Performance issues in PostgreSQL can arise as databases grow, leading to declines in query performance. To identify problematic queries, one can log long-running queries by setting the `log_min_duration_statement` parameter in the `postgresql.conf` file. The `pg_stat_statements` module can be enabled to monitor execution statistics of SQL statements, providing insights into query performance, including execution time and the number of calls. Queries with high standard deviation in execution time may indicate inconsistency, while sorting query statistics by total execution time can reveal excessive load from multiple fast queries. Real-time monitoring can be done using the `pg_stat_activity` view to check active queries and their states, and the `pg_locks` view can help identify blocked processes. The `EXPLAIN` command can analyze query execution plans, and using the `auto_explain` module can log plans for slow queries. Understanding cost parameters in query plans helps in optimizing performance, and different join methods (Nested Loop, Merge Join, Hash Join) have varying complexities and costs. To influence the planner's choice of scanning methods, configuration parameters can be adjusted, such as disabling sequential scanning. Extensions like `sr_plan`, `pg_hint_plan`, and `AQO` can further optimize query execution. Monitoring query progress can be done using dynamic views like `pg_stat_progress_*` for various commands.

Computers have a finite lifespan, and companies like Microsoft withdraw support for older devices to focus on newer models, a practice known as planned obsolescence. Microsoft is discontinuing support for the Windows 10 operating system, which means users will no longer receive security updates or technical assistance. Google has developed ChromeOS Flex, an operating system that can be installed on older Windows 10 devices, providing essential security features and updates. ChromeOS Flex offers rapid boot times and automatic updates and is compatible with a range of hardware from major manufacturers. Users must verify their device against an approved list and meet specific installation requirements, including having a 64-bit processor, at least 4 GB of RAM, and 16 GB of storage. An empty USB drive of at least 8 GB is needed to create the bootable installer for the installation process.

Microsoft's File Explorer has introduced a tab-based layout, but users still find it lacking in functionalities. The Explorer Tab Utility enhances the experience by integrating with Windows to transform new File Explorer windows into tabs. It offers hotkey commands for quick access, such as Win + E for the Home page and Ctrl + D to duplicate tabs. Users can customize hotkeys and create custom commands by specifying a name, hotkeys, scope, and action. Actions include opening File Explorer, conducting a tab search, and managing tab visibility. The utility provides a simple setup process and can be managed through a taskbar icon.

MSI has introduced PortalX, a web-based lighting platform for RGB control in PC gaming, eliminating the need for traditional software installations. PortalX serves as a centralized hub for RGB functionalities, allowing users to adjust system lighting via a webpage without downloads. It offers per-device configuration and an ‘All Sync’ toggle for cohesive aesthetics, with adjustable lighting speeds. Currently, PortalX operates exclusively within the Windows environment, which may limit compatibility for users of Linux and macOS. The platform aims to simplify RGB customization and improve integration across future product lines. PortalX is set to launch soon.

Microsoft introduced the Windows Subsystem for Linux (WSL) in the Windows 10 Anniversary Update in August 2016, initially as a tool for developers. WSL debuted as a beta version with a native-kernel translation layer, allowing Windows to run unmodified Linux ELF binaries. Its early performance was limited, leading users to prefer Linux virtual machines for full compatibility. The launch of WSL2 in May 2020 replaced the translation layer with a lightweight, real Linux kernel running in a Hyper-V utility VM, providing near-native performance and comprehensive syscall coverage. WSL2 has since seen continuous improvements, including GPU-compute and CUDA support in 2021, full GUI support for X11 and Wayland applications in 2022, and systemd support in September 2022. WSL2 approaches the performance of bare-metal Linux while integrating seamlessly with Windows, allowing users to launch a Linux shell easily. It enables developers to access the C drive and interact between Windows and Linux environments without dual-booting. WSL2 enhances productivity for data science workflows, allowing the use of tools like PyTorch with CUDA. It also offers features for non-developers, such as creating aliases for launching Windows applications and running Linux GUI applications. WSL's integration into Windows represents a significant shift, providing opportunities for users across various domains to explore Linux functionalities.
