Scientist Uses Nanodots To Create 4Tb Storage Chip 207

arcticstoat writes "Solid state disks could soon catch up with mechanical hard drives in terms of cost and capacity, thanks to a new data-packed chip developed by a scientist at the University of North Carolina. Using a uniform array of 10nm nanodots, each of which represents a single bit, Dr. Jay Narayan created a data density of 1 terabit per square centimeter. The end result was a 4cm2 chip that holds 4Tb of data (512GB), but the university says that the nanodots could have a diameter of just 6nm, enabling an even greater data density. The university explains that the nanodots are 'made of single, defect-free crystals, creating magnetic sensors that are integrated directly into a silicon electronic chip.' Dr. Narayan says he expects the technology overtaking traditional solid state disk technology within the next five years."

Hello.

Seeing as rails was not released publicly till July 2004 this is does not surprise me.

Seriously though, 5 years is a very long time for an open source project which has grown to have over a thousand people contribute code to it.

Perhaps with the release of rails 3, with its particular emphasis on modularity and configurability, it would be a good time to re-evaluate?

Also, I read you post and found no know-it-all reference.

Not true.

Model.find_by_sql sqlstring

or even more primitively:
ActiveRecord::Base.connection.execute( sqlstring )

Easy. Although you really shouldn't have to use it if you understand relations properly.

Also note that rails 3 is going to have Arel, an Object-Oriented interpretation of the Relational Algebra. It is a mathematical model for representing “queries” on data. It understanding relations this fundamentally means it can optimise easily.

Have a look at:
