  • Find record whose field 'name' not contained within any other record

    - by charlie
    I have a model Foo with a String bar and a String name. Some records' bar contain the name of other records in them. This is intentional. I want to find the "root Foo" records - that is, the ones where their name do not appear in the bar records of any other Foo records. Example: Foo id: 1 name: 'foo1' bar: 'something something' id: 2 name: 'foo2' bar: 'foo1 something' id: 3 name: 'foo3' bar: 'foo1, foo4' My method root_foos would return foo2 and foo3 since their names do not appear in any bar string. edit: I don't want to use a relation or foreign key here - just this method.

  • How can Java assignment be made to point to an object instead of making a copy?

    - by Matthew Piziak
    In a class, I have: private Foo bar; public Constructor(Foo bar) { this.bar = bar; } Instead of creating a copy of bar from the object provided in the parameter, is it possible to include a pointer to bar in the constructor such that changing the original bar changes the field in this object? Another way of putting it: int x = 7; int y = x; x = 9; System.out.print(y); //Prints 7. It is possible to set it up so that printing y prints 9 instead of 7?

  • How do i get my search bar to actually work?

    - by Sam
    Hey guys, I've got a search bar and it looks fine, but i don't really know how to make it search the whole of my site...

  • Help me set up ssl.conf for multiple domains (name-based vhosts in ssl.conf?)

    - by mmattax
    In my httpd.conf: If I have my virtual host configured as: NameVirtualHost *:80 <VirtualHost *:80 ServerName foo.com ServerAlias www.foo.com Include conf.d/foo.conf </VirtualHost <VirtualHost *:80 ServerName bar.com ServerAlias www.bar.com Include conf.d/bar.conf </VirtualHost Can I get by with a single domain SSL certificate or must I purchase a wildcard SSL certificate to handle the www subdomain? I am now trying to configure the ssl.conf file, can I use name-based vhosts in my ssl.conf file like this: NameVirtualHost *:443 <VirtualHost *:443 ServerName foo.com ServerAlias www.foo.com ... Include conf.d/foo.conf </VirtualHost <VirtualHost *:443 ServerName bar.com ServerAlias www.bar.com ... Include conf.d/bar.conf </VirtualHost or do I need IP based vhosts? If this is possible, what kind of cert would I need in order to do this?

  • iTunes Title Bar is Equal to the Location of the Library file?

    - by Urda
    I have never been able to get a clear answer on why the latest edition of iTunes does this. I have my entire iTunes library located in C:\itunes\ and the library data files inside C:\itunes\!library_info for backup purposes. However when version 9 of iTunes came out it went from having iTunes as the title, to !library_info. Anyway to get around this without moving my data files away? Annoying "feature" if that is what it is. Again Apple support and forums were of no help to me. Anyone have insight on this? System Info: Windows Vista x86 Ultimate, latest updates. iTunes Version 9.0.3.15 Screenshot: http://farm5.static.flickr.com/4072/4414557544_d0b25eb64c_o.jpg Flickr Page: http://www.flickr.com/photos/urda/4414557544/

  • "sed" regex help: Replacing characters

    - by powerbar
    I want to change characters in a XML file by using sed. The input looks like this: <!-- Input --> <root> <tree foo="abcd" bar="abccdcd" /> <dontTouch foo="asd" bar="abc" /> </root> Now I want to change all c to X in the bar tag of the tree element. <!-- Output --> <root> <tree foo="abcd" bar="abXXdXd" /> <dontTouch foo="asd" bar="abc" /> </root> How is the correct sed command? Please consider, there can be more than one occurence of c (next to each other or not) in one tag... I tried this myself, but it won't change multiple c, and it does append a X :( sed -i 's/\(<tree.*bar=\".*\)c\(.*\"\/>\)/\1X\2/g' Input.xml

  • How can I get Skype to not stay minimized in the task bar?

    - by Johannes Rössel
    Since two or three updates Skype insists taking up a taskbar slot for its main window (I set it to use the “Compact View”, but it applies to the default view as well). Since I don't need the main window most of the time since I have individual windows for the contacts I'm writing to this is ? a taskbar button wasted if no other Skype windows are open and ? still in the way when there are other windows open as it's a window I never need but still sometimes mis-click on when the thumbnails show up. Is there a way to send Skype to the Notification area again?

  • .htaccess folder rewrite

    - by Lisa
    I have 3 URLS all pointing to the same site. www.abc.co.uk www.xyz.com www.123abc.org I have a folder /foo/bar which has lots of sub folders and files in etc. I want to rewrite this to /bar. So if I have www.abc.co.uk/foo/bar/sheep/page.html I want it to redirect to www.abc.co.uk/bar/sheep/page.html. Is this possible. Sometime I may have a URL like www.abc.co.uk/foo/bar/foo/page.html so this would become www.abc.co.uk/bar/foo/page.html. Only the first instance of foo would be rewritten.

  • What's the best way to rewrite traffic from domainA.com/foo to domainB.com/bar while properly rewrit

    - by Chad DePue
    We have a number of sites that have blogs, like domainA.com/blog domainB.com/blog and we host the blogs on wordpress multi user: our-separate-wordpress-site.com/domaina_blog our-separate-wordpress-site.com/domainb_blog for SEO reasons we really, really want domainA.com/blog to be the blog url, not the other path. But we don't see any examples where this is done, because we need not to just rewrite the traffic, but cookies as well... is this possible with a webserver or a reverse proxy?

  • Do I need to have a company so that I can buy an SSL certificate that will display green at the address bar?

    - by André Pena
    I have a non-comercial website in which the users store some sensitive information so I feel the need to have a SSL certificate, but it seems that if I don't have a registered company I can't buy a green certificate. I have some related questions: Is it true that if I don't have a company, I can't have a green certificate? If I issue a standard (non-business) certificate that won't go green (from GoDadday, for instance), will it go red? Or will it have a less ugly display.. something more neutral that won't scary the user.

  • Homedir inside homedir restricted access

    - by blid
    On my VPS i've installed debian, apache+php. I have 2 users: foo and bar. Apache is configured to execute php files from /home/foo/htdocs. I created dir: /home/foo/htdocs/bar/ and made it home dir for user bar. Hover, I need to make a restriction: bar can't read, write or executre any files outside his own dir, but Apache has to be able execute all php files from /htdocs. I tried to chown the bar dir only for user bar, also experimented a lot with chmod but without a result so far. If there's any better way to satisfy my needs don't hesitate to write about it. Thanks in advance

  • Is there a way to automatically keep Chrome/Ask Tool Bar from installing?

    - by hydroparadise
    So of lately, I've had to warn my users to watch out for unwanted programs that are coming in with Adobe Flash and Java updates. Adobe seems to be pushing Google's Chrome and Java with the Ask.com Toolbar. I admit that it could be much worse because both instance simply require an uncheck during some point of the update process, but on a large scale, prevention is better than confrontation. Any suggestions?

  • How to get aero themed windows and a task bar on Ubuntu 11.10?

    - by The OS Man
    I know some themes that make all of ubuntu look like windows 7, but I just want the windows to be aero themed. How can I do this? Also, I want the Windows 7 taskbar (including the start orb) in ubuntu. Please don't suggest getting windows 7, because I can't. I'm new to ubuntu (Windows xp user), so I don't want to go into the command line. Finally, I had been thinking about using a program called ViStart. Will it work? Please answer!

  • Scroll bar for vim(curses-based one, not gvim)?

    - by xiaq
    As a Linux user, I have been quite comfortable with CLI and TUI tools, but I miss the little scrollbar present in almost every GUI program. It has always been easier for me to know how long the file is and where I am from the scrollbar instead of "9752 lines, 24%". What I expect is a ASCII scrollbar that looks like | | | | # # # | | | and I can configure to appear on the left or right (and if on the left, the relative position to line numbers and fold marks). Is there already a Vim plugin to do this, or how can I write my own one? Vim's plugin framework doesn't seem to support such UI modifications directly.

  • How do I display the full title bar in Firefox 29?

    - by ceiling cat
    With Firefox 29, it no longer displays the full title. For example, in this screen shot here, it only display the beginning of "The New York Times - Breaking News, World News & Multimedia". How can I make it display the whole thing? EDIT (for clarification): I'd like to see the full title of the web page of the tab I am on at all times (hovering the cursor would not work for me). Making the tab full width only works if I have 1 or 2 tabs, but most of the time I have many more tabs so this wouldn't work for me.

  • Misunderstanding Scope in JavaScript?

    - by Jeff
    I've seen a few other developers talk about binding scope in JavaScript but it has always seemed to me like this is an inaccurate phrase. The Function.prototype.call and Function.prototype.apply don't pass scope around between two methods; they change the caller of the function - two very different things. For example: function outer() { var item = { foo: 'foo' }; var bar = 'bar'; inner.apply(item, null); } function inner() { console.log(this.foo); //foo console.log(bar); //ReferenceError: bar is not defined } If the scope of outer was really passed into inner, I would expect that inner would be able to access bar, but it can't. bar was in scope in outer and it is out of scope in inner. Hence, the scope wasn't passed. Even the Mozilla docs don't mention anything about passing scope: Calls a function with a given this value and arguments provided as an array. Am I misunderstanding scope or specifically scope as it applies to JavaScript? Or is it these other developers that are misunderstanding it?

  • Only 1080p youtube videos work properly

    - by oshirowanen
    I have Ubuntu 12.04 64bit installed/full updated and have noticed that I can only play 1080p youtube videos properly on full screen. All other resolutions, 480, 720, 1440 etc do not go into full screen properly. Please have a look at the attached images. You will notice that only the 1080p video has the video control bar right at the bottom with a respectable text size. All other videos don't have the video control bar right at the bottom on the screen, and the control bar text is too small. I've had this problem for ages, but finally decided to ask about it. 480p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides: 720p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides and the text is tiny: 1080p: This is the only one that works as expected, i.e. controls right at the bottom, and good font size and no borders on the sides: 1440p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides: How do I correct this problem so I can play all different video resolutions at full screen. The flash version I have installed in Chromium is Adobe Flash Player - Version: 11.2 r202 - Shockwave Flash 11.2 r202

  • Windows domain full hostnames cannot be resolved resulting in intranet not working

    - by OpethR
    the domain: is foo.bar.local full hostname is: bla.foo.bar.local short hostname is: bla I installed winbind. here is my smb.conf: name resolve order = lmhosts host wins bcast here is my nsswitch.conf: hosts: files mdns4_minimal [NOTFOUND=return] dns wins mdns4 when I try to ping full hostname, I get: "ping: unknown host" when I ping short hostname it works and shows me PING bla.foo.bar.local (10.11.20.135) 56(84) bytes of data. 64 bytes from bla.foo.bar.local (10.11.20.135): icmp_req=1 ttl=62 time=49.7 ms *notice that it manages to get the full hostname!? :S now the only reason I need it is cuz I'm trying to reach intranet websites. when I type short hostname "bla" in firefox address bar, it automatically changes it to the full hostname (which is good, right?!) but then it says: Server not found Firefox can't find the server at bla.foo.bar.local. what am I doing wrong? it's driving me nutz. so if you are wandering then yes, it is company intranet I'm trying to reach from ubuntu. If I use my crappy winxp everything is working perfectly well.

  • Get the screen height in Android

    - by Dan Bray
    How can I get the available height of the screen in Android? I need to the height minus the status bar / menu bar or any other decorations that might be on screen and I need it to work for all devices. Also, I need to know this in the onCreate function. I know this question has been asked before but I have already tried their solutions and none of them work. Here are some of the things I have tried: I have tested this code on API 7 - 17. Unfortunately, on API 13 there is extra space at bottom both horizontally and vertically and on API 10, 8, and 7 there is not enough space at the bottom both horizontally and vertically. (I have not tested on obsolete API's): Display display = getWindowManager().getDefaultDisplay(); DisplayMetrics metrics = new DisplayMetrics(); display.getMetrics(metrics); screenWidth = metrics.widthPixels; screenHeight = metrics.heightPixels; TypedValue tv = new TypedValue(); if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true)) screenHeight -= TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics()); } int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) screenHeight -= getResources().getDimensionPixelSize(resourceId); This does not take into account the status bar / menu bar: Display display = getWindowManager().getDefaultDisplay(); screenWidth = display.getWidth(); screenHeight = display.getHeight(); Neither does this: Point size = new Point(); getWindowManager().getDefaultDisplay().getSize(size); screenWidth = size.x; screenHeight = size.y; Nor this: Point size = new Point(); getWindowManager().getDefaultDisplay().getRealSize(size); screenWidth = size.x; screenHeight = size.y; This does not work: Display display = getWindowManager().getDefaultDisplay(); DisplayMetrics metrics = new DisplayMetrics(); display.getMetrics(metrics); // since SDK_INT = 1; screenWidth = metrics.widthPixels; screenHeight = metrics.heightPixels; try { // used when 17 > SDK_INT >= 14; includes window decorations (statusbar bar/menu bar) screenWidth = (Integer) Display.class.getMethod("getRawWidth").invoke(display); screenHeight = (Integer) Display.class.getMethod("getRawHeight").invoke(display); } catch (Exception ignored) { // Do nothing } try { // used when SDK_INT >= 17; includes window decorations (statusbar bar/menu bar) Point realSize = new Point(); Display.class.getMethod("getRealSize", Point.class).invoke(display, realSize); screenWidth = realSize.x; screenHeight = realSize.y; } catch (Exception ignored) { // Do nothing } I then used the following code to subtract the height of the status bar and menu bar from the screen height: int result = 0; int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) result = getResources().getDimensionPixelSize(resourceId); screenHeight -= result; result = 0; if (screenHeight >= screenWidth) resourceId = getResources().getIdentifier("navigation_bar_height", "dimen", "android"); else resourceId = getResources().getIdentifier("navigation_bar_height_landscape", "dimen", "android"); if (resourceId > 0) result = getResources().getDimensionPixelSize(resourceId); screenHeight -= result; On API 17 it correctly calculates the height of the status bar and menu bar in portrait but not in landscape. On API 10, it returns 0. I need it to work ideally on all devices or minimum API 7. Any help would be greatly appreciated.

  • Why is my WPF splash screen progress bar out of sync with the execution of the startup steps?

    - by denny_ch
    Hello, I've implemented a simple WPF splash screen window which informs the user about the progress of the application startup. The startup steps are defined this way: var bootSequence = new[] { new {Do = (Action) InitLogging, Message = "Init logging..."}, new {Do = (Action) InitNHibernate, Message = "Init NHibernate..."}, new {Do = (Action) SetupUnityContainer, Message = "Init Unity..."}, new {Do = (Action) UserLogOn, Message = "Logon..."}, new {Do = (Action) PrefetchData, Message = "Caching..."}, }; InitLogging etc. are methods defined elsewhere, which performs some time consuming tasks. The boot sequence gets executed this way: foreach (var step in bootSequence) { _status.Update(step.Message); step.Do(); } _status denotes an instance of my XAML splash screen window containing a progress bar and a label for status information. Its Update() method is defined as follows: public void Update(string status) { int value = ++_updateSteps; Update(status, value); } private void Update(string status, int value) { var dispatcherOperation = Dispatcher.BeginInvoke( DispatcherPriority.Background, (ThreadStart) delegate { lblStatus.Content = status; progressBar.Value = value; }); dispatcherOperation.Wait(); } In the main this works, the steps get executed and the splash screen shows the progress. But I observed that the splash screen for some reasons doesn't update its content for all steps. This is the reason I called the Dispatcher async and wait for its completion. But even this didn't help. Has anyone else experienced this or some similar behaviour and has some advice how to keep the splash screen's update in sync with the execution of the boot sequence steps? I know that the users will unlikely notice this behaviour, since the splash screen is doing something and the application starts after booting is completed. But myself isn't sleeping well, because I don't know why it is not working as expected... Thx for your help, Denny

  • pushing view controller inside a tab bar from app delegate, after a notification.

    - by shani
    hi i have an app with tab bar and a navigation controller inside every tab. i have set a notification that when it lunches the user can get lunch the app by pressing the action on the alert. i want to redirect the user to one of the views inside one of the controllers. i have tried this: (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif { NSArray *data = [notif.userInfo objectForKey:@"todoDate"]; NSInteger ind = [[data objectAtIndex:2] integerValue]; QuickViewController *detailViewController ; detailViewController = [[QuickViewController alloc] initWithNibName:@"QuickViewController" bundle:nil]; detailViewController.title = @"Edit"; detailViewController.personName = [data objectAtIndex:0]; detailViewController.DelitionDate=[data objectAtIndex:1]; detailViewController.personCategory=@"NO Category"; detailViewController.personID = ind r ; rootControler.selectedIndex = 1; [rootControler.tabBarController.selectedViewController.navigationController pushViewController:detailViewController animated:YES]; } but nothing is happening (no crashing) except of the :rootControler.selectedIndex = 1; when i tried : presentModalViewController i got the view perfectly but without the navigation controller. thanks shani
