This video covers a particular type of transistor known as the Bipolar Junction Transistors (BJTs). These are more commonly used in analog applications like amplification and signal processing rather than digital logic (though they can be used in specialized digital logic circuits).
Today, field effect transistors (FETs) reign supreme for most IC applications such as CPUs and digital logic as they're more scalable and efficient than BJTs and have a very different structural design.
It sounds like you're describing a Readme file -- which by convention can exist as documentation for any folder and not just the project root. It's not adopted by all codebases but is becoming more common as source browsers like Github will render the readme as rich text when navigating to the folder.
The short answer is no, the architectures don't transfer. At least not today. Biological neurons are much more complex, and therefore behave quite differently from neurons in neural networks.
To put things in perspective, we've fully mapped the connectome (map of neuron connections) of the simplest animal, C. Elegans, which has only about 300 neurons, yet we still can't simulate this organism's behavior computationally.
You can't give employees the power to filter content then label them as "rogue" when a bias inevitably emerges. Obviously any innate biases (overt or not) will influence what gets filtered.
If you're running an application that runs on more than one server it's definitely worth checking out AWS OpsWorks. It's a huge time saver and extremely useful in integrating and managing setup, configuration, and deployment across a server/db/cache etc without any loss of control or customization.
I've used Figaro for a few projects and I've found myself very happy with it. It does one thing well without adding unnecessary complexity or overhead to my app. I feel that figaro-like capability in Rails is a win for the community and for figaro/laserlemon as well.
Great stuff. The Rails Tutorial was my top resource when learning Rails and I still use it as a reference (along with RailsSpace and Railscasts). I'm using Rails 4 on a few projects, so if I can lend any feedback on the future release let me know.
Very true. It's also miserable with an IDE.
