The current estimate of the world’s population is 8.264 billion people, so the share price of SpaceX is currently at a phenomenal USD $261 per head. The analysis from space monitoring firm LeoLabs, provided to Breaking Defense, found that from January 2021 to January 2025 China has abandoned 51 spent rocket bodies in LEO above 650 kilometers (about 404 miles) in altitude, more than doubling the number for the previous five years to bring the total to 96. A big problem, Pauzauskie said, revolves around reproducibility. So far, labs haven’t been able to show that they can consistently cool semiconductors. This article recounts the evolution of modern computing systems to provide an analysis of security risks and their evolution, with a past and present look at key cyber-defense innovations as well as a perspective on future cybersecurity hard problems. Worth Reading 062926 It’s no longer just about your IP address or the specific endpoint you think you’re connecting to, it’s about your location and which intermediary services can most effectively handle your request. Earlier this month, a German court ruled that Google is liable for its AI search summaries. Rejecting defenses like “users can check for themselves,” and that they generally know “that information generated with AI should not be blindly trusted,” the court held that the AI’s summaries are reflections of the company and “above all an expression of Google’s business activities.” The distribution of Content Delivery Networks (CDN), cloud and content provider capacity across Internet Exchange Points (IXPs) provides a fascinating lens into the physical infrastructure of the Internet and public peering. The memory market – by which we mean dynamic main memory as well as flash persistent memory – has been utterly and perhaps forever changed by the GenAI boom. These days you could be excused by suspecting that the world has gone AI-mad, and if you were at the NANOG meeting your suspicions would’ve only been confirmed! Worth Reading 062426 As the development of data centers in the U.S. faces intense criticism from local communities and legal action, project supporters are claiming “foreign influence” could be fueling the fire. In this bingecast installment of the Mind Matters News podcast, host Robert J. Marks welcomes economics professor and author Gary Smith to discuss the hype around artificial intelligence and its impact on the market. In the DNS name resolution space queries are free. To what extent do we see over-querying on the part of recursive resolvers in the DNS? Over the past year, the Ethernet community has examined 400Gbps‑per‑lane signaling from many angles: AI network use cases, modulation options, channel limitations, and technology feasibility. Those discussions have been necessary, but they now need to converge into decisions that allow the industry to move forward. For most of the internet era, distribution was scarce and content was abundant. Platforms that controlled distribution captured the majority of value. older posts
