I'm just a Software Sojourner (hence my nom de network, which is an abbreviation of Software Hobbit).

More formally, I am Drew Derbyshire, a professional software developer.

On the side, I am the proprietor of Kendra Electronic Wonderworks, a small software house founded in 1989. It mostly does OSS. After almost 18 years in Massachusetts, we moved to Kenmore, Washington (north of Seattle) in 2007.

I started in operations, but I have been mostly in development since my misspent youth.

I've made money in (chronological order, not level of expertise!) using COBOL, PL/I, IBM Assembler, ROSCOE RPF, EXEC2, REXX, C/C++, Java, Bourne Shell, Python, Perl, JS, and FORTRAN IV. (Not that I often admit the last two. I also only admit that I know Go under duress, because I've never used it professionally.)

When I next look for work, it will likely be in C/C++, Java, Python, or perhaps Go.

I have used more OS families than most people have, including:

• Many generations of IBM OS/360 and its successors
• Many generations of IBM VM/370 and its successors
• IBM DOS/VSE
• MUSIC (McGill University System for Interactive Computing)
• Singer System Ten
• Digital Equipment Corporation TOPS-10
• Digital Equipment Corporation VMS
• TRS-80 Level I BASIC
• CP/M
• MS-DOS from 1.x to the current FreeDOS
• Windows from 3.0 to present day
• OS/2 from 1.2 to 4.52
• MacOS X and its successors
• Many, many flavors of UNIX:
  • Amdahl UTS
  • SCO UNIX / Unixware
  • AIX
  • SunOS / Solaris
  • BSD / FreeBSD / NetBSD
  • Linux (including RedHat, Ubuntu, Raspberry Pi OS, and others)

I beat the rush to multiprocessor systems in the late 1980s, and I did massively parallel systems in early 1990s.

I detoured into SRE under the guy who originated it. I've carried a pager enough there and elsewhere that my phone is grafted to me.

I did OSS (e-mail via dial-up UUCP) before the term existed. (It was also before dial-up UUCP convincingly lost the protocol war to SMTP/POP3/IMAP4 over always on connections.) Its website is still at UUPC.net, and the source is also here on Github at github.com/swhobbit/UUPC.

My oldest Internet domain is probably older than yours.

I am the volunteer valet to an IBM 4361 running VM/SP 5, which can be remotely accessed for free. (Disclaimer: I neither work for nor speak for its owners.)
