  • Google images sometimes terribly slow when using dnsmasq

    - by Joril
    Hi everyone! I am the admin of a small LAN of 10+ computers. I've set up a dnsmasq server for DHCP and DNS resolution, and it's working almost fine.. My problem is that when I try to use Google images, sometimes it takes ages to show the actual images. I get just the textual part of the page (menus and so on) while the images themselves are shown as the still-loading-white boxes.. When I use the DSL router directly as DNS, the site works fine all the time. The problem sometimes presents itself with Google maps too.. The map takes ages to load. Any idea on what I could try to troubleshoot this? (dnsmasq 2.47 on CentOS 5.2 64bit, our outside connection is an asymmetrical 4Mbps DSL)

  • Howto: Configure Spring-WS to publish WSDL files with a '?WSDL' style URL?

    - by Darren
    I am trying to configure web service proxying using Mule ESB. I am attempting to do this using Mule's WSProxyService, but after stepping through the corresponding code (with the debugger), it is clear that this class replaces endpoint addresses. The problem is Spring-WS WSDL addresses are of the style http://xxxx/xxxx.wsdl, but WSProxyService expects http://xxxx/xxxx?wsdl or http://xxxx/xxxx&wsdl. It replaces the remote endpoint addresses with the local WSDL address; it cuts the remote WSDL address at the question mark i.e. '?WSDL' is intended to be chopped off, so to create the search term. But because of Spring-WS, this does not work. To break it down: WSProxyService ends up trying to use http://xxxx/xxxx.wsdl to replace http://xxxx/xxxx with http://yyyy/yyyy which fails... leading to actual web service call going direct and not through the proxy. Has anyone ever noticed/solved this problem?? Cheers, Darren

  • asp:RadioButtonList doesn't set correct selected item on load

    - by Nir
    I have this code: <asp:RadioButtonList ID="rblExpDate" runat="server" > <asp:ListItem Selected="True" Text="No expiration date"></asp:ListItem> <asp:ListItem Text="Expires on:"></asp:ListItem> </asp:RadioButtonList> that I would like to be always, on page load, to mark the first option ("no expiration date"). However, if the user marks the second option and reloads, the second option is selected, even though I do this on page load: rblExpDate.Items[0].Selected = true; rblExpDate.SelectedIndex = 0; Appreciate your help!

  • Suggestions on bug lifecycle and release management

    - by Andrew Edgecombe
    Our group is currently analysing our procedures for managing formal software releases and integrating with a bug lifecycle. What bug lifecycle model do you use? And why? For example assume a that formal releases are generated for QA once per week. At what point do you mark bugs as resolved? When the developer has committed their changes? When the changes have been reviewed and merged into the release branch? When the formal release candidate has been created? And what process, or features of your bug tracking sofware, do you use for tracking this? Are there any tips/suggestions/recommendations that you can share?

  • Coloring The Z Shell[closed]

    - by Richard
    Because I have to stare at my command prompt all the time on my computer, it should look at least half-decent, so I am trying to get it colored. The expected outcome is as seen on this site. I have the colors I want set in my .Xdefaults file, but they of course do not color my prompt. My .zshrc is Phil's Prompt. My .Xdefaults is: *background: #121212 !black xterm*color0: #353535 xterm*color8: #666666 !red xterm*color1: #AE4747 xterm*color9: #EE6363 !green xterm*color2: #556B2F xterm*color10: #9ACD32 !brown/yellow xterm*color3: #DAA520 xterm*color11: #FFC125 !blue xterm*color4: #6F99B4 xterm*color12: #7C96B0 !magenta xterm*color5: #8B7B8B xterm*color13: #D8BFD8 !cyan xterm*color6: #A7A15E xterm*color14: #F0E68C !white xterm*color7: #DDDDDD xterm*color15: #FFFFFF *foreground: #DDDDDD Help will be appreciated.

  • Slow performance by PHP directory operations on virtual machine (Ubuntu libvirt)

    - by thonixx
    Some days ago I installed an Ubuntu server and two running virtual machines with libvirt. Everything works fine except one performance problem. Everytime when I call a PHP script with directory operations the operations are very slow and not performant. Here is an example: http://zother.white-tiger.ch/ And here you see an example without a directory operation and how fast it is: http://michaeltanner.ch/ It's all on the same virtual server. The virtual machine uses 6 cores (8 are available) and 7500 megabytes RAM (8 Gigabyte are available). The disk image format is qcow2. How can I improve the performance?

  • Dependency Properties and Data Context in Silverlight 3

    - by Noam
    Hello, I am working with Silverlight 3 beta, and am having an issue. I have a page that has a user control that I worte on it. The user control has a dependency property on it. If the user control does not define a data context (hence using the parent's data context), all works well. But if the user control has its own data context, the dependency property's OnPropertyChanged method never gets called. Here is a sample: My Main Page: <UserControl x:Class="TestDepProp.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:app="clr-namespace:TestDepProp" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="100"> <Grid x:Name="LayoutRoot" Background="White"> <Border BorderBrush="Blue" BorderThickness="3" CornerRadius="3"> <StackPanel Orientation="Horizontal"> <StackPanel Orientation="Vertical"> <TextBlock Text="Enter text here:" /> <TextBox x:Name="entryBlock" Text="{Binding Data, Mode=TwoWay}"/> <Button Content="Go!" Click="Button_Click" /> <TextBlock Text="{Binding Data}" /> </StackPanel> <Border BorderBrush="Blue" BorderThickness="3" CornerRadius="3" Margin="5"> <app:TestControl PropOnControl="{Binding Data}" /> </Border> </StackPanel> </Border> </Grid> </UserControl> Main Page code: using System.Windows; using System.Windows.Controls; namespace TestDepProp { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); MainPageData data = new MainPageData(); this.DataContext = data; } private void Button_Click(object sender, RoutedEventArgs e) { int i = 1; i++; } } } Main Page's data context: using System.ComponentModel; namespace TestDepProp { public class MainPageData:INotifyPropertyChanged { string _data; public string Data { get { return _data; } set { _data = value; if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("Data")); } } public MainPageData() { Data = "Initial Value"; } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion } } Control XAML: <UserControl x:Class="TestDepProp.TestControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:app="clr-namespace:TestDepProp" > <Grid x:Name="LayoutRoot" Background="White"> <StackPanel Orientation="Vertical" Margin="10" > <TextBlock Text="This should change:" /> <TextBlock x:Name="ControlValue" Text="Not Set" /> </StackPanel> </Grid> </UserControl> Contol code: using System.Windows; using System.Windows.Controls; namespace TestDepProp { public partial class TestControl : UserControl { public TestControl() { InitializeComponent(); // Comment out next line for DP to work DataContext = new MyDataContext(); } #region PropOnControl Dependency Property public string PropOnControl { get { return (string)GetValue(PropOnControlProperty); } set { SetValue(PropOnControlProperty, value); } } public static readonly DependencyProperty PropOnControlProperty = DependencyProperty.Register("PropOnControl", typeof(string), typeof(TestControl), new PropertyMetadata(OnPropOnControlPropertyChanged)); private static void OnPropOnControlPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { TestControl _TestControl = d as TestControl; if (_TestControl != null) { _TestControl.ControlValue.Text = e.NewValue.ToString(); } } #endregion PropOnControl Dependency Property } } Control's data context: using System.ComponentModel; namespace TestDepProp { public class MyDataContext : INotifyPropertyChanged { #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion } } To try it out, type something in the text box, and hit the Go button. Comment out the data context in the controls code to see that it starts to work. Hope someone has an idea as to what is going on.

  • How to install gnome desktop from dvd on Centos 6 using command line?

    - by alwbtc
    I have installed Centos 6 to Virtualbox. Although I have chosen to install General Purpose Gnome Desktop, Gnome desktop does not start. All I get is a black and white text prompt. I would like to know how I can install Gnome Desktop from Centos dvd iso image? How do I mount the dvd image to virtual machine linux? How do I install Gnome desktop from command line? If I already have Gnome Desktop installed, why doesn't it start? How can I check from command line that I have Gnome installled? This virtual machine does not have internet connection, that's why I want to install the Gnome Desktop from dvd. Best Regards

  • Code Igniter email protocols and rendering HTML emails?

    - by John
    I have a website built in code igniter that emails users. I use CI's email class from the controller to do mail out, but I discovered that if I use the "mail" protocol, some (not all) users see un-rendered html emails with the html mark up viewable, while others do not. But if I use the "sendmail" protocol, all users get rendered html emails. So if I did this $config['protocol'] = 'mail'; // add a few more config entries $this->email->initialize($config); Not everyone sees html emails If I did this $config['protocol'] = 'sendmail'; // add a few more config entries $this->email->initialize($config); Everyone sees html emails Why does the protocol matter? Are the email headers different between the two?

  • SSH tunnel over http proxy with blocked 443 (SSL)

    - by Evgeny Zhulenev
    Is it possible to create an SSH tunnel over http-proxy when https access is denied? I had such configuration in .ssh\config Host home User root Hostname *my-home-pc-with-ssh-access-allowed* Port 8090 ProxyCommand corkscrew db-isa-01 8080 %h %p ~/.ssh/.corkscrew-db-isa-auth IdentityFile ~/.ssh/id_rsa Where db-isa-01 is my corporate proxy server. Today the admins blocked all https access and allowed it only for few servers on the white list. I used this command to create a tunnel: ssh -D 7070 -o 'GatewayPorts yes' -A -q -g -t root@home and now it doesn't work. As I can understand, that's because our proxy denies all https connections Proxy could not open connnection to ***: Proxy Error ( The specified Secure Sockets Layer (SSL) port is not allowed. Forefront TMG is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. ) P.S. I use Windows 7, and corscskrew with cygwin, so Linux solutions not suitable for me.

  • problem with monitor

    - by misha nesterenko
    I have an Asus VB191T connected to notebook via DVI connector as secondary monitor. I am observing some problems on that monitor. Photo of a properly functioning screen: Photo of my Asus VB191T screen: So as you can see there are white lines on both sides of black ones. Resolution is set to the monitor's native resolution which is 1280x1024. The artifacts don't appear for every color, and they show up the clearest where there is black on a grey background. What could be wrong? The monitor itself? Perhaps the connector?

  • Repairing malformatted html attributes using c#

    - by jhoefnagels
    I have a web application with an upload functionality for HTML files generated by chess software to be able to include a javascript player that reproduces a chess game. I do not like to load the uploaded files in a frame so I reconstruct the HTML and javascript generated by the software by parsing the dynamic parts of the file. The problem with the HTML is that all attributes values are surrounded with an apostrophe instead of a quotation mark. I am looking for a way to fix this using a library or a regex replace using c#. The html looks like this: <DIV class='pgb'><TABLE class='pgbb' CELLSPACING='0' CELLPADDING='0'><TR><TD> and I would transform it into: <DIV class="pgb"><TABLE class="pgbb" CELLSPACING="0" CELLPADDING="0"><TR><TD>

  • How can I style the command being entered in a bash prompt?

    - by C4H5As
    While watching this intro video to Brunch, at about t=1:30 the command prompt being used has some very cool styles. The part I'm interested in is how the presenter managed to colour the text being entered on the prompt, while it's being entered. It looks like the first argument is coloured green when it becomes a valid executable command & purple when it's invalid. Successive arguments appear white, though it looks like a valid file path gets an underline (see ~ t=2:01). What's the trick here? Is this a custom terminal emulator? Is it some kind of magic $PS1?

  • jQuery/AJAX type-ahead/auto-complete

    - by Prasad
    I have read several articles/questions/forums discussing the best auto-complete plugin for jQuery. After trying several good ones, I've realized a flaw in most. If you are looking up countries and type 'In', a couple of countries show up. If you continue typing I-n-d-i-a, this results in 5 AJAX calls (see http://www.freeimagehosting.net/uploads/6f1bcd69e1.png) its quite natural that India is a subset of In, so why call again? We need to simply filter the retrieved list client-side. Anyone knows about such an implementation? What is the status of the Jquery Autocomplete feature? I read at StackOverflow that it is no longer available with Jquery; but the Jquery website has a 'New' mark besides the link to Autocomplete. Thanks

  • Any way to remove IEs black border around submit button in active forms?

    - by Magnar
    I am implementing a design that uses custom styled submit-buttons. They are quite simply light grey buttons with a slightly darker outer border: input.button { background: #eee; border: 1px solid #ccc; } This looks just right in Firefox, Safari and Opera. The problem is with Internet Explorer, both 6 and 7. Since the form is the first one on the page, it's counted as the main form - and thus active from the get go. The first submit button in the active form receives a solid black border in IE, to mark it as the main action. If I turn off borders, then the black extra border in IE goes away too. I am looking for a way to keep my normal borders, but remove the outline.

  • Emacs Column based Narrowing or Folding

    - by froit
    Is there column based narrowing in emacs. I tend narrow in one everything between script tags but that still keeps the original indent (space before var). It would be great if I could actually column narrow to the the beginning of the indent since otherwise the electrict indent tries to bring it to column 0. var foo = 1; var bar = 2; Alternate solution could be to mark the starting indents as uneditable, but I am also not sure how to do this. P.S. I am aware of MMM and NXHTML and html-helper-modes, but I am not looking to use them due to complexities.

  • PDF problems with Evince on Ubuntu

    - by ILMV
    One of my collegues is trying to print a PDF that our designer has sent him, created using Adobe InDesign CS4 (6.0.4). When he opens it up using Evince (version 2.28 on Ubuntu 9.10 thin client) it displays exactly how we expect it to, however when he prints it's not rendering correctly, for example: Missing one logo, the other dozen display perfectly Missing a white box with 30% opacity (without this the blue text sits on a light blue background) The dotted border of a box is screwed up (missing dots in the corners, but fine on the straights) Finally the font quality is slightly poorer than a print out we've done on a working machine. I have tried it on my Ubuntu dev box (Evince version 2.22 on Ubuntu 8.04 server) and it displays and prints perfectly. Can anyone offer an explanation as to why this might be happening, I find it hard to understand how an older version of Evince is displaying it better than a newer version. Thanks! EDIT Just for anyone surfing in, it's likely yo be a CUPS problem on our server, cheers ;-)

  • Abstract base class for Winforms-Control and VS2008 Designer support?

    - by BeowulfOF
    Hi, I engadged a problem with inherited Controls in WinForms, and need some advice on it. I do use a base class for items in a List (selfmade GUI list made of a panel) and some inherited controls that are for each type of data that could be added to the list. There was no problem with it, but I know found out, that it would be right, to make the base-control an abstract class, since it has methods, that need to be implemented in all inherited controls, called from the code inside the base-control, but must not and can not be implemented in the base class. When I mark the base-control as abstract, the VS2008 Designer refuses to load the window. Is there any way to get the Designer work with the base-control made abstract?

    I'm building an interface for marking dates on a calendar as being booked. The user 'paints' on the dates they want to mark as booked. here's how it looks: here are the functions: function load_red_paint(){ $('td').bind('mousedown', function(){ $(this).addClass('booked'); $('td').bind('mouseenter', function(){ $(this).addClass('booked'); }); unbind_brush(); }) } function unbind_brush(){ $('td').bind('mouseup', function(){ $('td').unbind('mouseenter'); }); $('table').bind('mouseleave', function(){ $('td').unbind('mouseenter'); }); } the problem: My unbind_brush() function works great except for if the user mouseup's outside of the calendar, i tried to fix this my also unbinding on mouseleave of that calendar with this bit: $('table').bind('mouseleave', function(){ $('td').unbind('mouseenter'); }); but with no joy, am i missing something obvious?!!!

  • Where to learn how to replicate an Excel template?

    - by Rosarch
    This Excel template is really cool. There are a lot of things in it I don't know how to do, such as: Having header rows that "stick" to the top even when you scroll down Slider on the first page changes where the chart pulls its data from Functions seem to be referring to named ranges in tables, like =SUM([nov]). Where do those names come from? Clicking "back to overview" on the "Budget" page returns you to the "Dashboard" page The number under "starting balance" of the top right corner of "Budget" changes when you change cell C5 On "Budget", each cell in the first column of each table has a drop-down menu for text, which seems to come from the "Setup" page The background isn't just plain white, but when I try to format paint it onto a new sheet, nothing happens If you know how any of these effects are achieved, I'm definitely curious. But I guess the main point of my question is where I can go to answer these questions for myself. Are templates explained anywhere?

  • Asp.net mvc, view with multiple updatable parts - how?

    - by DerDres
    I have started doing asp.net mvc programming and like it more everyday. Most of the examples I have seen use separate views for viewing and editing details of a specific entity. E.g. - table of music albums linking to separate 'detail' and 'update' views [Action] | Title | Artist detail, update | Uuuh Baby | Barry White detail, update | Mr Mojo | Barry White With mvc how can I achieve a design where the R and the U (CRUD) are represented in a single view, and furthermore where the user can edit separate parts of the view, thus limiting the amount of data the user can edit before saving? Example mockup - editing album detials: I have achieved such a design with ajax calls, but Im curious how to do this without ajax. Parts of my own take on this can be seen below. I use a flag (enum EditCode) indicating which part of the view, if any, that has to render a form. Is such a design in accordance with the framework, could it be done more elegantly? AlbumController public class AlbumController : Controller { public ActionResult Index() { var albumDetails = from ManageVM in state.AlbumState.ToList() select ManageVM.Value.Detail; return View(albumDetails); } public ActionResult Manage(int albumId, EditCode editCode) { (state.AlbumState[albumId] as ManageVM).EditCode = (EditCode)editCode; ViewData["albumId"] = albumId; return View(state.AlbumState[albumId]); } [HttpGet] public ActionResult Edit(int albumId, EditCode editCode) { return RedirectToAction("Manage", new { albumId = albumId, editCode = editCode }); } // edit album details [HttpPost] public ActionResult EditDetail(int albumId, Detail details) { (state.AlbumState[albumId] as ManageVM).Detail = details; return RedirectToAction("Manage", new { albumId = albumId, editCode = EditCode.NoEdit });// zero being standard } // edit album thought [HttpPost] public ActionResult EditThoughts(int albumId, List<Thought> thoughts) { (state.AlbumState[albumId] as ManageVM).Thoughts = thoughts; return RedirectToAction("Manage", new { albumId = albumId, editCode = EditCode.NoEdit });// zero being standard } Flag - EditCode public enum EditCode { NoEdit, Details, Genres, Thoughts } Mangae view <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication1.Controllers.ManageVM>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Manage </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Manage</h2> <% if(Model.EditCode == MvcApplication1.Controllers.EditCode.Details) {%> <% Html.RenderPartial("_EditDetails", Model.Detail); %> <% }else{%> <% Html.RenderPartial("_ShowDetails", Model.Detail); %> <% } %> <hr /> <% if(Model.EditCode == MvcApplication1.Controllers.EditCode.Thoughts) {%> <% Html.RenderPartial("_EditThoughts", Model.Thoughts); %> <% }else{%> <% Html.RenderPartial("_ShowThoughts", Model.Thoughts); %> <% } %>

  • Need help generating a core dump from apache segfault

    - by blockhead
    I have a script which intermittently returns a white screen of death in firefox and Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. chrome. When I try to access the script using a PHP HTTP client (like Zend_Http_Client), intermittently I get an exception (sorry I don't have the exact message on me at the moment). I suspect a segfault. This is further buttressed by the lines in my error log that look like this: [Thu Mar 18 16:03:02 2010] [notice] child pid 845 exit signal Segmentation fault (11) Now, I'm running RedHat, and I know that RedHat doesn't generate core dumps out-of-the-box. I followed the instructions here http://kbase.redhat.com/faq/docs/DOC-5353, but I'm not seeing any core dumps. How do I generate a core dump?
