Ask HN: What are you working on? (January 2026)

Is Rust a common choice in this space?

Still working on PocketWise (https://pocketwise.app), a simple double-entry accounting app. Just finished adding end-to-end encryption with a zero-trust server model. All encryption and decryption happens in the browser (using PRF), and the server only sees encrypted data.

Hey there!

For the past month I’ve been working on a creative / VFX / 3D tool that connects Apple devices into an all-in one node editor: https://subjectivedesigner.com/

With it, you can build interactive experiences, connect device sensors, compose shaders with AI models, orchestrate real-time data flows, and create projects that span across the entire Apple ecosystem. I’m posting about it regularly on social media and you can see some of it here: https://x.com/sxpstudio (Though it’s still early and most content is on socials thus far).

It’s done fully in SwiftUI + metal and also a good occasion to ramp up on agentic-powered software engineering. So far it’s been a lot of fun and working really great for me. And to be clear I’m absolutely not talking about vibe coding :-)

I've been experimenting with using LLMs for a content recommender system. Specifically I've built a news reader app that fetches news articles from multiple RSS feeds, uses an LLM to first deduplicate and then score them. The user can then rate the articles and those ratings are used as few-shot examples in the LLM scoring prompt. Any resulting low score articles (uninteresting to the user) are hidden by default and visible ones scaled by their score on a dynamic CSS grid like on a traditional newspaper front page. Looking good so far, but still testing and tweaking.

I was working on an Arazzo[0] generator as a plugin for the Serverless Framework. This has now become a fully fledged runner. So far I have it using multiple OpenAPI source descriptions, and just about got retry rules working. Next steps will be for it to be able to reference Workflows in external Arazzo documents.
