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.

Using GitLab Kubernetes Runners to Build Melange Packages
Recently, I came across Chainguard and wrote the article How to build Docker Images with Melange and Apko. As a fervent supporter of Kubernetes and GitLab CI, I was eager to experiment with building images using Melange in this particular setup. GitLab's shared Runners work seamlessly with Bubblewrap, eliminating the need for additional configurations. This post is intended for enthusiasts like myself, interested in hosting their own Kubernetes Runners and leveraging the Kubernetes Runner Type of Melange.

A Study of Malicious Code in PyPI Ecosystem
```
This is basically manually invoking what Flatpak does:
https://github.com/containers/bubblewrap
This is also useful for more than just security. E.G., you can test how your app would behave on a fresh install by masking your user configuration files. I personally also have a tool that uses it to basically bundle all dependencies from an entire Linux distribution in order to make highly portable AppImages— Been meaning to post that, will get around to it eventually maybe.
The flags above should hide your user data (`--tmpfs`), disable network access (`--unshare-all`), hide/virtualize devices and OS state (`--dev` and `--proc`), and make the rest of the root filesystem read-only (`--ro-bind`— Including the insecure X11 socket in `/tmp`, which you might want to expose for GUI apps).
Check them against `bwrap --help`; I might have omitted one or two more things you'd need.

While trying to find out more comparison information, found this light on details issue:

It mentions nsjail and minijail.

Sandboxing All the Things with Flatpak and BubbleBox
bubblewrap is designed as a low-level too. There is nothing quick and dirty about it. It disallows everything by default and you have to be explicit about what you want to share with the host. If your application needs complex permissions/resources, then you will need to have a complex bubblewrap command line.
Once you have figured out which permissions/resources you need for a given program, you can wrap the command line invocation in a shell script.
If you want other people to do the work of defining permissions/resources, then have a look at firejail: https://github.com/netblue30/firejail

Ask HN: What are some unpopular technologies you wish people knew more about?
Firejail is cool: https://github.com/netblue30/firejail
Linux namespaces/cgroups but nowhere near as heavy as Docker.
I use it when I want to limit the memory of a Python script:

Toolship: A (More) Secure Workstation
Firejail can also be a useful option, though no good if you're on Mac https://firejail.wordpress.com/
Uses the same Linux primitives as docker etc, but can be a bit more ergonomic for this use case

Firejail: Light, featureful and zero-dependency security sandbox for Linux
Firejail, Flatpak (which uses Bubblewrap under the hood), and Snap (which uses AppArmor) all use the same underlying technology: Linux namespaces.
This question comes up a lot, and has been answered here: https://github.com/netblue30/firejail/wiki/Frequently-Asked-...
TL;DR: Firejail has much more comprehensive features than Flatpak (Bubblewrap). Firejail also has more comprehensive network support, support for AppArmor and SELinux, and easier seccomp filtering.
Compared to Snap (which uses AppArmor), Firejail is compatible with AppArmor and again goes above and beyond with a lot of additional features.

Bubblewrap – Low-level unprivileged sandboxing tool used by Flatpak
Wonderful little tool, too bad you must chain various exec calling tools to get cgroups (a bit akin to `ionice ... nice ... cmd`) and Linux users namespaces can't allow UNIX sockets while preventing network access (I think?).
Migrated from Firejail when its complexity annoyed me too much and I hit https://github.com/netblue30/firejail/issues/3001 (Firejail doesn't like parens or brackets in --put/--get parameters) to a badly NIH version using bwrap and bash to have "profiles":
- Firejail: Light featureful and zero-dependency security sandbox for Linux

Do, or do not. There is no try
Firejail does this. The profile database is the two "profile" directories in https://github.com/netblue30/firejail/tree/master/etc
