Task: Question Answering
Input (English): Context_1 : Sense is an educational programming environment created by The Open University (OU) in the United Kingdom. It uses a drag-and-drop programming environment designed to teach students the fundamentals of computer programming, using different shape and colour "blocks" selected from a palette of available commands, meaning that the student needs no prior experience of programming nor need to learn a syntax. It is based on the Scratch programming language developed by the MIT Media Lab, and uses .sb files like Scratch but the two pieces of software cannot use each other's files. Context_2 : hoc, an acronym for High Order Calculator, is an interpreted programming language that was used in the 1984 book The Unix Programming Environment to demonstrate how to build interpreters using Yacc. Context_3 : Lava is an experimental, visual object-oriented, interpreter-based programming language with an associated programming environment (Lava Programming Environment or LavaPE) that uses structure editors instead of text editors. Only comments, constants, and new identifiers may be entered as text. Context_4 : Advanced Programming in the Unix Environment is a computer programming book by W. Richard Stevens describing the application programming interface of the UNIX family of operating systems. The book illustrates UNIX application programming in the C programming language. Context_5 : Spring is a discontinued project/experimental microkernel-based object oriented operating system developed at Sun Microsystems in the early 1990s. Using technology substantially similar to concepts developed in the Mach kernel, Spring concentrated on providing a richer programming environment supporting multiple inheritance and other features. Spring was also more cleanly separated from the operating systems it would host, divorcing it from its Unix roots and even allowing several OSes to be run at the same time. Development faded out in the mid-1990s, but several ideas and some code from the project was later re-used in the Java programming language libraries and the Solaris operating system. Context_6 : Scott Seebass began his career in the computer networking industry at the age of 20 when he co-authored the "Unix System Administration Handbook" with Evi Nemeth, Trent R. Hein and Garth Snyder in 1989, now in its third edition. This book is a primary tutorial for Unix as it covers FreeBSD, HP-UX, Linux, and Solaris. Mr. Seebass went on to work at Interactive Systems and MT Xinu, where he focused on developing MORE/bsd, a commercial version of Unix. Recognizing the possibilities of Unix programming, Seebass co-founded Xinet in 1991, a digital asset management company. Xinet was acquired by North Plains Systems in April 2012. Seebass holds degrees in Computer Science and Statistics from University of California, Berkeley. Context_7 : The Unix Programming Environment, first published in 1984 by Prentice Hall, is a book written by Brian W. Kernighan and Rob Pike, both of Bell Labs and considered an important and early document of the Unix operating system. Context_8 : LiteOS is a real-time operating system (RTOS) from University of Illinois for use in sensor networks. LiteOS is a Unix-like operating system that fits on memory-constrained sensor nodes. This operating system allows users to operate wireless sensor networks like operating Unix, which is easier for people with adequate Unix background. LiteOS provides a familiar programming environment based on Unix, threads, and C. It follows a hybrid programming model that allows both event-driven and thread-driven programming. LiteOS is open source, written in C and runs on the Atmel AVR based MicaZ and IRIS sensor networking platform. Context_9 : Prentice Hall is a major educational publisher owned by Pearson PLC. Prentice Hall publishes print and digital content for the 6–12 and higher-education market. Prentice Hall distributes its technical titles through the Safari Books Online e-reference service. Context_10 : The Art of Unix Programming by Eric S. Raymond is a book about the history and culture of Unix programming from its earliest days in 1969 to 2003 when it was published, covering both genetic derivations such as BSD and conceptual ones such as Linux. fact_1 : The Unix Programming Environment, first published in 1984 by Prentice Hall, is a book written by Brian W. Kernighan and Rob Pike, both of Bell Labs and considered an important and early document of the Unix operating system. fact_2 : Prentice Hall is a major educational publisher owned by Pearson PLC. Question: The Unix Programming Environment was published by a company that is owned by who?
Output (English): Pearson PLC
