Tools#

Polished, generally useful software. Each of these started as an experiment in proof-of-concept and graduated once it became a thing worth using rather than a thing worth demonstrating. Everything here runs in the browser unless noted.

Documents#

• mdshare (live). A split-pane markdown editor (LaTeX math, highlighted code, mermaid diagrams) where the document is compressed into the URL itself, so sharing is just copying the link; no server, nothing uploaded.

Meetings#

• commonroom (live). Serverless group video calls: pick a room name, share the link, and everyone in the room is connected over a full WebRTC mesh (up to 8 people), with room-wide shared settings. See also commonroom-recorder, which joins a call and records it for transcription.

Geometry and meshing#

• mesh-studio (live). Build CAD primitives or import STEP/IGES with OpenCASCADE.js, then inspect them in 3D, including each face's true NURBS surface (polynomials on faces), not just its triangulation.
• mesh-converter (live). Convert meshes between 19 formats (PLY, OBJ, STL, VTK, Gmsh, XDMF, …) with meshio running in-browser on Pyodide; inspect meshes in 3D and see what a lossy export would drop.

Numerical computing#

• numbl-figure-viewer (live). Open a figure exported from numbl and render it, with the underlying data included.
