WEEK13 Ubuntu and Kali

    Over the years many different operating systems have been developed on the base of Linux. Due to its moldability the individual systems are tailored to a certain user-group and thus for a certain set of tasks. Distributions vary from versions for office users to systems for super computers, the range covers all aspects of operating systems. One of the more known systems are Ubuntu and Kali. Whilst Ubuntu focuses on Linux starters, offering a clean user interface and complementary applications such as LibreOffice, media players and browsers, Kali was designed for offensive cybersecurity. It has pre-installed tools that were developed for penetration testing and ethical hacking.

    Kali is being developed by only a small team; thus, they concentrate on the cybersecurity specifications and use an existing operating system as a base. In 2010 and 2011 they used Ubuntu as their base, they since have changed to Debian and kept it. Ubuntu, which was also initiated in 2004, is developed by a community worldwide, with thousands of enthusiasts and experts having contributed to its growth over its lifetime. Its founder Mark Shuttleworth had the mission of creating a social and economic operating system. Social in the sense that it is free and available to everybody and in the economic sense to reduce costs of “professional services”. Differently Kali’s founders, Mati Aharoni and Devon Kearns, designed their software for Kernel Auditing, which is also the origin of its name “KA Linux”, or Kali. The first Kali-version was released in 2013 although the project started much earlier in 2004, with other published versions predating the Kali system, such as Whoppix and BackTrack.

    The basic idea of Linux is to create a free and open-source system that users can develop and modify to their needs, which is also implemented by both parent companies to the systems, Canonical (Ubuntu) and Offensive Security (Kali). The users are allowed to redistribute the product as long as no changes have been made or make changes to the individual version. Both Kali and Ubuntu are run with the GNU General Public License, although some elements of Ubuntu are also open source. This gives their users many freedoms allowing the goal of Linux to prevail. Without effective operating systems such as Ubuntu or Debian more specific software such as Kali would face larger hurdles to achieve their goals.

Linux offers its users and developers a unique opportunity to create a system tailored to specific needs. Through the licenses protecting its free use and companies and individuals increasingly creating higher quality software, a large variety of effective tools is brought into existence. Ubuntu and Kali are just two of the hundreds of products, that show the variety and potential of Linux distributions.

WEEK11 Part1 Censorship: Who should censor?

       Censorship is a strongly debated topic, whilst some states used it to control the content their citizens can access, limiting their rights and freedoms, some institutions argue that their censorship protects its networks users. One example are libraries or educational institutions, especially schools censor certain websites such as gaming website, adult websites and possibly others. Some are blocked with the argument that they should not be accessed by children and for certain websites it’s the distraction that is a factor.      At our school initially YouTube was blocked which teachers very quickly recognized as a problem as our school was digitally proactive and incorporated online resources into everyday class. Multiple other websites were taken off the ban, however the school office was reluctant to remove the ban completely. Teachers and staff were provided with a separate internet connection so that they were not required to circumvent any security measures. However, whe

WEEK14 Neck-muscles from Typing - Paul Alexander

     In 1952 the six-year-old Paul Alexander becomes ill and soon is diagnosed with Polio. The chances are slim but he manages to survive, not without losing his mobility and physical freedom. Since then Alexander has been confined to the range of his “iron lung”. The iron long keeps his vital organs alive, but requires large amounts of energy and technical thus making a normal life extremely difficult. Alexander is immobilized from the neck down, however learned to use different tools with his mouth to draw, type or control other elements.      Alexander worked hard to learn to breathe without his iron lung. For the first three seconds he needed almost a year of practice, but he was tenacious and wanted to explore the yard, then the streets and after completing his studies he managed to appear in court as a lawyer for hours at end.      In 1967 Alexander succeeded in completing high school without ever attending class and went on to study law at the University of Texas (Austin).

WEEK11 Part 2 Privacy: What if we know what they know?

     Another disputed topic is online privacy, should we have complete privacy? It is a very complicated discussion as the counter argument is strong. Complete privacy also ensures a high degree of anonymity therefore making it more difficult for law enforcement to identify criminals or other wrong doers. However, an individual with no intentions of criminal activity will feel wrongfully treated.      The NSA and other security agencies run security checks on specific words, phrases and activities on certain websites. If the words “bomb”, “how to build a weapon” etc. are searched the user will most probably be registered by their system. In such cases I would agree that an increased interest in such topics should be monitored as they could pose a certain threat, but as somebody that studies engineering and is sometimes merely interested in knowing how things work and the science behind certain technologies, I feel uncomfortable doing research on such topics. Furthermore, investigativ
