How to place two divs side by side where one sized to fit and other takes up remaining space?

阅读更多关于 How to place two divs side by side where one sized to fit and other takes up remaining space?

问题 This should be easy... why is this not easy? I am looking to have 2 divs side by side, where one div will auto size to the content inside and the second div will simply fill the remaining width. I need the text in the 'remaining width' div to be truncated if it is too large though, as I can only have these divs occupy one line. I have been searching all day and the closest I found was this post which suggested using tables that STILL didn't fix the issue. Here is the jsfiddle code that

How is 64-bit math accomplished on a 32-bit machine?

阅读更多关于 How is 64-bit math accomplished on a 32-bit machine?

问题 If a 32-bit processor is, indeed, really only 32 bits in length, then how can math operations work on 64-bit numbers? For example: long lngTemp1 = 123456789123; long lngTemp2 = lngTemp1 * 123; According to MSDN, a long in C# is a signed 64-bit number: http://msdn.microsoft.com/en-us/library/ctetwysk(VS.71).aspx How is it that a 32-bit Intel Microprocessor can execute code, like the above without getting an overflow? 回答1: They use the carry bit for add and subtract. The assembler ops for "add

CSS控制的内容超过容器宽度后显示省略号...

阅读更多关于 CSS控制的内容超过容器宽度后显示省略号...

一般我们看到的比如新闻列表，为了使文字不回行，控制字数，会通过程序让多余的字符显示省略号，我们只使用CSS可以达到同样的效果，虽然不完美。 li { width:50px; white-space:nowrap; text-overflow:ellipsis; overflow: hidden; } 首先是一个容器，可以是div,li,td等等，先定义宽度，“white-space:nowrap”是强制在一行内显示所有文本，不回行。“text-overflow:ellipsis”就是关键了。 text- overflow是CSS3新增的属性，IE6以上版本支持。它可以带2个参数：clip [不显示省略标记（...），而是简单的裁切]，ellipsis[当对象内文本溢出时显示省略标记（...）]。所以，这个方法是不支持Firefox 的。因此，我们还要加上一句overflow: hidden，让多余文字在ff中隐藏。虽然打到了效果，但是因为用程序控制这种效果也很方便，而且没有浏览器兼容性的问题，所以用CSS控制的方法就显得鸡肋了。来源： https://www.cnblogs.com/xhyang110/archive/2009/08/20/1550603.html

How do I stop internet explorer's propriety gradient filter from cutting off content that should overflow?

问题 I'm using the internet explorer gradient filter in my CSS. It was all going well until I noticed that images that are supposed to extend beyond their containers overflow:visible; are getting clipped as though the container was set to overflow:hidden; I have no idea why this would happen, or how to fix it. Can anyone help? I'm looking at it in IE8 and IE7 This is the css causing the issue, when I comment it out, no more bug: .box{ filter: progid:DXImageTransform.Microsoft.gradient(GradientType

目录什么是 map 为什么要用 map map 的底层如何实现 map 内存模型创建 map 哈希函数 key 定位过程 map 的两种 get 操作如何进行扩容 map 的遍历 map 的赋值 map 的删除 map 进阶可以边遍历边删除吗 key 可以是 float 型吗？总结参考资料这篇文章主要讲 map 的赋值、删除、查询、扩容的具体执行过程，仍然是从底层的角度展开。结合源码，看完本文一定会彻底明白 map 底层原理。我要说明的是，这里对 map 的基本用法涉及比较少，我相信可以通过阅读其他入门书籍了解。本文的内容比较深入，但是由于我画了各种图，我相信很容易看懂。什么是 map 维基百科里这样定义 map： In computer science, an associative array, map, symbol table, or dictionary is an abstract data type composed of a collection of (key, value) pairs, such that each possible key appears at most once in the collection. 简单说明一下：在计算机科学里，被称为相关数组、map、符号表或者字典，是由一组 <key, value>

overflow: hidden; width: 50%; heigth: 0; padding-bottom: 50% 1、如果一个元素的height值为百分比，则其高度是相对于父元素的宽度而言，对于padding-bottom和padding-top也是。 2、计算overflow时，内容区域和padding区域都会计算进去，即使设置了overflow：hidden，padding区域也会显示。综上所述，可以用padding-bottom来代替高度，将height设置为0，实现固定宽高比例来源： https://www.cnblogs.com/hengruo/p/12162213.html

GNU buffer overflow using malloc

问题 I am running in a loop the following function: int* rpermute(int n) { int* a = malloc(n * sizeof(int)); int k; for (k = 0; k < n; k++) { a[k] = k; } for (k = n - 1; k > 0; k--) { int j = rand() % (k + 1); int temp = a[j]; a[j] = a[k]; a[k] = temp; } return a; } If I set a new int variable in my code every variable is changing, I assume it is a buffer overflow problem. Running the valgrind i get the following: ==4459== 73,036 bytes in 19 blocks are definitely lost in loss record 1 of 1 ==4459=

Overcoming the x86 idiv #DE exception

阅读更多关于 Overcoming the x86 idiv #DE exception

问题 Re: x86 assembly language - I have three 32-bit signed numbers: n1, n2, and n3. I want to imul n1 by n2 to get a 64-bit signed result. I then want to idiv that 64-bit result by n3. The problem is that if the 64-bit signed result is large enough and/or if n3 is small enough, an overflow will result and idiv will throw a #DE exception. If idiv simply set #DE on overflow, I could check to confirm that ((n1 * n2) / n3) * n3 + ((n1 * n2) mod n3) = (n1 * n2). If not, overflow would have occurred

math overflow for a not very overflowing calculation in python

阅读更多关于 math overflow for a not very overflowing calculation in python

问题 The calculation for which I'm getting the math overflow number is: e2 = math.exp([[-20.7313399283991]]) There are actually more extreme numbers that I've done than this, why is this causing an overflow? I get this error: OverflowError: math range error 回答1: math.exp() operates on scalars, not on matrices. You can use it like so, without the square brackets: >>> math.exp(-20.7313399283991) 9.919584164742123e-10 If you need to operate on a matrix, you could use numpy.exp(): >>> numpy.exp([[-20
