more like HTML + Javascript. I would have to vote hype though. the guy is selling books on the subjects. not to say the ideas are not interesting. DE appears to me to be a solution in search of a problem. the idea that you would be better off, taking less time and lines of code, getting a diff of the last state of a dialog and sending that to a window manager instead of using event programming where the wm decides what needs to be updated seems like fanciful hype. though I will have to try it to find out. with todays tools and hardware, optimizations from the last century often are no longer cost effective. not every idea is a simplification though, nor are good ideas always easy to grasp or put into practice. the other idea from the same guy in the profiling thread about halting a program at random and looking at the call stack to get a sense of where the program is cpu bound is at best surprising if it has any merit. that is after all what a profiler does. again, an optimization technique usually for larger or cpu bound programs. not something you really need to worry about at the start of a project. the ROI thread has some good advice. to program well you have to program often to get and keep the experience. reading about it almost doesn't count. > > [1]http://programmers.stackexchange.com/questions/35615/what-programming... > [2]http://programmers.stackexchange.com/questions/35615/what-programming... > [3]http://stackoverflow.com/questions/375913/what-can-i-use-to-profile-c... -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
