For me to get a sense of horniness seems to be concurrent with, and as uncertain as, getting a sense of my muscles.

"Pain in the subjective sense is what I want"
Ropes suspend me face-down, from a bamboo pole, by my chest and two thighs. However, the upline from my right thigh seems to be being dismantled by the rigger, who is standing behind me and smiling. This photo is taken from my rear left and shows my legs, butt, and torso, including a tattoo of rope on my left thigh. My arms are tied behind my back. My legs are lowered towards the floor: my left ankle has rope marks whereas my right ankle has a loose rope cuff. I'm naked. The setting is grungy industrial.Ropes suspend me, facing sideways, from a bamboo pole by my chest and left thigh. My left ankle is also attached to the pole, high up, whereas my right leg is lowered towards the floor, so my legs are wide open. A rope collar is tattooed on my left thigh, closer to my torso than the physical rope collar on my left thigh that's holding up half of my weight. My right thigh also has a physical rope collar but it leads loosely to the floor. My arms are tied behind my back. My butt is facing the camera. The rigger is standing in the back and looking to my left calf. I'm naked. The setting is grungy industrial.I'm crouching.

The setting is grungy industrial.I'm standing facing the camera, and the last bit of rope is being removed from me by the rigger standing behind me. His hands are raised and he is looking at me. My eyes are closed and my head is tilted towards the last bit of rope. My arms are still behind me. Rope marks are visible on my chest, upper arms, thighs, and ankles. I am naked and my chastity cage is visible. The setting is grungy industrial, with several hanks of rope hanging on metal frame to the side.

Hello Miriam Posner,

I hope you’re doing well.

My name is Aileen, and I’m the founder and organizer of Boozy Bronx Book Club, a 1,400+ member in-person reading community in New York City centered around thoughtful, high-engagement discussions.

I recently came across Seeing Like a Supply Chain, and was especially drawn to its exploration of technological systems of distribution. What stood out most was structural back-end shipping tracking, which feels like the kind of nuance that naturally sparks layered and honest conversation in our group.

Are gays allosexual? “I would have thought that that was the one thing a gay had to be.”
The first page of “Are Lesbians Women?” by Jacob Hale.
Hypatia vol. 11, no. 2 (Spring 1996)

Abstract: I argue that Monique Wittig’s view that lesbians are not women neglects the complexities involved in the composition of the category “woman.” I develop an articulation of the concept “woman” in the contemporary United States, with thirteen distinct defining characteristics, none of which are necessary nor sufficient. I argue that Wittig’s emphasis on the material production of “woman” through the political regime of heterosexuality, however, is enormously fruitful for feminist and queer strategizing.

Last sentence: Thus, one of my gay students initially responded by saying, “I would have thought that thatThe second page (95) of “Are Lesbians Women?” by Jacob Hale.

The course evaluations are in! (Upper-level programming languages)
What did you like most about this course and instructor?
I really liked the class. Engaging professor, interesting content and hw.
The availability of help on Discord! Without it, this course would have been MUCH MUCH more difficult.
There was clear consistency throughout the course. Each lecture built on previous lectures, as did the homework assignments, allowing students to build confidence and a sense of understanding throughout the semester. Lectures were entirely live coding, so learning was all one big example, making it easy to picture applications for concepts taught in class.
Professor Shan was very passionate about this field and it reflects how he teaches this course. He is always very willing to help, and always made it clear that he wants to see his students succeed.
He was passionate.What did you like least about this course and instructor?
I thought the two exams were harder than the practice ones and sometimes didn't feel entirely reflective of if you knew the concept. I still think they did a decent job evaluating it and really liked the class.
N/A
Day 1, a Reddit post was handed out which was posted by a previous student warning other students about the difficulty of this class and warning against enrolling in it if possible. This caused unnecessary anxiety and misrepresented the class's true level of difficulty and week to week activities. I get the sense it caused some students to lose some hope early on, affecting their performance.
The lack of structure for each lecture sometimes made it hard to follow along and learn. We would just jump into content without really knowing what we would be going over, and this made it very easy to miss important information. Sometimes it was difficult to tell what the main takeaways of a lecture were. Lectures would often just be a lot of information thrown at you all at once, and because the structure of each lecture is messy it made it hard to take notes and hard to follow along.
This feedback is not directed at the instructor personally, but rather at the structure and expectations of the class as a whole. In most cases, course descriptions provide a reasonably accurate sense of what the class will cover. Unfortunately, that was not the case here…What could the instructor do to improve the course or his/her teaching effectiveness?
Table for [QTitle].
Comments
Not sure. I thought it was very effective. biweekly quizzes might be helpful to incentivize pepople to study the concepts more and review.
N/A
Slightly more context when introducing new concepts or when making references to old concepts or concepts outside the scope of the class to help illustrate points. Those seemed to be more relevant to some students than others.
Give students a bit more information on how each lecture is going to be structured, for example, maybe a quick slide deck at the start of each lecture or a roadmap that described the topic of the lectures. I think I would have learned more effectively if the goal of each lecture was more clearly defined to the students.
From my perspective, the instructor could benefit from recognizing that this is not exclusively an honors–level class… Additionally, it sometimes felt as though criticism of the course was treated more as a challenge than as feedback to consider… The testing structure was another major concern… Overall, clearer communication about expectations, exam content, and the intended level of difficulty would go a long way toward improving the experience for students in this course.Any advice for future students?…
Regular review on top of hw is helpful before the exams.
Ask how Racket formatting works with match, cond, etc. In fact, ASK QUESTIONS ABOUT EVERYTHING!…
Go to every lecture. Be sure to save enough time during the week to struggle with the homework assignments. Go to office hours!
Reserve a lot of your time for the semester for just this class…
If you find early in the semester that you are not fully understanding the core concepts, I would strongly consider seeking additional help immediately or reevaluating whether the class is the right fit at that time…

How did you use ChatGPT (or similar online code generating tools like Copilot or Claude) in this class? How did it affect your experience?
Not really allowed for the class so I didn't on anything directly class related. When first learning racket at the beginning I asked chatgpt to make some questions to quiz my understanding of core parts of racket, and sometimes more difficult ones, then to give feedback on my answers…
I'd rather eat live bugs for the rest of my life and die from poisoning than use ChatGPT, Copilot, or Claude…
I have tried to get it to explain concepts to me that I had trouble understanding, such as how environments work or how different types of interpreters function. Sometimes it helped, but sometimes it also made me more confused.
I frequently used tools like ChatGPT when I became stuck on assignments or concepts…
