  - by DanSogaard

  I'm about to release my application which is built in C# VS2008 to my customer, and I want to prevent copy abuse post deployment, since it's easy to copy installation files to another machine and use the application. I want to limit usage to only one computer per installation.

• PHP - Problem using file_get_contents

  - by shyam

  I have a problem while using the file_get_contents function. I am using it to get a response from a different web server, but it's not returning anything (shown as empty string using var_dump). Also, the problem is only while calling this specific server, because I got result when I used Google's address; and it's working fine in my local machine. I've tried cUrl too - but same result.

• Print layout of C++ object with g++ compiler

  - by zaheer

  Is there a way to print the layout of a C++ object using the g++ compiler or any other means. A simplified example (assuming int takes 4 bytes) class A{ int a; }; class B:public A{ int b; } so the output would be A - 0 4 + a + B- 0 4 8 + A.a + b + It would be useful to understand the layout of objects (in my case virtual machine code). Thanks in advance. Regards, Zaheer

• Developing for iPhone / Syncing the iPhone to another Computer than Dev?

  - by Michael Stum

  Weird question: I have an iPod Touch and plan to get an iPhone once the next generation comes out. Now, my main machine is a Windows PC which is where the iPod is connected to. As I need a Mac to do development, I wonder if it is possible to connect the iPod to the Mac for Xcode/Development but keep it synced to Windows for Syncing? Not sure if this belongs here or on SuperUser though.

• Are there any lightweight analogues to CORBA/RPC for embedded programs?

  - by Mtr

  I am writing embedded applications for different hardware (avr, arm7, tms55xx…) and different rtoses (freeRTOS, rtx, dsp/bios). And every second of them needs to communicate with PC or another digital device. Sometimes interactions logic is very advanced. So I'm interesting in common methodology (like state-machine programming style), protocol specification or library, that could simplify developing such things.

• Parallel computation of the median of a large array

  - by recipriversexclusion

  I got asked this question once and still haven't been able to figure it out: You have an array of N integers, where N is large, say, a billion. You want to calculate the median value of this array. Assume you have m+1 machines (m workers, one master) to distribute the job to. How would you go about doing this? Since the median is a nonlinear operator, you can't just find the median in each machine and then take the median of those values.

• What's the difference between 'service' and 'server'?

  - by bonefisher

  I can imagine that the 'server' can be a machine/host but can be also a program like ftp server, smtp server, etc.. The 'service' on the other hand refers mainly to applications/programms.. Why can then for example the Sql Server cannot be called as Sql Service? It has the same semanthics. Or the other way round: MS Azure service: why it isn't called Azure Server? :)

• Best way to send floating point numbers from .NET to Java and back

  - by Evgeny

  I'm writing a .NET application that will make an RPC call to a Java application (via a message queue). The data sent in both directions will be large arrays of floating-point numbers. What is the best way to serialize them to send them across the wire? I'd like something more compact than text, but architecture-independent as the server may not be an x86 machine. The Java application can be changed as needed.
