Now they meet downtown. I have no other reason to be there, I don't drive, barely walk, and am afraid of air. I should be writing a program that works, but instead…
This page contains what is left of the presentations I made to the WLUG. (Some of it has been changed or deleted over the years.)
The day comes. I try to log on jit.si at 7pm. … Waiting for moderator. Try log on without one, it presents three choices: Facebook, Google, Github.
Epic fail. I finally get into the meeting about 20min late. They are talking about something to replace Twitter (the formerly known web site). To me, that's like asking for a replacement for poison ivy. I never touch it.
I rudely interrupt and try to present my slide show, but screen sharing does not seem to work like it did last time. I want share my whole screen. I think I did that last time. The plan was to demo the program by showing slides in one window, an emacs instance with TeX source in another, a shell prompt from which I can show how to run the program in another, and the result in another.
I didn't take notes, and don't remember exactly what happened, but I think when clicked the "share screen" it popped up a two item menu with something like "share whole screen" or "share one window", but the "whole screen" choice was dimmed and nothing happened when I clicked it. I could only share a web browser window.
I can't edit and run programs in a web browser. The slides were made to go with that planned demo; they aren't worth much without it, but here they are:
PDF Slides
and here is the souce code:
LaTeX source for Slides
I don't remember where I got it. The file on my machine is dated 2011-Jun-10. It's probably a copyright violation, and it's bigger (408K) than the average cartoon, so keep it on the down-low.
I thought of re-compressing it to save bandwidth, but I think there might be jokes that I don't get written on the post-it notes stuck around the screen. Take your copy for personal use, zoom in, and let me know if you see anything funny.

At least since Ken Thompson's Turing Award Lecture "Reflections on Trusting Trust" it has been known that (by Kleene's Recursion Theorem) it is possible to put a trojan horse into a compiler in such a way that it can neither be seen in the source code of the compiler, nor removed by re-compiling the compiler.
I made a presentation for the Worcester Linux Users Group (WLUG) last year. I continue to think about these things. I'll let you know when I make notable progress.
Update (2024-11-23): Obviously that was written in 2020, the year it all fell apart. The presentation was done at WPI. I made the slides for the 2024 November presentation by copying and changing these. I was worried for a while that it would be too repetitious, but students who were there are now graduated. In 2019 I used LaTeX; in 2024 I talked about it. Doug Waud did a presentation on TeX, but the undergraduates now weren't born then. Repetition is good and it is good to review again.
I made some slides using LaTeX to produce PDF files and showed the webpage of the source-only bootstrap project.

Then I did a demonstation of these programs:
A self-reproducing C program
Polyhedronism
