I'm planning to create a bot that manages a room of a HTML5/WebRTC browser game which should run 24/7 on my headless server.
It won't be there to participate in the game but only to host a room and extend it with some useful features. But before I even think about implementing those extra features I need to get the basics done.
So I wanted to know which tools I could use to first only access the game like any normal user would, create a room and be a stable host without needing a graphical browser.
I saw in some older post that there are tools like phantom.js but it doesn't seem to support WebRTC.
Thank you in advance

i want to know if it is possible to make a security key out of a normal usb.
i am using webauthn api for php at the moment on a windows 10 device, if you take a quick look at the demo of webauthn and try to register with an usb it wont recognize it as an security key. is there any way to fix this?
i tried using windows aplications like usbRaptor but those will only lock my pc.
Not sure what "a normal USB" actually means, but you need a purpose-built FIDO security key for FIDO2/WebAuthn.
There are many vendors including SoloKeys, HID, Yubikey, TrustKey, and many others. https://fidoalliance.org/certification/fido-certified-products/
I would like to implement a video / audio call feature from a browser. The goal is to allow two users to communicate remotely without having to install a third part (when I say third part, I'm talking about a software or an extension on a browser).
I know WebRTC, which is very popular today and free. However, it is very difficult to implement and the documentation is difficult to understand (not very easy for a beginner).
Here is the official webRTC documentation, and honestly, where to start? https://webrtc.org/start/
If you have an experience about WebRTC, is it possible to share with positive or negative points? This would be very useful for the community.
Moreover, if you have experience with another library, I think it would be interesting to hear it.
There is no other way to develop a call service in a website without the use of WebRTC today.
The alternatives are:
Use WebRTC
Use Flash (which is... dead)
Use a plugin (which is... dying as a mechanism in browsers)
Use an app you download (not exactly a service in a website)
Node.js is the way to go, but you will need to learn some new technology, especially when it comes to the backend.
The servers you will need are:
1. The traditional web application server
2. A signaling server (the one you plan on using Node.js for - you can use that for the web application server as well)
3. A STUN/TURN server (for NAT traversal)
4. Maybe a media server, depending on your use case

As far as I understand, Microsoft wants to allow "having both desktop and modern ui GUIs" only available for web browsers (am I mistaken here ?).
Does that mean common apps will be developped twice ? With e.g Skype being available both as pure desktop app and pure modern ui app ? And if a user installs both, these both instances will share no data ?
I can't imagine them doing a shift towards gesture friendly uis/hybrid ui, and leaving full blown desktop apps (not toy/phone-like/game apps, that can live in one space only) with no integration/entry points inside modern ui. Or maybe they want to participate in that "kill full-blown desktop apps" movement ?
So is there a model for a desktop app developped in whatever GUI toolkit, that wants to have some minimal integration with a small HTML/CSS/JS frontend in modern ui, like for e.g providing a dashboard of favorite or recently accessed files, contacts, etc ?
Your first statement of "only in a browser" is not correct. Desktop applications don't change their current design paradigms. You can have browser-based apps on the desktop, of course. But full clients are still supported and still viable as a real solution to problems.
Your takeaway from that comment should be that desktop applications are not deprecated as people assert. The reality is, desktop applications are still the only solutions to many problems.
Your second question of shared data is not correct. Skype shares lots of data with its app companion. Not because of shared local storage, however; it is because of the services that it shares. My account and contacts are on the server. So, they share a lot.
Your takeaway from that comment should be that Windows 8 apps should not highly leverage local storage but should be built as service-oriented clients. To that end, your desktop applications should have already started to leverage this architecture, too.
Your third question (which is very cryptic) seems to be asking if a desktop application and a companion Windows 8 app can share or integrate with each other. The answer is yes. Not only can they share the same service, but file associates, custom protocols, and some of the non-Store manifest capabilities allow for this explicitly. Line of business applications should have a companion app, if you ask me. The integration points are many - though not every. But there is no other way to leverage the new capabilities of Windows 8 without introducing a companion app - even if that app does very little.
Your takeaway from that comment should be that Windows desktop applications and companion Windows apps are the preferred and anticipated development approach.
Best of luck, thanks for the question.
I'm looking for a way to allow potential customers to try my application before they buy it.
The product is a windows forms application that requires an SQL Server database to operate.
Although I have a functional demo that the customer can install on their network, I want to make it easier for them by have them "play" with it at my environment.
I remember Microsoft had (has?) something similar. I was testing Visual Studio a few years ago in a virtual environment where I was connecting to a server at Microsoft.
They setup the environment this way so when a user logs off after using it rollback his actions. Or to explain it better: when a user logins it starts with a new, clean environment.
So any projects I've created testing Visual Studio were lost after I logged off.
Any suggestions?
Thanks.
Some solutions that come to mind:
Provide remote access
You could provide access to a running instance of your application via some sort of remote connection protocol, e.g. via RDP or via VNC.
For example, there is a Java VNC client which can run as a Java applet; you could put that on a webpage and have it connect to a VNC session you host on your servers.
Or use Windows Terminal Server, and allow connection via RDP.
Both solutions of course have the drawback that people need to open the appropriate ports, if they are behind a firewall. There might be ways around that, however (e.g. you can run VNC over HTTP).
VM image
A completely different solution: Provide a ready-to-run VM image (for VMWare, VirtualBox or similar) of your application, including server and everything. You would need a demo version of your app though, plus getting redistribution rights for all the proprietary components (Windows OS, SQL server) might get hairy.
Offer videos
Often people do not really need to actually use the app; they are mainly interested to see how it works. So maybe it is enough to host videos of the app in operation. That allows you to put in some advertising for your features, and lets you show the users what they might miss when testing on their own.
Does anyone know of an open source web service/wcf service that can stream media content to clients? In particular I am looking for something that could access my music collection and stream it to a client (could be a client browser, win mobile app or even iphone application).
I guess it would have to be WCF based as I'm not sure that webservices do streaming really well. Also Windows Media Streaming Services is not the best way to go as the service should operate from a vista/xp machine (preferably).
If not, does anyone know the best way to start going about creating something like this - I'm not sure I know where to start with this one, although I can see many many uses for such a service!
Even though it's not open source, Windows Server 2008 has a Streaming Media role that will do what you ask. Of course, you'll need to have a server to put it on.
I tried Orb and it is quite good, apart from the fact that it hijacked my tuner card so media center would no longer work. However I'm going to try and create a home grown version.
Orb (www.orb.com) will stream your media to just about anything with a web browser. I've been running it on an XP virtual machine for about a year. I love being able to stream my entire media collection to my phone while I'm working at a client's site.
While it isn't open source, it is free and relatively well supported. One of the best features is that the architecture is set up so that there are no special requirements for your firewall -- it just works.
