Maitta! Always - Daily Amazing Confusions -

I'm studying about Linux server applications for LPIC 202 exam. I hope I'm going to take the test by the beginning or the middle of June. Because I plan to the 202 exam earlier than 201, I will have to study for and pass the 201 exam also, to take LPIC Level 2 certificate, even after I pass the 202 test. These days, I have come to know that I haven't fully understood a few important network services which support cyberspace today. For example: When I learn about Domain Name System, I haven't fully understood basic concept of this protocol. I'm confusing the difference of subdomain and host name. It looks like they don't make difference as far as the system's syntax is concerning, but a subdomain stands for a particular host when domain name database has an entry for it. Public keys, frequently used in secure network connections, has two roles, encryption and digital signature. I'm easily confuse one from the other, which make me hard to really unde...

When I woke up this morning, I had completed the entry for yesterday. Before supper, I wrote the core idea of my draft, but I was not sure that I had completed my composition. Actually my entry may be incomplete as composition, but I was relieved that the entry for "not all my characters are proficient" has status of "posted". By the way, although I don't think that I have multiple personality disorder, sometimes I feel alternating my personalities between capable one and incapable one. This is the reason why I came up with the title of the entry of yesterday.

Not all of my characters are proficient. Sometimes I feel, I'm totally foolish, as if my personality totally changed. Actually sometimes I understand many things, and sometimes I make a lot of action, but sometimes my faculty of understanding is almost sleeping, as well as I get quite inactive.

In order to understand more, I sometimes to type RFC documents. These days, I'm typing ones about SMTP and TCP. While typing them, I noticed that there are two spaces between periods and the beginnings of the next sentences, in plain text version of those documents. I looked up punctuations on the internet and according to search results, it looks like it's not good to put two spaces after a period with which a sentence ends and begin the next sentence. I imitate as I see anyway, when I'm typing, but when writing a document by myself, it looks like I have to decide I take up which style, one space or two, between sentences.

I walked like a penguin, with my sore legs, tired with the half marathon yesterday. It' going to take a few more days before I begin to walk like myself regularly.

Today is the day of Sendai International Half Marathon. Finally I made it, but it was the toughest run ever. After 16 kilometers, my stamina almost ran out, especially in my legs, and almost stopped running. I didn't actually stop running, but I went as slow as I regularly walk. I had thought that I had built enough stamina, by cycling and swimming, but I was finally taught a lesson that the amount (distance) I actually run before the day of the race is also important. The maximum distance I had jogged one time since I registered for this year's event.

I'm thinking of getting PlayStation 4. I have PlayStation 3 and played 3 works of Arland series. In order to play recent Atelier Series, it's likely I need PlayStation 4. Considering budget, whether I'm really getting one is uncertain, and it will be one or two years later if I'm going to get.
