I have been watching the commits go by on Stanford’s Class2Go<\/a> software and really liked the high level of activity by Sef, Jason, and the rest of the team. It is fun to watch a project like this even when they are a small team and sprinting forward and don’t have much time to build a community. Starting from day one in the open is simply great – we can learn so much even if all we do is watch.<\/p>\n

Of course I tweeted<\/a> about how cool it was to watch and threatened to write some code and contribute it. Then Jane Manning<\/a> suggested via Twitter that I actually try to add IMS Learning Tools Interoperability (LTI)<\/a> to it.<\/p>\n

I didn’t teach SI502 until 1PM today and I had a full cup of coffee so I figured I would give it a try. About 90 minutes later I have Class2Go running on my laptop. <\/p>\n

Along the way I figured out that Class2Go already<\/b> has IMS LTI built in as its method to integrate Piazza<\/a> discussion forum. But I still figure I can hack in a nice “External Tool” capability into Class2Go and do LTI 1.1 grade integration since I bet they don’t have that yet. Here are my results so far:<\/p>\n

The following are my notes as I went along that adjust what the Stanford documentation told me to do. My step numbers follow their step numbers it is probably best to scroll through their documentation and my steps at the same time.<\/p>\n

Update October 15, 2012:<\/b> I submitted improvements to the Stanford instructions and they are now updated to reflect everything I say below. So ignore my notes below and just look at the new-and-improved Stanford instructions – they should work.<\/p>\n

\r\n\r\nStanford's Instructions:\r\nhttps:\/\/github.com\/Stanford-Online\/class2go\/blob\/master\/README_SETUP.md<\/a>\r\n\r\nChuck's Notes:  Update:<\/b> My notes below have now been integrated into the above instructions.\r\n\r\n1. Upgrade Xcode to 4.5.1 via App Store\r\n\r\n2. Within XCode, add the command line tools: \r\nPreferences -> Downloads<\/b> -> \"Command Line Tools\" Install button\r\n(tiny typo in their instructions)\r\n\r\n3.  Homebrew URL in their instructions - gives 404\r\n\r\nSo I went here:   http:\/\/mxcl.github.com\/homebrew\/\r\n\r\nAnd did this:\r\n\r\nruby -e \"$(curl -fsSkL raw.github.com\/mxcl\/homebrew\/go)\"\r\n\r\nAfterwards I ran :\r\n\r\nbrew doctor\r\n\r\n4. I skipped this step did not install Python - I already had 2.7.1 and \r\nhoped I would be OK.\r\n\r\n5. I already had mysql so I skipped this step\r\n\r\n6. sudo easy_install pip\r\n\r\n7. sudo pip install virtualenv\r\n\r\n8. Here is what I saw\r\n\r\ncsev$ pwd\r\n\/Users\/csev\/dev\/class2go\r\n\r\nvirtualenv sophi-venv --no-site-packages  \r\nNew python executable in sophi-venv\/bin\/python\r\nInstalling setuptools............done.\r\nInstalling pip...............done.\r\n\r\n9.
