JavaOne4Kids 2015 Wrapup – Devoxx4Kids and Oracle Academy Together!

JavaOne4Kids is focused on promoting technology to next generation of developers; kids who want to learn more about programming, robotics and engineering.

Oracle Academy collaborated with Devoxx4Kids to bring kids content that includes several topics like Minecraft Modding, Java, Python, Scratch, Raspberry Pi, Arduino, NAO robot, LEGO Mindstorms, Greenfoot, Alice, and others at JavaOne 2015.

The attendance grew 3x from last year and it was certainly very heartening to see that!

If you live in/around San Francisco Bay Area, and want a more continued experience through out the year, then its highly recommend to join meetup.com/Devoxx4Kids-BayArea/!

Here are some statistics from the event:

It takes a village to run an event like this. This was certainly not possible without the impeccable support from Oracle team, instructors, and volunteers who helped us through out the event!

Do we expect these kids to come back to again next year? Yes, absolutely!

At least, 88% of them want to come back :)

Minecraft Modding at Schools and Libraries

Introduction to programming languages to kids need to be gamified. They typically seem to like it, and in the process, they  also develop a liking for the language. They also have a better understanding of the typical code and run steps that is common in a software developer’s life.

Getting Started with Java for Kids

As part of Devoxx4Kids, my son and I have been teaching Minecraft Modding workshop for 2+ years now. We’ve personally reached out to 2000+ kids in Bay Area and other parts of the world, and help them write first Hello World program for Java. And its not the conventional public static void main, its a Minecraft Mod. This workshop has also been used at several other Devoxx4Kids chapters around the world.

As part of our workshops, “code” to kids is copy/pasting the text from the website and understanding it. “Build” is just clicking a button in Eclipse bringing Minecraft launcher. Once the game comes up, they know how to play it and see instant modifications. They don’t have to wait for Hello World to appear on their screen. They type “potato” and see a stack of 64 potatoes in their inventor, or they spawn an Ender Dragon from dragon egg or they make skeletons fight with each other. This is the new Hello World!

The installation of JDK, Eclipse or NetBeans, and Forge typically takes ~45 minutes. But after that initial hump, kids are able to build 3-4 mods in a total of ~2 hrs. Our philosophy is more on the lines of teaching them how to think to mod. Yes, we do teach them a few mod but we enable them to create their own mods as well.

Java is often complained about being a verbose language. But Forge decompiled code in Java makes it much easier to read the code, and help kids understand how to change it to make modifications.

The fact that kids love playing the game, this allows the workshop to just leverage their passion and help them in their journey towards becoming a Java programmer. It really helps lowering the average age of Java developer!

Minecraft Modding over Summer

Over the Summer, we delivered Minecraft Modding workshops at:

We were also able to coach some additional volunteers and hopefully spread the Java fever to a wider audience.

Here are some pictures from the event delivered at West Valley San Jose Public Library over the weekend:

Minecon 2015 Wrapup

minecon2015-logo

From a gathering of ~50 people in 2010, Minecon 2015 with 10,000 attendees created a new world record for the biggest convention for a single game.

Minecon 2015 Experience

Do you want to know what what it feels like to be at Minecon?

Minecraft Modding Workshop

Devoxx4Kids was fortunate to give Minecraft Modding workshops to ~200 kids at Minecon 2015. Feedback from all the parents and kids was quite outstanding. Glad we were able to ignite spark in some kids and get them excited in programming, and open source tools like Java, Eclipse, and Minecraft Forge.

Here are a couple of tweets:

All the instructions for minecraft modding are at minecraftmodding.org.

Many thanks to Mark Little and his son Adam, and my son for helping with a successful workshop. Its very important that kids feel comfortable to play with open source tools, and be willing to hack!

Using Mods for Teaching Panel

I also got the opportunity to lead a panel on Using Mods for Teaching with @DorineFlies, @YouthDigital, and @_moonlapse.

Here are some of the questions we addressed:

  1. How are you involved with modding?
  2. How many students/kids have you reached out so far?
  3. What languages/platforms do you use?
  4. Can modding be the right medium for first introduction to programming?
  5. What is an appropriate age to start modding?
  6. What can be done to fundamentally change STEM education in schools?
  7. What would you like from Mojang to improve the modding experience?

The panel was recorded and should be made available at youtube.com/user/TeamMojang/videos. I’ll update this blog when the exact link is available.

Minecraft Youtubers

One of the big craze, and genuine one, in the Minecraft world is about youtubers who produce video of game plays and most of them have 1m+ subscribers. Several of them were attending Minecon and we were fortunate to meet a few of them:

 

As Lydia walked around the main hall, most of the kids were super excited to meet their favorite youtubers!

Minecon 2015 Cape

Every Minecon attendee also get a cape that their in-game character can wear it and show-off the fact you attended a big celebration! Theme for this year was Iron Golem and it looks like as shown:

Minecon 2015 Cape

Minecraft Characters with Snaak

We also met the team behind Snaak and played around with creating some of the Minecraft characters using it.

 

Minecraft and HoloLens

A re-run of HoloLens and Minecraft video was also shown during one of the keynotes, and a preview is available here:

Here is the complete opening ceremony animation:

And the complete photo album:

To me the highlight of the conference was meeting @SeargeDP. If there is one name that is responsible for starting modding in Minecraft, that would be him! Many thanks to him for giving us a chance to deliver minecraft modding workshops at Minecon.

And then, of course, meeting @lexmanos who is the lead developer for Minecraft Forge. We’ve authored an O’Reilly book (targeted at 8+ years old kid) and video on this topic. Several Devoxx4Kids chapters around the world have delivered workshops using the instructions based on Minecraft Forge and explained at minecraftmodding.org.

Check out a nice credential about book from one of the parents we met:

And last, but not the least, many thanks to the Mojang team for keeping the release cadence and supporting different modding communities.

Minecraft is truly a revolutionary game and allows to introduce Java programming to kids at a very early age!

Hopefully we get invited to Minecon 2016 again :)

 

Minecon 2015 – Minecraft Modding Workshop and Education Panel

Devoxx4Kidsminecon 2015
Devoxx4Kids Minecraft Modding workshop has been used all around the world by kids as their first introduction to Java programming, even programming in several cases. This workshop has been delivered at our meetups, corporate events such as OSCON, Silicon Valley Code Camp, JavaOne and Red Hat Summit, schools, libraries, workplaces, homes, and many other venues. And now its going to the most coveted and sought after place for all minecrafters around the world – Minecon 2015!

Many thanks to Microsoft (now the parent company of Mojang) for extending the invitation!

Minecon is the biggest gathering of all minecrafters on this planet. About 10,000 attendees are expected to gather on Jul 4th and 5th in London this year. This will be our first time there. We are super excited and can’t wait to experience the phenomenon.

In addition, Microsoft has also asked us to lead a panel on “Using Mods for Teaching”. This panel will discuss the relevance of modding in education. We’ll try to answer some of the questions as:

  • Can modding be the right medium for first introduction to programming?
  • What is an appropriate age to start modding?
  • What would you like from Mojang to improve the modding experience?
  • What can be done to fundamentally change STEM education in schools?

Participate in Minecon 2015 Virtually

You can participate in Minecon virtually as well!

Are there any questions that you’d like to ask the panelists? Leave a comment in the blog and I’ll try to accommodate as many of them as possible.

As always, follow me @arungupta to watch out for comments/pictures from the event!

Devoxx4Kids Ancillary Event at Corporate

~70 kids were sprawling in a part of the Hynes Convention Center in Boston last Sunday. They were invited by Red Hat to participate in a variety of workshops and get them introduced to technology in a fun way. The workshops were facilitated by Devoxx4Kids instructors and Red Hatters. This is right before the start of Red Hat Summit – a premier open source technology conference for the “big kids”.

The kids had an opportunity to learn the following technologies:

  • MIT App Inventor
  • Greenfoot
  • Minecraft Modding
  • Dr Racket
  • Scratch
  • Flappy Birds

The feedback from all the kids and parents have been very encouraging, and everybody seem to have a great time. Here are some pictures from the event:

 
   
 
 
 
 

Complete set of pictures are:

Number of emails exchanged with the team: Hundreds
Support from the team/instructors/volunteers to run the event: Invaluable
Flight got delayed, stayed up until 3:30 ensuring machines work: Tiring
Kids enjoyed learning how to build the games: Priceless

Overall, it has been quite a joyful and rewarding experience to promote STEM to elementary and middle school kids!

Running a Devoxx4Kids event as an ancillary to the main event is a great way to engage local community. Red Hat Summit is the fourth corporate event in the US (after OSCON 2nd year, JavaOne 2nd year, and Silicon Valley Code Camp) to partner with Devoxx4Kids and give back to the community. Let us know if your corporate event is interested in running a Devoxx4Kids workshop the weekend before/after the main event!

Abstracts

Greenfoot: Lets make some games!

Hey you – yes you – do you like playing video or computer games? Well then how about learning to make your own? Come join us as we hang out for two hours and make some computer games with Greenfoot. Along the way you will learn about computer programming – make your computer do things you want. We will wrap up by showing you some places to go to talk with other people making games and more places to become a more powerful wizard! Be sure to bring a laptop – this will definitely be hands on.

App Inventor

The traditional way to create an application is write code. You type commands, one after another, telling the computer or the smartphone what to do next. When you type commands on a keyboard, it’s easy to make mistakes. What’s more, at a glance, the commands look nothing like the things that you’re getting the computer or smartphone to do. Taken together, the commands are just a bunch of text.

But there’s another way to create an application. With App Inventor, you build instructions by fitting building blocks together with one another on the computer screen. The blocks fit together like jigsaw puzzle pieces. When it’s finished, the whole jigsaw puzzle describes all the commands in your application.

In this workshop, you learn to use App Inventor. You can run your applications on the computers in the lab. You can also install your applications on real Android phones.

Dr. Racket: Don’t dictate, evaluate!

This workshop introduces the basics of functional programming using the Dr. Racket programming environment.

In the first part of the workshop you will learn how to evaluate expressions in the Dr. Racket interpreter, including expressions like <if html were available to display the abstract I’ld show here a racket expression that included an actual devox4 kids image>.

In the second part of the workshop we will work on developing a very simple animation. If time permits we will show how we can make our animations interactive, i.e., have them respond to key presses and mouse clicks.

The workshop is constructed to allow roughly equal amounts of time for experimentation and instruction.

Build your own Flappy Bird

In this workshop you will learn about HTML5, CSS and Javascript by create a game. Together we’re going to build our very own Flappy Bird. We’ll do it step by step and it will be a lot of fun!

Minecraft Modding

Minecraft is a multi-player game about building and placing blocks in a three-dimensional environment. The game allows modifications (known as “mods”) that can change the game from what it was originally written. These mods can add content to the game to alter gameplay. For example, new blocks, mobs, and abilities of player can be added.

Have you always wondered what it takes to write these mods ? This workshop is for you!

In this workshop we’ll teach the kids on how to build Minecraft mods. In the process, they also learn some basic Java concepts as well. No programming experience is required.

Scratch

Scratch (scratch.mit.edu) makes it easy to create interactive stories, animations, games, music, and art, and share these creations on the web. You will create several fun and interesting Scratch programs. No programming experience or typing skill is required.

Volunteer

Are you living in/around Boston area? Interested in becoming a volunteer?

No programming experience is required, some familiarity with computers would be useful. You’ll be required to listen to the instructor and help the attendees follow along.

Minecraft Server on Google Cloud – Tech Tip #82

Minecraft Logo

Bukkit Logo

If you’ve not followed the Minecraft/Bukkit saga over the past few months, Bukkit and CraftBukkit downloads were taken down by DMCA because a developer (@wolvereness) wanted Mojang to open up. Mojang (@vubui) posted an official statement in their forums. The general feeling is that @wolvereness left the Bukkit community hanging, and Mojang is not responsible for this debacle.

One of my friends (@ryanmichela), and a contributor to Bukkit, prepared a slide deck explaining the unfortunate debacle:

Anyway, leaving all the gory details behind, this blog will show how to get started with Bukkit 1.8.3.

What?

You just said, Bukkit was shutdown by DMCA.

SpigotMC LogoHail Spigot for reviving Bukkit, and updating to 1.8.3!

Its still not clear how did Spigot get around DMCA shutdown but the binaries seem to be available again, at least for now.

As a refresher, Bukkit is the API used by developers to make plugins. CraftBukkit is the modified Minecraft server that can understand plugins made by the Bukkit API.

Minecraft Server Hosting on OpenShift already explained how to setup a Minecraft server on OpenShift. This Tech Tip will show how to get a Minecraft server running on Google Cloud.

Lets get started!

Get Started with Google Cloud

Google Cloud Platform logo

  1. Sign up for a free trial at cloud.google.com. This gives you credit of $300, which should be pretty decent to begin with.

Create and Configure Google Compute Engine

  1. Go to console.developers.google.com and create a new project by specifying the values as shown:Create Project on Google Cloud
  2. In console.developers.google.com, go to “Compute”, “Compute Engine”, “Networks”, “default”, “New firewall rule” and enter the values as shown and click on “Create”.Google Cloud Firewall Rule
  3. In the left menu bar, click on “VM Instances” under “Compute Engine”, “Create instance”. Take everything default except:
    1. Provide a name as “minecraft-instance”
    2. Change Image to Ubuntu 14.10.
    3. Change External IP to “New static IP address” and fill in the details. IP address is automatically assigned.

    Exact values are shown here:

    Google Cloud Create Instance

    And click on “Create”.

    Note down the IP address, this will be used later to connect from Minecraft launcher.

  4. Click on the newly created instance, “Add tags”, and specify “minecraft” tag. Exact same tag on the VM instance and Firewall rule ensures that the rule is applied to the appropriate instance.

Install JDK, Git, and Spigot

In console.developers.google.com, select the recently created instance, click on “SSH”, “Open in browser window”. The software is installed in the shell window.

Install JDK

Make sure to answer questions and accept license during the install. Using OpenJDK 8 to install Spigot gives the following exception:

Install Git

This is required for installing Spigot.

Install Spigot

Download and Install Spigot

A successful completion of this task shows the following message:

Start Minecraft Server on Google Cloud

Run the server as:

This will generate “eula.txt”. Accept license agreement by giving the following command:

Run server as:

This will start the CraftBukkit 1.8 server in background.

Connect to Minecraft Server from the Client

Launch Minecraft client and create a new Minecraft server as:

Google Cloud Minecraft Multiplayer

Clicking on Done shows:

Google Cloud Multiplayer Minecraft Server

Now your client can connect to the Minecraft server running on Google Cloud.
Google Cloud Minecraft Client

The server is now live. Add 104.155.38.193  to your Minecraft launcher and put some Google resources to test :)

I was hoping to provide a script that can be run using Google Cloud SDK but the bundled CLI seems to have some issues creating the project. CLI equivalent for other commands can be easily seen from the console itself.

Enjoy and happy Minecrafting!

Minecraft Modding Course at Elementary School – Teach Java to Kids

Cross posted from weblogs.java.net/blog/arungupta/archive/2015/03/22/minecraft-modding-course-elementary-school-teach-java-kids

minecraft-logo

Exactly two years ago, I wrote a blog on Introducing Kids to Java Programming using Minecraft. Since then, Devoxx4Kids has delivered numerous Minecraft Modding workshops all around the world. The workshop material is all publicly accessible at bit.ly/d4k-minecraft. In these workshops, we teach attendees, typically 8 – 16 years of age, how to create Minecraft Mods. Given the excitement around Minecraft in this age range, these workshops are typically sold out very quickly.

One of the parents from our workshops in the San Francisco Bay Area asked us to deliver a 8-week course on Minecraft modding at their local public school. As an athlete, I’m always looking for new challenges and break the rhythm. This felt like a good option, and so the game was on!

My son has been playing the game, and modding, for quite some time and helped me create the mods easily. We’ve also finished authoring our upcoming O’Reilly book on Minecraft Modding using Forge so had a decent idea on what needs to be done for these workshops.

Minecraft Modding Workshop Material

All the workshop material is available at bit.ly/d4k-minecraft.

Getting Started with Minecraft Modding using Forge shows the basic installation steps.

These classes were taught from 7:30am – 7:45am, before start of the school. Given the nature of workshop, the enthusiasm and concentration in the kids was just amazing.

Minecraft Modding Course Outline

The 8 week course was delivered using the following lessons:

Week LESSON Java concepts
1 Watch through the video and understand the software required for modding Familiarity with JDK, Forge, Eclipse
2 Work through the installation and get the bundled sample mod running. This bundled mod, without any typing, allows to explain the basic concepts of Java such as class, packages, methods, running Minecraft from Eclipse, seeing the output in Eclipse panel.
3 Chat Items mod shows how to create a stack of 64 potatoes if the word “potato” is typed in the chat window.
  • Create a new class in Eclipse
  • Annotations and event-driven programming to listen for events when a player types a message in the chat window is introduced.
  • String variable types and how they are enclosed within a quotes is introduced.
4 Continue with Chat Items mod and a couple of variations. Change the number of items to be generated. Generate different items on different words, or multiple items on same word.
  • Integer variables for changing the number of items.
  • How  use Eclipse allows code completion and scroll through the list of items that can be generated.
  • Multiple if/else blocks and scope of a block.
5 Eclipse Tutorial for Beginners Some familiarity with Eclipse
6 Ender Dragon Spawner mod spawns an Ender Dragon every time a dragon egg is placed.
  •  == to compare objects

Most of the kids in this 8-week course had no prior programming experience. And it was amazing to see them be able to read the Java code by week 7. Some kids who had prior experience finished the workshop in first 3-4 weeks, and were helping other kids.

Check out some of pictures from the 8-week workshops:

Many thanks to attendees, parents, volunteers, Parent Teacher Association, and school authorities for giving us a chance. The real benchmark was when all the kids raised their hands to continue workshop for another 8 weeks … that was awesome!

Is Java difficult as kids first programming language?

One of the common questions asked during these workshops is “Java is too difficult a language to start with”. Most of the times these questions are not based on any personal experience but more on the lines my-friend-told-me-so or i-read-an-article-explaining-so. My typical answer consists of the following parts:

  1. Yes, Java is a bit verbose, but was designed to be readable by humans and computer. Ask somebody to read Scala or Clojure code at this age and they’ll probably never come back to programming again. These languages serve a niche purpose, and their concepts are now anyway getting integrated into the mainstream language already.
  2. Ruby, Groovy, and Python are alternative decent languages to start with. But do you really want to start teaching them fundamental programming using Hello World.
  3. Kids are already “addicted” to Minecraft. Game is written using Java and modding can be done using Java. Lets leverage that addiction and convert that into their passion for programming. Minecraft provides a perfect platform for gamification of programming experience at this early age.
  4. There are 9 million Java developers. It is a very well adopted and understood language, with lots of help in terms of books, articles, blogs, videos, tools, etc. And the language has been around for almost 20 years now. Other languages come and go, but this is the one to stay!

As Alan Kay said

The best way to predict the future is to create it

Lets create some young Java developers by teaching them Minecraft modding. This will give them bragging rights in their friends, parents a satisfaction that their kids are learning a top notch programming language, and budding Java developers to the industry.

I dare you to pick up this workshop and run in your local school :)

Here is another wonderful video created (@BertBreeman):

It takes a village to run an event like this. This was certainly not possible without the impeccable support from Oracle team, JUG leaders, Java Champions, and several other volunteers who helped us through out the team!

This summarizes the event for me:
