Write all events with level: debug, info, warn, error and fatal to one file: <?xml version="1.0" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <targets> &lt...

Create one log file for each day. The log files will have the following names (dependent of culture) 2016-06-05.log 2016-06-06.log 2016-06-07.log ... <?xml version="1.0" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://w...

To understand this example, it is recommended to have a brief idea about Bellman-Ford algorithm which can be found here Using Bellman-Ford algorithm, we can detect if there is a negative cycle in our graph. We know that, to find out the shortest path, we need to relax all the edges of the graph (V-...

declare is an internal command of bash. (internal command use help for displaying "manpage"). It is used to show and define variables or show function bodies. Syntax: declare [options] [name[=value]]... # options are used to define # an integer declare -i myInteger declare -i another...

use std::ops::Deref; use std::fmt::Debug; #[derive(Debug)] struct RichOption<T>(Option<T>); // wrapper struct impl<T> Deref for RichOption<T> { type Target = Option<T>; // Our wrapper struct will coerce into Option fn deref(&self) -> &Option...

Deref has a simple rule: if you have a type T and it implements Deref<Target=F>, then &T coerces to &F, compiler will repeat this as many times as needed to get F, for example: fn f(x: &str) -> &str { x } fn main() { // Compiler will coerce &&&&&&a...

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 ...

Java Logging Api has 7 levels. The levels in descending order are: SEVERE (highest value) WARNING INFO CONFIG FINE FINER FINEST (lowest value) The default level is INFO (but this depends on the system and used a virtual machine). Note: There are also levels OFF (can be used to turn log...

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...

XPath selectors can be used to select elements with specific attributes, such as class, id, title etc. By Class View: <div class="HakunaMatata"> Hakuna Matata </div> Code: var theLionKing= element(by.xpath('//div[@class="HakunaMatata"]')); expect(theLionKing.g...

lib.pagetitle = TEXT lib.pagetitle.data = page : title

$productCollection = Mage::getModel('catalog/product')->getCollection(); Selecting the specific Attribute $productCollection->addAttributeToSelect(array('name', 'product_url', 'small_image')); Selecting the All Attributes $productCollection->addAttributeToSelect('*'); Add Filter ...

The following example will contain a block of code that is meant to be split into several source files, as denoted by // filename comments. Source Files // my_function.h /* Note how this header contains only a declaration of a function. * Header functions usually do not define implementations...

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...
