• How does the Trash Can work, and where can I find official documentation, reference, or specification for it?

  - by MestreLion

  When trying to manage trash can from mounted NTFS volumes, I ended up reading FreeDesktop.org's reference on it. Poking around and doing some tests, I realized Ubuntu/Gnome does not follow the specs 100%. Here's why: For non-/ partitions, it always uses <driveroot>/.Trash-<uid>, It never used <driveroot>/.Trash/<uid>, even when i created it in advance. While this works, it's annoying: if I have 15 users, I end up with 15 /.Trash-xxx folders in my drive, while the other approach would still give a single folder (with 15 sub-folders). That "pollution" in my drives is very unpleasant. And specs say "If an $topdir/.Trash directory is absent, an $topdir/.Trash-$uid directory is to be used". Well, it IS present, so why does it never use it? root trash does not work, at least not out of the box. Open nautilus as root and click on trash; it gives an error. Try to delete any file, it says "it can't move to trash". Ok, I know this can be fixed by creating /root/.local/share. But specs says "A “home trash” directory SHOULD be automatically created for any new user. If this directory is needed for a trashing operation but does not exist, the implementation SHOULD automatically create it, without any warnings or delays.". Why the error then? Bug? Why must I change /etc/fstab entries for mounted volumes, adding options like uid and guid, if the volumes are already mounted as RW for everyone? These are just some examples of deviation from the standard. So, the question is: "If Ubuntu does not adhere 100% to the spec, HOW exactly does the trash work? WHERE can i find a technical reference for Ubuntu's implementation of the trash?" By the way: if Ubuntu does happen to follow specs, please tell me what I am doing wrong, especially regarding the /.Trash-<uid> vs /.Trash/<uid> issue. Thanks! EDIT: Some more info: If a given fs has no support for the sticky bit (VFAT, NTFS), it probably doesn't have for permissions either (at least VFAT surely doesn't). So what prevents one user from purging / restoring other users' ./Trash-xxx ? If one can read/write his own Trash, one can do the same for the whole drive, including other's trashes, correct? Or does Gnome have some kind of "extra" protection on ./Trash-xxx folders on VFAT/NTFS fs? If Linux can "emulate" file permissions on NTFS mounting by editing /fstab uid and gid options, can it also "emulate" the sticky bit? I would really prefer to use /.Trash/xxx format... For the root issue: for the / partition, I can use trash as root, and it goes to /root/.local/shate/Trash. But if I click on Nautilus "Trash" (as root), I get an error. Don't you? So files are correctly trashed, but I can't access it. All I can do is manually "purge" them (by deleting files on /root/.local/shate/Trash), but restoring would be very tricky (opening info files and manually moving, etc.). For non-/ partitions (or at least for VFAT/NTFS), I can not even use trash as root: it does not create a ./Trash-0 folder, it simply says "Cannot trash, want to permanently delete?" Why? About fstab: i use it for a permanent mount for my NTFS partitions. I have several, and if not "pre-mounted" they really clutter the desktop and/or Nautilus. I'd rather have it pre-mounted, integrated in my fs, in mounts like /data , /windows/xp , /windows/vista , and so on, and leave /media and its "mount/unmount" flexibility just for truly removable drives. So, if Ubuntu/Gnome truly follows the spec, is there any way to fix the root issues and to "emulate" the sticky bit for (at least) my fstab'ed NTFS fixed partitions?

• How to find hidden/cloak files in Windows 2003?

  - by homemdelata

  Here is the point. I set Windows to display all the hidden files and protected operating system files but even after that, my antivirus (Kaspersky) is still getting a ".dll" file on "c:\windows\system32" saying it's a riskware 'Hidden.Object'. I tried to find this file everytime but it's not there. So I asked one of the developers to create a service that verifies the folder each 5 seconds and, if it founds the file, copies to another place. If it copies to another place with the same name and extension, I still can't find the file on the other folder but Kaspersky now founds both. If I keep the same name but with a different extension, like ".temp123", I still can't find the file. Lastly, I created an empty text file and renamed with the same name as the other one, the file just gone too. After all this research It's clear that every file with this same name on this specific server gets cloak, doesn't matter the file extension. I created a file with this same name on another server and nothing happens, the file is still there without problem. How can I found this kind of file? How can I "uncloak" it? How can I know what this file is doing?

• A Custom View Engine with Dynamic View Location

  - by imran_ku07

      Introduction:          One of the nice feature of ASP.NET MVC framework is its pluggability. This means you can completely replace the default view engine(s) with a custom one. One of the reason for using a custom view engine is to change the default views location and sometimes you need to change the views location at run-time. For doing this, you can extend the default view engine(s) and then change the default views location variables at run-time.  But, you cannot directly change the default views location variables at run-time because they are static and shared among all requests. In this article, I will show you how you can dynamically change the views location without changing the default views location variables at run-time.       Description:           Let's say you need to synchronize the views location with controller name and controller namespace. So, instead of searching to the default views location(Views/ControllerName/ViewName) to locate views, this(these) custom view engine(s) will search in the Views/ControllerNameSpace/ControllerName/ViewName folder to locate views.           First of all create a sample ASP.NET MVC 3 application and then add these custom view engines to your application,   public class MyRazorViewEngine : RazorViewEngine { public MyRazorViewEngine() : base() { AreaViewLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.cshtml", "~/Areas/{2}/Views/%1/{1}/{0}.vbhtml", "~/Areas/{2}/Views/%1/Shared/{0}.cshtml", "~/Areas/{2}/Views/%1/Shared/{0}.vbhtml" }; AreaMasterLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.cshtml", "~/Areas/{2}/Views/%1/{1}/{0}.vbhtml", "~/Areas/{2}/Views/%1/Shared/{0}.cshtml", "~/Areas/{2}/Views/%1/Shared/{0}.vbhtml" }; AreaPartialViewLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.cshtml", "~/Areas/{2}/Views/%1/{1}/{0}.vbhtml", "~/Areas/{2}/Views/%1/Shared/{0}.cshtml", "~/Areas/{2}/Views/%1/Shared/{0}.vbhtml" }; ViewLocationFormats = new[] { "~/Views/%1/{1}/{0}.cshtml", "~/Views/%1/{1}/{0}.vbhtml", "~/Views/%1/Shared/{0}.cshtml", "~/Views/%1/Shared/{0}.vbhtml" }; MasterLocationFormats = new[] { "~/Views/%1/{1}/{0}.cshtml", "~/Views/%1/{1}/{0}.vbhtml", "~/Views/%1/Shared/{0}.cshtml", "~/Views/%1/Shared/{0}.vbhtml" }; PartialViewLocationFormats = new[] { "~/Views/%1/{1}/{0}.cshtml", "~/Views/%1/{1}/{0}.vbhtml", "~/Views/%1/Shared/{0}.cshtml", "~/Views/%1/Shared/{0}.vbhtml" }; } protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreatePartialView(controllerContext, partialPath.Replace("%1", nameSpace)); } protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreateView(controllerContext, viewPath.Replace("%1", nameSpace), masterPath.Replace("%1", nameSpace)); } protected override bool FileExists(ControllerContext controllerContext, string virtualPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.FileExists(controllerContext, virtualPath.Replace("%1", nameSpace)); } } public class MyWebFormViewEngine : WebFormViewEngine { public MyWebFormViewEngine() : base() { MasterLocationFormats = new[] { "~/Views/%1/{1}/{0}.master", "~/Views/%1/Shared/{0}.master" }; AreaMasterLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.master", "~/Areas/{2}/Views/%1/Shared/{0}.master", }; ViewLocationFormats = new[] { "~/Views/%1/{1}/{0}.aspx", "~/Views/%1/{1}/{0}.ascx", "~/Views/%1/Shared/{0}.aspx", "~/Views/%1/Shared/{0}.ascx" }; AreaViewLocationFormats = new[] { "~/Areas/{2}/Views/%1/{1}/{0}.aspx", "~/Areas/{2}/Views/%1/{1}/{0}.ascx", "~/Areas/{2}/Views/%1/Shared/{0}.aspx", "~/Areas/{2}/Views/%1/Shared/{0}.ascx", }; PartialViewLocationFormats = ViewLocationFormats; AreaPartialViewLocationFormats = AreaViewLocationFormats; } protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreatePartialView(controllerContext, partialPath.Replace("%1", nameSpace)); } protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.CreateView(controllerContext, viewPath.Replace("%1", nameSpace), masterPath.Replace("%1", nameSpace)); } protected override bool FileExists(ControllerContext controllerContext, string virtualPath) { var nameSpace = controllerContext.Controller.GetType().Namespace; return base.FileExists(controllerContext, virtualPath.Replace("%1", nameSpace)); } }             Here, I am extending the RazorViewEngine and WebFormViewEngine class and then appending /%1 in each views location variable, so that we can replace /%1 at run-time. I am also overriding the FileExists, CreateView and CreatePartialView methods. In each of these method implementation, I am replacing /%1 with controller namespace. Now, just register these view engines in Application_Start method in Global.asax.cs file,   protected void Application_Start() { ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new MyRazorViewEngine()); ViewEngines.Engines.Add(new MyWebFormViewEngine()); ................................................ ................................................ }             Now just create a controller and put this controller's view inside Views/ControllerNameSpace/ControllerName folder and then run this application. You will find that everything works just fine.       Summary:          ASP.NET MVC uses convention over configuration to locate views. For many applications this convention to locate views is acceptable. But sometimes you may need to locate views at run-time. In this article, I showed you how you can dynamically locate your views by using a custom view engine. I am also attaching a sample application. Hopefully you will enjoy this article too.

• How to find the reason for a weekly downtime on an Ubuntu web server hosted by AWS?

  - by IceSheep

  We started monitoring our web server using Pingdom and found out that we have a downtime of a few minutes every Sunday at 0:00 UTC. The test runs every minute and checks if a successful HTTP response (code 200) is returned on port 80. The test fails due to a timeout (no response after 30 seconds). Here's what we've already checked – without success: Since we run our webserver behind a load balancer, I've set the Pingdom test on the load balancer's public DNS and the webserver's public DNS in order to find out if there's a problem with the AWS load balancer – both tests return the same result We set up Munin on our webserver. Everything looked fine even after the failure. Since the last failure lasted only 2 minutes I suppose Munin couldn't capture a potential problem (it only checks every 5 minutes) I have checked /var/log/apache2/error.log and /var/log/syslog for suspicious entries I have checked /etc/cron.weekly and /etc/crontab for suspicious entries I have searched for files created or last-modified during 0:00 and 0:15 using this method: touch -t 201209020000 start touch -t 201209020015 end find / -newer start -and ! -newer end (nothing found) Has anybody experienced a similar problem? Any proposals on how to find the reason for this behavior? It's Ubuntu 10.04 LTS running on an AWS m1.large instance. Thanks!

• HttpWebResponse with MJPEG and multipart/x-mixed-replace; boundary=--myboundary response content typ

  - by arri.me

  I have an ASP.NET application that I need to show a video feed from a security camera. The video feed has a content type of 'multipart/x-mixed-replace; boundary=--myboundary' with the image data between the boundaries. I need assistance with passing that stream of data through to my page so that the client side plugin I have can consume the stream just as it would if I browsed to the camera's web interface directly. The following code does not work: //Get response data byte[] data = HtmlParser.GetByteArrayFromStream(response.GetResponseStream()); if (data != null) { HttpContext.Current.Response.OutputStream.Write(data, 0, data.Length); } return;

• How can I replace this semaphore with a monitor?

  - by Kurru

  Hi In previous question of mine, someone had meantioned that using Semaphores were expensive in C# compared to using a monitor. So I ask this, how can I replace the semaphore in this code with a monitor? I need function1 to return its value after function2 (in a separate thread) has been completed. I had replaced the Semaphore.WaitOne with a Monitor.Wait and the Semaphore.Release with a Monitor.PulseAll but the PulseAll was being triggered before the Wait causing the program to hang. Any idea how to avoid that race condition? Semaphore semaphore = new Semaphore(0,1); byte b; public byte Function1() { // new thread starting in Function2; semaphore.WaitOne(); return b; } public void Function2() { // do some thing b = 0; semaphore.Release(); }

• How to do regex HTML tag replace in SQL Server?

  - by timmerk

  I have a table in SQL Server 2005 with hundreds of rows with HTML content. Some of the content has HTML like: <span class=heading-2>Directions</span> where "Directions" changes depending on page name. I need to change all the <span class=heading-2> and </span> tags to <h2> and </h2> tags. I wrote this query to do content changes in the past, but it doesn't work for my current problem because of the ending HTML tag: Update ContentManager Set ContentManager.Content = replace(Cast(ContentManager.Content AS NVARCHAR(Max)), 'old text', 'new text') Does anyone know how I could accomplish the span to h2 replacing purely in T-SQL? Everything I found showed I would have to do CLR integration. Thanks!

• Is there a way to replace the Eclipse JDT's code completion list with a multi-level tree?

  - by Uri

  I know that the eclipse code completion widget can be customized to add new suggestions and even to change the order. I'm wondering whether there's a way to replace the current list format (or single-level tree, if this is a tree control) with a tree of multiple levels. Thus, for example, instead of selecting from a list of methods sorted by name, I will select from a category and then from a subcategory, and then from the items. I'm not too familiar with that part of the SDK, but I'd like to know if this is feasible. Thanks!

• How can I pop a view from a UINavigationController and replace it with another in one operation?

  - by Matt Brandt

  I have an application where I need to remove one view from the stack of a UINavigationController and replace it with another. The situation is that the first view creates an editable item and then replaces itself with an editor for the item. When I do the obvious solution within the first view: MyEditViewController *mevc = [[MYEditViewController alloc] initWithGizmo: gizmo]; [self retain]; [self.navigationController popViewControllerAnimated: NO]; [self.navigationController pushViewController: mevc animated: YES]; [self release]; I get very strange behavior. Usually the editor view will appear, but if I try to use the back button on the nav bar I get extra screens, some blank, and some just screwed up. The title becomes random too. It is like the nav stack is completely hosed. What would be a better approach to this problem? Thanks, Matt

• Should I replace string patterns in asp.net mvc using a custom viewengine?

  - by Roger Rogers

  Have an ASP.NET MVC site that is localized. The localization functionality adds the two digit language ID to the URL, e.g. /es/Page. If no language Id is found in the URL, the site switches to the user's browser culture. All's good. However, the site's hyperlinks, a mixture of hard-coded href tags, actionlinks, etc., don't include the base language ID, so when clicking through the site the set culture is lost, and the site reverts to the user's browser culture. My (lazy) thought is to replace all href values, that don't point to an external site, with the localized URL (e.g. include the /es/). Otherwise, all site links will need to be updated to include the culture code. Is this just plain dumb? Or, reasonable, and should be done using a custom view engine, or some other approach?

• Simplest solution to replace a tiny file inside an MSI?

  - by sascha

  Many of our customers have access to InstallShield, WISE or AdminStudio. These aren't a problem. I'm hoping there is some way I can provide our smaller customers without access to commercial repackaging tools a freely available set of tools and steps to do the file replacement themselves. Only need to replace a single configuration file inside a compressed MSI, the target user can be assumed to already have Orca installed, know how to use this to customize the Property table (to embed license details for GPO deployment) and have generated an MST file. Disclaimer: this is very similar to another question but both questions and answers in that thread are not clear.

• Is it possible to replace the system open file dialog?

  - by Edwin

  I want to replace the standard system open file dialog with the one I wrote, that means no matter within which programs you are opening a file, my dialog will be shown instead of the standard one, is this possible? It seems that that there is no such API provided to accomplish this, is it possible to use some hooking technique, but this has to be reliable and not to be treated as spyware by anti-virus tools? any other options? If this is not possible, is it possible to add to the spacebar or toolbar in the standard open file dialog a button which invokes my dialog, which allow users select a file and in turn returns the path of the selected file to the "File name" input box of the standard dialog? Any hits, links and code examples will be appreciated.

• How can I replace only the last occurence of an number in a string with php?

  - by Shawn

  How would you change this: a-10-b-19-c into something like this: a-10-b-20-c using regular expressions in PHP? The only solution I've found so far is: reverse the original string - "c-91-b-01-a" find the first number - "91" reverse it - "19" turn in into a number (parseInt) - 19 add 1 to it (+1) - 20 turn it into a string again (toString) - "20" reverse it again - "02" replace the original match with this new number - "c-02-b-01-a" reverse the string - "a-10-b-20-c" I was hoping someone on SO would have a simpler way to do this... Anyone?

• How to replace 'dash' with 'underscore' in an IIRF rule?

  - by jessegavin

  I have a web app which serves images based on the subdomain. We wanted to provide our users with a url like this: http://{username}.domain.com/images/myimage.jpg Instead of what we used to have: http://www.reallylongdomainname.com/users/{username}/images/myimage.jpg This makes the url shorter and less 'snoopable'. So I set up an IIRF .ini file to do some url rewriting and it works great except for the fact that some of our users folders have an underscore. And from what I've read, underscore is not a valid character in a domain name (even though IIS supports it). I want to know how I could do a find and replace in the $1 back reference so that a url like this: http://some-user.domain.com/... Could be rewritten to this: /users/some_user/.. Here's my IIRF rule. RewriteCond %{HTTP_HOST} ^(?!www)([^\.]+)\.domain\.com RewriteRule ^/(.*)$ /users/*1/$1 [L,I] Thanks for any help.

• Replace a word in an XML file through StreamReader in XNA?

  - by kcoppock

  Okay, so this is sort of a hack...but it may have to be. I'm writing an app in XNA, which from my research into this problem apparently doesn't support XML version 1.1. I'm reading in the contents of an ePub document, and one of the newer books contains its content directory as a version 1.1 XML document. This causes my program to crash. However, the structure is the same as the rest, the only thing that should be keeping it from working is the hard-coded "1.0" in the XmlDocument class. Is it possible that I could read in the file from the stream, see if it contains: <?xml version="1.1" encoding="UTF-8" standalone="no"?> and simply replace it with "1.0"? Then I could pull it in as an XmlDocument. I'm not doing any writing to the file, or any complex structural reading, just looking for a few specific nodes, and pulling in the values, so I don't know what the ramifications of this would be.

• How to replace master branch in git, entirely, from another branch?

  - by Jason

  Hi, I have two branch in my git repo: master seotweaks (created originally from master) I created "seotweaks" with the intention of quickly merging it back into master, however that was 3 months ago and the code in this branch is 13 versions ahead of "master", it has effectively become our working master branch as all the code in "master" is more or less obsolete now. Very bad practice I know, lesson learnt. Do you know how I can replace all of the contents of the "master" branch with those in "seotweaks"? I could just delete everything in "master" and merge, but this does not feel like best practice.

The second file gr1.xml contains something like this: <item name="i1">Item one</item> <item name="i2">Item two</item> <item name="i3">Item three</item> Note that there is no XML declaration in gr1.xml, just plain items without single parent node. So… Which is the best way to replace <group/> with its <item/>s? I have already tried some things like manual enclosing of gr1.xml content into a single node with XML declaration and loading it into XmlDocument, but it doesn't look like a good solution.

  I am sanitizing an input field and manually getting and setting the caret position in the process. With some abstraction, here's the basic idea: <input type="text" onkeyup"check(this)"> And javascript... function check(element) { var charPosition = getCaretPosition(element); $(element).val( sanitize( $(element).val() ) ); setCaretPosition(element, charPosition); } function sanitize(s) { return s.replace(/[^a-zA-Z0-9\s]/g, ''); } This is working fine except when a character does actually get sanitized, my caret position is off by one. Basically I'd like a way to see if the sanitize function has actually replaced a character (and at what index) so then I can adjust the charPosition if necessary. Any ideas?
