What Happened to the Messenger App Kik?

Kik was founded in 2009 by students from the University of Waterloo and launched in October 2010. The app gained popularity among teenagers, particularly for its anonymous registration process. At its peak, Kik had over 300 million users but became associated with issues like cyberbullying and grooming due to its anonymity. Attempts to implement age verification were largely ineffective. In 2016, Kik explored chatbots for business engagement but faced increasing competition. A blockchain-based cryptocurrency, Kin, was introduced in 2017 but did not revitalize the app. In October 2019, Kik's operations were announced to cease, and it has since existed as a “digital zombie,” with limited visibility and recent fluctuations in its availability on app stores. Kik is currently absent from Google’s Play Store, although the owner, Medialab, is working on a solution.

How Wiz achieved near-zero downtime for Amazon Aurora PostgreSQL major version upgrades at scale using Aurora Blue/Green Deployments

Wiz upgraded its Aurora PostgreSQL database from version 14 to 16, achieving a significant reduction in downtime from approximately one hour to just 30 seconds. The upgrade was facilitated by an automated process called DB Upgrade Pilot, which utilized Amazon Aurora's Blue/Green Deployments. This process involved several steps: taking a cluster snapshot, provisioning a synchronized replica of the production database, executing a VACUUM ANALYZE for performance optimization, monitoring replication lag, and performing a switchover to the new environment. The upgrade included performance enhancements such as improved parallel query execution and faster aggregations, along with enhanced security features. The solution also incorporated safety measures like automatic rollback capability and robust validation steps to ensure a stable upgrade process.

Decentralizing Trust — An Interview with the Team Behind Session Messenger

Session is a decentralized messaging platform that prioritizes user anonymity and metadata resistance. It operates on a network of community-operated servers, eliminating central authority and personal identifiers such as phone numbers or emails for account creation. This design minimizes risks of data breaches and unauthorized tracking. Session does not collect user metadata, which distinguishes it from other messaging apps that may expose user insights through metadata. Users are assigned randomly generated cryptographic keys instead of traditional identifiers, ensuring secure messaging. Messages are routed via a protocol called Onion Requests, which strips metadata during transmission. The platform is open-source, benefiting from community contributions, and aims to enhance user privacy by employing anonymous routing. Recent developments include a migration to the Session Network for improved accessibility and security, and a move to Switzerland for better data protection. Session is introducing a Pro tier to enhance user experience while maintaining free access for all. The platform emphasizes the importance of transparency and robust design in communication tools.

Updating your Linux kernel sounds scary, but here’s why it’s no different from a Windows update

Updating the Linux kernel is generally straightforward and low-risk, similar to Windows updates. Most Linux distributions, including Ubuntu, Fedora, Debian, and Linux Mint, manage kernel updates automatically through the package manager. When a new kernel is installed, the previous version remains intact, allowing users to revert to it if necessary via the GRUB boot menu. Kernel updates provide essential security patches, bug fixes, and improved hardware support. While manual installation of a kernel is possible, it is not required for most users. Tools are available for easier management of kernel versions, but the update process is designed to be user-friendly and safe.

Russia mandates use of new state-controlled messaging app

The Kremlin is launching Max, a state-controlled messaging application for government officials, with a full implementation deadline of September 2025. Developed by VK Company, Max integrates various government services and financial transactions, raising privacy concerns. The Russian government plans to phase out foreign apps like WhatsApp, which currently has a 70% user base. Max will be pre-installed on all new devices sold in Russia starting September 2025. As of July 2025, over 2 million users have registered on the app, which has been labeled a "digital gulag" by cybersecurity experts due to its potential for state-sponsored surveillance. Human rights organizations are concerned about its impact on digital freedoms amid increasing government suppression of dissent.

Google Gemini Android App to Add Audio Uploads for AI Insights

Google's Gemini app for Android is set to enhance its functionality by supporting audio file uploads, as indicated by an APK teardown revealing code strings and user interface elements for this feature. This development will allow users to summarize podcasts, transcribe meetings, and extract insights from voice memos. The introduction of audio capabilities follows earlier features like Audio Overviews, which enable podcast-style discussions from written documents. However, there are significant privacy concerns regarding the handling of sensitive audio data, with fears that Google may access personal information without explicit user consent. Critics warn that audio uploads could lead to unauthorized data scraping and complicate compliance with data protection regulations. Google has mentioned configurable privacy settings to address these risks, but skepticism remains about their adequacy. The anticipated rollout of this feature is expected in the coming months.

Switching to Windows 11: Really more security?

The transition to Windows 11 often requires new hardware, but purchasing a new PC does not guarantee improved security. Users should verify that the latest version of Windows 11 is installed and configure data protection settings, including diagnostic data options. Activating Windows Security, which includes Microsoft Defender Antivirus and a firewall, is advisable, and users should ensure compatibility with third-party antivirus solutions. Creating a system restore point and establishing automatic backups is crucial. Most devices support Secure Boot and TPM 2.0, which should be verified in BIOS or UEFI settings. Users should also remove unnecessary pre-installed software that may pose risks. Ongoing maintenance and updates are essential for maintaining security on a Windows 11 PC.

Microsoft’s Windows Recall is reportedly still capturing passwords and Social Security numbers even after its relaunch

The Microsoft Windows Recall AI app, designed to take screenshots of user activities, has faced security concerns regarding its ability to protect sensitive information. Initially launched in summer 2024 with Copilot+ PCs, it was retracted due to issues capturing sensitive data but returned to Windows Insiders in April 2025. Testing by The Register revealed that while the app's "Filter sensitive information" feature blocked some financial data, it still captured sensitive information like bank balances and failed to recognize variations in phrasing. Users can block specific applications or websites from being captured, but this may limit the app's utility. Recall is intended for laptops with Qualcomm Snapdragon processors, and opting for devices with Intel or AMD chips can help mitigate security risks. Microsoft is reportedly working on improving the app's security features, but its future remains uncertain.

Google Merely Stalls Epic-Ordered Play Store Overhaul With Emergency Stay, Delaying Inevitable Crack In Its Tight Control Over Android Apps And Billing

Google is required to change its app distribution model following a U.S. appeal court ruling that upheld a December 2023 verdict deeming its Play Store an illegal monopoly. The ruling mandates that Google allow third-party billing systems and alternative app stores, with a compliance deadline of fourteen days. Google is seeking an emergency stay to delay the implementation of these changes, arguing that they could disrupt operations and affect revenue, as well as compromise security and user experience. Critics believe Google's actions are aimed at maintaining its market dominance rather than ensuring user safety. An emergency stay has been granted, providing temporary relief but delaying inevitable changes.
