Developer adoption trends show that 49% of respondents in the Stack Overflow 2024 Developer Survey use PostgreSQL, compared to 27% for SQL Server. The latest stable version of PostgreSQL is 18.4, released on May 14, 2026, while SQL Server 2025 (version 17.x) became generally available on November 18, 2025. PostgreSQL is free under a permissive license, while SQL Server's Enterprise Edition can cost upwards of ,123 per two-core pack, with an eight-core minimum. PostgreSQL supports various operating systems, including Linux, Windows, macOS, and BSD, while SQL Server operates on Windows and Linux. PostgreSQL uses PL/pgSQL as its primary procedural language, allowing for multiple procedural languages, whereas SQL Server uses T-SQL. PostgreSQL's JSONB type offers rich indexing, while SQL Server added native JSON support in its 2025 release. Both databases are capable of handling high transaction volumes, but PostgreSQL excels in read-heavy scenarios due to its multi-version concurrency control, while SQL Server's columnstore indexes provide advantages for analytical workloads. PostgreSQL supports tables up to 32 TB, while SQL Server can handle a maximum database size of 524 PB. SQL Server's high availability technology includes Always On Availability Groups, while PostgreSQL offers built-in streaming and logical replication. The security features of both databases meet enterprise standards, with PostgreSQL providing a transparent patching process and SQL Server integrating with Microsoft tools. Real-world usage examples include Stack Overflow using SQL Server, while Instagram and Reddit utilize PostgreSQL. Developer sentiment increasingly favors PostgreSQL for new projects, emphasizing flexibility and open-source solutions. For new startups or greenfield projects, PostgreSQL is recommended due to its zero license cost and compatibility. Existing Microsoft enterprises are advised to stick with SQL Server for its integration benefits. Migration from SQL Server to PostgreSQL is becoming common, with a structured approach required for successful transitions.

How We Test Antivirus and Security Software

Most software applications clearly indicate their functionality, but the effectiveness of antivirus utilities is often less tangible. PCMag rigorously evaluates antivirus products through comprehensive tests that validate their claims, including real-world malware samples and various protective measures. Each antivirus tool is assessed based on its on-demand scanner and real-time monitor capabilities. PCMag compiles fresh malware samples annually, analyzing them to ensure they are suitable for testing. The testing process includes evaluating malware-blocking capabilities and web-level protection against known malware-hosting sites. Phishing site detection is also tested using recent URLs, and antispam testing has been simplified due to the effectiveness of email providers. Performance impact tests have been discontinued as modern security suites show improved efficiency. Firewall protection is evaluated through program control, exploit defenses, and overall resilience against malware. Parental control features are tested for effectiveness in content filtering and monitoring. Ransomware protection is assessed by releasing real-world samples in a controlled environment. PCMag monitors independent antivirus lab tests from various organizations, including AV-Test, AV-Comparatives, SE Labs, MRG-Effitas, and AVLab, to inform their reviews. An aggregate testing score is calculated to summarize lab results. Testing methodologies do not include VPN evaluations, which are covered separately.

ADCS Now Generates Post-Quantum Certificates For Windows

Active Directory Certificate Services (ADCS) now supports the generation of post-quantum certificates, enhancing quantum-safe cryptography within Windows' secure connection protocols. Microsoft has integrated PQ TLS hybrid key exchange into the Windows Transport Layer Security (TLS) stack, providing protection against "Harvest Now, Decrypt Later" attacks. The PQ TLS hybrid key exchange combines traditional cryptographic methods with the NIST ML-KEM algorithm, offering three hybrid combinations: X25519MLKEM768, SecP256r1MLKEM768, and SecP384r1_MLKEM1024. This feature is available in preview via the Windows Insider Program and will be rolled out to Windows 11 and Windows Server. Additionally, Windows cryptography APIs now support composite ML-KEM and ML-DSA algorithms, which are NIST-approved standards for key exchange and digital signatures, enhancing security by requiring multiple components to be compromised. Microsoft emphasizes the importance of establishing new Certification Authorities (CAs) for implementing post-quantum certificate issuance, as existing CAs cannot be upgraded. The introduction of ML-DSA support within ADCS allows organizations to counter HNDL risks associated with long-lived data. Organizations are encouraged to inventory their use of public-key cryptography, prioritize systems protecting sensitive data, and test hybrid and composite approaches in non-production environments to facilitate a smooth transition to quantum-safe cryptography.

How mathematicians use Minecraft to calculate pi

Mathematicians Molly Lynch and Michael Weselcouch developed a method to approximate the value of pi (π) within the game Minecraft using a probabilistic darts technique. They constructed a circular structure with a radius of 11 blocks surrounded by a square and introduced random events using slimes, which move randomly. By counting the number of slimes killed within the circle compared to the total number killed, they calculated an approximation of π. During their test, they killed 619 slimes, with 508 inside the circular area, yielding an approximation of π ≈ 3.283. They noted that increasing the size of the square and the number of slimes could improve accuracy.

Meta faces court over Android tracking claims

Meta is facing a class action lawsuit for allegedly exploiting vulnerabilities in Android smartphones to track users' private information, linking browsing activity to Instagram and Facebook accounts. The lawsuit claims Meta unlawfully accessed and de-anonymized personal data of millions of Android users to enhance advertising profiling. A US District Court Judge ruled that most privacy-related claims in the lawsuit must proceed, stating that plaintiffs have plausibly alleged a significant intrusion upon their privacy. Meta is accused of exploiting an Android vulnerability to bypass security measures that isolate apps, allowing it to link browsing information to users' accounts. Although Meta has reportedly stopped using this tracking method, it successfully dismissed two claims related to unjust enrichment and the use of modified pixel code. Additionally, the lawsuit includes claims against Google for negligence, with one claim dismissed but another allowed to proceed. In response to regulatory pressures, Meta is introducing new features for parental supervision of teens on its platforms and plans to use AI to detect underage accounts.

Security updates Windows no longer require frequent reboots

Since early May 2026, a U.S. company has introduced Hotpatching technology for compatible devices, allowing security updates to be applied without a full system reboot. This technology replaces code fragments directly in the RAM of running processes, reducing the size of downloaded packages and enabling quicker implementation of critical patches. The update mechanism operates on a hybrid schedule with four base months requiring mandatory reboots for cumulative changes and eight hotpatching months focusing on in-memory security fixes. If extensive architectural changes are needed or if the software environment does not meet standards, the system defaults to a standard installation algorithm that requires a reboot. The technology is designed for corporate infrastructures with high operational demands and requires Windows 11 version 24H2 or later, specific editions, and enabled VBS virtualization protection.
