  • Do similar passwords have similar hashes?

    - by SLC
    Our computer system at work requires users to change their password every few weeks, and you cannot have the same password as you had previously. It remembers something like 20 of your last passwords. I discovered most people simply increment a digit at the end of their password, so "thisismypassword1" becomes "thisismypassword2" then 3, 4, 5 etc. Since all of these passwords are stored somewhere, I wondered if there was any weakness in the hashes themselves, for standard hashing algorithms used to store passwords like MD5. Could a hacker increase their chances of brute-forcing the password if they have a list of hashes of similar passwords?

  • ASP.NET MVC Filters: How to set Viewdata for Dropdown based on action paramter

    - by CRice
    Hi, Im loading an entity 'Member' from its id in route data. [ListItemsForMembershipType(true)] public ActionResult Edit(Member someMember) {...} The attribute on the action loads the membership type list items for a dropdown box and sticks it in viewdata. This is fine for add forms, and search forms (it gets all active items) but I need the attribute to execute BASED ON THE VALUE someMember.MembershipTypeId, because its current value must always be present when loading the item (i.e. all active items, plus the one from the loaded record). So the question is, what is the standard pattern for this? How can my attribute accept the value or should I be loading the viewdata for the drop down in a controller supertype or during model binding or something else? It is in an attribute now because the code to set the viewdata would otherwise be duplicated in each usage in each action.

  • Are there any lint tools for C and C++ that check formatting?

    - by Nathan Fellman
    I have a codebase that is touched by many people. While most people make an effort to keep the code nicely formatted (e.g. consistent indentation and use of braces), some don't, and even those that do can't always do it because we all use different editors, so settings like spaces vs. tabs are different. Is there any standard lint tool that checks that code is properly formatted, but doesn't actually change it (like indent but that returns only errors and warnings)? While this question could be answered generally, my focus is on C and C++, because that's what this project is written in.

  • Is It Worth Using Bitwise Operators In Methods?

    - by user1626141
    I am very new to Java (and programming in general, my previous experience is with ActionScript 2.0 and some simple JavaScript), and I am working my way slowly and methodically through Java: A Beginner's Guide by Herbert Schildt. It is an incredible book. For one thing, I finally understand more-or-less what bitwise operators (which I first encountered in ActionScript 2.0) do, and that they are more efficient than other methods for certain sums. My question is, is it more efficient to use a method that uses, say, a shift right, to perform all your divisions/2 (or divisions/even) for you in a large program with many calculations (in this case, a sprawling RPG), or is it more efficient to simply use standard mathematical operations because the compiler will optimise it all for you? Or, am I asking the wrong question entirely?

  • Solution for distributing MANY simple network tasks?

    - by EmpireJones
    I would like to create some sort of a distributed setup for running a ton of small/simple REST web queries in a production environment. For each 5-10 related queries which are executed from a node, I will generate a very small amount of derived data, which will need to be stored in a standard relational database (such as PostgreSQL). What platforms are built for this type of problem set? The nature, data sizes, and quantities seem to contradict the mindset of Hadoop. There are also more grid based architectures such as Condor and Sun Grid Engine, which I have seen mentioned. I'm not sure if these platforms have any recovery from errors though (checking if a job succeeds). What I would really like is a FIFO type queue that I could add jobs to, with the end result of my database getting updated. Any suggestions on the best tool for the job?

  • PHP Magento Screen Scraping

    - by Grant unwin
    I am trying to scrape a suppliers magento site in an effort to save some time because of there being around 2000 products I need to gather info for. I'm totally OK with writing a screen scraper for pretty much anything but i've encountered a major problem. Im using get_file_contentsto gather the html of the product page. The problem is: You need to be logged in, to view the product page. Its a standard magento login, so how can I get round this in my screen scraper? I don't require a full script, just advice on a method. Thanks

  • Force close Android application Phone.apk in landscape mode

    - by user1277086
    Standard Android application Phone.apk with an outgoing call on the tenth of a second can use the landscape screen mode, but if you make a modification of graphic resources, in landscape mode the phone is closed with an error, Eclipse shows it - E / AndroidRuntime (2888): java.lang.RuntimeException: Unable to start activity ComponentInfo {com.android.phone / com.android.phone.InCallScreen}: java.lang.ClassCastException: android.view.AbsSavedState $ 1. I tried to set the AndroidManifest.xml setting [android: screenOrientation = "portrait"] of the article "Force an android activity to always use landscape mode" - the application falls. What can I try to do more? I tried to add a variable to a string android:screenOrientation="portrait" in decompiled Phone.apk on the and

  • Can JAXB store the class name in the XML so that the the deserialize code doesn't need knowledge of the class?

    - by Andrew
    It seems the standard approach for deserializing JAXB XML is to specify the package name when creating the context. Then, JAXB looks up the class based on the root element: JAXBContext jc = JAXBContext.newInstance("com.foo"); Unmarshaller u = jc.createUnmarshaller(); Object o = u.unmarshal(new StringReader("...")); I'm looking for a more flexible approach where I don't have to specify the package name and could still deserialize any object. This would be as simple as JAXB storing the package in the XML, but I can't seem to find out how to do this. I can write the code to do it myself but that would be unpleasant. It would like JAXB to do it, if possible. BTW, I am not using schemas, just Annotations and marshal/unmarshal. Any ideas?

  • How to handle null {id} on route?

    - by MattSlay
    What if a user hits my site with http://www.mysite.com/Quote/Edit rather than http://www.mysite.com/Quote/Edit/1000 In other words, they do not specify a value for {id}. If they do not, I want to display a nice "Not Found" page, since they did not give an ID. I currentl handle this by accepting a nullable int as the parameter in the Controller Action and it works fine. However, I'm curious if there a more standard MVC framework way of handling this, rather than the code I presently use (see below). Is a smoother way to handle this, or is this pretty mush the right way to do it? [HttpGet] public ActionResult Edit(int? id) { if (id == null) return View("QuoteNotFound"); int quoteId = (int)id; var viewModel = new QuoteViewModel(this.UserId); viewModel.LoadQuote(quoteId); if (viewModel.QuoteNo > 0) { return View("Create", viewModel.Quote.Entity); } else return View("QuoteNotFound"); }

  • designing multi module J2EE application

    - by user728947
    Might be my question is abstract or out of context, but i am asking here since i have little idea how this happens. I am wondering how big application/ platform break down there application in to multiple module and how they able to manage modules dependencies. For example in some E-commerce application they tend to break down it in various modules like pricing,promotions,shipping.import/export and many more. when we develop those application we hardly think about the underlying modules and how they have been designed to provides functionalists. Most of those module are not web-applications but are standalone module and not deployed in the web-app as jar files. can any one help me to understand how they break up things or is there any standard way to do this.any help/resources to get insight will really be helpful

  • Context menu for loaded SWF

    - by Palantar
    I have a Flex app with a viewport that loads a series of other swfs. I would like to place a context menu over top of the SWFs when the user right-clicks. To that end, I have set up a fairly standard context menu where each item has a ContextMenuEvent.MENU_ITEM_SELECT event handler. One problem: The eventHandler never gets called. If I place the context-menu code anywhere else in the app, i.e. not on top of a loaded SWF, everything works fine. However, when I place the exact same code on the SWF viewport, the context menu items appear, but the eventHandlers are never called. Any ideas?

  • Programming practice

    - by exc1z
    I've decided to get some experience working on some project this summer. Due to local demand on market I would prefer to learn Java (Standard and Enterprise Editions). But I can't even to conjecture what kind of project to do. Recently I had some ideas about C. With C I could to contribute to huge Linux projects. I don't mean that my work will be surely commited. I could get the code and practice with it. But C it's not right thing to get good job in my area. In case of JavaSE there is a chance to develop some desktop applications. But thinking about JavaEE I get stuck. I'll be very thankful for answers.

  • What is the ISO C++ way to directly define a conversion function to reference to array?

    - by ben
    According to the standard, a conversion function has a function-id operator conversion-type-id, which would look like, say, operator char(&)[4] I believe. But I cannot figure out where to put the function parameter list. gcc does not accept either of operator char(&())[4] or operator char(&)[4]() or anything I can think of. Now, gcc seems to accept (&operator char ())[4] but clang does not, and I am inclined to not either, since it does not seem to fit the grammar as I understand it. I do not want to use a typedef because I want to avoid polluting the namespace with it.

  • Any way to surround code block with Curly Braces {} in VS2008?

    - by Jim McKeeth
    I always find myself needing to enclose a block of code in curly braces { }, but unfortunately that isn't included in the C# surround code snippets, which seems to be an oversight. I couldn't find anything on building your own surround snippets either (just other kinds of snippets). I am actually running Resharper too, but it doesn't seem to have this functionality either (or I haven't figured how to activate it). We have a coding standard of including even a single line of code after an if or else in curly braces, so if I could just make Resharper do that refactor automatically that would be even better!

  • Cascading Dropdown Listboxes with Selenium

    - by Jon
    I am having great difficultly testing cascading dropdown boxes with Selenium. I would like to know what the standard approach is for this. I'm a bit unclear as to which commands to use i.e. ClickAndWait, WaitForTextPresent etc. It seems a little bit of a hack to try and get this to work. Has anyone got selenium to correctly test this out? An example scenario would be to have 3 listboxes which have Car Make, Model and Colour. Each one is populated in turn by the other. Selenium needs to somehow wait for the next listbox to populate before preceeding with the test.

  • An easy way to replace fread()'s with reading from a byte array?

    - by Sam Washburn
    I have a piece of code that needs to be run from a restricted environment that doesn't allow stdio (Flash's Alchemy compiler). The code uses standard fopen/fread functions and I need to convert it to read from a char* array. Any ideas on how to best approach this? Does a wrapper exist or some library that would help? Thanks! EDIT: I should also mention that it's reading in structs. Like this: fread(&myStruct, 1, sizeof(myStruct), f);

  • What's the state of support for SHA-2 in various platforms?

    - by Cheeso
    I read that SHA-1 is being retired from the FIPS 180-2 standard. Apparently there are weaknesses in SHA-1 that led to this decision. Can anyone elaborate on the basis for that decision? Are there implications for the use of SHA-1 in commercial applications? My real questions are: What is the state of SHA-2 support in various class libraries and platforms? Should I attempt to move to SHA-2? Interested in mainstream platforms: .NET, Java, C/C++, Python, Javascript, etc.

  • PHP/Codeigniter processing a list with javascript

    - by user270797
    I have a list of items that the user can select. I want it to be more user friendly than standard checkboxes so I have seperate div's each with a unique id. When user clicks an item, I use javascript to display a tick on top of that item and change the style to show that it is highlighted. Im trying to work out how I can pass the list of id's when the form is submitted. Remember, if the user unticks an item, it should be removed from the list, I was thinking of using comma seperated values in a hidden text field but couldnt work out how to remove items from the start of the list if they were deselected

  • How to track IIS server performance

    - by Chris Brandsma
    I have a reoccurring issue where a customer calls up and complains that the web site is too slow. Specifically, if they are inactive for a short period of time, then go back to the site, there will be a minute-two minute delay before the user sees a response. (the standard browser is Firefox in this case) I have Perfmon up and running, the cpu utilization is usually below 20% (single proc...don't ask). The database is humming along. And I'm pulling my hair out. So, what metrics/tools do you find useful when evaluating IIS performance?

  • Why is the 'this' keyword not a reference type in C++ [closed]

    - by Dave Tapley
    Possible Duplicates: Why ‘this’ is a pointer and not a reference? SAFE Pointer to a pointer (well reference to a reference) in C# The this keyword in C++ gets a pointer to the object I currently am. My question is why is the type of this a pointer type and not a reference type. Are there any conditions under which the this keyword would be NULL? My immediate thought would be in a static function, but Visual C++ at least is smart enough to spot this and report static member functions do not have 'this' pointers. Is this in the standard?

  • Backbone inheritance - deep copying

    - by Ed .
    I've seen this question regarding inheritance in Backbone: Backbone.js view inheritance. Useful but doesn't answer my question. The problem I'm experiencing is this: Say I have a class Panel (model in this example); var Panel = Backbone.Model.extend({ defaults : { name : 'my-panel' } }); And then an AdvancedPanel; var AdvancedPanel = Panel.extend({ defaults : { label : 'Click to edit' } }); The following doesn't work: var advancedPanel = new AdvancedPanel(); alert(advancedPanel.get('name')); // Undefined :( JSFiddle here: http://jsfiddle.net/hWmnb/ I guess I can see that I can achieve this myself through some custom extend function that creates a deep copy of the prototype, but this seems like a common thing that people might want from Backbone inheritance, is there a standard way of doing it?

  • html5media & flowplayer wmode issues...

    - by minusidea
    I'm working on our new homepage and need to implement a solution that will run a video across iphone/ipad and the standard web browsers. I found a pretty decent solution with html5media - http://code.google.com/p/html5media/ but ran across an issue with a jquery dropdown falling behind the the swf object (this only happens on FF & IE - works fine on Safari & Chrome because it's loading mp4 instead of a swf object). I know the issue is the wmode setting but can not for the life of me figure out where to set it in the html5media (http://html5media.googlecode.com/svn/trunk/src/html5media.min.js). I'm hoping someone can help me or possibly give me a better solution of implementing the video. You can see the development page at idssite(dot)com/development/index.php - Sorry I can't link I'm being stopped by the spam prevention mechanism. Thanks

The import of standard product is successful but not for the product with customs options. For customs option, missing "info_buyRequest" valu in database. The technical support of magento we responded "the import process currently can't handle importing products with custom options". Magento use custom options when ordering a product with customs options on website. What features do magento use to fill in the fields "info_buyRequest" and "Product_options" when ordering? Have you see a extension pack for import file order with product contains customs options? Thanks for your help.
