Microsoft has acknowledged that the April 2026 security updates have disrupted the functionality of various third-party backup applications using the psmounterex.sys driver, raising concerns among users. The issue primarily affects software leveraging the Volume Shadow Copy Service (VSS) snapshots, leading to failures due to VSS service timeouts. Notable impacted products include Macrium Reflect, Acronis Cyber Protect Cloud, UrBackup Server, and NinjaOne Backup, used on Windows 11, Windows Server, and Windows 10 devices. Disruptions can manifest as failures to mount backup image files, errors or timeouts when browsing or restoring from backup images, and error messages related to VSS timeouts. Microsoft updated its support documentation to clarify that the April updates included a security hardening change that added psmounterex.sys to the vulnerable driver blocklist to protect against a high-severity buffer overflow vulnerability (CVE-2023-43896). Affected users are advised to upgrade to newer application versions with updated drivers and not to uninstall or pause the security update. Users can check if the Microsoft Vulnerable Driver Blocklist is blocking a driver by looking for Event ID 3077 in the Code Integrity Operational log. Additionally, Microsoft has alerted users that some Windows Server 2025 devices may boot into BitLocker recovery mode after installing the KB5082063 update and has issued out-of-band updates to address installation failures and restart loops affecting Windows Server systems after the April 2026 updates.

The KB5083769 security update released in April 2026 has disrupted the functionality of various third-party backup applications on Windows 11 versions 24H2 and 25H2, primarily due to issues with the Volume Shadow Copy Service (VSS). Affected applications include Acronis Cyber Protect Cloud, Macrium Reflect, NinjaOne Backup, and UrBackup Server. Users have reported receiving an error message indicating that backups have failed due to VSS timeouts. Acronis has acknowledged the issue, stating it affects both Windows 11 Pro and Home editions, and warns of potential broader system issues. A temporary solution involves uninstalling the KB5083769 update or pausing Windows updates. Additionally, Microsoft has issued out-of-band updates for critical issues affecting Windows Server systems and warned that some Windows Server 2025 devices may encounter BitLocker recovery prompts after installing the KB5082063 update.

Samsung plans to retire its proprietary messaging app by July 2026, leading many Android users to rely on Google Messages. Major carriers like AT&T have stopped supporting their own messaging apps, potentially creating a monopoly. Alternative SMS-enabled apps include: - Pulse SMS: Syncs across devices, offers password-protected cloud backups, and has end-to-end encryption for stored conversations. It has a 3.6-star rating on Google Play. - Chomp SMS: Highly customizable with features like scheduled messages and block lists. It remains free with ads, but some users find the customization options complex. - Handcent Next SMS: Incorporates AI for features like text extraction and grammar checks. It has over one million downloads and a 4.4-star rating, but requests a high number of permissions. - Textra SMS: Offers faster performance and extensive customization, aiming to replace default messaging apps. It follows a "free forever" model but lacks cross-device functionality and encryption. The selection of these alternatives was based on Google Play ratings above 3.5 stars, a minimum of 50,000 user reviews, and recent updates.

Efforts to merge storage roles into a single solution are ongoing, particularly with Amazon S3's durability and cost-effectiveness. In PostgreSQL, achieving a durable commit requires flushing the Write-Ahead Log (WAL) before signaling transaction completion, which can take tens of microseconds on high-performance NVMe drives but extend to milliseconds on slower storage. This latency impacts Online Transaction Processing (OLTP) systems and user response times. Benchmark studies show that systems with faster local storage outperform those with slower alternatives as workloads exceed memory capacity. The fsync operation in PostgreSQL is a commitment rather than a simple write, with enterprise-grade SSDs performing better due to power-loss protection. Read operations also face challenges, as PostgreSQL's need for small, latency-sensitive reads conflicts with S3's design for larger, higher-latency requests. As the working set exceeds memory, storage latency becomes a critical performance factor. Modern managed PostgreSQL systems typically do not place object storage in the critical commit path, instead maintaining a fast log or cache close to the database while relegating colder data to remote storage. Recent PostgreSQL developments, such as asynchronous I/O support in version 18, aim to leverage fast storage more effectively. S3 is valuable for tasks like WAL archiving and backups, but these should be kept separate from the commit path to avoid resource contention. The solution involves using both NVMe and S3, with fast storage managing commits and cache misses, while object storage handles archives and backups. PostgreSQL performs best when hot and cold storage functions are clearly delineated.

88% of U.S. adults with laptops have taken measures against potential malware in the past year. Among those who encountered malware, 60% manually deleted the file or closed the offending website, while 35% initiated an anti-malware scan. Recommended steps for responding to a malware infection include disconnecting the device from Wi-Fi, connecting to a guest network, using antivirus software to remove the threat, and performing a factory reset or wiping the hard drive if necessary. It is advised to run at least two different antivirus programs to ensure comprehensive protection and to avoid restoring data from backups that may harbor malware.

Norton, owned by Gen Digital, provides antivirus software, VPN services, and identity theft monitoring to protect users from cyber threats such as malware and phishing attacks. The company emphasizes subscription-based revenue through Norton 360, which bundles various security features, ensuring predictable cash flow. Norton competes with other antivirus brands like McAfee and Bitdefender, maintaining a strong market share in North America due to its established brand trust. The demand for cybersecurity tools is driven by rising cyber threats, including ransomware attacks and increased remote work, which necessitate robust online protection. Gen Digital is investing in AI-driven threat detection and expanding its offerings to address evolving security needs. However, Norton faces challenges from free alternatives, potential privacy concerns, and macroeconomic pressures that could affect consumer spending on security products.

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.
