  • What has bigger priority: opacity or z-index in browsers?

    - by MartyIX
    Hi, I'm coding a "popup window" in javascript and I've come across an interesting thing: http://img91.imageshack.us/img91/4761/error01cropped.png - the navy square under the popup window is visible even though I would expect it to be hidden. The popup was added after the square so it should be on the top. CSS opacity property of the navy square is 0.3 (from what I've tried it seems that every number from the interval (0,1) would yield the same result) if I change it to 1 then it behaves as expected (i.e. the part of the square under the popup is hidden). I've tried to use z-index property and set 10 for square and 100 for the popup but it doesn't change anything. What am I missing? Why is the part of square displayed? Thanks for help!

  • Can't load any applications

    - by oshirowanen
    After installing Eclipse, I wanted to try to enable the global unity menu for Eclipse. Following a guide on the web, I was to make a change to: sudo nano /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so by changing Eclipse to Xclipse. After making that change, and then running sudo ldconfig. and even restarting, I can no longer open any application. I just see the application appear on the screen for a split second and then it disappears. So far I have noticed that I can no longer load Eclipse and Chrome. Anyone know how to fix this? I have tried changing Xclipse back to Eclipse and running the command sudo ldconfig, but it makes no difference.

  • Oculus Rift with Antichamber

    - by Scott Hainline
    Antichamber runs great on linux (steam version). But it is not playable with the Oculus Rift at this point. The issues are: 1) no headtracking 2) graphics are not being split and distorted by Oculus SDK My current plan is to use LD_PRELOAD to add the functionality, this seems to be the linux equivalent of DLL injection. Antichamber appears to be using SDL, I'm hoping this can be configured to use the headtracking data as a joystick and apply the graphics distortion, but I am not sure which functions I should be looking for. Is there a simpler way of getting these issues resolved? Is SDL the right choice here? Would appreciate any information on how the Unreal Engine 3 works under linux; and library injection too.

  • Switching songs - MediaPlayer lags the game

    - by Fibericon
    When the player encounters a boss in the game I'm working on, I want to have the music change. It seems simple enough with the MediaPlayer class to fade out the current song, switch to another, and then fade the new song in. However, at the point where the second song starts, the game freezes for a split second. The songs in question aren't particularly large either - the first song is 1.7mb and the second song is 3.1mb, both mp3 format. This is the code I'm using to do it: protected void switchSong(GameTime gameTime) { if (!bossSongPlaying) { MediaPlayer.Volume -= ((float)gameTime.ElapsedGameTime.TotalSeconds/10); if (MediaPlayer.Volume < 0.05f) { MediaPlayer.Play(bossSong); MediaPlayer.Volume = 1.0f; bossSongPlaying = true; } } } What can I do to eliminate that momentary hang?

  • How to push oath token to LocalStorage or LocalSession and listen to the Storage Event? (SoundCloud Php/JS bug workaround)

    - by afxjzs
    This references this issue: Javascript SDK connect() function not working in chrome I asked for more information on how to resolve with localstorage and was asked to create a new topic. The answer was "A workaround is instead of using window.opener, push the oauth token into LocalStorage or SessionStorage and have the opener window listen to the Storage event." but i have no idea how to do that. It seems really simple, but i don't know where to start. I couldn't find an relevant examples. thanks for your help!

  • Enable Configurator for Return Orders

    - by ChristineS-Oracle
    With release 12.2.4 for non-referenced RMAs, Order Management will allow you to configure the model from Sales Order / Quick Sales Order windows. This is only allowable when profile  OM: Enable Configuration UI for RMA is set to Yes.  All selected options must be returnable, as well as all included items. Order Management explodes included items and creates options and option classes in a way similar to outbound orders. The application creates all selected components with same line number but different option/component number.  Additionally, the application does not allow re-configuration and/or deletion of any line if any line in the same configuration is received, fulfilled, closed, cancelled, or split. For additional information refer to the Oracle Order Management Release Notes for Release 12.2.4 (Doc ID 1906521.1).

  • JFrame.setBackground() not working -- why?

    - by devoured elysium
    JFrame mainFrame = new JFrame(); mainFrame.setSize(100, 100); mainFrame.setBackground(Color.CYAN); mainFrame.setVisible(true); My intent is to create a window with a cyan background. What is wrong with this? My window doesn't get cyan, as I'd expect! Also, could anyone point out why I seem to have all the colors in duplicate (there's a Color.CYAN and a Color.cyan). Is there any difference at all between the two? Maybe the older one was a constant from before there were enums in Java and the second one is from the Enum? Thanks

  • Exposing classes inside modules within a Python package directly in the package's namespace

    - by Richard Waite
    I have a wxPython application with the various GUI classes in their own modules in a package called gui. With this setup, importing the main window would be done as follows: from gui.mainwindow import MainWindow This looked messy to me so I changed the __init__.py file for the gui package to import the class directly into the package namespace: from mainwindow import MainWindow This allows me to import the main window like this: from gui import MainWindow This looks better to me aesthetically and I think it also more closely represents what I'm doing (importing the MainWindow class from the gui "namespace"). The reason I made the gui package was to keep all the GUI stuff together. I could have just as easily made a single gui module and stuffed all the GUI classes in it, but I think that would have been unmanageable. The package now appears to work like a module, but allows me to separate the classes into their own modules (along with helper functions, etc.). This whole thing strikes me as somewhat petty, I just thought I'd throw it out there to see what others think about the idea.

  • System that splits passwords across two servers

    - by Burning the Codeigniter
    I stumbled upon this news article on BBC, RSA splits passwords in two to foil hackers' attacks tl;dr - a (randomized) password is split in half and is stored across two separate servers, to foil hackers that gained access to either server upon a security breach. Now the main question is, how would this kind of system would be made... codespeaking, for PHP which I commonly develop on my web applications, the database password is normally stored in a configuration file, i.e. config.php with the username and password, in that case it is understandable that the passwords can be stolen if the security was compromised. However when splitting and sending the other half to the other server, how would this go on when making a communication to the other server (keeping in mind with PHP) since the other server password would be stored in a configuration file, wouldn't it? In terms of security is to keep the other server password away from the main one, just exactly how would the main server communicate, without exposing any other password, apart from the first server. This certainly makes me think...

  • How to implement a Google-chrome-like title bar for Java SWT application

    - by MartyC
    I have inherited development of a Java/SWT application running on Windows only. One of the feature requests that I need to scope is a Google-chrome-type title bar in place of the SWT windows title bar. The application's tabs appear at the same level as the window control buttons. My understanding is that I will need to: write a Windows widget capable of rendering the custom look and managing tabs as opposed to menus. expose the Windows widget as a dll for use in Java via JNI write a custom SWT widget to wrap it and expose the tab management interface. I have a lot of experience with Java programming, GUI programming with Swing/AWT, and non-GUI C# programming. Windows GUI programming and SWT are new to me so I'm not sure where to start. The best I have found so far is a 2001 article on writing your own SWT widget. My biggest unknown is the best way to implement a custom Windows application-window.

  • UIScrollView Does not Scroll

    - by paul simmons
    I have added a long info screen to my iPhone app. The info is a long UIImageView, and it is contained inside a UIScrollView. They are both defined in .xib file. At run-time, initially I set scrollview's position outside window, and when user clicks a button, set its position inside window. This part is OK. But scrollview displays the image but does not scroll. Isn't it enough to place in MainViewContoller.xib, set the contained content, and (at code) set its contentSize equal to the content's size? BTW: I try it at simulator currently.

  • Greasemonkey is getting an empty document.body on select Google pages.

    - by Brock Adams
    Hi, I have a Greasemonkey script that processes Google search results. But it's failing in a few instances, when xpath searches (and document body) appear to be empty. Running the code in Firebug's console works every time. It only fails in a Greasemonkey script. Greasemonkey sees an empty document.body. I've boiled the problem down to a test, greasemonkey script, below. I'm using Firefox 3.5.9 and Greasemonkey 0.8.20100408.6 (but earlier versions had the same problem). Problem: Greasemonkey sees an empty document.body. Recipe to Duplicate: Install the Greasemonkey script. Open a new tab or window. Navigate to Google.com (http://www.google.com/). Search on a simple term like "cats". Check Firefox's Error console (Ctrl-shift-J) or Firebug's console. The script will report that document body is empty. Hit refresh. The script will show a good result (document body found). Note that the failure only reliably appears on Google results obtained this way, and on a new tab/window. Turn javascript off globally (javascript.enabled set to false in about:config). Repeat steps 2 thru 5. Only now the Greasemonkey script will work. It seems that Google javascript is killing the DOM tree for greasemonkey, somehow. I've tried a time-delayed retest and even a programmatic refresh; the script still fails to see the document body. Test Script: // // ==UserScript== // @name TROUBLESHOOTING 2 snippets // @namespace http://www.google.com/ // @description For code that has funky misfires and defies standard debugging. // @include http://*/* // ==/UserScript== // function LocalMain (sTitle) { var sUserMessage = ''; //var sRawHtml = unsafeWindow.document.body.innerHTML; //-- unsafeWindow makes no difference. var sRawHtml = document.body.innerHTML; if (sRawHtml) { sRawHtml = sRawHtml.replace (/^\s\s*/, ''). substr (0, 60); sUserMessage = sTitle + ', Doc body = ' + sRawHtml + ' ...'; } else { sUserMessage = sTitle + ', Document body seems empty!'; } if (typeof (console) != "undefined") { console.log (sUserMessage); } else { if (typeof (GM_log) != "undefined") GM_log (sUserMessage); else if (!sRawHtml) alert (sUserMessage); } } LocalMain ('Preload'); window.addEventListener ("load", function() {LocalMain ('After load');}, false);

  • Ubuntu 14.04 liveusb boot screen graphic errors

    - by user568109
    I am trying to install Ubuntu 14.04 on my Lenovo Y500 laptop. It came preinstalled with Windows 8. I want to install it in a separate partition with a USB drive. I have tried both Unetbootin and universal usb installer. But for some reason the screen after booting is crappy. The screen goes blank after selecting try ubuntu or install. If I try with nomodeset option the screen only displays on a small strip on the top. Which again is split into three. Each seem to be identical. It is not decent enough to begin installation. The graphic card in my laptop is Nvidia GT650M, if it helps. Maybe the problem is related to that. Can anyone help in fixing this error when installing Ubuntu.

  • SFML 2.0 crashes anytime a method is called

    - by Ken
    This code generates an exception: #include <SFML/Graphics.hpp> #include <SFML/Window.hpp> #include <SFML/System.hpp> int main() { sf::Clock clock; clock.getElapsedTime(); return 0; } However, this doesn't crash: #include <SFML/Graphics.hpp> #include <SFML/Window.hpp> #include <SFML/System.hpp> int main() { sf::Clock clock; return 0; } I'm using SFML 2.0, Windows 7, MinGW 4.70 (Code::Blocks). I don't know why, I followed all instructions to link the libraries and nothing seems to be working. I might be missing something simple through my anger (I've been trying to run sample code for a week, nothing has been working), so can anybody throw me a bone?

How can I remove the unnecessary divs in the dialog window?

  • When designing a job queue, what should determine the scope of a job?

    - by Stuart Pegg
    We've got a job queue system that'll cheerfully process any kind of job given to it. We intend to use it to process jobs that each contain 2 tasks: Job (Pass information from one server to another) Fetch task (get the data, slowly) Send task (send the data, comparatively quickly) The difficulty we're having is that we don't know whether to break the tasks into separate jobs, or process the job in one go. Are there any best practices or useful references on this subject? Is there some obvious benefit to a method that we're missing? So far we can see these benefits for each method: Split Job lease length reflects job length: Rather than total of two Finer granularity on recovery: If we lose outgoing connectivity we can tell them all to retry The starting state of the second task is saved to job history: Helps with debugging (although similar logging could be added in single task method) Single Single job to be scheduled: Less processing overhead Data not stale on recovery: If the outgoing downtime is quite long, the pending Send jobs could be outdated

  • Python-How to call up a function from another module?

    - by user2691540
    I am making a project where I need several modules which are imported into one main module to make a pizza ordering service. Upon finishing this (to a working standard) I decided to re-code it so that the whole order is completed with one tkinter window, now instead of using input(), I use tkinter.Entry() etc. etc. To do this I had to use functions for each step so it is broken up nicely, e.g. the code asks if the user wants pickup or delivery, the user clicks a button which sets some variables and one of the buttons is then configured to say "continue" and the command leads to the next step of the pizza ordering process e.g. getting the name. The problem I have is that when I get past the last function of the first module the configured button has a command to go to a function in the second module, but it says that the command is not defined??? I have tried my way around this but cannot import the configured button variable into the next module, and anything else I tried gave no result, it simply doesn't go to the next module after the first module is done. I have made the main tkinter window in the main module and have it that it will mainloop after importing the other modules so shouldn't the function I want to call upon be defined? How can I get from one function to the next if the latter is in a seperate module? Is this possible or do I have to rethink my approach and if so how? Ok then, have made some more code to show what my problem is, this isn't what I am actually using but it's a lot shorter and has the same issue: this is the main module: import tkinter mainwindow = tkinter.Tk() # here i set the window to a certain size etc. import mod1 import mod2 mainwindow.mainloop() this is mod1: import tkinter def button1(): label.destroy() button1.destroy() button2.config(text = "continue", command = func2) def button2(): label.destroy() button1.destroy() button2.config(text = "continue", command = func2) label = tkinter.Label(text = "example label") button1 = tkinter.Button(text = "button1", command = button1) button2 = tkinter.Button(text = "button2", command = button2) label.pack() button1.pack() button2.pack() this is mod2: def func2(): button2.destroy() print ("haha it works...") I still get the problem that func2 is not defined? Thanks in advance

  • Need help creating flash animation with clickable buttons at the end.

    - by goldenfeelings
    Very inexperienced with Flash, but I hope this is simple enough for someone to walk me through. I'm ultimately trying to create a flash page for an html website that has a brief five-second animation during which 3 buttons fade in (buttons then become clickable after the animation is over). The animation part is done. Right now, I am trying to get my movie to stop and hold on the last frame, where I want to add the 3 buttons that the user can click on to take them to one 3 different html pages of my website. All instructions that I've found online have said to create a new layer for actions, insert a keyframe on the last frame of the movie, and add stop(); in the actionscript window. However, when I have the keyframe selected, my actionscript window says "current selection cannot have actions applied to it". Any ideas? I definitely don't have any objects selected, just the keyframe. Or, am I approaching this totally wrong?

  • Kinect joint coordinates and XNA animation

    - by Sweta Dwivedi
    I have written a program to record the x,y,z coordinated of the Hand joint and I want to animate my models 2D or 3D according to these coordinates. . .However the output of the x,y,z coordinates are fluctuating from -0 to 1 but not more than that.. So i assume I will need to multiply them back with the screen width and height, however it still doesnt seem to animate according to the original x,y,z points Any transformations I might be missing out? while ((line = r.ReadLine()) != null) { string[] temp = line.Split(','); int x = (int) float.Parse(temp[0]))* maxWidth); int y = (int) float.Parse(temp[1])) * maxHeight); }

    Not sure if this belongs here, feel free to push it somewhere else if needed. When i was at university we would sometimes come together into a room full of beer and fast food and crank out software in a weekend. Unfortunately the group has kind of split up and its just not possible any more. My question is now: Where can i find like-minded people on the Internet that would like to do something like this? I have an idea what i wanted to do next, but of course other people have ideas too.

  • PageRank sharing between domains?!

    - by Senthil
    I own three domains, say.. example.com, example.in, example.co.in I have bought the .in and .co.in TLDs only to protect the brand. But I have this question: If I make the other two also point to my hosting so that regardless of which one the user types, they are taken to the same website, will the PageRank be split into three and will each domain have one third the actual PR value? What should I do with the other two domains? Where should I point them to, if I don't intend to use them at all (i.e., what should I give in place of the ns1.myprovider.com, ns2.myprovider.com etc..?)
