  • TSQL - make a literal float value

    - by David B
    I understand the host of issues in comparing floats, and lament their use in this case - but I'm not the table author and have only a small hurdle to climb... Someone has decided to use floats as you'd expect GUIDs to be used. I need to retrieve all the records with a specific float value. sp_help MyTable -- Column_name Type Computed Length Prec -- RandomGrouping float no 8 53 Here's my naive attempt: --yields no results SELECT RandomGrouping FROM MyTable WHERE RandomGrouping = 0.867153569942739 And here's an approximately working attempt: --yields 2 records SELECT RandomGrouping FROM MyTable WHERE RandomGrouping BETWEEN 0.867153569942739 - 0.00000001 AND 0.867153569942739 + 0.00000001 -- 0.867153569942739 -- 0.867153569942739 In my naive attempt, is that literal a floating point literal? Or is it really a decimal literal that gets converted later? If my literal is not a floating point literal, what is the syntax for making a floating point literal? EDIT: Another possibility has occurred to me... it may be that a more precise number than is displayed is stored in this column. It may be impossible to create a literal that represents this number. I will accept answers that demonstrate that this is the case. EDIT: response to DVK. TSQL is MSSQLServer's dialect of SQL. This script works, and so equality can be performed deterministically between float types: DECLARE @X float SELECT top 1 @X = RandomGrouping FROM MyTable WHERE RandomGrouping BETWEEN 0.839110948199148 - 0.000000000001 AND 0.839110948199148 + 0.000000000001 --yields two records SELECT * FROM MyTable WHERE RandomGrouping = @X I said "approximately" because that method tests for a range. With that method I could get values that are not equal to my intended value. The linked article doesn't apply because I'm not (intentionally) trying to straddle the world boundaries between decimal and float. I'm trying to work with only floats. This isn't about the non-convertibility of decimals to floats.

  • Fixed div once page is scrolled is flickering

    - by jasondavis
    I am trying to have an advertisement block/div that will be hald way down the page, once you scroll do the page to this point it will stick to the top. Here is a demo of what I am trying to do and the code I am using to do it with... http://jsfiddle.net/jasondavis/6vpA7/3/embedded/result/ In the demo it works perfectly how I am wanting it to be, however when I implement it on my live site, http://goo.gl/zuaZx it works but when you scroll down the div flickers in and out of view on each scroll or down key press. On my site to see the problem live it is the blokc on the right sidebar that says "Recommended Books" Here is the code I am using... $(document).ready( function() { $(window).scroll( function() { if ($(window).scrollTop() > $('#social-container').offset().top) $('#social').addClass('floating'); else $('#social').removeClass('floating'); } ); } );? css #social.floating { position: fixed; top: 0; }? My demo jsfiddle where it works correctly http://jsfiddle.net/jasondavis/6vpA7/3/ The only thing different on my live site is the div/id name is different. As you can see it is somewhat working on my live site except the flickering in and out of view as you scroll down the page. Anyone have any ideas why this would happen on my live site and not on my jsfiddle demo?

  • Top Down RPG Movement w/ Correction?

    - by Corey Ogburn
    I would hope that we have all played Zelda: A Link to the Past, please correct me if I'm wrong, but I want to emulate that kind of 2D, top-down character movement with a touch of correction. It has been done in other games, but I feel this reference would be the easiest to relate to. More specifically the kind of movement and correction I'm talking about is: Floating movement not restricted to tile based movement like Pokemon and other games where one tap of the movement pad moves you one square in that cardinal direction. This floating movement should be able to achieve diagonal motion. If you're walking West and you come to a wall that is diagonal in a North East/South West fashion, you are corrected into a South West movement even if you continue holding left (West) on the controller. This should work for both diagonals correcting in both directions. If you're a few pixels off from walking squarely into a door or hallway, you are corrected into walking through the hall or down the hallway, i.e. bumping into the corner causes you to be pushed into the hall/door. I've hunted for efficient ways to achieve this and have had no luck. To be clear I'm talking about the human character's movement, not an NPC's movement. Are their resources available on this kind of movement? Equations or algorithms explained on a wiki or something? I'm using the XNA Framework, is there anything in it to help with this?

  • MTN WMS Implementation Story

    - by aditya.agarkar
    MTN is Africa's largest cellular phone company serving millions of customers across 21 countries. MTN uses Oracle WMS to manage its distribution activities and its sizzling growth. Just for perspective, since 2004, Africa has been the fastest growing mobile phone market in the world. If you want to know more about MTN and the WMS Project at MTN, a summarized view of MTN WMS project is here. The WMS Project at MTN was presented at Oracle Open World in 2007. The extensive automation at MTN includes interface with Conveyor for item transport, High Speed Sorter for item routing, Put to Light for packing accuracy, ASRS Carousel/Lift for inventory Security and Storage Optimization, Check Weight Scale for shipping accuracy, Automated Carton Erectors for package creation and Automated Carton Labeling. Subsequent to this presentation and their go-live in 2007, the MTN warehouse has scaled new heights. The volume has grown manifolds (as can be expected in a fast growing cellular market). Oracle WMS has been able to scale very well to the increase in volume, just as it was designed to do. Here are a couple of videos that highlight the WMS operations at MTN:  1) Video Interview with Margaretha Theart (Warehouse Manager at MTN) 2) Automation Video at MTN (Hat tip: Syed Imran) Enjoy!

  • Using JuJu with private Openstack cloud deployment?

    - by user76054
    I'm seeing a number of problems trying to use JuJu with our internally deployed Openstack cloud. Most of this appears to be centered around DNS host resolution as well as the need to deal with our company's internal HTTP proxies. Our Openstack deployment relies upon an unroutable 172.16.0.0/12 block of addresses for VLAN allocation to each project (tenant) hosted on our internal cloud. User's have the option of assigning one or more floating addresses to instances, allocated from a block of routable addresses on our internal companies LAN. Currently, Openstack doesn't register instance names with anything other than the DNSMASQ service running on the cloud controller. As such, there's no way to resolve this address through our internal DNS hierarchy (this issue has already been reported as Bug #945505). As such, even though I can bootstrap my JuJu server node, I can't connect to it with the JuJu client, since it can't resolve the local (private) network name. I am able to ssh to the node, once I've assigned it an internally routable (i.e. floating) address. Which leads to the next issue. Next, to install software on an instance running in our cloud, it must have our internal proxy address defined - either in the apt.conf file or via environment variables. Unfortunately, when bootstrapping the server node, there's no provision to pass this info into a instance via JuJu environment.yaml file (if this is even the best way to handle this issue). As a result, the bootstrap node is unable to install the required packages. I'm assuming (dangerous, I know) that the way that I've deployed Openstack in our internal environment is probably not unique. Has anyone else encountered these issues? And more importantly, are work arounds available? Regards, Ross

  • Server 2003 - Default installation of SharePoint throws javascript error 'undefined' is null or not an object

    - by Chris
    I have been handed a server that has a fresh installation of small business server 2003. SharePoint has been installed, and it is a completely fresh copy (no changes made) I know for a fact that everything was paid for so this isn't some dodgy copy. When I try to click any option in any of the floating menu's in IE 8, the browser asks me if I want to debug .. Error: 'undefined' is null or not an object for example, I got to Projects - and click on the sample project, then click delete on the floating menu that pops up and the error appears. This is brand new, I cannot believe I am having this problem! Has anyone come across this, is it an old problem with easy fix? All windows updates installed - see no updates for sharepoint? EDIT: This is WSS2 so I am going to upgrade to WSS3... http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=14117 http://www.techrepublic.com/article/installing-windows-sharepoint-services-30-on-windows-server-2003/6176833 Hopefully this will resolve the problem

  • How do I choose the scaling factor of a 3D game world?

    - by concept3d
    I am making a 3D tank game prototype with some physics simulation, am using C++. One of the decisions I need to make is the scale of the game world in relation to reality. For example, I could consider 1 in-game unit of measurement to correspond to 1 meter in reality. This feels intuitive, but I feel like I might be missing something. I can think of the following as potential problems: 3D modelling program compatibility. (?) Numerical accuracy. (Does this matter?) Especially at large scales, how games like Battlefield have huge maps: How don't they lose numerical accuracy if they use 1:1 mapping with real world scale, since floating point representation tend to lose more precision with larger numbers (e.g. with ray casting, physics simulation)? Gameplay. I don't want the movement of units to feel slow or fast while using almost real world values like -9.8 m/s^2 for gravity. (This might be subjective.) Is it ok to scale up/down imported assets or it's best fit with a world with its original scale? Rendering performance. Are large meshes with the same vertex count slower to render? I'm wondering if I should split this into multiple questions...

  • Javascript: Machine Constants Applicable?

    - by DavidB2013
    I write numerical routines for students of science and engineering (although they are freely available for use by anybody else as well) and am wondering how to properly use machine constants in a JavaScript program, or if they are even applicable. For example, say I am writing a program in C++ that numerically computes the roots of the following equation: exp(-0.7x) + sin(3x) - 1.2x + 0.3546 = 0 A root-finding routine should be able to compute roots to within the machine epsilon. In C++, this value is specified by the language: DBL_EPSILON. C++ also specifies the smallest and largest values that can be held by a float or double variable. However, how does this convert to JavaScript? Since a Javascript program runs in a web browser, and I don't know what kind of computer will run the program, and JavaScript does not have corresponding predefined values for these quantities, how can I implement my own version of these constants so that my programs compute results to as much accuracy as allowed on the computer running the web browser? My first draft is to simply copy over the literal constants from C++: FLT_MIN: 1.17549435082229e-038 FLT_MAX: 3.40282346638529e+038 DBL_EPSILON: 2.2204460492503131e-16 I am also willing to write small code blocks that could compute these values for each machine on which the program is run. That way, a supercomputer might compute results to a higher accuracy than an old, low-level, PC. BUT, I don't know if such a routine would actually reach the computer, in which case, I would be wasting my time. Anybody here know how to compute and use (in Javascript) values that correspond to machine constants in a compiled language? Is it worth my time to write small programs in Javascript that compute DBL_EPSILON, FLT_MIN, FLT_MIN, etc. for use in numerical routines? Or am I better off simply assigning literal constants that come straight from C++ on a standard Windows PC?

  • Modded Portal Gun Levitates a Companion Cube [Video]

    - by Jason Fitzpatrick
    This cleverly designed Portal gun prop levitates a model Companion Cube; the whole setup just begs to be paired with a Halloween costume. Courtesy of Caleb over at Hack A Day: I was out to lunch with a couple friends, brainstorming ideas for fun projects when one of them says “Wouldn’t it be cool if we could build a working gravity gun?”. We all immediately concurred that while it would in fact be cool, it is also a silly proposition. However, only a few seconds later, I realized we could do a display piece that emulated this concept very easily. Floating magnetic globes have been around for quite some time. I determined I would tear the guts out of a stock floating globe and mount it on a portal gun, since they’re easier to find than a gravity gun. I would also build a custom companion cube to be the correct size and weight necessary. Watch the video above and then check out the link below for more information on the build.

  • OpenGL ES 2.0 texture distortion on large geometry

    - by Spruce
    OpenGL ES 2.0 has serious precision issues with texture sampling - I've seen topics with a similar problem, but I haven't seen a real solution to this "distorted OpenGL ES 2.0 texture" problem yet. This is not related to the texture's image format or OpenGL color buffers, it seems like it's a precision error. I don't know what specifically causes the precision to fail - it doesn't seem like it's just the size of geometry that causes this distortion, because simply scaling vertex position passed to the the vertex shader does not solve the issue. Here are some examples of the texture distortion: Distorted Texture (on OpenGL ES 2.0): http://i47.tinypic.com/3322h6d.png What the texture normally looks like (also on OpenGL ES 2.0): http://i49.tinypic.com/b4jc6c.png The texture issue is limited to small scale geometry on OpenGL ES 2.0, otherwise the texture sampling appears normal, but the grainy effect gradually worsens the further the vertex data is from the origin of XYZ(0,0,0) These texture issues do not occur on desktop OpenGL (works fine under Windows XP, Windows 7, and Mac OS X) I've only seen the problem occur on Android, iPhone, or WebGL(which is similar to OpenGL ES 2.0) All textures are power of 2 but the problem still occurs Scaling the vertex data - The values of a vertex's X Y Z location are in the range of: -65536 to +65536 floating point I realized this was large, so I tried dividing the vertex positions by 1024 to shrink the geometry and hopefully get more accurate floating point precision, but this didn't fix or lessen the texture distortion issue Scaling the modelview or scaling the projection matrix does not help Changing texture filtering options does not help Disabling mipmapping, or using GL_NEAREST/GL_LINEAR does nothing Enabling/disabling anisotropic does nothing The banding effect still occurs even when using GL_CLAMP Dividing the texture coords passed to the vertex shader and then multiplying them back to the correct values in the fragment shader, also does not work precision highp sampler2D, highp float, highp int - in the fragment or the vertex shader didn't change anything (lowp/mediump did not work either) I'm thinking this problem has to have been solved at one point - Seeing that OpenGL ES 2.0 -based games have been able to render large-scale, highly detailed geometry

  • Creating Gun objects with upgrades?

    - by zardon
    I have a series of guns in my game. I use the Gun class/object like this: (Just an example) @interface Gun : NSObject { NSString *name; // Six-shooter NSNumber *cost; NSNumber *clipPrice; // ie: 700 NSNumber *clipCapacity; // 6 NSNumber *ammoCapacity; // 6 NSNumber *damage; // 0-10 NSNumber *accuracy; // 0-10 NSNumber *fireRate; // 0-10 NSNumber *range; // 0-10 // Not sure if I have all the stats, but this is fine for now } Lets say I want to have 3 upgrades per gun. My problem is I am not sure how to do this. Examples: increase fire-rate increase range increase accuracy silencer double ammo capacity (ie: Drum) double clip capacity (ie: Taped magazine) Thus my question is, I'd like to implement an upgrade system to guns but I am not sure how to do it. Would there be an Upgrade object which is a child to the Gun class, or would it be seperate class altogether. Thanks for your time.

  • One-way platform collision

    - by TheBroodian
    I hate asking questions that are specific to my own code like this, but I've run into a pesky roadblock and could use some help getting around it. I'm coding floating platforms into my game that will allow a player to jump onto them from underneath, but then will not allow players to fall through them once they are on top, which require some custom collision detection code. The code I have written so far isn't working, the character passes through it on the way up, and on the way down, stops for a moment on the platform, and then falls right through it. Here is the code to handle collisions with floating platforms: protected void HandleFloatingPlatforms(Vector2 moveAmount) { //if character is traveling downward. if (moveAmount.Y > 0) { Rectangle afterMoveRect = collisionRectangle; afterMoveRect.Offset((int)moveAmount.X, (int)moveAmount.Y); foreach (World_Objects.GameObject platform in gameplayScreen.Entities) { if (platform is World_Objects.Inanimate_Objects.FloatingPlatform) { //wideProximityArea is just a rectangle surrounding the collision //box of an entity to check for nearby entities. if (wideProximityArea.Intersects(platform.CollisionRectangle) || wideProximityArea.Contains(platform.CollisionRectangle)) { if (afterMoveRect.Intersects(platform.CollisionRectangle)) { //This, in my mind would denote that after the character is moved, its feet have fallen below the top of the platform, but before he had moved its feet were above it... if (collisionRectangle.Bottom <= platform.CollisionRectangle.Top) { if (afterMoveRect.Bottom > platform.CollisionRectangle.Top) { //And then after detecting that he has fallen through the platform, reposition him on top of it... worldLocation.Y = platform.CollisionRectangle.Y - frameHeight; hasCollidedVertically = true; } } } } } } } } In case you are curious, the parameter moveAmount is found through this code: elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; float totalX = 0; float totalY = 0; foreach (Vector2 vector in velocities) { totalX += vector.X; totalY += vector.Y; } velocities.Clear(); velocity.X = totalX; velocity.Y = totalY; velocity.Y = Math.Min(velocity.Y, 1000); Vector2 moveAmount = velocity * elapsed;

  • Boundary conditions for testing

    - by Loggie
    Ok so in a programming test I was given the following question. Question 1 (1 mark) Spot the potential bug in this section of code: void Class::Update( float dt ) { totalTime += dt; if( totalTime == 3.0f ) { // Do state change m_State++; } } The multiple choice answers for this question were. a) It has a constant floating point number where it should have a named constant variable b) It may not change state with only an equality test c) You don't know what state you are changing to d) The class is named poorly I wrongly answered this with answer C. I eventually received feedback on the answers and the feedback for this question was Correct answer is a. This is about understanding correct boundary conditions for tests. The other answers are arguably valid points, but do not indicate a potential bug in the code. My question here is, what does this have to do with boundary conditions? My understanding of boundary conditions is checking that a value is within a certain range, which isn't the case here. Upon looking over the question, in my opinion, B should be the correct answer when considering the accuracy issues of using floating point values.

  • How to prevent overlapping of gunshot sounds when using fast-firing weapons

    - by G3tinmybelly
    So I am now trying to find sounds for my guns but when I grab a gun sound effect and play it in my game a lot of the sounds are either terrible sounding or have this horrible echoing effect because as a gun shoots sometimes the previous sound is playing still. public void shoot(float x, float y, float direction){ if(empty){ PlayHUD.message = "No more bullets!"; return; } if(reloading){ return; } if(System.currentTimeMillis() - lastShot < fireRate){ //AssetsLoader.lmgSound.stop(); return; } float dx = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); float dx1 = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy1 = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); PlayState.effects.add(new MuzzleFlashEffect(x + dx1, y + dy1, (float) Math.toDegrees(-direction))); PlayState.projectiles.add(new Bullet(this, x + dx, y + dy, (float) (direction + (Math.toRadians(MathUtils.random(-accuracy, accuracy)))))); if(OptionState.soundOn){ AssetsLoader.lmgSound.play(OptionState.volume); } bulletsInClip--; lastShot = System.currentTimeMillis(); } Here is the code for where the sound plays.

  • What is the recommended MongoDB schema for this quiz-engine scenario?

    - by hughesdan
    I'm working on a quiz engine for learning a foreign language. The engine shows users four images simultaneously and then plays an audio file. The user has to match the audio to the correct image. Below is my MongoDB document structure. Each document consists of an image file reference and an array of references to audio files that match that image. To generate a quiz instance I select four documents at random, show the images and then play one audio file from the four documents at random. The next step in my application development is to decide on the best document schema for storing user guesses. There are several requirements to consider: I need to be able to report statistics at a user level. For example, total correct answers, total guesses, mean accuracy, etc) I need to be able to query images based on the user's learning progress. For example, select 4 documents where guess count is 10 and accuracy is <=0.50. The schema needs to be optimized for fast quiz generation. The schema must not cause future scaling issues vis a vis document size. Assume 1mm users who make an average of 1000 guesses. Given all of this as background information, what would be the recommended schema? For example, would you store each guess in the Image document or perhaps in a User document (not shown) or a new document collection created for logging guesses? Would you recommend logging the raw guess data or would you pre-compute statistics by incrementing counters within the relevant document? Schema for Image Collection: _id "505bcc7a45c978be24000005" date 2012-09-21 02:10:02 UTC imageFileName "BD3E134A-C7B3-4405-9004-ED573DF477FE-29879-0000395CF1091601" random 0.26997075392864645 user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioFiles [ 0 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "English" date 2012-09-22 01:15:04 UTC } 1 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "Spanish" date 2012-09-22 01:17:04 UTC } ]

  • jQuery Cycle plugin z-index float problem

    - by Antony Carthy
    When I try to place an element on top of my jQuery Cycle element, it doesn't work. The element is always behind the jQuery cycle element. I use float: right; to position the element, and set its z-index to 100000, to no avail. Firebug sees the Cycle element and its children as having low z-indexes, and shows the floating element to be in the right place. The element never shows above the Cycling images. <!-- the cycling set --> <div id='headerimages'> <img src='images/header1.jpg' alt='' style='' /> <img src='images/header2.jpg' alt='' style='' /> <img src='images/header3.jpg' alt='' style='' /> </div> <!-- the floating element --> <img src='images/logotransparent.png' alt='' id='logo' />

  • WPF assign Z-Order of owned windows without changing focus.

    - by Kamiikoneko
    Hi, Due to OpenGL airspace issues I have several windows that are owned by the main window but look and act like controls. I also have some data readout/sort windows that show real-time data and need to be normal floating windows, also owned by the main window so that they remain floating above the main window even while operations are performed in the main window. The issue: I open a data readout window (normal window) and am watching data change. Then I click on a text box to enter a value in one of the windows that acts as a control due to airspace issues, and it becomes activated, covering up my data readout window. This is bad because the airspace window is supposed to act like it is part of the main window. I tried some tricks with Activation and Deactivation, and it looks ok but then editing the airspace window at all is impossible because WPF only lets me edit the activated window. How can I ask that normal data readout window to please stay above all other windows owned by the main window, but still let other windows receive focus?

  • WPF: How to get the event when one FrameworkElement comes in contact with other FrameworkElement

    - by Raghav
    I am developing a small application with images and trash box icon on right hand bottom. I have multiple images floating in the main window, and using mouse I can move image from one corner to other corner of window, left, right, top and bottom. I can't figure out how do I catch an event when a image touches and panel (with trash box image), in the right hand corner. Does anybody knows which event or handler to listen? This is not a drag and drop case since my images are floating so no point using drag and drop. Thank you

  • iPhone SDK: CLocationAccuracy. What constants map to what positioning technology?

    - by buzzappsoftware
    With respect to CLocationManager docs.... Constant values you can use to specify the accuracy of a location. extern const CLLocationAccuracy kCLLocationAccuracyBestForNavigation; extern const CLLocationAccuracy kCLLocationAccuracyBest; extern const CLLocationAccuracy kCLLocationAccuracyNearestTenMeters; extern const CLLocationAccuracy kCLLocationAccuracyHundredMeters; extern const CLLocationAccuracy kCLLocationAccuracyKilometer; extern const CLLocationAccuracy kCLLocationAccuracyThreeKilometers; Given that, I have the following questions. What triangulation method (GPS, cell tower or wi-fi) corresponds to each accuracy level? Does iPhone SDK utilize Skyhook Wireless API? For kCLLocationAccuracyBestForNavigation, there is note stating the phone must be plugged in. Is this enforced or is it just warning the developer the battery is likely to drain quick from using the GPS receiver. Thanks in advance.

  • How was non-decimal money represented in software?

    - by dan04
    A lot of the answers to the questions about the accuracy of float and double recommend the use of decimal for monetary amounts. This works because today all currencies are decimal except MGA and MRO, and those have subunits of 1/5 so are still decimal-friendly. But what about the software used in U.S. stock markets when prices were in 1/16ths of dollar? The accuracy of binary data types wouldn't have been an issue, right? Going further back, how did pre-1971 British accounting software deal with pounds, shillings, and pence? Did their versions of COBOL have a special PIC clause for it? Were all amounts stored in pence? How was decimalisation handled?

  • How do I use modulus for float/double?

    - by ShrimpCrackers
    I'm creating an RPN calculator for a school project. I'm having trouble with the modulus operator. Since we're using the double data type, modulus won't work on floating point numbers. For example, 0.5 % 0.3 should return 0.2 but I'm getting a division by zero exception. The instruction says to use fmod(). I've looked everywhere for fmod(), including javadocs but I can't find it. I'm starting to think it's a method I'm going to have to create? edit: hmm, strange. I just plugged in those numbers again and it seems to be working fine...but just in case. Do I need to watch out using the mod operator in Java when using floating types? I know something like this can't be done in C++ (I think).
