[ Economics ] Profit and Leverage

Jon Hilsenrath, Damian Paletta and Aaron Lucchetti, "Goldman, Morgan Scrap Wall Street Model: End of Traditional Investment Banking," The Wall Street Journal, Sept. 22, 2008:

The most fundamental problem is how to generate profit growth in a world that no longer tolerates high leverage.

[ Networks ] Social Networks and Security

Social networks pose interesting new problems for security experts. Erica Naone's article ("Turning Social Networks Against Users") explores some of these problems. Naone includes a brief discussion of some research involving a malicious third party application for Facebook.

The problem rests in open access to the computing platform of the social networking web sites. Furthermore, "social factors also play an important role...because social networks foster an atmosphere of trust that is easy to exploit."

Attacks could be more complex than those already used for secruity research focused on social networks. "An attacker could build a legitimate application, wait until a large number of users have installed it, then make the application 'go bad' by updating it with malicious code."

Perhaps, some social networking sites will make it a requirement that all third party applications implemented for their network be made available openly (open, buildable source).

[ Technology ] Future of Business Technology

Check out MIT Technology Review's special reports on "The Future of Business Technology".

You may want to read the story of Postful and Figaro Interactive, and the accompanying contrast between Amazon Web Services and Google App Engines.
