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.

Cutting down AWS cost by $150k per year simply by shutting things off
> The best optimization is simply shutting things off
This is the way.
A similar idea has been bouncing around in my mind for a while now. An ideal, turnkey system would do the following:
- Execute via Lambda (serverless).
- Support automated startup and shutdown of various AWS resources on a schedule influenced by specially formatted tags.
- Enable resources to be brought back up out of schedule when demand dictates.
- Operate as a TCP/HTTP proxy that can delay clients so that a given service can be started when it is dormant or, even better, the service isn't serverless but you want it to be. This can't work for everything, but perhaps enough things such that the need to run always on services is reduced.
Cloud Custodian [1] can purportedly do some of this, but I've been reluctant to learn yet another YAML-based DSL to use it.
So this is my "make things designed to be always-on serverless instead" project and the work AWS has done to make Java apps function on Lambda keeps me thinking about the potential to take things that 1) have a relatively long startup time and 2) are designed to be long running service loops, and find a way to force them into the serverless execution model.

When have you screwed up, bad?
Goal was to clear up anything old and set us up to rotate keys in use. Why did I do it in the end of December? It was a quarterly goal and I learned to push those across the line if I wanted a good review. Great incentive, that one. I used Cloud Custodian for this. It has a terrible bug where the code says you'll be acting on days since the key was used but actually is reading days since it was created.

A Deep Dive Into Terraform Static Code Analysis Tools: Features and Comparisons
tfsec Owner/Maintainer: Aqua Security (acquired in 2021) Age: First released on GitHub on March 5th, 2019 License: MIT License tfsec project is no longer actively maintained in favor of the Trivy tool. But because many people still use it and it's quite famous, I added tfsec to this comparison. However, I recommend against using it for new projects.

My Cloud Resume Challenge Journey
Once I completed the main steps of the challenge, I went back to do some security modificaions including enabled DNSSEC, deploying WAF (I ended up removing this as the costs were quite high and instead set up account level throttling for my API) and running IAM Access Analyser to flag anything I'd over permissioned. I also set up Git commit signing and added a new Git Action workflow to run Tfsec any time I updated my terraform config files
