Chromecast for digital signage - chromecast

I was hoping that someone with chromecast experience could help me with the following.
I want to make a simple digital signage application using chromecast. My plan is to set up a bunch of monitors with chromecast attached. Each monitor would point to a particular URL on the local network -- not a public facing web site. Each one would refresh its view every few minutes, completely replacing its content with the information on the web server.
I'd like to do this without mirroring, so that the chromecast itself would keep reloading the page without another device helping it along.
Can someone point me in the right direction?

Maybe start with the Chromecast developer guide: https://developers.google.com/cast/
From here you could choose to use the API here: https://developers.google.com/cast/docs/downloads
When you're ready to release it you probably need to register an API key with them for your sign app here: https://developers.google.com/cast/docs/registration
Good luck with your app.

From the sounds of it, Greenscreen.io would be perfect for this application. Especially when you're running a local server.
I want to do a similar digital signage app, but ended up needing to go for Raspberry Pi's with wifi that connect to a public webpage. I'd have preferred to use Chromecast for it though!

Why can't I access YouTube today? PR_END_OF_FILE_ERROR

I'm having no luck at all accessing Youtube today. I get this when I try to access http://youtube.com:
Secure Connection Failed
An error occurred during a connection to www.youtube.com. PR_END_OF_FILE_ERROR
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
I am using the current version of Firefox - it just auto-updated earlier this week - on Windows 10. I haven't had any problems with Youtube previously.
I thought it might be the specific video I was trying to watch or maybe our internet connection but my brother, who is in the same house with me and is using the same network (except that he connects with ethernet while I am on WiFi) has no trouble at all accessing YouTube and playing the exact same video I'm trying to watch.
This is not the first tab I've opened to try to access Youtube today. The first tab I opened is still there. It actually started playing the video but stopped just 4 seconds into the video and has been loading ever since, a couple of hours now.
I'm baffled by what could be happening here. We aren't using any kind of VPN or proxy server. Does anyone have any ideas?
I'm really not sure what tags to use for this problem....
Try making a new profile with about:profiles and set it to default.
If its working, export your bookmarks from the old profile and import them again to your new profile.
in other words try to synchronize the profiles through Mozilla Account
this link can guide you to do it

Using Airconsole on a standard University/Corporate network for dev

I tried to make an airconsole game at my university. Unfortunately like nearly all universities devices are not able to see each other on the network. That means I can't serve pages from my laptop to my phone. So, the standard
http://www.airconsole.com/#http://<myipaddress>:8080/game/
Does NOT work. This makes it impossible for university students and people at game jams at universities to make games for airconsole.
I even tried setting up a remote server at digital ocean, uploaded my code there and then using
http://www.airconsole.com/#http://<ipaddressofdroplet>:8080/game/
Even that didn't work. Since I was on a deadline (Global Game Jam 2016) eventually I just gave up.
Is there a workaround or is making games for airconsole on a typical university network just impossible?
You can use tools like https://ngrok.com/ to make your localhost public even if there is client isolation.
Let's say you are running your game on http://192.168.0.36:7842/ and http://192.168.0.36:7842/controller.html is not accessible from a your smartphone.
Then run the following command:
ngrok http 7842
This will output you something like
Tunnel Status online
Version 2.0.19/2.0.20
Web Interface http://127.0.0.1:4040
Forwarding http://8941ec1a.ngrok.io -> 192.168.0.36:7842
Forwarding https://8941ec1a.ngrok.io -> 192.168.0.36:7842
You can see that http://8941ec1a.ngrok.io now forwards to http://192.168.0.36:7842
Now start your browser on:
http://www.airconsole.com/#http://8941ec1a.ngrok.io/ and you should be able to connect your smartphone.
Note to Unity Developers: You need the latest airconsole unity plugin from www.github.com released on 2016-02-01 and you should select "Normal" as the browser start mode.

Run a canvas application locally

I am developing an MVC 3 Canvas app. Is it possible to debug locally rather than hosting it somewhere?
Thanks
I am developing some app in PHP at the moment, but I guess the language doesn't matter. Just set the app address to your local development address. The page is loaded in an iframe, so your computer maps it to whatever it thinks is the correct ip. Facebook doesn't care about where the page is hosted.
However, the communication of the API with facebook will be a bit slower than between Facebook and your production server. So don't worry if the App seems to be very slow.

Online server for desktop app - implement as web-server or custom socket application?

A bit of a generic question but let's say you have a desktop app that allows a user to connect to a central server and provides functionality like:
Login
Ability to auto-download profile data on login
Download and uploading save files through the app
A web-server (JSP/ASP.NET/PHP/etc) would do lots of work for you especially on the request-serving and threading front, but it seems a bit of a cheat for a desktop app to use HTTP requests like this.
All thoughts welcome. Maybe this should be community wiki?
If you want to leave things open for other possibilities in the future, go with a web server. That way, if you decide to write a web-based version of your desktop app (or an iPhone/Pre/Android application), you don't have to rewrite your socket server. Almost everything can speak HTTP these days.

Ad supported free WIFI based internet access point

We would like to setup a small Wifi access point where we provide free internet in and around our store, with store banner pop ups added to any web content they browse using this net connection. What do we need to do this? I am expecting some kind of C# solution, but I can live with Java too.
you could try CoovaAP. It provides support for dd-wrt routers, and it is fairly easy to use and configure. I'm using it successfully at home.
Most Wifi access points allow to control access with a Radius server on the backend. To add some additional content you might consider using deloradius in combination with CoovaChilli.
You can try Socifi - free public WiFi advertising and monetization platform.
