* Continuing development on Breaka Club (https://breaka.club/blog/why-were-building-clubs-for-kids) — Turning kids from consumers into creators.
* GodotJS — https://github.com/godotjs/GodotJS — TypeScript for Godot
* Consulting for companies using GodotJS (and Unity).
With the recent work done enabling the use of Common Lisp in the browser on WASM, I've been thinking about spinning up a really simple static site that's just a CL REPL for people to play with.
My blog. I created it a couple years ago but didn't really know what to do with it. Have started to use it as a way to learn and have enjoyed writing more than I thought I would. Nothing crazy with UI and I am not talking about anything groundbreaking, but it's been fun!

I'm about to launch a new (now free) version of my Mac app, CurrentKey, which helps you keep track of workflows across macOS Spaces and track how you use your Mac. https://www.currentkey.com It had been a subscription app (4.5 stars) pulling in a few thousand per year, but I recently decided to try to broaden its appeal and make it free. The new version will launch within a day or two (the launch build is just "Waiting for Review" in App Store connect).
I'm working on a multi platform client for ATProto servers, like Bluesky. The emphasis is on a clean orthogonal UI, running on platforms the default client doesn't run on, and better use of screen space on small devices.
It's a work in progress, but it's at a stage where if you ask nicely I'll let you know where to download it.
There are a lot of apps that can be built on ATProto, the PDS, etc. If you are exploring the same space I'd especially like to hear from you. I'm easy to find, which is the most useful thing about being named Zigurd.
I am learning Unreal Engine for a year. im almost half way through and am making a simple Space Invaders clone which I will publish on steam for free.
This weekend I'm working on a new song for my NES game, Tactus. I've been busy setting up the business and preparing for its first outing at a convention, so it was nice to relax and just create for a bit.

Currently mostly happy with where this has ended up, but the percussion is a tad too basic and needs more work. One thing at a time I suppose. :)

Last week I spun up a HN clone for digital nomad news.
Since I was researching DNS and global mobility, and wanted to share links with others, figured I'd just spin up a link site (though I'm still the only user).
One unique difference is I have a field for English Title, since I consume a lot of Korean & Japanese articles and want to share these, but don't want to have people translate the titles before they understand why they should read them.
I've been working on LLMParty for some months. It is a collection of experiments that use LLM under the hood. For each experiment I tried to play with something different, such interaction, LLM knowledge, use, etc

I've spent several years solo-developing an ad-free website with over 50 different solitaire/puzzle games:
I've rewritten this project (almost) completely three times and now doing it for the fourth time, with tests and best practices.
I would be incredibly grateful for any feedback what I'm missing with it.
So far it has been great fun and I have learnt an incredible range of things!
https://postcrest.com It is a SaaS that allows you to create virtual characters to create, schedule and post educational or entertaining content on social media platforms with consistent personas. It is still very much work in progress, but already has some basic features working.
It allows anyone with ideas for engaging content to become a content creator without having to appear in front of the camera.
Still WithAudio https://desktop.with.audio . It's getting some attention and has actually sold licences!
Someone asked for a free license in exchange of detailed private review and bug reports. They have reported more than 10 bugs so far. I'm working on some of them right now.
WithAudio is a one time payment text to speech reader app. It's one time payment because it has no server and no recurring cost! A nice side effect of this is it's 100% private.
https://craftcx.com - Working on various aspects of trust and observability around the performance of AI Customer Support tooling. How's the support agent performing? Are the resolutions you're billed for "good" resolutions, or just deflecting the customer without helping?
Really difficult puzzle books that will only be available in dead tree format. Extreme killer sudoku, very hard wordsearches etc.
Was hoping to have these ready for Christmas season, but life as always gets in the way!
I am working on ZeroFS [0], a POSIX filesystem that works on top of S3.
I wanted to add the claude code changelog to my rss reader. It didn’t have a rss feed. Now it does. Had claude code built it: https://claude-code-changelog-rss.stevenmenke.workers.dev/fe...
Repo should work with any github hosted changelog file. https://github.com/stevenmenke/claude-code-changelog-rss
https://rounak.taptappers.club/fitness
I crunched Strava data (the Strava MCP project is incredible, and I ended up contributing to it!) and built myself this fitness hall of fame page (and also rejuvenated the remainder of the portfolio). Almost all of the stuff here is vibe coded, very happy how much I could achieve.
A open source Node.js lib that allows people to create and version control resumes using YAML.
Support LaTeX/PDF/Markdown outputs in one shot with professional typesetting. Support English/Chinese/Norwegian/French languages out of the box. With clang style, real time error reporting.
To release soon: HTML output.

please don't hug to death, I only got 10 GB of Data
it's 1st MVP and I got a dayjob, so please be kind. Haven't put out a howto yet, but ideally you have a notebook and a pen, some memories and grief to work through.
Mu - a personal app platform that includes chat with AI, news, video, posts and now mail. Solving a personal problem with ads, algorithms, tracking.
Tech is too addictive now. We need to get back to utility value. I'm trying to build an alternative with myself as user 1.

I'm still working on my Web Server Library .NET Core https://stratdev3.github.io/SimpleW/
I'm rewriting from scratch : https://github.com/stratdev3/SimpleW/releases/tag/REWRITE
I'm building a Typeform/Google Forms alternative that integrates into existing applications and stores data in your own database. It allows you to define forms in JSON Schema or JSON Forms. Forms can be added or removed dynamically, and submissions are sent to your backend and in turn stored in your database.
Built using our full-stack library toolkit Fragno [0].

Opensource Embedded Columnar Graph Database: https://github.com/LadybugDB/ladybug
Store your graphs in Parquet files on object storage or DuckDB files and query them using strongly typed Cypher. Advanced factorized join algorithms (details in a VLDB 2023 paper when it was called Kuzu).
Looking to serve externalized knowledge with small language models using this infra. Watch Andrej Karpathy's Cognitive Core podcasts more details.
I'm working on a way to make it super easy to create and share beautiful photo galleries that tell a story. Take your folders with photos and create a web gallery that works great on all devices.
The project has a CLI interface that is free and open-source, but you have to self-host the gallery. We are also building a SaaS app which is basically a managed version of the open-source tool with a visual builder and we take care of the hosting and CDN.

Egoless Engineering, a book about how to be an enabling staff engineer in the Nordic's largest mediahouse. I saved up vacation and took the whole of December off, mostly to relax. But I'm also working on more chapters for my book.
Simple meal tracker to give some macros but mainly give a health rating on 1-10 scale. http://meal-tracker.fly.dev
Slowly degoogling my life. Switched to FastMail a while ago, it works. Have written a simple shopping and todo list web app, and a minimal photo gallery. All very simple, mostly for one user only: Myself. Using these as excuses to learn about coding with LLMs. As I have retired a few years ago, I can afford the time, and work with no stress or deadlines. Also slowly improving my beer tracker system. All this as perl-based cgis under Apache, running on my home server/workstation.
Overly specific LLM research into KV cache eviction.
The vast majority of tokens in a sequence will be irrelevant to an attention mechanism outside of a very small window. Right now however we tend to either keep all cache values forever, or dump them all once they hit a certain age.
My theory is that you can train model to look at the key vectors and from that information alone work out how long to keep a the token in the cache for. Results so far look promising and it’s easy to add after the fact without retraining the core model itself.
I'm working on https://www.hessra.net/
It's a full identity and authorization platform targeted for service-to-service use cases. But my focus the last couple months has been to make provisioning identity super easy, and I think I've done that (at least compared to something like SPIRE).
So if anybody has CI/CD pipelines, AI agents, edge-functions, or multi-cloud workloads they want to give auditable identity, I can help!
Currently working on my own education by learning C from Antirez's C course on YouTube.
I've been working as an ERP developer for a couple years now and the job is so dull and boring that I'm already starting to feel stagnant. So, I am learning more advanced things now in order to: 1. Advance my career, and 2. Maybe code some linux tool (for personal use only, for now!) and stop looking at enterprise code.
I'm building a TypeScript to native code compiler, via the Dotnet CLR toolchain and Native AOT. This lets you use the excellent Dotnet std library - which in addition to being faster is also much safer than the npm ecosystem. There's also a node compat library, which exposes Node APIs but with CLR underneath.
The end result will be a binary (linux and mac for now) which you can run without NodeJS. Simple programs already work, and I have web apps very nearly running.
https://www.pocketpmo.com PocketPMO is meant for Founders, Project Managers and Project Manager Officers. It allows them to quickly size, cost, plan track and report on multiple projects. Teams can be added, Stakeholders managed, Risks Registered and Budgets tracked.
Currently working on the below open source project.
Ai-rganize — For using AI to sort files/folders on your local environment (Mac, Windows or Linux). (https://github.com/adefemi171/ai-rganize)
yaml2mcp — Got tired of writing MCP servers in JSON so I decided to build this as well. (https://github.com/adefemi171/yaml2mcp)
Working on updating my Your-Age-in-Days app[1] for iOS 26. The main motivation was to have the days I've lived always available on the lock screen with a more native feel than the workaround I had before (nightly Shortcut which updates the background image and adds the current number as an overlay to it).

I did (with the help of GPT) a simple script to deploy my Django+Celery projects to DigitalOcean. I was a bit afraid of that in the past, but now it's just a script that, after configuring a few variables (IP, etc), runs smoothly and gives me a perfectly deploy for a side project on a DO droplet. And also I can run again to just deploy a new version.
For most people this is silly but I am super happy that it works.
Open Source ERP system for Makerspaces and Community shared system.
Started out as a kanban style of system where anyone could request that we re-order cleaning supplies at a Makerspace. Has evolved to tagging assets and maintaining those assets and I'm working on adding ESP32 based device control to enable/disable devices through those QR codes.
https://tagbase.io … our mission is to stop counterfeits and empower brands. And as the CTO I have the privilege to play with all the nice technologies: Elixir both on the web and Raspberry Pis via the https://nerves-project.org. Having an IT background I love the challenges that come with hardware design and to learn new stuff because of that.
A music player for my 2 years old son. There are premade toys like Yoto player. But what is the fun in buying ready made?

Add some 3d printed enclosure and you are done. I am currently vibe coding a UI into it. I am planning to cram in adsp Bluetooth speaker support and some web config, maybe ota updates..
We’re building the Browserbase for mobile - Android & iOS at agentic scale with no concurrency limits.
We run them on bare metal without VM brittleness, fully GPU-accelerated with WebRTC streaming using hardware encoder. As good as it gets and it’s amazed every single person who tried it.
Still behind waitlist, give me a heads up at [email protected] to try it out.
I've been working on a personal project, from absolute zero to marketing, and it's been a great journey.
Mastering interviews and the most common questions, practicing all the questions to ace them, of course with AI and a lot of language chaining. Real time feedback, complete analysis of interview too. https://intermock.com
I am working on https://github.com/furkan/dockerlings, a TUI for learning docker (name and concept inspired by rustlings). It has attracted a surprising but welcome amount of interest, and I'm looking into extending it with more advanced exercise paths. Open to feedback & collaboration from all.
8th anniversary release of my app: Video Hub App - browse and organize your local video collection in style.
https://videohubapp.com/ & https://github.com/whyboris/Video-Hub-App (MIT open source)
Working on these:
https://github.com/Leo4815162342/dukascopy-node - a node.js tool for downloading free market price tick data
https://football-logos.cc/ - a curated directory of all football (soccer) logos in high-definition
I’ve been working on https://github.com/coro-sh/coro, which is an auth management platform for NATS.
The goal is basically to be a self hosted, open source alternative to Synadia Cloud’s BYON feature.
The whole project is shipped as a single Go binary with an embedded UI developed with Svelte. Has been a lot of fun to work on!

A 90-min workshop to introduce development Teams the full potential of AI coding agents.
Over the last few months I’ve been optimizing an AI-first SDLC for real engineering (not vibe code), getting amazing results on small Teams both in terms of delivery output and devex.
Some friends asked me to formally present and help their Teams, and enjoyed every moment of it.
I want to become a software professional, but I don't really know how I can do it. Focus on studying for many certificates or go to work or study at a higher level in school... Now AI is developing very fast; Claude can code very fast for every feature in my project, so I think I'm about to lose my job.
A browser automation Chrome extension and MCP. It consumes less context than playwright MCP and is more capable: it uses the playwright API directly, the Chrome extension is a CDP protocol proxy via WebSockets.
I use it for automating workflows in development but also filing taxes and other boring tasks
