The content argues against the widely accepted notion that JSON cannot contain comments, as stated by Douglas Crockford. The author suggests that comments can be included in JSON files as long as they are read by a parser that can handle them. The author emphasizes that custom parsers can be designed to accept comments without causing issues, provided the JSON is not coming from untrusted sources. While acknowledging the existence of alternative formats like json5 and jsonc, the author believes they are unnecessary, since regular JSON parsers

Passwords remain a widely-used method for authentication, despite the advancements brought by Single Sign-On technologies like OAUTH and SAML. When implemented correctly, passwords can be secure, but many systems fail to handle them properly. Common mistakes include inadequate maximum password lengths, which can indicate poor security practices, such as storing passwords in plain text rather than using proper hashing methods. Proper password hashing should utilize cryptographically secure hashing functions that are computationally intensive to reverse, making it difficult for attackers to deduce the original
