What a smart firewall does and why it matters on home Wi-Fi

Home Wi-Fi connects various devices and presents security risks, making firewalls important for network protection. A router firewall is built into the home router and protects all connected devices, while a software firewall operates on individual devices for additional security. Inbound traffic is data coming to a device, while outbound traffic is data leaving it; firewalls analyze this traffic to manage connections. Network security is critical as sensitive information is often accessed on devices used for leisure, and remote work increases data overlap. Firewalls can control network connections and filter unwanted traffic but cannot replace weak passwords or antivirus protection. To enhance home network security, users should secure router settings, keep routers updated, strengthen Wi-Fi access, check connected devices, and replace outdated routers. A comprehensive security strategy includes keeping software updated, using multifactor authentication, being cautious with links, and strengthening firewalls with antivirus protection. Protecting valuable data is essential, and understanding ransomware risks is crucial. The 3-2-1 backup strategy involves maintaining three copies of data on two different storage types, with one copy offsite. Regularly testing backups and knowing how to respond to ransomware incidents are also important.

“Now includes TETRIS for Windows!” The story behind Microsoft’s 1990s last-minute sticker gamble

Microsoft faced challenges during the launch of the Microsoft Entertainment Pack, particularly regarding the packaging and licensing of Tetris. Due to ongoing negotiations for the licensing rights, the initial packaging did not include any reference to Tetris, leading to the decision to use a bright red sticker stating "Now Includes TETRIS for Windows!" once the licensing agreement was secured just before the product launch. This last-minute addition transformed the marketing approach into a success, and the product was later branded as Microsoft Entertainment Pack 1. The stickered version of the pack has since become a sought-after collectible.

How to Protect Against Ransomware: 13 Steps [2026]

Global ransomware attacks increased by 0.8% quarter-over-quarter in Q2 2026. The group Qilin has 279 confirmed victims, maintaining its position as the leading threat actor for four consecutive quarters. The rival group The Gentlemen saw a 62% increase in victims, reaching 269. Checkpoint Research's report indicates a shift in the ransomware landscape, challenging the narrative of declining attacks. IBM's analysis shows breaches within supply chains and third-party vendors have quadrupled over the past five years. Effective ransomware protection requires administrative access to endpoints, firewalls, and backup systems, along with specific software versions and tools. The 3-2-1-1-0 backup strategy is recommended, emphasizing offline, immutable backups. Organizations should implement multi-factor authentication (MFA) across all access points and actively patch known vulnerabilities. Network segmentation is crucial to limit ransomware spread, and canary files can provide early warnings of attacks. Regular phishing simulations and a well-documented incident response plan are essential for preparedness.

Migrate Vaultwarden to PostgreSQL: Scale for Teams [2026]

Self-hosting Vaultwarden with SQLite can lead to performance issues as the user base grows, particularly due to SQLite's limitations with concurrent writes. Transitioning to PostgreSQL allows for better performance, multi-user support, and enhanced data durability. PostgreSQL supports concurrent connections and row-level locking, making it more suitable for team environments. To migrate from SQLite to PostgreSQL, certain prerequisites must be met, including having an existing Vaultwarden deployment, Docker Engine, a PostgreSQL server, and pgloader installed. The migration process involves backing up existing data, deploying a PostgreSQL container, updating configuration files, and using pgloader to transfer data. A VPS with 2 vCPU and 4GB RAM can support up to 50 users, with larger teams requiring more resources. PostgreSQL also allows for the creation of organizations for shared vault access and the configuration of group policies for security. Regular backups and performance tuning are necessary to maintain optimal operation. Common pitfalls during migration include not stopping the Vaultwarden container before migration, failing to encode special characters in the database password, and neglecting to back up data. Troubleshooting may involve checking connection strings and ensuring the PostgreSQL container is healthy. Advanced configurations can enhance performance and functionality, and understanding the differences between Vaultwarden and Bitwarden's official self-hosted server can aid in decision-making.

Your Windows PC has a secretly useful backup tool – here’s how to access it

Windows Backup is a built-in feature in Windows that allows users to back up specific folders and files, as well as create a complete system image. Backups can be directed to various media, including CDs, DVDs, external hard drives, or network locations, and users can schedule backups to run at regular intervals. However, Windows Backup has been deprecated by Microsoft and is no longer supported or updated, which may lead to occasional issues. A newer tool also named Windows Backup exists, designed for backing up and restoring specific files and settings for PC transitions. Users should prepare their storage media, typically external drives with 16GB to 32GB of space, before using the older Windows Backup. Restoration options include returning files to their original location or a different one, depending on the situation. Despite its deprecated status, Windows Backup remains functional and is considered a valuable tool for users seeking a built-in backup solution.

I tried 3 Windows laptops with Qualcomm chipsets this year – and found 3 glaring issues

Last year, Microsoft introduced Snapdragon-powered Copilot+ PCs, prompting the purchase of a Surface Pro 11, which became essential for daily tasks. This led to acquiring additional devices, including a Surface Laptop and a Dell XPS 13, both with Snapdragon X Elite chips. Despite effective marketing, businesses remain cautious about these devices. Windows on Arm has improved for Office applications and web services, with devices maintaining cool temperatures and long battery life. However, there are limitations: backup software may not work effectively on Arm devices, as external drives are inaccessible during recovery, necessitating workarounds like network or cloud storage. Installing Linux on Snapdragon-powered PCs is challenging due to a lack of compatible installation images, making Intel-based PCs more practical for work tasks. Additionally, Arm-based devices have performance constraints for gaming, with Snapdragon processors unable to compete with dedicated GPUs, making high-performance gaming unfeasible.
