iiinova — where your digital self keeps evolving

I’m writing a hands-on book series about concurrency, for anyone who wants to understand what happens behind async/await or coroutines. You’ll build a small concurrency runtime, step by step, and see how tasks pause, resume, and wait on each other. more info on the video and thread

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

Tina, Odin's concurrency framework with + a HTTP Server (Tina HTTP) just hit 140 stars on GitHub. Do with that what you may 😉

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.

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.

Instead of coloured functions or promise hell, you write Isolates (They don't block nor await). An Isolate receives a message, updates its state, and returns an Effect (Yield, Receive/Reply, IO, Crash) to the user-space scheduler.

demostrate the core unit of execution in Tina

100

Peter Mbanugo @pmbanugo.me · 14/04/2026

The architecture maps directly to the hardware constraint: 1. The Shard (Cell): 1 OS thread pinned to 1 CPU core. 2. The Isolates: lightweight processes representing a unit of concurrent execution. 3. The Grand Arena: A single memory block, partitioned at boot.

100

Peter Mbanugo @pmbanugo.me · 14/04/2026

I achieved this by strictly limiting what the programmer can do. Architecture constraint solves problems better than language features. So I chose these constraints: 🚫 No Garbage Collection. 🚫 No async/await. 🚫 No Mutexes. 🚫 No hidden allocations after boot.

shows the major things the framework rejected, and how it works around them.

Peter Mbanugo @pmbanugo.me · 14/04/2026

Software engineers usually have to compromise between speed and safety. You get the BEAM’s "let it crash" reliability, but pay with VM/GC overhead. Or you get C/Rust speed, but fight mutexes and async/await fragmentation. Tina was built to reject this compromise.

comparing Tina to Erlang/BEAM, Seastar, Tokio

Peter Mbanugo @pmbanugo.me · 14/04/2026

What happens when you combine Erlang-style concurrency + ScyllaDB's Seastar speed + deterministic simulation? Meet Tina: A strictly bounded, fault-tolerant, thread-per-core concurrency framework. 🧵👇

I've been experimenting with ZeroMQ for a couple of months and recently stumbled on NATS. Played around with it and implemented some parts of the core NATS protocol in @deno.land I'm making available only a few slots with 60% off only during Cyberweek. More info: protocol-zero.pmbanugo.me

What if Node.js EventEmitter worked across multiple processes and machines—with zero setup? I built Demitter, a lightweight distributed pub/sub system for Node.js. Think emitter.emit() and emitter.on()but distributed. 🚀 GitHub: dub.sh/zuxpUJT Demo 🎥: www.youtube.com/watch?v=LqQS... #javascript

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

Do you want to detect when code is executed with @deno.land @bun.sh or @nodejs.org ? You maybe have seen code like `typeof Deno != undefined`, but there's a better & cross-platform way to do it. The image shows an example, and I wrote more about it in this blog: pmbanugo.me/blog/runtime...

code snippet that show how to detect if code is running in Bun. It's not the best approach but it works

code snippet to show how to consistently detect the javascript runtime across platforms and systems. This is the better approach

Express.js works faster in Node.js, compared to Deno and Bun. So if you're migrating your Express/NestJS app to Bun/Deno, run your own benchmark and be sure you're not reducing your app's performance

It's great to talk to great builders like @darkweak.bsky.social and @alexjoelee.bsky.social. We'll talk about building your own CDN & CDN infrastructure ( @skip2networks.bsky.social), running Caddy server as part of CDN infrastructure, and self-hosting. Great to continue where we left of from 2024
