Flair in Octopress via HTTPS

| Comments |


I replaced the big avatar of my self intro in the sidebar with my Stack Exchange flair, which summarized my reputation and badges on Mathematics Stack Exchange. Since then, it’s easier to see my profile there.


When I browsed my blog, I saw a lock with a yellow triangle on the left of the URL.

</source> An abnormal icon on the left of the URL

This indicated the presence of insecure contents.

</source> </source> Firefox's error console message

How can I get rid of this error message?


Even though I focus on math analysis now and I’m not going to write any programming code, the advice of this article about programming still applies. Reading the error message, I recalled one of my old posts written more than one year ago. It was titled MathJax in Octopress via HTTPS. Therefore, the only thing that I needed to do was to add an s between http and : in the URL of the image for the flair.

A command learnt

I typed the command git log -g --grep "flair" in the repository for this blog, and I quickly see the results.

    Changed the picture on the RHS in self-intro
    Replaced the avatar with a flair so that it's more convenient to view my
    Stack Exchange profile.

Unluckily, the normal flags in the grep utility aren’t supported, say the case insensitive search.

P.S. I replaced my email with to avoid junk mail. If you fork any one of my repositories on GitHub, you’ll know what it is.
