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.

What I learned from making a DNS client in Rust
I made one too https://github.com/ccouzens/dns-packet
The differences:
I followed this guide rather than the RFCs https://github.com/EmilHernvall/dnsguide/blob/master/chapter...
Mine isn't as polished. The command line parsing and output is more thrown together.
I hardcoded the packet identifier (it's not production code, and I'm only looking up one at a time).
I didn't use any bit manipulation libraries. I can see they would help because DNS packets don't line up their information with the byte boundaries.

5 Systems Programming Project Ideas
I highly recommend the Building a DNS server in Rust guide by Emil Hernvall on GitHub. This guide will walk you through how to implement the DNS server and recursive resolve.

Show HN: Bocker-compose, the missing layer to Docker-compose
A (joke?) one-liner I came up with while thinking about solutions to centralized container management across multiple SSH hosts. Shame on me.
The name is inspired by bocker [0], albeit this doesn't re-implement docker-compose in bash, I found it to be fitting enough.
I'd love to see someone come up with a smarter and/or shorter way to do this.

Barco: Linux Containers from Scratch in C
When I did a talk about docker I also wanted to show a bit of what it does under the hood without going through all the layers and without too much details. This ~120 lines of shell script is really good in providing just an intro into what's needed for containers: https://github.com/p8952/bocker/blob/master/bocker

Latest Zen Kernel......
i tried it and like the concnpt, but until it can be launched via a systemd userspace service (without previously manually booting it) among other problems i will keep using docker (or bocker)

The Staff Engineer's Path – Book Review
> But you couldn't reimplement podman in a few hundred lines of code.
You don't even need a few hundred: https://github.com/p8952/bocker
And then there's 'dokku' which IIRC, started as a bash version of Heroku.
> Not all ideas have the same quality.
They really do. I've heard all kinds of things in my career, but almost none I would want to dedicate a portion of my life building. Not because they are bad ideas or won't work, but because of the person with the idea or it just didn't interest me. Those people went on to be moderately successful (like hundreds of millions worth) but I'm glad I wasn't on that ride.

“Implement DNS in a Weekend”
Bocker is in this same category...docker clone in bash that's helpful in seeing what's really happening underneath with nsenter, namespaces, network bridging, cgroups, etc.

Ask HN: What is the best source to learn Docker in 2023?
Docker implemented in around 100 lines of bash: https://github.com/p8952/bocker
This is the most mindblowing example for enterprise security teams that think Docker is a new threat on a single tenant Linux host.
No, buddies, all this stuff is already there. If you were fine with your visibility before*, you're still fine. Go find a real problem while we play with our developer dopamine.
* NARRATOR: They shouldn't have been.

Containers are chroot with a Marketing Budget
Bocker[1] does a reasonably good job of showing the value of Docker was mostly in Docker hub.
[1] https://github.com/p8952/bocker
There is a cool project I've seen called "bocker" (https://github.com/p8952/bocker) which is something of a proof of concept of implementing Docker with bash, which speaks a bit to how Docker is indeed in many ways an amalgam of lower level primitives (such as chroot as you mentioned). Pretty neat!
