Blockchain : Hyper Ledger Fabric Installations in Windows 10 - docker

I have visited almost all the links available for the installation of Hyper Ledger in Windows 10.
I have installed:
Git
Docker
Ubuntu Bash
Npm
NodeJS
And almost all other things that were mentioned in those links. But at the end of those links, running and installing Hyper Ledger fabric. I get errors of not available binary samples.
Some links that lead me to something, but an error in the end.
Link1
Link2
Please, anyone, tell me a way of installing and running Hyper Ledger Fabric on Windows 10. I have to make a Mobile Application on Hyper Ledger Fabric.
It will be a blessing for me if someone also can tell me how and using what tool I can make Mobile Application using Hyper Ledger Fabric.

Be careful: Hypereldger Fabric is actually not supported for Windows. You must run it in Linux.
I know there are some guides online but follow the documentation.
While your Java/Python/Go/Node SDK can be run on Windows, the network must be on Linux.
That's not impossible to run it on Windows, but they do not assure you will be able to do this.
Maybe support for Windows will come in next versions.

Where to find legacy mbedtls documentation?

I am looking for the legacy mbedtls documentation.
It was available at tls.mbed.org before joining the trustedFirmware project. Now, sadly, it is not reachable anymore.
Thanks!
tls.mbed.org only had the latest version, and then it froze at some point and was showing an old version until it went down. I haven't found a site hosting multiple versions of the documentation.
You can typeset the documentation on a typical Unix-like system (e.g. Linux or macOS or WSL or Cygwin) by checking out the version you want from the GitHub repository. This has the advantage that you can typeset the documentation for your configuration: after setting mbedtls/mbedtls_config.h (mbedtls/config.h in Mbed TLS 2.x), run
make apidoc
and browse apidoc/modules.html or apidoc/files.html.
If you want the whole documentation including all compile-time options and features that may or may not be enabled in your build, run
scripts/apidoc_full.sh
Note that this overwrites mbedtls/mbedtls_config.h.

ERROR: Couldn't connect to Docker daemon at http://0.0.0.0:2375 - is it running?

I am watching a course on Hyperledger Composer development online. I installed all the required prerequisites, docker, docker-compose, nodejs, golang. After cloning the fabric-samples repository from github. There is a file called byfn.sh inside a folder called first-network. On running the command ./byfn.sh up, it's giving the following error:
If, someone has experience working on it, please help. Any help would be appreciated. Thank you.
I think the first thing you should do is stop looking at or trying to use Hyperledger Composer. It is end of life now and some of it's components will have problems even if you install the exact required versions (for example the rest server fails to launch now on node 8 but changing to a newer version of node may break other parts of Composer).
As you had planned to use it with hyperledger fabric I would suggest that you just invest your time in Hyperledger fabric, see https://hyperledger-fabric.readthedocs.io/en/latest/
Regarding your problem with docker, I suspect you tried to install docker through the apt command in your wsl window ? I'm guessing that you are using WSL2, but if you are using WSL1 then docker will never work in a WSL1 environment. If it was WSL2 then the docker daemon doesn't automatically start in that environment you need to start it yourself first. I think the command is service docker start. The important thing here is to make sure you are using WSL2 and not WSL1 (see hyperledger fabric link later which provides guidance on making sure you are using WSL2).
An alternative to installing docker into WSL2 directly would be to install Docker Desktop for Windows and follow the hyperledger fabric instructions here https://hyperledger-fabric.readthedocs.io/en/latest/prereqs.html#wsl2

Step by Step Setup Guide to Neo4j Mazerunner in Windows

I would like to use the Spark-graphX packages available to Neo4j through Mazerunner, however I am an analyst and not a software person. I am running Windows 7 on my laptop and Neo4j 2.3.0, and would like a step-by-step guide explaining how I can set-up Mazerunner for both Community & Enterprise. There's a lot of mention of dockers and containers, and I have no idea what these are, or how to set them up. Simple instructions would be of sooo much help! :)
Docker is primarily Operating System Level Visualization technology designed to run on Unix based systems (Linux,Mac,FreeBSD). Luckily Docker provides a Windows version that sort of does the same thing on Unix.
What happens is, after you have installed Docker, it allows you to run what they call containers which are basically virtual machines on top of your host (Windows 7 Running Docker). This allows you to run services like Neo4j in an isolated environment. Docker also allows you to download and install pre-configured, pre-compiled images of operating systems that usually provide some sort of service or have some software pre-installed.
In your case, I believe all you have to do is:
First install Docker
Use "Docker Compose" to download and install the images.
Continue Reading the Tutorial as you have now installed the required docker images
Note: Some of the operations, like the one in Step 2 will require command-line access and Also the creation of a "docker-compose.yml" so, be sure to visit all the links I have provided. Spend a little time going through them and you should be alright.
PS: great blog. definitely bookmarking it!

How to install Torch on windows 8.1?

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?

How to set-up vicidial in local system?

I want to set-up vicidial in my local computer server any information or a document for that?
I googled but I can't find exact resource.
I googled below links.
Link 1
Link 2
Thanks in advance.
Vicidial is an Open Source Predictive AutoDialer based on Asterisk with PHP/MySQL/Perl coding.
Installation of Vicidial is only viable on a Linux machine.
There are several locations with Scratch Install instructions for Ubuntu and CentOS. In fact, the Vicidial Wiki has a list of a few of them: http://wiki.vicidial.org/index.php/VICI:Installation
Most are quite old except for the Goautodial.com which has instructions for CentOS installation by adding the goautodial repositories and then just upgrading the OS to get all the necessary packages.
If you're not using CentOS or Ubuntu and none of those instructions work for your purpose, beware that Vicidial installation is not easy. It is MUCH better to dedicate a machine to the purpose by installing from Vicibox.com's .iso image which will wipe the computer clean. The installation becomes easy and then you need only argue with configuration.
If you can not dedicate a machine to this purpose, you should take the earlier suggestion of a Virtual server (vSphere or Virtualbox both work for Vicibox.com's .iso installer), but beware that you'll only be able to have one or two agents on the virtual dialer at the most. Luckily, if you do get the virtual vicidial working, it is possible to backup the virtual server's database and install it on a hardware based server later to bring everything with you without having to do it all over.
