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.

| | CGAL: The Open Source Computational Geometry Algorithms Library - 3299 sec
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 the Open Source World - 4362 sec
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.

| | Open Source Developers at Google: Amit Singh on MacFuse - 5053 sec
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.

| | Interdisciplinary Studies of Open Source Software (OSS) Projects - 3185 sec
Google Tech Talks
February, 25 2008
ABSTRACT
We all love to hate large software systems. They are hard to build,
hard to evolve, and don't work very well. Why is this? A lot of reasons,
some social, some technical, and some socio-technical. We believe that OSS
provides an excellent source of data to test hypotheses about the factors
that affect important phenomena/outcomes in software projects. Our group
at UC Davis, comprising bio-informaticians, organizational behaviourists,
physicists, and software engineers, is using a range of different approaches
to the analyze the veritable torrents of data pouring out of open source projects
to understand how things work in OSS, and what tools and techniques can
help. One important issue is IMMIGRATION: how do new people
join projects, and how can we help the difficult intellectual and social
challenges they face. We present two results:
1.a) Can we build "recommender" tools that help programmers deal
with "information overload" by helping them focus their attention?
1.b) Such tools have always been evaluated with user studies. Can
we do something more quantitative?
2) What are the factors influencing immigration of new developers in Open source projects?
Joint work with: V. Filkov, A. Swaminathan, G. Hsu,
and students C. Bird, Z. Saul, and A. Gourley
We gratefully acknowledge support from NSF (Science of Design and
Human and Social Dynamics Programs), the IBM Faculty Fellowship Program,
and the GrammaTech and SciTools corporations.
Speaker: Prem Devanbu
Prem Devanbu is Professor of Computer Science at UC Davis,
he joined UC Davis after almost 20 years in Industry, including 17 years
at AT Bell Labs and its various offshoots. He received his
undergraduate degree in Electrical Engineering (Medium Current)
from IIT Chennai, India, and his M.S., and Ph.D from Rutgers University
in Piscataway, NJ.
