Heh, I started coding (in python) when I was about 15. One of my nerdy interests that motivated it was "historical" crypto (vigenère, etc). But another one of the first things I wrote was a script that would factor quadratic equat

We often use stepped "reach gauges" for machine guards used in manufacturing and such: https://www.mcmaster.com/gauges/machine-guard-safety-gauges/ Not too expensive though.

Today, probably not. Historically? Definitely. It wasnt that long ago that bare assembly was still dominant in embedded, long after general computing. Somewhat obviously, assembly programs were closely coupled to the hardware. Nowadays C

Not all motherboards have built in wifi, which leaves the option of a USB external adapter or a PCIe card.

I am not familiar with the R ecosystem, but have you tried PoweredQuery? I had become my go-to for all sorts for all sorts of data munging in excel.

Encoding data in cell formatting is questionable practice.

Agreed. You can do regex via VBA but I really want a built-in cell function for regex search, regex extract, and regex replace.

Nim's new ARC gc, which will be default soon-ish in 2.0, does not have a "runtime" as commonly understood. It is fully deterministic, so it simply injects alloc/free calls in the generated code at compile time. It even h

Indeed. I run a university fablab/machine shop and we prohibit work gloves on all rotary tools (lathes, mills, press drill, bench grinders) and band saws due to drawing in risk. Not just gloves, but all long sleeves, long hair, jewelry

Not sure if saving money counts here, but several years ago, some HN comment linked the MMM blog, from which I learned about the importance of investing and specifically index funds.

I'm not a mathematician at all (mechanical engineer), but to me, "exact" sounds like "deterministic" as an opposition to stochastic. I though optimal conveyed the idea of "literally the best possible solution b

Regarding the model as an optional less confident input: I mostly know KFs from the third approach, control theory, state observers, state space representation, where the model is a central concept. Can you actually use KF without a model?

Yeah, a full faceshield is definitely advisable when using grinders. Powerful tools not to be taken lightly.

C++ has decent industry acceptance in embedded nowadays, or at least that has been my impression. After C++, rust is likely the most popular, quite a lot of effort has been put into running rust on embedded, see eg https://github

A bit late here, but by any chance, does anyone know of a similar site for non-english high-quality ebooks? Specifically, I'd really like to read some french classics in the original french. I know Project Gutenberg, but quality is var

> The Pico and Pico W are strange The pico competes exactly in the same world where Arduino does. The Arduino Uno still sells for 30$ despite a very old and limited AVR chip. Pico is a great deal compared to that, at 5$ for a double core

To be fair, that quote does say "it pays to overfit", which is the inverse of "picking signal from noise". I'm not convinced it actually pays, though.

Can you even control which version of python + external dependencies you get in a colab? Whatever you publish and works now will not necessarily work in a year or two (which is often how much time it takes to get a journal paper published).

FWIW I agree with you, but DT devs don't, which is their right to put in their free time to develop their software according to their own preferences.
