I'm trying to work on a new outdoor route building and mapping engine, focused on wilderness areas.

Super interested in this! I spend two or three days a week exploring the Rocky Mountains via mountain bike and backcountry skiing. I'm still not able to find a tool set that I love - my favorite still being CalTopo.

Any way to follow?

I'm working on re-writing Partizion to be faster, easier to use, simpler, and more beautiful (beautiful is good design — https://paulgraham.com/taste.html).

After the chrome MV3 migration which was an absolute rigmarole, I lost my taste for beauty. I want to get back to making beautiful software.

I'm working on Alumnium ( https://alumnium.ai ). It's an open-source library to simplify web application testing with Selenium/Playwright. I aim to create a stable and affordable tool that allows me to eliminate most of the support code I write for web tests (page objects, locators, etc.) and replace it with human-readable actions and assertions. These actions and assertions are then translated by an LLM into browser…

Pretty cool. I built my own framework to do something similar very recently. Microsoft omni parser and claude computer use alone can take you very far in testing almost anything.

I experimented with Computer Use and even though it's pretty cool, I ended up not using it for 2 main reasons:

1. It's unreasonably expensive. A single test "2+2=4" for a web calculator costs around $0.15. I run roughly 1k tests per month on CI and I don't want to spend $150 on those. The approach I took with Alumnium costs me $4 per month for the same amount of tests.

2. It tries too hard to make the test pass even when it's not possible. When I intentionally introduced bugs in applications, Computer Use sometimes pretended the everything was fine and marked the test passed. Alumnium on the other hand attempts to fail as early as possible.

I'm creating an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the…

That’s awesome! I’ve always wanted something similar like a Prezi presentation where you could navigate through different layers of the architecture down to the code.

I really like that idea!

Edit: It would be great if you could set the context and AI would generate it. It would make as an amazing addition to a standard Readme.

Further, at one level it could show endpoints and function signatures with parameters and how the argument usually looks as a value.

Which brings up another point, why doesn't Cursor or others allow me to say, "I'm in debug mode, show me if a value is dissimilar the values you normally get."
