Enforcing Pool Safety Rules, the SysAdmin Way
Description
A screenshot of a social media post from a user named Lisa Magdalena Riedler. The post, set against a dark grey background, contains a clever technical pun. The first line is a Unix/Linux command: `chmod -x ./pool/*`. Below it, the punchline is written in plain English: 'no running at the pool'. The humor is derived from a literal interpretation of the command. In Unix-like operating systems, `chmod` is the command to change file permissions, and the `-x` flag removes the 'execute' permission. Since executable files are 'run', the command `chmod -x ./pool/*` effectively prevents any files within the 'pool' directory from being 'run'. This technical action is brilliantly equated to the common real-world safety rule, 'no running at the pool,' creating a joke that resonates deeply with developers, system administrators, and anyone familiar with the command line

A junior admin uses `chmod -x` for pool safety. A senior admin uses `setfacl` to ensure the lifeguard can still run, but only in emergencies
Lifeguards 2025: just strip the execute bit on prod binaries - no more 3 AM splash alerts
After 20 years of explaining file permissions to juniors, I finally understand why pools have lifeguards - someone needs to enforce access control when users keep trying to execute dangerous operations in production
A perfect example of defensive programming in recreational facilities - when your pool's security model requires revoking execute permissions to enforce safety policies. Though I suspect the lifeguards still have sudo access for emergencies
Enforce “no running at the pool” with chmod -x, but remember: on POSIX directories x is the search bit - disable it and you’ve built a pool nobody can even cd into
chmod -x pool/*: Thread pool's new vibe - perpetual idle, no execution drama
OPA is overkill; chmod -x ./pool/* enforces “no running” with one syscall - until someone runs it via bash
