I am interested to test CockroachDB on a cluster of PIs. Anyone knows if this this currently possible considering they are still in Alpha?
This may be a little late, but I recently got CockroachDB running on a Pi. The steps I had to take are available here. This is a point-in-time guide to getting Cockroach working on a raspberry pi, so the necessary steps may change in the future, and we still don't officially support ARM architectures. Please reach out on GitHub if you have any issues following the steps!
CockroachDB has so far only been tested on 64-bit x86 platforms (a note in CONTRIBUTING.md says that a 64-bit build is required). It probably won't work on the Raspberry Pi out of the box; I'm not sure what it would take to get it working there.

I want to use Qpid Proton on the raspberry pi 4 but I have trouble installing it.
Well, it seems I could install it and I can use the examples from the Apache website.
https://qpid.apache.org/releases/qpid-proton-0.33.0/proton/python/docs/tutorial.html
However, the container's on_sendable callback does not seem to be executed.
After doing some research, it seems I need to add a topic exchange with the qpid-config, which is part of qpid-tools.
However, those are not available to install, both with pip or apt ...
Do you know how I can install Qpid-Tools on the raspberry pi?
Do I need to add a repository? And if so, where do I find it?
It's doubtful that there exists a build of qpid-tools fir the ARM based distributions so the short answer is probably that you can't get those tools there. The longer answer would be that you would need to likely build the qpid C++ binaries yourself on your Raspberry Pi using the included INSTALL instructions to try and reverse engineer the needed requirements and platform configuration that would allow it to build on ARM.
If you figure out the requirements you could feed that back to the Qpid community although I don't think there is much ongoing momentum for the Qpid C++ broker.
You can download the source bundle from the Qpid project site here.
I am struggling on how to make a Raspberry Pi app for Raspbian (On a raspberry pi). I have searched and searched for hours but I still can't find out how to make one. There are apps that I can use but I cannot install them. Should I use python??... Please help me!!...
I found a few visual editors like XOJO, I am knew to "RASPBERRY PI" stuff.
It's just a bare machine you can cover it with anything you want. It's basically Lightweight Linux distro which we install mostly on the PI. Can support wide range of applications but IOT related products are more often developed using PI. If this is the case you can start here using android also.

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).
I have a raspberry pi3 but I am having tremendous issues with trying to install win10 IOT on it. When I download the core and try to boot it I only get the "rainbow" screen. When installing noobs I dont even get the option for win10 IOT. Anyone else had problems with this? Will it work smoother on a raspberry pi2 rather then the pi3?
Im not asking if anyone know solutions for booting win10 IOT on pi3, I have tried most of it :) Just asking if anyone has better experiences using pi2 for it?
If you follow the link to Manually set up your IoT Core device Microsoft there explain how to install with a Windows computer.
If you are using UNIX however, there isn't much help for you. As an experienced Unix user who last used Windows seriously about six years ago I found it quite intimidating to have to
a) log into my Microsoft account (that I last used from a different continent)
b) sign up as a "Windows Insider"
Even after going through these hurdles I only stumbled across the ISO file by accident, and even then nothing for the Raspberry Pi.
This answer isn't given to help you achieve your aim, which I despair of doing, but to let you know that the whole process perplexed someone of considerable experience. I don't see myself using Win 10 for my Pis without buying a pre-configured SD card.
What you're going to need to do is follow this link and do what it says:
https://buildazure.com/2017/05/24/setup-raspberry-pi-with-windows-10-iot-core/
Basically:
Load up your microsd card onto the PC
Use the wizard
Insert card into the Pi
And boot it up.

Update 1:
Hi friends, could you please recommend me a powered USB hub in Australia(preferred in Melbourne)? I guess my problem is caused by the insufficient power supply.
Hi friends,
I have a FEZ Hydra Basic kit. I got it in 2012 (might be in Sep).
Today I downloaded the latest SDKs, drivers and everything(NETMF and Gadgeteer Package 2014 R1). (.NET Micro Framework 4.3 and the firmware I have on my laptop is 4.2.6.2)
But the firmware on my deivce is 4.1.x.x(I was lucky to saw the device's firmware version just once and I followed the instruction on the software FEZ Config, but failed with errors).
After that, I cannot get the Device's firmware version any more.
I found changing USB ports sometimes help. I have 4 USB ports, some of them can connected to the device, others are not.
So I have no idea to update the firmware in other way.
Could someone please help me to figure out how to find a way to update my firmware?
In the attached image, it shows: the FEZ Config detected the FEZ Hydra and was trying to get the device's firmware version, but it failed to do so and followed by an error message say: Failure - Device is not connected or not responding.
As I mentioned above, I was lucky to see the FEZ Config successfully got the device's version only once.
So my guess is - is it because the output power is not strong enough to support the operation, so I have to use something like a USB hub which has a strong and stable power?(I saw someone mentioned this and cannot find the comments any more).
Bt the way, all USB ports I mentioned above are directly on my laptop which means they get power directly from motherboard, so they should have strong and stable power to support my operations.
I have been stuck at this issue for the whole day, I really hope some friends can help me out.
Thank you very much in advance.
I've had like the same issue. While updating the firmware it threw me that message and I could not reach my Gadgeteer *Fez Hydra at all. I managed to solve it by attaching an external power supply to it. I use the USB Client DP (Dual Power) 1.3. This way you do need the power over USB part and you can safely update the firmware.

edit: If that doesn't solve your isse you might want to reset the Loader first. Which is given as a tip on the GHI website before updating the firmware.
