  • Foraward Traffic from local machine to proxy server using iptables

    - by Vaibhav
    I am using Ubuntu Server 12.04. My IP is 192.168.4.160. I want to route the HTTP traffic generated locally from my system destined to a particular URL (say x.x.x.x) to pass through proxy server. My proxy server is 192.168.0.13:3128. I added following rule in iptables sudo iptables -t nat -A OUTPUT -p tcp -d x.x.x.x --dport 80 -j DNAT --to 192.168.0.13:3128 However, this rule does not seem to work for me. I captured packet in wireshark and I saw that packet is still going to x.x.x.x I am not very much familiar with iptables, so please try to be specific. Thanks in advance

  • How can I force the (re)discovery of PulseAudio network sound devices?

    - by Christian
    I'm using the PulseAudio feature of network sound devices (not Multicast/RTP) to play sound from my netbook on the audio equipment connected to the HTPC when at home. This creates a virtual sound device that I can then use instead of the physical built-in one. Most of the time this works just fine. Sometimes however, the virtual sound device just doesn't appear. Disconnecting from and reconnecting to the network helps sometimes but not always and it's annoying and potentially bad for existing TCP connections. So my question basically is: Is there some way to tell PulseAudio "Hey, just look again if you really can't find a network sound device."? Edit: Unloading and reloading the module-zeroconf-discover with pacmd does not help either and it doesn't appear to be an avahi problem per se since avahi-browse -t --all | grep PulseAudio shows lots of right-looking stuff, even when the devices aren't listed in pavucontrol or pacmd list-sinks. Edit 2: I'm using Ubuntu 12.04 on both boxes for all the difference it might make.

  • Flex Builder 3 Unclosable Editor Windows

    - by Sam Goldman
    See: http://i.imgur.com/pQNQh.png Somehow I made this happen and I don't know how to undo it. The image linked above shows my Flex Builder session. The largest section of the window is the editor. Initially, there was a blank window on the screen so I tried closing it, but I couldn't. Then I tried dragging it and realized I could drag it into a corner of itself, hence all the nested windows. I have no idea how to close these windows or simply reset the view. I went to the preferences under General Perspectives, but the "reset" button was disabled for every available perspective. Help?

  • ShellExecute not working from IDE but works otherwise.

    - by Altar
    I want to create and then open a txt file using the ShellExecute command. I have used this code for years with Delphi 7 and it worked: function Executa(CONST ExeName, Parameters: string): Boolean; begin if Parameters= '' then Result:= ShellExecute(0, 'open', PChar(ExeName), NIL , nil, SW_SHOWNORMAL)> 32 else Result:= ShellExecute(0, 'open', PChar(ExeName), PChar(Parameters), nil, SW_SHOWNORMAL)> 32; end; Now, I switch to Windows 7 (don't like it; they stuck it on my throat with my new laptop) 64 bit and the code is not working anymore when it runs from IDE. Delhi shows the CPU window with the caption "CPU-Process unknown (2352)". I close the CU windows and everything works fine until I close the application, when Delphi shows the CPU window one more time. If I run the app from outside IDE, it works fine. Looks like the debugger has something to say to me, but I don't know what.

  • NSWindowController and isWindowLoaded

    - by Jim
    Hi, I have an NSWindowController and I initialize it like this; + (MyWindowController *) sharedController { static MyWindowController *singleton = nil; if (!singleton) singleton = [[self alloc] initWithWindowNibName: @"myWindow"]; return singleton; } and I show windows like this; [[MyWindowController sharedController] showWindow: nil]; Now the problem is that I need information from some controls on that window. But I do not want to load the window if it's not yet loaded because then I can just go with the defaults. Should I use @property to access the singleton? or what is recommended here? (If @property, then please give me the readonly, nonatomic attributes too.)

  • NotifyIcon behaviour on Windows 7 with MouseClick, MouseDoubleClick events

    - by binball
    I have strange behaviour with my app after run it on Windows 7. It's connected with NotifyIcon while app is minimized. What should happens: 1) Click once on icon with mouse left button then Balloon with some text should appears 2) Double click on icon will show again app window On Windows 7 MouseDoubleClick is also fired but window is not showing. I don't know why. The same code works good on Windows XP. private void notifyIcon_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.NotifyIconShowBalloonWithData(); } } private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e) { this.Show(); WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } What did I wrong? :)

  • Javascript clears a variable after there is no further reference it

    - by Praveen Prasad
    It is said, javascript clears a variable from memory after its being referenced last. just for the sake of this question i created a JS file with only one variable; //file start //variable defined var a=["Hello"] //refenence to that variable alert(a[0]); // //file end no further reference to that variable, so i expect javascript to clear varaible 'a' Now i just ran this page and then opened firebug and ran this code alert(a[0]); Now this alerts the value of variable, If the statement "Javascript clears a variable after there is no further reference it" is true how come alert() shows its value. Is it because all variable defined in global context become properties of window object, and since even after the execution file window objects exist so does it properties.

  • Java: Line appears when using AffineTransform to scale image

    - by Malakim
    Hi, I'm having a problem with image scaling. When I use the following code to scale an image it ends up with a line either at the bottom or on the right side of the image. double scale = 1; if (scaleHeight >= scaleWidth) { scale = scaleWidth; } else { scale = scaleHeight; } AffineTransform af = new AffineTransform(); af.scale(scale, scale); AffineTransformOp operation = new AffineTransformOp(af, AffineTransformOp.TYPE_NEAREST_NEIGHBOR); BufferedImage bufferedThumb = operation.filter(img, null); The original image is here: http://tinyurl.com/yzv6r7h The scaled image: http://tinyurl.com/yk6e8ga Does anyone know why the line appears? Thanks!

  • Emacs/xterm color annoyance on Linux

    - by tgamblin
    I'm using emacs in a console window both on my local Linux box and on the login node of a remote cluster. I use emacs regularly, and I've got the foreground color set to white in my .emacs file like so: (set-foreground-color "white") (set-background-color "black") However, when I run emacs, the foreground isn't white; it's grey and very hard to read. On my Mac, emacs in a console window with the same settings shows up as proper white. But on both linux boxes, in konsole and xterm, it's grey. In case it matters, I've got TERM set to xterm-color, the desktop is running RHEL 5, and the cluster node is running RHEL 4 (CentOS). Is this some default with how Linux sets up terminal colors? How do I get white to be white? Note: this is with console emacs, not emacs under X. That's emacs -nw if you have DISPLAY set.

  • Canvas element covering the entire screen?

    - by Stefan Kendall
    I'm trying to use <canvas> in iPhone Safari, and if I place the element in the body, there are unused pixels to the left and top of the element. I tried specifying margin:0;padding:0 with CSS to no avail. What's going on here? <html> <head> $(document).ready(function() { $('#screen').attr("height", $(window).height() ); $('#screen').attr("width", $(window).width() ); //prevent scrolling $(document).bind('touchstart touchmove', function(e) { e.preventDefault(); }); }); </script> </head> <body> <canvas id = "screen"> </canvas> </body> </html>

  • Address Book is returning old values

    - by Marcus Wood
    Hi there, I am having a problem with the AddressBook framework. It all seems to be stemming from ABCopyRecordForUniqueId returning a record with old data. Example: I run up the program below in one terminal window - it shows the current data. I make a change through the address book UI - my program continues to show old data. I run up another instance of the same program in a new terminal window - it shows the updated data. I have tried posting on the omnigroup site with no luck :( so any guidance is really appreciated PS: If you would like to try the code, to get an address book ID you can export a contact as a vCard and open it with a text editor int main (int argc, const char * argv[]) { ABAddressBookRef addressBook = ABGetSharedAddressBook(); while(1) { ABRecordRef addressBookRecord = NULL; addressBookRecord = ABCopyRecordForUniqueId(addressBook, CFSTR("4064D587-0378-4DCF-A6B9-D3702F01C94C:ABPerson")); CFShow(addressBookRecord); CFRelease(addressBookRecord); sleep(1); } return 0; }

  • Display NSWindow as Subview of NSView...

    - by Nano8Blazex
    I have an NSWindow that I want to display as part of another window. It has to be an NSWindow; I don't want to change it to an NSView or anything... I just don't because it involves accessing foreign nib files and the such. How should I accomplish this if possible? I was thinking along the lines of grabbing the view of the NSWindow and sticking it as the subview of another view in my main window... but I don't think this is possible. Is it?

  • What libraries are available for manipulating super large images in .Net

    - by tpower
    I have some really large files for example 320 MB tif file with 14000 X 9000 pixels. The operations I need to perform are basically scaling the images to get smaller versions of it and breaking the image into tiles. My code works fine with small files and I use the .Net Bitmap objects but I will occasionally get Out of Memory exceptions for larger files. I've tried using the FreeImage libraries FreeImageBitmap but have the same problems. I'm using something like the following to scale the image: using (Graphics g = Graphics.FromImage((Image)result)) { g.DrawImage( source, xOffset, yOffset, source.Width * scale, source.Height * scale ); } Ideally I'd like a third party library to do all the hardwork, but if you have any tips or resources with more information I would appreciate it.

    - by jitendra
    What is preferred accessible and semantically correct method to code this type of data design? Table UL, LI DIV,SPAN For icons should i use for each place or i should is icon from CSS sprites? If we use css sprite here then how to code, and what will happen when images will be disabled ? Every link will open in new window and I have to indicate about file size also for both sighted and blind users? So what is the best method to make this design and what is best method to show icon and to indicate all type of users that file will open in new window and what is file size? Content of table should be accessible and understandable in as good as possible manner in all conditions For sighted user even if images are disabled for screen user for text browser user and if css is disabled And What is the role of Filenames of PDF, video, audio here?

  • How to notice unusual news activity

    - by ??iu
    Suppose you were able keep track of the news mentions of different entities, like say "Steve Jobs" and "Steve Ballmer". What are ways that could you tell whether the amount of mentions per entity per a given time period was unusual relative to their normal degree of frequency of appearance? I imagine that for a more popular person like Steve Jobs an increase of like 50% might be unusual (an increase of 1000 to 1500), while for a relatively unknown CEO an increase of 1000% for a given day could be possible (an increase of 2 to 200). If you didn't have a way of scaling that your unusualness index could be dominated by unheard-ofs getting their 15 minutes of fame.

  • Zookeeper naming service [closed]

    - by kolchanov
    I need a recommendation for naming service implementation. We are ISV and we have a lot of applications (services) with very different protocols such as http (Rest), low level tcp, amqp, diameter, telco protocols Rx, Ry, Ud and many others. We want to simplify configuration, deployment and service discovery procees and it seems that It's time to create central configuration registry. So I have few questions: - is zookeeper suitable for this purpose? - does exists more suitable and more special solution? - best practice for service naming for discoverin. Any standards? - recommendation for service configuration data structure Also we are keeping in mind future tasks For dynamic application distribution in a private cloud. Could you share your real life experience?

  • Where should I catch WM_HIBERNATE and WM_CLOSE in Windows Mobile/WinCE?

    - by afriza
    I have read about Windows Mobile's X button's behaviour, WM_HIBERNATE, and WM_CLOSE on Low Memory Situation. MSDN on WM_HIBERNATE: This message is sent to an application when system resources are running low. An application should attempt to release as many resources as possible when sent this message by unloading dialog boxes, destroying windows, or freeing up as much local storage as possible without changing the internal state. MSDN on WM_CLOSE: This message is sent as a signal that a window or an application should terminate. Where should I catch the message? in the main message pump? in every window? or only some windows? If I am using MFC, where should I catch it?

  • Fixed Sized Buffer or Variable Buffers with C# Sockets

    - by Keagan Ladds
    I am busy designing a TCP Server class in C# that has events and allows the user of the class to define packets that the server can send a receive by registering a class that is derived from my "GenericPacket" class. My TCPListener uses Async methods such as .BeginReceive(..); My issue is that because I am using the .BeginReceive(); I need to specify a buffer size when I call the function. This means I cant read the whole packet if one of my defined packets is too big. I have thought of creating a fixed sized Header that gets read using .BeginRead(); and the read the rest using Stream.Read(); but this will lead to the whole server having to wait for this operation to complete. I would like to know if anyone has come across this before and I would appreciate any suggestions.
