Conquering Kubernetes with Emacs

Specific Annoying workflow

Listing pods with kubectl get pods, then select a pod name and copy paste it into kubectl logs [pod name]

Why?

• I want to streamline my workflow and stop using the terminal
• learn more about kubernetes
• main kubernetes extension for Emacs out there is greedy for permissions

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
