Have you ever thought to yourself, “gee, it would be a lot of fun to learn how to write software,” but you didn’t want to shell out money for books or a development environment? Perhaps you’re just curious, or maybe you aspire to be a developer one day. Whatever your reason, thanks to open source software and free documentation, you can pick up the skills required with no cost to you (other than your time, of course.)
Where to Learn
Before you start writing code and playing with a compiler (a program that translates human-readable programs into instructions the computer can understand), you’ll first need to learn a programming language. You could spend anywhere between $30 to $70 on a book. Or, you could instead go online. Not only can you use Google to find countless tutorials for just about any programming language, you can also find sites that offer free e-book versions of published works (for an extensive collection of books in any subject, including quite a few on programming, check out http://www.e-booksdirectory.com/). For most of your programming needs, you’ll find that buying books really isn’t necessary.
As you grow in skill, you’ll find that learning by example is a powerful tool. Fortunately, with open source software, you have a plethora of real world applications, their source code layed bare for all the world to see (source code is the human-readable version of a program.) If you want to look at the implementation of a text editor, for example, you can check out the source code for projects like vim (http://www.vim.org/), nano (http://www.nano-editor.org/) or emacs (http://www.gnu.org/software/emacs/). Do you want to know how various standard library functions are implemented in C, such as QuickSort? Then check out the source code to Glibc (http://www.gnu.org/software/libc/). Are you instead more interested in systems programming? Check out the kernel source trees for Linux (http://www.kernel.org) or FreeBSD (http://www.freebsd.org). You’ll find open source software for just about any need, from web browsers to mail clients, from 3D modeling to audio and video editing solutions. Whatever you want to look at, you’ll more than likely find examples written by others that can help you learn for your own projects.
Where to Get the Software
So, you already have at least some conception of what’s involved in programming, and you want to get your hands dirty by actually writing some code yourself. At the very least, you’ll need a text editor to write your code and a compiler or interpreter to run your programs. You may also desire a more elaborate solution, such as an IDE (integrated development environment), which offers you a one-stop solution for writing code and compiling/running your programs, all from the click of your mouse.
Either way, open source once again comes to the rescue. For C, C++ and a few other languages, you have the GNU Compiler collection (http://gcc.gnu.org/). There are also various interpreted languages, such as Ruby (http://www.ruby-lang.org), Python (http://www.python.org/) or Perl (http://www.perl.org/). If you’re looking for an IDE roughly like Microsoft Visual C++ or the like, you’ll find KDevelop (http://www.kdevelop.org), Eclipse (http://www.eclipse.org/) or NetBeans (http://www.netbeans.org/), among others.
For more advanced needs, such as revision control (a means of tracking changes in software), you have applications like Subversion (http://subversion.tigris.org/), Mercurial (http://www.selenic.com/mercurial/) and Git (http://www.git-scm.org/).
There are many more applications for a variety of needs, so whatever you’re looking for, give Google a spin.
It is possible to learn how to develop software without breaking the bank. With free documentation and open source software, you have all the tools you need to learn as little or as much as you want. Here at eRacks, we understand the needs of the developer, and can provide you with a machine pre-loaded with all the software you need to write professional programs.

We at eRacks are designing a new model geared specifically toward the developer, and want to hear from you, the customer, about what you would like to see in the system (please leave detailed comments for this blog post!)
We’ve been batting around a few ideas, both software and hardware related, and would like to share them here for your consideration.
1. IDE, Revision Control System and your Operating System of Choice
Our development model would (of course!) come pre-installed with the best in open source development-related software. Do you have a favorite IDE, or do you prefer to simply invoke your text editor, compiler and makefiles directly? Would you like us to install a revision control system such as CVS, Subversion, Mercurial or Git? What’s your operating system of choice? Are you a fan of Linux, FreeBSD, OpenBSD, NetBSD, OpenSolaris, etc.?
2. What Kind of Developer are you?
While there are usually at least some applications common to most developers, a great deal of the software you’d like to be installed will probably depend significantly on the kind of development you do. Are you a kernel developer? If so, we’ll install the kernel source and headers for you. Are you an applications developer? If so, are there any open source libraries you’d like us to pre-install for you? What about you web developers out there? We could, at your option, install a local web and database server for testing purposes, as well as your scripting engine of choice (PHP, Ruby, Python, Perl, etc.) Do you not fit exactly into any of these categories? Have we missed something? Let us know!
Do you prefer to develop on a laptop, or do you like to do your programming on a desktop machine? What would you think about having the option of two or more monitors to help you spread out your work, configured to your unique specifications (would you like 2 or more individual displays, or 2 or more monitors tied together into a single virtual display?)
Anything we haven’t mentioned that you’d love to see in a development-specific model? Again, just let us know! Be sure to leave us a comment sharing your thoughts.
