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.

Microsoft Copilot Vulnerability: Audit Logs are Broken

A security researcher discovered a critical vulnerability in Microsoft Copilot: it sometimes accesses files and returns information without logging the action in audit logs. Worse, users can instruct Copilot to access files without leaving a trace. While Microsoft has fixed the vulnerability, their decision not to notify customers raises serious concerns about transparency and customer responsibility. This flaw poses a significant threat to organizations relying on audit logs for security and compliance, particularly in highly regulated industries like healthcare and finance.

The Curious Case of Emoji Length in JavaScript: UTF-8, UTF-16, UTF-32, and Grapheme Clusters

2025-08-22

This article delves into the discrepancies in emoji string length across different programming languages. For example, in JavaScript "🤦🏼‍♂️".length is 7, while in Python it's 5 and in Rust, 17. This stems from variations in how languages handle string encoding (UTF-16, UTF-8, etc.) and character units (Unicode scalar values, extended grapheme clusters, etc.). The author argues that remembering the length in the native encoding is reasonable, but other lengths (like extended grapheme clusters) should be computed on demand to avoid unnecessary storage overhead and synchronization issues. The article further analyzes the pros and cons of different encoding schemes, highlighting UTF-8's advantages in storage and interchange. Finally, it tackles the issue of fair length quotas, demonstrating that there's no simple way to fairly measure information density across languages, illustrating this with translations of the Universal Declaration of Human Rights.

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.

Making a JavaScript-Optional Online Board Game: A Case Study in Progressive Enhancement

2025-08-23

This article details how an online board game website achieved fully optional JavaScript functionality using server-side rendering, standard HTML elements, and URL parameters. The author replaced real-time updates with page auto-refresh, and used native HTML elements for dropdown menus and modals. While increasing server load and code complexity, this approach improved initial page load speed and site robustness, yielding unexpected benefits like more semantically correct HTML. However, the author concludes the extra effort isn't worthwhile unless targeting a very JavaScript-averse audience, and plans to eventually remove the extra code.
