It has three editions: Ubuntu Desktop, Ubuntu Server and Ubuntu Core. It is the most popular operating system for the cloud and is used as the preferred operating system for Open Stack. It comes with a lot of applications, with more than a thousand applications available in the Ubuntu software center, and its operating system is highly customizable and has top security features. CentOS is also known as the Community Enterprise Operating System. CentOS is mainly used by businesses and developers who do not need to frequently update and install the application, which makes it more stable and secure. It's open source.

Hacker Ethic In The Modern World (Week 12)

Image
  A short opinion   The hacker ethic has to do with the idea that people do their duty for the greater good. As a result, the hacker community takes pride in the fact that they are rebelling against the authorities that restrict this level of computer freedom. Hackers are only judged by their ability, as opposed to the various systems in place that power currently dictates, such as schools and universities. Basically, the hacker ethic idealizes the notion of hacking as an art form, something revered rather than contested and frowned upon. Photo 1: Hackers [2] In today's world, hackers have about the same hacker ethic that they try to follow. According to her, the goal in itself is the search for information. Hackers take pleasure in the process of searching for knowledge, sometimes leading to hacking into computer systems. But as mentioned above, without selfish motives. The information obtained as a result is used as a positive experience and necessary knowledge. Free access ...

Two interesting cases about online censorship and about privacy (Week 11)

Image
  Internet was turned off Internet censorship is the restriction or restriction of access to some (or all) websites, imposed on certain users. This can happen due to state, ideological, economic, geographical, labor problems. Photo 1: Internet block [2] For example, desperately clinging to power, Egyptian President Hosni Mubarak turned off the Internet in the country in January 2011, thus depriving Internet journalists of the opportunity to report news to the world, and Egyptian users of access to Internet news resources. The Mubarak government, which was losing ground, could not maintain its ban for long; Internet access was restored about a week later. But the tactic of slowing down or blocking Internet access was adopted from Egypt by the governments of Libya and Bahrain, who also faced popular uprisings. [1] In the age of the Internet, governments have found many ways to control the flow of information - or at least try to do so - by interfering with or restricting digital comm...

Security situation in your home country (Week 10)

Image
Cyber security situation in Estonia  In the world of the Internet, national borders do not play a protective role: cybercriminals cannot be prevented from “entering the country”, and there is little help from the laws of the destination country if the criminal has not left his home. Cybersecurity has become an integral part of the state's internal and external security. The RIA Incident Handling Department operates in Estonia in the responsibilities of CERT at the national level and detects, monitors and resolves cybersecurity incidents in Estonian computer networks, informs about risks and organizes preventive actions. [1] Photo 1: CERT-EE [1] Technology: CERT-EE provides the following security technologies and services: The tool allows you to send suspicious files to CERT-EE for analysis: https://paste.cert.ee/ Sandbox CERT-EE (Allows you to control in a secure environment how operating systems running on various virtual and physical platforms will behave whe...

IT, Risks and Ergonomics (Week 9)

Image
Examples of ergonomics  + Always On Display Modern smartphones with an AMOLED screen matrix support an interesting and useful feature called Always on Display (AoD), which not only saves battery power, but also displays important information on the display. The AoD function in smartphones allows you to see the current time and date, assess the battery level, find out about missed incoming calls and unread messages. In this case, you do not even need to unlock access to your mobile phone. Displayed information is usually monochrome (B/W) so it is easy to see even in bright sunlight without wasting battery power. [1] On average, the always-on display consumes approximately 1% of battery power per hour. Often this figure is even lower, because when the smartphone is in your pocket or bag, the screen still turns off. With the active use of a mobile phone, energy is also not consumed to support AoD. [2] Photo 1: Always On Display [1] How to enable Always On Display on any Android smartp...

One of the Ten Commandments by Virginia Shea (Week 7)

Image
Adhere to the same standards of behavior online that you follow in real life Nowadays, more and more people communicate via the Internet and we cannot imagine our routine life without gadgets and social networking sites. Today, I want to discuss about second rule in net etiquette by Virginia Shea. Photo 1: 10 rules of netiquette  In real life, most of us obey the law, sometimes because of restrictions, sometimes because of fear of being caught. In the virtual space, the chances of being caught are relatively small. People sometimes forget that there is a living person "behind the screen", and they think that the rules of behavior on the Web are not as strict as in ordinary life. You should refrain from insults, provocations, threats and slander, respect the opinions of other participants in the dialogue, express only constructive criticism. Remember that insults in the Internet can be prosecuted. [1] In addition to, I want to give some advice: Use the correct language. Be pre...

Impact of the copyleft on choosing a software license for one's project (Week 6)

Image
Photo 1: Copyleft logo [1] The easiest way to make a program free is to declare it public property, revoking your copyright. This will allow others to share the program and its enhancements if they so desire. The impact of this is incommensurable and provides many benefits. For example, Project development within a community for improved efficiency Software program updates taken care of by others Technological bugs and advancements discovered by active users Removal of legal boundaries for more creative discoveries Customizable software tailored for specific user needs Strong copyleft The most well known free software license that uses strong copyleft is the GNU General Public License. Strong license is also Design Science License that can apply to art, music, sports photography and video. [2] Weak copyleft Weak copyleft licenses are mostly used for software libraries by allowing links to other libraries (GNU Lesser General Public License). Most important users of weak copyright are Mo...

A Review Of The Copyright reform (Week 5)

Image
Review The principal purpose of this review is to discuss changes in Copyright Reform. The authors claim that want  to  keep  copyright  for  commercial  aims, but they want to set all non-commercial copying and use it for free. To be honest, I agree with this document that copyright law should be revised because today’s ban on  non-commercial  sharing  of  culture  between  private  citizens  are threatening  fundamental  rights,  such  as  the  right  to  private  communication,  freedom of information,  and  even  the  right  to  due  process. Authors suggest some good and perspective proposals to have a freedom of information: Photo 1: DRM free [1] Moral Rights Unchanged Free Non-Commercial Sharing 20 Years Of Commercial Monopoly Registration After 5 Years Free Sampling A Ban on Digital Rights Management To sum...

Review The main purposes of this article are to discuss about the problems that the information society is facing in recent times, and highlights issues that need to be taken into account by society and government for their future beneficial development The term "information society" as "a creative society based on interaction". The author emphasizes that technological developments may not always be at the forefront of the information society, but it is important to focus on thinking about new ways of doing things. In the article, the author mentions 10 global trends (such as increasing international tax competition, regional concentration, a deepening global divide). Himanen argues that the new global division of labor and international tax competition means that the prosperous countries of Europe and America can no longer compete with the world leaders in production, since they cannot produce goods at a low price, which is now becoming a reality in 2022 and almost...

The (Not So) New Media: Facebook (Week 3)

Image
 Facebook - how it has influenced on Web Photo 1: Facebook founder - Mark Zuckerberg [1] Facebook is perhaps the most powerful social network in the world, which in a few years has turned from a service for a small circle of friends into a global platform for communication. This word is now on the lips of every representative of the progressive young generation. Gradually, Facebook becomes an integral attribute of our lives. And not by chance. Brief history of facebook Facebook as a social networking site was founded on February 4, 2004. The founder of the service is Mark Zuckerberg, who installed the portal in the university dormitory. Up until September 2005, only students used the site. In June 2006, Facebook was opened to professional communities, and in September free registration was opened on the site. [3] Why Facebook is so popular? Photo 2: Facebook popularity [3]  As a rule, any development simply does not make sense without active investment. In the process of creat...

An obsolete one technology and another which survives to this day (Week 2)

Image
 An obsolete one technology and another which survives to this day Incandescent light bulb Photo 1: Incandescent light bulb [1] Incandescent lamps are an artificial light source in which light is emitted by an incandescent body located in the bulb. Warming up due to electrical resistance, it emits light and heat, which leads to a rather irrational energy consumption. In this regard, lamps of this type were replaced by more efficient and economical lamps such as fluorescent lamps, cold cathode lamps, high-intensity discharge lamp, LEDs. [1] Incandescent light bulb consists of a base and a glass flask. Inside it is a thin tungsten spiral. She is an electrical conductor. With the passage of electricity, the spiral heats up, which is accompanied by an intense release of light. The design uses a tungsten spiral, since this material has a high temperature resistance. Any other metal would simply burn out from the heat. [2] However, an incandescent lamp is a measuring standard. Often on t...

 Three Interesting examples of IT Solutions from Three Different Decades 1. IBM PC (1980s)  Today we can’t do without a personal computer (PC) for a day, but have you ever thought about the first mass computer for a user? The IBM PC 5150 is the first mass-produced personal computer manufactured by IBM, released in 1981. The IBM 5150 includes an Intel 8088 processor. The RAM could be up to 256 kilobytes. At the same time, the cheapest version of the computer had a memory capacity of only 16 kb, expandable up to 64 kb. [1]  The IBM PC could use either a monochrome MDA video adapter (text 80x25, character size 9x14), or a color CGA video adapter (text 80x25 or 40x25, character size 8x8, or graphics 320x200/4 colors or 640×200/2 colors). Moreover, it was even possible to insert both adapters and connect two monitors at once, monochrome and color. [2]                       Photo 1: IBM 5150 [1] Factors that have contr...
