Corporate Finance

For anyone who is interseted in corporate finance Aswath Damodaran, from the NYU Stern School of Business, has a complete class on corporate finance from their MBA program online, including streaming video lectures. I am currently working through the lectures and working on doing the project. I am going to value Amicas, a company that makes PACS systems. I may post it here when I am done if it is interesting. Does anyone else have good resources for corporate finance?

GE Launches PeerVision

Today GE launched a beta release PeerVision which is a website that will help foster community collaboration on the web. The site has blogs, forums and a library. The site is organized around four communities, Outpatient Imaging Centers, Advanced Visualization, the Signa 3.0T (MRI Scanner), and MyReadingSpace. Within each of those communities there is a separate forum and blog. The blogging is done by guest bloggers who are not GE employees that will blog on important issues.

While I think that the site will be a net positive I think that it is somewhat limited. The primary two way communication medium will be the forums. I am not sure that the blogs will be updated enough, although I am an information junkie so I like lots of posts. I will be interested to see what the uptake among radiologists is. Radiologists tend to be older so the forums may work well. Auntminnie already has established forums and they do get traffic. I don’t consider PeerVision to be a game changer. I would have liked to see something with some social networking capabilities that might make it sticky among its users. The other thing that might have worked well is the Channel 9 model of building community around video or some other content. Let’s see what the people think….

O’Reilly on Multi-core

Tim O’Reilly posted pieces of a conversation about the wall that we have almost hit with processor speed. I just wanted to add that not only do most applications not take advantage of multi-core processors, the complexity of writing multi-threaded applications will mean that most applications will never see the advantages of multi-core processors. What is need are tools that enable the underlying operations to be parallelized without the programmer having to immerse himself in those details. There are already examples of this, web applications for instance. A webserver handles this problem beautifully. The programmer creates the site and it easily services multiple users and many can scale to the millions of users. Of course you get into other problems but that is not the point. Finally I want to point out that many problems will never be able to take advantage of multi-core processors since they are not operations that are easily broken into multiple paths of execution.

Bernie Huang

Dalai has a post about Dr. Bernie Huang. Dr. Huang truly is an expert and leader in the field of imaging informatics. I just wanted to add that he has written what I consider to be by far the best book on the topic, PACS and Imaging Informatics: Basic Principles and Applications. The book is a very in depth text book that explains the principles of many technologies that are used in imaging informatics.
