This was originally the majority of this post: Start a django project the right way but I’ve decided to put in it’s own post instead.
I’m assuming you’re on OSX. If you’re on Linux most of these steps will be the same. If you’re on Windows… Install VMWare and then install Linux.

Don’t check a pointer before deleting it, just delete it.
// don't do this if ( p ) delete p; // just do this delete p; // ie: this doesn't crash or do anything bad int* p = NULL; delete p; // but you probably need something like this #define NUL_DEL( p ) { delete p; p = NULL; } NUL_DEL(p) |
But seriously, this isn’t the dark ages, you really want to be doing this.
std::shared_ptr<int> p; ... p.reset(); // no need to set to NULL (or rather null_ptr) |

Part of my Why is simple hard? series.
Like most people with taste, I despise Hungarian notation. But, at the end of the day it really is only a style issue and easy enough to fix with a search & replace.
Controlling complexity is the essence of computer programming.

This has been bugging me for years, and it’s getting worse. In some type of ironic paradox, it seems like the worst programmers are (in some ways) the best programmers.
