New Rust tool fsearch dramatically accelerates macOS file searches

·1 views

Developer Noah Dunnagan released fsearch, a high-speed file search tool for macOS, on October 8. The Rust-based application uses a memory-mapped index and a unique 64-bit character mask system to enable rapid fuzzy searches across millions of files. Instead of scanning each file individually, it employs bulk data retrieval and only updates its index when folders change. The tool's developer claims it can perform name searches across 8.3 million files in approximately 0.13 milliseconds. fsearch is open-source under the MIT license and currently requires compilation from source code.

Technical Issues Can Block AI Crawlers From Accessing Web Content

Websites that appear in Google search results may not appear in AI tools like ChatGPT due to technical barriers. Common blockers include robots.txt files that disallow AI user agents and CDN or WAF systems that challenge crawlers. Unlike Googlebot, many AI crawlers do not execute JavaScript, so they may receive empty pages from JavaScript-dependent sites. Website owners can audit these issues using tools that check robots.txt permissions and simulate crawler requests.

2017 study shows 3D-printed foil shapes can direct or block Wi-Fi signals

Researchers demonstrated in a 2017 experiment that wireless network signals extend far beyond a building's physical walls. Their study presented a method to customize indoor Wi-Fi coverage using 3D-printed plastic shapes coated in common aluminum foil. These custom reflectors, positioned around a router's antennas, could be computationally designed to strengthen or weaken signals in specific target areas. The technique showed signal strength could be adjusted by several decibels in controlled tests. This research highlights the potential to engineer a network's radio footprint as a possible security or performance measure.

Mozilla launches self-hosted Firefox Enterprise for organizational control

Mozilla launched Firefox Enterprise on October 12, 2026, combining its browser with a self-hosted management console. The product allows IT teams to centrally set browser policies, control data movement, and restrict AI tool usage without relying on cloud vendors. Initial sales are focused on France, Germany, Austria, and Switzerland. The system integrates with existing identity providers and security platforms while helping organizations meet European and international compliance standards. Mozilla has not published pricing details, offering only contact sales and demo requests instead.

Layer 2 scaling solutions tackle Ethereum's transaction speed and cost limitations

Layer 2 networks are secondary scaling solutions designed to improve blockchain performance, operating alongside primary chains like Ethereum. They process transactions off the main chain to reduce fees and confirmation times while preserving security and decentralization. These solutions are essential for Ethereum to handle higher transaction volumes, supporting decentralized applications and games. Without Layer 2 scaling, Ethereum risks becoming too slow and expensive for widespread adoption in the decentralized economy.
