I've been experimenting a lot with **Claude Code and agentic coding workflows** recently.
One thing I kept running into is that Claude agents are actually pretty good at generating application logic, but the **backend layer is still messy**. Databases, auth, storage, deployments, and APIs us..."

However, Hidden State Poisoning Attacks (HiSPAs), a recently discovered vulnerability that corrupts SSM memory throu..."
"The model runs 100% locally in the browser with Transformers.js. Fun fact: I had to slow down frame capturing by 120ms because the model was too fast! Once I figure out a better UX so users can follow the generated captions more easily (less jumping), we can remove that delay. Suggestions welcome!

We introduce a feature-matching objective for language-model fine-tuning that targets sequen..."

"We're sharing ZeroProofML, a small framework for scientific ML problems where the target can be genuinely undefined or non-identifiable: poles, assay censoring boundaries, kinematic locks, etc. The underlying issue is division by zero. Not as a numerical bug, but as a semantic event that shows up wh..."

In this work, we instead view the outcome of pretraining as a distribution over parameter vectors, whose support already contains task-specific experts. We show that in sma..."
