Fastfetch 2.61 System Information Tool Drops Windows 7 and 8 Support

Fastfetch version 2.61 has been released, discontinuing support for Windows 7 and 8, with Windows 8.1 as the oldest supported version. The GPU module on Windows now uses DXCore for improved detection accuracy, available only on Windows 10 and later. In the Windows Subsystem for Linux (WSL), the GPU module has been optimized for speed but may have reduced accuracy due to the removal of directx-headers. On Linux, Fastfetch has transitioned to a pure C implementation, enhancing performance and simplifying the build process. New features include a brightness option for color display, detection of Bluetooth keyboards on Linux, display of empty memory slots, support for GlazeWM detection, identification of marketing product names on Asahi Linux, and recognition of M5-based Mac models on macOS. Improvements in hardware detection and system reporting have been made across all platforms, with enhanced SMBIOS data handling and reliability for Intel-based Macs. Stability improvements for terminating child processes on Windows have also been implemented. Critical fixes address missing memory device reporting, CPU cache deduplication issues, accurate window manager version reporting for niri, SSID decoding problems, and a Windows-specific issue affecting the command prompt code page.

How Advanced Browsing Protection Works in Messenger

Advanced Browsing Protection (ABP) in Messenger enhances user privacy by warning users about potentially harmful links shared in end-to-end encrypted communications. It analyzes links using on-device models and a dynamic watchlist of millions of potentially malicious sites, utilizing cryptographic techniques to maintain user privacy. ABP is based on a cryptographic primitive called private information retrieval (PIR), which minimizes the information a server learns from client queries. The system also employs oblivious pseudorandom functions (OPRFs) and manages URL queries through a privacy-preserving URL-matching scheme. The server groups links by domain, allowing clients to request a single bucket for domain-specific path components, and generates a ruleset to balance bucket sizes. To safeguard client queries, AMD's SEV-SNP technology creates a confidential virtual machine (CVM) that processes hash prefixes securely, generating attestation reports for integrity verification. The use of Oblivious RAM and Oblivious HTTP (OHTTP) enhances privacy by preventing exposure of memory access patterns and stripping identifying information from client requests. The lifecycle of an ABP request includes pre-processing phases where the server updates the URL database and computes rulesets, followed by client requests that involve calculating bucket identifiers, sending encrypted requests through a proxy, and checking for unsafe URLs based on server responses.

Messenger can warn you about sketchy links without knowing what you clicked

Meta has introduced Advanced Browsing Protection (ABP) in its Messenger application to enhance user safety by identifying harmful websites during chats. ABP utilizes a constantly updated watchlist of potentially harmful websites, improving upon the existing Safe Browsing feature. Due to end-to-end encryption, Messenger cannot access message content or links, so ABP uses cryptography and secure computing techniques for link verification without exposing them. When a user clicks a link, Messenger checks it against a blocklist using a privacy-preserving query system. Users can enable or disable ABP in the Messenger app under Settings, Privacy & safety, and Safe browsing. If the option is not visible, users may need to update the app.

Chrome will borrow Gemini’s cross-app powers in upcoming agentic upgrade

Google Chrome is set to introduce a significant upgrade with a feature called Gemini, which will enhance user experience through "Personal Intelligence." This feature will allow users to access information from various Google apps directly within the browser and perform tasks autonomously, such as clicking links and typing. Personal Intelligence has already been rolled out in mobile applications and will be integrated into Chrome to provide tailored responses by synthesizing context from multiple Google apps. Users will be able to draft emails in Gmail using information from web pages without switching windows. Personal Intelligence will be an opt-in feature, allowing users to control their data connections. The enhancements will initially be available on desktop versions of Chrome, with previews for Google AI Pro and Ultra users in the U.S. expected in the coming months.

Создана торрент-сеть, которую невозможно взломать или заблокировать

In the Netherlands, Tribler is a fully decentralized torrent client developed by Professor Johan Pouwelse from Delft University of Technology, designed to operate without central servers and resist state-imposed sanctions. Users can search for files directly within the application, which organizes content into channels, including the popular RuTracker unofficial channel, associated with the Russian tracker RuTracker, which has been blocked in Russia since November 2015. Tribler is available on multiple platforms and is open-source, with version 7.5.1 released on June 25, 2020. The absence of central servers allows for uninterrupted access as long as at least one user is connected, and the system operates without moderators, although user ratings can filter out harmful content. An integrated anonymizing network was introduced in September 2014 to enhance user privacy. As of June 2020, RuTracker unofficial had over 2 million torrents, and other channels like YIFY, MVGroup, EZTV, and NYAA also attract users. Despite RuTracker's ban, it remains accessible through Tribler, and the site continues to operate by allowing users to create personal copies to circumvent blocks.
