Operation of CTF Contests

I'm an initial member of tkbctf operation team. Mainly I am in charge of development/maintenance of a score server (earth/parasol). (Note that tkbctf is an unofficial contest, so there is no relationship with the university authorities.)

tkbctf2 (on September 29th, 2013) in charge of developing a score server, making a challenge: SkillAnalyzer

Twitter bot (not working now)

I created Twitter bot, @meitanbot. It generates the text by replacing nouns. This idea is from Reudy (Society for the Study of Botics, Tokyo Tech)
