• Is it good practice to generally make heavyweight classes non-copyable?

  - by Emile Cormier

  I have a Shape class containing potentially many vertices, and I was contemplating making copy-constructor/copy-assignment private to prevent accidental needless copying of my heavyweight class (for example, passing by value instead of by reference). To make a copy of Shape, one would have to deliberately call a "clone" or "duplicate" method. Is this good practice? I wonder why STL containers don't use this approach, as I rarely want to pass them by value.

• Where can I find a good tutorial for py2exe?

  - by Manzabar

  Can somebody point me at a good tutorial for py2exe? I've read over the official tutorial but it is rather light on details, compared to all the options one can use when building an executable out of a python script. For the record, my python script uses Python 2.5.2, wxPython/wxWidgets 2.8 and MySQLdb 1.2.2; so if you have specific tips for py2exe with those packages that would be much appreciated (and yes, I've seen the Py2EXE and wxPython page).
