CS Table 11/21/17: Games and the Gig Economy

At the November 21 CS Table, we’ll be discussing the phenomenon of the Gig Economy—an economy characterized by independent workers contracted for short-term jobs—and how recent developments in technology have supported this new economy. The most famous of these is Uber, and in particular, we’ll look more closely at how Uber uses data science and psychology in tandem with mobile technology to power its driver networks (for better or worse). Please read this pair of meaty (but intriguing!) articles:

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 224A (inside the Marketplace). 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 JRC front desk).

Thursday Extra 5/5: Increasing Access to STEM for Blind Students

Catie Baker from the University of Washington will talk about increasing access to STEM for blind students.

Thursday, May 5, 2016
4:15 pm in Science-3821
Snacks at 4 in the CS Commons.

This talk will focus on two of Baker's research projects. Tactile Graphics with a Voice (TGV) proposes an alternative to Braille labels on tactile graphics. Many people who are blind do not know Braille, and Braille is often too large to fit on the graphic anyway, so Baker's team proposes using QR codes instead, which can be read aloud by smartphones. They created a smartphone app which can provide guidance to a blind user to help them scan the QR codes. Baker will also present StructJumper, an Eclipse plugin which creates a hierarchical tree based on the nesting structure of a Java class. As screen readers are linear in nature, it can be difficult for a blind programmer to quickly skim or move around in the code. StructJumper presents a new way for blind programmers to navigate the code using its structure.

Thursday Extra on 11/12: Mobile Sensing Applications

Octav Chipara will present "Developing and Deploying Mobile Sensing Applications."

Thursday, November 12
4:15 pm in Science 3821
Refreshments beforehand in the CS Commons

Octav Chipara is an Assistant Professor in the Department of Computer Science at the University of Iowa and part of the Aging Mind and Brain Initiative.

Mobile sensing applications are an emerging class of mobile applications that take advantage of the increasing sensing, computational, storage, and networking capabilities of mobile devices. Chipara's research focuses on the systems, networking, and software engineering aspects of developing mobile health (mHealth) systems that continuously monitor and infer the health status of patients. His work combines the design of communication protocols, middleware, and programming tools with large-scale real-world deployments of working systems.

In this talk, Chipara will describe AudioSense – a novel mobile sensing application that allows audiologists to assess the performance of the hearing aids in the real-world. A key limitation of traditional laboratory and survey methods employed by audiologists is that they fail to predict when a hearing aid user will be dissatisfied with its performance in the real-world. In contrast with these techniques, AudioSense jointly characterizes both the user's auditory context and the performance of the hearing aid in that context. The second part of the talk will cover some of the tools his team has created to simplify the development of mobile sensing applications. The focus is one of coordinating when different hardware resources (e.g., WiFi, 3G) are turned on and off to save energy without hindering user experience. A lightweight annotation language and middleware service will be presented that can be used to build energy-efficient mobile sensing applications for Android.

Thursday Extra: IBM Watson and Innovation in NYC

October 8
4:15 pm in Science 3821
Refreshments served at 4:00 pm in the CS Commons.

Blake Creasey '16 will present: "IBM Watson & Innovation in New York City."

This summer I went to New York City for seven weeks to learn about IBM Watson and engineering entrepreneurship at the Cooper Union. Our IBM mentor taught us about the brand of Watson, how pieces of the technology work, and current implementations of the technology. We met with our client, the New York Public Library, to understand a problem in their book recommendation system, and we set out trying to use the Watson Experience Manager to build a solution. We interviewed potential users, reviewed existing survey data, extensively discussed technological feasibility, met with current IBM Watson business partners, and finally built an iPhone book recommendation application using IBM Watson's natural language processing capabilities. My main focus in this talk will be on IBM Watson and our prototype iPhone application, Shelf. I will also briefly discuss the companies that I toured-Google, Bloomberg, Microsoft, Gamechanger, IBM Watson's Experience Center-and the meetups that I attended. Thanks to the Wilson Program, I hope to share what I learned about innovation, and I hope to discuss my general impressions on what is happening with innovation-the cool, the incredible, the scary, and the future.

Wednesday Extra: "Grinnell AppDev"

On Wednesday, February 5, Maijid Moujaled 2014, Colin Tremblay 2014, Lea Marold Sonnenschein 2015, and Patrick Triest 2015 will discuss the work of the AppDev Team, in developing and implementing a training program for students interested in designing and/or developing mobile applications.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, “Grinnell AppDev: Building community for mobile development,” will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Thursday Extra: "Mobile computing for social good"

On Thursday, January 30, Spencer Liberto 2015 will report on the work of his summer 2013 research team:

Over the course of the summer, a group of students worked with Professor Sam Rebelsky to redesign the CSC 207 curriculum. Our goal was to create a curriculum that was a more natural successor of the first two introductory courses in the sequence, by engaging the students with motivational tools and a core theme they could relate to. We achieved that by building the curriculum around Android development, to provide students with tangible end-of-course projects to call their own, and tying it all together under an overarching theme of social justice.

Refreshments will be served at 4:15 p.m. in the Computer Science Commons (Noyce 3817). The talk, “Mobile computing for social good in CSC 207,” will follow at 4:30 p.m. in Noyce 3821. Everyone is welcome to attend!

Grinnellians attend hackathon

From the September 27 edition of the S&B:

"Last weekend, a group of seven Grinnell students went to the annual MHacks “hackathon” event, organized by the University of Michigan. This was the first time students from Grinnell participated in such an event as a group. With approximately 1200 participants from over 100 schools across the country, this was the biggest hackathon of the year."
