  • How can I access the scanner functionality of my Samsung CLX 3175N over the network?

    - by Roger De Backer
    I have a Samsung CLX 3175N network capable color laser printer/scanner which was sold as being Linux compatible. Whereas the printer undeed works in the network. It has been impossible up to now to get the scanner working under Ubuntu (safe for using Windows XP running in Virtualbox on the Ubuntu client), but that is not my understanding of Linux compatibility. Is there anybody who knows a method to access a network Scanner in Ubuntu?

  • Is it better to load up a class with methods or extend member functionality in a local subclass?

    - by Calvin Fisher
    Which is better? Class #1: public class SearchClass { public SearchClass (string ProgramName) { /* Searches LocalFile objects, handles exceptions, and puts results into m_Results. */ } DateTime TimeExecuted; bool OperationSuccessful; protected List<LocalFile> m_Results; public ReadOnlyCollection<LocalFile> Results { get { return new ReadOnlyCollection<LocalFile>(m_Results); } } #region Results Filters public DateTime OldestFileModified { get { /* Does what it says. */ } } public ReadOnlyCollection<LocalFile> ResultsWithoutProcessFiles() { return new ReadOnlyCollection<LocalFile> ((from x in m_Results where x.FileTypeID != FileTypeIDs.ProcessFile select x).ToList()); } #endregion } Or class #2: public class SearchClass { public SearchClass (string ProgramName) { /* Searches LocalFile objects, handles exceptions, and puts results into m_Results. */ } DateTime TimeExecuted; bool OperationSuccessful; protected List<LocalFile> m_Results; public ReadOnlyCollection<LocalFile> Results { get { return new ReadOnlyCollection<LocalFile>(m_Results); } } public class SearchResults : ReadOnlyCollection<LocalFile> { public SearchResults(IList<LocalFile> iList) : base(iList) { } #region Results Filters public DateTime OldestFileModified { get { /* Does what it says. */ } } public ReadOnlyCollection<LocalFile> ResultsWithoutProcessFiles() { return new ReadOnlyCollection<LocalFile> ((from x in this where x.FileTypeID != FileTypeIDs.ProcessFile select x).ToList()); } #endregion } } ...with the implication that OperationSuccessful is accompanied by a number of more interesting properties on how the operation went, and OldestFileModified and ResultsWithoutProcessFiles() also have several more siblings in the Results Filters section.

  • How does a search functionality fit in DDD with CQRS?

    - by Songo
    In Vaughn Vernon's book Implementing domain driven design and the accompanying sample application I found that he implemented a CQRS approach to the iddd_collaboration bounded context. He presents the following classes in the application service layer: CalendarApplicationService.java CalendarEntryApplicationService.java CalendarEntryQueryService.java CalendarQueryService.java I'm interested to know if an application will have a search page that feature numerous drop downs and check boxes with a smart text box to match different search patterns; How will you structure all that search logic? In a command service or a query service? Taking a look at the CalendarQueryService.java I can see that it has 2 methods for a huge query, but no logic at all to mix and match any search filters for example. I've heard that the application layer shouldn't have any business logic, so where will I construct my dynamic query? or maybe just clutter everything in the Query service?

  • What is the most effective way to add functionality to unfamiliar, structurally unsound code?

    - by Coder
    This is probably something everyone has to face during the development sooner or later. You have an existing code written by someone else, and you have to extend it to work under new requirements. Sometimes it's simple, but sometimes the modules have medium to high coupling and medium to low cohesion, so the moment you start touching anything, everything breaks. And you don't feel that it's fixed correctly when you get the new and old scenarios working again. One approach would be to write tests, but in reality, in all cases I've seen, that was pretty much impossible (reliance on GUI, missing specifications, threading, complex dependencies and hierarchies, deadlines, etc). So everything sort of falls back to good ol' cowboy coding approach. But I refuse to believe there is no other systematic way that would make everything easier. Does anyone know a better approach, or the name of the methodology that should be used in such cases?

  • Site/Project to convert in Java web pages as it is now with complete functionality, look and feel.

    - by pirzada
    I have completed a web site Surfrainbow using ASP.NET and working fine. Completely dynamic with back-end management and Ajax support. This site has to be 100% same as in Java considering look and feel. Conversion is for learning purpose. I am new to Java and learning it fast. I don't want to know how to learn Java. Just want to know what is needed for this project to work in Java related technologies. Want to know How would you handle this project. My questions are 1 - What technologies I will be needing to make this project like Servlets, JSP, JSF etc? 2 - What is needed for Ajax support. Is JQuery supported :)? 3 - What should be used for MVC? 4 - ASP.NET has master pages to simplify design. Anything like this in Java? 5 - Which IDE is best for Java development. JDeveloper/NetBeans? Anything else you can share. Thanks

  • Is it possible to set a VPN through Tor? and have functionality for Software Updates?

  • How would you TDD the functionality of getting the corresponding process of a running windows service?

    - by Matt Spinelli
    Purpose Over the last year or more I've been learning unit testing via books I've read recently like The Art of Unit Testing, Working Effectively with Legacy Code, and others. I've also been using unit tests, mocking frameworks, and the like, periodically at work and definitely see the value. However, I'm still having a hard time wrapping my mind around TDD (as opposed to TAD) when the situation calls for code that is gong to mostly use external API calls. Problem to solve Get the process associated with a windows service using the service name. example: Function GetProcess(ByVal serviceName As String) As Process Rules Show each major iteration in production & test code using TDD No need to see any other code or configuration that is required to get things to run. Just curious about the interfaces, concrete classes, and test methods. C# or VB.NET Must use the .Net framework regarding services/processes (i.e. System.Diagnostics.Process) Test Frameworks: Nunit or MSTest Isolation Frameworks: Moq, Rhino Mock, or Microsoft Moles Must write true unit tests (no integration tests) Additional notes As far as I can tell there are two approaches design wise. Use an Inversion of Control approach along with using the Adapter and/or Facade patterns to wrap the underlying .net framework objects dealing with processes and services. Keep the .net framework code in the class containing the Get Process method and use code detouring (interception) via Microsoft Moles to isolate the hard dependencies from the method under test.

  • What actions should I not rely on the packaged functionality of my language for?

    - by David Peterman
    While talking with one of my coworkers, he was talking about the issues the language we used had with encryption/decryption and said that a developer should always salt their own hashes. Another example I can think of is the mysql_real_escape_string in PHP that programmers use to sanitize input data. I've heard many times that a developer should sanitize the data themselves. My question is what things should a developer always do on their own, for whatever reason, and not rely on the standard libraries packaged with a language for it?

  • How can I get started using TDD to code some simple functionality?

    - by Gabriel
    I basically have the gist of TDD. I'm sold that it's useful and I've got a reasonable command of the MSTEST framework. However, to date I have not been able to graduate to using it as a primary development method. Mostly, I use it as a surrogate for writing console apps as test drivers (my traditional approach). The most useful thing about it for me is the way it absorbs the role of regression testing. I have not yet built anything yet that specifically isolates various testable behaviors, which is another big part of the picture I know. So this question is to ask for pointers on what the first test(s) I might write for the following development task: I want to produce code that encapsulates task execution in the fashion of producer/consumer. I stopped and decided to write this question after I wrote this code (wondering if I could actually use TDD for real this time) Code: interface ITask { Guid TaskId { get; } bool IsComplete { get; } bool IsFailed { get; } bool IsRunning { get; } } interface ITaskContainer { Guid AddTask(ICommand action); } interface ICommand { string CommandName { get; } Dictionary<string, object> Parameters { get; } void Execute(); }

  • What to use for "localhost" that includes PHP/SQL functionality?

    - by Jack
    I really do not want to install Linux at the moment, I would have to borrow a USB key, move files, format it, flash it, format it again, move files back, give it back... What would you recommend that is lightweight, easily and cleanly uninstallable afterwards (will install Linux when I get a new DVD-ROM, which will be in ~2 weeks), that also supports PHP and SQL? To be precise, I want to install a Wordpress blog, a few plugins, etc, and develop a theme. If there is no such thing for Windows (7, x64 if that matters), let me know too, I will borrow the USB key then (even though it's a pain).

  • Should I extract specific functionality into a function and why?

    - by john smith optional
    I have a large method which does 3 tasks, each of them can be extracted into a separate function. If I'll make an additional functions for each of that tasks, will it make my code better or worse and why? Edit: Obviously, it'll make less lines of code in the main function, but there'll be additional function declarations, so my class will have additional methods, which I believe isn't good, because it'll make the class more complex. Edit2: Should I do that before I wrote all the code or should I leave it until everything is done and then extract functions?

  • How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

    - by Mmmm
    I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

  • Integrating feature request functionality directly into the business software you write?

    - by Aaron Anodide
    What are relative merits of something like a button on a piece of custom bizware that says, "press me to ask for a feature" or "click here if something didn't work right". The problem I'm trying to remedy is the general lack of formality surrounding feature requests. Most specifically, the rate at which I receive walk-ups from end-users. Taken one at a time, it can be beneficial, but sometimes it can hinder productivity on the larger scale. Has anyone done something like this and has it been a general success or alternately somewhat a waste of time. My instincts are not giving me a hint here.

  • How to add SMS text messaging functionality to my website?

    - by jessegavin
    I want to add the ability to send reminders to people via email and SMS for specific events that they have signed up for on a web application that I am building. The email part is not difficult, but I am wondering where to find a good solution for sending SMS messages. It would also be a plus if this solution allowed two-way SMS communication with my web application so that people would be able to reply with a CONFIRM or CANCEL type of a message. Has anyone implemented something like this? Does anyone know of good tools out there? EDIT: I am realizing that this is more of a "lots of ways to skin this cat" type of question and so I changed it to community wiki.

  • What parts of functionality should be refactored into a directive?

    - by Sprottenwels
    I am creating an application from legacy code using AngularJS. I wonder what parts of my code should be moved into a directive. For example, iI had thought of moving a table which is used multiple times across the application into a directive. The tables alter from headings and size. Is it worth the effort or even a good practice to turn such things into their own directives or should I create each table in a unique way?

  • Is it okay to just add a page or two PHP page to add some functionality to a Drupal site?

    - by Zaemz
    I'm not familiar with Drupal, really. I can dig around the admin interface and navigate the directories and find the files that I need to just fine as well. What I'm really not familiar with is adding modules or extending modules. The site currently takes an order and sets up recurring payments through Ubercart and uses Authorize.net as a gateway. Right now, when a payment fails, a single e-mail gets sent out to the admin. We'd like to extend it to send an e-mail to the user and let them change their payment information through another page on the site. Authorize has a service called Silent Post URL that basically just posts a carbon copy in XML to whatever URL you give it. We'd like to accept that XML, deserialize it, parse the data, send a notice to the user and give them the page for updating their information. So, I guess it'll be two PHP pages. One for the XML API call from Authorize.net, and then one for the page for the users' to update their payment information. Could I just create two simple pages each handling their own tasks, or should I check out properly extending a module? If it's appropriate for me to write up the pages and not have to hook them into the module, what would be the best way to handle setting up what needs to get done? (The most experience I've had with extending a PHP site has been hacking away at someone else' poorly constructed, custom framework, so if anyone has any good resources perhaps on PHP best practices that they could share through a PM or a comment, I'd appreciate It) (Also, I'm still getting the hang of Stack Exchange, so if this isn't appropriate please let me know. I'll delete it.)

  • How can I duplicate the UI functionality of Google Fastflip?

    - by marcamillion
    Trying to get the same functionality as Google FastFlip. Not just with the thumbnails, but even for the larger images too. Notice how when you click on a story, you see the main story front and center, and you see smaller half-screens of previous and next stories. How can I get that functionality? Is there a plugin for one of the JS frameworks that does this already? I also love the speed and feel of flipping through the images.

  • Is it possible to make notepad++ support tamil language functionality?

    - by Pandiya Chendur
    Notepad++ (from v2.3) supports the multilanguage functionality by means of a translated xml file (from english.xml). Normally you don't need it if you install Notepad++ by its installer. You may need the language file if you install Notepad++ from zip format binary (or if your language is not supported by NSIS installer). Is it possible to make notepad++ support tamil language functionality?

  • What's the benefit of declaring class functions separately from their actual functionality?

    - by vette982
    In C++, what's the benefit of having a class with functions... say class someClass{ public: void someFunc(int arg1); }; then having the function's actual functionality declared after int main int main() { return 0; } void someClass::someFunc(int arg1) { cout<<arg1; } Furthermore, what's the benefit of declaring the class in a .h header file, then putting the functionality in a .cpp file that #includes the .h file?

    Forbes company recently conducted a survey to figure out the world’s Billionaires list and has released it listing the top 20 names of the Billionaires. The company says that for the third time in the last three years the world has a new richest man for this year. So it means that Bill Gates was beaten up by someone else in world. Who is the new richest man in the world?   Forbes.Com announced the richest man in world and this time it is not Bill Gates. But it is Carlos Slim Helu who is into Telecom industry. Carlos lives in Mexico and he had the third richest man’s place last year. Having shown a Net worth of $ 53.5 Billion, Carlos has increased $18.5 Billion in a year. Carlos swooped on the privatization of Mexico’s national telephone service during the last decade and now has achieved the world’s first richest man. Following Carlos, in the second position is Bill Gates with the Nett worth of $53 Billion. As Bill Gates requires no great introduction, lets move on to the next place. The third place is occupied by Warren Buffett followed by Mukesh Ambani and Lakshmi Mittal in fourth and fifth places respectively.

  • Http Hanlder must be reset with each deployment. How can I add this functionality to the web.config

    - by user42942
    My application is a dotnet 4 hybrid - MVC in some areas, web forms in others. This application was recently upgraded to dotnet 4 and includes a lot of older code and some mismatched parts. Unfortunately it includes a telerik component that requires me to run the Application pool in classic mode. In order to fix this (in IIS7) I have to add a handler mapping to the IIS configuration. This mapping is basically a wildcard mapping that points the wildcard path "*" to the %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll. The problem I am running into is this: For some reason this mapping gets dropped when deploying the site. So, can I add the functionality of this mapping to the web config? If so, How? Or is there another solution to make this manually added mapping "sticky" so that it remains in place during and after a deployment? (I am also asking this on StackOverflow, as I'm not sure if this should be a coding question or a Server question)

  • What version of Windows server is needed for RemoteApp functionality?

I tried to figure this out via Microsoft's website, but I couldn't get a clear bead on how exactly what YEARS (2008, 2012, etc.) and/or what EDITIONS (Data Center vs. Standard vs. Foundation vs. Essentials) of Windows Server support RemoteApp stuff.
