Swift Talk 471 ThumbHash (Part 4) We apply our discrete cosine transform to an image, using Core Graphics to process the data, and see it working for the first time. talk.objc.io/episodes/S01...

Swift Talk 470 ThumbHash (Part 3) We extend our discrete cosine transform to work in two dimensions, so we can apply it to image data. Sorry about the audio this week! 😬 talk.objc.io/episodes/S01...

Swift Talk 469 ThumbHash (Part 2) We finish our basic version of a discrete cosine transform, and use it for some compression experiments. talk.objc.io/episodes/S01...

Swift Talk 468 ThumbHash (Part 1) In a new series, we reimplement the ThumbHash algorithm, starting with a simple discrete cosine transform. This episode is free to watch, enjoy! 😊 talk.objc.io/episodes/S01...

Swift Talk 467 Visual Node Editor (Part 9) We add share support, which exports diagrams as different content types, including text, JSON, image, and PDF. talk.objc.io/episodes/S01...

Swift Talk 466 Visual Node Editor (Part 8) We clean up the code and transform the project to a document-based app. talk.objc.io/episodes/S01...

Swift Talk 465 Visual Node Editor (Part 7) We add snapping to node resizing, with shared state managed in the model rather than in preferences or the environment. talk.objc.io/episodes/S01...
