One of the advantages Dymola had a few years ago was an extremely advanced vehicle dynamics toolbox, to the point where it is considered a standard for NASCAR [1]. This is one of the tool's originating claims to fame circa 2015-19 when

This is generally referred to as an acausal modeling environment - you don't need to bring the causality of mathematical relationships, just bring the relationships. There are several other tools in this space, not the least prevalent

Another up-and-coming solution is Julia's simulation ecosystem [1]. It is powered by the commercial organization behind the Julia programming language, which has received DARPA funding [2] to build out these tools. This ecosystem unifi

If you intend to explore OpenModelica you may also like ModelingToolkit.jl: https://docs.sciml.ai/ModelingToolkit/dev/ There is also a project by Hilding Elmqvist, who worked for Dassault on Dymola (the leading co

Modelica can absolutely be used for this, but there may not be a readily-available model created already. A generic stepper motor model is available here: https://ie.utcluj.ro/files/acta/2003/Number%202/P

Thank you for investigating this - I got scared when I saw what looked like an ephemeral URL!

I worked for YEARS (2019-2022) without this using a custom internal registry. Let me tell you - this would have saved so much time with dependency management, package updating, new environment setup...

I think the decision to factor out the `Memory` type from `Array` will pay increasing dividends for a while, as packages begin to use it in earnest.

Like all laws, there will certainly be those who evade compliance geographically. A well-written law will be looked to as a precedent or "head start" for new places that end up wanting regulatory functions. I feel like the EU and

Really cool camera and very nice set of soldering "demos", including without flux.

Memory is pretty weird with these - I find that my hands do most of the remembering, and my mind doesn't have to do much work. It must be a very individual thing - hope everyone is doing what works for them. And you're right that

Same thing - I put them in my shell. Here is the list I use: alias ga="git add" alias gaw="git add -A && git diff --cached -w | git apply --cached -R" alias gb="git branch" alias gbl="git branch -l

Our slow-but-steady concept is down the batteries and storage fork in the road you lay out. Some areas are too remote for infrastructure, so we just revisit and change batteries and cards periodically.

We use dedicated trailcam-like recorders that drop `.wav` files to a 256GB SD card for a few months on four "C" size batteries. Several sites are very remote (islands separated from mainland by several miles), and recordings are s

I collaborate on a project like this, but using a distributed network of a dozen or so dumb recorders within 50 miles of my house.

I am all about the hands used in this video! The bandage after getting hit by lightning is very immersive. I bet this video will have a Streisand-like effect [1] on the indicated capture scenarios. [1]: https://en.wikipedia.org&#

Just the other week I was thinking: the hardware store is my bolt lengthener. I had a bolt that was too short, and no means to make it longer. I simply went to the hardware store and got a replacement. Of course this encumbers all of the re

Agreed - this plays to how discounts attract people. I think an individualized "happy hour" could also be interesting, e.g. letting people pick the weekday they have discounted so they can form habits.

The on-schematic visualization of simulation results, as well as improved result viewer and on-the-fly calculation of quantities such as power, are awesome features.

The "press release" looks more like a final report for a microcontroller applications class than an actual press release.
