Hi, my name is Koji Tanaka(@kojiwell). I use open source software to live life in peace. I like the culture of open source. I guess I want to be part of it. I build up (and sometimes break down, and then rebuild) high-performance computing systems. I also help users get the most out of the systems. When I’m not working or sleeping, I’m hanging out with my family or friends, reading a book, running, or freediving. And when I’m not doing any of those, I’m probably writing bits and pieces here. So this place is for a collection of the stuff I’ve learned along the way as a system guy.
