Postgres LISTEN/NOTIFY Actually Scales (When You Treat It Like a Wake-Up, Not a Queue)

Postgres LISTEN/NOTIFY feels magical for low-latency streaming, but naïve “NOTIFY on every row” designs can bottleneck on an exclusive queue lock during commit. Treat notifications as wake-ups, batch them, and rely on the table as the durable source of truth (with periodic polling as a backstop) to scale safely.

Claude Opus 5: effort settings, verification loops, and why it feels more “agentic”

Claude Opus 5 (released July 24, 2026) is positioned as a more proactive, verification-focused Claude model with adjustable effort settings that trade thoroughness against token cost. It’s reported to perform strongly on coding and knowledge-work benchmarks while producing better interactive visual outputs.

FLUX 3 x Mimic: How Video-Action Models Teach Robots to Act

FLUX-mimic pairs Black Forest Labs’ FLUX 3 multimodal foundation model with mimic robotics to create a video-action model for general-purpose dexterous manipulation. The key idea: decode robot actions from the same learned world representation used for video prediction, keeping acting grounded in physical cause-and-effect.

FLUX 3 and the Rise of Multimodal Flow Models for Real-World Visual Intelligence

FLUX 3 is a multimodal foundation model trained to jointly learn from images, video, and audio in one unified architecture. By forcing consistency across senses, it aims to build a shared world representation—useful not only for generating coherent video/audio, but also for extending toward action prediction and physical AI.

Writing by Hand Trains Your Brain (and Your Hand): A Practical Guide

Handwriting can improve learning because it forces your brain to coordinate meaning with precise motor control. Research using high-density EEG reports different brain connectivity patterns for handwriting versus typewriting. This guide explains the practical pen-and-paper choices that make handwriting comfortable and effective.
