#Corpowid and #Skynet Technologies Will Get You Sued
The market is flooded with so many accessibility overlays that it’s impossible to keep up. I’ve written about the biggest players (plus some also-rans) and provided enough technical details that most readers should know how to quickly evaluate their false claims and poor technology. Never mind their ethical failures as…
Creating an Account UI in .NET MAUI
See how to bring a user interface design for an account screen to life in a .NET MAUI application. How many times a month do you create a new account? Probably more often than you remember. And while it may seem like a simple process, that first interaction can shape a user’s perception of the entire app. As deve…

Shin honkaku

Traditional Web Development is Dead…(and Honestly? Good Riddance.)
AI isn't killing web development—it’s killing the boring parts. The real winners won't be the people who can memorize another framework. They'll be the builders who can spot opportunities, solve business problems, and launch products that once required entire teams. The age of the one-person software company has arrive…
AI Crash Course: WebMCP
WebMCP is a proposed web standard that would provide AI agents with a sort of mental model of a web app’s capabilities via a browser API, saving time and tokens. One of the biggest things we’ve learned about AI is that its strengths aren’t necessarily related to what it can do “out of the box,&r…

There are no "rogue" AI agents [link]
I've read so many posts in the last few months about AI agents going "rogue" and this post does a good job of calling absolute bullshit on the language being used by media outlets (and the tech companies themselves). AI cannot think for itself, nor can it take independent actions. But anthropomorphizing language sugges…

A Trump team wants to automate U.S. Web Design System accessibility testing. Experts are worried. [link]
This is gut wrenching. This is another example of cost cutting exercises that affect minorities.

Most accessibility testing is evaluating how a real…

Redesign: fonts, alignment and nav [blog]
As I continue occasionally tinker on the redesign I've started (and often think "what's the point, current design is fine"), I wanted to share some of the problems I've run in to. Problems mostly for me because I'm not a designer, and I don't have the wiring to know what works.
