What is Object Oriented CSS?

JavaScript can dynamically manipulate the content, structure, and styling of an HTML document through the Document Object Model (DOM). The DOM represents an HTML document as nodes that can be accessed and modified with JavaScript. Common tasks include dynamically creating and adding elements, handling user events like clicks, and updating content by accessing DOM elements by their id or other attributes.

Have you ever needed to get some additional write throughput from MySQL ? If yes, you probably found that setting sync_binlog to 0 (and trx_commit to 2) gives you an extra performance boost. As all such easy optimisation, it comes at a cost. This talk explains how this tuning works, presents its consequences and makes recommendations to avoid them. This will bring us to the details of how MySQL commits transactions and how those are replicated to slaves. Come to this talk to learn how to get the benefit of this tuning the right way and to learn some replication internals.

Pseudoselectors should only be used when other options aren't available. Overall, the document emphasizes writing CSS according to first principles of maintainability, predictability and avoiding premature optimization.

Derrière ce titre putaclic se cache une réalité pour une partie de notre industrie. Les boucles for/while sont des structures itératives proposant le plus bas niveau d'abstraction. Les langages modernes proposent encore de nos jours ces structures car elles ont leur utilité dans quelques cas exceptionnels. Ces 10 dernières années, de nouvelles structures d'itérations sont apparues, proposant un plus haut niveau d'abstraction : donc une meilleure productivité, moins de ligne de code, donc moins de bug potentiels (que nous décrirons). Nous partirons d'exemples de code simple et montrerons leur équivalent via ces nouvelles structures puis observerons les avantages (et inconvénients ?). Les exemples seront en JavaScript mais bien entendu applicable dans d'autres langages (Java, C#, Python, Ruby, C++, Scala, Go, Rust, ...).

The document discusses CSS frameworks and grid-based design. It introduces CSS frameworks as sets of tools and best practices that abstract routine tasks into reusable modules. Grid-based design uses a grid system to organize content spatially on a page in a clear, meaningful way for users. The document examines specific CSS frameworks, Blueprint and 960gs, and discusses advantages and disadvantages of working with grids, including how grids can facilitate creativity but also impose restrictions. It also explores using the 960gs framework with the Drupal CMS.

The JavaScript community is one of the most vibrant and fun groups I've ever been lucky enough to be a part of. Like any vibrant community, sometimes people don't play nicely. In this session, I will discuss what it has been like to be shy *and* be on twitter, mailing lists, and open source. I'll talk about my experiences consulting on massive CSS overhauls, and ways to defeat trolls -- including your own inner troll! I'll also share a timing attack for your brain that might just surprise you.

Let’s admit it, the tools for writing CSS aren’t very advanced. For the most part, the people who write tools don’t know about CSS and the people who know about CSS don’t write tools. Quite a conundrum! In this session, you’ll learn about good tools that can make development faster and maintenance easier. We’ll also talk a bit about where we can go from here. What tools do we need as sites are becoming more and more complex? We need to get beyond tools whose primary goal is to avoid hand-coding and realize that, as our techniques for writing CSS become more powerful, our tools can too! Session will include: * Validators * Preprocessors * Finding dead rules * Linting * CSS3 gradient tools * Performance measurement tools * Unit testing
