update Calagator::Event 1250460654 (Friday) Tech talk: Building an Open-Source Autonomous Quad-Copter Roll back

description Presented by Nicholas Begley, Dave Dung Anh, James Heilinger, Alec Rasmussen, and Mark Theuson. It's a bird! It's a plane! No, it's an open-source autonomous quad-copter. In collaboration with the Portland State University Electrical and Computer Engineering Dept., Galois mentored a Spring semester Senior Capstone Project to build an ArduCopter. The ArduCopter is based on the Arduino open-source hardware platform, and includes infrared sensors (collision avoidance), sonar and barometer (altitude hold), GPS (location), magnetometer (direction), and gyro (stabilization). This talk will include a description of the ArduCopter and it's operation, including the trials and tribulations of building and testing one. Of course, the talk will include cool videos. → Presented by Nicholas Begley, Dave Dung Anh, James Heilinger, Alec Rasmussen, and Mark Theuson. It's a bird! It's a plane!

create Calagator::Event 1250460652 Pitch Club Roll back

description nil → Want to practice your startup pitch in front of people who've done it before? Crave the harsh criticism of your peers? Need the validation of seeing what works and what doesn't in other pitches? Bring your 3 minute pitch. Put your name in a hat and if it gets picked, you're on. Powerpoints discouraged - just pitch. Then, answer questions and listen to painfully honest feedback from a panel of so-called experts. The first rule of Pitch Club is you HAVE TO PITCH. The second rule of Pitch Club is you HAVE TO PITCH. It doesn't have to be your startup - pitch your blog, your ideas for turning cat feces into gold, or your plan for world domination. More rules as we think of them. FAQ: Q: Who are these so-called experts and what are they going to do to me? A: Your pitch will be evaluated by tech entrepreneurs and people who pitch for a living. They are your superiors. Q: What about NDAs? Someone's going to steal my idea! A: There are no NDAs - use your best judgment about what to talk about and what not to. Also, remember the first rule of fight club - don't talk about fight club. We're all on the honor system here. Q: My pitch is more than 3 minutes - can I have more time? A: No. Q: Will it be catered? A: Hell no. You know what's in the lobster bisque. Q: Can anyone critique a pitch? A: No, only the panel.

update Calagator::Event 1250460648 Pubtalk - Double Pitch & Hot Mic Night - June 22nd Roll back

description <b>Clark County Pubtalk Double-Pitch & Hot Mic Night - June 22, 2011 </b> Join us for June’s exciting high-energy Pubtalk event to hear two new hi-tech companies make their pitch and get a chance to speak in our new ‘hot mic’ session! A simple draw will determine which 5 people will have 90 seconds to make their pitch on the night! For the main double-pitch session we have two new companies offering hi-tech solutions for the 3D scanning sector and for the geo-thermal industry. <b>GLOBAL INSPECTION SOLUTIONS (GIS)</b> founded in 2009 by three engineers, believe there had to be an easier way to get real parts into digital 3D. They established a process that offers exceptional 3D scanning and they also have the ability to use 3D comparisons to quickly identify manufacturing defects that help determine not only what is wrong with a part, but why. Also presenting in June is <b>HELIDYNE</b> founded in 2008 to develop an innovative geothermal prime mover. The goal was to replace a turbine typically used in small (< 5 MW) modular units with an efficient, robust, and cost effective total-flow expander. Helidyne technology offers the ability to process brine directly as it emerges from the geothermal well. Find out more below and register soon as availability is limited! The event will take place from 5:00 p.m. – 8:00 p.m. at AHA!, 415 West Sixth Street, Suite 605, Vancouver, WA 98660. Our thanks also to AHA! for again generously donating their superb office space for the event. <b>REGISTER NOW - https://www.123signup.com/event?id=vrbsh</b> <b>Generously supported by our sponsors.

description nil → This meeting will be split into two parts: Justin Miller and Scott Neal will be presenting on Core Data. This is the second of two presentations on this vast topic. The second part of the meeting will be the fifth month of the Learning iPhone project (http://groups.google.com/group/pdx-cocoaheads-talk/browse_thread/thread/b6f453fca8284f1). Those who aren't interested in the class can head out for beer, and the rest of us will join them when we're done.

update Calagator::Event 1250460642 PSU CS Colloquium: Scrap Your Zippers: A Generic Zipper for Heterogeneous Types Roll back

description Scrap Your Zippers: A Generic Zipper for Heterogeneous Types Michael Adams, Indiana University <h5>Abstract</h5> The zipper type provides the ability to efficiently edit tree-shaped data in a purely functional setting by providing constant time edits at a focal point in an immutable structure. It is used in a number of applications and is widely applicable for manipulating tree-shaped data structures. The traditional zipper suffers from two major limitations, however. First, it operates only on homogeneous types. That is to say, every node the zipper visits must have the same type. In practice, many tree-shaped types do not satisfy this condition, and thus cannot be handled by the traditional zipper. Second, the traditional zipper involves a significant amount of boilerplate code. A custom implementation must be written for each type the zipper traverses. This is error prone and must be updated whenever the type being traversed changes. The generic zipper presented in this talk overcomes these limitations. It operates over any type and requires no boilerplate code to be written by the user. The only restriction is that the types traversed must be instances of the Data class from the Scrap your Boilerplate framework. <h5>Biography</h5> Michael D. Adams will be completing his Ph.D. in Computer Science at Indiana University this summer. He has a B.S. in Computer Science, a B.S in Computer Engineering and a Minor in Mathematics from the University of Kansas. His research interests are the implementation and construction of programming languages, compilers and software analysis tools that help programmers more easily implement, reason about, prove correct and improve the performance of their programs. This includes areas such as type systems, static analysis, control-flow analysis, compilers and optimization. In spring 2007, he worked on the X10 language for an internship at IBM Research. In summer 2007, he worked on the Glasgow Haskell Compiler at Microsoft Research. In 2008-2010 he worked for Cadence Research on the Chez Scheme compiler. He is an avid swing dancer and cyclist. → Scrap Your Zippers: A Generic Zipper for Heterogeneous Types Michael Adams, Indiana University <h5>Abstract</h5> The zipper type provides the ability to efficiently edit tree-shaped data in a purely functional setting by providing constant time edits at a focal point in an immutable structure.

create Calagator::Event 1250460644 52 Mobile Apps Rodamap Brainstorm Roll back

description nil → The initial reaction to 52 Mobile Apps has been really good, so we're going to start mapping out our next steps. Meet us at PIE to help figure out what it'll take to get things started. We'll go over what's been discussed so far, and start to plan the roadmap for what should be tackled next, and start drumming up excitement for the project. Categories we should hit first: * The website. It's ready, sort of. * Tutorials. First one should go live July 4th, so we have some time, but not tons. * The criteria for distributing and submitting app ideas, and the committee that will be voting on them. See you there!
