physicists who insist on doing so without defining any of them. You want to know what V is? It's clearly th

This sounds like just a weather simulation, is the term "digital twin" just a fancy new term for a simulation?

I find that uBlock origin also improves things a bit, though it won't do much more than hide the notices. The "I don't care about cookies" extensions tend to consent automatically, so if you use those you should also m
