    i'm a fan of ubuntu, but for now i want my installation to be perfect for my new laptop, its a series 5 of samsung with A6 processor. Somebody suggest what to do? or mention any problems related to this? Im more concern of the drivers to increase its performance because i am to develop an android app. I need "i dont know" to make this unit run as fast as possible without any dangerous tradeoffs. Also i read some forum saying that their units are overheating. -_- somebody help me please. and also i want to switch to gnome 3. And last thing, is there any differences in performance if i use alongside, replace or custom in formatting?

  • Design Patterns - Service Layer

    - by garfbradaz
    I currently reading a lot about Design Patterns and I have been watching various Pluralsight videos from their library. Now so far I have learnt the following: Repository Pattern Unit of Work Pattern Abstract Factory Pattern Reading the awesome "DI in .NET" book Now I read lot about Services and Service Layers and wanted some advice about the best place to read up and learn about these. I presume this fits into Domain Driven Design and I should start there? The term "Service" just seem to be used widely within IT and it can be confusing the exact meaning. So my questions is: What is the Service Layer Where is the best place to learn about them. I know there are probably tonnes of interweb/books/blogs on the subject, but some good areas to start from would be nice. If I'm being too vague, let me know.

  • Are VM-based languages becoming viable for Graphics since the move to GPU computing?

    - by skiwi
    Perhaps the title is not the most clear, so let me elaborate it more: I am talking about VM-based languages, by that I mean languages that run on the JVM (java) and for example C#. Also I am talking about 3D graphics, just to be clear. Lately the trend has been that most computing is being done on the GPU and not on the CPU, and since times the issue with programming games on a VM-based language is that garbage collecting may happen randomly. So let's take a look which is responsible for what: Showing the graphics: GPU Uploading graphics to the GPU: CPU? Needs to be done every frame? Calculating physics constraints: GPU Doing the real game logic (Determining when to move objects (independent of physics calculations), processing AI): CPU Is my list actually correct? And if it is, is for example Java becoming more viable? Or is uploading the graphics (vertices) still the most expensive operation? Would like to get more insight into this.

  • How do I decide to which class a method should belong

    - by Eleeist
    I have TopicBusiness.class and PostBusiness.class. I have no problem with deciding into which class methods such as addPostToDatabase() or getAllPostsFromDatabase() should go. But what about getAllPostsFromTopic(TopicEntity topic) or getNumberOfPostsInTopic(TopicEntity topic)? Should the parameter be the deciding factor? So when the method takes TopicEntity as parameter it should belong to TopicBusiness.class? I am quite puzzled by this. EDIT: Some more info as requested. TopicBusiness.class and PostBusiness.class are classes holding all the business logic of the application concerning topics and posts respectively - that is fetching the data from database and/or performing some operations on them. TopicEntity is data (in this case representing single topic) fetched from database. getAllPostFromTopic(TopicEntity topic) gets all posts from database that belong to particular topic, while getNumberOfPostsInTopic(TopicEntity topic) performs database query and returns the number of posts that topic passed as parameter consists of.

  • Listening For and Raising Events in the BLL

    - by OneSource
    I'm working on a WinForms .Net Recording App and I have a RecordingMgr in my BLL to listen for new events captured by another class. I want to display the events in my UI and I'm stuck as to what's the best way to do this. I can think of a few scenarios to handle this but all of them seem sub-optimal: Listen for and handle Recorded Events in both the UI and in the RecordingMgr After receiving the event in the RecordingMgr, raise it again so that the UI can pick it up Create a variable in RecordingMgr (e.g., a BindingList) that the UI can bind to and update it when an Event is received Ditch the RecordingMgr and just put the event recording logic in the UI What's the best approach? Something above or something else?

  • How to remove "Search and launch"?

    - by user38489
    Is it possible to remove the "Search and launch" whateveritis from my "desktop"? I've actually tried both Desktop and Netbook modes, but it stays there in both of them. I'm not afraid of editing files in the ~/.kde dir, but I would be really disappointed if this is the only way to do it. [more details/rants] I was able to wipe out several things but I've ended up with a black window that's movable (Alt-click) but not removable. Beside being surprised by the performances, I find Kubuntu extremely unfriendly, and I can't find the logic behind the items of the interface. I've tried to search for documentation, but what I've found is not updated and doesn't include the Netbook interface.

  • List item stuck in "Pending"

    - by Norgean
    Problem simplified: On approval, you have an event receiver that changes a field according to some weird and wonderful business logic. But the item remains in "Pending" state. Why?   First, you obviously need to turn off the event handling when you change things in the event receiver. If not, the event receiver will be called because the item changed. Infinite recursion is a bad thing. But you guessed that.   But that's not what was wrong. The culprit in my case was that items are set to require a new approval whenever the item is changed. This is good, but not what we want in this particular case. So force it back to approved after the other column has been changed.

  • Is there an OSS license that works for this:

    - by mattcodes
    Say you started as SaaS service with freemium business model such 37Signals - Basecamp or Dropbox etc.. Is there an OSS license that says that you can use the source code etc.. but you cant release a SaaS based on it, esssentially released in good faith with non-compete expectations. e.g. if 37Signals released the source for highrise, basecamp etc.. someone could start 37signals4lesss.com (albeit once they built the same bit of provisioning logic) and damage the core business model.

  • How to prioritize tasks when you have multiple programming projects running in parallel?

    - by Vinko Vrsalovic
    Say you have 5 customers, you develop 2 or 3 different projects for each. Each project has Xi tasks. Each project takes from 2 to 10 man weeks. Given that there are few resources, it is desired to minimize the management overhead. Two questions in this scenario: What tools would you use to prioritize the tasks and track their completion, while tending to minimize the overhead? What criteria would you take into consideration to determine which task to assign to the next available resource given that the primary objective is to increase throughput (more projects finished per time unit, this objective conflicts with starting one project and finishing it and then moving on to the next)? Ideas, management techniques, algorithms are welcome

  • Playing a sound on collision?

    - by Eric McLoughlin
    I'm making a pool game. I've separated the gameplay logic and the physics into two systems, entities and physics. Each entity holds a reference to a body which the physics system uses. The body itself holds a reference back to it's owner. When an entity collides with another entity, the Collided(Entity other) method is called on both. What I'm trying to do now is to play a sound when both entities colliding are of a certain subclass. I'm not sure how to do that. I could do it in the Collided method, but then the sound would be played two times at the same time, since the method was called on both entities. How do you suggest I do this?

  • How to solve this problem without the use of if-else statements?

    - by kira
    I have just started my C++ lecture class. And the teacher has given us the following assignment. Write a program that determines whether a number is even or odd. The logic I would use for the program is. Get input a. Store a % 2 as b. If b is 0, then b is even, else b is odd. The catch though, is that we have to write the program without the use of a if-else statement. I have been thinking on how to approach the problem for the past few hours, but I have no clue what to do. Any hints or suggestions?

  • Circular movement - eliminating speed ups near Y = 0

    - by Fibericon
    I have a basic algorithm to rotate an enemy around a 200 unit radius circle with center 0. This is how I'm achieving that: if (position.Y <= 0 && position.X > -200) { position.X -= 2; position.Y = 0 - (float)Math.Sqrt((200 * 200) - (position.X * position.X)); } else { position.X += 2; position.Y = (float)Math.Sqrt((200 * 200) - (position.X * position.X)); } It does work, and I've ensured that at no point does either X or Y equal NaN. However, when Y approaches 0, it seems to go significantly faster. This surprises me, because the Y values are locked to the X, which is being incremented by a steady amount. What can I do to smooth the speed?

  • Building an instance system.

    - by Kyle C
    I am looking into how to design an instance system for the game I am working on. I have always wondered how these are created in games like World of Warcraft, where instances == dungeons/raids/etc). Areas that are separated from players other than those in your group, but have specific logic to them. Specifically how can you reuse your existing code base and not have a bunch of checks everywhere ? if (isInstance) do x; else do y; I don't know if this will make too much of a difference on any answers, but we're using a pretty classic "Object as pure aggregation" component system for our entities.

  • How do you know when to split an object method into 2 or more other methods?

    - by blacktie24
    Hi, I know this is a very basic question, but I sometimes find myself struggling to figure out when to split a single object method into multiple methods. For example, I am trying to set up an ACL using Zend_Acl and Zend_Auth, as shown in this tutorial: http://devzone.zend.com/article/1665. However, I am wondering if the My_Plugin_Auth::preDispatch() method should invoke calls to a method called authenticate() and a method called authorize(), instead of having everything lumped in under preDispatch(). I was thinking that this would make the code more readable and encapsulate the logic into its smaller parts, but i'm not sure if this is reason enough.

  • Getting collision detection in Pygames

    - by user36010
    I am writing a game in Pygame, I want to get collision detection. The aim is when a object hits another, the target object disappears. I want to avoid having classes and just have my code class less for now, in one script. This makes it difficult to get collision detection because the Rect method in Pygame is called on by an object(class). The logic I want to achieve is: object hits a target object target object disappears. is there an easy way to achieve this?(with minimal code possible)

  • Algorithm for optimal combination of two variables

    - by AlanChavez
    I'm looking for an algorithm that would be able to determine the optimal combination of two variables, but I'm not sure where to start looking. For example, if I have 10,000 rows in a database and each row contains price, and square feet is there any algorithm out there that will be able to determine what combination of price and sq ft is optimal. I know this is vague, but I assume is along the lines of Fuzzy logic and fuzzy sets, but I'm not sure and I'd like to start digging in the right field to see if I can come up with something that solves my problem.

  • Why does the use of interface-based programming appear to be limited to behaviour?

    - by Carnotaurus
    I have been doing a little thinking about inheritance vs. realization vs. composition. I am not about to post the whole detail here. So I was wondering, when are not talking about supporting unit testing: Why does interface-based programming seem to focus upon the grouping of common behaviour, e.g., IPettable (for an animal), IEditable (for a user control), ISubmitable (for a form), etc. Why does the use of interface-based programming appear to be limited to behaviour when we could pragmatically group not so much on behaviour but on commonsense physical similarities which could have nothing to do with behaviour? It is not that there is some limiting feature within OOP; so how come?

  • Using mocks to set up object even if you will not be mocking any behavior or verifying any interaction with it?

    - by smp7d
    When building a unit test, is it appropriate to use a mocking tool to assist you in setting up an object even if you will not be mocking any behavior or verifying any interaction with that object? Here is a simple example in pseudo-code: //an object we actually want to mock Object someMockedObject = Mock(Object.class); EqualityChecker checker = new EqualityChecker(someMockedObject); //an object we are mocking only to avoid figuring out how to instantiate or //tying ourselves to some constructor that may be removed in the future ComplicatedObject someObjectThatIsHardToInstantiate = Mock(ComplicatedObject.class); //set the expectation on the mock When(someMockedObject).equals(someObjectThatIsHardToInstantiate).return(false); Assert(equalityChecker.check(someObjectThatIsHardToInstantiate)).isFalse(); //verify that the mock was interacted with properly Verify(someMockedObject).equals(someObjectThatIsHardToInstantiate).oneTime(); Is it appropriate to mock ComplicatedObject in this scenario?
