Barman vs pgBackRest: a decision tree for PostgreSQL backup in production

There's no universal winner. Barman wins on simplicity and real-time WAL streaming with low operational overhead. pgBackRest wins on volume and restore speed. The criteria matter more than the tool.

What Job Interviews Taught Me About Kubernetes

Kubernetes technical interviews have a problem nobody names: they ask about objects you'll never touch in production, while ignoring the mistakes that actually break real systems. Here's the map I was missing.

Docker Compose in Production in 2026: I Ran My Real Stack for 30 Days and Here Are the Numbers

A HN thread with 398 points blew up the debate again: is Docker Compose in production legitimate or an antipattern? I ran my real stack on Railway for 30 days and brought actual numbers. Spoiler: it's not embarrassing if you know exactly what it costs you.

Agents That Create Accounts, Buy Domains, and Deploy on Their Own: I Tested It Against My Real Stack — Here's What Broke (and What Worked)

The viral HN demo shows Cloudflare agents running the full infra cycle with zero human intervention. I replicated it against my Railway stack and documented exactly what the agent executed on its own, where I had to step in, and what permissions it asked for that it absolutely shouldn't have. Real a

macOS tar destroys files on Linux: I validated it in my real Railway pipeline and documented the 3 cases nobody mentions

A HN post about tar on macOS made the rounds again this week. The standard answer is "use GNU tar." I went further: I reproduced the 3 scenarios that actually break production in my Railway pipeline and documented the exact fix I use.

Barman Replacing pgbackrest: I Migrated My Postgres Backups in Production and Here's What I Found

pgbackrest went unmaintained. Barman shows up trending on HN almost immediately after. I did the actual migration on Railway, measured restore times, backup size, and configuration complexity. My conclusion is uncomfortable: the community is celebrating way too fast.

Canonical under DDoS: what my Railway logs and uptime say about my real exposure

The Canonical DDoS hit 178 points on HN and most devs read it as someone else's news. I read it as a mirror. I dug through my Railway logs, my Docker pipelines, and my Ubuntu dependencies — and what I found made me pretty uncomfortable.

Linux kernel vulnerabilities without distro notice: what this changes in my Ubuntu/Railway stack

Distros find out about kernel vulnerabilities at the same time as the public. I run on Railway over Ubuntu and this forced me to audit every layer of my stack. What I found isn't reassuring.

OpenAI on Amazon Bedrock: I simulated the migration from my current stack and the numbers don't add up like the announcement promises

The OpenAI on Amazon Bedrock announcement sounds promising. I simulated moving my real API calls to Bedrock and the cold start numbers, IAM overhead, and actual pricing destroy the value proposition for independent projects. The deal benefits AWS, not the dev.
