1. Remove duplicate elements from an array:
Using the GREP function code fragment:Code:
Copy Code code as follows:
My @array = (' A ', ' B ', ' C ', ' a ', ' d ', 1, 2, 5, 1, 5);
My%count;
My @uniq_times = grep {+ + $count {$_}
Using the Transform hash code fragment:Code:
Copy Code code as follows:
My @array = (' A ', ' B ', ' C ', ' a ', ' d ', 1, 2, 5, 1, 5);
My%saw;
@saw {@array} = ();
My @uniq_array = sort keys%saw;

The Microsoft Build 2016 Developer Conference was opened at the moskon Exhibition Center in San Francisco. This Conference has improved some key functions.

obtain a rainbow table (about the operating system or application) and search for the hash value to obtain the password stored in the user. Unfortunately, as the scale of the rainbow table continues to grow, the password must become longer and more complex, so that others can get the user's hash value. The ongoing work of assembling rainbow table data may soon make it meaningless to discuss the best practices for minimum password length, this is also the main reason why many experts believe tha

Overview
Smart locks refer to locks that are more intelligent than traditional mechanical locks in terms of user identification, security, and management. It is the execution part of the locks in the smart access control system. Currently, common smart locks in applications can be classified by user identification technology:

If the Linux system is pre-installed, then the market performance may not be too optimistic, because most users even buy this so-called Linux version of the notebook, you have to go back to install WIN7/WIN8.1/WIN10, of course, do not rule out someone will continue to install pirated XP. Rather than let the user own trouble, as millet themselves to the user installed Win10 to worry.

The security of Oracle databases includes the mechanism for controlling database access and use at the object level, which is implemented by database users. The database user is defined in the database
A name that accesses the information in the database and is the basic access mechanism for the Oracle database.
To access the database, the user must make a valid database user account and verify it according to the requirements of the account. E
The basic principle and process of fingerprint identification technology
Although fingerprint identification technology has entered the civil field, but its working principle is still relatively complex. Unlike manual processing, biometrics companies do not store fingerprint images directly. Over the years, the biometric companies and their research institutions have studied many fingerprint identification algorithms (the United States law that the

Windows 7 extends BitLocker disk encryption support to removable storage devices, such as flash memory and portable hard disks. This means that the user can store the sensitive data in a USB storage device.

"Your smartphone will track you all day and learn, plan and solve problems for you," said Angie Wang, a Gartner research analyst. It will use its sensors, cameras and data to accomplish these tasks automatically. For example, in a networked home, when you leave, the AI will clean up with a vacuum cleaner, or start the rice cooker 20 minutes before your arrival. ”
