Dragon Age setting creator says AI push is a delusion of the executive class that’s a ‘virulent plague’ on games

David Gaider, a veteran of BioWare and creator of the Dragon Age universe, expressed concerns about generative AI in gaming, calling it a "virulent plague" that negatively impacts creativity and job opportunities. He criticized the current use of AI for producing subpar results and diminishing entry-level opportunities for writers. Gaider suggested that AI should be used as a supportive tool for mundane tasks, allowing human writers to focus on creative work, but noted that AI is currently taking on critical roles instead. He emphasized the importance of nurturing new talent and cautioned against eliminating tasks essential for training junior developers. Gaider also raised ethical concerns about AI's reliance on datasets that may lack consent from original creators, warning of potential legal issues. He expressed skepticism about AI's readiness for widespread application in the industry, advocating for caution until proper regulation and ethical data training are established.

Meta pauses controversial employee-tracking program after security review

Meta has suspended its employee-tracking program after an internal security review revealed excessive accessibility to sensitive data collected from staff laptops. The program, part of the Model Capability Initiative (MCI), aimed to gather detailed information on employee interactions with work devices, including mouse movements, click locations, keystrokes, and screen content. Concerns arose regarding the privacy and security of the collected data, which included AI prompts, transcriptions, private conversations, and performance-related information. The initiative faced backlash, particularly after an engineer criticized "laptop surveillance," leading to a petition for its termination. The monitoring software was deployed on US workers’ laptops without an opt-out option, capturing comprehensive behavioral datasets. The situation highlighted significant legal and regulatory challenges, as well as the risks associated with managing sensitive data. Access controls, data minimization, and retention policies are critical to mitigate potential breaches.

PostgreSQL 18 on Amazon Aurora and Amazon RDS: Security, monitoring, and developer enhancements

PostgreSQL version 18 has deprecated MD5 password authentication in favor of SCRAM-SHA-256, with a new parameter, md5_password_warnings, enabled by default to log deprecation warnings. It has enhanced monitoring capabilities by adding columns to pg_stat_database and pg_stat_statements to track parallel worker activity, with the default max_parallel_workers_per_gather set to 0 in Aurora PostgreSQL. The pg_stat_subscription_stats view now includes new columns for tracking conflict types in logical replication. Optimizer statistics are automatically transferred during upgrades, while uuidv7() generates timestamp-ordered UUIDs. The default streaming option for CREATE SUBSCRIPTION has changed to parallel, and the idle_replication_slot_timeout parameter automatically invalidates inactive replication slots. Enhancements to the COPY command include REJECT_LIMIT for error tolerance and a silent LOG_VERBOSITY level. OLD and NEW aliases have been introduced in RETURNING clauses for various DML commands.

PostgreSQL 18 on Amazon Aurora and Amazon RDS: Performance enhancements

PostgreSQL 18 addresses common performance challenges for users, including managing query performance across composite indexes, diagnosing memory spills in materialized Common Table Expressions (CTEs), and upgrading major versions without plan regressions. Key enhancements include skip scan optimization for multicolumn indexes, improved EXPLAIN functionality, and optimizer statistics that persist through major version upgrades. Skip scan optimization allows PostgreSQL to efficiently utilize multicolumn B-tree indexes even when leading columns are not specified in the WHERE clause, significantly improving query performance. The EXPLAIN command has been enhanced to include buffer statistics by default, providing deeper insights into query execution and resource usage. PostgreSQL 18 also introduces visibility into the storage of materialized nodes in query plans, indicating whether intermediate results were stored in memory or spilled to disk. A new metric, Index Searches, has been added to EXPLAIN ANALYZE output, indicating how many times the database traversed the index tree during query execution. Additionally, Self-Join Elimination (SJE) automatically detects and removes unnecessary inner joins of a table to itself, optimizing query performance. The autovacuum mechanism has been improved with the introduction of autovacuum_vacuum_max_threshold, which caps the number of dead tuples that can accumulate before autovacuum triggers a VACUUM, addressing issues with large tables. The vacuum_truncate parameter provides a server-wide control point to disable VACUUM’s file truncation behavior, reducing locking issues on busy systems. PostgreSQL 18 also separates the allocation of autovacuum worker slots from their usage, allowing for dynamic adjustments to autovacuum_max_workers without requiring a server restart. Finally, new columns in pg_stat_all_tables track cumulative time spent on maintenance operations, providing better insights into maintenance overhead for each table.

Microsoft Teams will auto-detect when you’re at the office via Wi-Fi, roll out confirmed, but you can opt-out

Microsoft is rolling out a feature called "Workplace check-in" that allows organizations to track employee presence in the office through Wi-Fi connectivity, integrated with Microsoft Teams and configured via Microsoft Places. This feature, first noted in September 2025, will not be enabled by default. It logs an employee's location when they connect to the company’s Wi-Fi, such as when they arrive at the office. The rollout was delayed due to privacy concerns, but Microsoft is moving forward, ensuring users can control their participation. The feature does not provide real-time tracking like mapping services but indicates presence based on Wi-Fi connection. Users must grant location access through their operating system, and if they decline, IT policies cannot override this choice. Teams’ Workplace check-in is disabled by default and can be activated by IT administrators with two options: Inform mode, which notifies users of the feature and allows opting out, and Ask mode, which requests permission to share location data. Microsoft clarifies that the feature is not intended for surveillance and does not track movements over time. Employees can choose whether their presence is visible to others while on-site. The initial rollout is tied to organizations using the Microsoft Places directory, and as organizations set up the feature, more users will likely be affected. Additionally, Microsoft is enhancing Teams with improvements for speed and a new user interface for meetings.

Microsoft Open-Sources PostgreSQL Extension for In-Database Durable Execution

Microsoft has introduced pg_durable, a PostgreSQL extension that enables developers to execute durable workflows within the database, reducing the need for external orchestration systems. It simplifies workflow management by allowing developers to express long-running, fault-tolerant SQL functions directly in SQL, managing execution concerns like retries and recovery. Workflows are defined in SQL, with the extension handling retry states, progress tracking, and checkpointing. A pg_durable function operates as a graph of SQL steps that can resume from the last durable checkpoint after a failure. The extension preserves execution states within PostgreSQL tables, ensuring workflows can withstand crashes and restarts. It includes a domain-specific language (DSL) for scheduling and parallel execution. An example of a durable function is provided, demonstrating sequential and parallel execution using specific operators. pg_durable is particularly useful for vector embedding pipelines and scheduled maintenance tasks. Architecturally, it consists of a PostgreSQL extension and a background worker built on Rust libraries, without any external control plane. Durable execution allows long-running workflows to automatically resume from failure points, simplifying distributed system architecture.

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.

PostgreSQL Dump and Restore: The Complete pg_dump Guide

pg_dump is a utility for exporting a PostgreSQL database into a file, which can be restored on the same or different servers. It exports a single database's tables, views, sequences, functions, indexes, triggers, and in-database grants but does not include roles, tablespaces, or server-level configurations. To capture global objects, pg_dumpall --globals-only should be executed prior to the per-database dump. pg_dump requires CONNECT and SELECT privileges on all tables and sequences within the target database, and a dedicated backup role is sufficient for single-database dumps, while superuser access is needed for global objects. pg_dump supports various output formats: plain SQL (.sql), custom binary (.dump), directory of files, and tar archive (.tar), each with different capabilities for restoration and compression. The custom format allows for selective and parallel restoration. For non-interactive use, credentials can be stored in a .pgpass file or passed via the PGPASSWORD environment variable. Restoration methods depend on the dump format: psql is used for plain SQL files, while pg_restore is used for custom and directory formats. The restoration process requires the target database to be created beforehand. Version mismatches between pg_dump and pg_restore can lead to failures, so it's essential to ensure that the binaries are version-matched. In Docker, pg_dump and pg_restore can be executed within containers, but care must be taken to manage credentials and ensure version compatibility. Exit codes from pg_dump should be checked to confirm successful operations.
