Are Rebol language implementations small enough to run on cheap experimenter boards like the Raspberry Pi or the BeagleBone? Can it control outputs and GPIO?
I run Rebol 3 on the Raspberry Pi all the time. There is more than enough power to run it. I also wrote a GPIO dialect for Rebol 3 that you can read about in the August 2014 issue of ODROID Magazine (http://magazine.odroid.com) and download from a link in that article. The GPIO dialect was specifically written for ODROID, but could be easily modified for the Raspberry Pi.
Rebol 3 runs well on the Raspberry Pi and I believe it also runs on a BeagleBone.
Use the rebolsource Linux ARMhf build from http://rebolsource.net/
I have not tried using the GPIO functions of the Raspberry Pi yet, but if there is a block device you can read and write to it should be trivial from Rebol.

Is it possible or did someone manage to get TwinCAT BSD running on a raspberry pi?
I heard that ARM devices are not yet supported by this OS, but on the beckhoff website it is stated:
Quote: "FreeBSD supports both 32 and 64 bit platforms and makes scalable systems possible with ARM CPUs extending up to powerful Xeon CPUs"
Source: https://www.beckhoff.com/en-us/products/ipc/software-and-tools/twincat-bsd/
If not, would it be possible via a virtual machine running on the raspberry pi?
Or does it really need to run on top of a x86 or x64 CPU?
PS: I know that it's possible to get it running on VirtualBox on Windows, but I am specifically asking about a solution with a raspberry pi.
TcBSD/TwinCat is currently only available for x86 (32 bit) and x64 (64 bit) Intel and officially only supported on their industrial/embedded hardware.
FreeBSD, however is supported on Raspberry PI:
Raspberry Pi 3/4
I've never tried, but you should be able to install FreeBSD on a Rock Pi X which is compatible with many Raspberry Pi Hats but is Intel based. The Rock Pi X also runs Windows 10 and Ubuntu.
On the question of whether or not you could run TC/BSD on unsupported hardware:
You’d likely need to modify it and it would depend on FreeBSD working on the RockPi X first.
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.

Does anyone know when is Windows IoT Core is expected to officially support Raspberry Pi Model 3 B+?
I've got a project that I need to procure the hardware for - and I'm hesitant to do that before the support is out of the preview.
Raspberry Pi 3B+ is still in a technical preview and there is currently no timeline for a release version.
For a better evaluation experience and for any commercial products, please use the Raspberry Pi 3B or other devices with supported Intel, Qualcomm, or NXP SoCs.
If there are any reasons as to why you cannot use the 3B over the 3B+ for a production solution, please file an issue on our GitHub, here.
First, I googled for this question but found no valid answers (may have been inefficient at this though).
I am working with a mix of Raspberry Pis: Raspberry Pi 1B, 2 B+, 3, Zero. I know that those have different chipsets / architectures etc, but it seems that plugging an SD card created for one Rasberry on a Raspberry of a different model works (I created my SD cards for the 2B+, and plugged them also into other models). I use Raspbian, and I run some code that relies on quite a lot of Python packages (numpy, scipy, etc).
My question is:
Why would this work at all despite different hardware? Where is the hardware taken into account when doing a sudo apt-get install? Are there some parts of a sudo apt-get that depend on the RPi model?
As it seems to be working fine, am I at a risk if I switch cards between different RPi models that the program executes, but that its output is somehow 'wrong'?
Some debian/unix packages need to be compiled against specific CPU architectures. Python source code, for the most part, is transferrable because you are not compiling it onto a specific architecture like you would for C/C++
Regarding the SD cards, I wouldn't trust moving them to different models. There are different Linux kernel requirements at least between Pi-1 and the later models.
Although, I see there is only one link to download Rasbian image, the other OS's specifically say "image for Raspberry Pi 2 and 3"
I'm learning to build a simple bare metal program (without Linux OS) for Raspberry Pi (gen 1).
However, I don't know how to setup the cross-compiler under the hood of xargo. There are docs on rust-cross about RPI 2 but not about RPI 1.
Is there some example how to do it? I've tried several existing repos on github but all failed to compile.
