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.

Fake dating apps are being used to target Android users: How the new cyber scam works

India's cybercrime authorities have warned about the misuse of dating and adult-themed advertisements on social media platforms like Instagram and Facebook, which are being exploited by criminals to distribute malicious Android applications. These ads redirect users to external websites where they are prompted to download APK files, bypassing security measures of trusted app stores. The Indian Cybercrime Coordination Centre (I4C) has identified several malicious applications, including Night Play, Reloop, Kyss, Vimo, Rivo, Nexo, and Vixa, and cautions against installing unfamiliar applications promoted through unsolicited ads. These apps may request sensitive permissions, such as access to SMS messages, contacts, photos, device storage, and Accessibility Services, which can allow fraudsters to access valuable information. Compromised devices can lead to financial fraud by intercepting OTPs and other verification details. The I4C recommends using trusted app stores, keeping Google Play Protect active, reviewing app permissions, and being cautious with social media ads. If a suspicious app is installed, users should restart their phone in Safe Mode to uninstall it, disable its permissions if necessary, and consider a factory reset if removal fails. Users who suspect fraud are encouraged to report incidents promptly.

Beware of fake Indeed interview apps used to install spyware

Scammers are exploiting the Indeed platform to target job seekers by using counterfeit Android "interview" applications. Users in the UK and Brazil reported being instructed by supposed employers to download fraudulent apps like MyInterview, which compromised their devices. These scammers post fake job listings and prompt applicants to install apps that mimic Indeed's login page and establish a VPN connection. The malicious apps, classified as Trojan.Droppers, can install additional untrusted software and gain control over devices, complicating uninstallation efforts. Indeed confirmed that their interview process does not require downloading any separate app and warned job seekers against such scams. Indicators of compromise include specific MD5 hashes and package names associated with the Trojan droppers and dropped malware payloads.

Galaxy Store Will Start Hiding Unverified Android Apps in September

Samsung has alerted developers using the Galaxy Store about upcoming changes due to Google's new Android Developer Verification (ADV) rules, which will take effect on September 30, 2026. Developers in Brazil, Indonesia, Singapore, and Thailand must complete the verification process to avoid having their unverified apps removed from the Galaxy Store. The ADV process requires developers to authenticate their identities and register package names and signing certificates. Apps that are not verified will be hidden from search results and listings, affecting their visibility. Users may face difficulties reinstalling or updating existing apps until developers complete the verification, although previously installed apps will continue to function. Samsung is indicating the status of app binaries in the Seller Portal and will restrict new registrations and updates lacking ADV approval starting in September. Sideloading will still be possible for certain apps and through an advanced installation flow, while ADB installations will remain unchanged. The initial rollout is limited to specific countries, with a global expansion expected in 2027. Developers are encouraged to act quickly to maintain app visibility.

Migrate Vaultwarden to PostgreSQL: Scale for Teams [2026]

Self-hosting Vaultwarden with SQLite can lead to performance issues as the user base grows, particularly due to SQLite's limitations with concurrent writes. Transitioning to PostgreSQL allows for better performance, multi-user support, and enhanced data durability. PostgreSQL supports concurrent connections and row-level locking, making it more suitable for team environments. To migrate from SQLite to PostgreSQL, certain prerequisites must be met, including having an existing Vaultwarden deployment, Docker Engine, a PostgreSQL server, and pgloader installed. The migration process involves backing up existing data, deploying a PostgreSQL container, updating configuration files, and using pgloader to transfer data. A VPS with 2 vCPU and 4GB RAM can support up to 50 users, with larger teams requiring more resources. PostgreSQL also allows for the creation of organizations for shared vault access and the configuration of group policies for security. Regular backups and performance tuning are necessary to maintain optimal operation. Common pitfalls during migration include not stopping the Vaultwarden container before migration, failing to encode special characters in the database password, and neglecting to back up data. Troubleshooting may involve checking connection strings and ensuring the PostgreSQL container is healthy. Advanced configurations can enhance performance and functionality, and understanding the differences between Vaultwarden and Bitwarden's official self-hosted server can aid in decision-making.

Microsoft highlights useful Microsoft Account feature Windows 11 users could miss

Many readers and developers express dissatisfaction with the Microsoft Account requirement for Windows 11. Microsoft advises users to unlink or remove devices from their Microsoft Account, especially after upgrading or retiring old machines, as the Microsoft Store limits accounts to 10 devices. Users can manage their devices through the Microsoft Account online portal, and unlinking or removing a device frees up space for new ones. Unlinking does not delete the account, and removing a Windows user account from a PC only clears sign-in information from that device. Microsoft recommends backing up data and resetting a device before removal when selling or donating. Users should periodically review their linked devices and can designate trusted devices to streamline sign-ins, while also implementing additional security measures like two-step verification.

Google’s Android Sideloading Rules Take Shape: Installation Won’t Be Blocked, but Apps from Unverified Developers Will Be Intercepted

Google has introduced a new app installation framework called "Advanced Flow," which allows sideloading of apps on Android devices but requires developers to complete real-name verification. Applications signed by unverified developers will be flagged during installation. Users can still sideload apps, but must enable "Developer Options" and acknowledge risks associated with unverified software. A 24-hour waiting period is imposed after enabling Developer Options, with options for permanent or temporary toggling. Google plans to enforce these developer verification requirements starting September 30 in Brazil, Indonesia, Singapore, and Thailand, with a global rollout expected by 2027. ADB installations are not subject to these restrictions.
