Why Alternative App Stores Are Gaining Popularity Among Android Power Users

An alternative app store allows users to access apps and games not available on official platforms like the Google Play Store, including older versions, regional apps, and open-source options. Types of alternative app stores include third-party Android stores, open-source platforms, modified APK stores, regional stores, free app stores, and game-focused stores. Users explore these stores for a broader selection of apps, including those restricted by geography. Alternative app stores can provide apps that Google Play does not, such as regional apps and modified applications. When choosing an alternative app store, users should consider the platform’s reputation, app descriptions, update frequency, security measures, and source verification. Alternative app stores differ from Google Play by offering more flexibility and access to unique content, though security and developer support may vary. Modified apps are altered versions that may offer enhanced features. Alternative app stores are important for overcoming regional barriers and providing ad-free experiences. They host a variety of apps, including multiple versions of a single application, and typically feature user-friendly search functionalities. Comprehensive app information is often available, including version data and permissions. Some stores focus on open-source and independent apps. The legality of using alternative app stores depends on licensing and local laws, and they often feature apps not found on Google Play. Many alternative stores provide multiple app versions, and only reliable ones may offer faster updates.

How and why we built Managed PostgreSQL for AI workloads

The Nebius Managed PostgreSQL team developed a solution for AI workloads using CloudNativePG and Kubernetes, resulting in improved backup and restore times by transitioning from Barman to WAL-G, reducing a 1.5 TB backup duration from over a day to two hours. Since its launch in 2025, the service supports hundreds of production clusters and manages tens of tebibytes of data. Key features include high availability, point-in-time recovery, automated failover, compressed and encrypted backups, rapid restoration, connection pooling, and strict synchronous replication for zero data loss. Kubernetes and CloudNativePG were chosen for their advantages, including out-of-the-box features and open-source distribution. Each cloud project has a separate MK8s cluster for customer isolation and security. Persistent data is stored on fault-tolerant SSD drives, enabling swift instance migration during failures. Regular physical backups are archived, allowing restoration within a seven-day window with a single click. The transition from Barman to WAL-G addressed slow backup and restoration times and resource control limitations. With WAL-G, backups and restorations for a 1.5 TB cluster improved to two hours and one hour, respectively. PgBouncer was implemented to manage database connections effectively, reducing connection storms during peak AI workload traffic. Two vector search extensions, pgvector and pgvectorscale, are available to cater to different memory and dataset needs. Benchmarking showed that Nebius performs competitively with AWS at a lower cost. The infrastructure integrates cloud engineering principles with specialized expertise to meet AI workload demands.

DBtune autonomous optimization blows PostgreSQL bottlenecks away

DBtune, a startup based in Malmö/Lund, Sweden, was founded in 2020 by Dr. Luigi Nardi as a spin-off from Stanford University and Lund University. The company focuses on enhancing PostgreSQL's capabilities through autonomous database optimization technology and has raised .4 million in a seed round from various investors in July 2023, with support from the Wallenberg Foundation and Vinnova. DBtune's technology utilizes agentic AI for optimizing PostgreSQL databases by tuning server parameters, optimizing indexes, and monitoring autovacuum processes. The release of DBtune version 4.0 incorporates machine learning and AI to dynamically adjust server parameters and suggest optimal indexing strategies. The platform identifies and ranks potential index opportunities based on workload and provides recommendations for new indexes and maintenance of existing ones. A case study with Midwest Tape demonstrated a 10.8x performance improvement in database query runtime after employing DBtune for performance tuning. Benchmarking tests showed a transaction throughput increase of 87% during initial optimization, with a further 17% improvement on an already optimized system. Disk I/O activity was reduced by 43%, and WAL generation decreased by 23%. Dr. Nardi emphasizes the need for AI-driven optimization to manage the complexities of PostgreSQL databases and rising cloud costs, suggesting that significant code adaptations will be necessary for achieving fully autonomous PostgreSQL.

How Telangana’s MeeSeva migration to open source could make governments rethink software costs

In April 2026, Telangana's MeeSeva platform migrated from the Oracle database to the open-source PostgreSQL database after 15 years of reliance on Oracle. This transition aimed to reduce annual costs of approximately ₹10 crore associated with Oracle licensing and maintenance. The initiative began in 2023, and the migration was executed with less than four hours of downtime, processing around 80,000 transactions daily. The migration involved over 85 microservices, three Oracle servers, and 1,939 tables, with the process automated by the Ora2Pg tool, which handled 60-70% of the transition. The migration cost was below ₹10 lakh, and after the switch, MeeSeva processed nearly 200 million transactions without data loss. The new architecture includes automatic failover capabilities to minimize disruption.

VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.

How to supercharge your Windows 11 PC with this built-in automation tool

Windows 11 includes a Task Scheduler that automates repetitive tasks to enhance productivity. To set up a task, users should open Task Scheduler, select "Create Task," and fill in details under General, Triggers, Actions, Conditions, and Settings. It's important for laptop users to avoid scheduling tasks that run every five minutes to maintain low-power idle states. The "Run with highest privileges" option should be used cautiously for security reasons. Three recommended automations include: 1. Using WinGet to keep software updated with the command winget upgrade --all --silent --accept-package-agreements --accept-source-agreements --disable-interactivity, scheduled weekly. 2. Disabling unnecessary startup applications and launching them with a delayed logon trigger to reduce startup clutter. 3. Automating tasks with PowerShell for file transfers or system maintenance, ensuring they run during idle times or when connected to AC power. Windows also performs some maintenance tasks automatically, such as deleting temporary files and optimizing drives.
