• Valid concerns over shared developer team

  - by alphadogg

  Say your company is committed (and don't want to consider not doing this) to sharing/pooling a development team across a handful of business units. What would you setup as concerns/expectations that must be cleared before doing this? For example: Need agreement between units on how much actual time (FTE) is allocated to each unit Need agreement on scheduling of staff need agreement on request procedure if extra time is required by one party etc... Have you been in a situation like this as a manager of one unit destined to use this? If so, what were problems you experienced? What would you have or did implement? Same if you were the manager of the shared team. Please assume, for discussion, that the people concerned know that you can swap devs in and out on a whim. I don't want to know the disadvantages of this approach; I know them. I want to anticipate issues and know how to mitigate the fallout.

• Develop website locally and push updates on Remote Server using Git

  - by John

  Together with a friend we are looking to develop a website (using Symfony2). We are on a Shared Hosting with SSH access. Below is the environment we'd like to setup: * Use git as Version Control (we are new to Git) * Share the tasks and develop on our local machines * Push the updates onto the remote server Here's our initial thoughts on how to do it (assuming Git is already running both locally and remotely): * Install Symfony on the Remote Server (basic setup) * Get a clone (using Git) of the project locally * Develop project locally and push updates (using Git) on the remote server Does this approach make sense, if not, any recommendations? Thanks

• SEO and unique IDs in urls

  - by kokoko

  I have a web site who's home page is at http://domain.com when a new user first hits the web site I'm creating a unique id of 5 chars for them (for example 'abcde' and redirecting them to http://domain.com/abcde so they can later bookmark and return to their workspace. My question is what's the best approach for SEO purposes, I need the main url domain.com to be indexed but google will also get the redirect and will not index the main page. I know about canonical urls, but this applies only when the domain.com url does not redirect also should I use 301 or 302 code in the redirect ?

• What is the need for 'discoverability' in a REST API when the clients are not advanced enough to make use of it anyway?

  - by aditya menon

  The various talks I have watched and tutorials I scanned on REST seem to stress something called 'discoverability'. To my limited understanding, the term seems to mean that a client should be able to go to http://URL - and automatically get a list of things it can do. What I am having trouble understanding - is that 'software clients' are not human beings. They are just programs that do not have the intuitive knowledge to understand what exactly to do with the links provided. Only people can go to a website and make sense of the text and links presented and act on it. So what is the point of discoverability, when the client code that accesses such discoverable URLs cannot actually do anything with it, unless the human developer of the client actually experiments with the resources presented? This looks like the exact same thing as defining the set of available functions in a Documentation manual, just from a different direction and actually involving more work for the developer. Why is this second approach of pre-defining what can be done in a document external to the actual REST resources, considered inferior?

• Automatically analyze excel files

  - by dole doug

  I have to replicate a manual generation of a large number of excel files. I started to manually track the relations between cells ( files, formulas, etc). I also had a talk with the person which generates those files. For now I have a general understanding about how the excel files are generated, but "devil is in the details". I assume that I can write a script which will generate the hierarchy between cells and files, but this might require the same effort as manually noticing the relations. Also, I'm afraid that I'm not too experienced and my app is more prone to error approach than a manual analyze. How to handle this problem? Do you know about an open source project which analyze the excel files in a recursive mode following the formulas ?

• Redirect from https://mydomain.com to http://mydomain.com

  - by Charlie

  Many of my visitors have bookmarked my site already wtih https://mydomain.com. Under the bad advice of a programmer, I put my whole Joomla site under ssl. I do not sell anything or provide any member services. I asked him many times if it would slow my site down - he said it wouldn't. I knew it did, I've researched on this site and realized it does slow the site down because of no cache of the pages. Understood. Please, someone tell me how to get away from it now. I'm not sure how to approach this, should I add something to my htaccess or my main index.php file? I've looked all over the net, there is much advice for adding redirectives for going from http to https, but very few answers regarding the opposite of going from https to http. Thank you very much for your time. I appreciate it.

• How to store character moves (sprite animations)?

  - by Saad

  So I'm thinking about making a small rpg, mainly to test out different design patterns I've been learning about. But the one question that I'm not too sure on how to approach is how to store an array of character moves in the best way possible. So let's say I have arrays of different sprites. This is how I'm thinking about implementing it: array attack = new array (10); array attack2 = new array(5); (loop) //blit some image attack.push(imageInstance); (end loop) Now every time I want the animation I call on attack or attack2; is there a better structure? The problem with this is let's say there are 100 different attacks, and a player can have up to 10 attacks equipped. So how do I tell which attack the user has; should I use a hash map?

• accessing c++ class members with luaplus

  - by cppanda

  i've implemented LuaPlus in my engine eventmanager successfully and really like the flexibility i gained. but i'm still not exactly where i want to by, because i can't link my c++ classes to a lua class. for example i have a Actor class in c++, and i want to be able to create the same class in lua and gain access to members with luaplus, but i can't figure how i can achieve that. Is this actually luaplus built in functionality, or do i have to write my own interface that exchanges data tables between c++ and lua? my current approach would be to fire an event in luascript that creates an new actor class in c++ code, and transfer its id and the data i need to back to lua. when i modify the data i send the modifications back to c++ code again, but i actually thought there's something in luaplus that exposes this functionality already.

• Business Logic Layer in MVC Application

  - by Subin Jacob

  In my ASP MVC application I decided to add another Business Layer and made the model only to have properties. All other functionality like save to db, get from db is done on this new Business layer. So now the controller will be calling this business layer and model for various operations. Is it a good approach to design like this? I decided not to use model for this purpose because I would need a number of models for different actions. (for eg, one for edit and other for create)

• Imitating Exchange Server's "RBAC AuthZ" in my own application... (is there something similar?)

  - by makerofthings7

  Exchange 2010 has a delegation model where groups of winrm cmdlets are essentally grouped into roles, and the roles assigned to a user. (Image source) This is a great & flexible model considering how I can leverage all the benefits of PowerShell, while using the right low level technologies (WCF, SOAP etc), and requiring no additional software on the client side. (Image source) Question(s) Is there a way for me to leverage Exchange's delegation model in my .NET application? Has anyone attempted to imitate this model? If I must start from scratch, how would I go about imitating this approach?

• How do I get my mac to boot from an Ubuntu USB key?

  - by Vinay Gupta

  so if you select "mac" and "usb" on this download page, it gives a series of command line instructions to make a USB key which the MacBook will boot into Ubuntu from. http://www.ubuntu.com/desktop/get-ubuntu/download I've followed them to the letter two or three times on different USB keys, and it doesn't work. There's a very great deal of technical discussion about EFI etc. but this set of instructions seems to suggest it should Just Work, and it doesn't. Help? I'm increasingly unhappy with the more locked-down approach Apple is taking, and I'd quite like to start using Linux with a view to transitioning over to using it as my main operating system, but booting from the CD takes forever, runs slowly and I'm really hoping to get it moving off USB. Can anybody help me?

• Structure gameobjects and call events

  - by waco001

  I'm working on a 2D tile based game in which the player interacts with other game objects (chests, AI, Doors, Houses etc...). The entire map will be stored in a file which I can read. When loading the tilemap, it will find any tile with the ID that represents a gameobject and store it in a hashmap (right data structure I think?). private static HashMap<Integer, Class<GameObject>> gameObjects = new HashMap<Integer, Class<GameObject>>(); How exactly would I go about calling, and checking for events? I figure that I would just call the update, render and input methods of each gameobject using the hashmap. Should I got towards a Minecraft/Bukkit approach (sorry only example I can think of), where the user registers an event, and it gets called whenever that event happens, and where should I go as in resources to learn about that type of programming, (Java, LWJGL). Or should I just loop through the entire hashmap looking for an event that fits? Thanks waco

• Dual Inspection / Four Eyes Principle

  - by Ralf

  I have the requirement to implement some kind of dual inspection or four-eyes principle as a feature of my software, meaning that every change of an object done by user A has to be checked by user B. A trivial example would be a publishing system where an author writes an article and another has to proofread it before it is published. I am a little bit surprised that you find nearly nothing about it on the net. No patterns, no libraries (besides cibet), no workflow solutions etc. Is this requirement really so uncommon? Or am I searching for the wrong terms? I am not looking for a specific solution. More for a pattern or best practice approach. Update: the above example is really trivial. Let's add some more complexity to it. The article has been published, but it now needs an update. Putting the article offline for the update is not an option, but the update has to be proof read, too.

• The First Microsoft Dynamics NAV Builds on TFS 2010 Server

  - by ssmantha

  We are now successfully, able build Dynamics NAV solutions using the TFS Build workflow mechanisms. Lots of test builds were made, the builds can restore the NAV Database and start from a fresh solution, take latest of the NAV objects and then import it to Navision and call the compile method. The workflow is also able to generate FOB files as output which can be directly shipped to the customers. I think this is the First in the world implementation of the TFS build concepts in conjunction with NAV. I think this is a time to change the thinking caps and try to approach ERP development and include the practises of ALM into ERP Product Development.

• WIF, ADFS 2 and WCF&ndash;Part 5: Service Client (more Flexibility with WSTrustChannelFactory)

  - by Your DisplayName here!

  See the previous posts first. WIF includes an API to manually request tokens from a token service. This gives you more control over the request and more flexibility since you can use your own token caching scheme instead of being bound to the channel object lifetime. The API is straightforward. You first request a token from the STS and then use that token to create a channel to the relying party service. I’d recommend using the WS-Trust bindings that ship with WIF to talk to ADFS 2 – they are pre-configured to match the binding configuration of the ADFS 2 endpoints. The following code requests a token for a WCF service from ADFS 2: private static SecurityToken GetToken() {     // Windows authentication over transport security     var factory = new WSTrustChannelFactory(         new WindowsWSTrustBinding(SecurityMode.Transport),         stsEndpoint);     factory.TrustVersion = TrustVersion.WSTrust13;       var rst = new RequestSecurityToken     {         RequestType = RequestTypes.Issue,         AppliesTo = new EndpointAddress(svcEndpoint),         KeyType = KeyTypes.Symmetric     };       var channel = factory.CreateChannel();     return channel.Issue(rst); } Afterwards, the returned token can be used to create a channel to the service. Again WIF has some helper methods here that make this very easy: private static void CallService(SecurityToken token) {     // create binding and turn off sessions     var binding = new WS2007FederationHttpBinding(         WSFederationHttpSecurityMode.TransportWithMessageCredential);     binding.Security.Message.EstablishSecurityContext = false;       // create factory and enable WIF plumbing     var factory = new ChannelFactory<IService>(binding, new EndpointAddress(svcEndpoint));     factory.ConfigureChannelFactory<IService>();       // turn off CardSpace - we already have the token     factory.Credentials.SupportInteractive = false;       var channel = factory.CreateChannelWithIssuedToken<IService>(token);       channel.GetClaims().ForEach(c =>         Console.WriteLine("{0}\n {1}\n  {2} ({3})\n",             c.ClaimType,             c.Value,             c.Issuer,             c.OriginalIssuer)); } Why is this approach more flexible? Well – some don’t like the configuration voodoo. That’s a valid reason for using the manual approach. You also get more control over the token request itself since you have full control over the RST message that gets send to the STS. One common parameter that you may want to set yourself is the appliesTo value. When you use the automatic token support in the WCF federation binding, the appliesTo is always the physical service address. This means in turn that this address will be used as the audience URI value in the SAML token. Well – this in turn means that when you have an application that consists of multiple services, you always have to configure all physical endpoint URLs in ADFS 2 and in the WIF configuration of the service(s). Having control over the appliesTo allows you to use more symbolic realm names, e.g. the base address or a completely logical name. Since the URL is never de-referenced you have some degree of freedom here. In the next post we will look at the necessary code to request multiple tokens in a call chain. This is a common scenario when you first have to acquire a token from an identity provider and have to send that on to a federation gateway or Resource STS. Stay tuned.

• Get aggregated view of data for entire website with Google Analytics

  - by crmpicco

  I have a website (www.ayrshireminis.com), which has three main sections under different directories, these are: /forum /galleries /contact I would like to have an aggregated view of the data for the whole website, but also for each section. What is the recommended approach for doing this? I believe I can create a web property that includes a profile for the entire website and duplicated filtered profiles, each section having an include filter. This is my gut instinct, but i'd like to know if there is another (better) way to do it? Maybe by having one account that includes a profile for the whole site and another profile with an include filter for the individual sections?

• How to encrypt php folder under /var/www?

  - by sirchaos

  I need to encrypt the folder /var/www/test. The folder contains PHP files. The goal it to prevent any user to read the php content AND if the HD is mounted on another computer, the /var/www/test should be encrypted AND if computer booted up without any user logged I would like anyone to be able to access data in /var/www/tests. What is the correct approach for this? I've tried "ecryptfs-setup-private" as advised in How to encrypt /var/www? yet it didn't work for me. I've might missed something - I've tested the folders while booting with ubuntu 12.04 installation disk and mounted the drive, than I was able to access /var/www/test content.. yet this is what I want to prevent. The gnome-encfs isn't the way to go since its decryption happens when users logs on to the system & I would like the system to be working after power failure etc' without any one logged in. Please advice.

• Sweet and Sour Source Control

  A recent survey on SQL Server Central showed that most database developers don't use Source Control. At first glance, it's a surprising thought. Unfortunately, the survey didn't ask about the scale of the database development. If there is only one database developer within a schema, who has an automated approach to regular generation of build scripts, then the need for a formal source control system is questionable....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Figuring a max repetitive sub-tree in an object tree

  - by bonomo

  I am trying to solve a problem of finding a max repetitive sub-tree in an object tree. By the object tree I mean a tree where each leaf and node has a name. Each leaf has a type and a value of that type associated with that leaf. Each node has a set of leaves / nodes in certain order. Given an object tree that - we know - has a repetitive sub-tree in it. By repetitive I mean 2 or more sub-trees that are similar in everything (names/types/order of sub-elements) but the values of leaves. No nodes/leaves can be shared between sub-trees. Problem is to identify these sub-trees of the max height. I know that the exhaustive search can do the trick. I am rather looking for more efficient approach.

• Modern.IE VM license

  - by Thomas W.

  Microsoft provides some VMs for testing purposes (advertised on StackOverflow) and I'm trying to understand the license terms. The one I don't really understand is 1.b. You may use the software for testing purposes only. You may not use the software for commercial purposes. My thoughts: a) Testing a website in several browsers on several different virtual machines seems a quite professional approach. I hardly believe many private developers would do that. Of course they should, but which private developer has the time to do so? b) If that's really only available to private developers, what is the offer to companies doing the same thing? I am missing the advertisement for a paid service. My question as a non-native English speaker: Is testing by a company considered as a commercial purpose? Can I use the VMs within a company for testing or not?

• What simple techniques do you use to improve performance?

  - by Cristian

  I'm talking about the way we write simple routines in order to improve performance without making your code harder to read... for instance, this is the typical for we learned: for(int i = 0; i < collection.length(); i++ ){ // stuff here } But, I usually do this when a foreach is not applicable: for(int i = 0, j = collection.length(); i < j; i++ ){ // stuff here } I think this is a better approach since it will call the length method once only... my girlfriend says it's cryptic though. Is there any other simple trick you use on your own developments?
