1. The 26,000-Year Astronomical Monument Hidden in Plain Sight
Total comment counts : 17
Summary
On Hoover Dam’s western flank lies Monument Plaza, a little-known installation featuring winged bronzes and a central flagpole. Its terrazzo floor functions as a celestial map marking the dam’s completion by the Earth’s 25,772-year axial precession—a 26,000-year clock the author ties to Long Now’s 10,000-Year Clock. Commissioned by the Bureau of Reclamation around 1931, the plaza remains poorly documented. The author contacts dam historian Emme Woodward, reviews artist Oskar Hansen’s opaque statement, and retrieves construction photos from the Bureau archives. Construction-era term for the site was “Safety Island,” and blueprints finally reveal the plaza’s plans.
Overall Comments Summary
- Main point: The discussion centers on a long-term star map/artwork meant to encode a date for future generations, its reported demolition, and what that implies for preserving such messages across millennia.
- Concern: The main worry is that practical issues or neglect could destroy or erase these long-term artifacts, undermining their purpose.
- Perspectives: The comments range from admiration for long-term timekeeping/art projects and support for the Long Now Foundation to skepticism about modern durability and curiosity about the science of celestial cycles and timekeeping.
- Overall sentiment: Mixed

3. Running Claude Code dangerously (safely)
Total comment counts : 67
Summary
The author uses Claude Code with –dangerously-skip-permissions, finding it efficient but risky for the host. Docker/containers and Docker-in-Docker complicate isolation. They instead sandbox Claude Code in a VM via Vagrant and VirtualBox, giving the agent sudo inside the VM while keeping the host safe. Shared folders work and a failed run can be wiped by restarting the VM. A VirtualBox 7.2.4 idle CPU bug is noted. The approach focuses on accident prevention rather than defending against sophisticated attacks, using a reproducible Vagrantfile for frictionless sandboxing.
Overall Comments Summary
- Main point: The discussion centers on how to safely run Claude-based agents through sandboxes, VM isolation, and controlled environments to prevent misuse while preserving productivity.
- Concern: The main worry is security risk—agents escaping sandboxes or causing unintended host changes—and the related user friction from permission prompts and complex setup.
- Perspectives: Opinions range from favoring strict VM/sandbox isolation to endorsing interception-based approaches and practical container/proxy workflows, with views shaped by whether the goal is agentic coding or safe task automation.
- Overall sentiment: Mixed
4. I’m addicted to being useful
Total comment counts : 54
Summary
Despite a tough time for software engineers, the author loves the job because it scratches an urge to be useful. He likens himself to Gogol’s Akaky Akakievich—an underpaid copyist who still finds meaning in work—arguing his own dysfunction fits the role. Many engineers are driven by internal compulsion to solve problems and control their output, rather than money or power. The piece offers ways to harness that impulse: protect time from predation, avoid frivolous ticket-crushing, and cope with working for people you may not respect. By broadening “technical problem” to include explanations and bug fixes.
Overall Comments Summary
- Main point: The discussion explores how software engineers experience meaning, usefulness, and burnout within corporate culture, and how to balance personal purpose with boundaries to avoid exploitation.
- Concern: Corporate environments can be toxic and exploitative, risking burnout and making self-worth hinge on work performance.
- Perspectives: Views range from caution about the dangers of being perpetually useful in toxic workplaces to stories of finding fulfilling, meaningful work and maintaining boundaries, with nuanced takes on motivation, relationships, ikigai, and different work arrangements.
- Overall sentiment: Mixed
5. Unconventional PostgreSQL Optimizations
Total comment counts : 8
Summary
This article explores unconventional PostgreSQL optimization techniques beyond standard indexing. It highlights constraint_exclusion, which lets the planner skip scans when constraints guarantee no results (useful for ad-hoc BI queries); it’s enabled by default only for partition pruning. Turning it on for all tables can increase planning overhead and may not help simple queries. It cautions against over-indexing, noting a 10-million-row sales table: a full datetime index speeds queries but uses ~214 MB. As a space-saving alternative, it suggests a function-based index on the date portion only, preserving reporting capabilities with less storage.
Overall Comments Summary
- Main point: Discussion centers on PostgreSQL features and their practical implications, particularly MERGE versus traditional upsert methods and related capabilities such as generated columns, hash indexes, and plan behavior.
- Concern: A key worry is that broad use of certain features (e.g., constraint exclusion) and PostgreSQL’s lack of plan caching can degrade performance on simple queries.
- Perspectives: Participants range from enthusiastic about new features and the MERGE option to skeptical about practicality, performance, and ecosystem integration.
- Overall sentiment: Mixed

7. Show HN: wxpath – Declarative web crawling in XPath
Total comment counts : 1
Summary
wxpath is an early-stage declarative web crawler that expresses traversal and extraction in XPath. You describe what to follow and extract in a single expression; results stream as soon as they’re discovered. It supports deep crawling via url(…) and ///, runs asynchronously (with a synchronous alternative), and respects robots.txt by default. Built on XPath 3.1 through elementpath, wxpath offers a CLI and Python API, a progress bar, and pluggable hooks. It supports caching backends (sqlite/redis) and a JSONL writer; docs note ongoing development.
Overall Comments Summary
- Main point: People are excited about XPath and a potential syntax extension, with a question about whether ‘/map’ refers to the HTML map element or a functional map.
- Concern: There is worry about whether the extension would be practical for general use and potential confusion over the meaning of ‘/map’.
- Perspectives: Viewpoints range from enthusiastic about XPath improvements to skeptical about general-use viability, with some seeking clarification on the ‘/map’ reference.
- Overall sentiment: Cautiously optimistic

10. Nvidia Stock Crash Prediction
Total comment counts : 36
Summary
The article analyzes whether Nvidia will close below $100 on any day in 2026. With the stock near $184, a drop would be drastic. It argues that a simple unbiased random walk is invalid due to time-scale and volatility: short-term moves are noise-dominated, while longer-term drift matters more. From 2025 data, the signal-to-noise ratio is −1.4 dB, so volatility matters. Instead of a fixed-walk model, it uses options markets to infer future volatility by pricing a December 2026 $100 call and back-solving for implied volatility. This approach yields about a 10% probability.
Overall Comments Summary
- Main point: Investors are debating whether Nvidia’s stock is sustainable in light of AI-driven GPU demand, heavy customer concentration, and potential shifts in supply and competition.
- Concern: The main worry is a material downturn or crash if AI datacenter spending slows, a few customers cut orders with little penalty, or financing/valuation dynamics unwind.
- Perspectives: Viewpoints span bearish concerns about cyclicality and concentration to bullish views on enduring demand, the CUDA/software moat, and new products, with additional caveats about competition, used hardware markets, and geopolitics.
- Overall sentiment: Mixed
