In Whatsapp, are the same private keys used in all my devices? Is the sharing of the keys from scanning the QR code on the web browser to link to my device? Thank you!

For a custom MCU driven boost converter I'm trying to drive a power MOSFET IRF520N at 700kHz. In order to reduce RdsOn and switching losses I have added a logic MOSFET 2N7000 to drive the gate at 12V from a 3.3V PWM signal. The power MOSFET gate is pulled up by a low value resistor in order to re...

I am new to GIS and PostGIS. I have an existing legacy database table with millions of rows and a geometry column. It has a mix of points like this: I wish to sort the rows based the size of the geometry column. I suspect that someone put a map of the US in one of the rows and it doesn't belong ...

We are driving a piezo transducer array with sub-1 μs pulses at an extremely low duty cycle. A single N-channel power MOSFET drives each transducer. Each power MOSFET transistor has a low side gate driver (FAN3229T) ahead of its gate to slew it quickly. The transducer drive is not push-pull: ther...

Today I learned that the correct/recommended form of English, only a few centuries ago, required using "more" and "most" together with adjectives that were already in (respectively) comparative or superlative form, such as "more better" or "most worst". Ben Jonson's The English Grammar (1640) sai...

I have a MacBook Pro with macOS Ventura 13.0. In System Settings -> General -> Login Items, I discovered that a random Charlie Stigler item was running in the background. I have no idea what this is.

Non negative least square solves $$ y = \alpha^T x \\ s.t. \forall i,~ \alpha_i \geq 0 $$ However, I would like to apply the non negativity constraint only on some coefficient, say only the $\alpha_i,~ \forall i \in \mathcal{S}$. This is not possible using scipy's nnls function. However, I think ...

Excuse my poor English, I speak French. Core Collapse in a Self-Gravitating System • Suppose that there was no energy generation in the core. The pressure would still be high, so the core would be hotter than the envelope. • Energy would escape (via radiation, convection…) and so the core would s...

I'm running Windows 11, and whenever I hit my Esc key twice, it closes the active window. I would like to disable this feature, and have not been able to track down how to do so. What's causing this?

I'm trying to understand bilinear forms and how they can be 'equivalent' and how this 'equivalence' translates to their associated orthogonal groups. Fix a field $F$.

The sequence of polynomials $$P_n=\sum_{k=0}^{\lfloor(2n-1)/3\rfloor} \frac{(2n-2k-1)!(2n-2k-2)!}{k!(n-k)!(n-k-1)!(2n-3k-1)!}x^k$$ satisfies apparently the identities $$0=\sum_{j=0}^nP_{n-j}(P_j-(-x)^j)$$ for all $n\geq 1$. (This has probably a WZ proof since it involves hypergeometric stuff.) It...

I just started watching the new Quantum Leap series, but as far as I can tell, there's been no mention of what happened to Ben's original body - or if there is a continuation of the Waiting Room concept from the original series.

This picture is part of a circuit designed to measure capacitance. The control circuit would apply +12V or -12V on "DTR pin 20" and the two resistors give a minimum and maximum voltage reference which is used to compare with the charging/discharging capacitor's voltage. The book says T1 & T2 are ...

Given a set of substrings, such as [ca, ar, car, rd], it's possible to create infinitely many strings by concatting them together.

A function $f:\mathbb{R}\rightarrow \mathbb{R}$ has a removable discontinuity at a given real $x$ in case the left and right limits are equal but not to the function value, i.e. $f(x+)=f(x-)$ but $f(x)\ne f(x+)$. Which function classes consist of (possibly discontinuous) functions that do not hav...

This question is about addition of positive integers with more than one digit, a topic covered in second grade. But it's not really elementary.

I’m taking an intermediate microeconomics course in college and just got to the topic of monopolies. I know the concept of a Giffen good.

Suppose there's a dataset that has features like the weight and height of people.
