Simulation

A simulator from scratch in Common Lisp for some of IBM’s AJS job scheduler that I actually used for validating schedules on production machines. (Github, 2013)

A little eBay auction simulator, auctions.py that was a first stab at using simpy.

Mathy stuff

Playing with The Möbius Function in bash — A little visualization of the Möbius function and related things, using Bash and Awk, mainly. (Local, 2018.4)

A K-nearest neighbor classifier in Bash — A ridiculous thing, but fun. (Local, 2019.7)

Documentation and How-to

Awesome Line Editors — Information about old-fashioned “line editors” like the Unix ed(1) editor. A work in progress, and a bit tongue-in-cheek, but it actually represents a fair good bit of research. (Github, 2024).

Tally Systems for Hand Collection of Data — Wherein is suggested a novel (I assume) method of making hand tally marks for collection of count data. (LinkedIn, 2018.03.23)

Using Split-Screen mode in Android Nougat for Quicker Data Entry — A quick how-to. (LinkedIn, 2018.03.03)

seu-refcard — A cheatsheet (not written by me) re-coded in Emacsorg-mode format and converted to PDF for IBM’s SEU editor used on the IBM i (neé AS/400 or iSeries). (Github, 2014)

Helping Papa Gump Find a Name for his Son With Common Lisp — A rather irreverent example of using the Common Lisp permutations function from the Alexandria library (Blogspot, orig. 2013)

Opinion

Why Your Systems People Need a Sandbox — System administrators learn by doing. Give them a place to do it. Opinion piece. (LinkedIn, 2016.06.14)

One Space or Two — In which is answered that age-old and ever-so crucial question: One or two spaces between sentences? (Blotspot, orig. 2013)

Tools

Piltdown - Python Unicode-based data visualization library for Twitter posts. (Github, 2021)

Kallychore — Plain-text code notebook processor for mixing text and bash code, a little like Rmarkdown mixes Markdown and R. Bash with embedded awk. (Github, 2018)

whatverPython program to get the version number for any program… if you’ve told it how in advance. Well, no free lunch and all that. (Github, 2018)

Demanding Satisfaction in Emacs Lisp — A function for .emacs files to require a library, but if that doesn’t work, to automatically try to download and install it from the package archives. (2018.4)

Todostack.el — A to-do list as a stack, written in Emacs Lisp. (Github, 2011). Some description on Blogspot.

Propforth Pomodoro — A pomodoro timer using nothing but the lights on the Parallax Propeller P8X32A QuickStart microcontroller, written in 29 lines of the Propeller’s Forth dialect. (2014)

Load a Directory of Emacs Lisp Files — Rather out of date now, but included for the sake of inclusiveness. (Blogspot, Orig. Date ca. 2011)

School work and misc. exercises

Exploring the BRFSS Data — Final project from a Coursera basic stats course on exploratory data analysis in which is determined that 1) having kids makes you lose sleep, 2) Mondays don’t really suck, and 3) Colorado really is the healthiest state. Well, more or less. Rmarkdown (Local, 2016)

Math and Coding Exercises — Lots of little exercises in APL, Python, Fortran, C, Haskell, Forth, and Lisp from Project Euler, Rosetta Code, Project Lovelace, various books, etc.
