magnus-plus photo: an application that combines a camera-based magnifier with more advanced image processing techniques, that would enable one to: 
- use it as a magnifier (with optional light from the camera LED). 
- use it as a photo negatives lightbox that automatically inverts the negatives and adjusts the colors for proper display:
the user just have to hover it over the (back-lit) negatives and on the screen the corresponding positive (or magnified part of it) is displayed in real-time. 
- use it as an EVF add-on to SLRs to help with manual focus, leveraging the possibility of amplifying contrast and magnifying.

Making a small and smart mobile widgets toolkit on top of plain QWidget + CSS for styling, named MWTk.
And using this toolkit to make several apps for MeeGo (and runs onto Maemo5 and Symbian too, even on desktop OS) and a new environment, that aims to be a good alternative to default MeeGo Handset UX, bringing it on pair with Harmattan UX, by giving it a successor to the deprecated MeeGoTouchFramework.
Already some testable sources can be found on the project gitorious repos.
https://gitorious.org/meego-community-mobile-ux-ng
And there is a page with some screenshots of the look that MTWk can do (this page will be moved on gitorious wiki soon) :

I plan to develop FM RDS applications with focus in the new standards from RadioDNS like the RadioVIS (partly based in the already existent the N900-fmvis http://code.google.com/p/n900-fmvis/).
I'm a member of a university radio station (Radio Muda FM, 88.5MHz) and my plan is to develop "real life" radio station applications. 
I'll also rewrite an application I did for audio streaming, darknow (a gui for darkice, http://darksnow.radiolivre.org) which is an icecast2 client, and also write an audio/video icecast2 client (based in a software I did called theorur, http://theorur.sarava.org), all using QT.

Lamikr: /* Reducing App Startup time */

= CE Performance page =
== UX & Performance team ==
* Communications
** IRC-channel #meego-arm at freenode
** CE daily meetings (time tbd)
** meego-handset mailing list
* Contributors
** Vesa-Matti Hartikainen IRC-nick: veskuh
** Vijay Nayani IRC-nick: vnayani
** Timo Rongas IRC-nick: ronksu
** Miroslav Safr IRC-nick: mirek or mirek2
** Gary Birkett IRC-nick: lcuk

== Problems ==

* Startup time of applications
* Right after the homescreen has loaded, after the first boot, device is unusable for a while
* Memory use
* UI scrolling freezes for 1-2s from time to time
* Startup time of the device

== Task list ==
=== UX fixes ===
'''Tasks'''
* Theming bugs
* Localization issues (Apps team in apps, gabor, zgyarmati in control panels)
* SMS does not not notify user (mkainu)
* Orientation issue with meego-ux-apps (Ronksu)
* Close button for meego-ux based apps (selesnie)
** This should be done on generic component itself, not to individual apps
* Remove systemui looking bar from meego-ux apps (it's confusing since it is not fully functional)

'''Tasks Done'''
* Meta bug for UX and usability issues for Summer Release created:
[http://bugs.meego.com/show_bug.cgi?id=18862 Bug 18862] - [META] [DE] UX glitches and bad usability in N900 DE Summer Release

=== Reducing App Startup time ===
'''Tasks'''

* last resort type of thing: taking NAND to use as swap (and destroying maemo installation)
* Investigate impact of Locale parsing (see #Locale further down)

'''Tasks Done'''
* Investigate effect on newer booster
** For boosted MTF apps, slightly less memory use for daemons, no improvement in startup (veskuh)
** For meego-ux apps, not yet working (msugano)
* Investigate I/O priorities of daemons
** Should be ok, or maybe themedaemon's could be icnreased
* Investigate if booster really helps (veskuh)
** Helps about 2s for widgetsgallery and settings (MTF apps that know how to utilize it properly)
** first launch of settings (duicontrolpanel) with booster: 4 sec, launches after that: 2.5 sec
** first launch of settings (duicontrolpanel) without booster: 6 sec, launches after that: 3 sec
** Does not help others. => booster-m can be disabled
* launcher set I/O priority to IDLE for home this slows down startup of apps. Increase it to Normal (stskeeps)
* eMMC performance investigation, maemo is 2-20x faster? see [https://bugs.meego.com/show_bug.cgi?id=18295 bug #18295] (Q/A team to rerun the tests)
** Not that much slower, and in fact many cases faster
* eMMC vs. MMC, according to Sage, no major difference in old experiments

=== Reducing memory use ===
'''Tasks'''

* Merge meego-volume-control to systemui (jpeltonen)
* adjust stack sizes
* zram (formerly known as ramzswap and compcache) trial (tazpa)
* remove mdecorator

'''Tasks Done'''
* lower GLES ParamBuffer size (veskuh)
* Investigtate GLES ParamBuffer size
** @1MB ParamBuffer for widgetsgallery uses ~1.5MB total memory reduction, ~2.5MB less private memory, and ~1MB more shared memory (measuerd with smaps)
** @1MB ParamBuffer ~10MB increase in available memory (free + buffers + cache) measured with top after boot
* meego-ux to drop GL-context: https://bugs.meego.com/show_bug.cgi?id=18268
* Remove unused applifed processes. (Ronksu)

=== Improving first boot ===
'''Tasks'''
* Reduce the number of .desktop files and icons meegohome scans at first boot (vnayani)

'''Tasks Done'''
* delay start of tracker indexing (maitrey)
* System does this already: reduce I/O priority of tracker-miner and tracker-store (use ionice to to launch)

'''Not doable'''
* tracker to preindex filesystem to improve first boot. see [https://bugs.meego.com/show_bug.cgi?id=18759 bug #18759] (maitrey)

=== Improving system startup ===
'''Tasks'''
* Reduce the list of [[ARM/N900/Performance/autostart|autostarted apps.]]
* tracker configuration (maitrey)

'''Tasks Done'''
* autostarted backlight setup.desktop file removed from the nokia-n900-configs (mce handles backlight) (lamikr)
* bootchart generated svg from the N900 processes starting up attached to bug https://bugs.meego.com/show_bug.cgi?id=9527 (lamikr)
* avahi changed to started on demand via dbus service file instead of launching automatically. (lamikr) [https://bugs.meego.com/show_bug.cgi?id=19297]
* fixed the meegotouch-home io-priority. Affects to all apps launched from desktop. (stskeeps)
* Delay the startup of dialer, trackers, etc. to happen once destop is ready (lamikr) [https://bugs.meego.com/show_bug.cgi?id=19287]

=== Improving UI Performance ===
'''Tasks'''
* Check if newer MTF improves performance (mirek)
* Check if newer Qt improves performance
'''Tasks Done'''

=== Misc ===
'''Tasks'''
* optimizing MTF packages, there might be some configuration options, etc.?
* CGROUPS optimization, most likely still not done
* cache some often used data in NAND and symlink there
* real microsdhc tests based on class speed rating
** actually answer specific questions about how write/read speed effect perf
*** app startup times
*** general usage
*** media write times
*** cataloguing media
* Swap on memory card (probably will not help if the os is on the card also, otherwise might)
* Taking fennec more frequently from upstream beta repository http://lists.meego.com/pipermail/meego-handset/2011-June/000467.html
* Profile startup of simple MTF, QML, and Qt apps
* Profile memory use of simple MTF, QML, and Qt apps
* Investigate configuration options for MTF
* Investigate configuration options for Qt
* Investigate configuration options for QML
* Update MTF (libmeegotouch, mcompositor, home, system ui, etc. ) to get latest optimizations from upstream (mirek)
* Update Qt
'''Tasks Done'''
* test overclock with known testing (from qa-tools guys perhaps)
** kjokinie: Tested on my set up boot-times with some [[ARM/N900/Performance/OverclockBootTimeTest | overclock configurations]] already
*** practically it does not help at least boot time
*** however, at least audio player seemed much more responsive, so application performances should still be tested by QA.
* Carsten tweaked kernel virtual memory settings (increased swappiness), Fennec bootup improved a lot and also system responsivness
* thumbnails images for pre-installed images should be done during the build time. (Now thumbnails are generated only when user wants to get the image list and that takes times)

== Benchmark results ==
* Results from Q/A http://wiki.meego.com/ARM/N900/QA/Performance
* Different class SD card benchmarking
** [[File:SDcard_benchmarking_060611.jpg]]
** Used image 05-30.1 acceptance image
** With class 10 card image worked really unstable. Measurements were got after several tries.
** Current class10 measurements are not comparable but give somekind of direction
* SunSpider (JavaScript performance
** 6.1s with GPE MiniBrowser (image DE.2011-05-30 acceptance)
** 6.8s with Fennec (image DE.2011-05-30 acceptance)
** These are actually pretty good results. Indicates that raw CPU perfomance is ok.

** by removing the applauncherd (process starting booster-m) and tracker-store and delaying the dialer ui (40000 kb) launch by 30 second, bootup time will improved from 72 second to 59.

== Locale Parsing ==

Currently inside N900-CE image, the folder /usr/share/locale contains over 500 items many of these are placeholders for real language support and do not contain much.
Veskuh said that we only include the Community translations in this image.

Having such a cluttered folder with placemarks only puts a negative impact in file system performance and app startup time.
In rough tests, removing this folder improves startup time.

Proper analysis of this is required and a compromise where translations are still working but without wasted space is important.

For later investigation, find other filesystem hotspots which have similar large folders full of placeholders.

== Problems ==

* Startup time of applications
* Right after the homescreen has loaded, after the first boot, device is unusable for a while
* Memory use
* UI scrolling freezes for 1-2s from time to time
* Startup time of the device

== Task list ==
=== UX fixes ===
'''Tasks'''
* Theming bugs
* Localization issues (Apps team in apps, gabor, zgyarmati in control panels)
* SMS does not not notify user (mkainu)
* Orientation issue with meego-ux-apps (Ronksu)
* Close button for meego-ux based apps (selesnie)
** This should be done on generic component itself, not to individual apps
* Remove systemui looking bar from meego-ux apps (it's confusing since it is not fully functional)

'''Tasks Done'''
* Meta bug for UX and usability issues for Summer Release created:
[http://bugs.meego.com/show_bug.cgi?id=18862 Bug 18862] - [META] [DE] UX glitches and bad usability in N900 DE Summer Release

=== Reducing App Startup time ===
'''Tasks'''

* last resort type of thing: taking NAND to use as swap (and destroying maemo installation)
* Investigate impact of Locale parsing (see #Locale further down)

'''Tasks Done'''
* Investigate effect on newer booster
** For boosted MTF apps, slightly less memory use for daemons, no improvement in startup (veskuh)
** For meego-ux apps, not yet working (msugano)
* Investigate I/O priorities of daemons
** Should be ok, or maybe themedaemon's could be icnreased
* Investigate if booster really helps (veskuh)
** Helps about 2s for widgetsgallery and settings (MTF apps that know how to utilze it properly)
** Does not help others. => booster-m can be disabled
* launcher set I/O priority to IDLE for home this slows down startup of apps. Increase it to Normal (stskeeps)
* eMMC performance investigation, maemo is 2-20x faster? see [https://bugs.meego.com/show_bug.cgi?id=18295 bug #18295] (Q/A team to rerun the tests)
** Not that much slower, and in fact many cases faster
* eMMC vs. MMC, according to Sage, no major difference in old experiments

=== Reducing memory use ===
'''Tasks'''

* Merge meego-volume-control to systemui (jpeltonen)
* adjust stack sizes
* zram (formerly known as ramzswap and compcache) trial (tazpa)
* remove mdecorator

'''Tasks Done'''
* lower GLES ParamBuffer size (veskuh)
* Investigtate GLES ParamBuffer size
** @1MB ParamBuffer for widgetsgallery uses ~1.5MB total memory reduction, ~2.5MB less private memory, and ~1MB more shared memory (measuerd with smaps)
** @1MB ParamBuffer ~10MB increase in available memory (free + buffers + cache) measured with top after boot
* meego-ux to drop GL-context: https://bugs.meego.com/show_bug.cgi?id=18268
* Remove unused applifed processes. (Ronksu)

=== Improving first boot ===
'''Tasks'''
* Reduce the number of .desktop files and icons meegohome scans at first boot (vnayani)

'''Tasks Done'''
* delay start of tracker indexing (maitrey)
* System does this already: reduce I/O priority of tracker-miner and tracker-store (use ionice to to launch)

'''Not doable'''
* tracker to preindex filesystem to improve first boot. see [https://bugs.meego.com/show_bug.cgi?id=18759 bug #18759] (maitrey)

=== Improving system startup ===
'''Tasks'''
* Reduce the list of [[ARM/N900/Performance/autostart|autostarted apps.]]
* tracker configuration (maitrey)

'''Tasks Done'''
* autostarted backlight setup.desktop file removed from the nokia-n900-configs (mce handles backlight) (lamikr)
* bootchart generated svg from the N900 processes starting up attached to bug https://bugs.meego.com/show_bug.cgi?id=9527 (lamikr)
* avahi changed to started on demand via dbus service file instead of launching automatically. (lamikr) [https://bugs.meego.com/show_bug.cgi?id=19297]
* fixed the meegotouch-home io-priority. Affects to all apps launched from desktop. (stskeeps)
* Delay the startup of dialer, trackers, etc. to happen once destop is ready (lamikr) [https://bugs.meego.com/show_bug.cgi?id=19287]

=== Improving UI Performance ===
'''Tasks'''
* Check if newer MTF improves performance (mirek)
* Check if newer Qt improves performance
'''Tasks Done'''

=== Misc ===
'''Tasks'''
* optimizing MTF packages, there might be some configuration options, etc.?
* CGROUPS optimization, most likely still not done
* cache some often used data in NAND and symlink there
* real microsdhc tests based on class speed rating
** actually answer specific questions about how write/read speed effect perf
*** app startup times
*** general usage
*** media write times
*** cataloguing media
* Swap on memory card (probably will not help if the os is on the card also, otherwise might)
* Taking fennec more frequently from upstream beta repository http://lists.meego.com/pipermail/meego-handset/2011-June/000467.html
* Profile startup of simple MTF, QML, and Qt apps
* Profile memory use of simple MTF, QML, and Qt apps
* Investigate configuration options for MTF
* Investigate configuration options for Qt
* Investigate configuration options for QML
* Update MTF (libmeegotouch, mcompositor, home, system ui, etc. ) to get latest optimizations from upstream (mirek)
* Update Qt
'''Tasks Done'''
* test overclock with known testing (from qa-tools guys perhaps)
** kjokinie: Tested on my set up boot-times with some [[ARM/N900/Performance/OverclockBootTimeTest | overclock configurations]] already
*** practically it does not help at least boot time
*** however, at least audio player seemed much more responsive, so application performances should still be tested by QA.
* Carsten tweaked kernel virtual memory settings (increased swappiness), Fennec bootup improved a lot and also system responsivness
* thumbnails images for pre-installed images should be done during the build time. (Now thumbnails are generated only when user wants to get the image list and that takes times)

== Benchmark results ==
* Results from Q/A http://wiki.meego.com/ARM/N900/QA/Performance
* Different class SD card benchmarking
** [[File:SDcard_benchmarking_060611.jpg]]
** Used image 05-30.1 acceptance image
** With class 10 card image worked really unstable. Measurements were got after several tries.
** Current class10 measurements are not comparable but give somekind of direction
* SunSpider (JavaScript performance
** 6.1s with GPE MiniBrowser (image DE.2011-05-30 acceptance)
** 6.8s with Fennec (image DE.2011-05-30 acceptance)
** These are actually pretty good results. Indicates that raw CPU perfomance is ok.

* Conclusion: meego-volume-control went down from 26000 kb to 3440 thanks for the qml ripout
* Can we reduce the mem usage of processes like sysuid, mdecorator, mthemedaemon
* Is booster-m really improving our performance as it takes itself a lot of from our memory that we do not have any extra without swapping?
** by removing the applauncherd (process starting booster-m) and tracker-store and delaying the dialer ui (40000 kb) launch by 30 second, bootup time will improved from 72 second to 59.

Lamikr: /* Improving system startup */

= CE Performance page =
== UX & Performance team ==
* Communications
** IRC-channel #meego-arm at freenode
** CE daily meetings (time tbd)
** meego-handset mailing list
* Contributors
** Vesa-Matti Hartikainen IRC-nick: veskuh
** Vijay Nayani IRC-nick: vnayani
** Timo Rongas IRC-nick: ronksu
** Miroslav Safr IRC-nick: mirek or mirek2

== Problems ==

* Startup time of applications
* Right after the homescreen has loaded, after the first boot, device is unusable for a while
* Memory use
* UI scrolling freezes for 1-2s from time to time
* Startup time of the device

== Task list ==
=== UX fixes ===
'''Tasks'''
* Theming bugs
* Localization issues (Apps team)
* SMS does not not notify user (mkainu)
* Orientation issue with meego-ux-apps (Ronksu)
* Close button for meego-ux based apps (selesnie)
** This should be done on generic component itself, not to individual apps
* Remove systemui looking bar from meego-ux apps (it's confusing since it is not fully functional)

'''Tasks Done'''
* Meta bug for UX and usability issues for Summer Release created:
[http://bugs.meego.com/show_bug.cgi?id=18862 Bug 18862] - [META] [DE] UX glitches and bad usability in N900 DE Summer Release

=== Reducing App Startup time ===
'''Tasks'''

* last resort type of thing: taking NAND to use as swap (and destroying maemo installation)
* Investigate I/O priorities of daemon's

'''Tasks Done'''
* Investigate if booster really helps (veskuh)
** Helps about 2s for widgetsgallery and settings (MTF apps that know how to utilze it properly)
* launcher set I/O priority to IDLE for home this slows down startup of apps. Increase it to Normal (stskeeps)
* eMMC performance investigation, maemo is 2-20x faster? see [https://bugs.meego.com/show_bug.cgi?id=18295 bug #18295] (Q/A team to rerun the tests)
** Not that much slower, and in fact many cases faster
* eMMC vs. MMC, according to Sage, no major difference in old experiments

=== Reducing memory use ===
'''Tasks'''
* lower GLES ParamBuffer size (veskuh)
* Merge meego-volume-control to systemui (jpeltonen)
* adjust stack sizes
* zram (formerly known as ramzswap and compcache) trial (tazpa)
* remove mdecorator

'''Tasks Done'''
* Investigtate GLES ParamBuffer size
** @1MB ParamBuffer for widgetsgallery uses ~1.5MB total memory reduction, ~2.5MB less private memory, and ~1MB more shared memory (measuerd with smaps)
** @1MB ParamBuffer ~10MB increase in available memory (free + buffers + cache) measured with top after boot
* meego-ux to drop GL-context: https://bugs.meego.com/show_bug.cgi?id=18268
* Remove unused applifed processes. (Ronksu)

=== Improving first boot ===
'''Tasks'''
* Reduce the number of .desktop files and icons meegohome scans at first boot (vnayani)

'''Tasks Done'''
* delay start of tracker indexing (maitrey)
* System does this already: reduce I/O priority of tracker-miner and tracker-store (use ionice to to launch)

'''Not doable'''
* tracker to preindex filesystem to improve first boot. see [https://bugs.meego.com/show_bug.cgi?id=18759 bug #18759] (maitrey)

=== Improving system startup ===
'''Tasks'''
* Reduce the list of [[ARM/N900/Performance/autostart|autostarted apps.]]
* Delay the startup of dialer, trackers, etc. to happen once destop is ready (lamikr) [https://bugs.meego.com/show_bug.cgi?id=19287]
* tracker configuration (maitrey)

'''Tasks Done'''
* autostarted backlight setup.desktop file removed from the nokia-n900-configs (mce handles backlight) (lamikr)
* bootchart generated svg from the N900 processes starting up attached to bug https://bugs.meego.com/show_bug.cgi?id=9527 (lamikr)
* avahi changed to started on demand via dbus service file instead of launching automatically. (lamikr)
* fixed the meegotouch-home io-priority. Affects to all apps launched from desktop. (stskeeps)

=== Improving UI Performance ===
'''Tasks'''
* Check if newer MTF improves performance (mirek)
* Check if newer Qt improves performance
'''Tasks Done'''

=== Misc ===
'''Tasks'''
* optimizing MTF packages, there might be some configuration options, etc.?
* CGROUPS optimization, most likely still not done
* cache some often used data in NAND and symlink there
* real microsdhc tests based on class speed rating
** actually answer specific questions about how write/read speed effect perf
*** app startup times
*** general usage
*** media write times
*** cataloguing media
* Swap on memory card (probably will not help if the os is on the card also, otherwise might)
* Taking fennec more frequently from upstream beta repository http://lists.meego.com/pipermail/meego-handset/2011-June/000467.html
* Profile startup of simple MTF, QML, and Qt apps
* Profile memory use of simple MTF, QML, and Qt apps
* Investigate configuration options for MTF
* Investigate configuration options for Qt
* Investigate configuration options for QML
* Update MTF (libmeegotouch, mcompositor, home, system ui, etc. ) to get latest optimizations from upstream (mirek)
* Update Qt
'''Tasks Done'''
* test overclock with known testing (from qa-tools guys perhaps)
** kjokinie: Tested on my set up boot-times with some [[ARM/N900/Performance/OverclockBootTimeTest | overclock configurations]] already
*** practically it does not help at least boot time
*** however, at least audio player seemed much more responsive, so application performances should still be tested by QA.
* Carsten tweaked kernel virtual memory settings (increased swappiness), Fennec bootup improved a lot and also system responsivness
* thumbnails images for pre-installed images should be done during the build time. (Now thumbnails are generated only when user wants to get the image list and that takes times)

== Benchmark results ==
* Results from Q/A http://wiki.meego.com/ARM/N900/QA/Performance
* Different class SD card benchmarking
** [[File:SDcard_benchmarking_060611.jpg]]
** Used image 05-30.1 acceptance image
** With class 10 card image worked really unstable. Measurements were got after several tries.
** Current class10 measurements are not comparable but give somekind of direction
* SunSpider (JavaScript performance
** 6.1s with GPE MiniBrowser (image DE.2011-05-30 acceptance)
** 6.8s with Fennec (image DE.2011-05-30 acceptance)
** These are actually pretty good results. Indicates that raw CPU perfomance is ok.

* Startup time of applications
* Startup time of the device
* Right after the homescreen has loaded, after the first boot, device is unusable for a while
* Memory use
* Slow I/O performance 2-20x slower than Maemo5 on N900
* UI scrolling freezes for 1-2s from time to time

== Task list ==
=== UX fixes ===
'''Tasks'''
* Collect bugs to metabug (Kristiine)
* Theming bugs
* Localization issues (Apps team)
* Close button for meego-ux based apps (selesnie)
** This should be done on generic component itself, not to individual apps
* Remove systemui looking bar from meego-ux apps (it's confusing since it is not fully functional)

=== Reducing App Startup time ===
'''Tasks'''
* Investigate if booster really helps (veskuh)
* eMMC performance investigation, maemo is 2-20x faster? see [https://bugs.meego.com/show_bug.cgi?id=18295 bug #18295] (Q/A team to rerun the tests)
* last resort type of thing: taking NAND to use as swap (and destroying maemo installation)

'''Tasks Done'''
* eMMC vs. MMC, according to Sage, no major difference in old experiments

=== Reducing memory use ===
'''Tasks'''
* Remove unused applifed processes. (Ronksu)
* lower GLES ParamBuffer size (veskuh)
* Merge meego-volume-control to systemui (jpeltonen)

* ramzswap trial

'''Tasks Done'''
* meego-ux to drop GL-context: https://bugs.meego.com/show_bug.cgi?id=18268

=== Improving first boot ===
'''Tasks'''
* tracker to preindex filesystem to improve first boot. see [https://bugs.meego.com/show_bug.cgi?id=18759 bug #18759] (maitrey)

=== Improving UI Performance ===
'''Tasks'''
* Check if newer MTF improves performance (mirek)
* Check if newer Qt improves performance
'''Tasks Done'''

=== Misc ===
'''Tasks'''
* optimizing MTF packages, there might be some configuration options, etc.?
* CGROUPS optimization, most likely still not done
* cache some often used data in NAND and symlink there
* test overclock with known testing (from qa-tools guys perhaps)
** kjokinie: Tested on my set up boot-times with some [[ARM/N900/Performance/OverclockBootTimeTest | overclock configurations]] already
*** practically it does not help at least boot time
*** however, at least audio player seemed much more responsive, so application performances should still be tested by QA.
* real microsdhc tests based on class speed rating
** actually answer specific questions about how write/read speed effect perf
*** app startup times
*** general usage
*** media write times
*** cataloguing media
* Swap on memory card (probably will not help if the os is on the card also, otherwise might)
* Taking fennec more frequently from upstream beta repository http://lists.meego.com/pipermail/meego-handset/2011-June/000467.html
* Profile startup of simple MTF, QML, and Qt apps
* Profile memory use of simple MTF, QML, and Qt apps
* Investigate configuration options for MTF
* Investigate configuration options for Qt
* Investigate configuration options for QML
* Update MTF (libmeegotouch, mcompositor, home, system ui, etc. ) to get latest optimizations from upstream
* Update Qt
'''Tasks Done'''
* Carsten tweaked kernel virtual memory settings (increased swappiness), Fennec bootup improved a lot and also system responsivness
* thumbnails images for pre-installed images should be done during the build time. (Now thumbnails are generated only when user wants to get the image list and that takes times)

== Benchmark results ==
* Results from Q/A http://wiki.meego.com/ARM/N900/QA/Performance
* Different class SD card benchmarking
** [[File:SDcard_benchmarking_060611.jpg]]
** Used image 05-30.1 acceptance image
** With class 10 card image worked really unstable. Measurements were got after several tries.
** Current class10 measurements are not comparable but give somekind of direction
* SunSpider (JavaScript performance
** 6.1s with GPE MiniBrowser (image DE.2011-05-30 acceptance)
** 6.8s with Fennec (image DE.2011-05-30 acceptance)
** These are actually pretty good results. Indicates that raw CPU perfomance is ok.

* Conclusion: meego-volume-control went down from 26000 kb to 3440 thanks for the qml ripout
* Can we reduce the mem usage of processes like sysuid, mdecorator, mthemedaemon
* Is booster-m really improving our performance as it takes itself a lot of from our memory that we do not have any extra without swapping?
** by removing the applauncherd (process starting booster-m) and tracker-store and delaying the dialer ui (40000 kb) launch by 30 second, bootup time will improved from 72 second to 59.

* Conclusion: meego-volume-control went down from 26000 kb to 3440 thanks for the qml ripout
* Can we reduce the mem usage of processes like sysuid, mdecorator, mthemedaemon
* Is booster-m really improving our performance as it takes itself a lot of from our memory that we do not have any extra without swapping?
** by removing the applauncherd (process starting booster-m) and tracker-store and delaying the dialer ui (40000 kb) launch by 30 second, bootup time will improved from 72 second to 59.

* Conclusion: meego-volume-control went down from 26000 kb to 3440 thanks for the qml ripout
* Can we reduce the mem usage of processes like sysuid, mdecorator, mthemedaemon
* Is booster-m really improving our performance as it takes itself a lot of from our memory that we do not have any extra without swapping?
** by removing the applauncherd (process starting booster-m) and tracker-store and delaying the dialer ui (40000 kb) launch by 30 second, bootup time will improved from 72 second to 59.

=== Application Startup Locations ===

Applications are started automatically on MeeGo from following locations:

* /etc/inittab (running as root user)
* /etc/rc.sysinit (running as root user)
* /etc/init.d (running as root user)
* /etc/xdg/autostart (running as system user meego)

Then in addition of these locations applications can also be autostarted by sending dbus-message to application
which have dbus-service description in location:

* /usr/share/dbus-1/services

=== Test for removing apps from /etc/xdg/autostart ===

* Original Image
** boot up time: 72 sec (not a first boot which is slower)
* Original image with tracker removed from /etc/xdg/autostart
** boot up time: 69 sec
* Original image with tracker and meego-volume-control removed from /etc/xdg/autostart

These apps are candidates to be included in the DE configuration and/or should be put to [http://apps-beta.meego.com/repositories/ MeeGo apps]. Feel free to add your stuff, after you have verified it on current MeeGo 1.2 image on N900.

===MeeGo Community Extras Client===

https://gitorious.org/meego-community-extras-client

This would need to have OBS project?

===TwimGo, Kasvopus, Newsflow, Nelisquare===

QML apps by Tommi Laukkanen, packaging/tweaking for N900DE TBD (Tommi / Ville V).

Make sure you have date of the device correct. Either set it with control panel or from command line

zypper in com.substanceofcode.twimgo 
zypper in com.substanceofcode.newsflow 
zypper in com.substanceofcode.kasvopus 

Status: Kasvopus working OK. Twimgo needs to disable GPS (QtM API doesn't work). Newsflow was crashing. How about nelisquare?

===QmlReddit===
Reddit reader, works well on N900DE.

zypper addrepo -f http://repo.pub.meego.com/home:/vivainio/DE/home:vivainio.repo

zypper in info.vivainio.qmlreddit

Also in the repo:

zypper in info.vivainio.qatbowling

Status: Seems to work, coming to DE images.

===CacheMe===

An online geocaching application using Qt and QtMobility:
http://build.pub.meego.com/package/show?package=cacheme&project=home%3Aharbaum

Beware: This is actually untested on MeeGo, but works nicely in Symbian, Maemo5, Windows and Desktop Linux, so MeeGo should work. Please give feedback to harbaum@#meego-arm

Status: Can you please make step-by-step installation guide? Also I think Qt Mobility location will not work in N900. Also, we will need armv7hl binaries. (Jukka)

===Gluon===

** Other apps TBD, based on error status and user evaluation (jukka)
** Investigating possibility to include new MeeGo UX applications (Sage)
** Chat replaced with Peregrine (community app) (done)
** Facebook and Twitter clients from tlaukkanen? (vivainio needs to help)
* Application grid improvements
** Structure home screen icons to correct order (Sage)
** Finalize correct icons for applications (from base theme)(mirek)
* Theme improvements
** Work on DE theme, and fix UI glitches and bad usability (see [https://bugs.meego.com/show_bug.cgi?id=17039 META bug], mirek)
** New wallpaper for SF2011? (wazd?)
* Splash screens (msugano)
** Boot splash screen should stay on screen until device booted
** Shutdown splash should stay on screen until device is powered off
* Backlight behaviour (lamikr/done)
** Increase the timeout to 1min (done)
** Backlight should turn off only when power button is released. When powering the device off (keeping power button pressed), backlight shouldn't turn off (done)
** Backlight should not dim while booting, before the device is fully booted so that user sees when that happens (done)
* Automatic lock (lamikr/done)
** Screen and keys should be locked automatically after a time-out (done)
* Hardware key features
** Power button is used to toggle backlight, and for powering on and off (lamikr/done)
** Lock key works (lamikr/done)
** Camera key starts the Camera application (joonasta)
** Volume can be controlled with volume keys during call (jpeltonen)
* Media content
** Based on community contribution, can we have open source videos, ringtones, audio and images? (ask from karoliina salminen)

'''Implemented for the alpha release'''

* Theme: Development (ie. base theme), should show the new colourful new icons instead of default MeeGo ones. OK, there is a new DE theme based on base theme.
* Wallpaper: all black (need to make a 800x480 image for that?)
** Changing wallpaper from Settings should work
* Quick bar: Dialer, SMS, Browser, Camera
* Application grid: Dialer, SMS, Browser, Camera, Settings first and then the rest.
** remove current duplicate browser icons
** should include mad-developer
* Backlight turn off delay: 30s
* Boot splash screen
* Shutdown splash screen

=== Settings for experimental MeeGo UX (Tablet) ===
* Menu key mapped to N900 camera key (or proximity sensor?)
* Use Dialer, SMS and Browser from Handset UX.

=== Ideas, feedback ===
* When we get new artwork, we can use that [[ARM/N900/Artwork]]

ARM/N900/ReleaseProcess

2011-05-06T10:44:41Z

Lamikr:

This page describes the [[ARM/N900/DeveloperEdition|N900 Developer edition]] release process.

== Principles ==

* Everything we cannot get into MeeGo 1.2/will have significant difficulties getting into MeeGo 1.2 due to feature freeze will go into the N900 DE OBS project.
* Everything should ideally be contributed back to MeeGo 1.3 release track.
* We should stay ABI compatible with MeeGo 1.2.
* We should be aiming for providing a MeeGo compliant "product".

== Repository setup ==

We have two OBS projects on the [http://build.pub.meego.com Community OBS]:

* [https://build.pub.meego.com/project/show?project=Project%3ADE%3ATrunk Project:DE:Trunk] (stable repository)
* [https://build.pub.meego.com/project/show?project=Project%3ADE%3ATrunk:Testing Project:DE:Trunk:Testing] (staging repository)

Each of them has two build targets for the packages:

* 'standard', which points to the current state of the MeeGo 1.2 trunk which becomes next weekly.
* 'weekly', which points to MeeGo 1.2 weekly release.

This setup will allow us to look-ahead on upcoming issues caused by changes done in the MeeGo 1.2 trunk.

== Image building and testing matrix ==

MeeGo.com weekly release comes out on wednesdays. DE weekly release comes out on fridays.

Both sanity & acceptance tests are very brief run-throughs of the functionality of the entire MeeGo distribution, to assure that the basic health of the distribution and report major regressions at the earliest time. All the checkpoints in sanity & acceptance test reflect the most important and basic functionality of the distribution.

We do the sanity test against the Trunk and the acceptance test against Trunk:Testing.

{| class="wikitable" border=1
|-
! Day
! MeeGo.com 1.2 Trunk & Project:DE:Trunk
! MeeGo.com 1.2 Trunk & Project:DE:Trunk:Testing

| weekly release track sanity
| weekly release track acceptance
|-
| Friday (after weekly release, repository unfreezes)
| sanity
| acceptance
| weekly release track sanity, if OK, DE weekly release
|
|}

Rationale:

Weekly release == MeeGo 1.2 Trunk on wednesdays, so no need to have seperate images.

Weekly release acceptance testing needs to happen to make the fixes flow to weekly release fix.

"Normal" Sanity/acceptance serves to help prepare for next weeks changes.

== Procedures ==

=== Developer: Branch a package and submit changes to DE ===

Choose your origin (in the following, ORIGIN) of the package:

* MeeGo.com:MeeGo:1.2:oss (currently 1.2)
* Project:DE:Trunk:Testing (fix a package already contained in DE)

osc -A <nowiki>https://api.pub.meego.com</nowiki> branch -cm "To work on MeeGo DE" ORIGIN packagename

This creates home:yourusername:branches:ORIGIN.

Go to https://build.pub.meego.com/home/list_my and find your project.

If there is no repositories listed in Repositories tab,
go and click "add repository" and "advanced interface" and choose Project:DE:Trunk:Testing as project,
"standard" as repository, new name "standard" and architectures armv7el, armv8el and i586.

.. do your work

'''NOTE:''' Remember to add entry to .changes file and describe what your submit fixes. "- Fixes for BMC#1234" isn't enough, but "- photo-index.patch: Fixed segmentation fault when indexing photos (BMC#1234)" would do.

After your work is done, i.e., doing the changes to the package and after you have committed the changes to your branch, it is time to check that everything is like it should be. So, lets verify the diff between your branch and the target. NOTE: If you are submitting new package to Project:DE:Trunk:Testing the diff is most probably empty.

osc -A <nowiki>https://api.pub.meego.com</nowiki> submitreq -dm "." home:yourusername:branches:ORIGIN packagename Project:DE:Trunk:Testing

After you have confirmed that the diff is ok. It is time to submit the changes:

osc -A <nowiki>https://api.pub.meego.com</nowiki> submitreq -m "What you changed" home:yourusername:branches:ORIGIN packagename Project:DE:Trunk:Testing

As a result of this command you will get request id that corresponds the request. You can check your request from the OBS webui https://build.pub.meego.com/request/show/REQUEST_ID

=== Release engineering ===

If you'd like to help out with release engineering, poke Stskeeps / Carsten Munk on IRC.

General procedure for reviewing [https://build.pub.meego.com/project/list_requests?project=Project:DE:Trunk:Testing requests towards Project:DE:Trunk:Testing]:

* Verify the package actually builds in the origin project
* Review the package on basis of [[Packaging/Guidelines|packaging guidelines]]
* When accepting the change to Project:DE:Trunk:Testing make sure that there is existing package link already if the change is a patch is to package in MeeGo.com:Trunk
osc -A https://api.pub.meego.com linkpac -c MeeGo.com:Trunk <package> Project:DE:Trunk
osc -A https://api.pub.meego.com linkpac Project:DE:Trunk <package> Project:DE:Trunk:Testing
* After the link is created and review for the changes have been made you can accept the package. ''NOTE:'' It is recommended to ''Forward to Project:DE:Trunk'' (but not accept the package in Project:DE:Trunk) instead of just ''Accept'' the package to make sure it ends up to the Project:DE:Trunk project eventually.

Conditions and procedure for accepting a package change into Project:DE:Trunk from Project:DE:Trunk:Testing:
* The package change must not break any compilation in Trunk:Testing
* The package change must have been included in one acceptance testing image and no regressions seen because of it by QA.
* When OK, submit package to Project:DE:Trunk and remove package from Project:DE:Trunk:Testing (use UI).
* Only accept changes to Project:DE:Trunk that fix issues towards maintaining quality of the weekly image release from Wednesday to Friday weekly release time (soft freeze)
* Accept in the [https://build.pub.meego.com/project/list_requests?project=Project:DE:Trunk requests list towards Project:DE:Trunk]
* Decline any changes made directly to Project:DE:Trunk not done from Project:DE:Trunk:Testing.

==== Image creation ====

Multiple options, we are currently looking at having the images physically built in internal Nokia IMG service and transferred to a public download site.

==== Image configurations ====

N900 DE image configurations (kickstart files) are located at https://gitorious.org/meego-developer-edition-for-n900/image-configurations gitorious tree under the kickstarts directory.

==== Daily image creator ====

From the git tree above the images are created by daily-image-builder, which is available at https://gitorious.org/image-building-tools/daily-image-builder

daily-image-builder script is executed every morning on computer X from where the images are uploaded to http://repository.maemo.org/meego/n900-de/daily/ around UTC 03:00.

==== Release Format ====

The directories in n900-de repository look following 1.1.99.2.20110412.6.DE.2011-04-19.2 where the start is the MeeGo version and the end after DE is the DE build version in following format YYYY-MM-DD.<build_count>

The MeeGo version is taken from http://download.meego.com/trunk-daily/builds/trunk/

==== Images ====

Currently we have couple of different images types:

mg-handset-armv7nhl-n900-de-sanity
mg-handset-armv7nhl-n900-de-acceptance
mg-tablet-armv7nhl-n900-de-acceptance

All the images use MeeGo Trunk (later on MeeGo 1.2) daily repository as a base. So no Trunk:Testing packages are used. This pretty much means that DE images are closest to the MeeGo sanity test report results. In DE case the sanity and acceptance in image name means which DE repository we are using in addition to the MeeGo Trunk, i.e., in sanity images we use Project:DE:Trunk repository and in acceptance Project:DE:Trunk:Testing repository.

Tablet image uses also Project:DE:Devel:Tablet repository for some n900 tablet specific modifications.

== The team and the work ==

This hardware adaptation team maintains the port of MeeGo for the N900.

Due to the use of closed components in the hardware adaptation, this team
cannot run fully in the open. However, it will strive to minimize the
non-openness in its work related to those components and the number of
those components. Closed components will be maintained exclusively
by employees and subcontractors of Nokia.

Anyone is welcome to contribute and non-member contributions will be treated
with same process and review as member contributions.

We will be adding members to the team based on merit, by acceptance by
team lead after proposal on the agenda for a sync meeting.

Team communication is in English.

[[ARM/N900/Meetings|Team synchronisation meetings are held in #meego-meeting on irc.freenode.net]] every other Thursday at 9.00 EEST (8.00 CEST, 6.00 UTC, Wednesday 23.00 PDT). They will use the meeting bot, [http://meetbot.debian.net/Manual.html instructions can be found here]. This bot will automatically generate minutes, based on our interactions with it during the meeting.

Build Infrastructure/Community Builder

2010-10-15T07:55:05Z

Lamikr:

The Community OBS is taking shape.

The current version co-exists with the Maemo.org OBS and targets:
* MeeGo:1.0:Core : Latest Release

The plan is to add:
* MeeGo:Current:Core : Always points to the latest release snapshot
* MeeGo:1.0.80.1.20100514.1:Core : each weekly snapshot. See [[MeeGo_Release_Creation#Weekly_Builds_and_Build_Numbers|the release guidelines]] for an explanation of the numbering.

The deployment supports home:<user> based building only at the moment.
