Last Wednesday (3/15), the 7th meetup was held in Silicon Valley. This meetup was special because we invited friends from the NoSQL community. This was the first co-sponsored event between Silicon Valley NoSQL Meetup Group and Graph Database in Silicon Valley. The number of attendees set a record: 41. We had to prepare everything more than twice than usual.
Our guest speaker was Dr. Julian E. Gomez with Polished Pixels. Dr. Julian Gómez has spent the last few decades pushing 3D computer graphics into new areas. His career has been equally split between academia and industry, including the publication of a number of papers, software products, and websites, with a focus on interdisciplinary R&D. Julian started his career at the NASA Jet Propulsion Laboratory Computer Graphics Laboratory, and has also been at RIACS in the NASA Ames Research Center, Macromedia, Apple Computer, LEGO and Sun Microsystems, and he is co-founder of several startups.
His presentation was on the Voyager encounter with Jupiter.
Here’s a brief excerpt from his presentation:
Each Voyager spacecraft comprises 65,000 individual parts. Many of these parts have a large number of “equivalent” smaller parts such as transistors. One computer memory alone contains over one million equivalent electronic parts, with each spacecraft containing some five million equivalent parts. Since a color TV set contains about 2500 equivalent parts, each Voyager has the equivalent electronic circuit complexity of some 2000 color TV sets. To figure it out, they started to use database.
Like the HAL computer aboard the ship Discovery from the famous science fiction story 2001: A Space Odyssey, each Voyager is equipped with computer programming for autonomous fault protection. The Voyager system is one of the most sophisticated ever designed for a deep-space probe. There are seven top-level fault protection routines, each capable of covering a multitude of possible failures. The spacecraft can place itself in a safe state in a matter of only seconds or minutes, an ability that is critical for its survival when round-trip communication times for Earth stretch to several hours as the spacecraft journeys to the remote outer solar system.
Both Voyagers were specifically designed and protected to withstand the large radiation dosage during the Jupiter swing-by. This was accomplished by selecting radiation-hardened parts and by shielding very sensitive parts. An unprotected human passenger riding aboard Voyager 1 during its Jupiter encounter would have received a radiation dose equal to one thousand times the lethal level.
After the session, many questions were asked from the audience. The Q&A session lasted well into the evening.
The 8th meetup will be held on 4/19 in Silicon Valley. The guest speaker will be Dehowe Feng, Junior Software Developer with Bitnine. He will present movie data analysis using AgensGraph.
Thank you for everyone for your meetup support.
