Also: While SIMD does not execute additional instructions, it executes more operations [that's the whole point; it reduces contention and bandwidth needs in the frontend / instruction decoding and scheduling]. A Haswell core peaks

CPython only does very few optimizations on the byte code. Most optimizations are in the interpreter itself.

You very well captured the intention of this (or at least what I think is the intention). I mentioned above that in highly abstracted systems it is not at all unusual to spend more time with inefficiencies rather than doing real work: You n

Well the obvious answer would be, eliminate the loop, which is what any compiler optimizer will do ;) But let's assume that the operation is not quite so trivial like here, then this structure would be a prime example where each loop o

Actually TCP over web sockets [over TLS] over TCP. How's your buffer bloat? — Fine, how's yours? — Great, thanks for asking!

It doesn't really matter what they do, since filesystem naming is FUBAR and has been FUBAR pretty much since UNIXv1, and possibly even earlier than that outside the UNIX family.

This is not a bug in either, it's a configuration defect. NTFS-3g used with the correct options, namely windows_names, works exactly as expected, but is then not POSIX compliant anymore.

Maybe, but what would be the point? I knew Qt already (although it's pretty easy to get started), and the UI of the application was quite complex and even with Qt had some custom, complex UI widgets (a node-graph editor, keyframing wid

InnoSetup was very easy to get started with and get the expected results, while NSIS looked more complex. I'm not particularly opinionated about installers as long as they install and uninstall things :)

In 2012 I could pack a whole Python interpreter, Qt and various image-processing libraries into an InnoSetup installer that just-so scratched the 12 MB mark; I doubt this has changed significantly. Contrary to what the linked (more interest

Factually incorrect, since Qt uses native widgets when possible. Applying Qt stylesheets usually disables use of the operating system's styling engine, i.e. only then Qt starts drawing the widgets by itself. Widgets that are not part o

"Fractional scaling" (I assume you mean e.g. 160 DPI instead of 200 DPI) is no problem even with the older KDE version from F23, just a bit finicky to get started up - but when it runs, it works. Gtk on the other hand seems (seeme
