How PostgreSQL on Azure helps modernize legacy databases

Microsoft is enhancing PostgreSQL to establish it as a high-performance, scalable, and enterprise-ready open database platform, addressing the limitations of legacy systems like Oracle. Many Oracle customers face rising licensing costs, performance bottlenecks, and scalability issues, prompting them to consider migration. Apollo Hospitals successfully migrated from Oracle to Azure Database for PostgreSQL, achieving a 60% reduction in operational costs and a threefold improvement in system performance. Microsoft has introduced an AI-assisted migration tool to simplify the transition from Oracle to PostgreSQL, automating the conversion of schemas and application code. Azure Database for PostgreSQL offers high performance, scalability, and security, with features like v6-series compute SKUs and SSD v2 storage. Azure HorizonDB, a new cloud-native PostgreSQL service, supports extreme performance demands and is designed for real-time analytics. Microsoft is committed to enhancing PostgreSQL as an open-source database for enterprise workloads, enabling organizations to innovate and become more agile.

5 Things Linux Can Do That Windows 11 Can’t

Many users are switching from Microsoft's Windows operating system to Linux due to dissatisfaction with Windows 11's rollout and unpopular changes. Over half a million users have made the transition to Linux, which is known for its flexibility and reliability. Linux updates are optional, allowing users to choose when and what to update, with user-friendly options available for both graphical and command line interfaces. Unlike Windows, Linux does not come with bloatware, offering a streamlined experience where users can install only the applications they need. Linux provides extensive customization options, with various distributions available that can mimic the Windows interface or offer unique designs. It is also a robust choice for server management, allowing for continuous operation without frequent reboots and giving users control over update timing. Linux is compatible with a wide range of hardware, from new devices to older machines, and many distributions are designed to be lightweight. Additionally, Linux powers various devices, including the Steam Deck and Android smartphones, demonstrating its adaptability and efficiency in modern computing.

I wish more people knew about this free, open-source note-taking app

Megan Ellis from Android Authority explored productivity apps, highlighting the challenge of balancing features and user privacy. Notesnook emerged as a notable option, offering a free plan with multi-device syncing and user privacy. It includes features like a rich-text editor, reminders, and organizational tags without relying on third-party cloud services. Users can self-host if desired, and the app is open-source and compatible with major platforms. The free plan has limitations, such as compressed images, a cap on colors, tags, notebooks, and reminders, while paid plans offer additional features and higher limits. Notably, Notesnook has shown increased permissiveness in its offerings over time, contrasting with trends in the app market.

Netflix Automates RDS PostgreSQL to Aurora PostgreSQL Migration Across 400 Production Clusters

Netflix has developed an internal automation platform to migrate Amazon RDS for PostgreSQL databases to Amazon Aurora PostgreSQL, reducing operational risks and downtime for nearly 400 production clusters. The platform allows service teams to perform migrations through a self-service workflow while ensuring processes like replication validation and rollback safeguards are maintained. Database access is managed through a platform-managed layer using Envoy, which standardizes mutual TLS and abstracts database endpoints, enhancing security and efficiency. The migration process starts with creating an Aurora PostgreSQL cluster as a read replica of the source RDS instance, initialized from a storage snapshot and continuously replaying write-ahead log (WAL) records. Validation checks are performed to ensure the replica can handle peak write throughput before cutover. For change data capture workloads, the system coordinates the state of replication slots and pauses CDC consumers to prevent excessive WAL retention. The Enablement Applications team at Netflix successfully migrated databases for device certification and partner billing workflows, addressing issues like elevated replication lag due to inactive logical replication slots. As replication lag decreases, the system enters a controlled quiescence phase, adjusts security rules, and reboots the source RDS instance. Once all transactions are processed and the Aurora replica is ready, it is promoted to a writable cluster, and traffic is rerouted. Rollback capabilities are prioritized, allowing redirection back to the original RDS instance if validation checks fail or anomalies are detected post-promotion. This setup enables seamless restoration without redeployment, and CDC consumers can resume from recorded slot positions if needed.

Windows 11 tops market share as 10 faces extended farewell

Recent data from Statcounter indicates that Windows 11 has a market share of 72.57 percent, while Windows 10 holds 26.45 percent. Microsoft claims that Windows 11 has surpassed one billion users. Statcounter's data is collected from over 1.5 million websites and may be subject to revision. Microsoft will discontinue support for many versions of Windows 10 in October 2025, leading some organizations to consider Extended Security Updates (ESU), which can incur additional costs. Windows Server 2016 has a 20.3 percent share among monitored servers, and Windows 10 2016 LTSB accounts for 0.5 percent of Windows devices, making up 19.8 percent within the LTSC/LTSB category. The higher usage of LTSC/LTSB is attributed to special-purpose devices in consumer and retail sectors, which face stricter upgrade protocols.
Migrate PostgreSQL from DigitalOcean to AWS

Migrate PostgreSQL from DigitalOcean to AWS

The video tutorial explores two methods for migrating PostgreSQL databases from DigitalOcean to AWS. The first method uses native PostgreSQL CLI tools (pg_dump and pg_restore) for smaller databases. The second method employs AWS Database Migration Service (DMS) for larger databases, allowing for a seamless transition with minimal downtime. Key steps in the DMS process include creating replication instances, setting up endpoints, and configuring migration tasks. The video is divided into chapters covering both migration methods.
PoC Published for Microsoft Windows Flaw That Allows Low-Privileged Users to Force Irrecoverable BSODs

PoC Published for Microsoft Windows Flaw That Allows Low-Privileged Users to Force Irrecoverable BSODs

Security researchers have developed a working Proof of Concept (PoC) exploit for a vulnerability in the Windows kernel, identified as CVE-2026-2636, which allows low-privileged users to induce a Blue Screen of Death (BSoD), resulting in a Denial of Service. This vulnerability is linked to the Windows Common Log File System (CLFS) driver, specifically the CLFS.sys component, and arises from improper handling of invalid or special elements within CLFS (CWE-159). The PoC demonstrates that a non-administrative user can trigger the bug by executing a crafted ReadFile operation on a handle linked to an opened .blf log file without the expected I/O Request Packet (IRP) flags set. This leads to a critical inconsistency in the driver, causing Windows to invoke the kernel routine KeBugCheckEx, which results in a BSoD. The CVE-2026-2636 has a CVSS score of 5.5 (Medium) and poses a high impact on availability, allowing any authenticated user to crash the host reliably. Microsoft addressed this vulnerability in the September 2025 cumulative update, protecting systems running Windows 11 2024 LTSC and Windows Server 2025 by default. However, older or unpatched builds remain vulnerable. Organizations are advised to verify the deployment of the September 2025 updates, prioritize patching multi-user systems, and monitor for unusual spikes in BSoD events.
