In Windows 11, certain names such as CON, PRN, AUX, and NUL are reserved as they correspond to specific devices, preventing users from naming folders with these terms. These reserved names date back to DOS 1.0, where folders did not exist. The names have specific functions: CON refers to the console, PRN to the printer, AUX to an auxiliary device, and NUL to a null device that discards output. Attempts to rename a folder to any of these names result in an error message indicating the device name is invalid. Adding extensions to these names does not bypass the restriction, as names like NUL.txt are still treated as equivalent to NUL. Despite some changes in Windows 11, the prohibition against using these reserved names for files or folders remains in place due to legacy compatibility concerns.

The Federal Trade Commission (FTC) has raised concerns about Avast's data collection practices through its antivirus software and browser extensions since at least 2014, alleging that it collected sensitive user information. The FTC's settlement order restricts Avast from misrepresenting its data usage and requires the company to pay a total of .5 million to affected users. Claims related to the settlement must be submitted by 2025, with initial payments starting in December 2025. A second round of payments will distribute over .5 million to 91,093 individuals who accepted their initial compensation, with instructions for cashing checks and receiving payments via PayPal and Zelle.

Devart has released dbForge 2026.2, a unified database management ecosystem for PostgreSQL developers, featuring an embedded PostgreSQL Debugger that allows for efficient error tracking in server-side code. The Debugger enables breakpoints, step-through code execution, and real-time monitoring of variables and query results. Visual editors for PostgreSQL event triggers, functions, and procedures have been introduced, allowing for easier management without manual SQL writing. The dbForge AI Assistant now offers expanded context awareness, enabling users to attach various documents and select from multiple AI models for generating relevant SQL code. A free Express edition of the AI Assistant is available, with limited features compared to paid plans. Additionally, new SQL refactoring commands and schema comparison improvements have been implemented, along with updates for compatibility with MySQL 26.7 and MariaDB 13.x.

The Nebius Managed PostgreSQL team developed a solution for AI workloads using CloudNativePG and Kubernetes, resulting in improved backup and restore times by transitioning from Barman to WAL-G, reducing a 1.5 TB backup duration from over a day to two hours. Since its launch in 2025, the service supports hundreds of production clusters and manages tens of tebibytes of data. Key features include high availability, point-in-time recovery, automated failover, compressed and encrypted backups, rapid restoration, connection pooling, and strict synchronous replication for zero data loss. Kubernetes and CloudNativePG were chosen for their advantages, including out-of-the-box features and open-source distribution. Each cloud project has a separate MK8s cluster for customer isolation and security. Persistent data is stored on fault-tolerant SSD drives, enabling swift instance migration during failures. Regular physical backups are archived, allowing restoration within a seven-day window with a single click. The transition from Barman to WAL-G addressed slow backup and restoration times and resource control limitations. With WAL-G, backups and restorations for a 1.5 TB cluster improved to two hours and one hour, respectively. PgBouncer was implemented to manage database connections effectively, reducing connection storms during peak AI workload traffic. Two vector search extensions, pgvector and pgvectorscale, are available to cater to different memory and dataset needs. Benchmarking showed that Nebius performs competitively with AWS at a lower cost. The infrastructure integrates cloud engineering principles with specialized expertise to meet AI workload demands.

In the early days of computing, specifically with MS-DOS and early Windows, file names were limited to eight characters and a three-character extension, leading to cryptic naming conventions. With the introduction of Windows 95, this limitation was lifted, allowing file names up to 255 characters and longer extensions, significantly improving organization and usability of various file formats like JPEG and HTML.
