How to install numpy on M1 Max, with the most accelerated performance (Apple's vecLib)? Here's the answer as of Dec 6 2021.
So that your Python is run natively on arm64, not translated via Rosseta.
$ bash Miniforge3-MacOSX-arm64.sh| #!/bin/bash | |
| clang hello.c -target arm64-apple-darwin20.1.0 -o hello.arm64 | |
| echo -n "hello.arm64 is architecture " && lipo -archs ./hello.arm64 | |
| clang hello.c -target x86_64-apple-darwin-macho -o hello.x86_64 | |
| echo -n "hello.x86_64 is architecture " && lipo -archs ./hello.x86_64 | |
| lipo hello.arm64 hello.x86_64 -create -output hello | |
| echo -n "final output binary has archs " && lipo -archs ./hello |

| // Basic instrumentation profiler by Cherno | |
| // Usage: include this header file somewhere in your code (eg. precompiled header), and then use like: | |
| // | |
| // Instrumentor::Get().BeginSession("Session Name"); // Begin session | |
| // { | |
| // InstrumentationTimer timer("Profiled Scope Name"); // Place code like this in scopes you'd like to include in profiling | |
| // // Code | |
| // } |
It's a common confusion about terminal colours... Actually we have this:
printf "\x1b[${bg};2;${red};${green};${blue}m\n"

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).
It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
