Usage to list all folders and files in the current directory: dir A target directory can also be specified: dir C:\TargetPath When specifying a path with spaces, it must be surrounded by quotes: dir "C:\Path With Spaces"

To store a graph, two methods are common: Adjacency Matrix Adjacency List An adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. Adjacent means 'next to or adjoining something el...

After you've enabled migrations (please refer to this example) you are now able to create your first migration containing an initial creation of all database tables, indexes and connections. A migration can be created by using the command Add-Migration <migration-name> This command will c...

Note that the allowDiskUse: true option is optional but will help mitigate out of memory issues as this aggregation can be a memory intensive operation if your collection size is large - so i recommend to always use it. var duplicates = []; db.transactions.aggregate([ { $group: { _id: { c...

There are several ways to implement a plugin system for a Java application. One of the simplest is to use URLClassLoader. The following example will involve a bit of JavaFX code. Suppose we have a module of a main application. This module is supposed to load plugins in form of Jars from 'plugins' f...

When some programmers see this advice: "Testing strings using == is incorrect (unless the strings are interned)" their initial reaction is to intern strings so that they can use ==. (After all == is faster than calling String.equals(...), isn't it.) This is the wrong approach, from...

Adjacency list is a collection of unordered lists used to represent a finite graph. Each list describes the set of neighbors of a vertex in a graph. It takes less memory to store graphs. Let's see a graph, and its adjacency matrix: Now we create a list using these values. This is called adjacen...

The STDIN stream in Julia refers to standard input. This can represent either user input, for interactive command-line programs, or input from a file or pipeline that has been redirected into the program. The readline function, when not provided any arguments, will read data from STDIN until a newl...

Reading numbers from standard input is a combination of reading strings and parsing such strings as numbers. The parse function is used to parse a string into the desired number type: julia> parse(Int, "17") 17 julia> parse(Float32, "-3e6") -3.0f6 The format expec...

Reading strings or bytes Files can be opened for reading using the open function, which is often used together with do block syntax: open("myfile") do f for (i, line) in enumerate(eachline(f)) print("Line $i: $line") end end Suppose myfile exists and its ...

Sometimes we need to collect data from google spreadsheets. We can use gspread and oauth2client libraries to collect data from google spreadsheets. Here is a example to collect data: Code: from __future__ import print_function import gspread from oauth2client.client import SignedJwtAssertionCred...

Apart from CSS, model, and binding selectors, protractor can also locate elements using xpath View <ul> <li><a href='http://www.google.com'>Go to google</a></li> </ul> Code var googleLink= element(by.xpath('//ul/li/a')); expect(element.getText()).to.event...

Templates require compile-time generation of code: a templated function, for example, will be effectively turned into multiple distinct functions once a templated function is parameterized by use in source code. This means that template function, member function, and class definitions cannot be del...
