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.

i must be the only guy that understands certificates
cfssl is kinda outright better version of that.

SSL certificate problem: unhandled critical extension
The Cloudflare SSL tools at https://github.com/cloudflare/cfssl might help. Here's what it shows for one of the example Snake Oil certs:

Private CA management
I've used this in the past and it worked great. https://github.com/cloudflare/cfssl
- Linux Certificate Authority root stores have a too simple view of 'trust'
- Creating an internal Certificate Authority in 2022 that is accepted by modern web browsers.

How to create users in Kubernetes
The first step is to create the source key that represents our user. This key is created using a tool like openssl but another popular tool to use is cfssl, created by Cloudflare. Some folks think cfssl is easier to use, and it definitely looks easier to script. But for this example we will use openssl. You can also choose to create the key using a number of different algorithms. For this example we will use ED25519.

[Legal notice] IoT Core will be discontinued on Aug. 16, 2023
TLS/SSL worked well with client certificates generated by the CFSSL API.

Feedback on a Self-signed SSL CA?
Not sure if relevant but we used tooling from CloudFlare in the past: https://github.com/cloudflare/cfssl

Nanos – A Unikernel
I can speak to this. Containers, and by extension k8s, break a well known security boundary that has existed for a very long time - whether you are using a real (hardware) server or a virtual machine on the cloud if you pop that instance/server generally speaking you only have access to that server. Yeh, you might find a db config with connection details if you landed on say a web app host but in general you still have to work to start popping the next N servers.
That's not the case when you are running in k8s and the last container breakout was just announced ~1 month ago: https://github.com/opencontainers/runc/security/advisories/G... .
At the end of the day it is simply not a security boundary. It can solve other problems but not security ones.
- Several container breakouts due to internally leaked fds
- Container breakout through process.cwd trickery and leaked fds

US Cybersecurity: The Urgent Need for Memory Safety in Software Products
It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C)
As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun) this year(https://cloud.redhat.com/blog/whats-new-in-red-hat-openshift...), which is written in C as an alternative to runc, which is written in Go(https://github.com/opencontainers/runc)...

Run Firefox on ChromeOS
Rabbit hole indeed. That wasn't related to my job at the time, lol. The job change came with a company-provided computer and that put an end to the tinkering.
BTW, I found my hacks to make runc run on Chromebook: https://github.com/opencontainers/runc/compare/main...gabrys...

Crun: Fast and lightweight OCI runtime and C library for running containers
being the main author of crun, I can clarify that statement: I am not a fan of Go _for this particular use case_.
Using C instead of Go avoided a bunch of the workarounds that exists in runc to workaround the Go runtime, e.g. https://github.com/opencontainers/runc/blob/main/libcontaine...

Bringing Memory Safety to sudo and su - with Ferrous Systems and Tweedegolf
Not OP, but if I had to guess, a lot of this can be picked up by just observing common security issues in the Linux space, since similar mistakes and oversights have caused quite a few real-world CVEs in the past, e.g. this random example of a TOCTTOU vulnerability in runc.
