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,

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

Oliver, 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 Oliver Grawert

when you login. On Ubuntu Touch the same thing must

only
time when notifications directly from the app work is
while you are using it actively ... ciao oli
