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.

- Distroless: Language focused Docker images, minus the operating system

Docker, Linux, Security. Kinda.
That's how we get distroless. Distroless base images follow the same pattern as alpine base docker images, as in, less functionality while still keeping enough functionality to be able to do the job and minimize the attack surface. Minimizing a base image like this means that the base images are very specialized so we have base images for golang, python, java and the like.

Chainguard Images now available on Docker Hub
lots of questions here regarding what this product is. I guess i can provide some information for the context, from a perspective of an outside contributor.
Chainguard Images is a set of hardened container images.
They were built by the original team that brought you Google's Distroless (https://github.com/GoogleContainerTools/distroless)
However, there were few problems with Distroless:
1. distroless were based on Debian - which in turn, limited to Debian's release cadence for fixing CVE.
2. distroless is using bazelbuild, which is not exactly easy to contrib, customize, etc...
3. distroless images are hard to extend.
Chainguard built a new "undistro" OS for container workload, named Wolfi, using their OSS projects like melange (for packaging pkgs) and apko (for building images).
The idea is (from my understanding) is that
1. You don't have to rely on upstream to cut a release. Chainguard will be doing that, with lots of automation & guardrails in placed. This allow them to fix vulnerabilties extremely fast.

Using Alpine can make Python Docker builds 50× slower
> If you have one image based on Ubuntu in your stack, you may as well base them all on Ubuntu, because you only need to download (and store!) the common base image once
This is only true if your infrastructure is static. If your infrastructure is highly elastic, image size has an impact on your time to scale up.
Of course, there are better choices than Alpine to optimize image size. Distroless (https://github.com/GoogleContainerTools/distroless) is a good example.

Long Term Ownership of an Event-Driven System
The same as our code dependencies, container updates can include security patches and bug fixes and improvements. However, they can also include breaking changes and it is crucial you test them thoroughly before putting them into production. Wherever possible, I recommend using the distroless base image which will drastically reduce both your image size, your risk vector, and therefore your maintenance version going forward.

Minimizing Nuxt 3 Docker Images
# Use a large Node.js base image to build the application and name it "build" FROM node:18-alpine as build WORKDIR /app # Copy the package.json and package-lock.json files into the working directory before copying the rest of the files # This will cache the dependencies and speed up subsequent builds if the dependencies don't change COPY package*.json /app # You might want to use yarn or pnpm instead RUN npm install COPY . /app RUN npm run build # Instead of using a node:18-alpine image, we are using a distroless image. These are provided by google: https://github.com/GoogleContainerTools/distroless FROM gcr.io/distroless/nodejs:18 as prod WORKDIR /app # Copy the built application from the "build" image into the "prod" image COPY --from=build /app/.output /app/.output # Since this image only contains node.js, we do not need to specify the node command and simply pass the path to the index.mjs file! CMD ["/app/.output/server/index.mjs"]

MQTT turns 25 (and has taken over the world)
I remember reading about it on Jessie Frazelle's blog [1] almost ten years back. I don't think I'd discovered HN so it must have been via Hackaday or similar. I fantasized about how amazing it must be to not have to worry about the myriad issues that came with manually maintaining different deployment environments and dependencies. Unfortunately at the time I was stuck in a professional microcosm that ran on Microsoft products and _maybe_ RHEL under severe duress (with a serious aversion to `audit2allow` and liberal application of `setenforce 0` to boot). Things have been considerably smoother since I've been able to use Docker and containerd via k8s on a full-time basis.

Toolship: A (More) Secure Workstation
https://blog.jessfraz.com/post/docker-containers-on-the-desk... is the one I remember, a bit old but still useful to see how she does it.
Seems super painful and indirected for a nebulous gain to me, but find your joy however you want I guess

- does anyone use containers just on their personal laptop to run apps ?

Essential Software in Docker Containers
Some of my day-to-day software.
After knowing that saved Chrome passwords and cookies in Linux are not protected against malicious dependencies in our development environment or other apps in our system, I decided to run my core apps in Docker containers, where their data is not accessible without sudo, and a personal understanding of where stuff is being saved.
These docker containers are also an improved version of https://github.com/jessfraz/dockerfiles/
Contrary to the project above, docker-workspaces runs Chrome in a sandbox, encrypts keys with the help of an also dockerized gnome-keychain, and works in tandem with pulseaudio, so you can use wired headphones (i still need to add some dependencies for it to work with bluetooth headphones).
