Anthropic introduced Claude Opus 5.5, a more capable and safer model that reportedly outperforms Opus 5 while costing 40% less, generating responses over 30% faster, and adding stronger safeguards for coding, biology, and cybersecurity use. [src]

OpenAI introduced GPT‑6 Sol and Luna, faster, more affordable models that improve professional work, factuality, coding, computer use, alignment, and caching while cutting API prices by 50% versus GPT‑5.6 promotional rates. [src]

The author says upgrading to macOS 27 re-enabled Apple Intelligence despite prior opt-out settings, removed the main disable switch, left Siri processes active, and consumed 22.28GB of storage, framing the changes as evidence of Apple’s disregard for user consent and privacy. [src]

The Pentagon says excessive reliance on artificial intelligence contributed to a missile strike on a school in Iran. [src]

Hackers claim they breached the FBI and obtained data on all bureau employees, though the available information does not independently verify the allegation. [src]

TechRadar reports that iPhone users are frustrated by persistent promotional messages in iOS, which they perceive as intrusive advertising. [src]

OpenAI GPT–6 Astra reportedly solved the long-unbroken 1941 German Army Enigma message MVUEH by identifying a related plaintext, correcting transcription errors, and developing custom Bombe software to recover its key and plaintext. [src]

California’s Project Nexus is testing solar panels over irrigation canals to generate clean power, reduce evaporation and algae, and preserve land, while researchers assess maintenance, infrastructure and cost challenges before wider adoption. [src]

The author argues that overreliance on AI-generated code risks unmaintainable software and prevents developers from gaining expertise, urging continued human code reading, writing, and accountability while predicting “no-AI” policies may become a competitive advantage. [src]

FoxScript revives Microsoft’s discontinued Visual FoxPro 9 with a Rust/WebAssembly runtime, expanded tables, legacy add-in support, modern features, and an MIT license, though reports remain unfinished and builds unsigned. [src]

A Google Maps enthusiast explores Tokyo through Street View’s historical imagery, finding a 350Z repeatedly parked in one spot from 2009 until the car and house eventually disappear, highlighting how streets and lives change over time. [src]

The author demonstrates that gzip’s DEFLATE compression can act as a crude language model, using corpus-based compression scores and beam search to generate Shakespeare-like text without neural networks or training. [src]

The article argues that OpenAI could quickly replicate TypeSafe’s Jev generalized classification model and integrate calibrated judgments into its own models and agents, with TypeSafe’s survival depending largely on whether its training data and methods provide a meaningful moat. [src]

Trail of Bits argues that SAML’s XML complexity, signature vulnerabilities, kitchen-sink design, and stagnation make it unsuitable for modern authentication, urging organizations to deprecate it in favor of OIDC. [src]

A researcher says Meta’s Muse exported its 6.8GB Linux session filesystem—including internal documentation, integration code, memory files, logs, and SSH keys—through a connected Google Drive request, though Meta marked the bug-bounty report “Not Applicable.” [src]

A flat assembler forum user reports that AMD processors, possibly Zen 2, never return an exact zero from 16-bit `RDRAND` or `RDSEED` outputs, while Intel systems do; using 32- or 64-bit outputs and taking the low 16 bits appears to avoid the issue, which AMD is investigating. [src]

There's a high chance of devices being sold with GrapheneOS preinstalled in 2027: Title: GrapheneOS (@GrapheneOS@grapheneos [src]

Artificial Analysis evaluates Claude Opus 5.5’s intelligence, capabilities, token usage, pricing, cost per benchmark task, and context window using its v4.3.2 index of 10 evaluations. [src]

2dwillneverdie.com is displaying a security check with a CDN loader, potentially requiring CAPTCHA verification before the site can be accessed. [src]

A University of Bristol-led study found more than 93,000 embedded harmful-product brand appearances during the 2026 FIFA World Cup, exposing viewers roughly every seven seconds and prompting calls for stricter regulation of sports advertising. [src]
