title: Why GitHub shows someone else commit to my repository but it was done by myself?
body: <p>I committed as usual to my remote <a href="https://github.com/ComplicatedPhenomenon/Fortran_practice" rel="nofollow noreferrer">repository</a> on GitHub, but recently I found after my committing, it shows that was being done by another people. It is weird and I don't know why.</p>
