Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Malicious libraries can steal all your application secrets in Elixir
I used E in the 90s: http://erights.org/
I haven't kept up with newer systems but I've heard of https://github.com/endojs/endo and just came across http://reports-archive.adm.cs.cmu.edu/anon/home/anon/isr2017... (which says "in the style of the E programming language" -- that's as far as I've read) while looking that up.
WebAssembly was designed to follow the same capability security principles. CHERI too as someone else just brought up.

Building an Extension System on the Web
There are other potential solutions I haven’t explored close enough (like Endo and SES), or completely omitted as they’re based on an imperfect blacklist-based approach to security (like sandboxed WebWorkers). However, the mentioned 4 solutions are the top contenders, at least in my mind.

Harvesting credit card numbers and passwords from your site
I don't know why you are being silently downvoted, as I think it is worth talking about the potential of using static analysis to improve things.
One promising approach is Endo[0] which "uses LavaMoat to automatically generate reviewable policies that determine what capabilities will be distributed to third party dependencies."

Show HN: Run unsafe user generated JavaScript in the browser
Agoric moved forward and Realms gave way to SES

And Endo is a set of tools (being) built around it to make it more practical for particular usecases

Deno 1.26
Yea you could restrict the app by whitelisting only the network services and folders that it will use and that's pretty valuable though at least on Linux could already easily be achieved otherwise. It's good that Deno makes it easy but let's be honest, most people will just pass -A.
I'd love to see a permissions system on a library basis. It would ask the first time a dependency is added and when a new permission is requested after an update. Javascript doesn't make that easy though by being so dynamic. SES could maybe help: https://github.com/endojs/endo/blob/master/packages/ses/READ...

Node runtime that sandboxes all NPM dependencies by default
I was poking around on the internet a bit earlier and I found this project. It looks pretty cool, and I figured perhaps a few of y'all might find it cool too!
I have no idea if it actually sandboxes networking by default. This other project, endo[0], seems to add some of that functionality.
Regardless of the maturity though, it makes me excited to see this type of work getting done now!
(What made me want to research it was this[1] thread from the other day.)

Open source maintainer pulls the plug on NPM packages colors and faker, now what
Fortunately the problem could become more tractable if something like SES / Endo takes off:
"Endo protects program integrity both in-process and in distributed systems. SES protects local integrity, defending an application against supply chain attacks: hacks that enter through upgrades to third-party dependencies. Endo does this by encouraging the Principle of Least Authority. ... Endo uses LavaMoat to automatically generate reviewable policies that determine what capabilities will be distributed to third party dependencies."

Researcher hacks over 35 tech firms in novel supply chain attack
Yeah. JavaScript is probably the closest to being there (with things like SES[0], LavaMoat[1], etc.) but we're not quite there yet. It's just shocking that this sort of thing is as seemingly obscure as it is; it's like the whole industry has collectively thrown up their hands and said code execution is unavoidably radioactively dangerous. (While simultaneously using package managers that... well.) But it doesn't have to be!

Nix: The Breaking Point
I don't think so. The article is probably intended for the Nix community, so the author doesn't need to convince HN that something is going on. If as an outsider you are interested then you need to look into it yourself, the community has no obligation to make their internal conflicts legible to the outside world.
As an outsider myself, it certainly looks like something is going on as more than 20 Nixpkg maintainers left in a week: https://github.com/NixOS/nixpkgs/issues?q=label%3A%228.has%3...

NixOS Is Not Reproducible
Yes, Nix doesn't actually ensure that the builds are deterministic. In fact it works just fine if they aren't. There are packages in nixpkgs that aren't reproducible: https://github.com/NixOS/nixpkgs/issues?q=is%3Aopen+is%3Aiss...

The xz attack shell script
I'm not familiar with Bazel, but Nix in it's current form wouldn't have solved this attack. First of all, the standard mkDerivation function calls the same configure; make; make install process that made this attack possible. Nixpkgs regularly pulls in external resources (fetchUrl and friends) that are equally vulnerable to a poisoned release tarball. Checkout the comment on the current xz entry in nixpkgs https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/comp...

Debian Git Monorepo
NixOS uses a monorepo and I think everyone's love it.
I love being able to easily grep through all the packages source code and there's regularly PRs that harmonizes conventions across many packages.
Nixpkgs doesn't include the packaged software source code, so it's a lot more practical than what Debian is doing.

From xz to ibus: more questionable tarballs
In this specific case, nix uses fetchFromGitHub to download the source archive, which are generated by GitHub for the specified revision[1]. Arch seems to just download the tarball from the releases page[2].
