  • Silverlight penetration rate

    - by sthg
    Duplicate of: Silverlight Install Base - How big is it? Hi, Anyone knows the penetration rate (in %) for all North-American internet users with the Silverlight plugin installed? Been looking all around, but couldn't find any comprehensive numbers. I'm looking for General Public penetration rates, not only within the dev community. Something close to Adobe's flash version penetration stats would be great.

  • Which is clearer form: if(!value) or if(flag == value) ?

    - by CodexArcanum
    I understand this is a subjective question, so I apologize if it needs to be closed, but I feel like it comes up often enough for me to wonder if there is a general preference for one form over the other. Obviously, the best answer is "refactor the code so you don't need to test for falsehood" but sometimes there's no easy way to do so and the "else" branch is simply to continue processing. So when you must have an "if not false" construct, which is the preferred standard: The not operator if(!value) Or the test for false if(value == false)

  • What is the best way to organize object oriented code?

    - by Adam
    I haven't coded in java for a long time, and after coding in C, I'm having issued organizing my code for OOP. More specifically I'm not sure when to create a new method, and when to create a new class, and when to just lump everything together. Are there some general rules or guidelines on how it should be done?

  • REST verbs - which convention is "correct"

    - by ctacke
    I'm well into implementing a REST service (on a Windows CE platform if that matters) and I started out using IBM's general definitions of using POST for creating (INSERTs) and PUT for updating. Now I've run across Sun's definitions which are exactly the opposite. So my question is, which is the "generally accepted" definition? Or is there even one?

  • What are your feelings on JavaFX?

    - by ForYourOwnGood
    I currently do a lot of work in ActionScript 3.0, I also love to program in Java. Is JavaFX perfect for me? What is the general feeling on JavaFX, will it become a power house, or go down the same path as Java Applets? Could the designers I work with become comfortable with JavaFX to the same extent they are comfortable with ActionScript and JavaScript?

  • HOWTO use UIWebView to display a downloaded file later?

    - by Roboprog
    How do I format an NSURL (what path, or path generator function) so that I can display a downloaded local file (NOT part of the application NSBundle) for use offline? The idea is to snag an HTML file, clean it up and stash it in the iFoo application specific storage area, then later use UIWebView to display it. Next, I go off to RTFM about working with files on iFoo (iPhone / iPad) in general, but any fast-start tips are appreciated.

  • Multithreading, when to yield versus sleep

    - by aaa
    hello. To clarify terminology, yield is when thread gives up its time slice. My platform of interest is POSIX threads, but I think question is general. Suppose I have consumer/producer pattern. If I want to throttle either consumer or producer, which is better to use, sleep or yield? I am mostly interested in efficiency of using either function. Thanks

  • How to implement a caching model without violating MVC pattern?

    - by RPM1984
    Hi Guys, I have an ASP.NET MVC 3 (Razor) Web Application, with a particular page which is highly database intensive, and user experience is of the upmost priority. Thus, i am introducing caching on this particular page. I'm trying to figure out a way to implement this caching pattern whilst keeping my controller thin, like it currently is without caching: public PartialViewResult GetLocationStuff(SearchPreferences searchPreferences) { var results = _locationService.FindStuffByCriteria(searchPreferences); return PartialView("SearchResults", results); } As you can see, the controller is very thin, as it should be. It doesn't care about how/where it is getting it's info from - that is the job of the service. A couple of notes on the flow of control: Controllers get DI'ed a particular Service, depending on it's area. In this example, this controller get's a LocationService Services call through to an IQueryable<T> Repository and materialize results into T or ICollection<T>. How i want to implement caching: I can't use Output Caching - for a few reasons. First of all, this action method is invoked from the client-side (jQuery/AJAX), via [HttpPost], which according to HTTP standards should not be cached as a request. Secondly, i don't want to cache purely based on the HTTP request arguments - the cache logic is a lot more complicated than that - there is actually two-level caching going on. As i hint to above, i need to use regular data-caching, e.g Cache["somekey"] = someObj;. I don't want to implement a generic caching mechanism where all calls via the service go through the cache first - i only want caching on this particular action method. First thought's would tell me to create another service (which inherits LocationService), and provide the caching workflow there (check cache first, if not there call db, add to cache, return result). That has two problems: The services are basic Class Libraries - no references to anything extra. I would need to add a reference to System.Web here. I would have to access the HTTP Context outside of the web application, which is considered bad practice, not only for testability, but in general - right? I also thought about using the Models folder in the Web Application (which i currently use only for ViewModels), but having a cache service in a models folder just doesn't sound right. So - any ideas? Is there a MVC-specific thing (like Action Filter's, for example) i can use here? General advice/tips would be greatly appreciated.

  • How do I strip local symbols from linux kernel module without breaking it?

    - by Kimvais
    If I do --strip-debug or --strip-unneeded, I have the .ko that lists all function names with nm, if I do just strip foo.ko I have a kernel module that refuses to load. Does anyone know a quick shortcut how to remove all symbols that are not needed for module loading so that people cannot reverse engineer the API:s as easily? PS: For all you open source bigots; this is something that general public will never be using in any case so no need to turn the question into a GPL flame war.

Any input is greatly appreciated. Im not sure how Id mark the best answer, perhaps leave it to the community to vote for it.

  • Agile Whiteboard Software

    - by PaddyC
    Can anyone recommend decent software that could replace a physical whiteboard, as used in Agile development? I've had a look at http://www.brightgreenprojects.com/ but ideally we'd like something we could host ourselves. We use Jira for issue tracking, and are looking at integrating GreenHopper for project management at the moment. The general feeling among users so far seems to be that GreenHopper is a little clunky. Is there a more straight-forward agile whiteboard software tool out there?

  • Intents? How to register to be alerted for incoming emails?

    - by Justin
    Extreme Android developer newbie here...well, new to Android development, not development in general. I want to write an application that gets notified when emails come into the device, and takes various actions based on data in the email (subject, sender, to, etc). I think what I have to do is create a BroadcastReceiver with an IntentFilter. The problem I'm having is figuring out what Intent(s) I need to "listen" for. Can anyone point me in the right direction? Thanks.

  • C++ performance, for versus while

    - by aaa
    hello. In general (or from your experience), is there difference in performance between for and while loops? What if they are doubly/triply nested? Is vectorization (SSE) affected by loop variant in g++ or Intel compilers? Thank you
