I think this view is too narrow; there is definitely need for fine-grained incremental build systems, even outside mono-repos. If you need to chase a bug into a more fundamental library, say libc, libpng, or your stack's favourite JSON

Maybe I'm misunderstanding you, but it looks like it is a PHP specific problem. Python does not have it. Of course at C level parameterised queries ("prepared statements") do not accept arrays. It would not make sense for t

For people wondering when this is needed: Go is one of the programming languages that makes syscalls directly, thus libeatmydata has no effect on it (being an LD_PRELOAD to the libc).

Yes, you should read the manuals and try it out, given how easy and cheap it is to play around with smaller-instance cloud servers. I also started writing a tutorial series for practitioners you can check out: https://github.com&

Applying the NixOS config requires root -- that's not what it's about. What I mean is that services can set other services' options, without you (the admin) having to to write such overrides manually.

You can override NixOS's predefined systemd settings from _outside_ using NixOS module options. This allows you to change default settings that are not optimal for your use case, without having to patch NixOS itself, or write your own

That's right! After spending 5 years to write the OS, if you can spare 1-2 additional days to write down your experience, it'll be extra useful.

I think there's a misunderstanding: Most people want to use the .a file from their Linux/package distro that provides static libraries, such as Alpine Linux or nixpkgs. Such package distributions just use the build system default

Many programming languages do not use Meson as a build system (examples: Go, Rust, Haskell). Some C or C++ projects may use autoconf or CMake, in which case you cannot use Meson subprojects either. Distros use `-Ddefault_library=both` or `=

Projects in other programming languages for which Meson is not a choice also want to link statically (thus need the `.a` file installed).

I was also disappointed by the recent removal of static linking support in GTK [1]. It worked for a long time and now was made impossible. The reason given was "don't want to support it". That would make sense if it was a mai

I often work on static linking with Nix. Creating statically linked end user programs that aren't minimal CLI utilities is not trivial. You need static linking working for all your dependencies (`.a` files) of all your recursive depend
