A little trap of the basic knowledge of mathematical statisticsFirst,Mathematical ExpectationsMathematical expectation is also called mean value, expectation, which is called expectation value in physics. In probability theory and statistics, the expectation of a discrete random variable is the probability of each possible result in the experiment multiplied by the sum of its results.Defined:The sum of all possible values of discrete random variables

The white rabbit jumped to the bakery and asked, "Do you have one hundred breads, boss ?" Boss: "Ah, sorry, there are not so many" "That's it ..." The white rabbit left with frustration.

The spatial transformation of ogre is a headache for beginners, And the traps are also a pile of traps. Even if I have climbed out of these traps, I still think it is necessary to talk about them. Translate () this mysterious function. A friend found a trap on the Internet: The following is an incorrect understanding of a netizen in the Forum: Certificate -------------------------------------------------------------------------------------------------

On the NT platform, common applications run in ring3 and the operating system runs in ring0. If you need to execute some privileged commands in the program, the program must be transferred to ring0. Because privileged commands executed by user programs may damage system resources, the operating system provides necessary services to user State programs through the "Gate" mechanism for the purpose of protection and stability. There are four types of X86 doors: interrupt door,

Many tutorials and materials emphasize that a smooth user experience requires asynchronous assistance. The core idea is to ensure that the user's front-end interaction always has the highest priority, so that all time-consuming logic can be put in the background, when everything is complete, inform the front end of a prompt or continue the next step. With. NET development, the promotion of async and await keywords, the steady development of task parallel Library (TPL), and more attention and ado

account for a large proportion of such websites because the user group they are interested in isHigh-end business personnelAnd such groupsThe most insignificant social networking needsIn addition, relying on the network to expand the workplace network cost is too low, quality and credit lack of assurance, it is still very unreliable at this stage. At present, the rapid decline in user quality of such websites can be said to be evidence.Other directions outside of business can be said to be a co

Introduction The DLL trap is a strange problem. I believe that many users have such experiences. If your experiences were originally designed to run today, after you installed a new experience, all of a sudden, the power supply cannot work. This is not a problem with your hardware or application process.But the lack of design for business systems, this is usually because the new application version overwrites the shared program library (DLL) and often

Translator: You might think Java is very simple, the equals implementation of object will be very simple, but the fact is not what you think, after reading this article patiently, you will find that you know so little about Java. If this article is a Java Programmer's entry test, then I don't know how many people will fall into such a trap. Summary This article describes the technique of overloading the Equals method, which can guarantee the correct

The range-based loop of C + + is a new feature of c++11, and it is convenient to replace the for loop usage of iterators to some extent. However, a range-based for loop has a hidden trap that can cause serious memory errors if you are not aware of it.Examples ShowLook at the following code:1#include 2#include string>3 4 using namespacestd;5 6 structMyClass7 {8 stringText ="MyClass";9 Ten stringGetText () One { A returntext; - }

time by 1000*1000 times, which results in a huge amount of CPU idling pressure.Having analyzed so much, actually look at the Timeunit class in the JDK to the Convert method, it is easy to understand: /** * Converts the given time duration in the given unit to this unit. * Conversions from Finer to coarser granularities truncate, so * lose precision. For example, converting {@code 999} milliseconds * to seconds results in {@code 0}. Conversions from coarser to * finer granularities with argum

browsers are smart-aleck optimizations. Maybe people don't quite understand where the test results differ from ... The answer is that test is the same as exec if there is a/g behind the direct quantity. If the global global lookup parameter is set, the same test object records the index position of the last matching character. The next time it matches, it starts at this point. If there is no matching index So it's OK to use exec in the above test. So how do you avoid browser differences her

Tags: creating tables rem span instance auto INCR statement dataIn MySQL, the syntax for creating tables in a database is as follows: 1 CREATE TABLE TableName ( 2column_name_1 column_type_1 constraints, 3column_ name_2 column_type_2 constraints, 4 ... 5 column_name_n column_type_n constraints, 6 PRIMARY KEY (column_name) 7 ); Where TableName is the table name, COLUMN_NAME is the column name, Column_type is the data type of the column, constraints is the related constraint.

But this writing hides a deeper use trap. In the case of data duplication in a sorted field, it is easy to get the problem that the sorting result is inconsistent with the expected. For example

In this article, I would like to introduce a very important and interesting feature in Java, that is, automatic boxing and unboxing, and from the source code to interpret the principle of automatic boxing and unboxing, and this feature also left a trap. Developers can easily fall into this trap if they don't pay attention. Automatic Boxing (autoboxing) Defined When you write Java programs in peacetime, y
