KDE appeals to Windows 10 ‘exiles’

KDE has launched a campaign called "KDE for Windows 10 Exiles" in response to the end of support for Windows 10, which will occur on October 14. The campaign warns users that while Windows 10 will still function after this date, the lack of updates will lead to performance and security declines, increasing risks of hacking. Users face a choice between switching to the Long Term Servicing Channel, paying for extended security updates, or upgrading to Windows 11, which many are reluctant to do due to various reasons, including corporate policies and hardware incompatibility. KDE advocates for transitioning to Linux, specifically its Plasma Desktop environment, emphasizing its user-friendliness and visual appeal. While installing Linux has become easier, KDE advises users to seek help from Linux enthusiasts for a smooth transition. Once installed, KDE claims users will experience fewer data collection issues and no viruses, although users must remain vigilant against Linux malware. It is important to note that while support for many versions of Windows 10 ends on October 14, Microsoft 365 applications on Windows 10 will continue to receive security updates until 2028.

Meta found ‘covertly tracking’ Android users through Instagram and Facebook

Experts at Radboud University and IMDEA Networks found that Meta and Yandex have been covertly tracking Android users by monitoring browser activity without consent. This tracking was first identified in January and involves apps like Facebook, Instagram, and Yandex Maps operating in the background and loading scripts that transmit data back to their respective apps. These scripts bypass Android's security measures, allowing the companies to track users' web browsing activities. The tracking affects all major Android browsers, including incognito mode. Google confirmed that Meta and Yandex exploited Android's capabilities in violation of security and privacy principles. Meta is investigating the issue and has paused the feature, while Yandex claims to adhere to data protection standards. Meta's tracking has been ongoing for about eight months, while Yandex's practices date back to 2017. Facebook tracked users on around 16,000 websites in the EU, and Yandex was active on 1,300 sites. Google has begun implementing changes to address these tracking techniques and is conducting its own investigation. Browsers like Firefox, Microsoft Edge, and DuckDuckGo are also affected, with efforts underway to prevent future incidents.

Meta Pixel halts Android localhost tracking after disclosure

Security researchers have found that Meta and Yandex used native Android applications to access localhost ports, allowing them to link web browsing data with user identities and bypass privacy protections. Following these findings, Meta stopped its data transmission to localhost and removed much of the tracking code to comply with Google Play policies. A report from researchers at IMDEA Networks, Radboud University, and KU Leuven detailed how apps like Facebook and Instagram collected web cookie data via the loopback interface. This method allowed the companies to associate browsing sessions with user identities, undermining privacy measures. Meta's tracking process involved the Meta Pixel script, which transmitted cookies to native apps through various protocols. Meta began using this technique in September 2024 but ceased these practices by June 3rd, 2025. Yandex's localhost tracking dates back to 2017, and while they did not respond to inquiries, browser vendors have implemented mitigations against these practices. Proposed solutions include a new permission for local network access to prevent such tracking in the future.

This Android loophole could have let your apps spy on your web browsing

Meta and Yandex have exploited a loophole in the Android operating system, allowing them to link web browsing data with app identities, bypassing privacy measures like incognito mode. This was revealed by researchers from the Local Mess project, who found that tracking scripts (Meta Pixel and Yandex Metrica) embedded in millions of websites transmit data from web browsers to apps such as Facebook, Instagram, and Yandex Maps through local network connections. Meta began using this technique in late 2024, while Yandex has been doing so since 2017. The loophole allows browser data to be sent to localhost, enabling apps to access it without user notification. In response, Meta has paused the feature and is working with Google to address the issue, which Google acknowledges violates Play Store policies. Some browsers are blocking this tracking, but researchers warn that solutions may be temporary without stricter restrictions on app access to local ports. The study indicates that most sites using these trackers start data collection immediately upon visiting, often before consent is requested. To prevent this tracking, users are advised to uninstall the affected applications.

How to turn off antivirus

Antivirus software is crucial for digital security, providing protection against malware threats. Users may need to disable antivirus temporarily for reasons such as system resource consumption, particularly during resource-intensive tasks like gaming, or to bypass false positives when installing applications. Disabling antivirus software poses risks, especially when browsing the internet, as even legitimate sites can be compromised. Precautions to take when disabling antivirus include disconnecting from the internet, avoiding USB drives, using trusted networks, closing non-essential applications, verifying the legitimacy of downloaded files, and limiting browsing to secure websites. Users should promptly re-enable their antivirus after completing necessary tasks.

This is what data your Windows PC is actually sending back to Microsoft

Windows collects telemetry data, which includes hardware specifications, installed software, and system events, but does not reveal personally identifiable information. This data is encrypted and sent via HTTPS during significant events like system crashes. Users can manage optional data collection settings during initial setup or in the Privacy section of the Settings app, with enterprise versions offering more control. Mandatory data collection in Windows is more extensive than in macOS, while Linux has minimal data collection due to its decentralized structure. Users can disable some data collection, but some information will always be gathered unless advanced measures are taken.

Messaging app Signal will block Windows Recall from taking chat screenshots

Signal has introduced a "Screen Security" feature in its desktop application to prevent external programs, including Windows 11, from capturing screenshots of its interface. This feature is enabled by default and is a response to Microsoft's Recall feature, which captures app window screenshots for AI processing. Signal is concerned about the privacy risks posed by Recall's design, despite Microsoft's assurances of improved privacy controls. The developers have used Windows' Digital Rights Management technology to protect against unauthorized screenshots due to the lack of official APIs from Windows 11. Signal's leadership has criticized the need for such workarounds and has called on Microsoft to provide better tools for developers to safeguard user privacy.

Database performance analysis using pg_profile and pgpro_pwr

pgpro_pwr is a database workload monitoring tool for database administrators (DBAs) to identify resource-demanding operations. It was launched in 2017 as pg_profile by Andrey Zubkov, who moved from being a DBA to an engineer at Postgres Professional. pg_profile is compatible with open-source PostgreSQL and has been integrated into PostgreSQL 17 as of 2024, while pgpro_pwr offers advanced statistical insights and is included in Postgres Pro releases. Both tools monitor database workload metrics through continuously incrementing counters, capturing values at intervals and archiving differences. They do not provide alerting capabilities but are useful for assessing system stability, analyzing load testing outcomes, and identifying system-intensive activities. The tools consist of repository tables, data collection functions, reporting functions, and service tables. To use them, one must install the extension, configure roles, and set up parameters. Reports can be generated for workload statistics over time and comparisons between different time intervals. Examples of report types include wait event statistics and advanced vacuum statistics. Future plans include submitting a patch to introduce vacuum statistics to vanilla PostgreSQL.
