Bash: Terminate on Timeout/File Overflow while Executing Command

China☆狼群 提交于 2019-12-02 20:06:33
问题 I'm writing a mock-grading script in bash. It's supposed to execute a C program which will give some output (which I redirect to a file.) I'm trying to (1) make it timeout after a certain duration and also (2) terminate if the output file reaches a certain file size limit. Not sure how to go about either of these. Any help? Thanks. 回答1: There's a GNU coreutil command timeout to do timeouts. Investigate ulimit -f 32 to set the maximum file size (to 16 KiB; it counts in 512 byte blocks).

What happens when HashMap or HashSet maximum capacity is reached?

隐身守侯 提交于 2019-12-02 19:11:19
Just a few minutes back I answered a question asking about the " Maximum possible size of HashMap in Java ". As I have always read, HashMap is a growable data-structure. It's size is only limited by the JVM memory size. Hence I thought that there is no hard limit to its size and answered accordingly. (The same is applicable to HashSet as well.) But someone corrected me saying that since the size() method of HashMap returns an int , there is a limit on its size. A perfectly correct point. I just tried to test it on my local but failed, I need more than 8GB memory to insert more than 2,147,483

css footer position stick to bottom of browser?

随声附和 提交于 2019-12-02 18:33:50
I'm having a problem with my site http://artygirl.co.uk/pixie/about/ I can't seem to get the footer to automatically stick to the bottom of the browser, and show the rest of my background. Is there a solution better than using position:fixed or absolute? I think there are possibly other styles over-riding some tests I do in firebug. Thanks for your help Regards Judi Steve This is always a bit difficult, you could increase the min-height of your content area, but even then if someone has a really big screen you'd see the same thing. You could use a bit of JavaScript to increase the min-height

Responsive vertical center with overflow hidden

只谈情不闲聊 提交于 2019-12-02 18:21:56
After searching both Stack Overflow and Google I still wonder how to vertical center a image that is bigger than it's parent element. I use no height, just max-height, because I want to make a responsive solution, without jQuery. If possible. Here is some code: <div style="max-height: 425px; overflow: hidden;"> <img src="http://img.youtube.com/vi/jofNR_WkoCE/maxresdefault.jpg"> </div> Alexandru Diacov to center vertically an bigger image u can use the construction and css bellow <div class="img-wrapper"> <img src="http://img.youtube.com/vi/jofNR_WkoCE/maxresdefault.jpg"> </div> And css: .img

.one { text-align: center } 多行文本: .multi { overflow: hidden text-overflow: ellipsis display: -webkit-box -webkit-line-clamp: 3 -webkit-box-orient: vertical }不过可惜的是兼容性太差,可以用下面的这个 .multi-text{ width: 50%; height: 4.5rem; line-height: 1.5; padding: 20px; background: lightblue; overflow: hidden; position: relative; box-sizing: border-box; &::after{ content: '...'; height: 1.5rem; position: absolute; bottom: 5px; right: 5px; } } 来源: https://www.cnblogs.com/jack123/p/11757386.html

清除浮动的四种方式及其原理理解 本文介绍了四种清除浮动的方法,并尝试解释其原理。在理解了各种清除浮动的原理之后,你会发现,很多清除浮动的方法本质上其实是一样的。掌握这些原理,相信你可以根据场景和需求,灵活运用原则发展出不同的清除浮动的方法,而不再死记或拘泥于文中提到的方法。 一、为什么要清除浮动 在讲清除浮动的方法之前,我们先来了解一下为什么要清除浮动,清除浮动的目的是什么,即,要解决什么样的问题。来看一个浮动的例子(略去了文字内容): <div class="topDiv"> <div class="floatDiv">float left</div> <div class="textDiv">...</div> </div> <div class="bottomDiv">...</div> 其样式为: .topDiv { width: 500px; border: 2px solid black; } .floatDiv { width: 100px; height: 100px; border: 2px dotted red; color: red; margin: 4px; float: left; } .bottomDiv { width: 500px; height: 100px; margin: 5px 0; border: 2px dotted black; }

Carry Flag, Auxiliary Flag and Overflow Flag in Assembly

你说的曾经没有我的故事 提交于 2019-12-02 18:18:56
I Cannot seem to tell the difference between the Carry Flag, Auxiliary Flag and Overflow Flag in Assembly. I'm currently studying it in school and the teacher didn't go into any details. Please help me to understand, I will be needing it for the exam. I will be really grateful!! From what I seem to know by now is that the Carry Flag is used when you try, let's say, 255+9 when you only have 8 bits for data, The Auxiliary Flag is the same, but only for the 4 last bits?? And The Overflow is used when you have 7 bits for the binary number and the 8(left-most ) is used for the sign??? Michał

AppCompat Toolbar: Change Overflow Icon Color in ActionMode

回眸只為那壹抹淺笑 提交于 2019-12-02 17:33:48
With the AppCompat Toolbar, I want to be able to change the color of the overflow menu icon on ActionMode change. For example, the overflow icon will be white in normal Toolbar mode. And will turn black on ActionMode. So far, I have managed to change the background of the action mode as well as the title text. But I have yet to find a way to change the overflow menu icon color. I know that there's an answer available: Change ActionMode Overflow icon I tried the first solution and I wasn't able to find the overflow icon. The second solution, even with a 50L delay causes the overflow menu icon

Overflow: overlay doesn't work in firefox

对着背影说爱祢 提交于 2019-12-02 17:26:22
On my website I need to use the css property overflow: overlay for a <div> . However, it is not rendering in the browser and an inspection of the css in firebug shows that it isn't even there, but it is as it works in Chrome. I havn't tested out safari. What must I change to get the overflow: overlay css property working? Thanks Possible values for overflow are: visible hidden auto scroll See here or here for a discussion of these. Using any other value in different browsers will yield unpredictable results as they handle the incorrect value differently. Edit : Following the comment, I've

CSS布局(四) 左右布局

本文是根据网上资料总结出来的文章 左边固定,右边自适应的两栏布局。 基本样式 <div class="wrapper" id="wrapper"> <div class="left"> 左边固定宽度,高度不固定 </br> </br></br></br>高度有可能会很小,也可能很大。 </div> <div class="right"> 这里的内容可能比左侧高,也可能比左侧低。宽度需要自适应。</br> 基本的样式是,两个div相距20px, 左侧div宽 120px </div> </div> .wrapper { padding: 15px 20px; border: 1px dashed #ff6c60; } .left { width: 120px; border: 5px solid #ddd; } .right { margin-left: 20px; border: 5px solid #ddd; } 通过width: calc(100% - 140px)来动态计算右侧盒子的宽度。需要知道右侧盒子距离左边的距离,以及左侧盒子具体的宽度(content+padding+border),以此计算父容器宽度的100%需要减去的数值。同时,还需要知道右侧盒子的宽度是否包含border的宽度。 .wrapper-inline-block { box-sizing:
