One day to go!!

We hope you’re as excited as we are!

We’ve seen many new registrations role in over the past two days, so you may have missed some of our messages from the registration platform.

Here is some information that you’ll need as you’re starting to prepare for tomorrow:

1. Check out your travel route to the event. St. John’s Hoxton is at the junction of New North Rd and Pitfield St, a short walk from Old St or Hoxton tube stations, and close to the 271 and 394 bus routes. If you’re driving, the post code is N1 6NP, and you can book parking on the premises for £11 per day.

2. Check out your travel times. We’re opening up registration bright and early at 8:30(there’ll be coffee and tea, plus lots of great local caffs for a take-away), and the whole thing kicks off at 10:00. The Lightning Talks should be finished by around 8:30 or 9:00 if you’re catching a train back – but we hope that you’ll stay overnight with us at the venue! Saturday morning also kicks off at 10:00.

3. Pack your overnight gear. That’s right, you’re welcome to stay with us over night! There is lots of room on the grassy grounds for camping, or roll out your sleeping bag in a cozy corner of the main building (where there will also be a female-only space available). Don’t forget your toothbrush.

OTA09 t-shirt4. Pack you chargers, memory cards, laptop, hackable devices, prototyping kit, LEDs, Sugru, drones, nerd-cred t-shirts, emergency chocolate bars, stickers to give away… maybe pre-download a few handy libraries while you’re at it.

5. Bring your own lanyard and show us all of the cool events you’ve been to lately (while also showing us your name).

6. Check out the programme on Lanyrd and build your own schedule by selecting ‘Plan to Attend’ or ‘Track’. While you’re at it, let other folks know you’re going by marking yourself as ‘Attending’ .

7. Have a read through of this year’s Hackathon Challenges for some inspiration and ideas about what you might hack.

8. Toss around some ideas with others by joining the conversation on Slackline.

9. Have a quick read of our Hack Day Code of Conduct. We know it’s clear but it is very worth mentioning one more time – ALL are welcome at Over the Air!

10. Get some sleep tonight! …you might not tomorrow 🙂


See you soon!

CoderDojoWe are pleased to once again be collaborating with the CoderDojo London team, to offer a free coding event for 7 to 17 year olds on Saturday the 26th. If you are attending Over the Air, we invite you to register your 7 to 17 year-old (or niece or nephew) to take part in the CoderDojo workshop.

They will need to bring a laptop with them to take part, and all minors must be accompanied by a parent or guardian for the entire duration of the session. The event is completely free but numbers are limited so we do ask that you register and get a ticket in advance, including your own name, so that we can plan for the correct numbers.

CoderDojo is a worldwide movement of free, volunteer-led, community-based programming clubs for young people. Anyone aged seven to seventeen can visit a Dojo where they can learn to code, build a website, create an app or a game, and explore technology in an informal, creative, and social environment.

The CoderDojo movement believes that an understanding of programming languages is increasingly important in the modern world, that it’s both better and easier to learn these skills early, and that nobody should be denied the opportunity to do so.

Featured tracks at the event will include:

  • Swift Playground
  • Naturebytes
  • BBC micro:bits

A number of the CoderDojo workshop participants will be invited to do a “Show & Tell” of their work on Saturday afternoon after the Hack Day entrants have shown their hacks. It is entirely up to your child whether they would like to take part in this, but unfortunately we won’t have enough time available for all children to take part.

Building with Accessibility in Mind

A guest post from Gary Readfern-Gray, remedy  Accessibility Specialist & Developer at the RNIB (Royal National Institute of Blind People)

rnibNowadays it seems like almost everyone is using their mobile phone for a growing range of purposes. Developers know that it can be a real challenge to think about the needs of all their potential customers, salve  including those who may have problems using their apps due to some form of disability.

You may therefore be surprised to hear that blind and partially sighted people along with those of us with other disabilities are using smart phones in all areas of daily life. Screen readers that are gesture controlled are incorporated into all the major mobile platforms bringing a smooth flat touch screen to life.

With functionality like VoiceOver on Apple and TalkBack on Android, vialis 40mg where a synthetic voice gives you the information on what it shown on the screen can make apps useable even if when the user is unable to see the screen.

If properly coded, all items on the screen (including headings, buttons, text etc) will be read aloud so that the user can identify were they are in an app and what to do next.

Smart Phones are becoming more and more accessible, opening up a world of possibilities with apps that could make life a whole lot easier.  We hope that we can enthuse and inspire you to write code to to make apps accessible and help more of your customers have a thrilling user experience with your apps.

#TheOpenAgenda – Why the world needs an open future

By: Daniel Appelquist (@torgo), viagra 60mg Open Web Advocate, site  Telefonica Digital

At Telefónica, price order we recently launched something called #TheOpenAgenda ( – a cross-industry initiative  to ask what does open mean and why is it so important?

The concept of open first gained traction in the technology industry with the birth of the free software movement in the 1980s, which evolved into today’s hugely successful open source movement. Open source provides free access to software code in order for anyone to make changes and improvements to the final product.

This ability for huge networks of individuals to pool their collective expertise led to an unparalleled boom in technical and creative innovation.

Open, defined as ‘accessible to all, free from limitations, boundaries or restrictions’, has since been widely adopted across increasingly broad sectors of technology and the digital world.

Open access to what have become the basic building blocks of our society promises to provide incredible benefits to consumers, businesses and the public sector.

Governments realize this and are opening up the data they hold to third parties to enable the creation of services that will better serve their citizens. Businesses realize this and are opening up to their customers, giving them the ability to become true participants in the business rather than just sales targets.

The value of open is also being recognized in an increasing willingness by companies to collaborate and partner with third parties and even their rivals in order to better serve their customers. In fact, companies in all industries are opening dedicated open initiatives.  In July 2013, Rolls-Royce launched an open innovation program, joining the likes of Unilever, which launched its own in 2012.

The open philosophy is reaching into all areas of business. The European Commission in June 2013, for instance, in its Digital Agenda for Europe, called for better use of standards in procurement to stop businesses becoming locked in to ICT systems.

The World Wide Web, the backbone of today’s society and economy, was of course founded on a principle of openness that has resulted in the birth of some of the most innovative companies the world has ever seen.

TelefonicaDigitalSquareHighResTelefónica itself is also embracing open in various ways that are driving the open web, such as our support of Firefox OS, open data, including a partnership with the Open Data Institute, and open innovation, through initiatives such as our Wayra start-up incubator. The support that Telefónica shows for the Over the Air event itself is also about putting some energy back into the community to support open innovation.

However, we should be under no illusions of the challenges that remain ahead.  The open philosophy, despite the enormous benefits it offers all levels of society, is often fighting against a deeply engrained attitude of resistance to free access of information.

The growth of the open Web on mobile for instance, is being held back by a return to closed ecoystems and walled gardens. Consumers are being corralled into proprietary systems, only able to access certain content. Content bought through one service is not transferrable when consumers switch and choice is being dramatically curtailed.

We believe the value of open is worth fighting for. The concept is too important to be become merely a commodity, a truism that is devalued by those without a true commitment to the open philosophy.

#TheOpenAgenda is a cross-industry project collating the views of leading thinkers from across the open movement. It will dig deep into the meaning of open across three key areas: open web, open data and open innovation.

It will discover exactly how the value of open is being delivered in each area to benefit consumers, business, and society, discovering the challenges ahead and how they are being overcome.

The aim of #TheOpenAgenda is to catalyse global debate around the concept of open. Through a series of online and real world events, we will engage stakeholders across multiple industries to employ the very collaborative principles of the open movement to help define and spread the benefits of open.

As a worldwide society we need to debate the value and issues of open – it’s crucial to all our futures.

Join the debate on Twitter using #theopenagenda and @tefdigital – I’d love to hear your thoughts.
