CSS Random() Function: Say Goodbye to JavaScript for Random Animations

CSS is getting a `random()` function, a game-changer for web design! Generate random numbers directly in CSS without JavaScript for things like animation delays, randomized layouts, and random colors. The function takes min, max, and step arguments, offering various ways to share randomness – using custom properties or the `element-shared` keyword for element- or global-level sharing. The article uses examples like creating a star field, randomly placed rectangles, and photo stacks to showcase the power of `random()`, inviting developers to provide feedback to shape the feature's future.

The Colorful History of X11 Color Names: A Clash of Standards

2025-07-15

X11 color names, originating from a simple text file `rgb.txt` mapping strings to RGB values, have a long and winding history. This list, traditionally shipped with X11, became the basis for web colors when early browsers like Mosaic and Netscape adopted it. However, inconsistencies between X11 and W3C specifications, notably with "Gray," led to quirks like the lighter "Dark Gray" in CSS. Recent X11 releases now support W3C definitions, using prefixes to disambiguate conflicting names. The `rgb.txt` file also contains numerous grayscale shades and color variations, largely ignored by W3C standards. This story highlights the complexities of standardization and compatibility in technology.

Acronis True Image Causes Explorer.exe High CPU Usage

Acronis True Image Causes Explorer.exe High CPU Usage

The author discovered that after installing Acronis True Image, plugging or unplugging an external monitor would cause Explorer.exe to consume a significant amount of CPU resources, resulting in system sluggishness. Through ETW tracing and debugging, the culprit was identified as a shell extension within Acronis True Image. This extension repeatedly calls CreateToolhelp32Snapshot to retrieve a list of running processes, leading to performance issues. Acronis is aware of the problem and plans to fix it. A temporary workaround is to delete a registry key or uninstall the software.

Zero System Calls: Building a High-Performance Web Server with io_uring

2025-08-22

This article details the evolution of building high-performance web servers, from early pre-forking to select/poll, then epoll, and finally achieving zero system calls using io_uring. The author developed an experimental web server called tarweb that utilizes io_uring to asynchronously add all operations to a kernel queue, thereby avoiding the overhead of frequent system calls. Combined with kTLS and descriptorless files, further performance improvements are achieved. While challenges remain, such as memory management and io_uring's safety concerns, the project demonstrates the potential for significant performance gains in high-concurrency scenarios.

Google's Honest (and Uncommon) Take on Pixel's Water Resistance

Google's advertising materials surprisingly admit that no phone is truly waterproof or dustproof. While Pixel phones may boast an IP68 rating upon leaving the factory, this protection degrades over time due to wear, damage, or drops; liquid damage voids the warranty. This unusual transparency highlights the often-blurred line between marketing and reality in the mobile industry.

AI Revolutionizes Chip Design: Experts Weigh In

Semiconductor engineering experts discussed how AI can be applied to chip design to maximize its value and impact the design process. They envision AI shifting chip design from broadly domain-specific to a more granular approach with domains and sub-domains, catering to the unique needs of different verticals (e.g., automotive or mission-critical applications). AI tools promise to automate processes, improve debug analysis, and ultimately lead to fully autonomous workflows (Level 5), potentially reducing reliance on junior engineers. However, challenges remain in ensuring AI reliability and making its decision-making process transparent and understandable to engineers, guaranteeing design quality and efficiency.

Microsoft Curbs Vulnerability Info Access for Chinese Firms

Following July's SharePoint zero-day attacks, seemingly linked to a leak in Microsoft's early-bug-notification program (MAPP), Microsoft has reportedly stopped providing Chinese companies with proof-of-concept exploit code for upcoming vulnerabilities. MAPP typically gives vendors two weeks' advance notice before Patch Tuesday, but now access is restricted for companies in countries required to report vulnerabilities to their governments, including China. These companies will receive general written descriptions instead of PoC code. Security experts see this as a positive step to prevent future leaks.

Type-Safe PubSub and Registry for Gleam Actors

Glyn is a library providing a type-safe PubSub and registry for Gleam actors, with support for distributed clustering. Built on the Erlang syn library, it offers two complementary actor communication systems: PubSub for broadcasting events and a registry for direct command routing. Glyn seamlessly integrates with Gleam's actor model using selector composition patterns. Explicit decoders are required for type safety when sending messages between nodes in a cluster. The code examples demonstrate defining message types, creating decoders, and using PubSub and the registry for actor communication. Multi-channel actor integration is also showcased, enabling more complex communication scenarios.

The Neglected Client-Side Web: Why Nobody Cares About Slow Loading Times

2025-08-23

This article discusses the often-overlooked issue of poor client-side web experiences. While server-side problems frequently dominate discussions, the author points out the consistent neglect of slow loading times, clunky UIs, and other client-side frustrations. Using Github's recent update as an example, many users report slow performance, yet website operators prioritize server-side concerns. The author argues that websites hold significant power, leaving users with boycotts as their only recourse, which are largely ineffective. Websites often lack effective measurement of user churn, contributing to their apathy toward client-side experiences. Ultimately, the author admits to making editorial decisions that may negatively impact users but frames it as a necessary trade-off.
