I built a blog with Jekyll , I write technical posts and something about my daily life. I want to make my technical posts available to anybody but posts about myself only available to my friends for privacy. How can I achieve this?
With Jekyll itself, you can’t (barring some arcane JavaScript client-side encryption). You can use your webserver’s access control settings, though. If you use Apache, you can use the .htaccess file to protect a certain folder with a password. And then you would need to set up Jekyll to output the protected posts into this folder only.
