Leaving the ivory tower Español | Deutsch | Français | Italiano | Português

I've been planning to leave academia for some time, but kept on putting it off. Unlike the U.S. where tenure is a thing pursued vigorously by the great and the good, here in the U.K. at least it has long gone to dust. But my job was as permanent as they get, and actually left me a lot of time to do a lot of other things outside it that interested me...

Looking out over the Pacific

However recently I took a look around and discovered that everything that was getting me up in the morning had nothing to do with my day job, and everything to do with what I was doing outside it. That just isn't any way to live. So, I've just pushed the big red switch. I now have a long rope and will be using it to leave the ivory tower real soon, my last day here at the University of Exeter is later this week, Thursday the 4th of April.

I was originally planning to take a couple of months off to look around, mainly because I'm in the fortunate position that I can do that, and such opportunities shouldn't be wasted. However some Tesla-driving individuals said "Yes!" and I've now working on something that's going to swallow my life for the next couple of months.

However, I'm not complaining, it's just the sort of getting out of bed project that I'm quitting academia to do in the first place. You'll be hearing more about it shortly, just as soon as I can talk about it...

In the short to medium term I'm planning on staying freelance, and doing consulting, contracting, writing or anything else that'll pay the bills and keep the wolves from the door. Although I'm not opposed to the idea of joining a (large) company, I've just spent thirteen years working for someone else, it'll be nice to work for myself for a while. Or at least be nearer the top of the tree, as you can generally see the rest of the forest much better from there. That said, it doesn't mean I'm not open to offers; they'd just have to be interesting offers.

So, while I've got a large number of things that might come off; I'm interested in work. Preferably work of substance, but beggars can't be choosers.

I've done a number of (some quite infamous) things with iOS, and have a lot of experience on the app side of things. I have done a number of things that are now generally being lumped into the "Big Data" camp. While I'm not a Hadoop and NoSQL guy, I've done some interesting work with machine learning and agent architectures, mostly to do with distributed sensor networks. I'm a hardware guy, or at least I'm an Arduino guy, and have done a number of other things to do with that increasingly ubiquitous hardware platform.

I like playing with mobile platforms, hardware, software, sensors, 3D printers and data visualisation. Or preferably all of the above at the same time, a good example of this is the work on the Data Sensing Lab I've been doing for O'Reilly.

Basically I'm an emerging technology guy. If it's new and a lot of people know nothing about it, I probably know something or am learning about it right now. Then I generally write a book about it and move on to the next emerging technology. I like being on the cutting edge. It's interesting out here. Oh yes, I also helped discover the most distant astronomical object yet found; a gamma-ray burster at a redshift of 8.2. However I'm not so sure that's a useful skill outside of the ivory tower.

In summary then; I write, I code, I speak and am always willing to offer advice on things I know about.

Update: It has just been pointed out to me that I foresaw my own exit from academia some seven or eight years ago, back when I was still having fun in my day job, "...so what happens when I stop having fun? I'll probably have to sit down and make enough license plates so I don't have to worry about that stuff again."

Distributed Network Data Español | Deutsch | Français | Italiano | Português

My latest book, my first not talking about iOS and writing code for the iPhone and iPad, just went to press. It's called Distributed Network Data and it's hardware hacking for Data Scientists. It's the book of the +Data Sensing Lab and arrives just in time for this year's +O'Reilly Strata in Santa Clara, which starts tomorrow.

This book is intended for data scientists who want to learn how to work with external hardware. It assumes some basic computing and programming knowledge, but no real expert knowledge is assumed. From there the book walks you through build your own distributed sensor network to collect, analyse, and visualise real-time data about our environment.

If you're a data scientist, or a visualisation person, interested in getting started with hardware and collecting your own data, this is the book for you. You can use the code AUTHD to get 40% off print books, 50% on ebooks and videos when you buy the book directly from O'Reilly.

The 3Doodler is a 3D printer, but it's a pen. This takes 3D printing and turns it on its head...

In fact the 3Doodler rejects quite a lot of what most people would consider necessary for it to be called a 3D printer. There is no three axis control, there is in fact no software, you can't download a design and print an object, it strips 3D printing back to basics.

What there is, what it allows you to do, is make things. This is the history of printing going in reverse, it's as if Gutenberg's press was invented first, and then somebody came along afterwards and invented the fountain pen.

While it looks simple they've obviously overcome some serious technological difficulties to get it working. One of the things that's hard to do on 3D printers, at least hard to do well, is unsupported structures.

As anyone that owns a 3D printer will tell you, the cooling time for the plastic as it leaves the print head is crucial to allow you to print unsupported structures. Too hot and it doesn't work, the structure sags and runs, too cold and it just plain doesn't work at all. From their videos they seem to have cracked the problem, building a free standing structure seems to be easy and well within the capabilities of the pen.

It also takes 3mm ABS and PLA as its “ink,” the same stuff used by most hobbyist 3D printers. I've got spools of this stuff hanging around my house which I use in my own printer. But unlike my printer, which cost just under a thousand dollars, the 3Doodler costs just $75.

It doesn't have the same capabilities, but that's the difference between a printing press and a pen. It has different capabilities, ones a "normal" 3D printer doesn't have. It's not a cheap alternative, it's a different thing entirely.

I'm currently watching the 3Doodler climb towards their first million dollars on Kickstarter, and I when I say their first million I mean that, they have over 30 days to go on their campaign which has today has gone viral and made them the best part of that million. This is the next Pebble. The next Kickstarter success story.

They've tapped into a previously untappable market; people that wanted a 3D printer but couldn't afford one, and people that see the obvious potential of a fountain pen over a printing press, for both art and engineering.

The guys behind the 3Doodler made $60,000 dollars while I wrote this post, my hat is off to them. Because it's not often someone comes up with an idea this good.

I'm going to be writing a series of posts on hardware startups for the Radar over the course of the next few months, and rest assured I'll come back to the 3Doodler. But not until  they can type faster than they can make money.

The black rectangle won't last as long as the beige box Español | Deutsch | Français | Italiano | Português

It looks like putting #Linux on #Microsoft's new #Surface  is going to be an up hill struggle. I was actually expecting that...

The era of the commodity beige box is coming to an end, and the days of the general purpose computer are almost over. Most people never needed or wanted a general purpose computer, and they're going to be happy with more limited devices optimised for a single, or a few, purposes. So long as those devices just work.

As a scientist I've benefited from being able to take mass produced PCs and be able to put them on desks very cheaply. The amount of compute power we've had access to as a result meant that money that would otherwise have been spent on expensive high end workstations could be spent elsewhere.

Those of us that need general purpose computing; designers, developers, scientists, are going to have to go out and buy increasingly expensive niche machines, effectively old-fashioned workstations. High end computing platforms that the general population just don't need on their desk or in their pocket.

The fact you can't install #Linux  on the new #Surface  is just the start of what is going to be an increasingly obvious trend. It's just a symptom. The things that are open and the things that are closed are changing. Time to wake up and realise that. Being able to install #Linux  on your PC isn't important any more.

I think a lot of the web and mobile people are making the same mistake today that Nokia made five years ago, Nokia was all about the hardware and wasn't watching the software hard enough...

Today people are all about the software and aren't watching the hardware hard enough. Today's mobile phone, the black rectangle with, at most, a single button is a transition device. Don't get too comfortable with it, and don't stop thinking about innovation. Because the black rectangle won't last as long as the beige box.

Predicting a Singularity Español | Deutsch | Français | Italiano | Português

I think a lot about the future, and because of that I've gained somewhat of a reputation for making good predictions. This is a characteristic I share with prophets, messiahs and other ne'er-do-wells. I'm not entirely sure what to think about that.

However one of the problems with making predictions about the future, the main problem, is that it's actually not that hard to predict what'll happen next year. Although for some reason this doesn't really seem to help many of the major analysts whose job it is to make such forecasts. Conversely it's also not that hard to make a prediction for the far future, as "…any sufficiently advanced technology is indistinguishable from magic."¹ Why is this a problem? Well if it's easy to make those predictions, making predictions in the sweet spot, both far enough ahead to be ahead to get you ahead of your competition, and close enough that you'll still be around to do something about it is actually almost impossible.

But how far in the future is the sweet spot? The strange thing is that this actually changes, a century ago it was twenty years, or even thirty, but twenty or thirty years ago it was just ten years. Today it's probably five, or less. The rate of technological progress is accelerating, and with it the amount of change we'll experience during our lives is also changing. The time it takes for new technologies to emerge, become mainstream, become dated and then obsolete is falling almost exponentially.

For someone like me, whose career more or less relies on being on, and being seen to be on, the bleeding edge, this is painfully evident. If I'm asked "Have you heard about…?" and I have to answer "No?" you'll generally see a look of pain cross my face, something sort of like constipation, don't worry, it's just my career flashing before my eyes...

At this point having angered both business analysts and science fiction writers I'm going to make a small admission, both professions have the right of it because "...the future is already here — it's just not very evenly distributed."²

While the pace of change has accelerated, it's hard to see how that can be sustained as the size of the install base of existing legacy technology widens. So far we seem to have sustained that pace of change by trickle down economics, the older technology spreads out, and newer technology is dropped in, eagerly seized by early adopters like myself willing to pay the premium, and experience the inevitable problems that come with all new technology, at least until the bugs are shaken out.

Despite that I'm forced to point out that if you extrapolate the current rate of technological progress the view that some sort of technological singularity must almost be inevitable is hard to argue against. Unless of course there is some sort of major catastrophe, something to set us back.

Major catastrophes that could knock us back aren't hard to spot: a global pandemic, climate change, ecological disaster, super volcanoes, mega-tsunami, overpopulation, asteroid impact, a nearby supernovae and of course worldwide thermonuclear war are all favourites. The threat of some of these seems to be fading, but some seem more likely today than ever. There are others, many others, too numerous and depressing to list here.

They're also wildcards, because sometimes the things that should set us back push us forward. It's certainly arguable that two major world wars, so close together, were a major causal factor in the acceleration of the pace of change that is part of our lives today.

Depending on the current news cycle I can swing violently; between a horribly over optimistic view of the future and the inevitability of the rise of trans-humanism, and a view bleak in pessimism, in the inevitability of the abandonment of technology and a slow slide towards narrowing horizons and the eventual extinction of the human race. Doomed as a species that turned its back on space and by having its world view limited to just that, a single world with all the disasters and catastrophes that can result.

Despite this, I'll continue to try and make predictions in the sweet spot, it's fun to be proved right, and sometimes even more fun to be proved wrong.

You don't have to be awesome all the time... Español | Deutsch | Français | Italiano | Português

In her post talking about the public-ness of mourning after the death of Aaron Swartz, Danah Boyd writes "...we’ve created communities connected around ideas and actions, relishing individualistic productivity for collective good. But we haven’t created openings for people to be weak and voice their struggles and demons."

Geek culture is, at least in theory, a meritocracy, and you are measured by your accomplishments. But that means the best of us, those whose work is held up as shining examples, suffer from Impostor Syndrome. Sometimes cripplingly so, even when they are accomplishing awesome things. Because awesome things sometimes look a lot less awesome from the inside, when you know the limitations, flaws and problems with what you've built and shared with the community.

But worse than that, it means when you have your moment of weakness (and we all do), and for a while cannot contribute, cannot accomplish the day-to-day awesomeness that qualifies you as a member of good standing of the community, things can look very bleak. Because we expect the most from those of us that deliver the most, and even the great and the good can fall sometimes, and need support.

We've built a culture where it's hard to acknowledge that you don't know something, because knowing things is intricately linked with the doing of awesome things — which in turn is linked to our stature with our peers.

For someone like me, whose career more or less relies on being on, and being seen to be on, the bleeding edge, this is painfully evident. If I'm asked "Have you heard about…?" and I have to answer "No?" you'll generally see a look of pain cross my face, something sort of like constipation, don't worry, it's just my career flashing before my eyes…

I have no solutions to offer, only the sure and certain knowledge, which I give freely to other geeks, that you are not alone. That the great and the good amongst us suffer as well. That it's okay to be weak and not know the answer to a question. That it's okay to rest and take from others for a while. We'll still be here when you get back, and we'll still remember how awesome you are. You don't have to live your life on Internet time.

Goodbye Aaron Español | Deutsch | Français | Italiano | Português

I heard this morning that Aaron Swartz has committed suicide. He was just twenty six. That's far too young by anyone's measure.

It's unclear how much the pressures of the unreasonably harsh federal prosecution for the JSTOR incident might have weighed on him, because it's been clear that he was depressed for some years. Like many of us that suffer from bouts of depression he had good weeks, and bad weeks. But the legal mess he was in can hardly have been a light weight to bear.

We've had several well known people in the community commit suicide over the last couple of years, and it's jarring. From the outside they look like the best of us, the brightest, sometimes with the most to lose. From the inside it can look much bleaker.

People in our community grew up geeks, many grew up friendless and carry that burden into adulthood. They have real trouble reaching out when they need help; to the friends they're not sure they really have, to the family they often regard as having not been there for them when they were at school. As a result the community is littered with people that suffer depression, that struggle every day with it, and with Impostor Syndrome. No matter how accomplished people look on the outside, and despite past records that should make those accomplishments as evident to them as it is to the rest of us, they suffer. Often in silence. 

I didn't know Aaron well, we had exchanged a few words on a couple of occasions, but I should have had a chance to fix that. He was twenty six and he was at the start of things, not the end.

If you feel like you can't go on, if you feel like it's too much to bear the weight of your life alone. Please, don't do this, please reach out to your friends, your family, to strangers if you must. If you can't face your friends with the news that you hate your life. Because there is always someone that's going to miss you. Always.

Goodbye Aaron.

The inevitability of smart dust Español | Deutsch | Français | Italiano | Português

This post was first published on the O'Reilly Radar.

I've put forward my opinion that desktop computing is dead on more than one occasion, and been soundly put in my place as a result almost every time. "Of course desktop computing isn't dead — look at the analogy you're drawing between the so called death of the mainframe and the death of the desktop. Mainframes aren't dead, there are still plenty of them around!"

Well, yes, that's arguable. But most people, everyday people, don't know that. It doesn't matter if the paradigm survives if it's not culturally acknowledged. Mainframe computing lives on, buried behind the scenes, backstage. As a platform it performs well, in its own niche. No doubt desktop computing is destined to live on, but similarly behind the scenes, and it's already fading into the background.

The desktop will increasingly belong to niche users. Developers need them, at least for now and for the foreseeable future. But despite the prevalent view in Silicon Valley, the world does not consist of developers. Designers need screen real estate, but buttons and the entire desktop paradigm are a hack; I can foresee the day when the computing designers use will not even vaguely resemble today's desktop machines.

For the rest of the world? Computing will almost inevitably diffuse out into our environment. Today's mobile devices are transition devices, artifacts of our stage of technology progress. They too will eventually fade into their own niche. Replacement technologies, or rather user interfaces, like Google's Project Glass are already on the horizon, and that's just the beginning.

People never wanted computers; they wanted what computers could do for them. Almost inevitably the amount computers can do for us on their own, behind our backs, is increasing. But to do that, they need data, and to get data they need sensors. So the diffusion of general purpose computing out into our environment is inevitable.

Everyday objects are already becoming smarter. But in 10 years' time, every piece of clothing you own, every piece of jewelry, and every thing you carry with you will be measuring, weighing and calculating. In 10 years, the world — your world — will be full of sensors.

The sensors you carry with you may well generate more data every second, both for you and about you, than previous generations did about themselves during the course of their entire lives. We will be surrounded by a cloud of data. While the phrase "data exhaust" has already entered the lexicon, we're still essentially at the banging-the-rocks-together stage. You haven't seen anything yet ...

The end point of this evolution is already clear: it's called smart dust. General purpose computing, sensors, and wireless networking, all bundled up in millimeter-scale sensor motes drifting in the air currents, flecks of computing power, settling on your skin, ingested, will be monitoring you inside and out, sensing and reporting — both for you and about you.

Almost inevitably the amount of data that this sort of technology will generate will vastly exceed anything that can be filtered, and distilled, into a remote database. The phrase "data exhaust" will no longer be a figure of speech; it'll be a literal statement. Your data will exist in a cloud, a halo of devices, tasked to provide you with sensor and computing support as you walk along, calculating constantly, consulting with each other, predicting, anticipating your needs. You'll be surrounded by a web of distributed sensors and computing.

Makes desktop computing look sort of dull, doesn't it?

The fifth horseman never gets invited to the good parties Español | Deutsch | Français | Italiano | Português

This article was originally posted on Google+.

Yesterday +MG Siegler argued on +TechCrunch that Samsung is the fifth horseman of technology, filling in for the ailing Microsoft, when the four horsemen: Amazon, Apple, Facebook and Google go riding.

I have to disagree with the underlying assumptions. We're at yet another tipping point in technology. A few years ago we moved from the beige box to the black rectangle, but the black rectangle won't be with us for as long as the beige box.

That black rectangle, the ubiquitous form factor of today's smart phone, is a transition device and it's going to disappear quickly as the speed of technological change is accelerating rapidly. Of the four horsemen only Google seems to be working on alternatives with +Project Glass. It's possible the others, including Samsung, have working hardware, but the successor to today's smart phone is going to be all about context and user interaction.

I've stood up in front of audiences before and argued that our smart phones have our lives on them, the next generation of mobile technology is going to stand between us and our lives and add context. It's hard to do that without a lot of information about the user.

It's also going to be a big leap for the horsemen to make. Despite getting into hardware recently Amazon is about selling content, Facebook has never done hardware and I don't think have this sort of paradigm shift in their corporate bones, Apple has, but without Steve Jobs I don't think they'll have the guts to kill the iPhone and innovate. Samsung, the fifth horsemen that never gets invited to the good parties, is a box shifter. They know hardware, but they don't know design, and they don't know anything about their end users. Their customers are other companies, like Amazon, not you and me, the eventual consumers.

So out of all of them Google  seems to be the only one positioned to move forward, and it'll be a big leap for them even so. The developer release of +Project Glass later this year is going to be crucial. If I had the money to lose making a wager, I'd wager that it'll be some startup you or I haven't heard of yet that makes the leap to the next ubiquitous form factor.

Either way, it's going to be an interesting year...

The rise of the personal space program Español | Deutsch | Français | Italiano | Português

This article was originally posted on Google+.

Just over a year ago now, the first ever project I backed on Kickstarter was Kicksat. A project to put a swarm of small nano-satellites in orbit. The size of a couple of postage stamps each satellite has solar cells, a radio transceiver, and a micro-controller along with memory and sensors.

Today in the mail my souvenir satellite arrived, it's just 3.5 cm square. It's an engineering prototype, presumably one that failed verification, and it doesn't have it's solar cells attached, but otherwise its just like the ones that'll be flown into orbit.

An engineering sample of a flight ready Sprite nano-satellite.

At it's heart is a +Texas Instruments  CC430F5137. It's a whole system on a chip based around an MSP430 CPU, a 16-bit RISC ulta-low power micro-controller, along with an onboard RF transceiver operating in the sub-1GHz bands, a real-time clock and an integrated temperature sensor.

As well as the big solder pads at the top of the board for the solar cell there are a number of unpopulated pads on the board, including space for some through hole components, so there is certainly room for more sensors to be added on the board itself, and the MSP430 has the capacity to handle them.  

However the satellite is going to be entirely reliant on the solar cell for power, there is no battery back up on the board, and the satellite will only be able to operate on the Sun-ward side of its orbit. That means power is the limiting factor. The CC4305137 has good brown-out reset capability, probably one of the reasons it was chosen, however you have to wonder how much more can be crammed onto the board and still reliably operate. 

While it's might not seem much beyond a shrunken down Sputnik at that point, the Kicksat is ground breaking. In just fifty-five years we've advance from the point where it takes the might of one of the world's only super powers to put something like this into orbit, to the point where several hundred of them can be put into orbit by a graduate student with some enthusiastic backers.

Despite the pessimism I often express at the way the space programme is going, this is something that gives me a lot of hope that we aren't going the wrong way. That we aren't starting a march towards the abandonment of technology and a slow fall towards an age of declining possibilities and narrowing horizons.

Kicksat, the CubeSat designed to carry hundreds of these small Sprite nano-satellites aboard, is now on track for launch in the autumn of 2013 onboard the CRS-3/ELaNa-5 mission. This will be the third Commercial Resupply Service (CRS) flight to deliver supplies to the International Space Station (ISS) aboard a +SpaceX Falcon 9 rocket. KickSat, along with 5 other CubeSats, will be hitching a ride as a secondary payload thanks to +NASA's ELaNa  program.
