  • SlackwareARM in Cubieboard2

    From early this year I’ve been playing with an Allwiner SoC, the Cubieboard2 is a System on a Chip with 1GHz dual core CPU, 1GB RAM, 4GB NAND, 1 100MB Ethernet port, MicroSD card slot and a bunch of other niceties, expansion ports and what not.

Software developer, self-taught person, archer and amateur photographer. I like to share knowledge, also support and promote Free Software. Althought I am a loner kind of person, professionally I am good fit for teams, I work on Unix/Linux with several years of experience as full-stack developer. Hobbies I enjoy are reading, listen to music and play the guitar or the recorder, also hiking and camping.
