• Flash intro or embedded video?

  - by Ray

  So a client of mine wants his homepage to start off something like this: http://www.roche-bobois.com/#/en-CA/home (It's basically a Flash intro that starts with a vector drawing of a furniture showroom that eventually transitions into the image of the actual showroom). Given that some of his users will be using an iPad to view his site, what are some of the alternatives that other developers here use? I'm thinking: Option 1: With PHP, detect if the user is using an iPad/iPhone by checking their user agent string. If they are using a mobile device, then forward to m.abccompany.com (mobile version of the site). Option 2: Convert the Flash video to MP4 or AVI and then embed that, which would allow all users to view his site. Any suggestions if either of these approaches are a good idea?

• Thunderbird/Firefox with shared profiles (Lubuntu+WinXP)

  - by Ray

  I use Thunderbird and Firefox both on WinXP and Lubuntu 11.10. The profile folders are on the NTFS-partition of Windows and I'm sure that I've edited the profile paths correctly. Windows doesn't show any problems but Lubuntu shows the error dialog saying that another instance of Thunderbird/Firefox is already running..." The funny thing is, that as soon as I've opened the profile folders in my explorer, firefox and thunderbird can be started. I don't have to change any files or something (Have made some experiments with .parentlock) Do you have an idea how I could solve this problem, as I don't want to open the profile folders after every reboot. Thanks in advance!

• In Search of Automatic ORM with REST interface

  - by Dan Ray

  I have this wish that so far Google hasn't been able to fulfill. I want to find a package (ideally in PHP, because I know PHP, but I guess that's not a hard requirement) that you point at a database, it builds an ORM based on what it finds there, and exposes a REST interface over the web. Everything I've found in my searches requires a bunch of code--like, it wants you to build the classes for it, but it'll handle the REST request routing. Or it does database and relational stuff just fine, but you have to build your own methods for all the CRUD actions. That's dumb. REST is well defined. If I wanted to re-invent the wheel, I totally could, but I don't want to. Isn't there somebody who's built a one-shot super-simple auto-RESTing web service package?

• Performance issues with visibility detection and object transparency

  - by maul

  I'm working on a 3d game that has a view similar to classic isometric games (diablo, etc.). One of the things I'm trying to implement is the effect of turning walls transparent when the player walks behind them. By itself this is not a huge issue, but I'm having trouble determining which walls should be transparent exactly. I can't use a circle or square mask. There are a lot of cases where the wall piece at the same (relative) position has different visibility depending on the surrounding area. With the help of a friend I came up with this algorithm: Create a grid around the player that contains a lot of "visibility points" (my game is semi tile-based so I create one point for every tile on the grid) - the size of the square's side is close to the radius where I make objects transparent. I found 6x6 to be a good value, so that's 36 visibility points total. For every visibility point on the grid, check if that point is in the player's line of sight. For every visibility point that is in the LOS, cast a ray from the camera to that point and mark all objects the ray hits as transparent. This algorithm works - not perfectly, but only requires some tuning - however this is very slow. As you can see, it requries 36 ray casts minimum, but most of the time 60-70 depending on the position. That's simply too much for the CPU. Is there a better way to do this? I'm using Unity 3D but I'm not looking for an engine-specific solution.

• Help to organize game cycle in Java

  - by ASIO22

  I'm pretty new here (as though to a game development). So here's my question. I'm trying to organize a really simple game cycle in my public static main() as follows: Scanner sc = new Scanner(System.in); //Running the game cycle boolean flag=true; while (flag) { int action; System.out.println("Type your action please:"); System.out.println("0: Exit app"); try { action = sc.nextInt(); switch (action) { case 0: flag=false; break; case 1: break; } } catch (InputMismatchException ex) { System.out.println(ex.getClass() + "\n" + "Please type a correct input\n"); //action = sc.nextInt(); continue; } What's wrong with this cycle: I want to catch an exception when user types text instead of number, show a message, warning user, and the continue game cycle, read user input etc. But instead of that, when users types wrong data, it goes into a eternal cycle without even prompting user. What I did wrong?

• Error trying to install the Java SDK

  - by Ray

  I need to install the Java 6 SDK, but after running this: sudo apt-get install sun-java6-jdk sun-java6-jre sun-java6-source I end up with this: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: sun-java6-jdk : Depends: sun-java6-bin (>= 6.26-1lucid1) but it is not going to be installed sun-java6-jre : Depends: sun-java6-bin (>= 6.26-1lucid1) but it is not going to be installed or ia32-sun-java6-bin (>= 6.26-1lucid1) but it is not installable Recommends: gsfonts-x11 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). I'm quite new to Ubuntu and need the packages for my course. I guess they've become corrupted but, how can I fix this?

• DIA2012

  - by Chris Kawalek

  If you've read this blog before, you probably know that Oracle desktop virtualization is used to demonstrate Oracle Applications at many different trade shows. This week, the Oracle desktop team is at DIA2012 in Philadelphia, PA. The DIA conference is a large event, hosting about 7,000 professionals in the pharmaceutical, bio technology, and medical device fields. Healthcare and associated fields are leveraging desktop virtualization because the model is a natural fit due to their high security requirements. Keeping all the data on the server and not distributing it on laptops or PCs that could be stolen makes a lot of sense when you're talking about patient records and other sensitive information. We're proud to be supporting the Oracle Health Sciences team at DIA2012 by hosting all of the Oracle healthcare related demos on a central server, and providing simple, smart card based access using our Sun Ray Clients. And remember that you're not limited to using just Sun Ray Clients--you can also use the Oracle Virtual Desktop Client and freely move your session from your iPad, your Windows or Linux PC, your Mac, or Sun Ray Clients. It's a truly mobile solution for an industry that requires mobile, secure access in order to remain compliant. Here are some pics from the show: We also have an informative PDF on Oracle desktop virtualization and Oracle healthcare that you can have a look at.  (Many thanks to Adam Workman for the pics!) -Chris  For more information, please go to the Oracle Virtualization web page, or  follow us at :  Twitter   Facebook YouTube Newsletter

• Remap keyboard Ubuntu 12.04; Asus Q500A

  - by hydroxide

  I have an Asus Q500A with win8 and Ubuntu 12.04 64 bit; linux kernel 3.8.0-32-generic. I am using gnome-panel, and xserver-xorg-lts-raring. I have been experiencing problems with the keyboard short-cuts since I had a fresh install. fn+f10 is supposed to mute my system, but instead it will repeatedly press d. fn+f11 is volume down, but it presses c. fn+f12 is volume up, presses b repeatedly. Most of the other on-board short-cuts such as adjusting screen and led brightness work most of the time, but sometimes press other letters repeatedly. Also, sometimes my cntr gets held down for no reason. Everything works fine in windows. I have tried installing all recommends and sudo dpkg-reconfigure -a to reconfigure all packages, which did not solve my problem. I have tried using KeyTouch editor to edit keymaps, navigating to /usr/shar/x11/xkb/keymap when I try opening any of these files it says file contains no keyboard element. I think If I were just able to remap my keyboard it might solve my issues, otherwise if anyone knows where I can get asus drivers for 12.04 please let me know Apparently I didn't have all repositories enabled. I executed the following commands and am trying the updates they give me. Getting linux_kernel 3.8.0-33 generic as well as a bunch of other packages. sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe" sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse" sudo add-apt-repository "deb http://archive.canonical.com/ubuntu $(lsb_release -sc) partner"

• Unity3D: How to make the camera focus a moving game object with ITween?

  - by nathan

  I'm trying to write a solar system with Unity3D. Planets are sphere game objects rotating around another sphere game object representing the star. What i want to achieve is let the user click on a planet and then zoom the camera on this planet and then make the camera follow and keep it centered on the screen while it keep moving around the star. I decided to use iTween library and so far i was able to create the zoom effect using iTween.MoveUpdate. My problem is that the focused planet does not say properly centered as it moves. Here is the relevant part of my script: void Update () { if (Input.GetButtonDown("Fire1")) { Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit; if (Physics.Raycast(ray, out hit, Mathf.Infinity, concernedLayers)) { selectedPlanet = hit.collider.gameObject; } } } void LateUpdate() { if (selectedPlanet != null) { Vector3 pos = selectedPlanet.transform.position; pos.z = selectedPlanet.transform.position.z - selectedPlanet.transform.localScale.z; pos.y = selectedPlanet.transform.position.y; iTween.MoveUpdate(Camera.main.gameObject, pos, 2); } } What do i need to add to this script to make the selected planet stay centered on the screen? I hosted my current project as a webplayer application so you see what's going wrong. You can access it here.

• Windows Server 2008R2 IIS7.5, Requests getting 401 status

  - by TLBH

  We have a web site running in windows server 2008r2 iis7.5 and we are seeing several errors reported from our global error handler saying that "Request Timed Out". I matched up one to the IIS log file and see the request took 135116 (presumably milliseconds) had an sc-status of 401 an sc-sub0status of 0 and an sc-win32-status of 64. 2 requests failed in these way but lots of surrounding requests (1979 successful requests vs 2 fails) for the same user went through perfectly fine- with the same cs-username which makes a 401 seem a little odd. The target of the requests is an ASP.Net web service's web method called by the .net client library- it's called a lot of times per user (3 times per second) to keep a page updated. We're getting some users reportng seeing a freezing effect and I think this may be the cause, any ideas? Peter

• Failed Project: When to call it?

  - by Dan Ray

  A few months ago my company found itself with its hands around a white-hot emergency of a project, and my entire team of six pulled basically a five week "crunch week". In the 48 hours before go-live, I worked 41 of them, two back to back all-nighters. Deep in the middle of that, I posted what has been my most successful question to date. During all that time there was never any talk of "failure". It was always "get it done, regardless of the pain." Now that the thing is over and we as an organization have had some time to sit back and take stock of what we learned, one question has occurred to me. I can't say I've ever taken part in a project that I'd say had "failed". Plenty that were late or over budget, some disastrously so, but I've always ended up delivering SOMETHING. Yet I hear about "failed IT projects" all the time. I'm wondering about people's experience with that. What were the parameters that defined "failure"? What was the context? In our case, we are a software shop with external clients. Does a project that's internal to a large corporation have more space to "fail"? When do you make that call? What happens when you do? I'm not at all convinced that doing what we did is a smart business move. It wasn't my call (I'm just a code monkey) but I'm wondering if it might have been better to cut our losses, say we're not delivering, and move on. I don't just say that due to the sting of the long hours--the company royally lost its shirt on the project, plus the intangible costs to the company in terms of employee morale and loyalty were large. Factor that against the PR hit of failing to deliver a high profile project like this one was... and I don't know what the right answer is.

• Uses of persistent data structures in non-functional languages

  - by Ray Toal

  Languages that are purely functional or near-purely functional benefit from persistent data structures because they are immutable and fit well with the stateless style of functional programming. But from time to time we see libraries of persistent data structures for (state-based, OOP) languages like Java. A claim often heard in favor of persistent data structures is that because they are immutable, they are thread-safe. However, the reason that persistent data structures are thread-safe is that if one thread were to "add" an element to a persistent collection, the operation returns a new collection like the original but with the element added. Other threads therefore see the original collection. The two collections share a lot of internal state, of course -- that's why these persistent structures are efficient. But since different threads see different states of data, it would seem that persistent data structures are not in themselves sufficient to handle scenarios where one thread makes a change that is visible to other threads. For this, it seems we must use devices such as atoms, references, software transactional memory, or even classic locks and synchronization mechanisms. Why then, is the immutability of PDSs touted as something beneficial for "thread safety"? Are there any real examples where PDSs help in synchronization, or solving concurrency problems? Or are PDSs simply a way to provide a stateless interface to an object in support of a functional programming style?

• What do I need to know about Data Structures and Algorithms in the "real" world

  - by Ray T Champion

  I just finished the data structures and algorithms course in school , I took it during the summer so 6wks course vs a 16 wk course during the regular semester. So not only was the course hard but it was really really really fast. My question is what do I need to know about data structures in the real world? I understand what they do and how they work, for the most part, but I had a real tough time coding them , I wouldn't be able to write the code for a binary tree class or a balanced tree class from scratch .... Is that bad? should I retake it , or is knowledge of how they work sufficient, without being able to write the classes from scratch?

• How should compound words be handled when coding? Is there a definitive list of compound words? [closed]

  - by Ray

  QUESTION: How should you handle compound words when programming? Are there any good lists available online for developers of generally accepted technology-related compound words? I can see how this is highly ambiguous, so should I just use common-sense? EXAMPLE: I would be inclined to do this: filename NOT FileName or login NOT LogIn However, the microsoft documentation indicates that filename is not compound. So I wonder, is there a more definitive source? See also, this english.stackexchange discussion on filename. Under the section "Capitalization Rules for Compound Words and Common Terms" located here: Microsoft .NET Capitalization Conventions only offers a limited introduction into the topic, and leaves it up to the developer to use their intuition with the rest.

• Steps to rebuild gspca_kinect driver module?

  - by Bobby Ray

  I recently purchased a Kinect for Windows and quickly discovered that the camera drivers included in linux kernel 3.0+ aren't compatible with the Kinect for Windows hardware revision. After looking at the source code it seems like a tiny modification is all that is required for compatibility, so I've been trying to recompile the driver - to no avail. I've been referring to this article and this one as well, though they are a bit outdated. When I try to compile the module, I get an error because the header file "gspca.h" can't be found in the include path. I located the missing header in my filesystem, but the file itself is empty. I've also tried downloading the kernel source (3.2.0-24-generic), which allowed me to compile the module, but when I load the module I get an error. -1 Unknown symbol in module Is there a standard way to go about this without first building the kernel? Will building the kernel ensure that I can build the module? Thanks

• Keep cube spinning after fling

  - by Zero

  So I've been trying to get started with game development for Android using Unity3D. For my first project I've made a simple cube that you can spin using touch. For that I have the following code: using UnityEngine; using System.Collections; public class TouchScript : MonoBehaviour { float speed = 0.4f; bool canRotate = false; Transform cachedTransform; public bool CanRotate { get { return canRotate; } private set { canRotate = value; } } void Start () { // Make reference to transform cachedTransform = transform; } // Update is called once per frame void Update () { if (Input.touchCount > 0) { Touch touch = Input.GetTouch (0); // Switch through touch events switch (Input.GetTouch (0).phase) { case TouchPhase.Began: if (VerifyTouch (touch)) CanRotate = true; break; case TouchPhase.Moved: if (CanRotate) RotateObject (touch); break; case TouchPhase.Ended: CanRotate = false; break; } } } bool VerifyTouch (Touch touch) { Ray ray = Camera.main.ScreenPointToRay (touch.position); RaycastHit hit; // Check if there is a collider attached already, otherwise add one on the fly if (collider == null) gameObject.AddComponent (typeof(BoxCollider)); if (Physics.Raycast (ray, out hit)) { if (hit.collider.gameObject == this.gameObject) return true; } return false; } void RotateObject (Touch touch) { cachedTransform.Rotate (new Vector3 (touch.deltaPosition.y, -touch.deltaPosition.x, 0) * speed, Space.World); } } The above code works fine. However, I'm wondering how I can keep the cube spinning after the user lifts his finger. The user should be able to "fling" the cube, which would keep spinning and after a while would slowly come to a stop due to drag. Should I do this using AddForce or something? I'm really new to this stuff so I'd like it if you guys could point me in the right direction here :) .

• Setting up group disk quotas

  - by Ray

  I am hoping to get some advice in setting up disk quotas. So, I know about: Adding usrquota and grpquota on to /etc/fstab for the file systems that need to be managed. Using edquota to assign disk quotas to users. However, I need to do the last step for multiple users and edquota seems to be a bit troublesome. One solution that I have found is that I can do: sudo edquota -u foo -p bar. This will copy the disk quota of bar to user foo. I was wondering if this is the best solution? I tried setting up group disk quotas but they don't seem to be working. Are group quotas meant to help in the assignment of the same quota to multiple users? Or are they suppose to give a total limit to a set of users? For example, if users A, B, C are in group X then assigning a quota of 20 GB gives each user 20 GB or does it give 20 GB to the entire group X to divide up? I'm interested in doing the former, but not the latter. Right now, I've assigned group disk quotas and they aren't working. So, I guess it is due to my misunderstanding of group disk quotas... My problem is I want to easily give the same quota to multiple users; any suggestions on the best way to do this out of what I've tried above or anything else I may not have thought of? Thank you!

• How to determine which cells in a grid intersect with a given triangle?

  - by Ray Dey

  I'm currently writing a 2D AI simulation, but I'm not completely certain how to check whether the position of an agent is within the field of view of another. Currently, my world partitioning is simple cell-space partitioning (a grid). I want to use a triangle to represent the field of view, but how can I calculate the cells that intersect with the triangle? Similar to this picture: The red areas are the cells I want to calculate, by checking whether the triangle intersects those cells. Thanks in advance. EDIT: Just to add to the confusion (or perhaps even make it easier). Each cell has a min and max vector where the min is the bottom left corner and the max is the top right corner.

• Is it wrong to use a boolean parameter to determine behavior?

  - by Ray

  I have seen a practice from time to time that "feels" wrong, but I can't quite articulate what is wrong about it. Or maybe it's just my prejudice. Here goes: A developer defines a method with a boolean as one of its parameters, and that method calls another, and so on, and eventually that boolean is used, solely to determine whether or not to take a certain action. This might be used, for example, to allow the action only if the user has certain rights, or perhaps if we are (or aren't) in test mode or batch mode or live mode, or perhaps only when the system is in a certain state. Well there is always another way to do it, whether by querying when it is time to take the action (rather than passing the parameter), or by having multiple versions of the method, or multiple implementations of the class, etc. My question isn't so much how to improve this, but rather whether or not it really is wrong (as I suspect), and if it is, what is wrong about it.

• Desktop empty under Ubuntu 12.04

  - by Ray

  My problem is that my desktop is empty -- there are no files or directories in it. The launcher on the left and the menu at the top are both ok. But, after a recent upgrade from 12.04 to 12.10, everything in my Desktop was emptied. I do have files in my ~/Desktop directory, which is what I want displayed. In ~/.config/user-dirs.dirs, I also have XDG_DESKTOP_DIR="$HOME/Desktop/". Is there something else I should be looking for? I actually have another Ubuntu machine and I don't have the same problem there after upgrading. So, I don't think this is a bug with 12.10 but just some setting (a package, etc.) that was set in one machine but not the other. Oh, I am not sure if this is related to nautilus, but the two machines have the same nautilus-related packages installed... Any help would be appreciated!

• A rocket following the tracks height. Not Homing Missile.

  - by confusedEj

  What I am trying to create is a rocket that will hug the track in a straight direction. ie) The rocket travels in a straight direction and can orientate based on its local x axis. This is so it can go up/down ramps and never hit the ground. Currently I am using PhysX opengl and C++. This is the method I'm trying right now: 1. Ray cast from ahead of the missile (ray casting downwards) 2. If the ray cast is less then the expected ray cast length, then I have to orientate up. 3. If the ray cast is more then the expected ray cast length, then I have to orientate down. Now the problem, I am having is that my missile is orientating at an arbitary angle (I'm giving it 1 degrees.) Though I think this is a bad approach because the amount of frames in the game is not as much as I would think there would be. So the rocket would run into a ramp. My main question is: is there a better way of approaching this and how? NxVec3 frontRayLoc = m_rocketConfig->getValueForKey<NxVec3>("r_frontRayCastLocation"); float threshhold = m_rocketConfig->getValueForKey<float>("r_angleThreshhold"); float predRayCastHeight = m_rocketConfig->getValueForKey<float>("r_predRayCastHeight"); NxVec3 rayGlobalPos_1 = m_actor->getGlobalPosition() + m_actor->getGlobalOrientation() * frontRayLoc; NxVec3 dir = m_actor->getGlobalOrientation() * NxVec3(0,-1.0,0); NxReal dist1 = castRay(rayGlobalPos_1, dir); // Get the percentage difference float actualFrontHeight = abs(1 - (dist1/predRayCastHeight)); // See if the percentage difference is greater then threshold // Also check if we are being shot off track if ((actualFrontHeight > threshhold) && (dist1 != m_rayMaxDist)){ // Dip Down if (dist1 > predRayCastHeight){ printf("DOWN - Distance 1: %f\n", dist1); // Get axis of rotation NxVec3 newAxis = m_actor->getGlobalOrientation() * NxVec3(1.0,0,0.0); // Rotate based on that axis m_orientateAngle = -1.0 * m_orientateAngle; // For rotating clockwise NxQuat newOrientation(m_orientateAngle, newAxis); NxMat33 orientation(newOrientation); m_orientation = m_orientation * orientation; // Orientate the linear velocity to keep speed of rocket and direct away from road NxVec3 linVel = m_actor->getLinearVelocity(); m_actor->setLinearVelocity(m_orientation * linVel); } // Go Up else if (dist1 < predRayCastHeight){ printf("UP - Distance 1: %f\n", dist1); // Get axis of rotation NxVec3 newAxis = m_actor->getGlobalOrientation() * NxVec3(1.0,0,0.0); // Rotate around axis NxQuat newOrientation(m_orientateAngle, newAxis); m_actor->setGlobalOrientationQuat(newOrientation); NxMat33 orientation(newOrientation); m_orientation = m_orientation * orientation; // Orientate the linear velocity to keep speed of rocket and direct away from road NxVec3 linVel = m_actor->getLinearVelocity(); m_actor->setLinearVelocity(m_orientation*linVel); } m_actor->setGlobalOrientation(m_orientation); } Thanks for the support :)

• Can a stylesheet for handhelds skip loading images

  - by Yeoh Ray Mond

  I have a stylesheet for desktops, and another for handhelds. The web page displays some images when displayed on the desktop, but hides those images when displayed on handhelds. The page appears as designed for both desktops and handhelds. When I check the server logs, I find that the handheld is actually still loading the images, just not displaying them. Is there a way to stop the handheld from loading the images entirely, since it doesn't need them, without having to maintain two sets of web pages? Can it be done using just stylesheets? Thanks in advance. Ray Mond
