The first “Berkeley So]ware Distribu$on” (BSD) is released. • 1989 – UNIX System V, the last tradi$onal UNIX version. • 1991 – Linus Torvalds begin developing Linux. “UNIX-like” • Today – UNIX itself, what’s now called “tradi$onal UNIX” is not used, except by enthusiasts. • There are many “UNIX-like” systems (also known as *nix or UN*X) that are similar to UNIX while not conforming to the Single UNIX Specificaon. • In fact, most operang systems today except windows are “UNIX like”. Single UNIX Specificaon (SUS) • Developed and maintained by the Aus$n Group, based on earlier work by the IEee and The Open Group. • In 1988, these standards became IEee 1003 (also registered as ISO/IEC 9945), or POSIX, which loosely stands for “Portable Operang System Interface for uniX” • Last major revision 2008, POSIX:2008 (formally: IEee Std 1003.1-2008) UNIX-like History 1969 Unics 1969 Open Source 1971 to 1973 UnixTSS 1 to 4 Mixed/Shared Source 1971 to 1973 1974 to 1975 UnixTSS PWB/Unix 5 to 6 Closed Source 1974 to 1975 1978 BSD 1978 1.0 to 2.0 UnixTSS 1979 7 1979 Unix 32v 1980 BSD 1980 3.0 to 4.1 1981 Xenix System III 1.0 to 2.3 1981 1982 Xenix 1982 3.0 1983 BSD 4.2 Sun OS System V 1983 1 to 1.1 R1 to R2 1984 SCO Xenix 1984 UnixTSS 1985 8 SCO Xenix 1985 AIX W286 System V 1986 BSD 4.3 1.0 R3 HP/UX Sun OS 1.0 to 1.2 1986 1.2 to 3.0 SCO Xenix 1987 UnixTSS V386 1987 (Time Sharing HP/UX 1988 System) BSD 4.3 System V R4 2.0 to 3.0 1988 9 to 10 Tahoe SCO Xenix 1989 W386 1989 BSD 4.3 1990 Reno 1990 BSD NET/2 1991 Linux 0.0.1 1991 Sun OS Minix 4 1.x NEXTSTEP/ 386BSD OPENSTEP 1992 1992 1.0 to 4.0 HP/UX NetBSD 6 to 11 Linux BSD 0.8 to 1.0 1993 1993 0.95 to 1.2.x SCO Unix 4.4 to 3.2.4 Unixware FreeBSD 4.4 lite2 1.x to 2.x 1994 1994 1.0 to 1995 2.2.x NetBSD OpenBSD 1995 1.1 to 1.2 OpenServer 1.0 to 2.2 5.0 to 5.04 Solaris 1996 AIX 2.1 to 10 1996 3.x to 7.1 1997 1997 NetBSD 1.3 1998 FreeBSD 1998 3.0 to 3.2 Minix OpenServer Unixware 1999 2.x Mac OS X 5.0.5 to 5.0.7 7.x Linux Server 2000 1999 2.0 to 2.6.x OpenBSD 2.3 to 5.0 2000 2001 to 2004 FreeBSD NetBSD 2001 to 2004 3.3 to 8.2 1.3 to 5.x HP/UX 2005 Mac OS X 11i to 11i v3 2005 10.0 to 10.7.x (Darwin) OpenServer OpenSolaris 2006 to 2010 Minix 6.0 2008.05 to 2006 to 2010 3.x 2009. 2011 Linux 3.x 2011 Open Source • GNU GPL, versions 2 and 3 is very common.

  • The Intel Management Engine: an Attack on Computer Users' Freedom by Denis Gnutoo Carikli
    A statement by FSF President Richard Stallman on the Intel Management Engine (ME): "Meltdown and Spectre are errors. Grave errors, to be sure, but not evidently malicious. Everyone makes mistakes. Intel has done far worse with its CPUs than make a mistake. It has built in an intentional back door called the Management Engine. Important as these bugs are, don©t let Intel©s mistakes distract you from Intel©s deliberate attack!" The Intel Management Engine: an attack on computer users© freedom By Denis GNUtoo Carikli With security issues like the Spectre and Meltdown vulnerabilities (https://www.cnet.com/news/meltdown-spectre-intel-ceo-no-recall-chip-processor/) discovered in Intel chips in early 2018, it became more important than ever to talk about the necessity of software freedom in these deeply embedded technologies. Serious as though these bugs may be, we cannot let them distract us from the broader issues: Intel considers the Intel Management Engine a feature, while it©s nothing more than a threat to user freedom. Thanks to Denis GNUtoo Carikli, we have a new basis for that conversation in this article. The Intel Management Engine is a tool that ships with Intel chipsets, purportedly to ease the job of system administrators. But in reality, it is another restriction on user freedoms, imposed by a company, and used to control your computing. Carikli offers a moderately technical explanation of what©s happening with Management Engine, the ways in which it restricts rather than empowers users, and how it violates the four freedoms of free software. Carikli may be best known for his work on the Replicant project (https://www.replicant.us/), which he co-founded with Aaron Williamson, Bradley Kuhn, and Grazlano Sorbaioli.

  • Chapter 4 Introduction to UNIX Systems Programming
    Chapter 4 Introduction to UNIX Systems Programming 4.1 Introduction Last chapter covered how to use UNIX from from a shell program using UNIX commands. These commands are programs that are written in C that interact with the UNIX environment using functions called Systems Calls. This chapter covers this Systems Calls and how to use them inside a program. 4.2 What is an Operating System An Operating System is a program that sits between the hardware and the application programs. Like any other program it has a main() function and it is built like any other program with a compiler and a linker. However it is built with some special parameters so the starting address is the boot address where the CPU will jump to start the operating system when the system boots. Draft An operating system typically offers the following functionality: ● Multitasking The Operating System will allow multiple programs to run simultaneously in the same computer. The Operating System will schedule the programs in the multiple processors of the computer even when the number of running programs exceeds the number of processors or cores. ● Multiuser The Operating System will allow multiple users to use simultaneously in the same computer. ● File system © 2014 Gustavo Rodriguez-Rivera and Justin Ennen,Introduction to Systems Programming: a Hands-on Approach (V2014-10-27) (systemsprogrammingbook.com) It allows to store files in disk or other media. ● Networking It gives access to the local network and internet ● Window System It provides a Graphical User Interface ● Standard Programs It also includes programs such as file utilities, task manager, editors, compilers, web browser, etc.
