Computer Science | Grinnell College

The Computer Science Department welcomes two new faculty this year:

Nicole Eikmeier

Professor Eikmeier joins us from Purdue University, where she recently finished her PhD dissertation in the field of network analysis and random graph models. During her first year, she will teach Functional Problem Solving (Data Science) and Analysis of Algorithms.

Shervin Hajiamini

Professor Hajiamini joins us from Washington State University, where he recently finished his PhD dissertation titled Optimality study of dynamic voltage/frequency scaling in fine-to coarse-grain island partitioning for multicore systems. During his first year, he will teach Object-Oriented Problem Solving, Data Structures, and Algorithms and Operating Systems and Parallel Algorithms.

We are excited to have these outstanding faculty members joining the department.

May 7 CS Table location: JRC 224B, noon.
This is the last CS Table of the semester.

The last topic will be something a little less serious than our usual CS Table material: estoteric algorithms. We’ll spend the hour looking at algorithms (and data structures) that are intentionally inefficient or amusing. For example, this classic XKCD comic introduces five different esoteric sorting algorithms.

We will have a few algorithms and data structures prepared, but we would like your suggestions, too! Please send suggestions to Prof. Curtsinger by email, preferably by the end of the day on Monday, May 6. Please include a code or pseudo-code snippet we can show on the projector during our discussion.

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 12:00–12:50pm. Most CS Tables for the spring semester will meet in JRC 224B inside the Marketplace, though a small number will be in an alternate location, so watch each week for the location. 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 (sign in at the Marketplace front desk).

Recently, Facebook announced that it will be partnering with the Social Science Research Network to provide anonymized Facebook data to Social Science Researchers. This week in CS table, we will discuss some related issues with big data and anonymity.

Eric S. Raymond’s "The Cathedral and the Bazaar" is a classic essay on software development and open source communities. This writing was later turned into a book, but the original essay (with some later additions) is available online.

The full essay is a bit longer than some of our regular readings for CS Table (around 18 pages), but it is still a fairly quick read. You can find the essay at: http://www.catb.org/~esr/writings/cathedral-bazaar/cathedral-bazaar/.

If you are interested in how this essay was received, you may enjoy reading some of the responses to this essay under “Commentary and Argument” on this page: http://www.catb.org/~esr/writings/cathedral-bazaar/.

Let's look at an important case study in safety-critical software: the Therac-25. This was a device built to administer radiation to patients under carefully controlled conditions, but the device suffered from a critical flaw that made it possible for patients to receive dangerous levels of radiation instead of the carefully-controlled doses the machine was designed to administer. We’ll explore what went wrong, and discuss the lessons learned (or not learned) from this case.

The reading this week is The Story of Mel: a classic short story about a "real programmer" to give you some historical perspective on computing. There will probably be terms that aren't familiar to you, such as "drum memory," "core memory," and "machine code." While the faculty can provide some context during the discussion, we recommend that you do a bit of delving into strange terms in advance.

At CS Table we will discuss the innovation (or lack thereof) driven by technology companies, guided at least in part by a critique of Google’s "moonshots" that appeared in Communications of the ACM: Thomas Haigh. 2018. Hey Google, What's a Moonshot?: How Silicon Valley Mocks Apollo. Communications of the ACM 62, 1 (December 2018), 24-30.

At CS Table we will discuss Massive Open Online Courses (MOOCs).

To prepare for our discussion, please read the selection of short articles that appeared in Communications of the ACM in late 2012, and one of the many retrospectives on MOOCs that has appeared more recently. All of the articles are brief, but contain many links to outside sources. You are encouraged to read all of these articles and explore some of their links, but any subset of these articles would be helpful for you to prepare for our discussion.

• Will Massive Open Online Courses Change How We Teach?
• Will MOOCs Destroy Academia?
• In the Year of Disruptive Education
• Research Questions About MOOCs
