It’s such a pleasure to be in the company of ⁦@martinfowler⁩’s Refactoring book again. Whenever you read it last, it’s time to read it again. And if you haven’t read it yet, please do before writing another line of code.

Based on absolute engagement — the platform doesn’t expose follower counts here, so large accounts score higher.

From likes, comments.

Why it worked

Opens with a short, self-contained line that is easy to take in at a glance.
Short enough to read in full without expanding, which removes a step before the point lands.
Short sentences keep the pace up, so the reader never has to re-read a line.

The mechanics

Hook: Plain observation
Structure: Hook → Landing
Style: Conversational paragraphs at a steady pace.
Tone: plain, matter-of-fact
Written for: Engineers and technical teams

Wow, seems like Google is buying Spirit Airlines' enterprise data for $10m (outbidding Mercor at $7.5m). Basically includes every internal document, email, workflow, and codebase for a once $6B company. Honestly, $10m for 34 years of operational data really seems like a steal.

Anthropic just pulled Claude Code from the Pro plan. Pro users wanting it need Max now. $100/month minimum. 5x jump. I'm on Max 20x so I'm fine. Flagging for anyone on Pro who's about to find out. No announcement. Just a pricing page edit.

major price cuts today: *80% drop for GPT-5.6 Luna, now $0.20 per million input tokens and $1.20 per million output *20% drop for GPT-5.6 Terra, to $2/$12 *GPT-5.6 Sol gets Fast mode in the API, up to 2.5x the speed for 2x the price, same intelligence

amazon's internal A.I. coding assistant decided the engineers' existing code was inadequate so the bot deleted it to start from scratch that resulted in taking down a part of AWS for 13 hours and was not the first time it had happened incredible t.co

I think @bot is another “Claude Code” moment for AI. I would estimate my personal AI usage is up something like 100x. And for everyone who reached out about how to build a “podcast summarizer” it took me about 15 seconds in Grok Bot and is better than what I had before.

For those confused why the US state and Silicon Valley are having a meltdown on twitter today. China released multiple AI models that are 50x more efficient than the best American AI models and made them open source, ruining the AI market

Fable one-shotted a Rust rewrite of the TerminalTextEffects Python library in 11M tokens. Startup time went from 87ms to 2ms and rendering speed is up by 9.6x. Now zero dependencies and a 3mb single exec 🤯 t.co

I just hoped back on Kimi K2.7 for some work yesterday. Hadn't been using it since GPT 5.6 and Fable. But great reminder of just how good these open-weight models have gotten. For what I was doing, Kimi was faster and just as good. Excited for K3!

The Omarchy 4 branch is now 30,000 lines of new code. The majority of it was written by GPT5.5. It's been so, so good at QML. You still need to review, but there's just no way this scale of a conversion would be feasible without AI in a reasonable time. t.co

I think it's great that all the model providers are coming out with their own CLIs, but let's be honest, no dev is going to want to have five different CLIs installed. They're going to want to learn and use one tool with all the models. For me, that tool is OpenCode.

I love the models Anthropic are offering, but I seriously hope it's a mistake that they're blocking alternative harness providers, like @opencode, from working with their subscriptions. Seems very customer hostile. t.co

Apple exodus set to continue. This is the price of keeping a bean counter at the head for so long. Cook's legacy will not improve by dragging his own departure out any longer. Maybe he should do like Ballmer and buy a basketball team?
