Is it a good practice to install ROS (Robot Operating System ) on Windows 10 using a virtual machine ? Are there any limitations that I would face doing so ?.
I know its a basic and simple question. But as a beginner I think I must get help on here
As far as ROS itself is concerned, running it in a Linux VM should be fine. Depending on your usage you may run into trouble brought by software used alongside ROS.
Gazebo for example will likely run very slowly if at all on a VM (though it's true this again depends on hardware). I was unable to get it to run properly on an Ubuntu VM so I just started using Ubuntu as the host OS.
Try dual booting Windows and Ubuntu if you cannot drop Windows entirely.

Since the VideoLAN programmers do write Windows 8/RT/Phone apps using Linux based operating systems and GCC I was wondering, whether there is some progress in regard to how to program for Windows in a Linux environment, where Windows is used only for testing. How easy/ hard is it, to program a Windows RT (modern UI whatever)/ Windows Phone 8 application on Linux?
I imagine a situation, where you use tools such as Git, Emacs/ VIM, GCC, Mono etc. to do the job. How about submitting the app without Visual Studio?
I ask, because Microsoft open-sourced so much stuff now, using Linux based OS for development could (should?) become feasible while developing apps for their systems. Does anybody have some behind the scenes information on this? It is very hard to find some relevant info.
Note I edited this question to be more "straight to the point"

I'm a software engineer at Microsoft so I think I could give you some insights on this.
From a testing perspective, you should definitely have a Windows machine to test against. You can install Windows 8 as a VM using Virtual Box or something similar. You could also remote into a Windows machine if you have access to one.
Visual Studio can't be installed in Linux, as you know, but there are other C#/ASP.NET/etc. IDE's that you can use natively on Linux. Look into Wine for Linux: http://www.winehq.org/about/. It may help you somewhat.
As an aside, developing applications for Windows will be getting easier in the coming months. As was announce at MS Build, Microsoft is moving towards a universal app store that will make your app run on all Windows devices: PC, tablet, phone, and Xbox. This doesn't help with developing apps on Linux, but if you're a Windows developer, you might want to keep your eyes open about the new universal-style apps.
I'm developing C++ apps for Linux, but my workstation is Windows 7. I've read that Visual Studio is the strongest C++ IDE for Windows, but I actually want to execute the code on Ubuntu and be able to use a more graphically pleasing debugger than gdb, although the functionality of gdb is pretty good. I'm really happy with valgrind as well, but again, I'd like to be able to leverage that in an IDE in windows.
I currently use QtCreator as my C++ IDE and I edit the files over a samba mount to the linux box. I use Putty to run the Linux commands. I use git as my source control system, gcc as my compiler and cmake as my build system. I like QtCreator, but as I have it configured, I'm not taking advantage of code-completion or debugging.
The closest thing I've seen is CodeWarrior. It allows for executing code on remote embedded systems and a full debugger. Has anyone ever used this for general app development on Ubuntu?
Is QtCreator the right IDE for me? Is there something else that I can do to configure it so that it'll give me those rich IDE features that I'm looking for? Or should I look to another IDE? Also, are there some tools that I've neglected to mention that would make C++ development easier on a Linux box from a Windows workstation?
Thanks in advance...
It is not clear, you run QtCreator on windows?
If so, you can run QtCreator in Linux,
plus install nxserver on Linux,
and nxclient on windows (http://www.nomachine.com/).
So you run nxclient on windows, login to linux,
and work on linux, in compare with virtual machines,
you get more prefomance.
Use VirtualBox and linux virtual machines?
X Windows.
You could install Cygwin to run an X11 server on your Windows 7 desktop, then run an X11 graphical IDE like QtCreator on your Linux server that renders directly to your Cygwin Windows 7 desktop. I actually tried setting this up with Code::Blocks on openSUSE and Cygwin on Windows 7 just a few weeks ago because I'm in the same situation you're in. It works... kind of. There are weird intermittent errors.
Your scenario is exactly the scenario that the X Windows system was designed for, and it is awesome in concept, but the actual X11 protocol design and implementation is, I gather, old and pretty hairy. I have very little experience with X, but the people who do have lots of experience with it seem to complain about it a lot, and I suppose there are good reasons for that. Too bad, because it would be wonderful if there were a technology like X Windows that worked. AJAX is basically a cheap hack for solving the same kind of problem that X Windows tried to solve... running a remote application with local rendering of a rich GUI.
I gave up on X and I still do the same thing you do: I have putty and Samba-mounted files that I edit with Visual Studio. Visual Studio is the best text editor I've ever used. All the other Visual Studio IDE features are gravy.
There's some solutions :
VmWare : not free but really good
Virtualbox : free but less powerfull than VmWare
KVM/Qemu : Free but less powerfull than VmWare
I need to use Eclipse on a Linux Virtual Box virtualization, Windows XP host, on a laptop. I don't know the specs of that laptop, but it's less than 2 years old.
My first choice of Linux distribution is Ubuntu, but I've heard that in Ubuntu, Eclipse is can be bugged or slow. I don't mind if it's slow. I only need to know if there is a risk that it might not work, since I have a limited time to install and try that.
I would also like to know about any other linux distribution that does or does not work fine for you with Eclipse.
Note: I only need to build a C++ project.
Eclipse runs on Java.
Any linux distro (apart from command line ones) will do.
If you like Ubuntu go with it!
Ubuntu will work just fine as an OS. I use eclipse in Ubuntu running on a VM in a cloud somewhere. So I can just remote desktop into it and pick up where I left off.
Ubuntu should be OK. Just make sure to use the Sun's official Java (its in the repository) and not the openjdk (which is the default). For what I hear, this may speedup the things a little bit.
Disclaimer: I did not try to replace java.
I'd hesitate at suggesting a distro like Ubuntu for your machine -- look at something like Arch which is simple to setup and relatively lean.

I am a newbie in linux and programming. I want to learn linux command and use create some C and C++ programme to interact with the linux API from my windows XP. However, I am not sure how to set up the environment from my windows based computer.
What programme should I install? Also, it seems like linux has Ubuntu, Fedora. I heard of Red Hat as well. What is the difference and which one should I install?
Also, is there any difference between using linux with user interface like Ubuntu, using an IDE to create programme AND the command line terminal using VIM to create programme?
Besides, I have heard of using Valgrind to debug programme. Does Valgrind works together with an IDE in Ubuntu or works in command line terminal only? If my IDE already has debugger, do I still need Valgrind?
Sorry for such newbie questions.
Thanks.
Your question is very vague and prone to start argumentations and fights. Also, you miss-used many terminologies there and before you even start programming with Linux, you should first get acquainted with the OS, especially the terminal... But first things first, programming in C/C++ for Windows is not entirely the same as programming in C/C++ for Linux. If you want the latter, then use the latter.
My suggestion is this :
Grab VirtualBox and install it.
Download Ubuntu ; IMHO, Ubuntu is best for starters (or anyone as a matter of fact) because it has a lot of support, a good user base and is compatible with pretty much any Linux software installer (RPM, deb, etc.) You can choose any other distribution, it doesn't really matter, but I recommend this one. [1]
Start VirtualBox and create a new Ubuntu virtual machine. The steps are pretty straight forward, consult the documentation for any assistance). Your virtual machine may look something like :
1GB of RAM will be enough;
10GB of hard disk (you won't need much more, but you may increase the size if you think you'll need more space for /home, see next point)
a network adapter set a bridged
etc.
Install Ubuntu from the ISO that you have just downloaded (that you have mounted into VirtualBox as a CD-ROM device) You'll only need about 8GB of hard disk total for a typical, minimum Ubuntu installation (ext4+swap), however I recommend this setup.
Enjoy your installation. (Tip: now you can install the VirtualBox's Guest Additions.)
Open a terminal in your Ubuntu VirtualBox window and type sudo apt-get install build-essential to install the GCC compiler
Gedit is already installed by default with Ubuntu and it's a fairly good text editor compared to Windows' notepad. However, vim is not, but you can install it with sudo apt-get install vim in the terminal.
And voilà! You're all set to go to do some C/C++ programming in a Linux environment, where you can still have Windows in case you're stuck.
I also recommend you do most of your learning using the terminal (aka the command line) so you know how things work under the hood. Then, when you are familiar with the GCC compilier, MAKEFILEs, etc. you can install some IDE to avoid repeating tasks; The two best I have yet found are Ajunta and MonoDevelop. Both are available from the repositories.
Now, if you want to "create some C and C++ programs to interact with the linux API from [your] windows XP", You need, for example, to learn sockets and SSH; so you can connect to your Linux machine from your Windows machine and execute some commands remotely from your Windows applications. But before you do that, learn C/C++ and play around with Linux. For a newbie, you already have your hands full right there.
Good luck!
[1] Ubuntu (a Linux distribution) comes with Gnome as GUI, while Kubuntu with KDE and Xubuntu has XFCE. All of them (GUIs) are separate projects and you could have all of them installed on any Linux desktop installation. Even, you don't need any GUI with any Linux distribution; for example, VMWare's Virtual Appliance Marketplate have a whole bunch of ready-to-go Linux installations like that.
Try it with a VM or as a live-cd.
Valgrind is a command-line tool but maybe some IDEs use integrated it.
Under Linux you'll see, than most of the time an IDE is quite useless (not a troll).
You'll do your Makefile manually,...
Hope you'll enjoy' it.
Regards,
Learn 1 thing at a time.
If you want to learn to program first, try python first. It works in Windows and Linux and you get result faster
If you want to learn C++, get Visual C++ express or Cygwin/GCC
If you want to experience with Linux, get a distribution of your choice (Linux-Mint is a good introction, coming from Windows) and try it in a VM (VMWare Player or VirtualBox)
Try easy projects and only after that, worry about debuggers
If you try it in virtual machines (virtualbox or WMWare for example) you can test as many options you want before deciding what Linux distro you will want to use. There are a lot, but from what you listed, my personnal opinion is that Ubuntu is a lot easier than Fedora to start. I've never used RedHat so I can't tell but it hasn't the reputation of beeing a hard one (for experts).
Anyways, at least to start I recommend installing it with GUI (and after starting too unless it's a server...).
Regarding IDEs, you could try Eclipse and Netbeans. They run both on Windows and Linux but I'm not C/C++ programmer so I don't know if they are good at that job. I you don't use IDE, Vim is far from beeing the unique option (Vim "addicts" :) will say it is the unique productive one but that's a personnal choice and the learning time is not very short). Personnaly I prefer a good IDE or at least graphical editors for programming, not that I don't like the power and speed of the terminal with command line as I prefer to use it for system administration or configuration but not for programming where you stay a long time on it.
I don't know about Valgrind but Eclipse or Netbeans IDEs have debuggers of course.

I have Ubuntu 8.04 running on a Xen based VPS server that runs on a dual-core AMD Opteron 64-bit machine.
I have some locally developed C++ based daemons that I would want to deploy in that machine. My local machine is a 32 bit Ubuntu 9.04 running on an Intel core 2 duo laptop.
Can I execute binaries compiled from source code on my machine directly on the above mentioned server?
I am a newbie in this area. Would be great if someone could throw light on the standard practices in this kind of situation.
Thanks in advance
Xen is a hypervisor on top of which OSes are expected to run. It isn't an OS itself, in the normal sense of the word, and you can't build stuff to run on it. Unless the "stuff" is an OS, of course.
EDIT: Since Ubuntu is running inside the hypervisor, Xen itself is somewhat irrelevant. Pretty much anything you can do inside a normal Ubuntu install you can also do inside a Xen-hosted Ubuntu.
WRT deploying 9.04-built code onto an 8.04 system, it will often just work, though you can hit problems with library dependencies. One trick that may help mitigate this if you get into problems is to use debootstrap (apt-get it). It allows you to deploy a minimal Ubuntu or Debian version of your choice into a chroot environment. I've never used it, so caveat lector. A more heavyweight, but cleaner, option is to run a VM on your own system (e.g., Sun VirtualBox) and run 8.04 on it for doing release builds.
It is best to develop with the same OS that you deploy on to minimize differences due to configuration and libraries. It might work, but it could also break in the future when updated libraries are installed. I suggest you get on the same OS or simply recompile the source on the target server
