Today, using the APK decompile tool to look at your own project generated APK files, found that the code is not confused, so set up with the Proguard confusing code, but the confusion must be in the non-Debug mode will not be effective, even if you are in release mode to Run as startup generated by the APK Package, is still not confused by using Proguard. So decided to export the release version of the APK, the export of "signature" and "not signed" two kinds, have done so, of course, to sign a

I believe that everyone in the web development will encounter garbled problems, there are page garbled, request garbled, database garbled, and so on, here I enumerate the different cases of garbled solution:1. The corresponding data garbled:Just write the phrase in the background interface method to specify that the response character set is Utf-8Response.setcontenttype ("Text/html;charset=utf-8");2. Request data garbled:①.get Request:The first way th
PerfView Overview:Perfview is a tool software that can help you analyze CPU and memory problems. It is very lightweight and does not invade the diagnostic procedure, which has little effect on the diagnostic procedure.Visual Studio's own performance analysis capabilities are well-diagnosed in terms of CPU usage, time consumption, and memory allocation, but Perfview can provide richer diagnostic analysis information.In this article, I will use Perfview
This paper mainly introduces the related problems of logistic regression and the detailed realization method.1. What is logistic regressionLogistic regression is one of linear regression, so what is regression and what is linear regressionRegression refers to the formula known, the unknown parameters in the formula is expected, note that the formula must be known, otherwise there is no way to return theLinear regression refers to the one-time formula
core of C + + to go.Next, in the C + +, the pointer delete delete is worth the problem, this piece is necessary to say:Just send the code up.#include I define an integer pointer p,new an int type integer unit and assign a value of 3 to *p, after that, the address of the output *p and P, after which I am in delete p. In fact, every time we delete actually deletes the value that P points to that space and does not delete its address, the following result is shown:Well, my limited ability can only

). Suppose A, B, and M are integers, m>1. and ab≡1 (mod m) is established, then it is said that A and B are mutually modulo m inverse. In layman's words, if the product of the two-digit modulus m equals 1, it is called an inverse of M.So what's the use of the inverse element? When calculating (b/a)%m, by finding the inverse x of a-mode m, there is (b/a)%m = (b*x)%m = ((b%m) * (x%m))%m is established. This is very useful for solving dividend B's very large p

A friend asked me for help when installing MySQL with Ubuntu Server 16.04 to set up a remote access problem. However, I have not used Ubuntu to install MySQL, so search a lot of technical documents, than the gourd painting ladle. However, due to the differences in the MySQL version, there are some problems with the Setup setup: You cannot access it remotely.
First, install MySQL

. And compared to V8, it simply achieves a pure, fast sort, with no trace of performance optimizations in V8.
Problems with JavaScript array sorting
As we all know, fast ordering is an unstable sort algorithm, and merging sort is a stable sort algorithm. Because of the differences in the algorithm selection of different engines, which lead to the front-end relying on the Array.prototype.sort interface to implement the JavaScript code, in the browser
is no problem to put a Chinese29. What is GC? Why should I have a GC?Answer:GC is the meaning of garbage collection (Gabage Collection), memory processing is where programmers are prone to problems, forgetting or incorrect memory recycling can cause the program or system to be unstable or even crash, Java provides a GC feature that automatically monitors whether an object is out of scope to automatically reclaim memory, and the Java language does not
