cool that nix gets a special flag to support their very specific dependency model
# Always patch binaries for usage with Nix toolchains. If `true` then binaries
# will be patched unconditionally. If `false` or unset, binaries will be patched
# only if the current distribution is NixOS. This option is useful when using
# a Nix toolchain on non-NixOS distributions.
#build.patch-binaries-for-nix = false
it might be "useful" to support other toolchains too
well i like that they aren't unconditionally sending the telemetry remotely
# Collect information and statistics about the current build, and write it to
# disk. Enabling this has no impact on the resulting build output. The
# schema of the file generated by the build metrics feature is unstable, and
# this is not intended to be used during local development.
#build.metrics = false
although the unconditional bootstrap downloads are a form of telemetry already
but pipeline problems are different, for all the above reasons! the online and interdependent properties motivate using parallel threading when the source and sink of a data flow are meaningfully distinct. copying a file onto the same filesystem can often be done with a single syscall, but writing it into a network request requires buffering, even if the OS can cheat there too. that's because the filesystem and the network depend on distinct hardware resources!

oh my god that's 273M with xz compression. zero effort. negative effort
literally so close to getting it
# Set the bootstrap/download cache path. It is useful when building rust
# repeatedly in a CI environment.
#build.bootstrap-cache-path = /path/to/shared/cache
what if we had a method to cache outputs that are shared across invocations of the bootstrapping process. what if?

Ok, I have to correct myself:
Compiling any C/C++ project on Windows is an absolute clusterfuck!
I've now almost spent more time trying to compile my program for Windows than writing the actual code for it - let that sink in!

Good news in hard times.
"Peak Energy just shipped the US’s first grid-scale sodium-ion battery"
Good news because we must transition off carbon fuels now, and good news because its not scarce or hard to mine, or behind some prick's tariff wall, its not dirty, won't burst into flames.
Because its salt. Like sunlight, its EVERYWHERE.

Je n'avais jamais pensé au fait que les navigateurs web modernes incluaient un parser XML et un système de transformation basé sur XSLT. Ca ouvre des perspectives fascinantes (même si vieilles de 25 ans) https://github.com/pacocoursey/xslt #xml #xsl #web #build
