13:40:10 ACTION-15 -- Robert Shilston to draft a non-normative document with Implementation Notes about how to load assets depending on MQs that can never become true (with help from Robin) -- due 2012-07-02 -- PENDINGREVIEW 13:40:10 http://www.w3.org/community/coremob/track/actions/15 13:40:11 Topic: Media Queries 13:40:55 Andrew_Betts: we have a blog post 13:41:00 ... which we published in response to this 13:41:15 http://labs.ft.com/2012/08/a-proposal-for-preloading-resources-bound-by-media-queries/ 13:41:36 http://lists.w3.org/Archives/Public/public-coremob/2012Aug/0040.html email about the FT Labs blog post 13:41:44 Andrew_Betts: the issue is more complex than darobin thought at the F2F 13:41:58 ... we can't assume that any MQ will never become true 13:42:11 ... we proved this with the device aspect ratio 13:42:28 ... but if you hook up a low res + high res display to a mac, the property does change 13:42:47 ... we can provide hints to the UA about things that are more likely to change 13:43:03 jfmoy: i was supposed to talk w/ darobin about that 13:43:12 ... this blog post came out first 13:43:29 ... i agree with Andrew_Betts 13:43:49 Andrew_Betts: in short, we've proposed the creation of a new css clause 13:43:53 ... media-preload-hint 13:44:06 ... taking a media query and specify a range of media queries that should be preloaded 13:44:12 ... it would be backwards compatible 13:44:18 ... but whether implementers would do it 13:44:27 Jo: it would take a lot to get it implemented 13:44:36 ... i posted a question to rob about this 13:44:42 ... isn't there a shortcut to this 13:44:56 ... display:none triggers loads (based on mobile-best-practices) 13:45:06 Andrew_Betts: that's effectively a hack 13:45:12 ... we're looking for something elegantly 13:45:33 +q 13:45:38 ... but yes, you can implement this today using that hack-workaround 13:45:42 s/+q/q+/G 13:45:51 ack tobie 13:46:00 tobie: Andrew_Betts / darobin's point is a good one 13:46:05 [In the past Opera did not load resources if the media queries that called for them were not true. They changed that for compatibility with deployed content, which relied on the resource being more-or-less instantly available] 13:46:10 ... there's value in bringing this request to the HTML WG 13:46:22 Josh_Soref: i'd say CSS 13:46:29 jfmoy: i'd say CSS 13:46:41 Jo: i think we're beyond our agreement here 13:46:55 s/agreement/remit/ 13:46:56 ... it's among things that are somewhat underspecified 13:47:05 ... like controlling order of loads 13:47:13 ... it's like a preemptive load 13:47:28 ... this is a question beyond the scope of what we're allowed to do 13:47:43 ... shouldn't we ask for clarification of meaning of display:none 13:47:56 ... if that's clarified and we ask for conformance to it 13:47:57 q+ 13:48:01 ... it seems like that's more in scope 13:48:05 q- 13:48:12 q+ 13:48:19 ack jf 13:48:23 q+ 13:48:28 jfmoy: i'd really like feedback from UAs 13:48:38 ... about that proposal 13:48:59 q+ 13:49:05 ack ch 13:49:05 ... i think this is something where a proposal to CSS WG would be helpful 13:49:15 chaals: i think we really need to talk to UA devs 13:49:25 ... it seems the requirement here is basically control of loading/preemptive loading 13:49:39 ... opera used to not to load non-required elements 13:49:46 ... it would then load on demand 13:49:54 ... it changed that behavior based on breaking the web 13:50:03 ... developers assumed things were preloaded 13:50:14 ... i think we should talk to both CSS + HTML, possibly also IETF:HTTP 13:50:26 q+ to ask about HTTP2 (push) 13:50:33 ack tobie 13:50:34 ... load control 13:50:49 tobie: i wanted to point out that our group is clearly not targeted at coming up with solutions for stuff 13:51:02 ... however identifying a problem and bringing it to existing groups is in scope 13:51:03 ack me 13:51:03 Josh_Soref, you wanted to ask about HTTP2 (push) 13:51:06 ack josh 13:51:25 SPDY 13:51:55 Josh: The SPDY protocol allows a website to push extra resources - maybe that is what we want... 13:51:58 q+ 13:52:05 … at least we should be looking at it. 13:52:10 ack And 13:52:11 Andrew_Betts: i think that is a partial solution 13:52:21 ... it doesn't provide the same solution that our solution would 13:52:31 ... it presupposes server side intelligence 13:52:42 ... whereas a media query allows intelligence to the UA 13:53:01 ... if the UA has highres/lowres, we want to preload the appropriate orientation-resolutions 13:53:17 Jo: we'll leave action-15 open 13:53:26 ... we'll need to take this forward on the list 13:55:00 ISSUE: We need to define our requirements for asset loading control (cf ACTION-15) 13:55:00 Created ISSUE-33 - We need to define our requirements for asset loading control (cf ACTION-15) ; please complete additional details at http://www.w3.org/community/coremob/track/issues/33/edit . 13:55:34 Jo: perhaps we can action Andrew_Betts to do this 13:55:58 ACTION: Betts to provoke discussion on list of ISSUE-33 13:55:59 Created ACTION-49 - Provoke discussion on list of ISSUE-33 [on Andrew Betts - due 2012-09-12]. 13:56:09 Topic: AOB 13:56:25 Jo: next meeting will be in London 13:56:34 ... do we want a call before we meet in London? 13:57:05 [+1 to call in 2 weeks] 13:57:50 NExt week? 13:57:53 Josh_Soref: three weeks = Yom Kippur = No 13:57:56 ACTION: Jo to figure out how to do a call between now and F2F 13:57:56 Created ACTION-50 - Figure out how to do a call between now and F2F [on Jo Rabin - due 2012-09-12]. 13:58:03 s/NE/Ne/ 13:58:26 Jo: would everyone please fill in the registration for the London F2F? 13:58:32 Jo: will you send out the agenda for F2F? 13:58:32 https://www.w3.org/2002/09/wbs/52857/CoremobF2FLondon20120802/ Registration for F2F 13:58:42 s/https:/-> https:/ 13:58:48 Jo: i will work on an agenda for the F2F 13:58:51 needs it for tavel approval 13:59:11 Jo: we might have a call for items for the agenda 13:59:29 ... further discussion on tobie 's document 13:59:45 ... and darobin's architecture document 13:59:49 any update on W3c test framework, status of matrics maker? 13:59:53 ... and testing 14:00:21 dan_ ask darobin 14:00:28 present+ 14:00:39 present+ tobie 14:00:52 present+ Tobie_Langel 14:01:01 Many thanks to Josh for scribing! 14:01:13 [thanks Josh (in perpetuity), Jo, all] 14:01:14 trackbot, eng meeting 14:01:14 Sorry, Josh_Soref, I don't understand 'trackbot, eng meeting'.
