Microsoft Wants to Protect Your Linux Desktop with Defender

Microsoft has expanded its Defender security software to Linux desktop environments, currently in public preview. Microsoft Defender for Endpoint is designed for organizations using Linux workstations and aims to enhance security for developers who interact with sensitive resources. Key features include real-time antivirus protection, endpoint detection and response, threat investigation, vulnerability management, and centralized security monitoring. The software uses the same deployment packages and installation methods as those for Linux servers, supporting distributions like Ubuntu LTS, Debian, Fedora, Red Hat Enterprise Linux, openSUSE Leap, SUSE Linux Enterprise, Rocky Linux, and AlmaLinux. Compatibility with desktop environments is based on the underlying distribution and kernel. The software identifies devices by assessing operating system metadata, and if it cannot classify a machine as a workstation, it defaults to identifying it as a server. This development follows the introduction of Defender for Linux servers in 2020. Organizations need a Microsoft Defender for Endpoint subscription and must meet Linux system requirements to use the software.

Windows 11 24H2 hits end of updates Oct. 13: What you should do now

Windows 11 version 24H2 for Home and Pro systems will stop receiving security updates on October 13, 2026. After this date, these editions will not receive any updates or technical support, although they will still boot. Windows 11 Enterprise, Education, IoT Enterprise, and Enterprise multi-session editions will continue to receive support until October 12, 2027. Organizations are advised to verify their systems' versions and editions, especially for those without endpoint management systems. Windows 11 25H2 and 26H2 are available as upgrade options, with 25H2 supported until October 12, 2027, and 26H2 supported until October 10, 2028, for Home and Pro editions. The rollout of 26H2 will be phased, and safeguard holds may be implemented if compatibility issues are detected. Unmanaged Home and Pro devices on 24H2 will automatically receive 25H2, while managed devices may require IT intervention. Regular monitoring and proactive management of Windows versions are necessary to ensure compliance and avoid future deadlines.

Query Plan Hints in PostgreSQL 19: A New Postgres Feature You Will Probably Never Need

PostgreSQL 19 features an advanced query planner that utilizes table statistics from pg_statistic, gathered during the ANALYZE process, to generate and evaluate potential query plans based on their costs. The planner assesses various configurations, especially in complex joins, to select the most efficient option. Instances of poor planning are treated as bugs and addressed promptly. To improve query performance, users are advised to refresh statistics with ANALYZE, use CREATE STATISTICS for column correlations, modify indexes, and adjust memory settings. In cases where the query cannot be altered, providing planner advice may be necessary, particularly when the planner misestimates the output of PL/pgSQL functions or other custom functions, leading to inefficient query execution.

From searching to doing: Building a faster, more streamlined Windows Search

Search functionality is essential for navigating Windows PCs, and enhancements to the Windows Search Box were initiated in July to declutter the interface and improve user control. A new Windows Search experience powered by WinUI 3 will be available on the taskbar for Windows Insiders starting October 7, focusing on speed and efficiency with a streamlined design. The user interface has been simplified into a single list format, and improvements include better matching for typos and synonyms. Future updates will introduce inline previews, richer file details, and the ability to filter results. Inline actions will allow users to complete tasks directly from the search interface, such as toggling settings and managing their workspace. There are plans to integrate the new search experience into the Start menu and enhance its capabilities further. The new search experience is rolling out to Windows Insiders in the Experimental channel, with English as the initial supported language. Feedback can be shared through the Feedback Hub.

Someone Used AI to Make Minecraft Playable Inside Twitter With Working Multiplayer, and Immediately Sold Sponsorships via Crypto

Minecraft is now playable within posts on X (formerly Twitter) through a project called "Tweetcraft," developed by user jaivin using AI technology. Tweetcraft allows users to create a shared Minecraft world and post a link for others to join in real-time multiplayer sessions. Jaivin has also introduced in-game sponsorship opportunities, enabling players to purchase ad placements with cryptocurrency. The project operates without official authorization from Mojang or Microsoft, and jaivin claims it uses none of Minecraft's assets. The launch post has garnered over 7.4 million views, raising potential legal concerns. The community's response includes both enthusiasm and apprehension regarding possible legal challenges. Additionally, October has seen the emergence of browser-based versions of other popular games, highlighting the rapid innovation in AI-generated gaming content.

How to Integrate Unity ARCore Geospatial Into a Native Android App

The integration of AR capabilities into an app using Unity involves several steps. Initially, a Geospatial sample project is created in Unity, starting as a 3D project and switching the platform to Android. Key steps include downloading and importing the Cesium and ARCore Extensions packages, setting project settings for Android, enabling Google ARCore, and configuring API keys. For 3D model integration, a model is selected from the Unity Store, positioned correctly on the map using AR Geospatial Creator Anchor, and adjustments are made for visibility. Animation is added through an Animator Controller, and potential build issues may require adjustments in Unity preferences. When importing Unity as a library into an Android project, the minSdk version must align with Unity settings, and resolved libraries should be deleted to avoid complications. The unityLibrary is included in the project’s settings.gradle file, and modifications to build.gradle files may be necessary to resolve NDK visibility issues. A missing string resource can cause crashes, which can be fixed by adding a string to strings.xml.

Google’s Android Security State Libraries Enable Component-Level Security Verification

Google has launched AndroidX Security State libraries, enabling applications to verify security patch status at a granular level for individual components. This allows developers to conduct precise security verifications tailored to their applications' needs. The libraries categorize security patch levels into Device SPL, Published SPL, and Available SPL, providing enhanced visibility into device security. Functions such as queryAllAvailableUpdates() and areCvesPatched() help identify pending updates and check CVE status. The Security State Provider library standardizes communication for update notifications among OEMs.

OM SDK sandbox cuts Android ad session start to 11 ms, IAB Tech Lab says

IAB Tech Lab has released version 1.6.10 of its Open Measurement SDK for Android, introducing the ability for verification scripts for native ads to run within Android's Jetpack JavaScriptEngine instead of the traditional WebView. This update, effective from October 1, 2026, allows for a significant reduction in verification check initiation time, with the sandbox environment taking approximately 11 milliseconds compared to 268 milliseconds in the WebView. Applications that do not implement this new feature will continue to function as before, and HTML-based ads are not included in this update. The JavaScriptEngine library allows JavaScript evaluation without a WebView, reducing resource consumption and enabling compatibility with background services. The adoption process for this feature involves updating to OM SDK Android 1.6.10 or later, integrating the androidx.javascriptengine dependency, and maintaining the sandbox throughout the app's lifecycle.

Chrome for Android has windows, and they’re better than tab groups for multitasking

Chrome for Android supports the use of windows, allowing users to open multiple windows, each with its own tabs while sharing bookmarks and settings. Users can open an unlimited number of windows, which appear distinctly in Android's Recents screen. To open a new window on slab-style phones, users activate split-screen mode, tap the three-dot menu icon, and select "New window." For foldable phones, users can skip the split-screen step. Tabs can be moved between windows using the three-dot menu icon. All open windows can be managed through the Recents multitasking screen, where users can assign names or close them. This window functionality enhances multitasking and organization, making mobile browsing more akin to a desktop experience. Other browsers like Samsung Internet and Microsoft Edge have adopted similar features, while Firefox has not.
