Maitta! Always - Daily Amazing Confusions -

Swimming in the breaststroke, I want to open my arms wide, just because it is the most efficient way to get my shoulder advanced, and center of gravity. When I was young, I had imitated how wide the arms were open, but I haven't understood why, that is the purpose of its arm stroke.

My focus of this month, September 2020, here was the number of posts, whatever the quality of each post might be. This month has already passed more than half way through, and I issued only 11 posts against what I had planed 50 posts. From this perspective I haven't done very well for my focus for this month. To improve this situation, I don't want to keep to myself what I felt and learned in my everyday life.

The problem was I didn't want to be found. I was advised, "If you want to success with SEO (Search Engine Optimization), you want to focus on 'How do you want to be searched and found on the web'". When I opened this blog, I didn't really want it to be found, although it was a bit discouraging to find that no visitor came in the first month. Now, 11 years after I opened this blog, I have a few visitors here in a week. Now it may be time to take it seriously that how my contents want to be found - with what keywords - and how to welcome visitors.

Shutdown at the entrance of my local church, at 10:35 a.m. Sunday service starts at 10:30 a.m. I had limped before I reach near the church. I shouted out loud and collapsed at the entrance of the church when a worship song started. I felt the sound as if electricity had run through my body. It took 5 minutes to stand again, when a kid ran to me, concerning about myself. I recalled my language and told him that I was O.K. I told him that I fell just because the sound struck me out. Certainly I was down in this Sunday morning, and too down to walk straight. The sound is too loud. Is it because of high humidity of today's weather? Yesterday it poured all the day long around Sendai. I changed my schedule on Saturday, and went to a local indoor pool around noon right after I visited a mental clinic. Usually, on Saturday and Sunday, I go to the pool at 3 p.m and swim for one and a half hour. I changed my schedule on Saturday because it was expected, according to weather forecasts, to rai...

Write something. I say to myself when open the blog console, but I have no idea to write. When I come up with a "wonderful idea", I'm not ready for noting it and forget it with time passing by.

I have been learning  The C Programming Language by Kernighan and Ritchie since this May. I studied C, the programming language at numerical calculation class of university and have already know basic syntax of it and how to compile. However, I know little about how the language have deeper access to particular hardware architecture. Neither had I known more than a little about how it was used to program UNIX and UNIX-like operation systems such as Linux. Just recently, I have had a desire to know deeply about how Linux and other UNIX-like os which can run on the hardware I have, and learning deeply about the language from the basic is the essential part to achieve this. Reading the first tens of pages, I thought that I had already known most of things written on these pages. However I realized that I haven't been familiar enough with it. Advancing to next pages anyway can be a good idea, but finally I decided, "Why don't I try inputting the sample codes, compiling them, ...

It often happens to me that I don't come up with anything to write. No surprise. I often doesn't come up with what to say when I'm asked to introduce myself. It happened so many times that all I could do was stand still, blushing, frozen and stutter when I was asked for some comment. It even happened when all I had to do was saying my name. Of course, I don't think I really forgot my name, but at least I couldn't say it. This shows that the reason I can't say anything isn't always I don't know the perfectly right words.  In this case, I even know the exact word - my name. (Perhaps I may be embracing the desire that I would have been anyone else. Anyway, when I can't say my name, I often don't like myself very much.) As well as I sometimes have try hard to say my name, I often have to make extra effort to say what I'm in mind. Knowing right words might help lot, but it can be a double-edged sword. Although it may be definitely necessary to kno...

You have perhaps already gotten through more than half the way out of suffering, if you are able to explain well enough about you and any disability. What the disability has to do with you. I have been thinking this way after the vain attempt to explain who I am, how I have been suffered, and what I have had to do with autism spectrum disorder. It was 27 years ago I knew about high function autism through a book by Donna Williams. The doctor I met with after I became mentally wreck referred to the book to describe difficulties in my daily life. A teacher and parents took me the mental hospital after I got almost unable to understand the natural course students are supposed to do at high school, and absent from it for a few days. I even forgot if I had eaten breakfast or lunch in the morning at that time. It was soon after then that many books from authors with high function autism or Asperger's syndrome were bestseller. I was thinking that I would be successful as one of followers ...

Recently I have been writing documents with which I teach fellow engineers a certain network technology. I use the assistance of PowerPoint slideshow. Still, I need the script to give a smooth lecture. When I improve the script, I make it a rule to read it out loud, record it, and listen it back. If there are some unnatural expressions, I usually notice when recording, without waiting for completing the recording and listening back. With this great power of improvement of recording my own speech, I'm beginning to think "Why don't I take advantage of this in order to enhance my blog contents."

In my childhood, I was always drawing pictures of automobiles. Even after I go to elementary school, my notebooks and even textbooks were full of pictures of cars. I sometimes draw people and some character of comics, but automobiles were more than 10 times of such drawings. With severer exhaust gas emission regulation in the late 1970s and early 1980s, up-to-date cars then became less powerful than early 1970s. Since I was always viewing data books of automobiles, this decline of engine power disappointed me a lot, even though I was too young to feel the change of power by driving them by myself. Still exteriors of brand-new cars were all the same attractive. At that time, I preferred Nissan to Toyota, because the former had cars I liked very much; Nissan Skyline [Wikipedia] , Bluebird [Wikipedia] , and so on. Even after I came of age, it took really long time before some cars are available for me with my earning and saving. Once I saved money to buy a car, almost all my hero cars has...

I don't always remember my strong point. Actually, it's especially easy for me to forget my strong point when I have free time to write for myself. Instead, I tend to remember my negative sides, pessimistic thoughts. The reason for this is probably because I'm not able to describe with my own words. Even when I have relatively clear ideas with which I'm assertive, because I don't know the right word for me to describe. Finally I totally give up communicating. With the fact that I don't know the right word for describe myself, it's time to face up with the fact of the lack of vocabulary. It's not enough at all to get full mark of a particular language test, to get full mark in the test of describe myself fully. In order to overcome this, I'm thinking of reading books more frequently, taking advantage of free copies of classics available in Kindle.

Just after I set up the OS of my Raspberry Pi 4, I tried to connect to it via SSH from my PC. I generated and installed keys via scp with the PuTTY suite. PuTTYgen and pscp. Recently OpenSSH on Windows 10 has already been available, so why didn't I use this? One reason, unfortunately, is language mismatch. First I just tried the ssh command on the PowerShell of my Windows 10 PC just as I would do on a Linux host with OpenSSH. Voila! Looks like a ssh client has already been ready for work. I accepted the host key and connected. Some output didn't display properly. I looked up for problem and it's because of Japanese encoding mismatch from the initial setting of my Windows 10 PC. Fortunately, with PuTTY, everything, including Japanese displayed properly, so I decided to set up for PuTTY first. I learned that the format of key pairs varies from SSH server and client, for example the default name of RSA secret key for OpenSSH is "id_rsa" and one for PuTTY is "id_...

It was not until Sunday that I began assembly and setup of my Raspberry Pi 4, although it had already arrived on Friday. I start assembling the heat sinks, the fan, and the case.  I connected to the monitor of my main desktop PC with the HDMI cable, but not having really known how to change input for the monitor, when I powered on the Pi with the install media inserted, I couldn't see any graphic from it. I connected to my TV, changed cable and waited for a while. I confirmed both ends of the connector connected firmly. With a few trial-and-errors its graphic finally showed up. I installed Raspbian, the default OS, with the guide of installer. I set the language of system Japanese, but I haven't installed Japanese input method. Well, it's of lower priority. My priority is setting up SSH, connecting from my PC and setting up public key authentication, then setting up a web server, perhaps trying docker and its containers. Next, I'm setting up SSH on my Pi.
