I keep 2,000+ machines across Slovenia, Croatia and Serbia answering in the morning.In between, I build small weird things and write down what I notice.

pookzie@eu:~$ check_visitor -H you --verbose
So this page runs one on you. The connection data comes from Cloudflare's trace on this domain, the rest is read by your own browser. Nothing about you is stored. Your network and rough location are looked up on this server. The only requests to someone else's server are for your weather, to Open-Meteo, with a location rounded to about 10 km.
JavaScript is off, so this page cannot run any checks. That is also the most private setting there is.
Waiting for the scan…
Any page can read these values with a few lines of JavaScript, without asking. Harmless one by one; together they form a fingerprint that can recognise your browser across sites, even after you clear cookies. Read locally here, never stored or sent. Hover or tap a group to see why it matters.
Sent in the User-Agent header with every request. Chromium browsers also hand out exact versions through client hints.
Memory is rounded and threads are capped in some browsers, but together with the OS they narrow down the device.
Screen size and pixel ratio are among the most identifying values a site can read.
The GPU model is readable through WebGL. Firefox and Safari generalise it; Chromium usually does not.
Input type tells a site whether you are on a phone, tablet or desktop, whatever the User-Agent claims.
Time zone and language list reveal roughly where you are, even behind a VPN.
Chromium shares rounded speed estimates so sites can adapt. Firefox and Safari do not share them.
Global Privacy Control is a legally recognised opt-out in some places, such as California. Do Not Track is retired and ignored.
A hash of the values above. A site that computes something similar can recognise this browser on later visits without any cookie.
pookzie@eu:~$ tail -f 404.log | ./classify --since=24h
This site is a handful of static files. Bots don't care: they knock on every door anyway, looking for WordPress logins, leaked .env files and unpatched servers. Every miss is written down by a small 404 handler. Here is what they tried. Updated every minute; no IP addresses are stored.

pookzie@eu:~$ fleet --status --simulate
System administrator and DevOps engineer on the Infrastructure team at DHH / Webtasy. 2,000+ hosts across Slovenia, Croatia and Serbia: shared hosting, VPSes, mail, DNS, firewalls and a private cloud. Most fixes end up in Puppet, so they survive the next reinstall. The map below is a simulation with made-up host names: what a day on the fleet looks like, not the fleet itself.
pookzie@eu:~/career$ git log --all --graph --since=2015
Eleven years, two kinds of machines. Pick a mission on the timeline or in the list.
Fix it once, then make sure Puppet fixes it forever.
Every run ends in a respawn. This one spawned me at DHH / Webtasy.
The useful part was the boring part: certificates that renew, names that resolve, boxes that still answer in the morning.
Junior title, production load. Where hosting stopped being a lab and became other people’s websites.
Different machines, same job: keep the process moving when something sticks.
One branch still waiting to be merged.
The stack I work in every day. CLI first, with a GUI fallback for the boxes that only have a GUI.
df before du. Always. Then du -x.
pookzie@eu:~$ ls ~/projects --live
The previews below are live widgets, not screenshots.
Audio messages with the real Earth–Mars light delay, computed from orbital elements in the browser.
River monitor for the Savinja: a bot scrapes ARSO, posts alerts to Telegram and feeds a live dashboard with webcams.
Heat your home, mine Bitcoin. A landing page for turning a space heater into something that pays back.
Three countesses of Celje: an empress, a woman drowned for marrying above her station, and a Serbian princess who outlived them all. A one-page history in English and Slovene, checked against Slovenska biografija.
Push-to-talk walkie-talkie app. Expo / React Native front end, Node backend, running on my own server.
