Presentation i did at Ottawa Linux symposium about various application toolkits for Linux based embedded devices and how they stack up against each other.

1. Choosing an application framework
for
Mobile Linux Devices

2. TM
The story of the Simputer

3. Drawing was simple

4. Open Alchemy
http://openalchemy.org

5. Times be changing

6. ARM Twisting
(This is good thing!)

7. Summer of X86
Winter of XScale

8. Embedded Graphics

9. OpenGL, OpenVG

10. Changing user expectations

11. Getting X off the hardware
All hail Keith Packard!

12. The Contenders

13. Gnome/ Gtk

14. Kde/Qt

15. Enlightenment/ E

16. Clutter/ Tidy

17. Android

18. Utopian application framework

19. Timeline and animation support

20. Simple rotate, alpha and transition

21. Experiments with Cairo
CPU goes Waaaah!

22. Hardware wants to be *used*
Under assumption than marvin hasn't been created yet!

23. Re­write our birth right:
This time we use hardware

24. Benchmarking frame rate

25. Tesselated texture on Intel Mobile

26. Simple polygon drawing

27. Hardware support Rendering to
Name Animation api (Opengl/gles) Ofscreen Pixmap
Gtk/Gnome No No No
Qt/Kde Yes Opengl Yes
EFL/E Yes Opengl Yes
Clutter/ Tidy Yes Opengl/ gles Yes
Android Yes Opengles No Idea!

28. Multi language bindings

29. Name Languages
Gtk/Gnome C,C++,python, java, c#
QT/KDE C++,Python, Java
Clutter/Tidy C, Python
EFL/E C,Python (C#)
Android Java

30. Email and HTML libraries

31. Name Email Browser
Gtk/Gnome Camel GtkMozembed,
GtkWebkit
Kde/Qt Akonadi, Kmail Khtml, QtWebKit
Clutter/ Tidy Clutter Webkit
EFL/ E
Android Webkit

32. Inter Process Communication

33. Name Platform
Dbus Gnome, QT, EFL, Clutter
Android.os Android
(Its called Ibinder amazingly,
no relation to the Iphone i swear)

34. Possible Scenarios

35. Scenario 1

36. Hardware:
GPU/ FPU
GLES support
Supported Driver
Eg: Freescale I.MX31
Omap 2430, 3430

37. Best Bet: Clutter, Gtk

38. Hardware:
GPU/ FPU
GL2.0 support
Supported Driver
Eg: Menlow
Amd mobile processor

39. Best Bet: QT, Clutter, EFL, Gtk
(In that order)

40. Hardware:
No GPU/ FPU
Eg: Xscale

41. Best Bet: EFL, Gtk, QT

42. Challenges going forward

43. Multi core architecture:
Do we have a strategy?

44. New Input handling?

45. Predicting next wave of display
technologies
* E­Ink
* Projection

46. Building a linux­based mobile device
has never been easier

47. Building a worthy device continues
to be an exciting journey
