About:
My name is Mariusz Zaborski, also known as oshogbo. I’m a Polish software developer. My main areas of interest are OS security, low-level programming and fileystems.

In my free time, I contribute to the open-source community. I have been a FreeBSD committer since 2015. My primary work in this project is focused, but not limited to, creating infrastructure around Capsicum - process sandboxing technique based on capabilities. I was also a successful student of the Google Summer of Code 2013 for this project. In the past, I was a team member of vexillium group, a group of computer enthusiasts. We participated in some GameDev competitions with notable success. Unfortunately, the group is no longer active. I also organized two mettups: the Polish BSD User Group (BSD-PL, since 2018), and a security meetup - No Such Meetup (since 2019). Unfortunetly, both project were canceled due to COVID.

Besides this blog I also like to share my experience and work at conferences. I was a speaker at a number of BSD and security conferences. I also wrote articles for some international and local magazines.

I live in Warsaw, a big capital city in Europe.
