iiinova — where your digital self keeps evolving

We've been working on the AEPs for a couple of years now, helping provide a standard for HTTP REST and gRPC APIs, and we've had conversations about pagination, filtering, error messages, and more. And we kept saying "these are great debates, wouldn't it be great if others could hear these too?"

Wondered how to use git work trees to have agents contribute PR's and push changes in parallel? Here's a quick guide! youtu.be/LoxnOzm1ctg?... #ai #agents #worktrees

totally! agreed. I think the "roles" that you provide in your toolkit is a bit farther than I'd like to go yet, although I have heard role-based LLMs tend to do better. Will check it out!

Congrats #aep-dev! a Terraform provider that can work with any aep-compliant API is pretty amazing! There was a lot of effort in getting Terraform right during my time at Google. I'm super excited that we're making steps toward that work becoming O(1) for well-designed, resource-oriented APIs.

The AEP project (especially this Terraform provider) feels like a culmination of a large portion of my career. As an industry, we spend so much effort trying to manually translate our APIs to the tools that users use. AEPs are proving that better-designed APIs lead to stronger tooling faster.

Is there really no atomic library / functionality in Python (e.g. for incrementing an integer?). Seems like requiring locks for this is a very expensive way of doing it. I guess asyncio's cooperative scheduling seems like the most robust solution. discuss.python.org/t/atomic-and.... #python

TIL that enums and boolean checking compile down to nearly identical assembly code in Rust: godbolt.org/z/bhKP8sMh1. I would have hoped so, but it's good that it's actually the case. So you can replace booleans with more semantic enums without fear! #rust #rustlang #compilers

// Type your code here, or load an example. pub enum Feature { Enabled, Disabled } // As of Rust 1.75, small functions are automatically // marked as `#[inline]` so they will not show up in ...

Anyone have a good example of a Go library that embeds a compiled library (C/Rust), and how to make that retrievable via `go get`? Trying to write a library in Rust, and re-use the logic in GoLang / Python via bindings. Python has a "wheels" concept to do this. #golang #go #bazel
