A better, more nuanced understanding of tasks in recommender systems can help minimize user costs across the entire recommendation process.

 


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.

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!

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.

In this post, I discuss our recent work that models and analyses the resilience of authoritative DNS infrastructure that supports individual domain names on the Internet.

 


The RIPE NCC made its all-powerful single sign-on tokens available to over 1000 third parties. From a single link click, any logged-in RIPE NCC user would leak their session token.

 


Identifying active IPv6 addresses is a challenging task, but it’s also an important one. As researchers and network operators, it helps us understand the current deployment, identify weak spots that need strengthening, and detect vulnerable devices for disclosure.

 


The fundamental bubble barometer is that speculators buy an asset because they expect the price to keep rising, not because they want the income generated by the asset. Indeed, most speculators don’t plan on holding the asset long enough receive any income.

 


Recently, there has been a surge in progress in quantum computing that has shortened the hypothetical timeline on which quantum computers can ‘break’ traditional public-key cryptography that uses the RSA scheme.

When business volume and market capitalization cross a critical threshold, vertically integrating infrastructure ceases to be merely a cost-cutting financial tactic; it becomes an existential imperative for computational resilience and commercial survival.

 


It looks like industry mergers and acquisition activity is in high gear lately.

 


Building multi-agent systems right now feels painfully identical to the early, chaotic days of the micro services gold rush.

 


The standard is called DNS-AID (Domain Name System for AI Discovery). Its premise is that the internet already solved the problem of finding things at scale forty years ago with DNS — and that the same infrastructure should handle AI agents.

 


Mythos is real. I know a big chunk of the industry thinks it’s a marketing stunt, and I get why. I get it. But I’ve seen the findings, and they’re bad.

In a paper published late in 2025, Østergaard and colleagues reported on their examination of almost 40 psychiatric referrals across Denmark that implicated AI chatbots in harmful interactions, including suicidal thoughts, eating disorders, and fostering delusions

 


Since its deployment in 2011, the adoption of RPKI by Internet Service Providers has shown continuous growth, a trend that persists to this day. As this growth continues it is important to measure its effect on BGP stability.

 


AI companies, AI influencers and famous professors have been making extraordinary claims for years about AI.

 


A robotic system that can produce a rubbery pancake is a true technical and logistic achievement, but why all this work to automate the production of mediocrity?

 


The greatest risk we face today isn’t that AI is becoming “too smart”; it’s that we are beginning to treat this technology as an infallible “oracle” rather than a capable, yet fundamentally fallible, “intern.”

A BBC journalist recently performed a silly experiment to prove a very serious point. In just 20 minutes, he manipulated ChatGPT and Google into telling the public he was a world-champion competitive hot dog eater.

 


Many (perhaps most) of the BGP route leaks reported on Cloudflare Radar (as with its predecessors) are what I term ‘ephemeral leaks‘, brief routing anomalies that exist only momentarily during convergence and have little to no operational impact.

 


In this episode of PING, APNIC Chief Scientist Geoff Huston and I discuss the Network Time Protocol (NTP). NTP is one of the oldest systems we rely on today.

 


The Gentlemen ransomware is a ransomware-as-a-service (RaaS) threat that is distinguished by its ability to pair its strong per-file encryption with an aggressive self-propagation capability designed to enable broad network compromise.

 


LLMs can help tame the complexity at the root of many of today’s software security challenges.
