H5N1 avian flu virus has been detected in wastewater samples from 10 Texas cities, coinciding with outbreaks in cattle herds. Researchers found the virus in 100 of 399 samples between March 4 and July 15, 2024. Despite widespread detection, no correlation was found with flu-related hospitalizations, suggesting low risk to human health. The first US human case was confirmed in March, but all infected individuals have since recovered. The detection points to multiple animal sources, though direct contact with infected cattle is deemed necessary for risk.

The Department of Justice has filed a complaint against RealPage, a software firm, for allegedly facilitating a price-fixing conspiracy among corporate landlords that has contributed to a significant spike in rental inflation. It is estimated that up to 25% of rental inflation from 2020-2024 could be linked to this scheme, affecting millions of renters nationwide. Despite the potential macroeconomic implications, the Federal Reserve and economists have largely overlooked this issue, raising concerns about its impact on housing affordability and overall economic policies.

GitHub notification emails were compromised to distribute malware. Attackers use fake GitHub accounts to create and quickly delete issues on public repositories, tricking developers into clicking on spoofed notifications. The emails impersonate GitHub Security and contain malicious links redirecting to malware download sites. Once downloaded, the malware, identified as "LUMMASTEALER," searches for sensitive data like cryptocurrency wallets. The article highlights the need for GitHub to enhance email security by minimizing attacker-controlled content and improving context clarity. The malware's signature is likely spoofed, misleading users about its legitimacy.

Real-time Linux has officially been integrated into the Linux kernel with the upcoming 6.12 release, after years of development and debate. This integration means users can run real-time applications without needing special patches. While it may not significantly impact desktop performance, it enhances system reliability for critical applications like automotive controls and industrial machinery. The inclusion of PREEMPT_RT simplifies maintenance and reduces reliance on out-of-tree patches, potentially affecting real-time OS solutions providers.

Digital signatures verify the authenticity of digital messages, ensuring they haven't been tampered with and confirming the sender's identity. While widely used, there's a disconnect between their conceptual framework and practical applications. Cryptographic techniques like Schnorr signatures, derived from interactive identification protocols, are more suitable for specific uses. The author argues that many signature applications, especially for identification, lack proper context and can be insecure. Alternatives like HMAC are recommended for most scenarios, as signatures often impose unnecessary risks, including non-repudiation and vulnerability to key compromise from nonce reuse.

The article discusses GPU debug scopes for rendering APIs that capture GPU workloads. It emphasizes that diagnostic tools like RenderDoc and Nsight-Graphics, while useful, often provide a flat list of API calls that are difficult to analyze. By attaching diagnostic data using RAII (Resource Acquisition Is Initialization) patterns, developers can better manage and visualize their command-buffer operations. The article details implementations of RAII in C++, C#, and Rust, and illustrates how Vulkan and OpenGL facilitate labeling and debugging command buffers, enhancing error diagnosis and profiling capabilities.

The article discusses modeling a message-passing bug using TLA+. The bug originated from incorrect assumptions about message order in a multi-threaded environment with three queues. The proposed fix involved sending messages from the same thread and simplifies the system by reducing the queues to two. The author emphasizes the utility of TLA+ for clarifying concurrent aspects of systems, highlighting that coding often obscures subtle concurrency issues due to surrounding business logic. The article concludes that employing mathematical modeling aids in understanding these complexities better.

Leonard Cohen’s career and artistry diverge from typical rock stardom, embodying a deep authenticity that resonates across generations. Initially reluctant, Cohen embraced performance later in life after financial difficulties led him back into music. His profound songs like “Hallelujah” reflect a unique blend of vulnerability and intellect. Scholar Christophe Lebold’s book portrays Cohen as a figure resisting male egoism, celebrating human fallibility instead. Cohen's late-career revival culminated in acclaim, culminating in a farewell album that embodied themes of spiritual reconciliation and mortality. He passed away in 2016, shortly before the election of Donald Trump, marking a symbolic end to his lifelong artistic battle against egoism.
