  • 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)?

  • text is not appearing at cursor in bash, can I reset it somehow?

    - by jcollum
    This happens sometimes if the VM bumps up against upper limits of memory and has to hit swap heavily for extended periods (a few minutes or more). When this happens and I type asdf at the prompt it looks like: $ No command 'asdf' found, did you mean: Command 'asdfg' from package 'aoeui' (universe) Command 'sadf' from package 'sysstat' (main) Command 'sdf' from package 'sdf' (universe) asdf: command not found $ Note that asdf isn't showing up after $. The obvious answer is to just kill the tab and start a new one. Still, I have to wonder if there's a way to reset a bash terminal that is misbehaving like this. I tried bash and it didn't make any difference.

  • Rotate view matrix based on touch coordinates

    - by user1055947
    I'm working on an Android game where I need to rotate the camera around the origin based on the user dragging their finger. My view matrix has initial position of sitting on the negative z and facing origin. I have succeeded in moving the camera through rotation left or right, up or down based on the user dragging the finger, but my problem is obviously that after I drag my finger up/down and rotate say 90 degrees so my intial position of -z is now +y and still facing origin, if I drag my finger left/right I want to rotate from +y to +x, but what happens is it rotates around the pole +y. This is to be expected as I am mapping 2D touch drag coords to 3D space, but I dont know where to start trying to do what I want. Perhaps someone can point me in the right direction, I've been googling for a while now but I don't know what I want to do is called! Edit __ What I was looking for is called an ArcBall, google it for lots of info on it.

  • Questions to ask a 3rd party API provider

    - by Jarede
    I'm due to meet with a developer/sales person from a new 3rd party resource we're about to start using. The main topic I'll be interested in, is their API as I will be the developer making use of it and explaining it to the rest of the team. What questions would you recommend asking? Things I'm already thinking about are: What happens and how will I be notified when they depreciate a method? Is there ever any downtime? Who will I deal with first when I have API issues?

  • Which Java web framework do you recommend for intranet webapp (not content website)?

    - by pregzt
    I'm about to start development of small purpose build intranet web application for small software vendor. It will be administration console of the server managing licenses for off-the-shelf software installed by users. There will be a few users who need to be able to sign in, issue a batch of license codes, revoke some, renew outdated, resolve issues, etc. Bear in mind that my customer requires Java for this solution. I'm seasoned Java programmer and before I used different frameworks to implement webapps, mainly Apache Struts in the past and Spring MVC recently. I was wondering what else could you recommend for such specific intranet webapp. I looked at using Google Web Toolkit (possibly with SmartGWT) Ext JS for fancy widgets in UI and REST back-end in SpringMVC SpringMVC with JQueryUI Could you please think of any piece of recommendation with regard to the choice I'm going to made?

  • Byte Size Tips: How to Stop OS X from Changing the Display Brightness Automatically

    - by The Geek
    After getting a new MacBook Air and deciding to try out OS X for a while, I started wondering why the battery would suddenly start dying really fast, but only when I was sitting at the kitchen table. That’s when I noticed the display brightness kept changing on its own… and realized the problem. OS X, just like your phone, and any modern device, tries to figure out the brightness of the room you’re in, and adjust the brightness of the screen. If you are over in Windows, it’s called “Adaptive” brightness, while your phone will just call it “Auto”. While this technology is great in theory, I don’t really need max brightness all the time, and I like to control it manually to make sure I’m getting the best battery life. Open up System Preferences, head to Displays. Then uncheck the Automatically adjust brightness setting.

  • The Basics of Project Management / Software Development

    - by Sam
    It suddenly struck me today that I have never developed any large application or worked with a team of programmers, and so am missing out a lot - both in terms of technical knowledge and the social-fun part of it. And I would like to rectify that - an idea is to start an open source group by training college students (for no charge) and developing some open source application with them. Please give me some basic advice on the whole process of how to (1) plan and (2) manage projects in a team. What new skill sets would you recommend? (I have read joel on software and 37 Signals, and got many insightful tips from them. But I'd like a little more technical knowledge ...) Background (freelancer, past 4+ years) - Computer engineer graphic / web designer online marketing moved on to programming in PHP, Perl, Python did Oracle DBA OCP training to understand DB's current self-assigned title - web application developer.

  • Rip and Convert DVD’s to an ISO Image

    - by Mysticgeek
    If you own a lot of DVD’s, you might want to convert them to an ISO image for backup and easily playing them on your media center. Today we take a look at ripping your discs using DVDFab, then using ImgBurn to create an ISO image of the ripped DVD files. Rip DVD with DVDFab6 DVDFab will remove copy protection and rip the DVD files for free. Other components in the suite require you to purchase a license after the 30 day trial, but you’ll still be able to rip DVD’s after the trial. Install DVDFab by accepting the defaults (link below)…a system restart is required to complete the install process. The first time you run it, a welcome screen is displayed. If you don’t want to see it again check the box Do not show again, then Start DVDFab.  Pop the DVD in your drive and click Next. Now select your region and check Do not show again, then OK. It will then open the DVD and begin to scan it. Under DVD to DVD you can select either Full Disc or Main Movie depending on what you want to rip. If you want to burn the DVD to a disc after it’s created select the Full Disc option. Now click the Start button to begin the ripping process. After the ripping process has completed, you’ll get a message telling you it’s waiting for you to put in a blank DVD. Since we aren’t burning the disc, just cancel the message. Click Finish and close out of DVDFab or just minimize it if you’re going to keep using it to rip another DVD. By default the temporary directory is in My Documents \ DVDFab \ Temp…however you can change it in settings. If you go to the Temp directory you’ll see the DVD files listed there… Convert Files to ISO with ImgBurn Now that we have the files ripped from the DVD, we need to convert them to an ISO image using ImgBurn (link below). Open it up and from the main menu click on Create image file from files/folders. Click on the folder icon to browse to the location of the ripped DVD files. Browse to the DVDFab temp directory and the VIDEO_TS folder for the source and click Ok. Then choose a destination directory, give the ISO a name, and click Save. In this case we ripped the Unbreakable DVD, so named it that.   So now in ImgBurn you have the source being the ripped DVD files, and the destination for the ISO…then click the Build button. If you don’t create a volume label, ImgBurn is kind enough to create on for you. If everything looks correct, click Ok. Now wait while ImgBurn goes through the process of converting the ripped DVD files to an ISO image. The process has successfully completed. The ISO image of the DVD will be in the output directory you selected earlier. Now you can burn the ISO image to a blank DVD or store it on an external hard drive for safe keeping. When you’re done, you’ll probably want to go into the temp DVDFab folder and delete the VOB and other files in the Video_TS folder as they will take up a lot of space on your hard drive.   Conclusion Although this method requires two programs to make an ISO out of a DVD, it’s extremely quick. When burning DVD’s of various lengths, it took less than 30 minutes to get the final ISO. Now, you’ll have your DVD movies backed up in case something were to happen to the discs and are no longer playable. If you use Windows Media Center to watch your movies, check out our article on how to automatically mount and view ISO files in Windows 7 Media Center. With DVDFab, you get a 30 day fully functional trial for all of its features. You’ll still be able rip DVD’s even after the 30 day trial has ended. The more we’ve been using DVDFab, the more impressed we are with its capabilities, so after the 30 day trial you should consider purchasing a license. We will have a full review of the of it to share with you soon.  Download DVDFab Download ImgBurn Similar Articles Productive Geek Tips How To Rip DVDs with VLCCalculate with Qalculate on LinuxConvert a Row to a Column in Excel the Easy WayEnjoy Quick & Easy Unit Conversion with Convert for WindowsConvert Older Excel Documents to Excel 2007 Format TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional Beware Hover Kitties Test Drive Mobile Phones Online With TryPhone Ben & Jerry’s Free Cone Day, 3/23/10 New Stinger from McAfee Helps Remove ‘FakeAlert’ Threats Google Apps Marketplace: Tools & Services For Google Apps Users Get News Quick and Precise With Newser

  • Literature for Inverse Kinematics: Joint Limits and beyond

    - by Jeff
    Recently I've been playing around with Inverse Kinematics and have been pretty impressed with the results. Naturally I want to take it further, but have no clue where to start. In particular, I would like to introduce joint limits (ie for a prismatic joint how far it can move, hinge joint what angles it has to be between, etc etc). Currently I understand how to produce the Jacobian matrix for the various joint types. I am particularly looking for literature (preferably free, and preferably easy to understand) on various ways to implement joint limits. Also I would like to find out different ideas on how inverse kinematics can be used.

  • Set a Video as Your Desktop Wallpaper with VLC

    - by DigitalGeekery
    Are you tired of static desktop wallpapers and want something a bit more entertaining? Today we’ll take a look at setting a video as wallpaper in VLC media player. Download and install VLC player. You’ll find the download link below. Open VLC and select Tools > Preferences. On the Preferences windows, select the Video button on the left. Under Video Settings, select DirectX video output from the Output dropdown list. Click Save before exiting and then restart VLC. Next, select a video and begin playing it with VLC. Right-click on the screen, select Video, then DirectX Wallpaper.   You can achieve the same result by selecting Video from the Menu and clicking DirectX Wallpaper.   If you’re using Windows Aero Themes, you may get the warning message below and your theme will switch automatically to a basic theme.   After the Wallpaper is enabled, minimize VLC player and enjoy the show as you work.     When you are ready to switch back to your normal wallpaper, click Video, and then close out of VLC.   Occasionally we had to manually change our wallpaper back to normal. You can do that by right clicking on the desktop and selecting your theme.   Conclusion This might not make the most productive desktop environment, but it is pretty cool. It’s definitely not the same old boring wallpaper!

  • Introducing sp_ssiscatalog (v1.0.0.0)

    - by jamiet
    Regular readers of my blog may know that over the last year I have made available a suite of SQL Server Reporting Services (SSRS) reports that provide visualisations of the data in the SQL Server Integration Services (SSIS) 2012 Catalog. Those reports are available at http://ssisreportingpack.codeplex.com. As I have built these reports and used them myself on a real life project a couple of things have dawned on me: As soon as your SSIS Catalog gets a significant amount of data in it the performance of the reports degrades rapidly. This is hampered by the fact that there are limitations as to the SQL statements that I can embed within a SSRS report. SSIS professionals are data guys at heart and those types of people feel more comfortable in a query environment rather than having to go through the rigmarole of standing up a reporting server (well, I know I do anyway) Hence I have decided to take a different tack with the reporting pack. Taking my lead from Adam Machanic’s sp_whoisactive and Brent Ozar’s sp_blitz I have produced sp_ssiscatalog, a stored procedure that makes it easy to get at the crucial data in the SSIS Catalog. I will spend the rest of this blog explaining exactly what sp_ssiscatalog does and how to use it but if you would rather just download the bits yourself and start to play you can download v1.0.0.0 from DB v1.0.0.0. Usage Scenarios Most Recent Execution I find that the most frequent information that one needs to get from the SSIS Catalog is information pertaining to the most recent execution. Hence if you execute sp_ssiscatalog with no parameters, that is exactly what you will get. EXEC [dbo].[sp_ssiscatalog] This will return up to 5 resultsets: EXECUTION - Summary information about the execution including status, start time & end time EVENTS - All events that occurred during the execution OnError,OnTaskFailed - All events where event_name is either OnError or OnTaskFailed OnWarning - All events where event_name is OnWarning EXECUTABLE_STATS - Duration and execution result of every executable in the execution All 5 resultsets will be displayed if there is any data satisfying that resultset. In other words, if there are no (for example) OnWarning events then the OnWarning resultset will not be displayed. The display of these 5 resultsets can be toggled respectively by these 5 optional parameters (all of which are of type BIT): @exec_execution @exec_events @exec_errors @exec_warnings @exec_executable_stats Any Execution As just explained the default behaviour is to supply data for the most recent execution. If you wish to specify which execution the data should return data for simply supply the execution_id as a parameter: EXEC [dbo].[sp_ssiscatalog] 6 All Executions sp_ssiscatalog can also return information about all executions: EXEC [dbo].[sp_ssiscatalog] @operation_type='execs' The most recent execution will appear at the top. sp_ssiscatalog provides a number of parameters that enable you to filter the resultset: @execs_folder_name @execs_project_name @execs_package_name @execs_executed_as_name @execs_status_desc Some typical usages might be: //Return all failed executions EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_status_desc='failed' //Return all executions for a specified folder EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_folder_name='My folder' //Return all executions of a specified package in a specified project EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_project_name='My project', @execs_package_name='Pkg.dtsx' Installing sp_ssicatalog Under the covers sp_ssiscatalog actually calls many other stored procedures and functions hence creating it on your server is not simply a case of running a CREATE PROCEDURE script. I maintain the code in an SQL Server Data Tools (SSDT) database project which means that you have two ways of obtaining it. Download the source code You can download the latest (at the time of writing) source code from http://ssisreportingpack.codeplex.com/SourceControl/changeset/view/70192. Hit the download button to download all the source code in a zip file. The contents of that zip file will include an SSDT database project which you can open up in SSDT and publish just like any other SSDT database project. You can publish to a new database or any existing database, even [SSISDB] if you prefer. Download a dacpac Maintaining the code in an SSDT database project means that it can all get packaged up into a dacpac that you can then publish to your SQL Server. That dacpac is available from DB v1.0.0.0: Ordinarily a dacpac can be deployed to a SQL Server from SSMS using the Deploy Dacpac wizard however in this case there is a limitation. Due to sp_ssiscatalog referring to objects in the SSIS Catalog (which it has to do of course) the dacpac contains a SqlCmd variable to store the name of the database that underpins the SSIS Catalog; unfortunately the Deploy Dacpac wizard in SSMS has a rather gaping limitation in that it cannot deploy dacpacs containing SqlCmd variables. Hence, we can use the command-line tool, sqlpackage.exe, instead. Don’t worry if reverting to the command-line sounds a little daunting, I assure you it is not. Simply open a Visual Studio command-prompt and cd to the folder containing the downloaded dacpac: Type: "%PROGRAMFILES(x86)%\Microsoft SQL Server\110\DAC\bin\sqlpackage.exe" /action:Publish /TargetDatabaseName:SsisReportingPack /SourceFile:SSISReportingPack.dacpac /Variables:SSISDB=SSISDB /TargetServerName:(local) or the shortened form: "%PROGRAMFILES(x86)%\Microsoft SQL Server\110\DAC\bin\sqlpackage.exe" /a:Publish /tdn:SsisReportingPack /sf:SSISReportingPack.dacpac /v:SSISDB=SSISDB /tsn:(local) remembering to set your server name appropriately (here mine is set to “(local)” ). If everything works successfully you will see this: And you’re done! You’ll have a new database called [SsisReportingPack] which contains sp_ssiscatalog:   Good luck with sp_ssiscatalog. I have been using it extensively on my own projects recently and it has proved to be very useful indeed. Rest-assured however, I will be adding many new capabilities in the future. Feedback is welcome. @Jamiet

  • What algorithm can I use to detect simple shapes in a 4x4 matrix?

    - by ion
    I'm working on a simple multiplayer game that receives a random 4x4 matrix from a server and extracts a shape from it. For example: XXOO OXOO XXOX XXOO XOOX and XOOO XXXX OXXX So in the first matrix the shape I want to parse is: oo o oo and the 2nd: oo oo ooo I know there must be an algorithm for this because I saw this kind of behavior on some puzzle games but I have no idea how to go about to detecting them or even where to start. So my question is: How do I detect what shape is in the matrix and how do I differentiate between multiple colors? (it doesn't come only in X and O, it comes in a maximum of 4). Additionally, the shape must be a minimum of 4 blocks.

  • Nicest way to map rgb colors from html to led

    - by back_ache
    I have attached an rgb led to a color picker on a webpage and have hit the obvious problem that though the led is 8-bit like html the color rendition is very different so with the more subtle shades the led values for the color are wildly different to the html values. The brute-force method would be for me to have a lookup-table on the webserver to map the two sets of values but would ideally like to do it more elegantly Before I start listing all my 101 ideas for doing this I wondered if anyone else had come across the issue, the end-game would be to be able to abstract the color-rendition of different leds and make it available as a webservice (html value and device id in, led value out)

  • How To Get Web Site Thumbnail Image In ASP.NET

    - by SAMIR BHOGAYTA
    Overview One very common requirement of many web applications is to display a thumbnail image of a web site. A typical example is to provide a link to a dynamic website displaying its current thumbnail image, or displaying images of websites with their links as a result of search (I love to see it on Google). Microsoft .NET Framework 2.0 makes it quite easier to do it in a ASP.NET application. Background In order to generate image of a web page, first we need to load the web page to get their html code, and then this html needs to be rendered in a web browser. After that, a screen shot can be taken easily. I think there is no easier way to do this. Before .NET framework 2.0 it was quite difficult to use a web browser in C# or VB.NET because we either have to use COM+ interoperability or third party controls which becomes headache later. WebBrowser control in .NET framework 2.0 In .NET framework 2.0 we have a new Windows Forms WebBrowser control which is a wrapper around old shwdoc.dll. All you really need to do is to drop a WebBrowser control from your Toolbox on your form in .NET framework 2.0. If you have not used WebBrowser control yet, it's quite easy to use and very consistent with other Windows Forms controls. Some important methods of WebBrowser control are. public bool GoBack(); public bool GoForward(); public void GoHome(); public void GoSearch(); public void Navigate(Uri url); public void DrawToBitmap(Bitmap bitmap, Rectangle targetBounds); These methods are self explanatory with their names like Navigate function which redirects browser to provided URL. It also has a number of useful overloads. The DrawToBitmap (inherited from Control) draws the current image of WebBrowser to the provided bitmap. Using WebBrowser control in ASP.NET 2.0 The Solution Let's start to implement the solution which we discussed above. First we will define a static method to get the web site thumbnail image. public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight) { WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight); return thumbnailGenerator.GenerateWebSiteThumbnailImage(); } The WebsiteThumbnailImage class will have a public method named GenerateWebSiteThumbnailImage which will generate the website thumbnail image in a separate STA thread and wait for the thread to exit. In this case, I decided to Join method of Thread class to block the initial calling thread until the bitmap is actually available, and then return the generated web site thumbnail. public Bitmap GenerateWebSiteThumbnailImage() { Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage)); m_thread.SetApartmentState(ApartmentState.STA); m_thread.Start(); m_thread.Join(); return m_Bitmap; } The _GenerateWebSiteThumbnailImage will create a WebBrowser control object and navigate to the provided Url. We also register for the DocumentCompleted event of the web browser control to take screen shot of the web page. To pass the flow to the other controls we need to perform a method call to Application.DoEvents(); and wait for the completion of the navigation until the browser state changes to Complete in a loop. private void _GenerateWebSiteThumbnailImage() { WebBrowser m_WebBrowser = new WebBrowser(); m_WebBrowser.ScrollBarsEnabled = false; m_WebBrowser.Navigate(m_Url); m_WebBrowser.DocumentCompleted += new WebBrowserDocument CompletedEventHandler(WebBrowser_DocumentCompleted); while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); m_WebBrowser.Dispose(); } The DocumentCompleted event will be fired when the navigation is completed and the browser is ready for screen shot. We will get screen shot using DrawToBitmap method as described previously which will return the bitmap of the web browser. Then the thumbnail image is generated using GetThumbnailImage method of Bitmap class passing it the required thumbnail image width and height. private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser m_WebBrowser = (WebBrowser)sender; m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight); m_WebBrowser.ScrollBarsEnabled = false; m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height); m_WebBrowser.BringToFront(); m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds); m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero); } One more example here : http://www.codeproject.com/KB/aspnet/Website_URL_Screenshot.aspx

  • C# XNA - Sky Sphere Question

    - by Wade
    I have been banging my head against the wall trying to get a sky sphere to work appropriately in XNA 4.0. I have the sphere loading correctly, and even textured, but i would like something a little more dynamic that can support a day/night cycle. My issue is that, while i know a good amount of C# and XNA, i know next to nothing about HLSL. (I could make an ambient light shader if my life depended on it...) I also have not been able to find a tutorial on how to build a sky sphere like this. Of course i don't expect to be able to make an amazing one right off the bat, i would like to start small, with a dynamic coloring sky i'll work out the clouds and sun later. My first question: Does anyone know of any good tutorial sites that could help me get a decent grasp around HLSL? Second: Does anyone have a good example of or know where to find one of a gradient sky using XNA and C#?

  • Developing for Chrome App/Android?

    - by Johnny Quest
    I have been developing for win7 mobile (XNA/silverlight and will continue to do so, love everything about it) but I wanted to branch a few of my more polished games to google app store online, and perhaps android(though not sure, as with all the different versions it makes learning/loading applications a bit tricky) What is the most versatile language to start learning from chrome apps/android: Java would be excellent for android, but could I port it to a web app for chrome? (and its close to C#) Flash would work for a web app as I can just embed it into a html page (have done actionscript before, didn't care much for the IDE though), but would it also work on android? or I guess there is always C/C++ but haven't heard much about that, though I think it works for both (though C++ does interest me) Any advice would be excellent, thanks.

  • 12.04 boots into terminal after first install. How to boot into GUI permanently?

    - by Deniz
    As a person with a quite limited CLI experience I congratulate myself on installing Ubuntu on an ancient non-pae Fujitsu Amilo M1425 thru the network with mini.iso. However upon reboot I'm met w/ the following: Ubuntu 12.04.1 LTS ubuntu-fujitsu tty1 ubuntu-fujitsu login: for which my specified login during setup is not accepted. (I'm quite sure its correct) Let's assume this screen is passed, how to start the GUI and make it the permanent option during boot? This box will return to a mostly comp-illiterate person, for which the existence of ubuntu will be an enough shock already. Wouldn't wanna leave him w/o the GUI. Other posts here mention the command startx but I probably need a login in the first place.. So "why won't it accept my login & how can I make the GUI-boot permanent?" is my question. Thanks in advance.
