A couple of weekends ago, we went to the Doctor Who Official Convention (#dwcuk) in Cardiff. While one of the three main panels featured the three stars, Matt Smith, Karen Gillan and Arthur Darvill (along with executive producers Stephen Moffat and Caroline Skinner), most of the other scheduled events were focused on how Doctor Who is made.

At the very start of the day, we went to see Danny Hargreaves blow things up talk about the Special Effects on Doctor Who. In his Q&A session (after making it snow indoors), the first question asked was “How did you get into special effects work?” and, between questions like how he blew up the Torchwood Hub and how he makes the Doctor’s hands and head fiery during a regeneration, a later question was “When did you realise you wanted to work in special effects?”. Attendees were interested not just in the fictional stories and characters but in how the programme is made and the interesting careers they might not otherwise have come across.

Throughout the day, I heard audience members ask how to become costume and prosthetics designers and how to become script writers. Danny described how his team designs and creates the effects, assess the risks of blowing things up, and who they work with to make it all happen. He also explained how he came to be a trainee in the nascent world of special effects before studying Mechanical Engineering so that he could build the devices they need for Doctor Who (and the other shows he’s worked on, like Coronation Street). Directors of photography, set designers, executive producers, writers, and directors went on to talk about what their own jobs entailed day-to-day and how it all comes together to make an episode of Doctor Who.

These discussions continued the story that used to be told after each new episode of Doctor Who by Doctor Who Confidential on BBC3. Doctor Who Confidential started in 2005 with the return of Doctor Who. As well as talking about some interesting perspective on making that night’s episode of Doctor Who, it featured interviews with, and ‘day-in-the-life’ documentaries about, the actors (including showing the less glamorous side of shivering in tents and quilted coats between takes), the casting directors, the producers, the writers, the choreographers, the costume designers, the special effects supervisors, the monster designers, the prosthetics experts, the directors, the assistant directors, and many, many others. It also held competitions for children to write a mini episode and then see the process of making it, which would’ve been an amazing experience!

Yes, it took a slightly odd turn in the last series when it turned a bit Top Gear by showing Karen Gillan having a driving lesson and Arthur Darvill swimming with sharks; possibly a misguided attempt to increase its popularity before it got canned anyway to cut costs.

I think it’s a real shame to lose Doctor Who Confidential and its insights into the skill, hard work, and opportunities in TV and film production.

If you compare it with the average daily gas usage graph below, you can see (just from the scales of the y-axes) that we use much more gas than electricity (except in 2007, which was an anomalous year because we didn’t have a gas fire during the winter so we used a electric halogen heater instead):

Our gas usage has come down overall since 2005 (from 11280 kWh in 2005 to 8660 kWh in 2011; or 31 kWh per day to 24 kWh per day on average) but not so dramatically as our electricity usage has. Between 2005 and 2011, we reduced our electricity usage by about a half  and our gas usage by about a quarter.

Gas, in our house, is used only for heating rooms and water. So if I were to chart the average outside temperatures of each year, they’d probably track reasonably closely to our gas usage. In 2005 (when we used an average of 31 kWh per day), we still had our old back boiler (with a lovely 1970s gas fire attached) which our central heating installer reckoned was about 50% efficient. In 2006 (26 kWh per day), we replaced it with a new condensing boiler (apparently 95% efficient) but didn’t replace the gas fire until mid-2007 (the dodgy year that doesn’t really count). In 2006, we also had the living-room (our most heated room) extended so it had a much better insulated outside wall, door, and window. These changes could explain the pattern of reducing gas usage year by year up till then.

In 2009, January saw sub-zero temperatures and it snowed in November and December. I think that must be the reason why our usage for the whole year shot back up again, despite the new boiler, to 31 kWh per day. In 2010 (21 kWh per day), it was again very cold and snowy in January; I think the slight dip in gas usage that year compared with both 2008 (25 kWh per day) and 2011 (24 kWh per day) was down to a problem with the gas fire that meant we used the electric halogen heater again during the coldest month. In 2011 it snowed in January but was fairly mild for the rest of the year.

I think 2008, 2010, and 2011 probably represent ‘typical’ years of heating our house with its new boiler and gas fire. Like I concluded about reducing our electricity usage, I think our gas usage went down mostly by getting some better insulation and a more efficient boiler but we did also reduce the default temperature of our heating thermostat to about 17 degrees C (instead of 20 degrees C) a couple of years ago too (we increase it when we need to but it stays low if we don’t), which I think has made some difference but it’s hard to tell when our heating usage is so closely tied to the outside temperature. Also, we don’t currently have any way of separating out our water heating from our central heating, and our gas fire from the boiler.

Of course, what really matters overall is the total amount of energy we use (that is, the gas and electricity numbers combined). So I’ve made a graph of that too. Now we’re talking numbers like 48 kWh per day in 2005 to 33 kWh per day in 2011.

Overall, that means we reduced our total energy usage by about one-third over seven years.

Thanks again to @andysc for helping create the graph from meter readings on irregular dates.

I’d just been whinging on Twitter about how European governments need to open up their railway data so that companies can set up better pan-European rail booking websites so that it’s easier and cheaper to book journeys that cross multiple countries. And @pete_v replied that he’d used Deusche Bahn:

So I gave it a go. I typed in Southampton Airport Parkway (UK) as the starting point and Aarhus (Denmark) as the destination. Not only had it heard of both stations but it even did text completion on their names! I made up some dates, clicked Search, and within less than a second it had returned a list of possible trains:

And at the click of a button, the full itinerary:

It also provides a comparison with travelling the same distance by car (includes full route planning details and a map – not shown here):

And an environmental report comparing, among other things (not all shown here), carbon emissions from flying or going by car, which is something I think is really useful too:

So, in summary, I think this is a rather cool site! I’ve not yet tried booking anything and you can’t do that online (or at least, not for such a complex journey) but you can book the complete journey by phoning up. You also can’t here see the price (though I have a fair idea of what it’s likely to be based on having played around with individual sites like Eurostar and the Danish railway bookings site) so that would have to be kept as a surprise for when talking to the agent. Presumably, also, it’s not checking actual availability (it’s so quick I don’t think it could be doing) so there are potentially several more steps to go.

But it’s still loads better from a user experience perspective so far than using Rail Europe, or even Eurostar, which throws errors a lot more often than it should. Those two sites, while slow, do at least provide online booking. So Deutsche Bahn still has something to prove. If I do end up going to Aarhus (or elsewhere), I’ll give it a go and report back!

P.S. I also haven’t tried taking a detour through Copenhagen so that I can do a The Killing tour…that should be a real test of it…

In 2007, we used 6783 kWh of electricity (for electricity, a kilowatt hour is the same thing as a ‘unit’ on your bill). In 2011, by contrast, we used 3332 kWh (or ‘units’). 2007 was slightly on the high side (compared with 2006) because we had no gas fire in the living-room during the winter of 2006-7 so we’d used an electric oil heater during the coldest weeks (we don’t have central heating in that room) ¹.

That’s an average of 19 kWh per day in 2007 compared with 9 kWh per day in 2011. Which is quite a difference. So what changed?

In early 2008, I got a plug-in Maplin meter (similar to this one) and one of the very early Current Cost monitors, which display in real-time how much electricity is being used in your whole house:

Aside from the fun of seeing the display numbers shoot up when we switched the kettle on, it informed us more usefully that when we went to bed at night or out to work, our house was still using about 350 Watts (which is 3066 kWh per year)² of electricity. That’s when the house is pretty much doing nothing. Nothing, that is, apart from powering:

• Fridge
• Freezer
• Boiler (gas combi boiler with an electricity supply)
• Hob controls and clock
• Microwave clock
• Infrared outside light sensor
• Print/file server (basically a PC)
• Wireless access point
• Firewall and Internet router
• DAB clock radio
• ADSL modem
• MythTV box (homemade digital video recorder; basically another PC)

And that’s the thing, this ‘baseline’ often makes a lot of difference to how much electricity a house uses overall. 3066 kWh per year was 56% of 2007′s total electricity usage.

The first six items on that list draw less than 100 Watts (876 kWh per year) altogether. They’re the things that we can’t really switch off. But there were clearly things that we could do something about.

Over the next couple of years, we reduced our baseline by about 100 Watts by getting rid of some of the excessive computer kit, buying more efficient versions when we replaced the old print/file server and MythTV box, and replaced most of our lightbulbs with energy-efficient equivalents. We also, importantly, changed our habits a bit and just got more careful about switching lights off when we weren’t using them (which wouldn’t affect the baseline but does affect the overall energy usage), and switching off, say, the stereo amplifier when we’re not using it.

That brought our baseline down to about 230 Watts (2015 kWh per year), which is a lot better, though it’s still relatively high considering that the ‘essentials’ (eg fridge and freezer) contribute less than half of that.

And that’s about where we are now. We tended to make changes in fits and starts but none of it has been that arduous. I don’t think we’re living much differently; just more efficiently.

The problem is that the 60,000 products listed in the Good Guide are US brands. We guessed that some would be common to the UK though. We wondered if it would be possible to match the Good Guide list against the Amazon.co.uk product list so that we could look up the Good Guide information about those products at least. Unfortunately, when we (Andy) tried this, we discovered that Amazon uses non-standard product IDs in its site so it wasn’t possible to match the two product lists.

The equivalent of the Good Guide in the UK is The Good Shopping Guide, of which we had an old copy handy. The Good Shopping Guide is published each year as a paperback book which, while a nicely laid out read, isn’t that practical for carrying with you to refer to when shopping. We discovered that The Ethical Company (who produce the Good Shopping Guide) have also released an iPhone app of the book’s content but it hasn’t received especially good reviews; a viewing of the video tour of the app seems to reveal why.

By this point it was getting on for midnight and the two coders in our team, Andy and Alex, had got distracted hacking a Kindle. Alex and I, therefore, decided to design the mobile app that we would’ve written had we (a) had access to the Good Shopping Guide API and (b) been able to write the code needed to develop the app.

While we didn’t have an actual software or hardware hack to present back at the end of the hackathon weekend, we were able to present our mockups which we called our ‘UX hack’ (a reference to the apparently poor user experience (UX) of the official Good Shopping Guide mobile app). Here are the mockups themselves, along with a summary of the various ideas our team had discussed throughout the first day of the hackathon:

I rather like the crisp freshness of physical new books and the battered usedness of secondhand books, with their mysterious inscriptions from owners (or libraries) past. I also quite like having physical books on shelves; I grew up in a household full of bookcases and I’m easily distracted, when visiting friends, by the contents of their bookcases. But our current small house can’t really take many more shelves.

I’ve found that having a pile of books-to-read by my bed doesn’t actually make me read them any more quickly. And the weight and bulk of them prevents me carrying one around with me on the off-chance that I might have a spare moment to read it. I read Incidents in the Life of a Slave Girl whenever and wherever I had the chance: on the train, on the station platform, on car journeys, at my in-laws, in the living-room waiting for tea, in the kitchen whilst cooking tea, in bed, in the middle of the night when I couldn’t sleep. In short, anywhere I had my phone and some free time. And I carry my phone everywhere.

The problem with my phone is that it’s not that comfortable to hold for a long time and I’m a bit wary of straining my eyes focusing on such a small, backlit screen. Handily the Kindle automatically syncs your reading position (in the book; not your posture) to the Amazon server and your other registered Kindle devices. So if I had a Kindle, I could read it at home or on the train, and then, when I don’t have the Kindle with me (eg waiting to be served at the takeaway), I could carry on reading the same book from my phone.

So a Kindle is now on my Amazon wishlist. I’m not keen on the closedness of it as a system but I do like the user experience. Just got to patiently wait for my birthday to come round now…

Thank you for your time!

He’s quite good at planning.

The first time I met his family, his brother Mark joked that we probably had a written schedule for meeting their grandparents and other family members. Mark was wrong. It wasn’t a joke. We actually did. Tony’s Sunday roast dinners used to get their own Gantt chart.

Alan, and all the HantsLUG guys we’ve known since moving to Hampshire, would probably agree that Tony’s planning and his lists are pretty epic but it generally gets things done (except when trying to get his phone to work at FOSDEM).

I think the thing that impresses me most, though, is that once he’s decided to do something, he gets on and does it to his best ability and that thing is pretty much always a success. Things like:

• Installing an all-new Dolby Digital EX sound system at Lancaster University FilmSoc (including wiring up the new rear speakers and reorganising the projection box so all the new kit would fit). The engineers were astounded, when they arrived, to find that the physical installation was complete and they were mostly just needed to calibrate it.
• Teaching himself Linux well enough that, for a long time, his website howto was the first hit whenever you searched for Core Linux, and he quickly settled in to HantsLUG as one of the people you went to for help with your Linux installation.
• Producing the Ubuntu-UK Podcast (which has had over 1.5 million downloads since it started in 2008), honing his audio production skills (and buying lots of new toys).
• Devising and producing the amazing documentary that is Don’t Listen Alone. I just love it!

His latest project is too young yet to judge its overall success but I have faith because he has form. Last month, he set up Tony Whitmore Weddings, his new wedding photography business. He’s always enjoyed photography, crafting photos with technical precision and artistic flare. Inspired by our friend James Hodgson‘s Christmas present to us, Tony decided to set himself a photo project a couple of years ago where he had to take enough photos in 12 months that he could produce a calender to give as Christmas presents the following year. On the back of that calender, he got his first wedding photographer gig.

Last weekend, he launched his business website (with logo kindly donated by my new cousin Jeff and his funky graphic design skills) and Facebook page, and he already has not only a reasonable portfolio but also bookings for future weddings.

I think he’s amazing – but then I would. I don’t think I’m alone, though, in having a huge amount of admiration for what he achieves when he sets his mind to something.

So why is this a big deal to me?

Last weekend was the third OggCamp conference, OggCamp 11, at the Farnham Maltings in Surrey. Two years ago, at the first OggCamp (a one-day event at the Connaught Hotel in Wolverhampton), we invited Andy Stanford-Clark (@andysc) to be our opening keynote speaker. Andy co-invented the MQTT messaging protocol about 10 years earlier and, while there was a server implementation of MQTT (Really Small Message Broker; RSMB) that you could download for free from IBM’s website, it was proprietary and there was no open source implementation available.

Andy wrote a new presentation, especially for OggCamp, describing the geeky innards of his Twittering house (as seen earlier that year on the BBC). The presentation was a fantastic kickstart to the day and (somewhat predictably for a conference with its foundations firmly in the open source world) Andy was questioned about what bits of his home automation system were built on open source software and open standards. The one significant part of the system that was proprietary was RSMB (the core part that enabled all the parts of his house to communicate).

Then OggCamp started, we had a good time, and we went home exhausted but happy.

And then, just two weeks later, Roger announced that he’d registered a new project called Mosquitto (as in MosQuiTTo) on Launchpad. He’d been inspired by Andy’s talk at OggCamp to write an open source alternative to RSMB. Within what seemed like days he had a working bit of code which was taken up and tested by others in the open source community and hardware-hacking communities like Homecamp.

I cannot claim any credit at all for all the hard work that Roger and others put in developing and testing Mosquitto. I’ve always been proud, though, that Mosquitto was born at OggCamp – we played our small part in helping connect the previously mostly corporate/business MQTT with the open source communities.

That Facebook announced they were adopting MQTT for their new messaging system the day before OggCamp 11 meant we could vicariously revel in Roger’s glory while we tried to find out just whether Facebook had adopted his code or their own implementation. The answer seems to be somewhere between the two.

And while I’m proud for OggCamp (of course), I’m also excited for Roger in his own right that his name is now in the licence agreement of apps from the mighty Facebook – that kind of recognition for your hard work must be such an amazing feeling!

It’s brilliant that there are people who have taken the event name literally and are camping for the weekend. Hopefully the weather will favour them! The Farnham Maltings venue has a really nice feel to it and is ideally located for the park and pubs. The attendees at OggCamp really make the event what it is and the best bit (well, one of them) as an organiser is seeing everyone arriving at the venue on Saturday morning!

We’ve got three stages, two of which are being run as an unconference. That means that the wonderful OggCampers volunteer talks and others vote for the ones they’d like to see most! We’ve had some really great talks submitted this way in the past. It sounds a bit chaotic and it is, but it works! We’ll be using CampFire Manager by Jon Spriggs to schedule these talks for the first time this year so you’ll be able to propose and vote for talks by txt msg and see the schedule up on the digital displays around the venue.

Our main stage schedule is basically complete. The Ubuntu Podcast team will be joining forces with the Linux Outlaws for the traditional live podcast recording. There will be a panel discussion and a raffle (of course) too! Our wonderful main stage speakers include:

• Simon Phipps
• LornaJane Mitchell (careers in Open Source)
• Chris Gutteridge (Southampton OpenData project)
• Steve Lee (Accessibility)
• Wayne Myers (professional music production on Linux)

We’ve got some exhibitors, including

• O’Reilly (who are offering 40% off their books on the Saturday)
• Free Software Foundation Europe
• Hacker Public Radio
• Ubuntu UK
• Reprap 3D printer

We’ve also got some surprises planned for the weekend which you’ll only find out about by being there. If you want to come along and join in some or all of the weekend’s activities, you can. It’s free. That’s right, it doesn’t cost a penny. There are a few tickets left and you can get your hands on them here: http://oggcamp11.eventbrite.com

It’s free thanks to our lovely sponsors:

• Bytemark (our headline sponsor!)
• Google
• Chris Procter on behalf of lug.org.uk
• Bitfolk (sponsoring the Saturday night party!)

This week is always the quickest of the whole process. Before we know it we’ll be standing in the William Cobbett pub sharing a drink or two with the lovely OggCampers on Friday night and won’t touch the ground until after the Sunday night drinks! The plan for the weekend (and lots more information) is available on the OggCamp website.

One of the best parts of the weekend is meeting people who listen to the show, so please say hello! See you there!
