As part of an amateur radio project I put together a network of video cameras and phones. 3 Raspian pis, one Arch pi, one raspbx (raspian). The pis with cams run olsrd to do mesh networking. The point of the test was to zero in on video performance across the mesh.
[personal note] This offers an interesting set of tools for a developer to create extensions, which are claimed to be first class citizens within the wave. It's reassuring that there is mention of how development has not kept to the standard API's but is mostly compatible with them. This may either mean a forking away from standards in the future,
Here is the bundle of stuff that was presented at the November meeting including the step by step PDF. See attached file.
If you are familiar with object-oriented programming, then you'll find Obejctive-C classes to be an easy concept to grasp. Each language has a different way of handling objects and object classes, any particular language may not support all features, but the base concepts are all similar.

I've posted a book on the site that will show you how to quickly set up IUP on your Linux box.
There are thousands upon thousands of homeowners right now that are desperately trying to sell their homes. Many homes need extra work done to them in order to strengthen their value but for financial reasons families cannot make the necessary upgrades to their homes.

There is already a plethora of foreclosures in the US market so it is to the homeowners benefit to take advantage of government grant money so you can hopefully sell your home.
The first thing you need is to set up your build environment. For most of these examples, you can use any OS that supports GCC. If you're running on Mac OS X, install the development tools and you're done. For Ubuntu or Fedora, install the appropriate compiler packages and any dependencies. On Ubuntu, the build-essential package works well. For Fedora, install the Developer Tools grouplist and the gcc-objc package.
You'll also need the Foundation framework libraries and headers. Ubuntu keeps these in the libgnustep-base and libgnustep-base-dev packages. Fedora calls it gnustep-base-devel. Fedora also requires the gcc-objc package on top of the Developers Tools grouplist.
If you already know 'C', then you have a good basis for Objective-C. As the name implies, Objective-C is an extension of C, much like C++ is. Here is our first example source file example1.m:
In the spring I did a NovaLug presentation on LVM. The attached power-point gives an overview of how LVM is constructed and how to use the basic features of LVM.
