Maitta! Always - Daily Amazing Confusions -

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.
