  • NHibernate second-level cache with external updates.

    - by SztupY
    I've got a web application that is 99% read-only, with a separate service that updates the database at specific intervals (like every 10 minutes). How can this service tell the application to invalidate it's second-level cache? Is it actually important? (I don't actually care if I have too much stale data) If I don't invalidate the cache how much time is needed to the records to get updated (if using SysCache)

  • ASP MVC - Getting Controller Level error handling

    - by RP
    How to get Controller-Level error handling: This is my map-route: routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); And I have 2 controllers - HomeController and AwayController I want both both controllers to handle their own errors For example, a call to /Home/InvalidAction would be handled by one method and /Away/InvalidAction would be handled by another method Where InvalidAction currently results in a 404 as there's no Action method with that name

  • Content controls have to be top-level controls

    - by horatio
    I have a website that can be accessed from www.blahblah.com and special.blahblah.com. The www site always works but occasionly I get a 'Content controls have to be top-level controls in a content page or a nested master page that references a master page' error on the special site. It's exactly the same code running in both situations and the offending page doesn't even have a master page. Why would it work all the time on one and fail sometimes on the other?

  • Problem creating levels using inherited classes/polymorphism

    - by Adam
    I'm trying to write my level classes by having a base class that each level class inherits from...The base class uses pure virtual functions. My base class is only going to be used as a vector that'll have the inherited level classes pushed onto it...This is what my code looks like at the moment, I've tried various things and get the same result (segmentation fault). //level.h class Level { protected: Mix_Music *music; SDL_Surface *background; SDL_Surface *background2; vector<Enemy> enemy; bool loaded; int time; public: Level(); virtual ~Level(); int bgX, bgY; int bg2X, bg2Y; int width, height; virtual void load(); virtual void unload(); virtual void update(); virtual void draw(); }; //level.cpp Level::Level() { bgX = 0; bgY = 0; bg2X = 0; bg2Y = 0; width = 2048; height = 480; loaded = false; time = 0; } Level::~Level() { } //virtual functions are empty... I'm not sure exactly what I'm supposed to include in the inherited class structure, but this is what I have at the moment... //level1.h class Level1: public Level { public: Level1(); ~Level1(); void load(); void unload(); void update(); void draw(); }; //level1.cpp Level1::Level1() { } Level1::~Level1() { enemy.clear(); Mix_FreeMusic(music); SDL_FreeSurface(background); SDL_FreeSurface(background2); music = NULL; background = NULL; background2 = NULL; Mix_CloseAudio(); } void Level1::load() { music = Mix_LoadMUS("music/song1.xm"); background = loadImage("image/background.png"); background2 = loadImage("image/background2.png"); Mix_OpenAudio(48000, MIX_DEFAULT_FORMAT, 2, 4096); Mix_PlayMusic(music, -1); } void Level1::unload() { } //functions have level-specific code in them... Right now for testing purposes, I just have the main loop call Level1 level1; and use the functions, but when I run the game I get a segmentation fault. This is the first time I've tried writing inherited classes, so I know I'm doing something wrong, but I can't seem to figure out what exactly.

  • Eclipse JFace TreeViewer level auto expansion doesn't work

    - by tamm0r
    According to the Eclipse documentation TreeViewer.setAutoExpandLevel(3) means that top-level elements are expanded, and their children, but not grandchildren. I used that in my code, but after setting the input the tree is not auto-expanded, neither on OS X nor on Linux. Expanding the tree manually (via mouse) works flawlessly. Am I missing anything?

  • Convert a post-order binary tree traversal index to an level-order (breadth-first) index

    - by strfry
    Assuming a complete binary tree, each node can be adressed with the position it appears in a given tree traversal algorithm. For example, the node indices of a simple complete tree with height 3 would look like this: breadth first (aka level-order): 0 / \ 1 2 / \ / \ 3 4 5 6 post-order dept first: 6 / \ 2 5 / \ / \ 0 1 3 4 The height of the tree and an index in the post-order traversal is given. How can i calculate the breadth first index from this information?

  • Pretty Pixel-level Picture Painting, Programatically

    - by dreeves
    My mac laptop has 1,024,000 pixels. What's the simplest way to turn my display completely black and go nuts with writing little programs to twiddle pixels to my heart's delight? To make it more concrete, say I wanted to implement the Chaos Game to draw a Sierpinski triangle, at the pixel level, with nothing else on the screen. What are ways to do that?

  • Component Level Documentation

    - by Jason Summers
    I'm trying to make good on a promise I've made to provide a decent set of documentation for a C# component that I've written. I've done some googling and found templates for software design at high and low level. The problem is that all of the templates seem to be geared towards a complete system design as opposed to individual components and are consequently overkill. Can anyone please point me in the direction of a template geared towards component documentation? Many thanks

  • Rails multi level model security

    - by rballz
    I have the need to do the following in Rails to mirror a desktop application: a User and an Office 'owns' a record, if you don't own the record on a user or office level you're kicked into the public realm. user gets read,write,delete to the model record office gets read/write/delete to the model record other or public gets read/write/delete to the model record e.g. UserA owns a model record with read/write/delete OfficeA owns a model with read/write other/public gets read I was wondering if a plugin/gem existed to grant this functionality?

  • "Low level" project using Java

    - by Tammy Wilson
    I'm wondering if it would make sense to do some low level or OS stuff(a project) using Java. Reason why I ask is because I would like to expand my knowledge in Java and I'm into doing stuff like file compressor, bulk file renamer, etc. Are there any examples out there that I can look at or play with? Or should I just be using C or C++ instead? Thanks!

  • Make a target run once at the Solution level in MSBuild

    - by Chandam
    I need a set of tasks that need to be executed exactly once for the entire solution. This will run tasks that will modify each project to run a separate set of tasks for each project. We had done this earlier using a separate project to the solution which had the solution level tasks, but we want to move away from that. Has anyone done this or does anyone have any suggestions on how to implement this?

  • Can defect containment metrics be readily applied at an organizational level when there is only a consistant organizational process framework?

    - by Thomas Owens
    Defect containment metrics, such as total defect containment effectiveness (TDCE) and phase containment effectiveness (PCE), can be used to give a good indicator of the quality of the process. TDCE captures the defects that are captured at some point between requirements and the release of a product into the field, indicating the overall effectiveness of the entire process to find and remove defects. PCE provides more detail at each phase of the software development life cycle and how the defect detection and removal techniques are working. Applying these metrics makes sense at a level where you have a well-defined process and methodology for product development, often a project. However, some organizations provide a process framework that is tailored at the project level. This process framework would include the necessary guidance for meeting certifications (ISO9001, CMMI), practices for incorporating known good techniques (agile methods, Lean, Six Sigma), and requirements for legal or regulatory reasons. However, the specific details of how to gather requirements, design the system, produce the software, conduct test, and release are left to the product development teams. Is there any effective way to apply defect containment metrics at an organizational level when only a process framework exists at the organizational level? If not, what might be some ideas for metrics that can be distilled from each project (each using a tailored process that fits into the organizational process framework) that captures defect containment metrics to discuss the ability of the process to find and remove defects? The end goal of such a metric would be to consolidate the defect containment practices of a large number of ongoing projects and report to management. The target audience would be people in roles such as the chief software engineer and the chief engineer (of all engineering disciplines) for the organization. Although project specific data would be available, the idea is to produce something that quantifies the general effectiveness of all tailored processes across all ongoing projects. I would suspect that this data would also be presented as part of CMMI, ISO, or similar audits to demonstrate process quality.

  • MPMoviePlayerController on large videos causes massive memory spike, and a level 1 memory warning

    - by Shizam
    When viewing images my application hums along nicely with low memory consumption, once I try to watch a video using MPMoviePlayerController memory usage spikes way up, dwarfing the previous memory graph and if I play the video it causes a 'memory warning. Level=1' message. The video files (mp4) aren't even that big, 40MB or so, and it doesn't matter if I play the file streamed from a URL or loaded from a local file, actually the memory spike is even worse if I try to stream it. Here is the code I use to create the player: if (_photo.videoPath != nil) { _movieViewController=[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:_photo.videoPath]]; } else { _movieViewController=[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:_photo.videoURL]]; } [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoMetaListener:) name:MPMovieDurationAvailableNotification object:_movieViewController.moviePlayer]; _movieViewController.moviePlayer.scalingMode=MPMovieScalingModeAspectFit; _movieViewController.moviePlayer.shouldAutoplay = YES; _movieViewController.moviePlayer.controlStyle = MPMovieControlStyleEmbedded; Anybody else running into issues playing video? Also I checked for leaks, there are none reported.

  • UIImagePicker and Memory Warning Level 1

    - by user262829
    Hello, Whenever I use a UIImagePicker to take a picker in my app, I get the following message in the debug console: Receive memory warning. Level=1 I am using the following code: imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera; [window addSubview:imagePickerController.view]; imageView = [[UIImageView alloc] initWithFrame:[window bounds]]; imageView.hidden = YES; [window addSubview:imageView]; [window makeKeyAndVisible]; Does anybody have any ideals? I did not notice this error until I started using the GM Seed for SDK4.
