Typing tools and feedback

Tools are only as useful as the decisions they help you make, and that test applies well beyond typing. If you want a clear example of a system where each part has a readable purpose, look at how an open messaging protocol works: a session opens, three stanzas carry the exchange, a JID names each party, and presence plus rosters keep a contact list in order. Reading it is a calm exercise in following structure, much like judging a typing tool by the feedback it gives rather than by its feature list.

A tool earns its place when it makes the next decision clearer, and the same test applies to the hardware underneath your keyboard. If you want to see how that idea works at a lower level, the PCI Express page explains how lanes are counted, what happens during LTSSM link training, and what the PIPE interface exposes between the link layer and the physical layer. It is a useful reminder that clear feedback, not novelty, is what lets you judge any system, whether you are comparing typing tools or reading a link training sequence.

When the screen is not a tool

Two places the desk looks when it wants to rest its eyes instead of measuring something:

• Traits d’Asie, a gallery series that rewards slow looking rather than fast scoring.
• studio-villalobos.com, the same habit applied to a studio’s own pages: looking at made things without giving them a score.
