As I understood, the timer triggers an interrupt which in turn triggers a call to schedule . In a SMP system, I read in the book "Understanding the Linux Kernel" that "each processor runs the scheduler() function on its own". Does this mean every timer interrupt triggers every cpus to do a re-schedule at the same time? 回答1: The ARM SMP systems support two types of interrupts. SPI (shared peripheral interrupt) and PPI (peripheral private interrupts). The PPI

They should be able to be from 4 bits to 20 bits. I have never worked with bit vector before, but I guess that one would one create arrays of unsigned bytes that you manipulated using the usual AND/OR/XOR operations. The important restriction here is: I cannot rely on any libraries other than those supplied with standard Python. I think I know how I would do this in C using arrays of 8 bit unsigned bytes: e.g. to

Everything started when I integrated spring security with my application, after that all unicode values from HTML form were not encoded (spring security works correctly). I came to conclusion that this is happening probably because my DelegatingFilterProxy is called as the first filter in the chain. Here is my configuration that I thought will work, but it doesn't: 1)I'm extending AbstractSecurityWebApplicationInitializer - from javadoc: Registers the

I've made the fork correctly, I believe, but when I type this into my Mac terminal: git clone https://github.com/mygitusername/kivy.git I get this error: fatal: could not create work tree dir 'kivy.: Permission denied Anyone see what I am doing wrong?

I've tried inline, internal, and external all to no avail! I read in another SO post that since it's technically printing stuff to a file I need a print style sheet, and that didn't work either. I have a very basic page that I'm just trying to get any CSS to work with: JS: HTML: Download Maybe ? We support special element handlers . Register them with jQuery - style And finally the stylesheet that is external: h1 { color : red ; } div {

But I can't even find a reference to it in either the Rails APIs or by searching the source. Can anyone either explain to me how it works (what options you can use, etc) or point me to the place it's actually implemented so I can peruse the code on my own? 回答1: Update for Rails 4.2+ #respond_with and ::respond_to ( n.b. class method) are no longer a part of Rails . They were migrated into the third-party responders gem as of Rails 4.2 ( release notes /

There is nothing wrong with pathToFile I have verified it with curl, wget and the browser . But the problem is with jsonp() having to fetch .json files with the above structure. $http.get() can parse .json files with the above structure. But JSONP cant. It needs a dictionary at the top level and not an array. To demonstrate this, I have created this firebase: https:/

Right now, I have a config file that sits in every single one of my App servers, which could be anywhere from 4-8 at any given time. Making a config change is brutally painful to do by hand for each server. I've tried the following but to no avail: $handle = fopen('https://blah.com/config.ini', 'r'); $ini = parse_ini_file($handle, true); but I get this error: Warning: parse_ini_file() expects parameter 1 to be a valid path, resource given Is this even possible? Any
