Websites
Sonomama (2008-)
A site that publishes an e-mail magazine for pregnant women. The website supports every Japanese mobile carrier, so
users can register and browse information for expectant mothers not only from a computer but also from a mobile
phone. As of November 2011, it had more than 120,000 users. During pregnancy it delivers a personalized message by
e-mail every day, and after childbirth it continues to deliver such messages at regular intervals. I built this
entire web system, including the message-composition program and the e-mail delivery program.
FlashBox (2004-2011)
A news site for Flash videos. It featured a rating system from the very beginning, and at its peak the site received
more than 50,000 page views a day. As video sites such as Nico Nico
Doga and YouTube emerged and demand for news sites declined, the
site was frozen at the end of 2011. I built this entire web system.
@links (2006-2008)
A service that automatically crawled web pages. Unusually for its time, it recognized each page's update frequency
and crawled pages at regular intervals. It was regarded as promising—for example, it was nominated for Web of the
Year 2006 [Web Information Source category] by Yahoo! JAPAN—but as RSS readers took over the market and the
maintenance cost no longer paid off, the service is now shut down. I built this entire web system.
@flabo (2007-)
A social networking service. Its distinctive feature was fine-grained control over who each diary entry was
published to, and, modeled on Twitter, it also included a mini-blog called "Hitokoto." Diary entries could
automatically crawl external blogs and turn their posts into entries, and there were features to cross-post diaries
to mixi and Hitokoto to Twitter automatically. The service aimed to let users manage the many SNSs that proliferated
at the time from a single place. I built the entire web system as it was at launch, but for maintenance reasons it
has since been switched to a program based on OpenPNE and has stepped back from the front line.
Ikeda: Human - Nature Coexistence (2002-)
The official website of Ikeda: Human - Nature Coexistence, a nature conservation group. Internally it runs on a
custom Wiki system, with features such as automatically moving event information to the archive once its date has
passed. I built this entire web system.
Module programs
iWord (Internal, 2009-)
iWord is a program that implements a high-speed version of the keyword-extraction
feature found in Hatena Diary. Within @freaks it is used not only to extract words, but also, for
example, to stop showing regular advertisements and display the company's own ads when a page contains harmful
words. Its core is written in C, and it is provided mainly as a PHP module. Because the dictionary data is kept in
shared memory, it needs no inter-process communication and performs no extra file reads or writes.
ImoLog (Internal, 2007-)
ImoLog is an Apache module for profiling that is built into every service in @freaks. It measures information such as the CPU time consumed by
each PHP program and compiles statistics. It measures not only CPU load but also transfer volume, providing
information such as which users are placing load on the servers.
