I think it's fun but left some comments about tweaks needed IMO

| So the more of my code an AI does, the more I need a backend telling me — and it — what's actually happening. That's the opposite of what you'd assume. You'd think tools like Claude make analytics less necessary. For people like me, they make it _more_. | ||

I think maybe an interesting bit to fill out a bit more is that people usually think of analytics for a website or app they are releasing to other people, but it's also relevant if you're just building something for yourself because often times that data is not accessible.

One other things, is that it seems from the above section that you are going to use PostHog to debug your device and apps, but then you just use it for analytics of various kinds. Did you use it for debugging at all (logging, errors)?
I think either way, might need tweaking for consistency.

Basically, I expected the section below to be way different, about the debugging experience rather than analytics. Like MCP was used to build dashboards, but not so much to improve it?

| I'm not going to pretend I'm an engineer now. I do enough of that on LinkedIn. But the gap between "I have an idea" and "it's running on hardware on my desk" has collapsed, and it'll keep collapsing for people like me. It's genuinely exciting. | ||

| What hasn't changed is everything that happens after "it works." A thing that runs is not a thing you understand. The instrumentation is what lets me, and the AI I build with, keep something alive that neither of us could have written alone. |

Again, I don't quite get how PostHog helps you understand your app more. It gave you basic analytics about your choices, but that isn't really effecting the quality of your app as far as I read.

I've been vibe-coding a CO2 monitor and custom OS for a small device. You can blame @daniloc
This is a blog post about my experience vibe-coding, what modern coding looks like, and why for people like me analytics and MCPs are essential tools
