"Over the last couple days, I implemented a generic tower of compilers in Guile.So for example, you have Scheme as a source language, which defines a compiler to GHIL (a scheme-like intermediate language, simpler and without macros), which defines a compiler to GLIL (a lower-level language), which defines a compiler to object code (the byte sequence of VM code)..." -- see also

There is a plethora of free software available in the open source community. Problem is, you have to learn how to compile it from source code if you want to use it. This nifty article will walk you through the steps...

On Tuesday, the LLVM team announced the availability of its 2.7 release. LLVM is an open source project with a license similar to BSD's; it offers front ends for a number of programming languages, compiling them to intermediate code that can be interpreted by a Just-in-Time compiler or immediately compiled into native code.

"A co-worker recommended GNU Global for browsing source code a few days ago. It was pretty easy to set up. Install it and then go to the root of your source tree and type gtags. Then you can run global on the command line and try it out. Try things like..."

A New Zealand high school running entirely on open source software has slashed its server requirements by a factor of almost 50, despite a government deal mandating the use of Microsoft software in all schools.

Applications can create a lot of temporary files sometimes, and these files aren’t always cleaned up automatically. An example of this is when you run Python applications. Particularly if you’re a Python developer, your source code directories stack up with a .pyc version of each file, which is the cached compiled copy of the script.

I am personally a strong advocate of using the Command Line. However, I am coming from a more tech type of situation than some others do. For the 'average" user however, is the Command Line relevant to everyday use?

I started learning computers back when DOS was all that was available to me, so I was comfortable with the command line. When Windows 95 was released my command line usage dropped considerably because there simply wasn't the "need" for it that there once was. I've gone from using the command line all the time to using it very seldom because GUI's were getting better and becoming more wide spread.

Today’s “Newbie Tip” is learning some basics about the “Command Line Interface” or as it’s mostly referred to, “Command Line”. The command line gives the user the ability to interact with the operating system by typing via a text terminal.
