rfcs VS spack

Nix with dynamic derivations (RFC92) could potentially beat this curse.

https://github.com/NixOS/rfcs/blob/master/rfcs/0092-plan-dyn...

See: A plan to stabilize the new CLI and Flakes incrementally https://github.com/NixOS/rfcs/pull/136

NixOS recently introduced "problem" infrastructure to deal with such problems more gracefully and explicitly:

https://github.com/NixOS/rfcs/blob/master/rfcs/0127-issues-w...

For some more context: Flawed as they are, Flakes solve a large number of problems Nix experiences without them. This is why I, and presumably many others, use them even in their current experimental state.

An RFC was recently accepted to commit to forming a plan towards stabilization of Flakes: https://github.com/NixOS/rfcs/pull/136

Personally, I don't believe there won't be any breaking changes, but I also believe that the stabilization of Flakes is still a ways away and hope that there will be a reasonable migration path.

NixOS needs to merge https://github.com/NixOS/rfcs/pull/133 to solve the issue

> Afterwards, Flakes itself and its CLI components can be stabilized. The final design of Flakes will also require another RFC.

That seems like Flakes are still quite a ways away.

    First, the non-Flakes CLI wll be stabilized, in phases.

> Are we talking about the same autotools?

Yes. Instead of figuring out how to do something particular with every single software package, I can do a --with-foo or --without-bar or --prefix=/opt/baz-1.2.3, and be fairly confident that it will work the way I want.

Certainly with package managers or (FreeBSD) Ports a lot is taken care of behind the scenes, but the above would also help the package/port maintainers as well. Lately I've been using Spack for special-needs compiles, but maintainer ease also helps there, but there are still cases one a 'fully manual' compile is still done.

> Suffice it to say, I prefer to work with handwritten makefiles.

Having everyone 'roll their own' system would probably be worse, because any "mysteriously failure" then has to be debugged specially for each project.

Have you tried Spack?

Well, good luck with that, cause it's broken.

Previous release miscompiled Python [1]

gh is available via Homebrew, MacPorts, Conda, Spack, Webi, and as a…

> I can't count the number of times I've seen people say "md5 is fine for use case xyz" where in some counterintuitive way it wasn't fine.

I can count many more times that people told me that md5 was "broken" for file verification when, in fact, it never has been.

My main gripe with the article is that it portrays the entire legal profession as "backwards" and "deeply negligent" when they're not actually doing anything unsafe -- or even likely to be unsafe. And "tech" knows better. Much of tech, it would seem, has no idea about the use cases and why one might be safe or not. They just know something's "broken" -- so, clearly, we should update.

> Just use a safe one, even if you think you "don't need it".

Here's me switching 5,700 or so hashes from md5 to sha256 in 2019: https://github.com/spack/spack/pull/13185

Did I need it? No. Am I "compliant"? Yes.

Really, though, the main tangible benefit was that it saved me having to respond to questions and uninformed criticism from people unnecessarily worried about md5 checksums.

In Spack [1] we can express all these constraints for the dependency solver, and we also try to always re-cythonize sources. The latter is because bundled cythonized files are sometimes forward incompatible with Python, so it's better to just regenerate those with an up to date cython.

You want to look at the tools used for HPC systems, these are generally very well tried and tested and can be setup for single machine usage. Remote access - we use ssh, but web interfaces such as Open On Demand exist - https://openondemand.org/. For managing Jobs, Slurm is currently the most popular option - https://slurm.schedmd.com/documentation.html. For a module system (to load software and libraries per user), Spack is a great - https://spack.io/. You might also want to consider containerisation options, https://apptainer.org/ is a good option.
