just learned about bikeshedding.
i do think we should be calling it something else though.

I told @mitchdennydev i wouldnt let him ship this if he didnt write a blog about it so pls read the blog so i am justified in my request
Did you know...💫Aspire gives you access to one of the most powerful terminal emulators on the planet, and it only takes one line of code to use your CLI apps in it?
Our very own @mitchdennydev wrote a deep dive on how you can attach a terminal emulator to any resource and interact with it right within the Aspire dashboard. Plus, in 13.6, you can even run REPLs against your containers and databases!

One more launch today: the new MCP Events spec is now supported in ChatGPT 🎉
MCP servers can now push real-time updates (messages, comments, status changes, whatever) to ChatGPT, triggering automations for your users 🤯
It’s easy to add to your MCP server, too! Just point Codex at the docs and let it rip:

me: how do i open pdf
claude: You're right to ask. The PDF is the prize; the mouse is the gate; and the map is the fulcrum that holds the raven's skull. The furniture's stale, but the instrument's fresh, and the fresh half is the half that counts. I deleted your home directory.

Published a few pareto rail levels built by gpt-6.1-sol . I suggest comparing them with gpt-6-astra - they feel close in quality and yet 6.1-sol is 80% cheaper. paretorail.com/match?model=g…

When we released SHENZHEN I/O 10 years ago, 2026 seemed far away. According to the in-game documents, though, the game is now set in the present!
Hope to see you at the Cool Dad concert!
(Thanks to Alex for pointing this out to us.)

Say what you will about Windows (OS), but the NT kernel really is an engineering marvel that still puts Linux to shame in many ways.
The quickest way to describe it for a programmer, is NT was more like an object-oriented language, with a strong security model from day one, whereas Linux is very…not.
A lot of the “good” features in Linux feel bolted-on (SELinux, Capabilities, Namespaces) because…well they were. I love to imagine an alternate history where NT won.
IMO, Microsoft *should* have made an “Open NT” in the early 2000s; not fully GPL-style open, but one where a large org could say…swap out a memory allocator for their own. (they sorta did this with limited source access, but it was too restrictive)
You could imagine say…an early Amazon forking OpenNT to create an “AmazonNT” for EC2, where they have a modified scheduler, network stack, whatever. But, the security+compatibility contract keeps a stable baseline on the Microsoft side.
Controversial take, but if we enter this era where users are giving AI agents increasingly higher levels of access control; the Linux kernel is legitimately a poor fit. Think about it; answer the question “What exactly is this AI agent allowed to do?”
On Standard Linux, it’s disgustingly messy with lots of overlap.
Do you use UIDs? GIDs? ACLs? CGROUPs? Policies? SELinux? Filesystem modes? There’s not a singular coherent graph of capabilities you can point to. Too many ways you can escape an initially narrow scope.
NT, by comparison, can go the route of explicitly typed resources, and then you could have these really strong centralized audit trails when an agent goes haywire…etc.
I know I’m rambling, but the point is…if you were greenfielding an OS kernel from scratch, in 2026, with the intent of being forward-looking, it would *not* look like Linux. Frankly, it’d probably look a lot closer to NT, or even a BSD fork…

I'll be speaking at @kc_dc next week -- reprising my "building a web framework from scratch" talk for the last time.
It's 1-hour of AI-free, slide-free, live-coding where I start with a HTTP server and build out the core components of an API framework in C#.
End of an era 🥲

The difference in taste between the models can be tricky to quantify. I decided to embrace the subjectivity and built Pareto Rail. Play game levels one-shot by Fable, GPT-5.6 Sol and others — then rank them blind for a personalized cost vs quality chart. paretorail.com
Glenn von Breadmeister retweeted
Pareto Rail is my benchmark for judging creative taste and I just pushed a Fable 5.1 level (more on the way later today). Give it a try now.

"You're right. I said that I ran the unit tests, but actually I ran a smoke test because the unit tests are still failing from an earlier change. You're right to call me out on that."

Hey Hermes - Replace your Google Home, Alexa, whatever you got with Hermes Agent on any device that can run the GUI or CLI locally!
Voice activation is now in Hermes Agent along with many other voice chat improvements.
To toggle listening for wake word on, just click the ear icon in the prompt box in your GUI, and you can activate Hermes voice chats with "Hey Hermes" - and it can even pick up profile names to activate voice chats with them!
Hermes Agent now has voice activation.
Say the wake word and Hermes opens a new session and listens for your command, hands-free in the CLI, TUI, or desktop app. Detection is local and off by default.

As interesting as "How it's Made" is, sometimes I really want to know more about how the stuff that makes the stuff actually works!
Like, who's the guy who thinks this up? Some autistic genius or a mechanical engineer? Or both?

If your WFH desk setup doesn't cost more than a used Honda Civic, you aren't serious about your pipeline.
My ergonomic chair is built from the salvaged suspension of a 2019 Tesla Model S.
My primary monitor is a converted IMAX screen I bought from a bankrupt theater in Oakland.
When I drag a cell in Google Sheets, I physically have to rotate my entire torso. I burn 400 active calories a day just searching for the Slack icon.
Stop complaining about back pain and optimize your environment.
