  • Salt question - using a "random salt"

    - by barfoon
    Hey everyone, Further to my question here, I have another question regarding salts. When someone says "use a random salt" to pre/append to a password, does this mean: Creating a static a 1 time randomly generated string of characters, or Creating a string of characters that changes at random every time a password is created? If the salt is random for every user and stored along with the hashed password, how is the original salt ever retrieved back for verification? Thanks!

  • When should a member function have a const qualifier and when shouldn't it?

    - by SCFrench
    About six years ago, a software engineer named Harri Porten wrote this article, asking the question, "When should a member function have a const qualifier and when shouldn't it?" I found it to be the best write-up I could find of the issue, which I've been wrestling with more recently and which I think is not well covered in most discussions I've found on const correctness. Since a software information-sharing site as powerful as SO didn't exist back then, I'd like to resurrect the question here.

  • Free image uploader with CKEditor

    - by Zakaria
    Hi everybody, I'm using CKEditor to allow the users sending nice rich texts. The problem is that, with the very new version, we must couple it with CKFinder (which requires a license key if deployed) to allow the users "exploring the server" or downloading the images. Is there another free plugin than CKFinder? Should I go back to the FCKEditor rather than the CKEditor? Thank you, Regards.

  • Need to set cursor position to the end of a contentEditable div, issue with selection and range obje

    - by DavidR
    I'm forgetting about cross-browser compatibility for the moment, I just want this to work. What I'm doing is trying to modify a script (and you probably don't need to know this) located at typegreek.com The basic script is found here. Basically what it does is when you type in characters, it converts the character your are typing into greek characters and prints it onto the screen. What I'm trying to do is to get it to work on contentEditable div's (It only works for Textareas) My issue is with this one function: The user types a key, it get's converted to a greek key, and goes to a function, it gets sorted through some if's, and where it ends up is where I can add div support. Here is what I have so far, myField is the div, myValue is the greek character. //Get selection object... var userSelection if (window.getSelection) {userSelection = window.getSelection();} else if (document.selection) {userSelection = document.selection.createRange();} //Now get the cursor position information... var startPos = userSelection.anchorOffset; var endPos = userSelection.focusOffset; var cursorPos = endPos; //Needed later when reinserting the cursor... var rangeObj = userSelection.getRangeAt(0) var container = rangeObj.startContainer //Now take the content from pos 0 -> cursor, add in myValue, then insert everything after myValue to the end of the line. myField.textContent = myField.textContent.substring(0, startPos) + myValue + myField.textContent.substring(endPos, myField.textContent.length); //Now the issue is, this updates the string, and returns the cursor to the beginning of the div. //so that at the next keypress, the character is inserted into the beginning of the div. //So we need to reinsert the cursor where it was. //Re-evaluate the cursor position, taking into account the added character. var cursorPos = endPos + myValue.length; //Set the caracter position. rangeObj.setStart(container,cursorPos) Now, this works only as long as I don't type more than the size of the original text. Say I had 30 characters in the div before hand. If I type more than that 30, it adds character 31, but places the cursor back at 30. I can type character 32 at pos.31, then character 33 at pos.32, but if I try to put character 34 in, it adds the character, and sets the cursor back at 32. The issue is that the function for adding the new character screws up if cursorPos is greater than what is defined in the range. Any ideas?

  • OSGI classcast exception on felix

    - by Nico
    Hi, i'm fairly new to osgi and am trying to get a functional proof of concept together. The setup is that my common api is created in a bundle creatively named common-api.jar with no bundle activator, but it exports all it's interfaces. the one of interest in this situation is DatabaseService.java. I then have a Second bundle called systemx-database-service. That implements the database service interface. this works fine as in the activator of the implementation bundle i test the connection to the database and select some arbitraty values. I also register the service i want to be available to the other bundle's like so: context.registerService(DatabaseService.class.getName(), new SystemDatabaseServiceImpl(context), new Properties()); The basic idea being when you look for a service reference for a Database service you'll get back the SystemDatabaseService implementation. When i do a inspect service the output it this: -> inspect s c 69 System Database Service (69) provides services: ---------------------------------------------- objectClass = za.co.xxx.xxx.common.api.DatabaseService service.id = 39 which would lead me to believe that if i do this in a test bundle: context.getService(context.getServiceReference(DatabaseService.class)); i should get back an instance of DatabaseService.class, but alas no such luck. it simply seems like it cannot find the service. stick with me here my story gets stranger. figuring there is no where to go but up i wrote this monstrosity: for (Bundle bundle : bundles) { if (bundle.getSymbolicName().equals("za.co.xxx.xxx.database-service")) { ServiceReference[] registeredServices = bundle.getRegisteredServices(); for (ServiceReference ref : registeredServices) { DatabaseService service = (DatabaseService) context.getService(ref); // use service here. } } } } now i can actually see the service reference, but i get this error java.lang.ClassCastException: za.co.xxx.xxx.database.service.impl.SystemDatabaseServiceImpl cannot be cast to za.co.xxx.xx.common.api.DatabaseService which is crazy since the implementation clearly implements the interface! Any help would be appreciated. Please keep in mind i'm very new at the osgi way of thinking so my whole approach here might be flawed. oh. if anyone wants the manifests i can post them. and i'm using the maven-bnd-plugin to build and executing on felix. thanks Nico

  • Bounced email on Google App Engine

    - by Ivan Vovnenko
    I'm developing application for google app engine (python), witch needs not only to send emails, but also know which ones bounce back. I created special account for my domain [email protected], added it as an app admin and sending messages from it. The problem is (and it was described here http://code.google.com/p/googleappengine/issues/detail?id=1800) - GAE sets the Return-Path to some internal email address, not allowing to receive bounced email messages. Anyone aware of any possible workaround for this? Thanks.

  • Setting style of ContextMenu on subitems

    - by thedesertfox
    I have created a custom style and template for MenuItem and ContextMenu, and for my first level, that works great, but whenever I add a SubMenu item, the style of that ContextMenu reverts back to the default style. How can I make sure that item uses my custom style? I've tried using the <;Style TargetType="ContextMenu" Key="{x:Type ContextMenu}" syntax as well, and it doesn't seem to be overriding it either.

  • Confused as to how to validate spring mvc form, what are my options?

    - by Blankman
    Latest spring mvc, using freemarker. Hoping someone could tell me what my options are in terms of validating a form with spring mvc, and what the recommend way would be to do this. I have a form that doesn't map directly to a model, it has input fields that when posted, will be used to initialze 2 model objects which I will then need to validate, and if they pass I will save them. If they fail, I want to return back to the form, pre-fill the values with what the user entered and display the error messages. I have read here and there about 2 methods, once of which I have done and understand how it works: @RequestMapping(...., method = RequestMethod.POST) public ModelAndView myMethod(@Valid MyModel, BindingResult bindingResult) { ModelAndView mav = new ModelAndView("some/view"); mav.addObject("mymodel", myModel); if(bindingResult.hasErrors()) { return mav; } } Now this worked if my form mapped directly to the form, but in my situation I have: form fields that don't map to any specific model, they have a few properties from 2 models. before validation occurrs, I need to create the 2 models manually, set the values from the values from the form, and manually set some properties also: Call validate on both models (model1, model2), and append these error messages to the errors collection which I need to pass back to the same view page if things don't work. when the form posts, I have to do some database calls, and based on those results may need to add additional messages to the errors collection Can someone tell me how to do this sort of validation? Pseudo code below: Model1 model1 = new Model1(); Model2 model2 = new Model2(); // manually or somehow automatically set the posted form values to model1 and model2. // set some fields manually, not from posted form model1.setProperty10(GlobalSettings.getDefaultProperty10()); model2.setProperty11(GlobalSettings.getDefaultProperty11()); // db calls, if they fail, add to errors collection if(bindingResult.hasErrors()) { return mav; } // validation passed, save Model1Service.save(model1); Model2Service.save(model2); redirect to another view Update I have using the JSR 303 annotations on my models right now, and it would great if I can use those still. Update II Please read the bounty description below for a summary of what I am looking for.

  • Reset element color to default stylesheet color (Jquery, Javascript)

    - by leaf dev
    I need to be able to reset an input field back to its original color after it has been possibly changed via javascript to a different value. The problem is I do not want to hard code the value obviously in case the stylesheet changes. I would like to use the default color used on the page. Is resetting the color like this fine, or is there a better way to do this? $('#theinput').css('color', '');

  • Method overriding

    - by Gandalf StormCrow
    Can you override method in java without using annotations? Because eclipse doesn't support it if you use JRE6, you need to switch back to 5 to use @Override annotation. Will this method be overriden if I remove the annotation? @Override public String toString() { return name + " [" + genre + "]"; }

  • why is my emacs yanking the wrong text?

    - by Josh Knox
    running emacs 22... on ubuntu 9.04, fresh install. When I copy a region of text via C-w (clipboard-kill-ring-save) then yank it back with C-y (clipboard-yank) it pastes random stuff, from some other buffer that isn't even open. It was working fine earlier today and I haven't changed my emacs config. Any ideas why this is suddenly happening/ how to fix it? Thanks!
