Hi, I’m Jonne 👋

This site covers three things I care about: practical sysadmin work, helping aging parents with technology, and simple learning games for kids. That’s a weird combination — but it’s what I do, so here we are.

🛠️ For Sysadmins

The posts I’d hand to a new junior admin on day one.

The fundamentals

• Setting Up a Home Lab: A Beginner’s Guide — what to buy, what to install, what to skip. The post I wish I’d had at 22.
• The 5-Minute Server Health Check That Could Save Your Career — the 5-minute check that catches 80% of problems before they page you.
• The Art of Reading Logs Like a Detective — stop drowning in logs. Start at the end. Filter ruthlessly.
• The Friday Backup Audit: Because Hope Is Not a Strategy — the 20-minute weekly ritual that prevents Monday-morning disasters.

Level up

• Why Your Monitoring is Broken — most monitoring is alert noise. Here’s how to fix it.
• Zero Trust for Small Teams — practical steps for teams too small for a “Zero Trust Initiative”.
• Kubernetes Without Jargon — pods are processes, services are stable names. That’s it.
• Stop Doing Things Manually: 5 Scripts — five copy-paste scripts (PowerShell + Bash) that handle the boring 5-minute tasks.

Career & real talk

• I Was the Only IT Person for 3 Years — the documentation I wish I’d written. Includes a template.
• What IT Pros Actually Do On Their Own Machines — the honest version.
• The Mistakes I Made (And Why They Led Me to Build My Own Password Manager) — my graveyard of mistakes, so you can avoid them.
