LLM (Large Language Model) inference often suffers from memory constraints, with GPUs spending significant time waiting for data rather than performing computations. To address this, batching allows for processing multiple requests simultaneously, but each request requires its own Key-Value (KV) cache, leading to substantial memory waste due to fragmentation and over-allocation, typically ranging from 60% to 80%. vLLM's PagedAttention technology dramatically reduces this waste to under 4%, resulting in up to 24

AI is significantly advancing the field of formal verification, with AI-assisted mechanical proving companies now garnering billion-dollar valuations and new users engaging with proof assistants, particularly Lean. These tools are showing impressive results in prestigious competitions and addressing challenging open mathematical problems. Notable researchers like Terry Tao and Martin Kleppmann express excitement about the potential of AI in this domain. However, there are major challenges in formal verification. A primary hurdle is the lack of formal specifications for most software, which complicates the verification process

The article discusses the relevance of Nagle's algorithm, introduced in RFC 896 in 1984, in the context of modern distributed systems. The author highlights that enabling the TCP_NODELAY socket option can often resolve latency issues caused by small packet transmissions, which Nagle aimed to optimize. Nagle's algorithm was designed to reduce the overhead associated with sending numerous small packets by preventing the transmission of new TCP segments until previously sent data is acknowledged, thereby improving throughput. However, it can interact poorly with

HistoSonics has developed the Edison system, which utilizes a water-filled membrane to deliver focused ultrasound for treating pancreatic cancer. This system exploits cavitation—the formation and collapse of tiny gas bubbles—causing mechanical stress that destroys cancer cells and liquefies tumors. Initially viewed as a harmful side effect, cavitation was studied by researchers at the University of Michigan starting in 2001, leading to breakthroughs in harnessing it for medical purposes.

In high-scale distributed systems, even a slight increase in latency in a leaf service can lead to cascading failures, where localized performance degradation escalates into complete site outages. A core issue in microservices architectures is the use of synchronous, blocking I/O within fixed thread pools. When a downstream service experiences significant latency, it blocks the worker threads in the calling service, leading to resource exhaustion. For instance, an API gateway with 200 worker threads can quickly become saturated if it waits on a slow downstream service
