  • Running 32-bit SSIS in a 64-bit Environment

    - by John Paul Cook
    After my recent post on where to find the 32-bit ODBC Administrator on a 64-bit SQL Server, a new question was asked about how to get SSIS to run with the 32-bit ODBC instead of the 64-bit ODBC. You need to make a simple configuration change to the properties of your BIDS solution. Here I have a solution called 32bitODBC and it needs to run in 32-bit mode, not 64-bit mode. Since I have a 64-bit SQL Server, BIDS defaults to using the 64-bit runtime. To override this setting, go to the property pages...(read more)

  • *DX11, HLSL* - Colour as 4 floats or one UINT

    - by Paul
    With the DX11 pipeline, would it be much quicker for the vertex buffer to pass one single UINT with one byte per channel to the input assembler, as opposed to three floats? Then the vertex shader would convert the four bytes to four floats, which I guess is the required colour format for the pipeline. In this instance, colour accuracy isn't an issue. The vertex buffer would need to be updated many times per frame, so using a single UINT and saving 12 bytes for every vertex could well be worth it: quicker uploads to vram and also less memory used. But the cost is the extra shader work for every vertex to convert each 8 bits of the input UNIT into a float. Anyone have an idea if it might be worth doing? Or, is it possible for the pipeline to be set to just internally use a four-byte colour format? The swap chain buffer has been initialised as DXGI_FORMAT_R8G8B8A8_UNORM, so ultimately that's how the colour will be written. Thanks!

  • Future of Programmers [closed]

    - by Brian Paul
    Possible Duplicate: Will programmers be around in a few years? I have a passion of web development, but have been wondering of late, what is the future of web programming, and just programming in general. I will give an example to illustrate this, companies now most of them buy/ are willing to spend more money to implement enterprise level products, coming from big companies, than hiring a programmer, because when you look at the long term,instead of paying this programmer, and being tied to his ideas and skills, better buy a product, which you are guaranteed high level functions and support. Therefore what will be the future to programmers?

  • Rotating object along bezier curve: not rotating enough?

    - by Paul
    I tried to follow the instructions from the threads on the forum (Cocos2d rotating sprite while moving with CCBezierBy) with Unity, in order to rotate my object as it moves along a bezier curve. But it does not rotate enough, the angle is too low, it goes up to 6 instead of 90 for example, as you can see on this image (the y eulerAngle is at 6, I would expect it to be around 90 with this curve) : Would you know why it does this? And how to make the rotation toward the next point? Here is the code (in c# with Unity) : (I am comparing x and z to get the angle, and adding the angle to eulerAngles.y so that it rotates around the y axis) void Update () { if ( Input.GetKey("d") ) start = true; if ( start ){ myTime = Time.time; start = false; } float theTime = (Time.time - myTime) *0.5f; if ( theTime < 1 ) { car.position = Spline.Interp( myArray, theTime );//creates the bezier curve counterBezier += Time.deltaTime; //compare 2 positions after 0.1f if ( counterBezier > 0.1f ){ counterBezier = 0; cbDone = false; newpos = car.position; float angle = Mathf.Atan2(newpos.z - oldpos.z, newpos.x - oldpos.x); angle += car.eulerAngles.y; car.eulerAngles = new Vector3(0,angle,0); } else if ( counterBezier > 0 && !cbDone ){ oldpos = car.position; cbDone = true; } Thanks

  • External drive hanging, load average through the roof

    - by Paul Tomblin
    I have an external USB drive, and I run an hourly rsync to it as a backup. This has been working fine for years. This weekend, I got two new 2Tb internal drives, and decided it was time to re-install Ubuntu from scratch to clear out all the old cruft. About once a day since the re-install, the backup script hangs hard, usually in the "rm -rf" I do before the rsync. By the time I notice the problem, my load average is in the stratosphere and climbing fast (one time, it was over 150), but anything that doesn't touch the drive seems to be running fine. One thing that I find suspicious is that something, I don't know what, is doing a "smartctl" and a "hdparm" command on the USB drive. I'm pretty sure smartctl isn't supposed to run on external drives. I can't figure out what's doing it, either. Here's part of ps auwwfx when it's hung: root 7310 0.0 0.0 4248 352 ?

  • Unity: Spin wheels to move vehicle

    - by Paul Manta
    I am just getting started with Unity and I'd like to ask a question. If I have a "Vehicle" object that has two children: "FrontWheel" and "BackWheel" (both 'wheels' are cylinders), how should I set everything up such that I can move the entire vehicle by turning its wheels? When I apply a torque to "FrontWheel", the vehicle starts to move, but instead of the whole thing the moving together, the chassis is rolling on the cylinders and eventually falls off. How can I prevent it from doing that?

  • Cheating Incident

    - by Paul Sorensen
    Hi Everyone -I just wanted to give you a heads-up on some recent actions that we had to take regarding someone who tried to cheat on a test.Just last week, we had a candidate who was bold enough to try to take screen-shots during the exam using his cell phone. Of course this is completely against Oracle Certification Program policy. This candidate's exam was immediately stopped, and the candidate was ejected from the testing center.Of course it doesn't end there. This candidate was also suspended permanently from the Oracle Certification Program, and all of his previous certifications were revoked. He is no longer eligible to participate in the program. Unfortunately - if this candidate works for an Oracle partner company, then his company will also likely become aware of his indiscretion - particularly when they request validation of his certification.Although this particular candidate was blatantly involved in content theft, any type of cheating incident is very unfortunate. It erodes the value of the certification credentials, and hurts everyone involved. The actions described above represent our efforts to curb cheating and maintain the value of Oracle certification credentials.I encourage anyone seeking Oracle certification to carefully read and adhere to the Oracle Certification Program Fraudulent Activity Policy.Thanks,QUICK LINKSOracle Certification Program Candidate Agreement (PDF 155K)Oracle Certification Program Fraudulent Activity Policy

  • Great Blog Comments

    - by Paul Sorensen
    Just a quick note to let you know that in the interest of keeping the most useful content available here on the Oracle Certification Blog, we do moderate the comments. We welcome (and encourage dialog, questions, comments, etc) here on the topics at hand. We'll never 'censor' out a comment just because we don't like it - in fact, this is how we often learn ways in which we can do better. But of course we will filter out the typical list like anyone else: crude/offensive remarks, foul language, reference to illegal activity, etc. We will also often redirect any customer-service type inquiries to [email protected] where they can best be handled.Also, if you have a question of a general nature, please research it on the Oracle Certification website first. We often won't respond to questions asking such as "tell me how to get 11g ocp", as we've already made sure that you have that kind of information available. Now if we've inadvertently 'hidden' something on our site (gulp), then fair enough - please let us know that you're having a hard time finding it and we'll be sure to try and "unbury it" ;-)Additionally, you may have more of an 'opinion' type question, such as "should I do 'x' certification or 'y' certification." For these, we highly recommend checking on the Oracle Technology Network (OTN) Certification Forum, where you can engage in peer-to-peer discussions, share techniques, advice and best practices with others in the field.In the meantime, please continue to share your thoughts, ideas, opinions, tech tips etc - we look forward to seeing them and passing them wherever we can!QUICK LINKS:Oracle Certification WebsiteEmail - Customer ServiceOracle Technology Network (OTN) Certification Forum

  • Is it bad practice for services to share a database in SOA?

    - by Paul T Davies
    I have recently been reading Hohpe and Woolf's Enterprise Integration Patterns, some of Thomas Erl's books on SOA and watching various videos and podcasts by Udi Dahan et al. on CQRS and Event Driven systems. Systems in my place of work suffer from high coupling. Although each system theoretically has its own database, there is a lot of joining between them. In practice this means there is one huge database that all systems use. For example, there is one table of customer data. Much of what I've read seems to suggest denormalising data so that each system uses only its database, and any updates to one system are propagated to all the others using messaging. I thought this was one of the ways of enforcing the boundaries in SOA - each service should have its own database, but then I read this: http://stackoverflow.com/questions/4019902/soa-joining-data-across-multiple-services and it suggests this is the wrong thing to do. Segregating the databases does seem like a good way of decoupling systems, but now I'm a bit confused. Is this a good route to take? Is it ever recommended that you should segregate a database on, say an SOA service, an DDD Bounded context, an application, etc?

  • Temporary Tables in Stored Procedures

    - by Paul White
    Ask anyone what the primary advantage of temporary tables over table variables is, and the chances are they will say that temporary tables support statistics and table variables do not. This is true, of course; even the indexes that enforce PRIMARY KEY and UNIQUE constraints on table variables do not have populated statistics associated with them, and it is not possible to manually create statistics or non-constraint indexes on table variables. Intuitively, then, any query that has alternative execution...(read more)

  • Advantages and disadvantages of libgdx [on hold]

    - by Paul
    I've been an android developer for a while and am thinking about getting into gaming. While looking for a game dev framework, I thought libgdx provides very friendly documentation and functionality. So I would like to use it if there is no big obstacle. But when I tried to see how many developers employ this library, I could find not that many. Is there anything wrong with this library? In other words, I would like to know its advantages or disadvantages from any experienced developer. UPDATE: After reviewing its documentations and trying to build simple games with libgdx, I decided to go with it as its documentations are good enough and its community is very active. What I liked the most is that it provides a bunch of demo games that I can learn a lot from.

  • convert image to spritesheet of tiles for isometric map?

    - by Paul
    is there a way to convert an isometric image (like the first image) to a spritesheet (like the second image), in order to place each image on the isometric map with the code? The map looks like the first image, but some buildings are bigger than just one tile, so I need several squares (let's say the first image is a building, made of multiple tiles with different colors), and each square is placed with an offset of 64x32. The building is created in Blender and I save the image with the isometric perspective. But I have to split each square from this image in order to have the spritesheet, maybe there is smarter way, or a java software that would make the conversion for me?

  • Accessing Repositories from Domain

    - by Paul T Davies
    Say we have a task logging system, when a task is logged, the user specifies a category and the task defaults to a status of 'Outstanding'. Assume in this instance that Category and Status have to be implemented as entities. Normally I would do this: Application Layer: public class TaskService { //... public void Add(Guid categoryId, string description) { var category = _categoryRepository.GetById(categoryId); var status = _statusRepository.GetById(Constants.Status.OutstandingId); var task = Task.Create(category, status, description); _taskRepository.Save(task); } } Entity: public class Task { //... public static void Create(Category category, Status status, string description) { return new Task { Category = category, Status = status, Description = descrtiption }; } } I do it like this because I am consistently told that entities should not access the repositories, but it would make much more sense to me if I did this: Entity: public class Task { //... public static void Create(Category category, string description) { return new Task { Category = category, Status = _statusRepository.GetById(Constants.Status.OutstandingId), Description = descrtiption }; } } The status repository is dependecy injected anyway, so there is no real dependency, and this feels more to me thike it is the domain that is making thedecision that a task defaults to outstanding. The previous version feels like it is the application layeer making that decision. Any why are repository contracts often in the domain if this should not be a posibility? Here is a more extreme example, here the domain decides urgency: Entity: public class Task { //... public static void Create(Category category, string description) { var task = new Task { Category = category, Status = _statusRepository.GetById(Constants.Status.OutstandingId), Description = descrtiption }; if(someCondition) { if(someValue > anotherValue) { task.Urgency = _urgencyRepository.GetById (Constants.Urgency.UrgentId); } else { task.Urgency = _urgencyRepository.GetById (Constants.Urgency.SemiUrgentId); } } else { task.Urgency = _urgencyRepository.GetById (Constants.Urgency.NotId); } return task; } } There is no way you would want to pass in all possible versions of Urgency, and no way you would want to calculate this business logic in the application layer, so surely this would be the most appropriate way? So is this a valid reason to access repositories from the domain?

  • How to position a sprite in a 2D animation skeleton?

    - by Paul Manta
    Given two joints that define a bone, I would like to know how to decide where, between those two joints, I should draw the sprite. This should be a fairly simple thing to solve, but there is one thing that I am not sure about. After I've determined the rotation of the sprite (which is the absolute angle the joints form with the x-axis), I also need to determine the origin point from where I need to start drawing the transformed image. So how should I position the sprite between the two joints? Should I make the center of the image be the midpoint between the two joints, or should I make one the of the joints be the origin? Do these things matter that much (could the wrong positioning make the sprite move oddly during the animation)?
