  • Creating a kernel is hard, Linux itself is not going anywhere.
    If all current maintainers suddenly disappear, several corporations, who heavily depend on Linux, will maintain their own forks, so we will get Google kernel for phones, Amazon kernel for datacenters, Valve kernel for gaming, and probably some European initiative kernel for PCs and laptops to do document editing.




















  • printf is superior and more concise, and snprintf is practically the only C string manipulation function that is not painful to use.

    Try to print a 32-bit unsigned int as hexadecimal number of exactly 8 digits, using cout. You can do std::hex and std::setw(8) and std::setfill('0') and don’t forget to use std::dec afterwards, or you can just, you know, printf("%08x") like a sane person.

    Just don’t forget to use -Werror=format but that is the default option on many compilers today.

    C++23 now includes std::print which is exactly like printf but better, so the whole argument is over.
