HTTP/3's Current State: Challenges and Opportunities on the Path to Adoption

The HTTP/3 specifications are complete but await final publication. Server-side support is surprisingly high, particularly among top websites. Major players like Cloudflare have enabled HTTP/3, and browsers widely support it. However, client-side support, such as in curl, remains incomplete, largely due to the lagging development of QUIC-enabled TLS libraries. OpenSSL's QUIC support has been delayed, while alternatives like BoringSSL and quictls have limitations. While HTTP/3 promises speed improvements, real-world benefits depend on network conditions. Widespread adoption hinges on specification release and mature TLS libraries.

Clang Optimization Regression: Inlining Backfires in C++ Benchmark

2025-02-19

A C++ benchmark revealed a performance regression in Clang's optimization of inline functions. When the `increment` function was inlined, branch prediction failures resulted in roughly a 5x slowdown compared to the non-inlined version. `perf stat` confirmed branch mispredictions as the culprit. Interestingly, compiling with the Zig toolchain significantly improved performance, suggesting a potential regression in Clang 19. The issue has been reported on the Clang/LLVM repository, with initial investigation pointing to a trade-off between SROA and SimplifyCFG optimization passes.

Is Current AI a Dead End?

Professor Eerke Boiten of De Montfort University Leicester argues that current AI systems based on large neural networks, such as ChatGPT, are unsuitable for critical applications due to their inherent complexity and unpredictability. These systems lack manageability, transparency, and accountability; their behavior is emergent rather than compositional, making effective verification and error correction difficult. Boiten suggests that the current direction of AI development may be a dead end, advocating for compositional neural networks or hybrid approaches combining symbolic reasoning to build more reliable AI systems.

Heat Accelerates Auto Chip Aging, Raising Safety Concerns

New research shows that automotive chips are aging significantly faster than expected in hot climates, shortening the lifespan of electric vehicles and potentially creating new safety issues. In areas like Phoenix, Arizona, where high temperatures can persist for weeks, cabin temperatures can reach 93°C, severely impacting chip longevity. Studies reveal that for a chip designed for a 30-year lifespan, high temperatures reduce life expectancy by an additional 10% annually. Chipmakers are working to address this, requiring new materials, design redundancy, and active cooling solutions. Increased chip utilization due to autonomous driving exacerbates the problem. Proactive monitoring and predictive failure analysis will become crucial, impacting both vehicle reliability and safety.

Bacteria Build Living Gels in Polymers: A New Twist on Biofilms

Caltech and Princeton University scientists have discovered that bacteria growing in polymer solutions, like mucus, form long, intertwined cables—a kind of ‘living Jell-O.’ This is significant for understanding diseases like cystic fibrosis, where thickened lung mucus fosters dangerous bacterial infections. The discovery also has implications for studying biofilms (the slimy coatings on surfaces) and their industrial impacts. The researchers found that external pressure from the polymers forces the bacterial cells together. A theoretical model accurately predicts when these cable structures will form. The reason for cable formation remains a mystery: it may be a bacterial defense mechanism or conversely, a way for the body to expel the infection more easily. This unexpected finding opens up new avenues of research into bacterial growth and biofilm control.
