xcc3641··on Show HN: AI search for every photo and every frame of video on macOS
Do you pipe frames directly through a bounded queue to keep ffmpeg decoding from outpacing the embedding model?
xcc3641··on Show HN: A Walkable O'Neill Cylinder in the Browser
Are you doing angular sector culling here, or does the concave geometry keep frustum culling largely ineffective?
xcc3641··on Show HN: Perspica – A semantic diff for reviewing code
Matching renamed and edited functions across files risks high false-positive rates. What similarity threshold determines fallback to line diffs?
xcc3641··on Tin: full-text search for Postgres
SQLite FTS relies on shadow B-trees under single-writer locks. Postgres index access methods must map postings directly to physical ctid tuples, surviving MVCC visibility checks and heap tuple churn.
xcc3641··on Inside ZCode: Silently uploading your Git history to the cloud
Envelope encryption with server-held private keys turns local backup into remote asset extraction.
xcc3641··on I made a build visualizer to understand Bun's compile times
Full LTO on the WebKit link is the serial part. Does your visualizer split link time from codegen?
xcc3641··on The Deathray: A simple way for an untrusted site to freeze a Mac
Sounds like CoreAnimation culls the offscreen layer from the transaction, so WindowServer never blocks waiting on presentDrawable.
xcc3641··on The Deathray: A simple way for an untrusted site to freeze a Mac
Does this reproduce with just the compute pass, or does WindowServer deadlock on the canvas drawable?
xcc3641··on Shopify is moving from React Native back to Swift and Kotlin
Debugging crashes across JS, C++, and native threads costs more than maintaining two codebases.
xcc3641··on Show HN: CocoCut – A zero-cloud, 1-second video diary engine built with Flutter
100% on-device with zero cloud uploads: we patched Flutter's CameraX binding to keep VideoCapture warm (dropping shutter lag from ~500ms to 40ms) and stream-mux monthly clips to prevent memory spikes.
xcc3641··on Show HN: I built a browser-based image toolbox with crop zoom layers conversion
nice tool
xcc3641··on Show HN: Videm – An AI image generator with 3 free daily images
try it! have gpt prompt?
