Tmux is Still Better Than Herdr (Here’s Why)
Sam Natale's 8-minute rebuttal (Aug 2026, 19k views) to the "ditch tmux for Herdr" wave: every feature people switch for (spin up a branch plus a fresh git worktree on the fly, a sidebar of agent status, a dashboard over agents and worktrees, automatic .env copying and node_modules symlinking) is shown working inside tmux with workmux.

Full Walkthrough: Workflow for AI Coding — Matt Pocock
Matt Pocock's 96-minute AI Engineer workshop (1.6M views): a complete idea-to-production workflow for AI coding, built on the thesis that 20-year-old software engineering fundamentals are what make agents work (Pragmatic Programmer, Fowler, Brooks, Ousterhout cited throughout; closing advice: "head to Amazon and just buy a ton of those old books").

Deep Dive into LLMs like ChatGPT
Karpathy's 3.5-hour general-audience deep dive (9.7M views, Feb 2025) covers the full ChatGPT pipeline: pretraining (internet → tokens → next-token prediction), supervised fine-tuning (conversations → an assistant persona), and reinforcement learning (practice problems → emergent reasoning). Throughout, he maps the stages onto how children learn from textbooks: exposition, worked examples, practice problems.

Apple Watch Ultra 4 In-Depth Review: As Good As the Hype?
The payoff to last week's two hands-on videos: DC Rainmaker's full in-depth Ultra 4 review after swim/bike/run/row/track testing against a Polar H10 chest strap, published the day before the watch ships. Bottom line on the sensor: "this new heart rate sensor is very accurate thus far in my testing", with excellent plots even in the hard cases (outdoor road cycling vibration, rowing hand motion). Cold weather, where optical HR actually struggles, hasn't been tested yet (he lives somewhere hot; Apple's own study sites were California and Malaysia).

How I Film Cinematic Cycling Videos With the DJI Osmo Action 6 (Settings + Workflow)
A one-camera challenge: Philip Carneiro films an entire 18-minute cycling video — riding footage, B-roll, and the talking-head sections — on nothing but a DJI Osmo Action 6, with the only exceptions being the shots where the camera or its accessories appear in frame (frame_0007 carries the on-screen title card "THIS VIDEO IS ENTIRELY SHOT ON THE DJI OSMO ACTION 6").

Apple Watch Ultra 4 & Series 12: BETTER HR, Steps & ECG! (All You Need To Know)
Series 12 ($399, frame_0013) and Ultra 4 ($799) share a redesigned optical + electrical heart-rate sensor on the new S11 chip: repositioned photodiodes, larger power-efficient green LEDs, improved ECG electrodes (frame_0005, frame_0009, frame_0011).

Apple Watch Ultra 4 Hands-On: 24 New Things Tech Deep-Dive
The Ultra 4 sibling to the same-day Series 12 hands-on, shot at Apple Park in the same session — and it explains the mechanism the Series 12 video left out: the LED array has been rearranged so the color diodes are now clustered by type (four green, four red, four infrared), which lets Apple drive 24/7 background readings off the green LEDs instead of the infrared ones. That's why background HR could go from every 5 minutes to every 5 seconds.

Apple Watch Series 12 Hands-on: What's Actually New?
DC Rainmaker's same-day hands-on from Apple Park: the Series 12 ($399, ships Sept 18) gets the S11 chip, a rebuilt optical HR package (24% larger rearranged ECG electrode area, eight windows with double photodiodes replacing four dots, a new LED array), a 60% stronger display, and new colors (dark bronze, gold, ceramic white/blue, Hermès) — "it's actually impressive how many more features there are than they showed in the keynote."

Herdr Crash Course — Step-by-Step Setup
Alejandro AO (AI educator, builds the Tau agent at Hugging Face) delivers a structured Herdr crash course: demo → what a multiplexer is → local + VPS setup → having an agent control Herdr itself. It's a second-chance conversion: "the first time I used Herdr... I didn't like it. Then I tried it again two weeks ago and I haven't been able to stop using it."

This Tmux "Rewrite" Is Actually Brilliant
DevOps Toolbox (Omer, a self-professed tmux power user with published tmux plugins) reviews Herdr (herdr.dev) — the Rust "tmux rewrite" agent-native terminal multiplexer — and, despite arriving maximally skeptical of "multiplexers for agents," mostly converts.
