Tony Whitmore: Wedding photographer, broadcaster, documentary maker, IT geek

August31

Before I start, I should declare a potential conflict of interest: Tony Whitmore is my other half, and has been for the past 12+ years.

Tony's face
That doesn’t mean I blindly think he’s great at everything even when he isn’t. He has his faults. And he does daft things at times, like occasionally forgetting to press Record when we do an Ubuntu-UK Podcast show; though even then, he’s usually planned for such an eventuality (he has a backup recording of the stream running on his VPS).

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.

The brilliant fun that is OggCamp probably wouldn’t have come about without Tony’s planning ability. As fellow UUPC-founder Alan Pope says “the podcast would almost certainly not exist” either. That’s not to say that Tony has done either of those things alone. Alan, who came up with the original idea for UUPC, is probably the creative genius of the project – coming up with a lot of the content ideas over the past 4 years and typically thinking up wacky ideas on his 50 mile drive to our house to record the show. OggCamp’s organising team is pretty big and varies from year to year but Tony’s hand is usually firmly on the budget, making sure we break even (for which I’m sure we’re all grateful as the event is financially underwritten by the individuals on the two podcast teams).

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 Dolby Digital EX rear speaker with Dave M 

  • 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.

As usual, he practised and did a lot of research, including watching tutorials by the awesome Jasmine Star. Jasmine’s focus is only partly on the photography; she talks a lot about the business side of being a wedding photographer. And at the start of this year, Tony decided he was going to give it a go. He went on Jasmine’s course when she came to London in July, and he attended a few of the free courses offered by the HMRC.

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.

Mosquitto and Facebook…and OggCamp

August17

Roger Light (@ralight) has just posted on his blog that Facebook are using MQTT for their new messaging system and, specifically, they seem to be using some part of Roger’s Mosquitto project in it.

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!

1 week till OggCamp 11!!!

August6

It’s just one short week until OggCamp 11! Each year we’ve done this event, it’s grown. This year has a really special feeling about it.

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:

We’ve got some exhibitors, including

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:

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!

Promoting research ideas with social media: A nice example

August3

So you’re a researcher and you want to get your cool new idea out there. You want other researchers to adopt it and promote it further for you. What do you do? (Hint: if you’re as cool as your idea, you probably mention The Web, Facebook (or Google+, if you prefer), and Twitter at this point, even if you secretly wonder what they are and what the point of them is.)

In the past…

Traditionally, you would probably publish papers about your idea in peer-reviewed academic journals so that people interested in that area would read about it and think “that’s a cool idea; I must adopt that approach too”. Similarly, you might present about it at conferences where your audience of like-minded people would listen and think “that’s a cool idea; I must adopt that approach too”. If you had teaching responsibilities, you likely also taught your students about your new approach, explaining the weaknesses of the old approach and why this new approach is better so that when they come to doing their own research projects they think “that’s a cool idea; I must adopt that approach too”.

Except (I’m guessing here) it probably doesn’t always work like that. Especially if your cool new research idea is a statistical method. Especially if your new statistical method requires its users to sit down with a calculator and manually work through an equation instead of just opening a data file and pressing some buttons in SPSS, the statistics package popular with psychologists, marketing people, and others.

Calculator
I work in usability and user experience in my non-student life. But it doesn’t take a usability expert to work out that if your audience is made up of people who most likely have just GCSE-level (high school) Maths (like me) and often (I’ve noticed) The Fear of all things mathematical, you’re not going to get far in convincing them to use your new statistical method, even if it’s what they really need to use and they would actually quite like to use it. I don’t really have The Fear myself but I do glaze over when presented with less-than-simple equations and strange clusters of weird characters because I just don’t know how to read them.

The unfortunate upshot is that your cool new statistical approach just doesn’t really get off the ground, no one else writes about using it (so you don’t get the all-important citations in other people’s publications), and it just slides quietly away into the ether.

In the 21st C…

If you are as cool as your cool new research idea, you might also embrace the wonders of the world of social media and online communications. Obviously, publishing in peer-reviewed journals, presenting at conferences, and teaching your students are all good and necessary things to do. But they’re probably not enough in some cases–and I’d guess that statistical methods is probably one of those cases.

I don’t know whether Hayes & Preacher (or Preacher & Hayes) went through that exact thought process when thinking about how to promote their cool new statistical methods to psychologists and other social scientists, but it seems that usability was one of their aims (for example, Andrew Hayes suggests that people have tended to stick with the older methods, rather than adopt the newer and better methods, because the old ones are “simple and widely understood”; Hayes, 2009, p 411).

Facebook Discussion list of topics
So Hayes & Preacher have done two things:

  • Written macros to extend SPSS
    Users can use the macros to (fairly) easily run the tests using SPSS, an environment they’re already familiar with. Macros are a bit fiddly to work with so, for one of their tests, they’ve even written a custom dialog that you can install in SPSS which adds a new entry to the Analyze menu so that you can just open a standard-looking dialog box to select the appropriate variables names and run the test. All this is available for free download from their website.
  • Created a Facebook group to answer questions
    You can start a new topic (thread) to ask a question or describe a problem, or you can browse the existing 1636 (and rapidly rising) topics (at least, I’ve been able to before but today it seems the back/forward links have gone walkabout). You can also use Google to search for specific topics. Both Preacher and Hayes typically respond to questions and problems within a day. When I was having some technical problems, they asked for a my data file and ran the test on their own machines to check whether it was just my installation of SPSS that was the problem (it was).

Benefits for users

As a student trying to understand the statistical procedures by reading and re-reading their journal papers multiple times, it was invaluable to be able to ask the authors themselves (via Facebook no less) to clarify specific details as they applied to my particular experimental design. Browsing the 1000+ topics of discussion was also very educational as I came across answers to questions that I hadn’t even thought to ask yet.

Benefits for them

The benefits for them are surely great too. Obviously they have to spend time writing, testing, and supporting their macros etc, and they also have to spend time responding to help requests on Facebook. In return, though, they vastly improve the ease of using their statistical procedures, while also giving you (the user) a warm and fuzzy feeling about the procedures (the power of positive affect) and that there are many other people out there trying to use the procedure too (the power of social norms), all in all making you (I would guess) more likely to keep trying and to talk about the procedures to others. Those are the intangible and difficult-to-measure benefits of a good user experience.

In addition, they’re getting loads and loads of feedback from their users on where their procedures or explanations are difficult to understand, or where users commonly have problems, so that when they write a book on it, they’ve got valuable material to respond to and include which should make the book incredibly useful to users. We’ll see if that’s true when their book, and accompanying new macro, comes out next year. And there’s another thing, while they’ve got you in a discussion on Facebook, it’s practical (but also good promotion) for them to refer you to one or other of their papers, or to mention the book coming out next year. And there’s a list of up-coming events at which they’ll be conducting workshops on these statistical procedures. It all helps to boost citations.

Everyone wins

I think it’s brilliant. Not just because they helped me by answering a question within a day and diagnosing the problems I was having running their macros. But because they’re tapping into resources that are free and much of their target audience already use. And by doing this, they’re making their cool ideas as accessible as possible, which can only really be a good thing for everyone concerned.
