STL or Qt containers?
...ture, if need be.
The same is true of doubly linked lists, which could use XOr linking to drastically reduce space used. Again, this is impossible with Qt, due to it's requirements for growth and COW.
COW can indeed make something lighter, but so can Intrusive Containers, such as supported by boost,...

Why is a boolean 1 byte and not 1 bit of size?
... Not sure I would agree that bitwise operations are slow. ands, nots, xors etc are very fast. It is typically the implementation of the bitwise operations that are slow. At the machine level they are quite fast. Branching... now that is slow.

How to choose an AES encryption mode (CBC ECB CTR OCB CFB)?
...milarly to stream ciphers generally, the generated pseudo random stream is XORed with the plaintext to generate the ciphertext. As you can use as many bits of the random stream as you like you don't need padding at all. Disadvantage of this simplicity is that the encryption is completely malleable, ...
Relational table naming convention [closed]

That's right. Either user_product_description xor product_description will be correct, based on the above. It is not to differentiate it from other xxxx_descriptions, but it is to give the name a sense of where it belongs, the prefix being the parent table.
