SELinux AVC denied: stop guessing, start fixing

It happens more often than not. A web server gets installed, maybe a database, or perhaps a fresh Podman container. Settings are adjusted carefully, one by one. For testing, permissions shift to 777 — though never on live systems — yet somehow the error persists: Permission denied. There it is — buried in the logs. That overwhelming chunk of text from SELinux stares back: type=AVC msg=audit(16...

I built a tool that fixes Claude Code's most annoying problem — and here's what's coming next

If you use Claude Code seriously, you've hit this wall: You give Claude a complex task, switch to another window, come back 20 minutes later — and it's been completely frozen the entire time, silently waiting for your approval. No notification. No sound. No focus switch. Nothing. It kills your productivity. It kills Claude's momentum. And it happens constantly. So I built claude-alert. It hook...
