64 + 48 * 4 == 256... still just five 64-bit words.

Yes, it complies with the as-if rule; there's no observable difference in behavior. This would apply as well for supporting 64 bit additions within a loop on 32- or 16-bit architectures, for example.

APUs have a common mode failure with main engines: lack of fuel. Are there designs out there which require emergency power after engine failure and don’t have a RAT?

An okay overview of some high level context for on-disk storage, but it's perhaps more useful to say that disk hardware (and memory hardware) present an abstraction of a bunch of bits. Even for DRAM, there isn't a one-to-one mappi

Yep. If you're generating them yourself, you'll probably want to be careful to follow the NACA method for combining camber and thickness profiles -- basically, running a circle of thickness-profile-defined diameter along the cambe

by addaon 1y ago
841220 is, sadly, not a legal NACA airfoil designator. There are three major families of procedurally-defined NACA airfoils -- four-digit like the 2412, five-digit like the 23012, and the 6-series like the 64A012. It looks like this site on

by addaon 1y ago
Also, it looks like you might have a bug in generating the airfoil shape. An airfoil like the 8412, while extreme, is well-defined and constructible from NACA-style combination of thickness and camber forms; but you show it as having a &quo

Unless you're planning to resolve the boundary layer and model separation (good luck...), you'd probably be better off using panel methods than NS. Look at XFoil or JavaFoil for available implementations.

Still quite common in NYC. There’s a bit of a social distinction between doorman buildings and elevator-man buildings, and some people prefer the latter.
