Useful Information for RubyKaigi 2010 Attendees

Wi-Fi Internet Access

A free Wi-Fi Internet access will be provided at the conference venue. We will provide IEEE 802.11a and IEEE 802.11b/g access points in the conference rooms (Main Convention Hall, Convention Hall 200, 202-B, 202-A, 201-B and 201-A) and hallway. Because the network resources are very limited, please keep the following in mind:

The SSIDs for Wi-Fi access are "RK10-abg" (IEEE 802.11a/b/g) and "RK10-a" (IEEE 802.11a).

The encryption method for Wi-Fi access is set to WPA/WPA2 (personal) and AES. The password will be announced in the venue.

The outbound connections are restricted. Commonly used ports such as http, https, smtp, and pop3 are opened. Also, we are negotiating to open up some ports such as ssh, irc, svn, and git.

You can use Wi-Fi access that is provided by Tsukuba International Congress Center. However, it has more strict access policy.

Power outlets

We will provide power outlet spot around the entrance of the main convention hall.

There are a few seats with desks and power outlets in the main convention hall and convention hall 200. Please share with other attendees.

There are not enough power outlets for all, please share with others. If you plan to use your devices such as laptop computer, please consider brining extra batteries or such.

For attendees from outside of Japan, please keep in mind that domestic electricity in eastern Japan (including Tokyo) is 100V/50Hz. Most computer transformers can accommodate a wide range of voltages and frequencies, but please check to be sure. Most outlets will be for Japanese 2-pin flat blade plugs, although a limited number may be 3-pin flat blade plugs with a round grounding pin (North American). Please bring an appropriate adapter.
