Similarly, I’d use Java when writing big, objective-oriented programs and wanted to make a cup of tea between the time I started the program and it was ready to run. A chef uses a paring knife when making small, delicate cuts, and I’d use Bash when writing small, portable scripts.
• Compile and run your programs faster than an interpreted language like Ruby; Write highly concurrent programs; Run directly on the underlying hardware; and Use modern features like packages (while excluding a lot of features I didn’t need, like classes).
• For their internal web APIs, the company may take advantage of technologies like protobuf for features that JSON/HTTP doesn’t provide—like type checking and versioning—but their public one will still be JSON/HTTP for accessibility. This is the same architecture I’ve used at my current and previous companies. At Segment we had a JSON/HTTP-based arch...
