Developer builds Clash Royale stats site that hides win rates with under 30 samples

·1 views

A developer behind Royale Cards, a Clash Royale guide site, has shared lessons from building a small static site hosted on Cloudflare Pages that prioritizes data transparency. The site enforces a strict rule: win rates are only displayed when at least 30 battle samples exist, with a 'sample too small' note shown otherwise. Each of the roughly 133 card pages covers stats across all 14 levels, arena unlock info, and top deck combinations, keeping pages focused for both search engines and mobile users. For the current K.H.A.O.S season, the site clearly separates officially confirmed facts from editorial analysis, helping readers distinguish between the two. The developer's key takeaway is that being upfront about data limitations is a genuine differentiator for niche stats sites.

How Claude Code's PreToolUse Hooks Can Block Dangerous Shell Commands

Claude Code's ability to run tools introduces risk, as prompt-based instructions alone can be unreliable guardrails. Developers can use a PreToolUse hook — a script that runs before any tool call — to programmatically intercept and block dangerous commands like 'rm -rf'. The hook works by inspecting incoming Bash commands and returning exit code 2 to block execution, while exit code 0 signals no objection. A sample implementation uses a shell script paired with a settings.json configuration file placed inside the project's .claude directory. Developers are cautioned that hooks are a supplementary safety layer and should be combined with permission rules, sandboxing, and backups for high-stakes environments.

Developer corrects a 'never published' status field — only to find the article was already live

A software developer writing about stale status fields in documentation made the very error they were cautioning against. While reviewing a drafts folder, they misread a YAML front-matter flag — 'published: true' — as a historical record rather than a build instruction, and confidently marked the article as never published. The article had in fact been live for over a day on a separate platform, a fact recorded in the team's own backlog file. The mistake was only caught when a duplicate-post attempt returned a 'title already exists' error. The developer noted that a confident correction, made with less verification than the original claim, can be more misleading than the ambiguous field it replaces.

Codename One Adds Portable Routing API to Simplify In-App Navigation

Codename One, an open-source framework for building cross-platform apps in Java or Kotlin, has introduced a new routing module via pull request #5480. The update adds a com.codename1.maps.routing package that models road geometry, waypoints, distances, durations, and encoded polylines. Developers can use a simple two-line call for basic route display or a callback-based API for advanced needs like ETAs, alternatives, and custom styling. The default routing backend is the open-source OSRM demo server, which requires no API key but is not intended for production use. The design abstracts the service layer so application code works with a standard Route model regardless of the underlying routing provider.

GitHub Combines Admin UI and Billing API to Help Orgs Control AI Spending

GitHub administrators can use the Metered Usage dashboard alongside the Billing Usage API to investigate and manage rising AI costs more effectively. The Admin UI allows admins to identify spending increases by period, organization, or cost center within a few clicks. The Billing Usage API complements this by enabling reusable, automated reports tailored to a company's specific reporting needs, such as finance calendars or team-level breakdowns. Together, the two tools help admins pinpoint whether a spending spike is broadly distributed or concentrated among a few users before applying any restrictions. The goal is to protect productive workflows while addressing unexpected cost drivers through targeted budget controls.
