I recently toyed with a tiny VM for protobuf, you can use it in redpanda WASM streams, or in streaming pipeline (without having to use SAX parsers or IDL shenanigans with projected message compiled...) for filtering and projecting before deserializing. 100% written by claude.

If only go had lambdas, functional interfaces and record classes...

I highly recommend anyone to read Google's [AIP](https://google.aip.dev/). There's even a grpc schema linter for it. Put more focus on the resource data design than nitpicking on transport details. I would consider the best lessons to be:

- Optional but supported user defined identifiers, it's so frustrating to work with API that passes you back an identifier.

- String identifier (names) for resources, with some kind of type namespacing, i.e. the prefix in the author's document - Consistent set of fields (create_time, update_time, annotations, ...)

- Avoid dynamic map (this is a JSON self-inflicted wound)

JSON parsing is a minefield, especially in cross-platforms scenarios (language and/or library). You won't encounter those problems on toy project or simple CRUD applications. For example, as soon as you deal with (u)int64 where values are greater than 2^53, a simple round-trip to javascript can wreak silent havoc.

See http://seriot.ch/projects/parsing_json.html

Protobuf support for google's first-class citizen languages is usually very good, i.e. C++, Java, Python and Go. For other languages, it depends on each implementation.

If the application is in go, you can likely embed litestream.

glibc already does dynamic dispatch for the memcpy family of functions.

There's a very high chance this is monetization of botnets, which adds even more to the overall shadyness.

Python is a portability minefield. I'll spend more time trying to get the script/package run than reading the bash script.
