Nuclear weapons are already scary enough, but when you dig deeper and find out how powerful the weapons truly are, they get even more terrifying. The weapons we’ve built after the first atomic bombs are so strong that you can basically use Hiroshima as a unit of measurement. The largest nuclear explosion in human history, the Tsar Bomba, detonated with a force of 50 megatons or the power of 3,333 Hiroshimas.
Google’s codebase — the programming instructions that run every one of its services from Gmail to Slides — span a whopping 2 billion lines of code that stretch across 1 billion files and require 86 terabytes of storage, according to Google engineering manager Rachel Potvin. She recently disclosed those figures at the @Scale engineering conference. She also noted that this massive collection of data is mirrored and continually updated in ten data centers peppered around the globe. “Not only is the size of the repository increasing,” Potvin explained during her lecture, “but the rate of change is also increasing. This is an exponential curve.”
