Hello List<br><br>Just from my (not too recent) experience with the Birmingham deployment:<br>There are two competing interests:<br>- As long as the Board of Education (BoE) receives federal funds under the No Child Left Behind Act they are responsible for providing internet only in a filtered manner (certified, lots of signatures and red tape ...). The Birmingham BoE is *very* broke so they rely on these funds. Effectively this means upstream filtering in the BoE's IT department's realm (this also helps them - gets abused for - demands for additional funding).<br>- To provide a cost effective solution (without lots of additional funding for overhead / BoE infrastructure) the XS could provide a filtering solution of its own and thus provide a daring principal with a way of providing parallel infrastructure just for XO/XS purposes.<br><br>This means as long as the BoE does not agree to a two tiered IT infrastructure (which they in my opinion can't), DansGuardian is not needed. Yet it might be helpfull in increasing acceptance for olpc products in a less messed up environment.<br><br>In previous discussions I understood that olpc did not want get in a place where it could be held responsible for content filtering (with no resources and mandate to manage the servers remotely a very understandable stand). I do think though that olpc can only provide the tools currently available and should not worry too much about whether local admins put them to good use.<br>(And I personally favour Brasil's teachers union's stand to turn filtering off. Life filtered is not life. Encounter the problems, use them for contents of lessons, and get on with reality.)<br><br>just my 2cts (and keep up the great work!)<br>Stefan<br><br>Btw: I just relocated from Alabama to Germany for job reasons and have no personal stakes in the Birmingham deployment (nor any other deployments for that matter).<br><br>> Date: Tue, 7 Oct 2008 20:06:25 +1300<br>> From: martin.langhoff@gmail.com<br>> To: wad@laptop.org<br>> CC: server-devel@lists.laptop.org; greg@laptop.org<br>> Subject: Re: [Server-devel] DanGuardian and XS Plans<br>> <br>> On Tue, Oct 7, 2008 at 4:17 AM, John Watlington <wad@laptop.org> wrote:<br>> > In existing deployments (not trials) content filtering<br>> > is being done upstream in the internet connection.<br>> <br>> Interesting!

And also very clear that we believe that filters are quite leaky<br>> -- meaning that they will have problems with it, and a plan / process<br>> to deal with it. Some local teams may find planning for such<br>> situations hard.<br>> <br>> > Squid has been supported since build 161, long before<br>> > Martin started wholesale improvements.
