I need an open source online video chat as an independent service on our server, I found jitsi.org but apparently it only runs on the jitsi's servers, I'm not sure so I'm asking that doe's any one know about it or doe's any one know another open source service to implement video chat/conference?
You can run it on your own servers too. Just follow the installation instructions: https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md and you should be able to get it running in no time.
Disclaimer: I work on Jitsi.

The question is pretty clear I think, but I will elaborate on why I'm asking it.
I created a little blog engine based on OneNote. Basically, the blog configuration asks for an access to OneNote. Then the user chooses a section under which the blog posts are stored.
There is a cron script that will use all these informations to automatically get new pages, fetch the medias and cache every, and finally display the posts.
I chose OneNote because I own three Windows 8 computers and a Windows Phone, so OneNote was an easy choice, as I didn't want to get an other application to manage my blog.
There is still a lot to do (as always with softwares...), but I want to make this more or less an open source project, so that other people can install it on their websites and link it directely to OneNote.
The only "big" obstacle for this now is that authentication in the OneNote API needs to register the application on the Live Connect, and specify a redirect domain. So every user wishing to use this blog engine on their server will have to register their own application... That will look complicated just for a blog, especially if you're not tech-savvy.
Is there a way to "skip" or work around this requirement, even if it requires the user to make the section public (as it is for a blog, this doesn't seem too much to ask) ?
Thank you in advance,
Cheers
Sounds like an awesome project! When you get it released be sure to let us know at #OneNoteDev.
Unfortunately, at this time there's no way to circumvent the requirement for Live Connect OAuth configuration. You could offer a hosted variant so only you need to worry about the LiveID configuration.
I am trying to figure out a way to do an internet connectivity check for an AIR for iOS app. Previously, I was using (against my better judgement) a URLMonitor that checked Google once every 30 seconds. I did not like putting that load onto Google and neither did they; this morning, our network got flagged as a possible DDoS attacker simply from testing the app. So I had to disable this type of check and move on.
I have thought about using the NetworkInfo ANE from Adobe, but that presents its own issues in determining internet connectivity. The only way I can think of doing it is to check for interfaces "en0" and "pdpxx" (which correspond to WiFi and Cellular interfaces, respectively) and check their IPs to ensure they are not in the 192.168.x.x, 10.10.x.x, or 127.0.x.x ranges. However, I am not entirely sure those are the only static router/localhost IPs out there and there is always the possibility that the network interface names will change in the future, which would render this monitor useless. There is also the issue of IPv6 possibly throwing a wrench into this method as well.
Is there another way to check if the user is connected to the internet? I've searched multiple times and it seems that these are the only two ways to check. If that is the case, what is the best way to check?
I'm surprised that you got flagged as a DDoS attacker, are you sure that's what happened?
In any case, if your not happy with putting the load onto someone else's server, then make your own server, just a basic setup that you use with the URLMonitor. You don't have to use google's url with the URLMonitor, you can pass it another URLRequest, which could point to your own server.
monitor = new URLMonitor(new URLRequest("http://www.you-own-server.com"));
This might also be useful if you decide that you want to pass more data between the app and the server. It's your server, so can do what you want with it.
I don't think there's any other way to check if the user is connected to the internet. To be honest, I don't see why there would be. Checking for the users interfaces/wan0 etc... probably would be possible, but you'd need another program, maybe a simple python or c++ program, that Air could use to check these things, but that sounds like the long way round.
A web page is not loading/hanging. How will you debug it?
I have been asked this question couple of times during my telephonic interviews. But I don't know the perfect answer.
I had given answers such as checking if the web-app is deployed properly, the internet itself might be slow, the JSP might have some errors, checking logs for any such detail, etc. But interviewer kept asking "These are all good checks, but what if all of these are fine, what else might be wrong?"
Also, it is not a JavaScript specific question. I can debug the JS/jQuery code using debugger, or following the console.log(). But how will you debug a plain JSP page?
Can any web-application gurus at SO help?
Once you know that you can't simply get to your site in the expected way (what I call the Hail Mary Test), then you need to start from the inside out.
Because of the multiple failure points a website can have, I always create a command line environment that allows me to test the framework & DB operation independently of the web server, firewall settings, etc. This can take some fiddling depending on what you are using, but I've done this successfully with Django, WordPress, Drupal, etc.
Once I know the app itself is working, I connect with a command line client (e.g. links) to see if a client coming from localhost works as expected. This confirms that the server itself is working (at least partially). Then I test from another host on the same LAN. More than once I've seen localhost work and LAN access not work, and the problem is almost always server configuration or firewall configuration.
If all of that works, but you still can't get to your site from the internet, then it is a networking / firewall setting somewhere further up the food chain. Try to find a host that is one step farther up from where you last succeeded and test that. Lather, rinse, repeat.
Battlelog was released by EA alongside Battlefield 3 recently, and I'm curious how it is able to launch games, such as Battlefield 3, from a web browser?
More generally, how does a website launch programs locally?
I'm one of the developer responsible for the launch part of Battlelog. It's handled by a combination of the installed web browser plugin and JavaScript. Launching the game basically goes through these steps.
We figure out where you've installed the BF3.exe by using a registry key
We use the plugin to launch that exe with a couple of command line options
When the game client has launched, it opens a connection back to the plugin, for two-way communication between Battlelog and the game.
Game client sends state info and error messages back through the connection, so we can show progress and errors in Battlelog, and also know when the game has closed down.
It is thanks to the plugin you installed at battlelog. Websites are not allowed to execute programs on your local machine due to the HUGE security risk that would present. Plugins have to be used if you want to accomplish virtually anything outside the context of the browser, which is why you have to explicitly give them permission to install when they try to run.
I think that there are two options. First, the link points to a file which has an extension understandable only to that program, like when you click a .pdf link a pdf viewer will open. My second guess is that the link may use another protocol associated to the program in question, does the link start really with http://?
Im almost 100% sure it uses the plugin you have to install to manage the launch process as it also controls whether the game is minimised or not.
I have an HTML5 site. I want to do following thing:
Walk through files in a folder
Find all images
Get exif file from images
Analyze an exifs (on server)
Correct bad exifs
This is a best scenario, that it can be. I am conscious that 1st and 2second step is possibly done only by selecting this files by user. And 5th step is possible only when the analysis will be done at user's machine. So what is the best way to do it (to get closer as much to the optimal scenario)? What should I use without need to force a user to install anything?
EDIT:
At least I have used free GeckoFX web browser as a basic desktop app. Interface is created in HTML+JS Thx all
You would need to create an application that runs on the computer of the user. You can't create an HTML5 site that does this.
A Chrome HTML5 webapp should be able to do this.
I'm actually looking at this in these days.
Here is a NOT WORKING example ( due to old API specs, I think)
http://benno.id.au/blog/2009/12/30/html5-fileapi-jpegmeta
But should at least give some good insights.
You should use ExifTool.
It is available as a Perl library here:
http://www.sno.phy.queensu.ca/~phil/exiftool/ExifTool.html
And also as a command-line tool which can be ran by the server (same site).
