This behavior is not defined by the spec / left to the UA. At the moment, I don't believe either WebKit or Blink implementation will swap the image on (desktop) zoom.

They're complementary. <picture> uses subset of original srcset spec to meet the "resolution switching" use case - e.g. see Example 1 [1]. If you want to select an asset based on viewport width, then you'd either u

As far as the browser is concerned, there is no distinction between icon fonts or any other fonts. If your icon font fails to load within 3s then it'll go ahead and try to paint the page with a fallback -- the results of that will vary

We instrumented Chrome and measured the download times: approximately ~1.1% of font loads are longer than 3s. New timeout will help address that 1.1% by using a system fallback. http://www.igvita.com/2014/01/31&#x2

I don't know the details of your benchmark methodology or setup (server / client), so not sure I can offer a meaningful response... short of: let's not confuse "my benchmark failed" with "the future doesn'

Seems coincidental. Just highlights that we need HTTP/2, and the sooner the better... Inventing your own app-layer multiplexing on top of HTTP (via base64 chunks - ugh), is not an interesting problem to be solving in 2014.

We have a lot to learn on how to use server push effectively. That said, let's analyze some actual use case.. a) Page A currently inlines half dozen small assets on every page. These inlined resources inflate every page and are deliver

Short answer, yes. Longer answer, there are two ways QUIC can succeed: a) QUIC makes headway on its own, delivers significant perf win, moves to IETF and becomes a standalone protocol in the long run. b) TCP and TLS leverage techniques &amp

No need to buy anything, it's an MIT-licensed project, and a trivial implementation under the hood to boot. If I wasn't learning Go while writing it, I think it would take all of 5-10 minutes to replicate (including deploying to p

I think there is something else going on here. While it's plausible that different browsers may introduce some processing latency, we are definitely not talking about 100ms+ delays, or 30 to 8Mbit throughput drop. More likely.. try dis

AFAIK, no.. Maybe in private. If you're interested, checkout the Chromium source, there is a basic demo server checked in. Perhaps more importantly, we don't encourage people to at this point because it's a fast moving target

That's not a joke - it's true... The joke part of it is in: there are two types of systems at Google, the ones that are deprecated, and the ones that are not yet ready for production.
