Since the online documentation is somewhat hard to come by, this is a short tutorial on how to download and work with source RPM files in CentOS 5.5. And by "work with," I don't necessarily mean compiling and installing; you might simply be interested in examining the source code for one of your CentOS packages, and we'll show you how to do just that.
We're aware of the time and budget pressures at most companies, normally accompanied by the plaintive cry from management of, "Yes, I know we need training on that topic, but I just can't afford to send my entire team away for three (or four or five) days to get it!" And that's where we come in.
The main focus at Crashcourse is to offer a choice of intense, 1-day, hands-on courses on specific topics in Linux and open source. And given that we already have the laptops for the delivery of that training, the idea is to show up early, set up a classroom, then spend the day teaching exactly the topic you're interested in. No travel time, and no wasted classroom time.
If we don't already have a course that addresses the topic you're interested in, drop us a note and we'll see what we can do -- our content providers can almost certainly put together a course that's precisely what you're after.
While there are a variety of sources for Linux and open source training, we at Crashcourse are taking a slightly different approach. Our philosophy is simple: exactly the training you want, and no wasted time or travel to get it.
