CS Table 12/13: One Line Programs

At this CS Table we will run and decipher a collection of interesting one line programs. Short programs can be surprising, mind-bending, elegant, infuriatingly clever, or all of the above. We'll follow a relaxed format, where we will look at a new program, run it on a few examples, then try to figure out how it does what it does.

If you have any programs you would like to contribute, please send them to Prof. Curtsinger via email. All programming languages are welcome. We're happy to bend the definition of "one line" in many cases, but do try to stick to programs that are concise.

Computer science table (CS Table) is a weekly meeting of Grinnell College community members (students, faculty, staff, etc.) interested in discussing topics related to computing and computer science. CS Table meets Tuesdays from 12:00-1:00pm in JRC 224B. Contact the CS faculty for the weekly reading. Students on meal plans, faculty, and staff are expected to cover the cost of their meals. Visitors to the College and students not on meal plans can charge their meals to the department.

CS Table 11/29: Election Hacking

At this CS Table we will discuss a recent turn of events in the presidential election: election security experts are calling for recounts in several critical states. Why are they doing this, and why do we need to recount or audit our elections?

Read these three recent articles building up to this recent call:

In addition, to give you more background on the perils of voting and technology, read this paper by researchers at the University of Michigan, Ann Arbor about breaking into Internet voting systems:

CS Table on 11/22: CS Education Intitiatives

This CS Table will focus on two computer science education initiatives: CS Unplugged and code.org. These are interesting new approaches to getting computer science education into high school and grade school with some interesting goals. We'll start with a CS Unplugged exercise before the discussion!

There are three short readings suggested for the discussion on November 22:

CS Table 11/15: Algorithmic Bias

As computation plays a larger role in society, we are beginning to see cases where algorithms encode the biases of the past. While this phenomenon is widespread, there is a particularly interesting case where computer programs make bail recommendations for suspects in criminal cases.

There are two short readings suggested for the discussion on November 15:

CS Table 11/8: The State of JavaScript

On November 8 in CS Table, we will discuss the state of JavaScript, the language running inside your browser. This is a programming language that seemingly ignores virtually all of the wisdom garnered in programming language design over the last half century, and yet it has a huge devoted fan base and enormous impact worldwide. We'll talk about some of the amusing quirks in JavaScript, briefly dive into the world in which JavaScript developers must operate, and speculate about why JavaScript has still been so successful. As always, you do not need any experience with JavaScript to participate in this discussion.

CS Table 11/1: Echo Chambers

On Tuesday, November 1, 2016, we'll discuss what echo chambers are, their pros and cons, and how we ought to change our media consumption in light of them. An echo chamber in the context of media studies is a phenomena where the beliefs of a group are reinforced and amplified through repetition entirely within the group. Paradoxically, while the Internet promises to enable free speech and the transmission and sharing of ideas globally, some argue that it has only served to create silos for like-minded people to avoid interaction with dissenting opinion.

Readings: two short articles about echo chambers with respect to Facebook.

CS Table 10/11: The Intersection of Music and Computing

This week in CS table we’ll be exploring the intersection of music and computation along two dimensions:

  1. Computational Musicology: the analysis of musical structure from a statistical perspective, i.e., music informatics.
  2. Live Coding: the live performance of music using computer programs.

Computational Musicology. Along the first dimension, there are two readings:

The second reading is fairly dense and pre-supposes some knowledge of basic music theory. If you can get through the "Analysing the harmony” section where the authors describe their analysis technique for music, that would be grand. You may find that this recording of Hey Jude by the Beatles helpful to compare against: The Beatles - Hey Jude. Uploaded by TheBeatlesVEVO on youtube.com.

Live Coding. Along the second dimension, watch this TEDxNewcastle talk by Sonic Pi creator Sam Aaron on live coding: Sam Aaron. "Programming as Performance”. Uploaded by TEDx Talks on youtube.com.

CS Table 9/13: Data Privacy in Higher Ed

For the CS Table on September 13, Peter-Michael Osera would like to discuss data collection and privacy in a place we normally don’t consider: higher education. In efforts to streamline operations and better the student experience via data analytics, universities are frequently turning to the cloud for answers. Does this have implications for how we as students and faculty manage our data? Read these two articles:

Printed copies of the readings will be available after noon on Friday at Charlie Curtsinger’s office (Noyce 3827). In addition to the readings, there is a short “homework” activity to get you in the spirit of the discussion. Try to answer these brief questions:

  1. What FERPA is and how does it relate to your personal information? Read more about FERPA here: US DOE. "Family Educational Rights and Privacy Act (FERPA)”. http://www2.ed.gov/policy/gen/guid/fpco/ferpa/index.html
  2. Grinnell employs a number of third-party services that handle our (digital) data in various ways. List as many as you can.
  3. Why can these third-party services handle sensitive data that would otherwise be protected by FERPA? You can find the answer in this FERPA FAQ: US DOE. “FERPA Frequently Asked Questions (FAQ)”. http://familypolicy.ed.gov/faq-page#t62n218
  4. Completing this homework isn’t required to attend CS Table, but we will start the discussion by tackling these questions. So please come prepared if you have the time!

CS Table 9/6: Passphrases, MFA, and Security Hygiene

On Tuesday, September 6th, we will continue CS Table with a discussion of security practices, including the ongoing debate over passwords versus passphrases, multi-factor (or two factor) authentication, and general security practices. There are three short readings for this week:

CS Table 8/30: Meet and Greet; Content Planning

Tuesday we’ll begin CS Table anew for the semester! For those that are unaware, CS Table is the department’s weekly lunch-and-reading-group where we discuss current issues in technology and society. Everyone, irrespective of major, is invited to attend!

Our initial CS Table meeting will be a meet-and-greet along with content planning for the semester. If you have any hot topics that you’d like to discuss this semester, feel free to volunteer them up on Tuesday or email Charlie Curtsinger and Peter-Michael Osera with your suggestion.

This semester, CS Tables will be on Tuesdays, 12:00–1:00 pm, in JRC 224 B. Students on meal plans, faculty, and staff are expected to cover the cost of their meals. Students not on meal plans can charge their meals to the department.
