The nearest are probably Parson's parking structure and the adjacent lot on the corner of Union and Pasadena Ave. On-street parking is metered, but only until 8pm. That's the least expensive parking option, but availability is limited. For rail users, the nearest Goldline Metro stop is Memorial Park, which is a few blocks east of the Idealab offices and is a great option for those coming from LA.

May 21 Meeting: NASA, Big Data, and Apache OODT

Summary

The talk will cover the functionality and genesis of the Apache OODT technology, originating from NASA and now a top-level project alongside of Apache HTTPD, as well as covering Hadoop and other technologies at the Apache Software Foundation (ASF). OODT provides components for file and metadata management, workflow,  resource management, science algorithm integration, remote data acquisition and automatic file ingestion. Users can pick their components a la carte, or combine them in unique ways. Many of the core parts of OODT leverage Java technologies (Maven, Ant, Tika, etc.). He'll frame the discussion in terms of some modern Big Data challenges involving the US National Climate Assessment and the International Square Kilometre Array (SKA) project in radio astronomy, two diverse domains that OODT is helping to support.


Chris Mattmann has a wealth of experience in software design, and in the construction of large-scale data-intensive systems. His work has infected a broad set of communities, ranging from helping NASA unlock data from its next generation of earth science system satellites, to assisting graduate students at the University of Southern California (his Alma mater) in the study of software architecture, all the way to helping industry and open source as a member of the Apache Software Foundation. When he's not busy being busy, he's spending time with his lovely wife and son braving the mean streets of Southern California.

Gail Hernandez will describe the development of Liferay Sync, an open source package that provides file synchronization capabilities similar to Dropbox.com.

Rough Agenda:

7:00pm - 7:15pm Start to Eat & Mingle
7:15pm - 7:25pm Introductions
7:25pm - 7:30pm Identify those with open positions (please no announcements from contingency recruiters)
7:35pm - 7:37pm Speaker & Talk Introduction
7:37pm+ The Talk!

Liferay Sync works with the web based Liferay Document Library to provide desktop access to files stored in the Document Library.  The concept is simple enough.  Keep the files and folders that are in the web-based folder in sync with the files on the users’ local desktop.  Like many things, the devil is in the details.  Many design constraints further clouded the issue.  We wanted a lightweight application that could run on any OS, no heavy weight database and fast performance. Most of all we want no data loss. The solution was a Java engine, with a Java based UI, connected with C++ based shell extensions for complete integration into the environment. This presentation will discuss the hurdles faced, the design decisions and tradeoffs that had to be made, as well as plans and goals for the future.

Gail Hernandez is a Senior Software Engineer at Liferay, Inc. She joined the company in March 2011, after working in the defense industry for the past decade. There, she developed an eclectic collection of experience. She has worked on diverse projects including C3I systems for unmanned aircraft, Open Road Tolling systems, mobile command center systems for first responders, and GPS systems. Gail holds a B.S. in Computer Science from Cal Poly Pomona and a M.S. in Software Engineering from Cal State Fullerton.

Please RSVP on the new Meetup site so we can get a headcount for food and drink:

When: Monday, Oct 3, 2011 at 7pm
Location: 130 W Union St, Pasadena, CA 91103
Directions: http://www.idealab.com/contact_us/our_location.html

7:00pm - 7:15pm Start to Eat & Mingle

7:35pm - 7:37pm Speaker & Talk Introduction
7:37pm+ The Talk!

Here is a synopsis of the talk that George Chang will be giving:

The Lunar Mapping and Modeling Project (LMMP) is tasked to aggregate lunar data, from the Apollo era to the latest instruments on the LRO spacecraft, into a central repository accessible by scientists and the general public. A critical function of this task is to provide users with the best solution for browsing the vast amounts of imagery available. The image files LMMP manages range from a few gigabytes to hundreds of gigabytes in size with new data arriving every day. Despite this ever-increasing amount of data, LMMP must make the data readily available in a timely manner for users to view and analyze. This is accomplished by tiling large images into smaller images using Hadoop, a distributed computing software platform implementation of the MapReduce framework, running on a small cluster of machines locally. Additionally, the software is implemented to use Amazon's Elastic Compute Cloud (EC2) facility. We also developed a hybrid solution to serve images to users by leveraging cloud storage using Amazon's Simple Storage Service (S3) for public data while keeping private information on our own data servers. By using Cloud Computing, we improve upon our local solution by reducing the need to manage our own hardware and computing infrastructure, thereby reducing costs. Further, by using a hybrid of local and cloud storage, we are able to provide data to our users more efficiently and securely. This talk examines the use of a distributed approach with Hadoop to tile images, an approach that provides significant improvements in image processing time, from hours to minutes. This talk describes the constraints imposed on the solution and the resulting techniques developed for the hybrid solution of a customized Hadoop infrastructure over local and cloud resources in managing this ever-growing data set. It examines the performance trade-offs of using the more plentiful resources of the cloud, such as those provided by S3, against the bandwidth limitations such use encounters with remote resources. We will outline some of the technologies employed, the reasons for their selection, the resulting performance metrics and the direction the project is headed based upon the demonstrated capabilities thus far.
