Father of one, grandfather of two, pleased with all of them. I live with my Dad, who's 98 and WAY better at this than I am, for many values of "this."
Rapidly aging computer nerd.
Wannabe: knitter, geometer.
Minnesotan. Yes, it IS cold, and I like it that way.

Belated #PiDay post: occasionally I'll have a long-overdue go at a high school problem, then write it up for 3/14. This didn't get started quite that way, but it's in the same spirit. #mathstodon

I only understand computation as the MANIPULATION OF ABSTRACT PLATONIC FORMS. I do not understand this realm where computers are "physical objects" you manipulate with "screwdrivers". I would prefer to use Math to translate my thoughts directly into action, as if I am casting magic spells

@Pineywoozle absolutely. And the stark geometry really is set off by decay. My whole rather rigid composition style is all about pitting geometry against things that rebel against it.

@Anke @johncarlosbaez If you want to be able to customize your triangle graph paper with different sizes, colors, etc., without using a web site, then @mcnees and I have you covered! We wrote a LaTeX package named gridpapers, available at https://github.com/mcnees/LaTeX-Graph-Paper or in any LaTeX distribution since ~2022.
GitHub - mcnees/LaTeX-Graph-Paper: Make your own quadrille, graph, hex, etc paper! Uses the pgf/TikZ package for LaTeX, which should be part of any modern TeX installation.

Found on my bookshelf: Cybernetics, Simulation, and Conflict Resolution. Third Annual Symposium of the American Society for Cybernetics

I bought this 1971 conference proceeding for 39 cents from a close out retailer somewhere between Manchester and Nashua, NH probably around 1980.

Includes: “Gaming and planning for campus crises”, “Modeling the dynamics of warfare”, “Some future social repercussions of computers”

Barath Raghavan and Bruce Schneier argue that the CrowdStrike outage “is yet another reminder of how brittle global internet infrastructure is. It’s complex, deeply interconnected, and filled with single points of failure.” https://www.lawfaremedia.org/article/the-crowdstrike-outage-and-market-driven-brittleness
The CrowdStrike Outage and Market-Driven Brittleness

The outage is another consequence of companies’ sacrifice of resilience for expediency.
