Guides
Reusable technical guides for the tools and topics on ilham.dev: debugging, configuration, data formats, security, networking, documents, and everyday developer workflows.
Guides are reusable explanations. They sit between the interactive tools and the personal posts: practical enough to use, but not tied to one specific story.
- API Testing
Using OpenAPI files, mock responses, webhooks, gRPC testers, and request tools without copying blindly.
- Browser Debugging Utilities
Device info, network info, key codes, microphones, cameras, JavaScript playgrounds, and browser-side testing.
- Browser File Tools
Small browser-side file tasks such as zip creation and Base64 conversion, with privacy boundaries.
- Browser Games and Practice Tools
Small browser games and practice utilities that live under tools without becoming blog posts.
- Calculators and Unit Conversion
Percentages, discounts, loans, interest, unit prices, currency, temperature, fuel economy, number bases, and roman numerals.
- Dates, Timestamps, and Time Zones
Dates, durations, timestamps, time zones, age calculations, stopwatches, and ETA estimates.
- Debugging CORS Without Guessing
A practical way to reason about CORS errors, preflight requests, credentials, and browser behavior.
- Docker Basics
Dockerfiles, Compose conversion, logs, and the small container details that matter during development and ops.
- Email Debugging
Email headers, normalized addresses, suspicious messages, and the limits of what email metadata can prove.
- Filtering Docker Logs Effectively
How to filter Docker container logs without losing useful context, timestamps, and failure clues.
