Typically there are just Java and C# courses nowadays... There are two big problems in my eyes: First, the majority of developers don't know the "real" OO and are stuck in their imperative way of thinking (a fate that OO shares with other paradigms like functional programming). When somebody wants to learn OO, he or she will most probably end in one of the mainstream languages, like C#, Java and C++. The problem here is that there is only a vague description and no real definition of the term OO. Second, what (real) OO delivers is mostly not valued in commercial environments. Sure, everybody wants reusable, maintainable and scalable code, but only very few are willing to pay the price for it. In my experience you typically win a contract for the cheapest offer - quality is hard to measure and is most of the time of lower interest and measured in funny units like lines of code or cyclomatic complexity. As software projects are (almost always) complex, it's hard to get the requirements right. When the requirements will be substantiated you can always add time and money to the contract :) Customers typically cannot change the company that is working for them easily - too much time and money already spent (and no guarantee that the next will do better). So for an economical point of view for a software company it's better to be cheap than to be good and accurate. Often it's even better to deliver bad solutions - they will bring more money. To put it in other words: To my experience software development is driven by estimated costs and deadlines. There is a saying: "Time, costs and quality - choose any two of them." But is anybody really willing to drop time or costs? Regards Andreas

Re: [Pharo-project] Updated Download page 1.4

True, but I have had good luck with just dumping the image/changes and vm in a folder and creating my own shell script to run it. One-clicks would be nice, and would probably get us more testing. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] on behalf of Janko MivÅ¡ek [janko.mivsek(a)eranova.si] Sent: Monday, February 27, 2012 12:57 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Updated Download page 1.4 Hi Marcus, An OneClick build would be also very useful to test 1.4 quickly.

this looks really nice. I would really like to see if we cannot include a version so that people can browse change set and other code like that. I'm really happy to see that the work done by alain and ben around treeMorph pays off that well.
