Running code: CPU time != wall time. Both matter, but which matters more varies on circumstances. Writing code in 2026: Human time != wall time. Ditto. (Brought to you by a morning in which I have spent more human time fighting CI than overseeing my bots.)
Go famously generates single static binaries you can scp and run. But the Go toolchain requires GOROOT, standard library, a dozen binaries. Wouldn't it be awesome if "download Go 1.28.0" meant download one binary called go1.28.0? (People who want editable GOROOT can run make.bash.)
A “sufficiently detailed spec” is the new “sufficiently advanced compiler”.
A rapidly increasing share of the software I use on a daily basis is bespoke. It makes bugs and papercuts in other software ever more exasperating. Once you've experienced mutable software there's no going back. I think blog.exe.dev/customizing-... may be most important thing ever on the exe blog.
Customizing Shelley, Customizing Software - exe.dev blog
With a coding agent living next to your software, customizing it is as easy as asking. Shelley even rebases your changes onto each upgrade.

I don’t care whether an agent wrote your code. But please please please write the readme yourself. At least the first part—the “what does it do and why do I care” part.
So far, agent orchestrators are like toothbrushes…I can use someone else’s, but I’d rather not.

Copy-on-write git worktrees
In the before times, I typically used a small, curated handful of git worktrees. Now the worktrees grow like bermuda grass, to the extent that they’ve become a disk space problem. Git worktrees do sha...

Having to RTFM for a tool I just built for myself is such a weird experience.
Rapid updates are a software supply chain threat vector. Use cooling off periods. Also, Mythos can go from vuln to working exploit in hours for trivial money and effort. Better patch fast. The call is coming from inside AND outside the house. This is fine.

Today's realization: I do very little direct editing of files any more. That means the main feature I care about is speed: get in, edit/read, get out. Switched from VSCode to Zed. Immediately and obviously better.
Chatting with the cashier, who just moved to Marin from rural Louisiana. His take: “Everyone here is super healthy, on the outside.“
![3-panel comic. (1) PERSON 1 behind podium on stage: We all hate springing forward. But we love falling back. (2) [Audience pictured listening] PERSON 1: Therefore, we are abolishing the *spring* time change *only*. We’ll gain an hour every year, but never lose one.
