In software architecture design, layered structure is the most common and most important structure. Microsoft's recommended layered structure is generally divided into three layers, from the bottom to the following: Data access layer, business logic layer (or to become a domain layer), the presentation layer, as shown in the figure: Fig. 1:3 Layered Structure Data access layer: sometimes called the persistence layer, its function is mainly responsib

Foreman Mode Contractor-Worker mode: I have read a book titled large-scale distributed system architecture and design practices. The "contractor-worker" mode is used in the user module of anycmd. AC is an implicit project. A project has only one contractor. A contractor can hire many workers. A worker is only employed by one contractor under a project. Every work

also very interesting (the original book uses 19 pages of volume to describe the principle and action of the dispenser), smart programmers use a number of techniques to achieve, refer to p568 page.9.10 garbage Collection (recycling)The garbage collector is a dynamic allocator that automatically frees the allocated blocks that are no longer needed by these programs. Garbage collection dates back to the the 1960s early-morning Lisp

In today's society where there are more materials such as Ox hair and more cattle people than data, it is not difficult to use code to make something. If it is a little difficult, just go to various professional forums and various technical groups, everyone will discuss things that are hard to solve. We can learn the technology, but it is difficult to think about it. The same book has different experiences and insights from different people, the ideas

course, I started the attitude is not good, not qualified to give advice to the teacher, even if the mention is also some perfunctory words or make up the words is better not to mention. I can only say that blogging is a good thing though trouble. Other things that you think are important I think the important thing, this semester this textbook election is good, I also study this series of other books, "Neural Network and machine learning", I think for me this does not like readin

minimum value (that is, the best fit to the data) fp1, residuals, rank, sv, rcond = sp.polyfit(x,y,1,full =True) print fp1 FP1 is a two-dimensional array with values of A and B. The printed value is [2.59619213, 989.02487106]. We obtain the linear function f (x) = 2.59619213x + 989.02487106. What is its error? Do you still remember the error function? We construct a function using the following code: f1 = sp.poly1d(fp1)print (error(f1,x,y)) We get a result: 317389767.34 is the result? Not
