Autoscaling Lakebase Postgres

Choosing a database instance size without prior knowledge of the workload can lead to inefficiencies and excessive compute usage. Lakebase Postgres addresses this with an autoscaling feature that eliminates manual sizing, utilizing in-place VM resizing and a monitoring algorithm for CPU, memory, and working set size. Lakebase Postgres separates compute and storage layers, allowing independent resizing of compute nodes without affecting the database. The autoscaling algorithm relies on three signals: CPU load (cpuGoalCU), memory use (memGoalCU), and compute-cache working set size (lfcGoalCU). The CPU load is monitored every five seconds, aiming to maintain it at or below 90% capacity. Memory usage is tracked at two frequencies: overall memory every five seconds and Postgres-specific memory every 100 milliseconds, with a goal to keep usage below 75% of allocated RAM. The compute cache evaluates active data access efficiency, adjusting size based on workload. The working set is estimated using a modified HyperLogLog algorithm that records timestamps for page accesses, allowing for distinct page estimates over various time frames. The algorithm projects future working-set growth to allocate sufficient cache while capping it at 75% of RAM. Resizing the compute involves four components: the autoscaler-agent, vm-monitor, Kubernetes scheduler, and NeonVM. Scaling up occurs when any of the three goals indicate a need for more resources, while scaling down includes verification to ensure sufficient memory remains for operations. Timely adjustments in both directions are prioritized to minimize costs.

The AI memory crunch has reached the apps on your phone

Google will implement new memory usage regulations for Android applications starting in February 2027, due to a global RAM shortage. Apps exceeding the set memory limits may be throttled, terminated, or face reduced visibility on the Play Store. The memory thresholds vary based on device specifications, with specific limits for foreground, background, and bitmap memory usage. Non-compliance will result in penalties affecting app distribution and visibility. The memory crisis is attributed to increased demand from the AI data center industry, leading to rising RAM costs. The new limits will first apply to Pixel devices with Android 17, and other manufacturers are expected to follow. Additionally, by April 2027, all apps on the Play Store must support zero-tap credential restoration for users transitioning to new devices.

What is Android System Intelligence and what happens if you turn it off?

Android System Intelligence (ASI) is a component created by Google that enhances user experience on Android devices, particularly on Pixel phones, by supporting features like Live Caption, Now Playing, Smart Autorotate, and app predictions. ASI operates within Android's Private Compute Core, introduced in 2021, and utilizes machine learning without direct internet access, relying on Private Compute Services for cloud updates. It collects data such as crash logs and device identifiers for analytics, with users having the option to disable this data collection. ASI is not a standalone app but an infrastructure that supports various features, including music identification and smart notification actions. It requests extensive permissions for functionalities like smart predictions and contact suggestions, though not all features require all permissions. The privacy framework of ASI is designed to limit direct internet access, and users can view a Network Usage Log on Pixel devices. Disabling ASI is possible but does not remove it; it can be turned off under Settings > Apps. Reports indicate that essential phone functions remain intact even when ASI features are disabled, such as Now Playing and Live Caption. Google has not stated that disabling ASI will cause instability in the Android operating system. For troubleshooting ASI issues, Google recommends restarting the device, updating software, force-stopping the app, or clearing its cache or data. ASI has over 5 billion downloads on Google Play.

What to try when an Android app keeps crashing

Developers frequently update apps on the Google Play Store to improve user experience and fix bugs, with app crashes often resulting from problematic updates. To troubleshoot an app, users should check for updates in the Play Store. If no updates are available, users can access the app's settings by long-pressing the app icon or navigating through Settings > Apps. Users can clear the app's cache and force stop it to potentially resolve issues. If problems persist, uninstalling and reinstalling the app may be necessary, although this may result in loss of locally stored data unless cloud backup is enabled. Users can also clear the app's data directly from the App info page. Restarting the device and checking for system updates can also help resolve app crashes. Users can sideload older versions of apps from trusted sources like APKMirror if needed. Lastly, using the app's web version can serve as a temporary solution.

Best Ransomware Protection 2026: Tested and Ranked

Ransomware protection is best approached as a layered strategy rather than relying on a single solution. The effectiveness of software is significantly enhanced by maintaining a well-managed backup that is disconnected during an attack. Five tools were evaluated based on their default settings, focusing on behavioral detection, protected folders, file rollback, and real-time protection. 1. Norton 360: Rated as the best overall ransomware protection, it offers comprehensive features including behavioral monitoring, protected folders with dual alert modes, and 50 GB of cloud backup within a single subscription. It has a perfect score in advanced threat assessments. 2. Bitdefender: Recognized for its file rollback and remediation capabilities, it provides an effective "undo" feature that restores files, although this feature is turned off by default. 3. Avast One Free: The best free ransomware protection option, it includes a dedicated shield on the free Windows tier and has achieved a perfect score in advanced threat assessments. 4. NordVPN Threat Protection Pro: Best for blocking the delivery route of ransomware, it prevents downloads before encryption starts but cannot stop the process once it has begun. 5. McAfee: Best for protecting multiple devices simultaneously, it offers unlimited device coverage on most plans with integrated ransomware defense in its scanning engine. Modern ransomware protection software has shifted from signature matching to focusing on monitoring the behavior of processes interacting with files. The four essential layers of protection include behavioral monitoring, protected folders, automatic file rollback, and backup. Most users do not need a separate anti-ransomware product, as these features are typically included in main antivirus suites, with the key consideration being whether these features are activated. The rankings of the tools were based on whether the ransomware protection layer is enabled by default, the extent of file recovery when intervention occurs, and the frequency of false positives during normal use. - Norton 360: Best overall, with protection enabled by default and a perfect score in advanced threat testing. - Bitdefender: Best for file rollback, but the rollback feature is disabled by default. - Avast One Free: Best free option, with a perfect score in advanced threat assessments but lacks rollback capabilities. - NordVPN Threat Protection Pro: Effective at blocking malware downloads but does not provide rollback or backup features. - McAfee: Suitable for families with multiple devices, offering automatic backup of flagged files but lacks user-configurable protected folder options. The effectiveness of ransomware protection tools is primarily assessed through behavioral responses rather than library matching. Backup remains a critical layer of defense, functioning even when other layers fail.

Microsoft shares detailed guide for IT admins on saving massive internet data on Windows 11

Microsoft has released a guide for IT administrators focused on optimizing Windows deployments and reducing bandwidth usage through Windows Delivery Optimization configured via Microsoft Intune. Delivery Optimization uses a peer-to-peer sharing system, allowing devices to download content from each other instead of solely from Microsoft servers, which helps reduce internet strain for organizations with many Windows PCs. Administrators can create specific peer groups based on network topology and control bandwidth usage for downloads, with options to set different limits for business and off-hours. Microsoft also introduced Connected Cache, which stores frequently accessed content locally to further minimize bandwidth consumption. A statistic shared by Microsoft indicates that using Delivery Optimization can significantly reduce internet traffic, as a 1 GB update for 10,000 devices could otherwise generate 10 TB of internet traffic. The guide recommends starting with a small seeder ring of devices to populate peer caches before wider deployment. Microsoft provides specific policy settings for Delivery Optimization, including default and recommended values for settings such as download mode, peer selection, cache size, minimum file size for caching, cache age, and monthly upload data cap. Proper configuration of Delivery Optimization is suggested to benefit organizations managing large numbers of devices.
