Tomoko's Blog

Originally I made this blog to communicate with with my friends I made with in London . I arrived in London at 14th April 2005 and this is my start studying here. I like computer staff and would like to develop knowledge in that field . I am getting some knowledge from my friends who are so much in that field. So I would like to try what I get and put them on this blog which is useful and understandable for non computer expert person besides my personal diary.

Flight to Japan


I came to Heathrow again. There was no way I can run away.

Until the last time, I continued to express my unhappiness. However I got on the air plain.

I chatted with my next gentle man. He said he is French and a freelance clothes designer. A clothes designer sounds so impressive. He looked nice and friendly.

I thought I am lucky to have a good neighbor.

When flight attendances came to us to give drink, he said “German beer, please”. Our flight is Lufthansa and German company. I guess this is why they serve German beer.

I thought it is a good way to enjoy the flight to have something I do not really have daily life.

I said “Can I have German beer too, please”.

I drunk German beer with some small pretzels. I started to feel “not bad”.


What I have got in UK

There are lots of thing I have got in UK.

One of them is the ability to get information and analyze by myself. My ability might not enough strong to proud on my blog globally. However at least I know how we can make our individual opinion independently.

British and Japanese education are so different. In British education, writing essay is assumed one most the most important skill because this skill allows people to become individual thinkers. Because of this skill, people can use the knowledge they have to organize and structure their thought. For you, British people, it might be too obvious. However I did not know that.

In Japan, we pay much attention to the amount of knowledge.

Now I have some scary hypothesis. Japanese people are not meant to be individual thinkers. Japan has not natural resources and it is just a tiny island. If all people start to be individual thinkers, we can not work effectively because we start to discuss what is nicer and so on and stop our hands. Japanese government decided to make us effective tools which just have knowledge. They do not treat us as human?? To survive, this might be the only way for us.

I have more confidence in me than before. My thought is not depending on someone just myself. If I want to think of something, I can search the information and analyze by myself.

Especially now I have got a better command of English. This command of English gives me more chance to access to the huge amount of information source.


Something British?


I have seen something really British for me.

When I was walking near the Kentish town station, I find a young lady and black huge man arguing something. For me that black huge shouting man looked scary however the young lady did not look scared at all and shouted back to him. If I got shouted at especially in Japan, definitely I will be scared because people who shout seem lost their mind and they might do something violent. When I saw this young lady and huge man arguing, I realized that people are not supposed to do violence ever here even if they shout each other. Is is correct?


Isolation


My life in London was not good recently. What I suffered most is the isolation. Are you the person who can understand the pain of isolation?If you are a house wife, I think probably you can understand this. I remember, my mother said that after she married and moved to Tokyo with my father, she was not happy.

My mother is from a southern part of Japan, Kyushu. She was not familiar with Tokyo and it was really hard to make friends in that urban cities. I know many wives experienced isolation.

I need interaction with many people in my daily life. Without it, I start to feel anxious.

I made some precious friends in London and I am the person who decided to stay in London and LOVE London.

Sometimes I went to a pub by myself. At the pub there are many people who come with friends and looks happy. Something like three girls and boys. They might be old uni friends or colleagues. I wanted to be a part of it somehow. Maybe my stay is still too short to find many close people around me in London.

Beside the isolation,I am still working on my dissertation and just stayed in the room. I am reading huge amount of article and for me it is quite hard. Technical article sometimes required structured knowledge to understand however quite often I am lack of it. Every time I needed find out what knowledge I need to add and that required more article.

You might not believe I like studying and learning new things. It is really exciting.

/computer/ISO file

ISO file. I took me effort to understand what it is.
ISO file is the file with file system.
I would like to use the metaphor of sandwich.
Let's say. the bread is hard drive.
Butter or mustard is the file system. What we put on top is files such as ham or cheese or egg. Normally we are only allowed to copy file itself and we can not copy file system. We can move ham or cheese from one sandwich to another. However we can not move
butter or mustard, can we?!
ISO file is the copy of file system together with all the files on it. To make an ISO file from our CD or hard drive we need to use a utility like Alcohol 120% (see my blog /computer/alcohol120%) for Windows. It works as if it takes our butter from the bread together with everything what we put above the butter.

21. macosx alcohol 120%

This question is about Acohol 120% software for Windows which I discussed in my blog (/computer/alcohol). Since MacOSX is a UNIX file system, there are tools other than Alcohol 120% to make image files from CDs to copy them. To make ISO files from CDs etc we need a standard UNIX tool "dd" with a command like
"dd if=/dev/cdrom of=file.iso"
For further details on dd please refer to, for example, here:http://en.wikipedia.org/wiki/Dd_%28Unix%29

You can copy your ISO file wherever you would like to. After we made an ISO file (in our example) we can even directly work with it as if it was a real CD. The easiest way - again, there is a UNIX native utility - "mount". With mount command we can mount ISO image files and make them appear as if they were real CDs like that:
mount -o loop file.iso /mnt/myvirtualCD
and after that use it as a normal CD which you can access in /mnt/myvirtualCD. Of course, you need to create an empty directory /mnt/myvirtualCD in advance, before you mount anything to it. More details on mount tool you can find, for example, here:
http://bama.ua.edu/cgi-bin/man-cgi?00+00

So, dear MacOSX users, please try it out. The name of your operation system is UNIX.

For Linux (and other UNIX operation systems) with KDE desktop environment there is a very nice graphical tool "Acetone ISO" (http://digilander.libero.it/acetoneiso/). Very good looking and very powerful as well!

20. linux ext3 defragement free
I guess this visitor wanted to find a free tool to defragment Linux file system ext3.
We do not need fragmentation for Linux file system.
If you find your computer is slower than you expect under Linux, you had better search another reason of bad performance.
The users of Windows frequently meet such kind of problem that because of defragmentation of their file system.When I installed Linux for the first time, my first question, as an experienced Windows user was exactly like that - I considered it natural that we need defragmentation. I was wrong :)
By the way, Linux name of windows file system is either "ntfs" (for Windows XP by default) or "vfat" (Windows XP optional file system, which is also called FAT32). I already talked about it in my blog (/computer/defragmentation). Linux originally has better file systems - ext3, reiserfs and others, which do not have a problem of defragmentation.

like him. You can try.

18.japan+dentist + price
Japanese dentist pricing system, it is fixed for each treatment.
Regardless the quality of dentist, the price is fixed.
I have a friend who was a receptionist at the dentist. She told me a secret.
Do you have a experience your dentist explained again how to brush your teeth even though he/she explained last time. They are charging for this explanation.
We can never ask a detail receipt from dentist because they do not want make things clear.
Since we have the fixed pricing system, we should make pricing clear.
After I heard this story from my friend, I always feel bad when my dentist explains
how to brush. Of course every time I try to prevent him.
I hope some brave person someday ask him not to do this.
19.japanese phrases for wedding parties
I think you can just say "congratulation". In Japanese you can say "omedetou gozaimasu".

movie

I was shocked to hear that one of my friends have never gone to restaurants before he came to London. He said he has seen people go to restaurants on movie and he knows
how he should behaves. I guess he was so nervous when he went to restaurant with his

Do you have something you have never done but you have seen on movie and lean how to
do for?
I was thinking today that if I have something which I have never done but I have seen on the movies.

/computer/ fileownership3


How to define a group for the file ownership.
I am taling on the KDE interface.
"system"
"use manager"
We shall open the window of "use manager".

/computer/linux file system 2


We already know that one of th main advantages of Linux file system is the ability to regulate ownership of each directory and each file. The permissions system is, at the same time, very flexible. Today we shall see why.
For a file apart from its user owner there is also a group owner.In other words, each file is owned by one user and one or more groups of users. Any users can be organized in groups. Each group can have its own name. Groups and group names are defined by the superuser - the root.We shall see how to define a group later.
User owner and group owner may be unrelated. For example, a file is owned by user "tomoko" and group "students", but, at the same time, "tomoko" not necessary needs to be a member of group "students" to own a file. Note that a user not necessary needs to be a part of any group. Same way, a user also can belong to several groups simultaneously. Usage of groups allows a very convenient way of permission control. For example, if I want some files to be available to several people I just need to create a new group and add them to the group. After that I can make this group own the files I want.
For each file and directory there are three basic ways how a user can access them: read, write and execute. Directories are also kind of files.

/comouter/linux operationsystem/filesystem 1


Linux operation system is different from windows operation systems
Firstly, we've got to know one name "root".
"root" is the standard ID of the user who rules Linux operation system on a particular machine. Normally, system administrators are "root". Root user has unlimited permissions to modify Linux.
"root" is more than a name. I will explain why.
The file system of Linux resembles a tree. "root" is really the root of this tree. The access rights of users to the file system is very organized. A user is like a branch on the tree. This branch is represented by a directory (folder, in Windows terms) of which he is the owner. We can easily imagine how directories form subdirectories. It resembles branching of branches very much. At the tips of the branches there are leaves - the data files. Each user has full control on his directory and all its subdirectories. Thus the users located close to the root of the file system have more rights than the users located at the distant branches. Root is located below the whole tree. That is why root has unlimited rights.
Of course, unlimited rights mean huge responsibility. Limited rights mean relatively small responsibility.
Linux file system has a set of standard directories which come from root:
bin, etc, usr, home, mnt, dev, lib, tmp, var, lost+found.
In home directory we can find subdirectories for all human users of the system. For example, if I am registered in my Linux system as "tomoko", i will be given my subdirectory in /home directory: /home/tomoko. In my directory I can do whatever I want, but I can not read or modify directories /bin, /etc, /dev,... and so on. I can not even modify the directory /home, because it is closer to the root than /home/tomoko. From the letter idea we can conclude that I (tomoko) can not create new directories in /home which can be used for new users of the system. Other users (same as me) will also have no access to my directory (where I might store personal data) unless I will give them links to the files (or directories) which I want to share with them.
Only root can modify the directories at /home and upper. It means that only root can create and delete new users, install and uninstall software, modify settings of Linux. That is why Linux is VERY SECURE.


Secondly we've got to know the idea of "inode".This is like a straw in the cup.
We can access to the file though the inode and read or write the files.

/computer/linux sabayon installation 3


This is the third article about the installation of the Sabayon Linux.
we are to setting the "Boot Loader Configuration".

After we successful set the "Boot Loader Configuration", we are supposed to have
the booting screen like the third slid of my picture.
As you can see, we can choose, either Sabayon or Windows.

1. we are to choose partitions and set as boot loader.
I choose "/dev/sda1" and name it as "Windows xp".
I choose "/dev/sda5" and name it as "Sabayon Linux x86 3.2". Of course, you can name
them as you like.
2. If you want to "Windows xp" automatically configuration operation system, you
can tick the box of "Windows xp".
If you want to "Sabayon Linux x86 3.2" automatically configuration operation
system, you can tick the box of "Sabayon Linux x86 3.2".
