Week 6 - Computers and Laws II: Software and Content Licensing

-

 The idea behind copyleft is a general methodology of converting a program (or other work) into free software, not by a sense of money but a sense of rights. Copyleft has the opposite meaning of the term Copyright. In legal terms, Copyleft actually means sharing the rights recognized by the concept of Copyright with a contract, one of which is anonymous, instead of a contract between the parties. In this article, I am going to discuss 3 types of Copyleft - strong, weak and, no copyleft.


Strong copyleft - Even though it has some restrictions on developers, many people believe it is the best option for end-users. Software that has been made from the original must retain the license of the original work.


Weak copyleft - The main difference between weak copyleft and strong one is that weak copyleft allows developers to integrate the software with a proprietary system. It is mainly used in the case where a developer use collections of codes to make one software.


No copyleft - This is the option that gives the sense of largest freedom to developers as it does not limit licensing of the derivatives. There is basically no restriction. There is a possibility to derive extended applications out of it.

Week 13 - A Practical Example: the Story of Linux (Kali vs Parrot OS)

 Linux is the most well-known and widely used open-source operating system. Unlike other operating systems, Linux has an open-source structure. This means that the person using the operating system can be aware of almost everything that goes on in the background of the computer, and can organize and develop the operating system in his own way. Whether you know Linux or not, you've probably used Linux before, albeit unintentionally. Almost a third of websites are run by servers built by Linux. Apart from that, the Linux operating system is generally used by individuals who are familiar with software and many large companies. The reason companies choose Linux when setting up their servers is because it is much more secure than other operating systems. In addition, Linux is a more flexible and comfortable operating system compared to other operating systems. There is also an incredibly large community working to improve Linux. Companies can really get tremendous help from this communi...

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

 The main idea behind the book is to alter the idea of copyright legislation. In the first chapter, the writer begins the paragraph by denoting the fact that youngsters can be seen as criminals in the eyes of law because of copyrighted file sharing.  Living in the internet era, it does not seem possible to establish a rule or ban against file transferring between citizens. There is no technology to differentiate the copyrighted material and the private messages without revealing the information.  Another interesting scenario that the writer mention is that if people spend less money on purchasing CDs, they will spend the revenue to buy concert tickets which are more lucrative for artists than buying a CD. Furthermore, people in the past were not fully aware of the power of public libraries. Many people and authors were against public libraries because if people would use the same book without purchasing, the author could not earn money. However, it turned out that public ...

 In this forum, I will give my opinion on the book that was written by Pekka Himanen, Manual Castells, and Linus Torvalds. They come together to discuss hackers' working style, organization, work ethic, work urge, etc. To start with I will give some information about the writes. PEKKA HIMANEN: In her twenties, he received his Ph.D. in Philosophy from the University of Helsinki. His in-depth studies of the meaning of technological development put him in contact with academics, artists, government officials, and corporate executives. LINUS TORVALDS: While a student at the University of Helsinki in 1991, he created the Linux operating system, becoming one of the most respected hackers in the computing community. Since then, Linux has been used by thousands of users around the world.  MANUEL CASTELLS: Professor of sociology at the University of California, Berkeley. The critically acclaimed trilogy The Information Age, The City, and author of more than twenty books. I would like t...
