The most important AppWidgetProvider callback is onUpdate(). It is called everytime an appwidget is added.
public class ExampleAppWidgetProvider extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = a...
This is MATLAB's long-winded way of saying that it cannot find the function that you're trying to call. There are a number of reasons you could get this error:
That function was introduced after your current version of MATLAB
The MATLAB online documentation provides a very nice feature which allow...
In Terminal on your Mac operating system, enter the following 2 commands:
lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom | while read f; do sudo rm /usr/local/${f}; done

First we need to reference the Styles we want to use.
<link rel="stylesheet" href="[file path]/kendo.common.min.css" />
<link rel="stylesheet" href="[file path]/kendo.[Theme].min.css" />
Now most of the controls use the [Theme], given in the a...
Since Unity 5.2.5 it's possible to use RuntimeInitializeOnLoadMethodAttribute to execute initialization logic bypassing MonoBehaviour order of execution. It provides a way to create more clean and robust implementation:
using UnityEngine;
sealed class GameDirector : MonoBehaviour
{
// Beca...
The reason you do not have to override Awake, Start, Update and other method is because they are not virtual methods defined in a base class.
The first time your script gets accessed, the scripting runtime looks through the script to see if some methods are defined. If they are, that information is...
Suppose, your users and/or groups have profiles and you want to display address profile fields on a google map.
# app/models/profile_fields/address.rb
class ProfileFields::Address < ProfileFields::Base
# Attributes:
# label, e.g. "Work address"
# value, e.g. "Willy-Bran...
Suppose, there is a .google_map div, which will become the map, and which has the address fields to show as markers as data attribute.
For example:
<!-- http://localhost:3000/profiles/123 -->
<div class="google_map" data-address-fields="[
{label: 'Work address', value: ...
Provided an App.GoogleMap coffee script class, the google map can be initialized like this:
# app/assets/javascripts/google_maps.js.coffee
# ...
class App.GoogleMap
map_div: {}
map: {}
constructor: (map_div)->
@map_div = map_div
@init_map()
@reference_the_map_as_dat...
Provided an App.GoogleMap coffee script class and the marker information being stored in the data-address-fields attribute of the .google_map div, the map markers can be initialized on the map like this:
# app/assets/javascripts/google_maps.js.coffee
# ...
class App.GoogleMap
# ...

Sometimes it can be useful to set your application locale based upon the request IP. You can easily achieve this using Geocoder. Among the many things Geocoder does, it can also tell the location of a request.
First, add Geocoder to your Gemfile
# Gemfile
gem 'geocoder'
Geocoder adds location...
Rails have very easy way to get first and last record from database.

User.first
It will generate following sql query:
SELECT `users`.* FROM `users` ORDER BY `users`.`id` ASC LIMIT 1
And will return following recor...
In order to compile and run SystemVerilog code a tool called a simulator is needed. Most commonly, commercial tools from one of the Big Three EDA companies is used:
Cadence Incisive
Mentor Graphics QuestaSim
Synopsys VCS
Other EDA vendors also provide simulators:
Aldec Riviera-PRO
Xilinx...
The Set object lets you store unique values of any type, whether primitive values or object references.
You can push items into a set and iterate them similar to a plain JavaScript array, but unlike array, you cannot add a value to a Set if the value already exist in it.
To create a new set:
cons...
To add a value to a Set, use the .add() method:
mySet.add(5);
If the value already exist in the set it will not be added again, as Sets contain unique values.
Note that the .add() method returns the set itself, so you can chain add calls together:
mySet.add(1).add(2).add(3);
To remove a value from a set, use .delete() method:
mySet.delete(some_val);
This function will return true if the value existed in the set and was removed, or false otherwise.
