how open source projects survive poisonous people (and...
54:58
Google Tech Talks January 25, 2007 ABSTRACT Every open source project runs into people who are selfish, uncooperative, and disrespectful. These people can silently poison the atmosphere of a happy developer community. Come learn how to identify these people and peacefully de-fuse them before they derail your project. Told through a series of (often amusing) real-life anecdotes and experiences. Credits: Speaker:Ben Collins-Sussman, Speaker:Brian Fitzpatrick

cgal: open source computational geometry algorithms library
54:59
Google Tech Talks March, 3 2008 ABSTRACT Introduction Project mission statement, history, internal organization, partners, CGAL in numbers. What's in CGAL A survey on available data structures and algorithms, as well as examples how and by whom they are used. Topics include Triangulations, Voronoi diagrams, Boolean operations on polygons and polyhedra, arrangements of curves and their applications, Mesh generation, Geometry processing, Alpha shapes, Convex hull algorithms, Operations on polygons, Search structures, Interpolation, Shape analysis, fitting, and distances, Kinetic data structures... Generic Programming Paradigm CGAL data structures are C++ template classes and functions, usually taking several template parameters (with default values for ease of use). This gives developers an incredible flexibility to adapt the data structures to their needs, which is important internally for code reuse, and important for end users, as they typically integrate CGAL in already existing applications. Parts of CGAL are also interfaced with languages and software like Python, Java, Scilab, Qt and the Ipe drawing editor. Exact Geometric Computing Paradigm We present how to make geometric algorithms correct, robust, and nevertheless fast, by combining floating point arithmetic with exact arithmetic, and clever filtering mechanisms to switch between these two modes. These mechanisms can be used for geometric predicates, as well as for geometric constructions, which instead of a discrete return value generate new geometric entities. Conclusion and Outlook A wrapup, and a sneak preview on algorithms that might make it into future releases of CGAL. Speaker: Andreas Fabri, PhD, GeometryFactory As member of the initial development team of the CGAL project, Andreas is one of the architects of the CGAL software. For several years he chaired the CGAL Editorial Board. In 2003, Andreas founded the GeometryFactory as spin-off of the CGAL project, offering licenses, service and support to commercial users. Andreas received his PhD in 1994 from the Ecole des Mines de Paris, while working on geometric algorithms for parallel machines at INRIA. Speaker: Sylvain Pion, PhD, INRIA Sophia-Antipolis Sylvain got involved in the CGAL project during his PhD, which he received in 1999 at INRIA. He worked then on providing generic solutions to numerical robustness issues arising in geometric algorithms. Later on he worked on the efficiency of some fundamental geometric algorithms such as 3D Delaunay triangulations. He is now also involved in C++ standardization, and is working on parallel geometric algorithms. He is employed as researcher at INRIA, and is the current chair of the CGAL Editorial Board.

multi-touch screens in open source world
72:42
Google Tech Talks June 9, 2008 ABSTRACT Multi-touch is a new way of human computer interaction, which recognizes multiple simultaneous touch points, as opposed to the standard touchscreen, which recognizes only one touch point at a time. There are many forms of natural input in order to simplify the way people interact with their PC's and devices, however with the introduction of Apple iPhone/iPod Touch, Microsoft Surface and other devices, multi-touch is becoming more and more popular. In this tech talk I will describe what is the history behind multi-touch screens, what kind of multi-touch devices are available and how do they work, focusing mostly on FTIR and DI technique. We will discuss how to receive multi-touch events in our applications using TUIO protocol and how to write multi-touch applications using just a simulator. We will look into available open source projects that can be used to operate multi-touch screens and that are being developed by Natural User Interface Group (NUI Group) community. Speaker: Pawel Solyga Pawel Solyga is a computer science student at Politechnika Wroclawska, Poland. He is a co-founder of Natural User Interface Group (NUI Group), whose main areas of interest are modern user interfaces and in particular mutli-touch sreens. Pawel is also a former Google Summer of Code student. For GSoC 2008, he's working as organization administrator and mentor for the NUI Group. When not contributing to Open Source projects, he's a software engineer at Natural User Interface Europe AB, working on innovative multitouch applications.

opportunities for open source biotechnology in underdeveloped countries
42:30
Google Tech Talks August 5, 2008 ABSTRACT Guido D. Nez-Mujica will be presenting on Science, Innovation and entrepreneurship in developing countries, specifically in Venezuela, where he is from. He decided to stay there, instead of going abroad, to do some cheap biotechnology that is useful to people, solves unmet needs and allows us to use our knowledge for more than academic purposes. The conditions there are very different from the conditions in developed countries. In terms of politics, as well as due to logistic and legal issues, some of those differences are drawbacks, while others can be treated as advantages. He believes that open source models could thrive in underdeveloped countries such as Venezuela and create successful examples of private initiative in places where the public sector runs almost everything. The presentation is less of a detailed analysis, and more of a personal perspective and account of the experiences in his lab with a current project: A kit for Chagas disease diagnostic, plus an overview of the general situation and the opportunities it offers. Speaker: Guido D. Núñez-Mujica

open source developers at google: amit singh on macfuse
84:13
File systems provide one of the most familiar interfaces end users know. Since implementing a traditional file system is extremely complex and difficult, presenting information seamlessly through files and folders has typically been limited to a small set of select programmers--often kernel hackers who develop at the lowest layers of a system. The MacFUSE mechanism breaks this barrier on Mac OS X by doing all the in-kernel hard work once and for all and leaving to the developer only the file-system-specific logic, which can be implemented as a regular user-space application. MacFUSE, with its simple programmer-visible API (same as the Linux FUSE API) and multiple language bindings, almost trivializes the process of making anything and everything appear seamlessly as a set of files and folders. You can use it to blur the line between the Macintosh Desktop and the Web. In this talk, you will hear the story of MacFUSE from its creator.

yochai benkler: open-source economics
17:53
http://www.ted.com Law professor Yochai Benkler explains how collaborative projects like Wikipedia and Linux represent the next stage of human organization. By disrupting traditional economic production, copyright law and established competition, they're paving the way for a new set of economic laws, where empowered individuals are put on a level playing field with industry giants.
