Reading the coding standards at a company I recently joined revealed to me the issue with default label within the switch statement and why it’s prohibitted when its being used to enumerate through an enum. default label is convenient to handle any edge cases and it’s often used to handle errors. However, when working with enums, it is often the case that the prpogrammer intends to handle all possible values in the enum. To catch this mishap, programmers would enable -Wswitch or -Werror=switch to their compiler. For instance, let’s suppose I have an enum named Suit to represent the different...

I noticed that the neocities community love using protonmail and some even share their public key to enable full encryption communication. What makes protonmail special is the focus on privacy and security. All emails sent between Proton Mail users are end to end encrypted meaning not even Proton can have access to the messages.

This does not mean the encryption utilized by Gmail and Outlook are inadequate. The vast majority of...
