IMF warns a sharp AI stock correction could destabilize markets worldwide. Sky-high AI valuations and rising corporate debt, plus leverage and circular financing, raise the risk of a global spillover and tighter financial conditions. The US leads exposure, with Asian markets most vulnerable; the UK/euro area somewhat insulated. The report cites three near-term catalysts: AI-driven market weakness, rising government borrowing costs, and cyber-attacks. Hyperscalers and the “Magnificent Seven” dominate valuations, but AI gains may be smaller than anticipated.

Jim Nielsen’s blog post traces the Mac Dock’s history from OS 10 to macOS 27, recounting how he researched macOS icon design after writing for The iOS App Icon Book. He compiled the evolution of macOS docks into a single graphic (with 512 Pixels’ compilation) and offers a high‑resolution version to preserve/archive it; the post invites replies via Email, Mastodon, or Bluesky.

Ben Recht critiques OpenAI’s blog claiming a faster FFT, arguing the claimed improvement rests on an unrealistic model of computation and misuses big-O. He sketches the FFT's Cooley–Tukey algorithm (n log n, ~5 n log n ops) and notes OpenAI's result would require arbitrary-precision complex arithmetic and astronomical constants, making it impractical. Recht argues the purported speedup is asymptotic and irrelevant to real hardware, citing Morgenstern and Ailon's limits, and accuses modern theory of detaching from computers. He laments theory papers that claim breakthroughs without implementing algorithms, urging focus on practical computation.

Anthropic says it has strengthened Claude defenses against distillation attacks, dramatically reducing distillers' data harvest (about 90–99%). Distillation lets attackers copy frontier model capabilities for cheaper, with cyber and national-security risks. New measures: preserved thinking (restricts access to unsummarized reasoning for new accounts), a two-stage classifier with red-teaming to block extraction and a <0.1% false positive rate, and stricter usage limits plus charges for blocked requests. Result: reasoning tokens distilled on their platform drop 10–100x; tens of thousands of accounts banned. Still a cat-and-mouse effort with trade-offs for legitimate users; industry-wide cooperation needed.

Ryan Bigg says he’s leaving tech after applying to over 36 jobs and getting 24 rejections, citing a damaged market and mental strain. With 20 years as a developer (Ruby/JS), author, speaker, and maintainer of popular Ruby packages, he notes real value to shareholders and team growth from 2 to 12. He argues AI hype misleads and, while using AI for coding, he reviews it before production. Based in Warrnambool, remote work works for him; hybrid is infeasible. He plans to figure out what’s next.

Auto Research by Supers provides a rigorous, reproducible protocol to improve the conditional integer-multiplication exponent kappa in T(n) = O(n (log n)^(1-kappa)). It guides researchers to establish the live frontier by reviewing READMEs, CONTRIBUTING.md, proofs, and witnesses, then reproduce the baseline in an isolated workspace with exact hashes. It then runs an evidence-driven search for plausible improvements, tests hypotheses with careful experiment logs, and independently certifies candidates using exact arithmetic and full verification. Finally, it packages the result with credits, licenses, and handoffs; AI assistance is disclosed; no unverified gains are claimed.

Blokkily is an experimental pattern-first DAW with a single event model that powers three synchronized editors—a tracker, piano roll, and step grid—driving a multi-track song. It provides CLAP/VST3 plugin support, real-time, allocation-free playback, and a canonical pattern-based workflow where edits propagate across views. A built-in LLM composition assistant can generate phrases via a prompt bar; the assistant runs on the GUI thread. It can be driven by an MCP agent to read sessions, write notes, control transport, and take screenshots. It supports streaming of large audio clips, tunings/scales in cents, MPE, and extensive undo/redo.

Janas-LLM is a pure-C toolkit that runs large LLMs on commodity hardware by streaming experts from an NVMe SSD while keeping weights off RAM. On a 32 GB-laptop, Qwen3-Next-80B runs at about 37 tokens/s (24 with drafts) and reads at about 62 tokens/s, versus llama.cpp’s ~2.8 tokens/s write and ~16 read. Janas-LLM beat llama.cpp on all 13 models tested in Q4_K_M. It supports CPU or GPU, with models converted to .jns; the project is experimental and designed for Linux and Windows, with speeds depending on hardware.

An unused Kindle was repurposed into a photo-frame controlled by an AI agent. The author built KindleCTL, a small app that cycles ten photos (four minutes each) and returns to books, using a GPT-6 Astra-powered setup after earlier attempts with GPT-5.6 Sol and others were blocked. They forked a SpiderCat jailbreak to run custom software on the Kindle via Wi‑Fi, developing tools to transfer files, diagnose errors, and implement a persistent feedback loop with remote screen captures. Most code is Python; launcher/slideshow in C. Photos stay on the device; offline use. It's a personal experiment, not a guide.

Intel GPU D270 is an inference-optimized data center GPU for agentic AI workloads. It supports long-context, high-concurrency inference with up to 480 GB LPDDR5X, 350 W, 32 Xe3P cores, and 256 XMX engines. It uses PCIe 5.0 and air cooling, fitting standard servers without liquid cooling. It’s open by design and compatible with PyTorch, vLLM, SGLang, and OpenAI Triton. Intended for AI platform architects and enterprises deploying production inference (RAG, enterprise assistants, coding assistants, multimodal models). Performance varies by use and configuration.

The Anton Anderson Memorial Tunnel in Whittier, Alaska, is America’s longest highway tunnel at about 2.5 miles. Built in 1943 during World War II, it links Whittier to the Alaska Railroad and Portage Glacier Highway, serving about 250 residents and acting as a vital transit artery to Anchorage. The one-way tunnel alternates traffic every 15 minutes and faces extreme winter conditions (temps to -40°F, winds to 150 mph). Toll: $13 round trip for standard vehicles; $22 for large vehicles. Best visited in summer; check schedule.

Brickbrag is a free browser game where players build, explore, race and fly in a shared brick town. No download or signup required; join online to shape a town built from bricks, with a race track, airfield, buses, shops and land you can own. Build alone or publicly; the Land Office sells lots and lets you own structures that others can’t knock down. Race tracks show live fast laps; hangars hold trikes; buses have robot drivers; travel through lava, mountains, forests and fields. Use WASD to walk, bricks to place, chat and gift with others.

An analysis claims an Intel FMA instruction vfmaddrnd231pd (VFMADDRND231PD) offering per-instruction rounding control via an immediate, enabling per-op rounding without AVX-512. The post notes the instruction is not recognized by assemblers or compilers (no intrinsics _mm_fmaddround_pd / _mm256_fmaddround_pd), and attempts to assemble fail with UD on Haswell. The 2024 SDM mentions vfmaddrnd231pd, but the 2026 edition omits it; DDS in VEX prefix appears undocumented and likely removed. The author suspects Intel planned the vfmaddrnd* set and removed it late, but docs weren't updated, and asks for confirmation.
