Welcome to the Leanpub Launch video for Three Essays on NetBSD https://leanpub.com/3papersnetbsd by Chris Pinnock! 0:00 Chris Pinnock introduces himself, his background in mathematics and crypto, and his early interest in NetBSD 0:47 Overview of the book's three essays and the origins of the material dating back to 1999 1:38 Essay one: why NetBSD needed to migrate from the a.out binary format to ELF, and the role of C++ requirements 2:25 Essay one walkthrough: firing up a NetBSD 1.4.3 VM and performing the a.out-to-ELF conversion hands-on 3:12 Essay two: installing NetBSD 1.0 on a virtual machine and hitting the 2 GB integer overflow boundary bug 4:06 Essay two: progressively upgrading NetBSD from 1.0 to 9.3 from source code, building the toolchain at each step 4:53 Binary compatibility result: the original NetBSD 1.0 shell still runs on NetBSD 9.3 5:40 Chris shows his freshly printed copies of his PhD thesis, master's thesis, and the NetBSD essays using Leanpub's print-ready PDF feature 6:29 Workflow: converting LaTeX to Markua, using Claude to check mathematics and catch a 30-year-old typo in his master's thesis 7:16 From print-ready PDFs to Amazon in two weeks, including an AI-generated cover, and the essays being free in ePub on Leanpub About the Book This book collects three essays I wrote in 2022 about the NetBSD operating system. In the first, we examine the transition between the a.out and ELF binary formats. We upgrade a system from one to the other. In the second essay, we install a NetBSD 1.0 system on a virtual machine, then progressively upgrade it to version 9.3. We do this from the source code, using the compiler. In the third essay, we perform an experiment and convert a NetBSD system to OpenBSD. About the Author Chris Pinnock is an IT professional living in Essex in the UK.
