I am an FLOSS developer; at times I write blog and my novel (both in Chinese). I develop some apps and softwares for fun and/or personal use (at least initially).
I believe the world needs to be more open, internets (yes, not only the Internet) needs to be inter-connected and federated, people's privacy should remain protected.

Some softwares developed by me:

Easer Easer-logo

Easer is an event-driven Android automation tool. It knows various events and you (the user) could tell it what to do on what event (and even combine multiple events). Routine actions no longer need to be manually taken.

Events can be chained as trees in Easer -- this allows Easer to (somewhat) organize Events using boolean logics ("and", "or").

The ability of listening to and sending out any user-defined broadcasts makes Easer a hub of adjusting interoperation between any apps.

CamCov CamCov-logo

CamCov uses your (rear) camera as background on your phone -- no matter what app your are currently using.

FLock FLock-logo

FLock shows a floating button (on top of any screen) to lock your screen. Long pressing can trigger a customizable broadcast.


Python re-written of pacman-ps -- list the "outdated" files in memory after software update by pacman (the package manager of archlinux). The function is similar to yast ps.
