As Python 2's demise draws near we reflect on Python's popularity, the growing adoption of static typing, and why the Python 3 transition took so long.

Plus Apple's audacious app store tactics, Google's troubles with Typescript, and more!

• Google feedback on TypeScript 3.5 — We know and expect every TypeScript upgrade to involve some work.

• Our journey to type checking 4 million lines of Python | Dropbox Tech Blog — Dropbox is a big user of Python. It’s our most widely used language both for backend services and the desktop client app (we are also heavy users of Go, TypeScript, and Rust). At our scale—millions of lines of Python—the dynamic typing in Python made code needlessly hard to understand and started to seriously impact productivity. T
