Cyber Security and Warfare in the 21st Century: Policy Conference

Date and Time
Friday, April 20, 2018 - 8:45am to 5:00pm
Robertson Hall, Arthur Lewis Auditorium

OPEN TO THE PUBLIC.  Please register at link here

Cyber capabilities have introduced new dynamics into national security planning, decision-making and strategy. Yet the uses, defenses and ramifications of these tools remain poorly understood. We hope you join us to learn more about these tools and how they impact national security.

The conference kicks off with a keynote on Thursday, April 19 at 4:30pm in Arthur Lewis Auditorium by J. Michael Daniel, President of the Cyber Threat Alliance and former Special Assistant to President Obama and Cybersecurity Coordinator. On Friday, April 20, we host panels of experts and policymakers to discuss cyber norms and governance, defense, and warfare and terrorism.

Princeton AI4ALL Planning Meeting

Date and Time
Thursday, December 7, 2017 - 4:30pm to 5:30pm
Computer Science Tea Room
Olga Russakovsky

Artificial Intelligence (AI) is rapidly changing the world. AI has amazingly broad applications, and we need people with a comparably broad set of experiences and worldviews working on AI problems. However, there is a distinct lack of diversity of people in the AI community, leading to a lack of diversity of thought. This results in technology biased for certain demographics, needs and values, accruing the benefits of AI to the few instead of the all.

The solution to the problem has to start with education. This coming summer, the Princeton Computer Science Department, the Princeton Center for Information Technology Policy, and the AI4ALL foundation are starting a summer camp to teach AI to high school students from underrepresented groups. The Princeton AI4ALL camp will run for 3 weeks, from  July 22nd - August 11, 2018. It will target rising 11th graders from racial/ethnic groups dramatically underrepresented in AI: Black, Hispanic/Latino/Latina, and Native American.

At this meeting, we will discuss the history of this initiative, describe what has been planned so far, and map out a plan going forward. There are lots of ways for you to become involved -- in paid and unpaid positions, in spring and summer, in teaching and research, in roles that require AI expertise and in roles that are most administrative in nature. The camp relies on undergraduate & graduate students, postdocs, researchers, faculty and staff working together to create an educational, memorable and inspirational experience for the high schoolers. We want to teach them basic AI concepts, showcase the broad range of AI applications, walk them through some of the AI policy issues, and instill in them the confidence that they too can become the future AI leaders. We need YOU to make this happen. 

Women's Interactive Networking Event (WINE)

Date and Time
Thursday, December 14, 2017 - 4:30pm to 5:30pm
Computer Science Tea Room
Olga Russakovsky

Details: The last event of 2017 will focus on mentoring. We'll begin with a short talk followed by small group discussions.

Food for thought before the meeting: What have you accomplished in 2017 that you're particularly proud of? (No, stop your mind before you start thinking of all the things you hadn't quite done perfectly. Really focus on one thing you ROCKED. And beam with pride.)

As always, open to graduate students, post docs and faculty of all genders!

Princeton ACM/IEEE- CS Chapters

The following "computer science in education" talk is part of our celebration of Computer Science Education Week (December 7-13, http://csedweek.org).

Colleges and universities need a good "introduction to computer science" for their students.  What should we teach and how should we teach it?  How should we use technology in an introductory course?

This talk describes a introductory computer science course at Princeton University.  The course has been under development for 25 years.  It is the highest-enrolled course at Princeton, attracting two-thirds of all students, preparing them all for further study in computer science (nearly 40% of all Princeton students are taking a CS course at any point in time).  The content is broad and deep, building on a solid foundation in programming to address fundamental issues in theoretical computer science and to also provide an overview of computer architecture, all in the context of interesting applications in science, engineering, and commerce.  The course is currently using a new textbook, extensive online content, and studio-produced lecture videos.

Robert Sedgewick is the founding chair and the William O. Baker Professor in the Department of Computer Science at Princeton and a member of the board of directors of Adobe Systems.  His research interests revolve around algorithm design, including mathematical techniques for the analysis of algorithms.  Prof. Sedgwick is the author of the very popular textbook "Algorithms, Fourth Edition" and other books on algorithms that have been best-sellers for decades.

On-line meeting notice:  http://PrincetonACM.acm.org/meetings/mtg1512.pdf

All ACM / IEEE-CS meetings are open to the public. Students and their parents are welcome.  There is no admission charge.
Refreshments at 7:30pm

Dropbox Tech Talk- Carousel's photo uploads and space saver

Date and Time
Tuesday, February 17, 2015 - 6:00pm to 7:00pm
Computer Science Small Auditorium (Room 105)

Dropbox's photo-sharing app Carousel's hottest new feature helps users free up space on their phone so they have room to download the latest iOS update or take more selfies. Kat Busch, an engineer at Dropbox and the creator of the feature, will talk about its design. The talk will cover Dropbox's Camera Uploads architecture (which has uploaded billions of photos) and how Carousel builds on that architecture to intelligently and safely clear space on users' phones.

We will have Dropbox Swag and lots of food. Please RSVP so we know how much to order!

We're also hiring software engineers for internships and full time positions! Feel free to bring your resume with you or to email it to caroline@dropbox.com if you're interested!
