Modernizing Nexus Repository: Moving Beyond OrientDB

Support for OrientDB in Sonatype Nexus Repository has been discontinued, and older versions of Nexus Repository (prior to 3.70.5) are built on an outdated architecture that presents high-severity vulnerabilities and cannot be fully patched. The recommended database for Nexus Repository is now PostgreSQL, which offers better performance and support for modern architectures. Users have two migration options: transition to Sonatype Nexus Repository Cloud, which is fully managed and eliminates database management, or migrate to PostgreSQL while maintaining a self-hosted environment, which requires ongoing maintenance and infrastructure ownership.

“We have discontinued SaRA”: Microsoft replaces its Windows 11 Recovery Assistant — here’s how to transition to Microsoft’s modern command-line replacement.

Microsoft has phased out the Support and Recovery Assistant (SaRA) utility with the March 2026 Security Update for Windows 11, replacing it with the new "Get Help" command-line tool. The SaRA was designed to troubleshoot and resolve common issues affecting Windows 11 and Microsoft 365 applications. Users are now encouraged to use the Get Help command-line tool, which offers enhanced functionality and security. To use the Get Help tool, users must download the files, extract them, and run specific commands in the Command Prompt. The tool addresses various issues, including Microsoft 365 activation challenges and Outlook profile errors.

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 fake Windows support website delivers password-stealing malware

A phishing campaign has been identified that uses a counterfeit Microsoft support website, microsoft-update[.]support, to trick users into downloading a malicious Windows update disguised as WindowsUpdate 1.0.0.msi. This file, created on April 4, 2026, appears legitimate but contains malware designed to steal sensitive information. The campaign targets French-speaking users, leveraging recent data breaches in France to create convincing scams. The malware, once executed, installs an Electron application that runs a Python interpreter, which then deploys various data theft tools. It employs two persistence mechanisms: modifying the Windows registry and creating a shortcut in the Startup folder. The malware connects to external sites for reconnaissance and data exfiltration, using domains like datawebsync-lvmv.onrender[.]com and store8.gofile[.]io. The malware's components have evaded detection by antivirus tools, with VirusTotal reporting zero detections for the main executable and its launcher. Users are advised to check their registry, remove suspicious files, change passwords, and run a full system scan if they suspect installation of the malicious update. Safe updating practices include using the built-in Windows update feature and being cautious of phishing attempts. Indicators of compromise include specific file hashes, domains associated with the phishing campaign, and file system artifacts related to the malware's installation.

How to Install XAPK Android Apps on a Windows PC

To install the Seekee app on a Windows PC, users can choose from several methods: 1. Using Bluestacks: This popular Android emulator simplifies the installation process. 2. Using MuMuPlayer: - Install MuMuPlayer on your Windows PC. - Import the XAPK file using the app installation feature. - Launch the app once installation is complete. 3. Manual Installation (if the XAPK does not open correctly): - Create a copy of the XAPK file. - Rename the extension from .xapk to .zip or use an archive tool to extract it. - Identify the package structure, looking for the Android/obb/com.example.app/ folder. - Install the main APK file in the emulator. - Copy the OBB data to the correct folder in the emulator's Android file system. - Launch the app after ensuring both the APK and OBB data are correctly positioned. XAPK installations may fail due to: - Incompatibility with the Android version. - Incomplete packages lacking OBB data or split APK components. - Mismatched package name and OBB folder. - Poorly repacked files. - Incompatible emulator profiles. A troubleshooting checklist includes: - Using BlueStacks with the Install APK option or drag-and-drop feature. - Exploring other emulators like MuMuPlayer. - Checking for app availability on Google Play within the emulator. - Ensuring OBB data is correctly placed. - Testing with different Android versions or emulator instances. - Re-downloading the file from a reliable source if suspected to be corrupted.

AI malware threatens Windows 11 security. Traditional antivirus can’t keep up

AI-powered fileless malware poses a significant challenge to Windows 11 security, as traditional antivirus solutions struggle to detect these advanced threats. This type of malware operates without traditional files and can execute malicious actions directly in memory, bypassing conventional detection methods. Vulnerabilities in applications like Excel and Outlook have been exploited, allowing harmful code execution through simple actions like opening a preview pane. The integration of AI features, such as Microsoft's Copilot, has also created new risks, leading to potential data leaks. To combat these threats, a multi-layered security approach that includes behavioral analysis and real-time monitoring is essential. Upgrading from Windows 11 Home to Windows 11 Pro provides additional security features to enhance defenses against malware.

I watched the first TV show ever based on a game and it made me realize: we’ve really got it good these days

The animated series Pac-Man, produced by Hanna-Barbera from 1982 to 1983, features characters such as Pac-Man, Ms. Pac-Man (Pepper), and Pac-Baby living in Pac-Village, which is governed by the Pac-President and protected by Super-Pac. The series includes antagonists like Mezmaron and a group of ghost monsters: Inky, Blinky, Pinky, Clyde, and Sue. Mezmaron seeks to capture Pac-Man for his knowledge of Power Pellets, which grow on Power Pellet Trees in the Power Pellet Forest. The show consists of 44 episodes over two seasons and often concludes with Pac-Man consuming the ghosts, who then return to Mezmaron in new ghost suits. The humor is aimed at children but lacks cleverness, and notable voice actors include Peter Cullen and Alan Lurie. The second season introduced a younger version of Pac-Man named PJ and increasingly bizarre plots.
