"let the user decide" is one of the reasons why foss fails with
inexperienced users, plus, you really don't want that extra level
of complexity on a phone.
The game doesn't really need to run in the background when it is
not being played. You will just do design your game loop around
that, but, in a server - client architecture, the update loop is
on the server most of the time, so... No problem there.
I guess the only valid argument is the one with the loading
browsers. Modern browsers don't repaint inactive tabs anyway, but
javascript still runs and eats cycles you'd really wanna keep. If
Ubuntu's gonna have something for that, it's gonna be a big plus.

Hey there,
you might be interested in:

https://docs.google.com/a/canonical.com/document/d/1ij8RtPsR_eYMW3mys8Gu1Y2CVFZpjXdMpdIjIGZ1SCA/edit#
In summary: We will implement a very strict
lifecycle policy, too, and
one that seamlessly adapts and extends to
different form-factors.
Thanks,

Hey guys,
What I find interesting in the iPad (I just
have one because I need it
for
work) and recently in Mac OS Mavericks is
their power managent policy.
Put simply, in iOS, except a few very special
cases, you applications
will
be stopped when they go into background. So
the foreground app gets full
reign of both memory and CPU. This also has a
very beneficial effect on
battery life - in Android, apps running in
the background still eat
cputime.
What OS X Mavericks is doing is taking this
idea further into a
noteboook
environment [1] with their application nap
and timer coalescing. You
really
only get the most out of your battery.
While this might not totally work in an
environment like Ubuntu, would
it be
possible to throttle the foreground
application and slow down the
background
ones? What would this imply? Is it do-able
in the current state of
Ubuntu
Phone, or do we need extra things at kernel
level?

Sincerely,
Josh
So, using a common example of an IM client or media
player - would we assume
that would stay in "unfocused" state? You mention
that only core apps can
run as background - that would mean it's not a valid
state for a normal 3rd
party app.
Even core apps will not be allowed to run in background.
We have an
exit strategy in terms of the flag described in the
document, but we
will most likely not use it. However, we will provide
services within
the system (media playback, downloads, alarms) to allow
apps to
describe specific background operations. We will extend
the list of
supported operations over time.
HTH,
Thomas
I would suggest that we want to fall closer to Android's app
model than Apple's - or perhaps let the user decide how
heavily it policies background apps. A mobile can get by with
very limited background apps - but a tablet will not. My
android tablet frequently has multiple apps running that I
switch between regularly, from allowing a slow website to
load while I'm writing a doc to a game that I pause so I can
look up a hint.
Let's not paint ourselves into a corner before we even start.
