    - by user1611107
    The following question has been asked millions of times (be patient towards it please :-)).. Why O why - can't I find ONE SIMPLE, CONCLUSIVE answer? - Would be highly appreciated! Is running a program (What_ever_job.EXE file) in ssh as : "./What_ever_job &" enough to keep it running if my own computer is shut down and ssh is closed? If not - what is the PRECISE (Please!...) way to run it? No "Screen" please, I have seen something called "nohup" (?) - how do I write the commend? Thanking you a lot on advance, Erez.

  • Implementing Scrolling Background in LibGDX game

    - by Vishal Kumar
    I am making a game in LibGDX. After working for whole a day..I could not come out with a solution on Scrolling background. My Screen width n height is 960 x 540. I have a png image of 1024 x 540. I want to scroll the background in such a way that it contuosly goes back with camera x-- as per camera I tried many alternatives... drawing the image twice ..did a lot of calculations and many others.... but finally end up with this dirty code if(bg_x2 >= - Assets.bg.getRegionWidth()) { //calculated it to position bg .. camera was initially at 15 bg_x2 = (16 -4*camera.position.x); bg_x1=bg_x2+Assets.bg.getRegionWidth(); } else{ bg_x1 = (16 -4*camera.position.x)%224; // this 16 is not proper //I think there can be other ways bg_x2=bg_x1+Assets.bg.getRegionWidth(); } //drawing twice batch.draw(Assets.bg, bg_x2, bg_y); batch.draw(Assets.bg, bg_x1, bg_y); The Simple idea is SCROLLING BACKGROUND WITH SIZE SOMEWHAT MORE THAN SCREEN SIZE SO THAT IT LOOK SMOOTH. Even after a lot of search, i didn't find an online solution. Please help.

  • Linking with an image: Background vs <img>

    - by FreshCode
    What is considered best practice (semantically) when using text with an image to link to an internal page or category? Option 1 <nav> <a href="/kittens"> <img src="kittens.png" /> <span>Kittens</span> </a> <a href="/puppies"> <img src="puppies.png" /> <span>Puppies</span> </a> </nav> Option 2 <nav> <a href="/kittens" class="kittens">Kittens</a> <a href="/puppies" class="puppies"><span>Puppies</a> </nav> where the CSS is defined: a.kittens { background-image:url("kittens.png"); width:40px; height:60px; } a.puppies { background-image:url("puppies.png"); width:40px; height:60px; } Should I use a styled background for the link, or an <img> inside the anchor element?

  • How to test whether an image is already in cache? [migrated]

    - by Evik James
    I am developing a web site that has a lot of large, high-quality images on the home page. On the home page, there is an image carousel that pulls ten high quality images from a database. The images can be 1 meg each. The carousel images aren't my problem (right now), but it has something to do with it. The problem I am trying to address right now is that I use a high quality background image that I want to continue using, it's about 180k. If I have the background in cache on the home page, I want to use it. If not, then I don't want to use it on the home page. I'll load it from a different page. When the user returns to the home page, and the background image is in cache, I want to use it. Can I test whether an image is already in cache and if so, dynamically load or NOT load based on that? You can see the home page here: http://flyingpiston2012-com.securec37.ezhostingserver.com/

  • How to make CSS URL background images show up in localhost?

    - by Joel
    Hi guys, I just installed xampp and I brought one of my live sites into it to be able to start working from localhost. So to view my site, I navigate to localhost/example.com I noticed some issues with images when on my html, I had for example: <img src="/new_pictures/05.jpg" alt="Central Market"/> Image wouldn't show up, but then I removed the / and this works: <img src="new_pictures/05.jpg" alt="Central Market"/> I seem to have a similar problem with the CSS background image, but I can't get it to work-if I remove the / there, the image doesn't show up on the live site. How do I make the background image show up on localhost? Example CSS (works in live site but not localhost): .outeremailcontainer { height:60px; width: 275px; background-image:url(/images/feather_email2.jpg); text-align:center; float:right; position:relative; z-index:1; } Thanks!

  • How do I effectively fake a div's background color using an image in the body element?

    - by janoChen
    I want to get something like the following: The dark grey is the sidebar but I want to apply that color into the body element as an image which repeats itself vertically but at the same time doesn't cover the footer (light gray). (this is the easiest way I found to stretch the color (dark gray) until the bottom.) Part of my CSS: body { color: #888; font-family: Arial, "MS Trebuchet", sans-serif; font-size: 75% } .container { margin: 0 auto; overflow: hidden; padding: 0 15px; width: 960px; } /* header */ #header { background: #444; } /* banner */ #header-top { overflow: hidden; height: 77px; width: 960px; /* ie6 hack */ } #lang { float: right; padding: 50px 0 0 0; } /* work */ #content { background: #EEE; } #content a { border-bottom: 0; } #mainbar { overflow: hidden; margin: 0 10px 0 0; width: 644; float: left; } #sidebar { background: #DDD; color: #777; overflow: hidden; margin: 20px 0 10px 0; padding: 15px; width: 240px; float: right; } #sidebar h3 { color: #888; } #about { margin: 0 0 20px; } /* footer */ #footer { color: #777; background: #DDD; clear: both; } /* contact */ #footer-top { line-height: 160%; overflow: hidden; padding: 30px 0; width: 960px; /* ie6 hack */ } #footer-bottom { font-size: 10px; margin: 15px auto; } Part of my HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"/> <title>Alex Chen - Web Development, Graphic Design, and Translation</title> <link rel="stylesheet" type="text/css" href="styles/global.css" /> </head> <body id="home"> <div id="header"> <div class="container"> <div id="header-top"> </div> </div><!-- .container --> </div><!-- #header --> <div id="content"> <div class="container"> <div id="mainbar"> </div> <!-- #mainbar--> <div id=sidebar> </div> <!-- #sidebar --> </div><!-- .container --> </div><!-- #content --> <div id="footer"> <div class="container"> <div id="footer-top"> </div><!-- #footer-top --> <div id="footer-bottom"> </div> </div><!-- .container --> </div><!-- #footer --> </body> </html>

  • Running a program in background using command-line [duplicate]

    - by user291957
    This question already has an answer here: Running programs in the background from terminal 4 answers How do I run a program in the background of a shell, with the ability to close the shell while leaving the program running which should not disturb the window i am working on? Lets say my UI is having problems or for some reason, I need to boot up a program from the terminal window. The program should not disturb my window in which i am working on but it should be opened from the command line and i should be able to get access to it using the normal shortcut ALT+TAB. Even the command line should exit after running the command I tried this .... "gedit file-name & exit" this is working fine but the gedit file is opening in the foreground (let i be working on some application like mozilla. After running the command ..... gedit file is coming upwards and i have to flip to mozilla again but the command should just open the gedit file not shifting to gedit application from the mozilla window)

  • IOs7 app crashing when in background

    - by Leonardo
    My app sometimes crashes when in background and shows the following crash log: Nov 7 12:33:31 iPad backboardd[29] <Warning>: MyApp[3096] has active assertions beyond permitted time: {( <BKProcessAssertion: 0x14680c60> identifier: Called by MyApp, from -[AppDelegate applicationDidEnterBackground:] process: MyApp[3096] permittedBackgroundDuration: 180.000000 reason: finishTask owner pid:3096 preventSuspend preventIdleSleep preventSuspendOnSleep )} Looking through other questions I found out that the crash message indicates that I didn't end a task properly, so when its time expired the OS ended it and crashed my app. So I added some NSLogs: - (void)applicationDidEnterBackground:(UIApplication *)application { [self saveContext]; [Settings setCallLock:YES]; [self saveStuff]; if ([self isBackgroundTaskNeeded]) { UIApplication* app = [UIApplication sharedApplication]; bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ [self pauseDownloads]; NSLog(@"Debug - Ending background task %d",bgTask); [app endBackgroundTask:bgTask]; NSLog(@"Debug - Background task %d ended",bgTask); bgTask = UIBackgroundTaskInvalid; }]; NSLog(@"Debug - Starting background task %d",bgTask); [self initBackground]; } } and found out that the task was called twice when it crashed: Nov 7 12:30:02 iPad MyApp[3096] <Warning>: Debug - Starting background task 7 Nov 7 12:30:30 iPad MyApp[3096] <Warning>: Debug - Starting background task 8 Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Ending background task 8 Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Background task 8 ended Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Ending background task 0 Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Background task 0 ended I wasn't able to tell when the double call happens and why. So question is why is the task being called twice and is there a way to avoid it? Edit: - (void) pauseDownloads { for (AFDownloadRequestOperation *operation in self.operationQueue.operations) { if(![operation isPaused]) { [operation pause]; } } }

  • UITableView with background UIImageView hides table controls

    - by Khanzor
    I am having a problem setting the background of UITableView to a UIImageView (see below for why I am doing this), once the view is set, it works fine, and scrolls with the UITableView, but it hides the elements of the Table View. I need to have a UIImageView as the background for a UITableView. I know this has been answered before, but the answers are to use: [UIColor colorWithPatternImage:[UIImage imageNamed:@"myImage.png"]]; Or something like (which I need to use): UIImageView *background = [MainWindow generateBackgroundWithFrame:tableView.bounds]; [tableView addSubview:background]; [tableView sendSubviewToBack:background]; The reason I need to use the latter is because of my generateBackgroundWithFrame method, which takes a large image, and draws a border around that image to the dimensions specified, and clips the remainder of the image: + (UIImageView *) generateBackgroundWithFrame: (CGRect)frame { UIImageView *background = [[[UIImageView alloc] initWithFrame:frame] autorelease]; background.image = [UIImage imageNamed:@"globalBackground.png"]; [background.layer setMasksToBounds:YES]; [background.layer setCornerRadius:10.0]; [background.layer setBorderColor:[[UIColor grayColor] CGColor]]; [background.layer setBorderWidth:3.0]; return background; } Please note: I understand that this might poorly effect performance, but I don't have the resources to go through and make those images for each potential screen in the app. Please do not answer this question with a mindless "you shouldn't do this" response. I am aware that it is possibly the wrong thing to do. How do I show my UITableView control elements? Is there something that I am doing wrong in my delegate? Here is a simplified version: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectMake(20, 20, 261, 45) reuseIdentifier:CellIdentifier] autorelease]; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; UIImage *rowBackground; NSString *imageName = @"standAloneTVButton.png"; rowBackground = [UIImage imageNamed:imageName]; UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 5, 300, 200)]; textView.backgroundColor = [UIColor clearColor]; textView.textColor = [UIColor blackColor]; textView.font = [UIFont fontWithName:@"Helvetica" size:18.0f]; Purchase *purchase = [[PurchaseModel productsPurchased] objectAtIndex:indexPath.row]; textView.text = [purchase Title]; selectedTextView.text = textView.text; UIImageView *normalBackground = [[[UIImageView alloc] init] autorelease]; normalBackground.image = rowBackground; [normalBackground insertSubview:textView atIndex:0]; cell.backgroundView = normalBackground; [textView release]; } return cell; }

  • Silverlight 4 Setting background color of textbox on focus

    - by Sean Riedel
    I am trying to set the background color of a Textbox to white on focus using a Style. My enabled Textbox has a Linear Gradient background by default: <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"> <GradientStop Color="#e8e8e8" Offset="0.0" /> <GradientStop Color="#f3f3f3" Offset="0.25" /> <GradientStop Color="#f4f4f4" Offset="0.75" /> <GradientStop Color="#f4f4f4" Offset="1.0" /> </LinearGradientBrush> </Setter.Value> </Setter> I have a focus visual state defined: <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"> <Storyboard> <DoubleAnimation Storyboard.TargetName="FocusVisualElement" Storyboard.TargetProperty="Opacity" To="1" Duration="0"/> </Storyboard> </VisualState> Here is the rest of the Control Template: <Border x:Name="Border" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="1" Opacity="1" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}"> <Grid> <Border x:Name="ReadOnlyVisualElement" Opacity="0" Background="#5EC9C9C9"/> <Border x:Name="MouseOverBorder" BorderThickness="1" BorderBrush="Transparent"> <ScrollViewer x:Name="ContentElement" Padding="{TemplateBinding Padding}" BorderThickness="0" IsTabStop="False"/> </Border> </Grid> </Border> <Border x:Name="DisabledVisualElement" Background="#A5D7D7D7" BorderBrush="#A5D7D7D7" BorderThickness="{TemplateBinding BorderThickness}" Opacity="0" IsHitTestVisible="False"/> <Border x:Name="FocusVisualElement" Background="#A5ffffff" BorderBrush="#FF72c1ec" BorderThickness="{TemplateBinding BorderThickness}" Margin="1" Opacity="0" IsHitTestVisible="False"/> On the last Border tag is where I am trying to set the background to white (#ffffff). Right now I have the opacity at A5 which does turn the background white, however it also starts to obscure the text in the box. Any higher opacity makes the text invisible so I am pretty sure that setting the background of that border is not the right way to do this. Can I set the Background color of the ContentElement somehow through a StoryBoard? Thanks.

  • Input boxes with transparent background are not clickable in IE8

    - by Viliam
    I have an absolutely positioned input box in a form. The input box has transparent background: .form-page input[type="text"] { border: none; background-color: transparent; /* Other stuff: font-weight, font-size */ } Surprisingly, I cannot select this input box by clicking on it in IE8. It works perfectly in Firefox however. The same happens for background: none. When I change the background color: background-color: red; It works fine, so this is issue associated with transparent background. Setting a border makes the input box selectable by clicking on its border only. Is there a workaround to have clickable input box with transparent background working in IE8? Update: Example. Uncomment background-color and the inputbox is selectable. You can also click on the select box, and focus the input box by pressing Shift+Tab. <!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html><head></head><body> <style type="text/css"> input[type="text"] { border: none; background: transparent; /*background-color: blue;*/ } #elem528 { position:absolute; left:155px; top:164px; width:60px; height:20px; } #elem529 { position:absolute; left:218px; top:164px; width:40px; height:20px; } </style> <img src="xxx.png" alt="" width="1000" height="1000"> <input id="elem528" maxlength="7" type="text"> <select id="elem529"></select> </body></html>

  • Tiled game: how to correct load background image ?

    - by stighy
    Hi, i'm a newbie. I'm trying to develop a 2d game (top-down view). I would like to load a standard background, a textured ground... My "world" is big, for example 3000px X 3000px. I think it is not a good idea to load a 3000px x 3000px image and move it... So, how is the best practice ? To load a single small image (64x64) and repeat it for N times ? If yes, ok, but how i can manage the "background" movement ? Thanks Bye!

  • Range subtraction in the Excel Object Model

    - by mcoolbeth
    When using Excel Interop libraries from .NET, I can find a Range object representing the cell offset from Range X by calling something like. Range Y = X.Range[2,3]; But what should I do to perform the inverse operation, ie: I have two Range objects, A and B, and I would like to find out by how many rows/columns B is offset from A. Does anyone know the easiest way to do this? Is there a library function? Thanks.

  • The fastest way to do a collection subtraction

    - by Tony
    I have two Sets. Set<B> b is the subset of Set<A> a. they're both very huge Sets. I want to subtract b from a , what's the best practice to do this common operation ? I've written to many codes like this , and I don't think it's efficient. what's your idea ? for(int i = 0 ; i < a.size(); i++) { for (int j=0 ; j < b.size() ;j++) { // do comparison , if found equals ,remove from a break; } } And I want to find an algorithm , not only applies to Sets, also works for Array.

  • Making a Background Scrolling in Stacking Game

    - by David Dimalanta
    Hmmm...Is it a good idea to use a LibGDX parallax background for making a stacking game (i.e. PAPA STACKer Lite)? For example, I'm starting to use the blocks to drag-n-drop it. Next, when the next piece reaches the top of the screen, it automatically scrolls to the next one where the available space left. Aside from that, is it also involved with the camera code (Orthographic Camera) that the screen size appeared like 720x1280 but actually it's 1440x2560 for example? And another thing, does the background scrolling have the option to scroll from start to finish and infinite?

  • Terminal as desktop background instead of wallper

    - by Janis Erdmanis
    I have come to conclusion that all my needs from nautilus is satisfied with terminal and last file manager. It also dismisses the need for multiple nautilus instances, which makes mess when I forgot how I meant to use different workspaces. The next step for my simplification would be to get rid of any possibility to open nautilus. Also I thought that my interaction with computer is file centred, therefore it makes sense to leave file manager in background of applications. Are there any ways to make terminal as desktop background with which I could interact?

  • Can not get to login screen, background starts with terminal prompt only

    - by Doug
    my uncle has Ubuntu on his work PC. Basically I came in to work today, and he had lost his UNITY side bar. I told him start with just rebooting it. He rebooted it... now it does not even get to the login screen. It gets to the background with the word UBUNTU, and the 6 or 7 dots, does it's little loading dot thing... then stops, and a black terminal opens on the top left with the background still in place. Personally, I think he screwed it up himself. He always swears he didn't touch anything, but I know better... Either way, I can't get him back into the desktop to even see if the sidebar is back. He's always screwing around pressing the wrong buttons on the login screen, hitting admin things and such... Any ideas?
