  • Using Dynamic LINQ to get a filter for my Web API

    - by Espo
    We are considering using the Dynamic.CS linq-sample included in the "Samples" directory of visual studio 2008 for our WebAPI project to allow clients to query our data. The interface would be something like this (In addition to the normal GET-methods): public HttpResponseMessage List(string filter = null); The plan is to use the dynamic library to parse the "filter"-variable and then execute the query agains the DB. Any thoughts if this is a good idea? Is it a security problem?

  • Silverlight 3 as a Desktop Application (Out-of-Browser Applications)

    - by kaleidoscope
    A cool new feature in Silverlight 3 is the ability to run Silverlight applications out of the browser which resembles a desktop application. Only a few configuration steps are needed to enable your application to run offline. To enable this feature you only need to open the AppManifest.xml file which can be found in the Properties folder and add some settings as follows: - EntryPointAssembly - EntryPointType - ShortName - Title - Blurb More details can be found at: http://www.silverlightshow.net/items/Silverlight-3-as-a-Desktop-Application-Out-of-Browser-Applications.aspx   Amit, S

  • Is there a driver like this for Windows XP too?

    - by ptikobj
    In Ubuntu, there is a modified non-proprietary Nvidia driver preinstalled. This driver helps me get the full native resolution (1920x1020) of my flatscreen displayed without errors, while my Graphics Card (Geforce FX 5200) only supports DVI-resolutions up to 1440x900. This is a very cool thing. My question is: Is there such a kind of driver also for Windows XP? I've already tried the omega drivers, but 1920x1020 looks awful on Windows.

  • How / Where can I host my Java web application? [closed]

    - by Huliax
    Possible Duplicate: How to find web hosting that meets my requirements? In case you want to skip to the crux of my inquiry just read the bold type. I just finished my CS degree (at 39 years old :-)). For my final project I designed and built a system that can provide local positioning / location awareness to mobile wifi devices (only have Android client thus far). The server receives data from clients, processes it, and responds to the clients with a messages containing information about their respective locations. I would like to continue the project (perhaps release as open source but that is a different discussion). Thus far my server application has been running on the CS department's hardware where I could pretty much do whatever I wanted. I'm getting kicked off that system in a few weeks so I have to find a new home for my server application. I need a host that will let me run my Java server (along w/ mySQL db) -- preferably on the cheap since I haven't yet got a job. I have very little experience with the "real world" of web development / hosting. I'm having trouble figuring out what kind of hosting service will let me run my application as is. If that turns out to be a tall order then I need to know what my options are for changing thing so that I can get up and running with some hosting. As an aside, I'm also researching whether or not I should rewrite this in a different language. Trying to figure out if there is a substantially better (for whatever reason) one for what I'm doing. This might also potentially have a bearing on my hosting needs. One possibility is to write the server in something more widely accepted by hosting services. I have been searching for answers to my question and haven't found quite what I'm looking for. Part of the problem might be that I don't know exactly what terminology to use. If there is a good answer to this question elsewhere please feel free to point me towards it. Thanks for help / advice.

  • Getting started with object detection - Image segmentation algorithm

    - by Dev Kanchen
    Just getting started on a hobby object-detection project. My aim is to understand the underlying algorithms and to this end the overall accuracy of the results is (currently) more important than actual run-time. I'm starting with trying to find a good image segmentation algorithm that provide a good jump-off point for the object detection phase. The target images would be "real-world" scenes. I found two techniques which mirrored my thoughts on how to go about this: Graph-based Image Segmentation: http://www.cs.cornell.edu/~dph/papers/seg-ijcv.pdf Contour and Texture Analysis for Image Segmentation: http://www.eng.utah.edu/~bresee/compvision/files/MalikBLS.pdf The first one was really intuitive to understand and seems simple enough to implement, while the second was closer to my initial thoughts on how to go about this (combine color/intensity and texture information to find regions). But it's an order of magnitude more complex (at least for me). My question is - are there any other algorithms I should be looking at that provide the kind of results that these two, specific papers have arrived at. Are there updated versions of these techniques already floating around. Like I mentioned earlier, the goal is relative accuracy of image segmentation (with an eventual aim to achieve a degree of accuracy of object detection) over runtime, with the algorithm being able to segment an image into "naturally" or perceptually important components, as these two algorithms do (each to varying extents). Thanks! P.S.1: I found these two papers after a couple of days of refining my search terms and learning new ones relevant to the exact kind of techniques I was looking for. :) I have just about reached the end of my personal Google creativity, which is why I am finally here! Thanks for the help. P.S.2: I couldn't find good tags for this question. If some relevant ones exist, @mods please add them. P.S.3: I do not know if this is a better fit for cstheory.stackexchange (or even cs.stackexchange). I looked but cstheory seems more appropriate for intricate algorithmic discussions than a broad question like this. Also, I couldn't find any relevant tags there either! But please do move if appropriate.

  • How do you check out what's hot in the open source space?

    - by Fanatic23
    I am trying to look for resources (sites, magazines, blogs, twitter etc) that track what's hot and happening in the open source space. This is programming language agnostic, I am more interested in knowing what kind of cool apps people are coming up these days particularly in the enterprise and scientific computing space. I am also into compilers, debuggers and other low level stuff. Any help appreciated.

  • Extension methods on a null object instance – something you did not know

    - by nmarun
    Extension methods gave developers with a lot of bandwidth to do interesting (read ‘cool’) things. But there are a couple of things that we need to be aware of while using these extension methods. I have a StringUtil class that defines two extension methods: 1: public static class StringUtils 2: { 3: public static string Left( this string arg, int leftCharCount) 4: { 5: if (arg == null ) 6: { 7: throw new ArgumentNullException( "arg" ); 8: } 9: return arg.Substring(0, leftCharCount); 10...(read more)

  • Speaker Prep Tip: Use the AV Studio Built into that Laptop

    - by merrillaldrich
    Over at erinstellato.com there is a great post this week about tips for new presenters. Ms. Stellato suggests, insightfully, that we record ourselves, which is really a fantastic piece of advice. What’s extra-cool is that today you don’t need any special equipment or expensive software to do just that. This week I “filmed” two run-throughs of my talk for SQL Saturday tomorrow. For me, the timing is the hardest thing – figuring out how much content I can really present in the time allowed without...(read more)

  • Crash when using datablocks

    - by scorcher24
    I have really throughly searched the net and could not find any solution for this so I ask for help here. Anyway, I have this datablock in datablocks.cs: datablock t2dSceneObjectDatablock(EnemyShipConfig) { canSaveDynamicFields = "1"; Layer = "3"; size = "64 64"; CollisionActiveSend = "1"; CollisionActiveReceive = "1"; CollisionCallback = true; CollisionLayers = "3"; CollisionDetectionMode = "POLYGON"; CollisionPolyList = "0.00 -0.791 0.756 0.751 -0.746 0.732"; UsesPhysics = "0"; Rotation = "-90"; WorldLimitMode = "KILL"; WorldLimitMax = "880 360"; WorldLimitMin = "-765 -436"; minFireRate = "2000"; maxFireRate = "1200"; laserSpeed = "800"; minSpeed = "100"; maxSpeed = "150"; }; This is an exact reproduction of an object that I have manually edited in the editor. So far, I just used clone() to get as many enemies as I need, while it was out of sight. It is a r-type style shooter, so I need a variable amount of enemies. Since clone() spams my log, I decided to use datablocks, since it is also more flexible. That's what I get when I use clone(): Con::execute - 0 has no namespace: onRemoveFromScene However, once spawning begins, my game freezes and crashes: function SpawnEnemy() { //%spawnedEnemy = EnemyShipMaster.clone(true); %spawnedEnemy = new t2dStaticSprite() { class = "EnemyShip"; sceneGraph = $global_sceneGraph; datablock = "EnemyShipConfig"; imageMap = "starshipImageMap"; layer = 3; }; %speed = getRandom(%spawnedEnemy.minSpeed, %spawnedEnemy.maxSpeed); %y = getRandom(-320, 320); // Set Properties %spawnedEnemy.setPositionX(700); %spawnedEnemy.setPositionY(%y); %spawnedEnemy.setVisible(true); %spawnedEnemy.setLinearVelocityX( -%speed ); %spawnedEnemy.setTimerOn( getRandom( %spawnedEnemy.maxFireRate, %spawnedEnemy.minFireRate ) ); } // Definition of $global_sceneGraph from game.cs: $global_sceneGraph = sceneWindow2D.loadLevel(%level); As I said, it works fine when I use clone() (which is commented out here), but my log gets spammed. I really hope someone can shed some light for me, this is driving me crazy.

  • What program has this icon?

    - by Andrew M
    I noticed a screenshot that included this icon in the sidebar, does anyone know what it's from? It looks cool! Looks vaguely reminiscient of Chrome but different enough that it could be a coincidence. I've tried putting it into a google image search but without any luck. Original source was this Ubuntu help page on unity launchers. which includes the original, larger screenshot. For context, it's not important, I'm just curious.

  • Uniform url in different device

    - by yanglifu90
    I noticed almost all of StackExchange's sites uses the same url in mobile browser, I think this is cool because when I share something on my phone, people viewing the link would not see a mobile webpage on their desktop. What is this specification called by W3C? How do I find other websites that use this technology. I noticed that ArsTechnica and the Telegraph used the same url with their desktop version.

  • Damageable ground similar to pocket tanks or archanists [closed]

    - by XenElement
    Possible Duplicate: Implementing a 2D destructible landscape (like Worms) A really cool feature in both the iPhone game pocket tanks and the online jagex game archanists is ground which can be blown up. When a projectile collides with the ground, an area equal to the blast radius which overlaps the ground is removed. It's strictly two dimensional, but it makes the experience that much more dynamic since you can dig a hole under your opponents or yourself. How is this implemented?

  • Recommended readings for a sofware construction mini-course [on hold]

    - by Aivar
    I'm going to organize a mini-course for CS students who have completed CS1 (Python) and CS2 (Java). I'd like to show them more principled approach to programming practice and design, something along the lines of McConnel's Code Complete. If I had enough copies of Code Complete, I would assign some readings from that book. Can you recommend some freely available material (books, blog posts, articles, essays) for such a course? (I'd prefer to avoid topics specific to OOP and focus on more universal principles.)

  • Hows to set Skype shortcut for opening existing instance?

    - by Koffeehaus
    I'm using Linux for about two years now, but due to my Windows legacy I like keeping shortcuts on my desktop instead of dockies, panel shortcuts, etc. If Skype is already running, pressing the shortcut starts a new sequence rather than opening an existing one. This is kinda cool as you can have two accounts running. But I only have one. So, my question is whether it is possible to tweak Skype into opening an already existent instance when pressing the shortcut?

  • What are some of the more commonly used projectile rendering techniques?

    - by KlashnikovKid
    couldn't find a duplicate question (bit surprising to me) but anywho I'm starting to get near implementing the rendering of projectiles for my game. My question is what are some good techniques for efficiently rendering projectiles? I would like emphasis on techniques that leave room for the projectiles to be "rich" and dynamic (Cool to look at!) I'm also using DX11 for my rendering engine so bleeding edge techniques that can make use of that would be much appreciated too. Thanks!

  • Do first-class methods exist?

    - by gdhoward
    Okay, I know first-class functions are cool, closures even better, etc. But is there any language with first-class methods? In my mind, I see a first-class method as an "object" that has both a function pointer and a pointer to a specific instance of the class/object, but the implementation doesn't matter. I just want to know if there is any language that uses them. And as a bonus, how were they implemented?
