  • Programmatic resource monitoring per process in Linux

    - by tuxx
    Hi, I want to know if there is an efficient solution to monitor a process resource consumption (cpu, memory, network bandwidth) in Linux. I want to write a daemon in C++ that does this monitoring for some given PIDs. From what I know, the classic solution is to periodically read the information from /proc, but this doesn't seem the most efficient way (it involves many system calls). For example to monitor the memory usage every second for 50 processes, I have to open, read and close 50 files (that means 150 system calls) every second from /proc. Not to mention the parsing involved when reading these files. Another problem is the network bandwidth consumption: this cannot be easily computed for each process I want to monitor. The solution adopted by NetHogs involves a pretty high overhead in my opinion: it captures and analyzes every packet using libpcap, then for each packet the local port is determined and searched in /proc to find the corresponding process. Do you know if there are more efficient alternatives to these methods presented or any libraries that deal with this problems?

  • lwjgl 101: How can I write applets?

    - by Vuntic
    I have a working app in lwjgl. It doesn't do much yet; I've just started, but it does compile and run like it's supposed to. I want to make it into an applet. I've followed the guide here, and I have an applet that runs nicely and displays text and such in the applet area and can access the functions of lwjgl (like Sys.alert), but I can't figure out how to get opengl to actually render. I've tried extending an AWTGLCanvas and calling this.add(myAWTGLCanvas), where this is the Applet that I'm using, but... nothing. The initGL() and paintGL() methods never get called. I wonder if I'm supposed to be doing something with Display, but that's not for applets, right? Help? Also: This counts as a "beginner" question, right? Edit: Here's a simplified version of what I have.

  • What exactly is a property in Objective C ? What is the difference between a property ans an instance variable?

    - by tek3
    I am very much confused between instance variables and property. I have read number of posts regarding this but still i am not clear about it. I am from JAVA background and what i infer from objective C documentation is that a property is similar to JAVA BEAN CLASS (one having getter and setter of instance varibles). A property can accessed from other classes through its getter and setter methods while an instance variable is private and cannot be accessed from other classes. Am i right in thinking in this direction ?

  • ASP.NET MVC authorization & permission to use model classes

    - by Tomek
    Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

  • JSON in an AJAX request

    - by Josh K
    I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } });

  • A way to avoid deriving from the provider classes in mvc authentication

    - by Shymep
    Looking for the best practice for authentication in MVC I unfortunately didn't find the clear answer to my question. Thinking of the problem I tried to imagine some priciples that could be useful in my design. Well, I would like to use a base AccountController class I want to place all the tables such as "Users", Roles, Rights etc into my own database. But I wouldn't like to implement the standard aspnetdb design (which can be easy got by using aspnet_regsql) So the main question is can I do this without deriving abstract classes like MembershipProvider, RoleProvider etc? What I would prefer not to do is implement all the abstract methods from these classes. The second question is still about the best practice for authentication e.g. for the small projects, for the large ones?

  • MooTools Classes and JsDoc

    - by Joel Alejandro
    I have the following Moo class: Nem.Ui.Window = new Class({ Implements: [Options, Events], options: { caption: "Ventana", icon: $empty, centered: true, id: $empty, width: $empty, height: $empty, modal: false, desktop: $empty, x: $empty, y: $empty, layout: $empty }, initialize: function(options) { this.setOptions(options); /* ... */ }, setHtmlContents: function(content) { /* ... */ }, setText: function(text) { /* ... */ }, close: function(win) { /* ... */ }, /* ... */ }); I want to document it with JsDoc. I read you can use @lends [class].prototype inside new Class and mark initialize with the @constructs tag. How can I mark methods and events such? I.E.: setHtmlContents should be a method, close should be an event. Also, can the elements under options be documented, somehow?

  • Java - binary compatibility of abstract class & subclasses

    - by thSoft
    In Java, I define an abstract class with both concrete and abstract methods in it, and it has to be subclassed independently by third-party developers. Just to be sure: are there any changes I could make to the abstract class that are source compatible with their classes but not binary compatible? In other words: after they have compiled their subclasses, could I change the abstract class - apart from e.g. adding an abstract method to it or removing a protected method from it that is called by subclasses, which are of course source incompatible - in a way that could force them to recompile their subclasses?

  • count of distinct acyclic paths from A[a,b] to A[c,d]?

    - by Sorush Rabiee
    I'm writing a sokoban solver for fun and practice, it uses a simple algorithm (something like BFS with a bit of difference). now i want to estimate its running time ( O and omega). but need to know how to calculate count of acyclic paths from a vertex to another in a network. actually I want an expression that calculates count of valid paths, between two vertices of a m*n matrix of vertices. a valid path: visits each vertex 0 or one times. have no circuits for example this is a valid path: but this is not: What is needed is a method to find count of all acyclic paths between the two vertices a and b. comments on solving methods and tricks are welcomed.

  • Android Image Getter for Larger Images

    - by y ramesh rao
    I have used all the Standard Network related code for Getting Images of about 45KB to 75KB but all are failing these methods work fine for Files of about 3-5KB size of Images. How can I achieve Downloading Image of 45 - 75KB for displaying them on an ImageView in Android for my Netowrk Operations the Things I have used are final URL url = new URL(urlString); final URLConnection conn = url.openConnection(); HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(true); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); and the Second option that I have had used is:: DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet getRequest = new HttpGet(urlString); HttpResponse response = httpClient.execute(getRequest); why is this code functional for Smaller Sized Images and not for Larger Size Images. ?

  • TableAdapter to return ONLY selected columns? (VS2008)

    - by MattSlay
    (VS2008) I'm trying to configure a TableAdapter in a Typed DataSet to return only a certain subset of columns from the main schema of the table on which it is based, but it always returns the entire schema (all columns) with blank values in the columns I have omitted. The TableAdpater has the default Fill and GetData() methods that come from the wizard, which contain every column in the table, which is fine. I then added a new parameterized query method called GetActiveJobsByCustNo(CustNo), and I only included a few columns in the SQL query that I actually want to be in this table view. But, again, it returns all the columns in the master table schema, with empty values for the columns I omitted. The reason I am wanting this, is so I can just get a few columns back to use that table view with AutoGenerateColumns in an ASP.NET GridView. With it giving me back EVERY column i nthe schema, my presentation GridView contains way more columns that I want to show th user. And, I want to avoid have to declare the columns in the GridView.

  • SMS Gateway Devices

    - by u07ch
    Can anyone recommend a good SMS Gateway device that sends and receives messages and has a reasonable API. We are looking for a hardware device that a Sim Card and works with Windows / .Net. I am working with about 50 different countries (Right now 50 will only become more in the future) and dealing with that many SMS suppliers and their various methods for billing and sending / responding to messages is proving unmanageable. It may be much easier to have a single method and call it by country. We do bulk send messages but from the logs this is at most 500 messages at a time (though it could be up-to about 1500 at a time) - mostly its small numbers far less than 500 messages. Ideally would like to get message delivery data and error handling type messages back from the device. I am not interested in a hosted solution unless it has the ability to receive a message to a local number in EVERY country.

  • Authenticate sites with different domain names using the Facebook API

    - by Onema
    We have a CMS that supports multiple sites, one of our features allows our users (The site admin) to connect to the site facebook account to allow status updates, create events and upload pictures to FB from with in the CMS. The authentication needs to occur once since each site may have multiple site admins that do not have access to the site FB user name and password. We use iframe and authenticate using $facebook-require_login() which redirects the user to the FB login and authentication pages. All this works just fine but when the user hits "Allow" the authentication will break as it will only redirect to whatever is in the "Post-Authorize Redirect URL" field making the app obsolete for any other domain except the one in the "Post-Authorize Redirect URL" I know other API's authentication methods like in Vimeo and YouTube will allow you to specify a NEXT parameter which is the equivalent of the "Post-Authorize Redirect URL" and it can be set at run time. How can I make this work for multiple domain names? Any hints on this issue will be of great help

  • Choosing routing.yml based on user culture?

    - by Erland Wiencke
    In my Symfony application I would like to choose the routing.yml based on the current user's culture; 'en' => routing.en.yml 'no' => routing.no.yml and so forth. Any suggestion to how this can be done? Edit: I am not trying to do i18n this way - I use Symfony's built-in methods for that. I simply want "static" urls to reflect the user's language: /en/projects/internal/project-name /no/prosjekter/interne/prosjektnavn /fr/baguette/champs-elysee/foux-de-fafa Where "projects" is a module, the category "internal" and "project-name" are stored in the database.

  • Invoke a subclass method of an anonymous class

    - by arjacsoh
    I am trying right now to dig into anonymous classes and one question was just arised I 'd prefer not to refer to much details and to pose my question straightforward: How can I invoke the method sizzle() in the following anonymous class: public class Popcorn { public void pop() { System.out.println("popcorn"); } } class Food { Popcorn p = new Popcorn() { public void sizzle() { System.out.println("anonymous sizzling popcorn"); } public void pop() { System.out.println("anonymous popcorn"); } }; public void popIt() { p.pop(); // OK, Popcorn has a pop() method p.sizzle(); // Not Legal! Popcorn does not have sizzle() } } It is known and definite in polymorphism rules that a refernce of a superclass cannot invoke methods of subclass without downcasting (even if it refers to an object of the given subclass). However in the above case what is the "key" to invoke the sizzle() method?

  • Lazy Tables app from iphone

    - by Warrior
    I am new to iphone development. I have parsed a youtube file and displaying its contents with the image in the table view. But the scrolling has become slower because of displaying image.So i want to display the image as the lazy tables program from apple docs.Since they have used navigation based application , their rootviewcontroller loads first and then the delegate class call the parsing ,and when they reload the table view, the contents are displayed. The data array count shows 25. I am using a view controller to display the tables on the present modal view, more over when i run my application, first delegate methods call the parsing. So when i click the youtube icon in my landing page it navigates to table view. So by this time data array count shows 0. I have created table view in interface builder and set the outlets to the file owner properly. Please help me out. I want to increasing the scrolling performance. Thanks.

  • TableView - iVar reset when returning from details view

    - by iFloh
    Hi, anyone knows what I need to do to retain my TableView iVars whilst pushing a details view onto the navigation stack? I have an array and a date defined as iVars and the array is retained, whilst the date is not. I checked whether there may be an autorelease hidden somewhere but there are no obvious ones. The properties are defined as nonatomic, retain. I use custom NSDate category methods to determine specific dates at stages. These use NSDateComponents, NSRange and NSCalendar, for example: - (NSDate *)lastDayOfMonth: { NSCalendar *tmpCal = [NSCalendar currentCalendar]; NSDateComponents *tmpDateComponents = [tmpCal components:NSYearCalendarUnit | NSMonthCalendarUnit | NSEraCalendarUnit | NSWeekCalendarUnit | NSWeekdayOrdinalCalendarUnit fromDate:self]; NSRange tmpRange = [tmpCal rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:[tmpCal dateFromComponents:tmpDateComponents]]; [tmpDateComponents setDay:tmpRange.length]; [tmpDateComponents setHour:23]; [tmpDateComponents setMinute:59]; [tmpDateComponents setSecond:59]; return [[NSCalendar currentCalendar] dateFromComponents:tmpDateComponents]; } could they somehow be the reason?

  • How do I use theme preprocessor functions for my own templates?

    - by Jergason
    I have several .tpl.php files for nodes, CCK fields, and Views theming. These template files have a lot of logic in them to move things around, strip links, create new links, etc. I understand that this is bad development and not "The Drupal Way". If I understand correctly, "The Drupal Way" is to use preprocessor functions in your template.php file to manipulate variables and add new variables. A few questions about that: Is there a naming convention for creating a preprocessor function for a specific theme? For example, if I have a CCK field template called content-field-field_transmission_make_model.tpl, how would I name the preprocessor function? Can I use template preprocessor functions for node templates, CCK field templates, and Views templates? Do they have different methods of modifying template variables or adding new ones?

  • Algorithms to trim leading zeroes from a SQL field?

    - by froadie
    I just came across the interesting problem of trying to trim the leading zeroes from a non-numeric field in SQL. (Since it can contain characters, it can't just be converted to a number and then back.) This is what we ended up using: SELECT REPLACE(LTRIM(REPLACE(fieldWithLeadingZeroes,'0',' ')),' ','0') It replaces the zeroes with spaces, left trims it, and then puts the zeroes back in. I thought this was a very clever and interesting way to do it, although not so readable if you've never come across it before. Are there any clearer ways to do this? Any more efficient ways to do this? Or any other ways to do this period? I was intrigued by this problem and would be interested to see any methods of getting around it.

  • WPF/MVVM - should we create a different Class for each ViewModel ?

    - by FMFF
    I'm attempting the example from the excellent "How Do I" video for MVVM by Todd Miranda found in MSDN. I'm trying to adapt the example for my learning purpose. In the example, he has a ViewModel called EmployeeListViewModel. Now if I want to include Departments, should I create another ViewModel such as DepartmentListViewModel? The example has EmployeeRepository as the Data Source. In my case, I'm trying to use an Entity object as the datasource (Employees.edmx in Model folder and EmployeeRepository.cs in DataAccess folder). If I want to display the list of Departments, should I create a separate class called DepartmentRepository and put all department related method definitions there? What if I want to retrieve the employee name and their department's name together? Where should I place the methods for this? I'm very new to WPF and MVVM and please let me know if any of the above needs to be re-phrased. Thank you for all the help.

  • Java 1.5.0_16 corrupted colours when saving jpg image

    - by Coder
    Hi, i have a loaded image from disk (stored as a BufferedImage), which i display correctly on a JPanel but when i try to re-save this image using the command below, the image is saved in a reddish hue. ImageIO.write(image, "jpg", fileName); Note! image is a BufferedImage and fileName is a File object pointing to the filename that will be saved which end in ".jpg". I have read that there were problems with ImageIO methods in earlier JDKs but i'm not on one of those versions as far as i could find. What i am looking for is a way to fix this issue without updating the JDK, however having said that i would still like to know in what JDK this issue was fixed in (if it indeed is still a bug with the JDK i'm using). Thanks.
