CSS Combinators

A combinator is something that defines the relationship between two or more selectors. There are four different combinators in CSS:
1. Descendant combinator (space)
2. Child combinator (>)
3. Next sibling combinator (+)
4. Subsequent-sibling combinator (~)
A CSS selector can contain more than one selector. Between the selectors, we can include a combinator, to create a more specific selection.

Dans son dernier livre, Anton Jäger, historien des idées politiques, tente de comprendre ce paradoxe : alors qu’il n’a jamais été aussi facile, grâce aux réseaux sociaux, de se mobiliser en masse, les mouvements sociaux ne semblent jamais arracher de vraies conquêtes. Comment la culture politique s’est-elle transformée ? Pourquoi nous sentons-nous aussi impuissants ?

Creators Welcome: Inside the Video Codecs and Media Engines of Intel Arc Graphics - YouTube

What is media? When you watch an mp4 file or your favorite streamer play a game online, how do those images and sounds make their way to your eyes and ears, and what role does compression play? How do codecs work to efficiently encode media files for storage and transmission, and decode them for playback? Finally, how does Intel Arc’s media engine accelerate these processes and empower content creators working with large files and complex, multi-layered media projects? Intel Fellow Tom Petersen talks to Thomas Green, an editor on the Intel Creative team, and engineer Ryan D. Jocoy to answer these questions and talk about the secret sauce that makes Intel Arc a media monster.

Managing EFI Boot Loaders for Linux

Dealing with Secure Boot. In addition to implementing a new boot protocol, UEFI adds a new feature that can improve system security, but that also has the potential to cause a great deal of confusion and trouble: Secure Boot. As the name implies, Secure Boot is intended as a security feature. By its very nature, though, Secure Boot can also make it harder to boot Linux, particularly on commodity PCs that ship with Windows pre-installed. This page provides an overview of what Secure Boot is and how the Linux community is responding to it. Although Secure Boot is developing less rapidly than it was in late 2012, when I first wrote this page, it's still a dynamic area. In other words, things may have changed!
