Syllabus

CS 4110, “Programming Languages and Logics,” is a thrilling amusement-park ride through the beauty and glory of programming languages, the theory behind them, and their implementation. It will not be easy, but you will achieve a clear and rigorous understanding of computing: a rare enlightenment that will give you great power.

TL;DR

Organization

Announcements and Q&A: Campuswire

We will use Campuswire for announcements and communication about the course. (We’re using Campuswire instead of Piazza.) Sign up for an account there with your netid@cornell.edu email address. That should give you access—if not, please email Adrian for a secret code. The course staff will post important updates there that you really want to know about! Check often, and be sure to enable notifications for the #announcements channel.

You can also ask questions—about lectures, homework, or anything else—on Campuswire.

If you can answer a question yourself, please do! But be careful not to post answers—if you’re not sure whether something is OK to post, contact the course staff privately. You can do that by creating a note that is visible only to “Instructors and TAs.”

A good post asks a specific question. Here are some examples of bad posts:

If you need help with a homework problem, for example, be sure to include what you’ve tried already, exactly where you’re stuck, and what you’re currently thinking about how to proceed. If you just ask for help without any evidence of effort, we’ll punt the question back to you for more details.

Assignments: CMS

You will download homework assignments, upload solutions, and receive grades through CMS. Please log in there to see whether you’re in the system. If you’re not, please send your NetID to the course staff and we’ll get you set up.

We’re using an anonymous grading system, i.e., we won’t know who we’re grading. So please do not put your name or NetID anywhere in the PDF you upload to CMS. (CMS knows who you are!)

Content

We won’t use a textbook, but if you like books, we have some resources to suggest.

Grading

Final grades will be assigned with these proportions:

There is no algorithm for “curving” grades nor any predetermined cutoffs, so we won’t be able to answer questions about letter-grade projections.

Problem Sets

Problem sets are due on Wednesdays at 11:59 PM. See the course schedule. You can work on problem sets with a partner; you’ll turn in one completed assignment together.

We will drop one score to calculate your final grade: that is, your lowest-scoring problem set won’t count, even if that score is zero.

You’ll turn in assignments via CMS. We strongly encourage you to use TeX, but you can also write up answers by hand. If you do, scan your work and upload it as a PDF. It’s your responsibility to make sure scans are 100% legible—we won’t regrade work that was too hard to read.

Timeliness

You have three slip days that you can allocate to problem sets throughout the semester. When you use a slip day, it lets you turn in the assignment 24 hours late without penalty.

Aside from that, late work will not be accepted and will count for zero points.

Exams

There will be two in-class preliminary exams and a final exam. See the course schedule.

Makeup exams must be scheduled within the first three weeks of class. Check the schedule now to see if you have a conflict with another class and contact the staff immediately to reschedule.

Participation

To get full credit on the 5% of your grade allocated to participation, you just have to do three things:

Free points!

The Difficulty You Can Expect

This is an advanced course, so some things will be different from other classes you have taken:

Grading on both homework and exams will intentionally focus on nitpicky details. Compared to other courses, we will give more weight to “small” mistakes and less weight to getting the general idea right. That’s the nature of this course, which is about formalism. Often, the intuitive idea behind a problem is totally obvious! Then, the topic we’re working on is 100% about getting the nitty-gritty formal details right so we can prove something beyond a shadow of a doubt.

Policies

Academic Integrity

Absolute integrity is expected of all Cornell students in every academic undertaking. The course staff will prosecute violations aggressively.

You are responsible for understanding these policies:

You can also read about the protocol for prosecution of violations.

On problem sets, everything you turn in must be 100% completely your own work (with your partner, if you have one). You may discuss with other students about requirements for the assignment, programming in OCaml, etc. But when it comes to developing specific answers or coding, you may not talk to other students except for your partner or anyone else. Specifically:

Here’s the policy for exams: you may not give assistance to anyone or receive assistance of any kind from anyone at all (outside of the course staff) during an exam. All exams are closed book.

You may not give any hints or post any code that might be part of a solution on Campuswire (except in a private thread with course staff). On both assignments and exams, the web is always off limits: you may not Google anything or look anything up on Wikipedia to get help, for example.

Respect in Class

Everyone—the instructor, TAs, and students—must be respectful of everyone else in this class. All communication, in class and online, will be held to a high standard for inclusiveness: it may never target individuals or groups for harassment, and it may not exclude specific groups. That includes everything from outright animosity to the subtle ways we phrase things and even our timing.

For example: do not talk over other people; don’t use male pronouns when you mean to refer to people of all genders; avoid explicit language that has a chance of seeming inappropriate to other people; and don’t let strong emotions get in the way of calm, scientific communication.

If any of the communication in this class doesn’t meet these standards, please don’t escalate it by responding in kind. Instead, contact the instructor as early as possible. If you don’t feel comfortable discussing something directly with the instructor—for example, if the instructor is the problem—please contact the advising office or the department chair.

Special Needs and Wellness

We provide accommodations for disabilities. Students with disabilities can contact Student Disability Services at 607-254-4545 or the instructor for a confidential discussion of their individual needs.

If you experience personal or academic stress or need to talk to someone who can help, contact the instructor or:
