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.

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.

Antivirus: Do you still need it?

Purchasing antivirus software is often seen as necessary but can be frustrating, especially with built-in security features available on most computers. Windows includes Microsoft Defender Antivirus, which has been independently tested and scored well for protection, performance, and usability. Mac users have XProtect for malware detection. Users should verify that their existing protection is enabled and up-to-date before considering a subscription. Antivirus programs combat various types of malware, using methods like signature scanning and heuristic analysis, but they are not infallible. Research on antivirus effectiveness varies, with scores reflecting different criteria and not universally applicable detection rates. Subscriptions may be worthwhile if they offer specific features, but users should be cautious about renewal prices and unnecessary multiple installations. Maintaining updated software and practicing good security habits are essential for protection. For everyday use, built-in protection is often sufficient unless additional benefits justify the cost of extra software.

How to check if your Android phone is still getting security updates

Smartphones may not receive crucial security updates, leaving them vulnerable to threats despite appearing to function well. Users can check their device's security status by navigating to Settings > About Phone to see the last security patch date. If it exceeds three to six months, the device may be nearing its support cutoff. Google Play system updates can also enhance security and should be checked via the Play Store. Manufacturers typically do not publicize end-of-life dates, but resources like endoflife.date can help users find this information. For example, the Samsung Galaxy S26 FE will receive updates until September 2033, while the Google Pixel 6 Pro will stop receiving support in October 2026. Google offers seven years of updates for Pixel 8 and newer models, while Samsung provides up to seven years for Galaxy S24 and Z Fold/Flip6 models. OnePlus offers four years of OS updates and up to six years of security patches. The European Union mandates a minimum of five years of software updates for new smartphones sold within the region starting June 2025. If a phone stops receiving updates, users should enable automatic app updates, avoid unverified apps, use two-factor authentication, back up data, and be cautious with public Wi-Fi. If the last security patch is over six months old or the device has surpassed its support cutoff, upgrading to a newer model is advisable.

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.

How I found tinnitus relief with free Android apps – and finally got some sleep

Two Android applications have been identified as helpful for tinnitus relief: one focuses on tonal therapy and the other on ambient sound generation. Both apps are free, with optional premium features. Tonal therapy involves using tailored sound frequencies to disrupt abnormal neural activity associated with tinnitus. Users must identify the pitch of their tinnitus, generate therapy tones, and play them in a staggered sequence. The Tonal Tinnitus Therapy app requires consistent use, with many users reporting significant symptom reduction over time. It offers a free version and a one-time purchase option for unlimited access. Recommended usage includes listening for at least four hours daily, starting with short sessions. The ambient noise generator app, such as Ambience: Sleep Sounds, creates soothing backgrounds to mask tinnitus sounds. It offers a variety of calming sounds and has both free and premium versions. Users can create personalized sound mixes to aid sleep, and reliance on the ambient generator may decrease as tonal therapy takes effect.
