I am trying to learn about Arago, still a beginner. Reading this question gives me the impression that ROS is by default installed in the default Arago image.
Is this understanding correct? Is ROS (or the meta-ros layer) installed by default in Arago?
Any tips where to get more information is very welcomed

I've seen on StackOverflow that's possibile develop a cluster composed of a single node.
My challenge is maybe harder: setting an apache storm environment on a single raspberry pi 3. I know that is a very limited machine to do stream computing, but mine is a research interest. Until now, I have not found system requirements to setup storm on a machine, someone can help me?
Thanks to all
Yes, Ideally it should be possible once you have Linux OS installed for e.g. Ubuntu Mate on Raspberry Pi 3.
You may be required to make sure you have these packages installed:
Java 7
Python 2.
Then follow below link for a basic setup of Storm:
https://github.com/vrmorusu/Storm/wiki/Apache-Storm-on-Cloudera-VM
You may build uberjar files containing Storm topology files on your local machines to avoid installation of maven and other build tool dependencies.
It would be great if you can try this and post your success story or issues seen in this forum. It will help getting more focused answer(s) for problem(s).
So I will start off by saying that I do NOT want know how to setup or run QT on the pi. I am specifically trying to setup Qt Creator 4.0.3 (Based on Qt 5.7.0 (MSVC 2013, 32 bit)) to write and compile C++ and the run it on the Raspberry pi 2. I have found that running qt on the pi is far to slow.
I have searched for two days to find the right toolchain download for qt/raspberry and its corresponding qt configuration. Nothing seems to work. I have found what seems like a thousand dead ends searching the web. I can write and compile apps for windows console fine. But finding information to cross compile for raspberry seems to be an elusive Unicorn!
Does anyone have this working??? If so which of the many toolchains did you use? And please help me replicate your QT configuration. The closest I have come is using the GCC ARM Embedded toolchain but I cant seem to get the QT options set correctly and I believe that only gets me part of the way there. My ultimate goal is to control GPIO and use the RadioHead library.
Thanks in advance!
I also wanted to do that, and I actually achieved it, It's called "cross-compilation", you build on the Main PC and then compile it to the target.
Initially I wanted to use my main PC with windows 10, but I ended creating a linux partition on my pc to do it since I didn't found any way to do it with windows.
Qt has a very comprehensive tutorial with Qt5 and RaspberryPi2 (both with linux), the only problem is you need linux on your pc to do it. If you want to do this I would suggest following this steps:
Create a linux partition with the same os as in the pi (for example raspbian and debian) and name the username (in linux) "pi" and the password "raspberry". This will help you with external libraries.
Install Qt for Linux on your new partition
Follow Qt's tutorial on https://wiki.qt.io/RaspberryPi2EGLFS
The tutorial is really straightforward, I really recommend it.
Good Luck.
I am a newbie to Xen and want to download it on my machine which currently has CentOS7. I have been researching and experimenting for a couple of days but can't seem to find a straightforward answer on how to install a fully functioning Xen on CentOS7. I tried using the workaround at http://www.lairdscomputer.com/Blog/tabid/62/EntryId/74/Installing-Xen-4-on-Centos-7.aspx, but it seems that some of the packages it uses might be outdated.
Is it even possible to install Xen on CentOS7, even if it is missing some parts to it? Would it be better just to go back to CentOS6.x so that I can install Xen4CentOS?
Thanks in advance! Any advice is appreciated!
Afaik RedHat therefore CentOS is not supporting Xen whoever in fact it is possible.
I am using xen4centos on my Centos7 server, it was installed along with official article from wiki:
https://wiki.centos.org/HowTos/Xen/Xen4QuickStart
It it is not, please provide some logs, errors etc
I have a face recognition program developed in matlab , I want to get results or output in robot operating system (ROS) also installed on my computer both matlab and ROS are on Ubuntu.
How can I interface both matlab and ROS?
There is ROS io matlab package, have a look here
http://www.brendanandrade.com/2014/02/12/ros-i0-getting-started-with-mathworks-new-ros-package-for-matlab-p1/
Matlab 2015 is supporting ROS as well.
You can connect matlab with ROS with the Matlab-ROS toolbox.
There are plenty of matlab-ros guides available, such as:
https://nl.mathworks.com/help/ros/ug/work-with-basic-ros-messages.html
The approach of such guides is commonly:
Set up connection (e.g. set ROS_IP / ROS_MASTER_URI, create a ros-1 core if you have none running yet)
Create a matlab publisher object that streams your data (messagetype of your choice, depending on the results you want to output) on a topic.
Connect other components by setting up subscribers (on matlab or in other frameworks) that listen to updates on the specified topics.
Matlab-ROS-toolbox allows interfacing with ros on both Windows and Linux, which does not require you to install ROS on your device.
Having ROS installed allows various features such as interaction through terminal (e.g. rostopic list).
I want to run multiple versions of MATLAB (with standalone licenses) on a Windows XP home computer. One is MATLAB R2007b and the other is MATLAB R2009a. I found some docs online (link and link), but nothing related to the latest versions. Has anyone tried this?
You can do that, just install the new and the old versions in different directories.
FWIW if you have the chance to run MATLAB R2009b rather than R2009a, you might want to. I haven't looked in detail at the release notes yet, but I noticed already that the language in Simscape has been improved in R2009b + now I have to reinstall it yet again to get the upgrade...
I've been running MATLAB both on my desktop and in a virtual machine successfully for a while now. I happen to be running the same version in both right now, but there's no reason why you couldn't run different versions in and out of the VM. This setup allows me to keep a stable working version of my application available that I can rely upon to satisfy the need to rapidly analyze data while simultaneously having a separate development version that may or may not be fully functioning at any particular time.
You could use Octave which is an open source 'alternative', should sort the issue out nicely
