    “BSD/OS supports the IEEE POSIX 1003.1 standard. BSDi has tracked the IEEE POSIX 1003.2 standard and is modifying utilities to conform. BSD/OS networking includes both the OSI and TCP/IP standards. The BSD/OS C compiler (gcc) supports ANSI C; all system headers comply with ANSI-C’s requirements. The X Window System (Version X11R6) is an industry standard window system based on software from MIT.”w40

    “Yesterday’s college students learned their UNIX expertise on Linux and FreeBSD. Today they’re working in IT departments, and many of them are openly hostile to both Microsoft and Windows NT. As a result, Linux, BSD, Solaris, and other forms of UNIX are finding their way into IT departments, both overtly and on the sly.

    “For example, are you sure that’s an NT server you’re connecting to at work? IS employees in many corporations have secretly installed UNIX servers that provide native NT services. Why take such a risk? Linux and FreeBSD are free, as is SAMBA, the software that provides NT services. So the IS department saves money. And managers are unlikely to find out UNIX is behind the scenes because fewer people will complain about server downtime.

    “Fewer people will complain because the servers are more stable than Windows NT. Linux, FreeBSD, and BSDI UNIX outperform Windows NT by a wide margin on limited hardware, and under some circumstances can perform as well or better than NT on the best hardware. Once behind in scalability features, UNIX on Intel is catching up and may soon surpass NT in the number of processors it can use, and how it uses them.” —Nicholas Petreley (editor-in-chief of NC World and columnist for InfoWorld and NT World Japan), “The new UNIX alters NT’s orbit: The re-emergence of UNIX threatens to modify the future direction of NT”, NC World, April 1998w51

Application Programs:



    “Why does Wind River need both BSD/OS and FreeBSD? Wind River’s customers demand a fully supported commercial system with carefully controlled product direction, quality, and support. BSD/OS provides these benefits and Wind River will therefore continue to invest in the direct development of BSD/OS and its successors. These will provide the primary revenue engine for the BSD technology.

    “Wind River also recognizes the enormous leverage that open source projects can provide. When encouraged to prosper, open source can produce a wide variety of useful, stable technology and ideas. FreeBSD offers this opportunity for Wind River to cultivate. BSD/OS and other Wind River products will selectively incorporate technology or ideas surfaced by FreeBSD, including applications and drivers, and BSD/OS will maintain a high degree of compatibility with FreeBSD to optimize this synergy. To encourage the growth of FreeBSD, Wind River will also selectively donate technologies to the open source community. This plan provides Wind River customers with the best of both open source and commercial systems.” —Wind River, “bsdi_faq”, May 2001w71

    “How do FreeBSD and BSD/OS fit into Wind River’s product strategy? As embedded applications become more and more connected, it is imperative that they have the ability to interoperate with the mission-critical applications running on the Internet.

    “The agreement to acquire BSDi software gives Wind River customers the assurance that their connected smart devices will be highly compatible with UNIX applications, which are the most widely deployed applications powering the Internet today.

    “The addition of a UNIX-based OS is consistent with Wind River’s strategy to be uniquely positioned to provide end-to-end solutions that enable customers to develop connected smart devices with market efficiencies in a challenging and ever-expanding market (see diagram below).” —Wind River, “bsdi_faq”, May 2001w71
