The below mentioned in the GCC Page for the function sections and data sections options: -ffunction-sections -fdata-sections Place each function or data item into its own section in the output file if the target supports arbitrary sections. The name of the function or the name of the data item determines the section's name in the output file. Use these options on systems where the linker can perform optimizations to improve locality of reference in the instruction space. Most systems using the ELF object format and SPARC processors running Solaris 2 have linkers with such optimizations. AIX

I'm just starting on a website and I already encounter a small problem where I can't find a specific solution to. I wanted to make my website background fit any screen size in width, height does not matter. This is the link to my image: ../IMAGES/background.jpg EDIT I have no idea what's wrong, but for some reason the body doesn't even want to get the background image. It just displays a plain white background. body {background-image:url(../IMAGES/background.jpg);} you can do this with this plugin http://dev.andreaseberhard.de/jquery/superbgimage/ or background-image:url(../IMAGES/background

What is the maximum size for a MySQL table? Is it 2 million at 50GB? 5 million at 80GB? At the higher end of the size scale, do I need to think about compressing the data? Or perhaps splitting the table if it grew too big? I once worked with a very large (Terabyte+) MySQL database. The largest table we had was literally over a billion rows. It worked. MySQL processed the data correctly most of the time. It was extremely unwieldy though. Just backing up and storing the data was a challenge. It would take days to restore the table if we needed to. We had numerous tables in the 10-100 million row

According to android icon design guidelines ( here , see table #1), developer needs to provide status bar icons of next sizes: Status Bar 24 x 24 px (LDPI) 32 x 32 px (MDPI) 48 x 48 px (HDPI) While my measurements show that status bar always has 25 dp in height and expects icons of 25x25dp. This translates to these sizes: Status Bar 19 x 19 px (LDPI) 25 x 25 px (MDPI) 38 x 38 px (HDPI) Here is how I get those size: 25dp * 0.75 = 18.75 => 19px (LDPI) 25dp * 1 = 25 => 25px (MDPI) 25dp * 1.5 = 37.5 => 38px (HDPI) I have confirmed calculated sizes on several Android phones and on emulators.

I'd like to clarify whether it's possible or not to make a div fit its size based on the content's size without having to make elements float or having to make their position absolute. Is it possible? CSS display setting It is of course possible - JSFiddle proof of concept where you can see all three possible solutions: display: inline-block - this is the one you're not aware of position: absolute float: left/right You can use display: inline-block . You can use: width: -webkit-fit-content; height: -webkit-fit-content; width: -moz-fit-content; height: -moz-fit-content; EDIT: No. see http://red

给定一个整数数组 nums ，找到一个具有最大和的连续子数组（子数组最少包含一个元素），返回其最大和。 示例: 输入: [-2,1,-3,4,-1,2,1,-5,4], 输出: 6 解释: 连续子数组 [4,-1,2,1] 的和最大，为 6。 来源：力扣（LeetCode） 链接： https://leetcode-cn.com/problems/maximum-subarray 思路：典型的动态规划问题，但是第一次思考错了，第一次是用f[i]表示前i个数字组合所能得到的最大值，这样决策方式就是三种，最后发现这种并没有满足连续的条件；正确的应该是f[i]表示以第I个数结尾的最大值，这样决策方式只有两种。 错误做法 class Solution { public: int maxSubArray(vector<int>& nums) { if(!nums.size())return 0; vector<int> f(nums.size()); //base case f[0]=nums[0]; //dp for(int j=1;j<nums.size();++j){ f[j]=max(nums[j],max(f[j-1],f[j-1]+nums[j])); cout<<f[j]<<endl; } return f[nums.size()-1]; } }; 正确做法 class

Related, but only talks about the allocated plot space in general, not how to directly set the plot image size and then scale it to fill the desired space Shiny Chart Space Allocation I'm creating a shiny web app and would like to set the size of the plot and scale. What I mean by that is I'm looking for a way to set a finite height/width for my plot, and then scale that set sized image to the mainPanel( plotOutput ()) area. Take this as an example/analogous situation outside of shiny . x <- 1:10 y <- x^2 png("~/Desktop/small.png", width = 600, height = 400) plot(x, y) dev.off() png("~/Desktop
