ProtobufProtobuf Tip #10: Choosing the right integer type
Protobuf has ten integer types. Use int64. In Go, even the slow cases decode a thousand integers in a few microseconds, so the choice almost never matters.

Buf CLI · ProtobufProtobuf now has full LSP support
Buf is proud to announce the first fully-featured, spec-compliant LSP server for Protobuf. The Language Server Protocol is the standard API for integrating language support into your favorite IDE or text editor, such as VSCode, IntelliJ, or Neovim. An LSP server provides the smarts that power go to definition, code completion, finding references, and semantics-aware syntax highlighting.

ProtobufProtovalidate is now v1.0
After two years of development, we're proud to announce that Protovalidate has reached v1.0. Protovalidate is the semantic validation library for Protobuf. Protobuf gives you the structure of your data, but Protovalidate ensures the quality of your data. Without semantic validation, you're stuck writing the same validation logic over and over again across every service that consumes your messages. With Protovalidate, you define your validation rules once, directly on your schemas, and they're enforced everywhere.

ProtobufIntroducing hyperpb: 10x faster dynamic Protobuf parsing that’s even 3x faster than generated code
Today we’re announcing public availability of hyperpb, a fully-dynamic Protobuf parser that is 10x faster than dynamicpb, the standard Go solution for dynamic Protobuf. In fact, it’s so efficient that it’s 3x faster than parsing with generated code! It also matches or beats vtprotobuf’s generated code at almost every benchmark, without skimping on correctness.
