I hope you won't mind my picking your brain: which MPSC ring buffer implementations did you find that does drop old items when full? I could only found implementations that are bas…

LOX is apparently MPL, so a bit easier to work with than Nyx' AGPL, but still at odd with the MIT/Apache2 combo that has become the norm in the Rust world.

Just curious, what kind of simulations do you work on (mission design?) and what libraries would you use in C++?

I can see why someone would prefer Typst over LaTeX when the source is written in Typst or LaTeX, but what are the advantages if your source document is in Markdown? Is there anyth…

Not a solution. Verification emails alone got a small web site I set up to be blacklisted within days. Most of the unwilling recipients presumably couldn't understand the language …

The producers of an MPSC queue may use an AtomicWaker::wake to signal to the consumer that a new item is ready. In this case all wake-ups are necessary (not spurious).

Another offender is AtomicWaker [1] which does the same on contention. [1] https://docs.rs/atomic-waker/latest/atomic_waker/

I needed to reflect Rust enums and went a bit further with that approach. All variants are wrapped in a decorated class, where the decorator automatically computes the union type a…

TBH I consider the C++ `std::chrono` as the worse possible design. `tai_clock::now` does not actually take into account leap seconds. Unless it does, who knows ("Implementations ma…

Oh yes, absolutely, GP got it backward and I went along with it...

While this doesn't change the essence of your claim, the problem is not with UTC timestamps but with Unix timestamps. UTC timestamps (HH:MM:SS) are actually unique because the extr…

I have always wondered about that. If optimizing repeated atomic loads is indeed allowed, waiting for a signal by spinning on an atomic load could loop forever. Yet I have the feel…

While I have frequently seen LabView used for instrument/hardware control, I admit I have never seen people use Simulink for that purpose. Is there a popular Simulink/Matlab add-on…

One may count electric propulsion as a "better" propulsion system, but sadly it was a poor fit for Juice due to the very tight power budget. Even with those gigantic solar arrays, …

Not only is the instruction set simple, but the clock-per-instruction cost is deterministic, so assembly code is ideal for real-time I/O. Just like GP, we found that we could often…

I you think the NASA Open Source License is bad, look at the default license for non-commercial, ESA-funded software [1]. The territorial limitations effectively prevents any form …

As others wrote, Pandoc is Haskell so it compiles to a fairly efficient binary. But more importantly, unlike the various Markdown flavors or AsciiDoc, it is incredibly extensible t…

> Two things can be true at the same time Yes, but it is not possible to assert that both are true at the same time with full certainty.

You are right of course, but I would contend that generating as well sub-normal floats is in 99.9% of the cases a needless cost. The reason is that, more often than not, all this e…

This is a widely used method to map random integers to floating point numbers, but it has the disadvantage of wasting 1 bit of float mantissa precision. On modern CPUs, its computa…

To be clear, as mentioned in another thread [0] there is no need to ensure consistency between head and tail for a SPSC so storing them in different cache lines would be much bette…

Note that the second variant does not claim to be MPMC, only SPMC. Many lock-free structures use CAS loops. It would not be lock-free if a consumer pre-empted at the wrong time cou…
