Single-quotes are literal strings, and the lack of escape characters means that the only character that can not occur inside of a single-quoted string is a single-quote. $ echo '$var \$var \\$var \\\$var' $var \$var \\$var \\\$var $ echo '"quoted string"' "quoted string" $ e...

Double-quotes preserve all characters other than " terminator, $ expansions, ` command substitutions, and \ escapes of any of these characters (and newline removal). Note that the literal \ is preserved unless followed by a special character. General escapes: $ printf "\"quoted str...

The Jenkins Pipeline DSL is used as an example for such a language: node { git 'https://github.com/joe_user/simple-maven-project-with-tests.git' def mvnHome = tool 'M3' sh "${mvnHome}/bin/mvn -B -Dmaven.test.failure.ignore verify" archiveArtifacts artifacts: '**/target/*.jar',...

For accessing Cassandra cassandra-driver module from DataStax can be used. It supports all the features and can be easily configured. const cassandra = require("cassandra-driver"); const clientOptions = { contactPoints: ["host1", "host2"], keyspace: "te...

This basic Lucene example creates a simple index, and searches on it. Note: RAMDirectory creates a memory-resident index, and is handy for experimenting and testing, but in practice most people will need to have an index stored in the file system (see FSDirectory.open). import java.io.IOException...

Sometimes, it can be difficult to find the mathematical symbol you need. There are several options here. The first (and quickest) is to use Detexify, where you draw the symbol you'd like, and it tries to find what you want, like as shown below: Another option is to use the comprehensive LaTeX sym...

While standard LaTeX is all that is needed for most simple mathematical formulae and equations, sometimes more symbols and tools are needed. There are multiple packages available that will enhance your equations and provide you with more to work with. Three of the main packages are described below. ...

Let's say you cannot find the symbol you need anywhere. You can create a custom symbol. For example, the code \documentclass{article} \usepackage{graphicx,amsmath,amssymb} \DeclareRobustCommand{\diamondtimes}{% \mathbin{\text{\rotatebox[origin=c]{45}{$\boxplus$}}}% } \begin{document} $a\d...

//Add value to Isolated Storage Settings IsolatedStorageSettings.ApplicationSettings.Add("Key", "Value");

//Check if a value exists in settings already if (IsolatedStorageSettings.ApplicationSettings.Contains("Key")) { //perform logic }

string setting = IsolatedStorageSettings.ApplicationSettings["Key"] as string;

By default, Jsoup will display only block-level elements with a trailing line break. Inline elements are displayed without a line break. Given a body fragment, with inline elements: <select name="menu"> <option value="foo">foo</option> <option va...

The gridspec package allows more control over the placement of subplots. It makes it much easier to control the margins of the plots and the spacing between the individual subplots. In addition, it allows for different sized axes on the same figure by defining axes which take up multiple grid loca...

Package TikZ lends itself very well to drawing graphs. This is a small example (requires TikZ 3.0+): \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{positioning,arrows.meta} \begin{document} \begin{tikzpicture}[auto,vertex/.style={draw,circle}] \node[vertex] (a) {A}; ...

TikZ implements several algorithms for automatic graph layouts (requires LuaLaTeX). \documentclass{article} \usepackage{tikz} \usetikzlibrary{graphs,graphdrawing,quotes} \usegdlibrary{force} \begin{document} \begin{tikzpicture} \graph[spring layout] { A -> ["1"...

Thorup's algorithm for single source shortest path for undirected graph has the time complexity O(m), lower than Dijkstra. Basic ideas are the following. (Sorry, I didn't try implementing it yet, so I might miss some minor details. And the original paper is paywalled so I tried to reconstruct it fr...

ls shows files and directories in present working directory. (if no arguments are passed.) (It doesn't show hidden files which starts with . by default.) user@ubuntu14:/usr$ ls bin games include lib lib32 local sbin share src To see all files (hidden files/folders also). Use ls -a OR l...
