You don't get it because you have never felt uncomfortable in your own body. Your brain's perceived gender matches your physical sex characteristics. Wearing pants as a male or a dress as a female didn't feel "wrong" to you. For some, it does.
I'm at the level of finally understanding pointers, templates, and operator/function overloads and using them pretty effortlessly now. I looked at some Rust code. I'm not sure I have the brain plasticity to take that on at my age now without massive struggling.
A container is just an environment where it appears to any program running within it that it has full access to the computer, while in reality it's "jailed" and isolated from the rest of the system. The OS resources are shared with the container, instead of the hardware resources as in a virtual machine. There's no hardware being emulated. It's a beefed up version of a chroot.
I'm in my 40s, and finally decided to give C/C++ a serious go and try to learn them at a competent level after decades of putting it off, and now everybody wants to move to Rust.
This is why I enjoy programming libraries only I will ever use. "Do I need to account for user ignorance and run a bunch of early exit conditions at the beginning of this function to avoid throwing an exception? Naww, fuck it, I know what I'm doing."
// do stuff 100 times
for (int x = 0; x < 100; x++) {
do.stuff();
}
After compiling might look like:
1011 1100 1011 1011 and so on and so forth, which corresponds directly to cells in a memory chip being switched on or off, which are the instructions that get fed to your CPU to do everything your program does in the machine.
