Fedora 28 Workstation ships with a feature that allows you to quickly search, select and input emoji using your keyboard. Emoji, cute ideograms that are part of Unicode, are used fairly widely in messaging and especially on mobile devices. You may have heard the idiom “A picture is worth a thousand words.” This is exactly what emoji provide: simple images for you to use in communication. Each release of Unicode adds more, with over 200 new ones added in past releases of Unicode. This article shows you how to make them easy to use in your Fedora system.

It’s great to see emoji numbers growing. But at the same time it brings the challenge of how to input them in a computing device. Many people already use these symbols for input in mobile devices or social networking sites.

[Editors’ note: This article is an update to a previously published piece on this topic.]

Enabling Emoji input on Fedora 28 Workstation

The new emoji input method ships by default in Fedora 28 Workstation. To use it, you must enable it using the Region and Language settings dialog. Open the Region and Language dialog from the main Fedora Workstation settings, or search for it in the Overview.

Choose the + control to add an input source. The following dialog appears:

Choose the final option (three dots) to expand the selections fully. Then, find Other at the bottom of the list and select it:

In the next dialog, find the Typing booster choice and select it:

This advanced input method is powered behind the scenes by iBus. The advanced input methods are identifiable in the list by the cogs icon on the right of the list.

The Input Method drop-down automatically appears in the GNOME Shell top bar. Ensure your default method — in this example, English (US) — is selected as the current method, and you’ll be ready to input.

Using the new Emoji input method

Now the Emoji input method is enabled, search for emoji by pressing the keyboard shortcut Ctrl+Shift+E. A pop-over dialog appears where you can type a search term, such as smile, to find matching symbols.

Use the arrow keys to navigate the list. Then, hit Enter to make your selection, and the glyph will be placed as input.

A key goal in my career is growing the understanding and best practice of how communities, and open source communities in particular, can work well together. There is a lot of nuance to this work, and the best way to build a corpus of best practice is to bring people together to share ideas and experience.

In service of this, last year I reached out to The Linux Foundation about putting together an event focused on these “people” elements of Open Source such as community management, collaborative workflow, governance, managing conflict, and more. It was called the Open Community Conference, which took place at the Open Source Summit events in Los Angeles and Prague, and everything went swimmingly.

This train though, has to keep moving, and we realized that the scope of the event needed broadening. What about legal, compliance, standards, and other similar topics? They needed a home, and this event seemed like a logical place to house them. So, in a roaring display of rebranding, we renamed the event to the Open Collaboration Conference. It happens again at the Open Source Summit, this year in Vancouver from August 29-31 and then in Edinburgh from October 22-24, 2018.

The upcoming event in Vancouver is looking fantastic. Just like last year, we had a raft of submissions, so thanks everyone for making my job (rightly) difficult for choosing the final set of talks.

Featured Talks

Unsurprisingly, we have some really remarkable speakers, from a raft of different organizations, backgrounds, and disciplines. This includes:

• 10 Pragmatic Lessons for Building Data Collaboration – Patrick McGarry, data.world

• Developing a Culture of Mentorship – Tessa Kriesel, Pantheon

• Creating a Positive Compliance Program – Nithya Ruff & Krista Khare, Comcast

• How to Pay Your Contributors and Get Away with It – Erlend Sogge Heggen, Discourse

• Lessons Learned Building Messaging Software with a Fully Remote Team – Corey Hulen, Mattermost

• Open Source Compliance: Reworking Internal Processes – Meng Chow & Aida Rivas, VMware

• Improving the Development Process with Metrics-Driven Insights – Jack Humphrey, Indeed

• Why “Go social” and How to Communicate using Social Media – Arpana Durgaprasad, IBM

• Developing an Inner-source Model for Your Enterprise – Martin Brodbeck, Shutterstock

• Going from Appointed to Elected: Evolving Technical Community Leadership – Daniel Farrell, Red Hat

• The Label Does Not Make it a “Good First Issue” – Linea Brink Andersen, Student

• Rebooting a Project – Amye Scavarda, Red Hat

Oh, and I will be speaking, too, delivering a new presentation called “Building Effective Community Leaders: A Guide.” It will cover key principles of leadership and how to bake them into your community, company, or other organization.

In addition to this, don’t forget the fantastic networking, evening events, and other goodness that will be jammed into an exciting few days. As usual, this all takes place at the Open Source Summit, and you view the whole schedule and learn more about how to join us at https://events.linuxfoundation.org/events/open-source-summit-north-america-2018/.

Finally, I will be there for the full event. If you want to have a meeting, drop me an email to jono@jonobacon.com.

The Sims Mobile has pulled in over $15 million in global revenue since launching on March 6. 

That’s according to a brief report from analytics outfit Sensor Tower, which revealed that approximately 59 percent of that worldwide revenue came from the United States. 

The UK was the second most lucrative region for the free-to-play title, but it was some distance behind the States with only 8 percent of player spending taking place on British soil. 

Despite being the new kid on the block, The Sims Mobile is still being outshone by its predecessor The Sims FreePlay, which brought in twice as much revenue as Mobile during June. 

Of course, FreePlay does have something of a head start on its younger sibling, having launched all the way back in 2012.

Objective

The main objective of this blog post is to give you an idea about how to use C# Events in Unity.

What is problem with Delegates?

What is an Event?

Why Events are used?

How to declare an Event?

You may have all these questions in your mind.

Don’t worry, you are at the right place.

Let’s start, Do you remember the problem of Delegates?

If we use a single delegate after the use of multicast delegates then it will reset the existing invocation list.

This situation is very difficult to track if multiple classes subscribe to the same delegate.

This is the reason why we have Events.

Let’s see how they work.

Events are a type of special delegates which are used when you want to notify other classes when something happens. Like, on GameStart, on Gameover.

Let’s take a look on declaration and use of an Events.

1. Declare a Delegate

public delegate void OnGameStart();

2.Create an Event

public static event OnGameStart onGameStart;

3. Point to method

onGameStart += Move;

4. Invoke an Event

onGameStart ();

Let’s, create a simple game using Event Delegate.

Step 1

• Create an empty GameObject name it as you like.

Step 2

• Create C# script name it EventManager.

Write following code in EventManager.cs

public class EventManager : MonoBehaviour {
 public delegate void OnButtonClick();
 public static event OnButtonClick onButtonClick;
 public void RaiseOnButtonClick() {
 if (onButtonClick != null) {
 onButtonClick();
 }
 }
 }

Step 3

• Assign it to an empty GameObject.

Step 4

• Create a 2d object and assign knob as sprite in SpriteRenderer.

Step 5

• Create  C# script name PlayerTransformAndColor.

Write following code in PlayerTransformAndColor.cs

public class PlayerTransformAndColor : MonoBehaviour {
 
 public SpriteRenderer spriteRenderer;
 public Color color1, color2;
 private void OnEnable()
 {
 EventManager.onButtonClick += ChangePosition;
 EventManager.onButtonClick += ChangeColor;
 }
 public void ChangePosition() {
 transform.position += Vector3.one * 2;
 }
 public void ChangeColor() {
 spriteRenderer.color = color2;
 }
 }

Step 6

• Assign it to empty GameObject.

Now let’s do some changes in PlayerTransformAndColor.cs

public class PlayerTransformAndColor : MonoBehaviour {
 public SpriteRenderer spriteRenderer;
 public Color color1, color2;
 private void OnEnable()
 {
 EventManager.onButtonClick += ChangePosition;
 EventManager.onButtonClick += ChangeColor;
 EventManager.onButtonClick = ChangeRotation;
 }
 public void ChangePosition() {
 transform.position += Vector3.one * 2;
 }
 public void ChangeColor() {
 spriteRenderer.color = color2;
 }
 public void ChangeRotation() {
 transform.Rotate(0, 90, 0);
 }
 
 }

You may find the error. Like shown in below,

Got the  idea, How Events overcome the problem of Delegates.??

Events adds a layer of abstraction and protection on delegate, this protection prevents client of the delegate from resetting the delegate and invocation list.  

Now let’s take one more practical example. That gives you more clear idea about how event handle multiple event listeners by only one event Invocation.

For this, we’ll follow these steps.

Step 1

• Create an empty GameObject name it EventManager.

Step 2

• Create C# scrip and name it Eventmanager.

Write following code in EventManager.cs

public class EventManager : MonoBehaviour {
 public delegate void OnRest(); //Declare a Delegate
 public static event OnRest onReset; //Create an Event
 public delegate void OnReStart(); //Declare a Delegate
 public static event OnReStart onReStart; //Create an Event
 public static void RaiseOnReset()
 {
 if (onReset != null)
 {
 onReset(); //Invoke an Event
 }
 }
 public static void RaiseOnReStart()
 {
 if (onReStart != null)
 {
 onReStart(); //Invoke an Event
 }
 }


}

Step 3

• Assign it to an empty GameObject(EventManager).

Step 4

• Create an empty GameObject name it EventHandler.

Step 5

• Create C# script name it EventHandler

Write following code in EventHandler.cs

public class EventHandler : MonoBehaviour


{
 void Update()
 {
 if (Input.GetKeyDown(KeyCode.P))
 {
 EventManager.RaiseOnReset(); // Function call to invoke an Event
 }
 else if (Input.GetKeyDown(KeyCode.S))
 {
 EventManager.RaiseOnReStart(); // Function call to invoke an Event
 }
 }


}

Step 6

• Assign it to an empty Gameobject(EventHandler).

Step 7

Create a 3D game object(Cube).

Step 8

• Create C# script name it ObjectMotion.

Write following code in ObjectMotion.cs

 public class ObjectMotion : MonoBehaviour
 {
 private float minRange, maxRange;
 private float speed, restartSpeed;
 private Vector3 newPosition;
 private void OnEnable()
 {
 EventManager.onReset += Reset;
 EventManager.onReStart += Restart;
 }
 void Start()
 {
 minRange = 1;
 maxRange = 3;
 speed = Random.Range(minRange, maxRange);
 restartSpeed = speed;
 }
 void Update()
 {
 newPosition = transform.position;
 newPosition.x = Mathf.Sin(Time.time) * speed;
 transform.position = newPosition;
 }
 private void OnDisable()
 {
 EventManager.onReset -= Reset;
 EventManager.onReStart -= Restart;
 }
 public void Reset()
 {
 speed = 0;
 }
 public void Restart()
 {
 speed = restartSpeed;
 }
 }

Step 9

• Assign it to 3D GameObject(Cube).

Now create multiple copies of 3D GameObject.

Run Unity, and press “P” to reset the position and “S” to restart the motion.

From the above examples we may come to the  following conclusion,
