CampSmalltalk London tutorial

> First some context. The beginners tutorial ran on the first day. We had 9 developers with a mixed background in Ruby/Java/C#/PHP etc. We started by going through the excellent ProfStef tutorial which we used as jump off point for frequent asides into the tools and code in Pharo.
>
> Next we gave them a simple exercise. You can download the code by grabbing ConfigurationOfCampSmalltalkLondon from http://www.squeaksource.com/MetacelloRepository.html and executing:
>
> (ConfigurationOfCampSmalltalkLondon project version: '1.0') load.
>
> The aim was to put into practice some of the concepts they'd learnt in the ProfStef tutorial - initially focusing on loops. The tutorial grabs live traffic information from the SE of the UK. Initially there is only one entry in the list viewable from their image at: http://localhost:8080/camp-smalltalk-london
>
> The first task was to change the code in CSLTransportInfo>>renderPage: to loop over the results and pass them to a custom renderer. Note we wanted to pass-on the joy of developing a web app in Smalltalk - the liveliness of the environment, code editing in the debugger etc - without first having to learn Seaside. So we hid the Seaside code behind some custom renderers.
>
> The second task was the change the renderer in CSLTransportInfo>>modelRenderer to be a CSLListItemRenderer. The task here was to notice the signature of the addItem method had changed and use the inspector and the browser to discover the relevant accessors on the result items.
>
> Finally they changed the renderer again for a CSLMapRenderer and went through a similar routine to step two, though this time the result of their labours was to transform a boring list into an impressive map - graphically  showing traffic incidents.
>
> Those who were more advanced could then filter the results to look at say only incidents along particular roads etc.
>
> The tutorial session seemed to be well received. I don't know if anyone out there is planning to run an introduction to Smalltalk - if so they are more than welcome to use the code.
>
> All feedback gratefully received.

> Hi

> Though it's been a couple of weeks since CampSmalltalk London, I've only just got round to creating a ConfigurationOfCampSmalltalkLondon which can be used to download the beginners tutorial Tim Mackinnon and I created.
