These days, the interview, the interview when a lot of knowledge point is also very unfamiliar, this two days first to review the Java Foundation, there is a period of time did not write a blog, today, first talk about the conversion of the system.1. Binary number of the original code, complement and anti-code1): For positive number of the original code, complement and anti-code are the same, not discussed here.2) Next we discuss negative binary sourc

Recently learning COCOS2DX, just started to write a tower defense game, because the first time with VS2012, feel not too accustomed. Most of C's content has also been forgotten, so do a brief review. 1.

MIPS series processor bootloader, mainly by the MIPS company developed the core code, using MIPS kernel development application processor manufacturers will be based on the development of MIPS company core code Yamon to expand their code, Sigma Design smp8xxx The bootloader of the HD multimedia processor is this implementation, which compensates for U-boot's lack of support for MIPS processors. In a sense, Yamon is an option for MIPS processor bootloader.Finally,

By the November, half of the semester, and the "Information Security system Design Fundamentals" This course also to the midterm.

Foreword: read so many people's blog article, and subscribed to a lot of bloggers of the public number, they have written the idea of the blog, but by various excuses to blow (for example, the language does not have words, etc.), have not been able to adhere to, think oneself is enough. Today, from the beginning of the basic knowledge of Java review, regularly write blog, is to give yourself a cruel and confessed! You insist, say a word to yourself: l

From this beginning, plan to review the basic knowledge of data structure. One is to find a job after a year, and the other is to improve their programming skills. Since these data structure knowledge points have been learned before, here we refine the core of each knowledge point, as well as the code implementation.This first says the insertion sort in the sorting algorithm. Insertion Sorting is a sort of stable sorting algorithm, which belongs to t

A review of Part1 regression basisThere are many kinds of regression methods, the most common is linear regression (there are also one and multivariate), polynomial regression, nonlinear regression. In addition, we will briefly explain the methods of testing the predicted results.Linear regressionUnary linear regression is the simplest and most common regression model, similar to the one-dimensional equation in junior mathematics, and its basic model

This review bubbles the sort.Bubble sort is also a sort of stable, internal sort.Bubble sort of the basic idea: to the current is not well-sequenced range of all the number, from top to bottom of the adjacent two numbers in turn to compare and adjust, so that the larger number to sink, smaller upward. That is, each time a comparison of two adjacent numbers finds that they are in the opposite order of order, they are interchanged.Insert sort faster tha

This year, the domestic anti-virus software is still free for the theme, the domestic three kill soft manufacturers in the rising and Jinshan has entered the free camp, only the remaining jiangmin a struggling support, have to say that this is Zhou 祎 alive to force.

Recently ready to move, but also to review the basic knowledge. After a year, the front just contact with the Springboot can only be released first. Just review what you have listed.the elements in Set cannot be duplicated , So what is the way to distinguish between duplicates or not? is to use == or is equals ()? What difference do they have ? ? with contains to distinguish whether there are duplicate obj
