Ooh, yay, I got another one of those AWS Certification thingies!
Looks like I know enough about AWS AI to get a little hexagon 🎉
(Or I'm good at multiple choice exams, either one is one of my key skills anyway 🤘🏻)
Good to collect since it's been a while since I was Microsoft AI MVP backintheday!

After 25 years building sites for global brands, I kept seeing the same pattern appear. A team ships new features, users quietly begin to struggle, and only later do the bug reports start trickling in. Someone finally checks the metrics, panic spreads, and feature development is put on hold so the t

Exploring Large HTML Documents On The Web
Most HTML documents are relatively small, providing a starting point for other resources on the page to load. But why do some websites load several megabytes of HTML code? Usually it's not that there's a lot of content on the page, but rather that other types of resources are embedded within the do

Improve TTFB and UX with HTTP streaming
If you have a statically generated website hosted on a CDN, it’s probably very fast (unless you add too much client-side JavaScript). However, for dynamically generated pages that load content from a database, one of the most overlooked ways to speed up the perceived page load speed is HTTP streami

HTTP has a new method: QUERY. Tl;dr: GET with a body.

The HTTP QUERY Method
This specification defines the QUERY method for HTTP. A QUERY requests that the request target process the enclosed content in a safe and idempotent manner and then respond with the result of that processing. This is similar to POST requests but can be automatically repeated or restarted without concern for partial state changes.
