Talking about IBM Watson (again)

As I mentioned in May, I was lucky to be able to go to Thinking Digital this year and talk about what we’re doing with Watson.

I’ve just noticed that they’ve made a video of my talk available. I haven’t dared watch it (does anyone like watching videos of themselves?), but I figured I should share it anyway!


Monkigras 2014: Sharing craft

After Monkigras 2013, I was really looking forward to Monkigras 2014. The great talks about developer culture and creating usable software, the amazing buzz and friendliness of the event, the wonderful lack of choice over which talks to go to (there’s just one track!!), and (of course) the catering:

coffee
cheese

The talks at Monkigras 2014

The talks were pretty much all great so I’m just going to mention the talks that were particularly relevant to me.

Rafe Colburn from Etsy talked about how to motivate developers to fix bugs (IBMers, read ‘defects’) when there’s a big backlog of bugs to fix. They’d tried many strategies, including bug rotation, but none worked. The answer, they found, was to ask their support team to help prioritise the bugs based on the problems that users actually cared about. That way, the developers fixing the bugs weren’t overwhelmed by the sheer numbers to choose from. Also, when they’d done a fix, the developers could feel that they’d made a difference to the user experience of the software.

While I’m not responsible for motivating developers to fix bugs, my job does involve persuading developers to write articles or sample code for WASdev.net. So I figure I could learn a few tricks.

A couple of talks that were directly applicable to me were Steve Pousty‘s talk on how to be a developer evangelist and Dawn Foster‘s on taking lessons on community from science fiction. The latter was a quick look through various science fiction themes and novels applied to developer communities, which was a neat idea though I wished I’d read more of the novels she cited. I was particularly interested in Steve’s talk because I’d seen him speak last year about how his PhD in Ecology had helped him understand communities as ecosystems in which there are sometimes surprising dependencies. This year, he ran through a checklist of attributes to look for when hiring a developer evangelist. Although I’m not strictly a developer evangelist, there’s enough overlap with my role to make me pay attention and check myself against each one.

One of the risks of TED Talk-style talks is that if you don’t quite match up to the ‘right answers’ espoused by the speakers, you could come away from the event feeling inadequate. The friendly atmosphere of Monkigras, and the fact that some speakers directly contradicted each other, meant that this was unlikely to happen.

It was still refreshing, however, to listen to Theo Schlossnagle basically telling people to do what they find works in their context. Companies are different and different things work for different companies. Similarly, developers are people and people learn in different ways so developers learn in different ways. He focused on how to tell stories about your own failures to help people learn and to save them from having to make the same mistakes.

Again, this was refreshing to hear because speakers often tell you how you should do something and how it worked for them. They skim over the things that went wrong and end up convincing you that if only you immediately start doing things their way, you’ll have instant success. Or that inadequacy just kicks in like when you read certain people’s Facebook statuses. Theo’s point was that it’s far more useful from a learning perspective to hear about the things that went wrong for them. Not in a morbid, defeatist way (that way lies only self-pity and fear) but as a story in which things go wrong but are righted by the end. I liked that.

Ana Nelson (geek conference buddy and friend) also talked about storytelling. Her point was more about telling the right story well so that people believe it rather than believing lies, which are often much more intuitive and fun to believe. She impressively wove together an argument built on various fields of research including Psychology, Philosophy, and Statistics. In a nutshell, the kind of simplistic headlines newspapers often publish are much more intuitive and attractive because they fit in with our existing beliefs more easily than the usually more complicated story behind the headlines.

The Gentle Author spoke just before lunch about his daily blog in which he documents stories from local people. I was lucky enough to win one of his signed books, which is beautiful and engrossing. Here it is with my swagbag:

After his popular talk last year, Phil Gilbert of IBM returned to give an update on how things are going with Design@IBM. Theo’s point about context of a company being important is so relevant when trying to change the culture of such a large company. He introduced a new card game that you can use to help teach people what it’s like to be a designer working within the constraints of a real software project. I heard a fair amount of interest from non-IBMers who were keen for a copy of the cards to be made available outside IBM.

On the UX theme, I loved Leisa Reichelt‘s talk about introducing user research to the development teams at GDS. While all areas of UX can struggle to get taken seriously, user research (eg interviewing participants and usability testing) is often overlooked because it doesn’t produce visual designs or code. Leisa’s talk was wonderfully practical in how she related her experiences at GDS of proving the worth of user research to the extent that the number of user researchers has greatly increased.

And lastly I must mention Project Andiamo, which was born at Monkigras 2013 after watching a talk about laser scanning and 3D printing old railway trains. The project aims to produce medical orthotics, like splints and braces, by laser scanning the patient’s body and then 3D printing the part. This not only makes the whole process much quicker and more comfortable, it is at a fraction of the cost of the way that orthotics are currently made.

If you can help in any way, take a look at their website and get in touch with them. Samiya and Naveed’s talk was an amazing example of how a well-constructed story can get a powerful message across to its listeners:

After Monkigras 2014, I’m now really looking forward to Monkigras 2015.


 

At ThingMonk 2013

I attended ThingMonk 2013 conference partly because IBM’s doing a load of work around the Internet of Things (IoT). I figured it would be useful to find out what’s happening in the world of IoT at the moment. Also, I knew that, as a *Monk production, the food would be amazing.

What is the Internet of Things?

If you’re reading this, you’re familiar with using devices to access information, communicate, buy things, and so on over the Internet. The Internet of Things, at a superficial level, is just taking the humans out of the process. So, for example, if your washing machine were connected to the Internet, it could automatically book a service engineer if it detects a fault.

I say ‘at a superficial level’ because there are obviously still issues relevant to humans in an automated process. It matters that the automatically-scheduled appointment is convenient for the householder. And it matters that the householder trusts that the machine really is faulty when it says it is and that it’s not the manufacturer just calling out a service engineer to make money.

This is how James Governor of RedMonk, who conceived and hosted ThingMonk 2013, explains IoT:

What is ThingMonk 2013?

ThingMonk 2013 was a fun two-day conference in London. On Monday was a hackday with spontaneous lightning talks and on Tuesday were the scheduled talks and the evening party. I wasn’t able to attend Monday’s hackday so you’ll have to read someone else’s write-up about that (you could try Josie Messa’s, for instance).

The talks

I bought my Arduino getting started kit (which I used for my Christmas lights energy project in 2010) from Tinker London so I was pleased to finally meet Tinker’s former-CEO, Alexandra Dechamps-Sonsino, at ThingMonk 2013. I’ve known her on Twitter for about 4 years but we’d never met in person. Alex is also founder of the Good Night Lamp, which I blogged about earlier this year. She talked at ThingMonk about “the past, present and future of the Internet of Things” from her position of being part of it.

I think it was probably Nick O’Leary who first introduced me to the Arduino, many moons ago over cups of tea at work. He spoke at ThingMonk about wiring the Internet of Things. This included a demo of his latest project, NodeRED, which he and IBM have recently open sourced on GitHub.

Sadly I missed the previous day when it seems Nick and colleagues, Dave C-J and Andy S-C, won over many of the hackday attendees to the view that IBM’s MQTT and NodeRED are the coolest things known to developerkind right now. So many people mentioned one or both of them throughout the day. One developer told me he didn’t know why he’d not tried MQTT 4 years ago. He also seemed interested in playing with NodeRED, just as soon as the shock that IBM produces cool things for developers had worn off.

Ian Skerrett from Eclipse talked about the role of Open Source in the Internet of Things. Eclipse has recently started the Paho project, which focuses on open source implementations of the standards and protocols used in IoT. The project includes IBM’s Really Small Message Broker and Roger Light’s Mosquitto.

Andy Piper talked about the role of signals in the IoT.

There were a couple of talks about people’s experiences of startups producing physical objects compared with producing software. Tom Taylor talked about setting up Newspaper Club, which is a site where you can put together and get printed your own newspaper run. His presentation included this slide:

ThingMonk 2013: Best. Slide. Ever.
Best. Slide. Ever.

Matt Webb talked about producing Little Printer, which is an internet-connected device that subscribes to various sources and prints them for you on a strip of paper like a shop receipt.

Patrick Bergel made the very good point in his talk that a lot of IoT projects, at the moment, are aimed at ‘non-problems’. While fun and useful for learning what we can do with IoT technologies, they don’t really address the needs of real people (ie people who aren’t “hackers, hipsters, or weirdos”). For instance, there are increasing numbers of older people who could benefit from things that address problems social isolation, dementia, blindness, and physical and cognitive impairments. His point was underscored throughout the day by examples of fun-but-not-entirely-useful-as-is projects, such as flying a drone with fruit. That’s not to say such projects are a waste of time in themselves but that we should get moving on projects that address real problems too.

The talk which chimed the most with me, though, was Claire Rowland‘s on the important user experience UX issues around IoT. She spoke about the importance of understanding how users (householders) make sense of automated things in their homes.

The book

I bought a copy of Adrian McEwan‘s Designing The Internet of Things book from Alex’s pop-up shop, (Works)shop. Adrian’s a regular at OggCamp and kindly agreed to sign my copy of his book for me.

The food

The food was, as expected, amazing. I’ve never had bacon and scrambled egg butties that melt in the mouth before. The steak and Guinness casserole for lunch was beyond words. The evening party was sustained with sushi and tasty curry.

Why am I still at IBM?

Ten years ago.

6 August 2003.

I was a recent University graduate, arriving at IBM’s R&D site in Hursley for the first time. I remember arriving in Reception.


Reception – the view that greeted me when I arrived

Ten years.

It was a Wednesday.

I’m still at the same company. I’m still at the same site. I still do the same drive to work, more or less.

For a *decade*.

How did that happen?

It was never The Plan. The Plan (as cynical as it sounds in hindsight) was that I’d stay for two or three years. I figured that would be long enough to get experience, and then I’d leave to work at a small nimble start-up which was where all the “cool” work was.

The Plan never happened. A few years passed, and then another few… I kept saying that I’d leave “later” and before I knew it a ten year milestone has kind of snuck up on me.

I think I’m more surprised than anyone. I’ve never been at any place this long. I was at Uni for five years. The longest I was at any school was four years.

It’s a serious commitment, and one I never realised that I had made. I’ve not even been married for as long as I’ve been with IBM.

So why? Why am I still here?

I live here.

It’s been varied

I’ve spent ten years working for the same company, but I’ve had several jobs in this time.

I’ve been a software developer. I’ve been a test engineer. I’ve been a service engineer, fixing problems with customer systems. I’ve worked as a consultant, advising clients about technology through presentations and running workshops. I’ve done services work building prototypes and first-of-a-kind pilot systems for clients.

I’ve written code to run on tiny in-car embedded systems and apps that ran on mobile phones. I’ve worked as a System z Mainframe developer. I’ve written front-end UI code, and I’ve written heavy-duty server jobs that took hours to run (even when they weren’t supposed to).


IBM Hursley

It’s still challenging

I’ve worked on middleware technology, getting some of the biggest computer systems in the world to communicate with each other, reliably, securely and at scale. I’ve used analytics to get insight from massive amounts of data. I’ve worked on large-scale fingerprint and voiceprint systems. I’ve used natural language processing to build systems that attempt to interpret unstructured text. I’ve used machine learning to create systems that can be trained to perform work.

I’m still learning new stuff and still regularly have to figure out how to do stuff that I have no idea how to at the start.


Some views of the grounds around the office

I get to do more than just a “day job”

I do random stuff outside the day job. I’ve helped organise week long schools events to teach kids about science and technology. I’ve mentored teams of University students on summer-long residential innovation projects. I’ve prepared and delivered training courses to school kids, school teachers and charity leaders. I’ve written an academic paper and presented it at a peer-reviewed research conference. And lots more.

I’m a developer, but that doesn’t mean I’ve spent ten years churning out code 40 hours a week. There’s always something new and different.


Hursley House – where I normally work when I have customers visiting

I work on stuff that matters

Tim O’Reilly has been talking for years about the importance of working on stuff that matters.

“Work on something that matters to you more than money”

If you’ve not heard any of his talks around this, I’d recommend having a look. There are lots of examples of his slides, talks, blog posts and interviews around.

I can’t do his message justice here, but I just want to say that he describes a big part of how I feel very well. I want to work on stuff that I can be proud of. Not just technically proud of, although that’s important too. But the pride of doing something that will make a difference.

Working for a massive company gives me chances to do that. I’ve worked on projects for governments, and police forces, and Universities. I’ve done work that I can be proud of.

For the last couple of years, I’ve been working on Watson. It’s a very cool collection of technologies, and watching the demo of it competing on a US game show has a geeky thrill that doesn’t get old. But that’s not the most exciting bit. Watson could be a turning point. This could change how we do computing. If you look at what we’re trying to do with Watson in medicine, we’re trying to transform how we deliver healthcare. This stuff matters. It’s exciting to be a part of.


These are the views that surround the site

I like the lifestyle

Hursley is a campus-style site. It’s miles from the nearest town, and surrounded by fields and farms. It’s quiet and has loads of green open space.

My commute is a ten minute drive through a village and fields.

I don’t have to wear a suit, and I don’t stand out coming to work in a hoodie and combat trousers. Flexitime has been the norm for most of my ten years, and I am free to plan a work day that suits me. When I need to be out of the office by 3pm to get the kids from school, I can.

My kids are at a school half-way between home and the office, so I can do the school run on the way to work. As the school is only five minutes from work, I often nip out to see them do something in an assembly, or have lunch with them.

This is a nice aspect of the school – that parents are welcome to join their kids for lunch, and have a school dinner with them and their friends in the school canteen. But still… it’s pretty cool, and if I didn’t work just up the road from them, I wouldn’t be able to do it.

Once a month, I bring them to work in the morning before school starts for a cooked breakfast in the Clubhouse with the rest of my team.

All of this and a lot more tiny aspects like it add up to a lifestyle that I like.

More train tickets
Some of my train tickets from the last few years

I get to see the world

I enjoy travelling. I love seeing new places.

But I’d hate a job where I lived out of a suitcase and never saw the kids.

I’ve managed to find a nice balance. I travel, but usually on short trips and not too often.

In 2006, I worked at IBM’s La Gaude site near Nice. In 2007, Singapore, Malaysia, Philippines and Paris. In 2008, I worked in Copenhagen, Paris and Hamburg. In 2009, I worked in Munich many times, and Rotterdam. In 2010, Stockholm. In 2011, Tel Aviv and Haifa in Israel, Austin in Texas, Paris and Berlin. Last year, I worked in Zurich and Littleton, Massachusetts.

This year, I’ve been in Rio de Janeiro and Littleton again, and it looks like I’ll be in Lisbon in December.

Plus working around the UK. It’s less glamorous, but it’s still interesting to go to new places. I’ve worked in loads of places, like Edinburgh, York, Swansea, Malvern, Warwick, Portsmouth, Cheshire, Northampton, Guildford… I occasionally have to work in London, although I tend to moan about it. And I spent a few months working in Farnborough. I think I moaned about that, too. :-)

Travelling is a great opportunity. I couldn’t afford to have been to all the places that IBM has sent me if I had to pay for it myself.

The officemy deskCarnage
My office today (left), compared with some of the other desks I’ve had around Hursley

The pay is amazing!

Hahahahaha… no.

See above.


Grace at my desk at a family fun day at work in 2008

Will I be here for another ten years?

I’m trying to explain why I’m happy and enjoying what I do. I’m not saying I couldn’t get exactly the same or better somewhere else. Because I don’t know. Other than a year I spent as an intern at Motorola I’ve never worked anywhere else. For all I know, the grass might be greener somewhere.

Will I still be here in another ten years? I dunno… I do worry if that’s unambitious. I wonder if I should try somewhere else. I wonder if only ever working for one company is giving me an institutionalised and insular view of the world.

I keep getting emails from LinkedIn about all the people I know who have new jobs. There are a bunch of people I used to work with at IBM who have not only left to work at other companies, but have since left those companies and gone on to something even newer. While I’m still here.

Am I destined to be one of those IBMers who works at Hursley forever? That’s a scary thought.

For now, I’m enjoying what I do, so that’s good enough for me.

Happy 10th anniversary to me.


Going Back to University



A couple of weeks ago I had the enormous pleasure of returning to Exeter University where I studied for my degree more years ago than seems possible.  Getting involved with the uni again has been something I've long since wanted to do in an attempt to give back something to the institution to which I owe so much having been there to get good qualifications and not least met my wife there too!  I think early on in a career it's not necessarily something I would have been particularly useful for since I was closer to the university than my working life in age, mentality and a bunch of other factors I'm sure.  However, getting a bit older makes me feel readier to provide something tangibly useful in terms of giving something back both to the university and to the current students.  I hope that having been there recently with work it's a relationship I can start to build up.

I should probably steer clear of saying exactly why we were there but there was a small team from work some of which I knew well such as @madieq and @andysc and one or two I hadn't come across before.  Our job was to work with some academic staff for a couple of days and so it was a bit of a departure from my normal work with corporate customers.  It's fantastic to see the university from the other side of the fence (i.e. not being a student) and hearing about some of the things going on there and seeing a university every bit as vibrant and ambitious as the one I left in 2000. Of course, there was the obligatory wining and dining in the evening which just went to make the experience all the more pleasurable.

I really hope to be able to talk a lot more about things we're doing with the university in the future.  Until then, I'm looking forward to going back a little more often and potentially imparting some words (of wisdom?) to some students too.

Monkigras 2013: Scaling craft

Monkigras goody bag
Monkigras goody bag

The work of William Morris, my GCSE history teacher said, was a bit of a moral dilemma. Morris was a British designer born during the Industrial Revolution. British (and then world) industry was moving rapidly towards mass production by replacing traditional, cottage-industry production processes with the more efficient, and therefore profitable, machines. One thing that suffered under this move to mass production was the focus on function and quantity over decoration and quality. Morris reacted against this by designing and producing decorations like wallpaper and textiles using the traditional craft techniques of skilled craftspeople. My history teacher’s point was that although Morris, a passionate socialist, was able to create high quality goods by using smaller-scale production methods, only wealthy people could afford to buy his designs; which was hardly equality in action. On the other hand, the skills of craftspeople were being retained, quality goods were being produced, and the craftspeople were getting paid for that quality of their work.

My pretty, handcrafted latte
My pretty, handcrafted latte

Monkigras 2013, in London last week, took on this theme of ‘scaling craft’ in the context of beer, coffee, and software. All parts of this trinity of software development can benefit hugely from a focus on quality over quantity. Before I went to Monkigras, I wasn’t really sure what to expect from a tech event advertised as having a lot of beer. It did have a lot of beer (and coffee) available but if you didn’t want it you could avoid it (several people I talked to said they didn’t usually drink beer). And no one seemed to get ridiculously drunk. And there were a lot of very cool talks.

The beer was also a fun analogy to apply to software development. Despite pubs in the UK closing hand over fist at the moment, microbreweries are on the rise. Microbrewing is about producing beer in small quantities on a commercial basis so that quality can be maintained whilst still viable as a business. One of the things we learnt from a brewer at Monkigras is that the taste of water varies according to where it comes from. Water is a major component of beer so if the taste of your water supply changes, the taste of your beer changes. To maintain the quality of the beer you brew, you must work within the natural resources available to you and not over-expand. Similarly, quality comes from skilled and knowledgeable people who need to be paid for their skill. If you take on cheaper staff and train them less so that you can make more profit, you will end up with a poorer quality product. You get the idea.

Handcrafting a wooden spoon.
Handcrafting a wooden spoon.

This principle applies to all areas of craft, whether it’s producing quality coffee, a quality wooden spoon, quality conference food, or organising a quality conference, you have to focus on quality and ensure that if you scale what you do so that it’s more readily available to more people, you don’t sacrifice quality at the same time. And, importantly, that you know when to stop. Bigger doesn’t necessarily mean better.

Software is misleadingly easy to produce. Unlike making physical objects, there is very little initial cost to producing software; you can make copies and then distribute them to customers over the Internet at very little cost. Initially, at least, it’s all in the skill of the craftspeople and their ability to identify their target users and market. If they can’t make what people will buy, they will go out of business very quickly. As software development companies get larger, the people who make the software inside the company become further removed from the selling of their software to their customers. So they become more focused on what they are close to, the technology but not who will use it.

Phil Gilbert on IBM Design Thinking
Phil Gilbert on IBM Design Thinking

Phil Gilbert, IBM’s new General Manager of Design, comes from a 30-year career in startups, most recently Lombardi, where design was core to their culture. IBM has a portfolio of 3000 software products so, when Lombardi was acquired by IBM, Phil set about simplifying the IBM Business Process Management portfolio of products, reducing 21 different products to just four and kicking off a cultural change to bring design and thinking about users to the centre of product development. Whilst praising IBM’s history of design and a recent server product design award, he also acknowledged at Monkigras: “We are rethinking everything at IBM. Our portfolio is a mess today and we need to get better”. Changing a culture like IBM’s isn’t easy but I’ve seen and experienced a big difference already. Phil’s challenge is to scale the high-quality user-focused design values of a startup to a century-old global corporation.

One of the things that struck me most at Monkigras, and appealed to me most as a social scientist, was the focus on the human side. Despite it being a developer conference, I remember seeing only one slide that contained code. The overriding theme was about people and culture, not technology; how to maintain quality by maintaining a culture that respects its craftspeople and how to retain both even if the organisation gets bigger, even if that naturally limits how much the organisation can grow. Personal analogy was also a big thing…

Cyndi Mitchell from Logspace talked about her family’s hog farm and working within the available resources. Shanley Kane from Basho used Dante’s spheres to describe best product management practices. Steve Citron-Pousty from RedHat use his background as an ecologist to manage communities and ‘developer ecosystems’ (don’t just call it an ecosystem; treat it like one). Diane Mueller from ActiveState talked about her 20%-time project to build a crowdsourced database of totem poles and the challenges of understanding what gets people to want to contribute to such projects. Elco Jacobs talked about his BrewPi project: automatically managing the temperature of his homebrewing fridge using a RaspberryPi based controller, and how he has open-sourced to build a community to kick start it as a potential small business. Rafe Colburn from Etsy more directly makes the link between craft and software engineering in his slides.

3D printer making a spoon

I don’t know much about William Morris so I don’t know which presentations he would have enjoyed or disagreed with. Morris was a preservationist and started the Society for the Protection of Ancient Buildings to ensure that old buildings get repaired and not restored to an arbitrary point in the past. So maybe he would have found laser-scanning and 3D printing interesting. Chris Thorpe is a model train geek and likes to hand-make his own models of real-life objects. He too is interested in alternatives to mass manufacturing and has started to look at how to make model kits. He uses a laser to scan the objects and a 3D printer to prototype the models. He can then send the model to a commercial company who can make it into kits for him to sell. He has recently used his laser-scanning technique to scan a rediscovered old Welsh railway engine to preserve it, virtually at least, in the state in which it was found.

I had a great time with lots of cool and fun people. Well done to @monkchips for scaling a conference to just the right level of intimacy and buzz. The last thing I saw before I left was the craftsman making a wooden spoon pitted in competition against the 3D printer making a plastic spoon.

You can find many of the slide presentations and more about the conference Lanyrd.

developerWorks Days Zurich 2012

This week I had a day out of the office to go to Zurich to talk at this years IBM developerWorks Days. I had 2 sessions back to back in the mobile stream, the first an introduction to Android Development and the second on MQTT.

The slots were only 35mins long (well 45mins, but we had to leave 5 mins on each end to let people move round) so there was a limit to how much detail I could go into. With this in mind I decided the best way to give people a introduction to Android Development in that amount of time was to quickly walk through writing reasonably simple application. The application had to be at least somewhat practical, but also very simple so after a little bit of thinking about I settled on an app to download the latest image from the web comic XKCD. There are a number apps on Google Play that already do this (and a lot better) but it does show a little Activity GUI design. I got through about 95% of the app live on stage and only had to copy & paste the details for the onPostExecute method to clear the progress dialog and update the image in the last minute to get it to the point I could run it in the emulator.

Here are the slides for this session

And here is the Eclipse project for the Application I created live on stage:
http://www.hardill.me.uk/XKCD-demo-android-app.zip

The MQTT pitch was a little easier to set up, there is loads of great content on MQTT.org to use as a source and of course I remembered to include the section on the MQTT enabled mouse traps and twittering ferries from Andy Stanford-Clark.

Here are the slides for the MQTT session:

For the Demo I used the Javascript d3 topic tree viewer I blogged about last week and my Raspberry Pi running a Mosquitto broker and a little script to publish the core temperature, load and uptime values. The broker was also bridged to my home broker to show the feed from my weather centre and some other sensors.

Recent hacktivity

This time of year seems to be hacking season and over the last few days I’ve been along to two hackdays!

Friday was IBM’s internal Social Business Hackday. There was some MQTT hacking, a z/OS hack, hacks with Lotus Connections, hacks that could be the future of Lotus Connections, and I was attempting to hack a work around for a Jazz work item. And that was just at the Hursley local event! We were able to link up with a few other labs, but over two days there were IBMers hacking around the globe. There are going to be a lot of amazing projects to choose from when it comes to voting.

(There are a few more photos from HackDay X, and previous hackdays, on the IBM hackday group on flickr.)

For round two, today was the soutHACKton hack day. By the time I arrived the soldering and drilling had already begun!! Unfortunately I wasn’t able to stay long so I’m hoping there’ll me more of these in the future. I did just about have time to try out an idea I had to hack an old doorbell to sense people using the door knocker. A while ago I had accidentally created a touch sensor with a 555 timer while attempting to build another circuit. So my cunning plan was to deliberately create a 555 touch switch and connect it to the bolt on the inside of the front door. Unfortunately the best I could manage today was a two wire touch sensor, which isn’t going to work. At least not without leaving a wire hanging out of the letter box with some instructions attached! Unless someone who knows more about electronics can suggest a plan B, I may just resort to a boring doorbell button instead!!


Conversational Internet

tl;dr

We’ve built a prototype to show how we could interact with the Internet using a command-driven approach.

  • A screen reader, but one that uses machine learning and natural language processing, in order to better understand both what the user wants to do, and what the web page says.
  • One that can offer a conversational interface instead of just reading out everything on the page.

It’s a proof-of-concept, but it’s an exciting idea with a lot of potential and we’ve got a demo that shows it in action.

The problem : screen readers today

I’ve written about this before but here is a recap.

Visually impaired people can interact with the web using screen readers. These read out every element on a page.

The user has to make a mental model of the structure of the page as it’s read out, and keep this in their head as they arrow-key around the page.

For example, on a news site’s front page, once the screen reader has read out the page, you have to remember if the story you want is the fifth or sixth story in the list so you can tab the right number of times to get to it.

Imagine an automated telephone menu:
“for blah-blah-blah, press 1, for blather-blather-blather, press 2, for something-or-other, press 3 … for something-else-vague, press 9 …”

Imagine this menu was so long it took 15 minutes or more to read.

Imagine none of the options are an exact match for what you want. But by the time you get to the end, you can’t remember whether the closest match was the third or fourth, or fiftieth option.

The vision : a Conversational Internet

Software could be smarter.

If it understood more about the web page, it could describe it at a higher, task-oriented level. It could read out the relevant bits, instead of everything.

If it understood more about what the user wants to do, the user could just say that, instead of working out the manual navigation steps themselves.

The vision is software that can interpret web pages and offer a conversational interface to web browsing.

Failing to Invent

We IBM employees are encouraged, indeed incented, to be innovative and to invent.  This is particularly poignant for people like myself working on the leading edge of the latest technologies.  I work in IBM emerging technologies which is all about taking the latest available technology to our customers.  We do this in a number of different ways but that's a blog post in itself.  Innovation is often confused for or used interchangeably with invention but they are different, invention for IBM means patents, patenting and the patent process.  That is, if I come up with something inventive I'm very much encouraged to protect that idea using patents and there are processes and help available to allow me to do that.


This comic strip really sums up what can often happen when you investigate protecting one of your ideas with a patent.  It struck me recently while out to dinner with friends that there's nothing wrong with failing to invent as the cartoon above says Leibniz did.  It's the innovation that's important here and unlucky for Leibniz that he wasn't seen to be inventing.  It can be quite difficult to think of something sufficiently new that it is patent-worthy and this often happens to me and those I work with while trying to protect our own ideas.

The example I was drawing upon on this occasion was an idea I was discussing at work with some colleagues about a certain usage of your mobile phone [I'm being intentionally vague here].  After thinking it all through we came to the realisation that while the idea was good and the solution innovative, all the technology was already known available and assembled in the way we were proposing, but used somewhere completely different.

So, failing to invent is no bad thing.  We tried and on this particular occasion decided we could innovate but not invent.  Next time things could be the other way around but according to these definitions we shouldn't be afraid to innovate at the price of invention anyway.
