Re: [Development] Override user agent string in WebApp

  Thread Previous • Date Previous • • Thread Next
Really exciting to see the way things are developing with Ubuntu Personal. Just found last night on my Nexus 7 that Windowed mode isn't restricted - awesome. Was able to multi-task with no issues. Also loving the battery life of my BQ, and accept that wouldn't be possible with the 'standard' model of multi-tasking now prevalent with other systems.
I remember when the ipad first came out - there was lots of sneering that it couldn't multi-task. IOS too in general had that restriction. It changed over time however - I look forward to seeing the evolution with Ubuntu Personal, and finding better ways to do things. It's interesting seeing this balance being struck. 

Nathan, the other week you wrote this:
--------------------
In Ubuntu, convergence means being the best it can be on each form factor with no compromises, and the ability for a single application to adapt instantly and seamlessly to each form factor.
Ubuntu's designers are working on the exact desktop story and where this all fits in. It's never been done before and nobody else is trying. It's going to be an exciting year. 
--------------------
I'm interested in your thoughts here - isn't this what Microsoft is currently trying to do with Windows 10, or is their implementation different? 

Cheers,

Mitchell

What you see there is one of the first steps of what's still a work in progress. This raises questions that haven't been answered/ specced yet like should an application pulling data from the network stop doing that if it's not focused? Should it stop once you minimized it? Once it's covered by other windows?
OSX is doing something very similar, they call it AppNap: if an app is not in the foreground and not playing sound, it's suspended.
So if by "multi-tasking" we're talking everything running at once and consuming power, then yes that is going the way of the bengal tiger, to go by a more accurate analogy, it will exist but as a corner case.
But don't equal this work with losing all of the mentioned features. We're just moving to smarter and more efficient ways of doing things.

I think currently when you are in windowed mode, apps are not suspended
and all runs simultaneously except I think the browser.
This is what I noticed on my Nexus 7 so everything seems
a lot more sluggish when in windowed mode. :)
Now my question too, is how application confinement and multiple application instance 
will be handled.

So what's the plan then for convergence? I get that battery life is important for phones and tablets - heck, probably many IOT devices as well. Battery life however is NOT crucial for desktop machines, and probably never will be. What is crucial however is real multi-tasking...
I get why Ubuntu Touch devices currently have awesome battery life - I get application confinement, and I understand the concept of having background services on an OS level that apps can plug into. Very clean and neat. What I don't currently understand is what will happen on desktops, or with a phone when docked.
I'm typing this on my "insecure" laptop running 15.04, with no application confinement. I have multiple browser tabs open, all of which are doing something. I have several terminals open with scrolling text, with processes I can peek at when I want to know what's going on. I have 4 downloads happening in the background, and an email client across 5 accounts that is constantly checking for emails. When I open a window and start a process, I know that it continues without me staring at it the whole time.
How does pausing an application's process when it's not in focus add to the current desktop usage scenario that most users now expect? My laptop is plugged in with a cable right now - battery life isn't important. How is Ubuntu Personal going to address this? There's no way we can compete with Windows and Apple - let alone most other Linux Distros, if multi-tasking goes the way of the Dodo. Would love to hear how this is going to be addresses - think Ubuntu on my Nexus & BQ devices is truly awesome - but the same concept on the desktop? Meh... I'm waiting to be convinced. 

Cheers,

Mitchell

Hey Peter,
When you say desktop right now that basically means X11 without any confinement in place and no lifecycle enforcement, so applications run happily and battery wastfully in the background at all times.
On the other hand anything running Ubuntu Personal with Mir as the display server, which is most likely a phone (but can also be a tablet or desktop if you're adventorous) pauses apps once they go into the background. They won't be able to keep track of updates let alone send a notification. This is why push notifications are needed. A background service will do the checking for updates and bring the application in the foreground if the user opens the notification. 

Hope that makes things a bit clearer.

    Christian

Ouch, that's unfortunate. Users are already requesting notifications as a feature. Why is it possible to have desktop notifications on an Ubuntu desktop machine, and it's not possible on Ubuntu Touch? Are we using two different implementations here and there? (How is convergence going to work if the two worlds behave differently?) Would be good to know, Peter 2015-08-13 22:03 GMT+02:00 Niklas Wenzel <nikwen.developer@xxxxxxxxx> <mailto:nikwen.developer@xxxxxxxxx>: 

    Yes, the Gmail notifications are created by the account-polld
    background service. That logic has nothing to do with the
    webapp. Am Do, 13. Aug, 2015 um 10:02 schrieb Peter Bittner

    I see that Gmail (the WebApp?) has push notifications on my
    device. Is this maybe related to the Online Accounts, and not
    the WebApp? Because the Gmail WebApp only has "accounts" as a
    policy group, nothing else. Peter 2015-08-13 17:54 GMT+02:00

    Bittner: permission when you login. On Ubuntu Touch the same
    thing must happen. I'm not sure I have seen this before (in a
    WebApp). except that your app is suspended when it is not
    having the focus or the screen is locked ... so the only time
    when notifications directly from the app work is while you are
using it actively ... ciao oli
