Layered software architectures adhere to the Dependency Rule: Source code in a lower-level layer can make use of code in higher-level layers, but never vice versa. Control flow, however, goes in both directions. How is this possible, given that higher-level code must not know anything about the code in lower levels?
So you have built a robotic arm? Great, let’s write some Go to make it serve your five o’clock tea. Sounds simple enough. Or is it?
Artificial Neural Networks have gained attention during the recent years, driven by advances in deep learning. But what is an Artificial Neural Network and what is it made of?
Meet the perceptron.
This is the second (and, for the time being, the last) article about messaging and Mangos. After doing first steps with the Pair protocol, we now look into a slightly more complex protocol, the Publisher-Subscriber (or PubSub) protocol.
Consider two processes that need to exchange commands and data. You want to connect them in a way that is straightforward, efficient, and reliable. How would you do that?
