SEASnet and other local resources

• You can do some of your labs on the UCLA SEASnet Computing Facility's Linux servers for CS classes. Use one of the hosts lnxsrv11, lnxsrv12, lnxsrv13, or lnxsrv15, with /usr/local/cs/bin prepended to your PATH. You can do this by executing the shell command "export PATH=/usr/local/cs/bin:$PATH" after logging in, or more conveniently by putting that shell command into your $HOME/.profile file (but test this file by logging in via a separate session before logging out of your first session!).
• You can also develop your labs on your own system, although unless otherwise specified we will test on the SEASnet servers so it’s good to test on SEASnet before submitting. If installing and/or repartitioning your system for GNU/Linux is too daunting you can try one of the following instead:
  • VirtualBox will let you run many x86-64 operating systems as a guest hosted by GNU/Linux, macOS, or MS-Windows.
  • Set up Linux on your Chromebook
  • Install Linux on Windows with WSL
  • macOS runs shell scripts natively.
• UPE Tutoring has regular office hours to help with this course, along with occasional review sessions.

POSIX

• The Open Group Base Specifications Issue 7, 2018 edition (IEEE Std 1003.1-2017) specifies the Portable Operating System Interface (POSIX) in considerable detail.
• The Austin Common Standards Revision Group develops POSIX.

GNU/Linux

• The Linux Documentation Project
• Debian – The Universal operating system

Etc.

• Operating system from Wikipedia. Wikipedia is unreliable; what problems do you detect in the lead paragraphs?
• ACM Special Interest Group in Operating Systems
• OS classes invariably talk about successes, but one can also learn about failures. For example, see: Reimer J. Half an operating system: the triumph and tragedy of OS/2 Ars Technica 2013-11-25.
