Coffee & Gems

Just read this post from JRuby god Ola Bini which pointed to an older article by Paul Graham . Eloquently as ever, Paul explains his views that more clever guys use superior technology and therefore are likely to succeed in business (i.e. be more successful than the competition). During the years we worked on Viaweb I read a lot of job descriptions. A new competitor seemed to emerge out of the woodwork every month or so. The first thing I would do, after checking to see if they had a live online demo, was look at their job listings. After a couple years of this I could tell which companies to worry about and which not to. The more of an IT flavor the job descriptions had, the less dangerous the company was.

We simply had no reason to create another object for transporting data. If we want to pass a model object to the business delegate we simply pass this model. I we want to pass some very simple set of variables (say, a string and an integer) we simply add that into the event. No n
