Blog
Developer guides, tutorials, and tips on security, data formats, and more.
What the BeautiCode Blog covers
The blog is written by the same team that ships the tools — every guide exists because we needed the answer while building or debugging something real. Topics group into six buckets:
- Data formats — JSON vs YAML vs XML vs CSV, when to reach for each, how to convert safely, and what breaks at the edges (Unicode, nested arrays, streaming).
- Cryptography & security — password hashing (bcrypt vs SHA-256), HMAC, AES-GCM, RSA vs Ed25519, EIP-55 checksums, BIP39 mnemonics, TOTP.
- Encoding — Base64, URL percent-encoding, text encodings (UTF-8/UTF-16), when each one matters, common bugs.
- Frontend & performance — color math, SVG optimization, image formats, CSS minification, JavaScript bundling tradeoffs.
- DevOps & tooling — cron expressions, chmod/Unix permissions, Docker Compose, Kubernetes manifests, cURL and HTTP headers.
- AI generation — prompt patterns for image, icon, and text-to-speech workflows that ship well with small teams.
Each post averages 3,000–4,500 words and links to the BeautiCode tools that implement the technique so you can experiment immediately. New posts go up roughly weekly and surface at the top of the list below.
