This is defrag-0am. I no longer defragment hard drives at midnight, but I do try to defragment my thoughts.
I'm Yamauchi Katsuyoshi, a backend engineer, a Japan-registered Information Security Specialist (RISS), and a former Reserve Sergeant in the Japan Ground Self-Defense Force (JGSDF).
I work at Acompany. Most days it's servers, databases, and probably too much coffee.
Everything here is just my personal take.
If you find any brilliant ideas, that's thanks to me. If you spot any mistakes, they're mine too.
