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.

XL: An Extensible Programming Language
IMO, there’s a wide unexplored design space between the minimalism of Lisp and richness of other languages. A programming language inspired by something like KDL (https://github.com/kdl-org/kdl) has the potential to be in a very sweet spot between the two. "Everything is a node" instead of "everything is a list" is only slightly more complicated, but also vastly more readable that a soup of parenthesis.

The KDL Document Language
I'd love to understand why all the advertised implementations have permissive licenses except for the Rust implementation, which is released under the Parity Public License 7.0.0 [1]? This seems to be as restrictive as the GPL, no?
In my mind, copyleft licenses applied to infrastructural projects like kdl-rs prematurely limits their adoption and promotes the development of alternatives with more permissive licensing, since the spec is released under a Creative Commons license [2].

The KDL Document Language, an alternative to YAML/JSON/XML
p.s. if anyone is interested in helping or just wants the info, this is the tracking issue for implementations supporting 1.0 (the actual thing that just got released): https://github.com/kdl-org/kdl/issues/144

Hitting every branch on the way down
It's because they changed the versioning format: https://github.com/protocolbuffers/protobuf/releases?page=5
But I suppose old version still receive bugfixes.

Reverse Engineering Protobuf Definitions from Compiled Binaries
For at least 4 years protobuf has had decent support for self-describing messages (very similar to avro) as well as reflection
https://github.com/protocolbuffers/protobuf/blob/main/src/go...
Xgooglers trying to make do on the cheap will just create a Union of all their messages and include the message def in a self-describing message pattern. Super-sensitive network I/O can elide the message def (empty buffer) and any for RecordIO clone well file compression takes care of the definition.
Definitely useful to be able to dig out old defs but protobuf maintainers have surprisingly added useful features so you don’t have to.
Bonus points tho for extracting the protobuf defs that e.g. Apple bakes into their binaries.

Add extra stuff to a “standard” encoding? Sure, why not
> didn’t find any standard for separating protobuf messages
The fact that protobufs are not self-delimiting is an endless source of frustration, but I know of 2 standards:
- SerializeDelimited* is part of the protobuf library: https://github.com/protocolbuffers/protobuf/blob/main/src/go...
- Riegeli is "a file format for storing a sequence of string records, typically serialized protocol buffers. It supports dense compression, fast decoding, seeking, detection and optional skipping of data corruption, filtering of proto message fields for even faster decoding, and parallel encoding": https://github.com/google/riegeli

Block YouTube Ads on AppleTV by Decrypting and Stripping Ads from Profobuf
It looks like it is in fact universal. Just glancing at the code here, it looks like the tool searches any arbitrary file for bytes that look like encoded protobuf descriptors, specifically looking for bytes that are plausibly the beginning of a FileDescriptorProto message defined here:
https://github.com/protocolbuffers/protobuf/blob/main/src/go...
This takes advantage of the fact that such descriptors are commonly compiled into programs that use protobuf. The descriptors are usually embedded as constant byte arrays. That said, not all protobuf implementations embed the descriptors and those that do often have an option to inhibit such embedding (at the expense of losing some dynamic introspection features).
