Building on the intro to version control systems in Emerging Tech Talk #24, in this episode Dan York describes how the Git distributed version control system is different from non-distributed version control systems such as CVS and SVN and then goes on to provide a very basic demonstration of using Git.

There’s obviously far more to using git than can be demonstrated in a short video here, so if you are interested in learning more there are many tutorials and other info available on the Git documentation page.

PRODUCTION NOTES: Question for viewers:

• Is the screencast of the terminal shell readable when you viewed the video?

After watching this, I think I needed to zoom in more so that the text was larger. I’m not sure how this would actually look in an iPhone, for instance. (I will look soon.) Something to remember for next time. Anyway, any feedback on how good or poor the viewing was would be appreciated.

And yes, I know the transition from me speaking to the screencast was a bit harsh… still working through some nuances of my tool chain.

For a variety of reasons that will soon become clear over on our Voxeo Developer’s Corner blog, I (Dan York) want to talk a bit about the Git distributed version control system and how it differs from non-distributed version control systems such as CVS and SVN.

Now wait a minute, you say, you aren’t a programmer, so why should you care?

Well, the reality is that I’ve used version control systems for writing books… developing courseware… for web sites… for configuration files… even for home directories of users. Basically, any time I have had a group of files where I want to track revisions to those files – or have wanted to collaborate with someone else and have a solid history of what changes we each have made. Once you start using a version control system, it is simply amazing the number of uses you have for them (only some of which might actually involve programming).

Anyway, “traditional” version control systems (also sometimes called “source code management” (SCM) systems, although there are nuances in the naming) such as the open source Concurrent Versions System (CVS), Subversion (SVN) and the many commercial equivalents all more or less use the model of having a central server from which users “check out” files and then “check in” (or “commit”) any changes they make back to the central server. In more recent years, distributed version control systems (DVCS) have emerged that fundamentally change the paradigm for how a user interacts with their information. Several new open source DVCS’ have emerged, including darcs, mercurial, bazaar and git. For several reasons, I’m currently working with git, but most of what I cover in this and the next episode are similar across the various DVCS systems.

In this first of three episodes I talk about version control systems in general and the different components that make up such a system. I discuss repositories, working copies as well as concepts such as branching and merging – and then wrap up with a few of the issues associated with traditional systems such as CVS and SVN that git sets out to solve.

At ITEXPO East 2009 in Miami, FL, host Dan York interviewed Irv Shapiro, CEO of IfByPhone ( http://www.ifbyphone.com ) about how his service makes it easy for developers to create voice applications. He talks about three application examples and also three magic ingredients, one of which is Asterisk and one of which is Voxeo’s Prophecy. He also invited developers to sign up for a free developer account at http://www.phonemashup.com/

The whole subject of “billing” is probably, for the majority of us, one of the least exciting and least sexy parts of the entire communications infrastructure. Yet it is probably one of the most *critical* aspects as that is how, ultimately, we all keep the lights on.

In this episode, host Dan York speaks with Jim Dalton, CEO of Transnexus ( http://www.transnexus.com/ ) and one of the leading proponents of the Open Settlement Protocol (OSP), an open standard for service providers and enterprises to exchange billing information among themselves. Jim gave a presentation at IT EXPO East 2009 in Miami and Dan caught up with him after the talk to ask him some questions. More information about OSP can be found at http://en.wikipedia.org/wiki/Open_settlement_protocol or http://www.etsi.org/

UPDATE: The white paper upon which Jim based his ITEXPO presentation is available online: “Peer to Peer Settlement for Next Generation IP Networks”
