Running A Game On A PC With No System RAM

The video by PortalRunner explores alternatives for running modern software in environments with limited RAM, particularly in the context of the challenges posed by the absence of DDR5 memory. It discusses various strategies, including: - Testing Linux with specific boot arguments, which can lead to system failures if insufficient RAM is allocated. - Maximizing swap usage on SSDs, which, despite being faster than HDDs, results in sluggish performance due to overhead. - Utilizing video RAM from GPUs as a substitute for system RAM, which also suffers from significant overhead. - Modifying a CoreBoot BIOS image to use CPU cache memory, allowing lightweight software to run without system RAM, although this method raises scalability and practicality concerns. The exploration highlights creative responses to RAM shortages in computing.

Fake Huorong Site Delivers ValleyRAT Backdoor in Targeted Malware Campaign

A cyber operation is targeting users of Huorong Security antivirus software through a typosquatted domain, huoronga[.]com, which mimics the legitimate site huorong.cn. Users who mistakenly visit the counterfeit site may download a file named BR火绒445[.]zip, which contains a trojanized installer that leads to the installation of ValleyRAT, a remote access trojan. The malware employs various techniques to evade detection, including using an intermediary domain for downloads, creating Windows Defender exclusions, and establishing a scheduled task for persistence. The backdoor facilitates activities such as keylogging and credential access while disguising its operations within legitimate processes like rundll32.exe. Attribution points to the Silver Fox APT group, and there has been a significant increase in ValleyRAT samples documented in recent months. Security measures include ensuring software downloads are from the official site and monitoring for specific malicious activities.

Why Windows 11 feels slower than Windows 10—and why it’s not just in your head

Windows 11 features a modern architecture with advanced schedulers and SSD support, but many users experience sluggishness, with delays in menus and dialog boxes. This perception of reduced responsiveness compared to Windows 10 has been linked to the use of XAML, which modernizes traditional desktop components but introduces performance issues due to added abstraction layers. Disabling animations does not resolve the delays, which are attributed to XAML's reliance on GPU acceleration for simple tasks, leading to inefficiencies. The cumulative effect of these micro-delays, measured in milliseconds, contributes to an overall feeling of sluggishness, regardless of high-end hardware. Microsoft's design choices prioritize visual consistency and modern UI technology, resulting in trade-offs in everyday responsiveness. The slower perception of Windows 11 compared to Windows 10 is rooted in these deliberate technical decisions.

AlloyDB managed connection pooling

AlloyDB for PostgreSQL is a fully managed database service designed for enterprise workloads, combining PostgreSQL's strengths with Google Cloud technology for enhanced performance, scalability, and availability. A new feature, managed connection pooling, addresses the challenges of inefficient database connection management, which can lead to performance degradation, resource exhaustion, and reliability issues. Managed connection pooling maintains a cache of active database connections, allowing applications to reuse connections instead of creating new ones for each request, thus reducing latency and resource consumption. This feature is tightly integrated into AlloyDB, simplifying operations and optimizing performance and security. It offers two configurable pooling modes: transaction mode, which maximizes reuse for short transactions, and session mode, which maintains a connection for the entire session. Enabling managed connection pooling can increase transactions per minute by up to five times, support over three times more concurrent connections, decrease connection latency, and improve reliability during traffic spikes. UKG, a provider of HR solutions, has adopted this feature to enhance the performance and scalability of their applications. To enable managed connection pooling, users can activate it in the Google Cloud console and connect applications using standard PostgreSQL drivers to the designated port.

Malicious Rust Crate Delivers OS-Specific Malware to Web3 Developer Systems

A malicious Rust package named "evm-units," uploaded by a user called "ablerust" to crates.io in mid-April 2025, poses a significant threat to developers on Windows, macOS, and Linux. It has over 7,000 downloads and is designed to execute its payload stealthily, depending on the victim's operating system and the presence of Qihoo 360 antivirus. The package disguises itself as a function that returns the Ethereum version number and can detect Qihoo 360 antivirus software. It downloads and executes different payloads based on the operating system: a script for Linux, a file for macOS, and a PowerShell script for Windows. If the antivirus is not detected, it creates a Visual Basic Script wrapper to run a hidden PowerShell script. The package targets the Web3 community, particularly developers, and is linked to the widely used "uniswap-utils" package. Both "evm-units" and "uniswap-utils" have been removed from the repository.

Microsoft raises the security standard for next major Windows Server release – Microsoft Windows Server Blog

Microsoft plans to elevate the security standards for Windows Server hardware certification in its next major release, mandating that TPM 2.0 is installed and enabled by default and that Secure Boot is activated by default on systems pre-installed with the upcoming Windows Server. These requirements will apply to all servers running Windows Server, including bare metal setups, virtual machines on Hyper-V, and third-party hypervisors approved through the Server Virtualization Validation Program (SVVP). Secure Boot ensures that only trusted operating systems are loaded during the boot process, mitigating risks from malware. TPM 2.0 provides hardware support for secure measurements and key storage, enhancing security further by allowing secure capture and storage of the boot sequence. BitLocker leverages TPM 2.0 to ensure volumes are decrypted only if the system booted correctly. The enforcement of these requirements will apply to new server platforms introduced after January 1, 2021, while existing platforms will receive Additional Qualification certification to help customers identify compliant systems.

OAuth 2.0 authorization in PostgreSQL using Keycloak as an example

The Tantor Postgres 17.5.0 DBMS introduces OAuth 2.0 Device Authorization Flow for secure access to PostgreSQL via external identification providers like Keycloak. This feature will also be available in PostgreSQL 18. The setup involves configuring Keycloak, preparing PostgreSQL, writing an OAuth token validator, and verifying authorization through psql. Keycloak is an open-source access control system that simplifies user management and provides a single sign-on experience. To launch Keycloak, a Docker image is used, and an admin user is created with the username and password set to "admin." The process includes creating a realm named "postgres-realm," adding users (e.g., a user named "alice"), establishing client scopes, and creating a client named "postgres-client" with OAuth 2.0 Device Authorization Grant enabled. PostgreSQL requires specific configurations for OAuth operations, including creating a user, adjusting parameters in the postgresql.conf file, and setting up user mapping in pg_ident.conf and pg_hba.conf files. A role named "alice" is created with login rights. The postgresql.conf file specifies the OAuth validator library, and user mapping can be done via pg_ident.conf or a custom validator. The pg_hba.conf file is configured to allow client login to the database using OAuth, specifying the issuer parameter pointing to the Keycloak discovery service URL. A custom validator is implemented to handle token validation, ensuring that the required scopes are present in the received token. The validator includes functions for startup, shutdown, and token validation, which processes the token content and checks permissions against the HBA configuration.
