  • Any way to make service do not autostart in Ubuntu/Debian, but leave K00 scripts in place?

    - by Evgenyt
    I need to have only stop scripts in rcN.d (runlevels 0,1,6) for apache2. So that I always start it by myself, but when reboot occurs server will shut down apache2 properly. And when I change runlevel 2-3 server doesnt' touch apache daemon (leaving it in the state it is). Basically, I just need a legal way to remove apache2 startup symlinks from rc2.d - rc5.d. With tools like update-rc.d. I can just remove those symlinks by hands, but I'm not sure if this is a proper way for this.

  • SSH connection falling down

    - by kappa
    I've set up a connection with autossh that creates some tunnels at system startup, but if I try to connect, after successful login (with RSA key) connection fall down, here a trace: debug1: Authentication succeeded (publickey). debug1: Remote connections from LOCALHOST:5006 forwarded to local address localhost:22 debug1: Remote connections from LOCALHOST:6006 forwarded to local address localhost:80 debug1: channel 0: new [client-session] debug1: Requesting [email protected] debug1: Entering interactive session. debug1: remote forward success for: listen 5006, connect localhost:22 debug1: remote forward success for: listen 6006, connect localhost:80 debug1: All remote forwarding requests processed debug1: Sending environment. debug1: Sending env LANG = it_IT.UTF-8 debug1: Sending env LC_CTYPE = en_US.UTF-8 debug1: client_input_channel_req: channel 0 rtype exit-status reply 0 debug1: client_input_channel_req: channel 0 rtype [email protected] reply 0 debug1: channel 0: free: client-session, nchannels 1 Transferred: sent 2400, received 2312 bytes, in 1.3 seconds Bytes per second: sent 1904.2, received 1834.4 debug1: Exit status 1 What can be the problem?

  • jquery hover menu question

    - by vondip
    Hi all, I am developing a small web app that uses jquery quite a lot. In my app a user can hover an image, which becomes bigger after a few seconds, giving him more details. The problem is that when the image enlarges the image, it takes over the area of the nearby images as well. Now, if the user goes over the second red square (numbered as 2) I would like the currently enlarged image to disappear and instead enlarge the image pictured below as square two. I am not much of a painter, but I have attached a small image to help illustrate the problem. In short, How can I tell jquery to detect when the mouse is over red square number two, yet not raising the event if the mouse is over green square. [in my demo picture, hovering on point]

  • HDMI and DVI connected monitors not in dual view on Windows 7 (Intel onboard Gigabyte)

    - by Nux
    I have a HDMI to DVI cable which is connected to one monitor (HDMI is on PC side) and DVI-DVI connected to other monitor. This seems to work up until the system is fully loaded (the startup logo animation is shown on two screens). When and after I log in only one monitor is active (HDMI-DVI). I'm also unable to detect the other monitor (DVI-DVI). Any ideas what might be wrong with the setup? Also when I uninstall the Intel Graphics driver both screens are on, but only duplication works. GA-Z68A-D3H-B3, Intel Z68 Chipset, with fresh VGA driver (15.26.1.64.2618).

  • How to force HttpWebRequest to use cache in ASP.NET environment?

    - by piotrsz
    In my ASP.NET app I use HttpWebRequest for fetching external resources which I'd like to be cached. Consider the following code: var req = WebRequest.Create("http://google.com/"); req.CachePolicy = new HttpRequestCachePolicy(HttpRequestCacheLevel.CacheIfAvailable); var resp = req.GetResponse(); Console.WriteLine(resp.IsFromCache); var answ = (new StreamReader(resp.GetResponseStream())).ReadToEnd(); Console.WriteLine(answ.Length); HttpWebRequest uses IE cache, so when I run it as normal user, data is cached to %userprofile%\Local Settings\Temporary Internet Files and next responses are read from cache. I thought that when such code is run inside ASP.NET app, data will be cached to ...\ASPNET\Local Settings\Temporary Internet Files but it is not and cache is never used. What I am doing wrong? How to force HttpWebRequest to use cache in ASP.NET environment?

When I run my app and enter the url "/Admin/Pages/List" I'm getting an The resource cannot be found error. When I enter /Pages/List, the Action method is hit but the view is not found,because the app is searching in wrong directories ~/Views/Pages/List.aspx ~/Views/Pages/List.ascx ~/Views/Shared/List.aspx ~/Views/Shared/List.ascx the view is in /Admin/Pages/List.

  • how to customize debian installation cd for your needs

    - by Frank
    I have with me a Debian CD, which I want to customize for my own needs. I have extracted the CD and started to change some parts of it, e.g Splash screen (splash.png) installer Title (through isolinux.cfg) etc These are the things that I want to do: Change the Splash logo at start up of installation to have my own (which is done) Change the grub boot parameters to use my comapny name on it. Change the set of packages in it, so that I can have my own set of packages in it and only those packages are installed Do some post installation steps Customize it's startup and login screen to have my company name. After I am done with this customization, I need to build its live installer CD so that I can install it on my own, on any other system.

  • Any good way to set the exit status of a Cocoa application?

    - by buglesareking
    I have a Cocoa app which interacts with a server and displays a GUI. If there is a fatal error, I display an alert and exit. I'd like to set the exit status to a non-zero value to reflect that an error occurred, for ease of interaction with some other UNIX based tools. Unfortunately I've been unable to find a good way to do so - NSApplication doesn't seem to have any way to set an exit status. At the moment, I've subclassed NSApplication and added an exitStatus ivar (which I set in my app delegate when necessary), then overridden -terminate: so that it calls exit(exitStatus). This works fine, but it seems a bit grungy to me, not to mention that I may be missing something important that the stadnard `terminate: is doing behind the scenes. I can't call [super terminate:sender] in my subclassed method, because that exit()s without giving me a chance to set the status. Am I missing something obvious?

  • SQLite3 or SQLite Manager make me crazy !!! Please help me !! I have a presentation next week

    - by ahmet732
    My friend added 90 rows into the database, I tied it up to my app. In my table view name of my variables are shown in proper fashion but when I tapped one of them, in detailsViewController their description is wrong. It shows very old description of variables not the new ones in database. Moreover, it displays the same description for different variables. What's the problem ? What am i missing? My database is correct. It displays same desscriptions for different values. It makes me worried about. Additionally, when I added a new row to my db, it accepts it but it does not perceive it when i run the app. It shows new row in my tableview if and only if I change the name of my db file. I do not want to use another SQL manager ..

  • Problems persisting Core Data structures on iPhone/iPad

    - by Rivier
    I have an iPhone/iPad app using Core Data to keep my application data. Sometimes, even though I don't get any error messages, the data is not really saved so when the app starts anew, it's all gone. This problem seems to disappear after physically rebooting the device, but otherwise it's pretty random and hard to track. Has anyone seen a similar issue? Also, it seems to happen more often in the iPhone 1st generation, less so in the 3G/3GS, and seldom in the iPad. Very strange...

  • MySQL service was shut down - why?

    - by Tony
    I have installed MySQL Server 5.5 on the WIndows Server 2008 R2. In the services.msc I see that it has the Startup Type option set to Automatic. Everything was fine until today when that service was somehow turned off, but I did not do this. So, 1) what can makes that service to be shutted down ? 2) Maybe is there any error log ? 3) Is it possible to set that service to be automatically turned on if that situation will come again ?

  • How do you delete a core data entry from the detail view?

    - by Sam
    I am working with an app similar to apple's core data recipes sample code. I want to be able to delete the entry from the detail view, much like apple's contacts app. The code below is deleting the 1st entry and not the selected entry. Not sure what I am doing wrong. NSIndexPath *indexPath = [myTableView indexPathForSelectedRow]; NSManagedObjectContext *context = [fetchedResultsController managedObjectContext]; [context deleteObject:[fetchedResultsController objectAtIndexPath:indexPath]]; [myTableView reloadData];

  • How to stop nginx on Mac OS X

    - by Alex Kaushovik
    I've installed nginx server on my Mac from MacPorts: sudo port install nginx. Then I followed the recommendation from the port installation console and created the launchd startup item for nginx, then started the server. It works fine (after I renamed nginx.conf.example to nginx.conf and renamed mime.types.example to mime.types), but I couldn't stop it... I tried sudo nginx -s stop - this doesn't stop the server, I can still see "Welcome to nginx!" page in my browser on http://localhost/, also I still see master and worker processes of nginx with ps -e | grep nginx. What is the best way to start/stop nginx on Mac? BTW, I've added "daemon off;" into nginx.conf - as recommended by various resources. Thank you.

  • Rails: Settingslogic accessible to users?

    - by neezer
    I have my app configured with Settingslogic, which I love. My question is how to I make a page on my Rails app where Administrators can make changes to the settings specified in config/settings.yml?? I assume said page would have to read and display appropriate form fields for all the values in the YAML file, then save those values back to config/settings.yml? Would those settings take effect immediately or would the server need to be restarted? Bit lost here. Thanks. Related: http://stackoverflow.com/questions/2907643/rails-application-settings

  • Using Core Data Concurrently and Reliably

    - by John Topley
    I'm building my first iOS app, which in theory should be pretty straightforward but I'm having difficulty making it sufficiently bulletproof for me to feel confident submitting it to the App Store. Briefly, the main screen has a table view, upon selecting a row it segues to another table view that displays information relevant for the selected row in a master-detail fashion. The underlying data is retrieved as JSON data from a web service once a day and then cached in a Core Data store. The data previous to that day is deleted to stop the SQLite database file from growing indefinitely. All data persistence operations are performed using Core Data, with an NSFetchedResultsController underpinning the detail table view. The problem I am seeing is that if you switch quickly between the master and detail screens several times whilst fresh data is being retrieved, parsed and saved, the app freezes or crashes completely. There seems to be some sort of race condition, maybe due to Core Data importing data in the background whilst the main thread is trying to perform a fetch, but I'm speculating. I've had trouble capturing any meaningful crash information, usually it's a SIGSEGV deep in the Core Data stack. The table below shows the actual order of events that happen when the detail table view controller is loaded: Main Thread Background Thread viewDidLoad Get JSON data (using AFNetworking) Create child NSManagedObjectContext (MOC) Parse JSON data Insert managed objects in child MOC Save child MOC Post import completion notification Receive import completion notification Save parent MOC Perform fetch and reload table view Delete old managed objects in child MOC Save child MOC Post deletion completion notification Receive deletion completion notification Save parent MOC Once the AFNetworking completion block is triggered when the JSON data has arrived, a nested NSManagedObjectContext is created and passed to an "importer" object that parses the JSON data and saves the objects to the Core Data store. The importer executes using the new performBlock method introduced in iOS 5: NSManagedObjectContext *child = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType]; [child setParentContext:self.managedObjectContext]; [child performBlock:^{ // Create importer instance, passing it the child MOC... }]; The importer object observes its own MOC's NSManagedObjectContextDidSaveNotification and then posts its own notification which is observed by the detail table view controller. When this notification is posted the table view controller performs a save on its own (parent) MOC. I use the same basic pattern with a "deleter" object for deleting the old data after the new data for the day has been imported. This occurs asynchronously after the new data has been fetched by the fetched results controller and the detail table view has been reloaded. One thing I am not doing is observing any merge notifications or locking any of the managed object contexts or the persistent store coordinator. Is this something I should be doing? I'm a bit unsure how to architect this all correctly so would appreciate any advice.

  • Recommendations for C# controls that can be used to create a hierarchical list of prioritised items?

    - by Mendokusai
    I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Anyone got any recommendations for controls for me to look at?

  • Open Safari from within Opera Mini on the iPhone

    - by Ican Zilb
    Now that Opera Mini is becoming so popular in the App store I want to effectively warn my web site visitors that the rendition they see in Opera Mini is far from what I meant them to see and redirect them to my page in Mobile Safari, so they can enjoy HTML5 and CSS3. I've been banging my head around that task all day long, but I can't seem to find a solution. My hope lies in the custom URL schemes, but seems Opera Mini handles all schemes which usually Safari does. Would be great if there's a scheme like safari://www.domain.com which opens ONLY in Safari, so I can redirect the visitors to it. Does anybody know a solution to that problem? --edit Just to make myself clear - browser detection is not the problem (I'm doing Javascript for 13 years now) the question is if there's a way to invoke the Safari app on the iPhone from within a web page which is being viewed in Opera Mini.

  • There is a problem with the Office database

    After a TimeMachine restore; office 2011 is having kittens over permissions it would seem. Having attempted a 'repair' out of Disk Utility, am still seeing: 'there is a problem with the Office database' upon startup. After which Word/Excel work without issues. Outlook on the other hand won't even start. Given the obvious message here "You do not have write access to the Outlook application folder" - where is the DB located to check?! Ideas ? Thank you

  • Silverlight Calling an HttpHandler

    - by Jason N. Gaylord
    I have a Silverlight application that I'm trying to get to invoke an HttpHandler by using WebClient. I have the HttpHandler just sending an email that says test when invoked. If I hit it via a browser, I get the email. However, using a WebClient object with a delegate, I can't seem to get it to connect. I'm going to try a plain old WinForms app to test my code out later this evening, but wasn't sure if I was missing something in my Silverlight app. Any ideas?

  • Recover an accidentaly closed Opera window after restarting Opera?

    - by Kostas
    Hello there and thanks for all the help! I accidentaly closed a window with multiple tabs in Opera. There was another window with a couple of tabs running. I have closed and restarted Opera in the hope it will retrieve the windows at startup (it usually asks if I want to continue from last time). Is there a way I can retrieve my closed window with all the tabs? I cannot see them in the history either, probably because When I switched-on my PC the Internet connection was down and the pages didn't load :-/

  • Getting rid of GNU Emacs's menu bar in terminal windows

    - by Ernest A
    How to get rid of Emacs's menu bar in terminal windows? The standard answer is to put (when (not (display-graphic-p)) (menu-bar-mode -1)) in init.el. However, this solution is not good, because all it does is remove the menu bar after the fact. You can still see it for a split second. It's very annoying. Looking at the source code in startup.el I don't see an obvious solution to this problem. I think the only way is to use before-init-hook. Maybe this could do the trick? (add-hook 'before-init-hook (lambda () (setq emacs-basic-display t))) But this hook is run before init.el and other init files are evaluated, so how is one supposed to use it?

  • Recreating iPhone stock application with nested views

    - by john
    I am trying to create an app similar to the Yahoo Stocks app that comes on the iPhone, with the split-screen interface (table on the top, graph on the bottom). I'm struggling with the view hierarchy. What is the easiest way to implement a split-screen type of application. I basically want two views nested in a parent view. My problem is a little bit more complex because I want functionality like having a uipagecontrol (does this require another viewcontroller, or is simply implemented in the initial view controller)? To what degree do I need to use IB? I would prefer to do this all in Xcode. Thanks in advance!

  • Is is possible to make a shaped, alpha-blended dialog?

    - by jgaa
    I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?
