What comes next

You'll get one practical tutorial each week, usually Tuesday. Either a step-by-step you can copy-paste, a teardown of something I broke in production, or a CTF write-up with the defender's takeaway. No 10-things-you-should-know listicles, no curated link dumps.

Three posts to read first

• Harden a Linux VPS in 10 minutes — the long-form companion to your checklist
• Docker security: 2026 edition — what to fix first
• Self-host Vaultwarden in 12 minutes — your first useful self-host
