Popular guides
Long-form explainers that answer common questions and link back to the matching tools.
- How to create a strong password (and store it safely)Length beats complexity theater. Learn what makes a password strong, how browser generators help, and why a password manager matters.
- What is Base64 encoding? (and when not to use it)Base64 turns binary or awkward text into ASCII-safe strings for APIs and data URIs. It is encoding—not encryption.
- How to format and validate JSON before you ship itBeautify JSON for reading, minify it for transport, and catch trailing commas or quote mistakes early.
- Unix timestamps explained: seconds, milliseconds, and time zonesLearn what Unix time is, how to tell seconds from milliseconds, and how to convert timestamps when debugging APIs and JWTs.
