有一些几句话就可以说明白的观点或者解决的的问题，小虎单独收集到这里。

Commits没有算入每天的activity

fork的仓库是不算的。
Commits made in a fork will not count toward your contributions.

Contribution activity not shown for github page

移除已忽略的文件Remove ignored file in .gitignore

The rules in your .gitignore file only apply to untracked files. Since the files under that directory were already committed in your repository, you have to unstage them, create a commit, and push that to GitHub:

git rm -r --cached your_file
git commit -m 'Remove the now ignored file'
git push origin master
