Teema 2 - Arpanetist Facebookini - Interneti kujunemislugu

     As it's been already said: the world of IT software and hardware is quickly developing. Some projects become permanent in our life, others fall and being memorized only in history books.

     And here we are to find out about two interesting pieces of "old" IT world.


The old, but still worthy: e-mail.

 

    It is hard to believe, but e-mail is already ~55 years old, and we still use it in our everyday life, despite popularity of online messangers such as Viber or WhatsApp. 

    It is believed that first e-mail letters were sent in 1965, when workers of Massachusetts Institute of Technology (shortly - MIT) wrote program "mail" for operational system CTSS, installed on computer IBM 7090/7094.

    Common sense of e-mail is absolutely similar with usual mail: you write someone a letter or packing some small parcel (in e-mail case: pictures, music files, short video, etc) and send it to anyone by their mail address. When they get your letter or parcel, they can do with it whatever they want, as it is now on their side.

    Using e-mail instead of usual mail for correspondence or communication with friends became much more comfortable and reliable. Nowadays, it takes for about several seconds to deliver an electronic text letter to anyone on the web, while usual paper letters can be on their way for weeks, and moreover, paper letter can be easily corrupted.


The forgotten father of the Internet: ARPANET.

 

     In far 1958, answering on Soviet satellite launch, USA create Defense Advanced Research Projects Agency (shortly - DARPA) specialising on researches in computer technologies area. For a decade, all proceeding, collecting and transfering data was performing via punched cards, what made process of researching more struggling.

    Then, approximately in 1966, American Department of Defense came up with the idea that in case of war USA need reliable system for data transfer and suggested to develop a computer network for it.

    So, after solving lots of issues, in 1969 the Advanced Research Projects Agency Network (shortly - ARPANET) was introduced.

    ARPANET is commonly known as the first wide-area packet-switching network working with TCP/IP protocol.

    Later, ARPANET becomes international due to connecting foreign organizations from UK and Norway in 1973.

    Being first prototype of the Internet, ARPANET existance was ended in June, 1990.

Teema 10 - Võrkude rikkusː vabast tarkvarast vaba kultuurini

  Review on Eric S. Raymondi Hacker-HOWTO.   The poem is nice, it describes the path you should follow to become a hacker perfectly. Learn from the best, practice, and become a professional yourself. To be recognized as a hacker and gain respect, I think it is natural to believe you should always share your precious knowledge and in turn preserve other’s knowledge. To achieve your dreams, you cannot give up. Even if you must perform the same task repeatedly, you continue. It may be boring, but it will pay off in the end. I do believe however, that as much as you can develop your own instinctive hostility towards censorship and so on, you cannot break the law. In my opinion the law should always be respected. Practice and dedication are key for success. Python is a very good choice when it comes to learning your first programming language, however, C# or C++ can be much more powerful. The article is a bit outdated from my point of view, Java may still be commonly used withi

Analytize ACM’s Code of Ethics The Association for Computing Machinery, or ACM in short, designed a well-documented guideline for ethical conduct which all computing professionals should follow. When violations occur, the code can be used upon a remediation basis. The Code serves as a basis for decision-making when it comes to ethical judgement, it specifies which multiple principles should be taken into account. The professional (enterprise) computing environment as a whole befits from the ethical decision-making process being transparent and accountable to all stakeholders. The Code of Ethics addresses four sections, this analysis will briefly describe section 1; the fundamental ethical principles. The other three sections address more specific situations as well as leadership and compliance, which means they are not relevant for the scope of this blog; which is describing the fundamental principles of ACM’s Code of Ethics. The Code describes seven principles all computing prof

Review of the "Arvutimängude areng ja mõju" group work.

  Introduction This review is written for the group work "Arvutimängude areng ja mõju", which was written in a Wiki-article format for the ITSPEA course. After reading this work, I would like to express that work left more positive emotions, but as nothing is ideal, there are some drawbacks that could be improved. Topic selection In my opinion, topic is chosen correctly, since this theme is quite relevant nowadays. With quick growth of personal computers and video games, frequent prejudices have appeared that playing this type of games makes children aggressive and injured, and so on. Topic became even more actual since the global isolation started. For staying safe, plenty of people prefer spending their free time with video games, so that there would be no need to go outside for having more familiar types of entertainment. Therefore, this group work can be useful in educating unexperienced people, letting them find out the history of video games and its influence. Work'
