  • How to configure `lxc` like `openvz`

    - by cam
    I was going to fire up a OpenVZ node to test out some software, but it looks like OpenVZ is no longer supported in Ubuntu (deprecated in favor of lxc. It looks like can do more than simply virtualize an entire system, and I'm having trouble finding good documentation that would explain how I can start a virtualized system (using an openvz template or something). Could someone give me some pointers or direct me to some good documentation?

  • Wpf Window resizes when computer is locked.

    - by Chris
    I have a Window set to the height and width of my monitors: var r = System.Drawing.Rectangle.Union( System.Windows.Forms.Screen.AllScreens[0].Bounds, System.Windows.Forms.Screen.AllScreens[1].Bounds ); Height = r.Height; Width = r.Width; This is all fine until I Lock my computer (WIN+L), when I come back the window has resized itself to be on one monitor only. What I want to do is prevent the decrease in size, as I'm drawing on a canvas on the second monitor, and when the resize occurs, this is all lost.. Any thoughts on how I can prevent this? Cheers!

  • Creating a PHP web page that enables you to reboot the server in Linux?

    - by Stuart
    I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.

  • Using ManagementClass.Getinstances() from IronPython

    - by Leo Bontemps
    I have an IronPython script that looks for current running processes using WMI. The code looks like this: import clr clr.AddReference('System.Management') from System.Management import ManagementClass from System import Array mc = ManagementClass('Win32_Processes') procs = mc.GetInstances() That last line where I call the GetInstances() method raises the following error: Traceback (most recent call first): File "<stdin>", line 1, in <module> SystemError: Not Found I am not understanding what's not being found?!? I believe that I may need to pass an instance of ManagementOperationObserver and of EnumerationOptions to GetInstance() however, I don't understand why that is, since the method with the signature Getinstance() is available in ManagementClass.

  • Tags php improving database speed and user experience

    - by Doodle
    How did stackOverFlow, excuse me if it wasn't the first implementation of this system. Decide what its initial tags where? I want to provide users with the best experience on my site and am implementing a tags system. I don't care about search engines or any of that. I just care about my users. Does any one have any advice about things that have failed or succeeded when they allowed users to tag things? Does any one know some good resources about the methodologies of user tagging? Does any one know some good resources about implementing a tags system from a programming perspective, database structures, theories, etc ? I'll give my check to who ever I feel points me in the best direction on the subject.

  • Binding FontStyles and FontWeights to WPF ComboBox

    - by Haemoglobin
    I was just wondering if it would be possible to bind the list of available FontStyles and FontWeights to a ComboBox? For example, to bind the list of fonts to a combobox you can use: FontComboBox.ItemsSource = Fonts.SystemFontFamilies; Can I also have something for : FontStyleComboBox.ItemsSource = .... FontWeightComboBox.ItemsSource = .... ? Would it require reflection on the System.Windows.FontWeights and System.Windows.FontStyles classes or would there be an easier way than that? Thanks

  • Connection to embedded device with Windows and .Net

    - by tim
    I am building a .net application(xp, vista, 7) that will communicate with an embedded device. I will be able to connect via IP, serial port and modem. Question: Should I allow some type of open connection within my application that will allow me to connect to the device through some other channels that may be set up in the operating system just to allow future extensibility without really having to change anything on the device? I was just imagining that the operating system would be able to serve all communication channels that may be setup through the operating system to the device. Like would an admin setup some channel through SMTP or other protocol. I just didn’t want to box myself in and ignore some more open architecture. Thanks.

    If I create an app.config file in a console apps like this <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key ="key1" value ="val1"/> </appSettings> </configuration> and access the same from the console application like object sourcePath = System.Configuration.ConfigurationManager.AppSettings["key1"]; or by object sourcePath = System.Configuration.ConfigurationSettings.AppSettings["key1"]; I am able to get the value. But if I do the same thing in a class library project, I am getting a null value. Why? Where I am making mistake? I have added the proper reference System.Configuration. I am using C# 3.0

  • Where to get Google Chrome 12 for Linux i386?

    - by pts
    I need a .deb download of Google Chrome 12 (not the newest version, but version 12) for i386 Linux. Where can I get it? I need this version because my operating system doesn't have the libraries required by newer Chrome .deb packages. In this question I am not interested in upgrading or changing my operating system, and I'm not interested in using different browsers, and I'm aware of the security implications of using that particular old browser. Please give me a working download link if you know one.

  • How to exit a process run with C++ if it takes more than 5 seconds?

    - by Alex
    I'm implementing a checking system in C++. It runs executables with different tests. If the solution is not correct, it can take forever for it to finish with certain hard tests. That's why I want to limit the execution time to 5 seconds. I'm using system() function to run executables: system("./solution"); .NET has a great WaitForExit() method, what about native C++?. I'm also using Qt, so Qt-based solutions are welcome. So is there a way to limit external process' execution time to 5 seconds? Thanks

  • Wrapping a point-to-point link

    - by user3712955
    I'm using a pair of IP radios (non-WiFi) to bridge my office engineering LAN (172.0.0.0/8) to a lab in another building. The radios work fine, but they expose a web management interface I'd like to hide, and they also generate traffic (ARP, STP, and more) that I need to keep off my (very, very clean) LAN segments. I have some ARM-Linux boards (similar to Beagle/Panda/RasPi) running Ubuntu, and I've put one at each end of the link, between the radio and the LAN. Each of the boards has 2 wired Ethernet interfaces, eth0 and eth1. The LAN segments are connected to eth0, and the radios are connected to eth1. I'd like to accomplish the following: Keep radio-originated traffic off my LAN segments! Hide all services provided by the radio (web, ssh, etc.) Transparently pass all traffic between the LAN segments (including things like ARP). The above also applies to the ARM-Linux boards: No stray traffic my LAN from them either! I'd like the system to look like a switch: LAN packets arriving at one eth0 appear at the other. And neither eth0 should have an IP address: The working system should behave like a CAT6 cable with some latency (instead of ARM boards and radios). Unfortunately, I'm confused about how to properly configure the ARM Ubuntu systems. What I'm guessing I need is a bridge on each board (br0?) and a VLAN (vlan0 or eth0.0?) to isolate the LAN traffic from everything else as it passes through the ARM boards and the radios. Then I need some kind of a firewall to block sending anything out eth0 that isn't from the other eth0 (via the VLAN). I've looked at the ip and ebtables commands (especially -t broute). While the concepts sorta-kinda make sense, I'm completely lost in the details. Edit: In the perverse case that a system on one of my LAN segments has the same IP address as one of the radios, or as eth1 on the ARM-Ubuntu boards, a VLAN won't work. Which I believe means I need to tunnel all traffic between the two eth0 interfaces to get that "like a wire" behavior. Help? Finally, I'd like to have a way to temporarily expose services on the ARM boards (ssh) and the radios (web) for maintenance purposes. Ideally, it would expose an IP address with ssh available on port 22. Once connected, I figure I'd start an X11 session and run a browser on the ARM board to access the radios. Or something. I could login via the console to enable/disable this, or perhaps could use a GPIO to trigger a script. I feel I've identified most of the pieces needed to make all this happen, but I have no idea how to combine them to make a working system. Thanks!

  • Convert any object to pretty HTML in java

    - by ripper234
    How can I convert a given object (in a generic way with reflection) to pretty printable HTML? What ready made library do you recommend that does this? I need support for simple nested objects (as long as they don't create loops in the object graph). I tried to convert it to JSON, but DefaultPrettyPrinter is not HTML friendly.

  • Why can't I register a custom model binder for a List<int>?

    - by quarksoup
    I have an action that looks like public ActionResult GetUsers(List<int> userIds) {//do stuff} The list of userIds can become quite long, so I want to use Json.Net to deserialize it. To do so I created an IModelBinder implementation, which works fine for other objects, but never gets called for a List. The IModelBind looks like this public class JsonBinder : System.Web.Mvc.IModelBinder { public object BindModel(System.Web.Mvc.ControllerContext controllerContext, System.Web.Mvc.ModelBindingContext bindingContext) { //Do model binding stuff using Json.Net } } And I register this model binder with this line ModelBinders.Binders.Add(typeof(List<int>), new JsonBinder()); However the JsonBinder is never called. Why is this? Should I be using a ValueProvider?
