Among the talks I went to, I specially liked these two:
- MIST32: I was very impressed by the speakers of this talk. They have built an open source 32bit CPU called MIST32 on an Altera FPGA, and the corresponding Toolchain.
- FlashAir: this was a talk for encouraging developers to write applications for FlashAir. FlashAir is an SDCard with an embedded wi-fi web server. The web server has a CGI-based interface by which you can manage the files stored in the SDCard remotely. Lucky enough, I got a card in a lottery after the talk.
- Tokyo Hackers Space: Hackerspaces are community-operated physical places, where people can meet and work on their projects. I must say that soon after OSC2013, I became a member of Tokyo's hackers space!.
- Koedo Linux Users' Group: a group of Tokyo Linux users who publish their own magazine and organize meetings regularly.
- Firefox OS: I could finally touch by myself a smartphone equipped with Firefox OS. They told me that the Keon model can work in Japan with a Docomo SIM card.
