Restarting Kubernetes deployments with Github Webhooks and Scala

blog.indoorvivants.com/2025-10-20-...

On my lazy Kubernetes cluster that hosts various apps I want to have the easiest possible way for automatic deployments - and reacting to Github package publishing seems just simple enough

But the good thing is that once it works (after trial and error) it continues to work in different environments, and you have a single file with a blueprint of what it takes to build the app on a clean machine.

Using a slightly more portable DSL than GH workflows

Probably the most horrific application of this approach is in sn-bindgen-web: github.com/indoorvivant...

Copying individual linux and llvm files, publishing 6 different forks into local cache, installing system AND vcpkg dependencies... It used to build NGINX Unit from source!

I use this old approach a lot in my apps (fullstack mostly) and I'm confident it's good enough for most people.

GitHub - keynmol/scala-native-interop-livecoding-lsug: Live coding session demonstrating approaches to interop with C, C++, Assembly from Scala 3 Native

Anton Sviridov @indoorvivants.com · Sep 22

To celebrate the release of Cats Effect for Native 0.5, I rebuilt my web interface for sn-bindgen in Smithy4s and Http4s.

Now on Native 0.5, and actually working!

LSUG July 2025 Scala Native Live Coding - Anton Sviridov

Anton Sviridov @indoorvivants.com · Aug 1

Here's a live coding session I did for London Scala User Group about Scala Native and how it can interop with C, C++, and even Assembly.

Super fun, by the end of it we had a blazing fast HTTP server built with a sprinkle of ARM64 assembly

It makes each platform infinitely more boring, thus reducing the desire to check it again and again in doom scrolling death spiral, but after gigabytes of rage bait and O-faced thumbnails I've given up.

It's probably the wrong thing to do, but after the horrors of For You page on Twitter I've sworn off any algorithmic timelines.

On Twitter I use addons.mozilla.org/en-GB/firefo..., on Bluesky I just don't open Discover, on Youtube I live on my Subscriptions page.

Download Control Panel for Twitter for Firefox. Gives you more control over Twitter and adds missing features and UI improvements

It was great fun to present at @londonscala.bsky.social , talking about modern CLI covenants as I see them, and using Scala Native to build a wonderfully personal snippet manager for myself

I respect you Noel but honestly, fuck licorice. Fuck it straight to hell.

I had fun contributing the new SimpleTable class to the ScalaSql query library. It lets you drop the `T[_]` from table definitions, and it's based on named tuples and structural types in Scala 3.7. Have a read.

I didn't know anything about Electron or any of its tooling prior to this, and the journey wasn't particularly smooth.

Electron bindings were really the only Scala-specific hurdle, the rest was JS tooling/Electron related.

Very satisfying to get something that finally works!

Got invited to Imperial College of London to do some livecoding for students, this time making a simple Electron app with Scala.js searching Scala libraries.

The shape of the library follows Langoustine, but here I also provide a simple jsonrpc implementation, which should work fine with virtual threads or just blocking APIs.

In the future I'd love to derive tool definitions from case classes.

For something more relatable, here's a Scaladex MCP server: github.com/keynmol/scal....

Note that the model did not get any project descriptions and decided to just wing it.

Anton Sviridov @indoorvivants.com · May 11

I've been playing around with MCP to understand the hype, and wrote a small library (codegen, really): github.com/indoorvivant...

This image itself was generated by my CLI (Scala Native btw!) tools, into which I added a mcp subcommand.
