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.

Accelerate your local development environment with Tilt
The first is the load function which loads Tilt extensions. It's a way to expand the tool's features, and several are available. Here we are using docker_build_with_restart, which will update the container running inside our Kubernetes cluster.

Skaffold vs Tilt vs DevSpace
This is the central viewport into manual resource control and environment enhancement through the open-source extensions for Tilt.

Rancher Desktop, a Docker Desktop Replacement
Recently, I found Tilt [0] to be a good partner of mine to run "all services locally". It can be compared to "webpack (live-reloading, a lot of configuration possibilities) for backend". You want to run a bunch of services directly? Use local_resource()/local(). You have Procfile? There is procfile() function. You have docker-compose.yml with databases? You can run it too with docker_compose(). You want have Tiltfile and include them all-together? There is load(). You need some web-ui for frontend devs and a nice log browser? It is there too. You need to do some extra steps before running a service? You want to update your local cluster with newly built image on file save? No problem, tilt will do that with k8s_yaml() function. Tilt uses Titlfiles for configuration, which are written Pythonish Starlark language and you use them to run any specific logic there.
Also, I am not very lucky in having resemble 1:1 k8s cluster locally. You could be close but as long as you don't run already in cloud you will have different configuration (additional annotations, various quirks that do not exist in kind/k3s but they are on GCP). However, making dedicated dev environments in the cloud might be very costly and incur a lot of additional tinkering.

How to edit code on host and map changes to container files?
If `host` means your production/staging hosts or whatever, you should get out of that habit now. Look into something like tilt.dev or telepresence.io or any number of other solutions that help solve this issue. Doing it directly on any host is just a recipe for bad habits and disaster.

An Overview of Docker Desktop Alternatives
The article doesn't mention k3d (https://k3d.io/) which is a variant of k3s that runs in docker (rather than a VM) - very nice for k8s dev/test on developer workstations.
It integrates very nicely with https://tilt.dev/ also (another very useful tool for k8s related dev/test).

Docker slow on MacOS with Cross tool?
If this is an issue during development then you can use something like tilt with docker-compose to directly copy modified source inside container and incrementally build it. https://tilt.dev/

DevSpace - Development Environments in Kubernetes
Along similar lines, how about comparing Devspace to [Tilt](https://tilt.dev/)?

Release Radar • March 2024 Edition
Having been featured in our February 2023, and January 2024 Release Radars, Moby is the original Linux Container runtime. This new version adds a bunch of changes to the Docker CLI and Moby itself with additional features. There's bug fixes and enhancements, with the main thing for users to be on the look out for containers that were created using Docker Engine 25.0.0. These containers might have duplicate MAC addresses, and thus must be recreated. The same goes for those containers created with Moby 25.0+ and with user defined MAC addresses. Read up on all these changes in the release notes.

Choosing a Name for Your Computer
Formlabs does this as well for their 3d printers, my earliest encounter of this was when Docker started getting popular: https://github.com/moby/moby/blob/master/pkg/namesgenerator/...
- Docker Inc. refuses to patch HIGH vulnerabilities in Docker
-
Do not install Docker Desktop on GNU/Linux systems
Try to use moby instead since that is the engine in Docker.

Exploring Podman: A More Secure Docker Alternative
> Podman is designed to help with this by providing stronger default security settings compared to Docker. Features like rootless containers, user namespaces, and seccomp profiles, while available in Docker, aren't enabled by default and often require extra setup.
Seccomp has been enabled by default since 2015: https://github.com/moby/moby/pull/18780
It is true that Rootless isn't enabled by default but its "extra setup" can be done with a single command (`dockerd-rootless-setuptool.sh install`)

- Io_uring will be blocked by default on Docker

OpenZFS 2.2: Block Cloning, Linux Containers, BLAKE3
Perhaps.
Thing is, https://github.com/moby/moby/blob/670bc0a46c4ca03b75f1e72f73... is using https://github.com/mistifyio/go-zfs which features code like `out, err := zfsOutput("get", "-H", key, d.Name)` (Source: https://github.com/mistifyio/go-zfs/blob/master/zfs.go#L315) to get a single zfs property.
Somebody chose to use a library as abstraction that looks good but is implemented as a MVP (nothing wrong with that). "In the future, we hope to work directly with libzfs" should have raised an alarm somewhere, though.
