right-angles Orthogonal: • Unrelated (no relation exists) We use orthogonality to: 1. Remove interactions 2. Reduce coupling Benefits: • Less complexity • Fewer edge cases • Increased stability • B Orthogonality grants simplicity to dismiss as a possibility some behaviors or component interactions within the resulting system.Charley Bay - charleyb123 at gmail dot com The Roles of Symmetry cppcon 2021 Orthogonality allows us to dismiss as a possibility some behaviors or component interactions (without tedious inspection) A BCharley Bay - charleyb123 at gmail dot com The Roles of Symmetry

that yields a certain degree of trust. A permissioned blockchain provides a way to secure the interactions among a group of entities that have a common goal but which may not fully trust each other. By with peers to access the ledger. Ledger-query interactions involve a simple three-step dialogue between an application and a peer; ledger-update interactions are a little more involved, and require two extra Fabric, but don’t worry — what’s most important to understand is the difference in application-peer interactions for ledger-query compared to ledger- update transaction styles. Applications always connect to

We want to reduce the impact of BlenderVR on the blender file (.blend). For instance, all the interactions issued from the plugins (VRPN, OSC ...) don’t have to be defined inside the .blend file, since notion of processor file. It is a Python file associated with the .blend that contains all the interactions required to use the .blend file within BlenderVR. By default (and you should not change it) this each item (the objects as parameter of getItem). Processor Inheritance We commonly use the same interactions on different scenes. For instance, the Head Control Naviga- tion system is useful on most scenes
