• Development stopped: Is truecrypt unsecure?

  - by Alex Mantel

  I was looking for truecrypt today and found this: http://truecrypt.sourceforge.net/ The page layout changed and claims "truecrypt is unsecure". Futher: "The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP" My Questions: What are the risks for still using truecrypt? Will there be any fork of truecrypt? Is Windows "BitLocker" trustable? Is the reason why the development stopped reliable? Which independent alternatives are there for Linux, MacOS and Windows?

• What to choose API based server or Socket based server for data driven application

  - by Imdad

  I am working on a project which has a Desktop Application for MAC/COCOA, a native application for iPhone another native application in iPad. All the application do almost same thing. The applications are data driven applications. Every communication to server is made via a restful API developed in PHP. When a user logs in a lot of data is fetched from server. And to remain in sync with server pooling is done. As there are lot of data to pool it makes application slower and un-reliable. A possible solution that comes into my mind is to use Socket based server. My question is that will it reasonably improve the performance? And which technology (of sockets) will be good as a server side solution for data driven application? I have heard a lot about Node.js. Please give your suggestions.

• Recommended book on Actors concurrency model (patterns, pitfalls, etc.)?

  - by Larry OBrien

  The Actors concurrency model is clearly gaining favor. Is there a good book that presents the patterns and pitfalls of the model? I am thinking about something that would discuss, for instance, the problems of consistency and correctness in the context of hundreds or thousands of independent Actors. It would be okay if it were associated with a specific language (erlang, I would imagine, since that seems universally regarded as the proven implementation of Actors), but I am hoping for something more than an introductory chapter or two. (FWIW, I'm actually most interested in Actors as they are implemented in Scala.)

• Test driven development - convince me!

  - by Casebash

  I know some people are massive proponents of test driven development. I have used unit tests in the past, but only to test operations that can be tested easily or which I believe will quite possibly be correct. Complete or near complete code coverage sounds like it would take a lot of time. What projects do you use test-driven development for? Do you only use it for projects above a certain size? Should I be using it or not? Convince me!

• ASP.NET MVC 1: Model Binding With Disabled Textbox

  - by modernzombie

  I have a textbox that I am defining as <%= Html.TextBox("Username", Model.Form.Username, new { @class = "textbox", @disabled = "disabled" })%> In my action [AcceptVerbs(HttpVerbs.Post)] [ValidateAntiForgeryToken] public ActionResult EditLogin(LoginForm post) { ... return View(model); } post.Username will be blank, all other properties bind correctly, but if I change @disabled="disabled to @readonly="readonly" the username binds properly and everything works. It looks like model binding ignores values in disabled fields. Is their a way around this? I still need the field's value to bind to the model. I can use readonly but would prefer to use disabled so it is visually apparent to the user that they cannot edit the value of the field.

• Model validation with enumerable properties in Asp.net MVC2 RTM

  - by Robert Koritnik

  I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

• Model availability inside ActionFilter

  - by Sayed Ibrahim Hashimi

  I have created a new ActionFilter for an ASP.NET MVC application that I'm creating. I have an action which accepts an Http Post and the argument of the action method accepts an object, for which I have created and registered a custom model binder. I noticed that inside the IActionFilter.OnActionExecuting the value for filterContext.Controller.ViewData.Model is always null despite the fact that it looks like the model binder is always invoked before the action filter OnActionExecuting method. In contrast to this inside the IActionFilter.OnActionExecuted method of the same action filter the value for filterContext.Controller.ViewData.Model is not null. Do you guys know if this is by design or a bug? If by design are their any links which describe why this is? Thanks.

• mvc presentation model best-practices

  - by Andrew Florko

  Hello, everybody How do you usually convert business objects to presentation? For example: Business object Person { Id, FirstName, LastName, Patronymic ... } should be presented as "LastName F. P. " in html layout. We use Presentation classes hierarchy to represent data ready for output from Business model. Questions: Will you keep presentation model completely separated from Business Model. For example, can strong-typed views (MVC ASP.NET) aggregate formatted business data as well as raw business objects (that leads toward <%=Html.Encode(PersonHelper.ToShort(Model.Person))% html layout injections) What architecture layer do you choose for conversion (mvc controllers that formats business data from business layer, for instance). Thank you in advance

• Custom Validation Attribute with Custom Model Binder in MVC 2

  - by griegs

  I apologise for the amount of code I have included. I've tried to keep it to a minimum. I'm trying to have a Custom Validator Attribute on my model as well as a Custom Model binder. The Attribute and the Binder work great seperately but if I have both, then the Validation Attribute no longer works. Here is my code snipped for readability. If I leave out the code in global.asax the custom validation fires but not if I have the custom binder enabled. Validation Attribute; public class IsPhoneNumberAttribute : ValidationAttribute { public override bool IsValid(object value) { //do some checking on 'value' here return true; } } Useage of the attribute in my model; [Required(ErrorMessage = "Please provide a contact number")] [IsPhoneNumberAttribute(ErrorMessage = "Not a valid phone number")] public string Phone { get; set; } Custom Model Binder; public class CustomContactUsBinder : DefaultModelBinder { protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) { ContactFormViewModel contactFormViewModel = bindingContext.Model as ContactFormViewModel; if (!String.IsNullOrEmpty(contactFormViewModel.Phone)) if (contactFormViewModel.Phone.Length > 10) bindingContext.ModelState.AddModelError("Phone", "Phone is too long."); } } Global asax; System.Web.Mvc.ModelBinders.Binders[typeof(ContactFormViewModel)] = new CustomContactUsBinder();

• Django anonymous user in model

  - by jack

  I have a model defined as below: class Example(models.Model): user = models.ForeignKey(User, null=True) other = models.CharField(max_length=100) The problem is Django refuses to assign django.contrib.auth.models.AnonymousUser directly to Example.user as null field so everytime I have to check if request.user.is_authenticated() ans assign Example.user = None manually. Is there a default value for AnonymousUser to use in a model field?

• zend framework can't find Model classes ?

  - by user284503

  Yall: I have a simple question, it might be a simple configuration issue, but I have a Model defined, and when I try to access it from a controller it fails. The Model is in the model directory, and when I look at the quickstart app, it seems like this should work. Here is my model: <?php class Application_Model_User { protected $_user; protected $_password; protected $_userId; // very simple right } ?> My controller just stops.. here is the controller code: <?php class UserController extends Zend_Controller_Action { public function init() { } public function indexAction() { // display login form $users = new Application_Model_User(); echo "test never echos.. stopped above ? weird huh.."; // fails before .. } ?> Thank you everyone,

• List of models in Model in MVC

  - by arri

  I have two models: class ModelIn{ public string FirstName { get; set; } public string LastName { get; set; } public string Address { get; set; } } class ModelOut{ public ModelOut(){ People = new List<ModelIn>();} public List<ModelIn> People { get; private set;} public string Country { get; set; } } And I have Controller editing ModelOut: public ActionResult People() { ... return View(SomeModelOutInstanceWith3People); } [HttpPost] public ActionResult(ModelOut m) { ... } In view I have sth like: <% using (Html.BeginForm()) { %> <%: Html.EditorFor(m => Model.Country) %> <% for(int i = 0; i < Model.People.Count; ++i){ %> <%: Html.EditorFor(m => Model.People[i].FirstName) %> <%: Html.EditorFor(m => Model.People[i].LastName) %> <%: Html.EditorFor(m => Model.People[i].Address) %> <% } %> <input type="submit" /> <% } %> It works all OK, but in post action I have empty ModelOut m. I can see in logs that data is sent correctly. I have tried everything, nothing works.

• Alloy MVC Framework Titanium Network (Model)

  - by flyingDuck

  I'm trying to authenticate using the Model in Alloy. I have been trying to figure this problem out since yesterday. If anybody could help me, I'd really appreciate it. So, I have a view login.xml, then a controller login.js. The login.js contains the following function: var user = Alloy.Models.user; //my user.js model function login(e) { if($.username.value !== '' && $.password.value !== ''){ if(user.login($.username.value, $.password.value)){ Alloy.createController('home').getView().open(); $.login.close(); } }else{ alert('Username and/or Password required!'); } } Then in my user.js model, it's like this: extendModel : function(Model) { _.extend(Model.prototype, { login: function(username, password) { var first_name, last_name, email; var _this = this; var url = 'http://myurl.com/test.php'; var auth = Ti.Network.createHTTPClient({ onerror: function(e){ alert(e.error); }, onload: function(){ var json = this.responseText; var response = JSON.parse(json); if(response.logged == true){ first_name = response.f_name; last_name = response.l_name; email = response.email; _this.set({ loggedIn: 1, username: email, realname: first_name + ' ' + last_name, email: email, }); _this.save(); }else{ alert(response.message); } }, }); auth.open('POST', url); var params = { usernames: username, passwords: password, }; auth.send(params); alert(_this.get('email')); //alert email }, }); When I click on login in login.xml it calls the function login in index.js. So, now my problem is that, when I click the button for the first time, I get an empty alert from alert(_this.get('email')), but then when I click the button the second time, everything works fine, it alerts the email. I have no idea what's going on. Thank you for the help.

• Proper design a Model-Controller in Cocoa?

  - by legege

  Hi, I'm trying to design a simple Cocoa application and I would like to have a clear and easy to understand software architecture. Of course, I'm using a basic MVC design and my question concerns the Model layer. For my application, the Model represents data fetched on the Internet with a XML-RPC API. I'm planning to use Core Data to represent a locally fetched version. How should the data be loaded initially? I'm reading the Cocoa Design Pattern book, and they talk about a Model-Controller that is centric to the Model. How would that be done? Thanks!

• Codeigniter: Check where model is loaded from?

  - by qwerty

  I'm having the strangest thing ever right now. I "disabled" a model because i don't need to access it ever again. I did so by echoing out an error string in the __construct() and right after that die(). That way i would notice if i ever loaded the model, even by mistake, which should never happen. Alright? The problem is, the model is not loaded ANYWHERE in the entire project, but it still gets loaded for some reason. It's not auto loaded, that's for sure. Is it possible to track down where a model is loaded? Like which line it happens etc?

• Implementing a Cakephp Model using an Array

  - by Zubin

  The CakePHP Cookbook states that a Model can use a file (csv for example) instead of an actual database table but I couldn't find any implementation for it. I was wondering if it is possible to use an Array of data as a model in CakePHP since I have a fairly static set of data which is important to me in a relationship with another table but it doesn't make a whole lot of sense to create a complete table for it. Is it possible to implement a CakePHP Model using an Array?

• Error Handling in Model (MVC)

  - by Andre

  I was wondering what the excepted standard is for handling errors in the Model. Currently I have 'setError' and 'getError' methods that's in use by all my Models. This means I'm only concerned with whether a call to a method in my Model is true or false. If it's false then I would use $this-model-getError() in my Controller. Additionally I'm contemplating setting up a separate file that contains all my errors. One file per model, also wanted to have thoughts on this.

• Formating a date field in the Model (Codeigniter)

  - by Landitus

  Hi, I', trying to re-format a date from a table in Codeigniter. The Controller is for a blog. I was succesfull when the date conversion happens in the View. I was hoping to convert the date in the Model to have things in order. This is the Model: class Novedades_model extends Model { function getAll() { $this->db->order_by('date','desc'); $query = $this->db->get('novedades'); if($query->num_rows() > 0) { foreach ($query->result() as $row) { $data[] = $row; } } return $data; } } This is part of the controller $this->load->model('novedades_model'); $data['records'] = $this->novedades_model->getAll(); Here's the date conversion as it happens in the View. This is inside the posts loop: <?php foreach($records as $row) : ?> <?php $fdate = "%d <abbr>%M</abbr> %Y"; $dateConv = mdate($fdate, mysql_to_unix($row->date)); ?> <div class="article section"> <span class="date"><?php echo $dateConv ;?></span> ... Keeps going ... How can I convert the date in the Model? Can I access the date key and refactor it?

• Test driven vs Business requirements constant changing

  - by James Lin

  One of the new requirement of our dev team set by the CTO/CIO is to become test driven development, however I don't think the rest of the business is going to help because they have no sense of development life cycles, and requirements get changed all the time within a single sprint. Which gets me frustrated about wasting time writing 10 test cases and will become useless tomorrow. We have suggested setting up processes to dodge those requirement changes and educate the business about development life cycles. What if the business fails to get the idea? What would you do?
