I am new to GDbus programming. I need to implement a simple Dbus send-receive message (Signals) using Dbus Glib. I tried to google some sample programs, but couldn't find.
Can anyone post any such sample program or point me to some sample program tutorial?
Thanks in advance...
Thanks,
SB
I think following these steps could help:
Read the wikipedia article on DBus to get a good understanding
of the DBus architecture.
Follow it up with these slides(atleast the first few slides about the architecture). Here is the original GNOME conference video where these slides were used.
Look at a simple hello world program using GDBus here, or for something more detailed, see my example code here. I've got a detailed README explaining the details.
This should help.
:)
I've found this tutorial helpful. It starts off explaining DBus in general and continues with showing implementation examples using gdbus.
I found a book that talks about GDBus, gdbus-code gen, GVariant and all the relevant bits and pieces:
http://maemo.org/maemo_training_material/maemo4.x/html/maemo_Platform_Development_Chinook/
Simple server/client example:
https://github.com/chiehmin/gdbus_test
As outlined above, I would start with the wiki article to understand the concepts:
https://en.wikipedia.org/wiki/D-Bus

I'm intending to develop a new OF for RPL in cooja simulator, the thing is that I don't find any tutorial or example on how to do so!
Also, There are hundreds of published papers on this work, yet no guidance on how to conduct your own experiements!
Any help or tutorial i can follow.
Furthermore, i need to know what are possible tools needed to do so, like matlab, python or C++ libraries?
too much confused and cannot figure out where to start actually.
Please Help
Please Help I have been searching and reading alot, nothing found but journal papers discusses things theoritically.
I'm Alexander Mashkovtsev, student of gymnasium "Akademy", Kyiv, Ukrane. I'm 15.
I'd like to do face recognition program using OpenCV.
I write science work about face recognition, too.
It's very interesting for me, so i search a command.
I'd like to demonstrate the work on Kyiv High-Technology Center to get help with this.
There are people who are ready help me to create this program?
I will be grateful. Also ready to to reward the person who will help me.
Thanks!
have a look at the opencv facereco docs
or, here for a small python demo (yea, i 've seen your other questions here, that's why i'm posting the latter).
but ofc, you want to write your own, if i understood that right, that's great!
It seems that Face++ SDKs are more easier than OpenCV.
You can refer to Face++ website, look through their API docs overview.
Good luck!
I recently watched great google talks speech about Cling - C++ language interpreter. But I wonder if anyone except people at CERN (where it is developed) are using Cling, and how good it is from non-collider-physics-scientist point of view, can you write desktop apps with it?
There are some videos of uses cases different from the High Energy Physics: http://www.youtube.com/results?search_query=cling+c%2B%2B (I think first couple are the relevant ones)
It has the potential to be very useful, but it is very young. There is no documentation that I could find, no dedicated mailing list, no online tutorials. I was able to get small toy code to run, but couldn't figure out how to use it productively on a large library yet.
Cling project is well established one. You can find more information in their official website cling. They also have a forum
Thanks
I have been running in and out of OpenCV 2.4.3 trying to figure out the extra functions and parameters that can be used to CvBGCodeBookModel based background subtraction. The documentation is not very helpful, does anyone know a resource/tutorial out there that explains CvBGCodeBookModel implemented in OpenCV along with some of its functions?
Guidance much appreciated
There is a sample in the opencv code (samples/c/bgfg_codebook.cpp) that uses CvBGCodeBookModel, it might be a good place to look.
It says the code is adapted from the book "Learning OpenCV" by O'Reilly press, so that would be another resource.
There is also this paper that describes the theory, not sure if that would be helpful to you or not.
I have started working on Corona SDK.As you all know it uses Lua as the programming language,i wanted to know some good links or ebooks which i can refer to begin development.I am an iPhone developer and working on objective C since last 1 year.
Any suggestions,help would be appreciated.
Thanks

I've been using this: Programming in Lua, first edition (FREE online edition of the book)
The Corona SDK forums are also good for specific issues related to the SDk itself. It seems it is having a few database problems just right now, but you might want to check it later.
Edit: just for completeness, here is the link to the Lua Bookstore # amazon (not an affiliate link).
You can also check out http://learningcorona.com/ which has a huge listing of tutorials for Corona.
Here's a great resource for learning Lua, it's aimed towards beginner programmers (doesn't sound like you), but it does a great job at introducing Lua and most of the basic concepts:
Lua for Beginners:
http://lua.gts-stolberg.de/en/index.php?uml=1
That, as well as the "Learning Corona" section of the Ansca docs should be plenty enough to get you up to speed in a very short amount of time:
http://developer.anscamobile.com/resources/docs/
TIP: Start working on a project, or converting an existing app using Corona and you'll learn it blazing fast! That's what I did, and I learned it quickly enough to have one of my games fully converted in about 8 days.
For understanding basics of CORONA SDK I will prefer "Corona.SDK.Mobile.Game.Development.Beginners.Guide"
book from Packtpub publication.
and You can also check out http://www.learningcorona.com/ for tutorial both video and audio.
The Lua Reference Manual is also an excellent read: Concise and complete.
Lua Gems is also worth looking at (at least the freely available snippets).
I found the Beginning Lua Programming book to be pretty good as a complete reference for Lua with good example code.
My very personal advice is just take a look at great books (Programming in LUA is covering everything) and switch as soon as possibles to samples / tutorials in order to learn all the API functions.
There are several Corona sdk video tutorials on YouTube. One demonstrates how to create a simple balloon game in a few minutes. You can have Your Lua editor in one window and YouTube in another, and click on the video to start/stop and switch to the editor and type in the code. Some tutorials provide links to download the code.
hello you can use their website they have good documentation you will find it here
