I am building a web application for learning math. I want it to be something between Khan Academy and Math Academy. Here is a demo of fourth grade https://demo.numerikos.com/ Currently the best part about it is one of my kids is using it. I have some more lessons ready, waiting to be released and I am currently working on Trigonometry.

I'm working on ghidra-delinker-extension [1], which is a relocatable object file exporter for Ghidra.

The algorithms needed to slice up a Ghidra database into relocatable sections, and especially to recover relocations through analysis are really tricky to get right. My MIPS analyzer in particular is an eldritch horror due to several factors combining into a huge mess (branch delay slots, split HI16/LO16 relocations, code flow analysis, register graph dependency...).

The entire endeavor requires an unusual level of exacting precision to work and will produce some really exotic undefined behavior when it fails, but when it works you feel like a mechanic in a Mad Max universe, stripping programs for parts and building unholy chimeras from them, some examples I've linked in the readme. It has also led to a poster presentation to the SURE workshop at ACM CCS 2025 in Taiwan as a hobbyist, an absolutely insane story.

Recently started working on my app for self-tracking again, a customizable combination of habit tracker, health journal and diary.

It should be as powerful as a spreadsheet for self-tracking, but the daily usability should be more on par with a habit tracker app.

The website and waiting list for anyone interested: https://dailyselftrack.com/

I'm going with my fourth (or fifth) attempt to create a digital twin of my apartment in a game engine.

This time it's in Godot and i want to add more interactive stuff in the virutal version, rather than just redraw the rooms with some lights synced with Home Assistant.

My friend and I are building Strandfall, a highly physical outdoor larp (live action role playing game) that uses custom spatial computers: https://strandfall.com

Players are survivors of a global disaster that has unleashed mysterious, deadly storms. For three hours, they investigate the origin of the storms and make fateful decisions about their future as individuals and as a community.

We received Immersive Arts funding, which means we can run it in Edinburgh later this year. Here's an excerpt from our 2025 grant application about exactly what those are:

--

Our “storm sensors” are novel spatial computers designed for outdoor usage over long distances. They will house ePaper displays, LoRa (long range) radios, accelerometers, gyroscopes, and GPS chips in a 3D-printed enclosure to provide a low-tech way to augment the reality of the park. These computers will be cheaper, more rugged, longer-lived, and more capable than smartphones, deployable to locations with zero cellular service and no battery charging options.

The sensors will be mounted on top of camera tripods for deployment. Runners will carry them through the park, then position and aim them in the correct direction, as co-ordinated by “operators” using walkie talkies. This will let players feel like they are really setting up important equipment, scanning historical sites for clues (like surveyors), and establishing laser communication links. Lacking colourful touchscreens, the sensors will be less distracting for runners, helping them focus on their surroundings. Essentially, they are a highly tactile and deeply realistic way of immersing players in a post-apocalyptic setting, since such devices – not smartphones – are the most likely to be used.

I'm scratching my own itch: building a yet another audio signal generator for smartphone. I need some extra functionality that is not available elsewhere, and impose some limitations "just because": it must be bare minimal PWA.

But actual app does not matter, the main take away for me is: it is easy and fast to write bloatware (esp. with AI), but not that easy to distill to what is really needed. And what looked like a weekend project, a couple of hours max (with help of AI), now lingers for 2+ weeks on-and-off on evenings (of manual effort).
