cardboardCardboard has been a part of childhood learning for a very long time, however its use has evolved from building things, making dens or sliding down grassy hills on it. The evolution on how this material is being used in learning is changing at a fast rate.

Google have been leading the way with the Google Cardboard Viewer that you can put your phone in and experience Virtual Reality at a low cost (phone excluded). There is now an increase of  cardboard kits available and coming on to the market, especially with kits like the Raspberry PI.

Here are some of the kits:

Having the Right Digital Mindset

Digital BrainDigital is used as a title to cover the current business and computing era. Being Digital is about having the right mindset. There is no magic course or exam that you can take that will pronounce you as being “Digital”. Its how you apply yourself against the changing landscape of business and technology.

There area many areas that could be included to help shape your Digital Mindset, however for me these fit into six main areas:

The Digital Era is enabling “A Growth Mindset in the Age of Abundance”.

Business

The business area covers the skills and thinking that are needed in your workplace and what you need to succeed. Businesses are being constantly challenged in the way that they operate today and look forward to tomorrow against what their customers demand, the market wants and competition are doing.

There may be a number of business processes that are in place that have been there for a while and are expensive to change constrained by a number of factors. This has meant that the processes haven’t grown. The changes that the digital era is bringing helps to remove these constraints and costs, allowing business to rethink how they achieve these processes. With the constraints being removed through innovation and advancements, with costs coming down, how can you change/transform these processes to meet the market challenges of today. What can you change/transform/automate?

Technology

The technology area covers existing, new and emerging technologies in your life. What you use in everyday life and what you could use or imagine that would help you complete tasks and achieve goals quickly and efficiently. Defining which technologies you should be using and learning will depend partly on what your job role is and the road maps and trends for the industry/sector. The aaS (as a Service)  economy is providing the ability to consume technology at a faster easier route with an abundance of choice of service to go with. The need for a growth mindset is key to navigating a direction and path through this and making decisions on which technologies best meet your needs. The key is to understand and keep up with the trends and technologies.

Social

The social area covers how you interact with the rest of the world, including your work and family life. Reading everything that is going on Social Media is literally “drinking from the fire hose” – so much happening you can get easily swamped with noise.  Building a Personal Knowledge Management System is one way of keeping in touch with what is happening and trending on topics that you are interested in on Social Media. Setting yourself a series of Social Media Rules will help define when and what you should put in the public domain and when not to.

Personal

The personal area covers yourself. Ensuring that your health is good and you are living life to the full or best you can helps. Eating well and keeping fit help keep the mind fresh and positive.

Understanding that change is happening everyday and we need to embrace this with a positive attitude and work through the ambiguity that it presents. A blog post by Richard Branson recently wraps this up nicely “You can’t control what happens to you but you can control how you react”

Fear of failure is another area that often lets us down and stops us from trying things, however we can learn from our mistakes so it is important to experiment and innovate. Doing small things and trying them – Theory of small bets – allows you to fail fast if things don’t work and keep any cost/consequences small. “Successful entrepreneurs don’t begin with brilliant ideas — they discover them.” ~ Peter Sims

Application

The application area covers how you apply these mindset areas into your everyday life using method that are well documented such as Agile and Design Thinking. The key is choosing the right method for the situation you are in. Using aids to help you may be one way of doing this – Playing a game with innovation and thinking.

Learning

One of the biggest areas is learning. Keeping your skills up to date with the latest advancements in all the areas above. You should be looking to do 50 to 60 hours learning a year as a minimum (some professions require higher number of hours). Learning is easier with the internet through online courses, videos and podcasts allowing it to be undertaken at anytime. Re-enforcing your learning through explaining it to someone else or blogging about it is part of  The Nature and Cycle of CPD.

There are arguments for and against learning to code, however having an understanding of what is going on in the coding world helps with today’s advancing technology.

Yesterday I attended GitHub Satellite 2017 in LondonGithub

https://github.com/blog/2313-join-us-for-github-satellite-2017-may-22-23-in-london-uk

The event was well attended and there was a good buzz around the conference. GitHub Marketplace was launched at the conference and some of the initial vendors in the Marketplace demonstrated how their applications can be used in the lifecycle of coding. You could watch demos and chat to the companies at their vendor stalls to gain further information.

Below are my notes from the conference and Key Note opening speeches

  • Using bots in Integrations

GitHub Marketplace (Launching today)

  • Find tools that meet your workflows best.
  • Pricing plans in marketplace
  • Marketplace has option to join and apply to be part of Marketplace.

Build and Grow Sessions

There were a number of sessions held in either the Build or Grow track which attendees could join.

I went to sessions in both tracks including the session on Building Interconnected Workflows which featured companies in the newly launched Market Place. Heard from these companies on how their products could be used in conjunction for a full code project lifecycle, which was interesting and good to hear.

Vitor Monteiro, GitHub
Andrew Homeyer, Waffle.io
Danielle Tomlinson, CircleCI
Jaime Jorge, Codacy
Cory Virok, Rollbar

There was a good session on Women in IT from Amy Dickens from the University of Nottingham which also covered topics of diversity and how workplaces and attitudes can change to make a difference.

Closing Session

The closing session was run by Marc Scott from the Raspberry PI Foundation who gave an overview of the Foundation, what it does and how the community can help review projects and sumbit projects for others to practice, learn from and enjoy. Also helping by joining local coding groups to pass on knowledge.

Sessions were streamed and Im hoping that replays are availble to catch up with the sessions I couldnt get to.

Unfortunately I could not get to todays workshop sessions but again hoping for streams of these following the event.

How you can begin to Code

code1With all the recent STEM activities I have been involved with and blogged about, I have been asked to write some posts around how someone can start learning to code.

The school curriculum covers an element of coding with some subjects and pupils may be lucky to get a BBC Micro:bit or Raspberry Pi, however you don’t have to wait until school before learning any coding.

You don’t have to be young to start coding either. Using the same methods and tools anyone can learn to code.

The phrase “Learning to code” may strike fear and thoughts of hundreds of lines text and numbers, but it doesn’t need to. There are lots of websites available to help people start to code and present a fresh way of learning to code.

So where to start…….. If your reading this blog then you have access to a computing device. All you need to get started is a computing device with a web browser and access to the internet.

At this stage, its not worth getting hung up on the choices of the many different languages out there such as Python, Java, C etc, but concentrating on some fundamentals of coding.

Depending if you like Minecraft, Star Wars, Dr Who or Frozen, you can learn basic commands through gaming and interaction. These games teach you some basics of coding and commands by getting you to move a character on a screen to complete a number of tasks. Each of the games work in a similar way, using someones favorite characters to help them learn. These also help keep focus and attention.

The first code that you will learn is through blocks.

Minecraft – https://code.org/minecraft

Dr Who – http://www.bbc.co.uk/cbbc/games/doctor-who-game

Frozen – https://studio.code.org/s/frozen/stage/1/puzzle/1

Star Wars – https://code.org/starwars

Moana – http://partners.disney.com/hour-of-code

Once you have completed the tasks in blocks, you could then also try using a different language with some of the games such as Java if you wish. Its a great way of experiencing some of the differences in the languages.

 

 

The main program behind blocks is Scratch. To see more on the block programming method have a look at Scratch itself.

https://scratch.mit.edu/

At the scratch site there are learning tools and lessons to help you learn as well as access to the full programming language. The Scratch site also hosts a lot of other peoples programs which you can run/play and look at how they have constructed their code.

Scratch is a free visual programming language developed by the MIT(Massachusetts Institute of Technology) Media Lab.[1] Scratch is used by students, scholars, teachers,and parents to easily create animations, games, etc. It provides a stepping stone to the more advanced world of computer programming. It can also be used for a range of educational and entertainment constructionist purposes from math and science projects, including simulations and visualizations of experiments, recording lectures with animated presentations, to social sciences animated stories, and interactive art and music.[2] Viewing the existing projects available on the Scratch website, or modifying and testing any modification without saving it requires no online registration.

Source:https://en.wikipedia.org/wiki/Scratch_(programming_language)

Scratch allows users to use event-driven programming with multiple active objects called sprites.[1] Sprites can be drawn, as vector or bitmap graphics, from scratch in a simple editor that is part of Scratch, or can be imported from external sources, including webcams.

All you need now is to dedicate some time each week to learn to code.

PISince its launch the Raspberry PI Zero seems to be in high demand with its low price of under £5.00 for the base module. The official suppliers are still out of stock with no view as to when they may receive their next shipment. They fly out as soon as they come in

This makes the PI Zero Stock literally Zero!

The unofficial supply chain of place such as Ebay are now up as high as £42.00 with sellers caching in on what is supposed to be a cheap computing platform.

Hopefully the stock levels will come back to a level to stem/curb the high prices coming in.

But why so popular – this is mainly due to the cheap price of the computing module and has captured the imagination of hackers, developers and hobbyists.

There are a wide range of interesting projects appearing on the net such as:

Hackaday and Adafruit have joined up to create a new competition looking for the best Raspberry PI Zero project.

The platform is ideal for IoT development of small modules, sensors and other projects. The other forms of the Raspberry PI is already being used for IoT projects such as a Home Heating Control Device.

It will be interesting to see what comes out of the competition and the next innovation. One competition I shall be watching with interest.

 

 

Are you rethinking your Java Plugin’s

Oracle have recently announced via a blog post that they are going to deprecate the Java browser plug in JDK9 and remove it from future releases.

By late 2015, many browser vendors have either removed or announced timelines for the removal of standards based plugin support, eliminating the ability to embed Flash, Silverlight, Java and other plugin based technologies.

With modern browser vendors working to restrict and reduce plugin support in their products, developers of applications that rely on the Java browser plugin need to consider alternative options such as migrating from Java Applets (which rely on a browser plugin) to the plugin-free Java Web Start technology.

Oracle plans to deprecate the Java browser plugin in JDK 9. This technology will be removed from the Oracle JDK and JRE in a future Java SE release.

Early Access releases of JDK 9 are available for download and testing at http://jdk9.java.net. More background and information about different migration options can be found in this short whitepaper from Oracle.

Source: https://blogs.oracle.com/java-platform-group/entry/moving_to_a_plugin_free

JavaMost browsers are already removing plugin support or don’t support extensions any more. See links below:

Oracle are addressing this through their Java Web Start which downloads the relevant files to your computer if not present then caches them for later use.

Java Web Start is an application-deployment technology that gives you the power to launch full-featured applications with a single click from your Web browser. You can now download and launch applications, such as a complete spreadsheet program or an Internet chat client, without going through complicated installation procedures.

Java Web Start includes the security features of the Java platform, so the integrity of your data and files is never compromised. In addition, Java Web Start technology enables you to use the latest Java SE technology with any browser.

With Java Web Start, you launch applications simply by clicking on a Web page link. If the application is not present on your computer, Java Web Start automatically downloads all necessary files. It then caches the files on your computer so the application is always ready to be relaunched anytime you want—either from an icon on your desktop or from the browser link. And no matter which method you use to launch the application, the most current version of the application is always presented to you.

Source: http://docs.oracle.com/javase/8/docs/technotes/guides/javaws/

However this may not be plain sailing as pointed out in this blog post from Openmicroscopy

What does it mean for desktop developers/administrators?

To deploy Java Web Start, one first needs to get familiar with Deployment Rule Sets. Administrators can then create a list of known-safe applications and manage compatibility between different versions of Java on the system. Each browser will have their own set of dialogs and control mechanisms.

It is getting harder and harder to distribute Java Web Start applications for developers and/or administrators.

Its good to see that GitHub has now provided a toolbar to aid in formatting Markdown.

This will help some users from using HTML code format to a word processor GUI type experience. It should appeal to those who are starting out on their coding journey or want an easier life not having to remember if they have included all the <> and </> commands in their files.

Below is an example of a Markdown file that I did as part of a Data Science Coursera Course:  https://github.com/Cloudmage/ExData_Plotting1/blob/master/CodeBook.md
