• TecMint ☛ Create a Self-Signed SSL Certificate for Apache on Rocky Linux 10

  Many older tutorials still use a basic openssl req -x509 command to create a certificate.

Without it, visitors will see errors like ERR_CERT_COMMON_NAME_INVALID, even if the certificate’s Common Name appears correct.

• Alex Chan ☛ Rendering a chat thread in CSS and JavaScript

  I always try to use semantic HTML when I can, and lean on the browser’s default styles – they’re a solid baseline and give me a bare minimum even if my CSS breaks. I dislike the approach of many CSS frameworks to reset the browser styles and rebuild them from scratch.
