Zakim to WebEx change

<fjh> Discuss change to WebEx and timing

<fjh> https://lists.w3.org/Archives/Public/public-device-apis/2015May/0037.html

<fjh> will use webex for voice only, not chat or screen sharing, will send info, plan to use it instead of zakim for next call

Web Payments Use Cases

<fjh> Request for review before June 16: https://lists.w3.org/Archives/Public/public-device-apis/2015Apr/0038.html

<Claes> Would it be ok to take the topic "TCP/UDP Socket API to Community Group" now?

TCP/UDP Socket API to Community Group

<fjh> https://lists.w3.org/Archives/Public/public-device-apis/2015Apr/0000.html and https://lists.w3.org/Archives/Public/public-device-apis/2015Apr/0022.html

from http://www.w3.org/2011/07/DeviceAPICharter: "... based on the current Web browser security model"

<fjh> I’ve reviewed this and the community group seems like a good approach for now, if the situation changes we can consider moving this into DAP if it makes sense

Ambient Light

<fjh> Anssi msg to Microsoft team https://lists.w3.org/Archives/Public/public-device-apis/2015Apr/0028.html

<fjh> Adrian acknowledged

Generic Sensor API

<fjh> issues: https://github.com/w3c/sensors/

tobie: I was expecting people to contribute via GH issues
... I'm happy to go through the high level bits
... can work on a FPWD too
... we started working on the GH repo around Nov 2014
... a lot of activity within a week or so
... the high level goals
... has been working with Rick Waldron who contributed the initial spec blueprint
... that can be applied to specific sensors being worked on in this group
... issues: understand performance issues, how much the browser is aware of existing sensors
... would like to talk to implementers with regard the issues around performance in particular

<fjh> anssik: should connect you with our browser people that work on chromium

<fjh> anssik: you need to reach out to Google

<fjh> anssik: Tim Volodine has implemented device orientation, motion

<fjh> anssik: also Mounir

Tim Volodine is working on sensors in Chromium

scribe: also Riju from Intel has implemented Ambient Light

<fjh> ScribeNick: fjh

anssik: issues are performance and discovery

tobie: need to know which sensors are available and what is cost, do it sync or async

anssiK; not just entry point issue

tobie: does presence of API imply that sensor exists?
... all same question, need to understand life cycle of sensor vs lifecycle of page
... main issue is knowing whether sensor is there or not

anssik: generic sensor api designed from node.js perspective

tobie: simple API vs performance

Claes: in web of things interest group, what is connection to that group

… using REST APIs

<Zakim> tobie, you wanted to comment on IoT

tobie: Dave Raggett (dsr) shared presentation with me from his Munich, will look at it

Claes: might help mapping concrete Javascript APIs to generic sensor apis

tobie: can you please open github issue

Claes: yes

<anssik> fjh: producing a draft spec sounds like a good next step

<Claes> Need to drop off now. Bye

<anssik> ... allows us to get feedback from people now on calls

will have calls as needed but expect much work will be async, on list

<anssik> tobie: teting end of May for the draft spec

<anssik> anssik: feedback from both Node/io.js and browser implementers would be very welcome early in the process

anssik: tobie if you have list of issues related to performance I could share with our internal team
... issue #9 re event targets is performance consideration

… what are other issues on critical

suggest you ask about issues on list anssik, tobie can answer on list

Battery

fjh: anything new?

anssik: update from Intel QA re tests - looking at root cause for test failures, will report to the list

… not sure if issue is with test harness or test cases, so need to look into it.

… still pending mozilla implementation update as well, no apparent activity

I suggest that on a call we review github decisions and resolve them in conjunction with discussing the draft, thus avoiding a purely administrative discussion and linking with real work
