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.

Bear Does Analytics with CSS
The idea of using CSS-triggered requests for analytics was really cool to me when I first encountered it.
One guy on twitter (no longer available) used it for mouse tracking: overlay an invisible grid of squares on the page, each with a unique background image triggered on hover. Each background image sends a specific request to the server, which interprets it!
For fun one summer, I extended that idea to create a JS-free "css only async web chat": https://github.com/kkuchta/css-only-chat

No, CSS isn't a Programming Language
Isn't CSS Turing complete? Someone even implemented a chat client in it: https://github.com/kkuchta/css-only-chat

Gov.uk removed jquery and saw some performance improvements as a result
If it's something like a new reply to an issue raised, then you can either have it so these only show when the page reloads. Depending on how critical these notifications are, probably not the best solution. An alternative is to have a page that never stops loading. I've never actually used this approach, but I remember this guy used the approach for a JS-free chat system: https://github.com/kkuchta/css-only-chat

Yes, I can connect to a DB in CSS
Here's an actual CSS-only implementation of a chat app that I happened to stumble across yesterday while tinkering: https://github.com/kkuchta/css-only-chat

DSLs Are a Waste of Time
I hate yaml with a passion. It marginally better than xml for reading (wins huge on comment syntax) and worse for everything else. It makes zero sense we somehow ended up with it as standard configuration serialization format.
Note yaml is not a DSL. It's a tree serialization format! Everything interesting is happening after it is parsed. Extreme examples point to e.g. github actions conditions.
Anyway, back on topic - maybe not prolog for CDK, but still quite interesting: Dhall-kubernetes - https://github.com/dhall-lang/dhall-kubernetes

Why is Kubernetes adoption so hard?
At this point, if it’s painful enough, why isn’t compiling-to-yml tools more popular?
Example: https://github.com/dhall-lang/dhall-kubernetes
Haven’t used dhall myself but I’d definitely prefer a DSL on top of yaml.

The Dhall Configuration Language
Dhall is my favorite configuration language that I never get around to using.
I manage DNS in Terraform, and since every Terraform provider uses different objects definitions, and every object definition is rather verbose, Dhall would be a way to specify my own DRY types and leave the provider-specific details in one place. Adding new DNS entries and moving several domains between providers would be a matter of changing fewer lines.
Dhall also has Kubernetes bindings:
https://github.com/dhall-lang/dhall-kubernetes
Although I'm tempted to just stick to Helm here, even though it's less type-safe.

Why helm doesn't use a general purpose programming language for defining resources?
Not Helm directly, but does something like Dhall fit your question? https://github.com/dhall-lang/dhall-kubernetes

Dhall configuration language as another way to write manifests for Kubernetes
Have you heard about Dhall? It’s a programming language used for generating configuration files for a variety of purposes. One of them is to replace old and limited formats such as JSON and YAML. It is DRYable, secure, and even suitable for creating K8s manifests. The latter option isn’t something for anyone: you have to learn a new language and deal with its peculiarities, but it might be really helpful when you have tons of YAML configs. I’ve recently made a short intro to Dhall for K8s in this review.

Terraform 1.0 Release
Best thing is Dhall that I am aware of. Same situation, working as a consultant, forced to use broken things.

Write Gitlab CI Pipelines in Python Code
Lets look at a specific example. Take Kubernetes: everything is yaml, with complete schemas, all the way down. From your perspective this is configuration utopia, right? Meanwhile back in reality k8s is the poster child of "yaml hell". From the day it was released, people took one look at it, gave it a giant NOPE and instantly spawned half a dozen templating languages. The most popular of these is helm, which has a terrible, no good, very bad design: full of potential injection attacks from purely textual string substitution, manually specified indentation to embed parameterized blocks, virtually no intermediate validation, no way to validate unused features, etc etc
Compare to dhall which publishes a complete set of dhall-k8s schema mappings which enables you to factor out any design you want down to as few configuration variables as you like, while validating the configuration generators themselves at design time. https://github.com/dhall-lang/dhall-kubernetes#more-modular-...

INTERCAL, YAML, And Other Horrible Programming Languages
The solution I like is Dhall. They even have a Kubernetes solution that will catch a lot of issues at compile-time, before you try to apply it to Kubernetes. At earthly we aren't actually using it though. Our Kubernetes guru found it to be a bit slow but I am hopeful it or something like it will be the future.
What are some alternatives?
