• Watch the Geminid Meteors Tonight

  - by Jason Fitzpatrick

  Tonight is the peak of the Geminid Meteor shower, if you don’t mind braving the cold and have a spot relatively free from light pollution to stretch out in you’ll be able to enjoy one of the more brilliant and busy meteor showers of the year. Sky and Telescope magazine reports on the Geminid Meteor shower: If it’s clear late Thursday night, December 13th, 2012, keep a lookout high overhead for the shooting stars of the Geminid meteor shower. The Geminids are usually one of the two best meteor showers of the year, often beating out the Perseids of August. And this year there’s no moonlight to interfere. Under a clear, dark sky, you may see at least one Geminid per minute on average from roughly 10 p.m. Thursday until dawn Friday morning. If you live under the artificial skyglow of light pollution your numbers will be less, but the brightest meteors will still shine through. Hit up the link below to read the full article and learn more about the Geminid Meteor shower.

• Should I pick up a functional programming language?

  - by Statement

  I have recently been more concerned about the way I write my code. After reading a few books on design patterns (and overzealous implementation of them, I'm sure) I have shifted my thinking greatly toward encapsulating that which change. I tend to notice that I write less interfaces and more method-oriented code, where I love to spruce life into old classes with predicates, actions and other delegate tasks. I tend to think that it's often the actions that change, so I encapsulate those. I even often, although not always, break down interfaces to a single method, and then I prefer to use a delegate for the task instead of forcing client code to create a new class. So I guess it then hit me. Should I be doing functional programming instead? Edit: I may have a misconception about functional programming. Currently my language of choice is C#, and I come from a C++ background. I work as a game developer but I am currently unemployed. I have a great passion for architecture. My virtues are clean, flexible, reusable and maintainable code. I don't know if I have been poisoned by these ways or if it is for the better. Am I having a refactoring fever or should I move on? I understand this might be a question about "use the right tool for the job", but I'd like to hear your thoughts. Should I pick up a functional language? One of my fear factors is to leave the comfort of Visual Studio.

• New way of integrating Openfeint in Cocos2d-x 0.12.0

  - by Ef Es

  I am trying to implement OpenFeint for Android in my cocos2d-x project. My approach so far has been creating a button that calls a static java method in class Bridge using jnihelper functions (jnihelper only accepts statics). Bridge has one singleton attribute of type OFAndroid, that is the class dynamically calling the Openfeint Api methods, and every method in the bridge just forwards it to the OFAndroid object. What I am trying to do now is to initialize the openfeint libraries in the main java class that is the one calling the static C++ libraries. My problem right now is that the initializing function void com.openfeint.api.OpenFeint.initialize(Context ctx, OpenFeintSettings settings, OpenFeintDelegate delegate) is not accepting the context parameter that I am giving him, which is a "this" reference to the main class. Main class extends from Cocos2dxActivity but I don't have any other that extends from Application. Any suggestions on fixing it or how to improve the architecture? EDIT: I am trying a new solution. Make the bridge class into an Application child, is called from Main object, initializes OpenFeint when created and it can call the OpenFeint functions instead of needing an additional class. The problem is I still get the error. 03-30 14:39:22.661: E/AndroidRuntime(9029): Caused by: java.lang.NullPointerException 03-30 14:39:22.661: E/AndroidRuntime(9029): at android.content.ContextWrapper.getPackageManager(ContextWrapper.java:85) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.internal.OpenFeintInternal.validateManifest(OpenFeintInternal.java:885) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.internal.OpenFeintInternal.initializeWithoutLoggingIn(OpenFeintInternal.java:829) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.internal.OpenFeintInternal.initialize(OpenFeintInternal.java:852) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.api.OpenFeint.initialize(OpenFeint.java:47) 03-30 14:39:22.661: E/AndroidRuntime(9029): at nurogames.fastfish.NuroFeint.onCreate(NuroFeint.java:23) 03-30 14:39:22.661: E/AndroidRuntime(9029): at nurogames.fastfish.FastFish.onCreate(FastFish.java:47) 03-30 14:39:22.661: E/AndroidRuntime(9029): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1069) 03-30 14:39:22.661: E/AndroidRuntime(9029): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2751)

• What's the best algorithm for... [closed]

  - by Paska

  Hi programmers! Today come out a little problem. I have an array of coordinates (latitude and longitude) maded in this way: [0] = "45.01234,9.12345" [1] = "46.11111,9.12345" [2] = "47.22222,9.98765" [...] etc In a loop, convert these coordinates in meters (UTM northing / UTM easting) and after that i convert these coords in pixel (X / Y) on screen (the output device is an iphone) to draw a route line on a custom map. [0] = "512335.00000,502333.666666" [...] etc The returning pixel are passed to a method that draw a line on screen (simulating a route calculation). [0] = "20,30" [1] = "21,31" [2] = "25,40" [...] etc As coordinate (lat/lon) are too many, i need to truncate lat/lon array eliminating the values that doesn't fill in the map bound (the visible part of map on screen). Map bounds are 2 couple of coords lat/lon, upper left and lower right. Now, what is the best way to loop on this array (NOT SORTED) and check if a value is or not in bound and after remove the value that is outside? To return a clean array that contains only the coords visible on screen? Note: the coords array is a very big array. 4000/5000 couple of items. This is a method that should be looped every drag or zoom. Anyone have an idea to optimize search and controls in this array? many thanks, A

• MVC Validation with ModelState.isValid through a wizard

  - by Emmanuel TOPE

  I'm working on a small educational project on MVC 3, and I'm facing a small problem, when attempting to handle validation in my application through a wizard. I tried to get benefit from the ability of MVC3 to deliver content of a different view using the same URL, when handling an [HttpPost] method on a page. I my case,my main model's class contains about ten [Required] properties, that I would like to expose through a small wizard in 3 steps , So I want that the user may be able to enter his personal informations in the first step, then respond to some questions in the second stepp and finally receive a confirmation mail from the web application whit his credentials in the last step. I can't access the last step, because of the ModelState.isValid method that I use to handle validations, and which can't perform properly if I define some properties as [Required], but don't put them on the first view. As the replies to those questions remain in a couple of choices, I've thinked that I may use some nullable bool? for in order to avoid validation issues, but know that it's not the proper way. Are there someone who would like to help me find a way to extend my validation to those three steps ? Thanks in advance and sorry for my english, I'm not a native speaker.

• How to get initial API right using TDD?

  - by Vytautas Mackonis

  This might be a rather silly question as I am at my first attempts at TDD. I loved the sense of confidence it brings and generally better structure of my code but when I started to apply it on something bigger than one-class toy examples, I ran into difficulties. Suppose, you are writing a library of sorts. You know what it has to do, you know a general way of how it is supposed to be implemented (architecture wise), but you keep "discovering" that you need to make changes to your public API as you code. Perhaps you need to transform this private method into strategy pattern (and now need to pass a mocked strategy in your tests), perhaps you misplaced a responsibility here and there and split an existing class. When you are improving upon existing code, TDD seems a really good fit, but when you are writing everything from scratch, the API you write tests for is a bit "blurry" unless you do a big design up front. What do you do when you already have 30 tests on the method that had its signature (and for that part, behavior) changed? That is a lot of tests to change once they add up.

• Oracle Supply Chain at Pella Showcase, April 24-25, 2012

  - by Stephen Slade

  Nothing promtes a product like a grest customer testimony! For nearly a decade, Pella has been holding these 'open-houses' or Showcases as they are called, to illustrate the utilization of Oracle products in their operations. Building custom windows and doors is not an easy task.  With about a trillion combinations of unique sizes, colors and features availalbe, getting the complex multi-unit custom order wrong can be easy to do. I've been to a few of these Showcases and each time,  continually impressed by the precision, best practices and lean disciplines enacted at Pella. Operations representatives and users at Pella, demonstrate the way in which they use Oracle Supply Chain products to deliver fulfillment excellence. Orders are all custom made and delivered in about a week.  Factory tours are conducted and visitors have a chance to see Oracle in operation on the shop floor, driving informational flow and order accuracy in the 99+% range.  It's a must see for anyone considering expansion of their supply chain footprint.  The event is April 24-25 in Pella Iowa, outside Des Moines.   This year, there is a seperate track for CIOs and executives.

• Dependency injection: what belongs in the constructor?

  - by Adam Backstrom

  I'm evaluating my current PHP practices in an effort to write more testable code. Generally speaking, I'm fishing for opinions on what types of actions belong in the constructor. Should I limit things to dependency injection? If I do have some data to populate, should that happen via a factory rather than as constructor arguments? (Here, I'm thinking about my User class that takes a user ID and populates user data from the database during construction, which obviously needs to change in some way.) I've heard it said that "initialization" methods are bad, but I'm sure that depends on what exactly is being done during initialization. At the risk of getting too specific, I'll also piggyback a more detailed example onto my question. For a previous project, I built a FormField class (which handled field value setting, validation, and output as HTML) and a Model class to contain these fields and do a bit of magic to ease working with fields. FormField had some prebuilt subclasses, e.g. FormText (<input type="text">) and FormSelect (<select>). Model would be subclassed so that a specific implementation (say, a Widget) had its own fields, such as a name and date of manufacture: class Widget extends Model { public function __construct( $data = null ) { $this->name = new FormField('length=20&label=Name:'); $this->manufactured = new FormDate; parent::__construct( $data ); // set above fields using incoming array } } Now, this does violate some rules that I have read, such as "avoid new in the constructor," but to my eyes this does not seem untestable. These are properties of the object, not some black box data generator reading from an external source. Unit tests would progressively build up to any test of Widget-specific functionality, so I could be confident that the underlying FormFields were working correctly during the Widget test. In theory I could provide the Model with a FieldFactory() which could supply custom field objects, but I don't believe I would gain anything from this approach. Is this a poor assumption?

• Which approach would lead to an API that is easier to use?

  - by Clem

  I'm writing a JavaScript API and for a particular case, I'm wondering which approach is the sexiest. Let's take an example: writing a VideoPlayer, I add a getCurrentTime method which gives the elapsed time since the start. The first approach simply declares getCurrentTime as follows: getCurrentTime():number where number is the native number type. This approach includes a CURRENT_TIME_CHANGED event so that API users can add callbacks to be aware of time changes. Listening to this event would look like the following: myVideoPlayer.addEventListener(CURRENT_TIME_CHANGED, function(evt){ console.log ("current time = "+evt.getDispatcher().getCurrentTime()); }); The second approach declares getCurrentTime differently: getCurrentTime():CustomNumber where CustomNumber is a custom number object, not the native one. This custom object dispatches a VALUE_CHANGED event when its value changes, so there is no need for the CURRENT_TIME_CHANGED event! Just listen to the returned object for value changes! Listening to this event would look like the following: myVideoPlayer.getCurrentTime().addEventListener(VALUE_CHANGED, function(evt){ console.log ("current time = "+evt.getDispatcher().valueOf()); }); Note that CustomNumber has a valueOf method which returns a native number that lets the returned CustomNumber object being used as a number, so: var result = myVideoPlayer.getCurrentTime()+5; will work! So in the first approach, we listen to an object for a change in its property's value. In the second one we directly listen to the property for a change on its value. There are multiple pros and cons for each approach, I just want to know which one the developers would prefer to use!

• How to design a scriptable communication emulator?

  - by Hawk

  Requirement: We need a tool that simulates a hardware device that communicates via RS232 or TCP/IP to allow us to test our main application which will communicate with the device. Current flow: User loads script Parse script into commands User runs script Execute commands Script / commands (simplified for discussion): Connect RS232 = RS232ConnectCommand Connect TCP/IP = TcpIpConnectCommand Send data = SendCommand Receive data = ReceiveCommand Disconnect = DisconnectCommand All commands implement the ICommand interface. The command runner simply executes a sequence of ICommand implementations sequentially thus ICommand must have an Execute exposure, pseudo code: void Execute(ICommunicator context) The Execute method takes a context argument which allows the command implementations to execute what they need to do. For instance SendCommand will call context.Send, etc. The problem RS232ConnectCommand and TcpIpConnectCommand needs to instantiate the context to be used by subsequent commands. How do you handle this elegantly? Solution 1: Change ICommand Execute method to: ICommunicator Execute(ICommunicator context) While it will work it seems like a code smell. All commands now need to return the context which for all commands except the connection ones will be the same context that is passed in. Solution 2: Create an ICommunicatorWrapper (ICommunicationBroker?) which follows the decorator pattern and decorates ICommunicator. It introduces a new exposure: void SetCommunicator(ICommunicator communicator) And ICommand is changed to use the wrapper: void Execute(ICommunicationWrapper context) Seems like a cleaner solution. Question Is this a good design? Am I on the right track?

• PostgreSQL, Ubuntu, NetBeans IDE (Part 3)

  - by Geertjan

  To complete the picture, let's use the traditional (that is, old) Hibernate mechanism, i.e., via XML files, rather than via the annotations shown yesterday. It's definitely trickier, with many more places where typos can occur, but that's why it's the old mechanism. I do not recommend this approach. I recommend the approach shown yesterday. The other players in this scenario include PostgreSQL, as outlined in the previous blog entries in this series. Here's the structure of the module, replacing the code shown yesterday: Here's the Employee class, notice that it has no annotations: import java.io.Serializable; import java.util.Date; public class Employees implements Serializable {         private int employeeId;     private String firstName;     private String lastName;     private Date dateOfBirth;     private String phoneNumber;     private String junk;     public int getEmployeeId() {         return employeeId;     }     public void setEmployeeId(int employeeId) {         this.employeeId = employeeId;     }     public String getFirstName() {         return firstName;     }     public void setFirstName(String firstName) {         this.firstName = firstName;

• How to reduce the fan noise and how to increase battery life?

  - by mehdi

  I have a brand new Sony Vaio S series laptop.(VPCSA2DGX) It came factory installed with Windows 7 professional Edition 64bit. Runs Intel core i5, 500 GB HDD , 4GB Ram. First I installed ubuntu 11.10 64 bit along side Windows to dual boot. Later,since the problem did not solve, I installed ubuntu 12.04 64bit along side Windows to dual boot. However the problem keeps annoying me. Problem: When running ubuntu 11.10/12.04, the battery lasts only about 1.5 hours. The Fan runs loud and continuously. And there is a lot of heat generated. System monitor shows less than 5% CPU used. My laptop enjoys hybrid graphic and I tried turning off ADM graphic card and keep Intel graphic card on. However I can not get the Fan noise or heat to go away and consequently the battery drain continues. BTW, in windows, the laptop gives 4-5 hours of battery power, Fan is silent and there is no heat problem. Any ideas on how to reduce the fan noise and how to increase battery life in ubuntu 11.10/12.04?

• Nexus 7 Possibly Bricked

  - by user214186

  I have a 1st gen Nexus 7 (32GB). I used the steps at https://wiki.ubuntu.com/Nexus7/Installation to successfully install Ubuntu 13.04 desktop onto the tablet. It was working fine and then I decided to upgrade to Ubuntu Touch. I booted the tablet into fast boot mode but the commands 'adb devices' and 'sudo fastboot devices' would not see the device. I am performing these steps from an Ubuntu 12.04 desktop PC. Prior to installing 13.04 the device was seen fine. I made the mistake of performing the 'Device factory reset' step from https://wiki.ubuntu.com/Touch/Install - Step 2. Now when I try to boot the device I get the following: mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /dev on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Targe filesystem doesn't have requested /sbin/init. No init found. Try passing init= bootarg. BusyBox v1.20.2 (Ubuntu 1:1.20.0-0ubuntu1) built-in shell (ash) Enter help for a list of built-in commands. (initramfs) I have searched the web but every reference to this problem is from people who still have ADB access to the device so they can recover by flashing the tablet again. I can attach a keyboard to the USB port and access the BusyBox console but I don't know what steps to do to recover from my error. Any suggestions would be helpful. Thanks

• how to make HLSL effect just for lighning without texture mapping?

  - by naprox

  I'm new to XNA, i created an effect and just want to use lightning but in default effect that XNA create we should do texture mapping or the model appears 'RED', because of this lines of code in the effect file: float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { float4 output = float4(1,0,0,1); return output; } and if i want to see my model (appear like when i use basiceffect) must do texture mapping by UV coordinates. but my model does not have UV coordinates assigned or its UV coordinates is not exported. and if i do texture mapping i got error. (i do texture mapping by this line of code in vertexshaderfunction and other necessary codes) output.UV= input.UV i have many of this models and want to work with them.(my models are in .FBX format) when i use Bassiceffect i have no problem and model appears correctly. how can i use "just" lightnings in my custom effects? and don't do texture mapping (because i have no UV coordinates in my models) and my model be look like when i use BasicEffect? if you need my complete code Here it is: http://www.mediafire.com/?4jexhd4ulm2icm2 here is inside of my Model Using BasicEffect http://i.imgur.com/ygP2h.jpg?1 and this is my code for drawing with or without BasicEffect inside of my draw() method: Matrix baseWorld = Matrix.CreateScale(Scale) * Matrix.CreateFromYawPitchRoll(Rotation.Y, Rotation.X, Rotation.Z) * Matrix.CreateTranslation(Position); foreach(ModelMesh mesh in Model.Meshes) { Matrix localWorld = ModelTransforms[mesh.ParentBone.Index] * baseWorld; foreach(ModelMeshPart part in mesh.MeshParts) { Effect effect = part.Effect; if (effect is BasicEffect) { ((BasicEffect)effect).World = localWorld; ((BasicEffect)effect).View = View; ((BasicEffect)effect).Projection = Projection; ((BasicEffect)effect).EnableDefaultLighting(); } else { setEffectParameter(effect, "World", localWorld); setEffectParameter(effect, "View", View); setEffectParameter(effect, "Projection", Projection); setEffectParameter(effect, "CameraPosition", CameraPosition); } } mesh.Draw(); } setEffectParameter is another method that sets effect parameter if i use my custom effect.

• Displaying Exceptions Thrown or Caught in Managed Beans

  - by Frank Nimphius

  Just came a cross a sample written by Steve Muench, which somewhere deep in its implementation details uses the following code to route exceptions to the ADF binding layer to be handled by the ADF model error handler (which can be customized by overriding the DCErrorHandlerImpl class and configuring the custom class in DataBindings.cpx file) To route an exception to the ADFm error handler, Steve used the following code ((DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry()).reportException(ex); The same code however can be used in managed beans as well to enforce consistent error handling in ADF. As an example, lets assume a managed bean method hits an exception. To simulate this, let's use the following code: public void onToolBarButtonAction(ActionEvent actionEvent) {    throw new JboException("Just to tease you !!!!!");        } The exception shows at runtime as displayed in the following image: Assuming a try-catch block is used to intercept the exception caused by a managed bean action, you can route the error message display to the ADF model error handler. Again, let's simulate the code that would need to go into a try-catch block public void onToolBarButtonAction(ActionEvent actionEvent) {    JboException ex = new JboException("Just to tease you !!!!!");  BindingContext bctx = BindingContext.getCurrent();    ((DCBindingContainer)bctx.getCurrentBindingsEntry()).reportException(ex); } The error now displays as shown in the image below As you can see, the error is now handled by the ADFm Error handler, which - as mentioned before - could be a custom error handler. Using the ADF model error handling for displaying exceptions thrown in managed beans require the current ADF Faces page to have an associated PageDef file (which is the case if the page or view contains ADF bound components). Note that to invoke methods exposed on the business service it is recommended to always work through the binding layer (method binding) so that in case of an error the ADF model error handler is automatically used.

• Question about separating game core engine from game graphics engine...

  - by Conrad Clark

  Suppose I have a SquareObject class, which implements IDrawable, an interface which contains the method void Draw(). I want to separate drawing logic itself from the game core engine. My main idea is to create a static class which is responsible to dispatch actions to the graphic engine. public static class DrawDispatcher<T> { private static Action<T> DrawAction = new Action<T>((ObjectToDraw)=>{}); public static void SetDrawAction(Action<T> action) { DrawAction = action; } public static void Dispatch(this T Obj) { DrawAction(Obj); } } public static class Extensions { public static void DispatchDraw<T>(this object Obj) { DrawDispatcher<T>.DispatchDraw((T)Obj); } } Then, on the core side: public class SquareObject: GameObject, IDrawable { #region Interface public void Draw() { this.DispatchDraw<SquareObject>(); } #endregion } And on the graphics side: public static class SquareRender{ //stuff here public static void Initialize(){ DrawDispatcher<SquareObject>.SetDrawAction((Square)=>{//my square rendering logic}); } } Do this "pattern" follow best practices? And a plus, I could easily change the render scheme of each object by changing the DispatchDraw parameter, as in: public class SuperSquareObject: GameObject, IDrawable { #region Interface public void Draw() { this.DispatchDraw<SquareObject>(); } #endregion } public class RedSquareObject: GameObject, IDrawable { #region Interface public void Draw() { this.DispatchDraw<RedSquareObject>(); } #endregion } RedSquareObject would have its own render method, but SuperSquareObject would render as a normal SquareObject I'm just asking because i do not want to reinvent the wheel, and there may be a design pattern similar (and better) to this that I may be not acknowledged of. Thanks in advance!

• Should a model binder populate all of the model?

  - by Richard

  Should a model binder populate all of the model, or only the bits that are being posted? For example, I am adding a product in my system and on the form i want the user to select which sites the new product will appear on. Therefore, in my model I want to populate a collection called "AllAvailableSites" to render the checkboxes for the user to choose from. I also need to populate the model with any chosen sites on a post in case the form does not validate, and I need to represent the form showing the initial selections. It would seem that I should let the model binder set the chosen sites on the model, and (once in the controller method) I set the "AllAvailableSites" on the model. Does that sound right? It seems more efficient to set everything in the model binder but someone is suggesting it is not quite right. I am grateful for any advice; I have to say that all the MVC model binding help online seems to cite really simple examples, nothing complicated. Do I really need a GET and a POST version of a method? Can't they just take the same view model? Then I check in my model binder if it is a GET/POST, and populate all the model accordingly.

• How does this ruby error handling module code work

  - by Michael Durrant

  Trying to get a better handle on ruby exception handling. I have this code (from a book): def err_with_msg(pattern) m = Module.new (class << m; self; end).instance_eval do define_method(:===) do |e| pattern === e.msg end end m end So ok this is a method. We're creating a new Module. I think of module as mix-ins. Not sure what it's doing here. Not we add the module to the class. Fair enough. Then we have self on its own. What that for? I guess we have a little anonymouse method this is just about self. hmmm ok, now for each of the above, check the pattern match. but for each, I thought the above for for a new Module, did the module get to use instance's by being included? A better explanation of what's going on here would be most helpful.

• The Differences between MAC Address and Network Layer Address

  A Mac address is a fixed number associated with a NICs onboard memory. It is initially assigned at the factory. The MAC address is broken up into 2 parts. The first part is the Block id which is six digit sequences that is unique to each vender. The second section is the device id which is created and assigned by the manufacture. A Network layer address is different because there format based on the type of protocol and network used. Also, there unique id is based on a hierarchal addressing theme on subsets of data  and narrowing it down. Just like in an address you can narrow down your house, for example: Florida, Boca Raton, 33428, SW 53th street states that you live in Florida. You also live in the area located in Florida called Boca Raton and you are also in the area of 33428 which is located in Boca Raton. Finally you live on SW 8th street which is in the area of 33428 which is located in Boca Raton which is also located in Florida.

• Converting raw data type to enumerated type

  - by Jim Lahman

  There are times when an enumerated type is preferred over using the raw data type.  An example of using a scheme is when we need to check the health of x-ray gauges in use on a production line.  Rather than using a scheme like 0, 1 and 2, we can use an enumerated type: 1: /// <summary> 2: /// POR Healthy status indicator 3: /// </summary> 4: /// <remarks>The healthy status is for each POR x-ray gauge; each has its own status.</remarks> 5: [Flags] 6: public enum POR_HEALTH : short 7: { 8: /// <summary> 9: /// POR1 healthy status indicator 10: /// </summary> 11: POR1 = 0, 12: /// <summary> 13: /// POR2 healthy status indicator 14: /// </summary> 15: POR2 = 1, 16: /// <summary> 17: /// Both POR1 and POR2 healthy status indicator 18: /// </summary> 19: BOTH = 2 20: } By using the [Flags] attribute, we are treating the enumerated type as a bit mask.  We can then use bitwise operations such as AND, OR, NOT etc. . Now, when we want to check the health of a specific gauge, we would rather use the name of the gauge than the numeric identity; it makes for better reading and programming practice. To translate the numeric identity to the enumerated value, we use the Parse method of Enum class: POR_HEALTH GaugeHealth = (POR_HEALTH) Enum.Parse(typeof(POR_HEALTH), XrayMsg.Gauge_ID.ToString()); The Parse method creates an instance of the enumerated type.  Now, we can use the name of the gauge rather than the numeric identity: 1: if (GaugeHealth == POR_HEALTH.POR1 || GaugeHealth == POR_HEALTH.BOTH) 2: { 3: XrayHealthyTag.Name = Properties.Settings.Default.POR1XRayHealthyTag; 4: } 5: else if (GaugeHealth == POR_HEALTH.POR2) 6: { 7: XrayHealthyTag.Name = Properties.Settings.Default.POR2XRayHealthyTag; 8: }

  i'm pretty new to Linux and my new problem is ATI drivers. When i installed Ubuntu then i had black screen issue with the blinking in left upper corner, fixed it with F6 and set the "nolapic" mode, can boot only with "nolapic". Now the problem is the drivers. The suggested drivers, from the "Additional drivers" are not working. Always freeze at the login screen, the divers are: ATI/AMD proprietary FGLRX graphics driver Tried this method: http://drivers.downloadatoz.com/tutorial/28786,how-to-fix-amd-catalyst-11-10-not-working-on-ubuntu-11-10-issues.html? but this method break it down really hard, not ever that helped anymore: sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists); sudo apt-get remove --purge fglrx*; sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon ; sudo apt-get install xserver-xorg-video-ati; sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core; sudo dpkg-reconfigure xserver-xorg Now i'm here with a fresh install and i cant find anything that works, can someone help me please! I like Ubuntu, but i need to get rid of the lagg, or its Windows 7 only for me then :( Thanks for reading!

• How do I draw a single Triangle with XNA and fill it with a Texture?

  - by Deukalion

  I'm trying to wrap my head around: http://msdn.microsoft.com/en-us/library/bb196409.aspx I'm trying to create a method in XNA that renders a single Triangle, then later make a method that takes a list of Triangles and renders them also. But it isn't working. I'm not understanding what all the things does and there's not enough information. My methods: // Triangle is a struct with A, B, C (didn't include) A, B, C = Vector3 public static void Render(GraphicsDevice device, List<Triangle> triangles, Texture2D texture) { foreach (Triangle triangle in triangles) { Render(device, triangle, texture); } } public static void Render(GraphicsDevice device, Triangle triangle, Texture2D texture) { BasicEffect _effect = new BasicEffect(device); _effect.Texture = texture; _effect.VertexColorEnabled = true; VertexPositionColor[] _vertices = new VertexPositionColor[3]; _vertices[0].Position = triangle.A; _vertices[1].Position = triangle.B; _vertices[2].Position = triangle.B; foreach (var pass in _effect.CurrentTechnique.Passes) { pass.Apply(); device.DrawUserIndexedPrimitives<VertexPositionColor> ( PrimitiveType.TriangleList, _vertices, 0, _vertices.Length, new int[] { 0, 1, 2 }, // example has something similiar, no idea what this is 0, 3 // 3 = gives me an error, 1 = works but no results ); } }
