Some things I've designed/built/launched/maintained professionally: web frontend/backends, realtime interactive graphics apps, data visualizations, computer vision apps, firmware, reverse engineering, video/image processing, apis, api integrations (payments/social/data), distributed systems, linux sysadmin, refactoring/maintaining legacy systems, managing small engineering teams, remote work, customer facing work.

Some areas of interest: the outdoors, health and fitness, art, music, environment, games, human computer interaction, product design, ui/ux, embedded/iot devices, privacy, security, networking, optimization, unusual companies/products, web, linux.

Looking for interesting software engineer or tech co-founder/director/advisor opportunities!

If you don't care about the built in games and just want to use it as a controller, at the lowest level you should be able to find various sensors inside the bike that you can to a raspberry pi for instance. If your bike has an app, you might be able to find some useful information in this article as well

I used this open source tool: https://github.com/ptx2/gymnasticon running on a raspberry pi with the ANT+ dongle. Took a little effort, but now on my Schwinn IC4 I can connect my bike to the peloton app and my Fenix 7 and get all the data at the same time.

Gymnasticon is another option. IME it works great for Zwift. Documentation claims it supports Rouvy, TrainerRoad, etc. The downside is the difficulty in finding any RPi right now. I was lucky enough to set mine up when it was easy to find an RPi Zero W for $10.

> I wish I was more of a hacker/programmer because I'd like to do some protocol sniffing and create a connector for Node-Red so that I could link the appliance to my home automation system without becoming a personal data asset for the manufacturer.

You may find this post (https://ptx2.net/posts/unbricking-a-bike-with-a-raspberry-pi...) inspirational.

This works well with pi. Connected with ant+ to my Garmin watch and get speed and cadence. Power gets calculated by Garmin. https://github.com/ptx2/gymnasticon

Apparently Schwinn iC4 can be used with the gymnasticon hack that uses the USB port with a Raspberry Pi. That seems to imply data does move through the USB port. I was hoping to skip the Raspeberry Pi and just use an ANT+ dongle, but I'm not familiar with what an ANT+ dongle is able to do.

I've been working for the last 3 years on an in-memory MVCC DB engine in C++, built from scratch. The engine incorporates several innovative design features. It has completely nonblocking transaction open and commit; incremental, concurrent, and nonblocking GC; and direct shared-memory access to data from client processes with zero-copy reads. All critical paths are lock-free and some are wait-free (e.g., transaction validation). Scalability is a work in progress but single-thread update throughput is ~5M TPS. I've also designed and partially implemented a high-level API over this database to expose transactional programming to C++ developers who would never normally use a database: https://senderista.github.io/atomik-website/.

Before starting this project, I worked on a distributed analytical database, supporting multiple scientific users:
