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.

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.

Create Production-Ready SDKs With gRPC Gateway
gRPC Gateway is a protoc plugin that reads gRPC service definitions and generates a reverse proxy server that translates a RESTful JSON API into gRPC.

To use more recent versions of protoc in future applications, you can download them from the Protobuf repository.

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).

What's involved in protobuf encoding?
Not much. You can check the source code in https://github.com/protocolbuffers/protobuf. For example, for serializing a boolean in C#: https://github.com/protocolbuffers/protobuf/blob/main/csharp/src/Google.Protobuf/WritingPrimitives.cs#L165. Strings and objects are a bit more complicated, but it is all about turning the data into its byte representation.

Trying To Solve The Confusion of Choice Between gRPC vs REST🕵
One of the key feature of gRPC is protobuf .proto file(nothing but just a contract for me between two communicator code components) This file and protobuff compiler is so mature, then it generates a direct client implementation using protoccompiler. ref

ProtoBuf message serialization in Akka.NET using protobuf-net
This article requires that reader is familar with core concept of Akka.NET serialization (see https://getakka.net/articles/serialization/serialization.html) and ProtoBuf-Net library (see https://github.com/protobuf-net/protobuf-net).

A .NET source generator for generating object mappings. Trimming save and fast. Inspired by MapStruct.
Not sure if it works with gRPC but I really like how Protobuf.NET uses attributes like other serializers instead of needing to write a .proto and generate (not-very-C#-friendly) classes from it. Well, until you need to interop with other languages.

Practice resources for handling and optimizing large game data sets?
I mentioned JSON, but there are many formats that are much more efficient. I can mention FlatBuffers, MessagePack and ProtoBuf. These are the ones I've used myself, and personally I'm most comfortable with MessagePack and ProtoBuf. I don't think the performance would be an issue if you had to choose between these three, it's mostly the API that is different.

Automatically generate proxy services for blazor wasm+asp.net core?
The closest way would be using Grpc.Web + Protobuf.net. The overall experience is pretty close to WCF server + Client where you share a common interface and let the client and server just call through those.

gRPC Development experience in modern .NET
Grpc Web with Blazor WASM is a really pleasant experience so far imo for my personal projects at home. You have strongly typed models and methods and you have choice on sharing the contract between client and server if you're using code first instead of proto IDL files (e.g. protobuf-net).

Integrating Apollo Studio with GraphQL for .NET - Part 2
It's pretty straight-forward to follow the protobuf-net docs to serialize the report, but we should really GZIP the stream for sending to reduce bandwidth consumption and improve performance:
-
Integrating Apollo Studio with GraphQL for .NET - Part 1
There are a number of Protobuf implementations for .NET Core, but I like protobuf-net as it's a nice, clean, Apache 2.0 Licensed implementation. It is also supported by protogen, a great online generator that will output protobuf-net classes ready for use (for its CSharp profile). If you open the latest schema from the link here, you can simply paste into the generator. NOTE: At the time of writing, [(js_preEncoded)=true] isn't supported by the generator, and can be removed from the proto schema.

Don't Use Protobuf for Telemetry
> Protobuf-java is a little heavy [...] Just depending on the library adds 1.6MB and nearly 700 classes before you even generate your own message classes.
By comparison, protobuf-net [1] is about 260KB and 68 classes. Python's [2] is a 1MB package download (with source).
Why's the Java one so big?
