Question one:When the signal on the tamper pin changes from 0 to 1 or from 1 to 0 (depending on the tpal bit of the backup control register BKP_CR), an intrusion detection event is generated. The intrusion detection event clears all data backup register contents.However, in order to avoid loss of intrusion, the intrusion detection signal is the logic of the edge detection signal and the intrusion detection allow bit, which can also be detected before intrusion detection pins are allowed to occur
reading the books in the book, but those books tend to introduce the simplest and most traditional ways. This leads many people to use MySQL as a direct link to the database.
The favorite is to connect to the database through DBI, such as ActiveRecord and Propel ORM (object-relational mapping).
For example, take ActiveRecord as an example, if you want to implement such a SQL narration ...
Insert INTO ' users ' (ID, name, gender, location) values (1, ' Roga ', ' Male ', '
-relational Mapping), is very useful.such as ActiveRecord, if you want to use PHP now to operate such SQL statements:INSERT into ' users ' (ID, name, gender, location) VALUES (1, ' Roga ', ' Male ', ' TPE ')PDO notation:PHP $sql = "INSERT into ' users ' (ID, name, gender, location) VALUES (?,?,?,?)" ; $sth $dbh->prepare ($sql); $sth->execute (array(1, ' Roga ', ' Male ', ' TPE '?>The writing o
ActiveRecord as an example, if you want to implement such an SQL statement...
Insert into 'users' (id, name, gender, location) VALUES (1, 'roga ', 'male', 'tpe ')
Written as PDO:
The Code is as follows:
$ SQL = "INSERT INTO 'users' (id, name, gender, location) VALUES (?, ?, ?, ?) ";
$ Something = $ dbh-> prepare ($ SQL );
$ Something-> execute (array (1, 'roga ', 'male', 'tpe '));

Column function. In addition to the basic Prepare and Execute functions, PDO can also specify a single Column of Bind and a Column type.4. PDO is a physical action Layer. Therefore, it takes the least effort to replace the storage media.Unfortunately, render manager has been around for a long time, but it is still not popular enough. I think it may be because you are used to reading books from other places, but those books often only introduce the simplest and most traditional methods. As a res

In this way, the thread pool can dynamically adjust the number of threads in the pool.Step 2 (code) The code is as follows:Copy code Import java. util. concurrent.

If all three are full, handler is used to process the rejected task.When there are few tasks to process:When the number of threads in the thread pool is greater than corePoolSize, if the idle time of a thread exceeds keepAliveTime, the thread will be terminated. In this way, the thread pool can dynamically adjust the number of threads in the pool.
