The Cloud and the power cut

Monday evening was eventful to say the least; there I was happily watching a movie when the lights start to flicker, �oh� I thought to myself �a small power surge�.

The latter was true, the former distinctly not.

I�ve got an energy monitor that displays your current (badum tish) energy consumption, my normal evening power draw is circa 200-300 watts, when the surge hit it spiked to well over 1.4kw, it continued to spike in this manner for over 20 minutes. Even though all my electronic equipment is on surge protectors, I still ran to the circuit breaker to kill the power and then proceeded outside to see how it was affecting the rest of the street. The power surge eventually changed to an all out power cut and with that Honiton road was cast back to the literal dark ages. So grabbing some candles, I wondered round the house checking things out to make sure nothing was on fire, I then I smelled oh so familiar smell of burnt electrical wires and equipment. However with no power I couldn�t check to see if anything was broken, so I went to bed.

On waking the next morning I hustled downstairs and flipped the circuit breaker back on and nothing happened, no lights, nothing.

There was no power, I was cut off.

Now alongside the usual inconveniences of no kettle, hot water or being unable to cook food, I had no internet.

Big deal right? Wrong

Humans are creatures of habit as am I, before walking to work my routine is this Shower, get dressed and then Whilst making and eating breakfast (via laptop or iPod touch):

* Review twitter feeds and respond
* Read/write personal and work email s
* Check news, games and other websites
* Download podcasts & other content for the day
* View e-learning blogs for new content
* Check up on current Chess games

So by the time I walk to work I�m:

* Fully informed of current happenings in the world (useful for generating student polls),
* Have a reasonable idea of what awaits me at my desk (ensures I can hit the ground running)
* Have responded to any mission critical emails (Quality of service is important)
* Already musing about blog posts based on websites I visited that morning

In short I am a more effective employee with the internet at my disposal; I can respond to things quickly, ensuring that if something has gone wrong, by the time I arrive at work, I already know about it and can get on with sorting out.

But not on Tuesday morning (I don�t have an iPhone as of yet, so I had no external internet connection).

I then realised that my entire online life is based in the Cloud: Google apps, Gmail, Flkr, Twitter, Facebook etc. Nothing resides on my local machine, all the data and content is stored on some data centre and processed on a web server. My machine, be it laptop, pc or iPod only presents that data to me, nothing more. Of course I have some applications installed on my netbook but it is no where near the amount it used to be. If you think about it, you can pretty much do everything you would traditionally use a locally installed application online.

Word processing, Calendars, Spreadsheets are well served by Google apps, photo editing by Flkr, you don�t even have to have a printer in your house as you can use an online printing service that delivers direct to your door.

The only application you need to facilitate this is a web browser, nothing more.

Cloud computing is the future (although one could argue that it�s actually a return to the Mainframe and Dumb terminal relationship from the 1980�s), the device is becoming almost an irrelevance, merely a point of access that enables you to connect to your application and services held on the internet.

The cloud is the future; it�s the next logical step in the evolution of both the PC and the internet, but my experience on Tuesday morning leads me to think it can never replace traditional application access methods until internet access is universal.


New mobile platform arrives: Android

New mobile platform arrives: Android


By Jonathan Nalder of www.mLearnxyz.net

As most geeks would know, the Google-developed mobile OS known as Android had its public unveiling last week. While only available on one handset in the US at the moment, its open-source nature and backing from Google mean that it is destined to become a major new mobile platform alongside the existing Palm OS, Windows Mobile, RIM Blackberry, and iPhone OSX.

We�re not interested in the competition between these OS�s here, but in what new features Android brings to the use of mobile devices for learning. In this case, what Android brings is an acceleration of the mobile access to cloud computing that iPhone OSX began 18 months ago. Because Google itself has no interest in desktop computers, Android devices currently link in directly with online services rather than syncing with a home computer as every other mobile OS has always done.

This means that files, music, video etc are all either accessed online, downloaded directly from the net, or streamed to the handset. What does this mean for education? Well, perhaps its another sign that our many labs stocked with desktop PCs are becoming less and less relevant. Perhaps forward thinking education departments need to start planning a cloud-computing based model for getting out content and services to its students. There�s a few interesting years ahead!

To read more on the Android launch (and a whole heap of interesting, though not-education focused comments) read the engadget article HERE.




Cloud Computing and mobility Part 2.

Cloud Computing and mobility Part 2.


In part one we looked at how computing may just become a service utility in the same sense as electricity or water, and be accessible anywhere via wireless technologies.

Not accessible on a desktop PC you can�t lug anywhere. And available to devices that don�t have the processing power of decent laptops. But is this what we see happening around us?

There are at least two ways in which I believe you can see the beginnings of this happening - all of them outside the corporate, big server IT industry where cloud computing is usually talked about due to its potential to reduce the cost of running in-house IT departments.

The first is the availability of devices designed for this whole new category - a class that has only appeared in the last 18 months. Sometimes known as MID�s (Mobile Internet Devices), there are now major examples being sold by none other than Nokia, Sony and Apple. Certainly the iPhone and iPod Touch you�ve heard of, devices which boasts desktop-class browsing abilities as a major selling point.

The Nokia n810 tablet, though larger with its button keyboard and bigger screen, is still portable and configured primarily to access the internet. Likewise the smaller (and yet to prove itself) Sony Mylo resembles a PSP, but is built for messaging and VOIP rather than gaming.

The recent CES tech conference saw a plethora of other such devices from LG, Intel and Asus unveiled as well. Apart from the iPhone, none of the above contain phone functionality, but instead assume that easy access to the web is the new killer app.

Alongside this new found rush to supply consumers with �always-on� wireless devices capable of accessing the internet as �cloud�, comes a push now to have the experience enhanced by having the �heavy-lifting� of processing web data conducted by remote servers so as to enhance the mobile experience.

Introduced as a beta just recently, the Skyfire browser is an example of just this, supplying to mobile devices only an easily processed image file of any web page, thus making zooming and panning of content almost simultaneous. Available for windows mobile devices, it significantly lowers load times, all thanks to work being done �off-device�, the very model that cloud computing allows, albeit in a mobile access focused way.

This kind of service combined with Google Docs (and similar online �Office�-like suites) offering of free online use of productivity and business software, means that the ability to leave behind expensive and over powerful computers for sleek and accessible devices is becoming a possibility for many.

So will these trends impact mobile learning? Well, there�s dozens of new mobile devices becoming available, check. There�s access to the total of human gathered information and online software such as Word processors, Photoshop and video editing, check. There�s much greater interactive communication than just the txting, non-connected programs or basic web pages that many mobile learning projects have relied on so far, check. That seems like a winner.

Just watch and wait for them to be banned but still turn up at a school near you!







Cloud Computing: money and mobilty

Cloud Computing: money and mobilty

So what does mobile learning have to do with �cloud computing�? And just what is �cloud computing�?

Anyone who has been into tech for even 10 years will remember the big step it was to buy that first PC. Mine was via my parents in 1988 - the screen was CGA with wait for it - 3 colours! It cost over $2500 at the time. So did our next PC - a 386. So did the next, a Pentium IV. My latest machine, a Macbook Pro also cost just over this same $2500 line. What�s with that?

Doing the sums (and adding in a 2004 iBook - cheap at $1800) shows that just on PC hardware, thats more than $12000 - admittedly this has been over nearly 20 years. But something has been happening that might just end this cycle for ever. More on that shortly.

But first, just imagine I wasn�t just one guy, but a large organisation that needed 100 computers, like my school. Multiply the average PC costs by that many with a replacement every 3-4 years and the costs really start to add up. And we haven�t even added software and printers, routers etc. Now imagine that computing power and the software it runs could be available not from your own expensive and energy sucking tower, but from the air.

From the air you say? Well, �wirelessly� might be a better way of putting it - because its the development of the wireless internet that is making this rather fanciful sounding idea a very real possibility as the tech industry goes forward. Its starting in small ways, from two different angles, but could soon just rise up and overturn the accepted computing model we have always lived with.

The first angle its coming from has nothing to do with mobile technology, but I�ll detail it briefly in this mLearning blog just for context. It stems very much from the money side of things we�ve already discussed. Keeping up to date with computing power is expensive! Not to mention the waste the industry generates (National Geographic article). So now that large amounts of networking and productivity software via the Web 2.0 have arrived, a machine capable of running a good browser is all that many people, including large business looking to save on hardware costs, may need.

With Yahoo!, Google, Amazon, .Mac etc online storage options reaching the many gigabytes now, many users may not even need much more now than a cheap usb drive and internet connection - all the rest is supplied as a service. Cloud computing then (also called utility computing) foresees that supplying this service will eventually look much like the other utility service providers we take for granted - such as power, electricity and water. Instead of $2500+ every few years, you�ll just have a bundled monthly fee.

The one problem with this model is that its only as good as where you can access it. 3G, wi-fi and wimax technologies however mean that staying in contact with ones online files and software can now be deployed anywhere. This is where mobile devices come in. One doesn�t have to lug a PC tower or even laptop around to still be able to perform desktop-class tasks - even Photoshop is being brought online by Adobe soon.

The next part of this article will examine just which mobile devices are leading this change, and what it means for mobile learning... until then, go here for further reading:
