  • MVVM application architecture, where to put dependency injection configuration class, BusinessLayer and Common interfaces?

    - by gt.guybrush
    Planning my architecture for an MVVM application I come to this: MyApp.UI View MyApp.BusinessLayer ViewModel MyApp.DataAccessLayer RepositoryImplEF MyApp.DomainLayer DomainObject RepositoryInterface MyApp.Common Logging Security Utility (contains some reflection method used by many levels) CustomException MyApp.UnitTest I was inspired by Domain-driven-desing, test-driven-development and onion architecture but not sure to have done all well. I am not sure of a couple of things: where to put dependency injection configuration class? In the common project? where to put BusinessLayer interfaces? in Domain layer? where to put Common interfaces? in Domain layer? But Common in referenced from domain (for some reflection utilities and for DI if the response to 1. is yes) and circular reference isn't good

  • Should I add rel nofollow to internal links which already have meta noindex?

    - by CamSpy
    Let's say I have a products page with listing producsts and the page has pagination. I would like the 1st page to have all the SE ranking weight so I decided to put meta noindex on the rest of the paginated pages (from page 2 to N). My common sense says that if I don't want pages to not get indexed, I shouldn't also pass link/PR juice to these pages. (Is that smart?) What happens if I set rel="nofollow" for all pagination links from page 2 to page N?

  • (Joomla 1.6) Template position descriptions don't refresh

    - by avanwieringen
    I want to change a description of a template position, so when I go to Admin-Extensions-Module Manager I see a different description of a module position in the position list when I edit a module. However, when I change (for instance) the template 'beez_20' and want to rename the name of the position 'debug', I change the description (TPL_BEEZ_20_POSITION_DEBUG) in the language file 'languages\en-GB\en-GB.tpl_beez_20.sys.ini' to something different, say 'Abracadabra'. However, the changes don't appear in the position list and I can find no reference whatsoever of how or when the ini files are read or maybe cached. Does anyone has a clue?

    For debugging purposes me and my collegue wanted to dump details of the arbitrary object, and created function that uses LINQPad Dump functionality (thanks to http://stackoverflow.com/a/6035014/52277 and original http://linqpad.uservoice.com/forums/18302-linqpad-feature-suggestions/suggestions/447166-make-dump-extension-method-available-in-visual-s discussion)    public static string DumpToHtmlString<T>(this T objectToSerialize)        {            string strHTML = "";            try            {                var writer = LINQPad.Util.CreateXhtmlWriter(true);                writer.Write(objectToSerialize);                strHTML = writer.ToString();            }            catch (Exception exc)            {                Debug.Assert(false, "Investigate why ?" + exc);            }            return strHTML;        }You will need to add the linqpad executable as a reference in your project.TO DO similar in plain text ,look at https://github.com/ServiceStack/ServiceStack.Text StringExtensions , e.g. JsonSerializer/CsvSerializer or http://objectdumper.codeplex.com/

  • Subscribe/Publish Model in Web-based Application (c#) - Best Practices for Event Handlers

    - by KingOfHypocrites
    I was recently exposed to a desktop application that uses an publish/subscribe model to handle commands, events, etc. I can't seem to find any good examples of using this in a web application, so I wonder if I am off base in trying to use this for web based development (on the server side)? I'm using asp.net c#. My main question in regards to the design is: When using a publish/subscribe model, is it better to have generic commands/events that pass no parameters and then have the subscribers look at static context objects that contain the data relevant to the event? Or is it better to create custom arguments for every event that contain data related to the event? The whole concept of a global container seems so convenient but at the same time seems to break encapsulation. Any thoughts or best practices from anyone who has implemented this type of model in a web based application? Even suggestions on this model out of the scope of my question are appreciated.

  • DNSCrypt-Proxy specific usage

    - by trekkiejonny
    I have some specific usage questions about DNSCrypt-Proxy. I followed a guide and ended with the command dnscrypt-proxy --daemonize –user=dnscrypt Without any further switches does it default to using OpenDNS's resolver server? I want to use specific servers, I found reference to pointing it to the full path of a CSV file. What is the CSV format for use with DNSCrypt? Would it be "address:port,public key"? Does it go in order of working addresses? For example, first resolver doesn't connect it moves on to the second line of the CSV, then third etc. Lastly, would this question be more appropriate in another StackExchange section?

  • How do I swap two objects in a GC language without triggering GC?

    - by TenFour04
    I have two array lists. that I want to swap each frame. My question is, does the variable 'temp' need to be a member variable to avoid triggering GC, assuming this method is called on dozens of objects each frame? I'm not creating a new object, just a new reference to an object. public void LateUpdate(){ ArrayList<int> temp = previousFrameCollisions; previousFrameCollisions = currentFrameCollisions; currentFrameCollisions = temp; currentFrameCollisions.clear(); } I've been told there's no reason to make a primitive into a member variable just to avoid GC, so my best guess is that this also applies to object references.

  • OpenGLES 2.0 gluunProject

    - by secheung
    I've spent more time than i should trying to get my ray picking program working. I'm pretty convinced my math is solid with respect to line plane intersection, but I believe the problem lies with the changing of the mouse screen touch into 3D world space. Heres my code public void passTouchEvents(MotionEvent e){ int[] viewport = {0,0,viewportWidth,viewportHeight}; float x = e.getX(), y = viewportHeight - e.getY(); float[] pos1 = new float[4]; float[] pos2 = new float[4]; GLU.gluUnProject( x, y, 0.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos1, 0); GLU.gluUnProject( x, y, 1.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos2, 0); } Just as a reference I've tried transforming the coordinates 0,0,0 and got an offset. It would be appreciated if you would answer using opengl es 2.0 code. Thanks

  • Restricted Flow Of Power

    - by user13827
    I'm sure all is fine, but i need some reassurance. Last month my company launched consolidated two of their websites into one new website. www.fdmgroup.com and www.fdmacademy.com into a newly designed www.fdmgroup.com. Because the FDM Academy grew as it's own brand we decided not to just forward the domain to the fdmgroup website, but instead just mirror the new FDM Group website and use a canonical tags to the FDM Group domain (so the link juice will pass to the FDM Group domain pages) The website has be live for nearly a month and i don't believe any power has passed down through the FDM Group website to it's deeper pages even though 301 redirects from the legacy group and academy domains in place. I am also seeing the same problem on the FDM Academy domain, but i expect to see this as every page has a canonical to the same page on the Is there anything which is restricting the flow of power through the site, or am i just being impatient. Thanks in advance Jon

  • What is the minimum of shader I need to use to run basic calculation on GPU?

    - by Jinxi
    I read, that the Hull Shader, Domain Shader, Geometry Shader and Pixel Shader can be used optional. So, is the Vertex Shader optional too? If no: What does a basic Vertex Shader look like? Just like a simple pass through? Is the Vertex Shader necessary to tell what kind of datastructure (Van Stripes or Meshes) are used? What can I do, with just the vertex shader? Are the fixed functions working without any help of programming a programmable stage?

  • Is there benifit to maintain a large project with bad code?

    - by upton
    I'm currently maintain a large project with more than 100000 LOC. The code use the MFC as its framework, in genral, it only has interface part which heavily use the mfc api and a business logic part which full of bad code, confusing logic. The company has some small features delivered to the customer each year(most features are adding code to exisiting project, finding some reference of some api or variable and it' s no different with fixing 3-4 bugs ), most of the tasks are to resove issue and optimize performance . Like other company with maintaining position, it value people who knows much logic about its product. There are people who can quickly finish the job on such project, is it worth to train myself like such a programmer? Is there benifits to work on such project for a long time?

  • how to avoid workaholic tag

    - by Shirish11
    As we all know a programmer just needs a computer and a network connection. When these things are available at your disposal you can program anywhere in the world. Now this is causing me a bit of problems. Since its not necessary to work at your workplace only you are asked anytime of your vacation or week-off to help out the client on reported bug. Also if you do enjoy doing it at your pass time, any one seeing you stare at the computer may treat you workaholic which I don't enjoy. How do you make them realize that its not just about the work.It can be a hobby also. In my understanding a workaholic is a person who works to earn but an enthusiast is the one who works to learn.

  • Best practice, or generally best way to set up web-hosting server, permissions, etc. [closed]

    - by Jagot
    Hi, I'm about to set up a server upon which a friend and I will be hosting web sites, and I'll be using Debian. I've set up a LAMP solution many times just to using for local testing purposes, but never for actual production use. I was wondering what are the best practices are in terms of setting the server up, in reference specifically to accessing the web root directory. A couple of the options I have seen: Set up a single user account on the server for us both to use and use a virtual host to point to the somewhere in the home directory, e.g. /home/webdev/www. Set each of us up a user account, and grant permissions in some way to /var/www (What would be the best way? Set up a new group?) I want to get this right when I first set this up as there won't be any going back for a while once our first site is up and running. Appreciate any guidance in advance.

  • How can I reconnect to a ssh session after a broken pipe?

    - by Chauncellor
    So I was running apt-get upgrade on a server when the router decided it had been too long since it last made me angry: It dropped all connection. Moral of the story is to use screen a lot when you're on a bum router. Anyway, I logged back in and found in htop that the process was still hanging there, still waiting for my Y/n to upgrade (hadn't hit it yet, luckily). Is there any way I can reattach to a session that had been broken off? I ended up just killing it since it wasn't in the middle of package management but it would be great to know for future reference.

Application should have : * database support ( create two or three table ) * GUI ( what I have created should be seen ) Example : Assume that I have created a table ; X_table : | A | B | C | D | After creating table, I am loading data | A | B | C | D | | 1 | 11 | b | f | - | 3 | 12 | a | o | - data | 4 | 13 | r | o | - When I am opening application not for loading data, I want see data in graphical interface. Are there any open source application which have above feature ? Application can be so simple, * no internet connection * support only one database * static table creation ( once created never changed ) Application can be run Ubuntu 12.04 and/or Windows. In other words, I am wanting database viewer and editor. EDIT: I should load pdf file, image etc. or give path of the file to the application. This link can be reference to my question .

  • Alternatives to OAuth?

    - by sdolgy
    The Web industry is shifting / has shifted towards using OAuth when extending API services to external consumers & developers. There is some elegance in simple....and well, the 3-step OAuth process isn't too bad ... i just find it is the best of a bad bunch of options. Are there alternatives out there that could be better, and more secure? The security reference is derived from the following URLs: http://www.infoq.com/news/2010/09/oauth2-bad-for-web http://hueniverse.com/2010/09/oauth-2-0-without-signatures-is-bad-for-the-web/

  • Pattern for loading and handling resources

    - by Enoon
    Many times there is the need to load external resources into the program, may they be graphics, audio samples or text strings. Is there a patten for handling the loading and the handling of such resources? For example: should I have a class that loads all the data and then call it everytime I need the data? As in: GraphicsHandler.instance().loadAllData() ...//and then later: draw(x,y, GraphicsHandler.instance().getData(WATER_IMAGE)) //or maybe draw(x,y, GraphicsHandler.instance().WATER_IMAGE) Or should I assign each resource to the class where it belongs? As in (for example, in a game): Graphics g = GraphicsLoader.load(CHAR01); Character c = new Character(..., g); ... c.draw(); Generally speaking which of these two is the more robust solution? GraphicsHandler.instance().getData(WATER_IMAGE) //or GraphicsHandler.instance().WATER_IMAGE //a constant reference

  • Does your team develop their supporting tools or this should be outsourced out of it?

    - by Pierre 303
    By supporting tools, I mean: reference data manager, like virus definition for anti-virus software test data generator level builders for games simulators or advanced mocking systems Does the team building the core product (in the case above, the game or the anti-virus) should be part of the development of the supporting tools significantly, or this is a task you would outsourced out of the team to help it focus on the product? I don't have enough experience to evaluate the pros & cons of each, so I'm hopping you would come up with personal experiences to share, or even studies or papers you read on the subject.

  • VB6 general search form

    - by SilentRage47
    I'm working on an old vb6/access2003 app which is used to handle orders, bills of materials and that sort of things. I'm thinking about creating a form that I call every time the users needs to search for something. This should work like these: Click on the field to complete, let's say name of a buyer Open new form, search for the client and click on it Return the name of the buyer to the previous form (probably the header of the order) So, I would need to pass to the new form something that identify the type of search I have to do (so what access table to open) and return some values. Is my idea correct or there something better? I would like to use only one form for all the searches, now the app works with a lot of msflexgrid for every form.

  • Creating a WARP device in managed DirectX

    - by arex
    I have a very old graphic card that only supports shader model 2, but I need shader model 3 or up for the app I am developing. I tried to use a reference device but it seems to run very slowly, then I found some samples in C++ that allows me to change to a WARP device and the performance is good. I am using C# and I don't know how to create such type of device. So the question is: how do I create a WARP device in C#? Thanks in advance.

  • Installing ImageMagick for C(++) on Ubuntu 12.10

    - by user167747
    I'm having a hard time installing the ImageMagick software for Ubuntu 12.10. So, I want the C and C++ API, not much more. Now when I go to imagemagick.org, they have a binary package for unix, namely an rpm. When I download and launch it, RPM complains that firstly I should be using alien, and secondly there are like 10000 missing dependencies. If I use alien to create a deb file, and the install it via the software center, the package does indeed install, but only the command line interface - no includes, anything. Same with apt-get imagemagick. (BTW - wtf, they don't have support for ubuntu?) I tried compiling from source (which I shoudn't be doing anyway - I'm not expecting much customization am I?), and then the includes are present, but the programs won't compile complaining about "undefined reference" and then a list of everything that isn't pure C (and I'm using the command imagemagick.org told me to use, namely cc -o wand pkg-config --cflags --libs MagickWand wand.c) so clearly I'm doing something wrong. Any help would be much appreciated.
