asr-redact: Thai Speech PII Redaction

A pipeline that finds personally identifiable information in Thai speech and censors it in the audio itself, not just in the transcript. Silero VAD packs speech into ≤30 s windows so cuts land in silence, Typhoon ASR (a NeMo RNNT model, driven directly rather than through its convenience wrapper) returns subword timestamps, and two detectors (PyThaiNLP NER plus pattern rules for identifiers dictated digit by digit) mark the spans. Because an RNNT emits a token at or after the sound it describes, each token is widened back toward the previous emission so a redaction covers the whole word rather than its tail. Every input yields a beeped/silenced/noised copy and a JSON report of what was removed and when.

Message Bubble Generator

A dependency-free browser tool that animates a chat conversation on a chroma-key background and exports it as a WebM for video editing. Every bubble is drawn on a <canvas> at output resolution (nothing is a DOM element), so the recording is pixel-identical to the preview. Messages type themselves one grapheme at a time with the bubble growing to fit, and the stack eases upward as new bubbles arrive. Ships iMessage/LINE/Flat styles, 9:16 / 1:1 / 16:9 output, per-side colours, an alpha-channel mode, and a live mode for narrating a conversation while recording. Handles Thai wrapping and tone-mark clipping, which is why it exists: it produces the chat cutaways for RuffBlitz videos.

RuffBlitz School: Block-Based LMS

A learning management platform where courses are assembled from composable "blocks": Lego-like pieces (text, video, quizzes, code, and more) that instructors snap together to build lessons. Aimed at flexible, hands-on course authoring.

Research Philosophy

Reproducible

A result that only runs on the author's machine, on the author's split, is not a result.

Verified

Formal models where tests can't reach. Concurrent pipelines deadlock in states no unit test enumerates.

Measured

Baselines before models. Sometimes copying the last frame beats the network you spent a month training.

Deployed

The paper and the running system are the same project, finished at different times.

" A proof you can check and an experiment you can rerun:
the same discipline, applied twice.
