Spain blocks prediction markets Polymarket and Kalshi over lack of gambling licence

940 points · reuters.com

Spain’s gambling regulator has ordered ISPs to block access to Polymarket and Kalshi after ruling both platforms operate as unlicensed bookmakers under Spanish law. The move is the most aggressive crackdown yet on the prediction-market category in Europe, and it lands while both companies are pushing hard for mainstream legitimacy in the US. HN is debating the usual question — are these markets “gambling” or are they information aggregators that happen to use real money — but the regulator clearly came down on the gambling side, and other EU jurisdictions are watching.

Dropbox CEO Drew Houston to step down

352 points · cnbc.com

Drew Houston is handing the keys to Ashraf Alkarmi, ending an 18-year run as founder-CEO of one of the original consumer-cloud unicorns. Dropbox’s stock has been range-bound for years as Box, Google Drive, and OneDrive ate into the file-sync market and the company struggled to find a second act in AI-powered productivity. The comments are part nostalgia, part autopsy — including the perennial “imagine if they’d taken the Steve Jobs acquisition offer” — but several engineers also point out that Dash and the AI document features have been quietly competent, just not enough to move the needle.

Cloudflare Flagship

236 points · developers.cloudflare.com

Cloudflare has rolled out Flagship, a new top-tier developer offering that bundles Workers, R2, D1, Durable Objects, and the rest of the edge-compute stack with higher limits, dedicated support, and what the docs describe as “production-grade SLAs for AI inference workloads.” It’s a clear push to position Cloudflare as a credible Vercel-and-AWS alternative for teams building agentic and inference-heavy applications. HN engineers are picking apart the pricing and noting that the real test will be whether Workers’ cold-start story holds up under serious LLM traffic.

That Methyl Methacrylate Tank

336 points · science.org

Derek Lowe’s “In the Pipeline” digs into the recent industrial accident involving a methyl methacrylate storage tank, walking through the chemistry of why these tanks can run away catastrophically if the polymerization inhibitor depletes. The post is a small masterclass in why process safety isn’t just paperwork — MMA is exothermic enough that a stalled inhibitor system can take a tank from “fine” to “rupture” in hours. HN’s chemistry-curious crowd is using the thread to swap stories about other reactive-monomer near-misses.

A few interesting modern pixel fonts

361 points · unsung.aresluna.org

A loving tour of contemporary pixel fonts — not the nostalgic 8-bit clones, but new typefaces designed from the ground up for tiny grids and modern displays. The post highlights the surprisingly subtle craft involved in making 5×7 glyphs that are both legible and have personality, and includes downloadable specimens. It’s hit a nerve with HN’s design-aware programmer set, and the comments have become a de facto roundup of every nice pixel font people have stashed in their ~/.fonts directory.

The worst job interview I ever had

355 points · oliverio.dev

A senior engineer recounts a multi-round interview process that went off the rails — from a hostile interviewer who turned the call into a debugging trap, to a take-home that mysteriously expanded after submission, to a final “alignment chat” that became a salary negotiation in bad faith. The piece is striking less for any single horror story than for how recognizable each beat is. Comments are full of “I had the same thing happen at $COMPANY” recognition, plus a healthy debate about whether the tech-hiring market has gotten meaner or just always was.

I built a Git-tracked book production pipeline

245 points · djspeckhals.com

An author and engineer documents how he replaced his InDesign-and-Word workflow with a fully version-controlled pipeline built on Markdown, Pandoc, LaTeX, and a small army of Make targets. The result is reproducible PDFs, ePubs, and print-ready files with every change tracked in git, plus diff-able prose review. It’s a niche but lovingly detailed writeup, and HN’s writers and self-publishers are mining it for ideas — particularly the bits on managing footnotes, figures, and cross-references at scale.

Launch HN: Minicor (YC P26) — Windows desktop automations at scale

91 points · minicor.com

Fresh out of YC’s Provisional 2026 batch, Minicor is pitching enterprise-grade Windows desktop automation — think RPA, but built around modern AI agents rather than brittle screen-scraping scripts. The launch post and HN thread emphasize their use of vision models to handle UI drift, plus a control plane for managing thousands of headless Windows VMs. The comments are split between people who’ve been burned by UiPath-era RPA and people who think LLM-driven agents finally make this category work; either way, it’s a useful data point on where the agentic-workflow wave is going.

Claude Code as a Daily Driver: Claude.md, Skills, Subagents, Plugins, and MCPs

77 points · arps18.github.io

A deep, opinionated walkthrough of how one developer has wired Claude Code into his everyday workflow — covering CLAUDE.md conventions, custom Skills, multi-agent orchestration, plugin authoring, and connecting external services via MCP. It’s the kind of post that reads as both a tutorial and an argument: that the productivity ceiling for AI coding tools is largely about how much scaffolding the user is willing to build. HN engineers comparing notes on Claude Code, Cursor, Aider, and Cline are using it as a reference point.

Rosalind: A genomics toolkit in Rust running whole-genome pipelines on a laptop

159 points · github.com/logannye/rosalind

Rosalind is a from-scratch Rust implementation of common bioinformatics primitives — alignment, variant calling, k-mer counting — designed to be fast enough to run end-to-end whole-genome pipelines on a single laptop. The project leans hard on memory mapping, SIMD, and Rust’s parallelism story to avoid the usual “spin up a cluster” tax. Comments from working bioinformaticians are cautiously enthusiastic: the benchmarks look real, but the question of whether it can supplant the entrenched C/C++ tooling (samtools, bwa, GATK) is the usual uphill battle.
