When creating a std::unique_lock, there are three different locking strategies to choose from: std::try_to_lock, std::defer_lock and std::adopt_lock std::try_to_lock allows for trying a lock without blocking: { std::atomic_int temp {0}; std::mutex _mutex; std::thread t( [&...

Left join returns all the observations in the left data set regardless of their key values but only observations with matching key values from the right data set. Considering the same example as above, PROC SQL; CREATE TABLE C AS SELECT A.*, B.CC_NUMBER, B.START_DATE FROM CUSTOMER A LEFT JOIN CC...

Full join selects all the observations from both data sets but there are missing values where the key value in each observation is found in one table only. PROC SQL; CREATE TABLE C AS SELECT A.*, B.CC_NUMBER, B.START_DATE FROM CUSTOMER A FULL JOIN CC_DETAILS B ON A.CUSTOMERID=B.CUSTOMERID QUI...

Many biological questions can be translated into a DNA sequencing problem. For instance, if you want to know the expression level of a gene you can: copy its mRNAs into complementary DNA molecules, sequence each of the resulting DNA molecules, map those sequences back to the reference genome, and th...

In brief: Properties make it easy to pass updates from the python side to the user interface Binding passes the changes that happened on the user interface to the python side. from kivy.app import App from kivy.uix.boxlayout import BoxLayout from kivy.lang import Builder from kivy.properti...

Most kivy apps start with this structure: from kivy.app import App class TutorialApp(App): def build(self): return TutorialApp().run() There is several way to go from here : All the codes below (except example 1 and 3) have the same widget and similar features, but show diffe...

First, we create an empty map, and insert some elements into it: Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<>(); Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<Integer, String>(); treeMap.put(10, "ten"); treeMap.put(4, "fou...

First, we create an empty set, and insert some elements into it: Java SE 7 TreeSet<Integer> treeSet = new TreeSet<>(); Java SE 7 TreeSet<Integer> treeSet = new TreeSet<Integer>(); treeSet.add(10); treeSet.add(4); treeSet.add(1); treeSet.add(12); Once we hav...

Since TreeMaps and TreeSets maintain keys/elements according to their natural ordering. Therefor TreeMap keys and TreeSet elements have to comparable to one another. Say we have a custom Person class: public class Person { private int id; private String firstName, lastName; priva...

TreeMap and TreeSet are not thread-safe collections, so care must be taken to ensure when used in multi-threaded programs. Both TreeMap and TreeSet are safe when read, even concurrently, by multiple threads. So if they have been created and populated by a single thread (say, at the start of the pro...

OnInit: this is really amazing thing in ionic2 or we can say in AngularJs2. With the same above example we can see what is ngOnInit is. So you are ready with the service method, now in your view/page you want that student list data available as soon as your view is going to appear, this should be th...

export class HomePage implements OnInit { ... .... constructor(....){} ngOnInit(){ this._studentService.getAllStudents().subscribe( (students: Students[]) => this.students = students, )

Log into a Google Account and click New > More > Google Forms. Build the form fields required using the editor. If the form was built with an account that is part of an organisation then click on the cog and unselect the option that only members can complete the form. Set the form to save t...

This is done by adding a button, dialog box and iframe as explained below. The examples below use MDL for look and feel because it is used by Google forms and so it makes the additional elements look fairly seamless. Dialog boxes may require a polyfill if you plan to support older browsers.

Add a new function called showGoogleForm and adapt the follow code to suit. Note for simplicity this example does not contain any error checking which should be added in a production environment. The url should look something like this: https://docs.google.com/forms/.../?usp=pp_url&entry.17391...

To work with Json using C#, it is need to use Newtonsoft (.net library). This library provides methods that allows the programmer serialize and deserialize objects and more. There is a tutorial if you want to know details about its methods and usages. If you use Visual Studio, go to Tools/Nuget P...
