Earthquake

M 4.9 earthquake hit us during our work at the summit (of Mauna Kea). We’ve just started moving our instrument from fixed points at that time, and could not understand what was happened.
Since it was not so large, no serious damage we’ve got. (Other than snow falls recent days. lol.)

Getting X’s windows from remote hosts on Cygwin/X

As previous, I think we can get remote X’s windows simply via ‘ssh -X’ or ‘ssh -Y’ with using ‘DISPLAY=localhost:xx.0’. But I cannot do so now.

For this problem, I’ve first searched ‘xhost’ command, but cygwin returns ‘xhost: Command not found’. So, I’ve changed to other way with using pure xauth method.

On cygwin terminal, you’ll get the followings with xauth command.

% xauth list
hostname:0 MIT-MAGIC-COOKIE-1 091fcf131a5c647869f2f4d5bf45e26c
hostname/unix:0 MIT-MAGIC-COOKIE-1 2554c8810c6218f08fec1f1e63599d09
10.0.0.25:0 MIT-MAGIC-COOKIE-1 2554c8810c6218f08fec1f1e63599d09

The last hex value is the COOKIE of X, and might vary on each session. After getting this cookie informations, you should type the following command on the remote host.

% xauth add hostname:0 MIT-MAGIC-COOKIE-1 091fcf131a5c647869f2f4d5bf45e26c

After this, you can get X’s windows from remote hosts to your cygwin X.

Coordinating (official) trip to Hawai’i

I’m planning to go to hawai’i to do my univ work around 7/22 to 8/17.
And now, write many mails to staffs who are working at subaru/hawaii. I’ll try to upgrade our astrophysical instrument for next observation in this trip. Currently, we have some drawbacks to do observation perfectly. We can do of cource, but our instrument have to be upgraded for getting the best data..
Yeah,, you might say that barely one can observe with the perfect performance (not only the instruments,, but also seeing conditions, sky transmission efficiency, high clouds, etc.). But if you are a technician, i hope you’ll understand our challange..

And, I think my response around that period will be slow.. So please wait without haste.
