250 stars (and counting) for TINA — A concurrency framework for Odin, with extensions for building web/infra software. Expect a few interesting changes in the next release. I'm also writing a few articles on Odin. I hope I can get them all done by the end of June. github.com/pmbanugo/tina

I don't think I ever got this speed when running just even way less test in JavaScript land. Takes between 1.x to 3.5 ms. Thank you Odin. It just needs a good web dev story to get Go and JS folks to consider it.

shows the output of running 144 odin test, all under 2 milliseconds.

After reading Posthog's blog about their recent issue and fix regarding their use of Tokio + Rayon, I decided to write about it. Unrelated to Rust, but a common problem I see with async/await as a primitive for concurrency. What do you think? pmbanugo.me/blog/why-asy...

The Tokio/Rayon Trap and Why Async/Await Fails Concurrency

Async/await makes concurrency easy to write, but incredibly complex to operate. Read on for why the Tokio/Rayon boundary is failing in production, and how explicit state machines fix it.

2 weeks after public release, Tina is gaining some eyeballs. if you haven't already, check it out — don't say I didn't tell you :) I'm currently working on adding a HTTP lib extension, and in the process decided I had to change some things at the core for better socket handling.

AI coding accelerates software pollution and further advances bad education on what it takes to make software Just as ppl expected the increase in software performance with 5 - 20x hardware performance decades ago. They’re doing a similar thing with AI - better hardware & models

In programming reliable software systems, first you make them correct and fault tolerant, then you make them fast.

Elimination is a core part of software optimisation. But it also carries over into other areas of life. If you can eliminate, thereby reducing the amount of task or functions you would like to do, you have enough memory space to juggle the vital few

I used the Die Hard water-jug puzzle to understand model checking, by building a naive solver. I only defined the rules; the strategy emerged from exploring every timeline/state. That’s why formal verification catches bugs tests miss. Part 1: pmbanugo.me/blog/tla-for...

Too many tools = information overload for AI agents (and devs). In my latest post, I explain why treating MCP/tools like a direct mapping of REST endpoints often backfires — and show a simpler approach that reduces eight similar endpoints into just two useful tools.

If you're looking for a networking library to use in Zig, you can try uSockets. It comes with an eventloop and other low level primitives for building networking apps. I published a package which makes it easy for you to integrate it in your @ziglang.bsky.social project github.com/pmbanugo/uSo...

I’m looking for the best way to send data between two threads in libuv? This isn’t using thread pool, so queue-work() wouldn’t be an option? It’s mostly one way communication and no shared data.

Peter Mbanugo @pmbanugo.me · 26/05/2025

Learn me some concurrency and event loop. Is this the piece to finally give me better understand of event loop at a basic level? Maybe try implementing something basic in @ziglang.bsky.social

a glimpe of a chapter in a book I picked up in order to learn event loop. it talks about how we can build concurrent servers without using threads

Most of this week has been finishing up technical article about Speculation Rules and finally getting to add it to my website. Yesterday was about tweaking my fetch server implementation using uWebSockets (mostly fixing the junk LLM added to it), which improved speed! Today's for Zig + libuv

After 48 hours, I finally get my @ziglang.bsky.social code, (which interacts with libuv) to compile. I'm going to take a long break before I run it to make sure it's working. Moments like the past 2 days make me question why I chose to try Zig. Perhaps just to to JS (or C#)

Quite an interesting need. Deno didn't click for me, but I was hoping it would have been a better alternative to Bun, b'cos I feel Bun doesn't yet know what to focus on. I was betting on Bun (it's fast in many places) but the stability in other areas is concerning. I've settled for Node (again)
