I am currently involved in two R&D projects:

- CyScout [1]: We’ve added support for the Solidity programming language in GitHub’s CodeQL. This enhancement engages the community to help identify security vulnerabilities in smart contracts on EVMs using a semantic code analysis engine.

- Roughchain [2][3]: A new blockchain focusing on solving the collusion problem [4][5], with participants who have a stake in the “real world” such as S&P 500 companies. The latest version of the whitepaper is available here https://docs.google.com/document/d/1L0Me9si4iMclOq8n-oG2yNQf...> , where comments are welcome. Currently, I am focused on a notes section addressing typical issues with L1 technologies, accessible here https://docs.google.com/document/d/1pV2Tcx_txCbfiPrNzcgKdOsE...>.

I’ve been working on a bespoke smartwatch for kids with Type 1 diabetes & their parents. The watch presents reliable CGM data and not much else, so the only distractions from the watch are important medical alerts. It has a novel haptic algorithm that taps at a frequency based on the current BG trend, the idea is the wearer can develop a sixth-sense of their BG without looking at the watch at all. The entire watch is custom-made from the PCB up. I have a small batch of prototypes assembled and my son has been wearing his at school. I have a few screenshots up at my product studio website: https://subtractive.computer

I’m considering how to take the watch to market as-is, or if I pivot the watch to be a fully open-source Pebble successor.

I've noticed that my son spends way too much time on YouTube or playing Minecraft and one of the few offline activities he enjoys doing on his own is coloring. And since he comes to me every time he wants a new coloring book and we spend about 10 minutes together searching for each picture, I made a website with a collection of coloring books for him. The site is very simple, but to be honest, I haven't had so much f…

The hands and feet on some of them are downright disturbing. I would not want my child coloring in AI generated slop, there's something fundamentally disconcerting about that.

Pretty sure no one will see this so: I'm working on a little game where you collect those really old T206 baseball cards and even worked out a system where you can send cards to people offline using a code system like Animal Crossing on the GC used

Still haven't come up with a fun way for the player to collect them though

For me the most important issue that needs to be solved right now is the increasing urban sprawl and the car dependent neighborhoods. It causes social isolation. Maintaining infrastructure like roads and electricity, is causing a strain on the economy for local municipalities. Not to mention the disastrous effect car based transportation has on the environment. I am a fullstack developer living in Norway. Last year I…

What is it about suburbs in particular that causes social isolation?

I'm working on scoping out specific problems facing "software as a medical device" (SaMD) companies. In particular issues around being able to release software at a reasonable cadence. I've been a CTO in this space for a couple of years and I am now consulting with other firms around the intersection of tech and regulatory.

It's a tight-rope walk of ensuring that all testing (software and non-software testing) and evidence is produced correctly and being able to release at a rapid pace to derisk each release. It's not uncommon for software to only be updated yearly, leading to very conservative changes and little iteration. Monthly releases are okay, but still not great.

I want to make it possible to release at least weekly and to do so safely.

If you work in this area, I'd love to chat and hear your experiences (email available via my website in bio).
