| project | what it is | stack |
|---|---|---|
| Arras (source) | photos live on your desktop as borderless widgets, each at its true aspect ratio. no cropping, no black bars. previously Photo Widget OSX, then Tableau | Swift, SwiftUI, AppKit, Core Animation |
| Fadeo | watches the frontmost app, the desktop you are on, whether you are in a meeting, then plays, fades or switches audio to match. every rule is yours, down to the second | Swift, SwiftUI, macOS audio |
| CodeForge | competitive programming platform on Codeforces data: custom contests, performance analytics, personalized recommendations, ICPC-style leaderboards | React, Node.js, MongoDB |
| OMR-Checker | hosted deployment of the open source OMRChecker engine, wrapped in a web UI and API, tuned for headless rendering | Python, OpenCV, NumPy |
PureMac is the studio name for the Mac apps. Both are open source and free to run:
brew install yashashwi-s/tap/arras yashashwi-s/tap/fadeo
Lathe asks two separate questions of every conversion job: did it produce a valid Typst document, and when it did, what did the rendered PDF preserve? Fidelity is a vector of content, layout, reading order, pagination and typography, with explicit abstentions instead of one collapsed score.
Multi-Agent-RL studies two-agent reinforcement games without shared states: value and policy iteration algorithms with convergence proofs to Nash equilibrium. RLbook is Sutton and Barto worked through example by example in Python.
