Google's AI Summaries: A Publisher's Nightmare?

Google's new AI-generated summaries in search results often pull content, diverting traffic away from websites. Publishers face a dilemma: blocking summaries reduces visibility, while allowing them means surrendering content control. While EU and UK investigations are underway, effective workarounds remain scarce. The article outlines several options, including the `max-snippet:0` and `nosnippet` meta tags, and the `data-nosnippet` attribute, but none are perfect. Ultimately, it labels this a classic 'dark pattern' design, heavily disadvantaging publishers, and calls for regulatory intervention.

It's Time to Delete Some Tests

2025-08-30

For decades, the importance of testing has been emphasized, yet developers have developed a misguided belief that 'deleting tests is blasphemy'. This article argues that the purpose of tests is to increase confidence, but failing, redundant, slow, or outdated tests actually decrease confidence. Flaky tests waste time, while overly numerous tests reduce efficiency. The author suggests that to improve efficiency and confidence, tests that decrease rather than increase confidence should be deleted, and new tests should be written for new requirements.

15x Power Boost for Solar Thermoelectric Generators via Synergistic Spectral and Thermal Management

Researchers significantly improved the power output of solar thermoelectric generators (STEGs) by optimizing both hot- and cold-side thermal management. They employed a selective solar absorber (SSA) to maximize solar energy absorption and minimize radiative losses, while using an air film to reduce convective losses on the hot side. On the cold side, a micro-dissipator (μ-dissipator) was designed for efficient heat dissipation through convection and radiation. Experiments demonstrated a 15x peak power enhancement when combining both hot- and cold-side optimizations, enough to power an LED, showcasing the potential for applications in IoT and beyond.

From Multi-Head to Latent Attention: A Deep Dive into Attention Mechanisms

This article explores the evolution of attention mechanisms in natural language processing, from the initial Multi-Head Attention (MHA) to more advanced variants like Multi-Latent Head Attention (MHLA). MHA weighs important words in context by calculating query, key, and value vectors; however, its computational and memory complexity grows quadratically with sequence length. To address this, newer approaches like MHLA emerged, improving computational speed and scalability without sacrificing performance – for example, by using KV caching to reduce redundant calculations. The article clearly explains the core concepts, advantages, and limitations of these mechanisms and their applications in models like BERT, RoBERTa, and Deepseek.

Cloudflare's Signed Agents: A Path to a Closed Web?

Cloudflare's new "signed agents" system, pitched as a safety measure, is argued to be a dangerous path towards a closed web. The system functions like an allowlist, deciding which agents can access the web, contradicting the open nature of the internet. The author advocates for open, portable, and company-independent authentication based on verifiable chains of delegation and request-level proof, rather than a single company's control. The article draws parallels to historical events, highlighting how open standards consistently beat closed plugins, and calls for an open, verifiable, and decentralized authentication system to manage the increasing number of web agents, ensuring the openness and innovation of the internet. The author even offers to open-source a first cut of their proposed solution.

Steam UK Implements Credit Card Age Verification, Bypassing VPN Workarounds?

To comply with the UK's Online Safety Act, Steam now requires all UK users to verify their age with a credit card to access mature content and games. This has sparked controversy, as users without credit cards are locked out. Valve claims this maximizes user privacy and prevents age verification circumvention. Weeks after the UK's new age-gating rules were found easily bypassed via VPNs, and following brief exploits of Discord and Reddit's age verification, this move is significant. Microsoft is also rolling out Xbox age verification in the UK, currently optional but mandatory in early 2026.

SGLang: An Open-Source Implementation Matching DeepSeek LLM's Inference Performance

DeepSeek, a popular open-source large language model (LLM), boasts impressive performance. However, its massive size and unique architecture (using Multi-head Latent Attention and Mixture of Experts) demand a sophisticated system for efficient large-scale serving. This blog details how we achieved near-parity with DeepSeek's inference system performance using SGLang. Our implementation, running on 12 nodes (each with 8 H100 GPUs) in the Atlas Cloud, leverages prefill-decode disaggregation and large-scale expert parallelism (EP), reaching 52.3k input tokens/second and 22.3k output tokens/second per node for 2000-token input sequences. This is, to our knowledge, the first open-source implementation to nearly match DeepSeek's reported throughput at scale, at roughly one-fifth the cost of the official DeepSeek Chat API.

Intel Xeon 7: Can 18A and 3D Packaging Turn the Tide?

With AMD holding over 40% revenue and 27% shipment share of the x86 server CPU market in the first half of 2025, Intel is betting on its Xeon 7 processors (Clearwater Rapids and Clearwater Forest), launching in 2026, to regain ground. These CPUs leverage the 18A process, 2.5D EMIB interconnect, and Foveros 3D stacking—technologies first deployed (with delays) in the datacenter with the ill-fated Ponte Vecchio. The success of Xeon 7 hinges on stemming AMD's momentum and countering the rise of hyperscaler's custom Arm server CPUs. While the energy-efficient E-core variants have a niche market, they aid Intel in refining its 18A process and 3D packaging. This article details the architecture of the Clearwater Forest E-core processor, including its improved RibbonFET transistors, PowerVia backside power delivery, and 3D packaging, and analyzes its performance potential.

Efficient Rubik's Cube Solving via Learned Representations: No Hand-Crafted Heuristics Needed

2025-08-29

Classical AI separates perception (spatial representation learning) from planning (temporal reasoning via search). This work explores representations capturing both spatial and temporal structure. Standard temporal contrastive learning often fails due to spurious features. The authors introduce Contrastive Representations for Temporal Reasoning (CRTR), using negative sampling to remove these features and improve temporal reasoning. CRTR excels on complex temporal tasks like Sokoban and Rubik's Cube, solving the latter faster than BestFS (albeit with longer solutions). Remarkably, this is the first demonstration of efficiently solving arbitrary Rubik's Cube states using only learned representations, eliminating the need for hand-crafted search heuristics.
