   Handwriter.ttf – Handwriting Synthesis with Harfbuzz WASM▲191

   During the hype of llama.ttf months ago, I was speculating the potential of WASM shaper for even crazier purpose, one that fitter to a font shaper's duty -- to synthesize font at runtime. This project as proof-of-concept implements a synthesizer that generates and rasterizes handwriting-style font, backed by a super-lightweight RNN model (~14MiB).

   Sketch – AI code-writing assistant that understands data content▲252

   Hey HN! I’m excited to share sketch: a tool to help anyone who uses python and pandas quickly iterate and get to answers for their data questions. Sketch installs as a pandas extension that offers utility functions that operate on natural language prompts. Using the `ask` interface you can get answers in natural language. Using the `howto` interface you can get get python and pandas code directly. The primary benefit of this over copilot and chatGPT is that this adds data-content based context so that the generated answers are much more accurate and relevant to the data problem at hand.…

    I built an interactive plotter art exhibit for SIGGRAPH▲167

    I'm enthralled with using pen plotters to make generative art. Last August at SIGGRAPH, I built an interactive experience for others to see how code can be used to make visual art. The linked blog post is my trials and tribulations of linking a MIDI controller to one of these algorithms and sending its output to a plotter, so that people may witness the end-to-end experience.
