I've done something similar at $WORK for a small project in C++, and I found it extremely helpful in building trust in calculations. Once you do something like this it feels almost insane to do it the typical way where all the calculat

Custom mechanical keyboard firmware like QMK [1] and ZMK [2] support custom chords called "combos". Basically if the combo's set of keys is hit (within some timeout which defaults to 50 ms) then a specific keycode is sent. Yo

One of my favorite ChatGPT uses is voice chat during long drives as a pseudo, albeit interactive, podcast to learn about various technical topics at the edge of my knowledge base. This podcast generation is pretty amazing, but hopefully the

Really excited to see Rerun get fleshed out as time goes on. I've used it at $WORK in spare time to visualize multi-agent telemetry and event information for remote operated robotic systems. To me the most useful feature was actually j

Dual-redundant gets you error detection without correction whereas triple-redundant with majority voting can get you error detection with correction in the case that one fails. The error detection with dual-redundancy only works if one fail

Outputting vnlog, using those tools to filter, and then plotting using feedgnuplot have covered most of my visualization needs. https://github.com/dkogan/vnlog https://github.com/dkogan/feedgnuplot

Sure. I meant it more in the sense that there are some launch costs associated with the Mars Helicopter because it consumes mass budget. As to the SpaceX point. Yes, I think SpaceX is more efficient with their money than NASA, but this will

They can't exactly procure a bunch of parts and then call it a day. Lots of the cost is tied to the verification and validation. Then there's the system design, requirements engineering, trade studies, system integration, engineer

I'm surprised there isn't cross-linking amongst types? If the function listing is `Foo bar(const Baz& x) const` I'd expect `Foo` and `Baz` to be links to those type definitions.

If you haven't, you should explore domain-driven design (DDD). It's an explicit idea in that framework that a problem needs a "ubiquitous language" and an identified "bounded context" where the said language is

feedgnuplot [1] is wonderful for quick visualizations of data from the shell. Also great for decoupling visualization from CLI programs. [1]: https://github.com/dkogan/feedgnuplot

I guess I should have qualified my post, I did look at Screen (OP) and it definitely does more than just sharing a terminal. It also just reminded me of something I've done before (Screen -> screen -> tmux -> gotty, the mind i

I guess I meant to ask what they mean by dependency injection. A bare version is just passing dependencies as arguments and I can't imagine what is so egregious about that. Maybe they mean something more complicated?
