Hi Tony,

I can respond the more technical aspects. The node service provides the
same API when running locally as it does when acting as a server. This
is so that clients can interact with the Sugar Network even when
completely disconnected. When a node is acting as server, it will
synchronize content resources with nodes acting as clients. Each client
node has a resource cache of limited size. For example, clients may
choose to 'keep' a Sugar activity for using offline. Aleksey tweaked the
node for performance under low memory and disk space conditions (even on
XO1).

The full set of content resources resides in the node acting as server.
This is the only difference. Server nodes have been designed to sync
with each other. Currently there is a node server running on
node.sugarlabs.org, with a front-end running at
http://network.sugarlabs.org/ . This node is what Laura calls the `main
node`. It is running exactly the same software as we have on each XO,
and currently provides service for thousands of XOs. We haven't worked
directly in schools to deploy local server nodes, but conceivably, we could.

Regards,
Sebastian

Hi, Laura

Hi Tony!

Sorry about my confusing  message with the digest title.

No problem :D

I tried the Sugar network several years ago but decided that it
was not usable because it is dependent on internet access. Is that
still the case?

I'll rescue the text from the original thread:

"The node service runs locally on each machine. Thus, the node would 
have to be included in the Sugar distribution. The node offers an API 
for accessing/interaction with Sugar Network resources."


Basically this means that each machine could become a server for a 
local Sugar Network node. Still, some work would have to be done to 
achieve synchronization with the main node.


That said, the last production version was made for Sugar 0.94. There 
would be important work to be done if you want it to run with a newer 
version.


Regards and blessings,

laura V

Hi, Dave

The 'normal mail': tony_ander...@usa.net is rejected by gmail per some 
security check installed in January of this year. Sending emails from 
t...@olenepal.org works because it is a gmail account. I guess I am 
going to have to register for the lists a second time with the other 
olenepal email address. Sigh.

I agree, there are a lot of lists for a (nowadays) small community. I

I just forget to change the subject. Unfortunately, I am not

Changing the email you register on the lists takes only a few minutes, 
so sign up a new email and sign out an old one.


What's wrong with your 'normal' email?
