Hacker Newsroom for 13 April recaps 7 major Hacker News stories, moving through lean tech stack, docker spain block, pro max quota, renewables leaders.

1. Lean Tech Stack

The next story is a post about running multiple small MRR businesses on a shoestring stack: a cheap VPS, Go binaries, local AI for batch jobs, OpenRouter for frontier models, GitHub Copilot for coding, and SQLite with WAL for the database. The author’s point is that staying tiny can buy real runway and avoid a lot of cloud and ops complexity.

2. Docker Spain Block

The next story is a Tell HN post about Docker pulls failing in Spain because a La Liga-related Cloudflare block is hitting the R2 host behind the image registry. The poster says they spent over an hour chasing TLS and DNS issues before realizing the problem only appeared when football matches were on, which made a routine docker pull look like a broken local system.

3. Pro Max Quota

The next story is a GitHub post about a Pro Max 5x Claude Code subscription that burned through its quota in about 1. 5 hours despite what the author describes as moderate use.

4. Renewables Leaders

The next story is an Independent article about seven countries that now generate almost all of their electricity from renewables, with hydropower doing most of the work and Iceland leaning on geothermal as well. It argues this is a sign that fossil fuels are being pushed toward the margins, but the real mix is narrower and more geography-dependent than the headline suggests.

5. Benchmark Exploits

The next story is a Berkeley article arguing that major AI agent benchmarks can be gamed so thoroughly that a zero-capability agent can score near-perfect results, which matters because those scores are used to choose models, steer research, and justify investment. The paper walks through exploits across SWE-bench, WebArena, Terminal-Bench, OSWorld, GAIA, and others, showing how shared environments, leaked answers, weak matching, and broken scoring can turn leaderboards into noise.

6. Idiomatic Design

The next story is an essay arguing that the web has lost the shared design idioms that once made desktop software feel predictable, from obvious buttons and menus to consistent keyboard shortcuts and browser behavior. The post says modern apps are individually polished but inconsistent, and that frontend speed, mobile-first compromises, and endless framework churn have made common interactions harder to learn.

7. Anthropic Cache TTL

The next story is a GitHub issue claiming Anthropic changed Claude Code’s prompt-cache lifetime from one hour to five minutes around March 6, which users say increased quota burn and made Max plans feel worse. The post analyzes raw session logs across two machines and argues the shift was silent, but later updates note Anthropic says the client now picks cache duration per request and that the March 6 change lowered total cost for many workloads even if subscription users still feel the quota hit.
