In the post “Why learning to code makes my brain hurt”, Mamie Rheingold explains why it is essential for all of us to learn to code. I agree. However, it always makes my brain hurt too.
How a 1930's theory explains the economics of the internet: Ronald Coase discovered “transaction costs” in the 1930s and it looks like his insight explains the extraordinary success of firms that take advantage of the Internet in their business model.

Listen to this podcast on the importance of metadata in big data. We need to be able to use metadata to find the valuable pieces of data within large datasets. Users need to be confident of the data and the context that metadata adds provides users to understand the information. Interpretation of big data requires an explicit understanding of metadata.

I am rereading Ambient Findability by Peter Morville for a course that I am facilitating at the Information and Knowledge Strategy Program at Columbia University. I search around for addtional material on the book and Peter Morville and found this video of his talk to Google Tech Talks. This is a great presentation and adds deeper insight into Peter's findability comments and the book.
This video provides an excellent and simple introduction to the Semantic Web and at the end provides links to additional sites for more information. Since I am working in text analysis and exploring how to add metadata, taxonomy, and more descriptive data to content this is very helpful. Manu Sporny is the co-chair of the RDFa working group at the World Wide Web Consortium. Interestingly, �RDFa helps bloggers and website authors make their web pages smarter by adding machine-readable information to a site. RDFa gives hints to web browsers, which give people more options when interacting with a web page. RDFa enables new interactions such as automatically adding people to address books, adding events to personal calendars, getting directions to a place described by RDFa, or searching online bookstores for a book marked up using RDFa.��
I finally figured out how to make this little application work and it is really cool. Once you install the Synergy+ app on your main computer and install the same app on your other computers, you can share one mouse and keyboard between multiple machines!
Interesting features include:
- Move your mouse easily between computers
- Requires nothing other than existing ethernet
- Copy and paste between your computers
- No need to press any buttons (unlike KVM)
- You can still use multiple monitors on the same computer
- Lock the mouse to one screen temporarily (useful for games)
