The January 2026 Towards Data Science pieces I actually used: Ryan Pegoud cutting LLM memory 84% with Triton fused kernels, ACE context engineering, and Hugo Lu on the ceilings at Databricks and Snowflake.
RoPE rotates query and key vectors instead of adding an index, so the distance between two tokens stays the same wherever the sequence sits. Covers the rotation intuition, why dimension pairs rotate at different speeds, and a PyTorch implementation for a custom transformer.
The WordPress handbook now has a section on AI. Five rules cover who stays accountable, when you disclose model help, GPL compatibility, which contributions are in scope, and the quality bar reviewers can enforce.
Adding agents to a weak system mostly adds noise. Notes on DeepMind’s scaling paper: the 17.2x error amplification in uncoordinated swarms, where the four-agent plateau shows up, and the archetypes and centralized orchestrator I use instead.
Tammy Silva’s LinkedIn side project turned into 50 messages a day. She used an AI website builder to put up a WordPress hub in an afternoon, moved lead capture off DMs, and filled 10 coaching slots in two days. Includes the hook I use to route inbound leads.
Running more environments in parallel does not scale RL training, it just leaves the learner waiting. This post covers the actor-learner split, using Redis to move trajectories between them, and how V-trace corrects for stale off-policy data.
Siloed training data produces models that fail confidently. This walks through the Federated Learning Flower framework on a biased MNIST setup, the pyproject.toml config, and the jump from 65% to 96% accuracy.
About 60 lines of Python turn a laptop webcam into a pointing device. Uses OpenCV and MediaPipe Hands for the 21 hand landmarks, PyAutoGUI to move the cursor, and a smoothing buffer to kill the jitter.
Prompting an LLM for plugin and WooCommerce code ships fast, then leaves you debugging plumbing you never wrote. Where vibe coding falls apart in WordPress, and what the vetted version of the same function looks like.
Research PINNs are routinely tens to hundreds of times bigger than the problem needs. Burgers’ equation plateaus at about 150 parameters, and a hyperelasticity model I saw used 424x more than necessary. Start small and scale only when the physics loss will not converge.
