Garnet Chan and collaborators show that the ground-state energy of FeMo-co, the nitrogenase active site, can be accurately computed with classical methods. By pruning electronic configurations with two complementary techniques, they obtain a ground-state energy that matches experiments, challenging the view that nitrogenase requires a quantum computer. While quantum devices may help model dynamics, the result suggests many key chemical problems can be tackled classically today. The work shifts the quantum-advantage debate toward scalability and broader applicability, with the goal of eventually modeling the full enzyme.

Anthropic is expanding Project Glasswing to about 150 new organizations across 15+ countries, bringing Claude Mythos to critical infrastructure (power, water, healthcare, communications, hardware) to detect zero-day vulnerabilities. The move follows a confidential IPO filing after a $65B funding round at near-$1T valuation. New partners include Okta, Samsung, SK Hynix, SK Telecom, NATO, and ENISA, with participants in Australia, Canada, France, Germany, Italy, Switzerland, the Netherlands, Spain, Belgium, Sweden, India, Japan, New Zealand, and South Korea. OpenAI recently released a similar model, GPT-5.5-Cyber.

Perplexity introduces Search as Code (SaC), a programmable search architecture that makes search controllable by AI agents. Traditional monolithic pipelines are rigid; SaC exposes low-level search primitives via an Agentic Search SDK and lets models generate Python code executed in secure sandboxes to assemble task-specific pipelines with thousands of retrievals. SaC has three layers: models (control plane), sandboxes (execution), and the SDK (building blocks). It uses filesystem-based serde to share state across turns. Case studies and benchmarks show SaC outperforms alternatives and offers strong cost-performance gains, with autoresearch refining the SDK. Available today in Perplexity Computer.

Jason Zweig shares his father's rule for making a living: 1) Lie to those who want to be lied to, and you’ll get rich; 2) Tell the truth to those who want the truth, and you’ll make a living; 3) Tell the truth to those who want to be lied to, and you’ll go broke. The piece notes the quote’s origin in The Wall Street Journal.

TechRadar Pro highlights Larry Ellison’s warning that AI-driven surveillance could force citizens to behave, as constant recording and reporting expand. He envisions cameras feeding real-time video into AI to detect and automatically report issues, fueling pervasive monitoring. The piece frames this as a modern dystopia akin to Orwell’s 1984 and notes rising surveillance in workplaces and by authorities, underscoring concerns about AI-enabled policing and society-wide tracking.

An executive order to accelerate AI innovation and security by partnering with industry and modernizing government while strengthening cyber defenses. It mandates rapid cyber hardening of national security and civilian federal systems, creates an AI cybersecurity clearinghouse, and develops a voluntary framework and benchmarking process to designate and share access to 'covered frontier models.' It rejects mandatory licensing, strengthens enforcement against AI-enabled cybercrime, and expands the federal cybersecurity workforce in coordination with key agencies.

Braun argues that interoperability is an ongoing process, not a one-off spec. He recounts co-editing the Subresource Integrity (SRI) spec, which uses SHA2 digests to secure third-party JS; a base64 vs base64url encoding issue in 2025 exposed cross-browser differences and led to a standard tweak—yet true compatibility requires continuous maintenance. The piece stresses iterative co-design, shared test suites, and vigilance because even simple formats (JSON, HTML, XML) reveal parser differences that can cause security flaws. Interop is asymptotic and security depends on sustained scrutiny.

Coreutils for Windows is a Microsoft-maintained port of uutils/coreutils, findutils, and GNU-compatible grep packaged as a single multi-call binary to provide Linux/macOS/WSL-like commands on Windows. The project aims for frictionless scripting across environments, with each command supporting --help. It’s in preview. Install via winget: winget install Microsoft.Coreutils, or from the release page. PowerShell 7.4+ required; some commands conflict with built-ins. Caveats include CRLF line endings, no /dev/null (use NUL), limited POSIX signals, and Windows ACL-based permissions. Some POSIX-only commands are omitted. Contributing encouraged.

The piece argues that America’s anti-data center backlash stems from broader AI anxiety and a stalled national AI policy. Communities oppose centers over noise, energy, water use, and land impact, but treating data centers as the core issue misreads AI’s threats. Environmental objections are overstated; local bans won’t slow AI or govern its use. Instead, the author calls for a national, deliberative AI policy that expands human agency—via shorter workweeks, universal paid leave, worker control, or public ownership—rather than relying on local zoning fights.

Plasma is fully transitioning from X11 to Wayland. Plasma 6.8 will remove the X11 login session and purge X11-specific code in Plasma Shell, System Settings, and device configuration; XWayland remains for X11 apps. Plasma 6.7 is the last release to include an X11 session. KDE data show over 95% of 6.6 users on Wayland and about 76% overall Wayland adoption; no retroactive changes for older releases. Some workflows may need adjustment, but feedback is welcome to improve the transition.

Stephen Cass's May 2026 Hands On piece "Reviving Teletext for Ham Radio" describes recreating teletext as a ham-radio data mode. Using AX.25, he transmits 40x24 teletext pages; at 1,200 baud on VHF/UHF (about 11 seconds per page) or 300 baud on HF (≈44 seconds). Pages are repeated to fill gaps. He built Spectel in Python, aided by vibe coding and Anthropic’s Claude, and uses a Bedstead font to emulate teletext and references the SAA5050 chip. He invites ham partners to try HF experiments.

Meta repeatedly ignores an EU-backed appeals body over user bans on Facebook, Instagram and Threads. Appeals Centre Europe reviewed 4,600 ban cases but Meta supplied relevant content in fewer than 100. The BBC and others have documented numerous cases where users were blocked with no recourse. ACE found that in most hate-speech rulings platforms failed to enforce policies, and in about 3,000 reviewed cases the body disagreed with platforms 59% of the time. Meta did not comment.

Argues that .NET Custom Attributes are a nightmare: arguments are stored as large fully qualified name strings in the metadata blob instead of compact tokens. Enum values, Type references, and nested types force expensive type resolution (assembly probing, type forwards) and complex FQN parsing. This bloats blobs, slows parsing, and makes resolution inconsistent across corelibs and references. The author suggests using metadata tokens or primitive element types would be far more efficient and notes backward compatibility preserves the current, inefficient design.
