Cat food dispenser under Jeedom via ESP8266

To avoid THE daily problem: 'feeding the hungry cat', I built a dispenser connected to Jeedom. This dispenser consists of a simple 12v motor actuated by a double relay and controlled by an ESP8266.

My Office Sits at 29 °C at Night, and the Sun Has Nothing to Do With It
|8 min read
Episode 5: six shutters deciding on their own, from their room temperature and the sun's track across their facade. The model was built from the land registry and thirty days of correlation. Its most useful output was telling me where not to act.

Episode 4: fifteen spoken announcements on a school day, from wake-up to bedtime. The sound played fine from day one, and nobody moved. Eight writing rules, a wake-up rewritten three times in one day, and what happens when the bedroom speaker is offline.

I Changed the Evening Schedule Three Times in One Week
|7 min read
Episode 3: the house now carries the shape of the day. Gate open at 7:55, television cut at 7:30 p.m., shutters closed at the same moment, and an official open dataset that suspends the whole thing during school holidays. Every piece took an evening, and that is what made changing my mind three times possible.

AI Didn't Automate My House. It Deleted the Cost of Trying.
|7 min read
Over a year of home automation run through an agent driving the Home Assistant API: 87 devices, nine ecosystems, 75 automations. What I got out of it is ideas I would never have tried, and diagnostics that cross five systems in one sitting.

Ten Years of Home Automation Alone. One Year With an Agent.

A survey of a ten-year home automation build: from Jeedom and hand-flashed ESP8266 boards to 87 devices across nine ecosystems. What I built alone, what arrived once I started working with an agent, and the two examples that carry the difference.

The Skill Was Real. The Seat Wasn't.
|11 min read
Product ownership, testing, security, platform engineering: most of what got hired as a separate seat over the last ten years is a skill that never needed one. On my team the fix landed on the tech lead, who now carries product judgment next to the technical expertise he already had. One field report, not a template — and it updates something I only got half right two posts ago.

Quality Isn't Read. It's Executed.
|10 min read
Yes, I trust the frontier models — I run them every day and I know what they produce. But calibrated confidence is still personal, not proof about the system. Here is the quality system I built on a regulated hospital ERP: what quality means when the software has to hold up in court, the 4 layers that enforce it, the ladder we measure it on, and what it still does not prove.

The Backlog Was Never the Job
|11 min read
The same week, my feed buried the Product Owner, saved the Product Manager, gave up reading AI code line by line, and handed a whole product to one person. Four posts, one event: scarcity changed sides. What dies is the relay function. What survives is product judgment — and it no longer belongs to a single role.

Doctrine Compounds. Models Don't.
|10 min read
Eight frontier models in six months, treated as what they have become: a versioned dependency that depreciates. What compounds is the doctrine — the ADRs agents read, the rules CI enforces, the versioned context. And a confession: our own inventory found the doctrine drifting — the part nothing executes had started to lie.

One More Prompt
|20 min read
Agentic AI removed the friction between an idea and running code — and the friction was the only brake I had. I build seven days a week; roughly 90% of what crosses my mind becomes a project. A first-person account of the hook: what behavioral science actually says, the sourced ADHD/hyperfocus detour, and the two questions that hurt — does any of it ship, and is it worth what it costs?

100% Agent-Written: Six Months on a Greenfield Rebuild
|18 min read
Eight frontier models in six months, most sold on self-verification. On Solstice, our greenfield platform, four months of development with redefined working methods turned model quality into velocity: roughly 4,500 commits, close to 1,000 PRs, 120-plus releases. What we automate in July — and what it took to get there.

When My Homelab Crashed: Migrating Proxmox's NVMe Without Losing Everything

The story of a homelab outage — LVM thin pool jammed at 97.8%, RAM thrashing into swap — and the migration of the Proxmox host onto an NVMe four times larger: a dd clone through a USB relay drive, zero reinstall, and the discard=on lesson learned the hard way.

AI Became a Team Reflex — From Meetings to Production

Six months into 2026, my team's workflow has quietly rewritten itself — and the job has never been this enjoyable. A panel of persona sub-agents reviews every PR and every issue. Meetings record themselves and turn into assigned GitHub/GitLab issues. The boring parts are gone. What's left is business, domain, product. The work we always wanted.

How a Trusted-LAN Checkbox Gave a Stranger Root in My Homelab
|12 min read
I run 40+ services behind Traefik. One of them — qBittorrent — trusted my LAN by default. So did my reverse proxy. The internet bypassed my auth, dropped a remote shell, and ran for days before I noticed. Here is what I found, what I changed, and why every homelab with a reverse proxy is one default checkbox away from the same fate.
