I just started using QWS. I am looking for more details about Qt Windowing System(QWS) but the resources are really few. I have read this one http://www.slideshare.net/qtbynokia/qt-on-real-time-operating-systems but I think it only covered few things. I would like to understand how the server and clients interact with each other and the other things that's happening in QWS. I hope someone could guide me. Thank you.

this might be a stupid question, but I couldn't find anything on the web.
I am wondering, how certain IoT devices sometimes make themselves available to the outside world, without me having to open any ports etc. on my Router.
For example: I connect my Phillips Hue Bridge to my Router and somehow if I activate it in the app, I can control it from anywhere.
How does this work? I am trying to build something similar, so thats why I'm asking.
If you dont understand what I mean let me know, maybe I can describe it a little bit better then.
Thanks in advance!
I've just discovered TideSDK and it seems to be a really great tool, but I have one requirement : I need to use some native code (for managing USB devices for example) and so I need communication between this native code and the web app, is such a thing possible with TideSDK?
Yes, working with native code in TideSDK is possible. Our SDK is modular and we have been reorganizing the code structurally to make it easier to do the sort of thing you want. At a modular level, you will be contending with support for multiple platforms typically.
A module should extend to all platforms that you are supporting. We expect to have documentation to help developers (familiar with native code) to better understand the SDK. This should include some module boilerplate to help you get started. At this point, we have yet to prepare this more detailed documentation. We have much to do and sometimes progress seems slow despite all the great efforts going into TideSDK.
TideSDK is a large and complex SDK but don't let this frighten you off. It is extensible and we will be shining light on this soon with module development guides. It would be cool to talk more on IRC about this with you so feel free to drop by at any time. Perhaps the functionality you are speaking of is of general use ie. to extend the APIs for everyone.
There are possibilities to work together with the core developers of TideSDK on modules and to contribute to this great open source project. Other possibilities also include sponsoring module development if this something that you need more immediately for a project. Hope this helps.
Now that the owner of ASIHTTPRequest is no longer working on the library, is there another alternative that is as good as this library?
Or maybe will the repository from their github be updated? By, maybe someone else who is well educated about the project (At least someone knowledgeable will still continue to work on it)
Thanks
If you look at https://github.com/pokeb/asi-http-request/commits/master you'll see that it has been updated since the owner stopped working on it...
I would recommend AFNetworking as the best supported option for a general networking library

If you are mainly working with a RESTful API, then RestKit is a great library to use instead of writing your own glue code:

I'm working on a large web project based on LAMP stack.
I have to create a 'look and feel standard' for the aplication and i don't know how to begin. What parts must have this standard? Is somewhere a model?
I don't have large experience on web development so maybe i need to inspire in some good standards. Do you know where can i find some standards?
Thank you very much :D
The jQuery UI ThemeRoller provides a great GUI for playing with their stock themes, or customizing them. Worth while investigating.
After reading a bit more about how Gnutella and other P2P networks function, I wanted to start my own peer-to-peer system. I went in thinking that I would find plenty of tutorials and language-agnostic guidelines which could be applied, however I was met with a vague simplistic overview.
I could only find very small, precise P2P code which didn't do much more than use client/server architecture on all users, which wasn't really what I was looking for. I wanted something like Gnutella, but there doesn't seem to be any articles out in the open for joining the network.
RFC 4981, with its huge bibliography, could be a very good starting point.
I had to write a basic Gnutella client in C# using Web Services and I think the class notes on the P2P stuff are still available here and here.
You might have better success researching Bittorrent, I believe that the creator has written some papers, and it seems others are as well.
BitTyrant
Bittorent.org, see the developers section
I don't know what platform you are trying to use, but here is a decent article on the subject for .NET.
I've found the TheoryOrg Unofficial BitTorrent Specification to be the best online source for Bittorrent information. Also, the Monotorrent code is fairly simple and easy to understand. There's also a project called "GCT" which implements JGroups style P2P for LAN/Multicast environments, and its code is similarly easy to understand (if a bit buggy).
You can try to read Gnutella2 and try to implement messaging. For reading conceptual material you can read Distributed Systems by Andrew Tannenbaum.
You can have a look at JXTA. It's intention was to be a generic, platform agnostic p2p framework, in contrast to other p2p implementations which are usually for a very specific purpose (such as Gnutella).
Don't be fooled by it's Java appearance, there are binding available for C/C++/C#, but the core protocols are implemented in XML which should translate to any language.
