Re: Various questions ideas: Maemo porting, package management...

Hi Florent,

please send text-only E-Mail to this list.

 - how hard will it be possible to port maemo apps to OpenMoko (if possible)?

This question is two-fold -- it has a build level and an UI level.
Build level: You would need to change the Maemo specific application and widget 
classes to OpenMoko specific application and widget classes. 
UI level: You would need to change the layout of your application from 800x480 
landscape to 480x640 portrait.


 - what about package management? apt-get like mecanism? Do you
 consider using mkezx ? An official binary repository?... 

for phase 1 we will use ipkg. For phase 2 we either would like to see an sqlite 
backend in ipkg (because the default one is really slow) or something written 
from scratch. dpkg/apt is very heavy -- I'm not sure whether we can strip it 
down to be feasible on a smartphone.

 - will the AP's filesystem be read-write ?

Yes, the filesystem will be jffs2.

 - already thought of using handsignature for biometric
 identification? I don't know if there are any free software
 available, i saw a prototype last year on a pda, and it works very
 well. PIN codes are old-fashioned ;) 

No plans yet, sounds fascinating!

 - although a lot of people didn't realize it, apple's iPhone killer
 feature is really the multitouch screen, which IMHO is the key
 component to all these physical-model-based interface effects and
 novel input types; is it certain that the first neo can't have such a screen?

Yes. The hardware of the Neo1973 is unitouch.

 - about accelerometer questions, i saw a cellphone videogame that
 used the phone camera to detect movement, rotation How hard
 would it be to add a standard camera on the neo (1 MP max)? In terms
 of price and technical feasability? I'm not sure it's more expensive
 than a full-features accelerometer, is it? 

Begin a software guy, I can't comment on that. I would imagine it is very 
costly and time-consuming to do hardware changes to a basically finished 
product.

 - i really think a universal infrared remote feature would be a
 killer app (with integration of tv programs); domotics is a great
 area, but is still very expensive; what about porting X10 control
 apps to the neo? :)

Might make not much sense without an IR port or would it? ;)

  There are tons of great apps feasible : perfect
 waker, playing music, lighting lights gradually on etc... 
 - i don't get how a 2.5 G GSM is not EDGE: i thought 2.5 G was
 EDGE... Could please anybody clarify that?

The G terms are somewhat fuzzy. To my knowledge, 2.5G is GPRS and EDGE is 
generally classified as 2.75G technology.

 - i'd like to get an opinion of somebody who actually owns (or sam)
 a neo about the lcd screen. Sooo small, and such a huge
 resolution... Please let us dream :) Is suitable for text reading? 

Sorry, I didn't have a chance to open a PDF yet :/

 - could the neo's usb port be used for usb gadgets? The more
 important would be mechanical input devices ( mini keyboards )
 - already considered an usb multi I/O companion device? Something
 like 
 http://www.pcinpact.com/actu/news/34516-replicateur-port-USB.htm
 (sorry, it's in french) This thing features a VGA/DVI connectivity,
 ethernet, ... If the neo had a small sized extension device,
 allowing external vga connectivity, it would be awesome... And serve as a 
 dock station.

The Neo's USB port is switchable host/gadget, however host is unpowered, so you 
need a battery-powered hub.

 Anyway, openmoko is a great promising project, i'm waiting for it's
 availability ! I hope there will be enough devices for us to buy
 when it's ready for prime time... 

:)

The fact is, mkezx does use dpkg/apt, and it's pretty effective (on my A780) !

As suggested on openmoko wiki:
- minor unexpensive hardware changes may be possible and are open to
suggestions; an infrared led would certainly fit into this category,
no?
- there are hacks allowing to use the jack output to send IR signals,
so a small cheap adapter could provide IR connectivity


The Neo's USB port is switchable host/gadget, however host is unpowered, so you 
need a battery-powered hub.


Hum, does a keyboard need to be powered?

I didn't find any self powered keyboard on google, but a lot of
bluetooth / IR battery powered keyboards

A battery powered foldable keyboard would be awesome:

But it seems that only bluetooth devices are worth it (if we have no
IR connectivity)

 Almost certainly. At the very least there is a microcontroller or other
 hardware to handle the USB protocol and to do the keyboard scanning.

 Unless someone cleverly makes a self-powered keyboard. Anyone know of one?


All Bluetooth ones.
