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.

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.

The Best Antivirus Software of 2026: Do You Even Need It?

Antivirus software is evolving as operating systems like Windows 11 and macOS now include robust built-in security measures, reducing the necessity for standalone antivirus solutions. Windows 11 features Microsoft Defender Antivirus, while Macs and Android devices have their own built-in protections. Independent tests show that Microsoft Defender achieved a perfect score in AV-TEST's April 2026 evaluation and performed well in AV-Comparatives' tests. Key antivirus solutions in 2026 include: - Bitdefender Total Security for individuals seeking paid protection. - Microsoft Defender for Windows users wanting free protection. - Norton 360 Deluxe for families, offering comprehensive features. - Avast One as a free third-party protection option. - Bitdefender Antivirus for Mac users seeking extra protection. - Google Play Protect for Android users. Choosing the right antivirus solution depends on factors like device type and user habits. While Microsoft Defender offers solid protection, users seeking comprehensive security may prefer Bitdefender or Norton 360 Deluxe. Avast One is a viable free alternative. Antivirus software cannot prevent all threats, emphasizing the importance of good security habits, such as keeping systems updated and using strong passwords. Modern antivirus solutions are designed to minimize impact on system performance.

Your old phone isn’t useless: 4 smart ways to get more life out of it

Phone upgrades often lead to replacing devices every couple of years, but old phones still hold value. Users typically choose to deal with their old phones in the following ways: 26% sell or trade it in, 26% hand it down to family or friends, 42% turn it into a dedicated gadget, and 5% let it sit in a drawer. Old phones can be kept as second devices for personal and work separation, used as an Android Auto display, or serve as a backup phone for emergencies. They can also be repurposed into gadgets like dash cams, security cameras, music players, e-readers, universal remotes, or PC companions. Additionally, they can replace webcams, act as second screens, or provide portable storage. If repurposing isn’t appealing, selling the phone is a practical option, with a strong market for used phones on platforms like SellCell, Swappa, eBay, or Facebook Marketplace. Trading it in may yield better benefits, especially with retailer promotions, and donating it to charity is another option.

Microsoft Enables Windows Settings Backup by Default

Microsoft has announced that Windows settings backup will now be enabled by default on eligible Windows 11 version 26H2 devices. This feature, previously known as Windows Backup for Organizations, automatically preserves users’ Windows settings and Microsoft Store app lists, facilitating restoration after device resets, replacements, or reimages. The change aims to minimize disruptions during device recovery and ensures more devices have recovery data readily available. Administrators will still control the restore process, which requires explicit configuration. The default-on behavior applies only to Windows 11 version 26H2 or later, devices with the backup policy in a “Not Configured” state, and excludes certain environments. Administrators can disable the backup feature if necessary.
