How to implement a UA Server using Milo without any security/certificates? - opc-ua

I am trying to create a demo server using Milo SDK. I have looked at the ExampleServer.java but really confused what's going on with the certificates and security. I am unsure of what KeyStoreLoader and all the other aspects. I just want to create a demo server at the bare minimum with default everything and no security. How would I go about this?

Setup a server on my laptop/desktop for app

I want to setup a server as a backend for my android/web app with mongodb(nosql) (Just like Firebase) on my own laptop/desktop with all the functionality and API.
I read something about creating a server with apache but not sure what to do.
And please tell if there is anything to do of parse server.
Can anyone suggest a video or give great description for this.
Parse Server needs NodeJS not Apache.
Make sure you have installed NodeJs and git to your computer first.

Getting started for team development

I want to start developing with a team using a Neo4j DB, a Spring Boot backend and an AngularJS frontend.
For that, I want to have a Maven Repository and a Jenkins.
To enable my team to use this, I want to have some kind of server at home that can provide remote (sequred) access to the Maven Repo, the Jenkins and the Neo4j DB and that can host the AngularJS frontend communicating with the Spring Backend.
I don't really know where to start. After some googling I found a NAS, but I'm not sure if they suit my requirements.
I've found tutorials for configuring a VPN but there may be a simpler way.
What would you recommend?
So, after some more asking around and googling if found 2 possible solutions, that i want to try out in the future:
First of seems to be the NAS (I've only read about Synology), although it not seems to be intended for my requirements. However there are packages available in the DiskStation OS that allow the installation of a Jenkins, a Maven Repo and Docker, allowing to host a Neo4j DB. I was told, I should be cautious, because only the "x86 diskstation supports docker". At this point I'm not too sure what this means, but since I'm posting an answer, I don't want to keep this knowledge for myself.
I didn't really find anything on hosting applications.
Second solution seems to be, to build a homeserver. In my current understanding, it should suffice to have a spare PC at home for that. All the steps involved should be available under here (german).
I didn't find anything about hosting applications here too, but since this is a "real" system, I'm pretty sure it's possible.
I'm going to try the second one out and keep you updated as far as I don't forget it :)

Is it a good idea to use WAMP server as a web server?

I have bought a VDS (Virtual Dedicated Server) that Windows Server 2008 is installed on it. I needed to use server because I have developed a C# console application that can read data by TCP socket and write them in the MySQL database.
Now I need to start a website on this server. I think WAMP server is so easy for me.
Maybe in future a lot of people visit my website.
Is it a good idea to use WAMP server as a web server?
In principal there is nothing wrong with using WAMPServer as a LIVE webserver.
However, not the out of the box version.
Out of the box WAMPServer and XAMPP for that matter expect to be used as a single seat developer tool and while that is great for a click and go solution to get a developer up and running on Apache/MySQL and PHP in a few minutes it is not secure enough to be considered as a LIVE web facing webserver.
Now if you have the knowledge and experience to create an user account on Windows Server that has access to only what Apache needs to do its work, and can get Apache to run in that account instead of its default account (which has way to many privilages for a live server) and are prepared to explore all the Apache security features/modules that would be required for a web facing server then it is possible. However this is not a trivial task, and any mistakes or ommissions will leave your server open to the simplest of hacks.
In short, unless you really know what you are doing with Windows Server and Apache, you would be far better to pay for a professionally configured and managed web server environment.

How to set up an IDE on a remote server?

Im interested in doing some development from my iPad, and one idea I had would be to code from the safari browser. Does anyone know of a way to set up eclipse on a cloud-based server, so that it can be accessed from a browser?
I believe, you will need the following parts to make it work
The cloud server must be based on one of the supported Eclipse Target Environments.
The cloud server provider must support UI based on some sort of remote desktop - e.g. VNC. Be aware that many cloud providers does not allow UI.
iPad must support the same remote desktop technology. There seem to be many VNC implementations for iPad...
I guess the difficult part is to find a cloud server to use. Though you, as an alternative, could use any PC with an VNC server where you have Internet access...
