  • MacPorts / Terminal: `Unrecognized action "sudo"`

    - by Chris
    I'm trying to install Image Magick on MAMP. And I'm seriously out of my depth. I've installed MacPorts, and opened the terminal. I've typed in sudo port -v selfupdate per the instructions on http://www.macports.org/install.php#pkg But the response I get from the Terminal is Unrecognized action "sudo" I've googled and googled, but can't find anything that makes a slab of sense. Any clever people feeling generous?

  • How to add a background to text only ?

    - by misha-moroshko
    I have a background image on top of which there is some text. It is very hard to read the text because of the background. I would like to add a white background just around the text itself, such that the text could be easily read. How can I accomplish this using CSS/Javascript/jQuery ?

  • session fixation

    - by markiv
    Hi All, I am new to web development, and trying to get a hold on security issues. I went through this article on http://guides.rubyonrails.org/security.html these are some of the steps the author has mentioned how an attacker fixes session. 1. The attacker creates a valid session id: He loads the login page of the web application where he wants to fix the session, and takes the session id in the cookie from the response (see number 1 and 2 in the image). 2. He possibly maintains the session. Expiring sessions, for example every 20 minutes, greatly reduces the time-frame for attack. Therefore he accesses the web application from time to time in order to keep the session alive. 3. Now the attacker will force the user’s browser into using this session id (see number 3 in the image). As you may not change a cookie of another domain (because of the same origin policy), the attacker has to run a JavaScript from the domain of the target web application. Injecting the JavaScript code into the application by XSS accomplishes this attack. Here is an example: <script>?document.cookie="_session_id=16d5b78abb28e3d6206b60f22a03c8d9";?</script>. Read more about XSS and injection later on. 4. The attacker lures the victim to the infected page with the JavaScript code. By viewing the page, the victim’s browser will change the session id to the trap session id. 5. As the new trap session is unused, the web application will require the user to authenticate. 6. From now on, the victim and the attacker will co-use the web application with the same session: The session became valid and the victim didn’t notice the attack. I dont understand couple of points. i) why is user made to login in step5, since session is sent through. ii) I saw possible solutions on wiki, like user properties check and others why cant we just reset the session for the user whoever is login in when they enter username and password in step5? Thanks in advance Markiv

  • Repositioning a label with mouseevents to anywhere on the screen

    - by user2947295
    I've created a label and used setPixmap to attach a .png image to the label. I've also setWindowFlags to disable the title bar and create a frameless window. Because I've disabled those, it also disables the ability to drag anything around, so I want to create mouseevents (unless there's a better method) to position my label anywhere on the screen exactly like dragging the frame of a window. How would I do that? An example and brief explanation would be greatly appreciated.

  • Localization of icon and default screen in iPhone

    - by hgpc
    Can the app icon and default screen be localized in iPhone? Has anyone tried it? In theory it should be possible as they're just image resources, but I found no explicit mention of this in the documentation, and I wouldn't like to have my app rejected or failing for this.

  • encode video is reverse?

    - by bob
    Hi, Does anyone know if it is possible to encode a video using ffmpeg in reverse? (So the resulting video plays in reverse?) I think I can by generating images for each frame (so a folder of images labelled 1.jpg, 2.jpg etc), then write a script to change the image names, and then re-encode the ivdeo from these files. Does anyone know of a quicker way? This is an FLV video. Thank you

  • How to Block images (img tags) from an iFrame?

    - by ramayac
    Hello, Im searching for ideas to solve the following problem: I'm loading an URL (any for that matter) into an iFrame, and then block (server side) all image tags, o object tags before sending the page to the client. -- What I was thinking to do is: fetching the URL, and then manipulating the fetched content using a Java library (any recomendation on that matter?). And after that, send the modify content to que client. Would that be the best approach to solve this problem? suggestions are wellcome :)

  • How to check in which position (landscape or portrait) os the iPhone now?

    - by Knodel
    I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { //Code } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) { //Code } } The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?
