Beauty is in the eye of the persona

A trader looks at his setup: five screens, a TV and a squawk box, every inch of it orange on black. His eyes pop out and his heart is trying to leave his suit. Next to him, a minimalist designer wonders who on earth designed it. Both are right. There's no universal good user experience, only good user experience for this person's job. (I got migraines looking at trader screens. Traders loved them.)

TL;DR

Matt thinks out loud here about technology, mostly how teams decide what to build, fix and protect.

The first series argues that security gets better fastest when the teams that each hold part of the answer share it earlier. Part 2 says most critical findings aren't: seven questions tell you which, and the answers live with other teams. Clay first, chisel later is about roughing out the whole thing before polishing the parts.

Every piece says how much AI helped, and the site changes in the open. The discussion happens on LinkedIn.
