Migrating mission-critical payments at Nubank to Amazon Aurora PostgreSQL

Nubank, a digital banking platform with approximately 135 million customers in Brazil, Mexico, and Colombia, faced challenges with its payment infrastructure due to inefficiencies in managing 7.5 TB of self-hosted PostgreSQL databases. Queries took over 13 minutes to execute, and replication lags exceeded four minutes during peak times. To address these issues, Nubank evaluated database solutions based on developer productivity, operational efficiency, performance reliability, and scalability. They selected Amazon Aurora PostgreSQL-Compatible Edition for its compatibility, performance improvements, and automated features. The migration to Aurora was facilitated by AWS Database Migration Service (AWS DMS), which minimized downtime and allowed for efficient transition. Post-migration, query performance improved significantly, with some queries executing up to 1,900 times faster, and overall end-to-end service latency decreased, enhancing customer experience. The migration resulted in a 25 percent cost reduction and ensured compliance with regulatory requirements.

Russia’s Max Messenger Removed From Google Play

Max, a messaging application launched by VK in 2025 and endorsed by Russian President Vladimir Putin, was removed from Google’s Play marketplace on July 16, 2023. The app does not provide end-to-end encryption, raising concerns about government access to user communications. This removal is part of a trend affecting other VK-owned applications, coinciding with recent EU sanctions targeting VK Company and its subsidiary Communication Platform LLC, which oversees the Max app. The EU characterized Max as having extensive surveillance features used against critics of Russia's military actions in Ukraine. Apple also removed Max from its App Store in June without explanation. Max aims to be an all-encompassing platform for messaging, social media, digital identification, payments, banking, and government services, which critics say could enhance government monitoring of citizens. The Russian government has implemented strict measures against foreign social media platforms and previously enacted a ban on Telegram in 2026, which faced public backlash.

Can Chromebooks Get Viruses? How to Protect Your Device

Chromebooks are designed with robust security features, including sandboxing, Verified Boot, automatic updates, data encryption, and Recovery Mode, which collectively reduce the risk of malware infections. However, they are still vulnerable to threats such as malicious Chrome extensions, scam Android apps from third-party stores, phishing attacks, and risks associated with using Developer Mode and cloud storage. Users can identify potential malware through signs like slow performance, unexpected pop-ups, and unusual battery drain. To remove malware, users should eliminate suspicious extensions, uninstall dubious apps, run antivirus scans, enable Google Play Protect, or perform a Powerwash to reset the device. To protect their Chromebooks, users should avoid Developer Mode, check app permissions, use two-factor authentication, verify website URLs, and use a VPN on public Wi-Fi.

Former Destiny 2 and Marathon director settles $200 million lawsuit against Sony and Bungie: ‘The outcome is one I am very satisfied with’

Christopher Barrett, former director at Bungie, has settled his lawsuit against Sony and Bungie after alleging a "premeditated scheme" to terminate his employment. He sought [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Former director Christopher Barrett, known for his pivotal roles in the development of Destiny 2 and Marathon, has reached a settlement in his lawsuit against Sony and Bungie. While the specific terms of the settlement remain undisclosed, Barrett expressed his satisfaction with the outcome, suggesting a resolution that aligns with his interests. Background of the Lawsuit Barrett's tenure at Bungie spanned nearly 25 years, during which he played a crucial role in shaping the Halo and Destiny franchises. His unexpected departure in 2024 was followed by allegations of inappropriate behavior, leading him to file a lawsuit seeking 0 million. In his claims, Barrett accused Sony and Bungie of orchestrating a "premeditated scheme" to terminate his employment, thereby evading the substantial financial obligations owed to him and positioning him as a scapegoat for the companies' broader challenges. Initially, Sony appeared poised to contest the lawsuit vigorously. The company's response included various communications between Barrett and female colleagues, which they argued illustrated a troubling pattern of misconduct. These communications allegedly featured inappropriate comments and requests, including drunken calls and sexually charged games. However, Barrett's legal team countered that Sony had misrepresented these interactions by selectively presenting text messages and conversations. Financial Implications In its defense, Sony provided a detailed account of Barrett's earnings following its acquisition of Bungie in January 2022. He received over million in 2022 and approximately .9 million in 2023, with an additional million slated for the years 2024 to 2026. This amount included payments for unvested restricted stock units and re-vested shares, underscoring the financial stakes involved in his termination. The acquisition itself was marked by a significant investment in talent retention, with Sony allocating .2 billion to ensure key personnel, including Barrett, remained with Bungie. However, as layoffs swept through the studio in subsequent years, the wisdom of these retention strategies came into question. The financial incentives designed to keep top talent on board began to seem less prudent amid the backdrop of workforce reductions. A Positive Resolution Despite the tumultuous circumstances surrounding his departure and the lawsuit, Barrett's settlement appears to have yielded a favorable outcome for him. While the exact figures remain undisclosed, it is reasonable to surmise that he may have secured a significant portion of the compensation he sought. This development comes shortly after Bungie announced layoffs affecting many members of the Destiny development team, highlighting the ongoing challenges within the studio. In a collaborative statement shared by Barrett on LinkedIn, both Sony and Bungie acknowledged his contributions to the success of their games, affirming that his name will be included in the credits for Marathon as the original game director. This recognition serves as a testament to Barrett's lasting impact on the gaming landscape, even amidst the complexities of his recent experiences." max_tokens="3500" temperature="0.3" top_p="1.0" best_of="1" presence_penalty="0.1" frequency_penalty="frequency_penalty"] million in damages following accusations of inappropriate behavior that led to his departure in 2024.

Why Antivirus Alone No Longer Protects Small Businesses

Many small businesses have historically relied on antivirus software for computer security, which was effective against identifiable malware. However, the current cyber threat landscape includes sophisticated attacks such as phishing, credential theft, and ransomware that traditional antivirus solutions may not adequately address. Factors driving increased cyber threats in Kenya include phishing, weak authentication practices, delayed software updates, and the use of artificial intelligence by malicious actors. While antivirus software can detect known malware and block common threats, it falls short against tactics like stolen credentials and social engineering. The Communications Authority recommends complementing antivirus with multi-factor authentication, regular software updates, secure configurations, and user training. Endpoint Detection and Response (EDR) solutions enhance visibility into attacks by monitoring endpoint activity for suspicious behaviors, allowing for prompt investigation and response. A layered security strategy that integrates multiple protective measures is essential for effective cybersecurity, and many modern security platforms offer unified solutions to simplify management for smaller organizations. The Kaspersky SMB Cybersecurity Guide provides insights into modern attack methods and the role of endpoint protection in improving a business's cybersecurity posture.
