Imo there's an identifiable core common to all of these kinds of package managers, and it's not terribly hard to work out a reasonably good hierarchical ontology. I think OP's greater insight in this section is that internally, every package manager has its own ontology with its own semantics and lexicon:
> Even within a single ecosystem, the naming is contested: is the unit a package, a module, a crate, a distribution? These aren’t synonyms. They encode different assumptions about what gets versioned, what gets published, and what gets installed.
Indeed. It's hard to see why eg. a prog language would need its own package management system.
Separate mechanics from policy. Different groups of software components in a system could have different policies for when to update what, what repositories are allowed etc. But then use the same (1, the system's) package manager to do the work.
I don't disagree that it would be nice if there was more interoperability, but so far I havn't seen anyone even try to tackle the different needs that exist for different users. Heck, we really havn't seen anyone trying to build a cross-language package system yet, and that should be a lot easier than trying to bridge the development-distro chasm.
For example?
Normally with an system package manager you would have a -lib package for using in your own code (or simply required by another package), a -src, and then a package without these suffixes would be some kind of executable binary.
But with npm and pip, I'm never sure whether a package installs binaries or not, and if it does, is it also usable as a library for other code or is it compiled? (Homebrew as you mentioned is source based but typically uses precompiled "bottles" in most cases, I think?) And then there is some stuff that's installed with npm but is not even javascript like font packages for webdev.
The other interesting thing about these language package managers is that they complete eliminate the role of the distribution in packaging a lot of end user software. Which ironically, in the oldest days you would download a source tarball and compile it yourself. So I guess its just a return to that approach but with go or cargo replacing wget and make.
The uneven terrain also makes package managers more interesting to compare to each other than many other kinds of software, imo.
"but bun!" — faster shovel, same hole
People love to complain about node_modules being a black hole but that size bought JS land an advantage that’s not very common among popular languages.
This is mostly good, but version lock does encourage packages to accept wide ranges of dependencies, and to update their dependency ranges frequently, instead of just sitting there on old versions.
Version hell is a thing. But Nix's solution is to trade storage space for solving the version problem.
And I think its probably the right way to go.
I found Eelco Dolstra‘a doctoral thesis (https://edolstra.github.io/pubs/phd-thesis.pdf) to be a great read and it certainly doesn’t paint the picture of a wicked problem.

It is unfortunately one of the most thankless tasks in software engineering, so these are not applied consistently.
This was symbolized quite nicely by google pushing out a steaming turd of a version 1 golang package management putting while simultaneously putting the creator of brew in the no hire pile coz he couldnt reverse a binary tree.
In this respect it is a bit like QA - neglected because it is disrespected.
What makes it seem like a wicked problem is probably that it is the tip of the software iceberg.
It is the front line for every security issue and/or bug, especially the nastiest class of bug - "no man's land" bugs where package A blames B for using it incorrectly and vice versa.
For tree reversal in particular, it shouldn't be any harder than:
1. If you don't know what a binary tree is then ask the interviewer (you probably _ought_ to know that Google asks you questions about those since their interview packet tells you as much, but let's assume you wanted to wing it instead).
2. Spend 5-10min exploring what that means with some small trees.
3. Then start somewhere and ask what needs to change. Clearly the bigger data needs to go left, and the smaller data needs to go right (using an ascending tree as whatever small example you're working on).
4. Examine what's left, and see what's out of order. Oh, interesting, I again need to swap left and right on this node. And this one. And this one.
5. Wait, does that actually work? Do I just swap left/right at every node? <5-10min of frantically trying to prove that to yourself in an interview>
6. Throw together the 1-5 lines of code implementing the algorithm.
It's a fizzbuzz problem, not a LeetCode Hard. Even with significant evidence to the contrary, I'd be skeptical of their potential next 1-3 years of SWE performance with just that interview to go off of.
That said, do they actually know that was the issue? With 4+ interviews I wouldn't ordinarily reject somebody just because of one algorithms brain-fart. As the interviewer I'd pivot to another question to try to get evidence of positive abilities, and as the hiring manager I'd consider strong evidence of positive abilities from other interviews much more highly than this one lack of evidence. My understanding is that Google (at least from their published performance research) behaves similarly.
Supply chain vulnerabilities are a choice. It's a problem you have to opt in to.
That's simply not true; it doesn't come down to "monorepo-or-not?"
It comes down to whether or not the code size of an app's dependencies and transitive dependencies is still reasonable or has gotten out of control.
The trend of language package managers to store stuff out of repo (and their recent, reluctant adoption of lockfiles to mitigate the obvious problems this causes*) is and always has been designed to paper over the dependency-size-is-out-of-control problem—that's the reason that this package management strategy exists.
You can work on dozens of projects (unrelated; from disjoint domains) that you maintain or contribute to while having all the source for every library/subroutine that's needed to be able to build the app all right there, checked into source control—but it does mean actually having a handle on things instead of just throwing caution to the wind and sucking down a hundred megabytes or more of simultaneously over- and under-engineered third-party dependencies right before build time.
It's no different from, "Our app consumes way too much RAM", or, "We don't have a way to build the app aside from installing a monstrously large IDE" (both belonging to the category of, "We could do something about it if we cared to, but we don't.")
> There is actually a huge difference between checking in all of your dependencies and checking in a lock-file.
Yes, huge difference indeed: the hugeness of YOLO maintainers' dependency trees.
* what could possibly go wrong if we devise a scheme to subvert the operations of a tool where the entire purpose of it was to be able to unambiguously keep track of the revisions/content of the source tree at a given point in time?
This is not a technical problem. It’s a cultural one.
Certainly Go is a more rigorous language than say JavaScript but it’s package mangement was abysmal for years. It’s not even all the great now.
C/C++ is the same deal. The way it handles anything resembling packages is quite dated (though I think Conan has attempted to solve at least some of this)
I think Cargo and others have the hindsight of their peers, rather than it being due to any rigorous attribution of the language
Frankly, PHP also has a very good packet manager with Composer. In general, PHP has done surprisingly good and sane decisions for the language and extremely solid support for static typing by now.
But yeah, Cargo definitely had the benefit of Hindsight.
The real problem is that system package managers need to be made easier to use and have better documentation, so that everyone stops trying to reinvent the wheel.
Apps don't support system package managers, system package managers package apps.
The problem is that this should be easy. Given a written description by the app developer of what files the app needs to be installed and what its dependencies are, writing a packaging metadata file for any given package manager should be less than ten minutes of work for the packager, and anybody should be able to learn how to do it in less than a day.
But the packaging systems are poorly documented and in some cases unnecessarily complicated, and then getting someone to add your app to any given package manager is more work than it should be and app developers start trying to figure out how to package it themselves instead of getting on with just developing their app.
> Getting away from that is the main feature that drive adoption of language specific managers.
> What is needed is a layer in between that work well with both languages and systems.
That's what system package managers are.
I hate package management so much. I hate installing unnecessary cruft to get a box with what I want on it.
It makes me pine for tarballs built on boxes w/ compilers installed and deployed directly onto the filesystem of the target machines.
Edit: I'd love to see package management abstracted to a set of interfaces so I could use my OS package manager for all of the bespoke package management that every programming language seems hell-bent on re-implementing.
These (typically) operating system repos have oversight and are tested to work within a set of versions. Repositories with public contribution and publishing don't have any compatibility guarantees, so the cruft described in the article must be kept indefinitely.
Unfortunately, I don't think abstracting those repositories to work within the OS package ecosystem would solve that problem and I suspect the package manager SAT solvers would have a hard time calculating dependencies.
re: interpreted languages, though, I think it's still a shit show. I don't want to run "composer" or "npm" or whatever the Ruby and Python equivalents are on my production environment. I just want packages analogous to binaries that I can cleanly deploy / remove with OS package management functionality.
You're effectively describing Gentoo.
Just a personal opinion but it's awesome.
Programming languages: Cargo
Nothing against systemd, but hardwaring is not a good idea in that regard.
With guix, you at least install things in a container.
sadly, guix also went the non-conda-route, so you could not use it as a conda replacement only :(
None of the other pip replacements were actually good software like uv
If this is a wicked problem, then so is much of other real-world engineering.
There was a time when this was sufficient. We've moved well past that point.

That said, feature creep is absolutely a killer. And it is easy to see how these will stack on each other where people will insist that for this project, they need to try and reinvent the state of the art in solvers to get a product out the door.

1. It's a joke. The hyperbole is intentional, but it does communicate something relatable.
2. You don't need a citation. Probably anyone with enough software development experience understands the substance of the claim and understands that it is (1).
