Boy Scout Rule

So I was happily coding the other day and ran across some code new to me. Mind you we used to have something like 8 developers on our team over the last couple of years and now we have 3. So naturally there are parts of the codebase I have not seen before. Anyway, the code looked like this:



I saw the todos commented above each method and thought I could tidy these up a bit. It wouldn't take long. So here is what I ended up with:



It took me five minutes and was a nice confidence booster to keep me going on my regular task at hand. So the lesson for the day is follow the "boy scout rule" which is nicely described here by Uncle Bob Martin: http://www.informit.com/articles/article.aspx?p=1235624&seqNum=6

Setting up Sinatra and DataMapper on Windows

I use a MacBook Pro for work and pleasure on a day-to-day basis. Recently, I was asked to teach web students at a local high school. These students know html/graphics/flash/etc. The advanced students were ready for some server-side programming and database integration. I wanted the students to be able to get up and going quickly (for motivation reasons) and to create useful apps (using a database). I felt Sinatra to be a great fit for this. I created a Sinatra app for my uncle and his business. It was a joy to work with it and I was able to deploy quickly using Heroku.
My experience of using Sinatra on my Mac was straightforward. Like most things using Ruby and Mac: it just worked. However, I found out the students at the high school use MS Windows. Fortunately, I have a Windows XP virtual machine running in VMWare so I could prepare that way. I used to teach computer science and web development at Spokane Community College and am aware of teaching Ruby in a Windows lab environment. …

Improving Traditional Software Development Education

I read Corey Haines post about his idea for software development school. I thought I'd jot down some of my experiences while I taught software development.
I taught community college computer science and web development for 7 years. In the summers I worked as a contractor to gain 'real-world' experience. This allowed me to teach what I learned over the summers in the classroom. Towards the last couple of years of teaching I worked at nights while I was teaching because I enjoyed it so much.
To me I saw a lot of teachers take the easy road: picking canned curriculum that laid out non-practical material, have a work study student grade for them, etc. while they go home early. This was frustrating to watch and be around!! I picked industry books (PragProg, Addison-Wesley, etc.) and used them for reference while I created custom curriculum every quarter because of technology changes. I did not picked canned textbooks. They drove me nuts being out of date and out of touch…
