Your Blink Questions Answered

Over the last day, we've collected hundreds of questions and votes from the developer community on Google Moderator (goo.gl/Uu0qV) that seek answers to your tough questions about Blink, Chromium's rendering engine.

+Paul Irish  sat down with Chrome's Web Platform PM +Alex Komoroske  and Blink engineering leads Darin Fisher and Eric Seidel to get some answers. 

The video (youtu.be/TlJob8K_OwE) is embedded below.

Below are all the top-voted questions, along with timecodes you can click:

1:12 What will be the relationship between the WebKit and Blink codebases going forward? 

2:42 When will Blink ship on the Chrome channels Canary/Beta/Stable?

3:25 How does the plan for transitioning the WebKit integrated in Android to Blink look like?

4:59 Can you elaborate on the idea of moving the DOM into JavaScript?
 
6:40 Can you elaborate on the idea of "removing obscure parts of the DOM and make backwards incompatible changesthat benefit performance or remove complexity"?

8:35 How will Blink responsibly deprecate prefixed CSS properties?

9:30 What will prevent the same collaborative development difficulties that have hampered Webkit emerging in Blink, as it gains more contributors and is ported to more platforms?

12:35 Will changes to Blink be contributed back to the WebKit project?

13:34 Google said problems living with the WebKit2 multi-process model was a prime reason to create Blink, but Apple engineers say they asked to integrate Chromium's multi-process into WebKit prior to creating WebKit2, and were refused. What gives?
 
16:46 Is the plan to shift Android's <webview> implementation over to Blink as well?

17:26 Will blink be able to support multiple scripting languages? E.g. Dart.

19:34 How will affect other browsers that have adopted WebKit?

20:44 Does this means Google stops contributions to WebKit?

21:31 What Open Source license will Blink have? Will it continue to support the H.264 video codec?
 
22:11 Any user-agent string changes? 

23:38 When we'll be able to test first versions of Blink in Chromium? 
 
24:15 How can developers follow Blink's development?

25:40 What is chromestatus.com about?
 
26:40 How will this impact Dart language's progress? 
 
27:13 Will this be a direct competitor against Mozilla's new engine? 

29:03 When will all existing vendor prefixes in Blink be phased out?

30:20 Will you support -blink-text-decoration: blink? ;)

The video is currently unavailable, apparently.
 
This all sounds very encouraging; I think you guys have made the right decision.
 
It's really nice that we get to see a video like this answering questions just one day after the announcement. 
 
One minor correction: Darin said that Chrome will use Blink on all platforms. Chrome on iOS will still use a UIWebView (which is based on Apple's WebKit) rather than Blink.
 
I have a question.

Does anyone have any idea when we will actually see a difference? I'm watching it, right now, and they said that they're using it right now and nobody knows because it's "about the same". Does anyone know when it will start to matter?
 
+Michael Goff That's very difficult to predict. The code starts off similar (the same really) as WebKit but over time some stuff will likely diverge. (This makes the case for standards-compliance critical as different browser engine implementations need to behave in a specified and expected manner.)

Your question seems to ask if there will be some kind of noticeable "big switch" and I would guess not. It's much more likely that there will incremental changes, many of which will be unseen. Over time, however, the hope is that this will bring significant improvements to Blink and, by extension, Chrome.
