How to run Windows apps on Linux with Wine

With the end of support for Windows 10, Zorin OS saw over 100,000 downloads within two days. Many users are looking to run Windows applications on Linux, which can be done using Wine, a compatibility layer for running Windows applications on Linux. Wine's latest version, Wine 11, includes features such as NTSYNC support, a unified 64-bit binary, enhanced Wayland/X11 integration, improved graphics via Vulkan/D3D12, better gamepad support, and smoother performance through WoW64. To install a Windows application like Notepad++ on Linux using Wine, users need to download the installer, navigate to the Downloads directory in the terminal, and run the installer with the command PLACEHOLDER62382e95b0b64d01. If 32-bit support is missing, it can be added with the command PLACEHOLDER069a94c8ac48a981. Additionally, users can install Windows applications through Winetricks, which simplifies the process by automatically downloading and running the necessary installers. Some applications may require further configuration, particularly games, which can be adjusted using Winetricks.

How to edit text files directly from Command Prompt and PowerShell on Windows 11 — using Microsoft Edit just like Linux’s Nano

Windows 11 includes the Microsoft Edit command-line tool for editing text files directly within Command Prompt or PowerShell. The tool is under 250KB in size. To install Microsoft Edit, users can open Command Prompt as an administrator and run the command: winget install --id Microsoft.Edit. Alternatively, it can be downloaded from GitHub, but manual configuration is required. To use Microsoft Edit, users can launch it by typing PLACEHOLDERb167be8248c505bb in Command Prompt or PLACEHOLDER4905f66b5f26fc6f for administrator access. Existing text files can be edited using the command edit filename.txt, and new files can be created with the same command. Basic editing options include undo, redo, cut, copy, paste, and find and replace. Files can be saved with "Ctrl + S" and exited with "Ctrl + Q". The tool is designed for straightforward text editing without the need to switch applications.

Microsoft Adds Sudo to Windows 11 24H2 for Seamless Elevated Commands

Microsoft has introduced the sudo command in Windows 11 version 24H2, allowing users to execute commands with elevated privileges directly from a standard command prompt or PowerShell window. Users can enable this feature via Settings under System > For Developers. Sudo can run commands in three modes: “in a new window,” “with input disabled,” and “inline.” The inline mode runs the elevated command in the same console session, preserving context and variables. Microsoft has open-sourced the project on GitHub, inviting community contributions. Sudo integrates with User Account Control (UAC) for security, ensuring every elevation request is vetted. It simplifies administrative tasks for software engineers and system administrators, particularly in corporate environments where full admin access is restricted. The feature works seamlessly in Windows Terminal and supports Azure integrations. While some users have reported compatibility issues, Microsoft emphasizes that sudo is a developer tool rather than a complete replacement for Linux's sudo. Future developments may include community-driven extensions and integration with Windows Subsystem for Linux (WSL).

Docker Wine is a weird way to containerize and run Windows programs on Linux

Switching to Linux can require time to configure and may lead to challenges due to the incompatibility with Windows applications, which are often designed specifically for Windows. Docker Wine is a Docker image that provides a pre-configured Wine setup, allowing Windows applications to run in a self-contained Linux environment. This method avoids conflicts by creating a new container for each application, which disappears after use, ensuring the host system remains unaffected. Docker Wine can run both GUI applications and command-line tools, using specific commands to initiate the container and mount necessary directories. Additionally, Winetricks can be used within Docker Wine to create a persistent Wine environment for applications that require specific components. Docker Wine is particularly useful for users who need to test multiple Windows applications with conflicting dependencies without affecting their primary Linux setup.

Everyting About Postgres Security

Securing a PostgreSQL database involves following the Center for Internet Security (CIS) benchmarks, which include: 1. Installation and Patches: - Ensure PostgreSQL packages are obtained from authorized repositories, specifically the PostgreSQL Global Development Group (PGDG). - Enable systemd service files for managing PostgreSQL services. - Confirm that the data directory (PGDATA) is initialized properly. 2. Directory and File Permissions: - Set the correct file permissions mask to prevent unauthorized access. 3. Logging and Auditing: - Implement logging for monitoring and auditing purposes. 4. User Access and Authorization: - Review and configure sudo permissions to limit administrative access. 5. Connection and Login: - Avoid specifying passwords in the command line to prevent exposure in shell history or process lists. 6. PostgreSQL Settings: - Understand potential attack vectors and configure runtime parameters accordingly. 7. Replication: - Create a dedicated replication user with limited permissions. 8. Special Configuration Considerations: - Place PostgreSQL subdirectory locations outside the main data directory for enhanced security and manageability.

Updating your Linux kernel sounds scary, but here’s why it’s no different from a Windows update

Updating the Linux kernel is generally straightforward and low-risk, similar to Windows updates. Most Linux distributions, including Ubuntu, Fedora, Debian, and Linux Mint, manage kernel updates automatically through the package manager. When a new kernel is installed, the previous version remains intact, allowing users to revert to it if necessary via the GRUB boot menu. Kernel updates provide essential security patches, bug fixes, and improved hardware support. While manual installation of a kernel is possible, it is not required for most users. Tools are available for easier management of kernel versions, but the update process is designed to be user-friendly and safe.
