Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Design rules

⚠️ NOT FOR NAVIGATIONAL USE!
These are flash cards I made from study materials and nothing here is fit for navigational use.

Easy instructions to get QEMU/KVM and virt-manager up and running on Arch

Make sure your cpu support kvm with below command:

 grep -E "(vmx|svm)" --color=always /proc/cpuinfo

Make sure BIOS have enable “Virtualization Technology”.
User access to /dev/kvm so add your account into kvm(78) group:
