Ten algorithms to rule the world

platform and an end user. Its solution is encryption. 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 actually an alg

A detailed introduction to the basic concepts of OpenStack Keystone _openstack

Understanding the basic concept of OpenStack Keystone Keystone Introduction Keystone (OpenStack identity Service) is the OpenStack framework for authentication, service rules, and service tokens, which implements the OpenStack identity API. Keystone is similar to a service bus, or the entire OpenStack framework registry, where other services register the endpoint of their services (the URL of the service access) through Keystone, the invocation of any service to each other, and the need for Ke

Basic how-to tutorials for using subqueries and scalar queries in Mysql _mysql

MySQL Sub-queryA subquery is an intermediate result of the query result of a SELECT statement, which is invoked by another SQL statement. MySQL supports all of the subquery formats and operations required by the SQL standard, and also extends several unique features.The subquery has no fixed syntax, and the example of a subquery is as follows: SELECT * from article where UID (select uid from user where Status=1) The corresponding two data tables are as follows:Article Article table

Rethinking the Origins of the universe

single point-imagine flattening the earth and stuffing it into a small ball of peanuts-we call this point singularity. So the beginning of the story is that an invisible film called the event horizon revolves around the singularity, and crossing this boundary means you'll never be able to come back again. That's why a black hole's gravitational pull is strong enough to make it possible for anything to escape. The reason why black holes are so strange is because it makes two fundamental theorie
