I deleted my Linux install and recently tried OpenBSD but i am not sure how to set up a GUI environment and xserver. I have a R9 290 gpu and I saw that it should be supported by the radeon driver however I don't know how to download or configure it.
thank you.
All drivers are included in the default install and should Just Work©. That said, your Radeon GPU may need firmware whose license prevents OpenBSD from including it. Running fw_update should install it if it's needed.
Other than that, you just need to configure X. Everything's included in the base system, including the window managers cwm and fvwm. If you want another, you can install it from ports. To configure X, read the very well-written FAQ entry.
Enjoy!

I'm working on a Linux system (a based of OpenWRT version) that has not much storage (<3MB) and no active internet connection, however I need to be able to publish to a MQTT-Broker some outputs. Is there a way for me to install just the publisher part of Mosquitto to save space or another way to solve this issue?
Without a LOT more information about the system this question is basically impossible to answer. e.g. we have no idea about what OS is being used...
But for a system with such tightly constrained storage your best option will probably to build the components you need from scratch that way you have complete control over what gets installed.
You could build the mosquitto tools and then strip them before copying just the binary you want (and any require libraries) to the system.
If you install from pretty much any Linux package management system you are likely to get all the tools plus man pages which will inflate the install footprint.
EDIT -
But all that said, a quick look at the available packages for OpenWRT implies that the existing packages that include both the broker and the command line tools would use 129kb (99 + 30 and is less if you don't need SSL 85 + 28) when installed (this assumes the pre-requisites are already installed)

I'm a little lost (and admit that I'm pretty green to all this). I am looking for the drivers for the M.2 drivers for RHEL/CentOS 8 on x86_64 architecture. Previously I was successful installing the drivers under Ubuntu following the Getting Started guide on the Coral website (https://coral.ai/docs/m2/get-started). But I need to run CentOS 8 for other reasons. So I know that the board works. I know it can be supported in Linux, but don't know how to convert the instructions for CentOS.
My M.2 board is connected to my server using a M.2 to PCIe adapter.
Thanks in advance!

I also believe that you should be able to get this working.
Couple things that you'll need:
libedgetpu.so - You can download the latest runtime from here: https://github.com/google-coral/edgetpu/tree/master/libedgetpu/direct/k8
apex/gasket modules - This is a required kernel module for talking to the pcie module. This is going to be very tricky, first you'll need to make sure that you don't already have apex/gasket module already installed. If you do, blacklist it and load our modules. Now our modules cannot be installed with apt-get since you are in centos, so your only option is to download the code from source and compile it on your own: https://coral.googlesource.com/linux-imx/+/refs/heads/release-day/drivers/staging/gasket

Torch is a scientific computing framework with wide support for machine learning algorithms. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation.
Q:
Is there a way to install torch on MS Windows 8.1?
I got it installed and running on Windows (although not 8.1, but I don't expect the process to be different) following instructions in this repository; it's now deprecated, but wasn't deprecated few months ago when I built it. The new instructions point to torch/torch7 repository, but it has a different structure and I haven't been able to build it on Windows yet.
There are instructions on how to install Torch7 from luarocks, but you may run into issues on windows as well; I haven't tried this process. It seems like there is no official support for Windows yet, but some work is being done by contributors (there is a link to a pull request in that thread).
Based on my experience, compiling that deprecated repo may be your best option on Windows at the moment.
Update (7/9/2015): I've recently submitted several changes that fix compilation issues with mingw, so you may try the most recent version of torch7 and follow the build instructions in the ticket. Note that the changes only apply to the core lib and additional libraries may need similar changes.
This webpage hosted by New York University recommends installing a Linux virtual machine in order to run Torch7 on Windows through Linux. Another option would off course be to install a Linux dist in parallel with Windows 8.
Otherwise, if you don't mind running an older version of Torch, there is a Windows installer for Torch5 at SourceForge.
I think to use a GPU from inside the virtual machine, the processor and the motherboard should not only support VT-x , but VT-d should be supported too.
But the question is, if I use a CPU with VT-d supported, do you think there will be a significant loss in PCIe connections efficiency?
From what I understand,
VT-d is important if I want to give the virtual machines direct access to my hardware components (like PCI Express cards). Like directly attach graphics card to vm instead of host machine. Isn't that mean that the PCIe connections efficiency will be the same just like if it was the host?
I have a toshiba laptop c850, dual core. Toshiba does not provide any driver for Wi-Fi for Ubuntu 12.10. I am currently having problem in using DSL modem, Ethernet and Wi-Fi. Can anyone tell me the solution to this problem?
maybe you will find some information there :

Wireless
A really up to date kernel is required for wireless support, at least
3.5.0 is recommended. Realtek has the Linux drivers available for download but they must be re-complied after upgrades to kernel.
As you commented, you got the Atheros Communications Inc. AR8162 Fast Ethernet Controller.
This is some guesswork here because there are several versions of the driver and some people state only one is working for them, I stick with the most popular for now.
First download this file from another machine:
https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/28/compat-drivers-2013-03-28-5-u.tar.bz2
If you have Ubuntu or another Linux distro on your second machine you can use wget to download the file:
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/28/compat-drivers-2013-03-28-5-u.tar.bz2
Next, use your preferred method (preferably an USB Drive) to copy it to your target machine (Toshiba C850) and use the following commands in a terminal. Make sure you are in the right directory first and use cd to change to the directory where your downloaded file resides.
tar -xzvf compat-drivers-2013-03-28-5-u.tar.bz2
cd compat-drivers-2013-03-28-5-u
./scripts/driver-select alx
make
sudo make install
sudo modprobe alx
If this doesn't work try a reboot first then you can try one of the other versions, I can't tell which will work for you:
http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2012-02-28-p.tar.bz2
https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/04/compat-drivers-2013-03-04-u.tar.bz2

I am studying the boot process in Linux. I am looking through this html page http://www.tldp.org/HOWTO/Bootdisk-HOWTO/x88.html. The first line under the section 3.1 "The boot process" says that "All PC systems start the boot process by executing code in ROM (specifically, the BIOS)".
My doubts are
Who loads the code in BIOS ?
Where is this code in BIOS located ?
To where is the code in BIOS loaded and executed ?
Kindly tell me references where i can get more information
Thanks,
LinuxPenseur
The code is already there in memory when the computer is powered on. It is in non volatile memory, meaning it doesn't disappear when the computer is turned off.
So the code is already there in a specific memory address, and the processor starts by running it.

A good question! Actually you do not need to reformat the HDD or even reinstall the OS on it unless the new PC is unable to run the existing OS on the drive.
Commonly, if you did a simple install of a Linux distribution, you would have no trouble moving the HDD to a new system and just running it. But if the OS is a version of Windows, the chances of this being the case are nearly zero: hardware vendors nearly always tune their device drivers for Windows so you cannot even use the same driver for two versions of Windows on the same machine (upgrading from XP to Windows 7 for example, often requires that you redownload at least a few hardware drivers).
And the problem often arises even with Linux if you have installed any high performance drivers. Sometimes you can perform a "recovery boot" from GRUB or LILO and get into a text mode screen with internet access, though. And if you can do that, often you can install the drivers for the new PC on the Linux HDD without doing a complete reinstall of Linux.
In fact, this is actually what that install CD or DVD is actually doing. It boots to a very vanilla flavor of the OS (Windows or Linux), then installs drivers for the hardware it detects, reboots (hopefully with functioning drivers) and wraps up the install process.
