How PGSimCity Turns PostgreSQL Complexity Into a Virtual City 3D Simulation

Nikolay Samokhvalov has introduced PGSimCity, an open-source educational tool that visualizes PostgreSQL cluster mechanics in a 3D simulation accessible via web browsers. The tool represents PostgreSQL 18's internals as municipal districts, with components like shared_buffers and Write-Ahead Logging organized spatially. It separates rendering from state transitions to maintain architectural integrity. Backend developers can trace SQL statement lifecycles and simulate operational anomalies, such as memory restrictions leading to performance issues. The project has generated discussions on AI-assisted visualization and has received community feedback for improvements. PGSimCity includes PGlite for in-browser PostgreSQL execution and has a roadmap for future enhancements, with its codebase available on GitHub under the Apache-2.0 License.

Your Outdated Antivirus Might Be The Weakest Link

Antivirus software is essential for protecting devices from cyber threats, but simply installing it is not enough. Outdated antivirus software can lead to diminished protection, as it may not recognize new forms of malware, leaving devices vulnerable. The functionality of antivirus programs can also decline over time, limiting their effectiveness. Using outdated software increases the risk of data breaches, as cybercriminals often target these systems. Additionally, technical support for older versions may become unavailable, further exposing users to threats. Keeping antivirus software updated is crucial for maintaining security and accessing the full range of features.

Request for comment: Which way did you go when you reached the controversial ending of Mass Effect 3?

At the climax of Deus Ex: Human Revolution, players faced a choice between buttons that determined the game's ending, which drew mixed reactions. Six months later, Mass Effect 3 introduced a similar mechanic for its finale, leading to confusion among fans. The ending choices in Mass Effect 3 included: Destroy the Reapers, which eradicated all synthetic life; Control the Reapers, sacrificing Shepard's humanity; and Synthesize all life, merging organic and synthetic beings. Despite the release of a free extended cut DLC that added a fourth option to refuse to choose, many players remained dissatisfied with the endings. Over time, the fervor surrounding Mass Effect 3's ending has diminished, allowing fans to reflect on their choices with a calmer perspective.

Best Android Antivirus Apps 2026: Tested and Ranked

Bitdefender Mobile Security is rated as the best antivirus app for Android in 2026, achieving a 100% detection rate, 0.5% battery drain, and unobtrusive operation. The evaluation compared five antivirus applications on a Galaxy S26 Ultra, assessing detection rates, battery drain, scan speed, and permissions. Other notable antivirus apps include Norton 360 for Mobile, which is recognized for its features; Avast Mobile Security, known for its free version; McAfee Mobile Security, which excels in scam call and text filtering; and NordVPN Threat Protection, praised for web and Wi-Fi security. Most users may not need an antivirus app due to built-in protections like Google Play Protect, which automatically scans apps. However, specific scenarios warrant the installation of an antivirus app, such as sideloading apps, receiving scam texts and calls, assisting relatives, conducting banking and shopping on mobile, and using public Wi-Fi. The top five antivirus apps tested are: 1. Bitdefender Mobile Security: 100% detection, 0.5% battery drain, 31-second scan time. 2. Norton 360 for Mobile: 99.9% detection, 0.9% battery drain, 24-second scan time. 3. Avast Mobile Security: 99.9% detection, 0.7% battery drain, 26-second scan time. 4. McAfee Mobile Security: 99.78% detection, 1.0% battery drain, 34-second scan time. 5. NordVPN Threat Protection: 95.60% detection of web threats, 0.2% battery drain. Battery consumption varied, with NordVPN being the lightest and McAfee the heaviest. Permissions requested by each app also varied significantly, with Bitdefender requiring the most extensive permissions. Users are advised to check for legitimate antivirus apps by verifying the developer, installation count, update history, lab participation, and permission requests. Free antivirus apps like Avast and AVG offer effective protection but may lack some features of paid versions. Users should be cautious of fake security apps that mimic legitimate ones. If malware is suspected, users can run scans with Google Play Protect or other anti-malware apps and follow specific steps to remove malware if detected.

Do you really need an antivirus app on your Android?

The relevance of third-party antivirus software for mobile devices has declined as modern Android devices come with robust built-in security features. Google Play Protect blocks millions of harmful apps and conducts regular scans of installed apps. Android employs sandboxing technology to isolate applications, has a proactive permissions system, and provides regular security updates. While Android is not immune to malware, many threats now arise from social engineering tactics rather than technical vulnerabilities. Users face risks when connecting to public Wi-Fi networks, and malicious push notifications can mislead them. Third-party antivirus may be beneficial for users who sideload apps or notice signs of infection, but for most users, Google's Play Protect suffices. Older devices lacking updates are at higher risk, and while antivirus apps can provide additional protection, education and user vigilance are crucial for minimizing risk.

Best Free Antivirus Software 2026

Over the past decade, free antivirus software has significantly improved, now competing with paid security suites in malware protection. Independent testing from 2026 shows that Avast and AVG have achieved top scores in protection, performance, and usability. Microsoft Defender is a reliable option for Windows users who prefer not to install additional software.

Avast Free Antivirus received perfect scores of 6/6 in protection, performance, and usability from AV-TEST in May and June 2026, totaling 18 out of 18. AVG AntiVirus Free matched these scores and also received an Advanced+ rating from AV-Comparatives.

Bitdefender Antivirus Free is recognized for its lightweight protection, while Avira Free Security offers additional utilities. Malwarebytes Free is noted for its effectiveness in malware removal. Antivirus software is essential in the current cybersecurity landscape, which includes threats like ransomware and phishing attacks. In 2025, the FTC reported approximately .8 billion in fraud losses, a 25% increase from the previous year. While antivirus software cannot eliminate all forms of online fraud, it plays a crucial role in preventing attacks from escalating to data theft or system compromise. Users should be cautious of counterfeit antivirus software and are advised to download programs from official vendor websites. Free antivirus solutions generally focus on malware detection, while paid options offer additional services. For Windows 11 users, Avast Free Antivirus, AVG AntiVirus Free, and Microsoft Defender are recommended options based on 2026 evaluations.

You Can Use Your Old Android Phone As A Universal Remote – Here’s How

Repurposing an old Android phone can enhance home entertainment by connecting it to a smart TV through various methods. Both devices should be on the same Wi-Fi network to use mobile apps like Roku or Amazon's Fire TV remote app. If no official app is available, generic options like Universal TV Remote can be found on Google Play, although they may include ads. Bluetooth connectivity is also an option, exemplified by the Bluetooth Remote app. If Wi-Fi or Bluetooth is not feasible, an infrared (IR) blaster can be purchased to turn the smartphone into a universal remote without needing an internet connection. IR blasters connect via the USB-C port and communicate with the TV's built-in components. Various IR blasters are available, including standard models and more advanced versions that support voice commands. Most Wi-Fi and Bluetooth apps are free, while IR blasters are affordable and widely available.
