I read about this story in Horowitz, Hill : "The Art of Electronics" chapter on negative feedback. You can find an old edition freely available here: https://archive.org/details/TheArtOfElectronics/Vol-1&

I will respectfully disagree about opamp feedback loops being recursion. It is almost magical but I do not see any recursive nature in it. You can't compute fib(n) recursively with O(1) transistors. Maybe if you use the non-recursive e

More like compile once and distribute one blob, run anywhere. In theory. Write once, run anywhere is true with cross compilers and native executables without any bytecode intermediate formats. Or even things like APE executables and cosmopo

This is uniform across Europe, it's 30 days from a positive test to have comparable numbers. That isn't very reliable any more as testing is reduced and not comparable from country to country (it was more reliable in 2020). The &q

This could've been very useful to me when setting up some cross compiler targets in a Rust project. I burned through my almost all of my 3000 actions minutes in no time at all. Had to put my project on a hiatus until the next billing p

I think you are vastly overestimating the willingness and capability of volunteers and underestimating the effort needed to coordinate such an effort. And having any kind of manual intervention required will almost certainly reduce the reli

I work as a software developer in a hardware company. We have A LOT of tests. But testing costs a lot more when there is hardware present. It's a whole new dimension in your testing matrix. You can't run on cloud provider CI. Hard

These blessed "system components" do not exist any more. Windows has two or three different ways of doing widgets and so does MacOS while the Unix land never had one. You can still use the old ones, but they will look old and may

Perhaps, but it's also much better than it was two years ago and there is work going on to make it better two years in the future. A myriad of experimental prototypes (like the failure crate and its descendants) have been made, experim

For simple tasks you can get away without any external crates by using `Result<T, Box<dyn Error>>`. But it's much more comfortable to use thiserror or anyhow in the long run. fn read_string() -> std::io::Result<

You will not distinguish an echo, just a change in the "tone" of the sound you make as it reverberates in your surroundings. The echo pulses are there but just milliseconds after the sound you made. It will all blur into a softer

I have practiced echolocation for fun. Getting some basic awareness from your surroundings is not that difficult, like detecting if there is a wall on your left or right side. The difference in the sound response is subtle but clear. It&#x2

Cursor needs to be between double quotes (e.g. inside string literal) for ci" to work. See `:help text-objects`.

The keybindings are pretty similar, the paradigm change from verb-noun to noun-verb and the multiple cursor paradigm are bigger changes. I got used to it with my brief affair with Kakoune. The Vim muscle memory will be quite helpful and not

Make sure you have rust-analyzer installed, and check `hx --health` to see that Helix finds it. Not sure if this is still necessary, but I needed this workaround in ~/.config/helix/languages.toml: language-server = { co

They not only change the keybindings, they change the editor paradigm from a verb-noun model (dw = delete word) to a noun-verb (wd = select word, then delete) model. Multiple cursors also have an effect. It's pretty close to vim keybin

Here's a life changing tip to avoid this kind of issues with GDB: use the extended-remote mode. Open two terminals (e.g. in tmux), and in the first one run the GDB server. $ gdbserver --multi :5555 In the second terminal, open

If this act of sabotage was not conducted by nation state actors with submarines, but someone using fishing boats and scuba divers instead like you suggest, the perpetrators will be caught in a manner of days. The straits between the coasts
