OPENSOURCE.COM FROM THE EDITOR ...... ........ .. .. .. ... .... Dear Open Source Yearbook reader, In 2015, Opensource.com published the first Open Source Yearbook[1] , and thanks to contributions from more than 25 writers, the 2016 edition [2] was even bigger and included more than 100 organizations, projects, technologies, and events. In the 2017 edition, we offer a pleasing mix of new tech trends and nostalgia. We celebrate 60 years of Fortran and 30 years of Perl, and we learn how to run old DOS programs under Linux. We also dive into the world of machine learning and AI, the increasingly popular Go programming language and the rapidly growing adoption of Kubernetes, and the ongoing challenge of teaching operations to software developers. Thank you to everyone who contributed to the 2017 Open Source Yearbook [3], and to the communities who helped create, document, evangelize, and share open source open source technologies and methodologies throughout the year. And a special thanks to the following writers for their contributions: • David Both • Mike Bursell • Ben Cotton • Jeremy Garcia • Gordon Haff • Jim Hall • Scott Hirleman • Ruth Holloway • Elizabeth K.

  • Domain Name System 1 Domain Name System
    Domain Name System 1 Domain Name System The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. A Domain Name Service translates queries for domain names (which are easier to understand and utilize when accessing the internet) into IP addresses for the purpose of locating computer services and devices worldwide. An often-used analogy to explain the Domain Name System is that it serves as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses. For example, the domain name www.example.com translates to the addresses 192.0.43.10 (IPv4) and 2620:0:2d0:200::10 (IPv6). The Domain Name System makes it possible to assign domain names to groups of Internet resources and users in a meaningful way, independent of each entity's physical location. Because of this, World Wide Web (WWW) hyperlinks and Internet contact information can remain consistent and constant even if the current Internet routing arrangements change or the participant uses a mobile device. Internet domain names are easier to remember than IP addresses such as 208.77.188.166 (IPv4) or 2001:db8:1f70::999:de8:7648:6e8 (IPv6). Users take advantage of this when they recite meaningful Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer actually locates them. The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain.
