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...

Blue/Green deployment is a release technique that reduces downtime and risk by running two identical production environments (one called "Blue", the other called "Green"). At any one time, only one of the environments is serving live traffic, while the other is sitting idle. Whe...

Overview The transpose function is one of Bosun's more powerful functions, but it also takes effort to understand. It is powerful because it lets us alert at different levels than the tag structure of the underlying data. Transpose changes the scope of your alert. This lets you scope things into l...

Breadth-first-search (BFS) is an algorithm for traversing or searching tree or graph data structures. It starts at the tree root (or some arbitrary node of a graph, sometimes referred to as a 'search key') and explores the neighbor nodes first, before moving to the next level neighbors. BFS was inve...

Most of the time, we'll need to find out the shortest path from single source to all other nodes or a specific node in a 2D graph. Say for example: we want to find out how many moves are required for a knight to reach a certain square in a chessboard, or we have an array where some cells are blocked...

In a const-correct class, all member functions which don't change logical state have this cv-qualified as const, indicating that they don't modify the object (apart from any mutable fields, which can freely be modified even in const instances); if a const cv-qualified function returns a reference, t...

In most text editors, the standard shortcut for saving the current document is Ctrl+S (or Cmd+S on macOS). Vim doesn't have this feature by default but this can be mapped to make things easier. Adding the following lines in .vimrc file will do the job. nnoremap <c-s> :w<CR> inoremap &...

You may want to negate a boolean value, i.e. enter an if statement when a condition is false rather than true. This can be done by using the -Not CmdLet $test = "test" if (-Not $test -eq "test2"){ Write-Host "if condition not met" } You can also use !: $test...

Using the PhantomData type like this allows you to use a specific type without needing it to be part of the Struct. use std::marker::PhantomData; struct Authenticator<T: GetInstance> { _marker: PhantomData<*const T>, // Using `*const T` indicates that we do not own a T } imp...

In SuiteScript 1.0, use nlobjContext.getRemainingUsage() to retrieve the remaining units. An nlobjContext reference is retrieved using the global nlapiGetContext function. // 1.0 var context = nlapiGetContext(); nlapiLogExecution("DEBUG", "Governance Monitoring", "Remai...
