  • What is the difference between Times and Dup in Assembly Language?

    - by Total Anime Immersion
    In a bootloader, the second last line is : TIMES 510-($-$$) db 0 Now, will this command also do the same : db 510-($-$$) DUP (0) If not why? I know what TIMES does, but its not mentioned in my x86 book by Mazidi (Pearson Publication). Any idea why? And what is the meaning of the $ sign exactly? Different sites have different information about $. And is the line TIMES 510-($-$$) db 0 absolutely necessary even if my bootloader code is of 512 bytes in size? So can anyone help me with these questions?

  • Actionscript - Dropping Multiple Objects Using an Array?

    - by Eratosthenes
    I'm trying to get these fireBalls to drop more often, im not sure if im using Math.random correctly also, for some reason I'm getting a null reference because I think the fireBalls array waits for one to leave the stage before dropping another one? this is the relevant code: var sun:Sun=new Sun var fireBalls:Array=new Array() var left:Boolean; function onEnterFrame(event:Event){ if (left) { sun.x = sun.x - 15; }else{ sun.x = sun.x + 15; } if (fireBalls.length>0&&fireBalls[0].y>stage.stageHeight){ // Fireballs exit stage removeChild(fireBalls[0]); fireBalls.shift(); } for (var j:int=0; j<fireBalls.length; j++){ fireBalls[j].y=fireBalls[j].y+15; if (fireBalls[j].y>stage.stageHeight-fireBall.width/2){ } } if (Math.random()<.2){ // Fireballs shooting from Sun var fireBall:FireBall=new FireBall; fireBall.x=sun.x; addChild(fireBall); fireBalls.push(fireBall); } }

  • Is HTML5 more secure to develop for than Silverlight?

    - by King Chan
    I'm learning Silverlight, and I know that if I master it, I can apply the same concepts to WPF, which means I can do either web or desktop development pretty easily. But I've read articles and followed the discussion online, and I understand HTML5 is gaining traction for being cross-platform, and a lot of people seem to be moving to HTML5. From my understanding, any HTML5 application would be built with HTML and JavaScript (or Flash). But is it secure? It seems like anyone can easily use their browser's "view source" option and grab your code. Is this something I should be worried about, or is there a way to protect against it?

  • Print to file in Black and White [not printer specific]

    - by user2413
    Hi all, I have these pdf files of c++code and they are colored which would be cool, except that the network printer here is b&w and the printed out codes come in various shades of pale grey which makes them essentially unreadable (specially the comments). I would like everything (text, codes, commands,...) to be printed in the same (black) color. i've tried fuddling with the printer's properties, but the closest thing i see is the 'level of grey' tab, and there i have the choice between 'enhanced' and 'normal' (and it doesn't make a difference in my case). i've tried 'print to file', but i don't see any options there to print to b&w, I've tried installing the 'generic cups printer', but again no options to print to b&w. any idea ? (i'm on 10.10)

  • How to flag a class as under development in Java

    - by Usavich
    I'm working on a internship project, but I have to leave before I can finish up everything. I have 1 class that is not stable enough for production use. I want to mark/flag this class so that other people will not accidentally use it in production. I have already put the notice in Javadoc, but that doesn't seem enough. Some compiler error or warning would be better. The code is organized like this: [Package] | company.foo.bar.myproject |-- Class1.java |-- Class2.java |-- Class3.java <--(not stable) If there was a single factory class that calls those classes in public methods, I could have set the method to class3 as private. However the API is NOT exposed that way. Users will directly use those class, e.g. new Class1();, but I can't make a top-level class private. What's the best practice to deal with this situation?

  • What are startups expecting when they ask you to solve a programming challenge before interviewing? [closed]

    - by Swapnil Tailor
    I have applied to couple of startups and most of them are asking to solve programming challenge before they start on the interviewing candidate. I have submitted couple of the solutions and all the time getting rejected in the initial screening. Now what I think is, they will see my coding style, algorithm and OOD concepts that I have used to solve the problem. Can you guys input more on it as what other details are taken into consideration and how can I improve my coding for getting selected. By the way, I did all my coding in either Java/Perl. EDIT I feel the biggest reason for rejection is code didn't work for couple of use cases.

  • How can I rewrite a subdomain to go to a specific file in a specific folder?

    - by FasterHorses
    I've done searching for my answer and have tested a few solutions, but nothing has worked so far. I'm trying to get a URL like this: http://baseball.sports.com to rewrite to... http://pro.sports.com/baseball-index.php However, I still need to keep the domain the same (http://baseball.sports.com). The reason being I have about 5 subdomains (baseball, football, soccer, etc) that I want to run off the same code base (pro.sports.com). Everything is on the same server. I'd be happy to answer any other questions that would help me get a resolution. I truly appreciate any direction that can be given to me to solve this. Thanks! --Nick

  • Issues With IIS Hosting Two Domains From Same Folder [closed]

    - by Bob Mc
    I have two different domain names that resolve to the same ASP.Net site. Both domains are hosted on the same server, which runs Windows Server 2003 and IIS6. The sites are differentiated in IIS Manager using host headers. However, both of the sites point to the same folder on the local drive for the site's page files. I am occasionally experiencing an ASP.Net error that says "The state information is invalid for this page and might be corrupted." I'm the site developer so I've addressed all the relevant code-related causes for this issue. However, I was wondering whether having two domains/sites sharing the same folder for an ASP.Net application might be causing this intermittent error. Also, is this generally a bad practice? Should I make separate, duplicate folders for each of the domains? Seems like that can become a maintenance headache.

  • How can I improve the workflow between developer and designer with Expression Blend?

    - by Amenti
    We use WPF and Expression Blend 4. I'm trying to improve our workflow by tutoring one of our designers to use it for styling and animation. Slowly but surely I get the impression Blend in itself is to technical for the designer in question. I myself use it only occasionally (it's great for Visual States for instance) because a lot of things are easier done in code or not possible at all in Blend alone. It seems a developer with design experience is a lot more productive with it than a sole designer. Are there any good resources or advice as to how I can improve this workflow?

  • Getting Started with ADF Mobile Sample Apps

    - by Denis T
    Getting Started with ADF Mobile Sample Apps   Installation Steps Install JDeveloper 11.1.2.3.0 from Oracle Technology Network After installing JDeveloper, go to Help menu and select "Check For Updates" and find the ADF Mobile extension and install this. It will require you restart JDeveloper For iOS development, be on a Mac and have Xcode installed. (Currently only Xcode 4.4 is officially supported. Xcode 4.5 support is coming soon) For Android development, have the Android SDK installed. In the JDeveloper Tools menu, select "Preferences". In the Preferences dialog, select ADF Mobile. You can expand it to select configure your Platform preferences for things like the location of Xcode and the Android SDK. In your /jdeveloper/jdev/extensions/oracle.adf.mobile/Samples folder you will find a PublicSamples.zip. Unzip this into the Samples folder so you have all the projects ready to go. Open each of the sample application's .JWS file to open the corresponding workspace. Then from the "Application" menu, select "Deploy" and then select the deployment profile for the platform you wish to deploy to. Try deploying to the simulator/emulator on each platform first because it won't require signing. Note: If you wish to deploy to the Android emulator, it must be running before you start the deployment.   Sample Application Details   Recommended Order of Use Application Name Description 1 HelloWorld The "hello world" application for ADF Mobile, which demonstrates the basic structure of the framework. This basic application has a single application feature that is implemented with a local HTML file. Use this application to ascertain that the development environment is set up correctly to compile and deploy an application. See also Section 4.2.2, "What Happens When You Create an ADF Mobile Application." 2 CompGallery This application is meant to be a runtime application and not necessarily to review the code, though that is available. It serves as an introduction to the ADF Mobile AMX UI components by demonstrating all of these components. Using this application, you can change the attributes of these components at runtime and see the effects of those changes in real time without recompiling and redeploying the application after each change. See generally Chapter 8, "Creating ADF Mobile AMX User Interface." 3 LayoutDemo This application demonstrates the user interface layout and shows how to create the various list and button styles that are commonly used in mobile applications. It also demonstrates how to create the action sheet style of a popup component and how to use various chart and gauge components. See Section 8.3, "Creating and Using UI Components" and Section 8.5, "Providing Data Visualization." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 4 JavaDemo This application demonstrates how to bind the user interface to Java beans. It also demonstrates how to invoke EL bindings from the Java layer using the supplied utility classes. See also Section 8.10, "Using Event Listeners" and Section 9.2, "Understanding EL Support." 5 Navigation This application demonstrates the various navigation techniques in ADF Mobile, including bounded task flows and routers. It also demonstrates the various page transitions. See also Section 7.2, "Creating Task Flows." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 6 LifecycleEvents This application implements lifecycle event handlers on the ADF Mobile application itself and its embedded application features. This application shows you where to insert code to enable the applications to perform their own logic at certain points in the lifecycle. See also Section 5.6, "About Lifecycle Event Listeners." Note: iOS, the LifecycleEvents sample application logs data to the Console application, located at Applications-Utilities-Console application. 7 DeviceDemo This application shows you how to use the DeviceFeatures data control to expose such device features as geolocation, e-mail, SMS, and contacts, as well as how to query the device for its properties. See also Section 9.5, "Using the DeviceFeatures Data Control." Note: You must also run this application on an actual device because SMS and some of the device properties do not function on an iOS simulator or Android emulator. 8 GestureDemo This application demonstrates how gestures can be implemented and used in ADF Mobile applications. See also Section 8.4, "Enabling Gestures." 9 StockTracker This application demonstrates how data change events use Java to enable data changes to be reflected in the user interface. It also has a variety of layout use cases, gestures and basic mobile patterns. See also Section 9.7, "Data Change Events."

  • Developing GLSL Shaders?

    - by skln
    I want to create shaders but I need a tool to create and see the visual result before I put them into my game. As to determine if there is something wrong with my game or if it's something with the shader I created. I've looked at some like Render Monkey and OpenGL Shader Designer from what I recall of Render Monkey it had a way to define your own attributes (now as "in" for vertex shaders = 330) easily though I can't remember to what extent. Shader Designer requires a plugin that I didn't even bother to look at creating cause it's an external process and plugin. Are there any tools out there that support a scripting language and I could easily provide specific input such as float movement = sin(elapsedTime()); and then define in float movement; in the vertex shader ? It'd be cool if anyone could share how they develop shaders, if they just code away and then plug it into their game hoping to get the result they wanted.

  • how to bind super+s to indicator applete complete? - gnome classic

    - by rrosa
    i use gnome classic, i'm not a mouse fan. when i get an email while i'm writing code, i i would super+s to get to the indicator-applet-complete and read it. also to write emails, or check unread instant messages. upgrading from 12.04 to 14.04 made super+s bind to applications menu rather than the indicator applet complete. i removed the binding from the applications using dconf-editor, navigating to: org-gnome-desktop-wm-keybindings and disabling (['disabled']) the panel-main-menu key. now, how do i bind super+s to the indicator applet complete? it seems to be some how binded, since if if press super+s and then move the cursor over the applet it'll open the drop down menus (and it won't if i hover without pressing super+s) but i don't want to have to use the mouse...

  • Tunnels in pseudo 3D racing game

    - by Nicholas
    How would one go about doing tunnels in a pseudo 3D racing game ? The main problem I have at the moment is perspective - I cant think of a way, beyond having to Z sort the sprites and tunnel coordinates, so that vehicles are displayed in front of the tunnel entrance and somehow block the display when out of site. I would like my tunnels to be used on both flat, curved and hills and slopes. The tunnel enterance/exit is made up of 3 separate graphics, (left, right and top), whilst inside the tunnel it is just one line graphic along the top (the idea being its supposed to be a set distance above the current vertical road position). As you can see from the picture, the vehicles are still being rendered whilst in the tunnel. I've converted the Code Incomplete road system to GLBasic.

  • How do I tell my boss he made the wrong choice? [migrated]

    - by SomeKittens
    Recently, our biggest product failed majorly because we'd only used outsourced labor to do it, and they never tested anything, etc. Finally, our CEO decided that the US team should learn the code and fix it up. (Not a total rewrite, but lots of formatting/style changes, refactoring, etc). However, he knows next to nothing about programming (thankfully, he admits it). He had been grooming me to take on the project manager position, but I had to go back to college. Now he gave it to another programmer who is naive and inexperienced. I don't feel the naive programmer will do nearly as well. The CEO's reasoning is that the naive programmer can work full time and I can only do part time, so the less senior programmer could put more work into it. How can I convince him that 15 hours of my time is worth more than the other guy's 40?

  • VirtualBox: Start Firefox in Ubuntu via a Windows script?

    - by SpaceRook
    I am using VirtualBox to run Ubuntu 12.04 as a guest in a Windows 7 host. I would like execute a command in Windows that will launch Ubuntu's Firefox. I tried VirtualBox's VBoxManage guestcontrol function. The command seems to do something, but nothing seems to happen in Ubuntu: C:\VirtualBox>VBoxManage.exe guestcontrol MyVirtualMachineUbuntu exec --image "/usr/bin/firefox" --username bob --password password --wait-stdout --verbose Waiting for guest to start process ... Waiting for process to exit ... Exit code=1 (Status=500 [successfully terminated]) The /usr/bin/firefox command works when I run it in Ubuntu. Also, with guestcontrol, I can successfully call /bin/ls. But I can't actually get a major program like Firefox to run. Any ideas? Thanks.

    When I'm using C# to write some code and I define an interface using Visual Studio 2010, it always includes a number of "using" statements (as shown in the example) using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace TestEngine.TestNameSpace { interface ITest1 { bool testMethod(int xyz); } } I wonder what these are for and if they are really necessary. Can I leave these out? Are they only necessary when I'm using those parts in my interface description?
