Connecting .NET Lambda to Amazon Aurora PostgreSQL via RDS Proxy

Many organizations are modernizing legacy .NET applications while reducing database costs and enhancing scalability, particularly during migrations to AWS Lambda and transitions from SQL Server to Amazon Aurora PostgreSQL-Compatible Edition. The process involves connecting Lambda functions to Aurora PostgreSQL using Amazon RDS Proxy, with AWS Secrets Manager managing secure credential storage. The architecture includes a .NET Lambda function interfacing with Aurora PostgreSQL via RDS Proxy, which provides connection pooling to minimize database connection overhead. The solution requires a CloudFormation template to provision resources such as a VPC with private subnets, an Aurora PostgreSQL cluster, RDS Proxy, and Secrets Manager. The RDS Proxy is configured with parameters including PostgreSQL engine family, idle client connection timeout, and Secrets Manager secret. A Windows EC2 instance is provisioned, and access is facilitated through AWS Systems Manager Fleet Manager. The solution includes creating a sample table named "employee" in the database and a new .NET Lambda project that utilizes Npgsql for database connections. The Lambda function is deployed using the AWS CLI, and testing involves invoking the function and retrieving logs from Amazon CloudWatch. Finally, resources created during the process should be deleted to prevent ongoing charges.

League of Legends lead Phroxzon says “frustrating” counters like Mel are part of the MOBA’s “secret sauce”

Matt 'Phroxzon' Leung-Harrison, lead gameplay designer for League of Legends, engaged with a group of 20 players to discuss champion balance, focusing on Mel, whose abilities can disrupt opponents. He described Mel as "a balanced champion," though players expressed frustration over her matchups. Phroxzon acknowledged that there are moments where Mel can feel overwhelmingly powerful and emphasized the importance of diverse gameplay experiences. He noted that navigating difficult matchups is integral to the game and encouraged players to develop strategies against challenging champions. He also discussed the concept of 'loser's queue' and the psychological aspects of player perceptions in competitive environments. Additionally, he addressed the balance between introducing changes through patches and maintaining game stability, suggesting that new champion releases contribute to player growth and understanding. Riot Games is committed to evaluating champion dynamics and player experiences in the evolving landscape of League of Legends.

Antivirus protection built into Windows

Windows 11 includes Microsoft Defender Antivirus, which is active from the moment the device is powered on and integrated into the operating system. It continuously updates to protect against various threats, including malicious files and unsafe links. Microsoft Defender SmartScreen evaluates the safety of websites and downloads, providing warnings for dubious content. Smart App Control prevents untrusted applications from executing, while Controlled folder access protects personal files from unauthorized modifications. Users can verify the operational status of Microsoft Defender Antivirus through Windows Security settings. Best practices for maintaining security include keeping the antivirus updated, using a single real-time antivirus engine, and enhancing security habits. Microsoft Defender Antivirus is generally sufficient for everyday risks, but additional third-party antivirus solutions may be considered based on individual needs.

Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.

This new app may free Galaxy Watch owners from Samsung’s phone-locked features

A new application called the GeminiMan Wellness Companion has been developed for Galaxy Watch users by Dante63, who previously created a patched version of the Samsung Health Monitor. The app allows users to record electrocardiogram (ECG) data from the Galaxy Watch, providing detailed reports and AI-driven analysis through a mobile app. It can track heart rhythm and rate, flagging abnormal rhythms, which the Samsung Health Monitor does not. Users can personalize their measurements with notes and create multiple profiles for different users. The app ensures data security through encryption and offers export options for ECG reports in CSV or PDF formats. Future updates will include blood pressure recording and additional health metrics like blood oxygen levels and sleep patterns. The development roadmap is available on the GeminiMan Wellness Companion GitHub page.

Windows is sabotaging your expensive hardware, and these are the biggest ways how

Modern PCs, even with mid-range hardware, can experience performance issues not solely due to hardware limitations but because of how Windows operates. The operating system runs numerous background services that consume resources, including Connected User Experiences and Telemetry, Diagnostic Policy Service, and Windows Error Reporting. These services log activity and send data to Microsoft, leading to unexpected CPU spikes and disk usage. Startup applications, such as Microsoft Teams and OneDrive, also contribute to longer boot times and increased resource usage. Users should monitor and limit these applications to improve startup performance. Legacy features like SysMain, Windows Search indexing, and automatic folder type discovery can hinder performance on modern systems, as they were designed for older hardware and can cause unnecessary disk activity. Microsoft services like Copilot and OneDrive continuously run in the background, consuming memory and CPU resources, which affects overall system performance. Windows' power management settings prioritize energy efficiency over performance, leading to inconsistent responsiveness and delays during tasks. This conservative approach impacts various components, making the system feel sluggish.

Bitchat Review: How Jack Dorsey’s Private Offline Messenger Works

Bitchat employs the Noise Protocol Framework, specifically the XX pattern, for encrypted and authenticated communication. The Android version uses X25519 for key exchange and AES-256-GCM for message encryption. Bitchat operates without a central infrastructure, phone numbers, or traditional accounts, which reduces data collection and risks of censorship and surveillance. The app relies on Bluetooth connectivity, requiring physical proximity between users, which can enhance security but may lead to device identification. Metadata about nearby devices and connection instances may still be retained. Bitchat has not yet undergone a comprehensive external security audit, raising concerns despite its focus on privacy and encryption.
