Specify/Set width and height on a react-boostrap modal

由 蹲街弑〆低调 提交于 2019-12-06 23:18:35
问题 How can I apply a dynamic width and height to a react-bootstrap modal window? I have checked the react-bootstrap docs here but could not figure out how to do that. Actually the value of width and height props would be dynamic (could be any values) as this will be a reusable component in my app (to be used on many pages) thus can't apply width/height through some CSS class. 'bsSize' property as mentioned in docs also not working, although predefined sizes of xs, md, lg is not what I exactly

linux修改max user processes limits

说明： 这篇是网上看到的有关修改max user processes limits，觉得还可以，就保留了下来！稍微加了点东西 具体： 最近新上了一批服务器，内核升级到了2.6.32版本，部署完MySQL实例后上到线上，直接负载冲到15，cpu使用达到700%。 01:20:01 PM runq-sz plist-sz ldavg-1 ldavg-5 ldavg-1503:50:01 PM 34 1506 22.95 18.11 11.7801:20:01 PM CPU %user %nice %system %iowait %steal %idle03:50:01 PM all 95.13 0.00 3.31 0.06 0.00 1.49 当时就有点蒙，io并不是瓶颈，业务也米有变更，线上的服务器都运行正常，为什么这台新机器就变成这个模样了呢？ 最后才发现又是一个ulimit的坑啊，之前对于ulimit -n已经碰了多次头，这次又差点碰的头破血流，万幸灰度上了1台slave，并没有影响到线上。 这次碰到的问题是ulimit -u，这个-u是做什么用的呢？ core file size (blocks, -c) 0data seg size (kbytes, -d) unlimited scheduling priority (-e) 0file size (blocks, -f)

Default UIPickerView height

由 安稳与你 提交于 2019-12-06 18:29:48
问题 How can I programatically obtain the default height of an UIPickerView instance, in accordance to the resolution and orientation of the device that the app is currently running on? I would like not to use a hardcoded value for this parameter, in the event that new devices will support different screen resolutions and thus will determine this component to have a different default size. 回答1: The warning that André saw doesn't seem to happen anymore (XCode 4.2; iOS SDK 5.0). If you create it

Scale down to fit an image in FOP

由 余生长醉 提交于 2019-12-06 18:11:18
问题 I am using FOP version 1.0 to create PDFs. In one of the pages I'd like to display an image (2552 x 4200 pixel) and scale it down if it doesn't fully fit on the page. As far as I could see on the mailing list the recommended way of doing this would be following: <fo:external-graphic inline-progression-dimension.maximum="100%" content-height="scale-down-to-fit" content-width="scale-down-to-fit" src="..."/> Unfortunately, that still doesn't display the whole image. The lower part of the image

how can delphi 'string' literals be more than 255?

由 好久不见. 提交于 2019-12-06 16:41:50
问题 im working on delphi 7 and i was working on a strings, i came across this For a string of default length, that is, declared simply as string, max size is always 255. A ShortString is never allowed to grow to more than 255 characters. on delphi strings once i had to do something like this in my delphi code (that was for a really big query) var sMyStringOF256characters : string; ilength : integer; begin sMyStringOF256characters:='ThisStringisofLength256,ThisStringisofLength256,.....' //length

size of node with shape=circle

由 ▼魔方 西西 提交于 2019-12-06 16:36:33
问题 i'm trying to set the size of the nodes this way: controller[shape=circle,width=.5,label="Controller",style=filled,fillcolor="#8EC13A"]; But all three nodes are with different size. How can i set fixed size? 回答1: From the DOT Guide http://www.graphviz.org/pdf/dotguide.pdf on page 4 it says the following: When drawn, a node’s actual size is the greater of the requested size and the area needed for its text label, unless fixedsize=true , in which case the width and height values are enforced.

Android splash screen dimensions

由 怎甘沉沦 提交于 2019-12-06 16:07:41
I'm trying to create a splash screen on photoshop that will support every single device that runs Android. I've been reading around blogs and the android website and I see that you need to design your assets in dp, but I don't understand what that means. I understand the concept of dp, but I don't understand how to apply that on photoshop. I know the equivalent of a dp is pixels/(dpi/160), but I'm not sure what size (pixels) I should be using for each one of the different sizes (ldpi, mdpi, hdpi, xdpi, xxdpi...). So if someone can let me know what the dimensions of my splash screens needs to

reduce size of PDF generated with FOP

由 有些话、适合烂在心里 提交于 2019-12-06 15:55:10
I have unsuccessfully browsed this site (that has so often saved my life in the past) and the web for an answer to this question: I use Java, XSL-FO and FOP to generate PDFs that consist in one or more pages of data and images, each page having a header and a footer containing images themselves. These header and footer are repeated on each and every page of the PDF documents. The images are responsible for a large part of the size of the resulting PDF (about 50 %). I noticed that, by converting them from JPEG to TIFF, and by reducing their resolution, I was able to reduce considerably the size

Where to find the evidence of how to calculate the size of a java object

由 浪子不回头ぞ 提交于 2019-12-06 15:10:01
I've searched about the size of a java object for a long time, there are a lot of answers like this , everyone is telling me that the size of the overhead of a java object, and how to calculate out the actual size. But how do they know that? I did not find any evidence from the official oracle documents. What is the evidence for that conclusion? Or the data was just come from some guesses based on some experiments? Another thing. It is mentioned in the official document that there is a 'approximative' way to measure the object - the Instrumentation way, can anybody explain to me what is the
