• Stored procedure Naming conventions?

  - by Chris

  One of our senior developers has stated that we should be using a naming convention for stored procedures with an "objectVerb" style of naming such as ("MemberGetById") instead of a "verbObject" type of naming ("GetMemberByID"). The reasoning for this standard is that all related stored procedures would be grouped together by object rather than by the action. While I see the logic for this way of naming things, this is the first time that I have seen stored procedures named this way. My opinion of the naming convention is that the name can not be read naturally and takes some time to determine what the words are saying and what the procedure might do. What are your takes on this? Which way is the more common way of naming a stored proc, and does a what types of stored proc naming conventions have you used or go by?

• Most efficient way to rebuild a tree structure from data

  - by Ahsan

  Have a question on recursively populating JsTree using the .NET wrapper available via NuGet. Any help would be greatly appreciated. the .NET class JsTree3Node has a property named Children which holds a list of JsTree3Nodes, and the pre-existing table which contains the node structure looks like this NodeId ParentNodeId Data AbsolutePath 1 NULL News /News 2 1 Financial /News/Financial 3 2 StockMarket /News/Financial/StockMarket I have a EF data context from the the database, so my code currently looks like this. var parentNode = new JsTree3Node(Guid.NewGuid().ToString()); foreach(var nodeItem in context.Nodes) { parentNode.Children.Add(nodeItem.Data); // What is the most efficient logic to do this recursively? } as the inline comment says in the above code, what would be the most efficient way to load the JStree data on to the parentNode object. I can change the existing node table to suite the logic so feel free to suggest any changes to improve performance.

• Resources for improving your comprehension of recursion?

  - by Andrew M

  I know what recursion is (when a patten reoccurs within itself, typically a function that calls itself on one of its lines, after a breakout conditional... right?), and I can understand recursive functions if I study them closely. My problem is, when I see new examples, I'm always initially confused. If I see a loop, or a mapping, zipping, nesting, polymorphic calling, and so on, I know what's going just by looking at it. When I see recursive code, my thought process is usually 'wtf is this?' followed by 'oh it's recursive' followed by 'I guess it must work, if they say it does.' So do you have any tips/plans/resources for building up your skills in this area? Recursion is kind of a wierd concept so I'm thinking the way to tackle it may be equally wierd and inobvious.

• Design Patterns - Why the need for interfaces?

  - by Kyle Johnson

  OK. I am learning design patterns. Every time I see someone code an example of a design pattern they use interfaces. Here is an example: http://visualstudiomagazine.com/Articles/2013/06/18/the-facade-pattern-in-net.aspx?Page=1 Can someone explain to me why was the interfaces needed in this example to demonstrate the facade pattern? The program work if you pass in the classes to the facade instead of the interface. If I don't have interfaces does that mean

• Web Developer or Web Designer

  - by user1702801

  I have built 10+ straightforward websites using the Symfony framework and Wordpress. Does this mean I am a web developer or a web designer? I set the sites up in Symfony and wrote the CSS/Javascript/HTML. I had to write themes for Wordpress and move some code about. What experience do I need to to be a web developer and not a designer? What experience distinguishes me from a designer that knows HTML and jQuery?

• How does TDD address interaction between objects?

  - by Gigi

  TDD proponents claim that it results in better design and decoupled objects. I can understand that writing tests first enforces the use of things like dependency injection, resulting in loosely coupled objects. However, TDD is based on unit tests - which test individual methods and not the integration between objects. And yet, TDD expects design to evolve from the tests themselves. So how can TDD possibly result in a better design at the integration (i.e. inter-object) level when the granularity it addresses is finer than that (individual methods)?

• Architecting multi-model multi-DB ASP.NET MVC solution

  - by A. Murray

  I have an ASP.NET MVC 4 solution that I'm putting together, leveraging IoC and the repository pattern using Entity Framework 5. I have a new requirement to be able to pull data from a second database (from another internal application) which I don't have control over. There is no API available unfortunately for the second application and the general pattern at my place of work is to go direct to the database. I want to maintain a consistent approach to modeling the domain and use entity framework to pull the data out, so thus far I have used Entity Framework's database first approach to generate a domain model and database context over the top of this. However, I've become a little stuck on how to include the second domain model in the application. I have a generic repository which I've now moved out to a common DataAccess project, but short of creating two distinct wrappers for the generic repository (so each can identify with a specific database context), I'm struggling to see how I can elegantly include multiple models?

• How do you prefer to handle image spriting in your web projects?

  - by Macy Abbey

  It seems like these days it is pretty much mandatory for web applications to sprite images if they want many images on their site AND a fast load time. (Spriting is the process of combining all images referenced from a style sheet into one/few image(s) with each reference containing a different background position.) I was wondering what method of implementing sprites you all prefer in your web applications, given that we are referring to non-dynamic images which are included/designed by the programming team and not images which are dynamically uploaded by a third party. 1. Add new images to an existing sprite by hand, create new css reference by hand. 2. Generate a sprite server-side from your css files which all reference single images set to be background images of an html element that is the same size of the image you are spriting once per build and update all css references programmatically. 3. Use a sprite generating program to generate a sprite image for you once per release and hand insert the new css class / image into your project. 4. Other methods? I prefer two as it requires very little hand-coding and image editing.

• TDD with limited resources

  - by bunglestink

  I work in a large company, but on a just two man team developing desktop LOB applications. I have been researching TDD for quite a while now, and although it is easy to realize its benefits for larger applications, I am having a hard time trying to justify the time to begin using TDD on the scale of our applications. I understand its advantages in automating testing, improving maintainability, etc., but on our scale, writing even basic unit tests for all of our components could easily double development time. Since we are already undermanned with extreme deadlines, I am not sure what direction to take. While other practices such as agile iterative development make perfect since, I am kind of torn over the productivity trade-offs of TDD on a small team. Are the advantages of TDD worth the extra development time on small teams with very tight schedules?

• Python C API return more than one value / object

  - by Grisu

  I got the following problem. I have written a C-Extension to Python to interface a self written software library. Unfortunately I need to return two values from the C function where the last one is optional. In Python the equivalent is def func(x,y): return x+y, x-y test = func(13,4) #only the first value is used In my C extension I use return Py_BuildValue("ii",x+y,x-y); which results in a tuple. If I now try to access the return value from Python via test2 = cfunc(13,4) print(test2) I got a tuple instead of only the first return value. How is possible to build the same behavior as in Python from C Extension?

• Highly scalable and dynamic "rule-based" applications?

  - by Prof Plum

  For a large enterprise app, everyone knows that being able to adjust to change is one of the most important aspects of design. I use a rule-based approach a lot of the time to deal with changing business logic, with each rule being stored in a DB. This allows for easy changes to be made without diving into nasty details. Now since C# cannot Eval("foo(bar);") this is accomplished by using formatted strings stored in rows that are then processed in JavaScript at runtime. This works fine, however, it is less than elegant, and would not be the most enjoyable for anyone else to pick up on once it becomes legacy. Is there a more elegant solution to this? When you get into thousands of rules that change fairly frequently it becomes a real bear, but this cannot be that uncommon of a problem that someone has not thought of a better way to do this. Any suggestions? Is this current method defensible? What are the alternatives? Edit: Just to clarify, this is a large enterprise app, so no matter which solution works, there will be plenty of people constantly maintaining its rules and data (around 10). Also, The data changes frequently enough to say that some sort of centralized server system is basically a must.

• Leading an offshore team

  - by Chuck Conway

  I'm in a position where I am leading two teams of 4. Both teams are located in India. I am on the west coast of the U.S. I'm finding leading remote teams challenging: First, their command of the English language is weak. Second, I'm having difficultly understanding them through their accents. Third is timing, we are 12 hours apart. We use Skype to communicate. I have a month to get the project done. We've burned through a week just setting up the environments. At this point I'm considering working their hours, 11p PDT to 7a PDT, to get them up to speed, so that I can get the project off the ground. A 12 hour lag time is too much. I'm looking for steps I can take to be successful at leading an offshore team. Update The offshore team's primary task is coding, of course, most coding tasks do involve some design work. The offshore team's are composed of one lead, 2 mid level (4 to 5 years) developers and a junior (~2 years) developer. The project is classic waterfall. We've handed the offshore team a business and a technical design document. We are trying to manage the offshore in an agile way. We have daily conference calls with them and I'm requiring the teams to send me a daily scrum in the form of an email answering the following questions: What did I do today? What am I going to do tomorrow? What do I need from Chuck so I can do my job tomorrow? There is some ambiguity in the tasks. The intent was to give them enough direction for them to develop the task with out writing the code for them. I don't have a travel budget. I am using Fogbugz to track the tasks. Each task has been entered into Fogbugz and given a priority. Each team member has access to FogBugz and can choose what task they wish to complete. Related question: What can we do to improve the way outsourcing/offshoring works? Update 2 I've decided that I can not talk to the team once a day. I must work with them. Starting tonight I've started working the same hours they are. This makes me available to them when they have questions. It also allows me to gain their trust and respect.

• Strategy for restoring state via URL in web apps

  - by JW01

  This is a question about modern web apps, where a single page is loaded, and all subsequent navigation is done by XHR calls and modifying the DOM. We can use libraries that manipulate the hash string, which let us navigate by URL and support the back/forward buttons. But to use those libraries, we need to be able to move the UI from any one state to any other. Is there a good strategy for moving between UI states, that also allows them to be restored from scratch when you load a new URL? In a complex app, you might have a lot of different states. You don't want to reload the entire UI each time you change states. But you also don't want to require separate methods for moving from every state to each every state. Typically we need to: Restore a state from scratch, when you enter a new URL or hit Reload. Move from one state to another, when you use the Back/Forward buttons. Move from one state to another, when you perform an action within your app (like clicking a link). Move to certain states that shouldn't be added to the history, like ones that appear after form submissions. Move to some states that are built on the previous state, like a drill-down list. When you perform actions within your app, there's the additional question of which comes first: Do you change the URL, listen for the URL change, and change your state in response to it? Or do you change your state, then change the URL, but don't do anything in response? Does anyone have some experience to share on this topic?

• Question on design of current pagination implementations

  - by Freshblood

  I have checked pagination implementations on asp.net mvc specifically and i really feel that there is something less efficient in implementations. First of all all implementations use pagination values like below. public ActionResult MostPopulars(int pageIndex,int pageSize) { } The thing that i feel wrong is pageIndex and pageSize totally should be member of Pagination class otherwise this way looks so much functional way. Also it simplify unnecesary paramater pass in tiers of application. Second thing is that they use below interface. public interface IPagedList<T> : IList<T> { int PageCount { get; } int TotalItemCount { get; } int PageIndex { get; } int PageNumber { get; } int PageSize { get; } bool HasPreviousPage { get; } bool HasNextPage { get; } bool IsFirstPage { get; } bool IsLastPage { get; } } If i want to routing my pagination to different action so i have to create new view model for encapsulate action name in it or even controller name. Another solution can be that sending this interfaced model to view then specify action and controller hard coded in pager method as parameter but i am losing totally re-usability of my view because it is strictly depends on just one action. Another thing is that they use below code in view Html.Pager(Model.PageSize, Model.PageNumber, Model.TotalItemCount) If the model is IPagedList why they don't provide an overload method like @Html.Pager(Model) or even better one is @Html.Pager(). You know that we know model type in this way. Before i was doing mistake because i was using Model.PageIndex instead of Model.PageNumber. Another big issue is they strongly rely on IQueryable interface. How they know that i use IQueryable in my data layer ? I would expected that they work simply with collections that is keep pagination implementation persistence ignorant. What is wrong about my improvement ideas over their pagination implementations ? What is their reason to not implement their paginations in this way ?

• Can I use access used by Visual Basic for building a database [on hold]

  - by user3413537

  I am the only programmer where I work (summer job) and I am a student with only a few years of programming experience. So I was asked to build a database and I am very excited about this project because hopefully I can learn a lot from this. Using this database my manager is supposed to be able to assign work (dealing with businesses) to different people within the company using an interface (all workers have a shared drive). When workers are done with that paperwork related to the business, they can check off that its done, add comments at the bottom of the interface, and then move on to the next business. The only experience I've had with databases is some querying with SQL, and I've built GUI interfaces with JAVA. The information on the interface will be populated from Excel so workers know what businesses they are dealing with. I've done some research and I believe the best way to build this would be building a GUI using Microsoft Visual Studio (Visual Basic) first, then figuring out a way to populate the Interface from Excel. Also because the data is pretty straight forward and not complicated I will be using MS Access to store and track the database. I know this won't be easy, but for all you geniuses out there, is this on the right path? Thanks.

• Good ruby book with exercises? [closed]

  - by watabou

  I find that I learn the best with a book that has a number of exercises at the end of each chapters. A great example of this is C++ Primer Plus by Stephen Prata or Scientific Programming with Python or the Horstmann Java books. All of those books have a number of programming exercises at the end tailored to that specific chapter. I love the styles of those book and was wondering if there is anything similar for Ruby. I've extensively searched google for this and people have been suggesting different stuff like different websites like Ruby Koans and LRTHW but honestly, I've tried those and they aren't for me. I taught myself Python with the the Hard Way book and to be honest, it's not for me. Now, forgive me if I'm blunt but does anyone have a Ruby programming BOOK (i.e. not a website), that has EXERCISES in it? I do NOT want a website, unless the book is only or is freely available online by the author, similar to the Hard Way books. I would say that I'm a intermediate level programmer with only some Ruby experience but if you know of a beginner book on Ruby, that is fine too. Thanks in advance, I would really really appreciate the help.

• When should we use weak entities when modelling a database?

  - by Songo

  This is basically a question about what are weak entities? When should we use them? How should they be modeled? What is the main difference between normal entities and weak entities? Does weak entities correspond to value objects when doing Domain Driven Design? To help keep the question on topic here is an example taken from Wikipedia that people can use to answer these question: In this example OrderItem was modeled as a weak entity, but I can't understand why it can't be modeled as a normal entity. Another question is what if I want to track the order history (i.e. the changes in it status) would that be a normal or weak entity?

• Need help on implementing corporate network security solution and coming up with time lines to test it

  - by abc

  I have to come up with a proposal to implement corporate network security. Once I have done that I also have to come up with estimates on the time / money needed to test (QA) the implementation. What I need help with: What should I keep in mind while coming up with this proposal? I have already considered: Routers, Firewalls, VPN, Wireless, Server System, Web Apps etc. I know I am missing quite a lot. What else should I include? This the most challenging part I feel: How should I estimate the time needed for testing these security implementations? I guess I need to understand how can I test these security implementations first...right? Can you help me?

• When to use abstract classes instead of interfaces and extension methods in C#?

  - by Gulshan

  "Abstract class" and "interface" are similar type of ideas, while interface being more abstract. One need of abstract classes was to provide method implementations for the derived classes. But in C#, that need has also been reduced by lately introduced extension methods. So, in C#, when should we use abstract classes instead of using interfaces and extension methods associated with the interface? And now, we can use 'Properties' in interfaces also. A notable example of interface+ extension methods is the Heavily used IEnumerable and it's helper methods. You use Linq and it's all by this extension methods!

• What happened to GremCheck? Is there a viable replacement?

  - by goober

  I was a big fan of an app called "GremCheck" that was out a while back, that seems to have disappeared. It was a JavaScript included in a master page that placed an icon at the bottom of the page. It was used during testing. You could define your own tests, and the box could pop up per page and viewers would answer the questions you define (such as "Does this page have the correct title?", "Is the Grammar Correct", "Does the design look consistent"). This was useful for end-user tests groups and quick testing for developers if time was squeezed on full functional testing. Anyone know where GremCheck went, if I can get to it, and if there's anything out there that does something similar?

• Programming in the United States Airforce - How hard to get a job doing it? [closed]

  - by Holland

  I already know how to program. Been at it for a year; the language I've worked mostly with has been C++, and I'm currently studying x86 assembly programming, with the goal to move towards ARM assembly after I've finished with that. Thus, given my experience and knowledge, I'm curious to know if any "vets" around here have had any excursions in the military doing software/electrical engineering, and how hard it would be to actually get a job doing it - with someone who already has previous experience and knowledge regarding that field, however slight. By definition of "hard", in this context, I suppose I'd be referring to the required knowledge to actually be a "shoe-in" for both low level and high level software/hardware applications. I know hex fairly well, and enough to convert that hex to binary. I also have an ok knowledge of algorithms, such as Binary Search Tree, Linked List, etc. Everything I've learned so far has been self taught for the most part.

• Single Responsibility Principle - How Can I Avoid Code Fragmentation?

  - by Dean Chalk

  I'm working on a team where the team leader is a virulent advocate of SOLID development principles. However, he lacks a lot of experience in getting complex software out of the door. We have a situation where he has applied SRP to what was already quite a complex code base, which has now become very highly fragmented and difficult to understand and debug. We now have a problem not only with code fragmentation, but also encapsulation, as methods within a class that may have been private or protected have been judged to represent a 'reason to change' and have been extracted to public or internal classes and interfaces which is not in keeping with the encapsulation goals of the application. We have some class constructors which take over 20 interface parameters, so our IoC registration and resolution is becoming a monster in its own right. I want to know if there is any 'refactor away from SRP' approach we could use to help fix some of these issues. I have read that it doesn't violate SOLID if I create a number of empty courser-grained classes that 'wrap' a number of closely related classes to provide a single-point of access to the sum of their functionality (i.e. mimicking a less overly SRP'd class implementation). Apart from that, I cannot think of a solution which will allow us to pragmatically continue with our development efforts, while keeping everyone happy. Any suggestions ?

• What do you do before you start programming?

  - by SterAllures

  Heya, I'm not sure this question belongs here, it's not so much I problem I'm having with programming but rather a problem of what to do before I start programming. I want a visual representation of what variables I need and what classes have what methods.I know there is UML but I'm not sure if that is the best way, so what do you guys use before you start programming, which method? I don't want to start a flamewar about what is better just what are several approaches?
