  • How can I make a career in Formal Methods programming in USA?

    - by A5al Andy
    I've found that my (USA) professors recoil with a near-disgust when I ask them about how to pursue a career in Formal Methods programming. They say, "Oh, that stuff! That stuff is anal. You don't need that European POS to get a job." I'm sure I'll get a job without it, but Formal Methods interests me so much that I bet I'd like to make a career of it. I'd like to learn about Formal Methods at an American University and then work in that field here. I've found that even professors at more important universities than mine don't seem to welcome Formal Methods. Almost all FM research project webpages are semi-abandoned and moldering. Europe is where the action seems to be for this. Can anyone suggest a plan of attack, and along the way explain the antipathy to Formal Methods in the US? I'm a sophomore at a public university in the South.

  • Virtual channel tutorial for terminal services.

    - by Scott Chamberlain
    I am writing a program that will need to communicate to a server through a TS connection. Virtual Channels seems to be exactly what I need but Microsoft's documentation leaves very much to be desired. Does anyone know of good tutorials or just some examples I could use to help me. Preferred language is C# but C++ examples are fine too.

  • Making(programming) virtual drives on windows XP

    - by Manux
    Ahoy, I'd like to mount a "virtual drive" myself on Windows XP, I guess using the windows API. What I thought about would be like a server interface, meaning explorer.exe would send "queries", like, list directory, or get file through a pipe or whatever... I know some programs do it, maybe not the way I think it is done, but what the heck, if you know anything, enlighten me please!

  • Preference values - static without tables using a model with virtual attributes

    - by Mike
    Im trying to eliminate two tables from my database. The tables are message_sort_options and per_page_options. These tables basically just have 5 records which are options a user can set as their preference in a preferences table. The preferences table has columns like sort_preferences and per_page_preference which both point to a record in the other two tables containing the options. How can i set up the models with virtual attributes and fixed values for the options - eliminating table lookups every time the preferences are looked up?

  • Writing a Virtual Printer in .NET

    - by David Osborn
    I'm looking to create a virtual printer that passes data to my .NET application. I want to then create an installer that installs both the printer and the .NET application. It would we really nice to be able to write it all in C#, but I have a feeling that this will require a printer driver to be written is unmanaged code. Does anyone know of a fairly clean tutorial or example of how to do this?

  • Virtual Cam - Cam Split .NET

    - by Fish
    I'm looking for a virtual webcam driver to use in a .NET project, this project will be GPL, and have no idea how many installations there will be The idea is that the application is using the webcam without locking the device. Found a couple of programs that do the job, but either in application and/or too expensive: * http://www.softservice.org/products_camsplitter.html (9.99$/installation) * splitcamera.com (program, no SDK available) All idea's are welcome

    Hi, I have a VMWare virtual machine (windows xp). I have just started it up through the VMWare player and it's extremely slow on my laptop (expected). Is it possible to boot from that image like in mac bootcamp so that it's not virtualised and soo slow? Thank you

  • Implementing a virtual file system in .NET

    - by Charlie Somerville
    A while back a found a great-looking framework that allowed .net developers to implement a virtual file system. I thought I had bookmarked it, but it seems I haven't. Does anyone know any frameworks for doing this? EDIT: Here's a hint... It had a catchy, short name and it's own domain. Sorry, that's all I can remember :p

  • Template class + virtual function = must implement?

    - by sold
    This code: template <typename T> struct A { T t; void DoSomething() { t.SomeFunction(); } }; struct B { }; A<B> a; is easily compiled without any complaints, as long as I never call a.DoSomething(). However, if I define DoSomething as a virtual function, I will get a compile error saying that B doesn't declare SomeFunction. I can somewhat see why it happens (DoSomething should now have an entry in the vtable), but I can't help feeling that it's not really obligated. Plus it sucks. Is there any way to overcome this? EDIT 2: Okay. I hope this time it makes sence: Let's say I am doing intrusive ref count, so all entities must inherit from base class Object. How can I suuport primitive types too? I can define: template <typename T> class Primitive : public Object { T value; public: Primitive(const T &value=T()); operator T() const; Primitive<T> &operator =(const T &value); Primitive<T> &operator +=(const T &value); Primitive<T> &operator %=(const T &value); // And so on... }; so I can use Primitive<int>, Primitive<char>... But how about Primitive<float>? It seems like a problem, because floats don't have a %= operator. But actually, it isn't, since I'll never call operator %= on Primitive<float>. That's one of the deliberate features of templates. If, for some reason, I would define operator %= as virtual. Or, if i'll pre-export Primitive<float> from a dll to avoid link errors, the compiler will complain even if I never call operator %= on a Primitive<float>. If it would just have fill in a dummy value for operator %= in Primitive<float>'s vtable (that raises an exception?), everything would have been fine.

  • Virtual function - including some html

    - by Ockonal
    Hello, I have a php-file which includes another html-file: <? virtual("../top.html");?> The problem is that any code before this include compiles and runs well, after - nothing. There aren't any errors etc. After commenting this line, everything works. Code was written under local computer with ArchLinux + LAMP. Now I have ubuntu 10.04 with the same configuration. What could it be?

  • How to install Ubuntu over http in virtual manager?

    - by Bond
    Hi, I am having a situation where I can not use a CD or PxE boot or wubi to install.I need to necessarily do an http install of Ubuntu.I am basically trying to create a guest OS in a virtualization setup on Xen on a non VT hardware. On a non VT hardware the virt-manager does not allow to install from local ISO or PXE even the only option is via a URL on http:// Here is what I did: 1) Download ubuntu 10.04 32 bit ISO 2) Kept it in /var/www (apache2 is running) 3) renamed it to ubuntu.iso and when I reached a stage where installation begins I gave path hxxp://localhost/ubuntu.iso but I got an error any installable distribution not found. 4) After this I did mkdir /var/www/sk mount -t iso9660 /var/www/ubuntu.iso /var/www/sk -o loop and this time during the installation I gave path http://localhost/sk I was able to see the contents in browser http://localhost/sk which you will see in a normal CD. But beginning installation I got same error ValueError: Could not find an installable distribution at 'http://localhost/sk So I want to just confirm if http install is done only this way or some other way because the installation is not proceeding.

In this tutorial, you will create a Java EE 6 Web Application and add the following components to it - a Stateless Session Bean with two asynchronous methods. You define a Servlet to call the asynchronous methods and to keep track of the invocation and completion times to demonstrate the asynchronous nature of the method calls. The index.jsp will contain a form with a submit button, Run allowing you to execute the application. The form will submit to the Servlet which invokes the asynchronous methods defined in the session bean and the response is re-directed to response.jsp. Information about the asynchronous handling procedure is displayed to users. From this information, users will notice that the invoker thread and the called asynchronous thread are working concurrently. Check out this new OBE on the Oracle Learning Library: Creating Asynchronous Methods in EJB 3.1. This OBE is part of the new EJB 3.1 New Features Series.

  • Do I have to implement Add/Delete methods in my NHibernate entities ?

    - by Lisa
    This is a sample from the Fluent NHibernate website: Compared to the Entitiy Framework I have ADD methods in my POCO in this code sample using NHibernate. With the EF I did context.Add or context.AddObject etc... the context had the methods to put one entity into the others entity collection! Do I really have to implement Add/Delete/Update methods (I do not mean the real database CRUD operations!) in a NHibernate entity ? public class Store { public virtual int Id { get; private set; } public virtual string Name { get; set; } public virtual IList<Product> Products { get; set; } public virtual IList<Employee> Staff { get; set; } public Store() { Products = new List<Product>(); Staff = new List<Employee>(); } public virtual void AddProduct(Product product) { product.StoresStockedIn.Add(this); Products.Add(product); } public virtual void AddEmployee(Employee employee) { employee.Store = this; Staff.Add(employee); } }

  • How does object of sub-class record information about its super-class the in a Virtual Inheritance

    - by Summer_More_More_Tea
    Hi there: I encounter this problem when tackling with virtual inheritance. I remember that in a non-virtual inheritance hierarchy, object of sub-class hold an object of its direct super-class. What about virtual inheritance? In this situation, does object of sub-class hold an object of its super-class directly or just hold a pointer pointing to an object of its super-class? By the way, why the output of the following code is: sizeof(A): 8 sizeof(B): 20 sizeof(C): 32 Code: #include <iostream> using namespace std; class A{ char k[ 3 ]; public: virtual void a(){}; }; class B : public virtual A{ char j[ 3 ]; public: virtual void b(){}; }; class C : public virtual B{ char i[ 3 ]; public: virtual void c(){}; }; int main( int argc, char *argv[] ){ cout << "sizeof(A): " << sizeof( A ) << endl; cout << "sizeof(B): " << sizeof( B ) << endl; cout << "sizeof(C): " << sizeof( C ) << endl; return 0; } Thanks in advance. Kind regards.

  • Non Blocking Keyboard on WinCE accessing the virtual keyboard

    - by Jan H.
    Hello Guys, I am desperately looking for a solution that enables me to read keyboard events in a non blocking way. These Keyboard events are generated by a VIRTUAL KEYBOARD that comes with the WinCE device. I have a console application running in C++, where the user is asked to navigate via 'ESC', 'U' and other characters through the menu. I first tried to use fread and stdin and realised that it is blocking call and waits for a carriage return. Then I tried to hook up to the windows message WM_KEYUP, but I never recieve this windows message. Furthermore I tried to use QtGUI together with the event QKeyEvent, but I never recieve any event. I wonder if it is in general possible to recieve non-blocking keyboard events on a WinCE device. I would be glad if you have any suggestions! Cheers, Jan

  • Access virtualhosts over LAN (Also in xpmode (Virtual PC))

    - by Pheter
    Hi, I am running Wamp on my computer (the host). I have set up several virtualhosts in apache and they are working fine when I access them from the same computer (host). I have installed Windows XPMode on my computer (which is running windows 7). XPMode (which uses Virtual PC) is set up to use a NAT network. The network in XPMode is working fine, and I can access the host PC via the IP address 192.168.1.5, just as I would if I was using any physical computer on the same network. I can view all the web pages at 192.168.1.5 and it's subdirectories. However, I cannot access any of the subdomains that are configured in the virtualhosts of the host computer. How can I access the subdomains? I don't think that the fact that I am using XPMode and am using a virtualized OS has anything to do with it, but I thought that it was worth mentioning.
