Our second daughter was born

Dec. 2nd, 2010 | 05:42 am

A little bit late but ...

Our second daughter, Asuka, was born on 2010.11.29, 14:11. She was 3055g at birth and looks a lot like her elder sister, Karen. My wife and she are both OK and I can't wait that they leaves the hospital and come home.

The article about packaged vm is out: Software Design 2010年6月号 but miniascape is not in usable state yet and I keep hacking on it.

it seems that they did not contribute to btrfs

May. 16th, 2010 | 11:04 pm

I read the article Btrfs Possibly Default File System Next Ubuntu Release and dreamed up to check out what they did for btrfs just from curiosity:

ssato@localhost% git log --diff-filter=AM fs/btrfs/* > /tmp/btrfs.log                                        ~/repos/public/kernel.org/torvalds/linux-2.6.git
ssato@localhost% sed -n 's,Author: \(.*@.*\)>,\1,p' /tmp/btrfs.log | sort | uniq > /tmp/btrfs.developers
ssato@localhost% grep -i canonical /tmp/btrfs.developers | wc -l                                             ~/repos/public/kernel.org/torvalds/linux-2.6.git

ssato@localhost% grep -i oracle /tmp/btrfs.developers | wc -l                                                ~/repos/public/kernel.org/torvalds/linux-2.6.git

ssato@localhost% grep -i suse /tmp/btrfs.developers | wc -l                                                  ~/repos/public/kernel.org/torvalds/linux-2.6.git
5
ssato@localhost% grep -i ibm /tmp/btrfs.developers | wc -l                                                   ~/repos/public/kernel.org/torvalds/linux-2.6.git

ssato@localhost% grep -i fujitsu /tmp/btrfs.developers | wc -l                                               ~/repos/public/kernel.org/torvalds/linux-2.6.git
7
ssato@localhost% grep -i redhat /tmp/btrfs.developers | wc -l                                                ~/repos/public/kernel.org/torvalds/linux-2.6.git

This is pretty simple survey and should not reflect their development activity precisely, however it seems there are no developers from canonical contributed to btrfs.

I recalled the famous presentation: Linux Plumbers Conference 2008 Keynote. I strongly hope this situation was changed since then.

Relocated from Nerima-ku (Tokyo) to Yokohama city

Mar. 8th, 2010 | 11:34 pm

We sold old condo we lived in and bought a new one, and relocated from Nerima-ku in Tokyo to Totsuka-ku in Yokohama city.

One of the reason we moved is that we think Yokohama is better place for raising children. There are many playgrounds our daughter likes, for example.

Our new condominium building is bigger than previous one and is surrounded by greenery. We have a line of cherry blossom trees along the path to the entrance and I'm looking forward to walk under the trees in full bloom during travel to or from work weekday.

Extract package metadata from RPM file[s]

Feb. 23rd, 2010 | 06:19 am

It must be useful if there is a tool can export package metadata from RPM files, I guess. So that I wrote a couple of scripts doing this in different styles:

  • rpm2json.py extracts metadata from RPM files and output these as JSON data. you can specify which rpm tag values are dumped. also you can see all possible rpm tags list with its --show-tags option.
  • rpms2sqldb.py creates SQLite database from RPM files. It will generate multiple database files for each RHEL versions guessed from RPM files.

Requirements: both needs rpm-python. Add to this, the former needs python-simplejson and the later needs python-sqlite3 which included in python itself since 2.5.

Two inconsistent parts of Intel

Oct. 30th, 2009 | 12:15 am

Blaming Intel for how the world is via mjg59: More GMA500. If its (the author of the article at moblinzone.com) logic is consistent and what Intel is doing is right, mobilin (which lacks of psb stuff) looks a kind of joke for me.
