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.

Apple releases Pkl – onfiguration as code language
> was utterly surprised how no one ever apparently has thought to create a configuration/templating system that's basically a fancy library on top of Scheme.
There's Clojure's extensible data notation: https://github.com/edn-format/edn

What Is Wrong with TOML?
EDN (Extensible Data Notation) is a subset of Clojure: https://github.com/edn-format/edn
It is:
- Streamable
- Extensible
- Whitespace-insensitive, but there are formatting conventions for readability

The real reason JSON has no comments
To begin with, EDN is somewhat like the JSON of Clojure. And regarding the code is data/data is code nature of Clojure, it is Clojure. It doesn't have some of the vagaries of JSON, and it is also extensible.

Ron: Rusty Object Notation
Alien is not a reason something is bad, just that's it's unusual. JSON was a bit alien when it first arrived as well, as everyone was used to XML at the time.
`{num 5, val 4}` looks fine to me, but we can do even better! We already know objects/maps are always in pairs, so we don't really need that comma either. Just do `{num 5 val 4}` and we save yet another unnecessary characters.
Of course, I didn't come up with this format myself, what I actually want JSON to be is EDN (https://github.com/edn-format/edn) which is a standalone format but also directly used in Clojure, so it already exists inside a programming language and works very well. There keys are strings though, so you example would end up being `{"num" 5 "val" 5 "person" var}`, where commas are optional.

JSON vs. XML with Douglas Crockford
I just checked out the spec, and it gets pretty ugly in the Table section. A lot of the json examples are both shorter and IMO more precise. Stuff that’s not allowed with [table] is allowed with [[table]], and it’s confusing to understand what level of depth I’m at.
I’ll take edn over any of “em. https://github.com/edn-format/edn

Taming the Time: how to install & develop with XTDB
As XT is written in Clojure and it natively supports Clojure’s data types, we were not satisfied with available JSON types and decided to give EDN a try - that way we would have way more supported types:

Hey Rustaceans! Got a question? Ask here! (14/2022)!
I've uploaded my WIP patch to https://github.com/cfredric/rlox/tree/8ef811e5d8c5c73cca652af33516499f627a03b1. (FYI /u/DroidLogician)
Thanks for investigating! You were right on the money: capture_upvalue calls new_upvalue which calls allocate_object, which may trigger GC. So if GC is triggered midway through constructing that uvs vector, part of the vector will be invalid. Rewriting the vector during the GC process fixed the crash.
