I just blew Claude Code's mind.

At least, it's been over 6 minutes since I had an admittedly great idea & it's still "thinking".

I still remain highly skeptical of blanket trust in & applications of LLMs but I'm finding an intentionally configured Claude Code with Skills leads to a powerful brainstorming & planning system.

I haven't felt this generally creative in a long time & it's mostly due to "writing things down".

Last night I had a pretty vivid dream of playing the original Battlefield 1942. I remember when my friend showed me this game for the first time. I've never been so blown away by any video game experience as that day. It felt like anything in the environment could be manipulated and used.

State files drift, lock, and lie. Real-time simulation keeps infra accurate, collaborative, and safe to change. That’s @systeminit.com

State Files Are a Crime Scene
State files stall collaboration and punish refactoring. System Initiative fixes both with real-time simulation and change sets.

Most tools promise faster automation.
@systeminit.com promises something different: a new way to think about infrastructure.

Not just code. Not just pipelines.
A system that models reality, simulates change, and shifts how you approach every decision.

I’m fascinated how the concepts in Promise Theory (for me: autonomous agents & the idea that “all you can do is ask another, never command”) apply to complex systems, human interaction, societal cooperation, etc. Thank you, Mark!

In the last Oxide & Friends, @bcantrill.bsky.social argues in favor of dumb questions for getting real understanding, and I feel that one in my bones.

While I'm on the @oxide.computer cheer team, I'd highly recommend their Oxide and Friends podcast. The transparency and detail of the "epic bug hunt" episodes are a true gift to the software and technology community. 1/2

Another case where #rustlang is fast, which can lead to bugs. I forgot to handle this Tokio task cancellation, so the task got locked in a tight loop. Enough to pin CPU cores once deployed. Well *that* explains what happened! github.com/systeminit/s...

Sometimes I imagine someone from the past visiting 2025 and being amazed at our technology!

- Can't watch the game because the TV is doing a mandatory OS update
- Can't make a cup of coffee because the machine can't connect to wifi
- Can’t drive the car because the fob battery died

I'm kind sad that due to lack of prefs & clear navigation (that I can find), I'm up to 3 browser bookmarks for my primary work GitHub repo. Among those are open/non-draft prs reverse sorted (github.com/systeminit/s...) & active merge queue runs (github.com/systeminit/s...).
