How do I call one constructor from another in Java?
...
I would agree that a very complex transformation likely indicates a design issue. But 1) there are some simple transformations which for which this may be useful - not all constructors are just linear projection on others and 2) there may be other situation w...
ggplot with 2 y axes on each side and different scales
...lot2 because I believe plots with separate y scales (not y-scales that are transformations of each other) are fundamentally flawed. Some problems:
The are not invertible: given a point on the plot space, you can not uniquely map it back to a point in the data space.
They are relatively hard to re...

Task not serializable: java.io.NotSerializableException when calling function outside closure only o
...a local one.
Not to get into too many details, but when you run different transformations on a RDD (map, flatMap, filter and others), your transformation code (closure) is:
serialized on the driver node,
shipped to the appropriate nodes in the cluster,
deserialized,
and finally executed on the no...
What is the use of Enumerable.Zip extension method in Linq?
... by one, into a single new sequence. So you take an element of sequence A, transform it with the corresponding element from sequence B, and the result forms an element of sequence C.
One way to think about it is that it's similar to Select, except instead of transforming items from a single collect...
Can someone explain the traverse function in Haskell?
...
Let's use Maybe as Applicative and list as Traversable. First we need the transformation function:
half x = if even x then Just (x `div` 2) else Nothing
So if a number is even, we get half of it (inside a Just), else we get Nothing. If everything goes "well", it looks like this:
traverse half [...
What is referential transparency?
...apital since 1999 and that capital is Edinburgh.
This sentence cannot be transformed to a nutty one. Problem solved! The point of Quine was to say that natural language is messy, or at least complicated, because it is made to be convenient for practical use, but philosophers and logicians should...

Using a strategy pattern and a command pattern
...not the best, but good example of strategy is one connected with javax.xml.transform.Source interface: depending on whether the passed object is DOMSource or SAXSource or StreamSource the strategy (= XSLT transformer in this case) will apply different rules to process it. The implementation can be a...
