A rather geeky/technical weblog, est. 2001, by Bramus
Stephanie Eckles, writing for Smashing Magazine: Cascade layers introduce the new at-rule of @layer. The intent is to help CSS authors be more intentional about ordering the “layers” of CSS rules as a new method of cascade management. Getting Started With CSS Cascade Layers → If you’re looking for the quick version on Cascade Layers, …
The author of the Have I Been Pwnd website got a nasty surprise: an AU $5,000 bill from Azure (that eventually racked up to $11,000). The culprit: a sudden spike of outgoing bandwidth due to a file no longer being cached properly. I guess I’m looking at this a bit like the last time I …
Nixery is a Docker-compatible container registry that is capable of transparently building and serving container images using Nix. Images are built on-demand based on the image name. For example: docker pull http://nixery.dev/shell/git/htop The command above will give you an image with an interactive Shell, that also has git and htop installed. Keep adding more path …
In CSS, Specificity is expressed as a triad/triple (A,B,C). An example value would be (1,1,2). To compare specificity — i.e. to see which value has a higher specificity — you need to compare each component of the triple until you find a difference: function compareSpecificity(x, y) { // x and y being arrays such as …

Interesting talk from “Chromium University 2020”, digging into Chrome’s Rendering Pipeline. A tour of the internals of Chromium’s rendering architecture, tracing the steps in the pipeline from web content to display pixels. Concretizes high-level concepts with pointers to important classes and data structures in the codebase While the main concepts — such as a Main …
These Scrolling Tickers by Fabrizio Calderan are quite nice. By calculating the rendered width (via JS, passed to CSS using a Custom Property) and taking that into account to calculate the animation-duration he’s able to synchronise their speeds. What I like most though is how the repetition of the ticker’s content is achieved. Where I’ve …
There’s a pretty nasty exploit in Safari 15, where sites/tabs that interact with an IndexedDB database leak that name to other tabs. In Safari 15 on macOS, and in all browsers on iOS and iPadOS 15, the IndexedDB API is violating the same-origin policy. Every time a website interacts with a database, a new (empty) …
