There is a special form for boolean formulas called "Conjunctive Normal Form" (CNF). A problem in this form consists of clauses connected with and operators, where each clause only contains variables connected with or operators. The variables can appear negated, but only variables can be directly negated, something like !(a && b) is not allowed. An example boolean formula in CNF form is:
Since every person is different, there’s no one best ergonomic keyboard layout. The standard QWERTY layout is what most people are used to. The Dvorak, Colemak and Workman layouts rearrange the board to put the more commonly used letters closer to the home-key position. All three are intended to minimize your finger movements.

One especially heavy piece of our backend architecture that made this possible was the inventory service. The term “inventory” here is a bit overloaded given just how many of the game’s systems use it. In Towerborne nearly every piece of persistent player data is part of the inventory. Beyond traditional inventory items like weapons and gear, the inventory also includes stats, quest state, conversation history, achievement progress, and more.
