My synthesis in 2009

This is my synthesis in 2009.

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!!!

Chromium OS(Chrome OS) login sequence

Image
As you know, I'm writing an article about Chromium OS(Chrome OS) and created some material. so I posted a part of memo.

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.

Ordered a PS3 (CECHA00)

Image
I ordered PS3 CECHA00 on Amazon. CECHA00 is 1st generation of PS3 and can only run the PS2 games. I was determining before I don't buy one until releasing FINAL FANTASY XIII(FF13). You know, FF XIII will be released 17th Dec.
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 vs Chrome OS

I compared Moblin 2.1 and Chrome OS before time.Project page
Moblin 2.1: http://moblin.org
Chrome OS : http://www.chromium.org/chromium-osKernel
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 laptopsBase distribution
Moblin 2.1: Original
Chrome OS : Ubuntu KarmicKernel parametor
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.Boot loader
Moblin 2.1: GRUB1
Chrome OS : extlinuxFast boot
Mobln 2.1: ~10sec
Chrome OS: ~5, 6sec? Anyway USB boot is faster than Moblin. this was as fast as HDD boot. An…

Why did I post in English?

Someone said "If you don't write blog in English, you're not the same as present. you did interesting something in Japan, But It will be checked only Japanese."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.

Why did I stop my blog during about a year?

Actually, Nothing special :) But It had an accident on last posting day after next day. Self hosting server was crashed! So I could not do during stopping server. After that, I recovered server, But I had no motivation that time. Also I was working very hard. And I didn't have margin of mind.Recently I have motivation and can write little English. Why did I post in English? I'll talk next time.
