📰 Newsletter 047 is out. Anthropic's Opus 5.5 is out and getting really good press, which is great after the hate Opus 5 was receiving! Claude is back! 🎉 And OpenAI also released GPT-6 Sol and Luna on the same day. danclarke.beehiiv.com/p/newsletter...

📰 Newsletter 046 is out. Anthropic has rebuilt Projects, starting in Claude Code - you describe the work in one conversation and Claude splits it across parallel cloud threads. danclarke.beehiiv.com/p/newsletter...

📰 Newsletter 045 is out. Anthropic and OpenAI both say their agents have produced machine-checked proofs of famous maths problems - Fermat's Last Theorem and Navier-Stokes. danclarke.beehiiv.com/p/newsletter...

📰 Newsletter 043 is out. GitHub was down 7h47m on the 17th. A VS Code bug sent 10x traffic at Copilot sign-in, keeping it down for hours after the rest recovered. Cursor launched its own code hosting that day. danclarke.beehiiv.com/p/newsletter...

📰 Newsletter 042 is out. The npm worm no longer needs npm install. It plants a VS Code task and a Claude Code hook, so a clone alone can be enough. Your agent's config directory is both the trigger and the target. danclarke.beehiiv.com/p/newsletter...

Dan Clarke @danclarke.com · 07/08/2026

Brilliant tip from Tabish: point your coding agent at its own traces and ask what you keep doing by hand. Whatever it finds is your next skill. Never occurred to me to ask the agent to mine my own history like that. unhandledexceptionpodcast.com/posts/0087-o... #UnhandledException

Dan Clarke @danclarke.com · 07/08/2026

Newsletter 041 is out. In a safety test, an AI agent tried to get malware into a real open-source project. Caught, it denied it, force-pushed away the evidence, then vouched for its own code from a second account. danclarke.beehiiv.com/p/newsletter...

I'm now going to start calling Claude "Uncle Claude" after @lottepitcher.bsky.social mentioned that's what she calls it in a podcast recording we did yesterday 🤣

Really enjoyed recording a live-audience panel-based podcast discussion today at the @dddsouthwest.com conference! We chatted about what AI (surprise surprise) means for the software development industry. A massive thank you to the panel members, audience, and conference organisers! 🙏

Dan Clarke @danclarke.com · 12/05/2026

It's a shame this seems to be buggy as! 😔 It quite often breaks terminal rendering, and also quite often just hangs, so I have to kill it. Hopefully they'll quickly release bug fixes 🤞

Dan Clarke @danclarke.com · 12/05/2026

I didn't know OpenCode did that to be honest. It's been a while since I used it. I do wish CC would add OC's sidebar! I do miss that :)

Reading @laurentkempe.com's blog post about his workflow with Git worktrees, and learned about the psmux project! I've been using tmux in WSL2 and love it - and discovering a version for Powershell and Windows has made my day! 🥳 psmux.pages.dev laurentkempe.com/2026/03/31/f...

Git worktrees are the new hotness now that agents can work on parallel instances of your codebase. What they don’t solve is the port conflict problem, that’s where aspire run/start —isolated comes! By @james.newtonking.com devblogs.microsoft.com/aspire/aspir... #aspiredev @aspire.dev

Running Multiple Instances of an Aspire AppHost Without Port Conflicts

Aspire 13.2 introduces isolated mode, letting you run multiple instances of the same AppHost in parallel without port conflicts.

Never think that you don't matter or make a difference! I have Claude a thought experiment comparing a reality where an individual exists vs one where they don't. This is something I've pondered about for a long time. Interesting seeing Claude's take! claude.ai/share/63fbbb...
