I'm not sure how much time the new grad students at Berkeley spend "talking shop" online -- I think right now they are focused on finishing their coursework and on their local research projects. We usually check out the LAPACK forum / e-mail list for linear algebra questions and the appropriate mailing lists for subject-specific questions. I've been on general forums before and they tend to be time sinks, because we get lots of "n00b" questions from people who may just be too lazy to look up the answers themselves. LinkedIn is good for job networking. So it's hard to work on starting up yet another community -- which is a good community, don't get me wrong! and indeed even a good idea to shape as a social networking thing rather than just a forum or e-mail list, because it gives you a sense of reputations. It's esp. hard since I'm writing my thesis and some papers now ;-)

I usually do well with complex challenging problems. Perhaps we should talk on the phone (203 727-0280if you'd like. Here's my Linked In profile:

First Iam extremely happy and thankful that people like you are promoting computational engineering. Iam doing my MS in that.I have always had a hard time in explaining to others what it actually means.
It is true that Iam working in CFD and interested in quant finance(informally). My idea has always been to understand the essence of developing computational math models to understand the behaviour of mother nature.let it for fluid dynamics,heat transfer or finance.

No luck, people here are somewhat lazy and sometimes they are not willing or cannot discuss things without signing NDAs (most of them work for the industry). The idea of creating a packaging group is, in my opinion, really cool. We have to give people some time, I think. Topics discused here are not easy and write an answer requires time and a deep understanding of the subject, so you cannot expect, IMHO, that people will use this as a social scientific network. In my experience, I have found that gathering people toward a common goal (realization of a software, benchmarking, wiki writing, etc.) can help. Personally I found ning layout quite confusing (I am writing on a notepad while looking at you comment) because the interface ning gives is oriented more toward social networking like chatting about parties and travels, than to organize people discussion on such complex topics. Anyway this is just a nuisance, not really an obstacle. My recipe is: time :)

At 2:33pm on June 3, 2008, Mubeen said…: Theodore,
I am going to finish the course work of MSc by this semester. I have a good understanding of almost all subjects (materials, mechanics and programming), but I have one problem. Even though I am above average student but I am feeling like a dummy at the moment. I am not sure about the chances I would have for a good thesis and/or PhD, perhaps because I don't have good contacts with any research group, or academic staff. I have applied for thesis and also for PhD, but didn't get any reply. May be due to the problem that I always love to work in isolation (and this is first time I am out on internet), will I be facing problems to proceed further??

Profile Information

What is your CSE experience?: Developer, professional, engineer

About Me:: I am the founder of Stillwater Supercomputing where we are building the next generation platform for computational science and engineering. At Stillwater we believe that the 21st century belongs to the computational scientist and that many important innovations will be driven by computational models. We want to aid in that quest.

What are your interests?: My main interest is in using computer models to gain an understanding of complex systems. After that, automating complex decision making on the basis of these models is the next step.

What are your skills?: parallel computing, hardware design, electronics, high performance computing

Which CSE subdiscipline(s) would you like to network within?: quantitative finance, digital content creation, and CAE

Open Source Conference

I just came across Matt Raible's report on the OSCON'08.

A couple of tidbits from that post:

IT jobs are 2.3% of all jobs posted, according to the Bureau of Labor Statistics. Technology oriented companies (e.g., Google, Yahoo, Sun) make heavy use of Open Source (40% of all jobs posted by Y!). Open source is growing faster in non-tech companies. Of the open source technologies in the enterprise, the highest share of jobs is… Continue

Laws of data driven decision making

I came across a wonderful, somewhat tongue in cheek, posting by Edmund Freeman here. Anyone that has been asked to do an analysis to support decision making will recognize these principles. Here they go:

Certainty Principle: Certainty is inversely proportional to knowledge
Anyone that works with data will understand the limitations of data and any inference analysis or signal processing. When maki… Continue

Computational Science and Engineering book

I was looking for a classification of algorithms used in Computational Science and Engineering for Stillwater's trifecta. In all classification problems, selecting the right attributes is key. I was on the wrong path since I was trying to use a classification based on solver algorithm structure and that caused significant problems since it appears to cause a decoupling of the physical intuition of the original problems. So I started to look for others who have attempted to construct a structure… Continue

Climate Prediction

While researching climate models I came across a BOINC based community for climate prediction: climateprediction.net at http://www.climateprediction.net

From their website:

The aim of climateprediction.net is to investigate the approximations that have to be made in state-of-the-art climate models. By running the model thousands of times (a 'large ensemble') we hope to find out how the model responds to slight tweaks to these approximations - slight enough to not make the approximations any le… Continue
