  • Why does '~$ nc -z T43 1-1024' not produce any output although '~$ ping T43' is successful?

    - by user43816
    Why does '~$ nc -z T43 1-1024' not produce any output although '~$ ping T43' is successful? '~$ nc -z -v T43 1-1024' prints 'Connection to T43 22 port [tcp/ssh] succeeded!' and 'nc: connect to T43 port 1000 (tcp) failed: Connection refused.' 'man nc': "PORT SCANNING: It may be useful to know which ports are open and running services on a target machine. The -z flag can be used to tell nc to report open ports, rather than initiate a connection. For example: '$ nc -z host.example.com 20-30'.

  • accessing my public methods from within my namespace

    - by Derek Adair
    I am in the process of making my own namespace in JavaScript... (function(window){ (function(){ var myNamespace = { somePublicMethod: function(){ }, anotherPublicMethod: function(){ } } return (window.myNamespace = window.my = myNamespace) }()); })(window); I'm new to these kinds of advanced JavaScript techniques and i'm trying to figure out the best way to call public methods from within my namespace. It appears that within my public methods this is being set to myNamespace. Should I call public methods like... AnotherPublicMethod: function(){ this.somePublicMethod() } or... AnotherPublicMethod: function(){ my.somePublicMethod(); } is there any difference?

  • tiled images in swing

    - by sasquatch90
    I have task to prepare two windows with swing. One contains grid of squares, with random numbers in them. In second I need to load pieces of tiled image and then show them in the correct order, forming tiled image. Windows should look like this : http://img535.imageshack.us/img535/3129/lab8a.jpg Okay so how to bite this ? I've used swing only few times to draw some 2d polylines, so basically I just theoretically now what to do. Ok, so window number 1: I start with creating Jframe for the window. Then I do for loop and in it create 16 JLabels with random numbers in them ? How to set margins between each tile and the whole window ? Window number 2 : So I start the same, but instead of loading numbers I add images ? Now, how can I load image from file and then set it as background ?

  • Need to override cascade style

    - by WillingLearner
    i have a style : .window .div { border:medium solid #000000; height:150px; background-color: #0099FF; } and then i have another style: #NewDiv { font:Arial, Helvetica, sans-serif; font-size: 24px; height: 20px; border-bottom-width: medium; border-bottom-style: solid; border-bottom-color: #000000; } I need to put a #NewDiv div tag inside of window .div, BUT... #NewDiv must retain its own styling while sitting inside of window .div div tags. How do I do this? Currently when I try, #NewDiv takes on the same styling as window .div when i place it inside of it and i dont want that at all. Any suggestions?

  • How can two programs talk to each other in Java?

    - by Arnon
    I want to ?reduce? the CPU usage/ROM usage/RAM usage - generally?, all system resources that my app uses - who doesn't? :) For this reason I want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which means it should call the update method (that i wrote) that found in the Main class. How can I call the update method in the Main program from the preferences program? To put it another way, is a way to build preferences window that take system resources just when the window appears? Is this approach - of separating programs and let them talk to each other (somehow) - the right approach for speeding up my programs?

  • iptables firewall to protect against automated entries

    - by Kenyana
    I am getting unusually large calls on my app. I have implemented CSRF Check over ajax and its working but am still getting so many calls. My guess is that someone has a script that is 'logged' in and making all these calls. Could someone please share a good iptables script for blocking ip's that run 10 calls to /controler/action in a second. I am using `/sbin/iptables -A INPUT -p tcp --syn --dport $port -m connlimit --connlimit-above N -j REJECT --reject-with tcp-reset save the changes see iptables-save man page, the following is redhat and friends specific command service iptables save` That is from cyberciti

  • long startup time...Need help

    - by Jeff
    My app is all done and working great. So now I ran it on a old iPhone and the app takes 17.3 seconds to start!?!? i spent a lot of time looking into it and i found that the reason it is taking so long to load is i have a lot of views and each view has a png background image. All my views and made in IB and in my code: #import "MyTestAppDelegate.h" #import "MyTestViewController.h" @implementation MyTestAppDelegate @synthesize window; @synthesize viewController; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end At the end of the code where is says: [window addSubview:viewController.view]; the app seems to be loading all the views in the nib at the same time. All the png's from all the views are about 12mb. There is no need for the app to load all the views at the same time during startup. Is there a way i can only load the first "home" view at startup? (All the views are part of the same nib.)

  • Can I modify the way Windows draws the Aero UI?

    - by LonelyPixel
    Windows 7 with Aero Glass basically looks quite nice I think. But it has some major drawbacks regarding readability: I cannot easily tell whether a window is currently active or not. I've been tweaking the colours and transparency levels a lot recently but the only safe indicator is the close button: it's red when the window is active, it's colourless otherwise. Then there's the window title text. It is always painted black, on however dark a background. Again, regardless of whether the window is active or not. I've seen WindowBlinds and the tons of available themes you can use with it. Browsing through the most popular or highest rated in several categories I was really scared. I don't want to face Terminator every day, feel like in the Jungle or be fooled that I had an Apple computer which I do not. All I want to change is to make a greater colour difference between active and inactive windows and to invert the window title text colour for dark backgrounds. (Including that visibility hack of a spray brush background.) Is there some Windows API to alter the way Windows draws its windows or does it take the years of private research from Stardock to hook into that? I mean they say it's approved by Microsoft, so I assume there's some official documentation for that, I just couldn't find any.

  • xaml shapes - relative to canvas size

    - by taglius
    I have the need to draw shapes in XAML that are always relative to the container window/canvas size. For example, I need a window to show a 3x3 grid on it, where the grid always splits the window into 3 equal parts. Can I create lines that are bound to 1/3 the width of the grid? thank you

  • Is there a transformation matrix that can scale the x and/or y axis logarithmically?

    - by Dave M
    I'm using .net WPF geometry classes to graph waveforms. I've been using the matrix transformations to convert from the screen coordinate space to my coordinate space for the waveform. Everything works great and it's really simple to keep track of my window and scaling, etc. I can even use the inverse transform to calculate the mouse position in terms of the coordinate space. I use the built in Scaling and Translation classes and then a custom matrix to do the y-axis flipping (there's not a prefab matrix for flipping). I want to be able to graph these waveforms on a log scale as well (either x axis or y axis or both), but I'm not sure if this is even possible to do with a matrix transformation. Does anyone know if this is possible, and if it is, what is the matrix?

  • What is the proper way to wait a script loaded completely before another

    - by FatDogMark
    I am making a website that is divided by several sections <div id='section-1' class='section'>web content</div> <div id='section-2' class='section'>web content</div> I have like ten sections on my webpage ,each sections height is set to the user window height when document is ready by javascript $('.section').height($(window).height()); Some effects like slideshows on my webpage require the calculated height of the section in order to work properly. Therefore I always use something like this at document ready as a solution. setTimeout(startslideshow,1000); setTimeout(startanimations,1000); ...etc To make sure the section height is the user window height before the slideshow's code start because the sections cannot change to user window height instantly once the webpage loaded will generate serious problems in my slideshow code,like wrong calculated positions. Therefore there will be a situation that's after the page loaded, there will be about a second everything is messed up,before everything can works properly, how could I avoid that being seen by the user? I tried to $(document).hide(),or $('html,body').hide(), then fade in after a second,but I get other weird problems, especially on ipad,my fixed position top navigation bar will always become 'not fixed' while user is scrolling. As I am a self-learner, I afraid my method is not typical. I want to know what is the common ways of real web programmers usually do when they have to divide his webpage into different sections and set its height to window height , then make sure the other effects that's depends on the section height works properly and avoid to wait the height change for a second?

  • How to tell an iphone app user what will happen before opening Facebook login dialogue

    - by docno
    Apps that allow users to log in over a 3rd party authentication provider (e.g. Facebook, Google, Twoitter,...) should open a browser window to let the user authenticate against the provider. That means, at some point, an app is backgrounded and the user interacts with a browser window. Just before the browser opens, it's a recommended pratctice to inform the user about what will happen (see e.g. Getting Started with OAuth 2.0 - O'Reilly), let's say an alert window with something like "you will leave now the XYZ app and a browser window will open where you can enter your credentials safely". My question: How can that be done if I use the facebook SDK for ios? Looking at the SDK, there seem to be no notifications and no designated states that would allow me to detect that the sdk is about to background my app and about to opening either Safari or the Facebook app.

  • How can I close a JFrame by click on a button?

    - by Roman
    I would like to have a button in my window such that if I click it (button) the window is closed. I found out that I can close a window in the following way: referenceToTheFrame.hide(); //hides the frame from view refToTheFrame.dispose(); //disposes the frame from memory But if I do this way, compiler complains: Note: myProgram.java uses or overrides a deprecated API Note: Recompile with -Xlint:deprication for details. Do I do something unsafe?

  • Check for element equality in an animation function.

    - by Zardoz
    I have the the below code and would expect that in the first pass of the fadeTo function "yes" would be printed as those first two console logs tell me it is the same element. But it doesn't recognize them as equal. What do I miss here? var tds = self.element.find("td:nth-child(" + (columnIndex + 1) + ")"); tds.fadeTo(options.columnFadeOutTime, 0, function() { window.console.log(tds.first()); window.console.log($(this)); if ($(this) == tds.first()) { window.console.log("yes"); } else { window.console.log("no"); } }

  • Endless scroll paging in jquery Safari

    - by socheata
    I'm using : $(window).scroll(function () { if ($(window).scrollTop() + 10 >= ($(document).height() - $(window).height())) { loadContent(); } } It works fine with Chrome, IE, Firefox but except in Safari. In function loadContent, I used JSON to load data, as this tutorial. But while I test in Safari, It takes the content twice from JSON. If the other takes 9 items, then Safari takes 18 items. Does anyone know how to solve this problem? Thanks.

  • Qt - 2 QMainWindow glued - Size of Layout

    - by user1773603
    I have a main window that I center this way in main.cpp : int main(int argc, char *argv[]) { QApplication app(argc, argv); QMainWindow *qmain = new QMainWindow; Ui_MainWindow ui; ui.setupUi(qmain); QRect r = qmain->geometry(); r.moveCenter(QApplication::desktop()->availableGeometry().center()); qmain->setGeometry(r); qmain->show(); return app.exec(); } In this "qmain" main window, I can create another QMainWindow and I try to make stick (or glue I don't know how to say) the two windows. Actually, I would like the right-top corner of the first one to be located at the left-top of the second one. For this, I use the following Ui_MainWindow's member function : void Ui_MainWindow::generate_IC() { qmenu = new QMainWindow; DiskMenu = new Ui_DiskGalMenu; DiskMenu->setupUi(qmenu); setInitialDiskMenuPosition(qmenu, this); qmenu->show(); } and the setInitialDiskMenuPosition : void Ui_MainWindow::setInitialDiskMenuPosition(QMainWindow *MainWindow, Ui_MainWindow *parent) { QSize size = parent->widget->size(); QDesktopWidget* desktop = QApplication::desktop(); int width = desktop->width(); int height = desktop->height(); int mw = size.width(); int mh = size.height(); int right = (width/2) + (mw/2); int top = (height/2) - (mh/2); MainWindow->move(right, top); } But the problem is that I don't get exactly what I want since the centralwidget size "parent- widget-size()" only returns the size of the widget and not the whole "qmain" parent window. So I have a light shift because the borders of the "qmain" window are not taken in account like it is shown below : If I could have access to the size of the whole parent window... If anyone could help me

  • What is this effect called?

    - by Majid
    Hi all, I have seen links that open modal windows AND have a nice animation effect that create the illusion that the window grows out of the link clicked. On closing the window a similar animation shows that the window shrinks and disappears in the link which originally opened it. I remember I saw it on some jquery page but don't remember where and don't know what this effect is called. Have you seen this? Examples?

  • More than one JPanel in a Frame / having a brackground Image and another Layer with Components on the top
