  • Is code clearness killing application performance?

    - by Jorge Córdoba
    As today's code is getting more complex by the minute, code needs to be designed to be maintainable - meaning easy to read, and easy to understand. That being said, I can't help but remember the programs that ran a couple of years ago such as Winamp or some games in which you needed a high performance program because your 486 100 Mhz wouldn't play mp3s with that beautiful mp3 player which consumed all of your CPU cycles. Now I run Media Player (or whatever), start playing an mp3 and it eats up a 25-30% of one of my four cores. Come on!! If a 486 can do it, how can the playback take up so much processor to do the same? I'm a developer myself, and I always used to advise: keep your code simple, don't prematurely optimize for performance. It seems that we've gone from "trying to get it to use the least amount of CPU as possible" to "if it doesn't take too much CPU is all right". So, do you think we are killing performance by ignoring optimizations?

  • Visual Studio WCF Application now asking to manually attach to process

    - by JL
    I have a console app that is calling a WCF app hosted in IIS. Up until now everything has been fine and I am able to debug the app - step through it without any problems... Until I added my dev pc to a domain.... now every time I get step into the code hosted in IIS, a popup comes up asking if I would like to attach to this process... I can then continue debugging... again not a huge train smash - however... now it randomly just jumps to the end of the process (almost like some kind of timeout) and I am not able to reliably step and debug the IIS hosted code.... Any ideas? All the projects are in the same solution, and all running on the local dev pc... Using Visual Studio 2008, dev PC is Win 7

  • Silverlight 4 application on localhost runs extremely slow

    - by rams
    Silverlight 4 app running in IE8 and hosted on VS2010 internal webserver. The website takes atleast a minute to download the xap and code runs slow on client (IE8). I am running the app in debug mode and have turned intellitrace off. Symbol loading is also turned off. However if I kill the VS webserver, clean the solution, the app runs fast. 3 debugging sessions later, the app slows to a crawl. Have also tried turning off McAfee live scanning but no use. Looked in event log for any clue but found none. What could be the cause of the slowness? TIA rams

  • Memory randomization as application security enhancement?

    - by Paul Sasik
    I recently came upon a Microsoft article that touted new "defensive enhancements" of Windows 7. Specifically: Address space layout randomization (ASLR) Heap randomization Stack randomization The article went on to say that "...some of these defenses are in the core operating system, and the Microsoft Visual C++ compiler offers others" but didn't explain how these strategies would actually increase security. Anyone know why memory randomization increases security, if at all? Do other platforms and compilers employ similar strategies?

  • what's wrong with concatenation in blackberry application?

    - by sexitrainer
    For the life of me, I can't understand why adding a concatenated string to the MainScreen is causing the BB simulator to throw an exception. If I run a VERY simple hello program with the following control, all is well: RichTextField rtfHello = new RichTextField("Hello There !!!"); add(rtfItemDescription); But if I add a concatenated string, the entire app breaks: String MyName = "John Doe"; RichTextField rtfHello = new RichTextField("Hello There !!!" + MyName); add(rtfItemDescription); So what am I doing wrong? Why would the simulator throw an exception for the second example?

  • Best way to daemonize Java application on Linux

    - by SyBer
    Hi. While I found this question being answered here on SW several times, I didn't find a concluding answer what is the best approach. I'm not looking to use any external wrapper, as I found them launching the java process under a nice level lower then themselves which potentially lowers the performance, so it seems only the shell methods are left. I so far found 3 different shell methods: start-stop-daemon RedHat daemon init.d function nohup on start / disown after start What you people are using, and can recommend as the most reliable method? Thanks.

  • UIViewController is popped from view stack and NSURLConnection crashes the application

    - by rickharrison
    I am pushing a UIViewController onto a UINavigationController. This view controller immediately starts a download of an xml feed and then parses it. However, if you hit the back button before it is done downloading, and crashes with EXC_BAD_ACCESS. The line that is crashing it is in parserDidEndDocument and is this line: if (self.delegate && [self.delegate conformsToProtocol:@protocol(ModelDelegate)]) [self.delegate modelDidFinishParsing:self]; I assume it is crashing because it is trying to access self.delegate which is not assigned anymore. How do I get around this? Also, I would release the model object in the modelDidFinishParsing method. How would I release this model if it never reaches this method.

  • Using WPF class in a web application, problem with hosting permission

    - by tanathos
    I'm developing a DLL that uses WPF classes to make image manipulation. It works fine in my local environment, but when I try to use it in an hosted web site I retrieve this error: Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed. exactly when I try to call the EndInit() of a BitmapImage object: BitmapImage originalImage = new BitmapImage(); originalImage.BeginInit(); originalImage.CacheOption = BitmapCacheOption.OnLoad; originalImage.UriSource = new Uri(physical_imagepath); originalImage.EndInit(); Any suggestion?

  • Python, implementing proxy support for a socket based application (not urllib2)

    - by Terry Felkrow
    Hey guys, I am little stumped: I have a simple messenger client program (pure python, sockets), and I wanted to add proxy support (http/s, socks), however I am a little confused on how to go about it. I am assuming that the connection on the socket level will be done to the proxy server, at which point the headers should contain a CONNECT + destination IP (of the chat server) and authentication, (if proxy requires so), however the rest is a little beyond me. How is the subsequent connection handled, specifically the reading/writing, etc... Are there any guides on proxy support implementation for socket based (tcp) programming in Python? Thank you

  • How do I use jQuery for click event in iPhone web application

    - by Gazzer
    When I use jQuery for a simple click event it only works for links.

  • Application Design in Interface Builder Challenge

    - by Sheehan Alam
    I want to design an app that launches other sub-apps. Main View will contain 4 buttons. Clicking on each button respectively will launch the other sub-apps. Each sub-app will have a UITabBarController which has its own different views. At any point I want the user to be able to go back to the Main View from any of the sub-apps. I am not sure how to design this in IB.

  • Application Profiling: Memory Usage

    - by Abs
    Hello all, I have switched on the Codeigniter profile (very useful) and I have noticed that a page of mine shows the memory used as: 2,405,496 bytes That's ~2MB and it's for one request - does it mean if 1000 users accessed this page at the same time, memory usage will be 2GB? Have I got my maths wrong or is there more to this than just multiplying two numbers? Thanks all for any help

  • rails contoller defaults to respond with application/xml in production

    - by Dave Paroulek
    I have a standard contacts_controller.rb with index action that responds as follows: respond_to do |format| format.html format.xml { render :xml => @contacts } end In development, it works as intended: when I browse to http://localhost:3000/contacts, I get an html response. But, when I start the app using capistrano on a remote ubuntu server and browse to the same url, I get a xml response? If I go to http://remote_host:8000/contacts.html, then I see the html response. If I comment out the format.xml { render :xml => @contacts }, then I see the desired html response. Pretty sure I'm missing something subtle about difference between rails development and production modes? Any ideas about what I'm overlooking? Thanks, - Dave

  • how to deploy web application directly from git master branch

    - by mobile.linkr
    For educational purpose, I am writing a server instance in GCE(google compute engine) to serve a few web apps mostly (to be) written in Dart and Polymer. My workflow is, when my students log-in the server above, they will automatically fork those web apps into their own registries in their own server instances for further development. My issues are, How to serve web applications(they are git registries as well) in GCE like Github Pages? Is it possible to manipulate Github Pages to serve web apps mostly using Dart and Polymer packages? Thanks in advance.

    I have Silverlight 3.0 applications with some custom graphic and some charts. I need to find a best way to transfer this graphic to PowerPoint presentation. I`we read that Silverlight 4.0 offers new Clipboard API, but there is only support for Unicode-text, not images.
