How efficient is Tarsnap's deduplication? It depends on what kind of data you are backing up, and how often. Let's look at a few examples, produced via the --print-stats option.

There's a number of factors motivating the change. We'll explore the reasons, from long term viability of Subversion, to wider support for tools that will make the project better. Today I'll enumerate these points. There are some logistical points around how the decision was made. I'll not get into the politics about how we got here, though. While interesting for insiders who like to argue and quibble, they are no more relevant to the larger community that the color of the delivery truck that delivered groceries to your grocer this morning (even if it had the latest episode of a cool, scrappy cartoon cat that was involved in a multi-year arc wooing the love of his life by buying food at this store).

In a neural network, numeric data points, called inputs, are fed into the neurons in the input layer. Each neuron has a weight, and multiplying the input number with the weight gives the output of the neuron, which is transferred to the next layer.

The activation function is a mathematical “gate” in between the input feeding the current neuron and its output going to the next layer. It can be as simple as a step function that turns the neuron output on and off, depending on a rule or threshold. Or it can be a transformation that maps the input signals into output signals that are needed for the neural network to function
