The Digital Shift

old tvIn 1963, when I was born…

Television was delivered over the airwaves. In black and white. We had four channels to choose from and we had to get out of our seat to change them. And we hardly ever heard a swear word.

Radio was only available using an AM signal. In mono. If you didn’t like the song that was on, you could switch to the other station. If you wanted to listen to music on the go, you had a small transistor radio with a tinny speaker or a single earpiece. And if you wanted to hear “your show”, you had to listen while it was being broadcast.

Newspapers were printed on paper and printed every 24 hours. The time between a story happening and us finding out about it was often several days. Which stories made it into the newspaper was decided by an editor somewhere. The text on the page was made by rolling ink across the tops of slugs of lead in shape of letters, assembled to make sentences, and then pressing those inked letters against paper. The paper was then folded, cut, bundled onto trucks and delivered to your local newsagent where you had to go to buy it.

Photography required the use of film, a long strip of plastic covered in a silver emulsion. You could take either 12, 24 or 36 photos at a time. Once you’d taken all the photos that would fit on the roll (and only then), you had to send them away to be developed. This usually took about 2 weeks.

Moviemaking also required film. It was a continuous strip of 8mm wide plastic and required a dark room and a projector to view it. Each reel went for 3 minutes. They were expensive to process, and hardly anyone ever bothered to edit them. Having sound was an expensive luxury.

Music was stored on round black disks called records, which had long spiral grooves etched into them that mirrored the soundwaves that described the music. It was, quite literally, an analog of the waveform. Later, you could get audio cassettes that could hold either 60 or 90 minutes of music. You had to flip them over halfway through, usually in the middle of a song. Solving technical problems with cassettes required the use of a pencil. The audio quality, in hindsight, was awful.

oldphoneTelephone calls were made from home, sitting next to the phone. If it was a long distance call you had to think in three minute blocks of time. You only called long distance on special occasions like Christmas or birthdays, and you had an egg timer sitting next to the phone. Telephones were made for making telephone calls. That’s all.

It’s now 2013.

In those 50 years that have passed, most people would agree that some of these things have undergone a few changes, and those changes have occurred mostly because they went digital.

Television went digital. It is now far more likely to be delivered over a cable In full high definition colour and 3D, with 5.1 surround sound. If you don’t like what’s on, you can choose from hundreds of other channels. If you want to watch something else entirely, you can stream on demand via YouTube or some other web-based video service.  Oh, and there probably will be swearing. Lots of swearing.

Radio went digital. You now have dozens and dozens of high quality FM transmissions to choose from. You can take your listening mobile in your car, or go portable on your MP3 player or phone. You can timeshift your listening by storing your favourite radio shows as podcasts and listen whenever it’s convenient. Or listen to stuff that you find interesting that would never make it on the radio.  All for free.

News went digital. Multiple streams of news, based on your interests, can be delivered to you almost as it happens. You can choose your sources; global, local, hyperlocal. You can contribute to the stream if you choose. You can comment, argue, debate. You can participate. Twitter redefines what we mean by news, and can help start revolutions in the process. We can find out about anything, anytime, anywhere. For free.

Photography went digital. You can now take as many photos as you want, in massively high resolution. You can see them immediately after you take them. You don’t have to wait. You can enhance them, fix them, or delete them if you don’t want to keep them. You can share them instantly with anyone, anywhere in the world. Immediately. For free.

Moviemaking went digital. You can now shoot movies in ultra high definition. With sound. You can view them immediately, edit them in ways that only professional studios could once do, share them easily with your family and friends. You can send them to any device you like, to watch right away. For free.

Music went digital. The processes for creating, storing, distributing and sharing music are dramatically different. Using services like iTunes, Pandora or Spotify, you can listen to any music you like, whenever you like, however you like, on whatever device you like. It’s delivered in high quality stereo. It’s editable and remixable. You can swap and share music with others, anywhere in the world. For free.

Communication went digital. Telephones have morphed into mobile “devices” that can be carried anywhere, making you contactable wherever you are. Voice signals now travel the world over thin glass threads at the speed of light. VOIP software like Skype or Google Voice let you talk to anyone, anywhere, for as long as you like, with multiple people. With video too if you want it. For free.

And the best part of all? Because all of these things share the same digital heritage of zeros and ones, they can be easily mixed and mashed, and can live on the same clever device, bringing us true digital convergence.

So think about it. Think about just how much the rules have changed.  In a mere 50 years – barely a blink really – we have gone from a world where things that were hard to do have become easy, things that were time consuming to do have become instant, things that offered few options now come with seemingly unlimited choice, things that were expensive have become virtually free, things that were once scarce are now abundant.

Think about what that does to the world. What happens to economics when scarcity swaps places with abundance and expensive things become free? What happens to the human experience when time-consuming things become instant and difficult things become easy?  What happens to society when things that once required special training and special equipment are now within the reach of anyone who wants to do them?

In less than 50 years we have essentially shifted from an analog world to a digital world. The implications of that change have affected virtually every field you can think of. It’s difficult to imagine how an industry like banking or travel could possibly have ever functioned without the use of digital information and communication technologies. Like it or not, this digital genie is never going back into the bottle.

So, what are your survival strategies for a digital world?
What sorts of things do you do to feel at ease in a digital world?
What are the essential skills, mindsets and attitudes that one needs for a digital world?
What moral and ethical stances make sense in a digital world?
How do you become a productive, responsible citizen in a digital world?
How do you stay safe in a digital world?
How do you decide what is public and what is private in a digital world?
How much do you share in a digital world?
What defines appropriate in a digital world?

These are the sorts of questions we should be asking ourselves as we aim to be productive members of a society gone digital. Ironically, while some of these things require a serious rethink, many of the answers may simply be an evolution of those that applied in the analog world. The question is, which ones?

And once you figure it out, how do you help children figure it out? Because for them, this is the only world they’ve even known.

Shiny Object Syndrome

ChromebooksFor a while now I’ve been really keen to get my hands on one of the new Chromebooks but they have been as scarce as the proverbial rocking horse poop. I played with the original CR-48 units at the 2011 Sydney Google Teacher Academy, and although I thought they were a brilliant concept, troubles with the wifi at the time (at Google HQ of all places!) had me going back to my MacBook Pro sooner than I planned. The basic concept of a Chromebook is a computer where the operating system is basically just a browser (although I don’t think it’s really fair to refer to Chrome as “just a browser”.)

Still, by minimising the operating system to little more than a support system for the web browser, it really enables the web to emerge as the platform. With most of the data stored away from the machine – in the cloud – it means that users don’t have to worry about locally stored data. With the “software” on the machine really just being web services on cloud-based servers accessed via the browser, it means that your “software” is always up to date and always the latest version. If you lose the Chromebook or it gets damaged, you lose no data, since there was no data on it to begin with. Just grab another Chromebook, log in with the same Google account and you’re back to exactly where you were.

For schools in particular, it’s a brilliant concept. No software to install and maintain, no user data to store locally, nothing to back up, light and portable, easy to share… just log in and use it.

So for all of these reasons and others (Hey, I just like gadgets!) I was really keen to get my hands on one of the recently released Samsung units. The reviews have been very positive, although dealing with the lack of supply has been pretty frustrating. Lots of people want to buy them, but they have been really hard to get in the US and near impossible everywhere else.

In the leadup to the Sydney Google Summit I was hoping to get hold of one but it didn’t happen. I tried to buy one on Amazon but they refused to ship to Australia. I probably could have bought one on ebay, but for an arm and a leg. Fortunately, while at the Summit I had a chat with Suan Yeo, the head of education for Google in Asia Pacific and he mentioned that he might be able to organise me a loaner.

Well, long story short, I got an email yesterday letting me know that if I wanted to swing by the Sydney Google offices there was a shiny toy made of Chrome for me to play with for a month. Woohoo!  I dropped by after work and picked it up, and I’m now writing this blogpost on it.

Here’s my plan. For the next 30 days I plan to use ONLY the Chromebook for my own personal computing use, just to see how feasible it really is to live entirely in the cloud.  Of course, there are still things I need to do for my job at school that will require access to network drives and printers and so on, so I will have to keep using my Windows machine there. But I will have the Chromebook on my desk during the day and I intend to use it exclusively as my personal machine for the next month. I’ll blog about it here and let you know how it goes, what works for me, what doesn’t and try to give you an insight into what it’s like to live exclusively in nothing but a browser.

First impressions…

I really like it.  I love the size and weight for portability, although the smaller screen size is certainly making my eyes work harder than the larger 15 inch screen on my MacBook Pro or my iMac. But it’s certainly no worse than the 11 inch MacBook Air I have been using as my portable machine. The general build quality feels quite adequate… a little plasticky compared to an aluminium bodied Macbook, but then, so do most other computers. It’s certainly comparable to similar machines, and amazing when you consider it sells for about $250.

I’ve been pleasantly surprised by some of the additional functionality that I didn’t expect. Despite not having a “file system” as such, it does have a desktop, a downloads folder, and it can read and write USB and SD card drives. The access to Google Drive is pretty seamless, as you’d expect.  I don’t recall what the earlier Chromebooks did for storage prior to Drive, but having Drive certainly makes them quite usable. The keyboard is full size but has extra buttons that are specific to the Chromebook (and the keys are in lower case, which looks really odd at first.) There are lots of keyboard shortcuts that I want to learn to make it even more functional to use, and they can be accessed by pressing ctrl-alt-?.

Signing into the machine with my Google account immediately brought all my apps, themes and extensions across from my other machine, so within minutes I was working away as though I’d owned the machine forever. Very cool.

Battery life has been amazing. I took it off charge this morning, used it at work all morning, took notes in a meeting, showed it to quite a few people, spent a couple of hours browsing the web, have just been writing this post and it’s now nearly 4pm and it’s still going strong.  Even with the screen brightness turned way up, which is the way I like it, I think I would easily get a full days use from it.

The trackpad is quite good, and it has the same two-finger scroll and two-finger secondary click that I’m used to from the MacBook. I don’t much like trackpads at the best of times, and would always prefer to plug in a mouse (which I haven’t done yet) but the trackpad is about as good as it should be.

So, it’s looking good so far. If you’re interested in following my month with a Chromebook check back here again over the next few weeks and I’ll let you know how it’s going.

Google Teacher Academy in Sydney

At the recent Google Apps for Education Summit held at MLC School in Sydney, details for the next Google Teacher Academy were announced. Rather appropriately, the next GTA will be held in Sydney on May 7/8 at the Google Offices in Pyrmont.

Full details and a link to the application form can be found at http://www.google.com.au/edu/teachers/google-teacher-academy.html

It’s a great couple of days and although it can certainly be a bit of a brain dump and information overload, you’ll have the opportunity to network with other passionate and dedicated educators, meet with some of the local Sydney Google staff, become a part of the very active Google Certified Teacher community, and join in some fun social events as well.

The event is open to people from all over the world… at the last Sydney GTA in 2011 we had participants from the US, Guam, France, Russia and other places. People come from far and wide to attend the GTA. Of course, I happen to think it would be nice to grow the local GCT community even more, so come on you Aussies and Kiwis, get your applications in by February 28.

I’m looking forward to meeting lots of you there!
