1. Boxing, unpacking or aliases many of the introduction of C #. NET learning experience books on the introduction of the int-> Int32 is a boxing process, the reverse is the process of unpacking. This is true of many other variable types, such as short <-> int16,long <->int64. For the average programmer, it is not necessary to understand this process, because these boxes and unboxing actions can be automatically completed, do not need to write code to intervene. But we need to remember that ...

Describes the use of unmanaged Win32apis encryption to decrypt data before. NET is a very painful thing to do. For the purpose of this cryptographic decryption. NET is configured with a set of classes (and namespaces). Now you have a lot of classes that can protect your data using each of these different algorithms. There are 3 types of encryption methods defined within the. NET Crypttography namespaces. They are asymmetricalgorithm,symmetricalgorithm and HashAlgorithm. All the ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

We know that PGP (pretty) is the most popular kind of encryption software at present, it is a mail encryption software based on RSA public key encryption system. We can use it to keep the message confidential to prevent unauthorized reading, and it can also digitally sign the user's message so that the recipient can be sure of the sender's identity. It allows users to communicate securely with people they have never seen before, without requiring any secrecy to pass the key, because it uses an asymmetric "public key" and "private key" encryption system. But PGP is not a completely asymmetric addition ...

This article mainly introduces some principles and background knowledge about PGP implementation. Other documents on the installation and use of PGP refer to other documentation provided with this article. PGP pretty-Privacy is a mail encryption software based on RSA public key encryption system. You can use it to keep your emails secret to prevent unauthorized reading, and it can also digitally sign your emails so that the recipient can be sure you sent them. It allows you to safely communicate with people you've never seen before, and you don't need any confidential channels to pass the secret.

PGP is a mail encryption software based on RSA public key encryption system.

It allows you to safely communicate with people you've never met before, and you don't need any confidential channels to pass the keys. It uses: Prudent Key management, a RSA and traditional encryption of the hybrid algorithm for digital signature of the message digest algorithms, encryption, and so on, there is a good ergonomics design. It's powerful and fast. And...

While some players are enjoying the new additions to patch 3.3.5, many are still barred from their doors-because there is a system problem that can cause the crash of the game. Blizzard has noticed the problem and has been fully committed to fixing it. At the same time, the official Technical Support forum also posted a blue post on the issue, which mentions how players can make the game run again. For now, this seems to be an "insufficient access" error when the player runs wow under the 64-bit operating system. What else can you do while waiting for the fix?

Now the network advertising, the development of space is still very large, because they put 99% of the money space are thrown away. With the development of large data, the money will be picked up by the next generation one by one. 　　At that time, people will know more clearly about the truth from precision to recommendation. Future advertising will be like this, advertising for different people, presenting different content. 　　By this precise measure, almost all advertising is now obsolete in the future. Precision is relative to the needs of consumers. Because it is not accurate, so consumers do not need. The accurate question is how to really dig out the consumer ...

Last month, Google officially put "similar image search" on the homepage. You can use a picture to search all the pictures on the internet similar to it. Click on the camera icon in the search box. A dialog box appears. You enter the Web site, or upload the image directly, Google will find its similar image. Here's a picture of American actress Alyson Hannigan. After uploading, Google returned the following results: Similar "similar image search engine" There are many, TinEye can even find photos ...
