Traffic Modeling Using Machine Learning
When I explain the difference between lab (aka synthetic) and field data to people, one of the things I mention is that the lab allows for testing under repeatable, controlled conditions. Each test run offers an apples-to-apples comparison with previous tests, and results are available almost immedi

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.

How on Earth did Immortals: Fenyx Rising not become a total smash when released? It's fantastic! I realise it was overshadowed by Breath of The Wild, but it's like the Arcade Version of BoTW, with great humour and exploding with Greek mythology. Fave game of the moment, for sure.
