Heading Home

44399729291_4288818c5b_z.jpg

We were up bright and early and on the road home by 8:00. The whole event was fantastic from start to finish. They say the next one will be in 2020. I’ll be there.

There is also talk of “electromagnetic pulse” events being organised in the gap between the “fields” events. It would be great to set up one of these in the Hull area.

Anyway, time to head for home and then to get the Air Quality sensor working with the badge…..

Day 3 of Electromagnetic Fields

Achievement Unlocked: Shower Ninja Level now at Master. Take a large waterproof bag for clean clothes and dry towel on the way in and dirty clothes and damp towel on the way out. Leave boots outside the shower cubicle, facing outwards so I can just step into them on the way out. I'm really getting the hang of this camping lark. Of course, it’s not rained at any point…..

Having settled into something of a routine the realisation is dawning that this won't go on forever and today is in fact the last day. Wah. I resolve to go to lots of sessions and get the badge air quality sensor working. 

After a great session on LoRa networking, and another on the scary way that you can hack into car keys, I went to some that were all about how the event itself. First up was a session on the making of the emf badge. It turns out that making a complete mobile phone device is actually quite tricky. Kudos that they actually managed to make it work. The next session was about power, amongst other things.

44370398612_d4707c7f98_z.jpg

This is the power distribution to the tents in our area of the camp. There were a bunch of “Tardis” booths that contained nothing but distribution boards and, I suppose, a whole bunch of fuses and whatnot. These were connected to a backbone that was powered by a bunch of great big generators spread over the camp.

After the talks and another abortive attempt to get my badge to work with the Air Quality sensor, we went for a wander into the “Null Sector”. This was a seemingly haphazard collection of shipping containers that held, well, interesting stuff. The best time to see it is at night - of which more later - but there were quite a few things to take a look at, including a container from MSRaynsford that contained a kind of steam punk workshop with a laser cutter and some lovely things for sale. I ended up with a useless box (which I’ve always wanted) and a wifi controlled StrandBeest. Of which more later.

After some more coding we headed for the closing ceremony. Rather sad. There was enough content for several weeks I reckon, I wish there had been more of me to go to all the things that I know I missed out on.

The good news was that we still had the evening to enjoy, including some electric car racing that was great fun to watch. I was also able to practice my panning technique as the cars whizzed past.

 I have no idea why there is a Christmas tree on the back…

As the night came down we ventured back into “Null Sector”. They had buttons you could press to send out great big gas flares, art installations, an RFID powered treasure hunt and a powerful laser light show. I did the best with my little camera, but the shots don’t really do the setup justice.

Then it was time for bed for the last night under canvas.

Day 2 of Electromagnetic Fields - Starting with Furby Hacking

 Good morning...

Good morning...

Shower Ninja Level Zero: Stand fully clothed in a shower booth and press the water button "just to see if it works". Then wonder why all the clothes you're wearing are now soaking wet. And have nothing to put wet clothes into. Oh well; the good news is that the shower was clean and the water was nice and warm. 

After breakfast it was time for some more sessions, starting with "Attacking Websites for Educational Purposes Only". The exploit that was explained was specific only to an elderly version of the PHPBB bulletin system that was released for a short time a while back, but the talk did bring home how vulnerable a site can be.

Then it was time to attack something a bit more cuddly, with a fantastic session on Furby hacking. From modest beginnings, intercepting Bluetooth messages containing firmware updates, the speaker ended up showing how to take complete control of the device, downloading sound and graphics into the hapless cuddly toy. It was so impressive that, not surprisingly, I've gone and bought a Furby device to play with. Such are the perils of connected sessions and Amazon's Buy it Now button. 

Next up was a really good talk on podcasting. I've never podcasted, despite apparently having "The perfect face for radio". However, after this talk, that set out why you would do it and why it is such a good idea, I'm strongly tempted to give it a go. 

 Building the badge al-fresco

Building the badge al-fresco

By now the emf badge had been released and it was back to the tent for a bit of assembly and testing.  I had a plan to connect an Air Quality sensor to the badge for no particular reason, and in an uncharacteristic piece of forward planning I'd actually 3D printed a case for the badge and attached a sensor and a rechargeable battery to it. Now all I had to do was connect up the wiring and write the code. This meant that session attendance had to take a bit of a back seat, although I did manage to catch part of an awesome session about converting photographs to poetry and another which went into scary levels of detail about how easy it is to hack RFID car keys. 

 It turned out that the bar was a good place to set up base camp and start developing

It turned out that the bar was a good place to set up base camp and start developing

After gatecrashing an Arduino session and hijacking a soldering iron for a few minutes I got the cabling wired up to connect the sensor to the badge and then my software worked first time. 

I always get nervous when that happens. My theory, which has been validated many times, is that any given project requires a "pound of flesh" of effort, and if it seems to be going easily that's because there's something nasty lurking round the corner. It turns out that my nervousness was well founded. Although I could get values from the sensor and display them, when I tried to turn the program into an application to publish in the app store for the badge it all went horribly wrong. I was sure it was something stupid that I'd done, but it was very hard to work out what. So, after a while I gave up and went for a wander down to the Hackaday tent where they were showing off hacks. There was a chap there with an amazing barrel organ made using laser cut panels. I also got to have a really good chat with the man behind the RC2014 project

After tea (pizzas this time) we headed for a special showing of Hackers, a deeply silly movie from 1995 that was one of the first on-screen portrayals of hacking. It was great fun and lovely to be part of a huge audience that shouted "Hack the Planet" at every opportunity. The presentation was followed by a question and answer session with the director of the film who gamely entered into the spirit of the thing, even down to judging the best hacker costume. Style tip: the more LEDS the better....

 A message for our times. 

A message for our times. 

After that we took some pictures of the fun and games going on in the Null Sector, and took a walk around the camp. There are various "villages" set out for particular interest groups. You could spend your entire time at the event just going round and seeing what they are doing.

Day 1 of Electromagnetic Fields

I’ve not done any camping for over thirty years. After my previous experiences with horizontal rain, sleeping bags frozen solid and forgetting the tin opener, I reckoned it would take something rather special to get me under canvas again.

 Home for the next three days...

Home for the next three days...

Turns out that EMF is something special. Electromagnetic Fields is a techie festival in a field. And it is awesome. There are technical tracks, there are crafting tracks, there are things that have been done “just because we were told they were impossible”. You have to stay the night in a tent, but it turns out that in good weather and with working toilets and showers, camping is actually quite fun. Particularly if you have mains power in your tent.

 They had these "Tardis" devices all over camp supplying power...

They had these "Tardis" devices all over camp supplying power...

We arrived on site bright and early and picked a spot that looked sensible. Pro tip number one: Lay your power cable from the supply before you pitch your tent, otherwise you’ll find that your wire is six feet too short and have to move everything. However, with that hiccup out of the way, and having made the decision that the fact our tent looked like a “lean to” owing to some curious asymmetry in its inner workings was not going to significantly impact on its integrity, we established base camp and had a look around.

It was around two minutes before I heard someone say to me “You’re Rob Miles aren’t you”. Turns out that I am, and that the techie world has a good quotient of Hull University Computer Science graduates you are out there doing good things and remember the tall bloke who talked a lot about C#. Rather more surprisingly was that the second person to say this, thirty seconds later, was also called “Rob Miles” and was giving a talk in the afternoon. Which of course I was going to attend. I just hoped he’d maintain the integrity of the brand.

The camp is huge, with three large stages for talks, four hardware labs for, well, hardware, and a bunch of other places to go and do stuff. There are themed areas around the site, with different makerspaces and interest groups all over the place.

 The best instructions you can get at the start of any event

The best instructions you can get at the start of any event

The first session was the opening one, which brought home the complexity and difficulty of creating a very well-connected village in the middle of a field. Everybody in the emf organisation does it for the hell of it, and it seemed like this year the setup had been more hellish that usual, with failing tent suppliers, hillsides and all manner of other things turning up to cause hassle. Not that we’ve noticed much not working; the only real disappointment being that the badge; a very interesting piece of technology that we all get to play with, is not ready just yet.

Anyhoo, after the opening talk the session tracks started. The great thing about emf is that at any given time there are two or three sessions that look really interesting. The bad thing about emf is that at any given time there are two or three sessions that look really interesting, and you can only go to one.

After a brief look at the Air Quality Sensor workshop being run by Southampton University (and someone else going “You’re Rob Miles aren’t you”) we caught a lecture on a tele-presence robot by Libby Miller. It was a great talk, emphasising the ease with which you can create a something that works well for remote interaction and guaranteeing a peak in sales of a certain Ikea lamp which was used as the basis of the device. I’d love to build one. The instructions are here if you fancy making one to: https://github.com/libbymiller/libbybot_eleven

After that, a change of pace with a session with the fascinating title “101 Hacks for Late Soviet Water Towers”. The presenter of this session certainly leads an interesting life, which involves buying a water tower in Latvia by mistake for five euros and then finding out that you can save your five pound membership fee of the British Water Tower Appreciation Society (http://bwtas.blogspot.com/) if you actually own a water tower.  Which almost makes it a profitable option, assuming you want to join the society as cheaply as possible. The tower is very tall (higher than a Space Shuttle) and not likely to fall down any time soon, which is good. It needed a door to make it harder for people to climb to the top and fall off, and doesn’t actually hold water at the moment, but it all made for a very enjoyable story told in a very engaging way.

 After a burger lunch (very nice) it was time for my namesake to talk about the dangers of Artificial Intelligence. If we make a device that is clever enough to be useful, will it also be clever enough to be dangerous? It was a timely talk, what with the rapid advances in the field and the tendency of humanity to rush into technology without thinking about the consequences.

Then it was time for some hard-core hardware, in the form of a very detailed description of the creation of silicon devices that contain more than just transistors. It turns out that we can put all kinds of sensors directly onto the silicon and even make them small enough to be swallowed and take pictures during their journey through our system.

Next came a description of algorithmic light displays. I've been doing these since my discovery of Neopixel technology and my wedding lights of many years ago. However, the speaker was operating in a slightly different league, with huge displays containing hundreds of lights. There was some very interesting content about gamma correction and the proper use of randomness. Very interesting.

By now my brain was pretty much full for the day, but there was just enough space to take in a description of the project that is recreating one of the first ever stored program computers, the EDSAC project

After that it was dark, which made it a perfect for tying some Light Painting/Light Writing. Everyone else turned up with proper camera on huge tripods. I just had my tiny Sony camera and a table top tripod. However, after literally shaky start, when I fell over onto the grass after setting up the camera, I got some pictures that I'm not too unhappy with. 

42590800890_c81e9b908d_k.jpg

We got some nice looking results with some tiny lights on strings. But then a chap turned up who just happened to have hundreds of leds on a pole. Electromagnetic Fields is that kind of place. And the pictures got even more fun. 

30531828288_64f441b9e2_k.jpg

After that it really was time for bed. So, after picking our way through guy ropes and power cables we found our way to our tent and turned in, the best kind of happy-exhausted and with the prospect of even more fun and games tomorrow.

This is big news. Oh. Ahem.

THIS IS BIG NEWS.

Microsoft are rolling out an Insider Dev Tour next month. There are around 30 events all over the world, with 2 in the UK. One in London and one in Manchester.

I'm very pleased to be able to report that I'll be presenting at the Manchester event next month, on the 20th of June. I'm doing a session on Machine Learning, really looking forward to it. You can find out more about the Insider Dev Tour here. You can sign up for the Manchester event here

Comicon 2017

24651341138_d3063d3d85_z.jpg

Ever since happy times spent at the Collectormania events in Milton Keynes many years ago, I've had a hankering for a bit more comic book madness. So today we headed off down the motorway to Comicon 2017 at Birmingham. It was great.

There were lots of people in "cosplay", which I guess is a posh name for "dressing up", but some of the costumes had to be seen to be believed. There were even entire families heading out in character. The atmosphere was great, and I even ran into a bunch of ex- students. At a Comic Book conference? Who'd have thought?

It was great fun, and I'd love to go again next year. There were some really impressive "steam punk" outfits around and I fancy having a go at that.....

Rob at "Pint of Science" on Monday Evening

I'm doing a bit of talking tomorrow night. It's as pat of the "journey inside the human body" part of the "Pint of Science" talks in Hull. I'm going to be talking about whether or not we can make "Artificial Brains".  It's a look at artificial intelligence, computer software, killer robots and what we should really be afraid of.

And there are giveaways. You can sign up here. (please note that the 37 on the screenshot above might be out of date soon - especially when people find out that I'm coming along....)

Tick Tock Unlock Fun and Games

 I can't post any pictures of the puzzles or the room, but they did have this rather nice Tesla in one of the arcades in Leeds..

I can't post any pictures of the puzzles or the room, but they did have this rather nice Tesla in one of the arcades in Leeds..

Went to Leeds today for another birthday treat. We had booked a go at Tick Tock Unlock, a locked room escape experience where you have an hour to complete a mission which involves puzzles, cooperation and some really cool padlocks. 

It was great fun. There were five of us and I like to think that we turned into a well-oiled puzzle solving machine. We managed to get out within the the allotted hour and the chap in charge reckoned that we did really well, only needing three clues. (but I bet he says that to all the groups).

The setup is very smooth and well organised and the puzzles themselves are nicely paced so that you get plenty of things to do as you piece together the clues that will get you past the final door.

If you are looking for a novel experience which is great fun then you should have a go. We'll certainly be having a go at another one. 

BJSS at Hull

BJSS are a great bunch of folks. I can say that because I've met quite a few of them. They came over to Hull from Leeds to run a programming challenge event type thing in our computer labs. With free pizza and drinks. It was excellent. They posed an interesting task and the students who came along set about solving it. Then they wandered around giving comments and advice on coding and having chats about CVs etc. 

It was great to have a professional perspective on problem solving. I even had a little go myself, until my natural laziness took over and I reverted to chatting with the BJSS folks about board games and stuff.  As you do. 

The students that came along had a great time, and any time BJSS want to come by it would be lovely to see them again. 

Rob != Winner

Well, my suspicions were correct. Three minutes of unfocussed content does not a Famelab winner make. Even if you add a gadget.

I got the email today saying that I've not made the top six. I'm actually quite relieved about this. From what I saw of the entrants we have some proper science folks who are keen on presenting the subject that they are passionate about. The local final is in Hull soon. You can find out more here, and I'd advise you to go along if you can.

Famelab Beckons. Or not.

 A not so secret weapon

A not so secret weapon

Today was the day that I made my Three Minute Pitch for fame at FameLab. The idea is that you speak about something scientific for three minutes. No more. No less. No computers, no script. Just you and 180 seconds. 

Of course I cheated.

Turns out that you are allowed props. The night before the talk I put together the little device you can see above. It uses LittleBits devices to create a timer. It uses two rows of lights that increase as the time goes by.The bottom row fills up over the three minute and the top row fills over the last thirty seconds. It was actually quite fun to make. I used the Arduino LittleBit to make it work. I'll post the program later. 

The timer worked out fine, but I don't think I've made it to the final. Everyone else was doing hard core science stuff, you know, origins of the universe and serious stuff like that where I just did my piece about how Computer Science is the bestest ever subject.  I think if I want to make it in this field I need to come up with some slightly more focussed content. 

Anyhoo, the great thing for me was to see lots of enthusiastic people talking science in front of an appreciative audience. Great stuff. 

Careers and Internships Events at Hull

Gaming: 27th January 2016 12:30 pm - 4:30 pm

Development: 24th February 2016 12:30 pm - 4:30 pm

There is still time to register for the two events we are holding this year. The Gaming one is next week  and the Development one runs in around a month or so. 

These events are for students at Hull University who want to find out just what software development is going on and meet up with the folks doing it. If you are a First or Second Year you should be looking for internships and summer placements. If you are a Third or Fourth year you should be talking to people with a view to employment. There is a lot going on in the development space and this is how you can become part of it. Everyone who attends as a conference delegate will get a set of business cards and some other conference goodies. We'll have talks from industry and stands from companies. And maybe some free pens.

Register here by 12:00 on Monday 25th of January to take part. 

Enter FameLab - I have

I've signed up for FameLab. I think you should too. Being able to handle yourself in front of an audience is a terribly useful skill. If you are going to start, it's best to start small. FameLab gives you three minutes to fill with something scientific that you feel passionate about. The Hull heat is on the third of February 2016 and you can find out more and sign up here

I'm going to speak about why Computer Science is the most important subject of all. Should be fun. 

Tiny Christmas Bash

We had the smallest Christmas Bash ever this year. I think this was mostly due to poor planning on my part. Our bash clashed with an excellent, and very well attended, event organised by Hull ComSoc. 

Anyhoo, pizza, mince pies, crackers and fun was had. We played a bunch of silly games, including the awesome Masquerade, a newcomer called Two Rooms and a Boom (which is great fun). Exploding Kittens, Skull and the ever popular Coup

There was so much going on that we managed to overrun by an hour. More bashes next year. 

Fun and Games at the Black Marble Event

 Some of the audience. And some of my toys...

Some of the audience. And some of my toys...

Black Marble are a great company. The do lots of splendid free events for software professionals. And, since they've booked a venue and sorted out all the logistics, they run sessions for schools and colleges at the same time. They get a bunch of speakers and we talk about technical and professional issues. I've been lucky enough to be invited to present a few times, in the past I've taken Una my 3D printer along, amongst other toys. 

Today I didn't really do a technical talk. Although we had some technology of course. I was more concerned with the business of making a name for yourself. My line on this is that advancing technology is replacing many of the jobs that we used to do. It seems to me that in the future you'll have to get used to changing what you do as machines get better and better at doing things that people do at the moment. This means that the only thing that will be constant during your career will be the brand that is you. I've gave lots of tips about building your brand; you can find the slide deck here.

During the talk I also touched on fun things that you can do including playing with the Arduino embeded device. I said I'd put some links to resources. The Arduino I'd recommend is a kit from Sintron which you can get from eBay. Just search for Arduino Sintron. It's around 25 pounds and really good value:

There are loads of resources on-line, once you've got the kit they send you a link to lots of them. There are some Arduino tutorials here that I wrote a while back.  You can get my C# Yellow Book here

I did my session twice, but I only remembered to take picture of one small part of the audience. Sorry about that. Anyhoo, thanks to Linda and Boss for setting up such a great event. Great fun.

 I promised a panorama of the entire second sitting audience, here they are

Super Smash Christmas Bash

Today we had our Christmas Bash. This is usually a fairly quiet and select gathering, what with a lot of coursework being due and folks going home for Christmas. But we still found enough people to get through 128 pounds worth of pizza, which is a success of sorts....

Thanks to Adam and his advance purchasing power this event had a strong Super Smash Bros theme. He had managed to get a complete set of amiibos as prizes (including the much sought after Villager amiibo) and set up a tournament for folks to win them. We also had the lovely folks from Platform Expos with their network of Xbox One consoles playing Titanfall. Lob in Halo collection, Super Mario Kart and a wordsearch and you get a pretty good night's worth of entertainment. 

 A tense moment in Titanfall

A tense moment in Titanfall

If you have any fears about the survival of Nintendo or the future of their Wii U console I really don't think you have much to worry about. From the reaction to the 8 player action (and the fun I had playing it too) I reckon they are going to be fine. One hard core PC gamer left with a newly acquired amiibo and a plan to try and get a console for Christmas. Great stuff

 The winners with their prizes

Of course we had a wordsearch. Of course some people came along, sat down with it and spent all their time finding words. And one of them won a prize.

 A worthy winner, but still some words left to find...

A worthy winner, but still some words left to find...

We were having so much fun that we forgot about the timings and the event ran on for quite a while after the finish time. And we will definitely be having another Super Smash Bros session next year. There are more pictures of the event on Flickr. You can find them here

Christmas Bash is Coming

The Christmas Bash for 2014 is coming and it is going to be a corker. We are going to have Wii U Smash Bros 8 player, with amiibo prizes, Team Fortress 2, Xbox One, Playstation 4, board games, word searches, pizza, mince pies and a super bumper hyper mega wordsearch which might include the words super, bumper,hyper and mega.

Tickets will be on sale in the Departmental Office on the Third Floor of the Robert Blackburn Building from 2:30 pm on Monday 8th December. Numbers are strictly limited.
