Ask HN: What Are You Working On? (June 2025)

After something like 15 years, I'm building again my pc from scratch. I'm learning a ton about those new technologies and how all the pieces fits together. It's a lot of fun.

a Finnish security engineer, a Swedish datacenter engineer, and myself built a self-hosted continuous deployment system that is built around a blue-green deployment strategy. (Inspired by AWS internal systems) we wanted a system that can integrate with any cloud service, VM provider, and/or bare metal.

We built this together at a previous organisation and moved all the internal and external services at that organisation to this system (It allowed the org to satisfy the ISO27001 requirements).

After being in operation for a couple of years, we have collected a lot of insights and feedback on what to change/improve for the open source version.

This summer I’m setting aside some time to work on making those changes for an open source version of what we call “Vanir”.

(Seems like good timing with the initiatives in EU to take back some ownership of the cloud stack).

No LLM or AI magic. Just simple state machines, extendable configuration, and a lovely GUI (web-based, no JavaScript).

The tech stack is python3, postgresql, ansible, and django.

I just took a fortnight off work with the intent of getting away from my laptop, but accidentally ended up making a listings site for London's independent / arts cinemas. As far as I can tell no such thing currently exists, and I feel like it should.

Obviously the main thing is getting the listings data, which as far as I know (mostly) isn't readily available any other way that scraping the cinemas' websites, for which I set this up as a separate-ish project[1]

I'm working on a neighbourhood analysis app. It gives people looking for a new apartment or travelling to a new city all the information they need at a glance. I ingested a lot of public info into a database and combined it with routing services to provide a simplified analysis of any spot. This includes local infrastructure and amenities, quality of public transport access, distances to the city center or your workplace, demographics and more. One thing I wanted to make sure is to keep everything local, since those API calls can get very expensive very quickly. I am learning a ton here.

I'm currently close to the public release. After that, I want to learn some ML techniques to predict Pieter Levels' Hoodmaps classifications from my publically sourced data. It would be cool to have accurate automatic predictions of the places-to-be for every city.
