I would be OK to publish the explainer as well - not sure what the process would be 14:36:48 FJH: we can do a fpwd of a note 14:37:13 ... there is respec magic for that 14:37:33 anssi: lots of discussions and implementations coming along 14:37:52 ... if we have to change our approach, we can shelve / update specs as needed 14:38:07 ... but given current state of implementation, pushing this forward would make sense 14:40:00 dom: my only concern was about the level of consensus on this particular approach; but a cfc is the perfect way to get this expressed :) 14:40:43 FJH: let's do a 2 weeks CfC on this then - for orientation sensor and the explainer 14:42:41 action: fjh to publish CfC for Orientation sensor and Motion Sensors Explainer 14:42:42 Created ACTION-789 - Publish cfc for orientation sensor and motion sensors explainer [on Frederick Hirsch - due 2017-04-13]. 14:43:09 Topic: Generic Sensor API 14:43:41 awaiting results of actions that Tobie is working on 14:43:45 Anssi: Tobie has something cooking for Issue 22 (permissions API integration) 14:43:57 ... it has implications to UI 14:44:39 Topic: Battery 14:44:58 Anssi: there were discussions around battery & fingerprinting, with a long ensuing discussion 14:45:03 https://github.com/w3c/battery/issues/10 14:45:09 ... we have identified a concrete spec improvement (see issue 10) 14:45:36 ... I'll update the spec soon; and the proposed update is already under implementation 14:46:44 dom: will then go back to CR 14:46:49 https://github.com/w3c/battery/issues/5#issuecomment-257617533 14:46:55 Dom: any feedback from Mozilla on this? 14:47:04 Anssi: they think it's a good idea but won't put the API back in 14:47:58 https://developer.microsoft.com/en-us/microsoft-edge/platform/status/batterystatusapi/?q=sort%3AVotes%20edge%3A%27Under%20Consideration%27 14:48:06 FJH: so the implementation question will still be up in our next CR 14:48:24 Anssi: battery is the 15th most requested feature for Edge too 14:50:31 s/15th/~30th/ 14:50:51 Topic: TPAC 14:51:01 Dom: should we meet there? it's Nov 6-10 in San Francisco 14:51:13 Anssi: I think it might be useful 14:51:19 FJH: it proved useful last year indeed 14:51:45 ... so another one would probably be useful 14:52:13 Anssi: yes, esp. with a meeting in the Silicon Valley 14:53:17 FJH: probably won't able to come myself 14:54:20 Dom: we need to answer the questionnaire before May 14 14:54:34 ... I won't be available Mon/Tue during TPAC due to WebRTC 14:55:22 Anssi: good to know - will probably align 2nd screen to that 14:55:36 FJH: so we should plan on Thu/Fri 14:56:28 ...
