On the audio voice changer algorithm, this is a topic that many people are particularly interested in. Of course, there are many open-source algorithms to learn, there are time-domain-based, but also based on the frequency-domain algorithm. The final algorithm wants to achieve the same purpose. Recently there are many netizens asked about the voice changer algorithm some of the details of the problem, e-mail asked me. To give a more reasonable or easy-to-understand explanation, seemingly sim

We recommend 2 kinds of deletion methods I have used before. Execute

statements and committing SQL statements in batchesIf you need to perform a large DELETE or INSERT query on an online website, you need to be very careful to avoid your actions to keep your entire site from stopping accordingly. Because these two operations will lock the table, the table is locked, the other operations are not in.Apache will have a lot of child processes or threads. So, it works quite efficiently, and our servers don't want to have too many child processes, threads and database

A few days ago in the forum sent the following article, "Big picture inside looking for small figure ah look for small figure ~~~~~[help thinking", the purpose is to find out a large map of a small picture of the number and location information. Maybe there is no good way to do it, and in the end I will use a less efficient way to solve the problem. The main ideas are: 1, the large map of the RGB value of each pixel into a matrix. So we're going to ge

data integrity is ensured, and the relationship between the data elements is clearly expressed. In the case of multi-table correlation query (especially big data table), its performance will be reduced, but also improve the programming difficulty of the client program, therefore, the physical design needs to compromise, according to business rules, determine the data size of the associated table, the frequency of access to data items, This kind of da

The amount of information in modern society is growing at a rapid rate, and there is a lot of data accumulating in it. It is expected that by 2025, more than 1/3 of the data generated each year will reside on the cloud platform or be processed with the cloud platform. We need to analyze and process this data to get more valuable information. In the future of "smart cities", there will be more and more structural and unstructured data. So how do we store and manage this data efficiently, and how

With the development of social platforms and the popularization of mobile smart terminals, the explosion of massive data is no longer the static images, text, audio, and other files in the database, it has gradually evolved into a powerful resource for enterprise competition, and even the lifeline of enterprise development. IBM has talked about the concept of 2B several years ago. Today, big data can help enterprises strengthen their competitiveness.
