随机应变 ABCD: Always Be Coding and … : хороший
Let’s write it for testing
root/ ├ bin/ ├ etc/ ├ usr/ | └ local/ | └ bin/ └ lib/
In conclusion, as long as there are at least the following two symbols, it does not bother me to a certain extend when writing DFL.
├ └
Somehow, I want to write in markdown form for DFL.
text-align does not work well
#btright{
text-align:right;
}
change to margin auto
#btright{
display: block;
margin: 0 0 0 auto;
/* text-align:right;*/
}
mysql> create table news(
-> id int auto_increment PRIMARY KEY,
-> content varchar(10)
-> );
Query OK, 0 rows affected (0.25 sec)

If I enter an amount that exceeds data type, only the acceptable number of bytes will be in the record.
TINYTEXT
character type large object column, maximum length is 255(2^8 -1) characters.
TEXT
Character type large object column, maximum length is 65,535(2^16 – 1) characters.
MEDIUMTEXT
Character type large object column, maximum length is 16,777,215(2^24 – 1) characters.
LONGTEXT
Character large object column, maximum length is 4,294,967,295(2^32 – 1) characters.
Let’s get started.
mysql> create table news(
-> id int,
-> news mediumtext
-> );
Query OK, 0 rows affected (0.54 sec)
mysql> describe news;
+-------+------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+------------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| news | mediumtext | YES | | NULL | |
+-------+------------+------+-----+---------+-------+
2 rows in set (0.03 sec)
すげー、なるほど^^
The CodeDeploy agent for each instance polls CodeDeploy to decide what to retrieve from when specified Amazon S3 bucket or GitHub repository.
The CodeDeploy agent for each instance gets the target revision from the Amazon S3 bucket or GitHub repository and uses the appspec file procedure to deploy the content to the instance.
たった1人からはじめて、「越境」するチームをつくるまで
推薦されたので、読了した。
最初、「越境」という意味が、国境を超える、と思っていたのだが、そうではなくて、一歩踏み出す、という意味だ。
本書はソフトウェア開発における悩みやその解決のアプローチ方法を多数提示している。よって、環境や立場は異なるが、各登場人物の心境に共感できることが多く、読み物として楽しめる。俯瞰して読むことで、チーム開発においては、身勝手な行動は一切慎むべきだということが手に取るようにわかる。また、突き詰めると、エンジニアや当事者のスキルセット次第ということもよくわかる。スキルが足りないと、コミュニケーションミスが齟齬が起きやすいように感じた。

Set the log output destination in error_log of php.ini.
When describing the file name, write it with absolute path.
To display as HTML on the web, specify the log output level and turn on the log display setting.
display_errors = Off
To keep it in the file, set log_errors.

just write php.ini
