  • Detecting right-click on XAML GridView control item

    - by mbrit
    Leaving aside why you would ever want to do this in a touch-centric world, here's how you tell if the right-mouse button has been clicked on a GridView in XAML/WinRT/Metro-style. You have to retrieve a point relative to the UI element you're in, and then query its properties. void itemGridView_PointerPressed(object sender, PointerRoutedEventArgs e) { if (e.GetCurrentPoint(this).Properties.IsRightButtonPressed) { this.BottomAppBar.IsOpen = true; } } (The reason why you might want to do this can be explained by looking at any of the built-in Win8 apps. You can right-click any of the items on any list to bring up a context-sensitive AppBar.)

  • Top Down bounds of vision

    - by Rorrik
    Obviously in a first person view point the player sees only what's in front of them (with the exception of radars and rearview mirrors, etc). My game has a top down perspective, but I still want to limit what the character sees based on their facing. I've already worked out having objects obstruct vision, but there are two other factors that I worry would be disorienting and want to do right. I want the player to have reduced peripheral vision and very little view behind them. The assumption is he can turn his head and so see fairly well out to the sides, but hardly at all behind without turning the whole body. How do I make it clear you are not seeing behind you? I want the map to turn so the player is always facing up. Part of the game is to experience kind of a maze and the player should be able to lose track of North. How can I turn the map rather than the player avatar without causing confusion?

  • Enabling and Disabling components in Unity

    - by Blue
    I'm trying to create an enable/ disable game objects in Unity. I used GameObject.SetActiveRecursively but it only works one-way. I used a collider in which when an object enters the collider. The game objects become enabled. When they leave or get to a certain point, they disable. How would I make this a two way system, making it able to be enabled while inside the collider and disabled when outside the collider? -- The collider is in the game object who is being disabled and enabled. According to this information from Unity Answers, the object becomes disabled. So how would I make the object enabled?

  • Auto mount USB drive with permissions for all users

    - by oneaustin
    I have an Ubuntu 14.04 based Media Center and I store the media files on a USB HDD. I add files to drive directly on a Mac so I have it formatted as FAT32. The problem is that after reconnecting the drive to the Ubuntu, it mounts at /media/user/drivename and only the root user is allowed access. I need several applications to have full access to this drive. I can change file permissions in the terminal but it doesn't change because of the /media/user location. I am able to manually sudo mount /dev/sdc1 /media/drivename & sudo chmod 777 /media/drivename but the mount point changes each time. Is there a way to make this drive always mount where root and other applications have access?

  • Credit Card Payment Processing which APIs do you use?

    - by user3330840
    It's for a Point of Sale Terminal where the customer will bring the physical credit card and it will be swiped through the terminal. The business has a merchant account on some banks. So, how do I start accepting credit cards in my app? The credit cards that needs to be accepted include: visa, master-card, amex, discover. Which APIs do I need to use? The programming language doesn't matter it can be in any programming languages Java/C#/C++/Python or anything. Will there be a single API or multiple APIs that need to be integrated? (I know some about PCI compliance and security encryption)

  • Sense of "stop on..." stanza when job is a task

    - by Binarus
    Hi, an upstart question (I think I have read all relevant man pages but could not find the answer there): What is the sense of using a "stop on ..." stanza in the definition of a job which is a task? The manuals tell us that such a job, after being started, just waits until its script (or exec stanza) is executed completely, and then stops automatically. Given that, what is the point in using "stop on ..." stanzas in such job definitions? For example, this is the job definition for Upstart's (very important) rc job in Natty 11.04 (leaving out comments and empty lines): start on runlevel [0123456] stop on runlevel [!$RUNLEVEL] export RUNLEVEL export PREVLEVEL console output env INIT_VERBOSE task exec /etc/init.d/rc $RUNLEVEL IMHO, the job, after being started by a runlevel event, will be stopped automatically as soon as /etc/init.d/rc $RUNLEVEL has finished. Thank you very much for any explanation!

  • How to structure an application which reads UPC barcodes

    - by tugberk
    I have no previous experience on creating a project for a seller which will use barcode reader. I am trying to put together a small project but I cannot figure out how the pieces should glue together. I will create a sample with Motorola Scanner SDK to read barcodes and from that point, I have couple of questions: How UPC barcodes work in general? AFAIK, a barcode stores the manufacturer and product info but no price data. Should I store price information inside a database which corresponds to barcode data? I would really appreciate if you can guide me here.

  • What are some concise and comprehensive introductory guide to unit testing for a self-taught programmer [closed]

    - by Superbest
    I don't have much formal training in programming and I have learned most things by looking up solutions on the internet to practical problems I have. There are some areas which I think would be valuable to learn, but which ended up both being difficult to learn and easy to avoid learning for a self-taught programmer. Unit testing is one of them. Specifically, I am interested in tests in and for C#/.NET applications using Microsoft.VisualStudio.TestTools in Visual Studio 2010 and/or 2012, but I really want a good introduction to the principles so language and IDE shouldn't matter much. At this time I'm interested in relatively trivial tests for small or medium sized programs (development time of weeks or months and mostly just myself developing). I don't necessarily intend to do test-driven development (I am aware that some say unit testing alone is supposed to be for developing features in TDD, and not an assurance that there are no bugs in the software, but unit testing is often the only kind of testing for which I have resources). I have found this tutorial which I feel gave me a decent idea of what unit tests and TDD looks like, but in trying to apply these ideas to my own projects, I often get confused by questions I can't answer and don't know how to answer, such as: What parts of my application and what sorts of things aren't necessarily worth testing? How fine grained should my tests be? Should they test every method and property separately, or work with a larger scope? What is a good naming convention for test methods? (since apparently the name of the method is the only way I will be able to tell from a glance at the test results table what works in my program and what doesn't) Is it bad to have many asserts in one test method? Since apparently VS2012 reports only that "an Assert.IsTrue failed within method MyTestMethod", and if MyTestMethod has 10 Assert.IsTrue statements, it will be irritating to figure out why a test is failing. If a lot of the functionality deals with writing and reading data to/from the disk in a not-exactly trivial fashion, how do I test that? If I provide a bunch of files as input by placing them in the program's directory, do I have to copy those files to the test project's bin/Debug folder now? If my program works with a large body of data and execution takes minutes or more, should my tests have it do the whole use all of the real data, a subset of it, or simulated data? If latter, how do I decide on the subset or how to simulate? Closely related to the previous point, if a class is such that its main operation happens in a state that is arrived to by the program after some involved operations (say, a class makes calculations on data derived from a few thousands of lines of code analyzing some raw data) how do I test just that class without inevitably ending up testing that class and all the other code that brings it to that state along with it? In general, what kind of approach should I use for test initialization? (hopefully that is the correct term, I mean preparing classes for testing by filling them in with appropriate data) How do I deal with private members? Do I just suck it up and assume that "not public = shouldn't be tested"? I have seen people suggest using private accessors and reflection, but these feel like clumsy and unsuited for regular use. Are these even good ideas? Is there anything like design patterns concerning testing specifically? I guess the main themes in what I'd like to learn more about are, (1) what are the overarching principles that should be followed (or at least considered) in every testing effort and (2) what are popular rules of thumb for writing tests. For example, at one point I recall hearing from someone that if a method is longer than 200 lines, it should be refactored - not a universally correct rule, but it has been quite helpful since I'd otherwise happily put hundreds of lines in single methods and then wonder why my code is so hard to read. Similarly I've found ReSharpers suggestions on member naming style and other things to be quite helpful in keeping my codebases sane. I see many resources both online and in print that talk about testing in the context of large applications (years of work, 10s of people or more). However, because I've never worked on such large projects, this context is very unfamiliar to me and makes the material difficult to follow and relate to my real world problems. Speaking of software development in general, advice given with the assumptions of large projects isn't always straightforward to apply to my own, smaller endeavors. Summary So my question is: What are some resources to learn about unit testing, for a hobbyist, self-taught programmer without much formal training? Ideally, I'm looking for a short and simple "bible of unit testing" which I can commit to memory, and then apply systematically by repeatedly asking myself "is this test following the bible of testing closely enough?" and then amending discrepancies if it doesn't.

  • Maven Command Line for NetBeans RCP Developers

    - by Geertjan
    In the ongoing work being done on Maven documentation support for NetBeans Platform developers, the tutorial describing how to use the Maven command line to set up and develop applications on the NetBeans Platform has ben updated: http://platform.netbeans.org/tutorials/nbm-maven-commandline.html An interesting next step after following the tutorial above is to... open the result into the free community edition of IntelliJ IDEA: It's not hard to register the JDK and Maven in IntelliJ IDEA and to then run your application directly from there. The point is that there's no requirement to use NetBeans IDE if you want to create applications on top of its framework.

  • No analog audio in 13.10

    - by danepowell
    I've installed 13.10 on a machine that was previously running Windows 8, and audio output isn't working out of the box. It worked fine in Windows, and the speakers work fine when hooked up to a laptop, so it must an incompatibility between Ubuntu and the motherboard. If I go to sound settings, "Built-in Audio" is selected (SPDIF is also available). This is an Intel Z77 motherboard with an integrated Creative CA0132 sound chipset. I've tried booting a live image of 13.10 (to check for a corrupt install), and the same problem exists. If I boot a live image of 13.04, the only audio output listed in sound settings is a "dummy" card. I've already tried basic troubleshooting steps, such as removing pulseaudio config directories, force-restarting alsa, and making sure the speakers aren't muted in the alsa mixer. At this point, I'm totally stumped :(

  • Still no wireless after b43 with Dell Inspiron 1525 (Ubuntu 12.04)

    - by DanielleN
    So I followed the instructions here http://ubuntuforums.org/showthread.php?t=1974006 about how to solve this issue. It worked for a bit and then stopped. After doing a modprobe I could at least see my network and click on it but it would not connect (I can always see it if I look under the listed wireless networks under VPN Connections, however). I'm thinking, from what I read at least, the issue might be that my wireless switch was on during those first steps. Do I now have to undo the b43 install and do it again? Or is there something else I could try? I just made the switch to Linux yesterday, so I am hesitant at this point to mess with anything on my own. I should note now that it was installed by someone who knows what they are doing, so we are all good on that front.

  • Game Development Resources? [closed]

    - by stas
    I want to make an iPhone game and I was wondering if somebody could point me to some resources. Before you rage and close this, I am not looking for just a tutorial on programming, I could just google that. I need to find a tutorial on how to actually make a game, as in how to organize your code, what type of methods to run in separate threads, how to manage these threads in a game, etc. I already know everything I need; I can write a physics engine from scratch, I can write a 3D graphics pipeline from scratch, and so on. What I cannot figure out is how to combine all of this knowledge into correctly and efficiently making a game. Obviously for this one would probably go to college, but seeing as I am still in high school, that is not an option. If anyone would know some tutorials or resources, any pointers would be appreciated.

  • Massive vehicular network simulator

    - by IvanK
    I am interested in making a vehicular network simulator (vehicular network as in vehicles can be equipped with radios and when they come in range they can talk with each other). I want to be able to scale to 1000s of nodes if not more. I am quite frankly torn on how to do, or even which language to use or whether I should instead be using some other piece of software/code. I know that this should depend on a lot of design decisions that I may have, but it would be great if somebody can point me towards the right direction. I was planning to use a multi-threaded architecture, but not sure whether it will add to the complication or make it easier. Also if I go for a multi-threaded architecutre, do you think that 'Go' language will be a good choice?

  • SharePoint 2010: Architecture and Planning information

    - by Enrique Lima
    Recently I have been delivering Design and Planning Sessions at client sites, and as of recent SharePoint 2010 has been part of that mix. After the activity that goes on during those sessions getting towards the end of them is always a cross roads for clients.  Why?  Because it is time to kick the wheels.  Remind them, and remember, this is not a 1 or 4 weeks ordeal.  This has to be very well planned. If I am looking for information that is worth while and a great conversation starter, my landing point is the TechNet Library.  Here is focus on the Planning and Architecture documentation.  There are some great pieces of info, and a great set of planning worksheets. Here is the link to this section … http://technet.microsoft.com/en-us/library/cc261834.aspx

  • Different set of workspaces for each monitor? Ubuntu 13.04 with Unity

    - by Darren
    currently for my new setup, I have a 3 monitor setup. With an NVIDIA Geforce GTX 770(if this matters for this). What I'm wanting to do, is to create a separate set of workspaces for each monitor. For instance: Monitor 1 has a set of 4 workspaces, that are specific to monitor 1, and change independently of the other monitors. Then the other 2 monitors also have their own set of 4 workspaces. So in total I would have 12 workspaces, but each monitor would have it's own set of 4 that work independently from the others. I've read things about Xmonad and Xinerama, but I'm not really sure where to go from here. I haven't ventured to far into different window managers and everything. I'm sure there's not a tool that does this, but if someone could point me in the right direction(I've been using Ubuntu for about 4 years so I can figure some things out on my own too).

    Windows Communication Foundation 4 - ISBN 978-0-7356-4556-1 is one of the Microsoft Step-By-Step books. I will be studying this book over the comming weeks. What I have seen so far impresses me. One very practical item that more books of the type should have was the "Finding your best starting point". There is one feature about this book that I hope Microsoft Press will provide on more books and that is to also provide the book electronically via Safari. Included in this is getting the book as a PDF!

  • Gnome/X logs off immediately after login -- which logfiles are relevant?

    - by joebuntu
    I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken?

  • How do you deal with transitions in animating walking?

    - by Aerovistae
    I'm pretty new to this whole animating models thing. Just learning the ropes. I got a nice walking animation going, which I can loop while a character is walking, but what about when they stop walking? I mean, they could be at any point in the animation at the time the player stops walking. How do I get them to smoothly return to a standing still position without having them snap into that position? The same goes for starting walking from a standing still position. Do you need a separate animation? How is this dealt with?

  • Using Subjects to Deploy Queries Dynamically

    - by Roman Schindlauer
    In the previous blog posting, we showed how to construct and deploy query fragments to a StreamInsight server, and how to re-use them later. In today’s posting we’ll integrate this pattern into a method of dynamically composing a new query with an existing one. The construct that enables this scenario in StreamInsight V2.1 is a Subject. A Subject lets me create a junction element in an existing query that I can tap into while the query is running. To set this up as an end-to-end example, let’s first define a stream simulator as our data source: var generator = myApp.DefineObservable(     (TimeSpan t) => Observable.Interval(t).Select(_ => new SourcePayload())); This ‘generator’ produces a new instance of SourcePayload with a period of t (system time) as an IObservable. SourcePayload happens to have a property of type double as its payload data. Let’s also define a sink for our example—an IObserver of double values that writes to the console: var console = myApp.DefineObserver(     (string label) => Observer.Create<double>(e => Console.WriteLine("{0}: {1}", label, e)))     .Deploy("ConsoleSink"); The observer takes a string as parameter which is used as a label on the console, so that we can distinguish the output of different sink instances. Note that we also deploy this observer, so that we can retrieve it later from the server from a different process. Remember how we defined the aggregation as an IQStreamable function in the previous article? We will use that as well: var avg = myApp     .DefineStreamable((IQStreamable<SourcePayload> s, TimeSpan w) =>         from win in s.TumblingWindow(w)         select win.Avg(e => e.Value))     .Deploy("AverageQuery"); Then we define the Subject, which acts as an observable sequence as well as an observer. Thus, we can feed a single source into the Subject and have multiple consumers—that can come and go at runtime—on the other side: var subject = myApp.CreateSubject("Subject", () => new Subject<SourcePayload>()); Subject are always deployed automatically. Their name is used to retrieve them from a (potentially) different process (see below). Note that the Subject as we defined it here doesn’t know anything about temporal streams. It is merely a sequence of SourcePayloads, without any notion of StreamInsight point events or CTIs. So in order to compose a temporal query on top of the Subject, we need to 'promote' the sequence of SourcePayloads into an IQStreamable of point events, including CTIs: var stream = subject.ToPointStreamable(     e => PointEvent.CreateInsert<SourcePayload>(e.Timestamp, e),     AdvanceTimeSettings.StrictlyIncreasingStartTime); In a later posting we will show how to use Subjects that have more awareness of time and can be used as a junction between QStreamables instead of IQbservables. Having turned the Subject into a temporal stream, we can now define the aggregate on this stream. We will use the IQStreamable entity avg that we defined above: var longAverages = avg(stream, TimeSpan.FromSeconds(5)); In order to run the query, we need to bind it to a sink, and bind the subject to the source: var standardQuery = longAverages     .Bind(console("5sec average"))     .With(generator(TimeSpan.FromMilliseconds(300)).Bind(subject)); Lastly, we start the process: standardQuery.Run("StandardProcess"); Now we have a simple query running end-to-end, producing results. What follows next is the crucial part of tapping into the Subject and adding another query that runs in parallel, using the same query definition (the “AverageQuery”) but with a different window length. We are assuming that we connected to the same StreamInsight server from a different process or even client, and thus have to retrieve the previously deployed entities through their names: // simulate the addition of a 'fast' query from a separate server connection, // by retrieving the aggregation query fragment // (instead of simply using the 'avg' object) var averageQuery = myApp     .GetStreamable<IQStreamable<SourcePayload>, TimeSpan, double>("AverageQuery"); // retrieve the input sequence as a subject var inputSequence = myApp     .GetSubject<SourcePayload, SourcePayload>("Subject"); // retrieve the registered sink var sink = myApp.GetObserver<string, double>("ConsoleSink"); // turn the sequence into a temporal stream var stream2 = inputSequence.ToPointStreamable(     e => PointEvent.CreateInsert<SourcePayload>(e.Timestamp, e),     AdvanceTimeSettings.StrictlyIncreasingStartTime); // apply the query, now with a different window length var shortAverages = averageQuery(stream2, TimeSpan.FromSeconds(1)); // bind new sink to query and run it var fastQuery = shortAverages     .Bind(sink("1sec average"))     .Run("FastProcess"); The attached solution demonstrates the sample end-to-end. Regards, The StreamInsight Team

  • Easiest Way to Get Started With 3D?

    - by ryebread761
    I'm looking at getting into 3D game development and am wondering what would be the best, quickest engine to get started with. I need to be able to develop on a Macintosh with it. I know Java, and PHP mainly but have worked in many others. At this point, I feel I can adapt to most languages quite easy. So the programming language doesn't really matter to me. I've sorta kinda tried unity in the past and wasn't all too fond of it, so it's kind of a "I can't find anything better" resort. I'm hoping with how open I am I will find something I like more. Thanks in advance.

  • Online Syntax Colorizer

    - by lavanyadeepak
    Online Syntax Colorizer For those of us who share code snippets along with articles the most daunting problem would be to preserve the syntax colorizations. There are a few ways to manage through this additional requirements: Tweak and point the color picker in the article textearea. Import the code to a word processor and then copy the code. However, the word processor would unnecessarily swell the contents with too much of formatting contents. Quick Online Colorizer: http://tohtml.com/ (This supports a lot of languages including autodetection). I would also recommend if GWB could link to this website and auto-colorize the code when we paste it in our articles.
