An engineer's life around Kyoto

Although I am not an Asterisk user, I encountered the information that the recent security update of Asterisk contains  a backward incompatible change.

Recently, when I launched powertop in my "squeeze" machine,  it crashed. Hmm... I looked around the Debian bug database and finally found the cause. The bug report #646522 says that it crashes if /boot/config-* has more than 5000 lines. Yes, I ran the kernel of linux-image-2.6.32-5-xen-686 and the package contains a config file with 5023 lines. That's it!

A few weeks ago, I upgraded one of my Debian box from squeeze to wheezy. Upgrading task was not so difficult, also I had to manage a trouble concerned with X11. Then I tried running Xen dom0 kernel upon the Xen hypervisor 4.1. After the installation I booted the hypervisor followed by the dom0 kernel. When a X server launched, the screen was filled with the textile-like tiling patterns. But after several seconds, the normal GDM login console appeared. I did some tasks in the desktop environment, for example, watching a video stream. During the tasks, I encountered one Xserver's crash and one kernel panic. The thing around Xen and xorg's Intel driver must be getting better. But it seems to be still unstable.

The planned electricity outage for a peak overload has never taken place this summer in Japan. Although we were encouraged to cut ten percent peak load off and avoided the outage, we might lose a chance to learn enough how much we depend on uninterrupted electricity supply in the western part of Japan, which the huge earthquake didn't hit directly last year. It is still in question on the papers whether the two atomic power plants, which were re-started in July,  were necessary.
