Ideas I can think of: Map, satellite, globe, grid, radio-signal.

A map is probably not easily recognizable at icon size. A satellite
alone misses the point. Globe + satellite + signal + position indicator
is already taken by TangoGPS and probably too complex anyway. 

Just a globe with a crosshair over it (as position indicator) would be
pretty good, I think.

I think he's able to make some invisible text (e.g., white print on
white background) visible by selecting it and concludes that the
"hidden" text is protected by NDA and was not intended to be published.
Of course if he's right he should have contacted you privately instead
of making cryptic remarks on a public list.

An automated confirmation mail, just confirming that the order was
received, would be helpful. After a week I'm not even sure that my order
got through.

I tried to add this to the ticket, but apparently you can only do this
if you have an account and I haven't figured out how to create one.
So I'm posting it here.

I plotted the delay (difference in the timestamps of the last two
Received lines) versus time, and found that the delays were fairly short
(a few minutes) until May 21st. Then there was an outage of about 16 hours,
and after the service resumed on May 22nd, there was a constant, rather
long delay (with a few large spikes):

Good catch. If that's true it's a good argument for ordering from
Pulster or some other distributor in the EU. They have to give you 2
years of warranty.

Yes, fcron is probably the best starting point (judging from the
features - I haven't looked at the code). Not only does it already do
many of the things we would want, the config files have an extensible
syntax - if we need some new option (e.g. for "wake up for this job"),
it can be added.

Looks like most of the people with long delays (me too, btw) subscribed
only recently.

There are 1651 non-digested addresses subscribed to the list. I don't
know the setup of the mail server, but if it tries to deliver to these
addresses serially it is quite likely that it takes 2 hours to go through
the whole list, especially if some of them are unreachable.

So maybe the postmaster should do some tweaking.

But all of these things a user has to be able to do - so if the user's
account is compromised, the intruder can also do these things.

I think there is some value in separating privileges even on a one-user
device, but I don't think "the user" vs. "root" is a useful separation,
because you will end up with a user who is essentially root and can do
everything interesting.
Separating applications may be more appropriate (e.g., the browser may
not need to be able to send SMS), but that needs careful thought.

I think a straight port of cron would be simple but not very useful.
Cron is really designed for computers which run 24/7. 

A cron-like tool for a phone (or any other device which is suspended
most of the time) at least needs the ability to wake up the device in
time for a scheduled job to run and go back to suspend mode after it has
finished. But many jobs usually don't need to run at a fixed time. They
can just run the next time the device is woken up by the user. Or the
next time the device has AC power.

Note that this amount contains the cost of shipping to the US, US
customs, and the margin for the US seller.


[extra costs are more than 60 Euro]


> Pulster say that is able to sell FR at 299 Euro. I think they are magician!

I imagine that Pulster won't import 10-packs from the US. They will
probably order larger quantities directly in China, so instead of paying
for shipping to the US, paying US customs, then shipping to Europe and
paying European customs, they only have to pay for shipping to Europe
and pay European customs. So that makes it quite a bit cheaper already.
And the bigger quantities should help too. Even if they import from the
US, I'm sure they get a much better price for 100 10-packs than we get
for a single 10-pack.

> In every case I think is a good price.

Yep.

To send and receive mail you need IP (well, not really, you could use
UUCP, but all the common protocols for reading and writing mails today
(POP, IMAP, SMTP/Submission, HTTP) need IP). IP doesn't care much about
the lower layers: It works on GSM as well as on UMTS (only slower), just
as it doesn't care whether you've got 4 Mbit token ring or 1000 Gbit
Ethernet. As long as your provider gives you an IP address, it will
work.

As for the lifetime of GSM/GPRS: I have no idea when the telekom
companies will drop GSM. No doubt they will at some time, but since many
PDAs/Smartphones sold today (for example the Palm Centro) still don't
have UMTS, and UMTS coverage is still bad in many regions, it will be
some time. So I'm not worried about the GTA02 not supporting UMTS. The
GTA03 probably won't need it either, but if the GTA04 is still only 2G
it might be the only one when it is released - and that might be the
point where telekom companies could turn off GSM.

I don't have an openmoko yet, so I don't know how the display actually
looks or how slow it is. I also don't know what I will use the
freerunner for once I get it. But I image that the majority of uses
involves text (email, news, ssh) which should really be displayed at 80
chars/line. Probably simple graphics, too (e.g., maps). But I don't
think I'll use it to watch videos or play 3d games - so high video
performance isn't a high priority for me.

My gut feeling is that 640x480 at 2.8" is awfully small (I've
printed a screen-shot of an 80x25 windows (with mutt displaying a
message from this list) at that size - I can read it, but I think
reading longer messages at that font size would be a pain). So I think
the direction openmoko should be going in later models (GTA04?) is
towards a larger display with at least the same resolution (maybe
640x480 at 4.2", or maybe a wider display (800x480?))
