ETags: a pretty sweet feature of HTTP 1.1

HTTP caching review

HTTP provides two ways for servers to control client-side caching of page components:

• freshness may be based on a date or a token whose meaning is app-specific
• whether or not the client needs to confirm the cached version is up-to-date with the server

This breaks down as follows:

• Cache locally and don't check before using.

What's this about?

OS X 10.11, aka El Capitan, comes with a new system font for Chinese users, named PingFang, it includes 6 weights for both Simplified and Traditional Chinese. The same font also appear on iOS 9 as the default UI font, though Apple didn't mention it explicitly.

How to get it?

If you are in Apple Developer Program (costs 99 USD a year), then you can get them now at their developer resource site, otherwise you can wait for their public beta to come out in July or wait for the public release this fall (a free upgrade like previous release).

Or you can get PingFang.ttc from your developer friends, though you are probably violating its font license one way or another, but I am not a lawyer so freedom to you.
