Thursday Extras

Thursday Extra: Summer 2013 research projects

On Thursday, January 31, Professors Janet Davis and Sam Rebelsky will discuss summer student research in computer science, including the student projects that our faculty will direct this year.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The discussion will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Summer opportunities in computer science"

It's never to soon to think about what you're going to do next summer! While summer may seem far away, taking advantage of some of the better summer opportunities requires advance planning—for example, some programs have deadlines in January or February.

On Thursday, December 6, Professor Sam Rebelsky will discuss typical off-campus summer options available in computer science—research, internships, and more—and suggest strategies for developing your applications. (At a separate session early next semester, the CS faculty will describe summer research opportunities available at Grinnell.)

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). Professor Rebelsky's presentation will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "NoSQL"

On Thursday, November 29, Tolu Alabi will describe a widely used non-relational database. She writes:

NoSQL is a new database technology used to store large data. Instead of storing lots of data on one machine, data can be distributed across multiple machines, thereby reducing the load on a single machine. NoSQL is also used to replicate data across multiple nodes. If data is replicated across multiple nodes, one is no longer at the mercy of a single node. So if a single node dies, the data is still available and accessible from another node.

Many big companies have switched from the traditional SQL -like database to NoSQL-like database because of these two major reasons. Come to my talk to learn more about the advantages of using NoSQL.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, NoSQL, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Self-Disclosing GIMP with MediaScript"

On Thursday, November 15, Sarah Henney 2013 and Martha Fletcher 2015 will describe their summer internship work on the MediaScheme project:

Self-Disclosing GIMP(SDGimp) is an ongoing project with the goal of adding self-disclosure functionality tailored to the MediaScheme library into the GIMP. In short, SDGimp will allow a user to perform an action in the GIMP and then view the Scheme expression which can be used to duplicate that action.

In this Extra, we will discuss and demonstrate our work from this summer on SDGimp, including our expansion of the MediaScheme library to include more actions from the GIMP.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, Self-disclosing GIMP with MediaScript, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Technical internships"

On Thursday, October 18, Dilan Ustek 2014, Aditi Roy 2013, Tolu Alabi 2013, Maijid Moujaled 2014, and David Cowden 2013 will discuss the technical internships they have done at Microsoft, Amazon, Goldman Sachs, Pikuzone, and Iowa Health System. They will talk about their experiences at big technical companies, a start-up, and the IT department of a health organization. Come to learn about these various experiences and what to do in order to get them!

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, Technical internships, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Computational epidemiology"

On Thursday, October 11, Professor Alberto Maria Segre of the University of Iowa will discuss recent work on modeling and analyzing the incidence and geographical distribution of disease in human populations:

Computational epidemiology lies at the intersection of computer science, engineering, statistics, and health care. Our goal is to inform public and hospital policy decisions on topics such as disease surveillance, disease prevention measures, and outbreak containment.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, Computational epidemiology, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "GLEAM"

On Thursday, October 4, Jennelle Nystrom 2014 and Svea Drentlaw 2013 will discuss their summer work:

The Grinnell Livescripting Environment for Art and Music (GLEAM) is a Scheme library for the Microsoft Kinect camera that allows for collaboration between musicians and programmers. As a musician gestures, the programmer modifies how their gestures will affect the musical production in real time. In this Extra, we will discuss our work on GLEAM this summer and provide a short demo with the Kinect.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, GLEAM: the Grinnell Livescripting Environment for Art and Music, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Algorithmic arts"

On Thursday, September 27, Professor Sam Rebelsky will discuss the emphasis on the algorithmic construction and transformation of graphic images in our CSC 151 course:

We have transformed the introductory course in computer science to emphasize the construction and manipulation of images. Students work with a drawing application, creating images by hand and with “scripts.”

The capstone project for the course is A Procedure is Worth 1000 Pictures, in which students write a program that, given a width and height, can generate one thousand different but related images that meet particular guidelines. The project must meet both studio and computer science design criteria. We do studio critiques of both the aesthetic and computational aspects of the projects.

We are exploring ways to have students in this course collaborate with students in the introductory studio art course. One approach builds on a Modular Print project in the studio art course in which students build a square block that they then print in multiple rotations to achieve a more complex image. For the bridge activity, we expect that studio students can propose basic arrangements of the blocks, and CS students can build a program that helps the art students explore the design spaces those arrangements suggest.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, Algorithmic arts: bridging computer science and studio art, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Dynamic code generation and what it takes to get there"

On Thursday, May 3, Isaiah Sarju 2013 will discuss the nature, history, and theory of security vulnerabilities associated with dynamic code generation:

More specifically, the talk will deal with the underlying hacking techniques and security principles which have led to research into dynamic code generation: the history of memory vulnerabilities, the security mechanisms which are used to protect against these attacks, and the state of the art of bypassing these protections.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, Dynamic code generation and what it takes to get there, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Self-disclosing code"

On Thursday, April 26, Pelle Hall 2014, Andrew Hirakawa 2012, and Jennelle Nystrom 2014 will present the result of their work in summer 2011 on software that generates programs to duplicate the effects of operations that users perform in a graphical user interface.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, Self-disclosing code, will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!
