I have a hard time keeping these terms straight:
- liveness vs. safety
- soundness vs. completeness
This is intended as a short guide for myself; maybe someone else will find it useful too! Note that this is all to the best of my knowledge and understanding at the present time; if there be faults, they be the faults of myself. I welcome correction and clarification if I am wrong.
Liveness vs. Safety
#
Liveness and safety deal with properties of a system. Contrast that with soundness and completion, which are adjectives about analyses.

A collection of what worked well and what didn’t in classes that I took this semester. This is partially for me to record what things reduced friction for me as a student so that one day, should I become a professor, I’ll be able to run the lowest-friction class ever!

The following is from a essay from a class on German literature and film.
Fritz Lang’s movie Metropolis is primarily about the struggle between the oppressed working class and the ruling elite. What drives this tension, however, is a particular view of technology and technological progress that exacerbates the problems the film focuses on. This mentality is called high modernist ideology by Scott in his book Seeing Like a State:

What does this program do? At the most reduced level, one could say that a program’s behavior is defined by the effect it has on the hardware running it. That’s not very useful however; when we’re programming, we often have to deal with legacy code and tease out the original intent of the code.
Saying that the meaning of a program is entirely encapsulated by the code is saying that the intent and the implementation are the same. They so rarely are!

Last week I was studying outside of a lecture hall where someone was teaching an introductory course on computer programming. There was a lot that I overheard that I disagreed with; this essay is an attempt to help me crystallize what exactly I disagreed with.

My wife and I got a chance to go to a place that lets you paint pottery and then have it fired. The pottery is all pre-made; you just get to paint it.
It’s been a very long time since I’ve worked with a physical art medium, so the mug looks kinda dumpy. I did alright with the Racket logo on the bottom-inside of the mug though!

When I get a little money I buy books; and if any is left I buy food and clothes.

Control-Flow Analysis is a popular technique for performing static analysis of many different kinds of programming languages.
It’s most often needed in cases where you have some kind of dynamic dispatch: either where you have first-class functions or when you have objects and you call one of their methods.

For one of my classes I am required to take a short weekly exam via Proctorio. There’s been some controversy surrounding this software. Although it claims it’s trustworthy, it’s not open-source, so no one can verify their claims. So naturally, I was reluctant to install it on my primary machine. Enter: the spare raspberry pi I have sitting around.

This is the story of how I managed to get FreeBSD running on a Raspberry Pi 4 with 4GB of RAM, though I think the setup story is pretty similar for those with 2GB and 8GB.
I also managed to get Rust built from source, (kind of) which is nice because the default Rust installer doesn’t seem to work for FreeBSD running on a Raspberry Pi.
