I am using a SSD with hardly any available space. How do I make it download boxes to another drive? 回答1: You can use the VAGRANT_HOME environment variable to change the vagrant config / box download directory. On Windows you should be able to use the setx command to change it, for example: setx VAGRANT_HOME "D:/vagrant" However, I found a similar stack overflow question where users are suggesting that the

For some reason, it's not valid in Swift to cast a Box<String> (or any other type, for that matter) to Box<Any> . class Box<T> {} var box: Box<Any>? box = Box<String>() // 'String' is not identical to 'Any' In Java there is a ? that represents any type. ( Box<?> ) What can I do here in Swift? 回答1: Short answer is: You cannot cast Box<String> to Box<Any> because there is no relationship between them.

On smaller screens I'd like to have just one column. The content of the other column should be displayed between the two elements of the main column, like shown here: <div class="two-columns"> <div class="main-column"> <div class="red-element"></div> <div class="yellow-element"></div> </div> <div class="sidebar-column"> <div class="green-element"></div> </div> </div> I tried using a flex-box-based

It is hideously slow to build some of the larger projects I have tried out (like 3d engines and such). There are some support for distributed builds with distcc and I have a quad core linux box just standing idle beside it. The question is: is it possible to set up a distcc environment on the linux box that would build ordinary mac objective c or c++ projects, or even iphone projects? Has anyone tried/succeeded in doing this, or is it just not possible? 回答1: Yes,

Is there a simple way to get a tight bounding box around the PDF? 回答1: You can format the bounding box as follows figure(1) hold on; plot(1,1,'x') ps = get(gcf, 'Position'); ratio = (ps(4)-ps(2)) / (ps(3)-ps(1)) paperWidth = 10; paperHeight = paperWidth*ratio; set(gcf, 'paperunits', 'centimeters'); set

Here's the example Fiddle . My goal would be to make sure all the elements have the same height or, at least, the maximum height of the siblings in the row. A row is composed by 3 elements (in this case, no row wrapper exists but I may consider to add such container element). Is there a solution that:

The fix is to eiher restrict blur radius to 10px or filter out the box-shadow from
