Reasonable software process is the foundation of software quality Why is that? Ivar Jacob gave a very vivid example. This is the story of a farmer and his cows. On the way for cows to drink water (called Ox Road), there is a piece of land where cows will eat a lot of crops. After seeing this situation, th

we want to learn a new technology, such as Hibernate, Spring, PhotoShop, WWW, Internet, etc., if you know the problem that these concepts need to solve, Learning these new technologies or concepts will be powerful and fast, and learning a new field can be very quick and effective, using these concepts to explain problems, and even inventing new concepts is easy. Why stress this, because when it comes to architecture, there are times when problems are solved in a new area, and you have to quickl

At a certain time, it is necessary to regularly run an ASP file to execute a task. For example, a factory needs to collect the readings of all electric meters at nine o'clock a.m, of course, this should be connected to various electric meters through in SQL. Now we use an ASP file to concentrate the reading of tables in SQL into ms SQL. You may see a variety of methods to run ASP files on a regular basis, but now I want to talk about a simple method

Swift Optional (Optional) Type basis, swiftoptional Can be empty type, it is certainly not unfamiliar to those who are familiar with C. In C #, the nominal value type cannot be blank. For example, the int type defaults to 0, and the bool type defaults to false. But what should we add to int? Is an empty type. So what about Swift.

On the basis of UNIX Time flies, and I have graduated for almost two years. I feel that I have learned a lot but I am not refined. I think deeply about this and feel it is necessary to serialize unix programming articles to encourage myself to learn.

content in this series will follow this rule. Boundary refers to any face in a n-simplex (n-1)-faces. If the boundary direction is the same as the specified direction, it is recorded as the boundary of "+" and expressed as "+ 1"; otherwise, it is the boundary, it is represented by "-1. Boundary Operators Define the operator P as the boundary operator. When this operator acts on an N-simplex, the result is all its forward boundary. For example, a triangle (a, B, c) has a boundary relatio

components that can be used directly ....; 9. Flume-ng cluster network topology solution: 1. Deploy a flume agent on each collection node, and then perform one or more summary flume agent (loadbalance). The collection is only responsible for collecting data and sending it to the summary, summary can be written to HDFS, hbase, spark, local files, Kafka, etc. In this way, the general modification will only be summarized, with fewer agents and less maintenance work; 2. The collection node
