@sushantv94 Design and cost wise it is good but is the external body easily cleanable?
I have a coway purifier that has a pull out pre filter which is very convenient to clean.
Ever seen processes in state "Z" (zombie) in Linux? 🧟
They're not dangerous - they're just waiting to be buried.
What's a zombie?
A process that finished executing but whose parent hasn't read its exit status yet.
Why do they exist?
Linux keeps the process entry so the parent can call `wait()` and retrieve:
- Exit code
- Resource usage stats
- How it died (signal/normal exit)
Zombies use almost NO resources - just a tiny process table entry.
The problem?
If the parent never calls `wait()`, zombies pile up and waste PIDs!
The fix?
```bash
kill -SIGCHLD <parent_pid> # Remind parent to clean up
```
Or just kill the parent - init (PID 1) will adopt and reap them.
Proper parent processes always clean up their children. Be a good parent! 👨👧👦
@Gooner__14 DNS is like cell phone directory, you only remember the name of the person and not their phone number. So for a 5 years old, it is easier to call Mom/Dad instead of 10 digit phone number.
