The noun of “Outlet” and the verb of “Action” like reading book for computer language

As for Swift language which controls iPhone APP, there is interesting definition: “Outlet” and “Action”.

For those who are not so familiar with Swift or computer language, please see “Outlet” like noun and “Action” like verb from language definition.

One of the key roles about noun is it can be subject in sentence. In this respect, “Outlet” works like subject on program while its meaning can be more detailed with its property, or what I would see as if adjective. Why “Outlet” looks noun is it always connect to object. It appears the name of object.

On the other hand, “Action” do something as its name suggests. Mathematically, “Action” is like function itself. It deals with the input and show the output on its rule. In some cases, the input may not exist, which is different from mathematical function. But, it always has the output so it always do something whenever it is called. Technically, we can control the timing of when “Action” should be called as verb has the rule of tense.

To image things above easily, let’s see a switch of some light. If you switch on some light, the blub lights up your room clearly. This kind of incident can be seen on iPhone APP in a lot of views. In this case, the switch can be “Outlet” and “Action” is lighting up.

As you know, there are many types of switch in the world; size, color or shape. This kind of features can be the property of switch. So, you can choose the design of switch as “Outlet”. Next, you can create “Action” as if you can decorate how the bulb lights up your room. How many light bulbs you need? Yellow or Blue light fits your room? Do you like heavy power battery type? This kinds of desire could be shown as your “Action”.

If you get familiar with these “Outlet” and “Action”, you can see the script of programing as if you read some story on a book.

The first step may be difficult but this could be interesting.

Position of Japanese verb

As I create language training iPhone APP , I sometimes realize the difference between Japanese and foreign language. One of the most unique features in Japanese is that verb has to be located at the last part of sentence. In addition, negative word such as “not” is integrated in Japanese verb so we cannot determine which sentence is affirmative or negative until we listen to the full sentence. This language feature sometimes reflects the personality of Japanese people. We tend to show important and precious things at the end. So, we easily add our intention and let others to keep it after the conversation conversation is finished. The later you hear, the newer things you hold. So, you will not forget as the last one as first. However, it has also some bad aspect. We Japanese can easily change the point of what we say while talking. The important point can be intentionally hidden if necessary while checking the reaction of listener because we can say anything before reachin

The value of expression | learn speaking

People decide the personality of the man whom they meet at first mostly by his expression. 70% of first impression is determined in a few minutes after they meet. So, facial expression is worth a thousand words. Please remember it especially for your job interview. Nevertheless, Japanese people are not good at expressing. They rarely use body language as well. This may be related to the background of historical culture. Too much expressions are sometimes thought to be rude in the soul of samurai especially for men. They always had to stay cool in any situation. And, to reduce the inefficient movement, their fighting skill could also be improved. On the other hand for Japanese women, they tended to think to stay modest was quality of beauty or noble. They had to follow their husband for anything. This kind of thinking continued until the end of world war two since that foreign culture had installed into Japan so much. After that time, samurai or modest women spirit apparently d

Draft note with voice writing

Draft note with voice writing If you have some smart phone like iPhone, you may find it has voice writing tool. Have you ever tried to use it? It was thought to be difficult to use at least several years ago and I actually thought so. I remember the first time the app of voice writing was released on iPhone APP store. It was about 10 years ago at the version of iPhone 3G. I am kind of gadget mania so I was very excited about it. Even though it was so exciting, I found it just a play tool and did not continue to use it as a daily utility. Typing was much easier than it. After Apple officially attach the function into keyboard, I never used it until now. The first experience which remind me of the difficulty for writing prevented me from using it. But after the long time, came the chance for me to use the tool again. I forgot to bring my PC on business trip while I wanted to create some document. It was a kind of hard work to write on iPad without keyboard.  So, I came u
