    If you don’t have a pH meter or an SO2 test kit: Typically, you can just add 50 ppm (1/4 tsp per 5 gallons) of SO2 at the crush. On the other hand, if there were rotted or blistered clusters mixed in with your grapes, or you run your tests and find that you have a high sugar/low acid/high pH must, then you may want to add as much as 80-100 ppm for this first addition.

  • C++ Core Guidelines: Rules for Smart Pointers

  • How to implement the factory method pattern in C++

    Your Factory is a good example too, but your example does not illustrate who owns the pointer a. If the Factory f owns it, then it probably will be destroyed when f leaves scope, but if f does not own it, it is important for the developer to remember to free that memory or else a memory leak can occur. – David Peterson Mar 2 13 at 19:07

  • C++ Virtual Destructors: How to Avoid Memory Leaks

    For instance, consider a pointer to a base class (such as PayOff) being assigned to a derived class object address via a reference. If the object that the pointer is pointing to is deleted, and the destructor is not set to virtual, then the base class destructor will be called instead of the derived class destructor. This can lead to a memory leak.

  • Nobody Understands C++: Part 6: Are You Still Using Pointers?

    Factory Methods There are times where you cannot avoid using “new” to construct an object, such as with factory methods. There are also times when you want to share data between objects and the only way to do that is with a pointer. In such cases you should use smart pointers and reference counted pointers that can automatically delete an object when it is no longer in use.
