OEN Webinar: How to talk to investors, with Dave Yewman
Roll back

WHAT'S THIS ABOUT?
Picture this: standing up on stage: you, next to a projector screen filled with your slides.
Sitting in the audience: a room full potential investors and influencers who can either help you or dismiss you.
It's showtime. What, exactly, do you say? How, precisely, do you talk to an investor? And can you avoid the oh-so-common mistakes made by dozens of entrepreneurs who've pitched and failed?
If you're someone who's ready to ask for money - or even just someone who wants to get better at presenting - you don't even need to leave your desk. Just grab a cup of coffee and click on the URL that will be sent to you via email after you register for OEN's Webinar: How to talk to investors. Think of it as getting some practical presentation tips while wearing your bunny slippers.
You'll be able to watch presentation coach Dave Yewman demonstrate how to effectively communicate your message, how to get right to the point, and how to avoid common mistakes. You'll also be able to submit questions online.

IEEE OREGON Virtual Worlds Symposium
Roll back
| description |
Co-sponsored by: National Center for Rehabilitative Auditory Research, NCRAR
Goto: http://ewh.ieee.org/mu/oregon-ims-css/ for detailed symposium info.
In the context of this symposium, a virtual world will be defined as a computer-based simulated 3D virtual environment in which users, taking the form of avatars visible to others graphically, inhabit, create and use objects, and interact with each other. Although, the usage of virtual worlds for entertainment purposes might be generally understood, the increased usage of virtual worlds for education, business, professional and commercial applications is not yet well understood.
The purpose of this symposium is introduce 1) present tutorials and examples of usage of a selected virtual social environment, Second Life®, which is being used by the IEEE® professional organization to educate, communicate, and promote membership collaboration, present examples of Second Life being used in a wider range of engineering fields such as architecture, mechanical design, corporate group meetings, 2) present a keynote address by an IEEE Instrumentation & Measurement Society Distinguished Lecturer on research topics in the area of virtual social environments and multi-player gaming, and, 3) host a âgeekfestâ event with presentations demonstrating wide-ranging universe of virtual worlds, applications, tools, and situations.
It is anticipated the symposium will be jamb-packed with entertaining multimedia presentations, fun for attendees and fun for presenters. The symposium will be considered a success if those attending leave with greater knowledge, deeper understanding, and lots of thoughts on how virtual world technology is, could, or might be applied in our world. Finally, it is hoped the symposium will help foster continued cross-generation, cross-discipline fellowship and learning on this topic.
Speaker(s): Dr. Shervin Shirmohammadi,

Be a Beacon of Goodness: How Nonprofits Can Leverage Location-based Services
This month we dive into the growing location-based marketing trend with geo-location tools of Foursquare, Gowalla, Whrrl, Facebook Places, and SCVNGR, and discover how they can be used to spread awareness, fundraise, build community, and engage action.
Explore how Whrrl’s Societies are used to build communities and bring like-minded people together. Use Foursquare’s “Tips” to increase consciousness and fundraise for your cause or organization. Employ supporters into action by creating SCVNGR challenges. Play a game of tag with Facebook Places to spread your message amongst the 600 million plus Facebook users.
Come on in and join the conversation! We'd love to have you. |

Galois Tech Talk: Faster Persistent Data Structures Through Hashing
Roll back
| description |
nil |
→ |
Presented by Johan Tibell.
The most commonly used map (dictionary) data type in Haskell is implemented using a size balanced tree. While size balanced trees provide good asymptotic performance, their real world performance is not stellar, especially when used with keys which are expensive to compare, such as strings.
In this talk we will look at two different map implementations that use hashing to achieve better real world performance. The implementations have different performance characteristics: one provides very fast look-ups while the other trades better insert performance for somewhat slower look-ups. I will describe the design of these data structures and show some early benchmark results. |

<a href="http://idealist.org">Idealist.org</a> recently rolled out a new support which included a completely re-architectured backend. 3 developers from Idealist.org will be presenting on different components of infrastructure:
<strong>Long Talks:</strong> (~30min)
* Michel Pellitier on Using Xapain for Full-Text Search
* Jason Kirtland on Using RabbitMQ for Pub/Sub
<strong>Short Talk:</strong> (~15 min)
* Dan Colish on Redis - "If you're not using Redis, you suck"

Galois Tech talk: The Strategy Challenge in Computer Algebra
Roll back
| description |
Presented by Grant Passmore.
In automated deduction, strategy is a vital ingredient in effective proof search. Strategy comes in many forms, but the key is this: user-specifiable adaptations of general reasoning mechanisms reduce the search space by tailoring its exploration to a particular class of problems. In fully automatic theorem provers, this may happen through formula weights, term orders and quantifier triggers. In interactive proof assistants, one may build strategies by programming tactics and carefully crafting systems of rewrite rules. Given that automated deduction often takes place over undecidable theories, the recognition of a need for strategy is natural and happened early in the field. In computer algebra, the situation is rather different.
In computer algebra, the theories one works over are often decidable but inherently infeasible. For instance, the theory of real closed fields (i.e., nonlinear real arithmetic) is decidable, but any full quantifier elimination algorithm for it is guaranteed to have worst-case doubly exponential time complexity. The situation is similar with algebraically closed fields (e.g., through Groebner bases), and many others. Usually, decision procedures arising from computer algebra admit little means for a user to control them. But, when it comes to practical applications, is an infeasible theory really so different from an undecidable one?
The Strategy Challenge in Computer Algebra is this: To build theoretical and practical tools allowing users to exert strategic control over the execution of core computer algebra algorithms. In this way, such algorithms may be tailored to specific problem domains. For formal verification efforts, the focus of this challenge upon decision procedures is especially relevant. In this talk, we will motivate this challenge and present two examples from our dissertation: (i) the theory of Abstract Groebner Bases and its use in developing new Groebner basis algorithms tailored to the needs of SMT solvers (joint with Leo de Moura), and (ii) the theory of Abstract Cylindrical Algebraic Decomposition and a family of real quantifier elimination algorithms tailored to the structure of nonlinear real arithmetic problems arising in specific formal verification tool-chains. The former forms the foundation of nonlinear arithmetic in the SMT solver Z3, and the latter forms the basis of our tool RAHD (Real Algebra in High Dimensions). |
