i was not talking about C/C++ suggestions. i fully understand that not everybody is able or willing (e.g. because of time constraints) to learn a programming language for the implementation of things like Pd. > The only suggestions I can give are the obvious ones: > - fix the bugs > - design things with an eye on optimization and scalability. these are not the kind of suggestions i was trying to get. imo, they do not solve any problem, just put the load on those that were able or willing to do learn how to fix things on the code level. these are demands. > I simply guess that in some cases, an implementation that is O(n^2) is > chosen just because it is the easiest one, where a O(nlogn) is possible. hmm. it's entirely "possible" that you do learn to code C and implement something in O(nlogn) or O(1). i guess it is just easier to not. > BUT, that does not account for crashes.

Those are bugs, oversights, it is not a matter of allowing to > go beyound limits. no it's way simpler: Pd could just allow you to have a a single [osc~] object and a single [dac~] object. no need to write buggy code to dynamically create objects. simple to maintain. harder to create bugs. boring to use. allowing the user to go "beyond limits" usually involves more sophisticated code: easier to make errors, easier to create bugs. > And wherever a physical, numerical, well-defined limit still exists, > which is unavoidable, it MUST be documented. indeed. the Pdolice will get 'em sooner or later. >> in many it does the latter (which >> is the strength of Pd, i believe). > > Of course it does.
