On GitHub, you can check it out. Friends of eBay have studied this comparison. Through this project, you can understand that the component of openstack is unstable, such as Nova volume and VNC, which are not integrated. The problem is explained from another aspect.

Ten algorithms to rule the world

, as e-commerce and electronic transactions require these technologies to ensure transaction security. The RSA algorithm is one of the most important cryptographic algorithms. The algorithm was developed by the founders of the same name (Ron Rivest, Adi Shamir, and Leonard Adleman), which makes cryptography ubiquitous and lays the foundation for cryptography. The problem that RSA solves is simple and complex: how to share a public key between a standalone platform and an end user. Its solution i

The "Trinity" interpretation of C + + Reference

C + + is a "all-in-one" language between assembly language and high-level languages. Its ability is that any other high-level programming language based on the VMA(von-Norman architecture) computer cannot be matched, and the performance of only C language can be comparable.However, for a long time, like C + + and hate C + + camp, fight for more than 30 years, who can not persuade anyone. One of the important reasons is that the logic and semantics of C + + are hard to split, and it is difficult

The basis of RSA encryption is a very simple number theory fact: it is easy to multiply two large primes, but it is extremely difficult to factorization the product, so you can expose the product as an encryption key. However, with the maturity of distributed computing and quantum computer theory, RSA encryption security has been challenged.5. Secure Hash Algorithm (SHA)This is not actu

Secure Hash Algorithm (SHA) This is not actually an algorithm, but a series of cryptographic hashing functions developed by the American Institute of Standards and Technology. But this series of functions is the cornerstone of the world's operations. App Store

First of all, the protagonist is of course a plane, there are player planes, wingman on both sides, enemy aircraft. Aircraft are equipped with a variety of weapons: ordinary bullets, missiles, lasers and so on. If it's just a constant plane, the bullets don't change and the plane doesn't change, it's too boring. So we also added props, when the enemy aircr
