  • Finetuning movement based on gradual rotation towards a target

    - by A.B.
    I have an object which moves towards a target destination by gradually adjusting its facing while moving forwards. If the target destination is in a "blind spot", then the object is incapable of reaching it. This problem is ilustrated in the picture below. When the arrow is ordered to move to point A, it will only end up circling around it (following the red circle) because it is not able to adjust its rotation quickly enough. I'm interested in a solution where the movement speed is multiplied by a number from 0.1 to 1 in proportion to necessity. The problem is, how do I calculate whether it is necessary in the first place? How do I calculate an appropriate multiplier that is neither too small nor too large? void moveToPoint(sf::Vector2f destination) { if (destination == position) return; auto movement_distance = distanceBetweenPoints(position, destination); desired_rotation = angleBetweenPoints(position, destination); /// Check whether rotation should be adjusted if (rotation != desired_rotation) { /// Check whether the object can achieve the desired rotation within the next adjustment of its rotation if (Radian::isWithinDistance(rotation, desired_rotation, rotation_speed)) { rotation = desired_rotation; } else { /// Determine whether to increment or decrement rotation in order to achieve desired rotation if (Radian::convert(desired_rotation - rotation) > 0) { /// Increment rotation rotation += rotation_speed; } else { /// Decrement rotation rotation -= rotation_speed; } } } if (movement_distance < movement_speed) { position = destination; } else { position.x = position.x + movement_speed*cos(rotation); position.y = position.y + movement_speed*sin(rotation); } updateGraphics(); }

  • Ghost Incognito Automatically Loads Incognito Mode Based on Domain

    - by Jason Fitzpatrick
    Chrome: Ghost Incognito mode is a simple Chrome extension that automatically launches Incognito mode on a domain-by-domain basis. If you routinely visit the same sites using Incognito Mode, Ghost Incognito allows you to flag domains. By default it turns on Incognito for all .XXX domains and, once you select some domains, for any that you specify. Thus if you flag angrybirds.com, as we did for our test run of the app, every time you visit angrybirds.com or a sub-domain there of such as shop.angrybirds.com, you’ll be automatically directed to a new Incognito tab–no input from you necessary.

  • Game based on Ajax polling for 12 players

    - by Azincourt
    I am planning on writing a small browser game. The webserver is a shared server, with no root / install possible. I want to use AJAX for client/server communication. There will be 12 players. So each player would be polling the server for the current game status every X milliseconds (let's say 200ms). So that would be 200ms x 12 players x 5 = 60 requests per second Can Apache handle those requests? What might be the bottlenecks when using this attempt?

  • Oracle’s New Approach to Cloud-based Applications User Experiences

    - by Oracle OpenWorld Blog Team
    By Misha Vaughan It was an exciting Oracle OpenWorld this year for customers and partners, as they got to see what their input into the Oracle user experience research and development process has produced for cloud-delivered applications. The result of all this engagement and listening is a focus on simplicity, mobility, and extensibility. These were the core themes across Oracle OpenWorld sessions, executive roundtables, and analyst briefings given by Jeremy Ashley, Oracle's vice president of user experience. The highlight of every meeting with a customer featured the new simplified UI for Oracle’s cloud applications.    Attendees at some sessions and events also saw a vision of what is coming next in the Oracle user experience, and they gave direct feedback on whether this would help solve their business problems.  What did attendees think of what they saw this year? Rebecca Wettemann of Nucleus Research was part of  an analyst briefing on next-generation user experiences from Oracle. Here’s what she told CRM Buyer in an interview just after the event:  “Many of the improvements are incremental, which is not surprising, as Oracle regularly updates its application,” Rebecca Wettemann, vice president of Nucleus Research, told CRM Buyer. "Still, there are distinct themes to this latest set of changes. One is usability. Oracle Sales Cloud, for example, is designed to have zero training for onboarding sales reps, which it does," she explained. "It is quite impressive, actually—the intuitive nature of the application and the design work they have done with this goal in mind. The software uses as few buttons and fields as possible," she pointed out. "The sales rep doesn't have to ask, 'what is the next step?' because she can see what it is."  What else did we hear? Oracle OpenWorld is a time when we can take a broader pulse of our customers’ and partners’ concerns. This year we heard some common user experience themes on the following: · A desire to continue to simplify widely used self-service tasks · A need to understand how customers or partners could take some of the UX lessons learned on simplicity and mobility into their own custom areas and projects  · The continuing challenge of needing to support bring-your-own-device and corporate-provided mobile devices to end users · A desire to harmonize user experiences across platforms for specific business-use cases  What does this mean for next year? Well, there were a lot of things we could only show to smaller groups of customers in our Oracle OpenWorld usability labs and HQ lab tours, to partners at our Expo, and to analysts under non-disclosure agreements. But we used these events as a way to get some early feedback about where we are focusing for the year ahead. Attendees gave us a positive response: @bkhan Saw some excellent UX innovations at the expo “@usableapps: Great job @mishavaughan and @vinoskey on #oow13 UX partner expo!” @WarnerTim @usableapps @mishavaughan @vinoskey @ultan Thanks for an interesting afternoon definitely liked the UX tool kits for partners. You can expect Oracle to continue pushing themes of simplicity, mobility, and extensibility even more aggressively in the next year.  If you are interested to find out what really goes on in the UX labs, such as what we are doing with smartphones, tablets, heads-up displays, and the AppsLab robots, feel free to reach out to me for more information: Misha Vaughan or on Twitter: @mishavaughan.

  • C++ Game Library for SVG Based Game

    - by lefticus
    I'm looking into building a cross-platform opensource 2D RPG style game engine for ChaiScript. I want to be able to do all of the graphics with SVG and need joystick input. I also need the libraries I use to be opensource and compatible with the BSD license. I'm familiar with allegro, ClanLib, and SDL. As far as I can tell, none of these libraries have built in or obvious integration for SVG. Also, I'm aware of the previous conversations on this site regarding Qt for SVG game development. I'm hoping to avoid Qt because of the size and complexity of making it a requirement. Also, Qt does not seem to have joystick input support, which would require that SDL or some other library also be used. So my question can be summed up as this: What is the best way to get SVG and joystick support in a 2D C++ library while minimizing dependencies as much as possible (preferably avoiding Qt altogether)?

  • Do keyword-based filenames and URLs really matter?

    - by Justin Scott
    We've developed a dynamic web application which uses URLs such as product.cfm?id=42 but our marketing team says we should use search friendly URLs and put our keywords into the URLs (so it would be product-name.cfm instead). Our developers tell us this will cost more money and take additional time. Is it worth the effort? How important is this to the search engines and will it impact our rankings?

  • How to perform regular expression based replacements on files with MSBuild

    - by Daniel Cazzulino
    And without a custom DLL with a task, too . The example at the bottom of the MSDN page on MSBuild Inline Tasks already provides pretty much all you need for that with a TokenReplace task that receives a file path, a token and a replacement and uses string.Replace with that. Similar in spirit but way more useful in its implementation is the RegexTransform in NuGet’s Build.tasks. It’s much better not only because it supports full regular expressions, but also because it receives items, which makes it very amenable to batching (applying the transforms to multiple items). You can read about how to use it for updating assemblies with a version number, for example. I recently had a need to also supply RegexOptions to the task so I extended the metadata and a little bit of the inline task so that it can parse the optional flags. So when using the task, I can pass the flags as item metadata as follows:...Read full article

  • Audiencing with Forms-Based Authentication (FBA)

    - by PeterBrunone
    This really is no different from when you create an audience with regular old NTLM (Windows Authentication).  The difference is that while the AD provider is set up by default in all environments, the extra membership provider (that you use for Forms Authentication) isn't included anywhere except in the web application where you install it.  To be able to find your FBA users in the audience creation tool, you'll need to add the extra membership provider(s) to the web.config for your SSP site in IIS.  At that point, the People Picker should start recognizing your Forms Auth users, and you can create your audience as needed.

  • Git-based storage and publishing, infrastructure advice

    - by Joel Martinez
    I wanted to get some advice on moving a system to "the cloud" ... specifically, I'm looking to move into some of Windows Azure's managed services, as right now I'm managing a VM. Basically, the system operates on some data stored in a github git repository. I'll describe the current architecture: Current system (all hosted on a single server): GitHub - configured with a webhook pointing at ... ASP.NET MVC application - to accept the webhook from git. It pushes a message onto ... Azure service bus Queue - which is drained by ... Windows Service - pulls the message from the queue and ... Fetches the latest data from the git repository (using GitLib2Sharp) onto the local disk and finally ... Operates on the data in git to produce a static HTML website hosted/served by IIS. The system works really well, actually ... but I would like to get out of the business of managing the VM, and move to using some combination of Azure web and worker roles. But because the system relies so heavily on the git repository on the local filesystem, I'm finding it difficult to figure out how to architect in the cloud. I know you can get file system access, so in theory I could just fetch the repository if there's nothing on disk ... but the performance/responsiveness of the system sort of depends on the repository being available and only having to fetch diffs, which is relatively quick. As opposed to periodically having to fetch the entire (somewhat large) git repository if the web or worker role was recycled, or something. So I would love some advice on how you would architect such a system :) Ultimately, the only real requirement is to be able to serve HTML content that's been produced from the contents of a git repository (in a relatively responsive manner, from a publishing perspective) ... please feel free to ask any clarifying questions if there's something I omitted. Thanks!

  • Good Atom Based Tablets that run Ubuntu?

    - by Anthony Papillion
    I'm starting a software project for a company that will deploy on tablet computers. They want to stick with Intel processors so they are looking for a good tablet that runs on an Atom processor. MY requirement is that it needs to also be able to run Ubuntu. It doesn't have to come with Ubuntu, I just need to be able to install it with no hassle. But, if it comes with Ubuntu preinstalled, that's even better. Can anyone make a recommend? Thanks! Anthony

  • per pixel based collision detection.

    - by pengume
    I was wondering if anyone had any ideas on how to get per pixel collision detection for the android. I saw that the andEngine has great collision detection on rotation as well but couldn't see where the actual detection happened per pixel. Also noticed a couple solutions for java, could these be replicated for use with the Android SDK? Maybe someone here has a clean piece of code I could look at to help understand what is going on with per pixel detection and also why when rotating it is a different process.

  • Voice echo in UDP based voice transmission [closed]

    I have coded a java application for voice transmission between to ip in LAN. Here the code. public static Boolean flag= true; public static Boolean recFlag=true; DatagramSocket UDPSocket=null; AudioFormat format = null; TargetDataLine microphone=null; byte[] buffer=null; DatagramPacket UDPPacket=null; public void startChat(String ipAddress){ try{ buffer = new byte[1000]; UDPSocket=new DatagramSocket(1987); Thread th=new Thread(new Listener()); th.start(); microphone = AudioSystem.getTargetDataLine(format); format= new AudioFormat(8000.0f, 16, 1, true, true); UDPPacket = new DatagramPacket(buffer, buffer.length, InetAddress.getByName(ipAddress), 1988); microphone.open(format); microphone.start(); while (flag) { microphone.read(buffer, 0, buffer.length); UDPSocket.send(UDPPacket); } } catch(Exception e){ System.out.println(" ssss "+e.getMessage()); } } public class Listener extends Thread{ byte[] buff=new byte[1000]; DatagramSocket UDPSocket1=null; DatagramPacket recPacket=null; DataLine.Info info = new DataLine.Info(SourceDataLine.class, format); SourceDataLine line=null; @Override public void run(){ try{ UDPSocket1=new DatagramSocket(1988); format= new AudioFormat(8000.0f, 16, 1, true, true); line = (SourceDataLine) AudioSystem.getLine(info); line.open(format); line.start(); } catch(Exception e){ System.out.println("list "+ e.getMessage()); } recPacket=new DatagramPacket(buff, buff.length); while(recFlag){ try{ UDPSocket1.receive(recPacket); buff = (byte[])recPacket.getData(); line.write(buff, 0, buff.length); } catch(Exception e){ System.out.println("errr "+e.getMessage()); } } line.drain(); line.close(); } } Main problem which I am facing that I am getting only echo of my own voice. I am unable to hear voice from the other end only I am hearing is my own voice. Please suggest any solution.

  • C# wpf helix scale based mesh parenting using Transform3DGroup

    - by Rick2047
    I am using https://helixtoolkit.codeplex.com/ as a 3D framework. I want to move black mesh relative to the green mesh as shown in the attached image below. I want to make green mesh parent to the black mesh as the change in scale of the green mesh also will result in motion of the black mesh. It could be partial parenting or may be more. I need 3D rotation and 3D transition + transition along green mesh's length axis for the black mesh relative to the green mesh itself. Suppose a variable green_mesh_scale causing scale for the green mesh along its length axis. The black mesh will use that variable in order to move along green mesh's length axis. How to go about it. I've done as follows: GeometryModel3D GreenMesh, BlackMesh; ... double green_mesh_scale = e.NewValue; Transform3DGroup forGreen = new Transform3DGroup(); Transform3DGroup forBlack = new Transform3DGroup(); forGreen.Children.Add(new ScaleTransform3D(new Vector3D(1, green_mesh_scale , 1))); // ... transforms for rotation n transition GreenMesh.Transform = forGreen ; forBlack = forGreen; forBlack.Children.Add(new TranslateTransform3D(new Vector3D(0, green_mesh_scale, 0))); BlackMesh.Transform = forBlack; The problem with this is the scale transform will also be applied to the black mesh. I think i just need to avoid the scale part. I tried keeping all the transforms but scale, on another Transform3DGroup variable but that also not behaving as expected. Can MatrixTransform3D be used here some how? Also please suggest if this question can be posted somewhere else in stackexchange.

  • What happened to VM based deployments?

    - by user128670
    Watched some MountainWest RubyConf 2014 talks and noticed an interesting theme. Many dynamic programming environments back in the old days used to be self-contained VM images, e.g. SmallTalk, GemStone/S. One could checkpoint, modify, and ship these images wholesale and have it up and running with very little effort. Fast forward to now and I'm still using Make files to configure and install binaries. What happened?
