🗞️ nobody should type code by hand anymore. here's what's left. ghuntley.com/agency/

If you're curious how all those newfangled domain names come to be -- I wrote a feature for WIRED on top-level domains and the people who make them I thoroughly enjoyed meeting all the kind and fascinating people in this wacky domain world. (And I promise it has nothing to do with cat thongs.)
Soon, hundreds of new top-level domains, including .meow and .fart, could be added to the internet. WIRED goes inside the backroom shenanigans of ICANN, the organization at the helm.

Claude Opus 5.5 is out. “It's ~30% faster and ~40% cheaper than Opus 5 per task. In Claude Code: - 5-hour session limits increase 20% today - Opus 5.5 is priced lower, so it goes 25% further within limits - Pro, Max, and Team users get a reset to use anytime” www.anthropic.com/claude-opus-...
this is what my team has spent the last few months doing. the one thing in software engineering you never used to do is now the best thing you can be doing! the results are incredible - you can finally have the software you need to support all the features you want to ship!
... but also because this story continues a pattern of large-scale architectural changes that used to be dismissed as too risky or too expensive, that are getting done now that agents have changed the cost of writing and maintaining new code.

Replying to @dame.is
most people probably don't understand that agentic software development is now effectively the industry standard, even to the point that Zohran Mamdani's administration leverages agentic software development this is the reality we're working with, and it's a very tricky environment to navigate

finding I reach for skills less and less. anyone else the same? instead - I write code (😱) to instruct the sub/agent explicitly think @pi.dev extensions and swamp automations lsh.pckt.blog/skills-are-d...
does the same existential threat apply to internal platform teams too? if product teams are best placed to design tools to fit their use and can now build them to exact specifications, the generic solutions platform teams provide are no longer worth the hassle
the existential threat to companies building ai-based devtooling seems to be personal software devtooling appears to be heading towards bespoke software written by you/your org for you/your org build vs buy for devtools will settle to build if you need and can design it, your agent can build it

ooo this looks like a good rival to the GitHub Copliot app, which I’ve been using lately as the main driver of agents. the multiplayer aspect will be super cool to see how it feels let me in @zed.dev !
Today we’re introducing Delta. Delta is a multiplayer environment for coding with agents and reviewing what they build, powered by DeltaDB. The first invites to our private beta are going out now. zed.dev/blog/introducing-delta

this is great advice!
Would encourage you to stop inspecting a particular PR and let the agents continuously improve the code base as the feature/software comes together. If you are reviewing the PRs, identify the class of problem where it fails and improve the harness to produce better code next time.

The counterargument was that general models gracefully handle messy edge cases where smaller models fail. Other commenters pointed out that many repetitive tasks assigned to small models don't need AI at all — traditional deterministic code is still faster and cheaper. #programming 2/4
