The DES (data encryption Standard) algorithm, which was formally licensed by the United States Government in 1977, is a method of encrypting 64-bit data with a 56-bit key. Des algorithms are applied to many situations where security encryption is required. (for example, the UNIX cipher algorithm is based on the DES algorithm). Here is a description of how to implement the DES algorithm language, if you want its source code, you can go to the http//assassin.yeah.net download, the latter you have any questions can also write to me (as ...)

"What to think" and "what to eat" the two factions have been in the field of artificial intelligence two classes, two lines of struggle, this struggle is sometimes a life-and-death. Set a vulgar philosophical word, the former partial idealism, the latter biased materialism. Computer field now the most popular word is "depth learning" linguist Steve Pink the theory of neural networks to challenge Turing test to open the field of artificial intelligence in the battle of two routes in the field of artificial intelligence large Neumaichel _ Abib, founded the University of Massachusetts computer department. Since Turing proposed ...

This article describes ways to perform large data analysis using the R language and similar tools, and to extend large data services in the cloud. In this paper, a kind of digital photo management which is a simple and large data service is analyzed in detail, and the key elements of searching, analyzing and machine learning are applied to the unstructured data. This article focuses on applications that use large data, explains the basic concepts behind large data analysis, and how to combine these concepts with business intelligence (BI) applications and parallel technologies, such as the computer Vision (CV) and ... as described in part 3rd of the Cloud Extensions series.

Foreword: The network is not absolutely safe, this is a classic famous saying, I also need not say more! Today we'll show you how to download an Access database and prevent Access databases from being downloaded. Attack: First, play your imagination, modify the database file name, theoretically not necessarily prevent the download to modify the database name, the purpose is to prevent us from guessing the database to be downloaded. But in case we guessed the database name, we can download it directly. So this does not guarantee that 100% cannot be downloaded. Guess the common way to solve the database is to write a program to guess the database ...
