I have created a function that will remove outliers from a series of data. Generally the data n dimensional. Loosely, an outlier is considered an outlier if it +/- deviates by 1.5 standard_deviation's from the mean (see code for more detailed explanation of what constitutes an outlier).
The fun...

So this is my Todo script. It's working well apart from one irritation. For some reason my 'displayTodos' function (line 193) is doing it's job fine, but then reporting an error in the forEach loop AFTER it's finished - "TypeError: this.todos.forEach(...) is undefined".
Althought it doesn't appe...

The idea is to provide function composition (provided that the composed function types 'match'), with perfect forwarding of both callables and eventual function arguments:

}

Last year, we wrote about our important work to build a more welcoming and inclusive community. This summer, I wrote about how we are evolving our product to encourage better interactions and guidance. While there’s still a lot more to do, we’ve begun to take concrete steps toward a better coding community for everyone. This is the most important work we’re doing in our community, and our first wave of improvements are starting to show results.
Here’s one concrete example: For some time, we’ve been using machine learning to flag comments that might be potentially troublesome in the community, e …
You need a custom converter.
You are trying to convert a complex type, as a result Newtonsoft doesn't know what to do. The fix is rather trivial, and is documented here: Using a Custom JsonConverter to fix bad JSON results.
Because links go bad, what you need is the below:

Write a method to return a boolean if an input grid is magic square.
A magic square is a \$NxN\$ square grid (where N is the number of cells on each side) filled with distinct positive integers in the range \${1,2,...,n^{2}}\$ such that each cell contains a different integer and the s...
The Mongo-Scala Driver (v2.6) currently only supports asynchronous operations, although my use cases often seem to lend themselves well to synchronous reads. This may be to block downstream code execution, or to save off the result-set of documents for later use. I'm guessing there may be a way t...
