Open a terminal and run: sudo apt-get install arduino Open the Arduino application, or type arduino into the terminal

zo opens a fold underneath the cursor. zO opens all folds underneath the cursor, recursively. zc closes a fold underneath the cursor. zC closes all folds underneath the cursor, recursively. za toggles a fold under the cursor (a closed fold is opened, an opened fold is closed). zM closes all f...

zv will ensure the line containing the cursor is not folded. The minimum number of folds required to expose the cursor line will be opened.

library(RODBC) con <- odbcDriverConnect("driver={Sql Server};server=servername;trusted connection=true") dat <- sqlQuery(con, "select * from table"); close(con) This will connect to a SQL Server instance. For more information on what your connection string should loo...

Applying css intuitively doesn't produce the desired results because vertical-align:middle isn't applicable to block-level elements margin-top:auto and margin-bottom:auto used values would compute as zero margin-top:-50% percentage-based margin values are calculated relative to the width of ...

The diamond problem, or multiple inheritance, is handled by Scala using Traits, which are similar to Java interfaces. Traits are more flexible than interfaces and can include implemented methods. This makes traits similar to mixins in other languages. Scala does not support inheritance from multipl...

var go = GameObject.Find("NameOfTheObject"); ProsConsEasy to usePerformance degrades along the number of gameobjects in sceneStrings are weak references and suspect to user errors

var go = GameObject.FindGameObjectWithTag("Player"); ProsConsPossible to search both single objects and entire groupsStrings are weak references and suspect to user errors.Relatively fast and efficientCode is not portable as tags are hard coded in scripts.

[SerializeField] GameObject[] gameObjects; ProsConsGreat performanceObject collection is staticPortable codeCan only refer to GameObjects from the same scene

ExampleScript script = GameObject.FindObjectOfType<ExampleScript>(); GameObject go = script.gameObject; FindObjectOfType() returns null if none is found. ProsConsStrongly typedPerformance degrades along the number of gameobjects needed to evaluatePossible to search both single objects...

The table shows a list of currently supported release showing both original distribution releases (e.g. Ubuntu 14.04) and point releases (e.g. 14.04.3).

By overloading the indexer you can create a class that looks and feels like an array but isn't. It will have O(1) get and set methods, can access an element at index 100, and yet still have the size of the elements inside of it. The SparseArray class class SparseArray { Dictionary<...
