Re: Installing packages onto /media/...

[Martin Grimme]

Hi,

another and maybe easier way is to boot from SD card. As a bonus,
you'll get faster booting with a fast SD card.

Search www.internettablettalk.com or the wiki on maemo.org for
instructions on how to boot from SD card.

Martin

John,

In Switzerland, and from what I know in most on the west Europe, 2G/3G 
handsets are the standard. The GSM / 3G switching is completely 
transparent to the user, even on the active call.

didn't look into it myself but I think if you find a way to bolt-on
unionFS (http://www.filesystems.org/project-unionfs.html) you can
achieve that - have a "base" system on built-in flash and the rest on SD
or whatever else you feel like. EeePC does that out-of-the box, and I
think it's a darn good idea - having stable OS underneath and having
easy roll-back plan (just wipe FS stacked on top of "base"). Good luck

Installing packages onto /media/...

[Peter Flynn]

I have a nicely-running N800, but the apps I use are taking up most of 
the internal space. I want to add a couple of big ones (TeX is one) and 
I have plenty of space on SD cards. Is there a command for package 
installation that says, in effect, "install this all in /media/foo/bar 
and symlink it back to where you would normally have installed it"? Or 
some other way? I guess if I knew how to view the inside of a package I 
could work out where all the big stuff is expecting to go, and create 
symlinks in those places to the SD cards...or would that make the 
installer spit blood when it finds that symlinks exist where it expected 
to create new directories?

Re: Nokia device usage

[John Holmblad]

kenneth,

I have not read the HSDPA spec myself but my assumption is that it is 
"all packet, all the time"  As the "P" implies in "HSDPA" 

UMTS, as a superset of HSDPA incorporates  various  QOS  and other 
features (roaming, voice connection awareness, etc) that are needed in 
order to properly handle voice traffic as a part of the total packet 
stream on a UMTS network. As I understand it, the key difference between 
voice traffic on a 3g network vs voice traffic on a 4 g network such as 
one based on,  LTE, or  WIMAX  is that on a 4 g network the network core 
is packetized and runs IP (or at least an connectionless packetized core 
with a network protocol that looks like IP) with QOS enhancements for 
the voice packets. On the other hand, on a 3 g network with HSUPA or 
HSDPA, the voice traffic, although it may be statistically multiplexed, 
is not competing for the same bandwidth as the HSUPA/HSDPA packets. 
Perhaps a 3G expert on this list could clarify this somewhat subtle 
point. if not I will dig into the spec myself to figure this out.

I have always (professionally speaking) considered voice as  a 
particular case of data (bits if you will) with specific 
characteristics, i.e. connection oriented, duplex content flow, 
streaming, delay sensitive, and relatively narrow bandwidth (i.e. 
frequency limited) per "conversation"/connection.

My assumption is that most GSM mobile network service providers who are 
evolving to 3G are building HSDPA overlay networks  to first (and 
primarily) convey non-voice data (by my definition, above, not an 
oxymoron)  just as the CDMA based mobile network service providers have 
built EVDO overlays to do the same thing. In other words those GSM 
service providers are not attempting to move their voice traffic to UMTS 
right away.

A key difference  between HSDPA/UMTS on the one hand and EVDO/CDMA on 
the other (in terms of application of the underlying technology)  is 
that, in the U.S. at least the CDMA/EVDO providers (the largest being 
Verizon and Sprint) are not themselves using EVDO to convey voice 
although the end user of EVDO service could certainly do so (e.g. SKYPE 
or arrangement with a SIP trunking provider). They are using EVDO 
service to meet new and growing demand for broadband wireless Internet 
access.

On the other hand mobile service providers who are evolving from GSM to 
3G/UMTS can, if they so choose, start to move their voice traffic over 
to their UMTS infrastructure (equipment and RF) and do so gradually by 
providing their customers with dual mode 2g/3g handsets. Although the 
UMTS standard, supports call handoff from GSM to UMTS, I have to wonder 
how much of that is actually going on right now since the user would 
have a dual mode (GSM + 3G) handset and the network would have to be 
engineered to implement such inter-technology (GSM<=>3G) handoff/roaming.

I've got a 16K x 1 core memory plane from a Collins 8500B computer
here.  However, core memory tends to be very expensive, slow, power
hungry & bulky.  Not sure you want that in your Nokia.  ;-)

Re: Naive question , How I can control where applications are installed ?

[mihai]

Indeed, however you can do a small hack and symlink the /usr/lib (or any other 
BIG directory) to the memory card. I'd recommend to check that boot can still 
be performed.

Happy hacking ...

not really, only thing you can do is run the OS from the mem card.

Re: N8xx ponderings

[John Holmblad]

Fred C,

re your comment

"...with more core memory."

Where can I get some of that?

The long boot time of windows XP, and, for that matter Vista, explains 
why Microsoft is racing to get Windows 7 out the door to "fix" that 
Achilles heel vs Linux. Microsoft are only too aware that today's 10-18 
year olds (the next generation, if you will, of corporate users) will 
prefer what works first/fastest to reconnect them to their connected 
world vs whose name is on the OS.

This reboot lag time problem even extends to Windows Mobile. My 
experience is that when I have to boot my Windows Mobile handset it 
takes over 60 seconds whereas  my Nokia IT takes 30 seconds. Our 16 year 
old who texts beyond belief with an LG Voyager would not give a Windows 
Mobile handset the time of day.

Best Regards,

 

John Holmblad

HSDPA do not result in data only, as HSDPA only builds on UMTS. and UMTS 
carry voice just fine...

Yup, that's practically assured. However, you were also talking about
how it definitely won't have voice; there's been no definitive
statement on that, and the evidence either way is not yet persuasive.

Of course I can be wrong. I just read news from Maemo site:

http://maemo.org/news/internet_tablet_talk/dr-ari_jaaksi_on_maemo_5/


Dr. Ari Jaaksi has just finished his keynote speech over at OSiM, 
revealing a lot of juicy stuff on the future of Maemo. Check out the the 
upcoming Maemo 5 (5th generation) highlights:

 * online anywhere with cellular connectivity over HSPA for 
broadband anywhere
 * powerful computing with TI OMAP3 processor - for better 
performance and better graphics performance
 * photo sharing with hi-def camera - imaging and photo-sharing
 * Nokia is now Gold Sponsor of Linux Foundation, has contributed 
code today for 3G/HSPA cellular (data) connectivity for OMAP3 to Linux 
kernel

 * no news yet on backward compatibility for older devices


 From what I can find on the net, HSPA seem to be an extend of the 3G. 
So it seem logical to me that the next tablet will have 3G radio.
