We had earlier featured many open source software, but here is a list that is the God of all the open source software, the software that is matured, well-established, popularized open source development and the use of free open source products. These projects are serving as a foundation to many software development projects, business networks and the public Internet for years and showed the world the power of community development.
1. Linux Kernel
Though Linux was not the first open source software project, it was the one that proved the world how powerful community development on an Internet scale could be. Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It is a product of thousands of project contributors all over the world. The stable, reliable, and malleable Linux kernel is the foundation of an enormous variety of operating system distributions.
2. GNU Utilities and Compilers
Every developer on Linux would have definitely come across the mighty collection of GNU utilities. The GNU Project is a flag ship of the free software movement. The GNU tools and utilities when combined with the Linux kernel, provides a complete operating system. Linux kernel, the GNU utilities and the GNU Compiler Collection make up the holy trinity of the Linux world.
The edge Windows had on Linux initially was the easy of use. However, Ubuntu over took with its principle of ease-of-use, making it the Linux distribution of choice for novice users and for sellers of PCs with Linux pre-installed. Derived from Debian GNU/Linux, it is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need – a web browser, presentation, document and spreadsheet software, instant messaging and much more.
4. FreeBSD, NetBSD and OpenBSD
FreeBSD is famous for superior reliability and performance. NetBSD is famous for supporting a wide range of hardware platforms, including embedded systems and mobile devices. OpenBSD is advertised as possibly the most secure Unix-like operating system, with a security audit that never stops.
There is Linux/Unix and there are Windows. In-between there is the Sama. Samba bridges the gaps between Linux/Unix and Windows. It allows Linux and Unix servers to provide file and print services to Windows clients, and it allows Linux and Unix clients to work with Windows file servers.
There is a huge active MySQL user community attest that has adopted MsSQL because of its easy of administration, excellent read performance, and transparent support for large text and binary objects. It had become the number one choice for many Web sites.
BIND (Berkeley Internet Name Domain) is the most popular DNS (Domain Name System) server since the dawn of the Internet. BIND is by far the most widely used DNS software on the Internet. It provides a robust and stable platform on top of which organizations can build distributed computing systems with the knowledge that those systems are fully compliant with published DNS standards.
Sendmail was born before the Internet was standardized. It served as the backbone of the Internet mail system throughout the 1980s and 1990s. It has lost ground to Postfix, Qmail, Exim, and Microsoft Exchange in recent years, but still it is among the most popular mail transfer agents.
9. OpenSSH and OpenSSL
Secure internet communication would not have been easy with tools such as rlogin and telnet, which send usernames and passwords in clear text. OpenSSH encrypts shell communications to remote computers, addressing the deficiency in tools such as rlogin and telnet. OpenSSL is a software library that allows developers to incorporate SSL or TLS into their Internet applications.
Half of the world’s Web sites run on Apache that puts the “A” in the LAMP. It its still fast, flexible and secure with broader operating system and web programming language support and many of modules available to extend the functionality. The application is available for a wide variety of operating systems, including Unix, GNU, FreeBSD, Linux, Solaris, Novell NetWare, Mac OS X, Microsoft Windows, OS/2, TPF, and eComStation
These are the best of open source software in the InfoWorld Bossies Hall Of Fame.
