Searchable guide pages
High-interest topics like UUIDs, JWTs, Base64, and PDF handling live on their own indexable pages with tighter keyword focus.
Overview
Why this hub exists
Search engines and reviewers respond better to pages that explain real decisions and trade-offs, not just blank forms. This hub routes traffic into focused guide URLs and then back into working tools.
Bridge guides and tools
Every guide links into an actual utility page so explanation still leads straight into action.
Quality before ads
For now, the site prioritizes useful content and crawl quality over ad loading, which is the safer direction while review status is still sensitive.
Guide Library
The guides worth reading first
UUID v4 vs v7
When random IDs are enough, when time-ordered IDs help, and how storage choices affect operational work.
JWT exp / nbf
How expiry claims are misread in practice and why validation context matters more than people expect.
Base64 vs URL encoding
They both transform strings, but they solve different transport problems and fail in different ways.
PDF merge / split
When to combine documents, when to extract ranges, and where browser-side PDF processing helps or hurts.
AI Coding
Claude Code and Codex now have quick references too
People re-open AI coding tools for the same command names and settings over and over. These pages summarize the official docs and link straight back to the sources.
AI coding cheatsheet hub
A fast entry point for deciding which reference page to open first based on the problem in front of you.
Claude Code cheatsheet
A quick page for slash commands, MCP, hooks, and project command locations.
Codex cheatsheet
A compact reference for CLI flags, /mode, /personality, Skills, Automations, and key settings.
Use It Well
How to use the hub well
- Start with the one guide that matches the problem you searched for, then jump into the linked tool page immediately.
- Most debugging flows move across layers, so it helps to combine conversion, time, PDF, and meta-tag tools instead of staying on one page.
- For fast-moving topics like AI coding tools, use the cheatsheet first and then jump out to the official docs once you have the right keyword again.
Policy
Current operating direction
- Until ad approval is cleared, the live site favors crawl quality and useful content over loading ad scripts.
- Tool pages stay fast and compact, while search-friendly topics get their own explanation pages.
- The hub, the standalone guides, the cheatsheets, and the tool pages all link into each other so indexed pages can still drive real usage.
