Von Liebig Center in New York Times
The Von Liebig Center here at the Jacobs School is highlighted in a great story in the New York Times with the headline "The Idea Incubator Goes to Campus" by Bob Tedeschi.
The story is about how universities are supporting the commercialization of the early-state inventions that stream out of universities every year.
From the New York Times story:
The story mentions by name Mushroom Networks and Biological Dynamics -- two of the 26 companies that the von Liebig Center has helped through seed funding, advisory services and entrepreneurship classes. Those startups have created more than 180 jobs and attracted more than $87 million in financing.
Mushroom Networks is a UC San Diego startup founded by electrical engineering professor Rene Cruz in 2004. Mushroom Networks provides innovative networking solutions. On their Web site Mushroom Networks writes, "Our products and services are focused on a range of networking solutions for Internet access for the broadband industry and networking solutions for the digital living room."
Biological Dynamics was founded in 2009 by then UC San Diego bioengineering Ph.D. student (now alumnus) Raj Krishnan. Biological Dynamics is developing early-stage cancer diagnostics that identify and separate secondary cancer biomarkers directly from blood, such as cell-free circulating high molecular weight DNA.
The story is about how universities are supporting the commercialization of the early-state inventions that stream out of universities every year.
From the New York Times story:
In the jargon of academia, the locations of such matchmaking are known as “proof-of-concept centers,” and they’re among a number of new approaches to commercializing university research in more efficient and purposeful ways — and to preventing good ideas from dying quietly. The first proof-of-concept center, the William J. von Liebig Center, was established in 2001 at the University of California, San Diego.

Gizmag Glances at SleepServer
Gizmag has a SleepServer story up on their super-high-traffic tech blog today.
Check it out...and the easy-to-read summary from the Jacobs School of Engineering is here, and a longer, more technical summary is here.
Pictures!
Xconomy Highlights Electrical Engineering Startup: Mushroom Networks
Mushroom Networks, the startup founded by electrical and computer engineering (ECE) professor Rene Cruz is profiled today in a story by Bruce Bigelow on the business/technology Web site Xconomy.
Read the story "Mushroom Networks Uses “Bonding” Technology to Pump More Data Through Bottlenecks"
from the Xconomy story:
Read the story "Mushroom Networks Uses “Bonding” Technology to Pump More Data Through Bottlenecks"
from the Xconomy story:
"The technology was developed by Rene Cruz, a Mushroom Networks co-founder and professor of electrical and computer engineering at UC San Diego. Cruz is known for his pioneering research in a field called network calculus, which is used to characterize the flow of data through the Internet and other packet-switching networks."
The San Diego Union Tribune ran the story too.

Stout: An Adaptive Interface to Scalable Cloud Storage
I just noticed that SleepServer is not the only UC San Diego computer science paper being presented this week at the 2010 USENIX Annual Technical Conference in Boston.
"Stout: An Adaptive Interface to Scalable Cloud Storage," John C. McCullough, University of California, San Diego; John Dunagan and Alec Wolman, Microsoft Research, Redmond; Alex C. Snoeren, University of California, San Diego.
The abstract is below:
Many of today's applications are delivered as scalable, multi-tier services deployed in large data centers. These services frequently leverage shared, scale-out, key-value storage layers that can deliver low latency under light workloads, but may exhibit significant queuing delay and even dropped requests under high load. Stout is a system that helps these applications adapt to variation in storage-layer performance by treating scalable key-value storage as a shared resource requiring congestion control. Under light workloads, applications using Stout send requests to the store immediately, minimizing delay. Under heavy workloads, Stout automatically batches the application's requests together before sending them to the store, resulting in higher throughput and preventing queuing delay. We show experimentally that Stout's adaptation algorithm converges to an appropriate batch size for workloads that require the batch size to vary by over two orders of magnitude. Compared to a non-adaptive strategy optimized for throughput, Stout delivers over 34x lower latency under light workloads; compared to a non-adaptive strategy optimized for latency, Stout can scale to over 3x as many requests.

PCs Sleep (and Work) Through the Night with SleepServer
Leaving your computer on all night/weekend/break just in case you need to connect remotely…that’s SO last decade. UC San Diego computer scientists created software that lets you put your computer to sleep without worrying that you’ll have to schlep your way to campus on Saturday night just because you suddenly need to access your computer connected to an enterprise network. SleepServer wakes up your sleeping PC remotely when you need it…but it won’t wake up the PC if the PC’s alter ego – a lightweight virtual image – can handle the job.
That’s the simplest example of how SleepServer helps UC San Diego cut its carbon footprint. But SleepServer does much more. That sleeping computer of yours also remains active on voice over IP/IM/peer-to-peer networks as well thanks to SleepServer.
How is this possible? When you put your computer to sleep, the software activates a lightweight virtual image of your PC which runs on a commodity server, along with hundreds of images of other PCs on your network. That virtual image can do a number of basic things that would otherwise require the actual PC to be awake.

SleepServer reduces energy consumption on enterprise PCs previously running 24/7 by an average of 60 percent, according to a new study presented today at the 2010 USENIX Annual Technical Conference.
Yuvraj Agarwal from UC San Diego is presenting this work TOMORROW June 25 in Boston at the 2010 USENIX Annual Technical Conference.
