db.people.createIndex({name: 1})
This creates an ascending single field index on the field name.
In this type of indexes the sort order is irrelevant, because mongo can traverse the index in both directions.

The tf.py_func() operator enables you to run arbitrary Python code in the middle of a TensorFlow graph. It is particularly convenient for wrapping custom NumPy operators for which no equivalent TensorFlow operator (yet) exists. Adding tf.py_func() is an alternative to using sess.run() calls inside t...
Some LINQ methods return a query object. This object does not hold the results of the query; instead, it has all the information needed to generate those results:
var list = new List<int>() {1, 2, 3, 4, 5};
var query = list.Select(x => {
Console.Write($"{x} ");

This is a copy of the advanced function snippet from the Powershell ISE. Basically this is a template for many of the things you can use with advanced functions in Powershell. Key points to note:
