I had no time for something due to working. I wrote many documents, technical article, specification. Mainly It's all about Linux. Moblin, Chrome OS, How to up performance on Desktop Linux, and Recovering the vintage PC as the Linux box and so on. But I don't feel that better writer more than before :-) You know writing documents is difficult.
2nd. I could meet many people. Especially It was in San Francisco. I attended Linux Foundation Collaboration Summit :-) This is my memory of the best of all!
I think I will be busy next year. Anyway I have to more study English. Currently My dream is working in oversea!
Anyway Have a good new year!!!

This is the login sequence of Chromium OS.
- Graphical login. slim is graphical login manager for chromium os.
- Input your google account.
- pam_google.so. If you don't save login cache of your google account, It has to connect network. pam_google.so is Google account authentication PAM module.
- pam_mount.so. mount to /home/chronos as tmpfs. so If you power down the system, user data will be removed all. "chronos" is a default user of Chromium OS. This mount is encrypted AES and SHA256 hash algolism.
- run chromeos-wm. It's Clutter based window manager.
- run chrome browser.

I thought that will buy CECH-2000A is the latest PS3. But CECH-2000A can not install another operating systems. Isn't it joke? It's true. If CECH-2000A, we can not try to run Linux!

Moblin 2.1: 2.6.31(-netbook, -ivi, -menlow, -mrst)
Chrome OS : 2.6.31(-chromeos-intel-menlow) but It isn't included psb driver
Currently, I think this kernel is for netbooks, CULV laptops
Moblin 2.1: Original
Chrome OS : Ubuntu Karmic
Moblin 2.1: vga=current quiet root=/dev/sdx (no initrd)
Chrome OS : (USB) quiet console=tty2 initrd=initrd.img init/sbin/init boot-local rootwait root=LABEL=C-ROOT ro noresume noswap i915.modeset=1 loglevel=1
(HDD) quiet console=tty2 init/sbin/init boot-local rootwait root=/dev/sda ro noresume noswap i915.modeset=1 loglevel=1
Both of them uses ply-image for boot splash.
Moblin 2.1: GRUB1
Chrome OS : extlinux
Mobln 2.1: ~10sec
Chrome OS: ~5, 6sec? Anyway USB boot is faster than Moblin. this was as fast as HDD boot. And Boot Booster for EeePC is enabled by second partition of EFI.
Device Boot Start End Blocks Id System
/dev/sdb1 1 618 4962143+ 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sdb2 618 739 972800 ef EFI (FAT-12/16/32)
Partition 2 does not end on cylinder boundary.
/dev/sdb3 * 739 860 972800 83 Linux
Partition 3 does not end on cylinder boundary.
/dev/sdb4 860 982 972800 83 Linux
Partition 4 does not end on cylinder boundary.
Moblin 2.1: connman 0.45, clutter 1.0.8
Chrome OS : connman 0.42, clutter 0.9
Maybe there are Chrome OS packages in the following.
chronos@localhost:~$ dpkg -l | grep chrome
ii chromeos-acpi 0.1 chromeos acpi scripts
ii chromeos-assets 0.3 Chrome OS platform assets
ii chromeos-chrome 0.1 chromeos chrome

ii xscreensaver 5.0.8-chromeos2 Screen locker for Chrome OS
ii xserver-xorg-video-openchrome 1:0.2.903+svn758-0ubuntu1 X.Org X server -- VIA display driver
Moblin 2.1: moblin-installer(anaconda)
Chrome OS : chromeos-installer(installation script)
this script deletes all partition. so It's no flexibility.
Chrome OS is splitted 3 partitions. one is data cache partition, two is EFI partition for Boot Booster. three is rootfs parition. /home to tmpfs to mount as. I think that is for appliance more than Moblin. As you know, Moblin is supported Atom processor based Netbooks, Entry-level PCs, MIDs, and In-Vehicle Infortainments. Long time ago, I suggested moblin should define security. e.g SELinux, AppArmor and son. But currently, Moblin is no defined. I think It's no good. :-(

I could become to speak and write English a litle. But It's hard for me yet.
As you know, Most Japanese can't speak English. Because there was a problem in educational policy. For example, We study to pass the exam to enter university and high schools.
And I don't like English long time ago. But I have to do for my dream.

Recently I have motivation and can write little English. Why did I post in English? I'll talk next time.
