Week 2 of KodeKloud: learned that not all Linux is Ubuntu (shocking).
Configured SELinux, set up passwordless SSH, created cron jobs, and battled a freezing UI.
Typed "apt" on CentOS about 5 times before my muscle memory caught up.
Full chaos:

4 days into the KodeKloud DevOps challenge.
Learned Linux user management, SSH security, and file permissions.
Also learned that running commands on the wrong host is a great way to waste 10 minutes.

🚨 New project: eBPF container escape detector!
What I learned:
- The kernel giveth and the kernel taketh away
- `unshare` is the devil's favorite syscall
- Debugging eBPF == staring at `dmesg` until 3AM
Peek the code carnage 👇

🛠️ Python CLI for AWS security audits
⏳ Spent 3hrs debugging missing directory (spoiler: mkdir fixes it)
Why build this?
🤯 Manual security checks don't scale
🐍 Wanted boto3 + pytest practice
📆 Needed cron-automated reports
Code's imperfect but functional: buff.ly/AbOkWnx
