11 March 2026, 8:00 pm - 5 minutes 10 secondsBig change brings big change (News)
This week’s been wild — Iran bombed AWS data centers to take down Claude, OpenAI dropped GPT-5.4 (and it’s seriously good for coding), and living brain cells are literally playing DOOM. We’ve also got a heartfelt take on what it feels like to be a 10x engineer in the age of AI, plus some cool new tools like Handy for speech-to-text and web haptics. Oh, and new MacBook Pros with M5 Pro and M5 Max are up for pre-order. Try not to impulse buy (or do).

2 March 2026, 9:00 pm - 1 hour 44 minutesOpus 4.5 changed everything (Interview)
Burke Holland works on GitHub Copilot by day and codes with his AI agents always. Early January, Burke posted about how Opus 4.5 changed everything. We were all still buzzing from the holiday-season 2x usage bump Claude gave us, and Opus 4.5 felt like a genuine step function in capability. Burke and I get into all the details. Opus 4.5 may have started the fire, but GPT-5.3 Codex is certainly living up to the hype.

Steve Ruiz joins us for a deep-dive on tldraw (a very good free whiteboard) and the business he’s built selling SDKs that help others build very good whiteboards (and more) with tldraw’s high-performance web canvas.
Along the way, we discuss the excitement/fear we share about keeping our agents busy, how SDK and infra companies are affected differently by agentic software than SaaS companies, how Steve is approaching the coming era of internal tooling, what will happen when we equip LLMs with an infinite canvas, and more.

Paul Dix joins us to discuss the InfluxDB co-founder’s journey adapting to an agentic world. Paul sent his AI coding agents on various real-world side quests and shares all his findings: what’s going to prod, what’s not, and why he’s (at least for a bit) back to coding by hand.
Update: He’s back to letting the AIs write code, but with a lot more oversight. For now…
