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.

Securizing your GitHub org
Fortunately there is a great free online tool that help you by doing all the hard work (it will open a pull-request and automatically fix issues).

Compromised PyTorch-nightly dependency chain December 30th, 2022
If using GitHub Actions for CI/ CD, Harden Runner (https://github.com/step-security/harden-runner) can be used to audit and block DNS exfiltration. Outbound calls from CI are predictable (to source repo, artifact registry, etc.) and don't change often.

Attack Simulator for SolarWinds, Codecov, and ua-parser-js breaches
As part of writing tests for Harden Runner GitHub Action, which prevents such attacks, there was a need to write attack simulator for these attacks.

py-template: one-click extensive GitHub Actions pipelines for your Python projects!
I am not too familiar with GitLab, to be honest, but: - Commit/PR linting (to be in tandem with semantic versioning) is implemented via third-party GitHub Actions (https://github.com/amannn/action-semantic-pull-request and https://github.com/wagoid/commitlint-github-action), these might be hard to transfer - Blocking egress to mitigate supply chain attacks is performed by step security’s Harden Runner (https://github.com/step-security/harden-runner), you may raise a question there about GitLab support - CodeQL support is GitHub only AFAIK (but you would have to verify it)

Securing a GitHub repo is a ton of work
I've found StepSecurity's tooling helpful in getting my repos secured.

Sigstore
I agree. There are projects such as https://github.com/ossf/package-analysis and https://github.com/step-security/harden-runner that do behavior analysis. Disclaimer: I’m maintainer of the second one.

Best practices to keep your projects secure on GitHub
So if you are concerned about this, I'd suggest looking at the following:
* OpenSSF Scorecard Action - https://github.com/ossf/scorecard#scorecards-github-action
* Step Security Harden Action - https://github.com/step-security/harden-runner
I realize that this means trusting these providers but they seem at least tacitly blessed by GitHub. https://docs.github.com/en/actions/security-guides/security-...

Video of malware node packages trying to phone home
Few hours back several malicious packages were released on npm registry. This video shows how some of these packages are making outbound calls as part of the preinstall step when executed in a GitHub Actions workflow.

Tree-shaking, the horticulturally misguided algorithm
A lazy chunked delivery strategy like used in the k8s stargz-snapshotter[0] project could be effective here, where it only pulls chunks as needed, but it would probably require wasm platform changes.

Show HN: depot.ai – easily embed ML / AI models in your Dockerfile
To optimize build speed, cache hits, and registry storage, we're building each image reproducibly and indexing the contents with eStargz[0]. The image is stored on Cloudflare R2, and served via a Cloudflare Worker. Everything is open source[1]!
Compared to alternatives like `git lfs clone` or downloading your model at runtime, embedding it with `COPY` produces layers that are cache-stable, with identical hash digests across rebuilds. This means they can be fully cached, even if your base image or source code changes.
And for Docker builders that enable eStargz, copying single files from the image will download only the requested files. eStargz can be enabled in a variety of image builders[2], and we’ve enabled it by default on Depot[3].
Here’s an announcement post with more details: https://depot.dev/blog/depot-ai.
We’d love to hear any feedback you may have!

A Hidden Gem: Two Ways to Improve AWS Fargate Container Launch Times
Seekable OCI (SOCI) is a technology open-sourced by AWS that enables containers to launch faster by lazily loading the container image. It’s usually not possible to fetch individual files from gzipped tar files. With SOCI, AWS borrowed some of the design principles from stargz-snapshotter, but took a different approach. A SOCI index is generated separately from the container image and is stored in the registry as an OCI Artifact and linked back to the container image by OCI Reference Types. This means that the container images do not need to be converted, image digests do not change, and image signatures remain valid.

Speeding up LXC container pull by up to 3x
This is interesting and seems general purpose. Not merely for container images.
There’s this option for OCI containers which I don’t pretend to understand: https://github.com/containerd/stargz-snapshotter
It is used by containerd and nerdctl. You do have to build the image with it. Images work in OCI compatible registry. By fetching most used files first container can be started before loading is finished. Or so I gather.

Optimizing Docker image size and why it matters
stargz is a gamechanger for startup time. You might not need to care about image size at all
kubernetes and podmand support it, and docker support is likely coming. It lazy loads the filesystem on start-up, making network requests for things that are needed and therefore can often start up large images very fast.
