The issue isn't that deterministic models are necessarily untrue. But that it's meaningless to investigate the phenomena as a deterministic one. Even if we knew all of the hidden variables. And had the exact deterministic mathemat

This is a wild over simplification of what 'chaos' theory is actually studying and the statements it makes. Chaos theory in general states that for some deterministic systems, small changes in the initial conditions can lead to a

I'm so confused by this change. fgrep and egrep are already just shell scripts that are almost just like aliasing grep -E and grep -F. Why is the GNU team suddenly so worried about these shell scripts? If the maintenance of these scrip

A more layman way to describe it that avoids too much over simplification is that these learning models try to group things and apply probabilities to sequences of groupings. E.g.; A word is a grouping of letters, try to find the sequences

More likely, I think it's that the first principles approach they have used to find this optimisation has applications in domains far outside of optimising matrix multiplications. Only because the Google paper crossed their desk did th

Even before Grothendieck's scheme theory, algebraic geometry was already pretty focused on varieties in rings of polynomials and other such constructions. The heart of the domain is still using abstract algebraic arguments to solve geo

I'd say they're more algebraic representations of regular geometries. Algebraic Geometry as a mathematical field is interested in solving highly non-trivial geometric problems (think, from differential geometry, functional analysi

I think math feels hard and unpleasant to most students because the way it is taught is often extremely outdated. In primary school for example, we learn maths by memorising times tables and solving thousands of basic arithmetic problems. T

It increases as the square of air resistance compared to traveling at low but constant speeds. But I find that when I'm driving at lower speeds I'm constantly stopping and starting for traffic. Around where I live there are many r

C defines an abstract computing model. It's not that CPU's work with 0 terminated strings. It's that the compiler will always ensure that 0 terminated strings make sense on any arbitrary architecture. If you're a hardwar

Hardware description languages also have tons of undefined behaviour. Electronics, in general, has physical conditions it can be in that will not resolve to a finite value in a finite amount of time.

If you wanted to be extremely careful, you might pass unsigned ints into a function by copy, and cast it as a signed int to perform arithmetic, then do a boundary check before returning a result to be assigned back to an unsigned integer. T

Constant speeds on the highway should be the most efficient forms of driving. The only force the motors need to generate is the force required to overcome air resistance, this is going to be true of both ICE and electric. The range dip may

With all measures that are applied in management contexts I find that the mistake people tend to make is that there is a linear relationship between the measure of work and the financial measures (revenue, profit, margin, etc.) Velocity s

C is designed with a computing model in mind (the way memory works, the way arithmetic operations work, the way addressing works etc.). And its language idioms are designed to fall strictly in line with that computing model. There's ve

For the most part, I have found that GeForce Now is not bandwidth limited. NVIDIA has spent a lot of time and money tuning the service to do clever dynamic upscaling locally on your machine to minimise the sort of block compression artifact

They often do have version and revision numbers. As well as final release numbers. I find the biggest issue is the lack of ability to trace the document forwards in the repositories. Usually an update will list which documents it updates bu

If I recall correctly, Linus doesn't like C++ because it introduces abstractions that take control away from the programmer and delegates it to the compiler. Over time this just reduces the performance of the kernel, and makes it harde

MATLAB is such a peculiar language. Using it often reminds me of using Prolog, although MATLAB does a good job of hiding its esoteric nature. Some of my early post-grad work was done in MATLAB and I remember having to find ways to collapse

Not a robotics expert. But my understanding of the effect of input/motion models on the state estimation of Kalman filters is that it conditions the error covariance of the state estimate. So, when the quality of measurements is very h

I'd argue that if the human sees a line that the computer didn't see any advantage of at all, then the engine is just wrong. The more likely outcome if the engine is 'correct' is that it sees the line but thinks an alter

Many developing markets don't necessarily have devices that are much older or lower spec. Look at Malaysia, Singapore, India, China, Taiwan etc. Many people upwards of middle class in these places have good access to reasonable devices

I think what many people in this thread are trying to stumble over is that the way a computer prunes moves and the way humans prune moves is qualitatively different. A computer prunes its moves from either an explicit or implicit (implicit

There's also an argument to be made about complexity. While the average home user in the past could with effort learn the ins and outs of a DOS system, there is no way the average home user would have the time, energy, or experience to

I think there is some confusion here between programming, which is a skill; and engineering which is the application of knowledge. Of course programmers don't need degrees, the same way that good builders, carpenters, electricians etc.
