Software Libre and Commercial Viability
Naturally, I'm aware that not every software package can easily be turned into free software. I'm not talking about office products—I'm confident some good projects will supply this need, sooner or later. Rather, I'm talking about all environments where a strong competition exists for a product only loosely based on its software component. For example, industrial equipment might include a computer and some commodity hardware (a robot, custom I/O peripherals, PLCs, etc.); the software application hosted in the computer is a minor part of the whole, but its features greatly affect the overall value of the equipment. Producing and debugging such applications usually require huge investments (preventing free redistribution of the source code), as a form of protection against competitors.
Another meaningful example is cell telephones. They include a lot of software and such software is the component that defines the overall capabilities of the device. However, this software is almost invisible to the end user, who perceives the device as a telephone and not a computer. Such software is strictly proprietary because of its major functional role in the device.
Unfortunately, I see no easy way to liberalize this type of code. Although I don't care too much about cell phones (I don't use them), I would prefer to see free industrial applications because their technological content is usually worth reusing and adapting to new problems.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
