Imagine not having access to a software's source code but still being able to understand how the software is implemented, find vulnerabilities in it, and—better yet—fix the bugs. All of this in binary form. It sounds like having superpowers, doesn't it? You, too, can possess such superpowers, and the GNU binary utilities (binutils) are a good starting point. The GNU binutils are a collection of binary tools that are installed by default on all Linux distributions. read more

When you hear the term open source, do you think this is synonymous with terms such as shareware, freeware, or public domain? If so, you are not alone. Many people, both within and without the technology industry, think of these terms as one and the same. This article illustrates how these terms are different and how open source is a transformative licensing and development model. Perhaps the best way to explore the differences will be to share my experience with software provided under one of the above models. read more

Then I'd move onto my working day and completely forget them, retaining only the well-known !! trick I learned when I first started using Bash. So most of them were never committed to memory. read more
