Service Workers

A service worker is a script that is run by your browser in the background, separate from a web page, opening the door to features which don't need a web page or user interaction. Rich offline experiences, periodic background syncs, push notifications— functionality that would normally require a native application—are coming to the web.

• SW are are just JS workers, so they can't access the DOM directly
• a SW can communicate w/ the pages it controls by responding to message sent via the postMessage interface
• SW is a programmable network proxy, allowing you to conrol how network requests from your page are handled
• it runs only when needed, and terminiates when unneeded (cannot rely on global state)
• service workers make extense use of promises

Monolithic repositories

1. full-stack dependencies & modifications in one place
2. independent deploys

We have a single large depot with almost all of Google's projects on it. This aids agile development and is much loved by our users, since it allows almost anyone to easily view almost any code, allows projects to share code, and allows engineers to move freely from project to project. Documentation and data is stored on the server as well as code.

Git Subtree

>Git subtree allows you to insert any repository as a sub-directory of another one. It is one of several ways Git projects can manage project dependencies.

Using Rebase to Remove Bad Commits

Rebase at your own risk!

Fixing up and squashing commits with rebase is great fun and handy to keep the logs clean from lots of little commits like typos, but only before a push (unless you're sure nobody else has pulled since then).

When you rebase, it re-writes all SHA values after the removed commit(s). This can be troublesome when you may have already pushed to a remote. This has serious implications for breaking the repository for collaborators.
