Python (programming language)
–
Python is a widely used high-level programming language for general-purpose programming, created by Guido van Rossum and first released in 1991. The language provides constructs intended to enable writing clear programs on both a small and large scale and it has a large and comprehensive standard library. Python interpreters are available for operating systems, allowing Python code to run on a wide variety of systems. CPython, the implementation of Python, is open source software and has a community-based development model. CPython is managed by the non-profit Python Software Foundation, about the origin of Python, Van Rossum wrote in 1996, Over six years ago, in December 1989, I was looking for a hobby programming project that would keep me occupied during the week around Christmas. Would be closed, but I had a computer. I decided to write an interpreter for the new scripting language I had been thinking about lately, I chose Python as a working title for the project, being in a slightly irreverent mood. Python 2.0 was released on 16 October 2000 and had major new features, including a cycle-detecting garbage collector. With this release the development process was changed and became more transparent, Python 3.0, a major, backwards-incompatible release, was released on 3 December 2008 after a long period of testing. Many of its features have been backported to the backwards-compatible Python 2.6. x and 2.7. x version series. The End Of Life date for Python 2.7 was initially set at 2015, many other paradigms are supported via extensions, including design by contract and logic programming. Python uses dynamic typing and a mix of reference counting and a garbage collector for memory management. An important feature of Python is dynamic name resolution, which binds method, the design of Python offers some support for functional programming in the Lisp tradition. The language has map, reduce and filter functions, list comprehensions, dictionaries, and sets, the standard library has two modules that implement functional tools borrowed from Haskell and Standard ML. Python can also be embedded in existing applications that need a programmable interface, while offering choice in coding methodology, the Python philosophy rejects exuberant syntax, such as in Perl, in favor of a sparser, less-cluttered grammar. As Alex Martelli put it, To describe something as clever is not considered a compliment in the Python culture. Pythons philosophy rejects the Perl there is more one way to do it approach to language design in favor of there should be one—and preferably only one—obvious way to do it. Pythons developers strive to avoid premature optimization, and moreover, reject patches to non-critical parts of CPython that would offer an increase in speed at the cost of clarity

Paraguay
–
Paraguay lies on both banks of the Paraguay River, which runs through the center of the country from north to south. Due to its location in South America, it is sometimes referred to as Corazón de Sudamérica. Paraguay is one of the two landlocked countries that lie outside Afro-Eurasia, Paraguay is the smallest landlocked country in the Americas. The indigenous Guaraní had been living in Paraguay for at least a millennium before the Spanish conquered the territory in the 16th century, Spanish settlers and Jesuit missions introduced Christianity and Spanish culture to the region. Paraguay was a colony of the Spanish Empire, with few urban centers and settlers. Following independence from Spain in 1811, Paraguay was ruled by a series of dictators who generally implemented isolationist and protectionist policies and he was toppled in an internal military coup, and free multi-party elections were organized and held for the first time in 1993. A year later, Paraguay joined Argentina, Brazil and Uruguay to found Mercosur, as of 2009, Paraguays population was estimated to be at around 6.5 million, most of whom are concentrated in the southeast region of the country. The capital and largest city is Asunción, of which the area is home to nearly a third of Paraguays population. In contrast to most Latin American nations, Paraguays indigenous language and culture, Guaraní, in each census, residents predominantly identify as mestizo, reflecting years of intermarriage among the different ethnic groups. Guaraní is recognized as an official language alongside Spanish, and both languages are spoken in the country. There is no consensus for the derivation or meaning of the name Paraguay, the most common interpretations include, Born from water Riverine of many varieties River which originates a sea Fray Antonio Ruiz de Montoya said that it meant river crowned. The Spanish officer and scientist Félix de Azara suggests two derivations, the Payaguas, referring to the tribe who lived along the river. The French-Argentine historian and writer Paul Groussac argued that it meant river that flows through the sea, Paraguayan poet and ex-president Juan Natalicio González said it meant river of the inhabitants of the sea. Indigenous peoples have inhabited this area for thousands of years, pre-Columbian society in the region which is now Paraguay consisted of semi-nomadic tribes that were known for their warrior traditions. These indigenous tribes belonged to five language families, which was the basis of their major divisions. Differing language groups were generally competitive over resources and territories and they were further divided into tribes by speaking languages in branches of these families. Today 17 separate ethnolinguistic groups remain, the first Europeans in the area were Spanish explorers in 1516. The Spanish explorer Juan de Salazar de Espinosa founded the settlement of Asunción on 15 August 1537, the city eventually became the center of a Spanish colonial province of Paraguay

Internet
–
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, the primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. Although the Internet was widely used by academia since the 1980s, Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the two decades since then, Internet use has grown 100-times, measured for the period of one year, newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The entertainment industry was initially the fastest growing segment on the Internet, the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking. Business-to-business and financial services on the Internet affect supply chains across entire industries, the Internet has no centralized governance in either technological implementation or policies for access and usage, each constituent network sets its own policies. The term Internet, when used to refer to the global system of interconnected Internet Protocol networks, is a proper noun. In common use and the media, it is not capitalized. Some guides specify that the word should be capitalized when used as a noun, the Internet is also often referred to as the Net, as a short form of network. Historically, as early as 1849, the word internetted was used uncapitalized as an adjective, the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are often used interchangeably in everyday speech, however, the World Wide Web or the Web is only one of a large number of Internet services. The Web is a collection of interconnected documents and other web resources, linked by hyperlinks, the term Interweb is a portmanteau of Internet and World Wide Web typically used sarcastically to parody a technically unsavvy user. The ARPANET project led to the development of protocols for internetworking, the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of Utah Graphics Department. In an early sign of growth, fifteen sites were connected to the young ARPANET by the end of 1971. These early years were documented in the 1972 film Computer Networks, early international collaborations on the ARPANET were rare. European developers were concerned with developing the X.25 networks, in December 1974, RFC675, by Vinton Cerf, Yogen Dalal, and Carl Sunshine, used the term internet as a shorthand for internetworking and later RFCs repeated this use. Access to the ARPANET was expanded in 1981 when the National Science Foundation funded the Computer Science Network, in 1982, the Internet Protocol Suite was standardized, which permitted worldwide proliferation of interconnected networks.5 Mbit/s and 45 Mbit/s. Commercial Internet service providers emerged in the late 1980s and early 1990s, the ARPANET was decommissioned in 1990

Internet Assigned Numbers Authority
–
Following ICANNs transition to a global multistakeholder governance model, the IANA functions were transferred to Public Technical Identifiers, an affiliate of ICANN. In addition, five regional Internet registries delegate number resources to their customers, local Internet registries, Internet service providers, a local Internet registry is an organization that assigns parts of its allocation from a regional Internet registry to other customers. Most local Internet registries are also Internet service providers, IANA is broadly responsible for the allocation of globally unique names and numbers that are used in Internet protocols that are published as Request for Comments documents. These documents describe methods, behaviors, research, or innovations applicable to the working of the Internet, IANA maintains a close liaison with the Internet Engineering Task Force and RFC Editorial team in fulfilling this function. IANA is responsible for assignment of Internet numbers which are numerical identifier assigned to an Internet resource or used in the protocols of the Internet Protocol Suite. Examples include IP addresses and autonomous system numbers, IANA delegates allocations of IP address blocks to regional Internet registries. Each RIR allocates addresses for a different area of the world, collectively the RIRs have created the Number Resource Organization formed as a body to represent their collective interests and ensure that policy statements are coordinated globally. The RIRs divide their allocated address pools into smaller blocks and delegate them to Internet service providers, since the exhaustion of the Internet Protocol Version 4 address space, no further IPv4 address space is allocated by IANA. IANA administers the data in the root nameservers, which form the top of the hierarchical Domain name system tree and this task involves liaising with top-level domain operators, the root nameserver operators, and ICANNs policy making apparatus. IANA administers many parameters of IETF protocols, examples include the names of uniform resource identifier schemes and character encodings recommended for use on the Internet. This task is performed under the oversight of the Internet Architecture Board, on March 26,1972, Vint Cerf and Jon Postel at UCLA called for establishing a socket number catalog in RFC322. Network administrators were asked to submit a note or place a call, describing the function. This catalog was published as RFC433 in December 1972. In it Postel first proposed a registry of assignments of port numbers to network services, calling himself the czar of socket numbers. The first reference to the name IANA in the RFC series is in RFC1083, published in December,1988 by Postel at USC-ISI, there was widespread dissatisfaction with this concentration of power in one company, and people looked to IANA for a solution. Postel wrote up a draft on IANA and the creation of new top level domains and he was trying to institutionalize IANA. In retrospect, this would have been valuable, since he died about two years later. Jon Postel managed the IANA function from its inception on the ARPANET until his death in October 1998, by his almost 30 years of selfless service, Postel created his de facto authority to manage key parts of the Internet infrastructure

ISO 3166-1 alpha-2
–
They are the most widely used of the country codes published by ISO, and are used most prominently for the Internets country code top-level domains. They were first included as part of the ISO3166 standard in its first edition in 1974, the ISO 3166-1 alpha-2 codes are used in different environments and are also part of other standards. In some cases they are not perfectly implemented, the ISO 3166-1 alpha-2 codes are used in the following standards, Starting in 1985, ISO 3166-1 alpha-2 codes have been used in the Domain Name System as country code top-level domains. The Internet Assigned Numbers Authority currently assigns the ccTLDs mostly following the alpha-2 codes, but with a few exceptions. For example, the United Kingdom, whose code is GB, uses. uk instead of. gb as its ccTLD. The European Commission generally uses ISO 3166-1 alpha-2 codes with two exceptions, EL is used to represent Greece, and UK is used to represent the United Kingdom. This notwithstanding, the Official Journal of the European Communities specified that GR and GB be used to represent Greece, for VAT administration purposes, the European Commission uses EL and GB for Greece and the United Kingdom respectively. IETF language tags are also derived from ISO 3166-1 alpha-2 codes. The full list of ISO 3166-1 codes assigned to countries and territories are usable as region subtags, also, the exceptionally reserved alpha-2 codes defined in ISO 3166-1 are also usable as region subtags for language tags. Some other region grouping subtags are derived from other standards, under the newer stability policies, old assigned codes that have been withdrawn from ISO 3166-1 should no longer be reassigned to another country or territory. The following is a colour-coded decoding table of all ISO 3166-1 alpha-2 codes, click on the cell to see the definition of each code. The following alpha-2 codes can be user-assigned, AA, QM to QZ, XA to XZ, for example, UN/LOCODE assigns XZ to represent installations in international waters. The Unicode Common Locale Data Repository assigns QO to represent Outlying Oceania, before the adoption of the macroregion code EU by ISO, CLDR also used QU to represent the European Union. The code XK is being used by the European Commission, the IMF, the code XA is being used by Switzerland, as a country code for the Canary Islands, although IC is already reserved for that purpose. The code XN is being used by the World Intellectual Property Organization as an indicator for the Nordic Patent Institute, the codes XE, XS and XW are used by WhatsApp to represent the flags of England, Scotland and Wales as Emoji. Reserved code elements are codes which have become obsolete, or are required in order to enable a user application of the standard. The reserved alpha-2 codes can be divided into the four categories, exceptional reservations, transitional reservations, indeterminate reservations. These codes may be used only during a period of at least five years while new code elements that may have replaced them are taken into use

. au is the Internet country code top-level domain for Australia. It was first created on 5 March 1986, Domain name policy is managed by. au Domain Administration, with the registry operated by AusRegistry. The domain name was allocated by Jon Postel, operator of IANA to Kevin Robert Elz of Melbourne University in 1986. After an approximately five-year process in the 1990s, the Internet industry created a body called. au Domain Administration to operate the domain. It obtained assent from ICANN in 2001, and commenced operating a new regime for domain registration on 1 July 2002. Since this new regime, any registration has to be ordered via a registrar, oversight of. au is by. au Domain Administration. It is an organisation whose membership is derived from Internet organisations, industry members. The organisation operates with the endorsement of the Australian Government and with the authority of ICANN. Policy for. au is devised by policy development panels and these panels are convened by auDA and combine public input with industry representation to derive policy. The day-to-day operation of the. au registry technical facility is tendered out by auDA, the current operator is AusRegistry who has performed this role since the initial tender in 2002. AusRegistry does not sell domain registration services direct to the consumer, rather consumers who wish to register a domain must do so via a domain name registrar, after the industrys liberalisation in 2002, there is an active competitive market in registrars with a variety of prices and services. In 2008 auDA changed its policy and allowed changes in ownership of. au domains. AuDA introduced the ISS in October 2013 as a mandatory requirement, discount Domain Name services, Cheaper Domains and Information Brokers, part of the Total Internet Group, are the first three auDA accredited registrars to achieve ISS compliance. The naming rules for. au require registrations under second-level categories that describe a type of entity. com. au and this follows a similar allocation policy to that formerly used in other countries such as the United Kingdom and New Zealand. Registrations are currently permitted below a second-level domain, such as yourname. com. au, in April 2016, auDA announced it would introduce registrations directly at the second level, such as yourname. au. Direct registrations are due to be implemented in 2017, registering a domain in the. au namespace requires registrants to have either an exact match or a “close and substantial connection” to their desired domain name. Registration of a. au domain is completed through a reseller, known as a registrar and these domains are managed by the. au Community Domains Trust on behalf of auDA. CGDNs use the state or territorys common abbreviation as the level of the domain

. bi is the Internet country code top-level domain for Burundi. It is administered by the Burundi National Center of Information Technology, the registry site states that. BI Registry has a rather liberal policy about domain names as soon as the domain name is in relation with the business name or one of its marks. The general principle is that a domain must reflect the truth, registrations are open to anybody worldwide, but are not supposed to be registered or used for misleading purposes, though apparently no pre-screening is done to ensure this. The site also states that We strongly discourage the use of suffixes of our country for misleading people and we remind that. bi stands for Republic of Burundi and for nothing else. This is apparently intended to discourage the repurposing of. bi as has been done with other ccTLDs, or the use in domain hacks where the TLD becomes part of a word or phrase. Use of bi in the sense of bisexuality is likely the sort of thing they are aiming to prevent and it is used by the Israeli company Vision. bi, which develops Business Intelligence software. There does not seem to be much use at all, either within or outside Burundi

. br is the Internet country code top-level domain for Brazil. It was administered by the Brazilian Internet Steering Committee until 2005 when it started being administered by Brazilian Network Information Center, a local contact is required for any registration. Registrations of domain names with Portuguese characters are also accepted, with the exception of universities, the second-level domain is fixed and selected from a list that defines the category. For example, site. art. br is in the art category, institutions of tertiary education were allowed to use the ccSLD. edu. br, although some use. com. br and others use. br. There are also some few exceptions that were allowed to use the second level domain until the end of 2000. As of April 2010, most domain registrations ignore categories and register in the. com. br domain, the. jus. br, and. b. br domains have mandatory DNSSEC use. Created and delegated to Brazil in 1989 by Jon Postel, initially the domain was operated manually by Registro. br, originally, only researchers and institutions to which they belonged had the interest and ability to adopt the new system and register domains under. br. At the time, networks prevalent in the Brazilian academic setting were the BITNET, the HEPnet, as such, even before Brazil officially connected to the Internet in 1991, the. br domain was used to identify the machines participating in networks already in use by academics. The registration system was automated in 1997 and was developed using open source software, in 2017, accounts associated with DNS records of Brazilian banks were hacked. Kasperskys researchers pointed out to a vulnerability in NIC. brs website, nICs director at the time, Frederico Neves, denied that NIC. br was hacked, although NIC admitted the vulnerability. To register any domains under. br, it is necessary to enter into contact with Registro. br, Entities legally established in Brazil as a company or a physical person that has a contact within Brazil can register domains. Foreign companies that have a legally established in Brazil can also do it by following specific rules. The registration of domains with special Portuguese characters is accepted since 2005, minimum of 2 and maximum of 26 characters, not including the category. For example, in the field XXXX. COM. BR, valid characters are, the hyphen, and the following accented characters, à, á, â, ã, é, ê, í, ó, ô, õ, ú, ü, ç. To maintain the integrity of the registry, Registro. br sets up an equivalence mapping to compare domain names with, the mapping is done by converting accented characters and the cedilla for their non-accented versions and c, respectively, and discards hyphens.

. ca is the Internet country code top-level domain for Canada. The domain name registry that operates it is the Canadian Internet Registration Authority, registrants can register domains at the second level. Third-level registrations in one of the geographic third-level domains defined by the registry were discontinued on October 12,2010, registrants of. ca domains must meet the Canadian Presence Requirements as defined by the registry. The first. ca domain was registered by the University of Prince Edward Island in January 1988. ca Registry, the Canadian Internet Registration Authority is a non-profit Canadian corporation that is responsible for operating the. ca Internet country code Top Level Domain today. It assumed operation of the. ca ccTLD on December 1,2000, on April 15,2008, CIRA registered its one millionth. ca Internet domain name. Any. ca registration has to be ordered via a certified registrar, uBCs registry operations once favoured fourth-level names for purely local entities or third-level names for entities operating solely within one province. Nationally incorporated companies could have a. ca domain, while provincially incorporated companies required the letters of their province, currently, any of the above listed parties can register a domain with a name of their choosing followed directly by. ca. CIRA stopped accepting new registrations for third-level domains on October 12,2010, citing complexity, gc. ca is actually a standard domain like all other. ca domain names. CIRA does not register domain names under. gc. ca directly, the. mil. ca second-level domain name is also a standard domain and is registered to the Department of National Defence. The. mil. ca suffix is used internally by DND on its intranet, internationalized domain names were introduced in January 2013 with a limited selection of characters to allow French language text with diacritics. Names which differ only in diacritical accents must have the same owner, Domain names that begin with the four characters xn-- are otherwise not available for registration. Length must be 2-63 characters, including the xn-- prefix encoding for internationalised domain names, names which match the name of an existing generic three-letter top level domain or the Canadian top level country code are reserved and therefore not available for new registrations. Certain expletives are not accepted as names, municipal names of individual cities and localities within Canada are also reserved nationwide, along with village. ca, hamlet. ca, town. ca, city. ca, ville. ca and the names of Canadian provinces. Exceptions were typically names registered before the restriction was introduced, such as the Canadian Governor General at gg. ca, names which exist at any of the levels are blocked in their availability elsewhere in the. ca hierarchy. Registration, if it can be done at all, requires manual intervention by the prospective registrar as the permission of all existing registrant must be obtained by CIRA. Registering this domain name requires permission from the Registrant that already holds the name, gouv. on. ca, gouv. pe. ca. However, with the agreement of these three parties New Brunswick would indeed be able to register and use gouv. nb. ca, existing third-level domain registrants looking to obtain the corresponding second-level domain are normally advised to use the same initial registrar for both names. After a thirty-day redemption period, intended to provide the original registrant one final chance to reclaim a suspended name, domains which receive no bids are then released and made openly available for new registrations
