If you wrote some struct whatever in C or C ++ style. Please be careful for those in memory bug.1) determine the struct stra {int A; int B; double C ;}; it was used by some software and give it to users based on the memory transformation of the struct. after something happened, stra changedstra {int A; int B; double C; long d ;}; how to judge stra now hold "D" or not? # Ifdef _ win64 # define offsetof (S, m) (size_t) (ptrdiff_t) reinterpret_cast Struct member in memory offset

the problem that needs to be solved at present. At this time, C3 in a new length unit--VW. The description of this unit is: relative to the width of the viewport. Viewport is divided into 100 units of VW, that is, in the 375-width screen, 1vw equals 3.75px,320 screen, 1vw equals 3.2px. So for different sizes of the screen has a unified unit to measure, then we combine REM, that is, the HTML font size FONT-SIZE:CALC (100vw/18.75)-This is the size of the IPhone6 as the design of the calculation,

Let's talk about the Calc () feature. This function allows you to perform simple arithmetic calculations, such as calculating the length of the elements, and eliminates the ability to write JavaScript code that is not easy to maintain. This function supports all simple basic arithmetic operations, including subtraction. For example, you want to create an element that fills its parent element with its width, but it also leaves a portion of the pixel w

This is the past DOS era of the compilation of source code, although has passed, but for the study of the assembly is still helpful, assembly language is just a basic programmer language, most people can grasp, not necessarily in-depth research.

There are many ways to achieve the Grail layout.Mostly with the help of padding, margin, float and the like, of course, this is the traditional way of implementation. More reference ways to the Holy Grail layout summary.This is said to be implemented with CSS3 Cal and Flex, because CSS is limited, there are errors or mistakes, please note.CSS3 Cal Support situation, overall 93%.Support for flex layouts, overall 97%To increase the complexity of1.

This article brings the content is about the CSS3 layout of the multi-column layout box layout Flexible Box layout calc method of usage summary, there is a certain reference value, a need for friends can refer to, I hope you have some help. 1 Multi-column layouts Use a multi-column layout to divide the contents of an element into two or more columns , and make sure that the bottom of the content in each column is aligned. Column-count Property In

Usage:Width:calc (100%-(20px + 2px) * 2); /* Use 100% minus two 20px padding and 2px border*/For Calc (), summarize the following points:1. Compatibility: In ie9+, ff4.0+, chrome19+, safari6+ support is good, mobile side support is not ideal;2. The expression supports addition, subtraction, multiplication and subtraction, and also supports mixed use of units (%, px, EM, etc.);2. In the expression, there must be a space before and after the "+", "-" o

The benefits of the Less needless to say, everyone knows that it does not hurt to write CSS, and I did find some problems when I joined Calc recently in less, which I wrote in less: Div { width:calc (100%-30px); The result less this as an expression, and the result is resolved to me as follows: Div { width:calc (70%); } So, I rewrite less to this: Div { width:calc (~ "100%-30px"); } The parse result is normal: Div { width:calc (100%-30px);

Consider directly selecting n different numbers to easily design a DP F[i][j] = f[i-1][j] + i f[i-1][j-1] The inductive method can prove that F (I,J) is a 2j polynomial about I can be i=1...2n+1 by getting the value of the answer violence DP time

These two days, I finally made up my mind to look at the book. After setting up the development environment, I came into contact with the first hello World Android beginner demo, I have a rough understanding of eclipse-based Android programming

Calc () looks like a JS function, but it is actually a property of css3, it can automatically plan width, height, etc.Usually in the production of the page, always encounter some elements are 100% of the Width. As is known to all, if the element

Original sourceThank the Author ~Faster r-cnn:towards Real-time Object Detection with region Proposalnetworksshaoqing Ren, kaiming He, Ross girshick, Jian SuNSummaryAt present, the most advanced target detection network needs to use the region proposed algorithm to speculate on the target location, such as sppnet[7] and fast r-cnn[5] These networks have reduced the running time of the detection network, then the calculation of the region is a bottleneck problem. In this article, we introduce a r

-CNN algorithm, which introduces RPN network (region proposal networks) extraction proposals. RPN Network is a full convolutional neural network, the proposal can be extracted by sharing convolutional layer features, RPN extracting a image of proposal only need 10ms.The FASTER-R-CNN algorithm consists of two modules: 1.PRN candidate Frame Extraction module 2.Fast

start with a high-level overview, and then we'll cover the specifics of the different components. Starting with a picture, we'll get: A list of borders Each border is assigned a label The probability of each pair of labels and borders Complete Faster r-cnn Frame The input image is characterized by the tensor form (length x Width × height), which is then fed into a pre-trained convolutional neural network to obtain a feature map in the middle layer. Use

the Faster r-cnn:towards Real-time Object Detection with region proposal Networks " Shaoqing Ren, kaiming He, Ross Girshick, Jian Sun --Learning data record (Simon John) The article intends to solve the problem (Towards real-time)The method of extracting proposal (s) from SPP net and fast r-cnn is very time consuming. Therefore, the author proposes that the Regional extraction Network (region proposal Networks, RPN), which and the detection netw

windows, and the recall rate is high, this will not only speed up the target detection speed, but also improve the performance of target detection (less false yang). RPN (Region proposal Networks) was born. The core idea of RPN is to use convolutional neural networks to produce region proposal directly, and the method used is essentially sliding window. RPN's design is ingenious,

Linux c Programming: make compilation 1, linux programming make Compilation There are countless source files in a project, which are classified into several directories according to different functions. makefile defines a series of rules to compile those files first and then compile those files, recompile those files. The biggest benefit of makefile is automated compilation. Once written, only one make command is required, and the entire process is automatically compiled. Greatly improve the dev
