load

问题 I'm working on a small function, that gives my users a picture of how occupied the CPU is. I'm using cat /proc/loadavg , which returns the well known 3 numbers. My problem is that the CPU doesn't do anything, right now, while I'm developing. Is there a good way to generate some load on the CPU, I was thinking something like makecpudosomething 30 , for a load of 0.3 or similar. Does an application like this exist? Also, are there any way to eat up RAM in a controlled fashion? 回答1: I didn't

问题 I'm loading a 5MP image into an UIImageView calling self.imagecontainer.image = myUIImage . myUIImage is an image coming from the camera of the iPhone. This takes some time before the image can be seen on screen, and even if I can reduce this time, I need to start a process when the image is really displayed on the screen. How may I know that the image is loaded and displayed, and not just still being processed by the UIImageView ? 回答1: Well... first thing is you shouldn't be setting a 5MP

问题 I need to load a xml file from my pc in ajax, but the script it's not working at it's current state(no clue why). Here is what i have: $.ajax({ type: "GET", url : 'file:///C:/xampp/htdocs/files/license/index_skin.xml', dataType: "text", success : function (data) { $("#txarea").val(data); } }); 回答1: There are multiple issues in play here: File URLs don't use the exact window path names c:\xxx .

问题 I have this problem which i find a bit difficult to explain but I will try: I have a page which fades in and out some divs taken from other pages with the load() function on click event. One of this divs contain a selection of pictures showed using Jquery.Cycle . Although on the page itself the jquery.Cycle works ok, when imported in to the page it does not. Hope my explanation is clear. The code for importing is this: $('#wrapper a').live("click", function(evt) { evt.preventDefault(); var

问题 Update: I originally had document.addEventListener("DOMContentLoaded"... and was linking to the JS file in the head of the HTML document. The result was: some parts of another js script weren't working. I then replaced 'DOMContentLoaded' with 'load' and it started working! The weird thing now is: When I move the link to the JS file to the footer of the HTML document, then and only then it actually works with 'DOMContentLoaded'. But that's very weird isn't it? I have no idea what's going on!

问题 I would like to import the data found here: https://thecodebarbarian.wordpress.com/2014/02/14/crunching-30-years-of-nba-data-with-mongodb-aggregation/ (you can download the data towards the bottom in the Conclusion section).
