Chirp Pong

Chirp Pong is a two-player paddle game where two phones pair and exchange the ball over sound, using each device's speaker and microphone instead of Wi-Fi or Bluetooth. The page offers a duel mode that pairs two phones through a chirp handshake and a practice mode against a CPU opponent, with selectable match lengths of 7, 11, or 15 points.

LaTeX renderer

2026-10-15T02:07:28+00:00

LaTeX renderer

LaTeX renderer turns LaTeX source into a rendered view, either a single display equation typeset by MathJax or a full document or prose fragment typeset by faster-latex, with a live preview beside the editor and a toolbar switch between Edit and Rendered views. Source can be typed, loaded from a URL or GitHub Gist, or picked from built-in examples, and the page keeps the LaTeX in the URL fragment so it can be shared as a readable or compressed link.

Tree Appreciator

Tree Appreciator

Tree Appreciator is a slow spot-the-difference game in which each round grows two 3D trees from one seed and asks the player to find a handful of small differences between them, such as a missing bough, a visiting bird, or an early-turning branch. Players tap a difference in either tree to notice it, can use limited hints and drag or zoom to view the trees from different angles, and earn appreciation points, leaves and herbarium entries for each pair completed.

Profiling web-edit with Python 3.15: flame graphs and source heatmaps

Profiling web-edit with Python 3.15: flame graphs and source heatmaps

Profiling the unmodified web-edit app with Python 3.15’s built-in `profiling.sampling` revealed that mixed line-ending preservation dominated a busy editing workload: `preserve_endings` appeared in 64.8% of 15,296 recorded CPU stacks, with `SequenceMatcher.find_longest_match` contributing 38.3% of leaf samples. Sampling all threads was essential, since 95.1% of stacks came from AnyIO’s worker thread and would have been missed by a main-thread-only profile.
