Probably a Blog

This blog has been dormant for quite some time. The last post was back in 2016, and the whole setup was running on Hexo 3.1.0 with FTP deployment.

And the search goes on and on, up to the point where I promise myself that if I somehow manage to pull this off I’m going to blog about it. And here it is, the simplest way I find to create a “hole” on an android view.
