Reliable, long-running, interactive agents in the cloud - something I've been working on. You can create durable agent sessions via the SDK, enqueue inputs, stream outputs. Agents grind away until they complete the goals you set. Agents in a workspace share a VFS.

It's crazy that Windows will post notifications for the most unsignificant stuff (like the unfamous "Windows Defender Antivirus did not find any threats"), but I had to check my event viewer for completely unrelated reasons to randomly discover that one of my HDDs is dying.

Vibe-migrated my blog as a holiday project: james.newtonking.com/archive/2026... 🎄

I made a console app to scrape HTML and output Markdown. It's 1500 lines of AI slop, one file, full of indecipherable regex. Basically a programming war crime ☠️ But it did its job and now I'll throw it away.

I enjoyed Stranger Things season 1, and am jumping back in to Season 5. Um…I don’t remember the acting being this bad before? And the sets? And the green screen? And this young man’s wig? Apparently I’ve missed a lot.

Why does this one kid look 50?

Aspire playground prototype

Aspire playground prototype

I'm curious, all of our @aspiredotdev users, is an #aspirePlayground something that you might use? I've been prototyping a bit, thinking about:

⬇️ Import existing AppHost/Docker compose file
⬆️ Export an AppHost.cs/SVG from the visual editor

What do you think? 🤓

Well crap. Turns out, MiniITX motherboards only have a single EPS connector for CPU power, which is actually limiting when running top-end consumer CPUs (9950X, etc.). Couldn't understand why my Cinebench scores were so low.

Time to sell some cases & motherboards & re-spec these builds 😔
