Any of the integrated actuators on the market (e.g. Cubemars, zeroerr, myactuator, many more) do proper control and feedback.

In general implementing a weaker memory model (e.g. aarch64) on a stronger memory model (e.g. x86_64 or s390x) is fairly easy, while the reverse is more difficult (see Apple's processors which have a dedicated "stronger" mode

The "naive notion of system performance" is that the system is primarily operating in the ideal regime, and thus all deviations deserve alerts (and receive attention). The reality is that often the system is operating often enough

Either they believe their own hype and their reliability is a reflection of the real weaknesses of AI coding, or they're complete liars and doing far more traditional SWE than they claim. I think the former case is far more likely and

To a first approximation, basically no one in the industry does. Users regularly report performance regressions in basically every major piece of software, most of which would have been caught by performance testing.

Indeed, regulation is the only way to protect passengers from market greed here, but the airplane makers play a critical role in what designs they make available to airlines. Airbus and Boeing both like to market their newer designs and int

Not covered: the inevitable even-smaller lavatory to further insult the dignity of the flying public. At this point, the designers of narrow-body interiors should be actively shamed for how hostile they have made lavatory designs. In a worl

If you look at larger multi-copters, 6 and 8 are quite common since they allow for some redundancy, allowing for safe landing and/or continued flight following the failure of one of the rotors. As other replies note, 4 is the simplest

Yeah, clean room implementation is the only way - and the route chosen by the aravis project that builds a FOSS implementation (which is a really great piece of software, way nicer to work with and easier to debug than the terrible vendor S

Because these bodies want to maintain a moat for the products made by member companies. No more, no less. A great example of this is the GigE Vision/GenICam standards that are used by basically all machine vision cameras, which were a

"Crews can't stop sweating on the flight deck" is exactly like saying "the middle east is hot and people sweat in the sun there". It has very little to do with the ships and everything to do with a climate that is

Satellite launch is so much easier than storable SAM/ABM, the comparison is not really useful.

No, if a process allocates an infeasible amount, malloc fails and the process needs to deal with the failure (which is what already happens, "malloc doesn't fail on Linux" is only really true for smaller-than-page-size alloca
