• ModelVisual3D vs Model3DGroup

  - by bitbonk

  Is there any disadvantage of using ModelVisual3D over Model3DGroup. How much can the resource/performance impact possibly be? ModelVisual3D gives me much more than Model3DGroup does but AFAIK everything that can be done with Model3DGroup can alos be done with ModelVisual3D. So why not just always use ModelVisual3D?

• ORM market analysis

  - by bonefisher

  I would like to see your experience with popular ORM tools outhere, like NHibernate, LLBLGen, EF, S2Q, Genom-e, LightSpeed, DataObjects.NET, OpenAccess, ... From my exp: - Genom-e is quiet capable of Linq & performance, dev support - EF lacks on some key features like lazy loading, Poco support, pers.ignorance... but in 4.o it may have overcome .. - DataObjects.Net so far good, althrough I found some bugs - NHibernate steep learning curve, no 100% Linq support (like in Genom-e and DataObjects.Net), but very supportive, extensible and mature

  - by Hans Klock

  http://findbugs.sourceforge.net/bugDescriptions.html contains a long list of error types. They belong to a category like correctness and performance but do start with an prefix too. EQ for equality is obvious, same like SQL or BIT. But some cryptic. Is there a list what all these prefixes mean?

• Easiest Way To Get Started In Dot Net

  - by Avery Payne

  Ok, so the initial search in StackOverflow shows nothing related for this question. So here it goes: Let's pretend for a moment that you're just getting started in a career in computer programming. Let's say that, for whatever reason, you decide to use the .Net framework as a basis for your programming. Let's also say that you've been exposed to some programming background, but not one in .Net, so it seems foreign to you at first. And lastly, you don't have the benefit of 25 years of exposure to the Win32 API, which explains why it seems so foreign to you when you start looking at it. So the questions are: What is a comprehensive overview of what .Net is? It appears to be a combination of a runtime environment, a set of languages, a common set of libraries, and perhaps a few other things...so it's about as clear as mud. Specifically, what are the key components to .Net? What is the easiest way to understand .Net programming with regard to available APIs? Which language would best suit beginning programming out of the "stock" languages that Microsoft has to offer? (C++, C#, VB, etc.) What are some differences between .Net programming and programming in a procedural language (aka Pascal, Modula, etc.) What are some differences between .Net programming and programming in a "traditional" object-oriented language? (aka Smalltalk, Java, Python, Ruby, etc.) As I currently understand it, the CLR provides a foundation for all of the other languages to run on. What are some of the inherent limitations of the CLR? Given the enormous amount of API to cover, would it even be worth learning a .Net language (using the Microsoft APIs) given that you would not have prior exposure to Win32 programming? Let's say you write a for-profit program with .Net. Can you resell the program without running afoul of licensing issues? Let's say you write a gratis (free) program with .Net. Can you offer the program to the public under a "free" license (GPL, BSD, Artistic, etc.) without running afoul of licensing issues? Thank you in advance for your patience.

• Is ASP.Net State Server an elegant solution?

  - by alchemical

  We have an ASP.Net MVC project that will start with a single web server but likely soon scale into a small web farm. As ASP.Net Authentication stores a UserID, and data caching may also be useful, we would likely need to make the jump to state server fairly soon. I'd like to hear from others how State Server has been to work with and how it scales from a performance perspective. Alternateively, we could architect it as completely stateless by not using data caching and tracking sessions with an encrypted cookie.

• upgrading windows service using inno setup

  - by ofer

  Hi, I've created a basic windows service installation using Inno Setup. both install and uninstall works properly. However, I'm having issues with upgrading the service executable. it is needed to stop the service, and only ofter the service is completly stopped- the new executables should be placed in the target folder. how can I execute a service-stop command and wait for the service to actually stopped before the file copy step is initiate? thanks!

• Singleton object in IIS Web Garden

  - by Anwar Chandra

  I have a lot of Singleton implementation in asp.net application and want to move my application to IIS Web Garden environment for some performance reasons. CMIIW, moving to IIS Web Garden with n worker process, there will be one singleton object created in each worker process, which make it not a single object anymore because n 1. can I make all those singleton objects, singleton again in IIS Web Garden?

• System architecture: simple approach for setting up background tasks behind a web application -- wil

  - by Tim Molendijk

  I have a Django web application and I have some tasks that should operate (or actually: be initiated) on the background. The application is deployed as follows: apache2-mpm-worker; mod_wsgi in daemon mode (1 process, 15 threads). The background tasks have the following characteristics: they need to operate in a regular interval (every 5 minutes or so); they require the application context (i.e. the application packages need to be available in memory); they do not need any input other than database access, in order to perform some not-so-heavy tasks such as sending out e-mail and updating the state of the database. Now I was thinking that the most simple approach to this problem would be simply to piggyback on the existing application process (as spawned by mod_wsgi). By implementing the task as part of the application and providing an HTTP interface for it, I would prevent the overhead of another process that is holding all of the application into memory. A simple cronjob can be setup that sends a request to this HTTP interface every 5 minutes and that would be it. Since the application process provides 15 threads and the tasks are quite lightweight and only running every 5 minutes, I figure they would not be hindering the performance of the web application's user-facing operations. Yet... I have done some online research and I have seen nobody advocating this approach. Many articles suggest a significantly more complex approach based on a full-blown messaging component (such as Celery, which uses RabbitMQ). Although that's sexy, it sounds like overkill to me. Some articles suggest setting up a cronjob that executes a script which performs the tasks. But that doesn't feel very attractive either, as it results in creating a new process that loads the entire application into memory, performs some tiny task, and destroys the process again. And this is repeated every 5 minutes. Does not sound like an elegant solution. So, I'm looking for some feedback on my suggested approach as described in the paragraph before the preceeding paragraph. Is my reasoning correct? Am I overlooking (potential) problems? What about my assumption that application's performance will not be impeded?

• SoapUI JMS Connections

  - by Damo

  I am using SoapUI to do performance testing of some services over JMS using WebSphere MQ as the JMS Provider. SoapUI uses HermesJMS to provide the JMS Connection details for the JMS Endpoint. I've noticed that when I call a request from SoapUI the JMS Connection is never closed. This results in hundreds of SYSTEM.DEF.SVRCONN channel connections. It seems to be specific to SoapUI as HermeJMS doesn't exhibit this behaviour. Has anyone else seen this?

• .NET PerformanceCounter for Hard Faults/sec

  Vista's Resource Monitor includes a reading for "Hard Faults/sec". Is there an equivalent performance counter I can use in C# to get this reading? I've tried the "Page Faults/sec" under the memory category, but that appears to be something different.

• What are the primitive Forth operators?

  - by Barry Brown

  I'm interested in implementing a Forth system, just so I can get some experience building a simple VM and runtime. When starting in Forth, one typically learns about the stack and its operators (DROP, DUP, SWAP, etc.) first, so it's natural to think of these as being among the primitive operators. But they're not. Each of them can be broken down into operators that directly manipulate memory and the stack pointers. Later one learns about store (!) and fetch (@) which can be used to implement DUP, SWAP, and so forth (ha!). So what are the primitive operators? Which ones must be implemented directly in the runtime environment from which all others can be built? I'm not interested in high-performance; I want something that I (and others) can learn from. Operator optimization can come later. (Yes, I'm aware that I can start with a Turing machine and go from there. That's a bit extreme.) Edit: What I'm aiming for is akin to bootstrapping an operating system or a new compiler. What do I need do implement, at minimum, so that I can construct the rest of the system out of those primitive building blocks? I won't implement this on bare hardware; as an educational exercise, I'd write my own minimal VM.

• Delphi 6 - Bugs disappear when I compile multiple times.

  - by Daisetsu

  My Delphi installation has been going downhill for the past few months. It seems though that every so often when I build a release it has strange errors in it which are resolved if I build, then compile, then build, compile, etc. I've talked to another developer who thinks that this is a compiler error. This sort of degrading performance over time has happened on other computers to us too. What does stack overflow think could be the problem.

• Examples of IOC/DI over Singleton

  - by Amitd

  Hi, Just started learning/reading about DI and IOC frameworks. Also I read many articles on SO and internet that say that one should prefer DI/IOC over singleton. Can anyone give/link examples of exactly how DI/IOC eliminates/solves the various issues regarding the Singleton pattern? (hopefully code and explanation for better understanding) Also given a system has already implemented Singleton pattern, how to refactor/implement DI/IOC for the same? (any examples for the same?) (Language/Framework no bars..C# would be helpful) Thanks
