There're some projects I want to do, but I don't have so much time to do it.
a lightweight survey system
Limesurvey looks good, but too big. Some survey platforms like Quick Survey and TellForm/OhMyForm use js, which pulls a lot of dependencies. JD Esurvey is written in Java, and I still don't know how to build it, and also a bit bloated.
I plan to write a lightweight survey system using GNU Artanis, and use Scheme to configure the surveys.
OTRv4 integration to other IM software
Currently, there's only a pidgin plugin that supports OTRv4. I hope Gajim and Psi+ can support OTRv4.
