Out of Light Adjust Share: Caravaggio, La Tour, and the Art of Attention

Nicole Krauss reflects on how light and darkness in Caravaggio and Georges de La Tour reveal how attention—focused, devotional looking—transforms perception and elevates the ordinary into the sacred. Through a Rome year, a Tuscan hillside, a beach near Porto Ercole, and museum visits, she links illumination to moments of grace, memory, and identity, arguing that art's lighting not only illuminates but teaches us to see. She contrasts Caravaggio's dramatic chiaroscuro with La Tour's candlelit tenebrism, suggesting "the gift of attention" renews how we inhabit light and life.

Even the Mars Rover Uses Zip Ties (2021)

Perseverance uses ABB Ty-Rap zip ties made of ETFE resins, which withstand about 2,000 times more radiation than nylon and extreme heat. They secure hoses and wires on the rover; Ty-Rap ties have also been used on Curiosity, Spirit, and Opportunity. ABB notes these high-performance ties have operated in the harshest conditions for decades. The piece riffs that if NASA trusts zip ties, they're fine for your Civic, and a 100-pack is available from Home Depot for under $30.

Writers and Their Day Jobs

Ed Simon surveys the long-running tie between labor and literary life, arguing that writing is both work and vocation. He recounts Herman Melville, who, after Moby-Dick’s tepid reception, spent nineteen years as a U.S. Customs Inspector while composing. The essay maps other writers who held ordinary jobs—Faulkner as a postmaster, Bukowski as a carrier, Kafka in an office—often feeding their art from the drudgery of daily work. Simon also shares his six months at the USPS, contending that many writers endure ‘bullshit jobs’ yet pursue writing’s privileged calling.

What Pressure Does to an Athlete's Body

Pressure isn’t abstract—it triggers real biochemistry that reshapes performance. Stress redirects blood flow, increases muscle tension, and distorts proprioception and ‘muscle sense,’ undermining fine control on skates and boards. Neurotransmitters and hormones—acetylcholine, dopamine, norepinephrine, cortisol—compose the brain-body choreography that can derail or sharpen a moment. The piece profiles Mikaela Shiffrin, Ilia Malinin, and Alysa Liu: the first learned to manage anxiety through sleep, breathing, psychology; the second struggled with nerves; the third found relief in a carefree approach culminating in gold. Training, rest, reframing, and mental prep beat pressure.

I don't know how you get here from "predict the next word."

John H. Cochrane tried Refine, an AI tool, to critique his inflation booklet and was impressed by the quality and conciseness of the feedback. The AI’s comments focus on operationalizing the fiscal news narrative, clarifying the FTPL vs NK regime, and reconciling transmission mechanisms with specific dates and observable data. It also found algebra errors. Cochrane foresees AI transforming refereeing and editors’ workflows, while warning about embedding results in LLM training and potential consensus bias. He plans to continue using Refine.

An autopsy of AI-generated 3D slop

The piece argues AI-generated 3D models are not usable for serious e-commerce. Comparing an AI-generated paddle to a handcrafted one reveals AI artifacts: chaotic triangle topology (triangle soup) hindering editing; texture hallucination with baked lighting and illegible branding; unusable UV maps. It also debunks “time savings”: despite a small file, practical efficiency is worse because retopology and texture fixes are needed, often longer than starting from scratch. Conclusion: human 3D artists are still essential for reliable edge flow and editable, PBR-ready textures; AI may only be suitable for distant background assets for now, with future improvements possible.

Show HN: OpenSwarm – Multi‑Agent Claude CLI Orchestrator for Linear/GitHub

OpenSwarm is an autonomous AI agent orchestrator that coordinates multiple Claude Code CLI agents to autonomously process Linear issues through a Worker–Reviewer–Tester–Documenter pipeline, with progress reported to Discord and long-term memory via LanceDB embeddings. Its architecture includes a central Linear API, DecisionEngine, TaskScheduler, and a knowledge graph, plus a Discord bot and a web dashboard. It requires Node.js 22+, Claude Code CLI, and API keys. Install by cloning, installing, configuring config.yaml/.env, and running in dev or prod. It stores state under ~/.openswarm and supports Docker.

Google API keys weren't secrets, but then Gemini changed the rules

Truffle Security reports that Google API keys—historically seen as non-secret identifiers—can now act as Gemini credentials. When the Gemini Generative Language API is enabled, existing keys (even in public frontend code) can access Gemini endpoints, causing retroactive privilege escalation and insecure defaults (Unrestricted by default). They found 2,863 live keys on the public Internet, including Google's own, able to read uploaded data and incur AI charges. Recommendations: audit GCP projects for the Generative Language API, inspect and rotate keys, ensure none are public, and scan with TruffleHog. Google's roadmap includes scoped defaults, leaked-key blocking, and proactive notifications.

Turns out Generative AI was a scam

Gary Marcus argues generative AI is unreliable and far from artificial general intelligence. He cites Shira Ovide’s Washington Post critique showing hype about AI driving GDP growth was overstated and insufficiently scrutinized. LLMs still hallucinate, err, and deliver low-quality work; a Remote Labor Index suggests they handle only a tiny fraction of human tasks. While niche uses exist (coding), the overall economic impact is likely smaller and potentially harmful: strains on education and information ecosystems, environmental costs, mental-health risks, nonconsensual deepfakes, and inflated investor/policymaker expectations.

RAM now represents 35 percent of bill of materials for HP PCs

HP says RAM now accounts for about 35% of its PCs' bill of materials, up from ~15–18% last quarter, driven by a memory shortage and price hikes. RAM costs rose ~100% sequentially and are expected to rise further, pressuring HP's Personal Systems margins. HP anticipates a double-digit decline in its total addressable market this year. To cope, HP raised PC prices, offered lower-RAM configurations, added suppliers, sped material qualification, and cut logistics costs with AI planning. Personal Systems revenue grew 11% YoY to $10.3B (consumer +14%, business +11%).

Tech Companies Shouldn't Be Bullied into Doing Surveillance

A Department of Defense ultimatum pressures AI company Anthropic to expose its technology for military use without restrictions, threatening to label it a “supply chain risk” if it refuses. Anthropic has publicly refused to allow two red lines—surveillance of US persons and autonomous weapons. The piece notes the controversy began after a Palantir partnership and Anthropic’s safety stance, arguing that government pressure shouldn’t override civil-liberties commitments. It urges tech firms to resist becoming tools of surveillance and to stay true to their stated principles.

Jane Street Hit with Terra $40B Insider Trading Suit

A U.S. lawsuit filed February 23 accuses Jane Street Group LLC of insider trading tied to Terraform Labs’ $40B Terra-Luna collapse. Terraform withdrew 150 million TerraUSD on May 7, 2022; within 10 minutes Jane Street allegedly pulled 85 million TerraUSD from Curve3pool, described as a turning point that shattered TerraUSD’s peg. The complaint—brought by Todd Snyder, the Terraform bankruptcy administrator—alleges use of non-public information via a back-channel with Terraform staff, including Bryce Pratt; defendants include Do Kwon and others. Jane Street calls the suit baseless; the case echoes Jump Trading concerns and crypto-insider trading complexity.
