  • Discussion Groups for the Online Classroom (and Off)

    CSE and Cogntive Science professor Scott Klemmer (right) is one of the brains behind a new tool called Talkabout, developed at UC San Diego and Stanford and already deployed as part of Klemmer's massive open online course (MOOC) on human-computer interaction. Talkabout is a virtual discussion section built around Google Hangouts (which limits to nine the maximum number of participants in a Talkabout, or as few as two). Talkabout was built with Klemmer's former colleagues at Stanford, computer science professor Michael Bernstein and Ph.D. student Chinmay Kulkarni, and the project currently includes an incoming CSE M.S. student, Yasmine Kotturi (who graduates from UCSD in cognitive science this year). As originally implemented in Klemmer's first MOOC, the tool offered students the opportunity to log on any time, but students couldn't be sure that anyone else would be there at the same time.

    So instead, according to a report this week in Stanford Daily, "the new system works by randomly assigning a few people to each group. There is no moderator and students encounter new peers in each discussion section." Talkabout also allows students to choose between verbal discussion or contributing by text (which is often preferred by students for whom English is a second language).

    Talkabout has been used for many MOOCs. For example, CSE faculty-affiliate Terry Sejnowski recently used the tool for his Learning How to Learn MOOC on Coursera produced by the Temporal Dynamics of Learning Center. (The center is directed by CSE Prof. Gary Cottrell).

    An upcoming online courses set to use Talkabout for discussion groups is Learn to Mod, which teaches students how to code modifications of the wildly popular computer game, Minecraft. The instructor will be Sarah (Esper) Guthals (at right), a CSE alumna (PhD '14) and co-founder/CTO of the startup ThoughtSTEM, which develops courses, trainings, software and textbooks for children 8 to 18 to learn how to program. Guthals and ThoughtSTEM co-founder and CSE Ph.D. candidate Stephen Foster also created a video game, CodeSpells, to help teach kids programming skills. The research implementation was so successful -- attracting $164,000 from nearly 5,500 backers on Kickstarter -- that it is now under development as a full-scale commercial game by professional video game developers. Their success with CodeSpells led Guthals and Foster to develop LearnToMod software, which provides a game environment with puzzles and tutorials on how to craft "mods" in a browser, teaching how to code at the same time. That same software forms the basis of the "Learn to Mod" online course.

  • Alumnus Elevated to CEO at Games Company

    A former member of the CSE Alumni Board, Matt Shea (BS, Computer Science '97) has now become Chief Executive Officer at the games company, WildTangent, where he has worked for 13 years. Two years ago the Puget Sound Business Journal named Shea to its list of "40 Under 40" leading executives in the region where WildTangent is based (in Redmond, WA). The company makes the ORB device that converts a PC into a high-end videogame console, and WildTangent focuses on the distribution and monetization of mobile and online apps. Prior to becoming CEO, Shea was responsible for the company’s technology and product development, as co-creator of both the ORB game console and WildTangent’s WildCoins digital currency. Prior to WildTangent, Shea was engineering manager at InfoSpace's games group and engineering director for games at Go2Net, where he oversaw large-scale, online game sites including PlaySite, Lycos Games, and Hasbro’s Shea got his start in the games industry at Sony Interactive Studios, working on 3D graphics and massively multiplayer games while earning his undergraduate degree from CSE. 

  • Alumnus Reports on Advances in Encryption for the Cloud

    "Data Encryption in the Cloud: Square Pegs in Round Holes" is the title of a guest article by CSE alumnus Tom Ristenpart (PhD '10), on Information Week's DARK Reading information security website. In it, the computer science professor from the University of Wisconsin reports that conventional encryption is a surefire solution for protecting sensitive data -- except when it breaks cloud applications. The solution, he offers, is something called 'format-preserving encryption.' Ristenpart's research spans a broad range of computer security topics, focusing primarily on threats to cloud computing, as well as topics in applied and theoretical cryptography.

    In his May 21 article for DARK Reading, Ristenpart (at right) argues that encryption can secure data in case of a data breach in the enterprise. However, "the bad news is that traditional encryption techniques can also pose limitations to the functionality of cloud applications," says the alumnus. "I call this the 'square pegs-round-holes' problem." This is because every type of sensitive data comes with its own format. "Not only do credit card numbers have to be 16-digit strings, but salaries must be positive integer numbers, emails must be alphanumeric strings with an ‘@’ character, a domain name, and a TLD like ‘.com’, and so much more," Ristenpart writes in the article. "So it’s not just that square pegs must fit into round holes, but also stars, triangles, pentagons, rhombuses, and so on." While he is not the first expert to talk about format-preserving encryption (FPE), the CSE alumnus and colleagues have come up with encrption algorithms that are not only secure, but also solve the key usability issues of making it easy to specify a peg size. "Creating a new encryption engine is something that any developer can do seamlessly," explains Ristenpart. "This allows them to quickly adapt to the particulars of different cloud services... It's gratifying to see emerging security technologies bring these types of academic breakthroughs to the cloud security market," Ristenpart added. "The intention is that with more functional encryption capabilities, companies will be able to enable cloud services for a wider range of use cases."

  • Deadline to Submit IDI Proposals for Funding in 2015-16

    Vice Chancellor for Research Sandra Brown and CSE Prof. Larry Smarr in his capacity as director of UC San Diego's Integrated Digital Infrastructure (IDI) initiative have set a deadline of June 15 for faculty seeking support of two kinds: funding for transformational projects, and funding for digital research platforms.

    The projects getting the green light will start receiving support in September. The one-year projects will fund work with campus IT providers (including ACMS, ACT, Qualcomm Institute, The Library and SDSC) that is consistent with the university's strategic plan. Specifically, IDI is supposed to develop and promote "the use of novel digital, computing and/or networking technologies." Faculty are considered early adopters of technologies that will allow them to explore the application of new digital methodologies in research and education.

    The 'transformational' grants will range from $1,000 to $75,000, to enhance research in a single lab or teaching a specific class or set of classes. The Digital Research Platform grants range from $50,000 to $300,000 and must serve the needs of multiple faculty members, research staff and students. The larger grants are intended to create distributed but unified environments for advanced research in order to make UCSD researchers more competitive for external funding from NSF, NIH and other agencies.

    Who is eligible to submit a proposal? Any academic who is eligible to serve as a Principal Investigator on an extramural award may request a grant. However, only personnel with instructional responsibilities are eligible to submit a request for an instruction-related project.
