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

Makes sense! I figured that may have been the case.

My default camera app is Leica LUX, but I’ve been curious about unprocessed photography and can’t stomach the cost for Halide.

Just installed :)

Built a parking garage occupancy tracker for my city (https://www.parkeergaragesdelft.nl/) after a city council decision on car-free city center policies got delayed due to missing data. The city only publishes real-time availability with no historical record, so I started logging it. The site now shows historical data plus analysis of weekly patterns. (Note: website is in Dutch, but the charts should be self-explanatory.)

Now working on a second tool that monitors public reports on illegal dumping, broken streetlights and more. It tracks how long the municipality takes to resolve them

Lately, I've developed an interest in local politics and started reading policy documents, following city council meetings and even lobbied for a local park. Presenting public data clearly can help shape opinions and keeps the city council accountable, especially important with the upcoming city council elections.

Building a 22-service e-commerce platform in Rust (Runs on ~300MB RAM)

I'm 17. For the past 6 months, I've been diving deep into Rust to answer a question for myself: "Is Rust actually viable for complex, enterprise-grade backend architectures, or is it just hype?"

To test this, I built a full distributed e-commerce system (22 microservices, gRPC, Event-Driven) using Axum and Tokio. This is not meant as “how everyone should build”, but as an exploration of trade-offs.

Some hard lessons I learned along the way: Complexity vs. Performance: … The "Memory Shock": … (idle baseline; load benchmarks still in progress) Over-engineering: …

I'm currently squashing the final bugs…

I'd love to hear from senior folks here: …

> Thank you. I have thrown printers out the literal window.

I have literally thrown one of those "winmodems" [1] out of the window back in the days. I then went out and drove with my car on it. I then put it in a bench vise until its PCB shattered to pieces. Utter destruction, much to the amusement of my brothers.

These were the days.

And big thanks to GP for his work of CUPS / Linux printing.

CentralCI (https://centralci.com) - Fully-managed Concourse CI as a service.

Got tired of helping enterprises run Concourse themselves, so we productized it. We've deployed and maintained Concourse for Starbucks, Accenture, Sky UK, and others over the years—CentralCI packages that operational knowledge into a SaaS.

Why Concourse over GitHub Actions?

* fly execute lets you test pipelines locally before pushing. No more "commit and pray" * fly intercept drops you into a running container to debug failures * Resource-based triggers can monitor anything—not just git pushes * Full pipeline visualization from dev to prod in one view * Workers you actually control (no arbitrary cache limits or runner queues)

What we handle:

* Dedicated Concourse instances on high-spec hardware (Ice Lake Xeon, DDR5, NVMe) * Worker scaling without the Kubernetes complexity * SOC compliance, auditing, AWS PrivateLink for enterprise * 24/7 support from people who've been running Concourse in production for years

The pitch is simple: Concourse is the right tool for complex CI/CD, but running it is a pain. We make it not a pain.
