Elizabeth Goldring's Holbein: Renaissance Master is a groundbreaking biography that situates Hans Holbein as a pragmatic, industrious craftsman whose portraits opened viewers to the sitter's inner nature. Tracing his Basel beginnings, move to England, and shift to royal service, Goldring notes his design work beyond painting and his role as a diplomatic asset for Henry VIII. The book links secular commissions to sacred-art conventions and shows how Holbein bridged reform-era art. It surveys lost works and potential portraits of More, Anne Boleyn, and Henry's brides. Richly illustrated, contextual, and highly praised, with minor factual errors acknowledged.

Cam Pedersen draws parallels between code and clay after a ceramics class with Kerri. Both are malleable mediums and vessels for ideas: centering clay, like writing code, is iterative and prone to wobbles, breaks, and reset. Before AI, every line was handcrafted; now LLMs can write much of the boilerplate, signaling an industrial revolution of code. Yet the craft endures: ceramics studios thrive, and personally meaningful, non-template ideas—like hypercubes—remain human. The author hopes to focus on such ideas while automation handles routine work.

Fly.io argues that read-only, ephemeral sandboxes are obsolete for code agents. They present 'Sprites'—durable, first-class computers in the cloud with rapid checkpoint/restore, 100GB start, and auto-idling to stay cheap. Sprites let developers run and persist full environments, install tools, and recover instantly from mistakes, enabling interactive work without rebuilding from scratch. The author contends stateless containers miss the needs of real agents (like Claude). The vision: replace sandboxes with disposable computers, because the age of sandboxes is over.

UK government will empower Ofcom under the Online Safety Act to compel encrypted messaging services to install “accredited technology” for client-side scanning, effectively scanning all messages on users’ devices before encryption for terrorism or child abuse material. Critics warn this ends end-to-end encryption and creates a digital panopticon, risking broader surveillance; Ofcom is due to publish a report by April 2026, followed by a consultation and swift Home Office action. If enacted, private messaging in the UK could be effectively surveilled and censored.

Eight processes explain all elements: 1) The Big Bang produced only the lightest elements; 2) massive stars explode (core-collapse) and forge many elements; 3) low-mass stars synthesize heavier ones via neutron captures (s-process); 4) white-dwarf explosions (Type Ia) enrich Si–Zn; 5) merging neutron stars (kilonovae) forge the heaviest elements; 6) cosmic ray spallation makes Li, Be, B; 7) radioactive decay yields various isotopes; 8) human-made elements beyond uranium are created in labs (Og). Neutron-star mergers help explain heavy elements, but may not account for all abundances; Big Bang alone cannot.

Ghostty’s largest memory leak was traced to the PageList memory management and a scrollback-pruning optimization. Ghostty uses standard pages from a pool and rare non-standard mmap pages. During pruning, the code resized non-standard pages to standard in metadata but did not shrink the underlying mmap memory. When freed, such pages were treated as standard and not munmapped, causing a leak. The fix: never reuse non-standard pages; destroy them (munmap) and allocate a fresh standard page from the pool. A macOS VM-tagging aid and a regression test were added. The fix is merged and due in 1.3 and nightly.

Worst of Breed is a satirical site lampooning resume-driven development and over-engineering. It parodies patterns like distributed monoliths and “Database as IPC,” touts a Tech Horror Radar of dubious technologies, and features mock quotes from execs praising bloated choices. Its manifesto proclaims Complexity over Simplicity, Process over People, Tools over Solutions, and Resume over Value, celebrating the very practices it mocks.

Alex Tardif argues that bindless rendering unlocks GPU-driven rendering with far less code and mental overhead. He contrasts the traditional CPU-bound draw loop with GPU-driven concepts—global buffers for constants, virtual texturing, megabuffers, and indirect/ExecuteIndirect draws—and shows how bindless descriptors let shaders index resources by ID, enabling event-driven draw management and scalable culling. He outlines practical patterns: store resources in tables, use compute shaders to generate draw arguments, frame-buffer descriptor updates, and read-only bindless access. Provides tips and references, aiming for bang-for-buck maintainable high performance.

An expansive, cross-cutting map of ideas shaping innovation, learning, and systems. It links cognitive biases (hindsight, self-deception), knowledge transmission (tacit knowledge, mentorship), reliability and design (redundancy, failure analysis, durability), and practical heuristics (first-principles thinking, OODA loop, intuition). It covers startup dynamics (pivoting, incentives, market feedback), social/political factors (coalitions, power, leadership), copying and open-source phenomena (collective brain, imitation), economics and technology cycles (creative destruction, standardization, entropy, monopoly risks), and core systems principles (Conway's Law, observability, openness). A taxonomy of patterns that drive invention, adoption, and failure.

Researchers filmed brown rats at Segeberg Kalkberg in northern Germany intercepting bats in flight for the first time, using infrared and thermal cameras (2020–2024). They documented 13 bat kills and 52 carcasses, suggesting deliberate predation rather than scavenging. The rats appear to balance at the cave mouth, catching aerial prey and also attacking bats crawling to roosts, implying two hunting strategies. The behavior may arise from the cave’s dense bat traffic and geometry, signaling adaptive predation by an invasive species, with potential negative effects on European bat populations. Management near large roosts is advised.

Good Judgment Open is a crowd-sourced forecasting platform that invites participants—especially Superforecasters—to predict major political, economic, and technological events. Sponsored by UBS Asset Management, The Economist, and Harvard Kennedy School, it features active challenges, featured questions, and an archive of open questions. Owned by Good Judgment, co-founded by Philip Tetlock, the service offers sign-in, registration, and a path to becoming a Superforecaster. Example forecasts include NYC mayoral race 2025, UN Security Council Gaza peacekeeping mandate, and US two-quarter streak of negative real GDP growth in 2025.

Vercel's v0 coding agent uses a three-part pipeline to boost preview-generation success: dynamic system prompts, LLM Suspense (streaming text manipulation), and autofixers (post-streaming fixes). The aim is to maximize successful previews; LLMs alone can have ~10% code errors, but the pipeline detects and fixes issues in real time, raising success rates. Dynamic prompts inject SDK-version-specific guidance via embeddings and curated samples; LLM Suspense shortens tokens and fixes imports on the fly, including icon handling. Autofixers patch code across files in under 250 ms. Together they deliver stable, high-rate first-pass renders.

An AI econ seminar simulates a hostile session where a presenter is grilled by four aggressive faculty (Dr. Chen, Roberts, Patel, Morrison) on topics from AI and labor-market inequality to tariff uncertainty and market microstructure. The presenter is pressed on assumptions, data, and validation, accused of intellectual theft or fraud, and ultimately admits a lack of rigorous proof and quits. The piece critiques the toxic economics-seminar culture and ends with a tongue-in-cheek warning: don't do an econ PhD, let the robots handle it.

Modal extends memory snapshots to GPUs using CUDA checkpoint/restore to capture GPU memory, CUDA state, kernels, streams, and mappings alongside CPU memory. Previously, GPU state had to be prepared after restore; now snapshots include GPU state, enabling startup with compiled artifacts and avoiding re-running torch.compile. This yields up to 10x faster cold boots across workloads (e.g., Parakeet with NeMo, ViT, Qwen). To use, set enable_memory_snapshot with experimental_options enable_gpu_snapshot in your app. Alpha availability; integrates with gVisor; thanks to NVIDIA CUDA and CUDA-Checkpoint project.
