  Presentation:

   Joel Stanley will be giving a talk on the One Laptop per Child
   (OLPC) project:

   OLPC[0], a not for profit group originating from the MIT Media
   Lab[1], have spent the past two years dreaming up, designing and
   developing a sub-US$100 laptop for use by children, to be sold
   exclusively to governments who will provide them to disadvantaged
   children.

   At LCA 2007, Jim Gettys[2], VP of Software at OLPC announced that
   they were giving away a couple of XO[3] laptops, to those who were
   willing to work on them. Joel Stanley was lucky enough to receive
   one, which he will display on Tuesday. He will give some background
   on the OLPC project, and talk about the current status laptop,
   including some of the more interesting technology it employs.

   Joel is 21, in his final year of an Electrical Engineering (Computer
   Systems) and Economics double degree at the Uni of Adelaide. He runs
   ubuntu, edits with vim, and doesn't care if Han shot first.

Trusted Code 2.0

So back in .NET 1.1 days we had a problem running C# code off a remote fileserver - Windows trusts, by default, code on the local machine only. Fortunately there is a work around, which we dubbed The Dilbert Zone.

Moving our product across to .NET 3.0 means changing the security trust on the local machine for this new environment in a similar fashion.

Start the appropriate configurator found at Start|Settings|Control Panel|Administrative Tools|.NET Framework 2.0 Configuration

Navigate to Console Root|.NET Framework 2.0 Configuration|My Computer|Runtime security Policy|Machine|Code groups|All_Code|LocalIntranet_Zone and select Add a Child Code Group.

Create The Dogbert Zone, with condition type = Zone, Zone = Local Intranet, and Permission set = FullTrust. Select Ok a few times and exit out of this user-unfriendly administrative console.

Restart Visual Studio 2005, and voilà - it just works as expected.
