Computers and Laws II: Software and Content Licensing (Week 6)

 

Most people are familiar with the term Copyright which describes the rights of creators that they have over their content. On the other hand, the term Copyleft, also widely known in the open source community, is a practice to make a copyright content redistributable and open source again. There are different methods and levels of Copyleft content and in this week's blog we are going to take a brief look at them.



Strong Copyleft - Strong Copyleft conditions state that if a content includes some of your code, it still should be redistributed under the name of your license, if at all.


Weak Copyleft - However, under Weak Copyleft conditions, if a product contains some of your code, some parts of it should be published and redistributed under your license, but some parts can be distributed under other licenses as well. Even if the finished product is the modified version of your code and serves the same purpose.


No Copyleft -  As the name suggest No Copyleft conditions do not limit the redistribution of changed/modified software, and it can be released as an exclusive version of the code.

Computers and Laws I: Can Property Be Intellectual? (Week 5)

 In todays' week we are going to talk about the second chapter of a book by  Rick Falkvinge and Christian Engström : The Case For Copyright Reform. Chapter 2: A Constructive Proposal For Copyright Reform The book states that the Pirate Party's intention is to not abolish copyright completely, but free it for non-commercial purposes. It is mentioned as an urgent reform due to today's non-commercial copyright standards threatening peoples' rights such as private communication and freedom of information. Sharing a file is basically two private individuals communicating and sending each other binary code, so the only way to limit the usage or to imply copyright would be to go through all those individual messages and verifying the content is copyright-free.

A Practical Example: the Story of Linux (Week 13)

  "LINUX AND HIS FRIENDS" As I am utilizing Windows as my "daily driver" I might not be as experienced in Linux as many other IT specialists, but in this week's blog we will cover two major distributions of Linux and the differences between them in my humble opinion. Desktop Environments: Both Ubuntu and Fedora utilize GNOME desktop environments by default, there is only a slight difference Fedora:  Fedora uses the stock GNOME interface Ubuntu:  Ubuntu has customized its GNOME interface to look more like the old "Unity Desktop"  Hardware Support: Linux as a whole has its fair share of driver issues and incompatibilities and both Ubuntu and Fedora suffer from that. However, Ubuntu: Provides an easier way to install necessary proprietary drivers which results in a more user friendly interface and better hardware support Fedora: Fedora on the other hand chooses to stick to open source software, thus making it challenging to update/install drivers Windows
