    Sure. But it would be a stretch to find any financial institution with as many as 360 million customer records. Maybe one of the state-owned commercial banks in China being the exc…

    I'm a few chapters into Silence on the Wire and enjoying it. Zalewski is brilliant. It's very theoretical however. I'd only recommend it if your motive for reading it is pure inter…
