'user' have 1-n rows group.id = user.group_id. example result: group.id, group.name, user.email, user.default, user.updated_datetime 1, 'test', 'email', '0', '2015-06-10 12:00' 2, 'other', 'email', 1', '2015-06-08 10:00' both tables contain lot of data i'd prefer join's , not subqueries. know how subqueries i'm having trouble doing joins since grouping has multiple conditions. i'm fine doing aliases, eg: select a.* (query) i&#

i use webrtc in scenario in client video stream recorded on third-party server https://tokbox.com/ . put kind of watermark in recorded video. investigation brought me page http://w3c.github.io/webrtc-pc/#mediastreamtrack , seems technically possible since says that: a mediastream acquired using getusermedia() is, default, accessible application. means application able access contents of tracks, modify content, , send media peer chooses. this need, didn't find examples or explanation of function. i'd advice webrtc experts. you need use canvas route video getusermedia to, modify there, , use canvas.capturestream() turn mediastream. great - except canvas.capturestream(), while agreed in wg hasn't been included in spec yet. (there's pull request proposed verbiage mozilla wrote.) as far implementations: initial implementation of capturestream() landed in firefox nightly (41), , it's still behind pref until bug or 2 fixed. can enable canvas.ca

i wondering how pass link {{t}} helper. using v3.0.1 of ember i18n @ moment. obviously cannot pass link helper t helper (something like {{ t "some-translation-string" link={{#link-to 'page' model}}page{{/link-to}} }} won't work of course). so thinking, maybe can create custom prop returns whole link. again, how create link?. know of method has same arguments link-to helper, returns link (in case 'page' , model )? you might able achieve basic link, doubt you'll able toss live link-to component inside translation. so instead split translation string pieces: {{t 'gotosettingpage-before'}} {{link-to (t 'gotosettingpage-link') 'route.name'}} {{t 'gotosettingpage-after'}} 'gotosettingpage-before': 'go to' 'gotosettingpage-link': 'settings' 'gotosettingpage-after': 'page.'
