Thousands of arid but potentially fertile acres needed only water to become the Imperial Valley of the Northwest. Locked in the mountain ranges were valuable ores awaiting electricity to turn them into needed metals. Two years later the State engineer of Oregon urged the development of the Bonneville site as a national-defense measure: he saw in the proposed power project a source of fertilizer in…

🔥 Discover this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: One thing I was (and still am) worried about when it comes to my recent big interactive essay is that by showing all these classic desktop examples, the whole thing might appear old-fashioned, relevant only to a bygone era. Yet, the challenges it shows are universal. Here’s something I just spotted. This is how you rotate an image on an iPhone and on a Nothing Phone: It’s a pretty standard control – tap once to rotate counterclockwise, tap a second time to do it again,…

0 CommentsEntertainment

💥 Explore this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: A few weeks ago, I wrote about a rising and extremely prolific marketing scam that I’ve been able to trace back to operators in Nigeria. Using highly personalized (AI-generated) email solicitations that make it seem the sender (always with a Gmail address, always presenting as a marketing or PR expert) has really read the book, the scammer offers marketing services of various kinds, usually for a not-exorbitant fee of a few hundred dollars. If the author bites, they’re referred to a Nigerian “assistant” or “payment…

Many bacterial species resist cleaning chemicals and cling to sterile surfaces by producing sticky films in NASA's cleanrooms. Credit: NASA/JPL-CaltechNASA’s cleanrooms are sterilised by reducing humidity, through intense cleaning, and radiation exposure. Yet, some microbes persist in these rooms, an international research team has found1. The team has identified 26 new bacterial species in the cleanrooms where the Phoenix Mars Lander was assembled before its lift-off. The team, which included researcher Karthik Raman at…

GPT-5.5 Codex reasoning-token clustering at 516/1034/1552 may be leading to degraded performance on complex tasks · Issue #30364 · openai/codex · GitHub

0 CommentsEntertainment

✨ Check out this insightful post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Summary I found an aggregate pattern in Codex token_count metadata: gpt-5.5 responses disproportionately land at exactly reasoning_output_tokens = 516, with additional fixed-boundary spikes around 1034 and 1552. This appears model-specific and coincides with lower overall reasoning-token intensity, which may help explain degraded performance on complex/high-stakes Codex tasks. This is related to #29353, which reported a task-level reproduction where gpt-5.5 runs ending at exactly 516 reasoning tokens returned the wrong answer. This issue adds aggregate evidence across a larger Feb-Jun window. I am not claiming…

Better Models: Worse Tools | Armin Ronacher’s Thoughts and Writings

🔥 Explore this trending post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: written on July 04, 2026 A very strange Pi issue sent me down a rabbit hole over the last two days. The short version is that newer Claude models sometimes call Pi’s edit tool with extra, invented fields in the nested edits[] array. And not Haiku or some small model: Opus 4.8. The edit itself is usually correct but the arguments do not match the schema as the model invents made-up keys and Pi thus rejects the tool call and asks to try again. That…
