Inside me are two wolves.

One wants to tune my system to be as power friendly as possible.

The other wants to enable the profile guided optimization use-flags, O3 gcc setting in portage's make, and link time optimization.

The third cannot count.

@efi Okay, so I am running gentoo. One of the premises of the OS is that you can customize it more than just about any other distro.
The way it operates is that installing a package downloads the source code and compiles it. You can enable to disable features when installing using something called "use flags". If something is enabled, then that feature gets compiled into the program.

@efi The package manage is called "portage". You can give it options to pass to the compiler. Usually you pass O2, which is a great compromise between compile time performance and run time. O3 has more optimizations, but can break things, and might not always be faster.
Profile guided optimization compiles the program, then uses runtime data to recompile a faster binary, which doubles compilation time.

@efi Link time optimization is similar, except it looks for optimizations when linking libraries together. I understand this one less, but it is still an option.

Anyway, doing all three is commonly agreed to be a Bad Idea because of the instability, but in theory you can make things go zooooom.

And since I am the type of nerd who uses gentoo, the temptation is there.

Finally, wolves are a type of animal in the canis genus, and good unless you are a kitten. :P

@TakeV I like wolves and interpreters
I know when racket compiles a program it basically flattens the dependency tree so accessing properties from deeply nested library links has no extra cost, but that's all I know
I have made like six TIS-100 programs and concluded that the only low-level thing I can understand is bitwise ops

@efi There is this game you might be interested in checking out. It is called "Turing Complete", and the premise is that you build a computer from first principles, starting with NAND gates.
I learned so much about how computers and everything work from it, and it is amazing.


@TakeV I tried many times to figure out constructor, the Zachtronics flash game where you build logic gates on a breadboard simulator and my brain got fried after the first capacitor
linking nands is something I do not have the brainpower for, even if I know the principles

@efi That is fair. I think I appreciated the abstraction of this particular version, since you do not need to worry about voltage or components, and once you build a new component, you can reuse it without needing to recreate anything from scratch.
