  • List of free hosted domains (phishing prevention)

    - by nigative
    Does anyone has a compiled list of free hosting domains? On the website, when user clicks on external link I want them to be redirected to my page that will check if that external link is on free hosting or not. If it is, I want to warn the user, but right now I can't find a list of such domains. Any help?

  • Checking if a directory contains files

    - by ionn
    How do I check if a directory contains files? Something similar to this: if [ -e /some/dir/* ]; then echo "huzzah"; fi; but which works if the directory contains one or several files (the above one only works with exactly 0 or 1 files).

  • Best way to detect duplicates when using Spring Hibernate Template

    - by Dean Povey
    We have an application which needs to detect duplicates in certain fields on create. We are using Hibernate as our persistence layer and using Spring's HibernateTemplate. My question is whether it is better to do so an upfront lookup for the item before creating, or to attempt to catch the DataIntegrityViolation exception and then check if this is caused by a duplicate entry.

    - by Ahmad Fouad
    Hello, I have pagination links set-up like this: http://localhost/?page=2 http://localhost/?page=3 They are wrapped in Anchor links as the HREF attribute. I want to know how can I check first if the HREF attribute for a given ANCHOR contains the query string "page" case sensitive, and if it exists return its number the value after page= Please give me a straightforward example on this, much appreciated. :)

  • How to perform duplicate key validation using entlib (or DataAnnotations), MVC, and Repository pattern

    - by olivehour
    I have a set of ASP.NET 4 projects that culminate in an MVC (3 RC2) app. The solution uses Unity and EntLib Validation for cross-cutting dependency injection and validation. Both are working great for injecting repository and service layer implementations. However, I can't figure out how to do duplicate key validation. For example, when a user registers, we want to make sure they don't pick a UserID that someone else is already using. For this type of validation, the validating object must have a repository reference... or some other way to get an IQueryable / IEnumerable reference to check against other rows already in the DB. What I have is a UserMetadata class that has all of the property setters and getters for a user, along with all of the appropriate DataAnnotations and EntLib Validation attributes. There is also a UserEntity class implemented using EF4 POCO Entity Generator templates. The UserEntity depends on UserMetadata, because it has a MetadataTypeAttribute. I also have a UserViewModel class that has the same exact MetadataType attribute. This way, I can apply the same validation rules, via attributes, to both the entity and viewmodel. There are no concrete references to the Repository classes whatsoever. All repositories are injected using Unity. There is also a service layer that gets dependency injection. In the MVC project, service layer implementation classes are injected into the Controller classes (the controller classes only contain service layer interface references). Unity then injects the Repository implementations into the service layer classes (service classes also only contain interface references). I've experimented with the DataAnnotations CustomValidationAttribute in the metadata class. The problem with this is the validation method must be static, and the method cannot instantiate a repository implementation directly. My repository interface is IRepository, and I have only one single repository implementation class defined as EntityRepository for all domain objects. To instantiate a repository explicitly I would need to say new EntityRepository(), which would result in a circular dependency graph: UserMetadata [depends on] DuplicateUserIDValidator [depends on] UserEntity [depends on] UserMetadata. I've also tried creating a custom EntLib Validator along with a custom validation attribute. Here I don't have the same problem with a static method. I think I could get this to work if I could just figure out how to make Unity inject my EntityRepository into the validator class... which I can't. Right now, all of the validation code is in my Metadata class library, since that's where the custom validation attribute would go. Any ideas on how to perform validations that need to check against the current repository state? Can Unity be used to inject a dependency into a lower-layer class library?

  • mounting ext4 fs with block size of 65536

    - by seaquest
    I am doing some benchmarking on EXT4 performance on Compact Flash media. I have created an ext4 fs with block size of 65536. however I can not mount it on ubuntu-10.10-netbook-i386. (it is already mounting ext4 fs with 4096 bytes of block sizes) According to my readings on ext4 it should allow such big block sized fs.

  • Best way for user authentication on JavaEE 6 using JSF 2.0?

    - by ngeek
    I'm wondering what the current state of art recommendation is regarding user authentication for a web application making use of JSF 2.0 (and if any components do exist) and JEE6 core mechanisms (login/check permissions/logouts) with user information hold in a JPA entity. The Sun tutorial is a bit sparse on this (only handles servlets). This is without making use of a whole other framework, like Spring-Security (acegi), or Seam, but trying to stick hopefully with the new Java EE 6 platform (web profile) if possible. Thanks, Niko

  • Javascript regex returning true.. then false.. then true.. etc

    - by betamax
    I have a strange problem with the validation I am writing on a form. It is a 'Check Username' button next to an input. The input default value is the username for example 'betamax'. When I press 'Check Username' it passes the regex and sends the username to the server. The server behaves as expected and returns '2' to tell the javascript that they are submitting their own username. Then, when I click the button again, the regex fails. Nothing is sent to the server obviously because the regex has failed. If I press the button again, the regex passes and then the username is sent to the server. I literally cannot figure out what would be making it do this! It makes no sense to me! This is my code: $j("#username-search").click(checkUserName); function checkUserName() { var userName = $j("#username").val(); var invalidUserMsg = 'Invalid username (a-zA-Z0-9 _ - and not - or _ at beginning or end of string)'; var filter = /^[^-_]([a-z0-9-_]{4,20})[^-_]$/gi; if (filter.test(userName)) { console.log("Pass") $j.post( "/account/profile/username_check/", { q: userName }, function(data){ if(data == 0) { $j("#username-search-results").html("Error searching for username. Try again?"); } else if(data == 5) { $j("#username-search-results").html(invalidUserMsg); } else if(data == 4) { $j("#username-search-results").html("Username too short or too long."); } else if(data == 2) { $j("#username-search-results").html("This is already your username."); } else if(data == 3) { $j("#username-search-results").html("This username is taken."); } else if(data == 1){ $j("#username-search-results").html("This username is available!"); } }); } else { console.log("fail") $j("#username-search-results").html(invalidUserMsg); } return false; } The HTML: <input name="username" id="username" value="{{ user.username }}" /> <input type="button" value="Is it taken?" id="username-search"> <span id="username-search-results"></span>

  • Change MS Access to Exclusive on the fly

    - by Nate
    I have a process in an MS Acess database that the users will usually run once daily, but could be more or less. It takes several minutes and requires temporary exclusive access because it deletes and recreates the main table. I have code to check to see if there are other users in the db before the process starts, but is there a way to change the access to "exclusive" at the beginning, and then change it back to open access at the end? Thanks for any help.
