Microsoft is updating Windows Production CA, IT admins and devs should take action ASAP

Microsoft is updating its Windows certificate framework, focusing on Secure Boot certificates and the expiration of certain Windows 11 Insider certificates. A new certificate update is crucial to prevent disruptions in applications and IT processes. Microsoft is phasing out outdated certificates and modernizing signing algorithms, with the Windows Production Public Certificate Authority (PCA) 2011 set to expire on October 19, 2026. It will be replaced by a new PCA, and stronger signing algorithms like RSA-3072 and SHA-384 will be adopted later this year. Applications relying on outdated technologies may fail due to these updates. IT administrators and application developers are advised to review software, adopt algorithm-agnostic approaches, test certificate changes, and check private trust stores for issues. The timeline includes the PCA expiration in 2026, a transition to stronger configurations later that year, and a default to post-quantum cryptography (PQC) in 2027, with ongoing updates as security needs evolve.

Are your PC games crashing after the latest Windows 11 update? Microsoft is investigating whether a nasty new bug is the cause

Windows 11's latest update has caused significant issues for various PC games, with Microsoft acknowledging that some games have become unresponsive following the August patch. Affected titles include Arc Raiders, Marvel Tokon: Fighting Souls, and The Finals. Microsoft is investigating potential links to peripherals or internal components with RGB lighting, which may have problematic drivers like inpoutx64. Discussions suggest that tightened kernel handle validation in the update has exposed driver glitches, leading to game crashes. Players who have not installed the August update may remain unaffected. Suggested workarounds include removing the inpoutx64 driver file by using Command Prompt commands to stop and delete the driver, followed by deleting any instances of the file in the system directory. Many gamers are expressing frustration on social media, with some suggesting alternatives like Linux for a more stable gaming experience. Microsoft is currently investigating the situation.

Migrate Amazon Aurora PostgreSQL across major versions with active Debezium CDC connectors using native logical replication

Organizations using Debezium Change Data Capture (CDC) connectors on Amazon Aurora PostgreSQL-Compatible Edition face challenges during major database version upgrades. In-place upgrades require downtime, while blue/green deployments disrupt CDC event pipelines. A method using PostgreSQL's native logical replication allows migration between a source cluster (current version) and a target cluster (new major version) without a full connector re-snapshot. This approach minimizes risks of data loss and allows existing Debezium connectors to operate on the source during synchronization. The cutover process involves disabling the replication subscription, synchronizing sequences, creating a new Debezium replication slot on the target, and redirecting the connector, resulting in a brief pause for Kafka consumers. Prerequisites for this method include enabling logical replication on the source cluster, ensuring the target cluster is provisioned in the same VPC, and confirming that tables participating in CDC have primary keys. The process involves configuring parameter groups, creating publications, and establishing subscriptions for logical replication. During cutover, application writes are halted, and replication lag must be monitored to ensure it reaches zero before proceeding. After the cutover, ongoing monitoring of replication health and Kafka consumer offsets is necessary. Common failure scenarios include Aurora writer failover, Debezium connector stalls, large messages exceeding Kafka limits, DDL changes during synchronization, and long-running transactions blocking lag drain. Each scenario has specific symptoms, detection methods, and resolutions. Post-migration, organizations should establish monitoring for replication lag growth and Kafka consumer offset divergence. Automation can streamline the migration process for organizations managing multiple clusters, utilizing AWS Cloud Development Kit (CDK) constructs for cluster provisioning, schema replication, and cutover orchestration. After verifying stable operation on the target cluster, the old Debezium connector and source cluster can be decommissioned. Limitations include the absence of failover slots on Aurora PostgreSQL 17 and the need to handle TOAST columns appropriately.

Enforcing TLS and managing certificate rotation for RDS and Amazon Aurora PostgreSQL

When an Amazon RDS certificate expires and the application’s trust store is outdated, it can cause connection failures. AWS announces Certificate Authorities (CA) rotation events in advance and provides management tools, but a lack of proactive certificate lifecycle management can lead to unplanned downtime. Default configurations for RDS and Amazon Aurora allow both encrypted and unencrypted PostgreSQL connections, which can expose sensitive data if not properly configured. AWS manages the Certificate Authority infrastructure and provisions server certificates, while users are responsible for enforcing TLS usage and managing the rotation lifecycle. Amazon RDS employs a managed Certificate Authority hierarchy that issues server certificates for each database instance, supporting TLS 1.2 and TLS 1.3. The solution to enforce TLS includes server-side enforcement with the rds.force_ssl parameter, client-side verification with the sslmode=verify-full parameter, and automated lifecycle monitoring using Amazon EventBridge, AWS Lambda, and Amazon CloudWatch. Prerequisites for implementing this solution include an AWS account with an Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL instance, IAM permissions for relevant services, a compatible PostgreSQL client, familiarity with Amazon RDS parameter groups, and the openssl CLI. The rds.force_ssl parameter controls whether Amazon RDS rejects non-SSL connections, with defaults varying by PostgreSQL version.

Databricks Acquires Electric to Give AI Agents Their Own Local Postgres

Databricks has acquired Electric, a company known for its contributions to the Postgres ecosystem, including PGlite, a compact version of Postgres for WebAssembly environments. This acquisition includes a real-time synchronization engine that keeps local data copies consistent with a central cloud database. Electric's team will join Neon, a serverless Postgres company previously acquired by Databricks. The integration aims to enhance Lakebase, Databricks' managed Postgres offering, by using PGlite for local data management. PGlite's weekly downloads surged from approximately 1 million to 13 million over the past year, indicating growing developer interest in embedded database models. The acquisition reflects a shift towards decentralized data management for AI agents, with synchronization mechanisms becoming crucial. Databricks is reinforcing its investment in Neon, signaling a deeper relevance of its Postgres offerings. The increase in PGlite downloads suggests early developer interest in local-first database architectures, though widespread production adoption remains uncertain. The emergence of state, identity, payments, isolation, and sync as infrastructure components indicates a competitive landscape for the agent runtime layer, with Databricks strategically positioned in this race.

Google adds Gemini code conversion for PostgreSQL migrations

Google has enhanced its Database Migration Service with AI-assisted code conversion for PostgreSQL migrations from commercial databases. This feature addresses the challenge of converting stored procedures, triggers, and custom functions written in proprietary languages. The new workflow allows users to view original source code alongside suggested PostgreSQL PL/pgSQL output, enabling inline explanations, code editing, and validation before deployment. The service analyzes schema context across the migration project, considering table relationships and data types. It combines rule-based conversion with AI-generated suggestions and includes PostgreSQL syntax validation. The conversion process remains within the customer's Google Cloud project, adhering to security protocols. This feature aims to reduce the time for code conversion from months to days, allowing database specialists to focus on verification and application modifications. Once validated, the converted code can be applied to staging systems for testing before live migration.
