Gerald,
I am pretty sure this got to you from Trent but here again just in case and a copy for the list

Re: RE: [OLPC-AU] Hidden SSID and Proxy settings

Yes, this is correct.

More recent OS builds have Browse and Firefox pick up their settings
from the GNOME settings instead of needing to go to about:config. To
do this, go to System -> Preferences -> Network Proxy.

re: harvesting energy

If we're talking about kids powering their own devices, I think the
way to go is to turn "work" into play. The merry go round/hard bar
swing would fit in this category.

So basically, let's look at activities where energy exerted is ambient
anyway? What I mean is that the energy is being used up by the kids
anyway, so why not tap into those. An example is to give them some
variant of those "dance straps" meant to power cellphones before they
go off to run and play during recess and lunch break.

One way to tap into this would be to create new playground
installation toys which can be used for harvesting energy.

Q: how much abuse can a kinetic energy harvester withstand? A soccer
of basketball has a lot of kinetic and impact energy bouncing around.
I'd imagine that's too much abuse though, and whatever harvesting
mechanism would break from the forces.

Would piezo work there?

I think I remember a concept where a dance floor would have piezo
harvesters and when people dance on the tiles, they light up?

Another problem is battery... how efficient and how much can a battery
really store from these small bursts of energy?

Sorry guys, I can't do math anymore since I got traumatized in
college, so would appreciate it if these were translated into
equation-less layman's terms.

you can read the release notes for the firmware releases between
q2e42 and q2e45 here:
    http://wiki.laptop.org/go/OLPC_Firmware_q2e45
    http://wiki.laptop.org/go/OLPC_Firmware_q2e44
    http://wiki.laptop.org/go/OLPC_Firmware_q2e43

i'm sure the release will run.  but q2e45 in particular contains
a fix for machines hanging during boot (d.l.o #9100) as well
as EC firmware which fixes issues with resuming from suspend from
the touchpad.  you can also see that q2e43 fixed very many bugs --
many of them are related to the selftest diagnostics, but others
could affect OFW's ability to install new releases.

we don't issue new firmware lightly, and of course we recommend
that deployments always use the latest firmware.

Very tricky. The Sugar side won't wandle this situation very well at
all. GNOME can handle it.

Under Sugar

 - You may be able to set the proxy setting with a pac file. Pia Waugh
reported once that it worked with 8.2.1, but I don't think she
documented it.

 - Hidden SSIDs are not handled well at all by Sugar's network neighbourhood.

If this is a newer image, one based on F11 then you should be able to
use nmcli to connect.  Take a look at this page.

Hope that helps. My grandma would still hack it in 2 seconds though
