  • Samba 'include' a per user config script

    - by cb0
    It is possible to use the include = /somepath/%u.smb.conf in the global section to call a script /somepath/cb0.smb.conf if the user cb0 connects to the samba server. Unfortunately this does not wotk for me because testparm alway gives me Can't find include file /somepath/.smb.conf When I connect to the server I can enter a username and pass but it alway rejects the connection. I'm using Samba Version 3.2.5 How can I achieve to load a custom user script depending on the user that is connecting ?

  • Detect fails in setup script

    - by Lai Yu-Hsuan
    I wrote a setup script to install my prefered programs and settings after I got a new server. apt-get install git git clone http://[email protected] .vim ln -s .vimrc .vim/vimrc ... But if something wrong happens during setup, how can I interrupt the setup script, and log the error(s)? For example, if github server is down, it's obviously useless to create a symbolic link to non-existed vimrc. (or you have a better approach to initialize a server?)

  • unix script problem

    - by Darie Nicolae
    Hello everyone, I have a simple script which runs on a FreeBSD machine with the following code: #!/bin/sh `sed -i .bak '\:#start 172.0.0.3:,\:#end 172.0.0.3:d' /usr/local/etc/racoon/racoon.conf` echo $? It should delete a block of text between the two patterns. The problem is that if I run the sed command directly from shell it works, if i run the script the return code is 0. Why's that?

  • Why can't I access my own web server from my local network?

    - by frenetic
    I have a web server in my home network and I'm using ZoneEdit for dynamic DNS. It's accessible perfectly to everyone outside of my local network, but since I switched to a Gateway 2Wire DSL modem/router I'm unable to use the domain to access the server from my network. I can access it via a local IP or by putting it in my Windows hosts file but this is annoying to do on every computer and for every subdomain. Any idea how I can fix this? Thanks!

  • Autohotkey numpad mouse script, events propagating to some programs, but not others

    - by jhnclvr
    I have an issue when trying out one of the example scripts in the autohotkey docs: http://www.autohotkey.com/docs/scripts/NumpadMouse.htm When a program like Notepad++ gets focus, the script does not seem to receive key events, and instead the key events seem to be consumed by Notepad++. Is there a modification to the script that would allow it to receive the events no matter what window was open?

  • Update MS Windows XP via batch script

    - by oshirowanen
    Is it possible to update WXP using a batch script? Basically, I would like to run a batch script, which installs all important updates in the background accepting any dialog boxes which need user interaction. EDIT 1: I know I can enable the "Automatically download and install" option to do this, but I have about 100 computers to do, so it would be nice if it can be done via a batch file. That way, I can use the software we already have to run a batch file on all computers with a single click.

  • How to run a logon script but not as the current user

    - by user139951
    I want to create a log of when people login or logout of computers in a computer lab. My first idea was to just create login/logout scripts that contact a server, but the problem is since these scripts would run as the current user, that they would then be able to run this script outside of these two occasions. Is there any way to go about running a login/logout script as the domain computer rather than as the user?

  • Optimized Image Loading in a UIScrollView

    - by Michael Gaylord
    I have a UIScrollView that has a set of images loaded side-by-side inside it. You can see an example of my app here: http://www.42restaurants.com. My problem comes in with memory usage. I want to lazy load the images as they are about to appear on the screen and unload images that aren't on screen. As you can see in the code I work out at a minimum which image I need to load and then assign the loading portion to an NSOperation and place it on an NSOperationQueue. Everything works great apart from a jerky scrolling experience. I don't know if anyone has any ideas as to how I can make this even more optimized, so that the loading time of each image is minimized or so that the scrolling is less jerky. - (void)scrollViewDidScroll:(UIScrollView *)scrollView{ [self manageThumbs]; } - (void) manageThumbs{ int centerIndex = [self centerThumbIndex]; if(lastCenterIndex == centerIndex){ return; } if(centerIndex >= totalThumbs){ return; } NSRange unloadRange; NSRange loadRange; int totalChange = lastCenterIndex - centerIndex; if(totalChange > 0){ //scrolling backwards loadRange.length = fabsf(totalChange); loadRange.location = centerIndex - 5; unloadRange.length = fabsf(totalChange); unloadRange.location = centerIndex + 6; }else if(totalChange < 0){ //scrolling forwards unloadRange.length = fabsf(totalChange); unloadRange.location = centerIndex - 6; loadRange.length = fabsf(totalChange); loadRange.location = centerIndex + 5; } [self unloadImages:unloadRange]; [self loadImages:loadRange]; lastCenterIndex = centerIndex; return; } - (void) unloadImages:(NSRange)range{ UIScrollView *scrollView = (UIScrollView *)[[self.view subviews] objectAtIndex:0]; for(int i = 0; i < range.length && range.location + i < [scrollView.subviews count]; i++){ UIView *subview = [scrollView.subviews objectAtIndex:(range.location + i)]; if(subview != nil && [subview isKindOfClass:[ThumbnailView class]]){ ThumbnailView *thumbView = (ThumbnailView *)subview; if(thumbView.loaded){ UnloadImageOperation *unloadOperation = [[UnloadImageOperation alloc] initWithOperableImage:thumbView]; [queue addOperation:unloadOperation]; [unloadOperation release]; } } } } - (void) loadImages:(NSRange)range{ UIScrollView *scrollView = (UIScrollView *)[[self.view subviews] objectAtIndex:0]; for(int i = 0; i < range.length && range.location + i < [scrollView.subviews count]; i++){ UIView *subview = [scrollView.subviews objectAtIndex:(range.location + i)]; if(subview != nil && [subview isKindOfClass:[ThumbnailView class]]){ ThumbnailView *thumbView = (ThumbnailView *)subview; if(!thumbView.loaded){ LoadImageOperation *loadOperation = [[LoadImageOperation alloc] initWithOperableImage:thumbView]; [queue addOperation:loadOperation]; [loadOperation release]; } } } } EDIT: Thanks for the really great responses. Here is my NSOperation code and ThumbnailView code. I tried a couple of things over the weekend but I only managed to improve performance by suspending the operation queue during scrolling and resuming it when scrolling is finished. Here are my code snippets: //In the init method queue = [[NSOperationQueue alloc] init]; [queue setMaxConcurrentOperationCount:4]; //In the thumbnail view the loadImage and unloadImage methods - (void) loadImage{ if(!loaded){ NSString *filename = [NSString stringWithFormat:@"%03d-cover-front", recipe.identifier, recipe.identifier]; NSString *directory = [NSString stringWithFormat:@"RestaurantContent/%03d", recipe.identifier]; NSString *path = [[NSBundle mainBundle] pathForResource:filename ofType:@"png" inDirectory:directory]; UIImage *image = [UIImage imageWithContentsOfFile:path]; imageView = [[ImageView alloc] initWithImage:image andFrame:CGRectMake(0.0f, 0.0f, 176.0f, 262.0f)]; [self addSubview:imageView]; [self sendSubviewToBack:imageView]; [imageView release]; loaded = YES; } } - (void) unloadImage{ if(loaded){ [imageView removeFromSuperview]; imageView = nil; loaded = NO; } } Then my load and unload operations: - (id) initWithOperableImage:(id<OperableImage>) anOperableImage{ self = [super init]; if (self != nil) { self.image = anOperableImage; } return self; } //This is the main method in the load image operation - (void)main { [image loadImage]; } //This is the main method in the unload image operation - (void)main { [image unloadImage]; }

  • How to eager load in WCF Ria Services/Linq2SQLDomainModel

    - by Aggelos Mpimpoudis
    I have a databound grid at my view (XAML) and the Itemsource points to a ReportsCollection. The Reports entity has three primitives and some complex types. These three are shown as expected at datagrid. Additionally the Reports entity has a property of type Store. When loading Reports via GetReports domain method, I quickly figure out that only primitives are returned and not the whole graph of some depth. So, as I wanted to load the Store property too, I made this alteration at my domain service: public IQueryable<Report> GetReports() { return this.ObjectContext.Reports.Include("Store"); } From what I see at the immediate window, store is loaded as expected, but when returned to client is still pruned. How can this be fixed? Thank you!

  • Loading Separate Pages With Animation in JQTouch

    - by Donovan Keith
    I'm trying to convert a database-driven multiple-choice-style study website (written in JSP) into an iPhone app using JQTouch. If I load all of the Q&A's into their own divs in the same file I can easily link and animate between them using links to hashtags, like: a class="button" href="#question22" Unfortunately this isn't practical. The logic of the website as it currently works requires calls to a number of dynamically generated pages; I can't include every question in its own div in the same flat file. How would I go about dynamically (pre)loading the next question (a JSP page like AskQuestion.jsp?questionId=Kzhctand ) then serving that up within the app after the user presses a button? Thanks for any help you might offer. -Donovan

  • "not well-formed" warning when loading client-side JSON in Firefox via jQuery.ajax

    - by Zhami
    I am using jQuery's ajax method to acquire a static JSON file. The data is loaded from the local file system, hence there is no server, so I can't change the mime type. This works fin in Safari, but Firefox (3.6.3) reports the file to be "not well-formed". I am aware of, and have reviewed, a similar post here on Stack Overflow: http://stackoverflow.com/questions/677902/not-well-formed-error-in-firefox-when-loading-json-file-with-xmlhttprequest I believe my JSON is well-formed: { "_": ["appl", "goog", "yhoo", "vz", "t"] } My ajax call is straightforward: $.ajax({ url: 'data/tickers.json', dataType: 'json', async: true, data: null, success: function(data, textStatus, request) { callback(data); } }); If I wrap the JSON with a document tag: <document>JSON data</document> as was mentioned in the above referenced posted question, the ajax call fails with a parserror. So: is there a way to avoid the Firefox warning when reading in client-side JSON files?

  • Loading WPF satellite resources dynamically

    - by BJ
    Hello! I've read about satellite-assemblies being used in WPF localizations. However, I would like to ask if there is a way to load the satellite-assemblies without following the pre-defined directory structure that depends on the language (ex. If the system language is English, the WPF application looks for the satellite-assembly inside the "en-US" subfolder). This is because I would like to simply swap the satellite-assemblies when distributing the software package without having to create a specific folder per language that would hold the assemblies. I would just like to have the satellite-assembly and the main executable in the same directory. Is this possible and is there even an easy way to do this like simply loading the resource file on application startup once? Thanks!

  • Loading Magento child html outside of Magento

    I am loading Magento blocks outside of Magento for certain parts of my site. I can do this successfully with something similar the following. require_once $docRoot.'/app/Mage.php'; umask(0); Mage::app('default'); ... $layout = Mage::getSingleton('core/layout'); $block = $layout->createBlock('Mage_Page_Block_Html_Header'); $block->setTemplate('page/html/header.phtml'); echo $block->renderView(); The problem is that if the block I am rending has child blocks(html) they are not included in the output. In the example above the file header.phtml contains the following call for child html that is missing from the output. ... <?php echo $this->getChildHtml('topLinks') ?> ...
