I’m interested in ocean container shipping, so I built a Google Sheets add-on to automate the process of tracking shipping containers. It’s called Container Tracker and I just got it live on the Google Marketplace. https://workspace.google.com/marketplace/app/container_track...

Main workload is done by the backend (serverless functions).

I am currently working on a HubSpot extension (that uses same backend) with the goal to target few other platforms where users work, and integrate the functionality into their daily workload, as opposed to having it as standalone website or mobile app. I have fun doing it.

Sounds fascinating, do you have any documentation on how you modify the yeast?

I really need to do a write-up. I kinda just whip up the easiest path and do it. For example for the grape, I needed to knock out some tryptophan synthesis genes so I could redirect the bioflux. Problem is that in bakers yeast they have a whole buncha copies of their chromosomes, so I had to knock out one of the genes and replace it with a different gene from grapes. Did that with a quick lil CRISPR switch. Had to el…

Starting from nothing, how much time (and money) might it take an individual to learn how to be able to do these things?

My meta side project for building other side projects: https://bodge.app/ I've always had a bunch of small side projects that I want to do that aren't worth the overhead required to actually put them together & keep them maintained. So, I built a small Lua-based FaaS platform to make each individual project less work whenever inspiration strikes. So far I've built: * A current-time API for some hacked-together IoT de…

This is great. One thing that is not immediately obvious to me is what kind of authentication it supports. Needing to authenticate the caller is the #1 piece of boilerplate that gets in the way of me completing mini-projects. It’s not hard, but it’s definitely a nonzero amount of effort. And this is coming from someone who has implemented many, many auth flows professionally.

It doesn't say because there's no special support for any auth protocols. Long-term I want to have out-of-the-box support for things like OAuth (for user-facing auth) or mutual TLS (for device/service auth). _Technically_ there's currently support for the cryptographic primitives required to do JWT (I added that because I wanted to support WebPush w/ payloads for myself), but those aren't documented because I intend to remove the current slightly-hacky custom APIs and replace them with some off the shelf libraries, but I'm still figuring out user-added libraries (and on top of that I'll also need to figure out support for native libraries).

Are there any auth protocols / flows you think would be important to support?

Developing a graph-based programming language called Graphoid. The original concept was to target AI-related programming. Probably not ready for that yet!

Repo: https://github.com/xvandervort/graphoid

Claude Code is doing the majority of the coding, with close supervision from me. I write notes while I'm working on it. Notes are here: https://www.patreon.com/cw/aiconfessions

Gymlocity (https://gymlocity.com) - All-in-one gym management platform for small gym owners.

Building this for personal trainers with home gyms and small 1-2 location owner-operated facilities. The big players (Mindbody, etc.) are overkill and expensive for this market.

Core features: class scheduling, member booking, Stripe payments, and workout programming (the part most gym software ignores - trainers still use spreadsheets or generic apps).

Stack: React 19 + Vite frontend, ASP.NET Core 10 API, PostgreSQL, multi-tenant architecture so each gym gets their own branded experience.

Currently polishing the member dashboard and workout tracking UI. The goal is something a solo trainer can set up in an afternoon without needing to call sales or sit through demos.

I'm working on Tech Posts (https://techposts.eu), a Hacker News for Europe!

Since the last time I posted on HN it's gained a decent amount of traffic and users. I'm particularly happy with the jobs section, which is growing into a high signal-noise source for European tech jobs: https://techposts.eu/jobs

The reason I started this website is because so much incredible innovation and growth in Europe flies under the radar. If you ask Americans many will say it's just "banks and museums", stagnant, or worse. But the reality is there is a huge spectrum of exciting companies starting and growing here. We have space launch companies, battery companies, AI companies, and a whole bunch of other interesting stuff. It's an exciting time to be a European in tech!

https://openrailwaymap.app OpenRailwayMap is a project focused on displaying everything railway related in the world, powered by OpenStreetMap data.

I love it! I used it last month to find a track that recently got noisy in our neighborhood and learned a lot about the regional rail network.
