If the activity is not in the background task stack, a acitivyt is recreated and placed separately into a task stack, which is actually added to the intent that launches the acitivity.A task is a stack that contains a series of activity, followed by the advanced post-out principle.Task default behavior:(1) Premise: Activity A and Acti
Bayesian statistics are based on conditional probability, joint probability, so we start with probability, conditional probability, joint probability, then Bayesian theorem, and finally a Bayesian application--spam filteringProbability: The likelihood of an event occurring, such as tossing a coin, the likelihood of a positive upward being 50%, and the probability of a dice point of 6 being 1/6. We use the notation as P (A)Conditional probability: satisfies the possibility that the event occurs u
. In this case, the corresponding members of each stage should evaluate the reasonable time for their work in the corresponding stage (of course, this is evaluated on the premise that the demand has been finalized ). What the product manager should do is to reasonably assess the time ratio of each stage and the overall coordination of the project schedule. In this case, each member is responsible for his/her evaluation work time and must complete his/
-matrix is optimized by singular value decomposition, and the inverse R1 R2 does not necessarily satisfy the orthogonal condition, nor does it meet the equal-length condition. So, we're going to fit the RT matrix once more.The goal of this fitting is min (Ros3-r '). where r ' = [k-1h (:, 1:2) x].The method is still singular value decomposition, R = UV '. This is the second occurrence of singular value decomposition.2. Estimation of position and pose by projective transformationThe
distribution, if the group design, the individual is independent of each other, Both groups of data were taken from the general distribution and the homogeneity of variance was satisfied. These prerequisites are required because the T-Statistic must be calculated under such a premise, and T-Test is based on the T-distribution as the theoretical basis of the test method.In short, the practical t-test is conditional, one of which is to conform to the h

The reason for writing this article stems from some technical discussions within the group. In fact, effective Java's item 37 has discussed marker Interface in detail. But from the whole item's point of view, it is in fact a positive attitude to the series of advantages and special features provided by marker interface. So a lot of people, including my colleagues, have taken some of the conclusions of the article as criteria for execution, ignoring the premi
Title Description:G company has n a circular arrangement of warehouses along the railway transport lines, each warehouse stores the quantity of goods varies. How to use the least amount of transport can make n warehouses of the same inventory quantity. When transporting goods, they can only be transported between adjacent warehouses. For a given n-ring-lined warehouse inventory, programming calculates the minimum amount of transport for the same quantity of inventory in n warehouses.Model Analys

I. What are the prerequisites for website optimization?As a matter of fact, many webmasters do not know what SEO is. As a result, they follow the same pattern to optimize SEO. Binary is not just nonsense, and there are a lot of people doing this. For example, some enterprise websites hire SEO supervisors, but do they understand what SEO means? In fact, many people think that SEO is an external link. Some people around them apply for SEO talents. They just add external links to their websites. If
Tip: The attachment provided later in this article is a pretty good extension plug-in for Flash CS 6.0 that I found on the Internet. It was modified based on the original dragonbone 2.0, to cause more types of animation files that match COCOS2D-X development. Of course, some animation files can be imported into cocostudio (for example, 1.4.0.1 used in my lecture) for further modification.

In the past year, it has taken a lot of time to consider server architecture design issues. I have read a lot of articles and have studied many open-source projects, but I have broadened my horizons. However, I have not helped much in online game architecture design. Foreigners are still playing many console games, and MMO games are not as involved as widely as in China. Let's take a look at the two books massively multiplayer games development 1 2. the quality is very general, and the help is
Solve JS cross-origin problems
Article category: Web Front-endHow to solve JS cross-origin problems
Javascript cross-origin is one of the most common problems for Web developers. The so-called JS cross-origin problem refers to the Access to Data Objects in another different domain through JS on a page in one domain. For security consideration, almost all browsers do not allow this cross-origin access, this causes cross-origin web services to become a problem in some Ajax applications. Currently,

Project management personnel with rich implementation experience concluded that the implementation of software projects in China must be carried out through consulting: to launch their own solutions, rather than making projects based on the customer's requirements. This is a good solution, but it cannot solve the problems of all implementation
