The Baltimore ACM Chapter, the Greater Baltimore Technology Council, and the Emerging Technology Center are hosting a free, public lecture on entrepreneurship by David Turock at 7:00pm, Wednesday 27 April in the ETC Canton facility (2400 Boston St., Baltimore).

David Turock will present a side-by-side comparison of two telecommunications start-ups that he launched: one successful, and one not. He compares and contrasts their funding sources, agility and scalability of their business models, hiring practices, and more. His experience and lessons learned will be valuable for aspiring tech entrepreneurs. He finishes with how his interests have shifted to using technology to promote social and environmental causes.

David Turock is a veteran entrepreneur and currently a Director of Counsel RB Capital. He holds a patent on VoIP, and is an expert on telecommunications technologies and their applications. Mr. Turock began his career working with AT&T Bell Laboratories in 1982 and Bell Communications Research in 1988, and subsequently founded enhanced telephone service provider, Call Sciences. He later formed Interexchange, which designed and operated one of the world's largest debit card systems. Most recently, from 2001 to 2007, Mr. Turock was Chief Technology Officer of Therap Services, a provider of informatics services to disabled patients. Mr. Turock received his B.S. in Experimental Psychology from Syracuse University, his M.S. and Ph.D. degrees in Cognitive Psychology from Rutgers University, and his M.S.E. in Computer Science from the Moore School of the University of Pennsylvania.

The Baltimore ACM chapter invites attendees for pizza starting at 6:30pm. There is no charge, but please RSVP to Emil Volcheck at Sorry, you need javascript to view this email address.

The ETC Canton facility is located at the American Can Company complex, 2400 Boston Street in Baltimore. ETC is on the 3rd floor of the building that houses the Austin Grille restaurant and the entrance is next to the Lenscrafters store. There is a 3 hour visitor parking in front of the building on the Boston Street side.

The CRA reports that total enrollments among U.S. computer science undergraduates increased 10% in 2010 based on data from its most recent annual Taulbee Survey. This is the third straight year of increases in total enrollment and indicates that the post “dot-com crash” decline in undergraduate computing program enrollments is over. The Taulbee Survey is conducted annually to document trends in student enrollment, degree production, employment of graduates, and faculty salaries in Ph.D-granting departments of computer science, computer engineering and information systems in the United States and Canada. You can find the data in a CRA report on Computing Degree and Enrollement Trends.  The full data from the Taulbee report will be available later in May from the CRA Web site.

The data for UMBC computing majors shows similar increases in the past three years.

We are a group of students who are performing a research study to investigate how students learn and improve their performance at different aspects of Python programming. For the study, we are looking for students who are currently enrolled in CMSC 201 or who took CMSC 201 in the last semester or two and have not yet completed CMSC 202.

In exchange for your participation in the study, we will provide pizza for the participants, and each student will also be entered into a drawing for an 8G iPod Nano, in the color of your choice. One participant, of the 24 to 32 students that we recruit, will win the Nano.  We are currently signing students up for the following three time slots:

• Wed 4/6, 7pm-10pm: free pizza will be available for registered participants at 6:45
• Fri 4/8, 10am-2pm: Show up *any time* between 10am and 2pm — whatever works for you! Pizza will be ordered around noon.
• Mon 4/11, 10:30am-8pm: Show up any time between 10:30am and 8pm! Pizza will be provided around noon and again around 6:30 if there are participants there to eat it!

The study will take place in ITE 240. Please sign up in advance if at all possible, and let us know what time you expect to arrive during the open sessions, so that we know how many students to expect and how much pizza to order!

The study involves four stages: first, you will be given a brief tutorial in the Python-based RUR-PLE visual programming environment and be asked to answer some warm-up questions to help familiarize you with the RUR-PLE environment. You will then be given a pretest that asks you to answer some basic multiple-choice programming questions. Next, you will be given a series of problems to solve within RUR-PLE, either by writing Python programs to perform a specified task, or by predicting the output and behavior of a given program. Finally, you will take a posttest that is similar to the pretest. We will record your answers to help us understand how to predict student programming performance and learning, based on their starting knowledge. The length of time to complete these tasks will vary, depending on the student, from one to two hours. Your data will be completely anonymized, and no information about you personally will be stored with the results of the study.

If you have any questions or wish to volunteer for the study, please contact Amy Ciavolino at Sorry, you need javascript to view this email address. Prof. Marie desJardins (Sorry, you need javascript to view this email address. ) is the faculty advisor for this project, and you may also contact her with any questions or concerns.

The Social Life of Personal Information

Dr. Manuel A. Perez-Quinones

Associate Professor of Computer Science
Virginia Tech

1:00pm Thursday 14 April 2011, ITE 325b

Personal Information Management (PIM) practices are the set of behaviors that we follow to organize our information. This often includes the management of email messages, documents, bookmarks, digital pictures, music, etc. Research in PIM has identified a core set of set of behaviors: encountering information, deciding to keep the information, filing/archiving, and reusing the information. The plethora of digital information and online transactions has us struggling to manage information effectively. In my research group, we are exploring how we can help address this problem.

In this talk, I briefly present previous work on PIM and highlight some new projects that my research group is exploring at the intersection of PIM and Social Networks. The rise of social networks presents an opportunity for the management of personal information. Emails in a person's inbox, for example, are "shared" between the sender and the receiver. What if we could share the PIM practices within our inner personal circle? Could we leverage the power of our social network to be more organized?

Enabling Reproducibility of Scientific Data Flows
through Tracking and Representation of Provenance

Curt Tilmes

10:00am Thursday, 31 March 2011
ITE 325b, UMBC

Reproducibility of results is a key tenet of science. Some modern scientific domains, such as Earth Science, have become computationally complicated and, particularly with the advent of higher resolution space based remote sensing platforms, tremendously data intensive. Over the last few decades, these complexities along with the the rapid advancement of the state of the art confound the goal of scientific transparency.

This thesis explores concepts of data identification, organization, equivalence and reproducibility for such data intensive scientific processing. It presents a conceptual model useful for describing and representing data provenance suitable for very precise data and processing identification. It presents algorithms for creating and maintaining precise dataset membership and provenance equivalence at various degrees of granularity and data aggregation.

Application of this model will allow more specific data citations in scientific literature based on large datasets and data provenance equivalence. Our provenance representations will enable independent reproducibility required by scientific transparency. Increasing transparency will contribute to understanding, and ultimately, credibility of scientific results.

CSEE Professor Samuel Lomonaco is the co-organizer of a two-day workshop on Topological Quantum Information to be held on May 16-17, 2011 at the Mathematical Research Center Ennio De Giorgi in Pisa as part of an intensive research period focused on Knots and Applications. The workshop will foster inter-disciplinary communication among researchers working on topological information science.   A goal is to identify key issues involved in ultimately building a quantum computer based on a quantum system with inherently built-in topological obstructions to decoherence.

Still looking for a summer internship? Check out the Google Summer of Code (GSoC).

This is a is a global program funded by Google that pays undergraduate or graduate students a $5000 stipend to write code for open source projects. GSoC has worked with the open source community to identify and fund exciting projects for the upcoming summer. The FAQ is a good place to find out more.

A set of open source projects (aka mentoring organizations) has been selected. Students apply to work on one of more of these and each mentoring organization ranks the students interested in working with them. Google facilitates the final selection and pairing. The mentoring organization works closely with the student to define tasks, check progress, help solve problems, etc. Typically the thudent works remotely, interacting with his or her mentor via email, chat, skype, etc.

Students can submit applications via the Google Summer of Code 2011 site from March 28 to April 8. Google says that that the best applications they receive are from students who took the time to interact with one of the participating mentoring organizations and discuss their ideas before submitting an application. Check out the information on the Advice for GSoC Students Page which links to a list of the 2011 mentoring organizations.

I have a plug for a particular project: Elgg. "Elgg is an award-winning social networking engine, delivering the building blocks that enable businesses, schools, universities and associations to create their own fully-featured social networks and applications." One of the people involved with Elgg's GSoC effort works at JHU/APL and may do mentoring locally. They are looking for people who know (or are willing to learn) PHP, JavaScript, and basic web development. Send email to Sorry, you need javascript to view this email address. to find out more about the ideas the Elgg project has proposed for GSCO 2011.
