Improve PostgreSQL performance using the pgstattuple extension

PostgreSQL is an open-source relational database management system known for its extensibility, which allows developers to enhance its capabilities through various extensions and plugins. The pgstattuple extension provides detailed statistics at the tuple level from PostgreSQL tables and indexes, revealing key metrics such as the number of live tuples, dead tuples, average length of live tuples, total free space, and percentages of free space and dead tuples. These metrics help database administrators identify potential health and performance issues, such as excessive table bloat or index fragmentation. Both Amazon Aurora and Amazon RDS support the pgstattuple extension, which can be activated using the command CREATE EXTENSION pgstattuple;. Functions like pgstattuple(relation) and pgstatindex(index) can be used to analyze physical storage and index statistics. Bloat occurs when unused space is left behind after UPDATE and DELETE operations, and the autovacuum process in PostgreSQL automates the cleanup of dead tuples. However, if autovacuum fails, manual intervention may be necessary. Regular monitoring of bloat is essential for maintaining performance, and metrics from pgstattuple can help optimize autovacuum settings. The pg_cron extension can automate VACUUM operations to manage bloat proactively. Index bloat can also be detected using pgstatindex, and significantly bloated indexes can be rebuilt using REINDEX or pg_repack. Best practices for using pgstattuple include estimating bloat with check_postgres, analyzing physical storage, monitoring dead_tuple_percent, and avoiding interference on highly active tables.

Beware new Google ‘yellow warning’ that saves you from costly nightmare

Google has introduced a yellow warning banner in the Google Play Store to alert Android users about apps that are frequently uninstalled. This banner indicates that an app may not be meeting user expectations and could be due to poor functionality, excessive advertisements, or inflated costs. Additionally, Google has implemented two other notifications: one indicating lower user engagement with an app and another showing fewer users compared to other apps. These features aim to help users make more informed app choices and avoid potentially harmful applications. Google Play Protect is also available to scan downloaded apps for security, including those from outside the Play Store. Users can enable settings to improve harmful app detection, enhancing overall safety in the app ecosystem.

Google’s Play Store Warning—Do Not Update This Setting

A sophisticated trojan named TsarBot is targeting over 750 legitimate banking and shopping applications on Android devices. It overlays a counterfeit login screen on real apps to capture user credentials. TsarBot is believed to have Russian origins and can remotely control the device's screen, simulating user interactions and capturing device lock credentials through a deceptive lock screen. The trojan is typically installed from phishing websites, where a dropper application delivers the TsarBot APK file. Once installed, it disguises itself as the Google Play Services app and urges users to enable Accessibility services. Users are advised to avoid installing apps from outside the Google Play Store, ensure Play Protect is enabled, and only enable Accessibility Services when necessary to mitigate risks.

Watch Out for This Info-Stealing Malware on Windows

A new malware strain called CoffeeLoader has been identified, posing a significant risk to gamers by masquerading as a legitimate ASUS utility, specifically the Armoury Crate software. Once it infiltrates a system, it deploys the Rhadamanthys infostealer, which can extract sensitive information such as credentials from web browsers, email clients, cryptocurrency wallets, and password managers. CoffeeLoader evades detection by most security tools by operating on the GPU instead of the CPU and using advanced techniques like call stack spoofing, sleep obfuscation, and exploiting Windows fibers. To protect against CoffeeLoader, users should exercise caution when downloading software, navigate directly to official websites, avoid suspicious links, and adhere to basic cybersecurity practices. If infection is suspected, users should disconnect from the internet, reboot in safe mode, delete temporary files, and check Task Manager for unusual activity. Employing a reliable malware scanner can help identify and eliminate infections.

Here’s why you should reinstall Windows 11 every two months – no, I’m not kidding

Windows has evolved through various versions, creating a strong connection among users. Bugs can arise from updates, driver issues, or upgrades, and it is often advised to avoid upgrades in favor of fresh installations. Corrupted registry files and mislabelled directories can lead to resource consumption by background programs. A dual-storage drive system is recommended, designating a fast drive for the OS and a slower drive for media and backups, facilitating easier reinstallation. This setup encourages robust backup practices and helps maintain system integrity. Windows Defender is highlighted as an effective antivirus solution, and preparation for installation, including having necessary drivers on a USB stick, is crucial. A proactive approach to system maintenance can enhance the Windows experience.

Microsoft is asking people to delete their passwords

Microsoft will introduce a new sign-in and account creation process emphasizing passkeys starting in April, impacting over a billion users. New users will verify their email and generate a passkey instead of creating a password, while existing accounts will prioritize passkeys for authentication. Microsoft's goal is to eliminate passwords entirely, as passkeys are tied to a user's device and can be unlocked using biometric methods. The company blocks approximately 7,000 password-related attacks every second, highlighting the vulnerability of traditional passwords. Passkeys are securely stored on devices, reducing the risk of unauthorized access, and are reported to be three times faster than traditional passwords.
