Here’s how to update every app on your Windows PC with a single command

Updating Windows applications is important for accessing the latest features and protecting against vulnerabilities. Many users neglect this due to forgetfulness or the time-consuming nature of the process. The Microsoft Store and Windows Update usually provide updates for native Windows applications, but a unified method for updating all programs is lacking. Windows includes a command called winget (Windows Package Manager) that allows users to update all applications simultaneously via the command line. The command to update all apps is:


winget upgrade --all

This command updates both traditional installers and Microsoft Store apps. Users can also update individual apps by specifying the app ID, for example:


winget upgrade "Chrome"

To view all applications managed by winget, the command is:


winget list

To skip confirmation prompts during updates, users can use:


winget upgrade --all --accept-source-agreements --accept-package-agreements

For complete automation, users can create a task in Task Scheduler to run at startup with the following setup: 1. Open Task Scheduler and create a basic task named "Winget Auto Update." 2. Set the trigger to run when the computer starts. 3. Choose to start a program, entering PLACEHOLDER216a2cf34dab649d in Program/script and PLACEHOLDERbe861b18048fd836 in Add arguments. 4. Set the task to run with the highest privileges and add a 1-minute delay to ensure network connectivity. While winget does not cover every Windows application, it effectively manages most mainstream applications.

Logical replication improvements in Amazon RDS for PostgreSQL 18

PostgreSQL logical replication has operational challenges, such as the absence of generated columns in the replication stream, replication conflicts causing apply worker halts, and lingering replication slots consuming write-ahead log (WAL) files. PostgreSQL 18 introduces enhancements to address these issues, including the ability to include STORED generated columns in the replication stream with a new publication parameter, detailed conflict counters in pg_stat_subscription_stats, automatic invalidation of idle replication slots, and the ability to toggle two-phase commit settings on live subscriptions. To set up a test environment, two PostgreSQL 18 instances (one publisher and one subscriber) are required, along with an EC2 instance for executing commands. The publisher and subscriber must have specific configurations for logical replication, including enabling logical replication and setting appropriate parameters. PostgreSQL 18 allows the replication of STORED generated columns by using the publish_generated_columns parameter. The subscriber must define these columns as regular columns. The new version also enhances conflict monitoring by providing detailed counters for different types of replication conflicts. Parallel streaming is now the default behavior for subscriptions, improving efficiency. The two-phase commit feature can now be modified on existing subscriptions without needing to recreate them. PostgreSQL 18 also introduces automatic cleanup of idle replication slots, which can be configured to invalidate unused slots after a specified duration. Considerations for implementation include ensuring that the subscriber's column types match those of the publisher for generated columns, the requirement for track_commit_timestamp for certain conflict counters, and the fact that sequences are not replicated. Cleanup of replication resources is recommended after testing to prevent unnecessary costs and WAL accumulation.

Is SteamOS ready to replace Windows? I installed it so you don’t have to

The Steam Machine was announced with a starting price of 9 in the U.S. and £879 in the U.K. SteamOS is currently in beta and primarily supports the Steam Deck, Steam Machine, and Lenovo Legion Go S, with only about 19.13% of Steam users utilizing AMD GPUs compared to 72.42% using Nvidia. AMD provides broad support for Linux through open-source drivers, while Nvidia's proprietary drivers complicate SteamOS installation. Installing SteamOS requires a complete wipe of the NVMe SSD, and there is limited support documentation from Valve. Users have created guides to assist with installation, which involves adjusting BIOS settings and partitioning drives. Networking issues were encountered during installation, requiring command line updates and workarounds. SteamOS offers a console-like experience and a user-friendly interface for gaming, but it presents challenges for users who are not experienced with DIY setups.

Steam Machine review: Valve’s underwhelming living-room PC has a serious price problem

The Steam Machine is a compact gaming system measuring 16.5 × 15.5 × 15.3 cm, designed to run SteamOS and provide access to the Steam library while offering a user experience similar to consoles. It features a custom AMD CPU with six cores and twelve threads, 16 MiB of L3 cache, and a maximum clock speed of 4.86 GHz. The system includes 16 GiB of DDR5 memory and a discrete Radeon graphics unit with 8 GiB of GDDR6 video memory based on the Navi 33 architecture, operating with 28 compute units and a power budget of 110 watts. Storage consists of an NVMe drive with approximately 1.9 TB of space and a zram swap of around 7.6 GiB. The Steam Machine runs SteamOS 3.8.9 in its x86-64 version, allowing it to function as either a Linux PC or a gaming interface. Connectivity options include one HDMI 2.0 port, one DisplayPort 1.4 port, four USB-A ports, a USB-C port, Gigabit Ethernet, Wi-Fi 6E, and Bluetooth 5.3.

Implementing real-time change data capture with Debezium for Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL

Amazon Aurora PostgreSQL-Compatible Edition and Amazon RDS for PostgreSQL now support native streaming replication, allowing data changes to flow from source databases. Organizations often struggle to capture and propagate these changes in real time without affecting database performance. Traditional ETL pipelines can introduce significant delays, leading to outdated data and missed opportunities. Debezium is an open-source platform for change data capture (CDC) that monitors databases and streams changes to applications or data pipelines, enabling real-time data synchronization. The CDC solution combines PostgreSQL's logical replication with Debezium's change capture framework, focusing on Amazon Aurora for PostgreSQL. To implement this solution, logical replication must be enabled on Amazon Aurora through DB cluster parameter groups. Debezium connectors monitor the database's Write-Ahead Logging (WAL) via logical replication slots, converting transaction logs into structured event streams. Key components of the solution include: - Amazon Aurora for PostgreSQL as the source database with logical replication enabled. - A Debezium PostgreSQL connector running on MSK Connect for change capture. - Amazon MSK for message streaming. - An Amazon EC2 instance for testing and consuming change events. Steps to implement the solution include: 1. Creating an Amazon Aurora for PostgreSQL DB cluster and enabling logical replication. 2. Creating an Amazon MSK serverless cluster. 3. Setting up an Amazon EC2 instance to install Kafka and connect to the database. 4. Creating a custom plugin for Amazon MSK to replicate changes from RDS for PostgreSQL. 5. Uploading the custom plugin to an Amazon S3 bucket. 6. Storing credentials in AWS Secrets Manager and creating an IAM role for MSK Connect. 7. Testing the solution by verifying data replication and monitoring real-time changes. Monitoring can be done through CloudWatch Logs and the MSK Connect console, addressing common issues like replication slot lag and connector failures. To avoid charges, resources created during the implementation should be deleted in the correct order.

Windows zero-days expose gaps in built-in security protections

Two Windows zero-day vulnerabilities, YellowKey and GreenPlasma, have been identified. YellowKey targets the Windows Recovery Environment (WinRE) on Windows 11 and Windows Server 2025, allowing attackers with physical access to bypass BitLocker protections using a USB device. GreenPlasma affects Windows 10, Windows 11, and Windows Server environments with active Collaborative Translation Framework Monitor (CTFMON) sessions, enabling local privilege escalation from a standard user account to SYSTEM-level privileges. Both vulnerabilities require either physical or local access to exploit. Microsoft has not yet released patches for these vulnerabilities, prompting organizations to enhance their security measures and operational resilience. Recommendations include reassessing physical security, limiting local administrative access, and implementing multifactor authentication and robust credential management practices.
