Michael Stapelberg


I use computers for fun and profit. In my spare time, I participate in the Free and open-source software community.


I wrote the Linux tiling window manager i3, the code search engine Debian Code Search and the netsplit-free, distributed IRC network RobustIRC.

Sometimes I dabble in electronics, for example with freetserv, my open hardware serial terminal server, or kinX, a low-latency replacement keyboard controller for Kinesis keyboards.

I used to be a Debian Developer, but these days I have effectively retired, aside from keeping services running. Instead, I like to publish Linux distribution research on the topic of fast package management.

My early adoptions are IPv6 and HiDPI, so I contributed patches to numerous programs (chromium, apt, radvd, vsftpd, etc.)


I sometimes give talks.
