The stronger a person is, the longer the person can graze at another person.

My CD player is almost broken. I will have to replace it in the near future without a doubt. But I'm in relative distress..., because of the world financial meltdown!

Full Blossom

It must be the most beautiful day of Tokyo in this year.



According to the weather forecast, it will be rain day after tomorrow and Someiyoshino cherry blossom will begin to fall.

MS Word day

I was badly forced to do paperworks today. Man often mistakenly feels to achieve a hard work even if he has merely done the paperwork. Will those papers I wrote today really be fertile?

Reason of books

I spent the afternoon with Chaitin's 'Meta Math!.' Though I'm still in reading, it's so excited that I want to say something. Something about books in general again. What is the advantage of 'Meta Math!' being the form of books? I don't know the precise answer. But I feel that it at least isn't because of the fact that it was published from a publisher.

I'm realizing that writing memo is fun by itself.

I can do nothing without her help. But it seems that she can do anything, at least her own jobs, without my help.

I can think of a dozen thing that I have to do than working with the current task. But it's not a good thought. I ought to achieve some fruits from any work, at least in principle.

I think the most annoying symptom of the hey fever is drowsiness.

It said to be hard for a baby under two months to walk around almost two hours. But the baby was in a good mood today after a short trip to Kitasenju. We are planning to go to Ueno next weekend.

My friends came all the way to see our baby.

My hobby

Learning and studying are my hobbies. None of your buisiness. I think there's nothing more exciting than these activities.

I need someone who can draw adorable technical illusts .

After three times rewiting, I just finished writing a tax preparation.

Baby on the belly

I inadvertently took a nap under the baby.

Gauche Night 2008 in Tokyo

I made a presentation of my life with Scheme at an event called Gauche.Night 2008. I haven't had a presentation for long years. But today, I think I overcame the difficulty, with a certain degree of beer and, of course, with support from everyone. Thank you so much for giving a chance to speak.

Reading a book

I recentry became to think that the good books aren't the medium through which we just get information easier or learn some new knowledge. Rather, good books ought to give reader restricted information dpending on the reader's comprehension of the time. In other words, same books are able to be read by a reader at several ages or a variety of stages of one's life. I can hardly imagine other medium having such ability. I'd like to think more about this characteristic of books if I'm working in the publishing.

Cloth diapers is not so economical if you use a liner. Rather it's ecological. But I'm not ecologist. It's nice because the odor smell does not remain with dirty diapers.

Passed away

There were piranhas in the waiting room of the dentist. But today the aquarium was empty. They all passed away. The staff girl said that the broken heater claimed their lives. I am a bit of pitty as they had always made me happy. May they rest in peace.

I'm reimplementing an in-house script from scratch because the licence of the script is not able to be open. Although I wrote the original one in my own leisure time, recent version is more contributed by my office hour. Thus, I know the company owns that.

Anyway the original ideas have been laid down in my head. And my understandings of Scheme has grown from when I wrote the original one. Here's the outcome of this weekend, which was achieved cradling the baby.

cnvr.scm
latex.scm

You can use these modules with Gauche to define some rules to convert SXML data to LaTeX, or you like, as below.

(use cnvr)
(use latex)
(use sxml.sxpath)
(use sxml.tools)
(use text.tree)

(define-simple-rules make-latex-cmd
  bold item)

(define-simple-rules make-latex-env
  li)

(define-simple-rules through
  p top body)

(define-tag a
  (define-rule
    (lambda () '())
    (lambda (str) 
      (list str "<" ($@ 'val) ">\n"))
    (lambda () '())))

(define sxml 
  '(top 
     (body (p "first sentence\n" 
              (a (@ (val "20")) "the attr: "))
           (bold "emph this!")
           (li (item "first line")
               (item "second line")))))

(write-tree (cnvr sxml sxml))

The result is this:

first sentence
the attr: <20>
\bold{emph this!}
\begin{li}%
\item{first line}\item{second line}
\end{li}%

It has still a big problem with macro. Of course the problem is variable capturing. If you define a rule with certain name like "list", it overide the procedure "list". But I decided to expose it in as-is.

Remorse

I skipped writing for several days. It's still hard for me to think in English having the other things to do. Practice is habit. But being with a baby keeps adults away from their old habits.

Even a sentence is enough.
