I want to connect a linux PC with HDMI output to my (Samsung) TV.
This allows to show a screen on the TV.
How can I use the TV's remote as an input device, sent over HDMI to control the PC?
Or in other words, can I make a simple user interface which is shown on the TV and is controlled with the remote control?
I mainly imagine using the 4 arrow-buttons and the OK to navigate and choose stuff.
Any links to doc or libraries (Java preferred) are welcome.
The protocol used to send the remote control signals is called CEC. In order to make use of it you will need hardware which supports it, and have drivers for that hardware.
Lacking any more specific information about the hardware you are using, I suggest starting at this page about CEC support on the Raspberry Pi

How can I turn WiFi on and off programmatically and change network (WiFi) in the Mac SDK?
CoreWLAN Framework seems to fit your needs. There is even a sample code named CoreWLANWirelessManager
The CoreWLANWirelessManager application utilizes the CoreWLAN
framework, which is the Objective-C public API for the Mac OS X IEEE
802.11 wireless interface. It gives developers an example of how to use the CoreWLAN API and exercises the functionality that the
framework provides.This functionality includes scanning for networks,
querying the wireless interface for static and dynamic parameters,
toggling interface power, changing channels, association, and
accessing the corresponding system configuration preferences for the
given interface.
You can change most WiFi settings using the networksetup(8) command (see the -setairportpower and -setairportnetwork options).
As for a programmatic API for adjusting WiFi settings, there is the CoreWLAN framework mentioned by Antoine.

I want to develop a socket based chatting app in Titanium compatible with Android, iPhone and Blackberry.
Please give me suggestion about it
If you want a "socket based chatting app", then you've already made decisions about the implementation, and so you really just need to know the interface for implementing it. Try reading the fantastic manual, it is very detailed on how to use sockets.
http://docs.appcelerator.com/titanium/3.0/#!/api/Titanium.Network.Socket.TCP
You'll need to roll your own server side to accept the socket connections, and your own protocol for the communications. Or adhere to an existing protocol.
Or you can use the existing, working Ti.Cloud sample I created. It is the Titanium specific version of what Hini linked at nodeacs.cloud.appcelerator.com --
https://github.com/appcelerator-modules/ti.cloud/tree/master/commonjs/example/windows/chats
You can use Titanium along with Node ACS to create the application.
Here is a sample chat application tutorial. I hope it helps you.

i would like make a simple application on iphone had a client and server
the app should let me send update from client to server and send update from server to client
the Question is... what should i read about to learn the major and important thing to start doing this application.
Check out gamekit. Connecting to the game network will allow your apps to talk to each other sending small data packets back and forth.
http://imagineric.ericd.net/2011/04/20/ios-gamekit-iphone-to-iphone-communication/
or you can use a TCP socket setup and communicate that way.

If the ios devices are on the same network it can work from one to the other.
If they are on other networks you will need a central server.

My question is regarding GPS.
Is there a way to locate a phone number using gps? Without installing any apps to their cell phone.
I am interested in both Windows Mobile and iPhone. But please do include generic replies also.
No, you can't.
You see, GPS and phones are two completely disparate technologies - nevermind that there are some multi-function devices (e.g. smartphones) which contain both. There is no generic way to connect one to the other that would work on all devices without custom software (i.e. without installing your app).
That said, you could create an app which checks the GPS location of the device it's on, checks the device's phone number, and reports this pair back to you over some kind of network connection (GPRS, 3G, WiFi, carrier pigeon, what-have-you). You'd need to update the GPS position from time to time as it changes, whereas the phone number tends to stay the same.
You'll need to use some kind of data channel as GPS is an unidirectional broadcast protocol (it's receive-only, there is no way to send a message through it).
Note also that you'll need the user's permission and cooperation in installing the app - firstly, the app won't install by itself as most devices have safeguards preventing automatic installs; and second, installing software without permission could land you in legal trouble (unauthorized access and all that).

I am trying to figure out how to capture the audio from a given software running on a mac, just like audio hijack does.
I'm aware that this is not the first question on the subject, but I'd like to better understand the possibilities on how to do it.
Crete a user space driver is the only solution to achieve it?
The best way that I've found is to get soundflower from cycling74.com. This basically gives your computer an internal interface that you can route to audio programs. If you then get a DAW like audacity you can choose soundflower as your audio input, set soundflower as your system audio output and record audio directly into your DAW.
