• How to make NFS mounts available while offline?

  - by lpanebr

  Problem: I work on a notebook and while at work I have access to many NFS mounted drives. When I get home they are obviously not available. Windows 7 solution: My business partner uses Windows 7 and maps the folders via samba. Windows 7 has a very nice feature that let's he make these folders available offline. So when when he connects to the work network the changes get synchronized! Question: Is there a way to mimic that in ubuntu? What I have now: Server to local sync: I have added rsync entries on my crontab to copy server folders => local folders every five minutes. When at work I used the NFS mapped folders and while outside work I use the local copies. When I get at work I manually run a script that syncs local folders => server folders. Problems with my setup: slow startup when not at work (I guess do to the fstab trying to map the server folders) no conflict checking/managing I have to remember to sync manually and be careful because of the different file locations recent files do not work between work and home

• When decomposing a large function, how can I avoid the complexity from the extra subfunctions?

  - by missingno

  Say I have a large function like the following: function do_lots_of_stuff(){ { //subpart 1 ... } ... { //subpart N ... } } a common pattern is to decompose it into subfunctions function do_lots_of_stuff(){ subpart_1(...) subpart_2(...) ... subpart_N(...) } I usually find that decomposition has two main advantages: The decomposed function becomes much smaller. This can help people read it without getting lost in the details. Parameters have to be explicitly passed to the underlying subfunctions, instead of being implicitly available by just being in scope. This can help readability and modularity in some situations. However, I also find that decomposition has some disadvantages: There are no guarantees that the subfunctions "belong" to do_lots_of_stuff so there is nothing stopping someone from accidentally calling them from a wrong place. A module's complexity grows quadratically with the number of functions we add to it. (There are more possible ways for things to call each other) Therefore: Are there useful convention or coding styles that help me balance the pros and cons of function decomposition or should I just use an editor with code folding and call it a day? EDIT: This problem also applies to functional code (although in a less pressing manner). For example, in a functional setting we would have the subparts be returning values that are combined in the end and the decomposition problem of having lots of subfunctions being able to use each other is still present. We can't always assume that the problem domain will be able to be modeled on just some small simple types with just a few highly orthogonal functions. There will always be complicated algorithms or long lists of business rules that we still want to correctly be able to deal with. function do_lots_of_stuff(){ p1 = subpart_1() p2 = subpart_2() pN = subpart_N() return assembleStuff(p1, p2, ..., pN) }

• Classes as a compilation unit

  - by Yannbane

  If "compilation unit" is unclear, please refer to this. However, what I mean by it will be clear from the context. Edit: my language allows for multiple inheritance, unlike Java. I've started designing+developing my own programming language for educational, recreational, and potentially useful purposes. At first, I've decided to base it off Java. This implied that I would have all the code be written inside classes, and that code compiles to classes, which are loaded by the VM. However, I've excluded features such as interfaces and abstract classes, because I found no need for them. They seemed to be enforcing a paradigm, and I'd like my language not to do that. I wanted to keep the classes as the compilation unit though, because it seemed convenient to implement, familiar, and I just liked the idea. Then I noticed that I'm basically left with a glorified module system, where classes could be used either as "namespaces", providing constants and functions using the static directive, or as templates for objects that need to be instantiated ("actual" purpose of classes in other languages). Now I'm left wondering: what are the benefits of having classes as compilation units? (Also, any general commentary on my design would be much appreciated.)

• Content light website and Google - Tell google it's a listings site (as opposed shop, reviews or restaurants)

  - by Doug Firr

  I have a listings style website. Due to the nature of this (listings) the site is content light. Each page is typically less that 50 words but there are many pages. The site in question has had a ton of media coverage and so has some great inbound links from places like Wired, Fast Company, Canada Broadcasting Corporation and many many other bloggers, media websites and recycle related niche authors (It's a recycling site). But Google really ignores it. Traffic from search is very very low - less than 5% of all traffic. I know that using markup you can tell Google whether your site is a restaurant, article, review, shop, local business and a few other categories (https://www.google.com/webmasters/markup-helper/u/0/). Is there a way to tell Google that my site is a listings site? I suspect, but do not know for sure, that part of the problem is that Google simply does not know what my site is? It's a crowdmap where people post curbalerts. The information is useful to people but it is presented in a short, concise way - a pin on a map, a picture and a short description. Adding anything further is not necessary for the site's intended purpose. 1st question - how best to tell the search engines what y site is - listings and not some spammy website? Any recommendations in improving our site's Search presence? You can take a look here if interested: http://tinyurl.com/lxg4hn7

• How to choose between Tell don't Ask and Command Query Separation?

  - by Dakotah North

  The principle Tell Don't Ask says: you should endeavor to tell objects what you want them to do; do not ask them questions about their state, make a decision, and then tell them what to do. The problem is that, as the caller, you should not be making decisions based on the state of the called object that result in you then changing the state of the object. The logic you are implementing is probably the called object’s responsibility, not yours. For you to make decisions outside the object violates its encapsulation. A simple example of "Tell, don't Ask" is Widget w = ...; if (w.getParent() != null) { Panel parent = w.getParent(); parent.remove(w); } and the tell version is ... Widget w = ...; w.removeFromParent(); But what if I need to know the result from the removeFromParent method? My first reaction was just to change the removeFromParent to return a boolean denoting if the parent was removed or not. But then I came across Command Query Separation Pattern which says NOT to do this. It states that every method should either be a command that performs an action, or a query that returns data to the caller, but not both. In other words, asking a question should not change the answer. More formally, methods should return a value only if they are referentially transparent and hence possess no side effects. Are these two really at odds with each other and how do I choose between the two? Do I go with the Pragmatic Programmer or Bertrand Meyer on this?

• Case studies for successful service (project) based software development businesses without constant overtime from its employees [closed]

  - by Ryan Taylor

  I work for an IT company that is primarily services (project) based rather than product based. All software engineers are salaried. The company has set new expectations that everyone should work 48 hours per week instead of 40. Note, this isn't occasional overtime due to crunches. This is the new 40. The reasoning is that this enables the company to provide benefits to its employees such as monetary incentives and training because the company is more profitable. more hours worked = more billable hours = larger profit I understand the need for profitability and the occasional crunch time and have put in the extra hours when it was needed and beneficial to the project. However, I am also very sensitive to work life balance and have raised my concerns about the the new expectation. My employer is open to other methods to increase profitability so I hold hope that we can turn things around before it becomes a horrible place to work. How does a services based company become more profitable without increasing the number of hours expected from it's salaried employees? Are there any case studies showing the pros and cons of consistent overtime? Are there any case studies for a successful service based business model (for software development companies) that does not require consistent overtime from its employees?

• Achieve anisotropic filtering

  - by fedab

  I want to set anisotropic filtering to my scene. I use SharpDX (DirectX 11) and C#. How do i set up anisotropic filtering in my shader? Currently i try that in the shader: Texture2D tex; sampler textureSampler = sampler_state { Texture = (tex); MipFilter = Anisotropic; MagFilter = Anisotropic; MinFilter = Anisotropic; MaxAnisotropy = 16; }; float4 PShader(float4 position : SV_POSITION, float4 color:COLOR, float2 tex0 : TEXCOORD0) : SV_TARGET { float4 textureColor; textureColor = tex.Sample(textureSampler, tex0) * color; return textureColor; } I get my object, textured, but it is not filtered anisotropic. I can write everything in the Parameters, even invalid things and i don't get any errors. The result is the same, objects without applied anisotropic filtering. Do i have to set that in the shader? Can i do that also with SamplerState? I tested that but i didn't get a result too. Some steps what i have to set would be helpful.

• Are super methods in JavaScript limited to functional inheritance, as per Crockford's book?

  - by kindohm

  In Douglas Crockford's "JavaScript: The Good Parts", he walks through three types of inheritance: classical, prototypal, and functional. In the part on functional inheritance he writes: "The functional pattern also gives us a way to deal with super methods." He then goes on to implement a method named "superior" on all Objects. However, in the way he uses the superior method, it just looks like he is copying the method on the super object for later use: // crockford's code: var coolcat = function(spec) { var that = cat(spec), super_get_name = that.superior('get_name'); that.get_name = function (n) { return 'like ' + super_get_name() + ' baby'; }; return that; }; The original get_name method is copied to super_get_name. I don't get what's so special about functional inheritance that makes this possible. Can't you do this with classical or prototypal inheritance? What's the difference between the code above and the code below: var CoolCat = function(name) { this.name = name; } CoolCat.prototype = new Cat(); CoolCat.prototype.super_get_name = CoolCat.prototype.get_name; CoolCat.prototype.get_name = function (n) { return 'like ' + this.super_get_name() + ' baby'; }; Doesn't this second example provide access to "super methods" too?

• MVC design patterns

  - by insane-36

  I have an application and it does not use a very good structure. However it seems to me that I have tried to stick to mvc design pattern but a senior engineer claims that I have no design patterns and code are mesh. How I have structured the code : I have couple of nsmanagedobject model classes which represents model in my case and a reskit library which encapsulates the nsurlconnection and url request. I fetch the request from the view controller itself and then when the request get completed I create predicate and then populate it in tableview. Wherever I need custom view either I create it in nib or create in a custom subclass of UIView. I have use delegation pattern and notification to communication to view controller, views and block callback with restkit. But, the senior engineer is very new to ios. He has been doing it for 2 months now but he is a good java programmer. So, what is mvc pattern ? Is core data model not working as a model objects, view controller as controller and views. I dont seem to find any other places or any other cases to create my own model object since the most of the models are used as NSManagedObject subclass.

• Fast, accurate 2d collision

  - by Neophyte

  I'm working on a 2d topdown shooter, and now need to go beyond my basic rectangle bounding box collision system. I have large levels with many different sprites, all of which are different shapes and sizes. The textures for the sprites are all square png files with transparent backgrounds, so I also need a way to only have a collision when the player walks into the coloured part of the texture, and not the transparent background. I plan to handle collision as follows: Check if any sprites are in range of the player Do a rect bounding box collision test Do an accurate collision (Where I need help) I don't mind advanced techniques, as I want to get this right with all my requirements in mind, but I'm not sure how to approach this. What techniques or even libraries to try. I know that I will probably need to create and store some kind of shape that accurately represents each sprite minus the transparent background. I've read that per pixel is slow, so given my large levels and number of objects I don't think that would be suitable. I've also looked at Box2d, but haven't been able to find much documentation, or any examples of how to get it up and running with SFML.

• How do I find actors in an area on a poly-precise basis?

  - by Almo

  Ok, I've been asking various questions and getting some good answers, but I think I need to rethink my method, so I'll describe the problem. I have a player who has a big blue box in front of him. This box shows which KActors will be pushed when he pulls the trigger: Currently, the blue box spawns a descendant of Actor which checks collision to see which KActors are touching it: foreach Owner.TouchingActors(class'DynamicSMActor', DynamicActorItt) { // do stuff } The problem is, if you check for touching between Actors and KActors, it looks like it does a plain axis-aligned bounding-box collision. The power will push the box on the lower right, when it's clear it's not touching the blue box. How should I do this properly? I just need a way to find out which KActors are touching that area, on a poly-by-poly level. These collisions are only done with rectangular boxes and simple sphere collision; we are aware of the potential for performance issues with complex objects and poly-collision. I've tried making the collision checker a KActor, but it doesn't report any TouchingActors. This issue is causing us trouble in a lot of other places as well. So solving this problem is a core issue in our game.

• What's the point of the Prototype design pattern?

  - by user1905391

  So I'm learning about design patterns in school. Many of them are silly little ideas, but nevertheless solve some recurring problems(singleton, adapters, asynchronous polling, ect). But today I was told about the so called 'Prototype' design pattern. I must be missing something, because I don't see any benefits from it. I've seen people online say it's faster than using "new"' but this is doesn't make any sense, since at some point, regardless how the new object is created, memory needs to be allocated for it ect. Furthermore, doesn't this pattern run in the same circles as the 'chicken or egg' problem? By this I mean, since the prototype pattern essentially is just cloning objects, at some point the original object must be created itself (ie, not cloned). So this would mean, that I would need to have an existing copy of every object that I would ever want to clone already ready to clone? Seems stupid to me. Can anyone explain what the use of this pattern is? Original post: http://stackoverflow.com/questions/13887704/whats-the-point-of-the-prototype-design-pattern

• Noise Canceling Earphones

  - by Mark Treadwell

  I travel a lot. The hours spent droning through the sky can be made more tolerable with an MP3 player and a set of noise-cancelling headphones. Reducing the sound of the airflow and engines is a great relief. For a year or two, I used a pair of folding Sony MDR-NC5 Noise Canceling Headphones, the ear foam covers self-destructed. I replaced them with old washcloth material and was happy, but the DW thought it looked bad.  I switched to a new set of Sony MDR-NC6 Noise Canceling Headphones.  These worked equally well, although they did not fold as small as the MDR-NC5 headphones. Over four years of use, the MDR-NC6 headphones started cutting out and making popping noises.  This was not surprising considering the beating they took on travel in my backpack.  It looked like I needed another new set. The older MDR-NC5 headphones were still on the shelf with the hated washcloth covers.  A quick search online showed a vibrant business in selling replacement ear foams, often at exorbitant prices.  Nowhere did I see ear foam covers made for the oblong MDR-NC5.  I then realized that foam is stretchable and that the shape should not matter.  After another search and some consideration, I purchased 2-5/16" foam pad ear covers that were able to stretch over the MDR-NC5's strange shape.  Problem solved for less than $5.

• How to configure Bullet for LookAt?

  - by AllCoder

  I'm having problems positioning Bullet objects. I am doing: ToolVec3 origin = ToolVec3( obj_posx, obj_posy, obj_posz ); ToolVec3 vmod = ToolVec3( object_sizex / 2.0f, object_sizey / 2.0f, object_sizez / 2.0f ); btTransform shapeTransform = btTransform::getIdentity(); shapeTransform.setOrigin( btVector3(origin.x+vmod.x, origin.y+vmod.y, origin.z+vmod.z) ); btDefaultMotionState* myMotionState = new btDefaultMotionState(shapeTransform); btRigidBody::btRigidBodyConstructionInfo rbInfo(mass,myMotionState,m_collisionShapes[2],localInertia); btRigidBody* body = new btRigidBody(rbInfo); I then do: btCollisionObject* colObj = m_dynamicsWorld->getCollisionObjectArray()[i]; btRigidBody* body = btRigidBody::upcast(colObj); if(body && body->getMotionState()) { btDefaultMotionState* myMotionState = (btDefaultMotionState*)body->getMotionState(); myMotionState->m_graphicsWorldTrans.getOpenGLMatrix(m); } else { colObj->getWorldTransform().getOpenGLMatrix(m); } And after obtaining the matrix m, I paste it as model matrix. I am observing few things: I must add some weird "size / 2" to object's position, to have it drawed normally, I have following "up" look at vector defined: "0.0f, -1.0f, 0.0f" – basically, Y grows up, Z grows forward (to monitor), BUT – x grows LEFT, I think there is some conflict with the X direction.. I cannot obtain consistent positioning having world setup like this How to configure this in Bullet? Why the weird + size/2 requirement?

• What's wrong performing unit test against concrete implementation if your frameworks are not going to change?

  - by palm snow

  First a bit of background: We are re-architecting our product suite that was written 10 years ago and served its purpose. One thing that we cannot change is the database schema as we have 500+ client base using this system. Our db schema has over 150+ tables. We have decided on using Entity Framework 4.1 as DAL and still evaluating various frameworks for storing our business logic. I am investigation to bring unit testing into the mix but I also confused as to how far I need to go with setting up a full blown TDD environment. One aspect of setting up unit testing is by getting into implementing Repository, unit of work and mocking frameworks etc. This mean there will be cost and investment on the code-bloat associated with all these frameworks. I understand some of this could be auto-generated but when it comes to things like behaviors, that will be mostly hand written. Just to be clear, I am not questioning the important of unit testing your code. I am just not sure we need all its components (like repository, mocking etc.) when we are fairly certain of storage mechanism/framework (SQL Server/Entity Framework). All that code bloat with generic repositories make sense when you need a generic layers with ability to change this whenever you like however its very likely a YAGNI in our case. What we need is more of integration testing where we can unit-test our code with concrete repository objects and test data in database. In this scenario, just running integration test seem to be more beneficial in our case. Any thoughts if I am missing any thing here?

• Spend Analytics on a Grand Scale

  - by jacqueline.coolidge(at)oracle.com

  The Wall St. Journal reports in Billions in Bloat Uncovered in Beltway that a recent study by Government Accountability Office (GAO) has released a massive study of several programs and agencies that cost U.S. taxpayers billions of dollars each year.  This report help save $100 to $200 Billion dollars by identifying duplicate spending and ineffective programs that can be consolidated or eliminated. Now, that is spend analytics on a massive scale! It remains to be seen how actionable that information will be.  Certainly, there have been studies before that identify wasteful spending.  But, it’s a great case of the power of business intelligence and spend analytics.   Many companies do find significant savings when they implement spend and procurement analytics. What makes for an excellent spend analysis? It should be: Objective and provide visibility across programs and/or divisions A cross functional analysis that links financial with performance metrics Prescriptive and actionable Spend and procurement analytics have been HOT during the economic downturn! I expect 2011 will see many more companies get serious about spend analytics and would love to hear from companies who are willing to share their experience.

• Is it possible to keep only one Database for both web and desktop applications?

  - by B4NZ41

  I'm experiencing a trouble with my business model, let me explain better. I'm developing a software for 1 year and few months, it's for the food industry, more exactly a software to: Delivery, Take Way, Table Reservation, POS, Accounts Payable and Receivable, Prints(receipt), Kitchen Monitors Orders, Customers Orders Control and Fiscal Area. Well, I had separated the software mainly in two areas, one is web area and the other is desktop area (Used by Admins only) and local installed. 1 - Web Area (Basically do the follow:) Show Catalog with the products Customers Make Orders Customers Pay for the Orders etc ... as mentioned above 2 - Desktop Area Manage Orders Manage Customers Manage Suppliers Manage Accounts Payable and Receivable etc ... as mentioned above The web area is hosted in an online web server (scripts and database are online). The Desktop area is hosted locally in a Linux machine with a local database and local scripts files. My question is: Is it possible to keep only one Database for both applications? If YES, please what is the best approach? Follow my technical specification environment Database: Actually I have two databases working and I would love to keep only one. Operating System: Linux (Kernel 2.6.X and above) or Windows (XP and above) For the Web Area Apache, PHP, Python, Java Script, Shell Script and MySQL. For the Desktop Area: PHP-GTK2, Apache, PHP, MySQL and Shell Script.

• Problems moving a rectangle in Pygame.

  - by Yann Core

  Hi guys! I'm making a game in Pygame and I want to be able to target enemy unit. I made it so when I click on them a variable "targeted" becomes true, and stays true until I click somewhere else on the screen. I also want targeted units to have a small green circle around them, so I made it in GEDIT. I have made a function that draws everything on the screen (the background, the player, objects, etc) and in the part where it draws the units it checks if the variable "targeted" is true and if it is it should move that little green circle over the enemy units. here is the code that does that: screen.blit(enemy_unit.pic, enemy_unit.rect) #draw the unit if enemy_unit.targeted == True: #if the unit has been targeted then draw a circle over it target_rect.move_ip(enemy_unit.pos) #move the circle to the unit target_rect.fit(enemy_unit.rect) #there are some bigger units and some smaller ones, so we have to "scale" the circle screen.blit(target_pic, target_rect) #actually draw the circle This doesn't work, when I target the unit the circle just appears for a 1/5 of second next (not on, but just next) to the unit and then disappears. I am sure that I am keeping a good track of "enemy_unit.pos" because I tested it (I added a piece of code that would print one units position and mouse's position every time i clicked the mouse and when i was near him the numbers were same). If you could give me a hint about what I'm doing wrong. I think its in move_ip function, but I tried just move and it didn't work either (the circle didn't even show at all)!

• How can one find software development work that involves directly the final end user?

  - by RJa

  I've worked in software development for 15 years and, while there have been signficant personal achievements and a lot of experience, I've always felt detached from the man/woman-on-the-street, the every day person, how it affects their lives, in a number of ways: the technologies: embedded software, hidden away, stuff not seen by the everyday person. Or process technology supporting manufactured products the size of the systems, meaning many jobs, divided up, work is abstract, not one person can see the whole picture the organisations: large, with departments dealing with different areas, the software, the hardware, the marketing, the sales, the customer support the locations and hours: out-of-town business parks away from the rest of society, fixed locations, inflexible: 9-5 everyday This to me seems typical of the companies I worked for and see elsewhere. Granted, there are positives such as the technology itself and usually being among high calibre co-workers, but the above points frustrate me about the industry because they detach the work from its meaning. How can one: change these things in an existing job, or compensate for them? find other work that avoids these and connects with the final end user? Job designs tend to focus on the job content and technical requirements rather than how the job aims to fulfil end user needs, is meaningful.

• Applying for job: how to showcase work done for (private) past clients?

  - by user33445566

  I want to apply for my first "real" (read: non-freelance) Ruby on Rails job. I've built several apps already. My best work (also the most logically complicated app) was for a freelance client, and I'd like to show it to potential employers. Only problem is: it isn't online anymore. And I've lost touch with the client. How can I include this work in my portfolio? About the app: It's a Facebook game. The client's business idea for this app was not the best. It was never going to make any money. I think it was kind of a vanity side project for him. The logo and graphics are nice-looking, though, and were designed by the client. I've actually spent a lot of time recently recoding most of the app, and adding a full test suite. I want to showcase the BDD / TDD skills I've acquired. I'm not very familiar with the etiquette (/law?) concerning this situation. Can I just put my new version of the app up at a free Heroku URL (perhaps with a "credits" section, where I credit the ideas and graphic designs to my former client)? NOTE: Again, this is just to show potential employers. I am not trying to market the app as my idea, or attract any users. Can I put some or all of the code on GitHub? What if I don't put the code up publicly, but merely send a tarball to potential employers? Do I need to ask permission from my former client (and what if he says no)? The last thing I want to do is get in any legal trouble, or offend people I'm trying get a job from. But I believe that my work and experience on this app are my highest recommendation for getting a job.

• Why am I seeing so many instantiable classes without state?

  - by futlib

  I'm seeing a lot of instantiable classes in the C++ and Java world that don't have any state. I really can't figure out why people do that, they could just use a namespace with free functions in C++, or a class with a private constructor and only static methods in Java. The only benefit I can think of is that you don't have to change most of your code if you later decide that you want a different implementation in certain situations. But isn't that a case of premature design? It could be turned into a class later, when/if it becomes appropriate. Am I getting this wrong? Is it not OOP if I don't put everything into objects (i.e. instantiated classes)? Then why are there so many utility namespaces and classes in the standard libraries of C++ and Java? Update: I've certainly seen a lot examples of this in my previous jobs, but I'm struggling to find open source examples, so maybe it's not that common after all. Still, I'm wondering why people do it, and how common it is.

• Android Bitmap: Collision Detecting

  - by Aekasitt Guruvanich

  I am writing an Android game right now and I would need some help in the collision of the Pawns on screen. I figured I could run a for loop on the Player class with all Pawn objects on the screen checking whether or not Width*Height intersects with each other, but is there a more efficient way to do this? And if you do it this way, many of the transparent pixel inside the rectangular area will also be considered as collision as well. Is there a way to check for collision between Bitmap on a Canvas that disregard transparent pixels? The class for player is below and the Pawn class uses the same method of display. Class Player { private Resources res; // Used for referencing Bitmap from predefined location private Bounds bounds; // Class that holds the boundary of the screen private Bitmap image; private float x, y; private Matrix position; private int width, height; private float velocity_x, velocity_y; public Player (Resources resources, Bounds boundary) { res = resources; bounds = boundary; image = BitmapFactory.decodeResource(res, R.drawable.player); width = image.getWidth(); height = image.getHeight(); position = new Matrix(); x = bounds.xMax / 2; // Initially puts the Player in the middle of screen y = bounds.yMax / 2; position.preTranslate(x,y); } public void draw(Canvas canvas) { canvas.drawBitmap(image, position, null); } }

• Simplifying data search using .NET

  - by Peter

  An example on the asp.net site has an example of using Linq to create a search feature on a Music album site using MVC. The code looks like this - public ActionResult Index(string movieGenre, string searchString) { var GenreLst = new List<string>(); var GenreQry = from d in db.Movies orderby d.Genre select d.Genre; GenreLst.AddRange(GenreQry.Distinct()); ViewBag.movieGenre = new SelectList(GenreLst); var movies = from m in db.Movies select m; if (!String.IsNullOrEmpty(searchString)) { movies = movies.Where(s => s.Title.Contains(searchString)); } if (!string.IsNullOrEmpty(movieGenre)) { movies = movies.Where(x => x.Genre == movieGenre); } return View(movies); } I have seen similar examples in other tutorials and I have tried them in a real-world business app that I develop/maintain. In practice this pattern doesn't seem to scale well because as the search criteria expands I keep adding more and more conditions which looks and feels unpleasant/repetitive. How can I refactor this pattern? One idea I have is to create a column in every table that is "searchable" which could be a computed column that concatenates all the data from the different columns (SQL Server 2008). So instead of having movie genre and title it would be something like. if (!String.IsNullOrEmpty(searchString)) { movies = movies.Where(s => s.SearchColumn.Contains(searchString)); } What are the performance/design/architecture implications of doing this? I have also tried using procedures that use dynamic queries but then I have just moved the ugliness to the database. E.g. CREATE PROCEDURE [dbo].[search_music] @title as varchar(50), @genre as varchar(50) AS -- set the variables to null if they are empty IF @title = '' SET @title = null IF @genre = '' SET @genre = null SELECT m.* FROM view_Music as m WHERE (title = @title OR @title IS NULL) AND (genre LIKE '%' + @genre + '%' OR @genre IS NULL) ORDER BY Id desc OPTION (RECOMPILE) Any suggestions? Tips?
