[Server-devel] Internet Filtering for OLPC school server

Wed Apr 9 11:34:01 EDT 2008
Our company provides kidsnet parental controls (www.kidsnet.com) and we wish
to donate the URL filter database to OLPC to help keep kids away from web
sites that may be detrimental to their development (we believe it is a
better list than SmoothGuardian, Corporate Guardian, URLBlacklist.com and
others).
Does anyone on this list have the contact info for who we should speak with?
Thanks

Hello people!
This is my first contribution to this mailing-list, and I need some
orientation about a proposal that I did to OLPC through the GSOC.
My proposal is implement a method to publication of the objects saved in the
Journal to School Server, and build a web interface, witch become possible
the teachers and parents interactions with the productions of the children.
If you want see my proposal I can send it.
So, I still looking for something that can be a guideline to make this new
Journal resource, I know that is possible update the XO through the web, but
I didn't find the API that make this work.
I only need some indication, a start point to learn about the transfers
between XO and XS, somebody can help me?
Thanks for you attention, and sorry about my poor english.

What do you mean by update the XO through the web? You mean
http://wiki.laptop.org/go/Olpc-update ?

Well, I'm afraid that as of today there is no backup of the journal to the
school server. Or is there?
There was some talk about the xos to initiate backup of their journals when
they got in reach of the school server, taking some precautions to not
overflood the network, the server nor the XO.
The server would have the ability to interpret the metadata and display to
the user the contents of the backed up journal. That software would be able
to perform full text search on part of the text related to entries.
The part that is closer to your proposal is the possibility for kids to
consult the public part of their colleagues' journals.
Ideally, the transfer of entries to the school server would happen
transparently to the user, although perhaps we should add an option to
initiate a single transfer in order to publish an entry without having to
wait for the backup to finish.
Would like to know if this is anywhere close to what other people had in
mind?
Thanks,
Tomeu

Hi!
Could you please copy it to wiki.laptop.org?
Yep! I did it. http://wiki.laptop.org/go/AMADIS
What do you mean by update the XO through the web? You mean
> http://wiki.laptop.org/go/Olpc-update ?
>
Yep again. I don't know if this have any relation with file transfer between
xo and server.
But the focus of my question is don't repeat any existent work. However, if
this is possible or not, only you can say me.
I know about the network problems in the field, in the last year when many
kids, at Porto Alegre trial school, tried to connect with the internet, few
succeeded.
Because of this, I saw that the Journal publication, in the proposal,
couldn't be automatic. Thus can be a problem or hurt the OLPC concepts about
backup, then you can talk to me, and lead me to maintain the means clear.
How Tomeu saw, If somebody is thinking in something closer with this, I
still open to discussion, this is very important to me.
Thanks for your attention.

Yesterday we had a mini-sprint with argentinian pythonistas and we
discussed Alecu's CDPedia which is a Python toolchain that does are good
job of cutting a slice of wikipedia and cutting off the least interesting
parts to make it fit. His project is here
http://code.google.com/p/cdpedia/
and it would be great if Alecu could explain a bit more what it does
-- I am sure I didn't do it any justice above ;-) So - Alecu, meet the
list, list, say hi to Alecu ;-) I would love to see this progress -- we
definitely need something like this to assist the localization teams to
build a good content package for the XS. Are there related projects? I
thought I had seen one but I cannot find anything now, so it was perhaps
discussion about desired functionality?
cheers,
martin

The XS guide would be extremely useful. I am concerned about creating a
guide for it when it is still under rapid development. Please make sure
you are in close contact w/ Martin Langhoff so you don't have to
document a feature or bug that may disappear in a week or two.

That's gorgeous! I didn't know Simple English wikipedia existed -
thanks for the pointer. Sad that I can only see 'Simple English' --
was hoping for a other major languages to have their simple version
too.
OLPC deployments want a slice of wikipedia in the local language
(though they might be interested in 'simple' versions of other
languages). The CDPedia script can slice and dice any language you ask
it to.

I agree 200% with Bryan - at the moment we have an XS build that is
moving quickly (or rather, that is starting to move quickly ;-) ). It
is hard to document such a moving target, specially for beginners.
The path I think Bryan is taking is very smart for the current
situation - aim for decent Linux know-how, and then give them pointers
to the XS specifics (in the wiki).
As we approach 1.0 it will make more sense to have an XS beginners
guide. Hopefully, it will be an easier job too, as things will stop
moving so much ;-)
cheers,
martin

At the mini-conference, I was told that there were problems achieving
global collaboration by federating the schools' jabber servers. The
schools turn out to be behind NAT, and are not globally routable by IPv4,
and there is not enough bandwidth in the network to tunnel all traffic
through a center node at the Ministry of Education.
I asked about this problem on JDev, a Jabber development list, and got a
reply:

| the XMPP domain of your server must be unique. So you could have xmpp
| domains like:
|
| server001.school.org
| server002.school.org
| ...
| server100.school.org
|
| if you setup SRV records for all this domains you should be fine. In the
| srv record you specify the s2s and c2s ports.
This appears to be a good point. SRV records, generated dynamically,
would seem to solve the routing problem for certain kinds of NAT.
Specifically, it seems that it should work for most kinds of NAT except
Symmetric NAT. With Symmetric NAT, we have no choice but to route all
traffic through some globally routable server.

Brian,
I LOVE your list.
Allone day 1, bullet points 1, 2, and 3, cover so much ground, you could
start companies just taking care of this... ;-)
You are right on the mark with your post.
Most of your questions are really my own. And you came up with some I didn't
think of (but hopefully would have being in your situation).
This looks like a good to do list for folks documenting their
accomplishments. Development is not just about getting some fix / feature
deployed, but enabling the 'customer base' to use it -
with a close look on your 'customer's' capabilities... (and he generally is
just undertrained / underinformed / from a 'different background').
Stefan
(I hope to be contributing to Day 1.3 with some sort of knowledge base once
(spare) hardware starts really moving.)
